Abstract
An electrically-controlled door knocker releaser comprises a shell, an electromagnet, a small deflector rod, a big deflector rod, a release stopping block, a release hook, a release hook seat, a tension spring and an inching switch. The electrically-controlled door knocker releaser is characterized in that the electromagnet is fixedly connected on the inner surface of the shell, the electromagnet is connected with the small deflector rod, the small deflector rod is matched and connected with the big deflector rod, the big deflector rod is connected with the release stopping block, the release stopping block is connected with the release hook, the release hook and the release stopping block are respectively and fixedly connected with the release hook seat, the release hook seat is fixedly connected with the inner surface of the shell, the tension spring is connected between the big deflector rod and the electromagnet, the inching switch is arranged on the side wall of the big deflector rod, the inching switch is connected with a circuit board, return springs are respectively connected in the release stopping block and the release hook, and the upper surface of the release stopping block is connected with a manual release column. The electrically-controlled door knocker releaser has the beneficial effects that the structure is simple, the installation is convenient, the outer shape is generous, the manual release column is installed, the door knocker can be released manually, and the debugging is convenient.
Description
Technical field
The utility model relates to a kind of knocker release, relates in particular to a kind of automatically controlled knocker release simple, attractive in appearance.
Background technology
In public, the occasion concentrated of visitors flowrate such as large-scale club, market and office premises, the door of escape way must be a normally open, is beneficial to the masses and evacuates when Mass disturbance takes place.But when running into the condition of a fire, need safety door to close automatically, so as not to the condition of a fire more large tracts of land spread out, effectively stop the intensity of a fire, the safety of the protection person and property.At present, in order to solve the problem of this automatic closed safe door, mostly adopt the knocker release is installed on safety door, when the condition of a fire takes place, after the sensor of release detects the condition of a fire, send a signal to electromagnet, electromagnet is received signalizing activity, discharge knocker, door has just been closed automatically like this, has stopped that the intensity of a fire further spreads.But the release complex structure on the market does not possess the manual releasing function, and Installation and Debugging can only be carried out under the state of energising, use inconvenience, and structure height are too big, influences the body of wall overall appearance.
Summary of the invention
The purpose of this utility model is to provide a kind of automatically controlled knocker release, when this release runs into the condition of a fire, discharges knocker automatically, stops fire spreading.
The utility model is achieved like this, it comprises housing, electromagnet, little driving lever, big driving lever, only put piece, break off relations, seat breaks off relations, extension spring, microswitch, it is characterized in that the fixedly connected electromagnet of shell inner surface, electromagnet connects little driving lever, the little driving lever big driving lever that is connected, big driving lever connects only puts piece, only put piece and connect unhook, break off relations and only put piece and fixedly connected the seat that breaks off relations respectively, the fixedly connected shell inner surface of seat that breaks off relations is connected extension spring between driving lever and the relay greatly, the sidewall of big driving lever has microswitch, microswitch connecting circuit plate is connected return spring respectively in only putting piece and breaking off relations, and only puts the piece upper surface and connects the manual releasing post.
Technique effect of the present utility model is: simple in structure, easy for installation, outward appearance is generous, and the manual releasing post is installed, can the manual releasing knocker, and it is convenient to debug.
