Abstract

The utility model discloses a windproof component structure for a rolling door. The windproof component structure comprises frames (1) which are oppositely arranged, wherein guide rails (2) are arranged on the frames (1), and two ends of a curtain piece (3) are arranged in the guide rails (2). The windproof component structure is characterized in that windproof side buckles (4) are fixedly connected at two ends of the curtain piece (3), sliding ends (5) of the side buckles (4) are arranged in a guide rail (3), rollers (6) are arranged at the upper ends and the lower ends of the sliding ends (5), the distance H1 between two rollers (6) is larger than the height H2 of an opening (7) of the guide rails. The windproof component structure for the rolling door is noiseless, has simple structure and ingenious design and can prevent the curtain piece from breaking away from the guide rails in a larger wind power condition, and the friction force of the rolling action is small.

Description

Rolling door wind-proof component structure

Technical field

The utility model relates to a kind of rolling door structure, and especially a kind of roller shutter door curtain sheet that can prevent deforms under the effect that receives external force and from guide rail, deviates from, the rolling door wind-proof component structure that situation such as cause that rolling door can't be used takes place.

Background technology

Development and maturation along with the rolling door technology; Increasing place begins to use rolling door; But there is the problem of a general character in the rolling door of generally using now: under the door opening, when the wind-force that bears when roller shutter was big, a certain amount of distortion took place in the curtain sheet under the effect of wind-force; The two ends of curtain sheet can be deviate from from guide rail, and rolling door can't normally be used.The patent No. is ZL201020246320.2; The patent that name is called " roller shutter window windproof part structure " discloses a kind of windproof structure that is applied on the roller shutter window, solved above-mentioned problem, but in use still there is certain problem in the described technical scheme of this patent; Be that motion between roller shutter and the guide rail is sliding friction; In the process of roller shutter and guide rail relative motion, long-living bigger frictional force of meeting and noise have influenced the normal use of rolling door.Therefore need a kind of novel wind-proof component or windproof structure that can address the above problem now.

Summary of the invention

The utility model is in order to solve existing in prior technology the problems referred to above; Provide a kind of simple in structure, the design ingenious; Can prevent that the curtain sheet from deviating under the bigger situation of wind-force, and roller shutter action frictional force is little from guide rail, noiseless rolling door wind-proof component structure.

The concrete solution of the utility model is: a kind of rolling door wind-proof component structure; Comprise the framework that is oppositely arranged, framework is provided with guide rail, and the two ends of curtain sheet are positioned at guide rail; It is characterized in that: the two ends of said curtain sheet are fixedly connected with windproof side and buckle; The sliding end of windproof side button is positioned at guide rail, and is provided with roller at the two ends up and down of sliding end, and the distance H 1 between two rollers is greater than the height H 2 of guide openings.

The utility model is compared with prior art, has following advantage:

The rolling door wind-proof component structure of the utility model embodiment; Simple in structure; Design ingeniously, it had both solved the roller shutter (wind-force etc.) when receiving bigger external force of traditional structure, after distortion to a certain degree takes place the curtain sheet; Deviate from from guide rail at its two ends, causes the problem that roller shutter can't operate as normal; Change the motion between roller shutter and the guide rail into rolling friction by sliding friction again, reduced frictional force, eliminated the noise that is produced in roller shutter and the guide rail movement process, make motion smooth more.And this structure is with low cost, and reliable in structure we can say that it has possessed multiple advantage, very helps applying in the art, and its market prospects are comparatively wide.

The specific embodiment

Below with the specific embodiment of accompanying drawings the utility model.Like Fig. 1, Fig. 2, shown in Figure 3: a kind of rolling door wind-proof component structure; The framework 1 that comprises pair of opposing; Its length direction offers guide rail 2 in framework 1 upper edge; The two ends of curtain sheet 3 are provided with windproof side and buckle 4, and the sliding end 5 of windproof side button 4 is positioned at guide rail 3, and promptly curtain sheet 3 is buckled 4 through windproof side and is slidingly connected with framework 1; Two ends up and down at sliding end 5 are respectively arranged with roller 6, and distance (being the height of the sliding end 5) H1 between two rollers 6 is greater than the height H 2 of guide openings 7.

The course of work of the rolling door wind-proof component structure of the utility model embodiment is following: when needs let roller shutter open or close; Start drive unit; Pack up or put down the curtain sheet 3 that is serially connected, be provided with windproof side in the termination of each curtain sheet 3 (or the curtain sheet 3 in every interval) and buckle 4, the sliding end 5 on the windproof side button 4 is positioned at guide rail 2; The roller 6 at windproof side button two ends about in the of 4 of saying so exactly is positioned at guide rail 2; In the process of curtain sheet 3 motions, roller 6 just can roll in guide rail 2, is the rolling friction that frictional force is less, noise is lower between curtain sheet 3 and the guide rail 2 like this;

When curtain sheet 3 receives bigger external force (like wind-force); Elastic deformation takes place in curtain sheet 3; The windproof side that is positioned at curtain sheet 3 two ends buckle 4 can oriented door central motion trend; But because the distance H 1 between two rollers 6 is greater than the height H 2 of guide openings 7, this structure can guarantee that windproof side button 4 can not deviate from from guide rail 2, guarantee that rolling door can operate as normal.

Claims

1. rolling door wind-proof component structure; Comprise the framework (1) that is oppositely arranged, framework (1) is provided with guide rail (2), and the two ends of curtain sheet (3) are positioned at guide rail (2); It is characterized in that: the two ends of said curtain sheet (3) are fixedly connected with windproof side and buckle (4); The sliding end (5) of windproof side button (4) is positioned at guide rail (3), and is provided with roller (6) at the two ends up and down of sliding end (5), and the distance H 1 between two rollers (6) is greater than the height H 2 of guide openings (7).
