[0002] There are different types of door openings for DC charger cabinets on the market, such as single-door, double-door, and triple-door. Each door opening type requires a door lock to be added to the outside of the door panel, so that the corresponding cabinet door can be opened directly from the outside of the charging pile cabinet. However, after the front door of the DC charger is opened, the DC part or control circuit inside the charger can be directly contacted. Therefore, it is necessary to prevent non-professionals from opening the cabinet door to avoid danger. Therefore, in the prior art, the front door of the DC charger is directly locked by a door lock. However, since the DC charger is outdoors for a long time, it is easy to be affected by weather or external forces. Once the door lock is damaged, it cannot be opened in the long run.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art, such as the model and working principle of the connecting rod lock 2, the structure, model and installation method of the door lock 504, etc.

[0035] Example 1

[0036] A DC charger hidden in a door lock, such as Figure 1 , Figure 4 and Figure 5 As shown, the cabinet includes a cabinet body and a front door 1 arranged on the cabinet body, and the cabinet body is also provided with at least one side door 3, as shown in FIG. Figure 3 As shown, a connecting rod lock 2 for opening or closing the main door 1 is arranged inside the cabinet, and when one of the side doors 3 is opened, the connecting rod lock 2 can be exposed, so as to prevent non-professionals from accidentally opening the main door 1. The premise for professionals to open the main door 1 is to open the corresponding side door 3, and then open the exposed connecting rod lock 2, so as to open the main door 1;

[0037] like Figure 5-Figure 8As shown, in order to further ensure the safety of the DC charger, to avoid accidental contact by non-professionals, or children twisting to open the side door 3 out of curiosity or damaging the door lock 504 on the side door 3, and to avoid long-term exposure to weather outdoors so that the door lock 504 on the side door 3 is damaged and cannot be opened, a through hole is opened on the side door 3, and a receiving tube 5 is fixedly arranged on the inner side of the side door 3. One end of the receiving tube 5 is connected to the through hole to form an open end of the receiving tube 5, and the other end of the receiving tube 5 is closed by a partition 508 to form a closed end of the receiving tube 5. A door lock 504 for controlling the opening or closing of the side door 3 is fixedly arranged on the partition 508. The door lock 504 is selected for the door lock 504 commonly used in DC chargers on the market. The model of the door lock 504 is the prior art in terms of installation method, and no further elaboration is made here.

[0038] The inner side wall of the receiving tube 5 is provided with two baffle bars 501 distributed along the circumferential direction of the receiving tube 5 at one end near the opening, and there is a gap between the two baffle bars 501. The distance between the ends of adjacent baffle bars 501 is such that the gap is actually two. The receiving tube 5 is detachably connected with a cover 4 capable of closing the through hole. The cover 4 can be connected to the side door 3 through a connecting rope. The specific connection method is a prior art and will not be described in detail here. The cover 4 is fixedly provided with two convex bars 401 that match the baffle bars 501. The convex bars 401 can pass through the gap, and during the rotation of the cover 4, the convex bars 401 can be correspondingly fitted with the baffle bars 501 to lock the cover 4 in the through hole. When the through hole needs to be closed, the two convex bars 401 are first pushed into the corresponding gaps respectively, and then the cover 4 is rotated to make it move along the through hole toward the receiving tube 5 until the convex bars 401 can be correspondingly fitted with the baffle bars 501. At this time, the cover 4 is locked. When professionals need to unlock the door lock 504 to open the side door 3, they can rotate the cover 4 in the opposite direction to make the convex strip 401 no longer fit the barrier strip 501. When the convex strip 401 rotates to the corresponding gap, the cover 4 can be directly taken out.

[0039] The above is a basic implementation method of the utility model, which can be further improved, optimized and limited on the basis of the above to obtain the following embodiments:
