[0021] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following will further describe the solution of the present utility model. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1 to 3 as shown, this embodiment provides an anti-overturning device for a trolley, which includes a support 1 and an adjustment assembly 4.

[0024] Among them, referring to Figure 3 as shown, the top of the support 1 is connected to the bottom of the trolley 2. One side of the support 1 has a notch groove 101, and the notch groove 101 faces the guide rail 3 and is in clearance fit with the guide rail 3. The adjustment assembly 4 is arranged on the side of the support 1 facing the guide rail 3. The adjustment assembly 4 includes an adjustment member 401, an adjustment shaft 402, a bearing 403 and a bearing wheel 404 connected in sequence. Driving the adjustment member 401 drives the adjustment shaft 402 to move in the vertical direction, so as to drive the bearing wheel 404 to move in the vertical direction, realizing the fitting of the bearing wheel 404 with the guide rail 3, so as to slide along the guide rail 3. Specifically, the support 1 is used to be connected to the trolley 2 and is arranged at the bottom of the trolley 2, so that the notch groove 101 can be in clearance fit with the guide rail 3. When the trolley has a center-of-gravity shift, the contact surface between the notch groove 101 and the guide rail 3 is stably clamped, avoiding the side overturning of the whole device and the trolley 2. By arranging the adjustment assembly 4 on the side of the support 1 facing the guide rail 3, the height of the adjustment shaft 402 is changed by adjusting the adjustment member 401, so as to adjust the height of the bearing 403, so as to realize the adjustment of the use height of the bearing wheel 404, so that the bearing wheel 404 can be in contact with the guide rail 3, so that the bearing wheel 404 can move along the guide rail 3, realizing that the whole device and the trolley 2 can ensure stable sliding along the guide rail 3. This anti-overturning device for a trolley has a simple structure, can ensure that the trolley 2 maintains a state perpendicular to the guide rail 3, prevent side overturning, and improve safety.

[0025] Furthermore, referring to Figure 2 as shown, the number of supports 1 is the same as the number of wheels of the trolley 2, and the supports 1 are arranged at the positions corresponding to the wheels. Two supports 1 are symmetrically arranged, and the two notch grooves 101 on the two supports 1 face away from each other. Specifically, the supports 1 are arranged corresponding to the wheels of the trolley 2, that is, the supports 1 are arranged inside the guide rail 3, so that the notch grooves 101 face the inside of the guide rail 3 and are in clearance fit with the guide rail 3. The wheels are placed on the guide rail 3 to realize the movement of the trolley. The supports 1 are arranged in this way, so that when the trolley 2 has a center-of-gravity shift, the notch groove 101 can be clamped with the inside of the guide rail 3, thereby avoiding the side overturning of the trolley 2.

[0026] To further ensure the anti-overturning effect of this device, the support 1 is formed by welding steel plates, and the steel plates have a certain thickness, and the specific thickness is 15 to 20 mm.

[0027] Continue to refer to Figure 2 As shown, it further includes a through cover 5 and a blind cover. The through cover 5 and the blind cover are respectively arranged on both sides of the bearing 403, and are both connected to the bearing 403 by bolts. Specifically, the through cover 5 and the blind cover are respectively arranged on both sides of the bearing 403 to protect the bearing wheel 404.

[0028] Continue to refer to Figure 2 As shown, a felt ring 7 is arranged between the through cover 5 and the adjusting shaft 402, and a retaining ring 8 is arranged at the bottom of the adjusting shaft 402. The felt ring 7 is arranged on the outer periphery of the adjusting shaft 402 to prevent lubricating oil from leaking out and foreign impurities, dust, etc. from invading the bearing 403, so as to prevent damage to the bearing 403 and the bearing wheel 404, thereby improving the service life of the bearing 403 and the bearing wheel 404 and the overall service life of the device. The retaining ring 8 is arranged at the bottom of the adjusting shaft 402 to prevent the bearing 403 from axially moving.

[0029] Refer to Figure 3 As shown, a plurality of threaded holes are provided at the top of the support 1, and bolts pass through the threaded holes to connect with the trolley 2, ensuring the stable connection between the support 1 and the trolley 2.
