Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, and in particular to an adjustment device for balancing the left and right curved arms of a sunshade. Background Technology

[0002] Awnings are typically installed on walls above doors or windows to provide shade and rain protection. Generally, an awning consists of a housing, two connectors, two folding arms (also called curved arms), and a sunshade roll. The housing is fixedly attached to the wall, the two connectors are fixedly attached to the housing, one end of each folding arm is rotatably connected to a connector, and one end of the sunshade roll is attached to the housing, while the other end is attached to the end of each folding arm furthest from the connector. The extension and retraction of the two folding arms coordinates with the opening and rolling of the sunshade roll. Therefore, maintaining balance between the two folding arms is crucial; otherwise, the arms may not retract or the housing may not close properly.

[0003] Utility model patent CN216865766U discloses an adjustment component for adjusting the angle of a sunshade. Based on the disclosed technical content and accompanying drawings, its working principle is as follows: Sliding the two adjustment rods 7 causes the adjustment rod 7 above the swing part 51 to separate from the abutment part 52, while the adjustment rod 7 below the swing part 51 abuts against the abutment part 52. This causes the swing part 51 to tilt upwards within the through hole 611, which in turn causes the folding arm 3 to tilt upwards, thereby increasing the angle between the sunshade and the wall. Sliding the two adjustment rods 7 causes the adjustment rod 7 above the swing part 51 to abut against the abutment part 52, while the adjustment rod 7 below the swing part 51 separates from the abutment part 52. This causes the swing part 51 to swing downwards within the through hole 611, which in turn causes the folding arm 3 to swing downwards, thereby reducing the angle between the sunshade and the wall. The swinging part uses the limiting rod as the pivot. The upper and lower adjusting rods of the swinging part are connected to the abutment part and moved away from the abutment part, so that the swinging part swings, adjusts the angle of the folding arm, and thus adjusts the angle between the sunshade and the wall.

[0004] However, when adjusting the angle of a single crank arm, the aforementioned adjustment components require simultaneous adjustment of the upper and lower adjustment rods of the swing section each time, which means adjustments are needed twice, making them rather cumbersome to use. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an adjustment device for balancing the left and right curved arms of a sunshade, which solves the problem of cumbersome adjustment of the curved arm angle in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an adjustment device for balancing the left and right curved arms of a sunshade, including a swinging part, an adjustment seat and a pin. The swinging part includes a swinging part, a connecting part fixed to the swinging part, and a plug-in part rotatably connected to the connecting part. The adjustment seat has at least one receiving cavity with an opening on one end face. The swinging part is placed in the receiving cavity through the opening. The pin passes between the two sides of the adjustment seat and through the shaft hole on the swinging part. The shaft hole is located at one end of the swinging part near the connecting part. The adjustment device also includes an adjustment member. The top surface of the adjustment seat has an adjustment hole communicating with the receiving cavity. The adjustment member is screwed to the adjustment hole, and the bottom end of the adjustment member abuts against the end of the swinging part away from the connecting part.

[0007] As a further embodiment, the top of the adjusting member is provided with a driving part.

[0008] As a further embodiment, the adjusting device also includes a nut, which is screwed onto the adjusting member and abuts against the top surface of the adjusting seat.

[0009] As a further embodiment, both end faces of the adjusting seat are provided with openings that communicate with the receiving cavity.

[0010] As a further embodiment, the top surface of the adjusting seat has two adjusting holes, which are arranged along the length of the adjusting seat and are mirror-symmetrical about the center line of the top surface of the adjusting seat.

[0011] As a further embodiment, mounting holes are provided on both sides of the adjusting seat, and both ends of the pin are installed in the mounting holes.

[0012] The adjustment seat has two mounting holes on the same side. The two mounting holes on the same side are arranged along the length of the adjustment seat and are mirror-symmetrical about the center line of the side.

[0013] As a further embodiment, a number of elastic elements are provided between the end face of the adjusting seat and the connecting part, and in the vertical direction, the elastic elements are located above the pin.

[0014] The adjusting seat has several blind holes on its end face, and one end of the elastic element is stuck in the blind holes.

[0015] As a further embodiment, blind holes are provided on both end faces of the adjusting seat;

[0016] The adapter portion has a positioning hole on the side facing the adjustment seat that matches the elastic element.

[0017] As a further solution, the adjusting seat is integrally formed with a fixing plate, and the fixing plate has several fixing holes.

[0018] As a further embodiment, in the vertical direction, the width of the swinging part gradually increases from the end away from the adapter to the end closer to the adapter.

[0019] The beneficial effects of this utility model are:

[0020] 1. Only the adjustment component needs to be adjusted. The height and tilt angle of one crank arm can be adjusted with one adjustment, so that the height and tilt angle of the left and right crank arms are consistent, ensuring that the two are balanced, which is relatively simple to use.

[0021] 2. When the adjusting component is turned, it moves downward and presses against the swinging part. Since the bottom end of the adjusting component abuts against the end of the swinging part away from the adapter, the swinging part, with the pin as its fulcrum, tilts upward at the end near the adapter, causing the adapter, the insertion part, and the crank arm connected to the insertion part to tilt upward, thereby increasing their tilt angle. This ensures that the left and right crank arms maintain the same height and tilt angle, ensuring balance between them. When the adjusting component is turned, it moves upward and disengages from the swinging part. At this time, under the gravity of the crank arm, the swinging part, with the pin as its fulcrum, swings downward at the end near the adapter, causing the adapter, the insertion part, and the crank arm connected to the insertion part to swing downward, thereby decreasing their tilt angle. This adjusts the height and tilt angle of one crank arm, ensuring that the left and right crank arms maintain the same height and tilt angle, ensuring balance between them.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] As attached Figure 1-4 As shown, this utility model provides an adjustment device for balancing the left and right curved arms 7 of a sunshade, including a swing element 1, an adjustment seat 2, and a pin 3, as shown in the attached figure. Figure 4 As shown, the ornament 1 includes a swinging part 11, a connecting part 12 fixedly connected to the swinging part 11 (the connection can be welded or integrally formed, preferably integrally formed), and a plug-in part 13 rotatably connected to the connecting part 12. The plug-in part 13 and the connecting part 12 can be rotatably connected via a pin 3, thereby enabling rotation between the connecting part 12 and the plug-in part 13. (See attached...) Figure 7 As shown, the insertion part 13 is used to insert and fix it inside the arm tube of the crank arm 7, so that the crank arm 7 can rotate relative to the swing part 11.

[0032] The adjusting seat 2 is fixedly installed on the wall casing, as shown in Appendix 3. The adjusting seat 2 has at least one receiving cavity 21 with an opening 22 on one end face. The swinging part 11 passes through the opening 22 and is placed in the receiving cavity 21. Specifically, the purpose of providing the opening 22 is to allow the swinging part 11 to enter the receiving cavity 21. Therefore, an opening 22 communicating with the receiving cavity 21 can be provided on one or both end faces of the adjusting seat 2. Preferably, both end faces of the adjusting seat 2 are machined with openings 22 communicating with the receiving cavity 21. One purpose is to facilitate viewing the swinging of the swinging part 11 in the receiving cavity 21 from the opening 22 away from the adapter 12. Another purpose is to allow the two left and right curved arms 7 to use the same adjusting seat 2, thereby improving the compatibility of the parts and making it more convenient to assemble the sunshade. In addition, the receiving cavity 21 is rectangular, and the rectangular shape of the receiving cavity 21 is easy to process.

[0033] Furthermore, as attached Figure 1 , 3As shown in Figure 4, the pin 3 passes between the two sides of the adjusting seat 2 and through the shaft hole 111 on the swing part 11. The shaft hole 111 is located at one end of the swing part 11 near the adapter 12. Specifically, mounting holes 26 are provided on both sides of the adjusting seat 2, and both ends of the pin 3 are installed in the mounting holes 26, which facilitates the installation of the pin 3. Preferably, in the vertical direction, the shaft hole 111 is located above the center line of the swing part 11. On the one hand, the pin 3 causes the swing part 11 to swing within the receiving cavity 21, thereby adjusting the tilt angle of the crank arm 7, thus ensuring that the left and right crank arms 7 maintain the same height and tilt angle, and ensuring that the two are balanced; on the other hand, the pin 3 positions and limits the swing part 11, locking it within the receiving cavity 21 and preventing it from disengaging.

[0034] As attached Figure 3 As shown, the adjustment device also includes an adjustment component 4. The top surface of the adjustment seat 2 has an adjustment hole 23 communicating with the receiving cavity 21. The adjustment component 4 is screwed to the adjustment hole 23, and the bottom end of the adjustment component 4 abuts against the end of the swing part 11 away from the adapter 12. The adjustment component 4 can be a screw. When the adjustment component 4 is turned, the adjustment component 4 moves down and presses the swing part 11. Since the bottom end of the adjustment component 4 abuts against the end of the swing part 11 away from the adapter 12, the swing part 11 uses the pin 3 as a fulcrum, and the end of the swing part 11 near the adapter 12 tilts upward, causing the adapter 12, the insertion part 13 and the crank arm 7 connected to the insertion part 13 to tilt upward, thereby increasing their tilt angle, so that the left and right crank arms 7 maintain the same height and tilt angle, and ensure that the two are balanced. When the adjusting part 4 is turned, it moves upward and disengages from the swing part 11. At this time, under the gravity of the crank arm 7, the swing part 11 swings downward with the pin 3 as the fulcrum, and the end of the swing part 11 near the adapter 12 swings downward, causing the adapter 12, the plug 13 and the crank arm 7 connected to the plug 13 to swing downward, thereby reducing its tilt angle, and thus adjusting the height and tilt angle of one crank arm 7, so that the height and tilt angle of the left and right crank arms 7 are consistent, and the two are kept in balance.

[0035] Throughout the process, only the adjusting component 4 needs to be adjusted. With one adjustment, the height and tilt angle of one crank arm 7 can be adjusted, so that the height and tilt angle of the left and right crank arms 7 are consistent, ensuring that the two are balanced, which is relatively simple to use.

[0036] For details, see attached. Figure 5 As shown, the top of the adjusting member 4 is provided with a driving part 41. The driving part 41 can be a flat slot or a cross slot that is compatible with a screwdriver, or an internal hex slot that is compatible with a hex wrench. By inserting a tool such as a screwdriver or a hex wrench into the flat slot, cross slot, or internal hex slot, the driving part 41 is turned to apply force, thereby driving the adjusting member 4 to rotate.

[0037] In some embodiments, as shown in the appendix Figure 2 As shown, the adjustment device also includes a nut 5, which is screwed onto the adjustment member 4 and abuts against the top surface of the adjustment seat 2. By locking the adjustment member 4 with the nut 5, the swinging part 11 is prevented from swinging due to the loosening of the adjustment member 4, thus affecting the tilt of the crank arm 7 and preventing imbalance between the left and right sides of the crank arm 7.

[0038] In some embodiments, as shown in the appendix Figure 1 As shown, the top surface of the adjusting seat 2 has two adjusting holes 23. These two holes 23 are arranged along the length of the adjusting seat 2 and are mirror-symmetrical about the center line of the top surface of the adjusting seat 2. This allows the adjusting seat 2 to be used for both left and right curved arms 7, improving the compatibility of the parts and making the assembly of the sunshade more convenient. It should be noted that for each curved arm 7, only one of the two adjusting holes 23 on the top surface of the adjusting seat 2 needs to be used during installation.

[0039] As shown in Appendix 2, the adjusting seat 2 has two mounting holes 26 on the same side. These two mounting holes 26 are arranged along the length of the adjusting seat 2 and are mirror-symmetrical about the center line of the side. This allows the adjusting seat 2 to be used for both left and right crank arms 7, improving the compatibility of the parts. It should be noted that for each crank arm 7, only one of the two mounting holes 26 on the same side of the adjusting seat 2 needs to be used during installation.

[0040] In some embodiments, as shown in the appendix Figure 1-3 As shown, several elastic elements 6 are provided between the end face of the adjusting seat 2 and the connecting part 12. The elastic elements 6 can be springs. In the vertical direction, the elastic elements 6 are located above the pin 3. Specifically, several blind holes 24 are opened on the end face of the adjusting seat 2. One end of the elastic element 6 is inserted into the blind hole 24 to facilitate the fixation of the elastic element 6. The function of the elastic element 6 is twofold: firstly, when the bottom end of the adjusting part 4 abuts against the end of the swing part 11 away from the connecting part 12, there is an interaction force between the adjusting seat 2 and the connecting part 12 of the swing part 1, which makes the structure of the entire adjusting device more stable and reduces shaking; secondly, when the entire sunshade is subjected to a vertical force, it can buffer the swaying force, making the entire adjusting device more stable and the left and right curved arms balanced.

[0041] Furthermore, as attached Figure 4As shown, the adapter 12 has a positioning hole 121 for the elastic member 6 on the side facing the adjustment seat 2. When there is an interaction force between the adjustment seat 2 and the swing member 1, the elastic member 6 acts in the positioning hole 121 of the adapter 12 to ensure that the force of the elastic member 6 on the adapter 12 is stable. When the entire sunshade is subjected to a horizontal force, the elastic member 6 can buffer the swing of the left and right curved arms 7 on the horizontal plane, ensuring that the entire adjustment device is more stable.

[0042] Similarly, as attached Figure 1 , 6 As shown, blind holes 24 are provided on both ends of the adjusting seat 2, which also makes the adjusting seat 2 applicable to both left and right curved arms 7, improving the compatibility of parts and making it more convenient to assemble the sunshade.

[0043] During actual installation, as shown in the attached document Figure 1 As shown, the adjusting seat 2 has an integrally formed fixing plate 25. The fixing plate 25 has several fixing holes 251. Screws are passed through the fixing holes 251 to connect with the cover, so that the adjusting seat 2 can be connected and fixed to the cover, which is convenient for installation.

[0044] In the vertical direction, as shown in the attached image. Figure 3 As shown, the width of the swing part 11 gradually increases from the end away from the adapter 12 to the end closer to the adapter 12. When the swing part 11 is placed in the receiving cavity 21, there is space for the swing part 11 to swing between the end of the swing part 11 away from the adapter 12 and the inner wall of the receiving cavity 21.

[0045] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
