[0030] Embodiment 1

[0031] Referring to Figures 1 to 7 , this is the first embodiment of the present utility model. This embodiment provides a lock 202c, which can achieve the effect that the box door 102 can be unlocked by a key and held in an open state, and then when the box door 102 needs to be opened, the lever 202b can be toggled upward to open the box door 102, and the box door 102 can be easily closed and automatically locked. It includes an installation unit 100, which includes a box body 101 and a box door 102 provided at the front of the box body 101; a reset unit 200, which includes a fixed seat 201 provided on the box door 102, a fixed component 202 provided on the fixed seat 201, a rotating component 203 provided on the fixed seat 201, a resilient component 204 provided on the rotating component 203, a limiting component 205 provided on the fixed component 202, and a pressing component 206 provided on the limiting component 205.

[0032] Specifically, the box door 102 is connected to the box body 101 through hinges on both sides. A fixed seat 201 is provided on the box door 102, and a lock 202c is installed on the fixed seat 201. By inserting the correct key into the keyhole of the lock 202c, the lock pin in the lock 202c can be rotated to unlock the box door 102. A receiving groove 202a is opened on the front surface of the fixed seat 201. Rotating grooves 203a are opened on both sides near the upper end of the inner wall of the receiving groove 202a. A connecting rod 203b is rotatably connected in the rotating groove 203a. A lever 202b is fixedly connected between the two connecting rods 203b. This enables the lever 202b to be rotatably connected in the receiving groove 202a through the connecting rod 203b. And a round hole 202d is opened on the front surface of the lever 202b, and the diameter of the round hole 202d is larger than the diameter of the lock 202c. This enables the lever 202b to pass through the lock 202c through the round hole 202d and be received in the receiving groove 202a.

[0033] Further, an activity groove 301b is formed in the inner wall of the receiving groove 202a. A rotating member 301a is arranged outside the upper end of the lever 202b. The rotating member 301a is rotatably connected to the activity groove 301b. Sliding grooves 302a are formed at both sides of the inner wall of the activity groove 301b. The sliding grooves 302a are cylindrical. A sliding rod 302b is horizontally and slidably connected to the inner wall thereof. A trapezoidal groove 303a is formed at a position close to the center of the outer wall of the sliding rod 302b. And an inclined pressing surface 303b is formed at one side of the inner wall thereof. The pressing surface 303b cooperates with the rotating member 301a. A positioning groove 304c is formed at the bottom of the inner wall of the other sliding groove 302a. The positioning groove 304c is movably connected with a limiting ring 304a through a third spring 304b. And the limiting ring 304a is fixedly connected to one end of the movable rod. When the sliding rod 302b moves, the limiting ring 304a can guide the moving track of the sliding rod 302b. And through the elastic potential energy of the third spring 304b, the limiting ring 304a can provide a driving force for the sliding rod 302b.

[0034] During use, the lock 202c on the box door 102 can lock the box door 102 for a long time, which can enhance the safety of the distribution box. The staff can open the lock 202c of the box door 102 with a key. At this time, the box door 102 is in an open state. At this time, the lever 202b in the receiving groove 202a can be toggled upward. The lever 202b will drive the rotating member 301a to rotate in the rotating groove 203a. The rotating member 301a will rotate into the trapezoidal groove 303a. And the edge of the rotating member 301a will contact the pressing surface 303b, applying a downward pressure thereto, thereby causing the sliding rod 302b to move in one direction and applying a pressure in one direction to the third spring 304b to store elastic potential energy. As the sliding rod 302b moves in one direction, the other end thereof will disengage from the operation hole 302c until it disengages. At this time, the lever 202b can be held and pulled forward to open the box door 102. Similarly, when the box door 102 needs to be temporarily closed, the lever 202b is toggled upward and then the box door 102 is pushed backward to temporarily close the box door 102. When the staff needs to leave, they only need to close the box door 102 without having to lock it again each time, thus improving the operation convenience. When the box door 102 does not need to be opened temporarily, the lock 202c on the box door 102 can be locked with a key. This device is used in scenarios where the box door needs to be opened and closed frequently, which can simplify the operation process, improve work efficiency, and ensure the safety of the distribution box.

[0035] Embodiment 2

[0036] Refer to Figures 1 to 3, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a limiting component 205 for the lock 202c, solving the problem that the shift lever 202b cannot be fixed when stored in the receiving groove 202a. The limiting component 205 includes a limiting groove 205a provided on the outer side of the shift lever 202b, a telescopic groove 205b provided on the inner wall of the receiving groove 202a, a second spring 205c provided at the bottom of the telescopic groove 205b, and a limiting block 205d provided on the second spring 205c. A telescopic groove 205b is provided at the lower side position of the inner wall of the receiving groove 202a. The limiting block 205d is elastically connected in the telescopic groove 205b through the elastic force of the second spring 205c. A limiting groove 205a is provided at a position near the lower end on the outside of the shift lever 202b. The positions of the limiting groove 205a and the telescopic groove 205b match, and the upper end of the limiting block 205d is limited in the limiting groove 205a.

[0037] Further, an arc surface 206a is provided at a position near the lower end of the front edge of the shift lever 202b. The arc surface 206a is an inclined arc surface 206a, presenting an "A" shape at the upper end of the limiting block 205d. The two side inclined surfaces thereof are inclined surfaces 206b, and the inclined surfaces 206b cooperate with the arc surface 206a. A limiting surface 206c is provided on the inner wall of the limiting groove 205a, and the limiting surface 206c is parallel and cooperates with the rear surface of the limiting block 205d.

[0038] During use, when the shift lever 202b does not need to be operated, the shift lever 202b can be pressed into the receiving groove 202a. The rear edge of the shift lever 202b will exert an extrusion force on the front inclined surface 206b of the limiting block 205d, causing the limiting block 205d to move downward and exert a downward pressure on the second spring 205c, so that the second spring 205c stores elastic potential energy. As the shift lever 202b moves, the rear edge of the shift lever 202b no longer contacts the inclined surface 206b. The driving force applied by the second spring 205c pushes the limiting block 205d upward, so that the limiting block 205d is limited in the limiting groove 205a. At this time, the shift lever 202b cannot be separated from the receiving groove 202a.

[0039] Embodiment 3

[0040] Refer to Figures 5 to 6, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a lock 202c, which solves the problem that the lever 202b cannot automatically pop out from the receiving groove 202a after being unlocked. It includes a rotating assembly 203 including an L-shaped block 203c on a connecting rod 203b. The L-shaped block 203c is in an "L" shape, and its inner side is in an arc shape. A rectangular groove 204a is opened at 45 degrees on the inner wall of the rotating groove 203a. A sliding seat 204c is elastically connected to the rectangular groove 204a through a spring 204b, and a roller 204d is rotatably connected to the sliding seat 204c through a rotating shaft. The sliding seat 204c pushes the roller 204d to fit the inner side of the L-shaped block 203c through a spring 204b.

[0041] When in use, when the roller 204d is in contact with the center of the inner side of the L-shaped block 203c, the lever 202b should be rotated 45 degrees clockwise with the connecting rod 203b as the center. When the lever 202b needs to be stored, we can press the lever 202b, and the lever 202b will rotate counterclockwise with the connecting rod 203b as the center. The lever 202b will drive the inner side of the other side of the L-shaped block 203c on both sides to contact the roller 204d and exert force on it to the rectangular groove 2 04a bottom direction pressure, thereby causing roller 204d to slide downward through sliding seat 204c, and exerting downward pressure on spring 1 204b, spring 1 204b contracts downward until limit block 205d is limited in limit slot 205a, and no staff applies force to lever 202b, the elastic potential energy stored in spring 1 204b will exert an upward thrust on sliding seat 204c, waiting for rebound, because limit block 205d is limited in limit slot 205a, at this moment The limiting surface 206c and the rear surface of the limiting block 205d are in contact with each other because they are both vertical planes and conflict with each other, so the lever 202b cannot automatically rebound. At this time, the lever 202b needs to be pressed again, and the arc surface 206a on the front side surface of the lever 202b will apply downward pressure to the front inclined surface 206b of the limiting block 205d, and the front arc surface 206a of the lever 202b will pass over the limiting block 205d, and the limiting block 205d will be pushed back by the elastic force of the spring 205c. The lever 202b can move upward and resist against the front side of the lever 202b. Since the elastic potential energy of the spring 1 204b always exists, the lever 202b will rotate clockwise, and the arc surface 206a of the lever 202b will exert downward pressure on the rear inclined surface 206b of the limit block 205d, so that the lever 202b can pass over the limit block 205d and reset. Similarly, when the sliding rod 302b is separated from the operating hole 302c, the L-shaped block 203c can also drive the lever 202b to reset.
