DETAILED DESCRIPTION

[0030] Reference Figure 1-12As shown, a connection structure between a louver 1 and an end cover 2 comprises a louver 1 and an end cover 2, wherein the end cover 2 is arranged in parallel on both sides of the louver 1, and a plurality of groups of fixing members 3 are arranged on the louver 1 and at both ends, and a gap 4 is formed between the fixing members 3 and the louver 1, and a notch 5 matching the fixing members 3 is arranged on the end cover 2, and the end cover 2 is translated toward the louver 1 so that the fixing members 3 are embedded in the notch 5, thereby clamping the end cover 2 on the louver 1.

[0031] Among them, reference Figure 4 As shown, the louver 1 is in a continuous right-angle bend shape. Specifically, a first groove 6 and a second groove 7 are formed on the upper surface of the louver 1 by bending, and a third groove 8 and a fourth groove 9 are formed on the lower surface of the louver 1. Mounting holes for mounting the fixing member 3 are provided on the bottom edges of the first groove 6, the second groove 7 and the fourth groove 9, and the fixing member 3 is arranged at the first groove 6, the second groove 7 and the fourth groove 9.

[0032] like Figure 5 As shown, it is a matching structure diagram of the louver 1 and the fixing part 3. The fixing part 3 has been installed on the louver 1 through the mounting hole. The fixing part 3 is a step rivet, including a fixing part 31 and a step part 32. As shown in the figure, the step part 32 and the fixing part 31 are the two ends of the step rivet, wherein the fixing part 31 is located on the upper surface of the louver 1, and the gap 4 is the distance from the upper surface of the step part 32 to the lower surface of the louver 1.

[0033] refer to Figure 6-7 As shown, it is a structural stereogram of the end cover 2. The overall appearance of the end cover 2 is an eccentric "convex" shape. The end cover 2 is composed of a convex portion 22 in the upper part and a base 21 in the lower part. The convex portion 22 is not located at the center of the base 21 and can match the shape of the louver 1. When matched, the upper surface of the convex portion 22 is attached to the lower bottom surface of the fourth groove 9, and the upper surfaces of the base 21 and located on both sides of the convex portion 22 are respectively attached to the lower bottom surfaces of the first groove 6 and the second groove 7.

[0034] Only one group of slots 5 are provided on the upper surface of the protrusion 22 and the two side surfaces of the base 21, and the slots 5 are opposite to the direction of the louver 1. The slots 5 include an upper slot 51 and a lower slot 52 that are connected, wherein the upper slot 51 is through-through on the top surface. Specifically, the upper slot 51 is a proportionally reduced shape of the lower slot 52, and the depth and width of the upper slot 51 are both smaller than those of the lower slot 52. When matched, the step portion 32 is located at the lower slot 52, and the gap 4 is located at the upper slot 51. Since the width of the step portion 32 is greater than that of the upper slot 51, it is ensured that the step portion 32 can be clamped in the lower slot 52 without longitudinal movement.

[0035] In order to further ensure that the end cover 2 will not separate from the louver 1, a locking hole 10 is provided on the top surface of the protrusion 22 on the end cover 2 and next to the notch 5. At the same time, a through hole 11 matching the locking hole 10 is provided at the matching position of the bottom surface of the fourth groove 9 of the louver 1. When the end cover 2 and the louver 1 are matched to the louver 1, self-tapping screws 12 are provided to pass through the through holes 11 from top to bottom in sequence and screwed into the locking holes 10, thereby further ensuring the movement of the end cover 2 in the axial direction of the louver 1 and completing the locking.

[0036] Combination Figure 3 and Fig.11 As shown, a through hole 15 is provided at the center of the outer side surface of the protrusion 22 (the opposite side of the louver 1), and the through hole 15 consists of two sections, including a round hole 151 and a waisted round hole 152. The round hole 151 is located on the side close to the louver 1, and the waisted round hole 152 is located on the outside. The aperture of the waisted round hole 152 is smaller than the aperture of the round hole 151. A rivet shaft 16 with a waisted round end is provided at one end and embedded in the waisted round hole 152 from the outside. In addition, a round head screw 17 is provided and embedded in the round hole 151 from the direction of the louver 1. A deep hole matching the round head screw 17 is provided on the side of the rivet shaft 16 with the waisted round end. The round head screw 17 is screwed into the deep hole on the rivet shaft 16. At the same time, it is restricted by the round hole 151 and the round head screw 17 cannot move forward, so the rivet shaft 16 is fixed at the waisted round hole 152.

[0037] The purpose of providing the waist-round hole 152 to cooperate with the riveting shaft 16 with a waist-round end is to prevent the riveting shaft 16 from rotating autonomously.

[0038] In order to achieve the reversal of the shutter 1, a connecting hole 13 is provided at the end of the base 21 and at the matching position of the lower end of the first groove 6, a recessed portion 18 is provided on the inner side of the connecting hole 13, and a protruding portion 19 is provided on the outer side, and a transverse rod 14 is provided on the side of the base 21 relative to the shutter 1, and the top surface height of the transverse rod 14 is lower than the top surface height of the base 21, and the continuously arranged end covers 2 are all rotatably arranged on the transverse rod 14, so that the shutters 1 can be controlled to rotate synchronously when the transverse rod 14 is pulled.

[0039] Part of the protrusion 19 is higher than the surface of the base 21, and the recessed portion 18 is only recessed in the connecting hole 13. The protruding area of ​​the protrusion 19 is much smaller than the side area of ​​the base 21. A fastening nail 20 is provided to pass through the connecting hole 13 from the direction of the recessed portion 18 and pass out from the protrusion 19. In order to ensure that the end cover 2 can be rotated at a fixed position on the end cover 2, the fastening nail 20 includes a smooth area 202 located on the screw body and a threaded area 201 at the bottom. The smooth area 202 is located at the connecting hole 13, and the threaded area 201 protrudes from the direction of the protrusion 19 to the outside of the base 21. The end cover 2 is fixed on the transverse rod 14 by the threaded area 201. At the same time, the end cover 2 can be rotated on the transverse rod 14 through the smooth cooperation between the smooth area 202 and the connecting hole 13.

[0040] References Fig.12 As shown, in order to further prevent the fixing member 3 from falling off, a convex clamping edge 22 is provided at the middle of the upper notch 51. Since the end cover 2 is made of plastic, when the gap 4 on the fixing member 3 is inserted into the upper notch 51, the fixing member 3 is clamped into the upper notch 51 through the principle of plastic deformation, and the fixing member 3 is restrained to a certain extent through the convex clamping edge 22, thereby achieving an anti-falling effect.

[0041] At the same time, a mesh reinforcement rib 21 is provided on the protrusion 22 and on one side of the riveting shaft 16, which saves processing materials while ensuring the strength of the component. At the same time, the part of the base 21 on one side of the connecting hole 13 is vacant, and this part is an omittable part, which can greatly avoid waste of materials.

[0042] References Figure 2 As shown, in order to ensure that the shutter 1 can be installed on the awning and can ensure that the shutter 1 can be turned synchronously, the turning riveted shafts 16 on the end covers 2 on both sides of the shutter 1 are respectively installed in a fixed turning sleeve.

[0043] Furthermore, the shutters 1 at both ends of the awning are fixed and cannot be flipped, but it is still necessary to fix the shutters 1 on the awning by setting the flip riveting shaft 16. In order to ensure that the shutters 1 will not flip synchronously due to the movement of the transverse rod 14, bolts are not set on the connecting holes 13 on the shutters 1 here. When the transverse rod 14 moves, it will not drive the shutters 1 at the end to flip. At the same time, a round hole is set on the other side of the end cover 2, and a fixing nail is set to fix the end cover 2 to the awning frame.

[0044] Working process of the utility model: in actual installation operation, the fixing part 3 is directly riveted at the mounting hole position on the louver 1, the integral end cover 2, wherein the riveting shaft 16 is embedded in the waist circular hole 152, and the other end is cooperated with the round head screw 17 located in the circular hole 151 to fix the riveting shaft 16 on the convex part 22, hold the end cover 2, align the convex part 22 with the fourth groove 9, and move horizontally to move the side with the notch 5 toward the direction of the louver 1, and the fastener is gradually embedded in the notch 5. At this time, the step part 32 is located at the lower notch 52, and the gap 4 is located at the upper notch 51. By continuing to press, the gap 4 passes through the convex clamping edge 22 and abuts against the deepest part of the notch 5. At this time, the through hole 11 and the locking hole 10 are overlapped, and the self-tapping screw 12 is driven into the locking hole 10 from top to bottom to complete the locking.

[0045] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
