Description

Technical Field

[0001] This utility model relates to the field of retractable arm awnings, and in particular to an adjustable angle arm mount assembly and a retractable arm awning. Background Technology

[0002] A retractable arm awning is a sunshade device consisting of a flexible and foldable metal arm (retractable arm), a canopy, and a drive system. The canopy is unfolded and retracted through the extension, retraction, or rotation of the retractable arm. Suitable for various outdoor scenarios, it combines sunshade, rain protection, space optimization, and aesthetic appeal.

[0003] To meet the need for adjusting the shading angle, adjustable-angle retractable awnings have appeared on the market. The drawback of this type of retractable awning is that when the awning is exposed to a downward or upward wind, the retractable arm will rotate, making it impossible to guarantee the stability of the adjustable angle. Summary of the Invention

[0004] Based on this, this application provides an adjustable angle arm assembly to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable angle arm seat assembly, including an arm seat body, a curved arm assembly, and further including a rotating assembly disposed in the arm seat body, one end of the curved arm assembly being hinged to the rotating assembly; an adjustment assembly for controlling the rotation angle of the rotating assembly within the arm seat body; and a locking assembly cooperating with the rotating assembly to restrict the rotation of the curved arm assembly after the angle is adjusted.

[0006] In the above technical solution, further, a first interval and a second interval are formed within the main body of the arm seat to accommodate and connect the rotating component and the adjusting component.

[0007] In the above technical solution, the rotating assembly further includes: a shaft body placed within the first interval, wherein a locking cavity is provided therein; a cover disposed on one side of the shaft body and rotating synchronously with the shaft body; a hinge seat disposed on the other side of the shaft body and rotating synchronously with the shaft body; one end of the crank arm assembly is hinged to the hinge seat; and the shaft body, cover, and hinge seat are provided with aligned arc-shaped adjustment grooves.

[0008] In the above technical solution, the adjustment component further includes an adjustment block, which is placed within the second interval and is always within the adjustment area of ​​the arc-shaped adjustment groove. The adjustment block includes an adjustment surface on one side and a limiting surface on the other side. The adjustment surface cooperates with the arc-shaped adjustment groove, and the limiting surface is close to the side of the second interval to restrict the rotation of the adjustment block. An adjustment screw vertically penetrates the arm seat body and passes through the adjustment block within the second interval. The adjustment screw is provided with an adjustment threaded section and an anti-disengagement threaded section.

[0009] In the above technical solution, the locking assembly further includes a locking lever, comprising a trigger lever and a pressing lever, wherein the crank arm assembly, the trigger lever, and the pressing lever rotate coaxially; a locking block, located within the locking cavity of the shaft, wherein an elastic cavity is provided at the bottom of the locking cavity, and an elastic element is provided abutting against the locking block; the locking block is provided with a pressing hole for the pressing lever to be inserted; and the shaft is provided with a travel groove for accommodating the pressing lever.

[0010] In the above technical solution, in the initial state, the crank arm assembly squeezes the trigger lever, which in turn presses the pressing lever, so that the locking block is fully retracted into the locking cavity. In the unfolded state, the crank arm assembly is acted upon by the elastic element, causing the locking block to extend out of the locking cavity and contact the adjusting block.

[0011] In the above technical solution, the rear end of the arc-shaped adjustment groove of the shaft, the cover, and the hinge seat is provided with an alignment limiting groove, and a limiting rib placed in the limiting groove is provided on the inner wall of the first section of the arm seat body.

[0034] Reference Figure 1 As shown, a retractable arm awning includes a main body 6 with a cover, and an adjustable arm mount assembly is installed on the main body 6. When opened, the retractable arm mount assembly pulls out the leading edge with the awning cloth. By adjusting the arm mount assembly, the angle between the awning cloth and the main body 6 is controlled to change, further enhancing the sunshade effect.

[0035] refer to Figure 2-15 As shown, the arm support assembly on the articulated canopy has a specific structure. The arm support assembly includes an arm support body 1, an articulated arm assembly 2, and a rotating assembly 3, an adjusting assembly 4, and a locking assembly 5 disposed within the arm support body 1. The articulated arm assembly 2 is hinged to the rotating assembly 3. The adjusting assembly 4 disposed within the rotating assembly 3 controls the angle of rotation of the rotating assembly 3 within the arm support body 1, and after adjustment, the locking assembly 5 locks its position to prevent the rotating assembly 3 from rotating back.

[0036] Specifically, the arm support body 1 includes a hook portion on the rear side for fixing and a cavity on the front side for accommodating the rotating component 3, the adjusting component 4, and the locking component 5. The cavity is composed of a first section 101 for accommodating the rotating component 3 and a second section 102 for accommodating the adjusting component 4. The locking component 5 is located inside the rotating component 3. The first section 101 is circular, and the second section 102 is longitudinally rectangular. The first section 101 and the second section 102 are interconnected.

[0037] The rotating assembly 3 includes a shaft 301, a hinge 303, and a cover 302. Specifically, the shaft 301 is completely housed within the arm support body 1, and both the hinge 303 and the cover 302 have one end embedded within the arm support body 1. Therefore, steps are formed on both the hinge 303 and the cover 302. To ensure synchronous rotation of the shaft 301, hinge 303, and cover 302, a locking bolt is provided on one side of the cover 302. This locking bolt passes through the shaft 301 from the cover 302 and screws into the hinge 303, securing the three components together. Simultaneously, on the shaft... The body 301 has a locking cavity 3011 facing the second interval 102. The locking assembly 5 is installed in the locking cavity 3011. Two parallel hinge plates are provided at the other end of the hinge seat 303. The hinge plates are arc-shaped and have a through shaft hole at the center. Parallel hinge plates of the same shape are also provided at one end of the crank arm assembly 2. The inner distance between the two hinge plates of the crank arm assembly 2 is the outer distance between the two hinge plates of the hinge seat 303. A rotating shaft is provided to pass through the four hinge plates. It should be noted that a bearing is provided in the hinge plate hole of the crank arm assembly 2 so that the crank arm assembly 2 can rotate on the hinge seat 303.

[0038] At the same time, it should be noted that an annular groove is provided on the upper hinge plate position on the rotating shaft, which is equivalent to the hinge seat 303. A fastening plug is provided on the outside of the upper hinge plate and abuts against the bottom wall of the annular groove, thereby preventing the rotating shaft from disengaging.

[0039] Aligned arc-shaped adjustment grooves 304 are provided on the shaft 301, the cover 302, and the hinge 303, and the adjustment component 4 can move within the adjustment range of the arc-shaped adjustment grooves 304.

[0040] The adjustment component 4 includes an adjustment block 401 and an adjustment screw 402. The adjustment block 401 is completely disposed within the second interval 102 and moves in the longitudinal direction within the second interval 102. It should be noted that the movement range of the adjustment block 401 is also within the arcuate range of the arcuate adjustment groove 304. The adjustment block 401 includes an adjustment surface 4011 on one side and a limiting surface 4012 on the other side. The adjustment surface 4011 is an arcuate surface, and the limiting surface 4012 is a vertical plane. The arcuate surface is placed within the arcuate adjustment groove 304, and the limiting surface 4012 is close to the side of the second interval 102. Under the action of the adjustment screw 402, the adjustment block 401 will move on the adjustment screw 402. Under the restriction of the limiting surface and the wall, the rotation of the adjustment block 401 on the adjustment screw 402 can be restricted.

[0041] The adjusting screw 402 extends from the longitudinal position of the second interval 102, penetrating the arm support body 1 from bottom to top, and also penetrating the adjusting block 401 located within the second interval 102. It should be noted that the adjusting screw 402 is arranged from bottom to top for easy adjustment, since the arm support body 1 is installed in the main body of the articulated canopy. Moreover, it is worth noting that the adjusting screw 402 can only rotate on the arm support body 1, but it is necessary to prevent the adjusting screw 402 from detaching from the arm support body 1. The adjusting screw 402 is provided with an adjusting threaded section 4021 and an anti-detachment threaded section 4022. The adjusting threaded section 4021 is located within the second interval 102, and the anti-detachment threaded section 4022 is located on the outside, with a nut screwed onto the anti-detachment threaded section 4022.

[0042] Furthermore, to facilitate users in knowing the exact angle being adjusted, a pointer 4013 pointing to the side wall of the second interval 102 is provided on the end face of the adjustment block 401. At the same time, a longitudinally arranged angle scale 104 is provided at a corresponding position on the arm seat body 1 on the side wall of the second interval 102. When the adjustment screw 402 is rotated, the position of the adjustment screw 402 remains unchanged, and the adjustment block 401 moves within the adjustment thread interval 4021 of the adjustment screw 402.

[0043] The locking assembly 5 includes a locking lever 501 and a locking block 502. Specifically, the locking lever 501 is located at the hinge joint between the hinge seat 303 and the crank arm assembly 2. The locking lever 501 includes two parts: a trigger lever 5011 and a pressing lever 5012. The trigger lever 5011 is hollow and double-layered. The pressing lever 5012 is inserted into the hollow section of the trigger lever 5011. A trigger handle is provided on the trigger lever 5011, located at the rear of the crank arm assembly 2. When the crank arm assembly 2 contacts the trigger handle, the trigger lever 5011 rotates. The pressing lever 5012 is provided with a pressing rod and a pressing angle that cooperates with the trigger lever 5011. The locking block 502 is disposed within the locking cavity 3011 of the shaft 301 to ensure... The automatic ejection of the locking block 502 is achieved by providing an elastic cavity 3012 at the bottom of the locking cavity 3011 (opposite to the opening of the locking cavity 3011), and an elastic element 5021 within the elastic cavity 3012. Preferably, the elastic element 5021 is a spring, and the elastic element 5021 abuts against the rear end of the locking block 502. It should be noted that a strip-shaped through hole is provided on the hinge seat 303, located at the center of the two hinge plates of the hinge seat 303. The pressing rod on the pressing lever 5012 enters the strip-shaped through hole. The shaft 301 and the locking block 502 are respectively provided with a pressing hole 5022 and a travel groove 3013. The end of the pressing rod passes through the travel groove 3013 and abuts against the rear wall of the pressing hole 5022 (towards the side of the elastic element 5021).

[0044] When the crank arm assembly 2 is in the retracted state, it presses the trigger lever 5011, causing it to contact the pressing angle on the pressing lever 5012. The pressing lever 5012 rotates, pressing the locking block 502 against the elastic member 5021. The elastic member 5021 is compressed, completely placing the locking block 502 within the locking cavity 3011. During the transition from the retracted to the extended state, the crank arm assembly 2 rotates, causing the… As the trigger lever 5011 gradually reduces the squeezing force, the pressing lever 5012 simultaneously reduces the pressure on the locking block 502. Through the elastic element 5021, the locking block 502 gradually moves towards the opening of the locking cavity 3011. When the crank arm assembly 2 rotates a certain angle but is not fully extended, it can no longer press the trigger lever 5011, and the locking block 502 can fully extend out of the locking cavity 3011. The locking block 502 can abut against the adjustment surface 4011 of the adjustment block 401.

[0045] Furthermore, in order to ensure that the locking block 502 slides smoothly in the locking cavity 3011, guide ribs 5023 are provided at the upper and lower ends and on the left and right sides of the locking block 502, and guide grooves that cooperate with the guide ribs 5023 are provided in the locking cavity 3011.

[0046] Meanwhile, in order to prevent the rotating component 3 from rotating excessively, a similarly aligned limiting groove 305 is provided at the rear end of the shaft 301, the cover 302, and the hinge seat 303 (on the side away from the arc-shaped adjustment groove 304). At the same time, a limiting rib 103 is provided on the inner wall of the first section 101 of the arm seat body 1, and the limiting rib 103 is placed within the range of the limiting groove 305.

[0047] The working process of this utility model: (Refer to...) Figure 4-8 As shown, in the initial state, when the arm support assembly is not adjusted, the pointer 4013 points to 0°, the lower arc surface of the arc-shaped adjustment groove 304 is in contact with the lower arc surface of the adjustment surface 4011 of the adjustment block 401, the elastic element 5021 is in a compressed state, and the locking block 502 is completely placed in the locking cavity 3011. In this state, when the crank arm assembly 2 is opened, the elastic element 5021 is in a natural state, the locking block 502 is completely extended out of the locking cavity 3011 and is in contact with the upper arc surface of the adjustment surface 4011 of the adjustment block 401. At this time, the lower arc surface of the arc-shaped adjustment groove 304 is also in contact with the lower arc surface of the adjustment surface 4011 of the adjustment block 401. At this time, the arm support assembly is adjusted by rotating the adjustment screw 402, so that the adjustment block 401 is within the second interval 102. Moving upwards, preferably, the pointer 4013 points to 20°. At this time, the leading edge of the crank arm assembly 2 drops, causing the lower arc surface of the arc-shaped adjustment groove 304 of the rotating assembly 3 to always be in contact with the lower arc surface of the adjustment surface 4011 of the adjustment block 401. At this time, the locking block 502 is always in contact with the upper arc surface of the adjustment block 401. In this state, the crank arm assembly 2 is retracted. When the crank arm assembly 2 is retracted to a certain angle, the crank arm assembly 2 re-presses the trigger lever 5011 and drives the pressing lever 5012 to press the locking block 502 again. The elastic element 5021 is recompressed, and the locking block 502 is completely retracted into the locking cavity 3011 again. At this time, the leading edge of the crank arm assembly 2 is retracted to the vicinity of the main body 6, and the rotating assembly 3 starts to return to center again.
