Abstract

The utility model relates to a low noise roll door, which comprises a door body (6), a door frame (1) which is arranged on the lateral side of the door body (6), a longitudinal guide rail (2) which is arranged on the door frame (1) and a central shaft (8) which is positioned on the top part of the utility model, wherein, both lateral sides of the door body (6) are inserted into the guide rail (2). The utility model is characterized in that a torsion spring (5) is sheathed on the central shaft (8), one end of the torsion spring (5) is fixed on the central shaft (8), and the other end of the torsion spring (5) is fixed on a roll wheel (4) which is sheathed on the central shaft (8); furthermore, the roll wheel (4) is connected to the top end of the door body (6), wherein, both lateral parts of the door body (6) are coated with silencing belts (3). Because noises generated by the friction of the lateral parts of the door body and the door frame during the movement process of the roll door are maximal noises, and therefore, after the position is coated with the silencing belts, noises can be reduced greatly.

Description

The low noise rolling door

The utility model relates to a kind of rolling door.

In the prior art, rolling door comprises a body, be arranged at the side of described door body door frame, be arranged at longitudinal rail on the described door frame, be positioned at the central axis at top, the dual-side of described door body is inserted in the described guide rail, the door body last move or folding process in can produce strong noise, bigger to people's on every side life, work influence.

The purpose of this utility model is to provide a kind of low noise rolling door that can reduce noise.

The technical solution of the utility model is: a kind of low noise rolling door, comprise a body, be arranged at the side of described door body door frame, be arranged at longitudinal rail on the described door frame, be positioned at the central axis at top, the dual-side of described door body is inserted in the described guide rail, be with torsion spring on the described central axis, one end of described torsion spring is fixed on the central axis, the other end of torsion spring is fixed on the rolling wheel that is enclosed within on the central axis, described rolling wheel is connected with the top of door body, and the both sides of described door body are coated with the noise reduction band.

The utility model compared with prior art has following advantage:

Because in the moving process of rolling door, therefore the sidepiece of door body and the fricative noise maximum between the door frame can significantly reduce noise after this position is coated with the noise reduction band, seldom increase cost.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a structural front view of the present utility model; Wherein:

[1], door frame; [2], guide rail; [3], noise reduction band; [4], rolling wheel; [5], torsion spring; [6], door body; [7], motor; [8], central axis; [9], directive wheel;
