Abstract

The utility model provides a novel rotating tensioning lock, and relates to the improvement of the rotating tensioning lock (elastic cam lock) applicable to railway vehicles and the like. The novel rotating tensioning lock comprises a lock body (1), and further comprises a waterproof and dustproof cap (2) and an O-shaped ring (3), wherein the waterproof and dustproof cap (2) is spirally connected to the external wall of one end of the lock body (1); and the O-shaped ring (3) is arranged at the part where a through hole at the front end of the waterproof and dustproof cap (2) is connected with the lock body (1). A step-shaped through hole is arranged at the centre of the front end of the waterproof and dustproof cap (2); and internal threads are arranged on the internal wall of the rear side of the waterproof and dustproof cap (2). According to the novel rotating tensioning lock, the waterproof and dustproof cover and the O-shaped ring are added between a lock head and a lock core of the existing rotating tensioning lock, thus the dustproof and waterproof effects can be achieved, and the service life of the lock body is prolonged.

Description

Novel rotation Strain lock
Technical field:
The utility model relates to the improvement of the rotation Strain lock (elastic force turning-bolt lock) that is used in rolling stock etc., is specifically related to a kind of novel rotation Strain lock with functions of waterproof and dustproof.
Background technology:
The elastic force turning-bolt lock also claims to rotate Strain lock, and it is of many uses, but when being used in places such as rolling stock; Owing between the tapered end of elastic force turning-bolt lock and the lock core certain clearance is arranged; So use the phenomenon that is prone to produce corrosion after a period of time, cause between tapered end and the lock core movable badly, influence is used.
The utility model content:
The purpose of the utility model provides a kind of novel rotation Strain lock, and it has increased dustproof and waterproof cap and O type circle between the tapered end of original rotation Strain lock and lock core, have the effect of dustproof and waterproof, prolongs the application life of lock body.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises lock body 1; It also comprises water proof and dust proof cap 2 and O type circle 3, and lock body 1 one end outer walls are connected with water proof and dust proof cap 2, and the junction of water proof and dust proof cap 2 front end through holes and lock body 1 is provided with O type circle 3.
Described water proof and dust proof cap 2 front end centers are provided with stepped through hole, and water proof and dust proof cap 2 rear side inwalls are provided with internal thread.
The utility model has increased dustproof and waterproof cap and O type circle between the tapered end of original rotation Strain lock and lock core, have the effect of dustproof and waterproof, prolongs the application life of lock body.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the structural representation of water proof and dust proof cap in the utility model,
Fig. 3 is the sectional view of Fig. 2.
The specific embodiment:
