[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a transfer trolley for automotive parts manufacturing. Background Technology

[0002] A transfer trolley for automotive parts production is a tool used to move and transfer various parts during the automotive parts production process.

[0003] Automotive parts production trolleys are typically equipped with multiple storage boxes for storing automotive parts. However, existing trolleys have non-adjustable storage box heights, and given the wide variety of automotive parts with significant differences in size, shape, and weight, insufficient storage box height can prevent proper placement of parts. This results in low space utilization of the trolley and increased transportation costs. Utility Model Content

[0004] The purpose of this utility model is to provide a transfer trolley for the production of automotive parts, in order to solve the problem mentioned in the background art that the existing transfer trolleys have non-adjustable height between storage boxes. Since there are many types of automotive parts with huge differences in size, shape and weight, the storage boxes are not high enough to be placed properly, which greatly reduces the space utilization of the transfer trolley and increases the transfer cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transfer trolley for automotive parts production, comprising a mobile trolley body, a push handle fixedly connected to the surface of the mobile trolley body, a fixed frame fixedly connected to the surface of the mobile trolley body, a lifting mechanism provided on the surface of the fixed frame, the lifting mechanism including a guide block slidably connected to the surface of the fixed frame, a lifting frame fixedly connected to the surface of the fixed frame, a storage box slidably connected to the surface of the lifting frame, a protective cover fixedly connected to one side of the fixed frame, an adjusting screw rotatably connected to the surface of the protective cover, a knob fixedly connected to the top of the adjusting screw, a square nut threadedly connected to the surface of the adjusting screw, and the square nut fixedly connected to one side of the storage box.

[0006] Preferably, a limiting mechanism is provided on one side of the fixed frame. The limiting mechanism includes a guide plate, which is fixedly connected to the surface of the fixed frame. A spring is fixedly connected to the surface of the guide plate, and a limiting plate is fixedly connected to the surface of the spring. The limiting plate is slidably connected to the surface of the guide plate, and a limiting groove is formed on the surface of the storage box.

[0007] Preferably, the fixed frame and the lifting frame are in a U-shape, the fixed frame has a trapezoidal groove on its surface, the guide block slides in a trapezoidal shape on the trapezoidal groove of the fixed frame, and the lifting frame slides on the surface of the fixed frame via the guide block.

[0008] Preferably, the storage box has a guide groove on its surface, the storage box slides on the guide groove of the lifting frame, multiple sets of lifting frame and storage box are provided, the fixed frame has a guide hole on its surface, and the square nut slides on the guide hole of the fixed frame.

[0009] Preferably, the adjusting screw is driven to rotate by a knob, and the adjusting screw drives the square nut to slide on the guide hole of the fixed frame by rotation. The square nut drives the lifting frame and the storage box to slide and rise synchronously.

[0010] Preferably, the limiting plate is T-shaped, and the height of the limiting plate is greater than the sliding range of the lifting frame on the fixed frame. The elastic force of the spring acts on the limiting plate, and the limiting plate restricts the storage box on the guide groove of the lifting frame on one side of the lifting frame.

[0011] Preferably, multiple sets of limiting grooves are provided, and the limiting grooves are arranged linearly and evenly on one side of the storage box, with one end of the limiting plate inserted into the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This transfer trolley allows the operator to rotate a knob, which in turn rotates an adjusting screw, causing a square nut to slide on a guide hole in a fixed frame. This, in turn, causes the lifting frame and storage boxes to rise and fall synchronously. As multiple storage boxes rise and fall on the surface of the fixed frame, the spacing between them can be adjusted. This allows the trolley to flexibly adjust the height of the storage boxes when handling automotive parts of different sizes, effectively utilizing the space of the trolley and significantly improving its space utilization rate, thereby reducing transfer costs.

[0013] 2. In this transfer trolley, the spring force acts on the limiting plate, causing the limiting plate to contact and connect to one side of the storage box, stably restricting the storage box on the guide groove of the lifting frame. This prevents the storage box from sliding during transfer, ensuring the stability of the storage box during movement. At the same time, the limiting plate can be inserted into any set of linearly and evenly arranged limiting grooves on one side of the storage box, precisely limiting the sliding storage box, facilitating the user's operation of picking up and putting down automotive parts on the storage box, and greatly improving the convenience of operation.

[0016] 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.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A transfer trolley for automotive parts production includes a mobile trolley body 1, a handle 11 fixedly connected to the surface of the mobile trolley body 1, a fixed frame 2 fixedly connected to the surface of the mobile trolley body 1, a lifting mechanism provided on the surface of the fixed frame 2, the lifting mechanism including a guide block 21 slidably connected to the surface of the fixed frame 2, a lifting frame 22 fixedly connected to the surface of the fixed frame 2, a storage box 23 slidably connected to the surface of the lifting frame 22, and a protective cover 24 fixedly connected to one side of the fixed frame 2. An adjusting screw 25 is rotatably connected to the surface of the storage box 23. A knob 26 is fixedly connected to the top of the adjusting screw 25. A square nut 27 is threadedly connected to the surface of the adjusting screw 25. The square nut 27 is fixedly connected to one side of the storage box 23. The storage box 23 is used to store automotive parts. Multiple sets of storage boxes 23 can be raised and lowered on the surface of the fixed frame 2 to change the spacing between the multiple sets of storage boxes 23. This allows the height of the storage box 23 to be adjusted when dealing with automotive parts of different sizes, thereby effectively utilizing space, improving the space utilization rate of the transport trolley, and reducing transport costs.

[0018] Furthermore, a limiting mechanism is provided on one side of the fixed frame 2. The limiting mechanism includes a guide plate 3, which is fixedly connected to the surface of the fixed frame 2. A spring 31 is fixedly connected to the surface of the guide plate 3, and a limiting plate 32 is fixedly connected to the surface of the spring 31. The limiting plate 32 is slidably connected to the surface of the guide plate 3. A limiting groove 33 is opened on the surface of the storage box 23. The limiting mechanism simultaneously restricts the position of multiple sets of storage boxes 23 on the surface of the fixed frame 2, preventing the storage boxes 23 from sliding. In addition, the limiting plate 32, together with the limiting groove 33, can limit the limiting position of the storage box 23 on the fixed frame 2, thereby facilitating the user to operate the automotive parts on the storage box 23 and improving the convenience of operation.

[0019] Furthermore, the fixed frame 2 and the lifting frame 22 are in the shape of a "U". The surface of the fixed frame 2 has a trapezoidal groove. The guide block 21 slides on the trapezoidal groove of the fixed frame 2 in a trapezoidal shape. The lifting frame 22 slides on the surface of the fixed frame 2 through the guide block 21. During the sliding process, the lifting frame 22 drives the storage box 23 to slide up and down, thereby changing the relative height between multiple sets of storage boxes 23.

[0020] Furthermore, a guide groove is provided on the surface of the storage box 23. The storage box 23 slides on the guide groove of the lifting frame 22. The storage box 23 changes the positional relationship between the lifting frame 22 and the storage box 23 by sliding on the lifting frame 22, and can slide out to facilitate the removal of automotive parts from the storage box 23. Multiple sets of lifting frames 22 and storage boxes 23 are provided. A guide hole is provided on the surface of the fixed frame 2, and a square nut 27 slides on the guide hole of the fixed frame 2.

[0021] Furthermore, the adjusting screw 25 is driven to rotate by the knob 26. The rotating adjusting screw 25 drives the square nut 27 to slide on the guide hole of the fixed frame 2. The square nut 27 drives the lifting frame 22 and the storage box 23 to slide and rise synchronously, thereby realizing the adjustment of the height of the storage box 23. Each set of storage boxes 23 is driven to rise and fall by a single set of adjusting screws 25, ensuring ease of operation. After the adjusting screw 25 has rotated, it will be stably restricted to stop rotating due to friction, thereby ensuring the stability of the height of the storage box 23 on the fixed frame 2.

[0022] Furthermore, the limiting plate 32 is T-shaped, and its height is greater than the sliding range of the lifting frame 22 on the fixed frame 2. This allows the limiting plate 32 to limit the storage boxes 23 on multiple sets of lifting frames 22, preventing the storage boxes 23 from sliding out. The elastic force of the spring 31 acts on the limiting plate 32, and the limiting plate 32 restricts the storage box 23 to the guide groove of the lifting frame 22 on one side. At this time, the limiting plate 32 is in contact with one side of the storage box 23, ensuring the stability of the storage box 23 during movement.

[0023] Furthermore, multiple sets of limiting grooves 33 are provided, and the limiting grooves 33 are arranged linearly and evenly on one side of the storage box 23. One end of the limiting plate 32 is inserted into the limiting groove 33. The limiting plate 32 can be inserted into any set of limiting grooves 33, thereby limiting the sliding storage box 23. After the storage box 23 slides out of the movement range, it is limited by the limiting plate 32, and then the car parts on the storage box 23 can be taken out, thus facilitating the taking and putting of car parts on the storage box 23.

[0024] Working principle: The operator rotates knob 26, which drives the adjusting screw 25 to rotate. Since the adjusting screw 25 is threadedly connected to the square nut 27, and the square nut 27 is fixedly connected to one side of the storage box 23, the rotation of the adjusting screw 25 will drive the square nut 27 to slide on the guide hole of the fixed frame 2. The square nut 27 then drives the lifting frame 22 and the storage box 23 to slide and rise synchronously. At the same time, the guide block 21 slides on the trapezoidal groove of the fixed frame 2, ensuring the stability of the lifting frame 22 and the storage box 23 during the lifting process. Multiple sets of storage boxes 23 rise and fall on the surface of the fixed frame 2 in this way, changing the distance between them, thereby effectively utilizing space, improving the space utilization rate of the transfer trolley, and reducing transfer costs.

[0025] The guide plate 3 in the limiting mechanism is fixed to the surface of the fixed frame 2. One end of the spring 31 is connected to the guide plate 3, and the other end is connected to the limiting plate 32. The limiting plate 32 can slide on the surface of the guide plate 3. A limiting groove 33 is opened on the surface of the storage box 23. The elastic force of the spring 31 causes the limiting plate 32 to contact and restrict the storage box 23, preventing it from sliding on the guide groove of the lifting frame 22, thus ensuring the stability of the storage box 23 during movement. When it is necessary to take out the car parts in the storage box 23, the storage box 23 can be slid out on the guide groove of the lifting frame 22, and then one end of the limiting plate 32 is inserted into the limiting groove 33 at the appropriate position to limit the sliding storage box 23, making it convenient for the operator to take out the car parts. The limiting mechanism can simultaneously limit the position of multiple sets of storage boxes 23. With the help of the limiting groove 33, the limiting position of the storage box 23 on the fixed frame 2 is precisely limited, which greatly improves the convenience of user operation.
