Description

Technical Field

[0001] This utility model relates to the field of electrical automation technology, and in particular to an electrical automation protection device. Background Technology

[0002] During the operation of industrial electrical automation equipment, materials may splash, posing a safety threat to surrounding workers. Therefore, it is necessary to install protective devices around industrial electrical automation equipment to prevent material splashes from harming workers during production and processing.

[0003] For example, Chinese utility model patent CN202221796617.5 describes an industrial electrical automation protection device. By rotating a handle, the handle drives a threaded screw to rotate, which in turn moves two extension plates away from each other, displacing the extension plates from the main board. This adjusts the protection area of ​​the device, improving its applicability. Multiple protection devices can be spliced ​​together to surround electrical automation equipment, meeting protection needs. However, after adjustment, the two extension plates are not locked. When workers collide with the extension plates, they are pushed back into the main board, thus affecting the adjustment effect of the protection area. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical automation protection device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] An electrical automation protection device includes a protection assembly. The protection assembly includes: an extension plate symmetrically arranged inside a main board; a protection plate disposed on one side of the main board and the extension plate; a locking assembly disposed inside the main board and extending through the top of the main board, the locking assembly including: a rotating rod extending through the top of the main board and rotatably connected to the main board; a bidirectional threaded rod disposed inside the main board; a bevel gear disposed between the rotating rod and the bevel gear, such that the rotating rod and the bidirectional threaded rod are meshed; a moving plate symmetrically located outside the bidirectional threaded rod and at the top of the extension plate; a thread disposed outside the rotating rod, a threaded sleeve disposed on the thread and located at the top of the main board; a spring symmetrically located on the inner wall of the main board; a positioning block disposed at one end of the spring, and a positioning groove cooperating with the positioning block disposed on the extension plate.

[0007] Optionally, the bottom of the threaded sleeve is provided with a compression plate and is sleeved on the outside of the thread.

[0008] Optionally, an anti-slip pad is provided between the extrusion plate and the top of the main plate.

[0009] Optionally, a connecting rod is provided on one side of the positioning block and extends through one side of the motherboard, and a pull rod is provided between the connecting rods.

[0010] Optionally, the two ends of the bidirectional threaded rod are provided with positioning rings that cooperate with the extension plate.

[0011] Optionally, the bottom of the extension plate is provided with a pulley, and the inner bottom of the main plate is provided with a slide rail that cooperates with the pulley.

[0012] Optionally, the protective plate includes: a first spring symmetrical to one side of the main plate and the extension plate; and a rubber pad disposed at one end of the first spring.

[0013] Optionally, a support rod is provided on one side of the main board and the extension plate, and extends through the rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Once the extension plate extends to the predetermined position, the compressed spring pushes the positioning block into the positioning groove to lock the extension plate. At the same time, the threaded sleeve rotates, and the rotating threaded sleeve moves downward through the threads, squeezing the top of the main plate, thereby squeezing and locking the bidirectional threaded rod. This achieves bidirectional locking of the extension plate and the bidirectional threaded rod, increasing the stability of the extension plate after extension adjustment and ensuring the protective effect after the extension plate is extended.

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Given that in the current technology, the two extension plates cannot be locked after adjustment, when a worker bumps into the extension plates, the two extension plates will be pushed back into the main board, thus affecting the adjustment effect of the protective area of ​​the protective device.

[0025] like Figure 1-3 As shown, this utility model embodiment provides an electrical automation protection device, including a protection component 1. The protection component 1 includes: an extension plate 12 symmetrically arranged inside a main board 11; a protection plate 13 disposed on one side of the main board 11 and the extension plate 12; a locking component 2 disposed inside the main board 11 and extending through the top of the main board 11, the locking component 2 including: a rotating rod 21 extending through the top of the main board 11 and rotatably connected to the main board 11; a bidirectional threaded rod 23 disposed inside the main board 11; a bevel gear 22 disposed between the rotating rod 21 and the bevel gear 22, so that the rotating rod 21 and the bidirectional threaded rod 23 are meshed; a moving plate 231 symmetrically arranged outside the bidirectional threaded rod 23 and located at the top of the extension plate 12; a thread 24 disposed outside the rotating rod 21, a threaded sleeve 241 disposed on the thread 24 and located at the top of the main board 11; a spring 26 symmetrically arranged on the inner sidewall of the main board 11; a positioning block 25 disposed at one end of the spring 26, and a positioning groove 251 that cooperates with the positioning block 25 disposed on the extension plate 12.

[0026] In use, rotating the rotating rod 21 causes the bidirectional threaded rod 23 to rotate via the bevel gear 22. The rotating bidirectional threaded rod 23 pushes the extension plate 12 out of the main plate 11 via the moving plate 231. When the extension plate 12 extends to the predetermined position, the compressed spring 26 pushes the positioning block 25 into the positioning groove 251 to lock the extension plate 12. At the same time, rotating the threaded sleeve 241 causes the threaded sleeve 241 to move downward via the thread 24, pressing the top of the main plate 11 to press and lock the bidirectional threaded rod 23. This achieves bidirectional locking of the extension plate 12 and the bidirectional threaded rod 23, increasing the stability of the extension plate 12 after extension adjustment and ensuring the protective effect of the extension plate 12 after extension. When the electrical automation equipment is working, the waste generated will be blocked by the protective plate 13, thus protecting the workers.

[0027] Specifically, multiple protective devices are spliced ​​together to enclose the electrical automation equipment and fixed to the ground with bolts to meet the protection requirements.

[0028] Specifically, the bidirectional threaded rod 23 and the movable plate 231 are connected by threads.

[0029] Furthermore, a pressing plate 27 is provided at the bottom of the threaded sleeve 241 and is sleeved on the outside of the thread 24, which increases the area of ​​the threaded sleeve 241 pressing the top of the main plate 11 and improves the stability of pressing and locking the bidirectional threaded rod 23.

[0030] Furthermore, an anti-slip pad 271 is provided between the extrusion plate 27 and the top of the main board 11 to increase the anti-slip properties of the extrusion plate 27 pressing the top of the main board 11.

[0031] Furthermore, a connecting rod 28 is provided on one side of the positioning block 25 and extends through one side of the main board 11. A pull rod 281 is provided between the connecting rods 28. By pulling the pull rod 281, the positioning block 25 is disengaged from the positioning groove 251 and unlocked.

[0032] Furthermore, the two ends of the bidirectional threaded rod 23 are provided with positioning rings 232 that cooperate with the extension plate 12 to position the movement of the extension plate 12 and prevent the extension plate 12 from extending too quickly, which would cause the positioning block 25 to fail to be inserted into the positioning groove 251.

[0033] Furthermore, the bottom of the extension plate 12 is provided with a pulley 29, and the inner bottom of the main board 11 is provided with a slide rail 291 that cooperates with the pulley 29, so that the extension plate 12 and the main board 11 are slidably connected, which increases the stability of the extension plate 12 extending out of the main board 11.

[0034] Furthermore, the protective plate 13 includes: a first spring 131 symmetrical to one side of the main plate 11 and the extension plate 12; and a rubber pad 132 disposed at one end of the first spring 131, which buffers and protects the splashed debris through the first spring 131 and the rubber pad 132.

[0035] Furthermore, a support rod 14 is provided on one side of the main board 11 and the extension plate 12, and passes through the rubber pad 132 to support the rubber pad 132, reduce the load on the first spring 131, and prevent the first spring 131 from bending.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
