Description

Anti-theft safety door with anti-prying steel door bolt

Technical Field

The utility model belongs to the technical field of the emergency exit, concretely relates to take theftproof emergency exit of pick-proof steel keeper.

Background

The anti-theft safety door mainly has the function of anti-theft, common doors in the market are usually easy to pry open, and the anti-theft doors can also be pried open, but the difficulty degree is different. At present, some doors are additionally provided with bolts indoors, so that two locks are added, and the bolts can prevent thieves from breaking in. For example, publication No. CN201687306U discloses a box-type anti-picking door bolt, which is composed of a bottom plate, a lock catch and an L-shaped door bolt. The box-type anti-prying door bolt is arranged on the door, so that the problem that a thief intrudes after the door lock is pried is well solved. But L shape keeper needs the pull to remove when locking and unblock, and the keeper can have frictional force with the bottom plate, and it can become more hard to use the back pull after having used for a long time.

Disclosure of Invention

The utility model discloses to the indoor easy quilt of lock among the prior art by the sled is gone into, installs the comparatively hard drawback of keeper pull additional, provides a take anti-theft safety door of pick-proof steel keeper, and this anti-theft safety door is difficult is used comparatively conveniently by sled and keeper.

The invention aims to be realized by the following technical scheme: the utility model provides a take anti-theft safety door of pick-proof steel keeper, including the door frame, with the door plant that the door frame cooperation was used, be equipped with between door plant and the door frame and be used for fixing the lock on the door frame with the door plant, the door plant has the mount pad towards indoor one side fixed mounting, install on the mount pad and only can follow the rotatable horizontal pole in door plant plane, the fixed fixture block that is equipped with of one end that the mount pad was kept away from to the horizontal pole, the fixture block side is outwards outstanding for the horizontal pole, fixed mounting has the seat of tying on the door frame, the side of tying the seat towards the mount pad is equipped with the draw-in groove.

Among the above-mentioned scheme, the horizontal pole passes through the mount pad and rotationally installs on the door plant, and the seat fixed mounting of restricting is on the door frame, and the mounting means is comparatively simple. The mounting seat, the cross rod, the clamping block and the bolt seat form a door bolt, the cross rod is rotated to enable the clamping block to be clamped in the clamping groove on the bolt seat, and the door bolt is locked. When wanting to open the door from outdoor, because the fixture block is by spacing in the draw-in groove, the door plant is connected with the doorframe by the keeper is fixed, can not open, prevents like this that the thief from prying the bad door lock from the outside and just can get into indoorly, has improved the security of theftproof emergency exit. When the door is opened from the indoor, the door bolt can be normally opened only by rotating the cross rod and rotating the clamping block out of the clamping groove of the bolt seat and opening the door bolt, and the cross rod is rotated to be simpler and less laborious than the pulling door bolt.

Preferably, the bolt seat comprises a bottom plate fixed on the door frame, a connecting block is fixedly arranged on one side, back to the door frame, of the bottom plate, the clamping groove comprises a first groove and a second groove which are mutually communicated, the first groove and the second groove are perpendicular to each other in the cross section of the clamping groove and are combined to form a T-shaped structure, the upper end of the clamping groove is communicated with the upper end face of the connecting block, and the second groove in the clamping groove is communicated with the side face, facing the mounting seat, of the connecting block. The bolt seat is fixedly arranged on the door frame through the bottom plate, and the installation mode is simple. The cross section of the clamping groove is of a T-shaped structure, the second groove is communicated with the side face, facing the mounting seat, of the connecting block, and the upper end of the clamping groove is communicated with the upper end face of the connecting block, so that the cross rod and the clamping block can enter the clamping groove from the upper end of the bolt seat.

Preferably, the first groove is communicated with the side surface of the bottom plate facing the door frame. Due to the design, the bolt seat can be integrally formed by metal in a stamping mode, the manufacturing process is simple, and materials are not wasted.

Preferably, the fixture block and the cross bar are perpendicular to each other and combined to form a T-shaped structure. The clamping block and the cross rod form a T-shaped structure which is matched with the T-shaped structure of the clamping groove, and when the door bolt is locked, the door plate cannot rotate or can not move in a pushing and pulling mode to be separated from the door frame.

Preferably, the mounting seat comprises a mounting plate for mounting the cross rod, the upper end and the lower end of the mounting plate respectively face the vertical fixedly connected supporting plate in the door plate direction, the vertical fixedly connected supporting plate is fixedly connected with a fixing plate, and the mounting seat is fixedly mounted on the door plate through the fixing plate. The mounting panel is compared in the outside protrusion of fixed plate, gives the horizontal pole installation headspace on the one hand, and on the other hand, the door plant is scraped to the difficult door plant of wiping when rotating the horizontal pole to distance between increase horizontal pole and the door plant, scrapes the colored door plant.

Preferably, the width of one end of the cross bar close to the fixture block is smaller than that of one end close to the mounting seat. The advantage of doing so is, can suitably widen the horizontal pole in order to improve horizontal pole intensity, under the condition that does not increase the bolt seat, can also guarantee that the fixture block is arranged in the draw-in groove of bolt seat completely when using.

Preferably, the side of the cross bar facing the indoor is provided with a projection for operating the rotation of the cross bar. When the cross rod is rotated, the operation of the cross rod is not required to be directly performed, the bulge can be grasped for operation, and the operation is convenient.

Preferably, the mounting seat is fixedly mounted on the door panel on the side close to the door lock. Therefore, the door bolt is added after the door is locked, so that the door is convenient and handy, and the door is opened in the same way.

Preferably, the door panel is rotatably mounted to the door frame by a hinge. Such a mounting mode is simple and common.

Compared with the prior art, the utility model discloses following beneficial effect has: even if the door lock is prized, a door bolt consisting of an installation seat, a cross bar, a clamping block and a bolt seat can be locked to prevent a thief from entering the door lock, so that the anti-prying and anti-theft effects are achieved; manufacturing process is simple, and the installation is comparatively convenient, and the operation of rotary type is more convenient laborsaving than the pull formula.
