Description

Technical Field

[0001] This utility model relates to the technical field of fire protection engineering tool storage equipment, specifically, to a toolbox for fire protection engineering installation. Background Technology

[0002] During fire protection engineering installation, various tools and equipment are required, such as wrenches, screwdrivers, pipe wrenches, and electric drills. The storage and management of these tools and equipment has always been a challenge. Traditional toolboxes have simple structures and limited functions, failing to meet the storage and management needs of fire protection engineering installation. For example, storing tools of different specifications and types easily leads to confusion and loss, affecting work efficiency and construction quality. Furthermore, for tools with multiple detachable working ends, traditional toolboxes are prone to losing these working ends. Therefore, a new type of toolbox for fire protection engineering installation has been designed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a toolbox for fire protection engineering installation. Through the cooperation of limit rod and limit block, the drawer is stably limited. The limit hole and inner sleeve design on the first placement plate, as well as the various brackets and support grooves on the first placement surface, facilitate the adaptation to the situation where a tool has multiple detachable and replaceable working heads.

[0004] A toolbox for fire protection engineering installation includes an upper box and a lower box. The upper box is fixed to the upper side of the lower box. One bottom side of the upper box is a first placement surface. The other two sides of the lower box are fixedly connected to a first placement plate. The upper side of the first placement plate is higher than the first placement surface. The first placement plate and the first placement surface form a stepped support surface.

[0005] The lower box has an opening on one side, and a drawer is installed in the opening. The drawer and the lower box are slidably connected. Both the upper box and the lower box are connected to a limiting component.

[0006] Furthermore, the limiting component includes a limiting rod, which is fixed to the lower front side of one side of the upper box. The lower middle position of the limiting block is rotatably connected to the front side of one side of the drawer. A limiting slot is provided on the limiting block. The limiting slot is an arc-shaped slot, and one end of the limiting slot is open. When the other end of the limiting slot contacts the limiting rod, the limiting block will lock the limiting post without disengaging from the limiting post due to the arc shape of the limiting slot.

[0007] Furthermore, the surface of the limiting post is a rubber layer, a stop block is fixed at the outer end of the limiting post, and a knob is fixedly connected to the middle of the limiting block.

[0008] Furthermore, the upper housing is hinged to the housing cover, the housing cover is screwed to the positioning bolt, and the upper housing has a threaded hole corresponding to the position of the positioning bolt, and the bolt is screwed to the threaded hole.

[0009] Furthermore, the first placement plate has a plurality of evenly arranged limiting holes, and an inner sleeve is fixedly installed in each of the limiting holes.

[0010] Furthermore, a pair of second brackets and a pair of third brackets are fixedly provided at both ends of the first placement surface, and symmetrical first brackets are also fixedly provided on the first placement surface. A support groove is provided on the first placement surface corresponding to the position of one of the first brackets.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are:

[0012] By combining the limit rod and the limit block, the drawer is stably limited, effectively preventing the drawer from accidentally sliding out during transportation or use, thus enhancing the safety and reliability of the toolbox. The rubber layer design on the surface of the limit rod not only increases the friction between the limit rod and the limit block, making the limiting effect more stable, but also plays a certain role in cushioning.

[0013] The hinged lid and screw-on positioning bolts on the upper body make opening and closing the lid very convenient. At the same time, the positioning bolts ensure the stability of the lid when closed, preventing tools from falling or being damaged due to the lid becoming loose.

[0014] The limiting holes and inner sleeve design on the first placement plate, as well as the various brackets and support grooves on the first placement surface, facilitate the adaptation to situations where a tool has multiple detachable and replaceable working heads.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] A toolbox for fire protection engineering installation includes an upper box 2 and a lower box 12. The upper box 2 is fixed to the upper side of the lower box 12. One bottom side of the upper box 2 is a first placement surface 16. The other two sides of the lower box 12 are fixedly connected to a first placement plate 3. The upper side of the first placement plate 3 is higher than the first placement surface 16. The first placement plate 3 and the first placement surface 16 form a stepped support surface.

[0023] The lower box 12 has an opening on one side, and a drawer 7 is provided in the opening. The drawer 7 and the lower box 12 are slidably connected. Both the upper box 2 and the lower box 12 are connected to a limiting component.

[0024] The stepped support surface formed by the upper box 2 and the lower box 12 allows for the categorized placement of fire-fighting tools of different specifications. The height difference design between the first placement plate 3 and the first placement surface 16 ensures convenient tool access and avoids mutual interference between tools. The sliding connection of the drawer 7 allows for quick access to frequently used small tools, improving work efficiency. At the same time, the limiting component locks the drawer 7 to prevent it from sliding out when not in use.

[0025] The limiting component includes a limiting rod 17, which is fixed to the lower front side of one side of the upper box 2. The lower middle position of the limiting block 10 is rotatably connected to the front side of one side of the drawer 7. A limiting groove 11 is provided on the limiting block 10. The limiting groove 11 is an arc-shaped groove, and one end of the limiting groove 11 is open. When the other end of the limiting groove 11 contacts the limiting rod 17, the limiting block 10 will lock the limiting post without disengaging from the limiting post due to the arc shape of the limiting groove 11.

[0026] The surface of the limiting post is a rubber layer, the outer end of the limiting post is fixed with a stop block 8, and the middle of the limiting block 10 is fixedly connected with a knob 9.

[0027] When drawer 7 needs to be locked, simply rotate the limiting block 10 so that the open end of the limiting slot 11 aligns with the limiting rod 17. Then push the drawer 7 so that the limiting rod 17 enters the limiting slot 11. As the drawer 7 continues to move forward, when the other end of the limiting slot 11 contacts the limiting rod 17, the limiting block 10 will lock the limiting rod 17 due to the superior arc shape of the limiting slot 11. The presence of the rubber layer increases the friction, preventing the limiting block 10 from easily disengaging from the limiting rod 17, thus locking the drawer 7 and preventing it from sliding out when not in use. When drawer 7 needs to be opened, simply rotate the limiting block 10 using the knob 9 to separate the open end of the limiting slot 11 from the limiting rod 17, and the drawer can be pulled out smoothly.

[0028] The principle between the limiting slot 11, the limiting block 10, and the limiting rod 17 is based on the special structural design of the arc-shaped limiting slot 11. When the limiting rod 17 enters the slot, the arc-shaped surface of the slot will form a three-point contact with the surface of the limiting rod 17. Combined with the elastic deformation generated by the rubber layer, static friction is generated on the contact surface to ensure the stability of the drawer 7 in the locked state. The quick unlocking function is realized by rotating the knob 9. When the knob 9 drives the limiting block 10 to rotate, the open end of the limiting slot 11 will disengage from the limiting rod 17 in an involute trajectory.

[0029] The upper housing 2 is hinged to the housing cover 1, the housing cover 1 is screwed with a positioning bolt 18, and the upper housing 2 has a threaded hole 6 at the position corresponding to the positioning bolt 18, and the bolt is screwed into the threaded hole 6.

[0030] The upper housing 2 is screwed on with bolts to enable the opening and closing of the housing cover 1 and the upper housing 2.

[0031] The first placement plate 3 has several evenly arranged limiting holes 4, and an inner sleeve 5 is fixedly installed in each of the limiting holes 4.

[0032] The inner sleeve 5 is a rubber sleeve, which facilitates increasing the friction between parts placed in the limiting hole 4. The design of multiple limiting holes 4 allows for the placement of different parts.

[0033] A pair of second brackets 14 and a pair of third brackets 15 are fixedly installed at both ends of the first placement surface 16. A symmetrical first bracket 13 is also fixedly installed on the first placement surface 16. A support groove 161 is opened on the first placement surface 16 corresponding to the position of one of the first brackets 13.

[0034] It can support tools and is easy to use. Different working heads that are compatible with tools can be placed in the limiting hole 4. By setting the groove on the bracket, the tool can be more securely supported, ensuring that the tool will not shake or slip during placement.

[0035] The lid of the box has an opening that is sealed with a transparent acrylic sheet, making it easy to observe the types of tools inside the box.

[0036] The method of using this utility model is as follows: When using it, first open the box cover 1, and place the fire-fighting tools of different specifications according to their size and shape on the stepped support surface. Larger tools can be placed on the first placement surface 16 and supported stably by the first bracket 13, the second bracket 14 and the third bracket 15. For tools that require specific working heads to be used, the corresponding working head can be inserted into the limiting hole 4 on the first placement plate 3. The rubber material of the inner sleeve 5 can increase the friction between the working head and the working head, ensuring that the working head is placed stably.

[0037] For frequently used small tools, they can be stored in drawer 7. When needed, if drawer 7 is locked, simply rotate the limit block 10 using knob 9 to separate the open end of the limit slot 11 from the limit rod 17, and then pull out drawer 7 to quickly retrieve or store the tools. After use, push drawer 7 back, rotate the limit block 10 to align the open end of the limit slot 11 with the limit rod 17, and push drawer 7 to allow the limit rod 17 to enter the limit slot 11. When the other end of the limit slot 11 contacts the limit rod 17, the limit block 10 will lock the limit rod 17, thus locking drawer 7 and preventing it from sliding out when not in use.

[0038] After all tools have been placed, put the lid 1 on and screw the corresponding threaded hole 6 on the box body 2 with the positioning bolt 18 to close the lid 1 and the upper box body 2.

[0039] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
