[0002] A tent is a shed that can be set up on the ground to shield against wind, rain, sunlight and provide temporary accommodation. It is usually made of canvas or other waterproof materials and is equipped with supporting things such as brackets or support rods. The support rod is the skeleton of the tent and is crucial for the stability and durability of the tent. Generally, it is made of steel pipes with relatively high strength.

[0019] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0020] Refer to Figure 1As shown in the figure, a steel pipe for a tent support rod includes a connecting pipe 1. Extension pipes 2 are slidably connected to both ends of the connecting pipe 1. Both the connecting pipe 1 and the extension pipes 2 are made of stainless steel material. The stainless steel material has high strength and corrosion resistance, enabling the connecting pipe 1 and the extension pipes 2 to have a long service life. External thread structures are provided at both ends of the connecting pipe 1, and internal thread structures matching the external thread structures are provided at the ends of the two extension pipes 2 facing each other. A limiting component is provided on the connecting pipe 1 to limit the sliding of the extension pipes 2. When the steel pipe is in normal use, the two extension pipes 2 on the connecting pipe 1 can be slid outwards, so that the two extension pipes 2 are away from each other. When the extension pipes 2 slide to the outermost ends of the connecting pipe 1, the extension pipes 2 are rotated, so that the external thread structure and the internal thread structure are threadedly connected together, thereby realizing the fixation between the extension pipes 2 and the connecting pipe 1, making the overall steel pipe have high strength and good support effect. After the steel pipe is used, the extension pipes 2 can be rotated to release the threaded connection between the external thread structure and the internal thread structure, thereby releasing the fixation between the connecting pipe 1 and the extension pipes 2. Then, the two extension pipes 2 on the connecting pipe 1 can be slid inwards, so that the two extension pipes 2 are close to each other, thereby reducing the space occupied by the steel pipe and being convenient to carry. At the same time, the extension pipes 2 are limited by the limiting component, so that the extension pipes 2 are firmly fixed on the connecting pipe 1, thereby preventing the extension pipes 2 from sliding on the connecting pipe 1 and affecting the carrying process.

[0021] Refer to Figure 1 As shown in the figure, the limiting component includes two symmetrically arranged limiting rods 3. The limiting rods 3 are slidably connected in the connecting pipe 1 along the diameter direction of the connecting pipe 1. Through grooves 4 for the limiting rods 3 to pass through are provided on both the connecting pipe 1 and the extension pipes 2. A driving component for driving the limiting rods 3 to slide is provided in the connecting pipe 1. During the process of the extension pipes 2 sliding inwards, when the through grooves 4 on the connecting pipe 1 are aligned with the through grooves 4 on the extension pipes 2, the driving component can be controlled to drive the limiting rods 3 to slide in the connecting pipe 1 towards the through grooves 4 until they sequentially pass through the through grooves 4 on the connecting pipe 1 and the extension pipes 2. Then, the limiting rods 3 are limited by the through grooves 4 on both the connecting pipe 1 and the extension pipes 2, thereby realizing the fixation of the extension pipes 2 on the connecting pipe 1. Sliding the limiting rods 3 to sequentially disengage them from the through grooves 4 on the extension pipes 2 and the connecting pipe 1 can release the fixed state between the connecting pipe 1 and the extension pipes 2. Through the limitation and disengagement of the limiting rods 3 in the through grooves 4, the fixation and sliding of the fixed pipe on the connecting pipe 1 are realized, and the operation is relatively convenient.

[0022] Refer to Figure 1-4As shown in the figure, the two limiting rods 3 are fixedly connected by a connecting rod 5. By setting the connecting rod 5, the sliding of the two limiting rods 3 in the connecting pipe 1 can be carried out simultaneously. The driving assembly includes a number of springs 6 arranged in the connecting pipe 1. One end of the spring 6 is fixedly connected to the connecting rod 5, and the other end is fixedly connected to the inner wall of the connecting pipe 1. A driving rod 7 is fixedly connected to the side of the connecting rod 5 away from the spring 6, and the end of the driving rod 7 away from the connecting rod 5 penetrates through the side wall of the connecting pipe 1 and extends outside the connecting pipe 1. When the driving rod 7 is pressed downward, the driving rod 7 moves downward. Then the driving rod 7 exerts a pressure on the connecting rod 5, pushing the connecting rod 5 downward and driving the limiting rod 3 to sequentially disengage from the through slots 4 on the extension pipe 2 and the connecting pipe 1. At the same time, the spring 6 is compressed due to the pressure exerted on it by the connecting rod 5. When the hand pressing the driving rod 7 is released, the pressure exerted by the driving rod 7 on the connecting rod 5 disappears, and the pressure exerted by the connecting rod 5 on the spring 6 also disappears. Then the spring 6 returns to its original shape and exerts an upward thrust on the connecting rod 5, driving the connecting rod 5 upward and thus driving the limiting rod 3 to automatically pass through the through slot 4. The operation is relatively convenient. A round rod 8 is arranged in the connecting pipe 1, and the spring 6 is penetrated by the round rod 8. A round groove 9 for the round rod 8 to pass through is formed in the connecting rod 5. The round rod 8 plays a guiding role in the expansion and contraction of the spring 6, enabling the spring 6 to expand and contract along the length direction of the round rod 8 during the expansion and contraction process, thereby preventing the spring 6 from bending and offsetting during the expansion and contraction process.

[0023] Refer to Figure 2 As shown in the figure, a number of protrusions 10 for abutting against the extension pipe 2 are arranged on the connecting pipe 1. When the extension pipe 2 abuts against the protrusions 10, the through slots 4 on the extension pipe 2 and the connecting pipe 1 are aligned. During the process of fixing the extension pipe 2 to the connecting pipe 1, only by sliding the extension pipe 2 until it abuts against the protrusions 10 can the through slots 4 on the extension pipe 2 and the connecting pipe 1 be aligned, thus facilitating the passing of the limiting rod 3. The operation is relatively convenient. A sliding sleeve 11 for abutting against the end face of the driving rod 7 is slidably connected to the connecting pipe 1. After pressing the driving rod 7 downward, the sliding sleeve 11 can be slid so that its inner surface abuts against the end face of the driving rod 7, thereby replacing the human hand to continuously exert pressure on the driving rod 7. The operation is easy and labor-saving.
