Referring to fig. 1 to 4, an embodiment of the present utility model provides a tire pull code, which includes: the code pulling seat 1 is provided with a threaded hole 11; a top connector 2, wherein the top connector 2 comprises a threaded part 21, and the threaded part 21 is screwed with the threaded hole 11; at least two pull claw pieces 3, pull claw pieces 3 are connected to the pull code seat 1, pull claw pieces 3 comprise hook claw portions 31, and the hook claw portions 31 are located on the same side of the pull code seat 1.

In this embodiment, the threaded portion 21 is provided with an external thread, the threaded hole 11 is provided with an internal thread matching with the threaded portion 21, and the threaded portion 21 is connected to the threaded hole 11, so that the top connector 2 is screwed with the code pulling seat 1, and when the top connector 2 and the code pulling seat 1 rotate relatively, the code pulling seat 1 will perform translational movement on the threaded portion 21. In actual operation, the propping piece 2 is propped against the spindle nose of the tire to be disassembled, the pull claw piece 3 is buckled and hung on the inner side of the steel ring of the tire to be disassembled, and the pulling code seat 1 cannot rotate at the moment, so that the propping piece 2 and the pulling code seat 1 can rotate relatively by rotating the propping piece 2, the propping piece 2 rotates inwards, the pulling code seat 1 moves towards one side far away from the spindle nose, the pulling code seat 1 drives the pull claw piece 3 to move together, and the pull claw piece 3 pulls the steel ring to move together, so that the separation of the steel ring and the spindle nose is completed, and the disassembly of the tire is completed.

As a preferable technical scheme of the utility model, the pull claw pieces 3 are uniformly distributed on the pull code seat 1 by taking the top connection piece 2 as the circle center, namely, the pull claw pieces 3 are uniformly distributed on the circumference by taking the top connection piece 2 as the circle center, so that when the pull claw pieces 3 apply tension to the steel ring, the acting force of the pull claw pieces 3 can be more uniformly distributed on the inner side of the steel ring.

Alternatively, the number of the pull claw members 3 is two.

Further, the code pulling seat 1 is in a bar shape, the top connecting piece 2 is arranged at the central point of the code pulling seat 1, and the pull claw pieces 3 are symmetrically arranged at two ends of the code pulling seat 1.

Referring to fig. 1 to 3 and fig. 6, specifically, the pull claw member 3 is movably connected with the pull code base 1.

Further, the pull code seat 1 is provided with a connecting hole 12, the pull claw piece 3 movably penetrates through the connecting hole 12, and the pull claw piece 3 can move in the connecting hole 12 along the opening direction of the connecting hole 12.

Further, a blocking member 32 is provided at an end of the pull claw member 3 away from the hooking portion 31, and an area of the blocking member 32 is larger than an area of the connection hole 12. It should be explained that the pull claw member 3 is disposed through the pull code seat 1, the hook portion 31 and the blocking member 32 are respectively disposed at two sides of the pull code seat 1, so that when the pull code seat 1 moves in a direction away from the hook portion 31, the blocking member 32 drives the pull claw member 3 to move together, and alternatively, the blocking member 32 may be a plate member sleeved on the outer side of the pull claw member 3, or may be an integral structure with the pull claw member 3, and extend outwards from the pull claw member 3.

In this embodiment, the pull claw member 3 is movably connected with the pull code seat 1, when the pull claw member 3 is damaged or deformed, the pull claw member 3 can be detached and replaced with a new pull claw member 3, and it should be mentioned that the pull claw member 3 can rotate in the through hole, so before the hook claw 31 is inserted into the steel ring, the hook claw 31 can be smoothly inserted into the steel ring by rotating and adjusting the orientation of the hook claw 31, and further, in the actual setting, the aperture of the through hole is larger than the diameter of the pull claw member 3, so that the pull claw member 3 can axially swing at a certain angle in the through hole, and the hook claw 31 can be inserted into the steel ring more smoothly.

Referring to fig. 4 and 5, as a preferred technical solution of the present utility model, the tire puller further includes a spindle nose pad 4, the top connector 2 further includes a top connection portion 22 disposed on one side of the threaded portion 21, the top connection portion 22 and the hook portion 31 are disposed on the same side of the puller seat 1, and the spindle nose pad 4 is disposed on the top connection portion 22. In this embodiment, the axle head backing plate 4 is used for directly contacting with the axle head, and the purpose of setting the axle head backing plate 4 is to avoid the damage of the top connection part 22 directly abutting against the axle head to the axle head, and the axle head backing plate 4 is set on the top connection part 22 to enlarge the abutting contact area with the axle head, so that the acting force of the top connection part 2 after the contact area is enlarged can be uniformly distributed on the axle head, and the damage to the axle head is avoided.

Further, a first groove 41 is formed in the shaft head base plate 4 towards the side close to the top connection portion 22, and the top connection portion 22 extends into the first groove 41 to be abutted to the bottom of the first groove 41. It should be noted that the first groove 41 is used to provide a positioning function for the top connection portion 22, so as to prevent the top connection portion 22 from sliding and deviating on the gudgeon pad 4, while the top connection portion 22 can still rotate relative to the first groove 41, so that when the top connection member 2 rotates, the top connection portion 22 rotates relative to the first groove 41, and the gudgeon pad 4 and the gudgeon remain relatively stationary.

Further, the second groove 42 is arranged on the side, far away from the top connection portion 22, of the shaft head base plate 4, the second groove 42 faces the shaft head, and in the working process, the shaft head is located in the second groove 42, so that a positioning effect can be achieved, and sliding offset between the shaft head base plate 4 and the shaft head is avoided.

While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
