Abstract

The utility model relates to an antitheft door device, which comprises a bottom seat (embedded at the ground level), a door frame and a lock fixed in the doorframe, and is characterized in that a lock catch is installed in the doorframe and can rotate around a rotating shaft; the lock is connected with a deflector rod; a deflector pillar on the deflector rod is connected with the lock catch; a doorframe lock hole is formed on the doorframe in the corresponding position of the lock catch; a bottom seat lock hole is formed on the bottom seat and corresponds to the doorframe lock hole; a lock pillar is arranged in the bottom seat and corresponds to the lock catch; a repair and replacement lock hole is formed on the inner side of the door frame in the corresponding position of the lock. In the utility model, a plurality of lock catches installed in the doorframe is locked with the lock pillar arranged in the bottom seat, and two ends of the deflector rod latch a door bracket so as to have multilevel locking effect and increase the difficulty of lock picking; the repair and replacement lock hole is formed on the inner side of the door frame in the corresponding position of the lock, thereby facilitating the replacement or maintenance of the lock. Therefore, the antitheft door device is installed simply and conveniently, has good antitheft performance, and can be widely applied to places, such as shops, warehouses, etc.

Description

The pick-proof door gear

Technical field

The utility model relates to pick-proof gate technique field, particularly a kind of pick-proof door gear.

Background technology

For door, be not only and be convenient for people to discrepancy, also must have certain barrier propterty, to guarantee the security of the lives and property in the room.Existing part is anti-forces open the door because this body structure exists defective to be pried open easily, as have plenty of and only have dead bolt and the single lock structure of doorframe, the offender can utilize " one " word criticize etc. the sheet tool used in crime pry open in the chien shih dead bolt separate with doorframe, thereby door is opened.

The utility model content:

In order to address the above problem, the purpose of this utility model is for a kind of simple in structure, cheap and security door device that the pick-proof performance is good is provided.

The purpose of this utility model is achieved in that a kind of pick-proof door gear, comprises base (burying plane earth), doorframe and is fixed on lock in the doorframe, is equipped with in the described doorframe by rotating shaft and is fixed on snap close on the doorframe, and snap close can rotate around the axis; Lock is connected with driving lever, has reversed column to be connected with snap close on the driving lever, and reversed column can move in the snap close upper shed; Doorframe has the doorframe lockhole in the snap close relevant position; Have on the base and the corresponding base lockhole of doorframe lockhole; Lock with the snap close correspondence is housed in the base.

Described doorframe inboard and phase-locked answer the position to be equipped with to repair change fore shaft.

The utility model is sealed by a plurality of snap closes that are equipped with in doorframe and the lock that is contained in the base, and driving lever two door bolt plays multiple locking effect in entering, and increases the difficulty of prying open; Doorframe inboard and phase-locked answer the position to be equipped with to repair change fore shaft, be convenient for changing or keep in repair lockset.Therefore, this criminal both simple installations of device of forcing open the door have good pick-proof performance again, can be widely used in places such as shop, warehouse.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

The specific embodiment

The utility model is a kind of pick-proof door gear, comprises base 2, doorframe 1 and is fixed on lock 3 in the doorframe 1, is equipped with in the described doorframe 1 by rotating shaft 51 and is fixed on snap close 5 on the doorframe 1, and snap close 5 can 51 rotate around the shaft; Lock 3 is connected with driving lever 4, has reversed column 41 to be connected with snap close 5 on the driving lever 4, and reversed column 41 can move in snap close 5 upper sheds; Doorframe 1 has doorframe lockhole 7 in snap close 5 relevant positions; Have on the base 2 and doorframe lockhole 7 corresponding base lockholes 8; Lock 6 with snap close 5 correspondences is housed in the base 2.

Described doorframe 1 inboard and lock 3 relevant positions are equipped with to repair and are changed fore shaft 9.

When using the utility model to carry out locking, lock 3 promotes driving lever 4 to moving away from lock 3 directions, and reversed column 41 moves in snap close 5 upper sheds on the drive driving lever 4, makes snap close 5 to lock 6 deflections, thus locking; When opening, lock 3 promotes driving levers 4 to moving near lock 3 directions, drives that reversed column 41 moves in snap close 5 upper sheds on the driving lever 4, makes snap close 5 to away from lock 6 direction deflections, thereby opens.

Described doorframe 1 inboard and lock 3 relevant positions are equipped with to repair and are changed fore shaft 9, in order to carrying out necessary maintenance or replacing to locking 3.

Certainly, above-described embodiment, it is preferred embodiment of the present utility model, be not to limit practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model scope.
