[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0027] like Figures 1 to 5 As shown in the figure, this utility model embodiment discloses a connector, including a fixing seat 1, a fixing rod 2 and a blade fixing plate 3. The front end face of the fixing seat 1 forms a first through hole 11 through the rear end face. A bushing 4 is sleeved on the outer periphery of the fixing rod 2. The fixing rod 2 and the bushing 4 are both inserted into the first through hole 11. A limiting step 31 is provided on the side of the blade fixing plate 3 away from the fixing seat 1. One end of the fixing rod 2 is embedded in the limiting step 31.

[0028] In contrast to existing installation methods that use screws to fix the blade profile to the connector, this embodiment provides a limiting step 31 on the blade fixing plate 3. Then, the fixing rod 2, which is assembled on the fixing seat 1, is embedded in the limiting step 31. The blade fixing plate 3 is fixedly connected to the end of the blade profile. In the prior art, the blade fixing plate 3 and the blade profile are generally fixed with screws. In this way, the fixing rod 2 is fixedly connected to the blade through the limiting step 31. The fixing seat 1 is not fixed to the blade with screws. For the installation scenario of ultra-large louver sections, compared with the problem of breakage and instability that may occur with screw installation, the connection between one end of the fixing rod 2 and the limiting step 31 is more secure and reliable, which increases the service life of the product and reduces the probability of damage to parts and blades.

[0029] Furthermore, in this embodiment, a bushing 4 is provided on the outer periphery of the fixing rod 2, so that the bushing 4 and the fixing rod 2 are assembled together in the first through hole 11, similar to the bearing installation principle. This can increase the load-bearing capacity of the fixing rod 2, withstand greater force and torque, improve stability and reliability, reduce wear on the fixing rod 2, and extend its service life.

[0030] Furthermore, the blade fixing plate 3 is provided with a rotating hole for accommodating the fixing rod 2, and the rotating hole is connected to the limiting step 31, which is a hollow structure.

[0031] Furthermore, the upper side of the fixed base 1 is provided with a positioning hole 12, which communicates with the first through hole 11. A fastener is installed in the positioning hole 12, and the fastener abuts against the outer wall of the bushing 4. The bushing 4 is limited and fixed in the first through hole 11 by the positioning hole 12 and the fastener, preventing the bushing 4 from sliding out of the fixed base 1, thereby improving the structural stability. The bushing 4 and the fixed base 1 constitute an oil-free self-lubricating bearing structure.

[0032] In some embodiments, the limiting step 31 is snapped into the blade, the blade fixing plate 3 is provided with a plurality of first fixing holes 32, and the end of the blade is provided with an installation port for receiving the limiting step 31 to be snapped into place and a second fixing hole corresponding to the first fixing hole 32.

[0033] Screws are generally used to fix the first fixing hole 32 and the second fixing hole. The limiting step 31 is connected to the end of the blade profile by snap-fit. In this way, the blade fixing plate 3 is installed through the original screw holes and the snap-fit ​​of the limiting step 31, which improves the reliability and stability of the fixed connection between the blade fixing plate 3 and the blade profile. This makes the installation more secure and reliable when the fixing rod 2 is fixedly connected to the blade profile through the limiting step 31.

[0034] In some embodiments, the bushing 4 is made of copper-based alloy, and the fixing seat 1 and fixing rod 2 are made of stainless steel.

[0035] Stainless steel is characterized by its high strength and hardness. When used for connecting louver blades, it offers advantages over plastic connectors on the market, such as resistance to aging, longer service life, ability to withstand stress in large areas, and good load-bearing capacity. It also has strong wind resistance, reducing the probability of damage to parts and blades, and making installation more secure and reliable.

[0036] Furthermore, the length of the bushing 4 is greater than or equal to the depth of the first through hole 11.

[0037] In some embodiments, a limiting member 5 is also provided, and a positioning groove 21 is provided on the outer periphery of the other end of the fixing rod 2. The limiting member 5 is connected to the positioning groove 21, and the limiting member 5 is used to prevent the other end of the fixing rod 2 from detaching from the first through hole 11.

[0038] The positioning groove 21 is formed by the outer wall of the fixing rod 2 being recessed towards the central axis. It is generally an annular groove. Of course, multiple positioning grooves 21 can also be designed on the outer periphery of one end of the fixing rod 2. The multiple positioning grooves 21 are arranged around each other. Correspondingly, the limiting member 5 has a fixing block 51 that is adapted to the positioning groove 21. The limiting member 5 is embedded in the positioning groove 21, which can prevent the fixing rod 2 from sliding out or loosening from the front side to the rear side of the fixing seat 1.

[0039] During assembly, the bushing 4 is pre-assembled with the fixing rod 2, and then inserted together from the rear side of the fixing seat 1 until the other end of the fixing rod 2 passes through the first through hole 11. The fastener is driven into the positioning hole 12 and abuts against the outer wall of the bushing 4, so that the bushing 4 is fastened in the fixing seat 1. The limiting part 5 is snapped into the positioning groove to realize the assembly of the fixing rod 2 and the fixing seat 1.

[0040] Furthermore, a fixing block 51 is provided on the inner side of the limiting member 5 along the circumferential direction. The fixing block 51 is embedded in the positioning groove 21, and an opening 52 is left on one side of the limiting member 5. During installation, the limiting member 5 can be pushed to contact the outer peripheral wall of the fixing rod 2 through the opening 52 of the limiting member 5, so that the fixing block 51 is embedded in the positioning groove 21; or the limiting member 5 can be inserted from the other end of the fixing rod 2 until the fixing block 51 is embedded in the positioning groove 21.

[0041] Typically, a fixing block 51 is provided on the upper, lower and right sides of the inner side of the limiting member 5, and the opening 52 is located on the left side, so that the limiting member 5 is engaged with the positioning groove 21 through the fixing block 51, preventing the fixing rod 2 from sliding out or falling off from the first through hole 11, and ensuring the reliability and stability of the connecting member.

[0042] In some embodiments, a positioning block 6 is provided at one end of the fixing rod 2. The cross-section of the positioning block 6 is larger than the cross-section of the first through hole 11. The positioning block 6 is located between the blade fixing plate 3 and the fixing seat 1.

[0043] The fixing rod 2 is confined in the first through hole 11 of the fixing base 1 by the limiting member 5 and the positioning block 6, so as to prevent the fixing rod 2 from sliding out or falling off from the first through hole 11. The positioning block 6 can be designed as a square, a cylinder, etc., as long as the cross-section of the positioning block 6 is larger than the cross-section of the first through hole 11.

[0044] In some embodiments, the upper end face of the fixing base 1 extends through the lower end face to form a second through hole 13, and a locking member 7 is assembled in the second through hole 13. The locking member 7 is a long bolt, and the central axis of the second through hole 13 is perpendicular to the central axis of the first through hole 11. Furthermore, the second through hole 13 and the positioning hole 12 have the same depth direction.

[0045] Compared to existing connectors that are directly fixed to the inner wall of the crossbeam with screws and lack radial fixation, this implementation is suitable for installing louvers on the top of a pavilion. The crossbeam serves as the main fixed component of the pavilion's top. The fixing seat 1 is fixedly connected to the crossbeam via the second through hole 13 and the locking component 7, thus determining the installation position of the fixing seat 1 and providing downward support. During the rotation of the blade profile around the central axis of the fixing rod 2 via the rotating structure, the fixing seat 1 does not easily shift or slide, and the central axis of the fixing rod 2 is not easily changed, improving the overall stability and reliability of the structure.

[0046] In some embodiments, a limiting ring 8 is provided between the limiting member 5 and the fixed base 1, and the limiting ring 8 is sleeved on the other end of the fixed rod 2. The limiting ring 8 can increase the tightness of the connection between the limiting member 5 and the fixed base 1.

[0047] The main functions of this utility model are:

[0048] 1. By setting a limiting step on the blade fixing plate, the limiting step is snapped into the blade profile of the louver. At the same time, the blade fixing plate and the blade profile are fixedly connected by screws. The fixing rod on the fixing seat is inserted into the limiting step to achieve a tight fixation. In this way, the fixing rod and the blade profile are fixedly connected, which is more secure and reliable than the screw fixing method on the connectors on the market. It is suitable for the installation of louvered windows in large areas.

[0049] 2. At the same time, the use of bushings in conjunction with fixing seats can increase the load-bearing capacity of fixing rods, extend service life, and make them suitable for louver installation in larger areas.

[0050] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
