Embodiment
The contrast accompanying drawing carries out detailed elaboration with the combination preferred embodiment to the utility model below.
A kind of plastic cement chuck comprises the plastic cement main body and is arranged on the groove on the plastic cement main body that two inner side surfaces of said groove include serrations, and the serrations of each said inner side surface is provided with at least two sawtooth.
A kind of chuck linkage structure comprises above-mentioned plastic cement chuck and section bar link, and said section bar link has the connecting head in the groove that is plugged into said plastic cement chuck, and the outer surface of said connecting head is provided with sawtooth, with the sawtooth formation engagement on the said groove.
Below specify two kinds preferred embodiment:
Embodiment one
The plastic cement chuck of present embodiment is a back sheet clip, and it is used for the connection between section bar and the sheet material, like Fig. 1, shown in 2; This back sheet clip 1 comprises plastic cement main body 11, be arranged on the groove 12 on the plastic cement main body 11 and be arranged on the plastic cement main body 11 at least one be used for the through hole 13 that sharp objects such as nail, screw pass through, the cross-sectional shape of said groove 12 is tapered, is equipped with the serrations 121 that continuous sawtooth forms at two inner side surfaces of groove 12; The degree of depth of whole groove 12 is 5-15mm; Wherein the length of each serrations 121 is 4-12mm, and the degree of depth of each sawtooth is 0.2-1mm, and width is 1-3mm; Said back sheet clip 1 can be by polyamide (Polyamide; Initialism is PA), acrylonitrile-styrene-butadiene copolymer (Acrylonitrile Butadiene Styrene, initialism are ABS), PVC (Polyvinylchloride, initialism are PVC), polycarbonate (PC) (Polycarbonate; Initialism is PC), polymethylmethacrylate (Polymethylmethacrylate; Initialism is PMMA) or polyethylene (Polyethylene, initialism are PE) etc. process, back sheet clip in the present embodiment 1 is processed by PA66.As shown in Figure 3; It is the schematic representation of the aluminium section bar pillar that can be used with the back sheet clip of present embodiment; This aluminium section bar pillar 3 is provided with two conical heads 31 that can be respectively cooperatively interact with the groove 12 of two back sheet clips 1; The outer surface of this conical head 31 is provided with sawtooth, and the sawtooth on its ability and the groove 12 forms convex-concave and cooperates.As shown in Figure 4; The schematic representation that connects aluminium section bar pillar 3 and sheet material 4 for back sheet clip 1; The conical head 31 of aluminium section bar pillar 3 is inserted in the groove 12 of back sheet clip 1, back sheet clip 1 and aluminium section bar pillar 3 are closely connected, the through hole 13 that passes on the back sheet clip 1 with screw or nail etc. makes back sheet clip be connected with sheet material 4; Thereby realize being connected between section bar and the sheet material, be used for the furniture assembling.Further, can two conical heads 31 of aluminium section bar pillar 3 be inserted respectively in the groove 12 of two back sheet clips 1, and each back sheet clip 1 and different sheet material 4 connect, and then realize being connected between sheet material and the sheet material.In a preferred example; Back sheet clip 1 comprises cell body, be wholely set at the base plate of cell body bottom and be positioned at the cell body two ends, to the side plate of cell body one side horizontal expansion; The cross section of cell body is on the whole for having the rectangle like at an arc turning and three right angles, and the cross section of groove 12 is arranged on arc turning and the minor face that the right angle defined, and the cross section of side plate is right-angled trapezium on the whole; Base plate extend two side plates trapezoidal base between, through hole 13 is opened on the base plate.This kind configuration is very favourable for the structural strength that improves the plastic cement chuck with the assembling steadiness.Two conical heads 31 of aluminium section bar pillar 3 are preferably and are symmetrical set, and insert respectively in the top groove 12 of two trapezoidal back sheet clips.
