[0035] This utility model addresses the problem of current railway operation toolboxes being bulky and inconvenient to carry, by providing a portable toolbox for railway use, such as... Figures 1-5 As shown, it includes a first box panel 1, a second box panel 2, a third box panel 3, and a bottom panel 4, wherein:

[0036] The first box panel 1 and the second box panel 2 are arranged opposite to each other, and their two sides are connected by a number of third box panels 3;

[0037] The third box panel 3 is rotatably connected to the first box panel 1, the third box panel 3 is rotatably connected to the second box panel 2, and the connected third box panels 3, so that the third box panel 3 can be folded inward between the first box panel 1 and the second box panel 2.

[0038] The base plate 4 can rotate between the first box plate 1 and the second box plate 2. The base plate 4 is provided with a limiting device 5, which is used to fix the base plate 4 to the first box plate 1 or the second box plate 2.

[0039] With the above settings, as Figure 6 As shown, the bottom plate 4 can be folded between the first box plate 1 and the second box plate 2, and then the first box plate 1 and the second box plate 2 can be squeezed to make the third box plate 3 fold inward between the first box plate 1 and the second box plate 2, or more precisely, folded between the bottom plate 4 and the second box plate 2, thereby greatly reducing the volume of the work box and making it easier to carry.

[0040] In the preferred embodiment of this utility model, such as Figure 1 , Figure 4 As shown, the third box panel 3 is connected to the first box panel 1, the third box panel 3 is connected to the second box panel 2, and the connected third box panels 3 are all connected by hinges. Other similar structures can also be used for connection.

[0041] More preferably, the first box panel 1 and the second box panel 2 are connected by four third box panels 3 of equal width, so that the third box panels 3 can be completely folded in half to minimize the thickness after folding.

[0042] In a preferred embodiment of this utility model, the bottom plate 4 is connected to the lower end of the first box plate 1 by a hinge. A limiting device 5 is provided on the bottom plate 4 near the second box plate 2. More specifically, the limiting device 5 is a spring pin. The lower end of the second box plate 2 is provided with a first limiting hole 6 that cooperates with the spring pin. When the spring pin is inserted into the first limiting hole 6, the bottom plate 4 can be fixed relative to the first box plate 1 and the second box plate 2, thereby keeping the toolbox in an unfolded state.

[0043] In a preferred embodiment of this utility model, a spring self-locking pin 7 is provided on one or both sides of the second box plate 2, and a second limiting hole 8 is provided on one or both sides of the first box plate 1. When the third box plate 3 is folded inward between the first box plate 1 and the second box plate 2, the limiting part of the spring self-locking pin 7 can be inserted into the second limiting hole 8, thereby locking the first box plate 1 and the second box plate 2 and preventing the toolbox from being accidentally unfolded when carried. When it is necessary to unfold, the spring self-locking pin 7 can be pulled outward.

[0044] In a preferred embodiment of this utility model, the top of the first box plate 1 is provided with two or more hooks 9 so as to hang it on the outside of the railing of the work frame, thereby not occupying the internal space of the work frame.

[0045] In a preferred embodiment of this utility model, a handle 10 is provided on one end of the base plate 4 near the limiting device 5. The handle 10 is rotatably connected to the base plate 4. When the toolbox needs to be folded, the spring pin is pulled out and the handle 10 is lifted to fold the base plate 4 to a position that fits against the first box plate 1.

[0046] The portable toolbox for railways provided in this application, when in the unfolded state, has a spring pin on the base plate 4 inserted into the first limiting hole 6, which fixes the base plate 4 relative to the first box plate 1 and the second box plate 2. At this time, the first box plate 1 and the second box plate 2 are blocked by the base plate 4 and cannot get close, and the third box plate 3 is also kept in the unfolded state and cannot be folded inward, so that the toolbox is in the box state. It can be hung on the work frame by the hook 9 and used to place tools.

[0047] When the toolbox needs to be folded up for easy carrying, pull out the spring pin on the base plate 4, pull the handle 10 to fold the base plate 4 towards the first box plate 1 until it fits against the first box plate 1, and then squeeze the first box plate 1 and the second box plate 2 to fold the third box plate 3 inward between the first box plate 1 and the second box plate 2. More precisely, after folding inward, the third box plate 3 is located between the base plate 4 and the second box plate 2. After being fully folded, the limiting part of the spring self-locking pin 7 is exactly aligned with the second limiting hole 8 and is inserted, thereby locking the first box plate 1 and the second box plate 2 and preventing the toolbox from being accidentally unfolded when carried.

[0048] In summary:

[0049] This application provides a portable toolbox for railway use, which can be easily and quickly switched between a folded and unfolded state. It can be used to temporarily place tools on the work frame during high-altitude operations, and is easy to fold and carry, making it very suitable for outdoor operations in railway transportation and other fields.
