Description

Technical Field

[0001] This utility model belongs to the field of material transportation technology, specifically relating to an automatic positioning device for a Pack trolley. Background Technology

[0002] Material handling pack carts are commonly used to move various types of materials, especially in warehouses, factories, or logistics centers. These carts are designed primarily to carry and transport heavy or bulky items, ensuring efficient and convenient transport of materials from one location to another. When moving materials, the pack cart typically places them on a pallet on top of the cart. To ensure stability during transport, the pallet needs to be positioned on top of the cart to prevent it from shifting or tilting.

[0003] Traditional pallet positioning methods often use pins and screws for installation. These pins and screws require manual installation and removal by workers, which consumes installation time during material handling. This results in unnecessary time waste in an efficient production environment, reducing overall production efficiency. In addition, existing trolleys can only position and install pallets of fixed sizes, limiting their applicability. When positioning pallets of different sizes is required, they cannot be flexibly handled, further reducing overall production or logistics efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic positioning device for a Pack trolley, which can automatically position the pallet on the top of the trolley, reducing the need for manual operation, improving operational efficiency, reducing error rate, and also applicable to positioning pallets of different sizes, suitable for various types of cargo transportation and storage needs.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An automatic positioning device for a Pack cart includes a cart body and a tray. The tray is disposed on the top of the cart body, and an automatic positioning mechanism is disposed on the top of the cart body. The automatic positioning mechanism includes a positioning frame, a vertical plate, a connecting column, a positioning component, a compression spring, and a snap-fit ​​component. A plurality of positioning frames are installed on the top of the cart body. The vertical plates are respectively fixedly connected to the rear side of the positioning frames. One end of the connecting column is fixedly connected to the bottom of the tray, and the other end of the connecting column extends into the interior of the positioning frame. The positioning component is fixedly connected to the bottom end of the connecting column. One end of the compression spring is fixedly connected to the inner side of the vertical plate, and the snap-fit ​​component is fixedly connected to the other end of the compression spring.

[0007] Preferably, the interior of the vehicle body is provided with an adjustment mechanism, which includes a connecting block, a bidirectional threaded rod, a limiting rod, and a cross plate. One end of the connecting block is fixedly connected to the bottom of the upright plate, and the other end of the connecting block extends into the interior of the vehicle body. One end of the bidirectional threaded rod is connected to the inner wall of the vehicle body through a bearing, and the other end of the bidirectional threaded rod extends to the front side of the vehicle body. The two cross plates are fixedly connected to the bottom of the connecting block, and both cross plates are threaded to the surface of the bidirectional threaded rod.

[0008] Preferably, the top of the vehicle body is provided with a movable groove, and the connecting blocks are slidably connected to the inside of the movable groove.

[0009] Preferably, a knob is fixedly connected to the end of the bidirectional threaded rod, and the knob is circular in shape.

[0010] Preferably, the snap-fit ​​component is trapezoidal in shape, and the top and bottom of the side surface of the positioning component are provided with inclined surfaces that cooperate with the snap-fit ​​component, and the snap-fit ​​component is in close contact with the surface of the positioning component.

[0011] Preferably, a round rod is movably disposed inside the compression spring, one end of which is fixedly connected to the outside of the snap-fit ​​member, and the other end of which is slidably connected to the inside of the upright plate.

[0012] Preferably, an auxiliary positioning plate is fixedly connected to the top of the positioning frame, the top of the auxiliary positioning plate is inclined outward, and the auxiliary positioning plate is connected to the upright plate.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when positioning and installing the pallet on the vehicle body, the pallet can be placed on the positioning frame on the top of the vehicle body, and the connecting post and positioning component at the bottom of the pallet can be passed through the connecting frame. When the positioning component passes through the connecting frame, it will smoothly press the snap-fit ​​component outward under the inclined surface of the positioning component. The snap-fit ​​component will also press the compression spring, and then the positioning component will move to the bottom of the snap-fit ​​component. Under the rebound of the compression spring, the inclined surface on the bottom side of the snap-fit ​​component will be pushed into close contact with the inclined surface on the top side of the positioning component. Thus, under the close contact and obstruction of the snap-fit ​​component and the positioning component, the positioning component is limited to the inside of the positioning frame. At the same time, the pallet can be automatically positioned on the positioning frame, avoiding the tedious process of manual operation and reducing the dependence on the operator.

[0015] In this invention, the spacing of the positioning frames can be adjusted according to the size of the pallet to enable positioning and installation of pallets of different sizes. When adjusting the spacing of the positioning frames, the double-threaded rod can be rotated clockwise by turning the knob. The clockwise rotation of the double-threaded rod will cause the two threaded horizontal plates to move inward simultaneously under the guidance and limitation of the limiting rod. The simultaneous inward movement of the two horizontal plates will simultaneously drive the connecting block and the top positioning frame to move inward simultaneously. Conversely, counterclockwise rotation will cause the positioning frames to move outward simultaneously. Thus, the distance can be flexibly adjusted according to the size of the pallet, which can adapt to different specifications of pallets and support the positioning of pallets of various sizes, reducing the dependence on fixed-size pallets.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4As shown, an automatic positioning device for a Pack cart includes a cart body 1 and a pallet 101. The pallet 101 is disposed on the top of the cart body 1, and an automatic positioning mechanism is disposed on the top of the cart body 1. The automatic positioning mechanism includes a positioning frame 201, a vertical plate 202, a connecting column 203, a positioning component 204, a compression spring 205, and a snap-fit ​​component 206. Several positioning frames 201 are installed on the top of the cart body 1. The vertical plates 202 are respectively fixedly connected to the rear side of the positioning frames 201. One end of the connecting column 203 is fixedly connected to the bottom of the pallet 101, and the other end of the connecting column 203 extends into the interior of the positioning frame 201. The positioning component 204 is fixedly connected to the bottom end of the connecting column 203. One end of the compression spring 205 is fixedly connected to the inner side of the vertical plate 202, and the snap-fit ​​component 206 is fixedly connected to the other end of the compression spring 205. Through the use of the automatic positioning mechanism, human intervention is reduced, which can save the time for positioning and installing the pallet 101 and reduce operating costs. Especially in the process of large-scale transportation and storage, it can effectively improve the smoothness of work.

[0024] like Figure 3 As shown, the interior of the vehicle body 1 is equipped with an adjustment mechanism, which includes a connecting block 301, a bidirectional threaded rod 302, a limiting rod 303, and a horizontal plate 304. One end of the connecting block 301 is fixedly connected to the bottom of the vertical plate 202, and the other end of the connecting block 301 extends into the interior of the vehicle body 1. One end of the bidirectional threaded rod 302 is connected to the inner wall of the vehicle body 1 via a bearing, and the other end of the bidirectional threaded rod 302 extends to the front side of the vehicle body 1. Two horizontal plates 304 are fixedly connected to the bottom of the connecting block 301, and both horizontal plates 304 are threaded to the surface of the bidirectional threaded rod 302. Through the coordinated use of the adjustment mechanism, the spacing of the positioning frame 201 can be smoothly adjusted by rotating the bidirectional threaded rod 302, so that the positioning frame 201 can be positioned and installed with pallets 101 of different sizes. This allows for flexible adaptation to the needs of pallets 101 of different sizes, enabling the same vehicle body 1 to carry pallets 101 of different specifications, thus improving the applicability and flexibility of the vehicle body 1.

[0025] like Figure 2 As shown, the top of the vehicle body 1 is provided with a movable groove 4, and the connecting blocks 301 are slidably connected to the inside of the movable groove 4. When adjusting the spacing of the positioning frame 201, the crossbar can drive the connecting blocks 301 to slide inside the movable groove 4, so that the connecting blocks 301 can drive the top mechanism to move smoothly during adjustment, preventing the connecting blocks 301 from colliding with the vehicle body 1 during movement and causing motion interference, and affecting the adjustment of the spacing of the positioning frame 201.

[0026] like Figure 1 and Figure 3As shown, a knob 5 is fixedly connected to the end of the bidirectional threaded rod 302. The knob 5 is circular in shape. When rotating the bidirectional threaded rod 302, the bidirectional threaded rod 302 can be smoothly rotated by holding the knob 5 to make precise adjustments. This reduces the difficulties and inconvenience that may occur when rotating the bidirectional threaded rod 302 directly by hand, and can improve the overall adjustment accuracy.

[0027] like Figure 4 As shown, the snap-fit ​​component 206 is trapezoidal in shape. The top and bottom of the side surface of the positioning component 204 are provided with inclined surfaces that cooperate with the snap-fit ​​component 206. The snap-fit ​​component 206 and the surface of the positioning component 204 are in close contact. When the positioning component 204 is positioned inside the positioning frame 201, the inclined surface on the bottom side of the positioning component 204 will cooperate with the inclined surface on the top side of the trapezoidal snap-fit ​​component 206, so that the positioning component 204 can automatically slide to the bottom of the snap-fit ​​component 206. Under the elastic force of the compression spring 205, the snap-fit ​​component 206 and the positioning component 204 are pushed to make close contact through the inclined surface, so that the positioning component 204 can be positioned and blocked. When it is necessary to disassemble the tray 101, the tray 101 can be lifted directly upwards. Conversely, the positioning component 204 can be pulled upwards, and the inclined surfaces of the two can cooperate to reduce resistance, so that the positioning component 204 can be quickly separated from the inner pull of the positioning frame 201 and the tray 101 can be separated from the vehicle body 1.

[0028] like Figure 4 As shown, a round rod 6 is movably arranged inside the compression spring 205. One end of the round rod 6 is fixedly connected to the outside of the snap-fit ​​member 206, and the other end of the round rod 6 is slidably connected to the inside of the upright plate 202. When the compression spring 205 and the snap-fit ​​member 206 are squeezed outward, the snap-fit ​​member 206 will drive the round rod 6 to move outward. With the cooperation of the round rod 6 and the upright plate 202, it can assist in guiding the snap-fit ​​member 206 to move parallel. When the compression spring 205 pushes the snap-fit ​​member 206 to block and limit the positioning member 204, the snap-fit ​​member 206 will deviate and will not be able to stably snap-fit ​​and position with the positioning member 204.

[0029] like Figure 1 and Figure 4 As shown, an auxiliary positioning plate 7 is fixedly connected to the top of the positioning frame 201. The top of the auxiliary positioning plate 7 is tilted outward. The auxiliary positioning plate 7 is connected to the upright plate 202. When positioning the pallet 101, the outward tilting design of the auxiliary positioning plate 7 helps to guide the pallet 101 to the correct position during the positioning process. Through the tilting guide, the positioning member 204 at the bottom of the pallet 101 can slide smoothly into the positioning frame 201 to ensure accurate alignment.

[0030] The working principle of this utility model is as follows: When the tray 101 is positioned and installed on the vehicle body 1, the tray 101 can be placed on the positioning frame 201 at the top of the vehicle body 1, and the connecting post 203 and the positioning member 204 at the bottom of the tray 101 pass through the connecting frame. When the positioning member 204 passes through the connecting frame, it will smoothly press the snap-fit ​​member 206 outward under the inclined surface of the positioning member 204. The snap-fit ​​member 206 will also press the compression spring 205, and then the positioning member 204 will move to the bottom of the snap-fit ​​member 206. Under the rebound of the compression spring 205, the inclined surface of the bottom side of the snap-fit ​​member 206 will be pushed to make close contact with the inclined surface of the top side of the positioning member 204. Thus, under the close contact and blocking of the snap-fit ​​member 206 and the positioning member 204, the positioning member 204 is limited inside the positioning frame 201. At the same time, the tray 101 can be automatically positioned on the positioning frame 201, avoiding the tedious process of manual operation and reducing the dependence on the operator.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
