Abstract
The utility model provides a control mechanism for a fireproof door releaser with a ratchet and pawl mechanism. The pressure spring seat is pressed on the temperature control pipe and is connected with a pawl of the releaser through a transmission rod. The temperature control pipe is burst to make room for the space occupied by the temperature control pipe by utilizing the rise of the environmental temperature when a fire disaster happens, and the pressure spring seat is displaced under the action of the pressure spring to drive the pawl to act and complete the release. Simple structure, easy manufacture and automatic and reliable control.
Description
The utility model relates to a kind of controlling organization of labeled door release.
The controlling organization of existing labeled door release mostly be electronic type or electromechanical, in the magnet control structure disclosed in 91230148.1 patents (notification number CN2107984U), the signal of telecommunication that receives Fire Services Communication Centre by electromagnet moves electromagnet to start the ratchet on the ratchet that is locked in release and plays release action as me.The deficiency of the ratchet controlling organization of this electromagnet type is to use range limited, then can't use in the place or the non-transformer warehouse at no fire-fighting center.
The purpose of this utility model is for above-mentioned labeled door release provides another kind of controlling organization, and this controlling organization, reaches limit value in environment temperature and can start ratchet automatically and make release work as the signalizing activity source with temperature control tube.
The temperature control mechanism of labeled door release of the present utility model comprises an erection support, be arranged on the stage clip in the bearing and the press spring base that joins with stage clip and be arranged on the temperature control tube of the press spring base other end with respect to stage clip, and the elastic force that described press spring base overcomes stage clip is crimped on the temperature control tube and by a drive link and is connected with the ratchet of release.When breaking out of fire makes the environment temperature rising reach the limit value of temperature control tube, temperature control tube breaks voluntarily, abdicate the former locus that occupies, the former press spring base that is pressed on the temperature control tube then is subjected to displacement under the effect of stage clip, the drive link that is attached thereto is movement therewith also, the pulling ratchet breaks away from ratchet, finishes release.
Environment temperature this phenomenon that raises when the utility model utilizes breaking out of fire, release is controlled in the signalizing activity source of selecting for use temperature control tube to serve as the labeled door release, has advantage simple in structure, that making is easy, with low cost and breaking out of fire is controlled automatically, also make release not be subjected to the constraint of electricity simultaneously, greatly reduce requirement to service condition, expand the scope of application of release, can be widely used in the labeled door in some no Fire Services Communication Centres and non-transformer warehouse.
Embodiment:
Fig. 1 structural representation of the present utility model
The vertical view of Fig. 2 Fig. 1
As shown in Figure 1, 2, erection support is made of a pipe 1 and installing rack 2, be installed in release (among the figure shown in the chain-dotted line) housing, certainly also can be arranged on the outer appropriate location of housing, stage clip 3 and press spring base 4 are arranged in the garden pipe 1 and can slide in the pipe of garden, temperature control tube 5 can be selected commercially available temperature-sensitive glass marble for use, one end withstands on installing rack end, the other end apical grafting end at press spring base, this installation site stage clip is the compress energy storage shape, is connected with the ratchet 8 of release with drive link 7 with a screw 6.When environment temperature rose to the qualification system of temperature-sensitive glass marble during breaking out of fire, the temperature-sensitive glass marble burst voluntarily, abdicates the position, and press spring base moves right under the effect of stage clip, drove ratchet releases ratchet by drive link.
Be provided with one and pull key 9 on drive link, and a groove 10 is set, screw 6 passes this groove and is fixed on the press spring base, when desiring to make release to discharge in the no condition of a fire, can pull key by spur this to right, then can make drive link moving and press spring base is motionless.In bracket end the glass marble supporting seat 11 of an adjustable screw-type is set, can regulates the force-bearing situation of glass marble.
Claims (2)
1, a kind of temperature control mechanism with labeled door release of ratchet and pawl arrangement, it is characterized in that described temperature control mechanism comprises an erection support, is arranged on the stage clip in the erection support and the press spring base that joins with stage clip and is arranged on the temperature control tube of the press spring base other end with respect to stage clip, the elastic force that described press spring base overcomes stage clip is crimped on the temperature control tube and by a drive link and is connected with the ratchet of release.
2, the temperature control mechanism of labeled door release as claimed in claim 1 is characterized in that also being provided with one and pulls key and have a groove on described drive link.
