[0002] An automobile repair tool cart is a storage device for storing automobile repair tools. The automobile repair tools are placed in a movable body, which is convenient for mechanics to take and put tools and reduce unnecessary walking. It can effectively improve repair efficiency and store tools in an orderly manner. It is widely used in the automobile repair field. However, the existing automobile repair tool carts have a relatively simple structure and a relatively single function, and cannot meet the needs of placing repair tools and supplies of different sizes during the repair process.

[0003] For example, Chinese patent announcement No. CN217143892U discloses an expandable automobile repair tool cart. When in use, a flip-type expansion board is provided on the side wall of the main cabinet. The expansion board flips up and connects to the top of the main cabinet, so that the top work surface of the tool cart can be expanded to better meet the needs of mechanics to place items. A flip-type storage auxiliary board is provided, and a positioning table for displaying maintenance information is provided on the board. During the maintenance process, the hands of maintenance personnel are inevitably exposed to engine oil and dust, and unclean hands affect the browsing of information. The positioning table is provided to facilitate maintenance personnel to check the information. When the auxiliary board is not in use, it can be flipped down for storage without taking up space. The tool hook can be detachably installed on the threaded mounting holes opened on the main cabinet and the auxiliary board. The installation position of the tool hook can be selected according to the size of different tools. The tool hook adopts a detachable structure, which can meet the personalized needs of tool placement.

[0004] However, the expandable automobile repair tool cart in the above application cannot adjust the height of the vehicle body space, cannot store larger tools, and its extension table is set outside, resulting in the tool cart being too large and occupying space. Therefore, there are certain limitations.

[0005] To this end, we urgently need to provide an expandable tool vehicle. Utility Model Content

[0006] The purpose of the utility model is to provide an expandable tool cart to solve the problem that the expandable automobile repair tool cart proposed in the above background technology cannot adjust the height of the vehicle body space, cannot store larger tools, and its extension table is set outside, resulting in the tool cart being too large and occupying space.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an expandable tool cart, comprising a storage plate and a cart handle, wherein the storage plates have three pieces in total, and the three storage plates are vertically arranged. The left side of the top storage plate is fixedly connected to the cart handle, a distance adjusting device is arranged between the storage plates, an expansion device is arranged on the right side of the storage plate, and buffer devices are respectively arranged at the four corners of the lower surface of the bottom storage plate.

[0008] The distance adjustment device includes a support column, a sliding rod, and a positioning assembly.

The four sliding rods are respectively slidably connected to the inside of the support columns, and their tops are fixedly connected to the bottom of the upper storage plate. Two groups of positioning assemblies are respectively installed on the front top of the left support column at the front end and the back top of the right support column at the rear end.

[0009] A further improvement is that the positioning assembly includes a mounting block, a fixing rod, and a tension spring, wherein the mounting block is fixedly connected to the front top of the support column, the fixing rod is installed at the front center of the mounting block, and the tension spring is installed around the outer surface of the fixing rod.

[0010] A further improvement is that a sliding hole is opened on the front of the mounting block, the fixing rod is slidably connected to the inside of the sliding hole, positioning holes are opened vertically and equidistantly on the front of the sliding rod, and the tail end of the fixing rod is inserted into the inside of the positioning hole.

[0011] A further improvement is that a spring compartment is provided inside the sliding hole, and one end of the tension spring is installed on the inner wall of the spring compartment. When a larger tool needs to be stored, the fixing rod is pulled to slide out from the inside of the sliding hole and squeeze the tension spring. At this time, the sliding rod is pulled upward from the inside of the support column until the height between the two storage plates reaches the required requirement. The fixing rod is released, and the tension spring is reset under the action of its own elasticity, thereby driving the fixing rod to slide into the inside of the sliding hole and snap into the inside of the positioning hole on the sliding rod, thereby fixing the height and improving the applicability of the tool cart.

[0012] A further improvement is that the expansion device includes an expansion plate, a connecting ear plate, a magnetic rod, and a handle.

[0013] A further improvement is that a push-pull groove is provided on the right outer surface of the storage plate, and the expansion plate is slidably connected to the inside of the push-pull groove. Plug holes are respectively provided on the front and rear sides of the left outer surface of the storage plate, and magnetic blocks are installed on the inner walls of the plug holes. The magnetic rod is plugged into the inside of the plug hole. When it is necessary to expand the use space of the storage plate, pull the handle to pull the expansion plate out from the inside of the push-pull groove. After use, push the expansion plate back into the inside of the push-pull groove. At this time, the magnetic rods connecting the two sides of the ear plate slide into the inside of the plug hole and attract each other with the magnetic blocks inside, thereby improving the stability of storage and not taking up space.

[0014] A further improvement is that the buffer device includes a buffer spring, a self-locking wheel, a sleeve, and a damping slide rod, the buffer spring is fixedly connected to the bottom of the storage plate, the self-locking wheel is fixedly connected to the bottom of the buffer spring, the sleeve is fixedly connected to the upper surface of the self-locking wheel and is located inside the buffer spring, the damping slide rod is slidably connected to the inside of the sleeve, and the top of the damping slide rod is connected to the lower surface of the storage plate. When encountering a bumpy road section, the impact force exerted on the tool on the storage plate squeezes the storage plate downward to squeeze the buffer spring, thereby utilizing the elasticity of the buffer spring to absorb and release the impact force, and the damping slide rod and the sleeve cooperate to prevent the buffer spring from being distorted by impact and affecting its use.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the expandable tool cart needs to store larger tools, the fixing rod is pulled to slide out from the inside of the sliding hole and squeeze the tension spring. At this time, the sliding rod is pulled upward from the inside of the support column until the height between the two storage plates reaches the required requirement. The fixing rod is released, and the tension spring is reset under the action of its own elasticity, thereby driving the fixing rod to slide into the inside of the sliding hole and snap into the inside of the positioning hole on the sliding rod, thereby fixing the height and improving the application range of the tool cart.

[0017] 2. For the expandable tool cart, when it is necessary to expand the use space of the storage board, pull the handle to pull the expansion board out from the inside of the push-pull slot. After use, push the expansion board back into the inside of the push-pull slot. At this time, the magnetic rods connecting the two sides of the ear plate slide into the inside of the plug-in hole and attract each other with the magnetic blocks inside, thereby improving the stability of storage and not taking up space.

[0018] 3. When the expandable tool cart encounters a bumpy road, the impact force exerted on the tools on the storage plate squeezes the storage plate downward to squeeze the buffer spring, thereby utilizing the elasticity of the buffer spring to absorb and release the impact force. The damping slide rod and the sleeve cooperate to prevent the buffer spring from being distorted by the impact and affecting its use. BRIEF DESCRIPTION OF THE DRAWINGS
