The specific embodiment
Below in conjunction with accompanying drawing the enforcement and the advantage of the utility model are done further to explain.
The explanation of the embodiment of relevant the utility model is graphic with reference to what add, can be in order to the specific embodiment of implementing in order to illustration the utility model.And the direction term of in utility model, being mentioned, for example " on ", D score, " preceding ", " back ", " left side ", " right side ", " side " etc., only be direction with reference to annexed drawings.These direction terms are in order to explanation and understand the utility model, but not in order to restriction the utility model.In following examples, in different figure, same section is to represent with same numeral.
With reference to figure 3.The utility model track train air-conditioning door closure opening structure 30 can be fixed on the train through upper support frame 31 and following bracing frame 32; This door closure opening structure 30 comprises gas spring 30 and connecting element 39; Connecting element 39 has two up and down; Structure is identical, respectively gas spring 30 two ends is connected on said upper support frame 31 and the following bracing frame 32.
Fig. 4 is the enlarged diagram of end A with gas spring 30 of connecting element 39.As shown in Figure 4, connecting element 39 is fixed on the back-up block 33, offers fixed orifice (not label) on this back-up block 33, and connecting element 39 is fixed through fixed orifice.In this embodiment, connecting element 39 is provided with retaining washer 36 by bonded assembly ball and cocket joint 34 and the nut 37 of cooperatively interacting through fixed orifice between said nut 37 and the fixed orifice.Said ball and cocket joint 34 is connected with the cylinder barrel 35 and the piston rod 38 of gas spring 30.
Refer again to Fig. 3.In one embodiment, the rivet hole that can to have three diameters on the following bracing frame 32 be 4.1mm will descend support frame to be fixed on the air-conditioning through rivet, on the bracing frame 32 fixed block 33 will be set down said then, and in like manner, upper support frame 31 can have identical structure.But as shown in the figure, upper support frame 31 also can be through directly welding said back-up block 33 on the strap stiffener of cover plate, and same, in certain embodiments, following bracing frame 32 also can adopt identical structure.That is to say that the utility model can be reequiped on the basis of round steel strut bar 10 or bayonet socket strut bar 20, use original mounting hole or increase conversion support and accomplish.Said fixed orifice can be set to manhole, and diameter can be 8.5mm.
During use; Supporting bracket 31 and following supporting bracket 32 in door closure reaches, welding or rivet on the dress plate earlier; Two ball and cocket joint 34 are installed on respectively in the through hole on supporting bracket 31 and the following supporting bracket 32; And fix with retaining washer 36 and nut 37, the cylinder barrel 35 and the piston rod 38 at gas spring 35 two ends is stuck on two ball and cocket joint 34, accomplish and assemble.
The elastic force of gas spring is that one-level increases progressively from 50N-500N with 50N, can calculate needed elastic force through formula according to weight and other parameter of door closure, selects the specification that is adapted to.For example, with reference to figure 5, G representes gravity, and S representes focus point; E representes fulcrum, if the weight G=180N of air-conditioning door closure, the arm of force L=222cm of gravity during standard-sized sheet; The arm of force W=142cm of gas spring elastic force during full cut-off, the number X of gas spring=2, then according to the elastic force computing formula of gas spring:
F=（G×L×1.15）/（W×X）
=（180×222×1.15）/（142×2）
=162
Drawing needed elastic force is 200N.
Certainly, more than only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other embodiment, and any modification of being done within all spirit and principles at the utility model is equal to replacement, improves etc., all should be included within the protection domain of the utility model.
