[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0020] Example 1

[0021] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and provides a locking device for a double-door switch cabinet. The locking device for the double-door switch cabinet includes a main body component 100 and a locking component 200. The two can cooperate to directly limit the door body after the door body is closed, without the need to install columns.

[0022] The main assembly 100 includes a switch cabinet 101 , a door body 102 and a handle 103 . The door body 102 is disposed on one side of the switch cabinet 101 , and the handle 103 is fixed on one side of the door body 102 .

[0023] The switch cabinet 101 is a device used to install, protect and connect electrical equipment. It is usually made of metal or plastic and has a protective function. It is used to store electrical equipment and to separate, isolate and protect electrical equipment. There are two door bodies 102, both located on one side of the switch cabinet 101. The door body 102 is often used to facilitate personnel to operate, maintain and overhaul the switch cabinet 101. The door body 102 can be opened or closed to facilitate personnel to enter the switch cabinet 101 to perform necessary operations. The door body 102 can also play a protective role to prevent external debris from entering the switch cabinet 101, ensuring the safe operation of the electrical equipment in the switch cabinet 101. There are two handles 103, both fixed on one side of the door body 102. The setting of the handle 103 facilitates the user to open or close the door body 102.

[0024] The locking assembly 200 is disposed on the door body 102 , and includes a locking member 201 . The locking member 201 is disposed on the door body 102 .

[0025] After the door 102 of the switch cabinet 101 is closed, in order to prevent the door 102 from deforming or opening by itself, the door 102 can be limited by setting the locking member 201, thereby preventing the door 102 from closing, deforming or opening by itself.

[0026] Example 2

[0027] Reference Figure 1 to Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0028] Specifically, the locking member 201 includes a locking plate 201a and a locking frame 201b. The locking plate 201a is disposed on one side of the door body 102, and the locking frame 201b is disposed on one side of the locking plate 201a.

[0029] The lock frame 201b is provided with a lock hole corresponding to the lock plate 201a. After the door body 102 is closed, the lock plate 201a is rotated to make the lock plate 201a enter the lock hole on one side of the lock frame 201b, thereby limiting the door body 102 and preventing the door body 102 from opening by itself.

[0030] Specifically, the locking member 201 further includes a rotating rod 201c and a rotating block 201d. The rotating rod 201c is plugged into one side of the locking plate 201a, and the rotating block 201d is fixed to one side of the rotating rod 201c.

[0031] When the lock plate 201a needs to be rotated, the rotating block 201d is rotated. The rotation of the rotating block 201d can drive the rotating rod 201c to rotate. At this time, the lock plate 201a can be rotated by rotating the rotating rod 201c. A key slot is provided at the other end of the rotating block 201d. The worker can insert the key into the key slot on the rotating block 201d to rotate the rotating block 201d or limit the rotating block 201d. The key slot on the rotating block 201d belongs to the prior art, so it is not elaborated in detail. The rotating block 201d is plugged into one side of the door body 102, and the rotating block 201d is movably connected to the door body 102.

[0032] Specifically, the locking member 201 further includes a supporting sleeve 201e, which is sleeved on the outside of the rotating block 201d, and the supporting sleeve 201e and the rotating block 201d are movably connected.

[0033] The support sleeve 201e can be provided to limit the rotating block 201d in rotation, thereby preventing the rotating block 201d from deviating during rotation.

[0034] Specifically, the locking member 201 further includes a fixing plate 201f and a bolt 201g. The fixing plate 201f is fixed to one side of the door body 102. The bolt 201g is inserted into one side of the fixing plate 201f. The bolt 201g and the fixing plate 201f are threadedly connected.

[0035] The fixed plate 201f is fixed to one side of the support sleeve 201e, and the fixed plate 201f is sleeved on one side of the rotating block 201d. The fixed plate 201f is movably connected to the rotating block 201d. The setting of the fixed plate 201f can support the support sleeve 201e and the rotating block 201d to prevent the rotating block 201d from shifting. There are two bolts 201g, both of which are inserted into one side of the door body 102. The bolts 201g are threadedly connected to the door body 102. The setting of the bolts 201g can fix the fixed plate 201f to one side of the door body 102.

[0036] When in use, after closing the door body 102, it is necessary to limit the door body 102. First, insert the key into the key slot on the rotating block 201d, and then turn the key. The key drives the rotating block 201d to rotate. The rotation of the rotating block 201d will drive the rotating rod 201c to rotate. At this time, the lock plate 201a can be rotated by rotating the rotating rod 201c. By rotating the lock plate 201a to the lock hole set on the lock frame 201b, the door body 102 can be limited to prevent the door body 102 from opening by itself. Then the key can be pulled out. When the door body 102 needs to be opened again, the limit of the rotating block 201d can be released by simply inserting the key into the key slot on the rotating block 201d.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
