[0051] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0052] In the related art, in order to save space, tool container systems are usually stacked. And in order to prevent the tool container system on the upper layer from falling and to facilitate the handling of the stacked tool container systems together, a connection locking structure is provided between the stacked objects. In the related art, the connection locking structure generally includes a first locking buckle provided on the first tool container system and a second locking bayonet provided on the second tool container system. The first locking buckle is usually placed flat on the lid of the first tool container system when not in use. When the second tool container system needs to be stacked on the first tool container system, first, the first locking buckle is flipped open, and then the second tool container system is stacked on the first tool container system. However, when the second tool container system is stacked on the first tool container system, there may be a situation where the second tool container system knocks down the first locking buckle and flips it onto the lid, and there may also be a situation where the user forgets to flip out the first locking buckle and directly stacks the second tool container system on the first tool container system. In both cases, the user needs to remove the second tool container system, flip out the first locking buckle, and then move the second tool container system onto the first tool container system. This process is inconvenient to operate and time-consuming and laborious.

[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0054] As Figure 1 shown, the tool container system provided by the embodiment of the present application includes a first tool container 100 and a second tool container 200 that can be stacked. Among them, the first tool container 100 is provided with at least two first locking parts 110. Among all the first locking parts 110, at least one first locking part 110 is arranged on the first side 150 of the first tool container 100, and at least one first locking part 110 is arranged on the second side 160 of the first tool container 100. The first side 150 and the second side 160 are two opposite sides of the first tool container 100. Exemplarily, one first locking part 110 is arranged on the first side 150 of the first tool container 100, and one first locking part 110 is arranged on the second side 160 of the first tool container 100. In any one of the first locking parts 110, the first locking part 110 is slidably connected to the first tool container 100, and the first locking part 110 can at least slide between a storage position and a locking position.

[0055] In this embodiment, the second tool container 200 is provided with at least two second locking portions 210. The number of the second locking portions 210 is the same as that of the first locking portions 110 and they correspond to each other one by one. In any corresponding first locking portion 110 and second locking portion 210, the first locking portion 110 is configured to be able to slide out from the storage position when the second tool container 200 is stacked on the first tool container 100, or when the first tool container 100 is stacked on the second tool container 200. And when the first locking portion 110 moves to at least the locking position, it can flip to one side of the second tool container 200 and can flip to the second locking portion 210, and the first locking portion 110 and the second locking portion 210 cooperate to lock the first tool container 100 and the second tool container 200 together. That is to say, the first locking portion 110 of the tool container in the tool container system provided by the embodiment of the present application is stored in the first tool container 100 at the storage position. When the two tool containers need to be stacked, the two tool containers can be directly stacked, and then the first locking portion 110 is pulled, so that the first locking portion 110 slides out from the storage position, and then flips to the side where the second tool container 200 is located, flips the first locking portion 110 to the second locking portion 210, and cooperates with the second locking portion 210 to lock. The first locking portion 110 and the second locking portion 210 cooperate to lock, so that the stacked first tool container 100 and second tool container 200 are locked together. When the tool containers of the tool container system provided by the embodiment of the present application are stacked, there is no need to operate on the first locking portion 110 in advance, nor to worry about the problem that the first locking portion 110 is knocked down during the stacking process of the tool containers, which affects the stacking operation of the tool containers. The operation is convenient and fast.

[0056] Please continue to refer to Figure 1 , in the embodiment of the present application, the second tool container 200 and the first tool container 100 have the same structure. That is to say, the second locking portion 210 is also provided on the first tool container 100, and the first locking portion 110 is also provided on the second tool container 200.

[0057] It should be noted that the fact that the second tool container 200 and the first tool container 100 have the same structure means that the shapes, sizes, etc. of the first tool container 100 and the second tool container 200 are the same, that is, the second tool container 200 and the first tool container 100 are exactly the same.

[0058] It should be noted that the tool container system provided in the embodiments of the present application may further include a third tool container, a fourth tool container, etc. The first tool container 100, the second tool container 200, the third tool container, and the fourth tool container can be stacked together. The first tool container 100, the second tool container 200, the third tool container, and the fourth tool container are all tool containers with the same structure. That is, the tool container system provided in the embodiments of the present application includes multiple (including two) first tool containers 100. The multiple tool containers can be stacked, and two adjacent tool containers can be locked together through the cooperation of the first locking portion 110 and the second locking portion 210.

[0059] As Figure 1 , Figure 2 and Figure 3 shown, the first tool container 100 is provided with at least two mounting grooves 120. The number of the mounting grooves 120 is the same as the number of the first locking portions 110 and they correspond one by one. In the corresponding first locking portion 110 and mounting groove 120, the first locking portion 110 is slidably mounted in the mounting groove 120. When the first locking portion 110 is in the storage position, the first locking portion 110 is sunk in the mounting groove 120. This setting facilitates the pulling operation of the first locking portion 110, and when the first tool container 100 and the second tool container 200 are stacked, the first locking portion 110 is sunk in the mounting groove 120, which can prevent the pulling of the first locking portion 110 from being interfered.

[0060] In this embodiment, both the first tool container 100 and the second tool container 200 include a box body 130 and a cover body 140 for covering or opening the box body 130. Each mounting groove 120 is provided on the cover body 140, and each second locking portion 210 is provided on the box body 130. When the first tool container 100 and the second tool container 200 are stacked, the second tool container 200 is stacked on the first tool container 100.

[0061] As Figure 3As shown, the installation groove 120 is provided at the edge of the cover body 140, and the installation groove 120 communicates with the side surface of the cover body 140. When the first locking portion 110 slides out from the storage position to the locking position, a part of the first locking portion 110 extends out of the installation groove 120 from the through opening of the installation groove 120 and the side surface of the cover body 140. That is to say, when the first locking portion 110 is in the storage position, the first locking portion 110 is sunk in the installation groove 120. When the second tool container 200 is stacked on the first tool container 100 and the first locking portion 110 and the second locking portion 210 cooperate to lock the second tool container 200 and the first tool container 100, the first locking portion 110 is pulled outwards from the through opening of the installation groove 120 and the side surface of the cover body 140 to pull out the first locking portion 110, and the first locking portion 110 is pulled to the locking position. Then, the first locking portion 110 is flipped towards one side of the second tool container 200 to flip the first locking portion 110 to the second locking portion 210, and the second locking portion 210 and the first locking portion 110 cooperate to lock, thereby locking the second tool container 200 on the first tool container 100.

[0062] As Figure 3 and Figure 4 shown, both side walls of the installation groove 120 in the first direction (such as Figure 3 the X direction in

[0063] Figure 3 are provided with sliding grooves 121. One end of the sliding groove 121 close to the edge of the cover body 140 has a blocking side wall. Both sides of the first locking portion 110 in the first direction are provided with sliding portions 111, and the two sliding portions 111 are respectively placed in the two sliding grooves 121, and the first locking portion 110 slides back and forth along the length direction of the sliding groove 121. The blocking side wall is used to limit the position of the sliding end of the first locking portion 110 to prevent the first locking portion 110 from sliding out of the sliding groove 121. Exemplarily, when the first locking portion 110 slides to the blocking side wall, the first locking portion 110 is in the locking position.

[0063] To increase the firmness of the engagement between the first locking portion 110 and the second locking portion 210 and avoid accidental unlocking, a limiting groove 122 is provided at one end of the sliding groove 121 close to the edge of the cover body 140. The limiting groove 122 is located on the side of the sliding groove 121 close to the top surface of the cover body 140 and is in communication with the sliding groove 121. The limiting groove 122 is configured such that when the first locking portion 110 and the second locking portion 210 cooperate to lock the first tool container 100 and the second tool container 200, at least a part of the sliding portion 111 is located within the limiting groove 122. That is to say, after the first locking portion 110 moves to the locking position and is turned up and engaged with the second locking portion 210, at least a part of the sliding portion 111 of the first locking portion 110 moves from the sliding groove 121 to the limiting groove 122. The limiting groove 122 restricts the position of the sliding portion 111, such that the sliding portion 111 cannot move along the length direction of the sliding groove 121. Thereby, after the first locking portion 110 and the second locking portion 210 are engaged, the situation where the first locking portion 110 and the second locking portion 210 are unlocked due to the movement of the first locking portion 110 is avoided.

[0064] Please continue to refer to Figure 3 , to facilitate the installation of the sliding portion 111 of the first locking portion 110 in the sliding groove 121, at one end of the installation groove 120 away from the edge of the cover body 140, relief grooves 123 are provided on both side walls of the installation groove 120 in the first direction. The relief grooves 123 penetrate through the sliding groove 121 and the top surface of the cover body 140. The relief grooves 123 are configured to allow the sliding portion 111 to be installed in the sliding groove 121. That is to say, the two sliding portions 111 of the first locking portion 110 are respectively installed in the sliding groove 121 through the relief grooves 123 on both side walls of the installation groove 120. This setting facilitates the installation of the first locking portion 110.

[0065] As Figure 3 and Figure 4 shown, the installation groove 120 includes a left installation groove 124 and a right installation groove 125. The left installation groove 124 and the right installation groove 125 are spaced apart in the first direction, and sliding grooves 121 are provided on both side walls of the left installation groove 124 and the right installation groove 125 in the first direction.

[0066] The first locking portion 110 includes a left mounting portion 112, a right mounting portion 113, and a connecting portion 114 connecting the left mounting portion 112 and the right mounting portion 113. Sliding portions 111 are provided on both sides of the left mounting portion 112 and the right mounting portion 113 along the first direction. The left mounting portion 112 is slidably mounted in the left mounting groove 124, and the right mounting portion 113 is slidably mounted in the right mounting groove 125. That is to say, the two sliding portions 111 of the left mounting portion 112 are respectively mounted in the two sliding grooves 121 of the left mounting groove 124, and the two sliding portions 111 of the right mounting portion 113 are respectively mounted in the two sliding grooves 121 of the right mounting groove 125. This setting can increase the connection strength between the first locking portion 110 and the first tool container 100. When the first locking portion 110 and the second locking portion 210 are locked together, the first locking portion 110 is connected to the first tool container 100 through the two sliding portions 111 of the left mounting portion 112 and the two sliding portions 111 of the right mounting portion 113. The strength borne by the four sliding portions 111 is relatively greater than the strength borne by the two sliding portions 111.

[0067] It should be noted that in some embodiments of the present application, the mounting groove 120 can be a single groove. That is to say, the first locking portion 110 only has sliding portions 111 on the opposite sides, and the two sliding portions 111 are mounted in the sliding grooves 121 on the opposite side walls of the mounting groove 120. Of course, the structure of the mounting groove 120 can also be Figure 3 the double groove shown.

[0068] As Figure 1 、 Figure 4 and Figure 5 shown, the second locking portion 210 is a clamping plate 211 connected to the box body 130. Hook portions 115 are provided on both the left mounting portion 112 and the right mounting portion 113. When the first locking portion 110 and the second locking portion 210 cooperate to lock the first tool container 100 and the second tool container 200, the hook portions 115 of the left mounting portion 112 and the hook portions 115 of the right mounting portion 113 are both clamped to the clamping plate 211.

[0069] Exemplarily, a groove 220 is provided at the bottom of the box body 130 corresponding to the first locking portion 110. The clamping plate 211 is disposed in the groove 220, and two ends of the clamping plate 211 are respectively connected to opposite side walls of the groove 220. A reinforcing rib 212 is connected between the middle of the clamping plate 211 and the bottom surface of the groove 220. The hook 115 of the left mounting portion 112 is clamped with the clamping plate 211 on one side of the reinforcing rib 212, and the hook 115 of the right mounting portion 113 is clamped with the clamping plate 211 on the other side of the reinforcing rib 212. This setting can increase the strength of the clamping plate 211. Moreover, the first locking portion 110 is divided into a left mounting portion 112 and a right mounting portion 113, which are respectively clamped on both sides of the area where the reinforcing rib 212 of the clamping plate 211 is provided. This setting enables the reinforcing rib 212 of the clamping plate 211 to extend to the top of the clamping plate 211 without interfering with the clamping of the first locking portion 110 and the clamping plate 211, increases the strength of the clamping plate 211, increases the firmness of the clamping between the first locking portion 110 and the clamping plate 211, and avoids the problem of poor clamping fit between the first locking portion 110 and the clamping plate 211 caused by deformation of the clamping plate 211.

[0070] In some embodiments of the present application, as Figure 4 shown, the end of the first locking portion 110 that is slidably connected to the mounting groove 120 is provided with an arc-shaped structure. A support member 116 is provided on the side of the first locking portion 110 facing the middle of the first tool container 100. When the first locking portion 110 is turned upward to be substantially vertical, the support member 116 blocks the first locking portion 110 from continuing to turn and prompts the first locking portion 110 to fall back. This setting can avoid the problem that the first locking portion 110 forms a substantially vertical or turns to the upper part of the first tool container 100, thereby affecting the operation of stacking the second tool container 200 on the first tool container 100.

[0071] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the invention disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common knowledge or conventional technical means in the technical field not disclosed in the present application.
