[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4 A plastic tool cart comprises an upper tray 1, a middle tray 2 and a lower tray 3 which are arranged in sequence from top to bottom. The upper tray 1 and the middle tray 2 as well as the middle tray 2 and the lower tray 3 are connected and fixed by four columns 4, and the four corners of the lower bottom surface of the lower tray 3 are provided with universal wheels 5 for installing. The four corners of the lower bottom surface of the lower tray 3 are provided with mounting positions 31, and reinforcement blocks 6 are installed on the mounting positions 31, and universal wheels 5 are installed on the reinforcement blocks 6. This arrangement is more suitable for plastic tool carts, greatly improves the firmness of the structure, and improves the service life.

[0028] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 3 and Figure 4 As shown, each mounting position 31 includes a base 311 arranged on the four corners of the lower end surface of the lower tray 3, the base 311 is provided with a mounting groove 312, the mounting groove 312 is provided with a fixing seat 313, and the fixing seat 313 is provided with a fixing groove 314. The base 311 and the fixing seat 313 are integrally formed with the lower tray 3, which greatly improves the structural firmness.

[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, each reinforcing block 6 includes a main body 61 for being installed in the mounting groove 312, a mounting hole 62 for matching with the fixing seat 313 is opened in the middle of the main body 61, and protrusions 63 are evenly distributed on the inner side wall of the mounting hole 62. The mounting hole 62 and the fixing seat 313 are clearance-matched, which is conducive to strengthening the firmness of the fixing seat 313.

[0030] Among them, Figure 1 As shown, each universal wheel 5 includes a bracket 51 and a roller 52 arranged at the lower part of the bracket 51, and a connecting rod 53 is arranged at the upper part of the bracket 51. The connecting rod 53 rotates on the bracket 51 (it can be rotated by a bearing, or in this embodiment, the rotation is achieved by a ball connection between the upper end of the bracket 51 and the lower end of the connecting rod 53). This is conducive to achieving universal rotation of the universal wheel 5. The connecting rod 53 cooperates with the fixing groove 314, so that the connecting rod 53 is inserted into the fixing groove 314 for fixing. Since the connecting rod 53 is made of plastic, this is conducive to strengthening the firmness of the universal wheel 5 through the reinforcing block 6.

[0031] Embodiment 3: It can be described on the basis of embodiment 1 or embodiment 2 that the lower end surfaces of the upper tray 1 and the middle tray 2 are provided with mounting positions 31 that are consistent with the lower end surface of the lower tray 3. This is beneficial to the upper tray 1 and the middle tray 2. This is beneficial for the upper tray 1 and the middle tray 2 to also be suitable for the lower tray 3, which is more versatile and facilitates installation.

[0032] Embodiment 4: It can be explained on the basis of embodiment 1 or embodiment 2 or embodiment 3 that the number of the middle trays 2 can be determined according to actual conditions, which is more conducive to meeting the usage requirements of different users.

[0033] When the utility model is in use, it is only necessary to install each reinforcement block 6 into the corresponding installation position 31, and then install the corresponding universal wheel 5 into the installation position 31. This is beneficial to greatly improve the firmness of the universal wheel 5 installed on the lower tray 3, and is particularly suitable for plastic tools, which greatly improves the service life.

[0034] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the existing technology, which will not be described in detail here.

[0035] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
