[0016] The present utility model will be further described below with reference to the accompanying drawings.

[0017] As Figures 1 to 3 shown, the locking wheel stopper includes a wheel stopper body 2 and a locking device. The locking device includes a screw 3. One end of the screw 3 is provided with an external thread for sleeving a nut 5. The tail end of the screw 3 is bent downward to form a clamping rod 10 for clamping the other side of the rail 1; A retaining ring 9 is fixedly connected to the screw 3 in the horizontal direction near the clamping rod 10, that is, a retaining ring 9 is fixedly connected at the connection of the clamping rod 10 and the horizontal screw 3. A spring 8 is also sleeved on the screw 3, and the spring 8 is close to the retaining ring 9; The wheel stopper body 2 includes a clamping plate 13 for clamping with the rail 1, a flat plate fitting the upper surface of the rail 1, and a baffle 7 vertically fixedly connected to the flat plate. To make the baffle 7 more firm, a support plate 11 is fixedly connected to one side surface of the baffle 7, and the support plate 11 is perpendicularly connected to the baffle 7. The support plate 11 is in the shape of a right triangle. Two through holes are also provided on the baffle 7, and the through holes are located on both sides of the support plate 11. A sleeve 4 is fixedly connected to one side of each through hole. The upper surface of the sleeve 4 is provided with a through screw hole for inserting a guiding screw 6; The cross-section of the sleeve 4 matches the cross-section of the screw 3 in the horizontal direction.

[0018] The screw rod 3 is inserted into the sleeve 4. A section of groove 12 is provided on the upper surface of the screw rod 3 in the horizontal direction. The width of the groove 12 is matched with the screw hole. After the guiding screw 6 is inserted into the screw hole, the guiding screw 6 can move relative to the groove 12 on the screw rod 3. During the fastening process, the guiding screw 6 can prevent the screw rod 3 from rotating.

[0019] The support plate 11 is opposite to the sleeve 4 and is located on both side surfaces of the baffle 7 respectively.

[0020] The screw rod 3 is inserted through the through hole and passes through the sleeve 4. The sleeve 4 plays a role in strengthening the screw rod 3.

[0021] During operation, two screw rods 3 are required for fixation, which increases the firmness of fixation.

[0022] The working process of the present utility model: Place the wheel stopper body 2 on the rail 1. Springs 8 are respectively sleeved on the two screw rods 3. The springs 8 will not move downward along the screw rods 3 under the obstruction of the retaining rings 9, and play a buffering role for the wheel stopper body 2 and the screw rods 3. Then insert the screw rods 3 into the sleeves 4, so that the clamping rods 10 clamp the edge of the rail 1, and put in the guiding screws 6 to prevent the screw rods 3 from rotating. Screw nuts 5 on the external threads of the screw rods 3 for reinforcement. During the working process, only two nuts 5 need to be tightened to fix the wheel stopper body 2. When the work is finished, loosen the nuts 5, and the screw rods 3 will automatically reset under the elastic force of the springs 8, which is convenient for collection. The clamping plates 13 of the wheel stopper body 2 and the clamping rods 10 of the screw rods 3 are both in contact with the rail 1, so that the contact surface is larger, increasing the friction force and having a better fastening effect. Two screw rods 3 are used for fixation. When one screw rod 3 fails, the other screw rod 3 continues to bear the force, providing double insurance. High-strength materials are used, which can withstand greater forces and are not easily deformed.
