Description

Technical Field

[0001] The utility model relates to the technical field of garage doors, and particularly to a garage door with low damping and high sealing performance. Background Art

[0002] Since the structure of a rolling door is made up of multiple curtain sheets and the shafts connecting the curtain sheets, and the curtain sheets can rotate relative to each other around the shafts, it is suitable as a garage door. Generally, a winding mechanism and a storage bag for accommodating the rolling door in the retracted state are provided at the top of the door frame, and the two sides of the door frame are the tracks for the rolling door. To increase the strength of the door, the curtain sheets of the rolling door are generally C-shaped or U-shaped. Therefore, the tracks and the curtain sheets cannot fit well. Currently, brushes are generally provided in the tracks to make the tracks and the rolling door reach a relatively sealed state.

[0003] However, when the rolling door opens and closes, friction is generated between the brushes and the surface of the curtain sheets. When the brushes are longer and denser, the frictional force is greater, but the sealing performance is also better. When the brushes are shorter and sparser, the frictional force is smaller. Therefore, how to balance the damping force of the tracks and the sealing performance of the tracks is an urgent problem to be solved. Summary of the Utility Model

[0004] In view of the technical problems existing in the garage door in the prior art, a technical solution is proposed in the first aspect of the present utility model. A garage door with low damping and high sealing performance includes a rolling door body, a guide rail structure, and a winding mechanism. The first end of the rolling door body is connected to the winding mechanism, and the second end is a free end. The winding mechanism is used to wind and unwind the rolling door body. The guide rail structure is arranged on both sides of the rolling door body, so that the free end of the rolling door body moves along the guide rail structure.

[0005] Wherein, the guide rail structure is provided with a guiding groove and a slot opening. The side edge of the rolling door body extends into the guiding groove from the slot opening. A pair of elastic sealing structures are arranged in the guiding groove, and the pair of elastic sealing structures are respectively attached to the front and back surfaces of the side edge of the rolling door body. The elastic sealing structure includes an elastic strip and a brush connected to the surface of the elastic strip. The elastic strip is configured to deform according to the concave and convex contours on the surface of the rolling door body.

[0006] Preferably, along the thickness direction of the rolling door body, the elastic strip includes a first end face and a second end face. The first end face is connected to the inner wall of the guiding groove, and the second end face faces the rolling door body. The brush is connected to the second end face.

[0007] Preferably, the brush is strip-shaped and includes a base layer and a hair layer. The base layer is connected to the second end face of the elastic strip, and the hair layer is connected to the base layer. The thickness ratio of the base layer to the hair layer is 1:4 - 1:5.

[0008] Preferably, along the width direction of the rolling door body, the elastic strip includes a third end face and a fourth end face, and the third end face and the fourth end face are not in contact with the guiding groove.

[0009] Preferably, the elastic strip includes a hollow rubber strip, and the cross-sectional shape of the elastic strip is rectangular.

[0010] Preferably, in the direction parallel to the rolling door body, the wall thickness of the elastic strip is smaller than the wall thickness in other directions.

[0012] Preferably, the rolling door body includes a plurality of curtain sheets and a connecting shaft connecting two adjacent curtain sheets, and guide wheels are provided at both ends of the connecting shaft, and the guide wheels slide on the inner wall of the guiding groove.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0020] In order to better understand the technical content of the present invention, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0021] Combined withFigure 1 As shown in the figure, a technical solution is proposed in the first aspect of the present utility model. A garage door with low damping and high sealing includes a rolling door body 10, a guide rail structure 20, and a winding mechanism 30. The first end of the rolling door body 10 is connected to the winding mechanism 30, and the second end is a free end. The winding mechanism 30 is used to wind and unwind the rolling door body 10. The guide rail structure 20 is arranged on both sides of the rolling door body 10, so that the free end of the rolling door body 10 moves along the guide rail structure 20.

[0022] More specifically, the rolling door body 10 is composed of a plurality of curtain sheets 11 and a connecting shaft 12 connecting adjacent two curtain sheets 11. Adjacent curtain sheets 11 can rotate relative to each other through the connecting shaft 12. The winding mechanism 30 includes a motor and a winding shaft. The curtain sheet 11 at the uppermost end is connected to the winding shaft. When the motor drives the winding shaft to rotate, the curtain sheets 11 are wound on the surface of the winding shaft, so that both ends of all the curtain sheets 11 slide within the track structure 20.

[0023] Among them, in combination with Figure 2 As shown in the figure, the guide rail structure 20 is provided with a guide groove 21 and a notch 22. The side edge of the rolling door body 10 extends into the guide groove 21 from the notch 22.

[0024] Optionally, the track structure 20 is pre-bent into the shape shown in the figure. The guide groove 21 is generally rectangular, and the width of the notch 22 is smaller than the width of the guide groove 21, so that the side edge of the rolling door body 10 can extend into the guide groove 21. In order to reduce the damping and improve the stability of the rolling door body 10 during winding and unwinding, guide wheels 13 are provided at both ends of the connecting shaft 12, and the guide wheels 13 slide on the inner wall of the guide groove 21.

[0025] In this way, the guide wheels 13 on the inner wall of the guide groove 21 can limit the shaking of the connecting shaft 12 in the relatively wide guide groove 21, making the rolling door body 10 slide more stably in the guide groove 21.

[0026] Furthermore, in combination with Figure 2-4 As shown in the figure, a pair of elastic sealing structures are provided in the guide groove 21. The pair of elastic sealing structures are respectively attached to the front and back sides of the side edge of the rolling door body 10. The elastic sealing structure includes an elastic strip 23 and a brush 24 connected to the surface of the elastic strip 23. The elastic strip 23 is arranged to be deformed according to the concave and convex contour of the surface of the rolling door body 10.

[0027] In this way, the elastic sealing structure in the guide groove 21 has a stronger fitting ability to the surface of the rolling door body 10. When the rolling door body 10 slides relative to the track structure 20, the friction of the rolling door body 10 can be reduced. When the rolling door body 10 is stationary, the sealing performance between the rolling door body 10 and the track can be increased, especially with better wind resistance.

[0028] Such as Figure 4As shown, when the curtain sheet 11 is closer to the inner elastic strip 23, the compression amount of the inner elastic strip 23 is greater. When the curtain sheet 11 is closer to the outer elastic strip 23, the compression amount of the outer elastic strip 23 is greater. In this way, it can be ensured that the brush 24 always adheres tightly to the surface of the rolling door body 10 without generating a large contact pressure.

[0029] In an alternative embodiment, along the thickness direction of the rolling door body 10, the elastic strip 23 includes a first end face and a second end face. The first end face is connected to the inner wall of the guide groove 21, and the second end face faces the rolling door body 10. The brush 24 is connected to the second end face.

[0030] Preferably, the brush 24 is strip-shaped and includes a base layer and a hair layer. The base layer is connected to the second end face of the elastic strip 23, and the hair layer is connected to the base layer. The thickness ratio of the base layer to the hair layer is 1:4 - 1:5.

[0031] Optionally, the base layer is a nylon or polyethylene layer. Multiple bristles of the hair layer are inserted into the base layer when the base layer is in a molten state and are finally fixed inside the base layer after the base layer is formed to prevent the bristles from falling off. The bristles can adhere tightly to the uneven surface of the rolling door body 10.

[0032] Furthermore, along the width direction of the rolling door body 10, the elastic strip 23 includes a third end face and a fourth end face. The third end face and the fourth end face are not in contact with the guide groove 21.

[0033] In this way, when a local part of the elastic strip 23 is subjected to pressure, it can deform in the direction of the third end face and the fourth end face, that is, it is recessed in the thickness direction of the rolling door body 10, reducing the pressure of the brush 24 on the surface of the rolling door body 10.

[0034] In a preferred embodiment, the elastic strip 23 includes a hollow rubber strip, and the cross-sectional shape of the elastic strip 23 is rectangular.

[0035] In this way, the first end face of the elastic strip 23 can be adhered to the inner wall of the guide groove 21, and the second end face of the elastic strip 23 can be adhered to the brush 24, having a larger connection area.

[0036] Furthermore, as shown in Figure 2-4 In the direction parallel to the rolling door body 10, the wall thickness of the elastic strip 23 is smaller than the wall thickness in other directions. This is beneficial for the elastic strip 23 to deform in the direction parallel to the rolling door body 10 after being pressed, enabling a larger deformation space in the direction perpendicular to the rolling door body 10, with a smaller surface pressure on the rolling door body 10 and better fitting performance.

[0037] As shown in Figure 2 A sealing cavity 231 is formed inside the hollow rubber strip. By setting the inside of the hollow rubber strip as a sealed structure, the fatigue resistance and service life of the hollow rubber strip can be increased.

[0038] Combined with the above embodiments, the elastic sealing structure is arranged in the track of the utility model. The elastic sealing structure includes an elastic strip and a brush. Due to the high elasticity and high resilience of the elastic strip itself, the brush can always keep in contact with the surface of the rolling door body, and can reduce the contact pressure, so that the rolling door body has small damping and high sealing performance when being retracted and extended.

[0039] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the claims.
