Referring to fig. 1, fig. 1 is a schematic structural diagram of a protection device for preventing a switch 300 from being opened by mistake according to the present invention. Mainly comprises a protective clip 100 and a forbidden card 200, wherein one end of the protective clip 100 is used for holding a switch 300 and protecting the switch 300, and the switch 300 can be a common air switch 300 or other types of switches 300.

As shown in fig. 1 to 3, the protection clip 100 is mainly composed of a first clip body 110 and a second clip body 120, the first clip body 110 and the second clip body 120 are hinged by a hinge 130, and a spring 140 is sleeved on the hinge 130, similar to a common clip, and can be clamped by force, in order to seal the switch 300 to a certain extent and prevent misoperation of others, in the process of clamping the switch 300, only two sides of the switch 300 are protected by a protection device, so that a baffle plate 170 is further provided, as shown in fig. 2, the free end of the baffle plate 170 extends towards the switch 300, thereby playing a certain protection role.

In the process of daily maintenance, the maintenance is carried out through power-off, the maintenance in multiple places can be controlled by one general switch 300, therefore, more personnel can be maintained, in order to inform that other people are in the maintenance state at present, the mistaken closing is prevented, unnecessary accidents are caused, a plurality of forbidden cards 200 are arranged, each maintenance part correspondingly comprises one forbidden card 200, the forbidden card 200 is inserted into the other end of the protection clamp 100, specifically, the embedded grooves 150 are arranged on the first clamp 110 and the second clamp 120, the forbidden cards 200 can be inserted into the insertion grooves, after the forbidden cards 200 are inserted, the whole protection clamp 100 cannot be freely opened in the past, the maintenance state in which other people are in place is informed is achieved, the mistaken closing is carried out, and the safety is improved.

Also in order to improve the security of whole device, further prevent people's maloperation, perhaps the mistake is got and is forbidden tablet 200 and cause dangerous condition such as occurence of failure to take place, the utility model discloses further make the improvement to forbidden tablet 200's structure, specifically set up lock body assembly 210 in forbidden tablet 200, as shown in fig. 4 and 5, this lock body assembly 210 includes locking lever 211 and key 212, wherein the key 212 then is placed in the maintainer hand, and each forbidden tablet 200 all adapts a key 212 for.

As shown in fig. 4, the locking rod 211 mainly includes a locking post 2111, a fixing post 2112 and a sliding post 2113 are sleeved on the locking post 2111, an elastic member 2114 is disposed between the fixing post 2112 and the sliding post 2113, and a pushing block 213 is mounted on the sliding post 2113, the sliding post 2113 can extend into the insertion slot 150 and extend into the fixing slot 160, the pushing block 213 is preferably cylindrical, a plurality of locking rods 211 may be disposed in each lock body assembly 210, in this embodiment, there are 3 locking rods 211, two of the locking rods are mounted in the same direction, and the other locking rod is mounted in the opposite direction, specifically, whether the fixing posts 2112 on two adjacent locking rods 211 are mounted on the same side.

The key 212 is provided with an abutting block 214 capable of abutting against the pushing block 213, and the sliding column 2113 is driven to move correspondingly by the abutting block 214 through inserting the key 212. Specifically, after the key 212 is inserted into the slot 215, the sliding post 2113 extending out of the holding plate 200 is retracted into the holding plate 200, so that there is no fitting relationship between the holding plate 200 and the first clip body 110 or the second clip body 120, and the holding plate 200 can smoothly slide out of the insertion slot 150.

The specific use method of the device comprises the following steps:

when the card holder needs to be overhauled, power is cut off, one end of the protection clamp 100 clamps two sides of the switch 300 at the moment, the forbidden cards 200 in the protection clamp 100 are inserted into the embedded groove 150 at the other end of the protection clamp 100, after the forbidden cards are inserted, the sliding columns 2113 on the locking rods 211 extend towards the direction of the fixing grooves 160 under the action of the elastic pieces 2114, and therefore the purpose of fixing the forbidden cards 200 and the protection clamp 100 is achieved, the forbidden cards 200 cannot be opened randomly due to the insertion of the forbidden cards 200, the protection switch 300 cannot be switched on randomly, and the forbidden cards 200 cannot be taken out randomly by other people in the process that the sliding columns 2113 extend into the fixing grooves 160, and safety is improved.

After the maintenance is completed, the key 212 is inserted from the direction of the locking notch 215 and gradually approaches the lock body assembly 210, and finally the abutting block 214 on the key 212 contacts with the pushing block 213 on the sliding post 2113, so that the pushing block pushes the sliding post 2113 to be retracted into the forbidden cards 200, the forbidden cards 200 are unlocked from the protection clip 100, and the forbidden cards 200 can slide out of the embedded groove 150.

This device is for being used for preventing to open switch 300's protector by mistake, mainly be that the protection presss from both sides 100 and forbids board 200, press from both sides 100 through the protection and make its centre gripping switch 300, thereby make certain obstacle for closed switch 300, the other end that presss from both sides 100 at the protection sets up forbids board 200, through forbidding inserting of board 200, inform other this moment in maintenance state, avoid causing the unnecessary occurence of failure because of the information asymmetry, the device simple structure, design benefit, can fine utilization space, the improvement protection, the effect of informing, thereby improve the security of whole maintenance work.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
