Description

Technical Field

[0001] This utility model relates to the field of toolbox technology, and in particular to a portable toolbox for communication maintenance. Background Technology

[0002] Telecommunications maintenance is a crucial link in ensuring the normal operation of communication networks. Its personnel often need to install and repair equipment in various complex environments such as outdoors, base stations, and mountainous areas. To carry the necessary tools and instruments, a portable toolbox is an indispensable piece of equipment for maintenance workers.

[0003] To facilitate movement and free up hands, existing portable toolboxes are usually equipped with shoulder straps for maintenance personnel to carry. However, the length adjustment of toolbox shoulder straps on the market currently has significant shortcomings. Most of them use traditional D-ring buckles or similar clip structures for length adjustment, which is relatively cumbersome and usually requires the user to stop working and use both hands to loosen or tighten the strap.

[0004] For maintenance personnel who frequently switch between carrying and working positions, this slow adjustment method reduces work efficiency. Adjusting the strap length becomes particularly difficult when wearing gloves or supporting the equipment with one hand. An unsuitable strap length not only affects carrying comfort, but an excessively long strap is also prone to snagging in complex environments, posing a safety hazard to maintenance personnel.

[0005] Therefore, this utility model proposes a portable toolbox for communication maintenance to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a portable toolbox for communication maintenance, aiming to improve the problems of cumbersome and laborious adjustment of the shoulder strap length in some existing portable toolboxes for communication maintenance, which affects work efficiency.

[0007] This utility model provides a portable toolbox for communication maintenance, comprising: a box body and a shoulder strap connected to one end of the box body; and a storage mechanism fixed to the outer wall of the box body.

[0008] The storage mechanism includes a fixed rod, a fixed ring, a spring, a ratchet, a pawl, a rotating rod, and a spring-loaded assembly.

[0009] Furthermore, the fixing rod is horizontally fixed to the housing, the fixing ring is rotatably sleeved on the fixing rod, the other end of the shoulder strap is wound around the fixing ring, the spring is sleeved on the fixing rod, one end of which is connected to the fixing rod and the other end is connected to the fixing ring, the ratchet is coaxially fixed to one end of the fixing ring, the pawl is rotatably mounted on the housing and selectively engages or disengages with the teeth of the ratchet, the rotating rod is rotatably inserted through the housing and is connected to the pawl in a transmission connection, and the spring-loaded assembly is connected to the pawl.

[0010] Preferably, the portable toolbox for communication maintenance further includes a support mechanism located at the bottom of the box and used to support and lift the box.

[0011] Preferably, the pawl is used to drive the pawl to return to a state of engagement with the ratchet when the rotating rod is reset.

[0012] Preferably, the support mechanism includes a motor, a second rotating rod that is drivenly connected to the output end of the motor, and a support block that is rotatably engaged with the second rotating rod.

[0013] Preferably, the toolbox further includes a bottom shell, which is fixed to the bottom of the box body, and the support mechanism is housed within the bottom shell.

[0014] Preferably, the storage mechanism further includes a protective shell, which is detachably covered on the outside of the storage mechanism and fixed to the box body, with the operating end of the rotating rod extending out of the protective shell.

[0015] Preferably, the storage mechanism further includes an isolation ring, which is sleeved on the fixed rod and axially positioned between the spring and the fixed ring.

[0016] Preferably, the storage mechanism further includes a fixing plate, which is fixed to the box body, and the pawl and the spring-loaded assembly are both mounted on the fixing plate.

It achieves the technical effect of quickly and conveniently adjusting the strap length, improving the efficiency of maintenance personnel in carrying and retrieving toolboxes.

[0020] 2. This utility model solves the problems of existing toolboxes being difficult to place in harsh outdoor environments such as mud and water accumulation, being easily damaged, and being unstable by setting a support mechanism driven by a motor and capable of extending support blocks at the bottom of the box. It achieves the technical effect of enabling the box to be stably supported and lifted off the ground, effectively protecting the cleanliness of the box and the safety of the tools, and enhancing the environmental adaptability of the toolbox.

[0021] 3. This utility model solves the problem that traditional toolboxes have limited functionality and cannot simultaneously meet the needs of convenient carrying and adaptability to complex environments by integrating the carrying strap storage mechanism and the electric support mechanism onto the box body. It achieves a compact structure, high functional integration, and significantly improves the convenience and reliability of communication maintenance personnel in various working scenarios.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Reference Figures 1 to 5 This utility model provides a portable toolbox for communication maintenance, which aims to solve the problems of cumbersome adjustment of the shoulder strap length and inconvenience of placing the toolbox in complex outdoor ground environments, making it susceptible to dirt.

[0032] like Figure 1 and Figure 2 As shown, it includes a case 1 and a storage mechanism 4 fixed to the outer wall of the case 1. The case 1 is used to hold maintenance tools, and the storage mechanism 4 is used to store and fix the length of the shoulder strap 6. One end of the shoulder strap 6 is connected to the case 1.

[0033] Specifically, the storage mechanism 4 includes a fixing rod 41, which is laterally fixed to the housing 1. The storage mechanism 4 also includes a fixing ring 43 rotatably fitted onto the fixing rod 41, with the other end of the shoulder strap 6 wound around the fixing ring 43. The storage mechanism 4 further includes a spring coil 44 fitted onto the fixing rod 41, with one end of the spring coil 44 connected to the fixing rod 41 and the other end connected to the fixing ring 43, providing winding power to the fixing ring 43. The storage mechanism 4 also includes a component coaxially fixed to one end of the fixing ring 43. The storage mechanism 4 also includes a ratchet 45, which is rotatably mounted on the housing 1 and selectively engages or disengages from the teeth of the ratchet 45. The storage mechanism 4 also includes a rotating rod 48 rotatably passing through the housing 1 and drivingly connected to the ratchet 47, for driving the ratchet 47 to rotate to disengage from the ratchet 45. The storage mechanism 4 further includes a spring-loaded assembly 49 connected to the ratchet 47, for driving the ratchet 47 to return to the state of engagement with the ratchet 45 when the rotating rod 48 returns to its original position.

[0034] Reference Figure 1 The portable toolbox for communication maintenance also includes a support mechanism 5, and the support mechanism 5 and the aforementioned box 1 form a specific structural fit and connection relationship.

[0035] Reference Figure 1 and Figure 5 The toolbox also includes a bottom shell 2, which is fixed to the bottom of the box body 1. The support mechanism 5 is housed in the bottom shell 2. The support mechanism 5 includes a motor 52, a rotating rod 51, and a support block 53. The output end of the motor 52 is connected to the rotating rod 51. The support block 53 is rotatably engaged with the rotating rod 51. When the motor 52 drives the rotating rod 51 to rotate, the support block 53, which is threadedly engaged with the rotating rod 51, will extend or retract linearly along the axial direction of the rotating rod 51, thereby supporting and lifting the box body 1 from the ground.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The storage mechanism 4 also includes a protective shell 3, which is detachably covered on the outside of the storage mechanism 4 and fixed to the housing 1. The operating end of the rotating rod 48 extends out of the protective shell 3. The storage mechanism 4 also includes an isolation ring 42, which is sleeved on the fixed rod 41 and axially positioned between the spring 44 and the fixed ring 43. The storage mechanism 4 also includes a fixed plate 46, which is fixed to the housing 1. The pawl 47 and the spring-loaded assembly 49 are both mounted on the fixed plate 46. The spring-loaded assembly 49 includes a moving block 491, a connecting rod 492, a force plate 493, a damping rod 494, and a spring bar 495. The moving block 491 can slide on the fixed plate 46. One end of the connecting rod 492 is connected to the pawl 47 and the other end is connected to the moving block 491. The spring bar 495 is used to apply an elastic restoring force to the moving block 491. The spring bar 495 acts on the moving block 491 through the force plate 493 and the damping rod 494.

[0037] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the length of the shoulder strap 6, the operator rotates the rotating rod 48. The rotating rod 48 drives the pawl 47 to rotate around its rotation axis through the transmission connection, thereby disengaging the pawl 47 from the ratchet 45. At this time, the rotation of the ratchet 45 and the fixed ring 43 is no longer restricted. The elastic potential energy stored in the spring spring 44 is released, driving the fixed ring 43 to rotate and automatically wind and store the shoulder strap 6. When the shoulder strap 6 is stored to the appropriate length, the operator releases the rotating rod 48. The spring return component 49 drives the pawl 47 to rotate in the opposite direction to reset, so that the pawl 47 engages with the teeth of the ratchet 45 again, thereby locking the fixed ring 43, and the length of the shoulder strap 6 is fixed.

[0038] When maintenance work needs to be carried out on muddy or uneven ground, the operator starts the motor 52 installed in the bottom shell 2. The output end of the motor 52 drives the rotating rod 51 to rotate. The rotation of the rotating rod 51 drives the linear movement of the support block 53. The support block 53 extends along the axial direction of the rotating rod 51 until it contacts the ground and supports and lifts the box 1, making it off the ground. Reversing the motor 52 will cause the support block 53 to rotate back into the bottom shell 2.
