Description
Technical field
The present invention relates to the door lock assembly of a kind of cold-storage door, be specifically related to a kind of freezer horizontal sliding door security lock arrangement.
Background technology
Freezer is to utilize cooling installation to create suitable humidity and the warehouse of cryogenic conditions, also known as freezer, freezes storehouse or cold storage storehouse, can extend the shelf life of product, to regulate market supply.At present, cold-storage door generally uses double-wing door structure, and i.e. two, left and right door body is along slideway to pulling open or closing, and the outside of cold-storage door uses lock pin and padlock to pin, to reach antitheft purpose.But also having some cold-storage doors to use horizontal sliding door, i.e. door body and doorframe can be rotated relative to doorframe by gemel connection, door body, and then be opened or closed door body, the outside employing lock pin of cold-storage door and padlock pin, to reach antitheft purpose.Owing to door lock is in the outside of cold-storage door, cannot open cold-storage door at cool house internal, once carelessness will be locked in personnel in freezer, and trapped personnel is caused life threat.In order to prevent personnel to be trapped in freezer, it is necessary to can open cold-storage door in freezer, in existing freezer, to have the structure of this function the most less desirable for openable door lock, and some structures are more complicated, and fault rate is high, and cost is the highest；Although also have can open cold-storage door in freezer, but its theftproof performance decreases.Therefore, the applicant has applied for Chinese invention patent " freezer security lock arrangement " on February 3rd, 2015, Application No.: 201510054543.6, this freezer security lock arrangement uses button spanner and buckle ring structure, it is only applicable to the cold-storage door of double-wing door structure, owing to structure and the operation principle of horizontal sliding door are different from double-wing door, it is impossible to above-mentioned freezer security lock arrangement to be used for the cold-storage door of horizontal sliding door structure, accordingly, it would be desirable to develop a kind of cold-storage door safety lock being applicable to horizontal sliding door structure.
Summary of the invention
In order in solving existing freezer, openable door latch structure is complicated, cost is high and the problem of anti-theft difference, the present invention provides a kind of freezer horizontal sliding door security lock arrangement, this freezer horizontal sliding door security lock arrangement pull-up in freezer rocking arm of meeting an urgent need rotates 180 ° emergent portable plate can be made to move horizontally, and then make lock pin deviate from from doorframe lock ring, outwards push cold-storage door open, have the advantages that simple in construction exquisiteness, low cost and theftproof performance are good.
The technical scheme is that this freezer horizontal sliding door security lock arrangement, including lock pin, lock ring and doorframe lock ring, the locking plate suitable with locking nose it is fixed with on lock pin, also include the hold-down support being fixed in door body, described lock ring and lock nose are fixed on the front of emergent portable plate, and the back side of emergent portable plate is provided with dovetail groove and vertical guide groove, and hold-down support is provided with the line slideway suitable with dovetail groove, vertical guide groove is vertical with line slideway, and emergent portable plate can linearly slide；Being provided with eccentric shaft on described hold-down support, on eccentric shaft, one end of corresponding emergent portable plate is provided with bearing, and bearing is positioned at vertical guide groove and can slide at vertical guide groove.
The other end of described eccentric shaft connects rocking arm; rocking arm is provided with sleeve and handle; be provided with spring and sliding pin in sleeve; taper knob is outer at sleeve and is connected with sliding pin; the inner side of hold-down support is fixed with ring flange; ring flange is provided with hole, location, and the right-hand member that sliding pin is positioned at when positioning hole portable plate of meeting an urgent need is concordant with the right-hand member of hold-down support, and when locking plate is interlocked with lock nose, lock pin penetrates in doorframe lock ring.
Described door body comprises shell and door shell in door, and in the inner side of hold-down support and door, shell fixes, and is hollow-core construction and inside is filled with insulation material in described door between shell and door shell and in door between shell and hold-down support.
When described sliding pin is positioned at hole, location, the left end laminating of emergent portable plate rides over the outer surface of door shell；Being equipped with groove on the top and bottom sidewall of described emergent portable plate, the door shell corresponding with the top and bottom sidewall of emergent portable plate extends in groove, and emergent portable plate can slide by door shell relatively.
Described ring flange is provided with two insurance holes, and two insurance holes are positioned at 45 °, both sides, hole, location angle range.
Described ring flange is provided with withdraws hole, and the angle withdrawn between hole with hole, location differs 180 °.
There is advantages that owing to taking technique scheme, under normal circumstances, under normal circumstances, sliding pin is positioned at hole, location, the right-hand member of emergent portable plate is concordant with the right-hand member of hold-down support, in when locking a door, lock pin penetrates into doorframe lock ring, locking plate is fastened on lock nose, hangs over padlock and locks on lock nose.If there being trapped personnel in freezer, trapped personnel pull-up handle, spring is compressed, sliding pin pulls out in hole, location, holds handle and rocking arm is rotated 180 °, and eccentric shaft rotates also with rocking arm, bearing upper and lower sliding in vertical guide groove promotes emergent portable plate to slide to the left, and then emergent portable plate band pendulum lock pin slides to the left, after lock pin is completely out from doorframe lock ring, pushes out door body and can open door body.Under normal circumstances, sliding pin is positioned at hole, location, and eccentric shaft turns, emergent portable plate cannot be made not to slide to the left in the outside of door body, has the advantages that simple in construction exquisiteness, low cost and theftproof performance are good.
