Abstract

The utility model relates to a split connecting piece of an armor chain of a tyre, which is used for the structural improvement of the antiskid of vehicle tyres and the protection of the armor chain. The middle of a shackle which is used as a connecting piece is provided with a pin, and the pin is a cylinder elastic pin; the outer side of the pin is provided with a bushing; two surfaces of the bushing, which correspond to the inner walls of a shackle body, are provided with two concave surfaces; the radian of the concave surfaces corresponds to the radian of the inner walls of the shackle body; the spacing of other two side surfaces of the bushing correspond to the thickness of the shackle body; shoulders of the bushing and opening ends of the shackle body are in lap joint. Because the outer side of the pin of the shackle body is provided with the bushing, the shoulders of the bushing and the two opening end parts are in the lap joint, the damages of the opening end parts of the shackle body can be avoided. The utility model has the characteristics of reasonable structure, reliable connection, difficult damages for the shackle body, etc. The utility model is especially suitable for the connection of the head and the tail of the armor chain protected by the tyres and the connection of side chains.

Description

The attaching parts of the armoring chain of split type tire

Technical field

The utility model relates to a kind of motor vehicle tire fender guard, especially relates to the improvement that armoring chain structure was slided, protected to a kind of guarantor who is used for the mine vehicle tyre.

Background technology

The tire of various vehicles; especially the tire of the heavy-duty vehicle that uses in building sites such as mine, building operation; since directly contact with sharp-pointed rock mass such as ore, its wear on tyres and well damage, and this has just caused with armoring chain protects tire to reduce wear, to save production cost.The attaching parts of the tire protection chain of prior art adopts open shackle, and the middle pin that adopts separates, and forms the space of two semi open models, so that each space holds an annulus, plays interconnect function by this.This kind shackle is simple in structure, but exists insufficient strength, defectives such as the easy clashing and breaking of pin, and the angle, two ends of particularly unloading button is pressure break very easily, thereby influences construction operation.

Summary of the invention

The utility model mainly is that the attaching parts that solves the existing in prior technology apparatus for protecting tyres-unload buckle structure is reasonable inadequately, and easy clashing and breaking of pin and open end be the deficiency of pressure break very easily.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: there is pin the centre as the shackle of attaching parts, and pin is a circular cylinder elastic cotter, and there is cushion cover the pin outside.

As preferably, it is a concave surface with unloading cooresponding two faces of button inwall for cushion cover, and the concave surface radian adapts with the radian that unloads the button inwall, cushion cover two side spacings are consistent with the thickness that unloads button in addition, the cushion cover shoulder overlaps with the open end that unloads button.

The utility model is owing to be provided with cushion cover in the pin outside of unloading button; its cushion cover shoulder with unload button two open end heads overlap joints; avoid unloading the pressure break of button open end head; have rational in infrastructure; connect reliable; both protected resilient pin, and can make again and unload button open end head characteristics such as the stressed strong point are all arranged.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.Shown in Figure 1, its shackle 1 is mainly used in side chain and connects and be connected from beginning to end, and 2 is annulus, and 3 is the chain piece; Fig. 2-6 is depicted as shackle, it unloads button 6 and is the open type ring, cushion cover 5 is enclosed within the outside of circular cylinder elastic cotter 4, cushion cover 5 is a concave surface 7 with unloading cooresponding two faces of button 6 inwalls, the concave surface radian adapts with the radian that unloads button 6 inwalls, two side spacings in addition of cushion cover 5 are slightly less than the opening that unloads button 6, the shoulder of cushion cover 5 and the open end overlap joint that unloads button 6.The utility model is owing to be provided with cushion cover 5 in pin 4 outsides of unloading button 6; its cushion cover shoulder with unload button two open end heads overlap joints; avoid unloading the damage of button 6 open end heads and circular cylinder elastic cotter 4; play the protective effect to shackle 1, the head and the tail that are specially adapted to the armoring chain of tire protection connect and are connected with side chain.

Claims
