Abstract
The utility model provides a lock tongue connecting structure of a burglary-proof door lock and belongs to the technical field of burglary-proof door locks. The problems of the existing lock tongue which is fixed by a riveting technology that the riveted part easily becomes loose after a specially shaped lock tongue with a non-circular cross section is fixed with a lock tongue fixing plate for a long time, thereby enabling the lock tongue to rotate relative to the lock tongue fixing plate are solved. The lock tongue connecting structure of the burglary-proof door lock is used for connecting the lock tongue with the lock tongue fixing plate and comprises a connector, wherein the connector is arranged at a lock tongue connecting end, the lock tongue is riveted with the lock tongue fixing plate through the connector, locating clamp grooves are also formed in the end surface part of the lock tongue connecting end, bosses are correspondingly arranged on the lock tongue fixing plate, and the bosses are arranged in the corresponding locating clamp grooves in a one-to-one correspondence way. The lock tongue connecting structure of the burglary-proof door lock has the advantages that a peripheral limit function is performed through the clamp connection relationship of the bosses and the locating clamp grooves, the forming and clamp connection assembly process of the bosses is simple and convenient, the lock tongue is firmly clamped, and the stability is great.
Description
Technical field
The utility model belongs to safe-guard door lock technical field, relates to a kind of dead bolt syndeton of safe-guard door lock.
Background technology
At present, in various safe-guard door locks on the market, dead bolt is all arranged on bolt-fixing board, drives it to stretch out lock housing lock or be retracted to realize in lock housing and unblank by bolt-fixing board.Between traditional dead bolt and bolt-fixing board, mostly by riveting process, be fixed together, service time one is of a specified duration, and riveted joint place is easily loosening, causes dead bolt to rotate with respect to bolt-fixing board.
Above-mentioned situation is for columniform dead bolt, and impact is not also large especially, but is non-circular special-shaped dead bolt for dead bolt cross section, after dead bolt rotates, can cause the stuck situation of dead bolt and lock housing panel, and impact is normally used.
For this reason, people improve the syndeton between dead bolt and bolt-fixing board one after another, more effectively between dead bolt and bolt-fixing board, set up circumferential position-limit mechanism, prevent that dead bolt from rotating, but most complex structure, cost of production is higher.
Summary of the invention
The purpose of this utility model is for the existing the problems referred to above of existing safe-guard door lock, and has proposed a kind of dead bolt syndeton of simple in structure, circumferential spacing firm safe-guard door lock.
The purpose of this utility model can realize by following technical proposal: a kind of dead bolt syndeton of safe-guard door lock, for dead bolt is connected with bolt-fixing board, it comprises the connector that is arranged on dead bolt link, dead bolt is riveted by connector and bolt-fixing board, it is characterized in that, the end of described dead bolt link also offers locating groove, and on bolt-fixing board, correspondence is provided with boss, and described boss one by one correspondence is arranged in corresponding locating groove.
The end face of dead bolt link is towards bolt-fixing board, boss and locating groove over against, when dead bolt and bolt-fixing board riveted joint, boss is just fastened in locating groove, and dead bolt is circumferentially played to position-limiting action.
In the dead bolt syndeton of above-mentioned a kind of safe-guard door lock, described boss and bolt-fixing board are integral structure.
In the dead bolt syndeton of above-mentioned a kind of safe-guard door lock, described boss protrudes formation by the extruding bolt-fixing board back side.In dead bolt riveted joint process, can part bolt-fixing board be pressed in locating groove to form above-mentioned boss by modes such as extruding.
In the dead bolt syndeton of above-mentioned a kind of safe-guard door lock, described locating groove arranges around the circumferential interval of connector.
In the dead bolt syndeton of above-mentioned a kind of safe-guard door lock, described dead bolt comprises tongue body and body, tongue body is fixedly installed in the trepanning of body and one end is stretched out and formed above-mentioned connector, and above-mentioned locating groove is opened in body towards the end face of bolt-fixing board one end.Tongue body can coordinate with the body of various shapes, forms various special-shaped dead bolts.
Compared with prior art, the dead bolt syndeton of this safe-guard door lock, by the clamping relation of boss and locating groove, plays circumferential position-limiting action.The formation of boss and clamping assembling process are simple and convenient, and clamping is firm, good stability.
