Abstract
The utility model relates to a usually closed dispersed door releaser, which relates to a device for opening and closing a door and is composed of a releaser body arranged on a door frame and a locking hook correspondingly arranged on a door leaf. The releaser body is provided with a casing body and the casing body is provided with an electromagnetic valve and a trigger mechanism controlled by the electromagnetic valve. The front end of the stroke of the trigger mechanism is hinged with a lever type fastening piece, and one end of the lever type fastening piece is positioned in the impinging stroke of the trigger mechanism, the other end fastened on the locking hook. The electromagnetic valve makes action after receiving an electrical signal. The trigger mechanism is released to strike the lever type fastening piece, which causes the other end of the fastening piece to disengage from the locking hook, so as to make the dispersed door disengage from the bondage of the releaser and open freely. The utility model can be widely applied to the dispersed door of a supermarket, a cinema, etc., where people are not allowed to go through at peacetime, but have to go through freely particularly cases.
Description
Technical field
The utility model relates to a kind of device of open and close door.
Background technology
The electrodynamic type hoist engine structure of the device of modal open and close door such as rolling door is rotated by motor drives one cylinder, with the door curtain winding up on cylinder and rolling door is opened; Otherwise close.More single-minded is can satisfy the open and close door gear of the labeled door that fire-fighting requires, as Chinese patent ZL 01 2 14680.3 disclosed " labeled door closes a release automatically " etc., the open and close door gear of these labeled doors is because its special functional requirement, so structure more complicated all.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of normally closed type egress door release simple in structure, broad-spectrum is provided.
The purpose of this utility model is achieved through the following technical solutions: normally closed type egress door release, partly constitute by the release body and the corresponding locking hook two that is installed on the door leaf that are installed on the doorframe, described release body has a housing, in housing, be provided with an electromagnetic valve and the cocking mechanism that is controlled by this electromagnetic valve, stroke front end at cocking mechanism is hinged with a lever fastener, one end of this lever fastener is arranged in the impact stroke of cocking mechanism, and the other end snaps onto on the locking hook.Snap onto on the locking hook by cocking mechanism during use and egress door is locked in normally off.When needs are opened, give signal of telecommunication of electromagnetic valve, the electromagnetic valve action, releasing trigger mechanism makes it to clash into the lever type fastener, makes the other end of lever type fastener break away from the locking hook, thereby makes egress door break away from the constraint of this release and can freely open.Again at closing time, reset after the unlatching by the hand control cocking mechanism.The control signal of electromagnetic valve can be connected to the unified control of special control centre, open and close as the uniformity of each egress door of cinema, or as with the fire alarm system networking, or provide control cabinet for oneself, probe is formed autonomous system.
Still can set an acoustic-optic alarm, when triggering electromagnetic valve unlatching normal closed gate, also trigger acoustic-optic alarm, pass through to urge people.
The utility model has the advantages that simple in structure, reliable in action, energy free consumption at ordinary times relies on pure frame for movement locking, can realize single fan or multiple leaf door interlock control easily.The egress door that can be widely used in the no thoroughfare at ordinary times of this class such as supermarket, cinema and must be able to have free passage under special circumstances; Or two units share a building high level (being a shared cover fire-fighting and a fire escape), the partition door on the shared fire escape that must be able to have free passage when requiring partition, breaking out of fire mutually at ordinary times; Or the door of special occasions uses such as recording room, control room.
Below in conjunction with embodiment content of the present utility model is done further explanation.But content of the present utility model is not limited in the content of present embodiment.

The specific embodiment
Shown in Fig. 1～3, this normally closed type egress door release partly constitutes for 4 liang by being installed in the locking hook that release body 2 on the doorframe 1 (among the figure shown in the double dot dash line) and correspondence be installed on the door leaf 3 (among the figure shown in the double dot dash line), 5 is the housing of release body among the figure, in housing 5, be provided with an electromagnetic valve 6 and the cocking mechanism 7 that is controlled by this electromagnetic valve, stroke front end at cocking mechanism 7 is hinged with a lever fastener 8, one end of this lever fastener 8 is arranged in the impact stroke of cocking mechanism, and the other end snaps onto on the locking hook 4.12 is the hand-reset handle of trigger among the figure, and 9 is the control circuit of electromagnetic valve 6, and this control circuit can set electro coupled oscillator, adopt the pulse mode power supply still can reliably move under under-voltage condition guaranteeing.15 is the signal of telecommunication input interface of the control circuit of electromagnetic valve, electromagnetic valve 6 gets electric back and produces magnetic force pulling drive link 10, thereby releasing trigger mechanism 7, cocking mechanism 7 hits an end of lever type fastener 8 under the effect of spring force, make lever type fastener 8 make the former other end that snaps onto on the locking hook 4 leave locking hook 4 around its hinge post 11 rotations, referring to Fig. 3, thereby discharge the former door leaf 3 that is in closed condition.
In described release body, also be provided with an acoustic-optic alarm that constitutes by light emitting diode 13 and loudspeaker 14.When triggering electromagnetic valve unlatching normal closed gate, also trigger this acoustic-optic alarm, pass through to urge people.
Claims (2)
1, normally closed type egress door release, it is characterized in that described release partly is made of the release body and the corresponding locking hook two that is installed on the door leaf that are installed on the doorframe, described release body has a housing, in housing, be provided with an electromagnetic valve and the cocking mechanism that is controlled by this electromagnetic valve, stroke front end at cocking mechanism is hinged with a lever fastener, one end of this lever fastener is arranged in the impact stroke of cocking mechanism, and the other end snaps onto on the locking hook.
2, normally closed type egress door release as claimed in claim 1 is characterized in that described release body also is provided with an acoustic-optic alarm.
