When the maintenance door 2 opens the opening 124, the trigger part 41 is separated from the detector 42. The locker provided in this embodiment detects whether the opening 124 is closed by setting a detection mechanism 4. When the trigger part 41 cooperates with the detector 42, the detector 42 outputs a first signal. When the trigger part 41 is separated from the detector 42, the detector 42 outputs a second signal. Therefore, the control mechanism 3 can determine whether the opening 124 is reliably closed according to the signal output by the detector 42, so as to remind the user when the opening 124 is not closed, so that the user can close the maintenance door 2 in time to avoid rainwater flowing into the maintenance compartment 11 through the opening 124, causing damage to the control mechanism 3, and improve the protection of the control mechanism 3. Optionally, in this embodiment, the trigger part 41 is set on the maintenance door 2, and the detector 42 is set on the cabinet 1. In other embodiments, the trigger part 41 can also be set on the cabinet 1, and the detector 42 can be set on the maintenance door 2.

[0038] Optionally, in other embodiments, the detector 42 may also be a photoelectric sensor, which includes a light emitter and a light receiver. When the trigger part 41 cooperates with the photoelectric sensor, the trigger part 41 is located between the light emitter and the light receiver, and the light receiver cannot receive the light emitted by the light emitter. At this time, the photoelectric sensor outputs a first signal. When the trigger part 41 is separated from the photoelectric sensor, the trigger part 41 withdraws from between the light emitter and the light receiver, and the light receiver can receive the light emitted by the light emitter. At this time, the photoelectric sensor outputs a second signal.

[0039] Optionally, in this embodiment, if Figure 4 and Figure 5 As shown, the cabinet 1 also includes a support frame 14, and the support frame 14 includes a bottom plate 141, a first support plate 142 and a second support plate 143, wherein the bottom plate 141 is fixedly connected to the lower surface of the top wall 12, the first support plate 142 and the second support plate 143 are both vertically connected to the bottom plate 141 and extend downward, the first support plate 142 and the second support plate 143 are relatively parallel and spaced, the elastic top rod 422 includes a top rod 401, a compression spring 402 and a retaining ring 403, the top rod 401 is simultaneously plugged with the first support plate 142 and the second support plate 143, an annular groove is provided on the top rod 401, the retaining ring 403 is clamped with the annular groove, and the retaining ring 403 is located at the first A compression spring 402 is sleeved on the push rod 401 between the first support plate 142 and the second support plate 143, and the compression spring 402 is located between the second support plate 143 and the retaining ring 403. Under the pressure of the compression spring 402, the retaining ring 403 abuts against the first support plate 142. At this time, the push rod 401 is in the initial position, and the push rod 401 extends out of the first support plate 142 by a first length. When the trigger part 41 cooperates with the push rod 401, the trigger part 41 drives the push rod 401 to move to the working position, the compression spring 402 is compressed, and the retaining ring 403 is spaced apart from the first support plate 142. At this time, the push rod 401 extends out of the first support plate 142 by a second length, and the second length is less than the first length.

The lock core 513 is rotated using a key to drive the lock tongue 511 to rotate in the first direction or the second direction. By inserting the lock tongue 511 into the lock slot 521, the maintenance door 2 is prevented from moving upward to open the opening 124, thereby reliably locking the position of the maintenance door 2.

[0048] Optionally, in this embodiment, if Figure 7 As shown, the lock slot 521 includes a first slot 501 and a second slot 502 arranged along a first direction, the first slot 501 is connected to the second slot 502, the width of the first slot 501 is d1, the width of the second slot 502 is d2, the thickness of the lock tongue 511 in the width direction of the lock slot 521 is D, and d1>d2≥D. The above arrangement facilitates the lock tongue 511 to be inserted into the wider first slot 501 relatively smoothly, and when the lock tongue 511 continues to move to the second slot 502, the narrower second slot 502 can well limit the position of the lock tongue 511 and prevent the lock tongue 511 from moving upward.

[0049] In this embodiment, if Figure 3 , Figure 6 and Figure 7 As shown, the top wall 12 includes a first wall 121, a second wall 122 and a third wall 123, the first wall 121 and the third wall 123 are both arranged horizontally, the first wall 121 is provided with an opening 120, the third wall 123 is located below the first wall 121 and opposite to the opening 120, the opening 124 is arranged on the third wall 123, the second wall 122 is connected between the first wall 121 and the third wall 123, the maintenance door 2 also includes a flap 23, the flap 23 is connected to the edges of the door panel 21, when the maintenance door 2 closes the opening 124, the door panel 21 is embedded in the opening 120 and is flush with the first wall 121, the flap 23 is opposite to the second wall 122 and abuts against the third wall 123. The above arrangement not only ensures the sealing and reliability of the maintenance door 2 closing the opening 124, but also makes the top of the locker more flat and beautiful.

[0050] In this embodiment, if Figure 3 As shown, the locking portion 52 is fixedly connected to the lower surface of the third wall 123, and the locking portion 52 extends upward from the opening 124, and the lock groove 521 is located between the first wall 121 and the third wall 123. The lock core 513 is installed on the door panel 21, and the lock tongue 511 is located below the door panel 21, so as to ensure that the lock tongue 511 can be inserted into the lock groove 521 when rotating to lock the position of the maintenance door 2, and the second plate 222 of the limiting plate 22 extends into the opening 124 and abuts against the lower surface of the third wall 123 to prevent the maintenance door 2 from being separated from the cabinet 1.

[0051] In this embodiment, if Figure 3 As shown, the cabinet 1 further includes a waterproof wall 13, the lower end of which is connected to the upper surface of the third wall 123, the waterproof wall 13 extends upward, and the waterproof wall 13 is arranged around the opening 124. When the maintenance door 2 closes the opening 124, the door panel 21 closes the opening 124, and the flap 23 is arranged around the waterproof wall 13. The above arrangement allows the maintenance door 2 to be buckled outside the waterproof wall 13, which can prevent rainwater from entering the maintenance compartment 11 through the opening 124, thereby improving the closing effect of the opening 124.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
