Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. mentioned in the following embodiments are directions with reference to the drawings only, and thus, the directional terms used are intended to illustrate rather than limit the inventive concept.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example (b): a test rim for a tire, see figures 1 and 2, comprises a main body 1 in a disc-shaped arrangement, a spoke piece 2 arranged around the main body 1 and two shoulder parts 3 arranged around the spoke piece 2. Of the two shoulders 3, at least one shoulder 3 can slide on the spoke piece 2 along the axial direction of the main body 1.

When aerifing the tire of high flat ratio specification, through the slip to shoulder 3, reduce the distance between two shoulders 3, thereby make two tire beads of tire can laminate respectively on two shoulders 3, then aerify the tire, because two tire beads laminate on two shoulders 3, thereby can not leak gas when making aerify, along with aerifing going on, two tire beads keep away from under the effect of atmospheric pressure gradually, and promote shoulder 3 simultaneously and slide in order to enlarge the distance between two shoulders 3, make two tire beads laminate two shoulders 3 all the time in the middle of the inflation process, accomplish until aerifing.

In particular, both shoulders 3 are provided to be able to slide on the spoke piece 2 in the axial direction of the main body 1.

Specifically, the outside of the spoke piece 2 is provided with the spout 21 that encircles the setting of spoke piece 2, and spout 21 is provided with two, and two spouts 21 correspond two shoulders 3 respectively, and the inboard of two shoulders 3 is two fixedly connected with slip rings 31 respectively, and two slip rings 31 divide and imbed in the middle of two spouts 21 and can slide along the axis direction of main part 1 in the middle of the spout 21. The radial plate block 2, the main body 1, the sliding groove 21, the shoulder 3 and the sliding ring 31 are coaxially arranged.

Specifically, one side that two spouts 21 kept away from each other is provided with two and keeps off ring 4, and two keep off ring 4 and the common enclosure of spoke plate piece 2 and form two spouts 21, set up two and keep off ring 4 and can dismantle the connection on spoke plate piece 2, through keeping off the setting of ring 4, conveniently install two slip rings 31 in the middle of two spouts 21.

Specifically, two sealing rings are fixedly connected to one side, away from each other, of each sliding ring 31, when the tire is inflated, the two sealing rings on the two sliding rings 31 respectively abut against the two retaining rings 4, and gas in the tire is not easy to leak from the contact position of the sliding ring 31 and the retaining ring 4 through the sealing rings, so that the tire is not required to be inflated all the time.

Specifically, an annular sealing gasket is arranged at the joint of the baffle ring 4 and the spoke plate block 2, and through the arrangement of the annular sealing gasket, gas is not easy to leak from the joint of the baffle ring 4 and the spoke plate block 2.

Specifically, the baffle ring 4 and the spoke plate block 2 are detachably connected together through a plurality of bolts.

The working principle of the test rim for the tire in use is as follows: when aerifing the tire of high flat ratio specification, through the slip to shoulder 3, reduce the distance between two shoulders 3, thereby make two tire beads of tire can laminate respectively on two shoulders 3, then aerify the tire, because two tire beads laminate on two shoulders 3, thereby can not leak gas when making aerify, along with aerifing going on, two tire beads keep away from under the effect of atmospheric pressure gradually, and promote shoulder 3 simultaneously and slide in order to enlarge the distance between two shoulders 3, make two tire beads laminate two shoulders 3 all the time in the middle of the inflation process, accomplish until aerifing.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
