Description

Technical Field

[0001] This utility model relates to the field of tent supplies technology, and in particular to a tent frame with a novel switch. Background Technology

[0002] Existing tent frames mostly employ traditional mechanical locking or sliding rail opening and closing mechanisms. These mechanisms are prone to problems such as loosening of the locking mechanisms and jamming of the sliding rails due to friction wear, structural fatigue, or uneven stress distribution during long-term use, affecting the stability and lifespan of the tent frame. Furthermore, some opening and closing mechanisms are susceptible to deformation due to unreasonable structural design when subjected to heavy loads or frequent opening and closing, thus affecting the overall support performance of the tent. Therefore, existing technologies still suffer from problems such as insufficient smoothness of opening and closing, inadequate durability, and uneven stress distribution, requiring urgent improvement.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment, refer to Figures 1 to 6A novel tent frame with a switch includes a canopy frame 1, a main movable frame 2, and a main beam 3. A triangular roller switch device 4 is installed inside the main beam 3. The triangular roller switch device 4 includes two half-shells 5, two inclined pressure locks 6, two triangular rollers 7, and an opening / closing device 8. Each half-shell 5 is semi-cylindrical and has a central movable area 9 for placing the triangular rollers 7. The bottom center of the movable area 9 has mounting holes 10 corresponding to the triangular rollers 7. Each end of the half-shell 5 has a connecting seat groove 11, and the groove wall of the connecting seat groove 11 is evenly provided with latches 12 and latch holes 13. The inclined pressure locks 6 are semi-cylindrical and inclined... The pressure lock 6 has a push block 14 in the center; the bottom of the push block 14 has a second buckle 15 and a second buckle hole 16; the two ends of the angled pressure lock 6 are respectively provided with connecting seats 17, and the connecting seats 17 are provided with a third buckle 18 and a third buckle hole 19; the triangular roller 7 is triangular in shape, and the bottom center of the triangular roller 7 is provided with a locking foot 20; the opening and closing device 8 is an inverted T-shaped part, and the opening and closing device 8 is provided with an inverted T-shaped base 21, a control handle 22 and a connecting rod 23; the control handle 22 is horizontally arranged on the inverted T-shaped base 21, and the control handle 22 is connected to the connecting rod 23; the top of the connecting rod 23 is provided with a connecting hole 24 for connecting with the angled pressure lock 6.

[0025] In a preferred embodiment of this utility model, the inclined pressure lock 6 is installed inside the half-shell 5, forming a stable support structure with the half-shell 5 to ensure the reliability of the overall opening and closing device. The triangular roller 7 is located in the center between the inclined pressure lock 6 and the half-shell 5, utilizing its rolling characteristics to reduce sliding friction, making the opening and closing process of the tent frame smoother and more stable. The triangular roller 7 is connected to the center of the half-shell 5 through the locking foot 20, and can maintain stable rotation under stress, avoiding shaking or falling off, improving durability and service life. The two half-shells 5 are symmetrically snapped together, and achieve a tight fit with the cooperation of the locking buckle 12 and the locking hole 13, ensuring the overall stability of the device, while improving the convenience of assembly and disassembly. The bottom of the inclined pressure lock 6 is connected to the connecting rod 23. One end of the connecting rod 23 passes through the inclined pressure lock 6 and is connected to the control handle 22 of the opening and closing device 8, allowing the user to flexibly adjust the state of the inclined pressure lock 6 through the control handle 22, thereby achieving precise control of the triangular roller 7 and improving the efficiency and stability of the opening and closing operation of the tent frame.

[0026] In a preferred embodiment of this utility model, both ends of the semi-shell 5 are fixedly connected to the interior of the main beam 3, and the stability of the connection is ensured by a snap-fit ​​structure or bolt fasteners, thereby improving the load-bearing capacity and durability of the overall frame and preventing loosening or displacement due to long-term use. The structural design of the semi-shell 5 can effectively match the internal shape of the main beam 3, so that it forms an integrated support with the main beam 3 after installation, improving the rigidity and deformation resistance of the overall frame. The main beam 3 has an opening at the position corresponding to the triangular roller switch device 4. The shape and size of the opening match the contour of the triangular roller 7 to ensure that the triangular roller 7 can extend and retract smoothly without affecting its rotation and locking functions. One corner of the triangular roller 7 extends to the outside of the main beam 3 through the opening to form a latch. During the opening and closing process, when the triangular roller 7 rotates to a specific angle, its exposed part can engage with the external structure to achieve a stable lock, preventing the tent frame from accidentally retracting or unfolding under stress, and improving the safety and stability of use.

[0027] In a preferred embodiment of this utility model, the canopy frame 1 includes a T-shaped support 25 and a tent pole. The top of the T-shaped support 25 is symmetrically provided with U-shaped connecting grooves 26. The size and shape of the U-shaped connecting grooves 26 are optimized to accommodate tent poles of different specifications, ensuring the tent poles are securely embedded and maintain good support under load, preventing wobbling or detachment. The interior of the U-shaped connecting grooves 26 may also be provided with anti-slip pads or limiting protrusions to enhance the fixing effect and improve the overall structural stability. The bottom of the T-shaped support 25 is provided with a main beam connecting seat 27, which is connected to the main beam 3 by a snap-fit ​​or bolt fastening method, ensuring that the T-shaped support 25 is securely fixed to the top of the main beam 3. The T-shaped support 25 is placed on top of the main beam 3, and a limiting block 32 is provided between the tent pole and the main beam 3. The limiting block 32 provides additional support and limiting functions, ensuring that the tent pole maintains a stable supporting state after deployment. The shape and size of the limiting block 32 are optimized to accommodate the opening and closing angles of the tent top pole at different angles, and to provide additional support when the tent top pole is subjected to wind or other external loads, preventing abnormal swaying or structural instability of the tent frame. Furthermore, the limiting block 32 can be made of high-strength, wear-resistant materials to improve durability and extend the service life of the tent frame.

[0028] In a preferred embodiment of this utility model, the main movable frame 2 includes a sliding support 28 and tent poles. The sliding support 28 has an inverted T-shaped cross-section, and a main beam mounting seat 29 is provided on the top of the sliding support 28. The main beam mounting seat 29 is precision machined to match the main beam 3 to improve the connection stability and durability of the components. A locking hole 30 is provided on the main beam mounting seat 29, which is used to precisely cooperate with the triangular roller switch device 4 to provide necessary limiting and locking functions during the opening and closing of the tent frame. The shape and position of the locking hole 30 are optimized to adapt to tent frames of different specifications, ensuring the flexibility and compatibility of the opening and closing mechanism. The bottom of the sliding support 28 is designed with staggered vertically distributed U-shaped mounting grooves 31. The main movable frame 2 is fitted onto the main beam 3 through the sliding support 28, and the smooth opening and closing of the tent frame is achieved by the mutual cooperation between the locking hole 30 on the main beam mounting seat 29 and the triangular roller switch device 4 inside the main beam 3. When the tent frame is deployed or retracted, the rolling structure of the triangular roller switch device 4 allows the sliding support 28 to slide smoothly along the main beam 3. Simultaneously, the locking hole 30 precisely engages with the locking mechanism of the triangular roller 7, providing stable support after deployment and smooth reset during retraction. This structural design not only improves the service life of the tent frame but also enhances operational convenience and safety, ensuring stable performance in various application scenarios.

[0029] In a preferred embodiment of this utility model, the tent top pole and the tent pole are hinged together by a connector.

[0030] This invention employs an embedded triangular roller switch device 4 to achieve smooth opening and closing and stable locking of the tent frame. The main movable frame 2 slides on the main beam 3 via a sliding support 28. The main beam mounting base 29 of the sliding support 28 has a locking hole 30, which cooperates with the triangular roller switch device 4 inside the main beam 3 to achieve precise locking when the tent frame is unfolded and retracted. The triangular roller switch device 4 consists of a half-shell 5, a slanted lock 6, a triangular roller 7, and an opening / closing device 8. The half-shell 5 is fixed inside the main beam 3, and the triangular roller 7 is located in the movable area 9 of the half-shell 5 and is installed via a locking foot 20. The main beam 3 has an opening at a corresponding position, through which the triangular roller 7 can form an external lock when it rotates. The slanted lock 6 is connected to the opening / closing device 8. When the user operates the control handle 22 of the opening / closing device 8, the slanted lock 6 pushes the triangular roller 7 to rotate via a connecting rod 23, causing it to enter or exit the opening of the main beam 3, thereby completing the locking or releasing of the tent frame. In the unfolded state, the triangular roller 7 engages with and locks into the opening of the main beam 3, ensuring stable support for the tent frame. In the folded state, the user operates the opening / closing mechanism 8, and the inclined locking mechanism 6 disengages the triangular roller 7, allowing the sliding support 28 to slide along the main beam 3, thus enabling rapid folding of the tent frame. This design reduces frictional wear, improves the smoothness of opening and closing, and enhances the durability and safety of the tent frame.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
