The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
Like Fig. 1, shown in Figure 2, the utility model comprises non-metal downside door-plate 1, non-metal downside door-plate 1 comprise be arranged on non-metal downside door-plate 1 around, and with non-metal downside door-plate 1 all-in-one-piece doorjamb 2 is set.The cross sectional shape that the left and right sides of non-metal downside door-plate 1 is provided with 3, two vertical dovetail grooves 3 in the outside of the vertical dovetail groove in an outside is identical, and symmetrical about the longitudinal centerline of non-metal downside door-plate 1; Be arranged at intervals with the vertical dovetail groove 4 in some inboards on the non-metal downside door-plate 1 between two vertical dovetail grooves 3 in the outside, the cross sectional shape of some the vertical dovetail grooves 4 in inboard is identical.The cross sectional shape that the both sides up and down of non-metal downside door-plate 1 are provided with 5, two horizontal trapezoid grooves 5 of a horizontal trapezoid groove is identical, and symmetrical about the cross central line of non-metal downside door-plate 1.Article two, the vertical dovetail groove in the outside 3, the vertical dovetail groove 4 in some inboards and two horizontal trapezoid grooves 5 are interconnected, and are the ladder-shaped that keeps flat.
Shown in Fig. 1～3; Article two, form between the vertical dovetail groove in the outside 3, the vertical dovetail groove 4 in some inboards and two the horizontal trapezoid grooves 5 two outside quadrangular types protruding 6 and some in the middle of quadrangular type protruding 7; Wherein, Two outside quadrangular types protruding 6 are symmetrical about the longitudinal centerline of non-metal downside door-plate 1, and quadrangular type protruding 7 is between two outside quadrangular types protruding 6 in the middle of each.On the non-metal downside door-plate 1 position of two outside quadrangular types protruding 6 be provided with vertically all being arranged at intervals with of 8, two outsides of folding quadrangular type protruding 6 some with folding 8 bonded assembly rivet holes 9; Adopt Bobtail tension rivet 10 to be connected between non-metal downside door-plate 1 and the folding 8.Be provided with a cushion block 12 in four dovetail grooves 11 of two foldings 8 and two horizontal trapezoid groove 5 formation, and all successively folding 8, cushion block 12 and non-metal downside door-plate 1 be connected through a Bobtail tension rivet 10.The afterbody of each Bobtail tension rivet 10 all outwardly, i.e. the afterbody of Bobtail tension rivet 10 and folding 8 be in same side, can avoid the goods in the afterbody scratch compartment of Bobtail tension rivet like this.
