Abstract
The utility model relates to a prevent that drive chain from becoming electric roller shutter of pine, including the door body and mounting panel, the rotatable main shaft that is equipped with on the mounting panel, the door body coupling the main shaft the tip cover of main shaft has a big sprocket still be equipped with the motor on the mounting panel, the output of motor passes through the roller chain and connects big sprocket, the motor drives thereby big sprocket turns realizes family of a general's body and collects on the main shaft or the family of a general body follow put down on the main shaft just correspond on the mounting panel position department in the roller chain is equipped with the elasticity in certain extent's that keeps the roller chain regulator. The beneficial effects of the utility model are that: add a regulator that keeps the elasticity in certain extent of roller chain in the roller chain, can keep the elasticity of roller chain to organize the life of phenomenon, extension shutter door at a fixed within range, the card when preventing the shutter door switching.
Description
Technical field
This utility model is related to shutter door field and in particular to a kind of electric rolling door preventing driving chain from fluffing.
Background technology
The operation principle of general shutter door is as follows: motor drives big sprocket wheel by roller chain, and big sprocket wheel drives main shaft
Rotate and realize the enabling of shutter door door body and close the door.There is following defect in said structure: because roller chain and sprocket wheel are
Metal is fabricated by, easy to wear in use, causes the elastic of roller chain to fluff, causes the enabling of shutter door and close the door
Easily it is stuck, using not smooth.
Utility model content
In sum, in order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model is offer one
Plant the electric rolling door preventing driving chain from fluffing.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of electric rolling preventing driving chain from fluffing
Gate, including door body and supporting plate, described supporting plate is rotatably provided with main shaft, and described door body connects described main shaft, in institute
The end stating main shaft is cased with big sprocket wheel, is additionally provided with motor on described supporting plate, and the outfan of described motor passes through roller chain
Connect described big sprocket wheel, described motor drives described big sprocket wheel to rotate thus realization door body is collected on described main shaft or will
Door body is put down from described main shaft, is provided with holding roller chain at the position on described supporting plate and in corresponding described roller chain
The elasticity of bar actuator within the specific limits.
The beneficial effects of the utility model are: the elasticity having added a holding roller chain in roller chain is certain
In the range of actuator, the elasticity that roller chain can be kept in the scope of a fixation, prevent shutter door opening and closing when
Card group phenomenon, extends the service life of shutter door.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described actuator includes connecting rod, and described connecting rod is on described supporting plate, divides at the two ends of described connecting rod
It is not provided with and rotatably can be provided with respectively on described support and described roller chain upper and lower along the support of rod slide
The minor sprocket of contact；
Spring is also cased with described connecting rod, the two ends of described spring are respectively held against the support being in described connecting rod two ends,
In the presence of described spring force, described minor sprocket withstands roller chain up and down thus ensureing the elasticity of roller chain.
Beneficial effect using above-mentioned further scheme is: the elasticity realizing roller chain is in holding certain limit.
Further, the manual-chain being turned manually is provided with described motor.
Beneficial effect using above-mentioned further scheme is: realizes being opened and closed manually shutter door.
Brief description

Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in figure 1, a kind of electric rolling door preventing driving chain from fluffing, including door body 1 and supporting plate 2, described
Main shaft 3 is rotatably provided with frame plate 2, described door body 1 connects described main shaft 3, is cased with big sprocket wheel 4 in the end of described main shaft 3,
Motor 5 is additionally provided with described supporting plate 2, the outfan of described motor 5 connects described big sprocket wheel 4 by roller chain 6, described
Motor 5 drives described big sprocket wheel 4 to rotate thus realizing door body 1 is collected on described main shaft 3 or by door body 1 from described main shaft
Put down on 3, be provided with, at the position on described supporting plate 2 and in corresponding described roller chain 6, the elasticity keeping roller chain 6
Actuator within the specific limits.
As shown in Fig. 2 described actuator includes connecting rod 7, described connecting rod 7 is on described supporting plate 2, in described connecting rod 7
Be respectively arranged at two ends with can along connecting rod 7 slide support 8, described support 8 is rotatably provided with and described roller chain respectively
The minor sprocket 9 of bar 6 upper and lower contact.Spring 10 is also cased with described connecting rod 7, the two ends of described spring 10 are respectively held against
It is in the support 8 at described connecting rod 7 two ends, described minor sprocket withstands roller chain 6 about 9 in the presence of described spring 10 elastic force
Thus ensureing the elasticity of roller chain 6.In sum, added the elasticity of a holding roller chain 6 in roller chain 6
Actuator within the specific limits, the elasticity that can keep roller chain 6, in the scope of a fixation, prevents shutter door from opening
Card group phenomenon when closing, extends the service life of shutter door.
The manual-chain 11 being turned manually is additionally provided with described motor 5, is opened manually by pulling manual-chain 11
Closed-book gate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
