Stainless steel fully enclosed marble lock

Abstract

The invention discloses a stainless steel totally-enclosed spring lock, comprising a lock head, a lock beam, a lock latch and an alarm and the like, wherein the lock beam is treated by quenching; the lock latch is made of thickened type stainless steel square tube with good quality and high strength; an inner container is chained in the whole length of the square tube and is also made of thickened type square tube; and stainless steel cover plates at the two ends are totally enclosed by full welding, so that the performances such as rust prevention, shearing resistance, prying resistance, sawing resistance and smashing resistance of the stainless steel totally-enclosed spring lock are better. A self-locking part adopts combination of a stopping sleeve with a small upper part and a large lower part, a steel ball retainer, steel balls and a spring; when in unlocking, the lock beam is ejected automatically without separating from the lock latch; and a short foot of the lock beam is aligned to a hole position of the lock latch to press downwards and lock automatically. Therefore, the stainless steel totally-enclosed spring lock is flexible and convenient to use.

Description

Technical field

[0001] The invention relates to a lock, in particular to a stainless steel fully enclosed pin lock. Background technique

[0002] Known domestic market at present, the kind of lock is a lot, and what especially bicycle, battery-driven car major part use is U-shaped lock, is commonly called as safe lock, and these locks are generally made of iron more, simple in structure, poor in strength, and anti-theft performance is not good enough. Contents of the invention

[0003] In order to overcome the deficiencies in the anti-theft performance of conventional locks for bicycles and electric vehicles in the existing domestic market, the invention provides an improved stainless steel fully enclosed tumbler lock.

[0004] The technical solution adopted by the present invention to solve the technical problem is: the U-shaped lock beam (1) adopts a high-quality high-strength cold-drawn circle, and the outer circle of the long leg has a clear angle groove and the outer ...

Examples

Embodiment Construction

[0008] In the figure, two holes are drilled on the surface of the stainless steel square tube of the lock bolt (2), the center of which is consistent with the center of the two feet of the lock beam (1). There is a stop sleeve (12) in the hole, a steel ball retainer (16) is arranged in the stop sleeve (12), a steel ball (13) and a second spring (14) are arranged in the steel ball retainer (16), and a lock head is installed on the left end Fasten the connecting rod (17) with the countersunk head screw (18); press the liner (3) into the inner cavity of the latch (2), insert the long leg of the lock beam (1) into the hole at the right end of the latch (2) Circle (4) the first spring (8) outer positioning sleeve (6), right cover plate (7) left cover plate (19), the full welding fully enclosed keyhole position of two ends cover plate is exposed.
