Abstract

The invention relates to an adsorption type plunger latch which comprises a pair of adsorption bases, a negative pressure generation device, a pressure adjusting device, lugs with holes and lock bars,wherein adsorption grooves are formed in the lower end surfaces of the adsorption bases, connecting holes are formed in the upper ends of the adsorption grooves, negative pressure suction holes are also formed in one sides of the adsorption bases, and rotating holes are formed in one sides of the negative pressure suction holes; the negative pressure generation device comprises a piston rod, a screw, an annular plug and a tightening nut, and a rack is formed in the side, close to the rotating holes, of the piston rod; the pressure adjusting device comprises a gear, a transmission shaft and ahandheld disc; and the lock bars are inserted into the pair of lugs with holes. According to the adsorption type plunger latch provided by the invention, the pair of adsorption bases is adsorbed to two parts needed to be locked, separately, and is then fixed by means of the lock bars. The plunger latch also can adjust the adsorption force and the sealing extent between the annular plug and the negative pressure suction holes.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to an adsorption type latch. Background technique [0002] Locks are widely used in homes and offices. In recent years, with the rapid development of electronic technology, the traditional lock production has undergone earth-shaking changes. The combination of modern electronic technology and mechanical technology has produced a large number of products such as voice-activated locks and magnetic locks. Advanced electronic locks such as controlled locks, combination locks, remote control locks, and fingerprint locks. [0003] However, for some specific occasions, traditional latches are difficult to adapt to, such as parts that need to be disassembled frequently. If the fixing bolts of traditional latches are used for connection, it is easy to be damaged by the fixing parts during repeated disassembly and assembly. Contents of the invention [0004] In order to solve the technical p...
