Description

Technical Field

[0001] This utility model relates to the field of tent frame technology, specifically a modular tent frame. Background Technology

[0002] A modular tent frame is a support system assembled from detachable and combinable components. It is used to support the tent fabric, forming a sheltered structure with a certain space and shape.

[0003] For example, an existing Chinese patent (CN214835279U) discloses a simple folding travel tent, including a tent base, supporting components, and a tent fabric. The tent fabric covers the supporting components, and the sides of the supporting components are movably connected to the base. The supporting components include multiple supporting rods, with a base hinged to the end of each supporting rod. The base is fixedly connected to the tent base. The supporting rods fold together using the base, causing the tent fabric to fold or unfold. Each supporting rod can be further folded by bending. This utility model provides a simple folding travel tent where each supporting rod consists of two support rods. A supporting head is connected to the middle of the two support rods and is hinged to it, allowing them to fold together. The ends of the two support rods are hinged to the base via pivots, with the hinge points arranged alternately, thus allowing for further folding and reduction of the tent frame for easy carrying during travel.

[0004] In the above-mentioned technical solution, the pivot enables the support pole to flip, thereby allowing the tent to be folded up or unfolded. However, the tent support pole frame is difficult to disassemble from the base, making it difficult to maintain or replace parts of the tent frame individually. On the other hand, this solution lacks a flexible length adjustment mechanism, making it difficult to adapt the tent length to actual usage needs, such as different site sizes and the number of users. This, to some extent, limits the tent's versatility and practicality. Utility Model Content

[0005] The purpose of this invention is to provide a modular tent frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular tent frame, comprising: a U-shaped support rod and a base plate; T-shaped grooves are provided on both sides of the top of the base plate; fan-shaped shells are provided on both sides above the T-shaped grooves; a top fixing support rod is provided on one side of the top of the fan-shaped shell; a central pivot is provided at the center of the fan-shaped shell; a bottom rotating support rod is provided on one side of the outer wall of the central pivot; a connecting shaft is provided between the two sides of the fan-shaped shell; a connecting support rod is provided on one side of the outer wall of the connecting shaft; a pole sleeve is fixed at one end of each connecting support rod, bottom rotating support rod, and top fixing support rod; a U-shaped support rod is provided inside the pole sleeve; and spring pins are provided at both ends of the U-shaped support rod.

[0007] Furthermore, a pin hole is provided on one side of the sleeve to cooperate with the spring pin.

[0010] Furthermore, the bottom end of the fan-shaped shell is provided with a base, which is connected to the T-slot by a T-bolt.

[0011] Furthermore, a pad is provided on the inner wall of the bottom of the fan-shaped shell below the bottom rotating support rod, and a groove is provided on the top surface of the pad that matches the outer wall of the bottom rotating support rod.

[0012] Furthermore, a damping pivot is provided in the middle of the base plate, and the two sector-shaped shells are located on both sides of the damping pivot.

[0013] Furthermore, the sleeve and the U-shaped support rod are interference fit.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, through the design of a U-shaped support rod, a fan-shaped shell, and a T-shaped groove, enables the U-shaped support rod to be connected to the pole sleeve via a spring pin during tent frame use. This facilitates the disassembly and installation of the U-shaped support rod and makes it easier to repair and replace it.

[0016] When assembling the tent, the fan-shaped shells are connected to the base plate by T-bolts, which allows the spacing between the two fan-shaped shells to be adjusted, thereby adjusting the length of the entire tent frame. Combined with the elastic design at the top of the tent fabric or the zipper-type telescopic design, the length of the tent can be adjusted.

[0017] When setting up the tent, first open the middle section, then rotate the bottom rotating support rod to align it with the padding block, flattening both ends of the tent. Finally, manually tie the U-shaped support rod in the middle of the tent to the straps on the tent fabric to secure it, thus unfolding the tent. When you need to pack up the tent, simply rotate the bottom rotating support rod towards the top fixed support rod to pack it up quickly and easily.

[0025] 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a modular tent frame, including: a U-shaped support rod 1 and a base plate 3. The U-shaped support rod 1 serves as the main support structure of the tent, and the base plate 3 provides a stable foundation for the tent, ensuring the stability and safety of the tent.

[0027] The base plate 3 has T-slots 4 on both sides of its top, and fan-shaped shells 6 on both sides above the T-slots 4. The design of the T-slots 4 provides a positioning and fixing foundation for the installation of the fan-shaped shells 6, making it easy for the fan-shaped shells 6 to be connected to the base plate 3 by T-bolts. The connection is stable, and disassembly and distance adjustment are convenient. A top fixing support rod 8 is provided on one side of the top of the fan-shaped shell 6. The top fixing support rod 8 is fixedly set on one side of the fan-shaped shell 6 to provide a positioning mark for the unfolding or folding of the tent. When unfolded, the bottom rotating support rod 9 moves away from the top fixing support rod 8, and when folded, the bottom rotating support rod 9 moves closer to the top fixing support rod 8.

[0028] A central pivot 7 is located at the center of the fan-shaped shell 6, and a bottom rotating support rod 9 is located on one side of the outer wall of the central pivot 7. The design of the central pivot 7 and the bottom rotating support rod 9 allows the tent frame to rotate flexibly during unfolding and folding, facilitating operation. The bottom rotating support rod 9 supports one end of the tent when it is unfolded, ensuring the tent is flat and stable. A connecting shaft 12 is located between the two sides of the fan-shaped shell 6, and a connecting support rod 13 is located on one side of the outer wall of the connecting shaft 12. The connecting shaft 12 and the connecting support rod 13 enhance the overall structural strength of the tent frame, allowing the tent to better distribute and withstand pressure when subjected to external forces, thus improving the tent's durability and stability.

[0029] Each of the connecting support rod 13, the bottom rotating support rod 9, and the top fixed support rod 8 has a pole sleeve 11 fixed to one end. A U-shaped support rod 1 is installed inside the pole sleeve 11, and spring pins 2 are installed at both ends of the U-shaped support rod 1. The design of the pole sleeve 11 allows the U-shaped support rod 1 to be easily connected to the connecting support rod 13, the bottom rotating support rod 9, and the top fixed support rod 8. This connection method is both stable and easy to disassemble, facilitating tent assembly and adjustment. The spring pins 2 allow the U-shaped support rod 1 to be quickly and securely connected or separated from the pole sleeve 11, simplifying the installation and disassembly process and improving tent assembly efficiency.

[0030] A pin hole is provided on one side of the pole sleeve 11 to mate with the spring pin 2. The design of the pin hole ensures that the spring pin 2 can be accurately inserted into the pole sleeve 11, realizing a stable connection between the U-shaped support pole 1 and the pole sleeve 11, and improving the stability and safety of the tent. The pole sleeve 11 and the U-shaped support pole 1 are interference-fitted, which increases the connection strength between the pole sleeve 11 and the U-shaped support pole 1.

[0031] There are multiple connecting shafts 12, located between the top fixed support rod 8 and the bottom rotating support rod 9, and arranged at equal angles on the sector-shaped shell 6. The connecting shafts 12 are rotatably connected to the sector-shaped shell 6, rotating as the tent unfolds or is stowed. The equal-angle arrangement of the multiple connecting shafts 12 ensures that the tent frame forms a uniform support structure when unfolded, improving the tent's stability and load-bearing capacity.

[0032] The fan-shaped shell 6 has arc-shaped grooves 14 on both sides, which are located at both ends of the connecting shaft 12. The connecting shaft 12 can slide within the arc-shaped grooves 14. At this time, the connecting shaft 12 can rotate on the fan-shaped shell 6 and slide within the arc-shaped grooves 14. When the tent is unfolded or folded up, the connecting shaft 12 rotates and comes together with the U-shaped rod 1.

[0033] The bottom of the fan-shaped shell 6 is equipped with a base 5, which is connected to the T-slot 4 by T-bolts. The design of the base 5 provides stable support for the fan-shaped shell 6, and the connection to the T-slot 4 by T-bolts allows for easy adjustment of the spacing of the fan-shaped shell 6, facilitating the adjustment of the tent length. A pad 10 is located on the inner wall of the bottom of the fan-shaped shell 6 below the bottom rotating support rod 9. The top surface of the pad 10 has a groove that matches the outer wall of the bottom rotating support rod 9. The design of the pad 10 and the groove ensures that the bottom rotating support rod 9 can be accurately placed on the pad 10 when the tent is deployed, improving the stability and flatness of the tent. At the same time, the pad 10 also acts as a buffer, reducing the collision between the bottom rotating support rod 9 and the fan-shaped shell 6.

[0034] A damping pivot 15 is located in the center of the base plate 3, with two fan-shaped shells 6 located on either side of the damping pivot 15. The base plate 3 is designed to be foldable, allowing the tent components on both sides to fit together more tightly when the tent is packed away. The finally packed tent is secured together with ropes to prevent it from coming apart.

[0035] When the tent frame is in use, the U-shaped support rod 1 is connected to the pole sleeve 11 by a spring pin 2, which facilitates the disassembly and installation of the U-shaped support rod 1 and makes it easy to repair and replace the U-shaped support rod 1.

[0036] During tent assembly, the fan-shaped shell 6 is connected to the base plate 3 by T-bolts, which can adjust the distance between the two fan-shaped shells 6, thereby adjusting the length of the entire tent frame. Combined with the elastic design at the top of the tent fabric or the zipper telescopic design, the length of the tent can be adjusted.

[0037] When the tent is set up, the middle part of the tent is set up first. Then, the bottom rotating support rod 9 is rotated to fit with the pad 10, so that both ends of the tent are flattened. Finally, the U-shaped support rod 1 in the middle of the tent is manually tied to the straps on the tent fabric to set up the tent. When the tent needs to be packed away, simply rotate the bottom rotating support rod 9 towards the top fixed support rod 8 to pack the tent away. It is convenient and quick.

[0038] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
