Description

Technical Field

[0001] This utility model relates to the field of telescopic structures, and more specifically to a telescopic tent support. Background Technology

[0002] With the increasingly diverse applications of tents, the performance of the telescopic tent frame directly determines the outdoor experience. Telescopic tent frames typically rely on the coordinated extension and retraction of the inner and outer poles to flexibly adjust height. However, traditional telescopic tent frames lack attention and optimization regarding the friction relationship between the inner and outer poles. Most frames use simple metal tube connections, which not only feel stiff and difficult to pull, but also produce a harsh metallic friction sound. Prolonged high-intensity friction accelerates wear at the contact points between the inner and outer poles, further disrupting the tube diameter fit and causing increasing swaying during subsequent use. Furthermore, when the inner pole is extended, the inner and outer poles are fixed in length by a locking assembly. If the locking assembly fails to engage during extension, allowing the inner pole to continue extending, the guide slider at one end of the inner pole may be pulled out, damaging the telescopic tent and rendering it unusable.

[0003] Therefore, it is of great significance to provide a tent telescopic frame that reduces friction, is easy to pull out, and is durable and stable. Utility Model Content

[0004] In view of this, the present invention provides a tent telescopic support frame that is not only durable and stable, but also reduces the friction between the pole walls, making the inner and outer poles smoother during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a telescopic tent support frame, comprising:

[0007] The outer rod is cylindrical;

[0008] A connecting pipe has a receiving groove formed from the inside to the outside on its inner wall. A through hole is formed on the wall of the connecting pipe, and the through hole is corresponding to the receiving groove. A positioning post is fixedly connected to the bottom of the receiving groove, and a spring is sleeved on the positioning post. The bottom end of the connecting pipe is sleeved on the top end of the outer rod and fixedly connected to the top end of the outer rod.

[0009] A pressing component, one end of which passes through the through hole and the other end of which is in contact with the spring;

[0010] The inner rod is cylindrical and has a blind hole on its wall. The inner rod has a threaded inner wall and a guide block is fixedly connected to its bottom end. The bottom end of the guide block has a connecting hole, and the top end of the connecting tube is sleeved on the bottom end of the inner rod.

[0011] The telescopic device has its bottom end fixedly connected to the inner bottom end of the outer rod, and its top end passes through the connecting hole and is threadedly connected to the inner wall of the thread.

[0012] Preferably, the pressing component includes a pressing member and a limiting post. The pressing member is annular, with one end passing through the through hole and the other end fitting against the spring. The limiting post is fixedly connected to the inner wall of the pressing member near the end of the spring.

[0013] Preferably, the end of the pressing member away from the spring has a corrugated surface.

[0014] Preferably, the diameter of the blind hole is the same as the outer diameter of the limiting post.

[0015] Preferably, the telescopic device includes a motor and a rotating shaft. The bottom end of the motor is fixedly connected to the inner bottom end of the outer rod, and the output end of the motor is fixedly connected to the bottom end of the rotating shaft. The top end of the rotating shaft is provided with a thread, and the top end of the rotating shaft passes through the connecting hole. The thread is threadedly connected to the inner wall of the thread.

[0016] Preferably, the diameter of the connecting hole is smaller than the outer diameter of the thread, the outer diameter of the inner rod is smaller than the inner diameter of the outer rod, and the outer diameter of the guide slider is the same as the inner diameter of the outer rod.

[0017] Preferably, a sliding protrusion is fixedly connected to the inner wall of the connecting pipe, a strip groove is formed on the sliding protrusion, and a plurality of balls are arranged in the strip groove.

[0018] Preferably, the outer rod and the inner rod are made of aluminum alloy.

[0019] The present invention discloses the following technical effects:

[0020] 1. This utility model is equipped with a telescopic device. When it is started, the length of the inner rod can be adjusted. When it is stopped, the length of the telescopic bracket can be fixed to any desired length. When the telescopic length is at its maximum, the limit post automatically engages with the blind hole to fix the length of the telescopic bracket for a second time. There will be no obvious shaking or displacement during telescopic movement. It can provide stable support when used in different outdoor terrains.

[0021] 2. The guide slider of this utility model is fixed with screws. When the inner rod slides up and down, the guide slider is not easy to fall off or loosen, thereby avoiding accidental contact and friction between the inner rod and the outer rod or the shaking of the inner rod. In addition, the inner diameter of the connecting hole on the guide slider is smaller than the outer diameter of the thread. When adjusting the extension and retraction, the thread can be limited to prevent the thread from accidentally separating from the inner rod when the extension and retraction is too large.

[0022] 3. The ball bearings and guide sliders in this utility model reduce the friction between the inner and outer rods during use, making the inner rod move more smoothly during extension and retraction, and greatly improving the service life of the telescopic bracket.

[0023] 4. This utility model has a simple structure, is easy to operate and learn. When camping, travelers do not need to perform complicated operations after arriving at the rest area, saving physical strength and time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Specific Implementation

[0037] As attached Figures 1-9 As shown: A telescopic tent frame, comprising:

[0038] Outer rod 1, which is cylindrical, has a first screw hole 11 on its wall;

[0039] The connecting pipe 3 is cylindrical. The inner wall of the connecting pipe 3 has a receiving groove 31 from the inside to the outside. The connecting pipe 3 has a through hole 33 on its wall, which is corresponding to the receiving groove 31. A second screw hole 32 is provided on the side of the connecting pipe 3 near the receiving groove 31. A positioning post 34 is fixedly connected to the bottom of the receiving groove 3. A spring 362 is sleeved on the positioning post 34. The bottom end of the connecting pipe 3 is sleeved on the top end of the outer rod 1 and connected by screws through the first threaded hole 11 and the second threaded hole 32.

[0040] The inner rod 2 is cylindrical. A third screw hole 23 and a blind hole 24 are sequentially provided on the inner rod 2 wall from bottom to top. The inner rod 2 has a threaded inner wall 26. The bottom of the inner rod 2 is fixedly connected to a guide slider 21 by a screw through the third threaded hole 23. The bottom of the guide slider 21 has a connecting hole 25. The top of the inner rod 2 has a plug 22. The top of the connecting tube 3 is sleeved on the bottom of the inner rod 2.

[0041] Telescopic device 5, the bottom end of telescopic device 5 is fixedly connected to the inner bottom end of outer rod 1, and the top end of telescopic device 5 passes through connecting hole 25 and is threadedly connected to threaded inner wall 26.

[0042] According to the above technical solution, the present invention can achieve at least the following technical effects: The telescopic device 5 can push the inner rod 2 away from the outer rod 1, or the telescopic device 5 can cause the inner rod 2 to retract towards the outer rod 1. This allows for easy adjustment to a suitable height at different camping locations. Furthermore, the connecting pipe 3 provides secondary reinforcement to the telescopic support's telescopic position, making it more stable during use. The installation of the guide slider 21 and sliding protrusion 35 makes the telescopic movement of the inner rod 2 smoother, while reducing friction between the inner rod 2 and the outer rod 1, thus increasing the service life of the telescopic support. The guide slider 21 is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction, greatly reducing friction with the outer rod and preventing instability caused by deformation of the inner rod 2 and outer rod 1 after friction damage. In addition, it has excellent chemical stability and resistance to high and low temperatures, ensuring it remains unaffected by ambient temperatures during outdoor camping.

[0043] In this embodiment, the pressing component 36 includes a pressing member 361 and a limiting post 363. The pressing member 361 is annular, with one end passing through the through hole 33 and the other end having a groove that fits against the spring 362. The limiting post 363 is fixedly connected to the inner wall of the pressing member 361 near the end of the spring 362.

[0044] According to the above technical solution, the present invention can achieve at least the following technical effects: by setting up a pressing component 36, the limiting post 363 engages with the blind hole 24 on the inner rod 2 when it is extended to the maximum extent, which can fix the position of the telescopic bracket for a second time, making it more stable during use. When not in use, press the top of the pressing component 361 first, and then control the electric telescopic device 5 to retract or manually operate the telescopic mechanism to prevent the electric telescopic device 5 from being accidentally operated and causing it to retract during use.

[0045] In this embodiment, the end of the pressing member 361 away from the spring 362 is provided with a corrugated surface.

[0046] According to the above technical solution, the present invention can achieve at least the following technical effects: the corrugated surface can increase the friction between the finger and the pressing part, and when the pressing part 361 is pressed to retract, the position of the pressing part 361 can be sensed by touch alone, so as to retract and store more quickly.

[0047] In this embodiment, the diameter of the blind hole 24 is the same as the outer diameter of the limiting post 363.

[0048] According to the above technical solution, the present invention can achieve at least the following technical effects: it facilitates the engagement of the limiting post 363 with the blind hole 24, making the telescopic bracket more stable during use and preventing the telescopic bracket from accidentally retracting.

[0049] In this embodiment, the telescopic device 5 includes a motor 51 and a rotating shaft 52. The bottom end of the motor 51 is fixedly connected to the inner bottom end of the outer rod 1, and the output end of the motor 51 is fixedly connected to the bottom end of the rotating shaft 52. The top end of the rotating shaft 52 is provided with a thread 521, and the top end of the rotating shaft 52 passes through the connecting hole 25. The thread 521 is threadedly connected to the inner wall 26 of the thread.

[0050] According to the above technical solution, the present invention can achieve at least the following technical effects: the use of electric power can greatly save manpower and time, reduce the shaking and impact caused by uneven force during manual stretching, and the telescopic device 5 can help protect the internal transmission structure, reduce wear, and extend the overall service life of the telescopic bracket.

[0051] In this embodiment, the diameter of the connecting hole 25 is smaller than the outer diameter of the thread 521, the outer diameter of the inner rod 2 is smaller than the inner diameter of the outer rod 1, and the outer diameter of the guide slider 21 is the same as the inner diameter of the outer rod 1.

[0052] According to the above technical solution, the present invention can achieve at least the following technical effects: the connecting hole 25 is smaller than the outer diameter of the thread 521, which prevents the thread 521 from falling out of the inner rod 2 when it is extended; the outer diameter of the inner rod 2 is smaller than the inner diameter of the outer rod 1, and the outer diameter of the guide slider 21 is similar to the inner diameter of the outer rod 1, which makes the inner and outer rods 1 more stable without contacting or rubbing against each other.

[0053] In this embodiment, a sliding protrusion 35 is fixedly connected to the inner wall of the connecting pipe 3. A strip groove 4 is provided on the sliding protrusion 35, and a plurality of balls 41 are provided in the strip groove 4 to reduce friction when the inner rod extends or retracts.

[0054] According to the above technical solution, the present invention can achieve at least the following technical effects: the ball bearing 41 can make the inner rod more smooth during extension and retraction, and can also reduce the coefficient of friction, so that the inner rod can extend its service life without shaking.

[0055] In this embodiment, the outer rod 1 and the inner rod 2 are made of aluminum alloy. The outer rod 1 and the guide slider 21 are "D" shaped tubes, and the inner rod 2 can be a "D" shaped tube or a pipe with one side recessed inward.

[0056] According to the above technical solution, the present invention can achieve at least the following technical effects: the use of aluminum alloy material makes the overall weight of the telescopic bracket lighter, making it easier to carry, install and operate. It is easier and more convenient to use in outdoor camping where frequent movement or position adjustment is required. In addition, the multiple shapes of the outer rod 1 and inner rod 2 can restrict each other's degree of rotation freedom, prevent telescopic movement and swaying during use, and make the telescopic bracket more stable in the extended state.

[0057] The working principle of this utility model for a telescopic tent support is as follows: Before use, check that all components are intact and functioning properly. The device has both manual and electric telescopic adjustment modes. In manual telescopic adjustment, rotate the inner rod 2 to adjust the telescopic length. At the maximum length, when the limiting post 363 meets the blind hole 24, the spring 362, due to its elasticity, engages the limiting post 363 in the blind hole 24, thus fixing the telescopic support length. After use, directly rotate the inner rod 2 or first press the pressing piece 361 and then manually rotate the inner rod 2 to retract it towards the outer rod 1. In electric telescopic adjustment, turn on the motor 51, causing the thread 521 to rotate, pushing the inner rod 2 away from the outer rod 1. When the telescopic support reaches the appropriate length, the motor 51 can be turned off, the thread 521 stops rotating, and the length of the telescopic support is fixed. Alternatively, the inner rod 2 can continue to move away from the outer rod 1 until the limiting post 363 meets the blind hole 24. The spring 362 will then lock the limiting post 363 into the blind hole 24 due to its elasticity, and the telescopic support will be fixed in length. After use, the motor 51 can be directly controlled to rotate the thread 521 in the opposite direction, causing the inner rod 2 to retract towards the outer rod 1. Alternatively, the pressing part 361 can be pressed and then the motor 51 can be controlled to rotate the thread 521 in the opposite direction, causing the inner rod 2 to retract towards the outer rod 1. In addition, manual operation and electric telescopic operation steps can be interspersed and used in combination.
