[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 6 , an electromagnetic drive device for a cabinet-type gas fire extinguishing device, including an outer shell 1, an inner shell 2 is fixedly assembled on the inner wall of the outer shell 1, a fixed shell 3 is fixedly assembled on the top of the inner shell 2, a connector 4 is fixedly assembled on the outer wall of the outer shell 1, a plug 5 is inserted into the inner wall of the connector 4, a positive terminal 6 and a negative terminal 7 are arranged in the inner cavity of the plug 5, a power-off shell 8 is fixedly assembled on the top of the plug 5, a positive cylinder 13 and a negative cylinder 14 are arranged in the inner cavity of the power-off shell 8, a positive head 17 and a negative head 18 are respectively slidably connected to the inner walls of the positive cylinder 13 and the negative cylinder 14, a slide groove 9 is opened at the bottom of the power-off shell 8, and a power-off plate 19 is slidably connected to the inner wall of the slide groove 9. Through the arrangement of the positive terminal 6, the negative terminal 7, the positive head 17 and the negative head 18, when the power-off plate 19 is inserted between the positive terminal 6, the negative terminal 7, the positive head 17 and the negative head 18, the positive terminal 6, the negative terminal 7, the positive head 17 and the negative head 18 are separated, so that the plug 5 can be powered off without unplugging the plug 5 from the connector 4, making the power-off easier.

[0023] In a preferred implementation manner, a first vertical hole 11 and a second vertical hole 12 are opened in the inner cavity of the power-off shell 8, the positive cylinder 13 and the negative cylinder 14 are respectively installed in the first vertical hole 11 and the second vertical hole 12, and the first vertical hole 11 and the second vertical hole 12 respectively correspond to the positive terminal 6 and the negative terminal 7, so that the positive terminal 6, the negative terminal 7, the positive head 17 and the negative head 18 can be in contact to conduct electricity. The power-off shell 8 plays an insulating role for the positive cylinder 13 and the negative cylinder 14, so that the power-off shell 8 does not conduct electricity, improving the rationality of the device.

[0024] In a preferred embodiment, a limiting groove 10 is provided on the inner wall of the slide groove 9, and the inner wall of the limiting groove 10 is slidably connected to a limiting block 20. The limiting block 20 is fixedly assembled on the power-off plate 19. By setting the limiting block 20, when the power-off plate 19 slides on the slide groove 9, the limiting block 20 will slide on the limiting groove 10. The length of the limiting groove 10 is longer than the diameter of the positive head 17 and the negative head 18, so that when the power-off plate 19 is not in contact with the positive head 17 and the negative head 18, the limiting block 20 will limit the power-off plate 19, so that the power-off plate 19 will not separate from the power-off shell 8, thereby improving the stability of the device.

[0025] In a preferred embodiment, the power-off plate 19 is made of plastic, and one end of the power-off plate 19 close to the positive electrode column 6 and the negative electrode column 7 is an inclined surface. The good conductivity of plastic is utilized so that the power-off plate 19 separates the positive electrode head 17 from the negative electrode head 18 and the positive electrode column 6 from the negative electrode column 7, so that no electricity can be supplied between the positive electrode head 17 from the negative electrode head 18 and the positive electrode column 6 from the negative electrode column 7.

[0026] In a preferred embodiment, the inner cavities of the positive electrode cylinder 13 and the negative electrode cylinder 14 are respectively installed with spring one 15 and spring two 16, and the spring one 15 and spring two 16 are respectively located above the positive electrode head 17 and the negative electrode head 18. When the power-off plate 19 is not in contact with the positive electrode head 17 and the negative electrode head 18, the positive electrode head 17 and the negative electrode head 18 are pushed downward by the elastic force of the spring one 15 and the spring two 16, so that the positive electrode head 17 and the negative electrode head 18 are respectively in contact with the positive electrode column 6 and the negative electrode column 7, so that the plug 5 can be energized.

[0027] In a preferred embodiment, a contact ring 21 is fixedly mounted on the outer wall of the bottom of the inner shell 2, and the outer edge of the contact ring 21 is rotatably connected to a connecting internal threaded sleeve 22, and the inner wall of the connecting internal threaded sleeve 22 is threadedly connected to a heptafluoropropane tank body 23. By placing the contact ring 21 above the heptafluoropropane tank body 23 and then rotating the connecting internal threaded sleeve 22, the threads on the connecting internal threaded sleeve 22 are engaged with the threads on the heptafluoropropane tank body 23, so that the device does not need to be rotated as a whole during installation, which facilitates the positioning of the connector 4.

[0028] Working principle: When in use, the contact ring 21 is brought into contact with the heptafluoropropane tank 23. Subsequently, by turning the connecting internal thread sleeve 22, the thread on the connecting internal thread sleeve 22 meshes with the thread on the heptafluoropropane tank 23. When the connecting internal thread sleeve 22 cannot be turned anymore, the installation is completed at this time. Then, the plug 5 is inserted into the connector 4. When it is necessary to detect the fire detector, the plug 5 needs to be powered off at this time. By pushing the power-off plate 19 towards the outer casing 1, the power-off plate 19 pushes the positive electrode head 17 and the negative electrode head 18 upwards at this time, so that the positive electrode head 17 and the negative electrode head 18 are separated from the positive electrode column 6 and the negative electrode column 7, and power-off is obtained at this time. When power is on, the power-off plate 19 is pulled out. At this time, the positive electrode head 17 and the negative electrode head 18 are pushed down by the elastic forces of the first spring 15 and the second spring 16, so that the positive electrode head 17 and the negative electrode head 18 are respectively in contact with the positive electrode column 6 and the negative electrode column 7, enabling the plug 5 to be powered on.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
