A positioning device for a dolly

Abstract

This utility model discloses a positioning device for a material cart, including a base plate and a material cart. The material cart is located on top of the base plate, and a limiting frame is fixedly connected to the top of the base plate. A limiting mechanism is provided at the bottom of the material cart, and a connecting mechanism is movably sleeved on the left side of the material cart. This utility model, by setting a limiting frame, can effectively position the parked material cart, solving the problems of existing material cart positioning methods that mainly rely on operator visual or experience to adjust the cart's position. These methods are easily affected by insufficient light, obstructed vision, etc., causing the material cart to deviate from the designated parking point, such as a shelf or loading / unloading point. Furthermore, uneven ground can easily lead to the risk of the cart slipping and colliding. This device achieves an auxiliary positioning effect.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, the positioning device for a material cart provided by this utility model includes a base plate 1 and a material cart 2. The material cart 2 is located on the top of the base plate 1. A limiting frame 3 is fixedly connected to the top of the base plate 1. A limiting mechanism 4 is provided at the bottom of the material cart 2. A connecting mechanism 5 is movably sleeved on the left side of the material cart 2.

[0020] refer to Figure 2 and Figure 3 The limiting mechanism 4 includes a fixed frame 41, a rubber plate 42 and a storage groove 43. The rubber plate 42 is fixedly installed on the top of the fixed frame 41, and the top of the rubber plate 42 is tightly fitted to the bottom of the material cart 2. The storage groove 43 is opened on the right side of the top of the base plate 1.

[0021] As a technical optimization of this utility model, by setting a limiting mechanism 4, the fixing frame 41 can fix and limit the rubber plate 42, the limiting plate can be used to press and limit the material cart 2, and the storage groove 43 can be used to facilitate the temporary storage of the fixed frame 41 that has not been moved.

[0022] refer to Figure 2 The connecting mechanism 5 includes a sleeve 51, with a first shaft 52 fixedly connected to both the front and rear sides of the sleeve 51. A connecting plate 53 is movably connected to the surface of the first shaft 52. A second shaft 54 ​​is fixedly connected to both the front and rear sides of the fixing bracket 41. The surface of the first shaft 52 is movably connected to the inner wall of the connecting plate 53.

[0023] As a technical optimization of this utility model, by setting a connecting mechanism 5, the connecting plate 53 is used to connect the first shaft 52, the sleeve 51, the second shaft 54 ​​and the fixing frame 41. The first shaft 52 and the second shaft 54 ​​facilitate the rotation of the connecting plate 53. The material cart 2 pushes the sleeve 51 to move, which can sequentially drive the first shaft 52, the connecting plate 53, the second shaft 54 ​​and the fixing frame 41 to move.

[0024] refer to Figure 1 The top of the front and rear sides of the limiting frame 3 is provided with a first slide rail 6. The inner wall of the first slide rail 6 is movably connected to the surface of the first shaft 52. The bottom of the front and rear sides of the limiting frame 3 is provided with a second slide rail 7. The inner wall of the second slide rail 7 is movably connected to the surface of the second shaft 54. The surfaces of the first shaft 52 and the second shaft 54 ​​away from the material cart 2 are fixedly connected with a limiting ring 8.

[0025] As a technical optimization of this utility model, by setting a first slide rail 6, a second slide rail 7 and a limiting ring 8, the first slide rail 6 can improve the stability of the movement of the first shaft 52 and play a limiting role, and the second slide rail 7 can improve the stability of the movement of the second shaft 54 ​​and play a limiting role.

[0026] refer to Figure 3 A fixing plate 9 is fixedly connected to the left side of the inner wall of the limiting frame 3. Two slots 10 are opened on the right side of the fixing plate 9. Two insert plates 11 are fixedly connected to the left side of the card sleeve 51. The insert plates 11 are inserted into the inside of the slots 10.

[0027] As a technical optimization of this utility model, by setting a fixing plate 9, a slot 10 and an insert plate 11, the slot 10 can enable the fixing plate 9 to limit the insert plate 11, the insertion plate 11 can limit the card sleeve 51, and the card sleeve 51 can limit the material cart 2.

[0028] refer to Figure 2 A slope plate 12 is fixedly connected to the right side of the base plate 1, and a door panel 13 is movably connected to the front and rear sides of the right side of the limiting frame 3 via hinges.

[0029] As a technical optimization of this utility model, by setting up a ramp 12 and a door panel 13, the ramp 12 facilitates the movement of the material cart 2 to the top of the base plate 1, and the door panel 13 is equipped with a door lock. After the material cart 2 enters the limit frame 3, the door panel 13 can be flipped to prevent the material cart 2 from slipping out.

[0030] The working principle and usage process of this utility model are as follows: When positioning the material cart 2, first open the door panel 13, then push the material cart 2 to the top of the bottom plate 1 via the ramp 12. When the protruding plate on the left side of the material cart 2 enters the sleeve 51 and continues to move to the left, it can sequentially drive the first shaft 52, the connecting plate 53, the second shaft 54, and the fixing frame 41 to move. At this time, the sleeve 51 drives the first shaft 52 to slide inside the first slide rail 6, and the fixing frame 41 drives the second shaft 54 ​​to slide inside the second slide rail 7. When the sleeve 51 moves horizontally to the left and drives the insert plate 11 to insert into the slot 10, the fixing frame 41 drives the rubber plate 42 to move to the bottom of the material cart 2, and makes the top of the rubber plate 42 fit tightly against the bottom of the material cart 2, thereby enabling the material cart 2 to be positioned upwards. Finally, flip the door panel 13 to cover the right side of the material cart 2 to prevent the material cart 2 from slipping to the right.

[0031] In summary, this material cart positioning device, by setting a limit frame 3, can effectively position the parked material cart 2, solving the problem that the existing material cart positioning methods mainly rely on the operator's visual or experience to adjust the position of the material cart, which is easily affected by factors such as insufficient light and obstructed vision, causing the material cart to deviate from the designated parking point, such as the shelf or loading and unloading point. At the same time, if the ground is uneven, there is a risk of the cart slipping and colliding.
