It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0043] like Figures 1 to 9 As shown, the present application provides an operation and maintenance protection tool box, and an embodiment of the operation and maintenance protection tool box includes: a box body 10, an inner box 20, a protection component 30, a buffer component 40 and a damping mechanism 50. The box body 10 includes an outer box and a box cover that can be opened and closed on the outer box. The inner box 20 is arranged in the outer box, and each corner of the inner box 20 is provided with a movable groove 21 and a support spring 22 arranged in each movable groove 21. The protection component 30 includes a protection plate 31 that can be opened and closed on the inner box 20. The buffer assembly 40 includes a buffer sleeve 41, a limit seat 42, a telescopic rod 43, a magnet rod 44, and a magnet plate 45. The limit seat 42 abuts against each support spring 22 and is located in the movable groove 21. The buffer sleeve 41 is arranged on the limit seat 42 and is located in the movable groove 21. The magnet plate 45 is movably arranged in the buffer sleeve 41. The magnet rod 44 is connected to the magnet plate 45 in the buffer sleeve 41. The magnet rod 44 is located on the side of the magnet plate 45 away from the limit seat 42. The first end of the telescopic rod 43 is connected to the magnet rod 44, and the second end of the telescopic rod 43 is connected to each corner of the protective plate 31. The damping mechanism 50 abuts between the magnet rod 44 and the buffer sleeve 41.

[0044] By applying the technical solution of this embodiment, when in use, the box cover is opened to facilitate opening the box body 10, and the tools can be stored separately in the inner box 20. When the box body 10 is opened, based on the elastic force of the support spring 22, the buffer assembly 40 and the protection assembly 30 are pushed upward to separate the protection assembly 30 from the inner box 20, thereby realizing the automatic opening of the inner box 20, which is convenient for the staff to take the measurement and maintenance tools. Due to the uncontrollable factors in the external environment, when an object falls toward the box 10 unexpectedly, the setting of the protective component 30 allows the external collision object to contact the protective plate 31 first, and the protective plate 31 can be used for buffering and protection, and the impact force borne by the protective plate 31 can be initially relieved and offset, so as to achieve the purpose of reducing the impact force; and when the impact force is too large, based on the impact force on the protective plate 31, the protective plate 31 pushes the telescopic rod 43 downward toward the inside of the buffer sleeve 41, and synchronously drives the magnet rod 44 downward under the thrust of the telescopic rod 43. During the downward movement of the magnet rod 44, it will contact the damping mechanism 50, and the damping mechanism 50 is used to damp and relieve the pressure of the magnet rod 44, and then the downward pressure of the protective plate 31 is buffered and offset, so as to achieve the purpose of effectively protecting the tools and reduce the possibility of damage to the tools inside the toolbox. Therefore, the technical solution of this embodiment effectively solves the problem of easy damage to the tools inside the toolbox in the related technology.

[0045] like Figures 8 to 11 As shown, a plurality of buffer grooves 441 are provided on the inner wall of the magnet rod 44, and the plurality of buffer grooves 441 are arranged at intervals along the axis of the magnet rod 44. A mounting groove connected to any buffer groove 441 is provided on the inner wall of the buffer sleeve 41, and the damping mechanism 50 is rotatably located in the mounting groove and can abut against the buffer groove 441 corresponding to the mounting groove. This design absorbs the impact energy through the compression of the telescopic rod 43 and the movement of the magnet rod 44 when the protective assembly 30 is subjected to external impact, and at the same time, the damping mechanism 50 can further reduce vibration and impact, and protect the tools in the inner box 20 from damage.

[0046] like Figures 8 to 11 As shown, the damping mechanism 50 includes a fixed shaft 52 fixed in the installation groove, a damping ball 51 rotatably sleeved on the fixed shaft 52, and a magnet shell 53 arranged on the circumference of the damping ball 51, and the magnet shell 53 can abut against the buffer groove 441 corresponding to the installation groove. The damping ball 51 of the damping mechanism 50 contacts the magnet rod 44 through the magnet shell 53 on its circumference, and the damping sleeve rod 541 and the damping member 542 inside the damping ball 51 cooperate with the damping groove 511 under the action of the damping spring 543 to form a rotational damping effect. This can more effectively disperse and absorb the impact force, reduce the linear impact on the magnet rod 44, and protect the toolbox from serious impact damage.

[0047] like Figures 8 to 11 As shown, the damping mechanism 50 also includes a damping sleeve rod 541 disposed in the damping ball 51, a damping member 542 disposed outside the damping sleeve rod 541, and a damping spring 543 disposed between the damping member 542 and the damping sleeve rod 541. The damping sleeve rod 541 is fixedly sleeved on the fixed shaft 52. A damping groove 511 is also disposed in the damping ball 51 to engage with the partially round head at the outer end of the damping member 542. A limiting slide groove 512 is also disposed in the damping ball 51. A limiting ring 55 is connected to the end of the damping sleeve rod 541 to engage with the limiting slide groove 512. A rotation damping system is formed by arranging the damping sleeve rod 541 and the damping member 542 in the damping ball 51 and arranging the damping spring 543 between the two. When the protective plate 31 is impacted and pushes the magnet rod 44 downward, the magnet rod 44 will contact the magnet shell 53 on the damping ball 51 and cause the damping ball 51 to rotate on the fixed shaft 52. During the rotation process, the cooperation between the round head of the outer end portion of the damping member 542 and the damping groove 511 and the compression and recovery of the damping spring 543 can further absorb the impact energy and provide a more effective damping effect. The limiting ring 55 slides in the limiting groove 512 in the damping ball 51, ensuring the stability of the damping ball 51 during rotation, avoiding the possible deviation or jamming of the damping mechanism 50 during operation, thereby improving the reliability of the damping effect.

[0048] like Figures 7 to 9 As shown, a first stop ring is arranged on the inner wall of the movable groove 21, and the buffer sleeve 41, the limit seat 42 and the support spring 22 are all located between the first stop ring and the bottom of the inner box 20, and the buffer sleeve 41 cooperates with the first stop ring. The operation and maintenance protection tool box also includes a magnet assembly 70, which is arranged on the limit seat 42, and a second stop ring is arranged on the hole wall of the buffer sleeve 41. The magnet plate 45 is located between the second stop ring and the magnet assembly 70, and the magnet plate 45 can cooperate with the second stop ring. The magnetism of the two surfaces of the magnet plate 45 and the magnet assembly 70 facing each other is the same. The first stop ring is arranged on the inner wall of the movable groove 21 to ensure the stable position of the limit seat 42 and the support spring 22 of the buffer assembly 40, and avoid unnecessary displacement during the impact process. The second stop ring is arranged on the hole wall of the buffer sleeve 41 to limit the movement range of the magnet plate 45, to ensure that when the magnet plate 45 is impacted and pressed down, it will not exceed its designed movement range, and avoid damage to the internal components. The two surfaces of the magnet plate 45 and the magnet assembly 70 that are arranged facing each other have the same magnetic properties. When the protective plate 31 is impacted and forces the magnet plate 45 to move toward the magnet assembly 70, the like-sex repulsive force between the magnets can serve as an additional damping force to further buffer the downward pressure of the magnet plate 45, thereby protecting the tools in the tool box from damage.

[0049] like Figures 8 to 11As shown, the limit seat 42 includes a seat plate and a mounting shaft arranged at the center of the seat plate, the buffer sleeve 41 is connected to the seat plate, and the mounting shaft is provided with a first magnet ring 71, a second magnet ring 72 and a third magnet ring 73 sleeved on the mounting shaft, the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 are stacked in sequence, the first magnet ring 71 is located between the second magnet ring 72 and the magnet plate 45, and the area of ​​the first magnet ring 71 is smaller than the area of ​​the second magnet ring 72, and the area of ​​the second magnet ring 72 is smaller than the area of ​​the third magnet ring 73. The magnet assembly 70 is composed of the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 of different areas, and the progressive increase of the magnet ring area can provide different damping effects. When the protective plate 31 is pressed down, the elastic corrugated rubber ring 62 gradually shrinks to expose different magnet rings. According to the magnitude of the impact force on the protective plate 31, the magnet assembly 70 provides corresponding damping force, thereby realizing adaptive protection against different impact forces.

[0050] like Figures 9 to 14 As shown, the operation and maintenance protection toolbox also includes an adjustment component 60, which includes an adjustment sleeve 61 located outside the magnet assembly 70, an elastic corrugated rubber ring 62 arranged in the adjustment sleeve 61, and a connecting rope 63 connected between the center of the elastic corrugated rubber ring 62 and the magnet plate 45. The buffer sleeve 41 is provided with a guide channel for guiding the connecting rope 63. The elastic corrugated rubber ring 62 has an avoidance state that is gradually compressed from the center to the outside and a shielding state that is gradually stretched from the outside to the center. When the magnet plate 45 moves toward the first magnet ring 71 and pulls the connecting rope 63, the elastic corrugated rubber ring 62 is in an avoidance state to gradually expose the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73. The elastic corrugated rubber ring 62 of the adjustment component 60 can be switched from the shielding state to the avoidance state under the pull of the connecting rope 63, and the exposure degree of the magnet assembly 70 is dynamically adjusted according to the movement of the magnet plate 45, so as to adjust the damping effect between the protective plate 31 and the magnet assembly 70 to meet the protection requirements of different impact forces.

[0051] like Figures 9 to 15 As shown, the elastic corrugated rubber ring 62 includes a plurality of fan-shaped elastic corrugated films arranged along its circumference, a plurality of connecting ropes 63, and the plurality of connecting ropes 63 are connected to the center of the plurality of fan-shaped elastic corrugated films one by one. A fixed spring 64 is arranged in each fan-shaped elastic corrugated film, and the fixed spring 64 applies an elastic force from the outer side of the fan-shaped elastic corrugated film to the center of the circle. The fan-shaped structure of the elastic corrugated rubber ring 62 and the design of the plurality of fan-shaped elastic corrugated films improve its ability to disperse the impact force. The elastic force of the fixed spring 64 ensures the shielding effect of the elastic corrugated rubber ring 62 in a non-impact state, and also ensures that it can be quickly unfolded when impacted to expose the magnet assembly 70, thereby further buffering the impact force.

[0052] like Figures 1 to 8 As shown, the protection assembly 30 also includes an abutment pad 33 arranged at each corner of the protection plate 31, and the second end of each telescopic rod 43 is connected to a corner of the protection plate 31 through the abutment pad 33. There are multiple support springs 22, and the multiple support springs 22 are arranged at intervals along the axis of the movable groove 21, and a limit ring 23 is arranged between two adjacent support springs 22. The abutment pad 33 in the protection assembly 30 increases the buffering effect of the connection between the protection plate 31 and the telescopic rod 43, reducing the damage to the protection plate 31 caused by direct impact. The multi-stage setting of the support spring 22 and the interval design of the limit ring 23 enable the inner box 20 to move more stably when impacted, reducing the vibration and collision of the tools inside the toolbox.

[0053] like Figures 1 to 8 As shown, the protective assembly 30, the buffer assembly 40 and the damping mechanism 50 are all in two groups, one group of the protective assembly 30, one group of the buffer assembly 40 and one group of the damping mechanism 50 are located on the inner box 20, and the other group of the protective assembly 30, another group of the buffer assembly 40 and another group of the damping mechanism 50 are located on the box cover. When the box cover is set on the outer box, the protective plates 31 of the two groups of the protective assembly 30 are arranged opposite to each other. When the box cover is opened from the outer box, the protective plates 31 of the two groups of the protective assembly 30 are unfolded. The protective assembly 30, the buffer assembly 40 and the damping mechanism 50 are respectively arranged in one group on the box body 10 and the box cover. When the box cover is opened or closed, the two groups of components can work together, which not only provides the convenience of opening the tool box, but also ensures that the tool box can provide effective protection in all states, thereby increasing the protective performance and safety of use of the tool box. The protective component 30 is designed to cooperate with the box cover so that when the tool box cover is closed, the protective plate 31 can provide an additional layer of protection to prevent the tool box cover from directly damaging the internal tools when it is subjected to external impact; when the box cover is opened, the protective component 30 can automatically unfold, making it easier for the staff to take the tools, while also protecting the tools from damage by the external environment.

[0054] like Figures 1 to 15 As shown, the working principle of the operation and maintenance protection toolbox of this embodiment is as follows:

[0055] When in use, the box body 10 is opened by unlocking the lock 12. By providing a plurality of partitions in the inner box 20, different tools can be stored separately, effectively solving the problem of a wide variety of tools in on-site metering and maintenance work, reducing the time for finding and borrowing and returning tools, and improving work efficiency; and when the box body 10 is opened, based on the elastic force of the support spring 22, the buffer component 40 and the protective component 30 are pushed upward, so that the protective component 30 and the inner box 20 are separated from each other, and the inner box 20 is automatically opened, which is convenient for the staff to take the metering and maintenance tools.

[0056] Due to the uncontrollable factors in the external environment, when an object accidentally falls toward the box body 10, the protection component 30 is set to make the external collision object contact with the protection plate 31 first, and the cooperation between the protection plate 31 and the elastic rope 32 can achieve the purpose of buffering protection, and the impact force borne by the protection plate 31 can be initially alleviated and offset to achieve the purpose of reducing the impact force; and when the impact force is too large, based on the impact force on the protection plate 31, the protection plate 31 pushes the telescopic rod 43 downward toward the inside of the buffer sleeve 41, and the magnet rod 44 is synchronously driven to move downward under the thrust of the telescopic rod 43. During the downward movement of the magnet rod 44, it will contact with the damping ball 51, and the magnet shell 53 on the outside of the damping ball 51 is in contact with the buffer groove 441 on the outside of the magnet rod 44, and based on the magnetic force of the magnet shell 53 and the buffer groove 441, the magnet rod 44 can be attracted to each other. The downward pressure is damped and relieved, thereby buffering and offsetting the downward pressure of the protective plate 31; because the protective plate 31 drives the magnet rod 44 to move downward, it will drive the damping ball 51 to rotate, thereby achieving the buffering and unloading of the downward pressure of the magnet rod 44, and the damping ball 51 will rotate on the damping sleeve rod 541 while rotating, and the partial round head at the outer end of the damping member 542 is combined with the damping groove 511 on the inner wall of the damping ball 51. By setting the damping groove 511 as the center of the circle, it is beneficial to apply a certain resistance to the rotation of the damping ball 51 during the combination of the damping member 542 and the damping groove 511, thereby damping the rotation of the damping ball 51, and transmitting the resistance to the magnet rod 44, thereby enhancing the protective effect of the protective plate 31, so that the protective plate 31 can further alleviate and offset the impact force, thereby achieving the purpose of effectively protecting the tool.

[0057] In addition, when the protective plate 31 drives the magnet rod 44 to move downward, the magnet rod 44 is used to drive the magnet plate 45 to move downward at the same time. At the same time, the elastic corrugated rubber rings 62 are pulled apart from each other by the connecting rope 63. When the elastic corrugated rubber rings 62 are opened from each other, the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 below will leak out. By setting the opposite side of the magnet plate 45 to the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 to have the same magnetic properties, based on the principle of like magnets repelling each other, the repulsive magnetic force between the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 and the magnet plate 45 can be used to further alleviate and offset the downward pressure of the protective plate 31, and Through this setting, it is possible to adjust the damping based on the downward pressure of the protective plate 31. When the protective plate 31 is hit with a greater force, the protective plate 31 pushes the magnet rod 44 to move downward for a longer distance. At this time, the opening opened by the connecting rope 63 pulling the elastic corrugated rubber ring 62 is larger, and the magnets of the first magnet ring 71, the second magnet ring 72 and the third magnet ring 73 can be used to damp the magnet plate 45, thereby enhancing the damping effect on the magnet plate 45 and the protective plate 31, and vice versa. Moreover, through this setting, more comprehensive and flexible protection can be provided to the tools, so that when encountering accidents or uncontrollable factors, the tools inside the box 10 can be effectively protected from damage, thereby significantly improving the safety and efficiency of metering operation and maintenance work.

[0058] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0059] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0060] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
