[0009] As a preferred embodiment of this utility model, the outer edges of both the movable shell and the box are fixedly fitted with limit posts, and the inner wall of the buffer spring is movably connected to the limit posts.

[0010] As a preferred embodiment of this utility model, a magnet is fixedly mounted on the outer edge of the movable housing, and a magnet is fixedly mounted on the outer edge of the outer compartment door.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This dual power switching box with a protective shell, through the setting of an outer door, a movable shell, a hollow protective shell and a buffer spring, when the outer door is impacted, the impact force will cause the movable shell to slide in the hollow protective shell, and the buffer spring will buffer the impact force, thus protecting the box door, thereby solving the problem that the box door of the existing dual power switching box does not have a protective device.

[0013] 2. This dual power switching box with a protective shell uses top and bottom locking plates to fix the top and bottom corners of the door, making it difficult to pry open the top and bottom of the door. This solves the problem that existing door lock plates are in the middle and the top and bottom of the door are not fixed, making it easy to pry open the top and bottom of the door.

[0014] 3. This dual power supply switching box with a protective shell, when the lock cylinder is rotated clockwise, the top connecting rod pushes the top lock plate to rotate, and the bottom connecting rod pushes the bottom lock plate to rotate, so that the top lock plate and the bottom lock plate can rotate synchronously with the middle lock plate.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 6 A dual-power switching box with a protective casing includes a box body 1. A door 2 is located on the right side of the box body 1. A lock cylinder 21 is fixedly mounted on the outer wall of the door 2. A middle locking plate 22 is installed at the bottom of the lock cylinder 21, a top locking plate 24 is located at the top of the middle locking plate 22, and a bottom locking plate 23 is located at the bottom of the middle locking plate 22. The bottom of the middle locking plate 22 and the bottom of the bottom locking plate 23 are movably connected by a bottom connecting rod 25. The middle locking plate 22 and the top locking plate 24 are movably connected by a top connecting rod 26. By unlocking the lock cylinder 21 and then rotating it clockwise, the lock cylinder 21 changes from a horizontal to a vertical position. When the lock cylinder 21 rotates, the middle locking plate 22 pushes the top locking plate 24 through the top connecting rod 26. The locking plate 24 rotates, and at the same time, the bottom locking plate 23 is pushed to rotate through the bottom connecting rod 25, so that the bottom locking plate 23 and the top locking plate 24 rotate synchronously with the middle locking plate 22. The setting of the top locking plate 24 and the bottom locking plate 23 makes it impossible for the device to be pried open by the top and bottom corners of the door 2, thus improving the safety of the device. The outer wall of the box 1 is fixedly equipped with a hollow protective shell 3, and the inner wall of the hollow protective shell 3 is slidably connected to a movable shell 4. The outer edge of the movable shell 4 is movably connected to an outer door 5. The setting of the hollow protective shell 3, the movable shell 4, and the outer door 5 can protect the box 1 and prevent damage to the box 1.

[0024] In a preferred embodiment, the top connecting rod 26 is located on the left side of the lock cylinder 21, and the bottom connecting rod 25 is located on the right side of the lock cylinder 21. When the middle lock plate 22 rotates, the positions of the connection points of the bottom connecting rod 25 and the top connecting rod 26 on the middle lock plate 22 will change from a horizontal state to a vertical state. At this time, the top connecting rod 26 and the bottom connecting rod 25 become a straight line. When the middle lock plate 22 is in a horizontal state, the lock cylinder 21 cannot be unlocked by rotating it counterclockwise.

[0025] In a preferred embodiment, the bottom of the bottom locking piece 23 is rotatably connected to the bottom of the bottom bracket 29, the bottom of the middle locking piece 22 is rotatably connected to the bottom of the middle bracket 27, and the bottom of the top locking piece 24 is rotatably connected to the bottom of the top bracket 28. The bottom bracket 29, the middle bracket 27, and the top bracket 28 are all fixedly mounted on the door 2. The bottom locking piece 23 rotates on the bottom bracket 29, the middle locking piece 22 rotates on the middle bracket 27, and the top locking piece 24 rotates on the top bracket 28. The top bracket 28, the bottom bracket 29, and the middle bracket 27 respectively limit the movement of the top locking piece 24, the bottom locking piece 23, and the middle locking piece 22.

[0026] In a preferred embodiment, a buffer spring 7 is provided between the movable shell 4 and the box 1. Two buffer springs 7 are provided on each of the four sides of the box 1. With the buffer springs 7, when the outer door 5 is hit, the movable shell 4 slides in the hollow protective shell 3, and the impact force is buffered by the buffer springs 7, thus protecting the box door 2 through the outer door 5.

[0027] In a preferred embodiment, the outer edges of both the movable housing 4 and the box 1 are fixedly fitted with limit posts 6. The inner wall of the buffer spring 7 is movably connected to the limit posts 6. The limit posts 6 play a positioning role for the buffer spring 7, so that the buffer spring 7 will not be displaced, thereby improving the stability of the buffer spring 7.

[0028] In a preferred embodiment, a magnet 41 is fixedly mounted on the outer edge of the movable housing 4, and a magnet 51 is fixedly mounted on the outer edge of the outer door 5. The outer door 5 and the movable housing 4 are connected by the magnet 51 and the magnet 41. The magnet 51 and the magnet 41 can attract each other, so that the outer door 5 can be opened quickly.

[0029] Working principle: When the outer door 5 is impacted, the impact force causes the movable housing 4 to slide within the hollow protective shell 3. The impact force is buffered by the buffer spring 7, thus protecting the door 2. The movable housing 4 and the hollow protective shell 3 protect the box body 1. The lock cylinder 21 is unlocked, and then rotated 90° clockwise. At this time, the top connecting rod 26 pushes the top lock plate 24 to rotate, and the bottom connecting rod 25 pushes the bottom lock plate 23 to rotate, so that the top lock plate 24 and the bottom lock plate 23 can rotate synchronously with the middle lock plate 22. Through the setting of the top lock plate 24 and the bottom lock plate 23, the top and bottom corners of the door 2 can be fixed, making it difficult for the top and bottom corners of the door 2 to be pried open.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
