Abstract
The utility model discloses an anti-twist-off device of a torsion spring for a rolling shutter door, wherein the anti-twist-off device comprises an installation plate and a torsion spring installation groove arranged at one side of the installation plate; a ratchet is arranged at the other side of the installation plate; an axial hole is formed in the middle part of the ratchet; the axial hole is communicated with the torsion spring installation groove; a groove is arranged at the lower part of the installation plate; a pawl is arranged in the groove; and the pawl is fixed in the groove through a bolt. The anti-twist-off device disclosed by the utility model is rational in structure; the space of the installation plate is sufficiently utilized through the anti-twist-off device of the torsion spring; when the torsion spring is broken, the rolling shutter door can be prevented from falling suddenly through the pawl and the ratchet; therefore, production and property safety of people can be ensured.
Description
Technical field
The utility model relates to a kind of rolling door with the anti-device that twists off of torsion spring.
Background technology
Rolling door is to be cascaded with the movable door sheet of multi-joint, in fixing slideway, is that door is up and down rotated at the center with door top spool.Rolling door equally plays horizontal subdivision with the effect of wall; It is made up of curtain plate, seat board, guide rail, mount pad, spool, casing, control cabinet, door-rolling machine, stop, lintel, 13 parts such as manual speed relieving pass device, press button and safeties, generally is installed in inconvenient position of adopting the wall separation.Rolling door is applicable to public place or dwelling houses such as the commercial shop front, garage, market, hospital, industrial enterprise.Especially door opening is bigger, and inconvenience is installed the place of ground door body and played convenient, fast unlatching effect.
The phenomenon that torsion spring on the rolling door may occur twisting off after long-term the use has bigger potential safety hazard.After torsion spring twisted off, rolling door can fall suddenly under the effect of gravity, causes burst accident, influences people's safety of life and property.
Summary of the invention
To the problems of the prior art, the purpose of the utility model is to provide a kind of rolling door with the anti-device that twists off of torsion spring.
To achieve these goals, the technical scheme of the utility model is: a kind of rolling door twists off device with torsion spring is anti-, comprises installing plate, is arranged on the torsion spring mounting groove of installing plate one side; Said installing plate opposite side is provided with ratchet; The ratchet middle part has axis hole, and this axis hole communicates with the torsion spring mounting groove, and the installing plate bottom is provided with a groove; One ratchet is set in the groove, and ratchet is through being bolted in the groove.
Further, said groove and installing plate are structure as a whole, and are stamped to form by installing plate.
The utility model is rational in infrastructure, and torsion spring prevents twisting off the space that device has made full use of installing plate, and when fracture took place torsion spring, pawl-and-gearing can stop rolling door to fall suddenly, has guaranteed people's production and property safety.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2, a kind of rolling door twists off device with torsion spring is anti-, comprises installing plate 3, is arranged on the torsion spring mounting groove 5 of installing plate 3 one sides; Said installing plate 3 opposite sides are provided with ratchet 4; Ratchet 4 middle parts have axis hole 6, and this axis hole 6 communicates with torsion spring mounting groove 5, and installing plate 3 bottoms are provided with a groove; One ratchet 2 is set in the groove, and ratchet 2 is fixed in the groove through bolt 1; Said groove and installing plate 3 are structure as a whole, and are stamped to form by installing plate 3.
The utility model is rational in infrastructure, and torsion spring prevents twisting off the space that device has made full use of installing plate, and when fracture took place torsion spring, pawl-and-gearing can stop rolling door to fall suddenly, has guaranteed people's production and property safety.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into protection scope of the present invention.
