[0024] 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.

[0025] Please see Figure 1-7 As shown, an industrial automatic control instrument signal controller includes a controller body 4 and a connecting plate 1 for supporting the controller body 4. The controller body 4 is detachably connected to the top of the connecting plate 1. Horizontal plates 2 are fixedly connected to both sides of the top of the connecting plate 1. A fixing frame 7 is fixedly connected to the top of the horizontal plates 2. A first sliding groove 11 is formed on the surface of the fixing frame 7. A lead screw 8 is movably connected to the inner wall of the first sliding groove 11. A pull plate 9 is fixedly connected to one end of the lead screw 8. A handle is rotatably connected to the surface of the pull plate 9. During use, the operator can rotate the handle and pull the pull plate 9. Both sides of the surface of the pull plate 9 are fixedly connected to... The card plate 10 and the fixing frame 7 have limit grooves 12 on their surfaces. The surface of the card plate 10 is in contact with the inner wall of the limit groove 12. The surface of the lead screw 8 is slidably fitted with an auxiliary plate 14. The surface of the auxiliary plate 14 is in contact with the surface of the fixing frame 7. The surface of the auxiliary plate 14 is provided with a reset mechanism 15. The surface of the fixing frame 7 has a through groove 17. The inside of the through groove 17 is provided with a guide mechanism 18. The surfaces of both sides of the controller body 4 are fixedly connected with extension plates 5. The surface of the extension plates 5 has a second sliding groove and a first card groove 6. The surface of the card plate 10 is in contact with the inner wall of the first card groove 6. The surface of the lead screw 8 is in contact with the inner wall of the second sliding groove.

[0026] The surface of the fixing frame 7 is provided with a slot, the surface of the extension plate 5 is in contact with the inner wall of the slot, and the upper and lower sides of the inner wall of the slot are provided with second slots 13. The surface of the clamping plate 10 is in contact with the inner wall of the second slots 13. This can increase the stability of the position of the extension plate 5 and increase the stability of the clamping plate 10 when limiting the extension plate 5.

[0027] Both sides of the top of the horizontal plate 2 are hinged with protective frames 3. When in use, the protective frames 3 can cover and protect the fixing frame 7 to increase the stability of the controller body 4 after installation. The height of the top of the protective frame 3 is equal to the height of the top of the controller body 4.

[0028] The reset mechanism 15 includes a compression spring 151, a movable plate 152, and a threaded collar 153. The movable plate 152 is detachably connected to the surface of the lead screw 8. The compression spring 151 is sleeved on the surface of the lead screw 8. The threaded collar 153 is rotatably connected to the surface of the movable plate 152. The two ends of the compression spring 151 are in contact with the surfaces of the auxiliary plate 14 and the movable plate 152, respectively. The threaded collar 153 is threaded onto the surface of the lead screw 8. After the operator sleeves the compression spring 151 onto the surface of the lead screw 8, the movable plate 152 can be reset. The threaded collar 153 is fitted onto the surface of the lead screw 8 and rotated to adjust the position of the moving plate 152. At this time, the moving plate 152 cooperates with the auxiliary plate 14 to restrict the position of the compression spring 151 for subsequent use. When the operator pulls the lead screw 8 through the pull plate 9, the threaded collar 153 moves with the lead screw 8 and drives the moving plate 152 to move. The compression spring 151 is compressed by force. Then, under the elastic force of the compression spring 151, the moving plate 152 is forced to move the threaded collar 153 to reset the lead screw 8.

[0029] A light rod 16 is fixedly connected to the surface of the auxiliary plate 14. The light rod 16 slides through the moving plate 152. The stability of the moving plate 152 during movement can be increased by setting the light rod 16.

[0030] The guiding mechanism 18 includes a sleeve 181, a guide plate 182, and a rectangular plate 183. The sleeve 181 is slidably sleeved on the surface of the lead screw 8. The guide plate 182 is fixedly connected to the surface of the sleeve 181. The rectangular plate 183 is fixedly connected to the surface of the guide plate 182. The surfaces of the guide plate 182 and the rectangular plate 183 are slidably connected to the inner wall of the through groove 17 and the surface of the fixing frame 7, respectively. When the lead screw 8 moves, the sleeve 181 can support and guide the lead screw 8. When the operator adjusts the height of the lead screw 8, the guide plate 182 and the rectangular plate 183 cooperate to guide and limit the position of the sleeve 181, thereby increasing the stability of the lead screw 8 when it moves.

[0031] Working principle: The operator installs the connecting plate 1 on the industrial automatic control instrument. When the controller body 4 needs to be disassembled and repaired, the operator can rotate the protective frame 3 and pull the pull plate 9. At this time, the clamping plate 10 and the lead screw 8 move with the pull plate 9, and the contact between the clamping plate 10 and the first clamping slot 6 and the second clamping slot 13 is released. The compression spring 151 is shortened by force. After the limit on the extension plate 5 is released, the operator can lift the controller body 4 and remove the controller body 4. At this time, the controller body 4 can be stably placed on the table for repair. While pulling the pull plate 9, the operator can also press the pull plate 9 down. At this time, the lead screw 8 can drive the guide mechanism 18 to descend. Then, under the action of the elastic force of the compression spring 151, the clamping plate 10 and the lower... The second slot 13 can be used for initial positioning. Finally, the operator places the controller body 4 on the connecting plate 1 and the extension plate 5 inside the slot. The position of the controller body 4 is initially restricted. Then, the operator pulls the pull plate 9 to move the lead screw 8, and the controller body 4 can be lowered. Then, the operator raises the pull plate 9, and the locking plate 10 moves accordingly. Then, under the action of the compression spring 151, the locking plate 10 can pass through the first slot 6 and the upper second slot 13, thereby reinforcing the position of the extension plate 5 and increasing the stability of the controller body 4. The operator flips the protective frame 3 to cover the fixing frame 7 through the protective frame 3, thereby reinforcing the stability of the controller body 4 after installation.

[0032] In addition, after prolonged use, the operator can rotate the threaded collar 153 to remove the moving plate 152, thereby replacing worn parts, so that the lead screw 8 and the threaded collar 153 can work together and the effect of the compression spring 151 can be improved.
