[0044] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] With the continuous development and progress of society, electricity has become an indispensable part of people's daily life. When a transmission line fails, workers usually need to carry a maintenance tool box to repair the faulty line.

[0046] CN210414488U discloses a standardized tool box for power distribution network emergency repairs. The box includes a shoulder strap and a drawer. The drawer slides relative to the box and has a tool storage slot inside. Maintenance personnel can carry the tool box on their back using the shoulder strap. Tools can be retrieved from the box by pulling out the drawer.

[0047] However, when performing aerial work, if the tool box is carried up a pole or tower during maintenance, the shoulder strap may easily slip during the climbing process, which may cause the risk of falling objects, thereby threatening the safety of the maintenance personnel and surrounding personnel.

[0048] Therefore, using the above-mentioned tool box, workers need to pre-collect the necessary tools on a flat surface, then carry them to the maintenance location for repair. If other tools are needed for repair, they need to go back and forth between the box and the maintenance location to retrieve the items, making the maintenance work cumbersome and inefficient. Although repair efficiency can be improved by adding a staff member to assist in retrieving tools, this will also increase labor costs.

[0049] In view of this, the present application provides a tool box for power maintenance, including a box body, a waist belt, a positioning mechanism and a drive assembly. The waist belt includes two belt bodies, the first ends of the two belt bodies are connected to the box body, and the second ends of the two belt bodies extend out of the box body and can be buckled with each other. In addition, at least one belt body is an adjustable belt body with adjustable length. The positioning mechanism is arranged in the box body and is connected to the adjustable belt body. The positioning mechanism can be used to lock the adjustable belt body. The drive assembly is arranged in the box body, and the drive assembly includes a drive motor and a transmission member. The drive motor can drive the transmission member to rotate, and the transmission member can drive the positioning mechanism to move.

[0050] With this arrangement, maintenance personnel can secure the toolbox around their waist using the waist belt and adjust the adjustable belt to accommodate varying belt length requirements. Driven by the drive assembly, the positioning mechanism, driven by the transmission element, moves, connecting with the adjustable belt and locking it. This allows maintenance personnel to carry the power maintenance toolbox with them when climbing a pole or tower. The positioning mechanism secures the toolbox to the waist of the maintenance personnel, preventing it from falling and hindering their operations while climbing the pole (tower) or once they reach the maintenance location. This improves both efficiency and safety during power maintenance.

[0051] The contents of this application will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the contents of this application more clearly and in detail.

[0052] Figure 1 This is a front view of the power maintenance toolbox provided in an embodiment of the present application. Figure 2 A schematic diagram of the internal structure of the power maintenance toolbox provided in an embodiment of the present application at an angle.

[0053] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a power maintenance tool box 10. The power maintenance tool box 10 includes a box body 100 and a waist belt 200.

[0054] The waist belt 200 includes two straps 210. The first ends of the two straps 210 are connected to the inside of the box 100, and the second ends of the two straps 210 extend outside the box 100. The second ends of the two straps 210 can be interlocked. This allows the box 100 to be tied around the waist of the maintenance worker via the waist belt 200, making the power maintenance tool box 10 easy to carry without occupying hands and affecting maintenance work.

[0055] At least one of the two straps 210 is an adjustable strap 210a with adjustable length. For example, one strap 210 may be adjustable, while the other strap 210 is not adjustable. Adjusting the length of the adjustable strap 210a adjusts the overall length of the waist belt 200. Alternatively, both straps 210 may be adjustable, and adjusting the length of either or both of them simultaneously adjusts the overall length of the waist belt 200. By adjusting the length of the adjustable strap 210a, different waist belt 200 length requirements can be met, accommodating maintenance personnel of varying body shapes.

[0056] It should be noted that the length of the adjustable belt 210a can be adjusted in a variety of ways. For example, the adjustable belt 210a can be wound around a reel within the housing 100, and the reel can be rotated to release or retract the adjustable belt. Alternatively, a ratchet and a rack can be used to adjust the length of the belt by rotating the ratchet. The specific methods are not limited herein.

[0057] The power maintenance toolbox 10 also includes a positioning mechanism 300 and a drive assembly 400 disposed within the housing 100. The positioning mechanism 300 is connected to the adjustable strap 210a and is used to lock the adjustable strap 210a. When the maintenance worker adjusts the adjustable strap 210a to a desired length and engages the second ends of the two straps 210, the positioning mechanism 300 locks the adjustable strap 210a, fixing the length of the adjustable strap 210a. This allows the waist belt 200 to securely fasten the housing 100 to the maintenance worker's waist, preventing the worker from slipping or falling during the climb, which could pose a safety risk.

[0058] The drive assembly 400 may include a drive motor 410 and a transmission member 420. The drive motor 410 can drive the transmission member 420 to rotate, which in turn can drive the positioning mechanism 300 to move. Consequently, driven by the drive motor 410, the positioning mechanism 300 can contact or separate from the adjustable belt 210a, and can lock or unlock the adjustable belt 210a. Thus, the coordination of the drive motor 410 and the transmission member 420 enables precise control of the movement of the positioning mechanism 300.

[0060] Figure 3 The internal structure of the power maintenance tool box provided in the embodiment of the present application at another angle. As an embodiment, refer to Figure 3As shown, the side wall of the box body 100 may be provided with two through holes 140 so that the interior of the box body 100 can be connected to the outside. The second ends of the two straps 210 may extend out of the box body 100 through the corresponding through holes 140 and be interlocked.

[0061] Furthermore, a roller 313 may be installed in the housing 100 and rotatably connected to the housing 100. The first end of the adjustable belt 210a may be connected to and wound around the roller 313, thereby enabling the adjustable belt 210a to be retracted and extended by the rotation of the roller 313. When a maintenance worker grips the second end of the adjustable belt 210a and applies force outward, the roller 313 may rotate relative to the housing 100, driving the adjustable belt 210a wound around the roller 313 to extend outward.

[0062] It is understood that when only one adjustable belt 210a is provided, only one roller 313 may be installed in the box 100 to drive the adjustable belt 210a to be retracted and extended. When both belts 210 are adjustable belts 210a, two rollers 313 may be installed in the box 100 to respectively drive the corresponding adjustable belt 210a wound around the rollers 313 to be retracted and extended.

[0063] For example, when both belts 210 are adjustable belts 210a, the two through holes 140 and the two rollers 313 can be symmetrically arranged with the center line of the box body 100 in the length direction or width direction as the axis, thereby improving the stability and strength of the toolbox structure and simplifying the processing and assembly of the toolbox.

[0064] Continue to refer to Figure 1 and Figure 2 As shown, the power maintenance tool box 10 may further include a box cover 600, which may cover the opening at the top of the box body 100 and seal the box body 100 to prevent dust or liquid from entering the box body 100. The box body 100 and the box cover 600 are detachably connected so that maintenance personnel can take out the maintenance tools in the box body 100 at any time during operation.

[0065] For example, the side of the box cover 600 away from the waist belt 200 can be rotatably connected to the box body 100 to form a connection end. Therefore, during the rotation process, a movable end is formed on the other side of the box cover 600. This movable end can move relative to the box body 100 and can be attached to or separated from the surface of the box body 100, thereby exposing the opening in the box body 100 and making it easier for maintenance personnel to take tools.

[0066] To prevent the box lid 600 from being opened by mistake and to make the opening of the box lid 600 more convenient, a first magnetic member 130 can be embedded in the end near the movable end of the box lid 600. Correspondingly, a second magnetic member 610 can also be embedded in the top of the box body 100 near the side of the waist belt 200. In addition, the first magnetic member 130 can be magnetically attracted to the second magnetic member 610. Under normal circumstances, under the action of magnetic force, the box lid 600 is sealed on the box body 100. When it is necessary to replace or remove maintenance tools, maintenance personnel can manually apply force to overcome the attraction between the first magnetic member 130 and the second magnetic member 610 and flip open the box lid 600.

[0067] To facilitate maintenance personnel to take the tools inside the box 100, refer to Figure 2 As shown, the power maintenance tool box 10 may further include a partition 110 and a lifting mechanism 500. Partition 110 is movably connected within the box 100 and can be used to store maintenance tools, isolating them from other structures and reducing the chance of collisions between them. Lifting mechanism 500 is connected between partition 110 and drive assembly 400. Drive assembly 400 drives lifting mechanism 500, thereby causing partition 110 to rise and fall along the height of box 100.

[0068] In this way, when it is necessary to replace or remove tools, the partition 110 can be raised along the height direction of the box body 100 by driving the driving assembly 400 under the drive of the lifting mechanism 500. At this time, the distance between the partition 110 and the maintenance tools on the partition 110 and the top of the box body 100 is shortened, so that when the box cover 600 is opened, the depth to which the maintenance personnel need to extend their hands into the box body 100 is also reduced, thereby facilitating the maintenance personnel to quickly identify and remove tools. At the same time, the driving assembly 400 can also synchronously drive the positioning mechanism 300 to move, and the positioning mechanism 300 can lock the adjustable belt body 210a under the drive of the driving assembly 400, thereby achieving the length control of the adjustable belt body 210a and synchronously locking the box body 100 to the waist of the maintenance personnel.

[0069] The drive assembly 400 provided in the embodiment of the present application is described in detail below.

[0070] Reference Figure 2 and Figure 3 As shown, as one embodiment, the transmission member 420 may include a cam 422. When the cam 422 is driven by the drive motor 410, the cam 422 simultaneously pushes the positioning mechanism 300 and the lifting mechanism 500. This simplifies the transmission design structure, facilitating easy manufacturing and maintenance, and providing high reliability and a long service life. Furthermore, the use of the cam 422 makes the transmission structure more compact, saving internal space.

[0071] Specifically, the transmission member 420 further includes a rotating shaft 421, through which the cam 422 can be connected to the output end of the drive motor 410. The rotating shaft 421 is coaxially arranged with the output shaft of the drive motor 410. The cam 422 can rotate under the drive of the drive motor 410 and drive the positioning mechanism 300 and the lifting mechanism 500.

[0072] For example, the cam 422 can be a bidirectional cam. The bidirectional cam can be a symmetrical structure, which is convenient to manufacture and has better stability. The two ends of the bidirectional cam can be arc surfaces, and the middle can be extended by a plane or a curved surface to form a closed structure. For example, the outline of the bidirectional cam can be set to an elliptical disk. Figure 3 As shown, the positioning mechanism 300 and the lifting mechanism 500 can be respectively placed at opposite ends of the bidirectional cam, so that when the bidirectional cam rotates, the bidirectional cam can simultaneously drive the positioning mechanism 300 and the lifting mechanism 500 to move in opposite directions.

[0073] Figure 4 This is a connection diagram of the transmission member provided in the embodiment of the present application in the initial position. It should be noted that in order to make the relative positions of the transmission member 420, the positioning mechanism 300 and the lifting mechanism 500 clear, Figure 4 The waist belt 200 is not shown.

[0074] Reference Figure 4 As shown, taking the bidirectional cam as an elliptical disc as an example, in the initial position, the two opposite ends corresponding to the minor axis of the elliptical disc respectively contact the positioning mechanism 300 and the lifting mechanism 500. The two opposite ends corresponding to the major axis of the elliptical disc do not contact either the positioning mechanism 300 or the lifting mechanism 500.

[0075] When the driving motor 410 is working, the elliptical disk can rotate 90 degrees relative to the rotating shaft 421 and reach the working position. At this time, the two opposite ends corresponding to the minor axis of the elliptical disk are separated from the positioning mechanism 300 and the lifting mechanism 500, and the two opposite ends corresponding to the major axis of the elliptical disk are offset from the positioning mechanism 300 and the lifting mechanism 500 (such as Figure 3 As the elliptical disk rotates, the positioning mechanism 300 and the lifting mechanism 500 are pushed by the disk, moving in opposite directions. The distances between the positioning mechanism 300, the lifting mechanism 500, and the rotating shaft 421 gradually increase until the elliptical disk reaches its operating position, at which point the distances between the positioning mechanism 300, the lifting mechanism 500, and the rotating shaft 421 reach their maximum. It will be appreciated that when the transmission member 420 is in the operating position, the positioning mechanism 300 locks the adjustable belt 210a to maintain its length. The lifting mechanism 500, meanwhile, raises the partition 110 to its highest position, making it easier for maintenance personnel to access tools.

[0076] Continue to refer to Figure 2-Figure 4As shown, the lifting mechanism 500 may include a first wedge block 510 and a second wedge block 520. The first wedge block 510 is slidably connected to the box body 100. The second wedge block 520 is connected to the partition 110, and the second wedge block 520 can slide with the first wedge block 510 through a wedge surface.

[0077] It is understood that when the transmission member 420 changes from the initial position to the working position, the first wedge block 510 slides in the direction away from the positioning mechanism 300, thereby driving the second wedge block 520 to rise upward, thereby driving the partition 110 to rise along the height direction of the box body 100. It should be noted that the sliding of the first wedge block 510 on the box body 100 can be achieved in a variety of ways. For example, it can be as follows Figure 3 As shown, a chute 150 is provided at the bottom of the box body 100 so that the first wedge block 510 slides in the chute 150. Alternatively, a groove may be provided at the bottom of the first wedge block 510, and a raised track slidably connected thereto may be provided at the bottom of the box body 100, which is not limited here.

[0078] With this arrangement, the driving force can be efficiently transmitted and amplified through the cooperation of the wedge surfaces in the first wedge block 510 and the second wedge block 520 , and the lifting mechanism 500 can be designed to be more compact, thereby reducing the space occupied by the interior of the box body 100 .

[0079] The lifting mechanism 500 may further include a first restoring member 530, which is connected between the box body 100 and the first wedge block 510. The first restoring member 530 may be used to drive the first wedge block 510 to return to its initial position.

[0080] The first reset member 530 may be a spring, or a hydraulic rod, a pneumatic rod, a compressible elastic tube, etc. As long as it can drive the first wedge block 510 to return to the initial position, it is not limited here.

[0081] The following description uses the example of a spring as the first return member 530. When the drive motor 410 drives the transmission member 420 from its initial position to its operating position, the first wedge block 510 moves from its initial position to its operating position, driving the partition 110 upward. During this process, the spring connected between the housing 100 and the first wedge block 510 may be compressed or stretched, accumulating elastic potential energy.

[0082] When the driving motor 410 drives the transmission member 420 to change from the working position to the initial position, the first wedge block 510 in the working position is no longer in contact with the transmission member 420, and the driving force originally abutting against the first wedge block 510 disappears. At this time, the elastic potential energy accumulated in the spring is released, which can drive the first wedge block 510 to move toward the initial position to achieve return.

[0083] Exemplarily, the second wedge block 520 may be connected to the bottom of the partition 110 , and a lifting groove 191 is defined in the box body 100 , along which the partition 110 may slide.

[0084] In some embodiments, a third restoring member 190 may be connected to the top of the partition 110. One end of the third restoring member 190 may be connected to the top wall of the lifting groove 191, and the other end may be connected to the top surface of the partition 110. Furthermore, the third restoring member 190 may drive the partition 110 to return to its initial state. Thus, the provision of the third restoring member 190 may enable the partition 110 to return to its initial state more quickly.

[0085] The third reset member 190 can be a spring, or a hydraulic rod, a pneumatic rod, a compressible elastic tube, etc. As long as it can drive the first wedge block 510 to return to the initial position, it is not limited here.

[0086] In other embodiments, the partition 110 can also slide along the lifting groove 191 under the action of its own weight and eventually slide to the bottom of the lifting groove 191, abutting against the bottom wall of the lifting groove 191 and returning to its original state. In this way, the internal structure of the box body 100 can be simplified and the difficulty of assembling the box body 100 can be reduced.

[0087] The specific structure of the positioning mechanism 300 provided in the embodiment of the present application is described below.

[0088] Continue to refer to Figure 3 As shown, the positioning mechanism 300 may include an adjustment assembly 310, a locking assembly 320, and a second reset member 330. The adjustment assembly 310 may be connected to the drive assembly 400. Specifically, the adjustment assembly 310 may be connected to the transmission member 420, and the adjustment assembly 310 may be used to drive the adjustable belt body 210a to extend and retract. It is understood that the adjustment assembly 310 may be indirectly connected to the transmission member 420 or directly connected to the transmission member 420, as long as it can move under the drive of the drive assembly 400, and this is not limited herein.

[0089] The locking assembly 320 can be linked to the adjusting assembly 310. When the transmission member 420 drives the adjusting assembly 310 to move, the locking assembly 320 can move along with the adjusting assembly 310. In addition, the locking assembly 320 can press the adjustable belt 210a against the box body 100 so that the length of the adjustable belt 210a is no longer variable. It should be noted that the locking assembly 320 and the adjusting assembly 310 can be linked, and the locking assembly 320 and the adjusting assembly 310 can also be linked by connecting the locking assembly 320 to the adjusting assembly 310 to achieve the linkage, or by other structures, which are not limited here.

[0090] The second restoring member 330 may be connected to the adjusting assembly 310 , or the second restoring member 330 may also be connected to the locking assembly 320 , so that when the second restoring member 330 drives one of the connected members to move, the other member may also move accordingly.

[0091] It is understood that, similar to the first return member 530, the second return member 330 can be a spring, or alternatively, a hydraulic rod, a pneumatic rod, a compressible elastic tube, or other structure. As long as it can drive the positioning mechanism 300 to its initial position, no limitation is imposed herein. The following description uses the spring as an example of the second return member 330.

[0092] When the drive motor 410 drives the transmission member 420 from its initial position to its working position, the transmission member 420 drives the adjustment assembly 310 and the locking assembly 320 to move away from the transmission member 420. During this process, the locking assembly 320 can press the adjustable belt 210a against the housing 100 so that the length of the adjustable belt 210a extending outside the housing 100 does not change. At the same time, the adjustment assembly 310 can cause the adjustable belt 210a to expand and contract. In this way, when the locking assembly 320 continues to apply pressure to the adjustable belt 210a, the length of the adjustable belt 210a inside the housing 100 can be adaptively changed, thereby preventing the adjustable belt 210a from breaking due to concentrated force, which would affect the normal use of the power maintenance tool box 10.

[0093] It is understood that the locking assembly 320 can be to press the adjustable belt 210a against the side wall of the box 100, or to open a positioning groove 120 on the side wall of the box 100 (such as Figure 3 As shown), the locking assembly 320 can press the adjustable belt body 210a into the positioning groove 120, which is not limited here.

[0094] Furthermore, during this process, the spring connected between the box body 100 and the locking assembly 320 or between the box body 100 and the adjusting assembly 310 may be compressed or stretched to accumulate elastic potential energy.

[0095] When the driving motor 410 drives the transmission member 420 to change from the working position to the initial position, the driving force that originally drives the adjustment component 310 and the locking component 320 to move disappears. At this time, the elastic potential energy accumulated in the spring is released, thereby driving the adjustment component 310 and the locking component 320 to return to the initial position, thereby releasing the lock on the adjustable belt body 210a.

[0096] The specific structure of the adjustment component 310 is described below.

[0097] Reference Figure 3As shown, the adjustment assembly 310 may include a first rack 311 and a first gear 312. The first rack 311 is in transmission connection with the drive assembly 400, and the drive assembly 400 can drive the first rack 311 to move. Specifically, the first rack 311 can be in transmission connection with the transmission member 420 and move under the drive of the transmission member 420. The first gear 312 is engaged with the first rack 311 and can be coaxially arranged with a roller 313 used to wind the adjustable belt 210a. Thus, the first gear 312 can rotate under the drive of the first rack 311, thereby driving the roller 313 coaxially arranged therewith to rotate, thereby achieving contraction of the adjustable belt 210a.

[0098] As an embodiment, when both belts 210 are adjustable belts 210a, the adjustment assembly 310 may further include a linkage 314 to improve drive efficiency. In this case, two first racks 311, two first gears 312, and two locking assemblies 320 may be provided within the housing 100. Furthermore, the two first racks 311 may be respectively connected to the two adjustable belts 210a. Both first racks 311 may be connected to the linkage 314, and the drive assembly 400 may drive the linkage 314 to move.

[0099] Thus, when the driving assembly 400 drives the linkage member 314 to move, the two first racks 311 can move synchronously under the drive of the linkage member 314 and drive the two first gears 312 to rotate. At the same time, since the adjustment assembly 310 is linked with the locking assembly 320, the two locking assemblies 320 can also be driven to move synchronously and press the adjustable belt body 210a, thereby improving the overall driving efficiency and working efficiency.

[0100] Furthermore, the linkage member 314 can also be connected to the two locking components 320, thereby realizing the linkage of the adjustment component 310 and the locking component 320, and the synchronous driving of the two adjustment components 310 and the two locking components 320 can be achieved only through the linkage member 314, with a simple structure and high driving efficiency.

[0101] The specific structure of the locking assembly 320 is described below.

[0102] Continue to refer to Figure 3 As shown, the locking assembly 320 may include a movable member 321 and a pressing member 322. The movable member 321 may be linked to the adjustment assembly 310. The pressing member 322 is connected to one end of the movable member 321 that faces the adjustable belt 210a, and the pressing member 322 is used to compress the adjustable belt 210a. Thus, the movable member 321 may be driven by the adjustment assembly 310 to move toward the side wall of the housing 100 away from the drive assembly 400, and the pressing member 322 may then press the adjustable belt 210a against the side wall of the housing 100.

[0103] For example, the movable member 321 can be slidably connected to the bottom wall of the box body 100, thereby improving the stability of the movement of the movable member 321. For example, a movable groove 160 (such as Figure 3 As shown, the movable member 321 can slide within the movable groove 160. Alternatively, a guide protrusion can be provided on the bottom of the housing 100, and a groove can be provided on the bottom of the movable member 321, through which the movable member 321 is slidably connected to the guide protrusion. Taking the movable groove 160 provided on the bottom of the housing 100 as an example, when the second reset member 330 is connected to the locking assembly 320, the second reset member 330 can be connected between the movable member 321 and the groove wall of the movable groove 160, thereby resetting the movable member 321 and the connected pressing member 322.

[0104] To further prevent the adjustable belt 210a from sliding and causing the tool box to become loose, as an embodiment, a positioning groove 120 may be formed on the side wall of the box body 100, and the pressing member 322 may press the adjustable belt 210a into the positioning groove 120. In this way, by increasing the contact surface between the adjustable belt 210a and the inner wall of the box body 100, the friction between the adjustable belt 210a and the box body 100 can be increased, further reducing the risk of the adjustable belt 210a sliding.

[0105] Figure 5 for Figure 3 Enlarged view of point B in the middle. Figure 5 As shown in FIG. 1 , as an embodiment, the width of the pressing member 322 gradually decreases from one end where the pressing member 322 is connected to the movable member 321 to the other end of the pressing member 322. For example, the pressing member 322 may be in the shape of a truncated cone.

[0106] In this way, when the pressing piece 322 contacts the adjustable belt body 210a and presses it against the positioning groove 120, the adjustable belt body 210a will fit the surface of the pressing piece 322. Compared with using a pressing piece 322 of the same width (such as a rectangular block), the above-mentioned setting can make the transition of the adjustable belt body 210a at the bending part more uniform and soft, thereby avoiding the occurrence of breakage of the adjustable belt body 210a due to stress concentration, and improving the reliability of the power maintenance tool box 10.

[0107] In some embodiments, the groove walls on opposite sides of the positioning groove 120 may be covered with an elastic layer 121 , and the elastic layer 121 is in close contact with the adjustable belt body 210 a outside the pressing member 322 .

[0108] It is understood that as the pressing member 322 gradually moves toward the bottom of the positioning groove 120, the adjustable belt body 210a will be pressed against the elastic layers 121 on both sides by the pressing member 322 until it is pressed against the bottom of the positioning groove 120. At this time, the elastic layers 121 on both sides will deform and provide a reaction force for the adjustable belt body 210a, thereby improving the stability of the pressing member 322 in pressing the adjustable belt body 210a.

[0109] Illustratively, the thickness of the elastic layer 121 may gradually increase from the notch of the positioning groove 120 toward the bottom of the groove to match the outer contour of the pressing member 322 , thereby achieving compression of the adjustable belt body 210 a and the pressing member 322 without causing motion interference.

[0110] Combine Figure 3 and Figure 5 As shown, the positioning mechanism 300 may further include a limiting assembly 340. The limiting assembly 340 may be linked to the adjusting assembly 310 and may be used to limit the position of the locking assembly 320 when the locking assembly 320 compresses the adjustable strap 210a. Thus, once the locking assembly 320 compresses the adjustable strap 210a, the limiting assembly 340 limits the position of the locking assembly 320, preventing the locking assembly 320 from shifting due to vibration or other external factors, which could cause the waist belt 200 to become loose. Furthermore, because the limiting assembly 340 is also linked to the adjusting assembly 310, when the adjusting assembly 310 is driven, the limiting assembly 340 can move synchronously with the locking assembly 320, thereby improving driving efficiency and work efficiency.

[0111] Exemplarily, the limiting assembly 340 may include a second rack 341, a second gear 342, and a third rack 343. The second rack 341 may be linked to the adjustment assembly 310. For example, the second rack 341 may be connected to the linkage 314, or the second rack 341 may be connected to other structures in the adjustment assembly 310, as long as the second rack 341 can follow the movement of the adjustment assembly 310.

[0112] The second gear 342 can be engaged with the second rack 341 and can rotate driven by the second rack 341. The third rack 343 can be in transmission connection with the second gear 342 and can be used to define the position of the locking assembly 320.

[0113] In this way, the third rack 343 can be driven by the transmission of the gear rack, thereby limiting the position of the locking assembly 320. In addition, the control accuracy and stability of the gear rack are high.

[0114] In some embodiments, to achieve a transmission connection between the third rack 343 and the second gear 342, the limiting assembly 340 may further include a third gear (not shown) coaxially disposed with the second gear 342. Specifically, the second gear 342 and the third gear may be rotatably connected to the same rotating axis. In this case, the third gear may mesh with the third rack 343, allowing the third rack 343 to approach the positioning member under the drive of the third gear and limit its movement. This allows designs with different numbers of teeth and pitches to accommodate varying travel distances.

[0115] In other embodiments, the second gear 342 can mesh with both the second rack 341 and the third rack 343. The second rack 341 and the third rack 343 can be spatially staggered to avoid interference. Thus, the rotation of the second gear 342 alone can drive the third rack 343 toward the positioning member and restrict its movement. This simplifies the transmission structure and reduces the space occupied by the housing 100, making the power maintenance tool box 10 even lighter.

[0116] Exemplarily, teeth are provided along a portion of the length direction of the third rack 343 , and the teeth are provided on a side away from the pressing member 322 , and the teeth can be transmission-connected to the second gear 342 .

[0117] In some embodiments, an end of the third rack 343 away from the second gear 342 may be provided with an inclined surface 3431, which may abut against the outer contour of the locking assembly 320. In this way, the inclined surface 3431 can increase the contact area between the third rack 343 and the locking assembly 320, thereby enhancing its limiting effect.

[0118] Correspondingly, the locking assembly 320 may further include an arcuate surface 323 (see Figure 5 As shown in FIG, the arcuate surface 323 is connected between the clamping member and the movable member 321 and can cooperate with the inclined surface 3431 on the third rack 343, thereby further increasing the contact area between the third rack 343 and the locking assembly 320. When the clamping member presses the adjustable belt body 210a into the positioning groove 120, the inclined surface 3431 on the third rack 343 can abut against the arcuate surface 323 to restrict its movement.

[0119] In other embodiments, the end of the third rack 343 away from the second gear 342 can be set as a plane, and the locking assembly 320 can further include a connecting member 324 (see Figure 6As shown in FIG, a connecting member 324 is disposed between the clamping member and the movable member 321. A limiting slot is defined in the connecting member 324. The limiting slot can have a width equal to that of the third rack 343, and the limiting slot allows the end of the third rack 343 to be inserted therein. Thus, when the clamping member presses the adjustable belt 210a against the positioning slot 120, the third rack 343 can extend into the positioning slot 120 and restrict the movement of the locking assembly 320.

[0120] Alternatively, a groove may be provided at the end of the third rack 343 and a protrusion may be provided at a corresponding position of the connecting member 324 , as long as the engagement between the third rack 343 and the connecting member 324 can be achieved.

[0121] It can be understood that when the locking assembly 320 presses the adjustable belt body 210a into the positioning groove 120, a accommodating chamber 180 is also provided on the box body 100, and the accommodating chamber 180 can be used to accommodate the second gear 342 and the third rack 343, and the accommodating chamber 180 can be connected to the positioning groove 120, so that the third rack 343 can limit the locking assembly 320.

[0122] Combine Figure 3 and Figure 5 As shown, when both straps 210 are adjustable straps 210a, the limiting assembly 340 may further include a guide member 344. A guide slot 170 is correspondingly defined on the sidewall of the housing 100, and the guide member 344 is movable relative to the guide slot 170. In this case, the housing 100 may be provided with two first racks 311, two first gears 312, two second gears 342, two second racks 341, two third racks 343, and two sets of locking assemblies 320.

[0123] The two second racks 341 corresponding to the two adjustable belts 210a can be located on both sides of the guide member 344. Therefore, when the guide member 344 is driven, the second racks 341 on both sides of the guide member 344 can simultaneously drive the two second gears 342 to rotate, thereby driving the third rack 343 to move, thereby limiting the position of the locking assembly 320 and improving the working efficiency of the power maintenance tool box 10.

[0124] It is understandable that the second rack 341 can be formed integrally on the guide member 344 or can be separately connected to the guide member 344, which is not limited here.

[0125] Figure 6 A schematic diagram of the structure of the common components provided in the embodiment of the present application.

[0126] Reference Figure 6As shown, as an embodiment, the second rack 341 and the first rack 311 can be respectively located on the two side surfaces of the common member 350. Thus, by integrating the first rack 311 and the second rack 341 into one body, the common member 350 can both drive the first gear 312 to rotate to achieve the extension and retraction of the adjustable belt 210a, and drive the second gear 342 to rotate to drive the third rack 343 to move, thereby reducing the number of internal parts of the power maintenance tool box 10 and achieving a smaller and lighter power maintenance tool box 10.
