Abstract
A kind of mute rolling door, including doorframe, transmission mechanism and door body, the door body is set in doorframe, the doorframe includes door guide groove and containing case, and the door guide groove has two arranged in parallel straight to stile, is provided with containing case above two stiles, the transmission mechanism is set on containing case, the mute pulley that sliding is connected on a guide groove is provided at left and right sides of the door body, the mute pulley includes bearing assembly, nylon outer ring, and the bearing assembly is wrapped with nylon outer ring.Since the material of the outer ring of the mute pulley of the utility model is nylon, the sound of pulley and the sliding sending of door guide groove can be effectively reduced；The setting of acoustical cotton layer, groove circumferentially, vibration damping sheet and soft leather strap, convenient for reducing the grating between rolling door door piece, the more noise that further smaller rolling door sliding produces, reduces to extraneous noise pollution, to substantially improve the working environment using rolling door.
Description
Technical field
The utility model relates to a kind of rolling door technical fields, in particular to a kind of mute rolling door.
Background technique
With the development of the society, electric rolling door has become factory, the essential tool in parking lot and market, entirety is certainly
Dynamicization operation.But due to rolling door and collision on the ground when the friction between pulley and door guide groove, rolling door land and rolling door door piece it
Between friction, very big noise is always issued in switch on/off electric rolling door.
Utility model content
In order to overcome the shortcomings of that existing electric rolling door has issued very big noise, the utility model provides a kind of mute volume
Door.
To achieve the goals above, technical solution adopted in the utility model is: a kind of mute rolling door, including doorframe,
Transmission mechanism and door body, the door body are set in doorframe, and the doorframe includes door guide groove and containing case, and the door guide groove has
Two is arranged in parallel straight to stile, containing case is provided with above two stiles, the transmission mechanism is set on containing case, described
The mute pulley that sliding is connected on a guide groove is provided at left and right sides of door body, the mute pulley includes bearing assembly, Buddhist nun
Imperial outer ring, the bearing assembly are wrapped with nylon outer ring.
Further, the surface of the nylon outer ring is equipped with antiskid thread.
Further, groove circumferentially is provided on the outer surface of the bearing assembly.
Further, the door guide groove inner wall is provided with acoustical cotton layer.
Further, door body lower end is provided with vibration damping sheet.
Further, the material of the vibration damping sheet is rubber.
Further, the door body is made of several pieces, and soft leather strap is provided between door piece and door piece.
The utility model has the advantages that
Since the material of the outer ring of the mute pulley of the utility model is nylon, pulley can be effectively reduced and door guide groove is sliding
The dynamic sound issued；Door guide groove inner wall is provided with acoustical cotton layer, and the noise generated when pulley and the friction of door guide groove can be absorbed, into
One step reduces the noise of door body sliding；The setting of groove circumferentially increases the binding force of nylon outer ring and bearing；Subtract
The setting of shake piece facilitates the sound for reducing door body and collision on the ground issues；The setting of soft leather strap, convenient for reducing rolling door door piece
Between grating, the more further noise of smaller rolling door sliding production reduces to extraneous noise pollution, thus significantly
Improve the working environment using rolling door.
