DETAILED DESCRIPTION

[0021] Example, by Figure 1-6 The utility model includes a rail 1, a wheel block 2 is installed on the top of the rail 1, and a wedge block 4 is integrally connected to one side of the wheel block 2. A limiting sleeve 5 is slidably connected to the rail 1, and a wedge groove 6 is provided on one side of the limiting sleeve 5. The wedge block 4 is located on one side of the limiting sleeve 5 and extends into the inside of the wedge groove 6. An L-shaped side plate 3 is fixedly connected to the front and rear sides of the rail 1 respectively. The limiting sleeve 5 is located between the two L-shaped side plates 3. A receiving groove 8 is provided on one side of the wedge block 4, and a receiving cavity 10 is provided on the inner wall of the receiving groove 8. The receiving groove 8 and the receiving cavity A nut 9 is fixedly embedded at the connection point 10, and an operating rod 11 is installed inside the storage cavity 10. The operating rod 11 passes through the storage groove 8 and the limit sleeve 5 and extends to the other side of the limit sleeve 5. A sleeve 13 is provided on the outer end of the operating rod 11, and a first impact block 14 and a second impact block 15 are fixedly connected to the outer end of the sleeve 13. The first impact block 14 is located inside the storage groove 8, and the second impact block 15 is located on the other side of the limit sleeve 5. A handle 16 is fixedly connected to the top of the sleeve 13, and the handle 16 is located on the side of the second impact block 15 away from the first impact block 14.

[0022] The limiting sleeve 5 is composed of two symmetrically arranged half-clamping blocks, the tops of the two half-clamping blocks are movably connected by a hinge, an opening 7 is opened on the other side of the limiting sleeve 5, the sleeve 13 passes through the opening 7, the limiting sleeve 5 is divided into two half-clamping blocks, and the wedge-shaped groove 6 and the opening 7 on the limiting sleeve 5 are also symmetrically divided into two parts, which makes it convenient to remove or install the limiting sleeve 5 from the rail 1, and also convenient to remove the limiting sleeve 5 from the sleeve 13 passing through the opening 7.

[0023] The end of the operating rod 11 extending out of the limit sleeve 5 is fixedly connected to the rotating wheel 12, and the outer surface of the end of the operating rod 11 located inside the storage chamber 10 is processed with a thread. The operating rod 11 passes through the nut 9, and the operating rod can be pushed, pulled and rotated by the rotating wheel 12, and the thread of the operating rod 11 is screwed together with the nut 9. At this time, the position of the operating rod 11 is fixed, and the operating rod 11 also extends outward for a section, which facilitates the movement of the sleeve 13 along the operating rod 11, so as to bring the first impact block 14 or the second impact block 15 to impact the limit sleeve 5, thereby realizing the disassembly and installation of the limit sleeve 5.

[0024] Working principle:

[0025] The wheel block 2 is placed on the rail 1 and blocks the wheel with its arc surface. First, the operating rod 11 is partially stretched out from the receiving groove 8 and the receiving cavity 10 so that the threaded portion of the operating rod 11 is threadedly connected with the nut 9. Then the limiting sleeve 5 is put on the rail 1. At this time, the sleeve 13 on the operating rod 11 just passes through the opening 7. Move the limiting sleeve 5 so that it is gradually put on the wedge block 4. At this time, the limiting sleeve 5 is located between the two L-shaped side plates 3 and will not separate anymore. Then hold the handle 16 and push the sleeve 13 toward the limiting sleeve 5. The second impact block 15 is moved in the direction of rotation, during which the sleeve 13 will bring the second impact block 15 to impact the limiting sleeve 5, and the limiting sleeve 5 will be gradually reinforced and sleeved on the wedge block 4 after the impact, until the wheel blocking block 2, the wedge block 4 and the limiting sleeve 5 are all fixed to the rail 1 by the mortise and tenon joints and cannot move, thereby achieving the purpose of the wheel blocking block 2 blocking the wheel. After the installation is completed, hold the running wheel 12 and turn the operating rod 11. After the threaded connection between the operating rod 11 and the nut 9 is released, push the operating rod 11 again to insert it into the storage cavity 10 as much as possible to achieve the storage function;

[0026] When it is necessary to remove, repeat the above operation again to pull out the operating rod 11 and screw it on the nut 9, then hold the handle 16 to pull the sleeve 13 away from the limiting sleeve 5. During this period, the sleeve 13 will carry the first impact block 14 to hit the inner wall of the wedge-shaped groove 6, and then the limiting sleeve 5 will be loosened and no longer mortise and tenoned on the wedge block 4. At this time, the limiting sleeve 5 can be manually removed, and the wheel block 2 can also be removed from the rail 1.
