Description

Technical Field

[0001] The utility model belongs to the technical field of tool boxes, in particular to a tool box for engineering cost. Background Art

[0002] The engineering cost toolbox is a tool specially designed to provide convenient services for engineering cost workers. It can help users quickly calculate costs, manage data, etc. The current toolbox will take out the internal tools for use when in use. However, most of the surfaces of the toolbox do not have expansion space, and it is difficult to place the tools taken out in order, which leads to the tools being easily lost when placed randomly, thereby increasing unnecessary processing costs. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a tool box for engineering cost estimation, which solves the problem that most of the surface of the tool box does not have expansion space, making it difficult to place the tools taken out in order, resulting in the tools being easily lost when placed randomly, thereby increasing unnecessary processing costs.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool box for engineering cost, comprising a box body, four sleeve plates are connected outside the box body, guide rods are rotatably connected inside the sleeve plates, expansion plates are connected outside the guide rods, a box cover is provided on the box body, four support plates are provided outside the box body, fixing rods are rotatably connected on both sides of the expansion plates, connecting plates are rotatably connected outside the fixing rods, limiting holes are provided on both sides of the expansion plates, positioning rods are slidably connected inside the connecting plates, limiting disks 1 and 2 are connected outside the positioning rods, and a spring is connected outside the positioning rods.

[0005] As a further solution of the utility model: the positioning rod is clamped in the supporting plate, and the second limiting plate is connected to the connecting plate through a spring.

[0006] As a further solution of the utility model: four storage slots are opened outside the box body, a rotating rod is connected inside the support plate, and the rotating rod is rotatably connected outside the box body.

[0007] As a further solution of the utility model: a positioning groove is provided under the expansion plate, and a groove is provided outside the connecting plate.

[0008] As a further solution of the utility model: the support plate is clamped in the storage groove, and the positioning rod is clamped in the limiting hole.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. The tool box for engineering cost is provided with an expansion plate, a connecting plate, a supporting plate, a positioning rod, a limiting plate 2 and a spring. The expansion plate rotates around the guide rod and then pulls the positioning rod. After the positioning rod is separated from the limiting hole, the connecting plate rotates around the fixed rod. When the positioning rod is squeezed, the limiting plate 2 on the surface causes the spring to deform. When the connecting plate and the supporting plate coincide with each other, the positioning rod is released, and the positioning rod after reset is clamped in the supporting plate. The expansion plate can be unfolded on the surface of the box through the cooperation between the supporting plate, the positioning rod and the spring, and the utensils taken can be placed through the expansion plate to avoid the loss of the utensils during the placing process, thereby ensuring the adaptability of the tool box.

[0011] 2. The engineering cost tool box is provided with a rotating rod, a storage slot and a positioning slot. When the tool box is not in use, a thrust can be applied to the support plate, and the support plate will rotate around the rotating rod. After the support plate rotates, it will be snapped into the storage slot, so that the support plate can realize the storage function and avoid deformation of the support plate caused by impact during transportation of the tool box.

DETAILED DESCRIPTION

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, the utility model provides a technical solution: a tool box for engineering cost, including a box body 1, four sleeve plates 3 are connected to the outside of the box body 1, guide rods 4 are rotatably connected inside the sleeve plates 3, and expansion plates 5 are connected to the outside of the guide rods 4, a box cover 2 is provided on the box body 1, four support plates 8 are provided outside the box body 1, both sides of the expansion plates 5 are rotatably connected to fixed rods 6, and connecting plates 7 are rotatably connected to the outside of the fixed rods 6;

[0018] Four storage slots 15 are provided outside the box body 1, and a rotating rod 14 is connected inside the support plate 8. The rotating rod 14 is rotatably connected to the outside of the box body 1. By providing the storage slots 15, when the support plate 8 is rotated, it will be clamped in the storage slots 15, so that the storage slots 15 play a certain auxiliary role for the support plate 8, so as to prevent the support plate 8 from being exposed to the outside and damaged, and can be unfolded when in use;

[0019] Limiting holes 9 are provided on both sides of the expansion plate 5, and a positioning rod 10 is slidably connected in the connecting plate 7. A positioning groove 17 is provided under the expansion plate 5, and a groove 16 is provided outside the connecting plate 7. The support plate 8 is clamped in the storage groove 15, and the positioning rod 10 is clamped in the limiting hole 9. By setting the limiting hole 9, when the expansion plate 5 is not in use, the positioning rod 10 in the connecting plate 7 will be clamped with the limiting hole 9, so that the connecting plate 7 can be fixed to the side of the expansion plate 5 when not in use, so as to prevent the connecting plate 7 from shaking on the side of the expansion plate 5;

[0020] The positioning rod 10 is externally connected with a limiting plate 11 and a limiting plate 2 12, and a spring 13 is externally connected to the positioning rod 10. By providing the limiting plate 11 and the limiting plate 2 12, when the positioning rod 10 slides in the connecting plate 7, the limiting plate 11 and the limiting plate 2 12 will contact the connecting plate 7 respectively, so that the limiting plate 11 and the limiting plate 2 12 play a certain positioning role in the movement of the positioning rod 10, thereby preventing the positioning rod 10 from falling off from the connecting plate 7 when moving;

[0021] The positioning rod 10 is clamped in the support plate 8, and the limit plate 12 is connected to the connecting plate 7 through the spring 13. By setting the spring 13, when the positioning rod 10 is subjected to thrust or tension, the positioning rod 10 will drive the spring 13 to deform when it moves, so that the spring 13 plays a certain supporting role in the movement of the positioning rod 10. When the positioning rod 10 loses resistance, it will be reset by the spring 13.

[0022] The working principle of the utility model is:

[0023] When the tool box is in use, the expansion plate 5 can be rotated around the guide rod 4. When the expansion plate 5 is rotated to the appropriate position, the positioning rod 10 is pulled. After the positioning rod 10 is disengaged from the limiting hole 9, the connecting plate 7 will rotate around the fixing rod 6. Then the support plate 8 is taken out from the storage groove 15. The support plate 8 will rotate around the rotating rod 14. When the support plate 8 and the box body 1 are in a vertical state, the positioning rod 10 is squeezed. When the positioning rod 10 slides in the connecting plate 7, the limiting plate 12 on the surface will cause the spring 13 to deform. When the connecting plate 7 and the support plate 8 coincide with each other, the positioning rod 10 is released. The positioning rod 10 will be reset by the action of the spring 13, and the reset positioning rod 10 will be clamped in the support plate 8.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 or an electrical connection; it can be a direct connection, or it can be an indirect connection 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 by specific circumstances.

[0025] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
