Abstract

The utility model relates to an anti-theft apparatus for elevator which is composed of a lug, a detention mechanism, a motor and a transmission mechanism. The lug is arranged on the door of the elevator. The detention mechanism comprises a guide track and the outer wall which is fixed on the cage of the elevator. The blocking component which is sliding arranged in the guide track can be moved from top to bottom along the guide track. The blocking component is extended with a horizontal bar. The detention member is pivoted on the horizontal bar by a pin. The transmission mechanism comprises a gear which is arranged on the rotary shaft of the motor. The rack is fixed on the blocking component and is engaged with the gear. The switch is started and the motor is rotated to make the thief-catching device descend. The lug on the door of the cage is clamped to leave a gap on the door of the cage and avoid the robber from choking in the elevator.

Description

The Anti-theft for elevator device

The utility model relates to a kind of robber's of catching device, refers to a kind of proper width of opening by the control elevator door especially, the ruffian is stranded in cage and can not suffocates, so that the Anti-theft for elevator device that the circular public security officer comes to arrest.

High building stands in great numbers at present, in every building, all install elevator, this provides convenience for the personnel that live, are operated in the building, but the people in the turnover building not only much but also very assorted, often form the dead angle of public security, the incident of steal, committing theft happens occasionally, and, do after the case in case the ruffian does violence, often take elevator immediately and escape, and under the situation that the ruffian holds lethal weapons, the ruffian's the best way of surrounding and seize, be the power-off of notice operating personal, the ruffian is stranded in elevator, handle in order to circulating a notice of the public security officer immediately with elevator.In case above-mentioned situation occurs, power supply in the disconnected immediately power down ladder, exhaust equipment stops immediately in the elevator, thereby make cage the inside air can't with extraneous convection current, waiting for that this section that the public security officer comes to handle is inside vexed with the ruffian in the period,, the ruffian is suffocated if the time is of a specified duration excessively, like this, make the public security officer cause inconvenience aspect the ruffian is handled.

The purpose of this utility model provides a kind of Anti-theft for elevator device, when the ruffian is trapped in the elevator after committing theft in the building, can make elevator door only stay the slit of one ventilation usefulness, be beneficial in the elevator and extraneous ventilation, detain the robber in elevator and it is suffocated.

For this reason, the utility model is taked following technical scheme:

A kind of Anti-theft for elevator device is characterized in that it is made up of primary members such as projection 11, detention mechanism 12, motor 15, transmission devices 16, and above-mentioned projection is located on the elevator door B; Above-mentioned detention mechanism 12 is located on the elevator A, and this detention mechanism comprises: guide rails 19, be fixed in the outer wall of cage C; Block resistance member 13 is slidedly arranged in the guide rails 19, can slide up and down along guide rails, and this block resistance member 13 extends a cross bar 20; Detention member 14 is hubbed on the above-mentioned cross bar 20 by trunnion 21, only can swing in less than 90 ° scope; Above-mentioned motor 15 is fixedly arranged on outside the cage C; Above-mentioned transmission device is located between motor and the block resistance member, and this transmission device 16 comprises: gear 17 is arranged in the rotating shaft 22 of motor 15; Tooth bar 18 is fixed on the block resistance member 13, and meshes with gear 17.

By motor 15 drive detention mechanisms 14 to projection 11 near and get this projection 11 so that elevator door B detention in the position of only opening one slit D, be beneficial to cage C and extraneous ventilation and it suffocated.

The utility model not only can be with the ruffian because of in elevator, waits for that the public security officer comes to handle, and can allow again keep good fresh air in the elevator, avoids allowing the ruffian suffocate.

The utility model embodiment is described with reference to the accompanying drawings as follows:

Fig. 1 is that the utility model that is installed on the elevator is implemented illustration.

Fig. 2 is a 2-2 section-drawing shown in Figure 1.

Fig. 3 is a 3-3 section-drawing shown in Figure 1.

Block resistance member 13 extends a cross bar 20 to the right, and detention member 14 is the strip body, and the one ora terminalis is arcuation, have a through hole near this end, for inserting trunnion 21, this end is hubbed at cross bar 20 places by trunnion 21, only swings in less than 90 ° scope limitedly.

Detention member 14 only can rotate and can't rotate away from the direction of block resistance member 13 to block resistance member 13 directions, is beneficial to projection 11 and is slipped between block resistance member 13 and the detention member 14 by detention member 14.Motor power is controlled by administrative center.

After the ruffian robs crime, but injured party's depress switch makes the Warning light of administrative center bright and make the big sound of siren horn, so as to the notice operating personal, and the elevator that operating personal can find the ruffian immediately to be taken, after the switch of the Anti-theft for elevator device 10 of its A that takes a lift pressed, this Switching Power Supply then can starter motor 15 rotations, motor 15 just can transmission transmission device 16, detention mechanism 12 is descended and projection 11 can be got by detention member 14 and the tong-like structure that block resistance member 13 is constituted.In other words, detention member 14 and block resistance member 13 constitute the structure of tong-likes.When two fan elevator door B opened toward both sides respectively, the projection 11 of left side elevator door B top was just pushed detention member 14 left open and is slipped in the tong-like structure that detention member 14 and block resistance member 13 constituted.Can't be because detention member 14 when contacting the upper limb E of elevator door B, is just blocked by this upper limb E again to anticlockwise motion.Therefore, projection 11 just is clamped in the tong-like structure that is made of detention member 14 and block resistance member 13, makes elevator door B can only open slit D one, allow cage C inside and outside air circulate, and the ruffian detained in elevator, again the power supply of elevator is turned off, avoid elevator door impaired.

If just in case during detention of the present utility model mechanism 12 et out of orders, the utility model also can be turned off power supply earlier, secondly the door lock of elevator of floor is opened, with hand the detention mechanism 12 on the cage C up being removed can be from the state of outer releasing detention again.
