Abstract
Description
Technical Field
[0001] The utility model discloses a detachable and quick-change wheel rim locking ring, belonging to the field of wheel rim accessories. Background Art
[0002] Automobile tire components all include tires and rims for mounting tires. The existing rim structure generally has a rim at the edge of the rim body, and at least one side of the rim is locked by a locking ring. The existing locking ring is usually made of annular elastic steel, and the annular steel has a fracture that can be elastically opened when the locking ring is mounted on the rim to facilitate the locking ring to be clamped and fixed on the rim body. This traditional locking ring structure can well realize the installation of the tire. When the tire needs to be replaced, the locking ring is elastically expanded by a special short-time expansion device, and the locking ring can be removed from the rim body.
[0003] However, some heavy-duty trucks generally have double-row tires arranged side by side. When replacing the tires, it is generally necessary to remove the outer tire first and then remove the locking ring of the inner tire. The disassembly is very troublesome, labor-intensive and time-consuming. In order to facilitate the replacement of the tires, the prior art also adopts a structure in which locking rings are arranged on both sides of the rim. Such a structure does not require the removal of the outer rim, but during the removal process, the locking ring on one side is easy to remove, but the locking ring on the other side must be expanded to pass through the entire rim body due to the large width to be crossed, and the operating space is very small. The existing short-time expansion device can only be operated for a short time and cannot be moved for a long distance. Therefore, it is difficult to remove the inner locking ring, which makes disassembly difficult and easily causes the elastic failure of the locking ring, increasing safety hazards, thereby causing great inconvenience to tire replacement. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a detachable quick-change wheel rim lock ring.
[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A disassembly quick-change wheel rim lock ring comprises two half-circle bodies, which are butt-jointed together to form a circular ring structure, and the butt ends of the two half-circle bodies are each provided with a butt joint, and the two butt joints are butt-jointed together, and a connecting block is provided on the two butt joints, and a plurality of locking blocks are provided at the bottom of the connecting block, and the locking blocks penetrate into the two butt joints to lock and connect the two butt joints, and the ends of the connecting block are connected and fixed to the outer surfaces of the two butt joints by fasteners.
[0007] Further, the docking member includes a docking block fixed to the end of the semi-circular body. A number of insertion slots and insertion blocks are equidistantly arranged on the side of the docking block, and the insertion slots and the insertion blocks are arranged alternately. The insertion slots and the insertion blocks on the two docking blocks are inserted into each other.
[0008] Further, the docking member further includes a first through-hole opened at the top of the insertion slot and a second through-hole opened on the insertion block. The first through-hole penetrates to the outer surface of the docking block, and the first through-hole is adapted to the second through-hole.
[0009] Further, the locking block passes through the first through-hole into the second through-hole to connect the insertion block and the insertion slot together.
[0010] Further, the docking block is an arc-shaped L-shaped structure, and the docking block and the semi-circular body are an integral structure.
[0011] Further, the cross-sectional shape of the inner side of the semi-circular body is adapted to the groove on the side of the rim body.
[0012] Further, elastic filling blocks are provided at the docking ends of the two semi-circular bodies. When the two semi-circular bodies are docked, the two elastic filling blocks are elastically squeezed together to fill the gap between the semi-circular bodies.
[0013] Advantages of the present utility model:
[0014] Through the arrangement of the insertion slots and the insertion blocks, the rapid docking ability between the two docking blocks is improved, the assembly efficiency is improved, and the contact area is increased.
[0015] Through the arrangement of the first through-hole, the second through-hole and the fastener, the contact area between the two docking blocks is increased, and at the same time, the purpose of locking the two docking blocks is achieved, so that the two docking blocks will not fall off randomly, and the locking ability between the two docking blocks is strengthened.
