Description

Technical Field

[0001] The present application relates to the field of sunshade equipment, and in particular to a guide rail and sunshade equipment containing a labor-saving lever. Background Art

[0002] Sunshade equipment, especially roller blinds, should play the role of windproof. Guide rails are mainly set on both sides of the curtain. The guide rails are mainly used to place the parts for fixing the curtain and the corner code of the windproof roller blind cover. The material of the guide rail in the industry is mainly aluminum alloy. Due to the needs of installation and debugging, the guide rail is generally designed as a split guide rail, that is, the main body, cover body and fasteners or decorative strips. When the guide rail is installed, the main body of the guide rail will be fixed before the cover body, and then the parts for fixing the curtain will be placed. Then the guide rail cover will be fixed to the main body of the guide rail by buckles or screws, and finally the decorative cover will be installed to hide the fasteners and assembly. Due to installation and debugging and replacement of accessories, the guide rail cover needs to be disassembled and assembled repeatedly. At present, the mainstream practice in the industry is to set screws to fix and then design a buckle decorative cover to hide the screw holes. If the material of this guide rail is aluminum alloy, due to the high hardness of aluminum, the double buckle design is difficult to disassemble after buckling. Moreover, the buckle decorative cover must be elastically deformed. The preferred material option is plastic. If there is no structure designed with a jig to allow it to deform and a fixture for assembly and disassembly, it is difficult to restore the plastic to its original state after disassembly, and it can only be destructively disassembled and replaced with new parts. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a guide rail and a sunshade device with a labor-saving lever to improve the convenience of installation and disassembly of the guide rail of the sunshade device.

[0004] The first aspect of the embodiment of the present application provides a guide rail with a labor-saving lever, including: a guide rail body, including an arc notch, an inner plate, a first limiting portion, a second limiting portion, a third limiting portion, a first flange, and a first groove, the arc notch is arranged on one side of the inner plate, the first limiting portion is arranged on the other side of the inner plate, the second limiting portion is arranged on the left side of the inner plate, the third limiting portion is arranged on the inner plate, and the first groove is arranged on the right side of the inner plate; the guide rail cover includes an arc flange, a fourth limiting portion, a fifth limiting portion, a sixth limiting portion, a female buckle, and a second groove; the arc flange is placed in the arc notch, the first flange is connected to the female buckle, the first limiting portion and the fourth limiting portion form a limiting groove with an open end to limit the movement direction of the bottom rail part, the second limiting portion composed of the second flange, the third flange and the bottom plate is used to connect the first angle code, the third limiting portion composed of the second limiting portion, the fourth flange, the fifth flange and the inner plate is used to connect the second angle code, and the first groove and the second groove are used to connect the sealing strip.

[0005] In one implementation, the surfaces of the arc groove and the arc flange are composed of several segments of tangent arc surfaces, the arc groove and the arc flange are coaxial, and after the arc flange is connected to the arc groove, the installation and removal of the guide rail cover can only move along the radial direction of the arc groove.

[0006] In this implementation, the arc groove limits the four directions of linear motion of the guide rail cover and prevents it from moving, which plays a good limiting role and also provides a rotation fulcrum for the lever-saving force arm.

[0007] In one implementation, a sixth flange is provided on the extended geometry of the arc groove, and a sixth limit portion is provided on the guide rail cover. These features are used to ensure the parallelism and positioning of the first limit portion and the fourth limit portion of the guide rail after assembly is completed, and prevent the guide rail cover from moving inwardly of the guide rail body.

[0008] In one implementation, the distance from the female buckle of the guide rail cover to the arc flange is smaller than the distance from the front plate of the guide rail cover to the arc flange. Since the guide rail cover can only rotate along the axis of the arc notch during installation and removal, the axis is regarded as a fulcrum, the force generated by the engagement and disengagement of the female buckle and the first flange is the resistance, the distance from the female buckle to the arc flange is the resistance arm, the distance from the front plate to the arc flange is the power arm, and the force applied to the front plate for installation or removal is the power. According to the lever principle, the power arm is longer than the resistance arm, which is a labor-saving lever, so the guide rail cover can be installed or removed with less force.

[0009] In one implementation, the material thickness of the cantilever beam of the female buckle is thinner than the overall material thickness of the sleeve and the guide rail cover, which is conducive to the precise control of the tolerance of aluminum extrusion molding and ensures that the female buckle can be elastically deformed during assembly and can be restored to its original position after assembly. After the sleeve is buckled with the first flange, it forms a lock and provides a holding force to prevent the guide rail cover from radially detaching. The pouring surface of the female buckle is an inclined surface. When the guide rail cover is rotated and buckled, the second pouring surface of the first flange of the guide rail body contacts the pouring surface of the female buckle and causes the cantilever beam to be elastically deformed, thereby locking the guide rail cover.

[0010] In a further embodiment, the retaining surface of the sleeve may have a taper, and the corresponding mating surface with the first flange may also have a taper, so that the female buckle can be smoothly separated from the first flange when subjected to a large separation force.

[0011] In a second aspect, the present application provides a sunshade device including a guide rail with a labor-saving lever provided by any of the above implementations. The guide rail is used for supporting and connecting corner code parts in the sunshade device, and is also used for connecting with a guide groove.

[0012] The sunshade device provided by the present application uses a roller blind guide rail provided by the present application for disassembly and assembly by a labor-saving lever, which has at least the following beneficial effects: the arc flange of the guide rail cover is connected to the arc groove of the guide rail body, the contour of the arc flange is coaxial with the contour of the arc groove, the arc groove plays the role of limiting, positioning and lever fulcrum for the guide rail cover body, the guide rail cover only needs to be provided with a buckle to constrain itself to move radially along the arc groove, and the disassembly and installation of the guide rail cover body are both labor-saving lever designs. The material thickness of the cantilever beam of the buckle is thinner than the material thickness of the sleeve and the guide rail body, so that it can be deformed and restored to its original position during assembly, thereby achieving the purpose of labor-saving assembly and disassembly.

[0013] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1 to Figure 6 The present application provides a guide rail with a labor-saving lever type disassembly and assembly, including a guide rail body 8 and a guide rail cover 9. The guide rail body 8 includes an arc notch 11, an inner plate 12, a first position-limiting portion 13, a second position-limiting portion 14, a third position-limiting portion 15, a first flange 20, and a first groove 16. The arc notch 11 is arranged on one side of the inner plate 12, the first position-limiting portion 13 is arranged on the other side of the inner plate 12, the second position-limiting portion 14 is arranged on the left side of the inner plate 12, the third position-limiting portion 15 is arranged on the inner plate 12, and the first groove 16 is arranged on the right side of the inner plate 12.

[0028] The guide rail cover 9 includes an arc flange 30, a fourth limiting portion 31, a fifth limiting portion 32, a sixth limiting portion 33, a female buckle 34, and a second groove 35; the arc flange 30 is placed in the arc notch 11, the first flange 20 is buckled with the female buckle 34, the first limiting portion 13 and the fourth limiting portion 31 are surrounded by a first limiting groove 90 with a wide opening at one end and a second limiting groove 130 with a narrow opening, the second limiting groove is provided with a fifth limiting portion 32 for auxiliary limiting, and the bottom rail 50 is in the first limiting groove. The first limiting groove 16 and the second limiting groove 130 are used to place the roller blind and the zipper guide 131. The second limiting portion 14 composed of the second flange 110, the third flange 111 and the bottom plate 112 is used to place the first angle code 101. The third limiting portion 15 composed of the second limiting portion 14, the fourth flange 120, the fifth flange 121 and the inner plate 12 is used to place the second angle code 102. The first groove 16 and the second groove 35 can be used to place the sealing strip 103.

[0029] The side of the bottom rail 50 is placed in the limiting groove 90, and the two side surfaces of the bottom rail 50 are limited by the limiting groove 90, so as to prevent the bottom rail 50 from shaking freely in the limiting groove 90. The second limiting portion 14 provided on the guide rail body 8 is used to locate and connect the first angle code 101, and the third limiting portion 15 is used to locate and install the second angle code 102. The arc flange 30 of the guide rail cover 9 is assembled with the arc notch 11 of the guide rail body 8, and then the female buckle 34 of the guide rail cover 9 is buckled and locked with the first flange 20 of the guide rail body 8. Wherein:

[0030] The arc groove 11 limits the freedom of movement of the arc flange 30, so that the guide rail cover 9 including the arc flange 30 can only rotate along the contour center axis of the arc groove 11. A group of buckles 34 are arranged in the direction of its rotation to lock the guide rail body 8 and the guide rail cover 9. The position of the buckles 34 conforms to the principle of labor-saving levers, thereby achieving the purpose of labor-saving disassembly and installation.

[0031] The present application provides a sunshade device, including the guide rail provided above, the guide rail is used to connect the first corner code 101, the second corner code 102 and the zipper guide rail 131, and is also used to constrain the freedom of movement of the bottom rail 50. The sunshade device of the present application is a sunshade device with a rotation function and used to roll up a covering object, such as a roller blind, a ceiling blind, etc.

[0032] In a possible implementation, the shapes of the first angle bracket 101, the second angle bracket 102, the bottom rail 50, and the zipper guide rail 131 are not defined herein, and only the positions and constraints of their connection with the guide rails are described. For example, Figure 1 and Figure 2The figure shows the assembly intention and shape of part of the first angle code 101 and the second angle code 102. The first angle code 101 and the second angle code 102 can also be put into the mold cavity of the guide rail (the mold cavity of the guide rail refers to the combination of the first limiting part 14 and the second limiting part 15 and any shape in the area where they are located). The mold cavity of the guide rail is used to locate and constrain the first angle code 101 and the second angle code 102. The shapes of the first angle code 101 and the second angle code 102 can also be arbitrarily combined. The surface 200 of the guide rail plays a role in supporting the first angle code 101 and the second angle code 102.

[0033] The shapes of the bottom rail 50 and the zipper guide rail 131 are not defined here, and only their positions and connection relationships on the guide rails are described. Figure 1 In the direction description, exemplarily, the upper and lower directions of the zipper guide rail 131 are limited and constrained by the second limiting groove 130 and the fifth limiting portion 32, and the upper and lower directions of the bottom rail 50 are limited and constrained by the limiting groove 90.

[0034] In a possible implementation, the surfaces of the arc notch 11 and the arc flange 30 are composed of several tangent arc surfaces, the contour center of the arc notch 11 is coaxial with the contour center of the arc flange 30, and after the arc flange 30 is connected to the arc notch 11, the installation and removal of the guide rail cover 9 can only move along the radial direction of the arc notch 11, that is, the arc flange 30 can only move in the tangent direction of the arc surface of the arc notch 11. The upward, downward, leftward and rightward position movement of the guide rail cover 9 is also restricted, and the arc notch 11 plays a good limiting role.

[0035] The extended geometric body of the arc notch 11 is provided with a sixth flange 60, and the guide rail cover 9 is provided with a sixth limit portion 33. These features ensure the parallelism of the first limit portion 13 and the fourth limit portion 31 of the guide rail after assembly, so that the first limit portion 13 and the fourth limit portion are parallel or nearly parallel, preventing the guide rail cover 9 from rotating toward the inner side of the guide rail body 8 (such as Figure 1 The direction of rotation is counterclockwise as indicated by the arrow 600 marked in the figure).

[0036] In a possible implementation, the sixth limiting portion 33 of the guide rail cover 9 and the sixth flange 60 of the guide rail body 8 simultaneously play a limiting role, and the number thereof can be zero, one, or even more than one. In this embodiment, the sixth limiting portion 33 and the sixth flange 60 can exist at the same time, or only one can exist alone, that is, they cannot be zero at the same time, but can be multiple at the same time. The main purpose is to prevent the guide rail cover 9 from rotating toward the inner side of the guide rail body 8. In this embodiment, the positions of the sixth limiting portion 33 and the sixth flange 60 are not limited, as long as they can simultaneously generate mutual forces at the positions of the guide rail cover 9 and the guide rail body 8, and are used to prevent the guide rail cover 9 from rotating toward the inner side of the guide rail body 8.

[0037] See also Figure 3 The center line 300 in the figure is the center line of the width center from the outermost edge of the arc edge 30 of the guide rail cover to the outermost edge of the outer side of the second groove 35. This line is a virtual line segment and is only used to understand the orientation or position relationship shown in the figure. Therefore, it cannot be understood as a limitation to the present application.

[0038] In a possible implementation, the distance from the female buckle 34 of the guide rail cover 9 to the central axis of the contour of the arc flange 11 is smaller than the distance from the front plate 80 of the guide rail cover 9 to the central axis of the contour of the arc flange 11, and the distance from the female buckle 34 to the center line 300 is smaller than the distance from the front plate 80 to the center line 300. Since the guide rail cover 9 can only rotate along the central axis of the contour of the arc slot 11 during installation and removal, according to the lever principle, the central axis of the arc slot 11 is regarded as the rotation fulcrum of the force-saving lever, the distance from the female buckle 34 to the center of the contour of the arc flange 11 is the resistance arm, the distance from the front plate 80 to the center of the contour of the arc flange 11 is the power arm, the force generated by the fastening and disengagement of the female buckle 34 and the first flange 20 is the resistance, and the force applied to the front plate 80 during installation and removal is the force generated (such as Figure 1 The direction of rotation of the arrow 600 marked in the figure includes clockwise and counterclockwise forces) is the power, and the power arm is longer than the resistance arm to form a labor-saving lever, so the guide rail cover body 9 can be installed or removed by applying less force.

[0039] In a possible embodiment, the cantilever beam 90 of the female buckle 34 is a deflection element, and the material thickness of the cantilever beam 90 is thinner than the overall material thickness of the sleeve 91 and the guide rail cover 9, so that when the female buckle 34 is connected to the first flange 20, the cantilever beam 90 can be elastically deformed and can be restored to the original position after assembly. After the sleeve 91 is buckled with the first flange 20, it forms a lock and provides a holding force to prevent the guide rail cover 9 from radially detaching. The pouring surface 92 is an inclined surface. When the guide rail cover 9 is rotated and buckled, the second pouring surface 93 of the first flange 20 of the guide rail body 8 contacts the pouring surface 92 of the female buckle 34 and causes the cantilever beam 90 to be elastically deformed, buckled and restored, thereby locking the guide rail cover 9.

[0040] See also Figure 1 In a possible implementation, the retaining surface 140 of the sleeve 91 has a taper, and the corresponding mating surface 141 of the first flange 20 also has a taper, so that the female buckle 34 can be smoothly separated from the first flange 20 when subjected to a large separation force.

[0041] See also Figure 3-Figure 5 The fifth limiting portion 32 can be composed of various shapes. For example, Figure 3-Figure 5 3A and 3B respectively show three forms of the fifth limiting portion 32 , all of which are used to limit the zipper guide rail 131 .

[0042] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
