Description

Explosion-proof rubber mat

Technical Field

The utility model belongs to the technical field of the automobile parts and specifically relates to an explosion-proof cushion.

Background

At present, metal explosion-proof gaskets are generally installed on automobile cushion tires, metal materials are mostly Fe/Ep.Zn18.C, the hardness of the metal gaskets is greatly different from that of rubber materials, the metal gaskets are assembled on an automobile with an inner tire, an outer tire and a rim, the metal gaskets deform under stress in the driving process, or the cushion tires and the inner tire are easily cut under the condition that the length of the metal gaskets is unreasonable in design, so that the air pressure of the tires is reduced, and further safety accidents are caused.

At present, metal gaskets do not have corresponding national standards, standards formulated by different automobile host manufacturers are not uniform, metal gaskets with different sizes have the phenomenon of mismatching with the structural design of a rim in the assembling process, particularly, the metal gaskets without positioning grooves cannot effectively fix the positions of the gaskets, and under the action of internal pressure, a cushion tire and an inner tire are outwards protruded from a rim inflating valve positioning hole, so that the problem of cracking of the cushion tire is easily caused, and the safety performance of an automobile is threatened.

Disclosure of Invention

The utility model discloses just for solve above-mentioned background art's problem, provide a simple structure, safe in utilization, can adapt to the rim of different specifications and the explosion-proof cushion who fills up the child.

Therefore, the utility model provides an explosion-proof cushion, it is equipped with the cushion body, and the cushion body is equipped with two parts, and a part is the bow, be equipped with the circular recess in the middle of the bow, be equipped with the through-hole that can make the inflating valve pole pass in the middle of the circular recess, another part of cushion body is the cylinder, bow and cylinder formula structure as an organic whole, and the back of cushion body still is equipped with positioning groove, and positioning groove is column structure, and its bottom and circular recess communicate with each other.

Preferably, the thickness of the edges of the bow transitions from the center to the two sides.

Preferably, the junction of bow-shaped body and cylinder is equipped with the dislocation groove, locates the back of cushion body.

Preferably, the cylinder is a triangular prism or a square.

Preferably, the rubber mat body is made of rubber.

The utility model has the advantages that:

(1) the utility model has simple structure, convenient installation and safe use, is provided with the rubber pad body, the rubber pad body is divided into a bow-shaped body and a triangular prism body or a square body, the edge thickness of the bow-shaped body is transited from the center to the edge part, and the damage to the inflating valve caused by internal pressure can be effectively avoided; the middle of the valve rod is provided with a circular groove, and a through hole is arranged in the circular groove and plays a role in fixing the valve rod. The back design of cushion body has the columnar positioning groove, can insert in the inflating valve constant head tank of rim, prevents to take place the displacement, is fixed in the explosion-proof cushion on the child pad effectively.

(2) The utility model discloses a length can change according to the change of rim specification, has improved the matching degree.

(3) The utility model discloses a material is rubber, on the one hand, has good elasticity, and the relative ratio is in metal gasket, can prevent to take place because the gasket installation is not in place and punctures the condition of filling up the child, has improved the security performance of car. On the other hand, the water-saving agent can be repeatedly used, and plays a good role in saving resources and protecting the environment.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention and are not limited to the present invention.

Example 1

The utility model provides an explosion-proof cushion, as shown in figure 1, it is equipped with cushion body 1, and cushion body 1 is equipped with two parts, and partly be bow-shaped body 2, and its edge thickness has the transition to both sides from the center, can avoid effectively because of the damage that interior pressure caused to the inflating valve. The design is bow-shaped body 2, and the edge is arc-shaped, so that the damage of corners to the cushion tire can be effectively avoided. As shown in fig. 2, the bow 2 has a circular groove 3 in the middle, and a through hole 4 for passing a valve stem is formed in the middle of the circular groove 3 for connecting and fixing the valve. The other part of cushion body 1 is triangular prism 7, bow 2 and triangular prism 7 formula structure as an organic whole, and the design is in order to make the better laminating of explosion-proof cushion on filling up the child like this, plays the fixed action, prevents its landing. The junction of bow-shaped body 2 and triangular prism 7 is equipped with dislocation groove 6, is located the back of cushion body for match with the crease department of pad child, make explosion-proof cushion can laminate in pad child more.

As shown in fig. 3, the back of the rubber mat body 1 is further provided with a positioning groove 5, the positioning groove 5 is of a columnar structure, and the bottom end of the positioning groove 5 is communicated with the circular groove 3. The positioning groove 5 is used for being clamped with a rim valve slot to play a role in fixing and positioning so as to prevent the explosion-proof rubber mat from displacing.

The length of the explosion-proof rubber mat can be changed according to the change of the specification of the rim, and the matching degree of the explosion-proof rubber mat is improved.

The explosion-proof rubber mat is made of rubber, has good elasticity on one hand, and can prevent the cushion tire from being punctured due to the fact that the gasket is not installed in place compared with a metal gasket, and the safety performance of the automobile is improved. On the other hand, the water-saving agent can be repeatedly used, and plays a good role in saving resources and protecting the environment.

Example 2

As shown in fig. 4, the rubber mat body 1 is divided into two parts, one part is the bow-shaped body 2 which is the same as that of the embodiment 1, and the other part is the square body 8, so that the rubber mat body can adapt to padding tires with different specifications, the rubber mat body is more attached to the padding tires, and the stability is improved. Other features are the same as those of embodiment 1, and will not be described in more detail here.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
