Abstract

The utility model provides a rolling door land clock, which comprises a rolling door and a side lock linkage framework. The key of the utility model is that: a lock box which is arranged under the rolling door in pairs and integrated with the land and a lock head which is corresponding to the lock box and arranged at the rolling door angle steel and controlled by the rolling door side lock linkage framework. When use, pull down the rolling door, the upper bolt at the lock head inserts into the lock box, the left and the right bolts in the lock box are separated by the acting of the upper bolt, after the upper bolt is placed in a right place, the left and the right bolts return under the acting of the spring, here, the key is rotated, the upper bolt rotates under the acting of the side lock linkage framework, to realize the simultaneous locking of the side lock and the land lock, in such way, the utility model not only makes the rolling door fixedly integrate with the door frame and the land, but also greatly improves the prize-proof assurance performance of the rolling door.

Description

A kind of rolling door ground lock

One, technical field:

The utility model relates to a kind of and existing rolling screen door lock adapted, thereby rolling door is not only locked with the rolling door ground that ground is solidified as a whole with doorframe, while.

Two, background technology:

Rolling door is pried open and destroyed to two keyed ends about existing rolling door only has, lawless people very easily by instruments such as steel poles from the rolling door bottom, thereby its theftproof performance is relatively poor.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of theftproof performance, and good rolling door ground is locked.

The purpose of this utility model can reach by following technical measures.That is: lock and existing rolling screen door lock adapted to this rolling door, thereby rolling door is not only combined as a whole with ground with doorframe, while, it comprises the link gear of rolling door and limit lock, and its key is: mounted in pairs the lock box that is solidified as a whole below the rolling door and with ground and with the corresponding tapered end that is fixed on the angle steel of rolling door base by bolt and nut, is subjected to the lock link gear control of rolling door limit in lock box position.During use, the roller shutter six of leaving behind, upper lock tongue in the tapered end inserts in the lock box, left and right sides dead bolt in the lock box is divided right and left under the effect of upper lock tongue, after upper lock tongue put in place, left and right sides dead bolt resetted under the restoring force effect of spring, turn this moment key, upper lock tongue rotates under the link gear effect of limit lock, to realize limit lock and the locking simultaneously of ground lock.

The utility model compared with prior art not only makes rolling door and doorframe but also is solidified as a whole with ground, has greatly improved the anti-prying performance of rolling door.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model.

Five, the specific embodiment:

Referring to Fig. 1, the utility model rolling door ground lock, the link gear that comprises rolling door and limit lock, its key is: mounted in pairs is fixed on the rolling door bottom girder angle steel 6 by bolt and nut 5 at the lock box 8 that is solidified as a whole below the rolling door and with ground with lock box 8 positions are corresponding, is subjected to the tapered end 3 of rolling door limit lock link gear control.

Described lock box 8 inner chamber symmetric arrangement spring 10, dead bolt 9, the bottom surface is provided with stone bolt 11.Described tapered end 3 has a lock tube 7, its inner chamber is equipped with upper lock tongue 2, upper lock tongue 2 afterbodys have a dead bolt seat 12 that combines as a whole with it, are provided with one and the joining connecting rod 4 of rolling door limit lock link gear at dead bolt seat 12 end face eccentric positions, and upper lock tongue 2 links by pin 1 and lock tube 7.

Described lock tube 7 waists have a groove, and the position of this groove is corresponding with the position of pin 1 on being fixed on tapered end 2.
