Abstract

The utility model discloses a fireproof door lock with an antitheft structure. In the structure of the fireproof door lock, an antitheft latch is arranged in suspension on a lock bracket; a clip spring rod is arranged in suspension at the left side of the antitheft latch; a compressed spring is fixedly connected under the clip spring rod which is pushed to a higher point by the compressed spring; the clip spring bestrides under the slide way of the antitheft latch and extends to and under a L-shaped clip board transverse plate which is pressed and pushed by the clip spring rod. When the door is closed, the antitheft latch is retracted into the lock bracket by the push of the clip board and the clip spring rod descends to a lower point by means of the slide way position difference of the antitheft latch, thereby the L-shaped clip board is pushed by the spring inside and the clip spring rod is forced to descend to the lower point, furthermore the front end of the L-shaped clip board is forced to be protruded out of the latch 1 and be clipped on the step bracket, so that the latch is ensured no to be retracted into the lock bracket, the function of locking the latch is realized and a prying thief can be prevented from unlocking and coming into the house. The utility model has both practicability and safety.

Description

Fireproofing door lock with theft-prevention structure

Technical field

This practicality relates to a kind of lockset, specifically, relates to a kind of fireproofing door lock with theft-prevention structure.

Background technology

As shown in Figure 1, traditional fireproofing door lock A utilizes a bolt B to fix to come in clamp C to reach the function of closing door lock, yet, when the key thief from using the firm tablet of an elasticity outdoors, cut from top to bottom through crack between a door and its frame and just bolt B can be pushed in the conventional fire door lock A, thereby can easily the door lock unlatching be entered into the room, as shown in Figure 2, and then, the property thief that is stolen is stolen, suffer heavy losses, and this within doors personnel also subject to the burglar or the ruffian injures its life, real in lacking practicality and safety.

From the above, the conventional fire door lockset has following deficiency:

1. fireproofing door lock subjects to burglar's unlatching.

2. the property thief that is stolen is stolen, suffer heavy losses.

3. personnel subject to burglar or ruffian and injure its life peace within doors.

4. do not have practicality.

5. do not have safety.

Therefore, how above-mentioned deficiency being improved is the technological difficulties place that the utility model institute desire solves.

For this reason, the creator in the utility model relies on professional attainment and the technical concept that itself possessed and itself is engaged in the experience of relevant industries, through test of many times and improvement, draws the fireproofing door lock that has theft-prevention structure in the utility model eventually.

Summary of the invention

The fireproofing door lock that has theft-prevention structure in the utility model mainly is in order to solve that existing fireproofing door lock does not possess anti-theft feature and the various problems that causes.

The fireproofing door lock that has theft-prevention structure in the utility model mainly is to be hung with an Anti-theft door bolt on lock, be hung with a jump ring bar in the left side of this Anti-theft door bolt, below this jump ring bar, be connected with a compression spring, by means of the paramount site of jump ring bar, top on the compression spring, this jump ring bar is across under the slide rail of Anti-theft door bolt, and extend across below to L shaped clamp transverse slat, utilize the jump ring bar to compress L shaped clamp transverse slat, when door is shut, Anti-theft door bolt utilizes pushing of clamp and in the retraction lock, and this jump ring bar drops to low points by means of the slide rail potential difference of Anti-theft door bolt, thereby L shaped clamp transverse slat is released by means of the spring in it and is made the jump ring bar drop to low points, and the front end that further makes L shaped clamp protrudes from outside the bolt 1, and fix on the ladder seat, thereby make bolt can't the retraction lock in, reach the function of locking bolt, and can prevent that the key thief from unblanking to enter, and has practicality and safety.
