Description

Technical Field

[0001] The utility model belongs to the technical field of louver canopies, and relates to an installation structure of louver blades of a louver canopy. Background Art

[0002] A louver canopy is a relatively common sunshade tool in modern life. For example, a louver canopy disclosed in a Chinese patent (publication number: CN110886533A) includes a canopy frame and a group of louver blades. The canopy frame includes at least two louver canopy beams and at least two columns. A transmission mechanism is provided on the columns, and a flipping device is provided on the louver canopy beams. The transmission mechanism controls the flipping device to flip through a linkage member, and can enable the group of louver blades to flip.

[0003] It can be known from the original text recorded in paragraph

[0027] of the specification of the comparative document that the group of louver blades of this louver canopy is cooperated by a flipping gear and a linkage chain in the flipping mechanism. The flipping gear drives the flipping pin to rotate. And it is clearly stated in the original text recorded in paragraph

[0029] of the specification of the comparative document that the flipping pin includes a pin shaft and a louver card seat. The pin shaft is used for fixed cooperation with the flipping gear. The louver card seat is clamped with the louver blades through two formed card slots. After the flipping pin is limited by the mounting seat, each louver blade can be firmly installed and can be flipped open or closed.

[0004] In the actual use process, since the louver canopy is generally installed outdoors, after long-term use, the louver blades will be damaged to varying degrees due to external factors. Therefore, users need to periodically check it and timely replace the damaged louvers.

[0005] For the above structure, the user needs to first remove the mounting seat, and then remove the louver blade to be replaced together with the flipping pin at one end or both ends thereof. However, since the flipping gear is fixed on the pin shaft of the flipping pin, the flipping gear also needs to be removed together. This causes that in addition to the louver blade that needs to be removed, some structures of the flipping device for controlling the transmission also need to be removed. When installing a new louver blade later, in addition to paying attention to whether the installation position of the louver blade is correct, it is also necessary to check whether the installation cooperation of the flipping gear and the linkage chain is in place, and the operation is very inconvenient. Summary of the Invention

[0006] The purpose of the utility model is to propose an installation structure of louver blades of a louver canopy for the existing technologies with the above problems. The technical problem to be solved by the utility model is: how to improve the convenience of replacing the louver blades.

[0007] The object of the present utility model can be achieved by the following technical solutions: A mounting structure for the louver blades of a louver awning. The louver awning includes an awning frame, and a hinge plate is rotatably connected inside the awning frame. It is characterized in that the mounting structure includes a positioning piece and a fastener. The hinge plate has a connecting portion that abuts against one side surface of the louver blade. The positioning piece is located on the other side surface of the louver blade. The positioning piece and the connecting portion are detachably connected by the fastener and clamp the end of the louver blade.

[0008] In the mounting structure of the louver blades of this louver awning, the louver blades are mounted by clamping them with a positioning piece and the connecting portion of the hinge plate in cooperation with a fastener. Specifically, the awning frame includes a square frame and support legs fixed at the circumferential corners of its bottom. Specifically, in this louver awning, a motor serving as a driving source is provided inside the support legs of the awning frame, and linkage rods are arranged horizontally on the opposite side walls on both sides inside the frame of the awning frame. A number of hinge plates are arranged on both sides inside the frame, and at least one hinge plate is connected to the motor through a driving linkage assembly, and the remaining hinge plates are hinged on the linkage rods. When the motor is working, it can drive at least one hinge plate to rotate through the driving linkage assembly, and this hinge plate drives the remaining hinge plates to rotate together through the linkage rods. That is to say, through the setting of the mounting structure in this case, two hinge plates corresponding in position can drive a louver blade to open and close, and through the cooperation of the linkage rods, a number of louver blades can be linked to open and close synchronously. On the basis of the above structure, in the mounting structure of the louver blades of this louver awning, each hinge plate includes a connecting portion. One side surface of the end of the louver blade abuts against the connecting portion, and the connecting portion supports one side surface of the end of the louver blade. Secondly, a positioning piece is installed on the other side surface of the end of the louver blade, and while using a fastener to connect and lock the positioning piece and the connecting portion of the hinge plate, the end of the louver blade is clamped by the cooperation of the connecting portion and the positioning piece, so that the end of the louver blade is firmly positioned. When the louver blade is damaged and needs to be replaced, the fastener, as the main positioning component, only needs to be removed, and the positioning piece and the louver blade to be replaced can be removed from the frame of the awning frame together, and the hinge plate used for driving and other driving components do not need to be disassembled from the awning frame together with the louver blade, and subsequently, only the corresponding new louver blade and positioning piece need to be installed and locked with screws, ensuring that the disassembly and replacement of the damaged louver blade are more convenient.

[0009] In the installation structure of the louver blades of the above-mentioned louver awning, the connecting portion and the positioning piece are strip-shaped and arranged along the width direction of the louver blade. One end of the positioning piece is continuously bent along the length direction to form a positioning portion. A first relief hole is provided on the louver blade. A connecting hole is provided at one end of the connecting portion. The positioning portion passes through the first relief hole and the connecting hole and is clamped with the end of the connecting portion having the connecting hole. As a specific solution, the positioning portion at one end of the positioning piece passes through the first relief hole of the louver blade and the connecting hole on the connecting portion in an insertion manner, and is clamped by its own continuous bending structure and the end of the connecting portion having the connecting hole, so as to ensure that the positioning piece can be firmly positioned even when the fastener is not installed, and further ensure that the subsequent installation of the fastener is more convenient.

[0010] In the installation structure of the louver blades of the above-mentioned louver awning, the positioning piece further has an abutting portion adjacent to the positioning portion. The abutting portion is bent towards the connecting portion and abuts against the surface of the louver blade facing the positioning piece. While being clamped by the positioning portion and the connecting portion, the abutting portion can also abut against the outer wall of the louver blade, thereby ensuring higher pre-positioning stability of the positioning piece.

[0011] In the installation structure of the louver blades of the above-mentioned louver awning, an oval hole is provided at the other end of the positioning piece. A second relief hole is provided on the louver blade. A fixing hole is provided at the other end of the connecting portion. The fastener sequentially passes through the oval hole and the second relief hole and is screwed and locked with the fixing hole. Thus, the louver blade is clamped by screwing the fastener with the positioning piece and the connecting portion, ensuring the firm installation of the louver blade, and due to the setting of the oval hole, ensuring higher installation adaptability of the positioning piece.

[0012] In the installation structure of the louver blades of the above-mentioned louver awning, a convex arched portion is formed on the middle part of the positioning piece facing away from the connecting portion, and there is a gap between the arched portion and the surface of the louver blade. On the premise of ensuring the firm installation of the positioning piece, the contact amount between the positioning piece and the louver blade is reduced, the sliding friction between the louver blade and the positioning piece during rotation is reduced, and the wear amount of the two is effectively controlled.

[0013] Compared with the prior art, the installation structure of the louver blades of this louver awning has the following advantages:

[0014] The side surface of the louver blade is supported by the connecting portion of the hinge plate, and the other side surface of the louver blade is pressed by the positioning piece. The positioning piece and the connecting portion are pre-fixed by clamping through the cooperation of the positioning portion and the connecting hole, and are screwed and locked by the cooperation of the fastener and the fixing hole, so as to clamp the louver blade, ensuring firm connection of the louver blade and being more convenient for later disassembly and replacement.

Specific embodiments

[0022] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0023] As Figure 1 shown in combination with Figure 2 In the louver blade mounting structure of the present louver awning, the louver awning includes an awning frame 1. Specifically, the awning frame 1 includes a horizontally arranged frame and support legs fixed to the circumferential corners of the lower side surface of the awning frame 1. A plurality of hinge plates 2 are provided on two opposite side walls in the frame of the awning frame 1, and the positions of the plurality of hinge plates 2 on both sides are in one-to-one correspondence, so that every two hinge plates 2 with corresponding positions form a group.

[0024] Combined with Figures 4 - 6, each hinge plate 2 is provided with a strip-shaped connecting portion 21 arranged along the width direction of the louver 3. The lower side surface of the end of the louver 3 abuts against the connecting portion 21. The installation structure includes positioning pieces 4 with a quantity equal to that of the hinge plates 2. Each positioning piece 4 is strip-shaped and arranged along the width direction of the louver 3, and the positioning piece 4 is located on the upper side surface of the end of the louver 3. On the plate surface of the louver 3 near the end, a first relief hole 31 and a second relief hole 32 are arranged at intervals along the width direction. The first relief hole 31 is square, and the second relief hole 32 is circular. One end of the connecting portion 21 is provided with a connecting hole 211 that is aligned with the first relief hole 31 and has a square shape. The other end of the connecting portion 21 is provided with a fixing hole 212 that is aligned with the second relief hole 32 and has a circular shape.

[0025] Combined Figure 3 , one end of the positioning piece 4 is continuously bent to form a positioning portion 41, and an abutting portion 42 adjacent to the positioning portion 41 is also bent at this end of the positioning piece 4. When installing the louver 3, the user places the end of the louver 3 on the connecting portion 21 of the hinge plate 2, aligns the first relief hole 31 with the connecting hole 211, and aligns the second relief hole 32 with the fixing hole 212. At this time, the user can place the positioning piece 4 on the louver 3 so that the positioning portion 41 passes through the first relief hole 31 and the connecting hole 211 in sequence. On the premise that the abutting portion 42 abuts against the upper side surface of the louver 3, the positioning portion 41 is clamped with the side of the connecting portion 21 facing away from the louver 3, thereby completing the preliminary positioning of the louver 3.

[0026] A kidney-shaped hole 43 is formed along the length direction at the other end of the positioning piece 4. The position of the kidney-shaped hole 43 is opposite to the relief hole. The installation structure further includes a fastener 5, which is specifically a screw. The fastener 5 passes through the kidney-shaped hole 43, the second relief hole 32 in sequence and is screwed with the fixing hole 212, so that the positioning piece 4 and the connecting portion 21 clamp the end of the louver 3. It is worth mentioning that by setting the hole formed on the positioning piece 4 as the kidney-shaped hole 43, the requirement for the installation accuracy of the positioning piece 4 is reduced as much as possible, and the situation where the fastener 5 cannot be installed due to misalignment of the hole positions is avoided.

[0027] In addition, as Figure 3 shown, a protruding arch portion 44 is formed at the middle part of the positioning piece 4 relative to the upper side plate surface of the louver 3. In this way, when the positioning piece 4 is installed and maintained in a positioned state, a gap 6 is formed between the arch portion 44 and the upper side plate surface of the louver 3. The formation of this gap 6 can reduce the overall contact amount between the positioning piece 4 and the upper side plate surface of the louver 3, reduce the sliding friction formed between the middle part of the louver 3 and the positioning piece 4 during the rotation process of the louver 3, and further reduce the wear amount generated by the two.
