[0034] The following further elaborates on this application Figure 1-7 in conjunction with the attached drawings.

[0035] An embodiment of this application discloses an easily lockable housing. Refer to Figure 1 , an easily lockable housing includes a housing 1, a front end cover 2 and a locking assembly 3, and the front end cover 2 is locked to one end of the housing 1 through the locking assembly 3.

[0036] Refer to Figure 1 , Figure 2 and Figure 3 , let the end of the housing 1 where it is locked to the front end cover 2 be the front end of the housing 1. The locking assembly 3 includes a rotating column 31, a fixed block 32, a cam 33 and a plurality of equally spaced locks 34. The rotating column 31 is arranged at the center of the front end cover 2. The front end of the rotating column 31 protrudes from the front end cover 2, and the rear end of the rotating column 31 passes through the front end cover 2. When the front end cover 2 is locked to the housing 1, the rear end of the rotating column 31 is located inside the housing 1.

[0037] Refer to Figure 1 , Figure 3 and Figure 4 , in order to enable the rotating column 31 to be fixed when it does not need to rotate, the fixed block 32 is arranged on the front side wall of the rotating column 31 protruding from the front end cover 2. The fixed block 32 is in a "7" shape. An installation slot 311 is opened on the side wall of the rotating column 31 corresponding to the fixed block 32. The installation slot 311 extends along the front end direction of the rotating column 31. A chute 312 is opened at the bottom of the installation slot 311, and the chute 312 also extends along the front end direction of the rotating column 31. A slide block 321 is integrally formed at one end of the fixed block 32 close to the rotating column 31. The slide block 321 moves in the chute 312 and can move along the front end direction of the rotating column 31;

[0038] Refer to Figure 2 , Figure 3 and Figure 4, at one end of the fixed block 32 away from the slider 321, an elastic buckle 322 is welded. A clamping groove 21 for clamping with the elastic buckle 322 is correspondingly formed at the front end cover 2. By sliding the fixed block 32, the elastic buckle 322 can be both clamped with the clamping groove 21 and disconnected from the clamping groove 21. When it is necessary to fix the rotating column 31 and prevent it from rotating, it can be achieved by clamping the elastic buckle 322 with the clamping groove 21. When the rotating column 31 needs to rotate, move the fixed block 32 along the front end direction of the rotating column 31, and the elastic buckle 322 can be pulled out of the clamping groove 21. The clamping groove 21 includes a locking groove 211 and an unlocking groove 212.

[0039] Refer to Figure 2 and Figure 6 , the cam 33 is welded to the rear end of the rotating column 31. A plurality of equally spaced convex arc blocks 331 are integrally formed on the outer side wall of the cam 33. In this embodiment, according to the size of the cam 33, three equally spaced convex arc blocks 331 are preferably provided on the outer side wall of the cam 33. The convex arc blocks 331 are divided into a locking portion 3311 and an unlocking portion 3312. The locking portion 3311 and the unlocking portion 3312 are connected. And on the cam 33, the locking portion 3311 protrudes from the unlocking portion 3312, that is, the shortest distance from the outer side wall of the locking portion 3311 to the center point of the cam 33 is greater than the longest distance from the outer side wall of the unlocking portion 3312 to the center point of the cam 33.

[0040] Refer to Figure 1 and Figure 7 , a plurality of equally spaced hinge members 11 are welded on the outer side wall of the front end of the housing 1. The lock 34 is hinged to the outer side wall of the housing 1 through the hinge member 11. Since the lock 34 cooperates with the cam 33 to lock and unlock the front end cover 2 and the housing 1, in this embodiment, three equally spaced hinge members 11 are welded on the outer side wall of the front end of the housing 1, and a lock 34 is hinged on each hinge member 11. The hinge member 11 specifically includes a pair of ear pieces 111 and a pin shaft 112. The lock 34 is hinged between a pair of ear pieces 111 through the pin shaft 112.

[0041] Refer to Figure 1 , Figure 2 and Figure 6 , a resisting column 341 is welded on the side wall of the lock 34 near the rear end and facing the housing 1. The end of the resisting column 341 away from being welded to the lock 34 passes through the housing 1, and the end of the resisting column 341 passing through the housing 1 can be in contact with the convex arc block 331. When the resisting column 341 is in contact with the locking portion 3311, the resisting column 341 is pushed to move outside the side wall of the housing 1, that is, the rear end part of the lock 34 is pushed to move away from the side wall of the housing 1. At this time, the front end part of the lock 34 moves towards the side wall of the front end cover 2 and finally clamps on the front end cover 2, so that the front end cover 2 and the housing 1 are locked;

[0042] Referring to Figure 1 、 Figure 2 and Figure 6 When the abutting post 341 abuts against the unlocking portion 3312, the abutting post 341 is driven to move towards the inside of the housing 1, that is, the rear end portion of the lock catch 34 is driven to move towards the side wall of the housing 1. At this time, the front end portion of the lock catch 34 moves in the direction away from the side wall of the front end cover 2 and finally leaves the front end cover 2, so that the front end cover 2 is unlocked from the housing 1.

[0043] Referring to Figure 2 and Figure 6 In order to prevent the cam 33 from continuing to rotate and disconnecting the abutting post 341 from the locking portion 3311 when the abutting post 341 abuts against the side wall of the locking portion 3311 away from the end connected to the unlocking portion 3312 when the cam 33 is rotated by the rotating post 31, a limiting block 332 is integrally formed at the end of the locking portion 3311 away from the end connected to the unlocking portion 3312.

[0044] Referring to Figure 3 、 Figure 5 and Figure 6 The locking groove 211 is arranged opposite to the end of the locking portion 3311 away from the end connected to the unlocking portion 3312, and the unlocking groove 212 is arranged opposite to the end of the unlocking portion 3312 away from the end connected to the locking portion 3311. When the cam 33 rotates until the limiting block 332 abuts against the abutting post 341, the elastic latch can be inserted into the locking groove 211 to fix the rotating post 31 and stop driving the cam 33 to rotate. When the elastic buckle 322 is pulled out of the locking groove 211, when the cam 33 rotates until the unlocking groove 212 abuts against the abutting post 341 and the lock catch 34 no longer locks the front end cover 2 to the housing 1, the elastic buckle 322 can be inserted into the unlocking groove 212 to fix the rotating post 31 and stop driving the cam 33 to rotate.

[0045] The implementation principle of an easily lockable housing in an embodiment of the present application is as follows: When the front end cover 2 needs to be locked to the housing 1, first place the front end cover 2 at the front end of the housing 1 and rotate the rotating post 31 protruding from the front end cover 2. When rotating until the limiting block 332 abuts against the abutting post 341, the abutting post 341 is pushed to move towards the outside of the housing 1. At this time, the rear end portion of the lock catch 34 is also driven by the abutting post 341 to move in the direction away from the side wall of the housing 1, and the front end portion of the lock catch 34 moves towards the front end cover 2, so that the lock catch 34 locks the front end cover 2 to the housing 1. In order to fix the rotating post 31 on the front end cover 2 and stop it from rotating, the elastic buckle 322 on the fixing block 32 is aligned with the locking groove 211 for clamping;

[0046] When it is necessary to repair the inside of the casing and unlock the front end cover 2 and the casing 1, first pull out the elastic buckle 322 from the locking groove 211, and then rotate the rotating column 31 protruding from the front end cover 2. At this time, the rotating direction of the rotating column 31 is opposite to the direction of locking the front end cover 2 and the casing 1, so that the abutting column 341 gradually abuts against the unlocking portion 3312. The rear end portion of the lock 34 moves towards the inside of the casing 1 under the drive of the abutting column 341, and the front end portion of the lock 34 moves away from the front end cover 2, so that the lock 34 no longer locks the front end cover 2 and the casing 1. In order to fix the rotating column 31 on the front end cover 2, align the elastic buckle 322 with the unlocking groove 212 for clamping. At this time, the front end cover 2 can be removed to unlock it from the casing 1.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
