Description
The utility model relates to a kind of fireproof door and closes a release automatically.
Chinese patent CN2239489 discloses a kind of fireproof door release that closes a function that has, and main composition comprises housing, be arranged on chain transmission in the housing closes a mechanism, click relieving mechanism and be installed in the pivoted arm that closes on the chain wheel transmission shaft of chain-drive mechanism.Rotational motion when utilization is opened the door makes the accumulation of energy of chain-drive mechanism tension stage clip, by mechanism's triggering ratchet detent mechanism of electromagnet of fire-fighting center control and so on, discharges spring that chain-drive mechanism held and can drive and close a pivoted arm and fireproof door is closed during breaking out of fire.The shortcoming of this release is the open degree of door arbitrarily can not be put to fix on a certain position, and inconvenience is used under the normal condition of non-fire.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, provides a kind of fireproof door that can arbitrarily put fixed its opening angle to close a release automatically.
The fireproof door of realizing the utility model purpose closes a release automatically, comprise housing, be installed in the chain-drive mechanism in the housing, be installed in closing a pivoted arm and being arranged on the relieving mechanism that closes between a pivoted arm and the chain-drive mechanism on the sprocket shaft of chain-drive mechanism, described relieving mechanism comprises that one is fixed in the clutch outer member on the housing, be arranged on the clutch core in the circle in the clutch outer member, be installed on the sprocket shaft and be arranged in the clutch driving wheel of clutch core, the sprocket wheel Joint of clutch core and chain-drive mechanism, and be sleeved on the sprocket shaft, having one in the internal circle position of clutch outer member cuts line groove, be provided with a compression spring at the stub end that cuts line groove, little head end has a through hole relatively, be provided with a percussion rod in the through hole, be provided with one in the cutting line groove between percussion rod and compression spring and can be connected to clutch core outer circumferential edge and the stop rod that cuts line groove between the exterior rim, be provided with one at the excellent other end of percussion and close an inspiration mechanism.
Operation principle of the present utility model is as follows:
To close an inspiration mechanism during use and be connected, make it to be controlled by fire protection control center with fire protection control center.The rotation of door leaf drives the sprocket shaft rotation by closing a pivoted arm when opening the door, sprocket shaft drives clutch driving wheel mounted thereto and rotates, driving wheel drives the clutch core and rotates towards the stub end that cuts line groove, and the sprocket wheel that is fixed in simultaneously on the clutch core also rotates the stage clip compress energy storage that makes in the chain-drive mechanism thereupon.Be stuck in clutch core outer circumferential edge and cut line groove between the exterior rim owing to the stop rod pushes up under the effect of the compression spring of the stub end that cuts line groove to the tangential slot small end, when opening the door, make the clutch core when the stub end direction that cuts line groove is rotated, can force resistance that the stop rod overcomes the compression spring to the stub end motion and finish rotation.Otherwise then can not.Therefore, no matter door is opened into arbitrary position, and the clutch core is positioned on this angle position, and the sprocket wheel affixed with the clutch core also is fixed thereupon.When breaking out of fire must be closed fireproof door, an inspiration mechanism that closes that is located at the other end of percussion rod is triggered by fire protection control center, impinge upon on the percussion rod, impinge upon on the stop rod after the percussion rod is stressed, the resistance that makes the stop rod overcome its compression spring moves and releasing clutch core and affixed with it sprocket wheel to the stub end that cuts line groove, compression spring in the chain-drive mechanism discharges the compression energy and drives the rotation of sprocket wheel and clutch core in the other direction, the clutch core drives driving wheel and rotates, driving wheel drives sprocket shaft and rotates, and the sprocket shaft drive is closed a pivoted arm and rotated and fireproof door is closed.
Closing an inspiration mechanism can be made of electromagnet transmission mechanism, gunlock device and the transmission release lever that is arranged between electromagnet transmission mechanism and the gunlock device.Providing the signal of telecommunication by fire protection control center triggers the electromagnet transmission mechanism and " pulls " gunlock device and finish pulling the trigger rod and then to the bump of stop rod.
Closing an inspiration mechanism can also adopt temperature control tube to inspire mechanism to serve as.Utilize temperature control tube bursting automatically at high temperature, make former apical grafting impinge upon the bump of realizing on the percussion rod the stop rod at the striker on the temperature control tube.
The utility model has the advantages that the open degree of door arbitrarily to be put to fix on to finish reliably on a certain position and close a function automatically.Controlled way is flexible, applicability is strong.The functional reliability height, easy to use.Can be used for various wing formula fireproof doors.
Below in conjunction with drawings and Examples essence is described in further details with novel.
