Abstract
The utility model belongs to the technical field of industrial quick rollershutterdoor instruments and particularly relates to a tear resisting mechanism for a flexible quick roller shutter door. The tear resisting mechanism for the flexible quick roller shutter door comprises a door body frame; a bolt is arranged on one side of the door body frame; a spring is arranged on the bolt; one end of the spring is connected with the bolt; the other end of the spring is connected with the door body frame; the bolt penetrates through one side of the door body frame, extends to the other side of the door body frame and then is connected to a track clamping part; the track clamping part can pull the bolt to move. The tear resisting mechanism disclosed by the utility model has the advantages of extremely-strong wind resisting effect, simple structure and reasonable design.
Description
Technical field
The utility model belongs to industrial quick rolling-door apparatus technical field, relates in particular to a kind of anti-tearing mechanism of flexible quick rolling-door.
Background technology
Flexible quick rolling-door extensively adopts at the passage place of the cleanrooms such as food, medicine.The Men Tiwei tension force cloth of flexible quick rolling-door.Because tension force cloth is out of shape greatlyr under the effect of wind load, can makes door curtain de-orbit, thereby lose the effect of air lock inner air and outer air.And the common wind resistance practice adopting is at present to widen door body in orbit and increase bottom girder deadweight.But this processing method exists defect: in the large situation of door body span, the wind resistance effect being risen is undesirable, and especially, when fitful wind, the moment stress of the tearing of wind load opposite house body tension force cloth is larger, thereby is easy to destroy door body.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of anti-tearing mechanism of flexible quick rolling-door is provided, and its technical scheme is as follows:
A kind of anti-tearing mechanism of flexible quick rolling-door, the anti-tearing mechanism of described flexible quick rolling-door comprises door bulk frame, one side of described door bulk frame is provided with bolt, described bolt is provided with spring, one end of described spring is connected with bolt, the other end of described spring is connected with door bulk frame, and described bolt is connected with track fastener extend to the opposite side of door bulk frame through a side of door bulk frame after, and described track fastener can pull bolt movable.
Optimal way is to be provided with pad between described spring and door bulk frame.
The diameter of bolt of the present utility model and quantity can be adjusted according to local wind load size.
The utility model when in use, be arranged with track, and track is connected with limit row chain in track fastener, and limit row chain is connected with door body tension force cloth.
The anti-tearing mechanism of the flexible quick rolling-door that the utility model provides, the effect of track fastener is to be connected with door bulk frame, makes can play and accept between track and door bulk frame.Track fastener is connected with door bulk frame by bolt, and is arranged with spring on bolt, thereby makes a body tension force cloth when wind load strengthens, and track and track fastener are subject to a pulling force for body tension force cloth, thereby pressuring spring is done horizontal movement; When wind load disappears, under spring action, door body tension force cloth reverts to original state again.So, by bolt and spring, when fitful wind, can reduce the moment stress of the tearing of opposite house body tension force cloth.
Between spring described in the utility model and door bulk frame, be provided with pad.By pad, can well make spring when being subject to power, act on pad, make between spring and door bulk frame, to there is good buffering.
Wind resistance effect of the present utility model is extremely strong, simple for structure, reasonable in design.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of anti-tearing mechanism of flexible quick rolling-door, the anti-tearing mechanism of described flexible quick rolling-door comprises door bulk frame 1, one side of described door bulk frame 1 is provided with bolt 2, described bolt 2 is provided with spring 3, one end of described spring 3 is connected with bolt 2, the other end of described spring 3 is connected with door bulk frame 1, and described bolt 2 is connected with track fastener 4 extend to the opposite side of door bulk frame 1 through a side of door bulk frame 1 after, and described track fastener 4 can pull bolt 2 activities.Between described spring 3 and door bulk frame 1, be provided with pad 5.
The utility model when in use, be arranged with track, and track is connected with limit row chain in track fastener, and limit row chain is connected with door body tension force cloth.
Door bulk frame is to be formed by hot-dip galvanizing sheet steel rolling; Track fastener is to be formed by hot-dip galvanizing sheet steel rolling, and track fastener and door bulk frame are contour; Door bulk frame and track fastener are joined together by bolt and spring, and track fastener is used along vertical uniform being bolted on doorframe of door bulk frame; One end of spring is connected with bolt, and the other end of spring is connected with door bulk frame, between spring and door bulk frame, pad can be set.
During original state, track fastener and door bulk frame fit together.When wind action is during in door body, door body tension force cloth produces a suspension cable and is equally out of shape, thereby the stressed limit row chain that makes of door body tension force cloth is stressed.Limit row chain stops a body tension force cloth to pull in track in orbit.When wind load strengthens, the stressed bolt that pulls of track and track fastener, track fastener is separated with door bulk frame, and bolt pressuring spring is done horizontal movement; When wind load disappears, under spring action, bolt is returned to initial position, thereby door body tension force cloth reverts to original state again.
