Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a locking device for a distribution box door. Background Art

[0002] A distribution box is an enclosed or semi-enclosed metal cabinet assembled with switchgear, measuring instruments, protective devices, and auxiliary equipment according to electrical wiring requirements. Existing distribution box doors and cabinets are often secured with latches. Because the latches are exposed to the elements, the door can accidentally open during operation if the operator or passersby accidentally snag the handle.

[0003] Therefore, the traditional distribution box can be improved so that it can have the effect of locking the box door, effectively preventing the box door from being accidentally opened. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and to propose a locking device for a distribution box door.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A locking device for a distribution box door comprises a box body and a door body, wherein a side block is fixed on the box body, a fixed block is fixed on the door body, a screw groove is provided on the fixed block, a rotating rod is provided on the side block for sliding connection, and a screw block connected to the screw groove by a thread is fixed on the rotating rod, and a limiting piece for limiting the rotating rod is provided on the fixed block.

[0007] Preferably, the limiting member includes a fixed plate fixed on the rotating rod, a fixed rod fixed on the side block, and the fixed rod is slidably connected to the circular hole opened on the bent plate, a through rod is fixed on the bent plate, and a through hole adapted to the through rod is opened on the fixed plate, and a sliding hole slidably connected to the rotating rod is opened on the bent plate.

[0008] Preferably, the through holes are distributed in a plurality of equal angles on the circumference of the fixed disk with the center of the fixed disk as the axis.

[0009] Preferably, a spring is sleeved on the rotating rod, and one end of the spring abuts against the bent plate, and the other end abuts against the side block.

[0010] Preferably, after the screw block is separated from the screw groove, it abuts against the side wall of the side block. At this time, the door body can rotate and open and close normally, and the circular hole of the bent plate is still slidably connected to the fixing rod.

[0011] Preferably, an elastic gasket protrudes from the portion where the bent plate abuts against the side block.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] 1. The present application rotates the rotating rod by a handle so that the screw block at the end of the rotating rod is connected to the screw groove on the fixed block through a threaded connection. At this time, the door body and the box body are fixed as one. Therefore, even if the rotating rod is pulled, it will not easily rotate and the screw block will not separate from the screw groove. Therefore, the connection between the door body and the box body is relatively more stable, avoiding the phenomenon of accidental opening of the door body.

[0014] 2. In this application, a through-rod is passed through the through-hole on the bent plate. At this time, the rotating rod cannot be rotated under the restriction of the through-rod. At this time, the box body and the door body can be fixed together more stably, effectively avoiding the door body from rotating open due to accidental force. The connection between the box body and the door body is more stable, and the door body and the box body will not be easily separated even if subjected to external force.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] This utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A locking device for a distribution box door includes a box body 1 and a door body 2. The box body 1 and the door body 2 are directly referenced from the prior art and are not described in detail here. A side block 5 is fixed to the box body 1, and a fixed block 3 is fixed to the door body 2. The fixed block 3 is provided with a screw groove 4. A rotating rod 7 is provided on the side block 5 for sliding connection, and a screw block 8 is fixed on the rotating rod 7 and is threadedly connected to the screw groove 4. A stopper is provided on the fixed block 3 for limiting the position of the rotating rod 7. By rotating the rotating rod 7, the screw block 8 can be threadedly connected to the screw groove 4 provided on the fixed block 3, thereby fixing the door body 2 and the box body 1 as a whole. Even if the rotating rod 7 is pulled, the screw block 8 will not be separated from the screw groove 4.

[0024] Example 2:

[0025] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the limiting member includes a fixed plate 10 fixed to the rotating rod 7, a fixed rod 6 fixed to the side block 5, and the fixed rod 6 is slidably connected to the circular hole 13 opened in the bent plate 12. A penetrating rod 15 is fixed to the bent plate 12, and a through hole 11 is opened in the fixed plate 10 to match the penetrating rod 15. The bent plate 12 is provided with a sliding hole 14 that is slidably connected to the rotating rod 7. Multiple through holes 11 are distributed at equal angles around the circumference of the fixed plate 10 with the center of the fixed plate 10 as the axis.

[0026] A spring 16 is sleeved on the rotating rod 7, with one end of the spring 16 abutting against the bent plate 12 and the other end abutting against the side block 5. Under the elastic force of the spring 16, the bent plate 12 can be moved closer to the fixed plate 10. After the screw block 8 is released from the screw groove 4, it abuts against the side wall of the side block 5. At this time, the door body 2 can rotate and open and close normally, and the circular hole 13 of the bent plate 12 is still slidably connected to the fixed rod 6. The portion of the bent plate 12 abutting the side block 5 has an elastic gasket protruding.

[0027] A handle 9 is fixed on the fixing plate 10 , and the handle 9 can be used to more conveniently control the rotation of the rotating rod 7 , so that the screw block 8 and the screw groove 4 are connected through threads.

[0028] In summary, when the door body 2 provided in this embodiment is fixed to the box body 1:

[0029] Under the elastic force of spring 16, fixed plate 10 moves away from side block 5 until screw block 8 contacts the side wall of side block 5. At this point, door body 2 can be rotated to fit into housing 1. Then, bent plate 12 can be pushed to move until rod 15 on bent plate 12 disengages through hole 11 in fixed plate 10. Rotating rod 7 is rotated by handle 9, so that screw block 8 at the end of rotating rod 7 is threadedly connected to screw groove 4 in fixed block 3.

[0030] At this time, the door body 2 is fixed with the box body 1 as a whole, the pushing force on the bending plate 12 is loosened, under the elastic force of the spring 16, the bending plate 12 moves to be close to the fixed disc 10, and the penetrating rod 15 on the bending plate 12 penetrates the through hole 11, at this time, the rotating rod 7 cannot rotate under the force limitation of the penetrating rod 15. At this time, the box body 1 and the door body 2 can be more stably fixed as a whole, and the door body 2 is effectively prevented from rotating and opening accidentally.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Accordingly, the present application is not to be limited to the embodiments shown herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
