Description

Technical Field

[0001] This utility model belongs to the technical field of material handling vehicles, specifically relating to a material handling vehicle for laboratory construction. Background Technology

[0002] Laboratory construction material handling carts are generally designed for moving and transporting various materials in laboratory environments. These carts typically need to possess certain specific characteristics and functions to meet the demands of the laboratory environment, such as being lightweight yet robust: the carts need to be strong enough to carry items of varying weights, while also being lightweight and flexible enough to move and operate easily in narrow laboratory aisles.

[0003] Existing laboratory construction material handling vehicles have the following drawbacks during use:

[0004] Commonly, four rolling structures, such as rollers, are installed around the bottom of the transport vehicle. When using the transport vehicle to move materials needed for laboratory construction, multiple materials are usually tied to the transport vehicle with ropes, which makes securing multiple materials very inconvenient. In addition, due to the design of the rolling structure, it is not possible to quickly stabilize the transport vehicle between itself and the ground when unloading materials, which makes the transport vehicle prone to movement during the unloading process, thus affecting the efficiency of material handling. Therefore, a material transport vehicle for laboratory construction is needed. Utility Model Content

[0005] The purpose of this invention is to provide a material handling vehicle for laboratory construction, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material handling vehicle for laboratory construction, comprising a mobile carriage, wherein rollers are rotatably connected to the bottom of the mobile carriage, the cross-section of the mobile carriage is U-shaped, a push handle is fixedly connected to the rear side wall of the mobile carriage, a manual positioning structure is installed on the mobile carriage to facilitate clamping and fixing multiple plates of equal width, and a linkage top support stabilizing structure is installed on both side walls of the mobile carriage, the linkage top support stabilizing structure being connected to the manual positioning structure.

[0007] In a preferred embodiment, the manual positioning structure includes movable channels opened on both sides of the mobile carriage. The vertical cross-section of the movable channels is I-shaped. The same U-shaped movable plate is movably inserted in the two movable channels. A screw is threadedly connected to the middle of the U-shaped movable plate. One end of the screw is rotatably connected to the rear side wall of the mobile carriage, and the other end is fixedly connected to a handwheel.

[0008] In a preferred embodiment, push-pull rods are hinged to the inner walls of both sides of the U-shaped movable plate, and the other ends of the two push-pull rods are hinged to the back of the positioning plate. The bottom ends of the positioning plates slide on the inner bottom wall of the mobile carriage. Guide rods are fixed around the four sides of the opposite side walls of the two positioning plates, and the other ends of the guide rods movably pass through the mobile carriage.

[0009] In one preferred embodiment, the linkage top support stabilizing structure includes transmission columns fixed to the outer walls of both sides of the U-shaped movable plate. Transmission plates are movably sleeved on the outer side of each transmission column, and each transmission plate has a transmission channel that cooperates with the transmission column. The vertical cross-section of each transmission channel is shaped like a hockey stick.

[0010] In a preferred embodiment, the transmission plates are slidably sleeved on the outside of two symmetrically arranged C-shaped rods, and the C-shaped rods are fixed to the outside of the moving carriage.

[0011] In a preferred embodiment, the bottom end of each transmission plate is fixed to a base plate by two symmetrically arranged connecting rods, and the bottom end of each base plate is fixed with multiple conical blocks.

[0012] Compared with the prior art, the laboratory construction material handling vehicle provided by this utility model has at least the following beneficial effects:

[0013] In this utility model, when using the laboratory construction material transport vehicle, multiple laboratory construction materials of the same size and specifications can be vertically stacked on the mobile carriage. By rotating the screw via the handwheel, the U-shaped movable plate moves away from the rear wall of the mobile carriage through two moving channels. This, combined with the action of the two push-pull rods, allows the two positioning plates to move relative to each other, facilitating the clamping and fixing of the multiple vertically stacked construction materials on the mobile carriage. Due to the design of the transmission column and transmission channels, the transmission plates are all moved upwards and fixed at a certain height on the outside of the two C-shaped rods. The base plate, which is connected to the bottom of both connecting rods, moves upward to remove its support to the ground, thus facilitating the clamping and fixing of multiple vertically stacked boards. This allows users to push and transport the boards using the material handling vehicle. During unloading, the screw can be flipped using the handwheel, causing the two positioning plates to move away from each other and remove the clamping and fixing of multiple boards. In addition, both transmission plates will move downward, causing the base plate connected to the two connecting rods to move downward, driving multiple conical blocks to support the ground. This ensures the stability of the handling vehicle and the ground when handling boards, preventing the handling vehicle from moving arbitrarily and interfering with the manual handling of the boards.

All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention.

[0021] Example

[0022] Commonly, four rolling structures, such as rollers 2, are installed around the bottom of the transport vehicle. When using the transport vehicle to move the boards required for laboratory construction, multiple boards are usually tied to the transport vehicle with ropes, which makes it very inconvenient to fix multiple boards. In addition, due to the design of the rolling structure, it is not possible to quickly achieve stability between the transport vehicle and the ground when unloading boards, which makes the transport vehicle prone to movement when unloading boards, thus affecting the efficiency of unloading boards.

[0023] For this purpose, please refer to Figure 1-3This utility model provides a material handling vehicle for laboratory construction, including: a mobile carriage 1, with rollers 2 rotatably connected to the bottom of the mobile carriage 1 around its four sides, the cross-section of the mobile carriage 1 having a U-shaped structure, a push handle 3 fixedly connected to the rear side wall of the mobile carriage 1, a manual positioning structure 4 installed on the mobile carriage 1 for facilitating the clamping and fixing of multiple plates of equal width, and a linkage top support stabilizing structure 5 installed on both side walls of the mobile carriage 1, the linkage top support stabilizing structure 5 being connected to the manual positioning structure 4.

[0024] Further as Figure 1-3 As shown, it is worth noting that in order to facilitate the simultaneous clamping and fixing of multiple plates, a manual positioning structure 4 is provided, including a moving channel 411 opened on both sides of the moving carriage 1. The vertical cross-section of the moving channel 411 is I-shaped. The same U-shaped movable plate 41 is movably inserted in the two moving channels 411. A screw 42 is threadedly connected to the middle of the U-shaped movable plate 41. One end of the screw 42 is rotatably connected to the rear side wall of the moving carriage 1, and the other end is fixedly connected to a handwheel 43. Push-pull rods 44 are hinged to the inner walls on both sides of the U-shaped movable plate 41. The other ends of the two push-pull rods 44 are hinged to the back of the positioning plate 45. The bottom ends of the positioning plates 45 slide on the inner bottom wall of the moving carriage 1. Guide rods 46 are fixedly connected to the four sides of the opposite side wall of the two positioning plates 45. The other ends of the guide rods 46 movably pass through the moving carriage 1.

[0025] The manual positioning structure 4 facilitates clamping and fixing of multiple construction slabs of different widths.

[0026] Further as Figure 1-3 As shown, it is worth noting that in order to enable the transport vehicle to be fixed to the ground when the above-mentioned manual positioning structure 4 is used to loosen and unload multiple plates, a linkage top support stabilization structure 5 is set up, which includes transmission columns 51 fixed to the outer walls of both sides of the U-shaped movable plate 41. Transmission plates 52 are movably sleeved on the outer side of the transmission columns 51. Transmission channels 53 that cooperate with the transmission columns 51 are opened on the transmission plates 52. The vertical cross section of the transmission channels 53 is shaped like a hockey stick. The transmission plates 52 are slidably sleeved on the outer side of two symmetrically arranged C-shaped rods 54. The C-shaped rods 54 are fixed to the outer side of the mobile carriage 1. The bottom end of the transmission plates 52 is fixed to a base plate 56 through two symmetrically arranged connecting rods 55. Multiple conical blocks are fixed to the bottom end of the base plate 56.

[0027] The width of the transmission channel 53 is equal to the diameter of the transmission column 51.

[0028] In summary: When using this laboratory construction material handling vehicle, multiple construction materials of the same size can be vertically stacked on the mobile carriage 1. The screw 42 is rotated via the handwheel 43, causing the U-shaped movable plate 41 to move away from the rear wall of the mobile carriage 1 within the two moving channels 411. This, combined with the action of the two push-pull rods 44, allows the two positioning plates 45 to move relative to each other. This facilitates the clamping and fixing of the multiple construction materials vertically stacked on the mobile carriage 1. Due to the design of the transmission column 51 and transmission channel 53, the transmission plate 52 is fixed at an upward height on the outside of the two C-shaped rods 54. At this time, the base plate 56, which is connected to the bottom of both connecting rods 55, moves up to remove the support to the ground, thereby facilitating the clamping and fixing of multiple vertically stacked plates. This allows the user to push and transport the plates using the material handling vehicle. During unloading, the screw 42 can be flipped using the handwheel 43, causing the two positioning plates 45 to move away from each other and remove the clamping and fixing of multiple plates. In addition, both transmission plates 52 will move down, causing the base plate 56 connected to the two connecting rods 55 to move down and drive multiple conical blocks to support the ground, ensuring the stability between the handling vehicle and the ground when handling plates and preventing the handling vehicle from moving arbitrarily and interfering with the manual handling of the plates.
