Abstract
An anti-interference lock catch relates to the technical field of lock catches. It includes: the lock catch body is provided with an accommodating groove; the sheet body, the induction piece and the sealing layer are sequentially arranged in the accommodating groove; the sheet body is made of a material having a function of absorbing electromagnetic waves. By adopting the technical scheme, the anti-electromagnetic wave interference sensor has the advantages of anti-electromagnetic wave interference and difficulty in falling of the sensing piece.
Description
Technical Field
The utility model relates to a hasp technical field, concretely relates to anti-interference hasp.
Background
The shared device lock is required to be provided with a sensing piece on the lock catch, and the reading device sends out an information instruction after sensing to execute corresponding action. The existing locking plate is made of metal, and the metal is easy to shield signals, so that the problem that the locking plate cannot be read is often caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide an anti-interference hasp, have anti electromagnetic wave interference advantage.
In order to achieve the above object, the utility model adopts the following technical scheme: a tamper resistant latch comprising: the lock catch body is provided with an accommodating groove; the sheet body, the induction piece and the sealing layer are sequentially arranged in the accommodating groove; the sheet body is made of a material having a function of absorbing electromagnetic waves.
The utility model discloses further set up, the lamellar body is soft electromagnetic wave absorption membrane.
The utility model discloses further set up, the seal coat is for dripping the glue film.
The utility model discloses further set up, be equipped with anti-jamming circuit in the response piece.
After the technical scheme is adopted, the utility model discloses beneficial effect does:
1. in the utility model, the sheet body made of the material with the function of absorbing the electromagnetic wave is arranged to absorb the electromagnetic wave, eliminate the back-and-forth reflection of the electromagnetic wave in the holding tank and reduce the interference of clutter to the induction part; still seal the opening of holding tank through being equipped with the seal coat for the response piece is difficult for droing.
2. The utility model discloses in, through be equipped with anti-jamming circuit in the response piece for the response piece can not disturbed and the maloperation, effectively improves the security of hasp.
