The crescent lock of the shown conventional metals material of Fig. 1, As time goes on, easily there is the problems such as yielding, oxidizable in lock 1, need to change timely, if increase the thickness of lock, can increase again its cost of production.To this, how to realize the not yielding of crescent moon lockset, particularly lock, the while can be avoided complicated manufacturing process again and reduce production costs, the major issue that Zhe Shi lots of manufacturers need to solve.

Summary of the invention

The utility model provides a kind of lock of crescent lock, and its object solves the easily problem of distortion of metal lock, and meanwhile, the five metals lock that utilizes the injection moulding of lock to replace tradition to be stamped to form, effectively reduces production costs.

Therefore, the utility model comprises handle, jam plate and lock, described handle is provided with a rivet, lock is provided with axis hole, rivet is assemblied in this axis hole through jam plate, and described lock is plastic shell, it is characterized in that: in shell body, have an inner chamber, the wall of this inner chamber is respectively sidewall and diapire, and is provided with the reinforcing rib for firm this plastic shell in this inner chamber.

The axis hole of described lock is positioned at the medium position of this lock, and a upper and lower end of this axis hole is provided with the locating hole of installing for screw relatively, and reinforcing rib lays respectively at the surrounding position of this axis hole, two locating holes.

Described reinforcing rib is respectively cross reinforcing, vertical strengthening ribs, wherein, this cross reinforcing is positioned at the sidewall of locating hole dual-side level connection joint lock, and described vertical strengthening ribs longitudinally connects the outer of two locating holes and axis hole, until fix the inner chamber wall of the upper and lower end parts of this lock.

The angle of described sidewall and diapire is provided with corner reinforcing rib.

The beneficial effects of the utility model are: lock is that plastic cement material is made, effectively reduce production costs and avoid problem of oxidation, and in the inner chamber of this lock, be provided with the reinforcing rib that makes this lock firm, solve the easy problem on deformation of lock, be finally made into inexpensive high-quality lock accessory.
