Description

Technical Field

[0001] This utility model relates to the field of outdoor awning technology, and in particular to an awning arm. Background Technology

[0002] Outdoor campsites or building awnings are equipped with outward-extending arms attached to the wall poles. These outward-extending arms are used to secure the awning fabric when extended, creating a large area of ​​shade.

[0003] The outward extension arm and the wall-mounted pole are connected by a linkage structure to achieve expansion and contraction. When contracted, due to the elasticity of the linkage, as well as product precision, wear and tear, an opening can easily form between the outward extension arm and the wall-mounted pole, preventing the bottom of the awning arm from fully closing when retracted. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide a sunshade arm. By setting a tension spring inside the wall-mounted rod, the adjusting rod is pulled to retract the outward arm onto the wall-mounted rod, and the lower end of the arm is locked by the cooperation of a buckle and a pin.

[0005] The technical solution adopted by this utility model is: A sunshade arm is characterized by comprising a wall-mounted rod and an outward-extending arm. The wall-mounted rod is fixed to a wall. The outward-extending arm is connected to the wall-mounted rod via a support rod and an adjusting rod. The support rod is connected to the top of the wall-mounted rod and the lower end of the outward-extending arm via pins. The adjusting rod is connected to the middle of the wall-mounted rod and the lower end of the outward-extending arm via pins. A sliding cavity is provided inside the wall-mounted rod, and a slider is provided in the sliding cavity. A fixing pin is provided above the sliding cavity, and a tension spring is provided between the slider and the fixing pin. The adjusting rod is fixed to the slider via a pin. When the support rod and the adjusting rod rotate downward, the outward-extending arm moves closer to the wall-mounted rod and aligns with it. The tension spring exerts an upward pulling force on the outward-extending arm and towards the wall-mounted rod.

[0006] Furthermore, a pneumatic rod is provided between the support rod and the wall-mounted rod. The main body end of the pneumatic rod is connected to the wall-mounted rod by a pin. The connection point is located between the support rod and the adjustment rod and the wall-mounted rod. The piston end of the pneumatic rod is connected to the support rod by a pin.

[0007] Furthermore, the support rod has a groove-shaped cross-section, forming a cavity, and the pneumatic rod is located in the middle of the groove. When the support rod rotates and retracts, the pneumatic rod retracts into the cavity of the support rod.

[0008] Furthermore, the adjusting rod is divided into a front adjusting rod and a rear adjusting rod, which are connected by a sleeve. An adjusting component is provided at the connection point to adjust the length of the adjusting rod.

[0009] Furthermore, a buckle is provided at the lower end of the outward extension arm, and a locking pin is provided at the lower end of the wall-mounted rod. The buckle's snapping direction is the same as the rotation direction of the outward extension arm, and the locking pin is perpendicular to the rotation direction of the outward extension arm. When the outward extension arm is retracted to the wall-mounted rod position, the buckle and the locking pin engage to lock it in place.

[0010] Furthermore, the buckle is located inside the cavity of the outward-extending arm, and the locking pin is located inside the cavity of the wall-mounted rod.

[0011] The beneficial effects of this utility model are: (1) Install a tension spring between the adjusting rod and the wall-mounted rod to transmit the tension to the outward arm through the adjusting rod, so that the outward arm is subjected to a tension in the direction of the wall-mounted rod, so that the outward arm and the wall-mounted rod are brought together; (2) Buckles and pins are installed at the bottom of the outward extension arm and the wall-mounted rod, so that the outward extension arm is locked to the wall-mounted rod when it is retracted; (3) All newly installed components are stored in the cavities of the outward extension arm and the wall-mounted rod, without affecting the overall appearance.

[0014] The specific embodiments of the sunshade arm of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] See appendix Figure 1 The awning arm of this patent includes a wall-mounted rod 1 and an outward-extending arm 2. The wall-mounted rod 1 is used to fix it to the side of the wall. The outward-extending arm 2 is connected to the wall-mounted rod 1 through a support rod 3 and an adjusting rod 4. Through the relative movement of the support rod 3 and the adjusting rod 4, the outward-extending arm 2 can extend outward from the vertically retracted state and flip to the unfolded state; or the outward-extending arm 2 can retract downward and inward from the unfolded state to the vertically retracted state.

[0016] See appendix Figure 2 The support rod 3 is connected to the top of the wall-mounted rod 1 and the lower end of the outward-extending arm 2 via pins 5. A pneumatic rod 6 is installed between the support rod 3 and the wall-mounted rod 1. The main body of the pneumatic rod 6 is connected to the wall-mounted rod 1 via pins 5, and the connection point is located between the support rod 3 and the connection point between the adjusting rod 4 and the wall-mounted rod 1. The piston end of the pneumatic rod 6 is connected to the support rod 3 via pins 5.

[0017] The support rod 3 has a groove-shaped cross section, forming a cavity. The pneumatic rod 6 is located in the middle of the groove. When the support rod 3 rotates and retracts, the pneumatic rod 6 retracts into the cavity of the support rod 3.

[0018] The adjusting rod 4 is connected to the middle position of the wall-mounted rod 1 and the lower end of the outward arm 2 via the shaft pin 5. The adjusting rod 4 is divided into a front adjusting rod 7 and a rear adjusting rod 8, which are connected by a sleeve. An adjusting component 9 is set at the connection point to adjust the length of the adjusting rod 4.

[0019] See appendix Figure 3 A sliding cavity 10 is provided inside the wall-mounted rod 1. A slider 11 is provided in the sliding cavity 10. A fixing pin 12 is provided above the sliding cavity 10. A tension spring 13 is provided between the slider 11 and the fixing pin 12. An adjusting rod 4 is fixed to the slider 11 by a connecting shaft pin 5. When the support rod 3 and the adjusting rod 4 rotate downward, the outward arm 2 moves closer to the wall-mounted rod 1 and aligns with it. The tension spring 13 generates an upward pulling force on the outward arm 2 and in the direction of the wall-mounted rod 1.

[0020] See appendix Figure 4-7 A buckle 14 is provided at the lower end of the outward extension arm 2, and a locking pin 15 is provided at the lower end of the wall-mounted rod 1. The buckle 14 is located inside the cavity of the outward extension arm 2, and the locking pin 15 is located inside the cavity of the wall-mounted rod 1. The buckling direction of the buckle 14 is the same as the rotation direction of the outward extension arm 2, and the locking pin 15 is perpendicular to the rotation direction of the outward extension arm 2. When the outward extension arm 2 is retracted to the position of the wall-mounted rod 1, the buckle 14 and the locking pin 15 cooperate to lock.

[0021] The working process of the awning arm of this patent is divided into two parts: the outward extension arm retraction process and the outward extension process.

[0022] When retracting, push the outward extension arm 2 inward. At this time, the pneumatic rod 6 retracts, and the adjusting rod 4 rotates as the outward extension arm 2 retracts. The tension spring 13 generates an upward pulling force on the slider 11 at the end of the adjusting rod 4. The pulling force is decomposed into a pulling force on the outward extension arm 2 towards the wall rod 1, causing the outward extension arm 2 to retract onto the wall rod 1. At this time, when the lower ends of the two are close together, the buckle 14 at the lower end of the outward extension arm 2 retracts downward and inward, and it engages with the locking pin 15 at the lower end of the wall rod 1 to lock in place. The retraction operation of the outward extension arm 2 is completed.

[0023] When unfolded, the pneumatic rod 6 extends outward, causing the support arm 3 to open, which in turn pushes the outward arm 2, causing it to rotate upward and outward. At this time, the buckle 14 and the locking pin 15 disengage, and after disengagement, the outward arm completely separates from the wall-mounted rod, unfolding together with the adjusting rod. After fully unfolding, the pneumatic rod 6 maintains the supporting force on the support rod 3, so that the support rod 3 and the adjusting rod 4 maintain a stable supporting structure for the outward arm 2.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model (such as swapping the positions of the buckle and the pin). These improvements and modifications should also be considered within the scope of protection of this utility model.
