Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment, and in particular to a four-corner tent support and fixing frame. Background Technology

[0002] Four-corner tent support frame is mainly used for setting up four-corner tents in outdoor camping, leisure picnics, emergency rescue and disaster relief and outdoor activities. It is widely used in the outdoor equipment industry. Its core function is to support the main frame of the tent and maintain the stability of the tent structure. At the same time, it can adapt to different ground environments to achieve height adjustment and wind and slip resistance, ensuring the safety of tent use.

[0003] Currently, the four-corner tent support frame on the market is mainly composed of multi-section telescopic legs, right-angle connectors, and ground stakes and rope components. It mainly adjusts the tent height by telescopic legs, reinforces the corner structure by connectors, and grips the ground with the support feet, so as to achieve the effect of stable tent setup and easy storage and carrying.

[0004] Existing four-corner tent support brackets have varying degrees of effectiveness in securing tents in different environments. For example, the brackets suitable for use on muddy ground are not suitable for use on concrete ground, and vice versa. Furthermore, the large cross-sectional area of ​​the tent can easily cause instability in strong winds. Therefore, a new four-corner tent support bracket is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a four-corner tent support and fixing frame, which aims to improve the problem of poor environmental adaptability of the four-corner tent support and fixing frame.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a four-corner tent support frame, comprising four support rods, a buffer tube slidably connected to the top outer side of each support rod, multiple fixing rings fixedly connected to the outer side of the buffer tube, a canopy bracket fixedly connected to the outside of each fixing ring, two circular grooves opened inside the bottom side of each support rod, two locking grooves opened on the inner wall of each circular groove, a first abutment plate slidably connected inside each circular groove, two locking tongues fixedly connected to one side of the first abutment plate, a linkage column fixedly connected to the other side of the locking tongues, a spring sleeved on the outside of the linkage column, a support plate fixedly connected to the end of the linkage column away from the first abutment plate, an anti-slip pad fixedly connected to one side of the support plate, and four fixing spikes fixedly connected to the other side of the support plate.

[0007] As a further description of the above technical solution:

[0008] A second abutment is fixedly connected to the top of the support rod, a third spring is fixedly connected to the top of the second abutment, and the second spring is sleeved on the outside of the support rod.

[0009] As a further description of the above technical solution:

[0010] The abutment is rotatably connected to the inner wall of the circular groove.

[0011] As a further description of the above technical solution:

[0012] The latch is inserted into the inner wall of the lock groove.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the outside of the abutment plate, and the other end of the spring is fixedly connected to the inner wall of the circular groove.

[0015] As a further description of the above technical solution:

[0016] The end of the spring three away from the abutment two is fixedly connected to the inner wall of the buffer tube.

[0017] As a further description of the above technical solution:

[0018] One end of the second spring is fixedly connected to the bottom of the second abutment, and the other end of the second spring is fixedly connected to the inner wall of the buffer tube.

[0019] As a further description of the above technical solution:

[0020] The two adjacent anti-slip pads are symmetrically distributed.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pulling the support plate, the linkage component is driven to disengage the lock tongue from the lock groove. Then, the support plate is rotated to adjust the orientation of the support plate. When the side with the fixed spikes faces down, the spikes can be inserted into the mud to enhance the grip. When the side with the anti-slip pads faces down, the anti-slip pads can increase the friction with the cement ground. After adjustment, the lock tongue is pushed to lock the position by the spring return force. There is no need to replace the extra foot support component, which can meet the fixing needs of different ground surfaces such as mud and cement, and improve the convenience and adaptability of use.

[0023] 2. In this utility model, the top buffer tube can slide along the support rod. When the wind causes the buffer tube to move upward, the top spring is compressed to generate a reverse elastic force. When the buffer tube moves downward, the outer spring is stretched to generate a reverse pulling force. The two cancel out the impact displacement. At the same time, the canopy bracket is connected to the buffer tube through the fixing ring, which can evenly distribute the wind force to each support rod, avoid unilateral sliding and tilting, and effectively solve the problem of strong wind instability caused by the large cross-sectional area of ​​the tent.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-4This utility model provides an embodiment of a four-corner tent support frame, comprising four support rods 1, each corresponding to one of the four corners of the tent, providing stable vertical support for the entire tent and laying the foundation for subsequent adaptation to different ground surfaces and wind-resistant structures. A buffer tube 2 is slidably connected to the outer top of each support rod 1, allowing the buffer tube 2 to slide up and down along the outer top of the support rod 1. With the subsequent use of a spring component, it can absorb displacement caused by wind or external impact, reducing the rigid stress on the support rod 1 and the canopy support 4, thus improving overall wind resistance. Multiple fixing rings 3 are fixedly connected to the outer side of the buffer tube 2, and the canopy support 4 is fixedly connected to the outside of the fixing rings 3. The canopy support 4 forms a stable structure with the buffer tube 2 through the fixing rings 3, allowing the tent canopy to be stretched. The force and wind force are distributed to the four support rods 1, enhancing wind resistance stability. Two circular grooves 5 are symmetrically arranged inside the bottom side of each support rod 1. Two locking grooves 6 are formed on the inner wall of each groove 5, corresponding to the subsequent locking tongues 8. The locking tongues 8 and locking grooves 6 work together to lock the position of the abutment plate 7 within the groove 5, ensuring the stability of the bottom support structure when used on different ground surfaces. The abutment plate 7 is slidably connected inside the groove 5, allowing it to slide axially within the groove 5, causing the locking tongues 8 and the linkage column 9 to move synchronously. This adapts to different needs, such as needing deep fixation on muddy ground and needing stable contact on concrete ground. Two locking tongues 8 are fixedly connected to one side of the abutment plate 7, matching the locking grooves 6 on the inner wall of the groove 5. The latch 8 can slide into or out of the locking groove 6 with the abutment plate 7, realizing the locking and unlocking of the bottom support structure, ensuring that it can be stably fixed in the required position after adjustment. A linkage column 9 is fixedly connected to the other side of the latch 8. The linkage column 9 connects the latch 8 and the support plate 14 into a whole. A spring 10 is sleeved on the outside of the linkage column 9. The spring 10 can generate elastic deformation when the linkage column 9 drives the latch 8 to move. When the latch 8 is aligned with the locking groove 6, the restoring force of the spring 10 can push the latch 8 to automatically lock into the locking groove 6 and maintain the locked state. The end of the linkage column 9 away from the abutment plate 7 is fixedly connected to the support plate 14. The support plate 14 is the direct part of the support rod 1 in contact with the ground, which can increase the contact area between the support rod 1 and the ground and prevent it from sinking into the mud when used on muddy ground. On one side of the support plate 14, an anti-slip pad 15 is fixedly connected. When used on hard surfaces such as cement, the anti-slip pad 15 can enhance the friction between the support plate 14 and the ground, preventing the support pole 1 from sliding under the action of wind and ensuring the stability of the tent on hard surfaces. On the other side of the support plate 14, four fixing spikes 16 are fixedly connected. When used on soft surfaces such as mud, the four fixing spikes 16 can be inserted into the soil to enhance the grip of the bottom, prevent the fixing frame from shifting under the action of wind, and improve the wind resistance in soft ground environments. Pull the support plate 14 to pull the locking tongue 8 out of the locking groove 6. Rotate the support plate 14 to select a suitable surface to contact the ground. After selection, release the support plate 14. The spring 10 pushes the abutment plate 7 to drive the locking tongue 8 into the locking groove 6.

[0034] Reference Figures 5-6 A second abutment plate 11 is fixedly connected to the top of the support rod 1. The second abutment plate 11 is fixed to the top of the support rod 1, providing a stable mounting support point for the second spring 12 and the third spring 13, ensuring that the two springs can work together to buffer the wind. The third spring 13 is fixedly connected to the top of the second abutment plate 11 and is located between the second abutment plate 11 and the inner wall of the buffer tube 2. When the buffer tube 2 moves upward under the wind force, the third spring 13 can be compressed and generate a reverse elastic force to offset part of the impact force and reduce the upward displacement of the canopy support 4. The second spring 12 is sleeved on the outside of the support rod 1. The second spring 12 is wrapped around the outside of the support rod 1 and is located between the second abutment plate 11 and the inner wall of the buffer tube 2. When the buffer tube 2 moves downward under the wind force, the second spring 12 can be stretched and generate a reverse pulling force, which, together with the third spring 13, forms a two-way buffer to further improve the wind resistance effect. Figure 4 The abutment plate 7 is rotatably connected to the inner wall of the circular groove 5. The abutment plate 7 can not only slide but also rotate on the inner wall of the circular groove 5, which facilitates the adjustment of the alignment angle between the locking tongue 8 and the locking groove 6, ensuring that the locking tongue 8 can be stably locked into the locking groove 6, and adapting to complex ground environments.

[0035] Reference Figure 4 The locking tongue 8 is inserted into the inner wall of the locking groove 6. The insertion structure ensures that the locking tongue 8 and the locking groove 6 fit tightly together, preventing loosening or separation under wind vibration and ensuring the locking stability of the bottom support structure.

[0036] Reference Figure 4 One end of the spring 10 is fixedly connected to the outside of the abutment plate 7, and the other end of the spring 10 is fixedly connected to the inner wall of the circular groove 5. This method of fixing at both ends allows the spring 10 to continuously provide elastic force to the abutment plate 7, ensuring that the locking tongue 8 is always tightly engaged in the locking groove 6 and maintaining the stability of the bottom structure.

[0037] Reference Figure 6 The end of spring 3 13 away from the abutment plate 2 11 is fixedly connected to the inner wall of the buffer tube 2, so that when the buffer tube 2 slides along the support rod 1, it can directly drive the spring 3 13 to deform, quickly respond to external force impact, absorb the displacement generated by wind force in time, and improve the timeliness of wind resistance and buffering.

[0038] Reference Figure 6 One end of spring 12 is fixedly connected to the bottom of the abutment plate 11, and the other end of spring 12 is fixedly connected to the inner wall of the buffer tube 2, forming a symmetrical buffer structure with spring 13. This constrains the sliding range of the buffer tube 2 from two directions, further reducing the impact of wind on the support rod 1 and the roof.

[0039] Reference Figure 3The two adjacent anti-slip pads 15 are symmetrically distributed. The symmetrical distribution of the anti-slip pads 15 can ensure that the bottom of the two adjacent support poles 1 is evenly stressed. When used on hard surfaces such as cement, the friction can be increased simultaneously from both sides to avoid sliding on one side and causing the tent to tilt, thus maintaining the overall structural balance.

[0040] Working Principle: First, four support rods 1 provide stable vertical support at the four corners of the tent. Then, the bottom structure needs to be adjusted according to the ground type. Pull the linkage column 9 away from the support plate 14 connected to the end of the support plate 7. The linkage column 9 drives the support plate 7, which is fixedly connected to the locking tongue 8, to slide within two symmetrically opened circular grooves 5 on the bottom side of the support rod 1. This causes the two locking tongues 8 fixed on one side of the support plate 7 to be pulled out from the two locking slots 6 opened on the inner wall of the circular groove 5. Because the support plate 7 is rotatably connected to the inner wall of the circular groove 5, the orientation of the support plate 14 can be adjusted by rotating the support plate 7. When using on muddy ground, the four fixed spikes 16 fixed on the other side of the support plate 14 should face downwards to enhance bottom grip. When using on concrete ground, the anti-slip pads 15 fixed on one side of the support plate 14 should face downwards to increase friction with the ground. After adjustment, release the support plate 14. The spring 10 sleeved on the outside of the linkage column 9 generates a restoring force, pushing the support plate 7 to re-insert the locking tongues 8 into the inner wall of the locking slots 6, achieving stable locking of the bottom support structure. It is slidably connected to the outer top of the support rod 1. The buffer tube 2, with multiple fixing rings 3 fixedly connected to its outer side, securely connects the canopy support 4, allowing the canopy support 4 to evenly distribute the tension of the tent roof and the wind force it bears to the four support rods 1, avoiding excessive local stress. At the same time, the abutment plate 2 11 fixed at the top of the support rod 1 provides a stable installation support point for the spring 2 12 sleeved on the outside of the support rod 1 and the spring 3 13 fixed at the top of the abutment plate 2 11. When the buffer tube 2 moves upward under the wind force, the spring 3 13 is compressed to generate a reverse elastic force to offset part of the impact force and reduce the upward displacement of the canopy support 4. When the buffer tube 2 moves downward under the wind force, the spring 2 12 is stretched to generate a reverse pulling force. The two work together to form a two-way buffer structure, further weakening the impact of wind force on the support rods 1 and the roof. In addition, the two adjacent anti-slip pads 15 are symmetrically distributed, which can ensure that the bottom of the two adjacent support rods 1 is evenly stressed. When used on hard ground such as cement, the friction is enhanced simultaneously to avoid unilateral sliding that causes the tent to tilt. Ultimately, the fixed frame achieves adaptable support and strong wind resistance in different ground environments.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
