When required, the utility model can also be started manually.
Description
Technical field
The utility model relates to the automatic releasing device of a kind of fire resistance rolling shutter door machine, relates in particular to a kind of automatic releasing device of fire resistance rolling shutter door machine that can start releasing device by design temperature automatically.
Background technology
The automatic releasing device of existing fire resistance rolling shutter door machine has with spring and temperature control glass marble or low-melting alloy control slide block, when temperature rises to design temperature, the temperature control glass marble breaks or low-melting alloy fusing causes the spring driving sliding block, thereby stir main frame and pull hook, the roller shutter door machine braking is thrown off, and rolling door descends automatically under the effect of deadweight and closes.
The shortcoming of prior art is that slide block directly promotes to pull hook, and this automatic releasing device must be arranged on the main frame, thereby installs the shortage flexibility.
Summary of the invention
The utility model provides a kind of fire resistance rolling shutter door machine temperature control releasing device, can solve the shortcoming of above-mentioned existing fire resistance rolling shutter door machine temperature control releasing device, can start the fire resistance rolling shutter door releasing device automatically at design temperature, and can be installed in anywhere flexibly, easy for installation.When needs, can also manually boot this device.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model is a kind of fire resistance rolling shutter door machine temperature control releasing device, comprises base plate, slide block, temperature control glass marble, spring etc., and it is characterized in that: base plate is fixed in the bottom surface; Be provided with spring between base plate and the slide block; The temperature control glass marble is resisted against the retaining that is provided with on the base plate and supports between the piece to the retaining that is provided with on piece and the slide block; One end of steel wire tightrope presses in slide block, and the other end is fixed in the main frame braking and pulls hook.
The end of above-mentioned steel wire tightrope is established a screw rod, and this screw rod passes the through hole established on the slide block wall and screws togather with a nut that is resisted against the slide block end face.
Above-mentioned spring is extension spring, also can be stage clip, is arranged between slide block and the base plate, and the retaining that the temperature control glass marble is resisted against be provided with on the base plate supports the retaining that is provided with on piece and the slide block and supports between the piece, thereby makes base plate and slide block be in relatively-stationary state at normal temperatures.Be equipped with the chance thermally-expansible liquid in the temperature control glass marble, environment temperature is elevated to a certain degree, and the temperature control glass marble can break and cause slide block relatively base plate motion and drive the motion of steel wire tightrope and the braking of pulling main frame pulls hook under spring action.Owing to use the braking of steel wire tightrope pulling main frame to pull hook, therefore as long as change the length of steel wire tightrope, this device can be installed in the place that needs rather than necessarily be installed on the main frame, and is easy for installation flexible, and the steel wire tightrope also can be used for manually controlling under normal temperature pulling hook.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, the utility model embodiment 1 shown in Figure 2, base plate 1 is fixed on the bottom surface by bolt 111, and the bottom surface can be the correct position that needs arbitrarily.Be installed with plate 11 by bolt 112 on the base plate 1, plate 11 has retaining upwards and supports piece 113.Slide block 2 is positioned on base plate 1 and the plate 11, hollow in the slide block 2, and left and right sides wall is provided with through hole, and slide block 2 upwards is provided with retaining and supports piece 21.Extension spring 4 one ends are arranged on the left wall of slide block 2, the other end is arranged on the right wall of base plate 1, extension spring 4 is stretched by slide block 2 and base plate 1, because base plate 1 is fixed on the bottom surface, the elastic force of extension spring 4 makes slide block 2 that the trend that moves right be arranged, temperature control glass marble 3 is resisted against retaining and supports between the piece 113 to piece 21 and retaining, makes slide block 2 and base plate 1 be in relatively-stationary state.Steel wire tightrope 8 passes the through hole on the slide block 2 left walls, steel wire tightrope 8 right-hand members are a screw rod 81, screw rod 81 passes the through hole on the slide block 2 right walls, and screw togather with a nut 5, nut 5 is resisted against slide block 2 right sides, screw rod 81 ends have a draw ring 82, and steel wire tightrope 8 left ends are fixed in the main frame braking and pull hook 6, and the main frame braking pulls hook 6 control rolling door arrestment mechanisms 7.When on fire, environment temperature raises, and the expansion of liquids in the temperature control glass marble 3 is to design temperature, temperature control glass marble 3 breaks, can't support piece 21 by the contact retaining, slide block 2 moves right under the effect of extension spring 4, promotes nut 5, it also is that steel wire tightrope 8 moves right that nut 5 drives bolt 81, pull hook 6 startup rolling door arrestment mechanisms 7 thereby start the main frame braking, the rolling door braking is thrown off, and rolling door descends voluntarily under the effect of deadweight and closes.Rotating nut 5 can be adjusted the tightness of steel wire tightrope 8.
The utility model uses the steel wire tightrope to connect slide block and pulls hook with the main frame braking, so base plate can be fixed on the suitable bottom surface that makes things convenient for the position, and must be arranged on the main frame unlike the prior art base plate.Easy for installation flexible.At normal temperatures, the steel wire tightrope can work independently, and uses as manual stay cord.
As Fig. 3, the utility model embodiment 2 of 4 differently with embodiment 1 is to have used stage clip 4 ', and stage clip 4 ' contact is between the right wall of the left wall of base plate 1 ' and slide block 2 ' and make slide block 2 ' have the trend that moves right.Present embodiment 2 is compacter more than embodiment 1 structure, and size is littler, therefore installs also more convenient.
