The specific embodiment
Below in conjunction with drawings and Examples the utility model is given detailed introduction.
As shown in Figure 1 and Figure 2, the utility model is to be solidified by injecting glue by several parts such as adpting flange, end cap, vibration damping head, vibration proof mounting, overcoats to be assembled.
Adpting flange has two, can be referred to as adpting flange 1 and following adpting flange 2.For adapting to the shape and the structure of outer connector, and the best assembling effect that realizes flange and outer connector, the head of last adpting flange 1 and following adpting flange 2 be can be designed as various ways, be illustrated in figure 1 as the disc type flange, Figure 2 shows that the pillar flange, wherein the disc type flange is to be provided with flange in its end, and the end face of flange is provided with positioning boss 10 (as shown in Figure 1), is convenient to being connected of flange and connector like this.Head at last adpting flange 1 and following adpting flange 2 also is provided with the axial or radial flange interface 11 that matches with outer connector.
At the neck of last adpting flange 1 and following adpting flange 2, a sheathed end cap 3 has certain sheathed gap between end cap 3 and the flange neck respectively, is packed into rubber during assembling to realize that both is fixing in the gap.End cap 3 has external screw thread.
Afterbody at last adpting flange 1 connects a vibration damping head 4, connects a vibration proof mounting 5 at the afterbody that plays adpting flange 2, perhaps connects vibration proof mounting 5 on last adpting flange 1, connects vibration damping head 4 and also can on following adpting flange 2.Vibration damping head 4, vibration proof mounting 5 are threaded with the adpting flange employing or rivet, and add 6 stop of radial stop screw.The outside dimension of vibration damping head 4 and vibration proof mounting 5 is set in bore size on the adpting flange neck greater than end cap 3, makes end cap 3 be limited on the neck of adpting flange, can not deviate from from the adpting flange afterbody.
In the utility model, vibration damping head 4 and vibration proof mounting 5 are radially anti-rotation docking mode of inter-embedding type when cooperating, such as in certain embodiments, as shown in Figure 3, Figure 4, vibration damping head 4 and vibration proof mounting 5 are the cross recess structure, during butt joint, both slot parts and claw match grafting each other, and wherein the claw cross section of an end is trapezoidal, and the cross section of other end claw is rectangular, on direction of rotation radially, vibration damping head 4 and vibration proof mounting 5 will limit each other like this; Can also be on vibration proof mounting 5, to have some jacks, have some corresponding plugs on the vibration damping head 4, plug is inserted in the jack, cooperate each other.No matter but adopt which kind of mode, certain injecting glue gap all will be left in the docking site of vibration damping head 4 and vibration proof mounting 5 during assembling, comprises end play and radial clearance.
Because all have external screw thread on two end caps 3, therefore when assembling, in the internal thread that screws into overcoat 7 two ends with end cap, just can make vibration damping head 4 and vibration proof mounting 5 be protected in the inside of overcoat 7.Have hole for injecting glue 8 and spout hole on the overcoat 7, all leave enough injecting glue gaps between overcoat 7 and inner vibration damping head 4, the vibration proof mounting 5.
What deserves to be explained is, be equipped with center through wires hole 9 at the center of last adpting flange 1, following adpting flange 2, vibration damping head 4, vibration proof mounting 5.The outer lead of electronic building brick such as inserting tube, battery pack penetrates shock absorber from the adpting flange (as above adpting flange 1) of an end, center through wires hole 9 through vibration damping head 4, vibration proof mounting 5, pass from the adpting flange (following adpting flange 2) of the other end, guaranteed that lead does not expose in whole walking in the lineal travel.
The utility model is assembled by modes such as injecting glue and mechanical connections, wherein, with regard to the utility model, an outstanding feature is to be embodied on the injecting glue assembling mode, after each part is finished mechanicalness assembling, between end cap 3 and the neck flange, between vibration damping head 4 and the vibration proof mounting 5, all also exist between overcoat 7 and vibration damping head 4, the vibration proof mounting 5 certain radially or axial activity space; Behind inner injecting glue, these gaps will be filled by glue by the hole for injecting glue on the overcoat 7, thereby guarantee that the relative position between each movable members fixes.Simultaneously, because adopted silastic liquid, can realize to axial compression, axial tension, circumferentially reversing and the vibration damping of three kinds of compound actions, and not have the machinery wearing and tearing with certain elastic performance.
Parts such as above-mentioned adpting flange, end cap, vibration damping head, vibration proof mounting, overcoat are all selected for use high temperature resistant and are not had the material of magnetic, and such as the duralumin material, material not only gently but also comparatively firm and does not have magnetic.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is made amendment or is equal to replacement, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
