[0036] Embodiment 1. Please refer to Figure 1-2 , a toolbox that is convenient to use, including a tool box 1 and a frame-shaped plate rack 2 with through front and rear end faces. The tool box 1 is placed inside the frame-shaped plate rack 2, and the number of tool boxes 1 is at least one; on the side walls at the front and rear ends of the frame-shaped plate rack 2, there are rotatably fixed attachment seats 3, and a first rotary lock 4 passes through the attachment seats 3, and the first rotary lock 4 elastically abuts against the end face of the tool box 1 correspondingly.

[0037] In this embodiment, the number of tool boxes 1 can be one, that is, the overall device is in the frame plate rack 2, or it can be multiple, and at least one size is set.

[0038] Figure 4 As shown in the figure, the number of tool boxes 1 is 4. The height of each tool box 1 is 50 mm, and they are stacked vertically inside the frame plate rack 1. And on both the left and right sides of each tool box 1, there are attachment seats 3 and first rotary locks 4. The first rotary lock 4 can abut against the end face of the tool box 1 through the rotation of the attachment seat 3 for positioning. As Figure 2 shown, at this time, the first rotary lock 4 is in a horizontal state and abuts against the end face of the tool box 1. As Figure 1 shown in the figure, when the first rotary lock 4 is in a vertical state, the tool box 1 is not fixed, so it can be pulled outwards.

[0039] As Figure 5 shown, the number of tool boxes 1 is 3 in total, with 1 having a height of 101 mm and the other two having a height of 50 mm. The three tool boxes 1 shown in the figure are stacked vertically, and the relative positions of the tool boxes 1 can be freely adjusted.

[0040] As Figure 6 shown, the number of tool boxes 1 is 2 in total, and their heights are both 101 mm, and they can be stacked vertically.

[0041] As Figure 7 shown, the number of tool boxes 1 is 2, one of which has a height of 151.5 mm and the other has a height of 50 mm, and they can be stacked vertically.

[0042] Except for the difference in height of the above-mentioned tool boxes 1, due to the influence of the draft angle during production, as the height of the tool box 1 increases from low to high, the length increases by about 2 mm in sequence.

[0043] Preferably, in this embodiment, there can be two tool boxes 1 at the same height. The two tool boxes 1 are at the same height level and are stacked together above the tool box 1 at the bottom. The surfaces of the two tool boxes 1 adjacent to the end face of the frame plate rack 2 are fixed through the attachment seats 3 and the first rotary locks 4. It can be seen that the size and height of the tool box 1 in this embodiment can be adjusted so that the overall height of the stacked tool boxes 1 is approximately equal to the internal height of the frame plate rack 2, and the objects inside the tool box 1 will not fall out from the gap between the tool box 1 and the inner wall of the frame plate rack 2 when the toolbox overturns.

[0044] Embodiment 2: At least one wedge-shaped notch 6 is provided on the front and rear end faces of the bottom plate of the frame plate rack 2. A first mounting seat 7 or a second mounting seat 8 is connected in the wedge-shaped notch 6. And a guide rail 9 is provided at the bottom of the frame plate rack 2. A connecting frame 10 fixed on the vehicle is provided between the surfaces of the first mounting seat 7 or the second mounting seat 8 opposite to the guide rail 9, and they are detachably and fixedly connected to the connecting frame 10.

[0045] like Figure 4 As shown, the tool box 1 can be pulled out from the frame plate frame 2. In addition, in the present embodiment, the guide rail 9 and the connecting frame 10 structure are further added, the guide rail 9 and the connecting frame 10 are vertically and fixedly connected, and the connecting frame 10 and the guide rail 9 are fixed on the vehicle.

[0046] The vehicle in this embodiment is preferably a truck with a large transport capacity, that is, the connecting frame 10 and the guide rail 9 in this embodiment can be arranged in multiple layers in parallel, and the connecting frames 10 or guide rails 9 between each layer are connected by a vertical support frame, that is, a grid shape is formed, and the space between the upper and lower layers just accommodates the frame plate frame 2, and the frame plate frame 2 is fixed on the connecting frame 10 through the first mounting seat 7 and the second mounting seat 8. When the tool box needs to be taken out, it is only necessary to disassemble any of the first mounting seat 7 or the second mounting seat 8 at the front and rear ends of the tool box, and the tool box can be detached from the vehicle, which is simple and convenient to operate.

[0047] Example 3, see Figure 3 The first rotary lock 4 includes a screw 401 passing through the attachment 3, the end of the screw 401 is sleeved with a first positioning sleeve 402 abutting against the end surface of the tool box 1, and a first spring 403 sleeved on the outer wall of the screw 401 is provided between the attachment 3 and the first positioning sleeve 402.

[0048] This embodiment further optimizes the structure of the first rotary lock 4, that is, when the attachment 3 rotates to the horizontal state, the screw 401 is screwed, and the screw 401 is threadedly connected with the attachment 3, so that the screw 401 gradually approaches the end face of the tool box 1. The end of the screw 401 is sleeved with a first positioning sleeve 402, that is, a blind hole is provided in the first positioning sleeve 402, and the end of the screw 401 penetrates into the blind hole and matches with the gap of the blind hole. When the screw 401 is screwed and gradually approaches the end face of the tool box 1, the first positioning sleeve 402 is driven to press against the surface of the tool box 1.

[0049] When it is necessary to release the first rotary lock 4 from fixing the tool box 1, the screw 401 is turned in the opposite direction to move the first positioning sleeve 402 away from the end surface of the tool box 1. At this time, the first spring 403 is in a compressed state, and then the attachment 3 is rotated to separate the first rotary lock 4 from the surface of the tool box 1.

[0050] Furthermore, the front and rear end surfaces of the tool box 1 are provided with avoidance openings 11 at the abutting positions corresponding to the first positioning sleeve 402. The avoidance openings 11 make the connection between the first rotary lock 4 and the tool box 1 more beautiful and facilitate the first rotary lock 4 to position the tool box 1.

[0051] Further, see Figure 3, brackets 12 are fixed on the left and right inner side walls of the frame - type plate frame 2. The attachment seat 3 is rotatably fixed on the end face of the bracket 12 through a screw 18. A bushing 19 is connected between the screw 18 and the attachment seat 3. One axial end face of the bushing 19 abuts against the end face of the bracket 12, and the other axial end face is located in front of the end face of the attachment seat 3; positioning grooves 13 for accommodating the first positioning sleeve 402 are provided on the front and rear end faces of the bracket 12 corresponding to the rotation of the attachment seat 3. The attachment seat 3 is fixed on the bracket 12 through the screw 18, and the bracket 12 is fixed inside the frame - type plate frame 2, so the attachment seat 3 is also located inside the frame - type plate frame 2, which can avoid forming a protruding object outside the frame - type plate frame 2 and causing an obstacle to the placement of the toolbox. The positioning groove 13 is used to store the first positioning sleeve 402 and position the first rotary lock 4. Due to the existence of the bushing 19, the attachment seat 3 can rotate around the screw 18 by itself, and the axial end face of the bushing 19 is located about 2 mm in front of the end face of the attachment seat 3, which is used to prevent the screw 18 from pressing against the attachment seat 3.

[0052] Example 4, see Figure 8-9 , the first mounting seat 7 is wedged into the wedge - shaped notch 6 and fixedly connected to the connecting frame 10.

[0053] The first mounting seat 7 is arranged on the front or rear side of the frame - type plate frame 2. The first mounting seat 7 is wedged into the wedge - shaped notch 6 and fixedly connected to the connecting frame 10. A buffer cotton 16, preferably a self - adhesive foam, is adhered to the surface of the first mounting seat 7 that fits the wedge - shaped notch 6. The connecting frame 10 is preferably a profile bracket. The first mounting seat 7 is fixed to the profile bracket through bolts and T - nuts. The bolts and T - nuts can also be separated along the profile bracket. When the first mounting seat 7 needs to be disassembled, only the bolts need to be loosened.

[0054] Furthermore, as Figure 10-12 shown, it further includes a wedge - shaped positioning block 14. The wedge - shaped positioning block 14 is wedged into the wedge - shaped notch 6 and is relatively fixed to the second mounting seat 8 through a connecting rod 17; the second mounting seat 8 and the connecting frame 10 are rotatably fixed through a second rotary lock 5. The second rotary lock 5 includes a connecting seat 504, a base block 505, and a pull rod 501 passing through the second mounting seat 8 and the connecting seat 504. One end of the pull rod 501 is fixed with a second positioning sleeve 502. The second positioning sleeve 502 is a prism and is located inside the connecting frame 10. The connecting seat 504 is sleeved inside the base block 505 and fixed to the base block 505. The base block 505 is fixed on the connecting frame 10. A second spring 503 sleeved on the outer side wall of the pull rod 501 is provided between the second mounting seat 8 and the second positioning sleeve 502.

[0055] The connecting frame 10 is preferably a profile bracket. The second positioning sleeve 502 is a prism, and the side wall of the pull rod 501 that cooperates with the second mounting seat 8 also has an edge to prevent the second mounting seat 8 from rotating around the pull rod 501 by itself. When the second mounting seat 8 is fastened to the frame - type plate frame 2, Figure 10As shown in the figure, the distance a between the wedge-shaped positioning block 14 and the second mounting seat 8 is relatively large. After the connecting rod 17 is threadedly connected to the second mounting seat 8, the end face contacts the wedge-shaped positioning block 14, and the connecting rod 17 and the wedge-shaped positioning block 14 are fixed by a bolt passing through the wedge-shaped positioning block 14. The connecting rod 17 is rotated by screwing to lock the wedge-shaped positioning block 14 onto the positioning notch 6. And at this time, the distance b between the pull rod 501 and the second mounting seat 8 is also relatively large. The pull rod 501 is stretched outward, and the pull rod makes the second positioning sleeve 502 snap into the side wall notch of the profile bracket. Since the second positioning sleeve 502 is a prism, it snaps into the notch of the profile bracket to lock the second mounting seat 8 from rotating. At this time, the second spring 503 is in a natural state.

[0056] As Figure 11 shown, when the second mounting seat 8 is unlocked from the frame-shaped plate rack 2, first, the pull rod 501 approaches the connecting frame 10, and the second positioning sleeve 502 is pressed against the inside of the side wall notch of the profile bracket. The cylindrical body of the pull rod 501 is fitted and connected to the side wall notch of the profile bracket, enabling the pull rod 501 to rotate freely. At this time, the distance b between the pull rod 501 and the second mounting seat 8 is relatively small. Then, the connecting rod 17 fixed to the wedge-shaped positioning block 14 is rotated by threading. The connecting rod 17 drives the wedge-shaped positioning block 14 to move outward, causing the wedge-shaped positioning block 14 to disengage from the wedge-shaped notch 6. At this time, the value of a is small. Then, the second mounting seat 8 is rotated 90° as a whole around the pull rod 501, and the second mounting seat 8 can be disengaged from the connection with the frame-shaped plate rack 2, realizing the overall freedom of the toolbox.

[0057] As Figure 9 shown, rollers 15 are evenly distributed along the front-back length direction on the guide rail 9, and the rollers 15 are rotatably fixed on the side wall of the guide rail 9. Then, the bottom surface of the frame-shaped plate rack 2 is tangent to the side surface of the roller 15. When the frame-shaped plate rack 2 is pulled out as a whole, the roller 15 rolls, enabling the toolbox to be easily pulled out and put in, saving effort and improving the efficiency of putting in and taking out.

[0058] In Embodiment 5, identification tags are fixed on the front and rear end faces of the tool box 1. The identification tags list the tool categories and details included in the tool box 1, which can facilitate finding the required tools quickly. The identification tags can be engraved or attached or drawn on the surface of the tool box 1, or can be detachably connected to the tool box 1. For example, a transparent storage slot is provided on the surface of the tool box 1, and the identification tag is placed therein.

[0059] In this technical solution, the size of the frame-shaped plate rack is fixed, and the size and quantity of the tool boxes can be adjusted to meet different carrying requirements. The two end faces of the tool boxes are abutted through the first rotary lock penetrating the attachment base for fixing the tool boxes. When it is necessary to take out the items in the tool boxes, only need to turn the attachment base to make the first rotary lock no longer abut the end face of the tool box, and the double-sided drawing of the tool boxes can be realized. When the tool box is in the vehicle-mounted state, it is detachably fixed through the first mounting base, the second mounting base and the connecting frame, with simple structure, convenient operation and high practicability.

[0060] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0061] Therefore, the above description is only the preferred embodiment of the present application, and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
