Embodiment 1

[0028] Such as figure 1 As shown, the glass breaker power adjustment device includes a piston cylinder 1, and the piston cylinder 1 is provided with a through hole communicating its inner cavity with the outside world, and also includes a bolt fixing block 3, which is fixedly connected to the piston On the barrel 1 , the bolt fixing block 3 is also provided with an adjusting bolt 5 threadedly connected with the bolt fixing block 3 , and the axial direction of the adjusting bolt 5 is collinear with the axial direction of the through hole.

[0029] Specifically, the set piston cylinder 1 is the energy generating chamber of the explosive glass breaker, that is, the explosive bomb used explodes in the piston cylinder 1 to generate rapidly expanding gas, and the through hole arranged on the piston cylinder 1 is used for the discharge part Gas; and by rotating the adjusting bolt 5 relative to the bolt fixing block 3, the distance between the adjusting bolt 5 and the piston cylinder ...

Embodiment 2

[0032] This embodiment is further improved on the basis of embodiment 1, as figure 1 As shown, the bolt fixing block 3 is in the shape of a groove with one end closed.

[0033] Also includes a cylindrical internal thread sleeve 2, the center of the internal thread sleeve 2 is provided with a central through hole, and the inner wall surface of the central through hole is provided with internal threads, and one end of the internal thread sleeve 2 is fixedly connected to the bolt fixing block 3, and the internal thread sleeve 2 is located between the piston cylinder 1 and the bolt fixing block 3, and the distance between the other end of the internal thread sleeve 2 and the outer wall of the piston cylinder 1 is within the range of 1 mm to 3 mm.

[0034] This arrangement has a simple structure and is easy to process and manufacture. Specifically, after the connection between the bolt fixing block 3 and the piston cylinder 1 is completed, when the explosive glass breaker is in us...

Embodiment 3

[0036] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, it also includes a locking nut 4 , which is threadedly connected with the adjusting bolt 5 , and the locking nut 4 is located between the bolt fixing block 3 and the outer end of the adjusting bolt 5 .

[0037] The threads on the bolt fixing block 3, the locking nut 4 and the adjusting bolt 5 are all fine threads.

[0038] The set lock nut 4 is used to fix the position of the adjustment bolt 5 relative to the bolt fixing block 3 through the lock nut 4 after the adjustment bolt 1 is adjusted to a reasonable position, so as to ensure the stability of the performance of the present invention during use.

[0039] The fine-pitch screw thread has a smaller tooth pitch, and this setting makes the present invention have better power adjustment performance.

Abstract

The invention discloses a glass breaker power adjusting device which comprises a piston cylinder (1). A through hole connected with an inner cavity and the outside is formed in the piston cylinder (1). A bolt fixing block (3) is further included. The bolt fixing block (3) is fixedly connected to the piston cylinder (1). An adjusting bolt (5) in thread connection with the bolt fixing block (3) is arranged on the bolt fixing block (3). The axial direction of the adjusting bolt (5) and the axial direction of the through hole are collinear. Glass breaking efficiency can be effectively improved, unnecessary vibration borne by a user is lowered, and the safety of personnel near glass is protected.

Description

technical field [0001] The invention relates to the technical field of emergency glass breaking devices, in particular to a power regulating device for a glass breaking device. Background technique [0002] In recent years, with the further development of glass manufacturing technology, rigidity tempered glass has been widely used in various vehicles, shopping malls and home decoration. At the same time, glass curtain walls and glass windows also serve as safe passages for people to evacuate in case of emergency. [0003] In the prior art, for glass breakers used in emergency situations, safety hammers, spring-type glass breakers and piston impact glass breakers with stronger crushing capacity have appeared. The piston impact glass breakers include external high-pressure gas Source glass breaker and explosive glass breaker. Compared with the external high-pressure air source glass breaker, the explosive glass breaker is more and more used because of its advantages of porta...
