Abstract

The utility model relates to a silencing device of a rolling door orbit, which is characterized in that the cross section of a door pillar basically forms a U shape and both end edges of the door pillar respectively form a falcate guide rail. The guide rail is provided with silencing material, and the tail end edge of the guide rail wraps around and extends to form an extending edge. The guide rail and the cross section of the extending edge basically form the shape of a wrap-around connection hook, and the guide rail and the extending edge are completely coated with a layer of silencing material. Thus, the utility model obtains the purposes of collision prevention, good silencing effect and difficult shed of the silencing material.

Description

The silencing means of Coiling door track

The utility model relates to a kind of silencing means of Coiling door track.

The silencing means of a kind of Coiling door track commonly used, as shown in Figure 7, it is the approximate U type of section of this door pillar 60, its inboard forms a hook-shaped guide rail 70, and guide rail 70 interior plugs are relatively established a noise reduction bar 80; During the combination of this kind device, as shown in Figure 8, it is earlier the inboard section that forms of the dual-side end of door pillar 60 to be hook-shaped guide rail 70, noise reduction bar 80 plugs with the L type are located at hook-shaped guide rail 70 again, making it produce one cooperates closely, should rolling door commonly used up and down during start, this noise reduction smooth surface has elasticity, when its rolling door blade touches when wanting, can absorb it and touch power, and make its sound that produces reduce to minimum, reach the purpose that reduces noise, yet this kind staple is bad because of structure design, produces following shortcoming:

1, the structure design of guide rail, the noise reduction bar easily comes off, and brings inconvenience; It is that guide rail 70 with door pillar 60 inboards is designed to hook-shaped kenel, again the noise reduction bar 80 of L type is simply filled in and be located among the guide rail, yet, use through a period of time, the L type noise reduction bar 80 that simple plug is located at guide rail 70 can produce the phenomenon that comes off, and can't reach the effect that reduces noise and cause inconvenience in the use.

2, the structure design of noise reduction bar, erasure effect is not good; It is utilize L type shape noise reduction bar 70 inlay cards in the guide rail 70 of door pillar 60, the noise-reducing structure of its individual layer can't effectively reduce noise, causes erasure effect not good.

The utility model main purpose provides a kind of anti-collision, erasure effect is good and the silencing means of the Coiling door track of difficult drop-off, has anti-collision, erasure effect is good and the advantage of quieter material difficult drop-off.

The utility model is taked following design scheme for achieving the above object: the silencing means of this Coiling door track, the section of the door pillar of this device is the U type substantially, its limit, two ends respectively forms a hook-shaped guide rail, and described guide rail place establishes a quieter material, described guide rail distal edge is unrolled and is extended to form an extension edge, guide rail and extension edge section are substantially unroll to connect hook shape, and described quieter material is coated on described guide rail and the extension edge fully.Can reach anti-collision, erasure effect is good and the purpose of quieter material difficult drop-off.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, basic structure of the present utility model, it is the approximate U type of section of this door pillar 10, its limit, two ends respectively forms a hook-shaped guide rail 20, and guide rail 20 places establish a quieter material 30, its main points are that guide rail 20 distal edge are unrolled and extended to form an extension edge 21, and guide rail 20 and extension edge 21 sections are approximately

Shape, and coat one deck quieter material 30 fully at guide rail 20 and extension edge 21.

As shown in Figure 2, during the utility model manufacturing combination, it unrolls two guide rails, 20 distal edge of door pillar 10 earlier and extends to form an extension edge 21, and guide rail 20 and extension edge 21 sections are approximately

Shape is coated on quieter material 30 guide rail 20 and extension edge 21 more fully, produces one and cooperates closely.

As shown in Figure 3, when rolling door up and down during start, when its rolling door blade 40 touched the quieter material 30 of extension edge 21, its quieter material 30 can effectively absorb it and touch power, and made its sound that produces reduce to minimum, reached the effect that reduces noise.

As shown in Figure 4, when the utility model desire is embedded in wall with door pillar 10, bury the limit underground at this and establish a frame post 50, bury fixing effect underground and reach, as shown in Figure 5, when the utility model uses on center pillar 51, it is that guide rail 20 with the limit, two ends coats quieter material 30 fully with extension edge 21, and reach the effect that reduces noise, as shown in Figure 6, be the enforcement of another kenel of center pillar, it can once be bent to form iron material the form of one center pillar, and door pillar 10 guide rails 20 on an end limit form dual thickness of slab, have the effect of reinforcement.

The utility model has the advantages that:

1, the structure design of guide rail, the quieter material difficult drop-off, it is guide rail 20 distal edge on the limit, two ends of door pillar 10 to be unrolled extend to form an extension edge 21, and guide rail 20 and extension edge 21 sections are approximately

Shape, and coat one deck quieter material 30 fully in guide rail 20 and extension edge 21 produces between this guide rail 20 and the quieter material 30 and combines closely, can be because of neglectful touching do not cause quieter material to come off, and reach the structure of long service life.

2, the structure design of guide rail and extension edge, it is good to reduce noise result; It makes guide rail 20 and extension edge 21 sections be shape approximately, and coat quieter material 30 fully in guide rail 20 and extension edge 21, the structure design of this guide rail 20 and extension edge 21, make it form the kenel of two-layer quieter material 30, increase the power of touching that absorbs, make the sound of its generation reduce to minimum, reach effective reduction noise.

In sum, structure of the present utility model has anti-collision, erasure effect is good and effect such as quieter material difficult drop-off.Can thoroughly improve the shortcoming that common silencing means produces.
