Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer The accompanying drawing of type embodiment, the technical scheme of the utility model embodiment is clearly and completely described.Obviously, it is described Embodiment is part of the embodiment of the present utility model, rather than whole embodiments.Based on described of the present utility model Embodiment, the every other embodiment that those of ordinary skill in the art are obtained, belong to the scope that the utility model is protected.

The utility model is present applicant based on the fact that and the innovation and creation made by discovery.

The gasket construction of conventional gaskets is annular uniform thickness, and its contact with hinge contacts for face, as shown in figure 3, axle Hold and conventional gaskets are arranged with 30, wherein the two sides of pad 40 of conventional gaskets are the plane of uniform thickness, that is to say, that hinge 10 contact with the pad 40 of conventional gaskets for face.Because face contact has larger friction for hinge and conventional gaskets Power, this substantially reduces the service life of hinge.

Based on this, present inventor draws following innovation and creation by studying for a long period of time and finding.

The packing ring 20 according to the utility model embodiment is specifically described below in conjunction with the accompanying drawings.

As shown in Fig. 2 body 21 and pad 22 are included according to the packing ring 20 of the utility model embodiment.

Specifically, as shown in Figure 1, Figure 2 and Figure 4, packing ring 20 is used to be arranged on hinge 10, and body 21, which is provided with, to be run through Body 21 is used to install the mounting hole 211 of bearing 30, pad 22 be located at the periphery of body 21 and with the periphery wall phase of body 21 Even, at least side wall of pad 22 be provided with it is multiple along its it is circumferentially-spaced open arrangement and with 10 points of projections 221 contacted of hinge.

That is, body 21 is provided with mounting hole 211, mounting hole 211 is used for through bearing 30, so as to realize packing ring 20 With 10 axial-rotations of hinge.The outer wall of body 21 stretches out to form a pad 22 contacted with hinge 10, the week of pad 22 Multiple raised 221 are provided with upwards, by the setting of projection 221, packing ring 20 is contacted with hinge at 10 points, and then reduce packing ring Frictional force between 20 and hinge 10.

Thus, according to the packing ring 20 of the utility model embodiment, to be formed by stretching out in the periphery wall to body 21 Pad 22 on and at least one side is provided with projection 221, and projection is 221 circumferentially disposed so that projection 221 is formed with hinge 10 Point contact.When hinge 10 is during rotation, it is possible to reduce the friction between packing ring 20 and hinge 10, and then extend hinge 10 Service life, it is cost-effective.

According to one embodiment of the present utility model, as shown in figure 4, the two side walls of pad 22 are respectively equipped with projection 221.

In other words, projection 221, two walls for making hinge 10 be contacted with pad 22 are equipped with the two side walls of pad 22 It is a contact on face, reduce further the frictional force between packing ring 20 and hinge 10.

In some embodiments of the present utility model, projection 221 is hemisphere.Because hemispheroidal surface is arc Shape, and arc contacts more smooth, the further frictional force reduced between hinge 10 and packing ring 20 with the side surface of hinge 10.

Preferably, the projection 221 in the two side walls of pad 22 is symmetrical arranged relative to pad 22.

That is, projection 221 is symmetrical for axis formation minute surface with pad 22 on the two side of pad 22, so padding When being rotated between circle 20 and hinge 10, the stress equalization at the both ends of packing ring 20, it will not deflect and influence the stationarity of rotation.

Further, multiple raised 221 it is uniformly distributed along circumferentially-spaced open of pad 22.Further make whole packing ring 20 by Power is balanced, keeps having stable dynamic balancing between packing ring 20 and hinge 10.

Preferably, body 21 is column, and mounting hole 211 is manhole.Circular through hole is more beneficial for the week of bearing 30 To rotation, make hinge rotation more smooth.

According to some embodiments of the utility model, at least a portion of the outline in the section of body 21 is formed as not advising Then arc.

That is, the outer surface of body 21 has irregular arc, shape during in order to change 10 circumferential movement of hinge Into irregular track, to adapt to demand during handrail rotation, can also be designed in certain other embodiment of the present utility model Into circular or different shape to adapt to the demand in actual use.

Preferably, packing ring 20 is integrated moulding.Because example structure of the present utility model is simple, it is more prone to one Injection molding, and integrated injection molding part can avoid connecting deviation, influence the quality of packing ring 20.

In preferred embodiment of the present utility model, packing ring 20 is POM (polyformaldehyde) material pieces.Because POM materials have Extraordinary anti-wear performance and high-temperature stability, therefore can preferably increase the service life of packing ring 20.

Sum it up, as shown in Figure 3 and Figure 4, by being circumferentially with multiple projections on the pad 22 of the periphery of body 21 221 so that projection 221 forms point with hinge 10 and contacted, can be significantly with conventional gaskets compared with the face contact that hinge 10 is formed The friction reduced between packing ring 20 and hinge 10, and then extend the service life of hinge 10 and packing ring 20, it is cost-effective, and have The handrail or other devices of the structure of packing ring 20 can possess more preferable performance.

Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement The scope of protection of the utility model is also should be regarded as with retouching.
