Description

A kind of crescent lock

Technical field

The utility model relates to door and window accessory field, particularly a kind of crescent lock.

Background technology

At present, the application of crescent lock on door and window is very extensive, its structure is made up of handle, tapered end hook, base and cover etc., wherein, most crescent lock is fixed on base by screw handle, and screw is connected to long use easily occurs getting loose phenomenon, affects result of use and the life-span of crescent lock, also have most crescent lock structures comparatively complicated, assemble loaded down with trivial details.Based on above-mentioned deficiency, so be extremely necessary again develop the structure of crescent lock and design.

Utility model content

The purpose of this utility model is to solve the problem and not enough, provides a kind of crescent lock, and this crescent lock has the advantages such as structure is simply firm, easy to assembly.

The technical solution of the utility model is achieved in that

A kind of crescent lock, comprise handle, tapered end hook, base, cover, its feature is also to comprise cover, spring leaf, location-plate, spring, described handle, at its lower end has made step-like socket part, socket part is provided with card holding trough, on the end face of handle, at its lower end socket part setting, offer embedding slot simultaneously, described base top surface is provided with boss, this boss end face offers the inlaid hole being communicated with base lower surface, die cavity is offered in base lower surface, this die cavity and inlaid hole connect, the socket part of described handle is through tapered end hook, cover is inlaid in the inlaid hole of base, stairstepping socket part in described base is set with cover, spring leaf is provided with outside described cover, and spring leaf is inlaid in die cavity, described location-plate middle card is contained in the card holding trough of the socket part of spring leaf lower end, this location-plate outer rim is on the die cavity chamber wall of base, described spring one end is arranged on cover end face, the other end is inlaid in the embedding slot of handle, described base offers two counter sinks, plastic washer is provided with between the boss end face of described handle and base.

This practical beneficial effect: crescent lock is by handle, tapered end hook, base, cover, cover, spring leaf, location-plate, the formations such as spring, wherein, handle is inlaid on base through tapered end hook and cover, and by location-plate, the handle be inlaid in base is stuck in base, and the spring be arranged between cover and handle can provide an elastic force to make handle capable of being and base keep relative fixing, be unlikely to loosen or come off, as long as spring stands intact, even if also there will not be the phenomenon loosening or come off under using for a long time, moreover spring is stressed less, simultaneously because whole crescent lock structure is comparatively simple, so assemble very convenient.
