Description

Safety device for door

The utility model is a kind of safety device, is applicable to the inside and outside door of opening.

Present family expenses door is much still locked with a lock or two locks, most doors of still inwardly opening, and its pick-proof, anti-anti-poor ability, the fastness of door is poor, does not have the safety precaution effect.Though the user installation that has at present anti-forcing open the door, it belongs to the many places locking method, the difficulty of increased sled, dialling, but still can not prevent from the problem of " technology unlocking " to still have trouble and worry after " working clan " leaves home." door anti-picking device " (application number 94228633.2) of the applicant invention can effectively improve the safety factor of door, but its only suitable inward.

Task of the present utility model provides a kind of door safety device, reaches the safe and reliable purpose of door.

The purpose of this utility model is achieved in that it comprises a built-in lock and a combination lock that is contained on the door beam that is contained in reveal, it is characterized in that it has an iron pipe thick stick, the right(left)end of iron pipe thick stick is connected on the doorframe of the right side (left side) with swivel joint, the iron pipe thick stick links to each other with the rotation active section, the movable block that matches with combination lock is equipped with at iron pipe thick stick middle part, with the coaxial place of the keyhole of built-in lock gear is being housed, it is meshed with tooth bar on being fixed on the iron pipe thick stick, on a left side (right side) doorframe or wall the hole of creeping into the iron pipe thick stick is arranged.

Said combination lock is same as application number 94228633.2, and promptly it has a fixed muffle and three quills, and each fixes a chuck on each sleeve, and ten positions can be arranged.

Also have elongated slot on the iron pipe thick stick, the rotation active section is hinged with pin by two of male and females, and its afterbody stretches in the iron pipe thick stick, and stop screw is housed.

When locking a door, when promoting dead bolt with key, gear rotates simultaneously and drives the iron pipe thick stick and push ahead the termination of iron pipe thick stick and enter in the side frame hole of a left side (right side).At this moment, combination lock is twisted disorderly, and instant built-in lock is opened, and the iron pipe thick stick still moves back to return, and door can not be opened.Increased safety factor, when opening the door, earlier with combination lock to good, with key dead bolt and iron pipe thick stick are return simultaneously again because combination lock is to good, when the iron pipe thick stick retreated, block can fall into the opening of combination lock, thereby door can be opened.

The utility model has the advantages that: because it uses built-in lock and combination lock simultaneously, safety factor improves, because the iron pipe thick stick is arranged, has increased pick-proof, anti-anti-ability, and iron pipe thick stick and built-in lock, combination lock cooperate, and make door safe and reliable; And the utility model inwardly is fit to, to the various doors of external-open, comprise on anti-the forcing open the door and all can install.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

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

Fig. 2 is the utility model rack structure schematic diagram.

Fig. 3 is the utility model swivel joint and spring structure schematic diagram.

Fig. 4 is the combination lock structural representation.

With reference to the accompanying drawings, the utility model comprises built-in lock 11, combination lock 6, telescopic combination lock 6 has a fixed muffle 17 and three quills 18, and each fixes a chuck 7 jaggy each quill, and its structure is same as " combination lock " in " door anti-picking device ".Main points are: it also has an iron pipe thick stick 5, the right(left)end of iron pipe thick stick 5 is connected on the swivel joint mother 2, swivel joint mother 2 structure is same as " swivel joint " in " door anti-picking device ", promptly be hinged with pin 10 by female 2 two of movable joint public affairs 1, movable joint, swivel joint mother 2 afterbody stretches in the iron pipe thick stick 5, stop screw 4 is arranged on the bar of its afterbody, movable in its elongated slot on iron pipe thick stick 5.Swivel joint mother 2 afterbody has also been adorned spring 3, and it is between the head of iron pipe thick stick 5 and swivel joint 2.Movable block 8 also is housed on the iron pipe thick stick 5, and its grab level is stretched to the chuck 7 of combination lock.The left side of iron pipe thick stick 5 (right side) side-lower has been screwed a tooth bar 10, and it is meshed with gear 9 on being installed in built-in lock 11.The left side of iron pipe thick stick 5 (right side) end stretches in the lateral opening hole of side door, a left side (right side).Be equipped with at doorframe and bump pearl switch 12, reveal is equipped with collision block 16, is connected with the circuit that corresponding alarm bell 14, warning lamp 15 and power supply 13 constitute with bumping pearl switch 12, and this circuit is same as " warning circuit " in " door anti-picking device ".

The utility model proves that through sampling test its cost is low, installs easily, is adapted at inside and outside opening the door and upward uses, and also can install on as anti-forcing open the door, and the increase safety factor improves pick-proof, prevents anti-ability.
