Description

Technical Field

[0001] The utility model relates to the technical field of louvered pavilions, in particular to a connecting mechanism for the opening and closing of the top louvers of a pavilion. Background Technique

[0002] In the Chinese patent application number "CN202223077973.4", a louvered pavilion transmission mechanism is proposed. The transmission rod is connected to the hinge hole through a screw rod. There is a rigid abutment between the hinge hole and the screw rod, which causes significant wear on the screw rod and even makes the thread groove ineffective, not conducive to subsequent maintenance, and there will be significant frictional noise after long-term use.

[0003] The assembly holes on the transmission rod in this patent are also designed for fixed positions, making it difficult to apply to different specifications of hinges and reducing the versatility of the components.

[0004] Therefore, this case will propose a new connecting mechanism for the opening and closing of the top louvers to reduce the wear between the hinge hole and the screw rod, improve the service life of the components, and enhance the versatility of the components. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages of large component wear and poor component versatility in the prior art, and to propose a connecting mechanism for the opening and closing of the top louvers of a pavilion.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a connecting mechanism for the opening and closing of the top louvers of a pavilion, including multiple groups of sequentially lapped fan blades. Rotating shafts are fixedly inserted at both the left and right ends of the fan blades. A rotating rod is fixedly installed on the outer end face of the fan blades. A transmission rod is arranged on one side of the rotating rod. An opening is formed on one side of the transmission rod to form a "C" - shaped structure. A sliding block is slidably installed inside the transmission rod. One end of the sliding block is integrally formed with a threaded column that can be inserted through the inside of the rotating rod. A rotating ring for slidably abutting against the rotating rod is movably sleeved around the periphery of the threaded column.

[0008] Preferably, nuts are threadedly installed on both the left and right sides of the rotating ring around the periphery of the threaded column. The width of the rotating ring is greater than the width of the rotating rod, and the two nuts respectively abut against the left and right ends of the rotating ring.

[0009] Preferably, a gasket is abutted between the nut and the transmission rod. The gasket includes an elastic split gasket.

[0010] Preferably, a partition part is integrally formed inside the transmission rod. The partition part divides the inside of the transmission rod into two regions, and an inner - folding structure is provided at the opening of the transmission rod.

[0011] Preferably, the sliding block has a polygonal structure.

[0012] Preferably, the sliding block has a circular structure, and a spline groove is formed at one outer end of the threaded column.

[0013] Preferably, bending portions are formed at both front and rear ends of the fan blade.

[0014] Preferably, an insertion portion for inserting the rotating shaft is integrally formed inside the fan blade.

[0015] Preferably, a rotating frame is rotatably clamped at one outer end of the rotating shaft, and the rotating frame is fixedly connected to an external frame.

[0016] Preferably, the rotating rod is fixedly installed at the upper and lower ends of the fan blade.

[0017] A connecting mechanism for opening and closing the top louvers of a gazebo proposed by the present utility model has the beneficial effects that:

[0018] Through the provided rotating ring, it is possible to avoid direct contact between the threaded column and the rotating rod, increase the contact area between components, reduce wear, and at the same time, the width of the rotating ring is greater than the width of the rotating rod, so that the fixing nut will not rigidly abut against the rotating rod, reducing the abutting contact between components;

[0019] Through the provided transmission rod, the fixing point can be freely adjusted, improving the applicability to hinges of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Refer to Figures 1-5 , here is an example of the implementation method of the main body:

[0032] A connecting mechanism for opening and closing the top louvers of a gazebo includes multiple groups of sequentially overlapping fan blades 1. Rotating shafts 2 are fixedly inserted at both the left and right ends of the fan blades 1, enabling the fan blades 1 to rotate around the rotating shafts 2. Multiple groups of fan blades 1 together form an opening and closing structure; a rotating rod 4 is fixedly installed on the outer end face of the fan blade 1 by welding or other means. A transmission rod 6 is arranged on one side of the rotating rod 4. One side of the transmission rod 6 forms a "C" - shaped structure. A sliding block 501 is slidably installed inside the transmission rod 6. One end of the sliding block 501 is integrally formed with a threaded post 5 that can be inserted through and into the inside of the rotating rod 4. A swivel 504 for slidably abutting against the rotating rod 4 is movably sleeved around the outer periphery of the threaded post 5;

[0033] Based on the above content, the transmission rod 6 is used to pull the rotating rod 4 provided on the fan blade 1, so that the fan blade 1 rotates around the rotating shaft 2. Multiple groups of fan blades 1 rotate synchronously to achieve the opening and closing effect of the louver; the open structure of the transmission rod 6 enables the free adjustment of the positions of the combination of the sliding block 501, threaded post 5, etc. inside the transmission rod 6, which can be applicable to the rotating rods 4 at different positions, improving the versatility of the components; the provided swivel 504 can reduce the wear generated between the rotating rod 4 and the threaded post 5, improving the service life of the components;

[0034] Furthermore, referring to Figure 3 , bending portions 101 are provided at both the front and rear ends of the fan blade 1, so that adjacent two groups of fan blades 1 can be overlapped through the bending portions 101 to form a blocking structure, preventing rainwater falling from the air from invading;

[0035] Furthermore, referring to Figure 2 , an insertion portion 102 for inserting the rotating shaft 2 is integrally formed inside the fan blade 1, and a hole groove for fixing the rotating shaft 2 can be provided inside the insertion portion 102;

[0036] Furthermore, referring to Figure 2, a rotating frame 3 is rotatably connected to one end of the outer side of the rotating shaft 2, and the rotating frame 3 is used to be fixed to the external frame;

[0037] For further reference, Figure 3 The rotating rod 4 is installed at both the upper and lower ends of the fan blade 1, so that the selectivity of the driving position of the fan blade 1 can be increased. The transmission rod 6 can be installed above or below the fan blade 1 according to actual needs.

[0038] Reference Figure 4 , 5 Here is an example of an implementation of the transmission rod 6:

[0039] A partition 601 is integrally formed inside the transmission rod 6, so that the transmission rod 6 can be divided into two groups of areas. While improving the strength of the transmission rod 6, the sliding block 501 and the external connecting parts can be installed in the two groups of areas respectively, thereby achieving the effect of separating functional areas and reducing functional interference; an inward folding structure should also be provided at the opening of the transmission rod 6 to confine the sliding block 501 to the inside of the transmission rod 6.

[0040] Reference Figure 6 Here is an example of an implementation of the sliding block 501:

[0041] When the sliding block 501 is a polygonal structure, the structure enables the sliding block 501 to only slide in the transmission rod 6 and cannot rotate, so as to improve the stability of the sliding block 501 and the transmission rod 6 through the sliding block 501 itself; when the sliding block 501 is a circular structure, a spline groove 505 is provided at one end of the outer side of the threaded column 5. When it is necessary to install the nut 502 on the outer thread of the threaded column 5, it is necessary to insert an external tool into the spline groove 505 to prevent the sliding block 501 from rotating so as to achieve the installation of the nut 502.

[0042] Reference Figure 6 Here is an example of an implementation of the swivel 504:

[0043] The outer periphery of the threaded column 5 is located on both sides of the left and right sides of the rotating ring 504, and nuts 502 are threadedly installed. The two sets of nuts 502 are used to limit the rotating rod 4 on the threaded column 5 to prevent it from falling off. The width of the rotating ring 504 is greater than the width of the rotating rod 4, so that the two sets of nuts 502 are respectively in contact with the left and right ends of the rotating ring 504, and are not forced to contact with the rotating rod 4, so as to reduce friction and noise, and prevent the threaded column 5 from being worn, making it difficult to remove the nuts 502;

[0044] Furthermore, a gasket 503 is abutted between the nut 502 and the transmission rod 6 . The gasket 503 may include an elastic opening gasket to improve stability and cooperate with the nut 502 to fix the sliding block 501 at a desired position in the transmission rod 6 .

[0045] Finally, on one side of the transmission rod 6, components such as a push rod can be rotatably installed to drive the displacement of the transmission rod 6. Since this part is prior art, it will not be elaborated here.

[0046] Based on the above examples of each embodiment, during assembly:

[0047] Insert the insertion part 102 of multiple groups of fan blades 1 into the rotating shaft 2, and fix the rotating shaft 2 to the external frame through the rotating frame 3 by means of bolts or the like;

[0048] Slide the combination of the required number of threaded posts 5 and sliding blocks 501 into the transmission rod 6, put the gasket 503 around the threaded post 5, and thread one set of nuts 502 onto the threaded post 5. At this time, the nut 502 can be slightly tightened to position the combination of the threaded post 5 and the sliding block 501 inside the transmission rod 6;

[0049] Put the rotating ring 504 around the threaded post 5, and sleeved the rotating rod 4 around the rotating ring 504. At this time, another set of nuts 502 can be threaded onto the threaded post 5. First, tighten the nut 502 on the side close to the transmission rod 6 to fix the combination of the threaded post 5 and the sliding block 501, and then tighten the nut 502 on the side far from the transmission rod 6 to restrict the rotating rod 4 on the rotating ring 504;

[0050] Finally, lubricating oil or other substances can be applied to the outer surface of the rotating ring 504 as needed to further reduce wear.

[0051] Based on the above examples of each embodiment, during use:

[0052] The rotating rod 4 contacts the threaded post 5 through the rotating ring 504, increasing the contact area, reducing the pressure per unit area, preventing the surface of the threaded post 5 from being damaged due to wear of the thread groove, and improving the convenience of subsequent maintenance.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
