Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a tool trolley capable of moving and lifting. Background Technology

[0002] In product assembly and repair sites, various tools and spare parts are frequently used. To facilitate their use, these tools and spare parts are usually stored together in a toolbox. However, due to the actual needs of assembly and repair, personnel sometimes need to operate at different heights. This requires them to frequently bend over to retrieve tools, which is inconvenient. Furthermore, different operators have different heights, so the most convenient height for reaching the tools varies for different people.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The technical problem this utility model aims to solve is that maintenance and assembly personnel need to operate at different heights, which requires them to frequently bend over to retrieve tools, making it inconvenient to use. The purpose is to provide a tool trolley that can be moved and lifted, and whose height can be adjusted according to actual needs, so that the tools are placed at the optimal height for easy use by assembly and maintenance personnel, improving user comfort, and facilitating the transportation and storage of tools.

[0005] This utility model is achieved through the following technical solution:

[0006] A tool trolley capable of being moved and lifted includes a trolley base, a tool storage area is provided above the trolley base, and a scissor lift structure is provided between the tool storage area and the trolley base;

[0007] The scissor lift structure includes a scissor lift mechanism and a ramp lift mechanism at both ends of the trolley base. The scissor lift mechanism includes two lifting rods arranged in a cross shape, and the two lifting rods are hinged at the center intersection.

[0008] One of the lifting rods has a slidable inclined block lifting mechanism at its lower end. Pushing the inclined block lifting mechanism toward the center of the intersection of the two lifting rods causes the scissor lifting mechanism to lower and retract, pushes the inclined block lifting mechanism toward the lower end of the lifting rod, and raises and extends the scissor lifting mechanism.

[0009] The tool cart of this utility model can adjust its height according to actual needs, so that the tools are placed at the optimal height for assembly and maintenance personnel to use, thereby improving the comfort of use and facilitating the transportation and storage of tools.

[0010] In this invention, tools can be stored in the tool storage area, and the tool cart can be raised and lowered to retract through the cooperation of the inclined block lifting mechanism and the scissor lifting mechanism.

[0011] In one specific embodiment, the lower end of the inclined block lifting mechanism is slidably connected to the trolley base, the inclined block lifting mechanism is provided with an inclined strip-shaped through hole, and a limit post is provided on the side wall of the lifting rod, the limit post being slidably connected to the strip-shaped through hole.

[0012] In this utility model, since the lower end of the inclined block lifting mechanism is slidably connected to the trolley base, when the inclined block lifting mechanism moves horizontally, the inclined strip-shaped through hole moves synchronously. Therefore, under the action of the strip-shaped through hole, the limiting post moves up or down along the inclined strip-shaped through hole, thereby driving the lifting rod to rotate and realize the raising or lowering of the scissor-type lifting mechanism.

[0013] The tool cart in the raised, extended state allows operators to easily access tools or items, and the operating height is suitable, making the operator feel more comfortable. In the lowered, folded state, it reduces the footprint and makes the entire tool cart more convenient to transport and use.

[0014] In one specific embodiment, the strip-shaped through hole is higher at the end where the two lifting rods intersect at the center, and lower at the end towards the lower end of the lifting rods. When the inclined block lifting mechanism moves towards the center, the limiting post moves downward under the action of the strip-shaped through hole, causing the scissor lifting mechanism to descend and retract. When the inclined block lifting mechanism moves outward from the center, the limiting post moves upward under the action of the strip-shaped through hole, causing the scissor lifting mechanism to rise and unfold. At this time, the inclined block lifting mechanism is at the angle formed by the lower end of the lifting rod and the trolley base, which further supports the lifting rod.

[0015] In one specific embodiment, a drive rod is provided between the two scissor lift mechanisms. The two ends of the drive rod are respectively connected to the inclined block lift mechanisms on both sides. A hand crank screw is provided between the drive rod and the trolley base. By rotating the hand crank screw, the drive rod is driven to move towards the inside of the tool trolley.

[0016] In one specific embodiment, a threaded sleeve is fitted onto the hand-cranked lead screw, the threaded sleeve is slidably connected to the threaded sleeve base, and the drive rod is mounted on the threaded sleeve.

[0017] By rotating the hand crank screw, which only produces linear motion in two directions (eastward and westward), the rotational motion of the hand crank screw is converted into linear motion of the screw sleeve, thereby driving the drive rod to make linear motion, which in turn drives the back-and-forth motion of the inclined block lifting mechanism.

[0018] In one specific embodiment, a rotating disk is provided at the end of the hand crank screw, which makes it easier to operate and rotate the hand crank screw.

[0019] In one specific embodiment, the bottom of the trolley base is provided with rollers equipped with brakes, which makes it easier to move the tool trolley.

[0020] In one specific embodiment, the tool storage area includes a lower tool storage compartment and an upper tool storage compartment. The lower and upper tool storage compartments are designed to overlap and be pulled out, which facilitates the classification and storage of tools and a reasonable spatial layout.

[0021] In one specific embodiment, the upper tool storage compartment is provided with an operating handle, which facilitates the steering and movement of the trolley.

[0022] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0023] 1. The present invention provides a tool trolley that can be moved and lifted, the height of which can be adjusted according to actual needs, so that the tools are placed at the optimal height for assembly and maintenance personnel to use, thereby improving the comfort of use and facilitating the transportation and storage of tools.

[0024] 2. The present invention provides a tool trolley capable of being moved and lifted. Tools can be stored in the tool storage area. The tool trolley can be raised and lowered and retracted through the cooperation of the inclined block lifting mechanism and the scissor lifting mechanism.

[0025] 3. The tool trolley that can transfer and lift provided in this utility model embodiment has a sliding connection between the lower end of the inclined block lifting mechanism and the trolley base. Therefore, when the inclined block lifting mechanism moves horizontally, the inclined strip-shaped through hole moves synchronously. Therefore, under the action of the strip-shaped through hole, the limiting post moves up or down along the inclined strip-shaped through hole, thereby driving the lifting rod to rotate to realize the raising or lowering of the scissor-type lifting mechanism.

[0026] 4. This utility model provides a tool trolley capable of being moved and lifted. In its raised, extended state, the tool trolley allows operators to easily access tools or items, providing a comfortable operating height. In its lowered, folded state, it reduces the space required, further facilitating the transport and use of the entire tool trolley. Attached Figure Description

[0037] Example

[0038] like Figures 1-3 As shown in the figure, the present utility model provides a tool trolley capable of being moved and lifted, including a trolley base 200, a tool storage area is provided above the trolley base 200, and a scissor lift structure is provided between the tool storage area and the trolley base 200.

[0039] The scissor lift structure includes a scissor lift mechanism 203 and a ramp lift mechanism 202 set at both ends of the trolley base 200. The scissor lift mechanism 203 includes two lifting rods 206 arranged in a cross shape, and the two lifting rods 206 are hinged at the center intersection.

[0040] One of the lifting rods 206 has a slidable inclined block lifting mechanism 202 at its lower end. Pushing the inclined block lifting mechanism 202 toward the center of the intersection of the two lifting rods causes the scissor lifting mechanism 203 to lower and retract, push the inclined block lifting mechanism 202 toward the lower end of the lifting rod, and raise and extend the scissor lifting mechanism 203.

[0041] The tool cart of this utility model can adjust its height according to actual needs, so that the tools are placed at the optimal height for assembly and maintenance personnel to use, thereby improving the comfort of use and facilitating the transportation and storage of tools.

[0042] In this invention, tools can be stored in the tool storage area, and the tool cart can be raised and lowered to retract through the cooperation of the inclined block lifting mechanism and the scissor lifting mechanism.

[0043] In one specific embodiment, the lower end of the inclined block lifting mechanism 202 is slidably connected to the trolley base 200. The inclined block lifting mechanism 202 is provided with an inclined strip-shaped through hole 207. A limit post 208 is provided on the side wall of the lifting rod 206. The limit post 208 is slidably connected to the strip-shaped through hole 207.

[0044] In this utility model, since the lower end of the inclined block lifting mechanism is slidably connected to the trolley base, when the inclined block lifting mechanism moves horizontally, the inclined strip-shaped through hole moves synchronously. Therefore, under the action of the strip-shaped through hole, the limiting post moves up or down along the inclined strip-shaped through hole, thereby driving the lifting rod to rotate and realize the raising or lowering of the scissor-type lifting mechanism.

[0045] The tool cart in the raised, extended state allows operators to easily access tools or items, and the operating height is suitable, making the operator feel more comfortable. In the lowered, folded state, it reduces the footprint and makes the entire tool cart more convenient to transport and use.

[0046] In one specific embodiment, the strip-shaped through hole 207 is higher at one end facing the central intersection of the two lifting rods 206 and lower at the other end facing the lower end of the lifting rods 206. When the inclined block lifting mechanism moves towards the center, the limiting post moves downward under the action of the strip-shaped through hole, causing the scissor lifting mechanism to descend and retract. When the inclined block lifting mechanism moves outward from the center, the limiting post moves upward under the action of the strip-shaped through hole, causing the scissor lifting mechanism to rise and unfold. At this time, the inclined block lifting mechanism is at the angle formed by the lower end of the lifting rod and the trolley base, which further supports the lifting rod.

[0047] In one specific embodiment, a drive rod 209 is provided between the two scissor lift mechanisms 203. The two ends of the drive rod 209 are respectively connected to the inclined block lift mechanisms 202 on both sides. A hand crank screw 201 is provided between the drive rod 209 and the trolley base 200. By rotating the hand crank screw 201, the drive rod 209 is driven to move toward the inside of the tool trolley.

[0048] In one specific embodiment, a threaded sleeve is fitted onto the hand crank screw 201, the threaded sleeve is slidably connected to the threaded sleeve base, and the drive rod 209 is mounted on the threaded sleeve.

[0049] By rotating the hand crank screw, which only produces linear motion in two directions (eastward and westward), the rotational motion of the hand crank screw is converted into linear motion of the screw sleeve, thereby driving the drive rod to make linear motion, which in turn drives the back-and-forth motion of the inclined block lifting mechanism.

[0050] In one specific embodiment, a rotating disk is provided at the end of the hand crank screw 201, which makes it easier to operate and rotate the hand crank screw.

[0051] In one specific embodiment, the bottom of the trolley base 200 is provided with rollers with brakes, which makes it easier to move the tool trolley.

[0052] In one specific embodiment, the tool storage area includes a lower tool storage compartment 204 and an upper tool storage compartment 205. The lower tool storage compartment 204 and the upper tool storage compartment 205 are designed to overlap and pull out, which facilitates the classification and storage of tools and a reasonable spatial layout.

[0053] In one specific embodiment, the upper tool storage compartment 205 is provided with an operating handle, which facilitates the steering and movement of the trolley.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
