[0002] In sports training, such as track and field hurdle training and gymnastics climbing training, obstacle courses are used to simulate competition scenarios and improve athletes' specific skills. In military training, various complex obstacles, such as trenches, low walls, and barbed wire, can be set up to simulate real battlefield environments and improve soldiers' combat skills and environmental adaptability. For fire rescue training, obstacle courses can simulate the complex terrain and obstacles at fire scenes, helping firefighters improve rescue efficiency and their ability to respond to emergencies.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing training obstacle courses lack a foldable structure, making the transportation process extremely cumbersome when the training site needs to be changed. This requires a significant amount of manpower and resources, thereby reducing the flexibility of the training obstacle courses in use.

[0004] To address this, a foldable, multi-site universal training obstacle course is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable multi-site universal training obstacle course, including a base, a folding mechanism fixedly connected to the inner side of the base, a column fixedly connected to the top of the base, the folding mechanism being slidably connected to the inner side of the column, and a fixing mechanism fixedly connected to the surface of the top of the column.

[0007] The folding mechanism includes a connecting tube, an extension rod, a insertion hole, a pin, an inner tube, a crossbar, an extension rod, a movable groove, a return spring, a ball bearing, and a retaining ball groove. The connecting tube is fixedly connected to the right side of the left base, and the extension rod is fixedly connected to the left side of the right base.

The crossbar is fixedly connected to the right side of the top of the left inner tube. The extension rod is fixedly connected to the left side of the top of the right inner tube. The extension rod is slidably connected to the inner side of the crossbar. The movable groove is opened on the right side of the inner wall of the crossbar. The return spring is fixedly connected to the inner side of the movable groove. The ball bearing is movably connected to the inner side of the movable groove. The side of the return spring away from the movable groove contacts the surface of the ball bearing. The retaining ball groove is opened on the left side of the extension rod and engages with the ball bearing.

[0008] The fixing mechanism includes a connecting ring, a rotating groove, a torsion spring, a connecting rod, a snap-fit ​​half-ring, a connecting hole, and a plug-in rod. The connecting ring is fixedly connected to the surface of the top of the column. The rotating groove is formed on both sides of the connecting ring. The torsion spring is fixedly connected to the inner side of the rotating groove. The bottom of the connecting rod is fixedly connected to the surface of the torsion spring.

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides the following technical solution:

[0024] A foldable, multi-site universal training obstacle course includes a base 1, a folding mechanism 2 fixedly connected to the inner side of the base 1, a column 3 fixedly connected to the top of the base 1, the folding mechanism 2 being slidably connected to the inner side of the column 3, and a fixing mechanism 4 fixedly connected to the top surface of the column 3.

[0025] The folding mechanism 2 includes a connecting tube 201, an extension rod 202, a insertion hole 203, a pin 204, an inner tube 205, a crossbar 206, an extension rod 207, a movable groove 208, a return spring 209, a ball bearing 210, and a retaining ball groove 211. The connecting tube 201 is fixedly connected to the right side of the left base 1, and the extension rod 202 is fixedly connected to the left side of the right base 1. The extension rod 202 is slidably connected to the inner side of the connecting tube 201. The insertion holes 203 are respectively opened at the top of the connecting tube 201 and the top of the extension rod 202. The pin 204 is engaged with the inner side of the insertion hole 203. The inner tube 205 is slidably connected to the vertical base 1. Inside column 3, crossbar 206 is fixedly connected to the right side of the top of left inner tube 205, extension rod 207 is fixedly connected to the left side of the top of right inner tube 205, extension rod 207 is slidably connected to the inside of crossbar 206, movable groove 208 is opened on the right side of the inner wall of crossbar 206, return spring 209 is fixedly connected to the inside of movable groove 208, ball 210 is movably connected to the inside of movable groove 208, the side of return spring 209 away from movable groove 208 contacts the surface of ball 210, and ball retaining groove 211 is opened on the left side of extension rod 207, ball retaining groove 211 and ball 210 are engaged.

[0026] In this embodiment: The base 1 provides a stable mounting platform for the folding mechanism 2 and the column 3. The column 3 supports and limits the folding mechanism 2 and the fixing mechanism 4. The sliding connection between the connecting pipe 201 and the extension rod 202, along with the insertion hole 203 and the pin 204, allows for convenient adjustment of the overall width of the obstacle frame. By pulling out the pin 204, sliding the extension rod 202, and then inserting the pin 204 to fix it, the obstacle frame can quickly adapt to the space limitations of different venues and the width requirements of different training programs, improving its versatility and flexibility. It is flexible and easy to operate. The inner tube 205 slides inside the column 3, which can adjust the overall height of the obstacle frame to adapt to the height and training needs of different trainees. The crossbar 206 and the extension bar 207 are telescopic through the cooperation of the ball bearing 210 and the ball locking groove 211 and the action of the return spring 209. When the obstacle length needs to be adjusted, the user slides the extension bar 207 to the position. Under the elastic force of the return spring 209, the ball bearing 210 is locked into the corresponding ball locking groove 211 to prevent shaking or loosening and ensure the safety of the trainees.

[0027] Specifically, such as Figure 4 As shown, the fixing mechanism 4 includes a connecting ring 401, a rotating groove 402, a torsion spring 403, a connecting rod 404, a snap-fit ​​half ring 405, a connecting hole 406, and a plug-in rod 407. The connecting ring 401 is fixedly connected to the surface of the top of the column 3.

[0028] Specifically, such as Figure 4 As shown, the rotating groove 402 is formed on both sides of the connecting ring 401, the torsion spring 403 is fixedly connected to the inner side of the rotating groove 402, the bottom of the connecting rod 404 is fixedly connected to the surface of the torsion spring 403, and the snap-fit ​​half ring 405 is fixedly connected to the top of the connecting rod 404.

[0029] Specifically, such as Figure 4 As shown, the inner wall of the snap-fit ​​half ring 405 is snapped onto the surface of the inner tube 205, and the connecting holes 406 are respectively opened on both sides of the snap-fit ​​half ring 405 and the surface of the inner tube 205. The plug rod 407 is snapped onto the inner side of the connecting hole 406.

[0030] In this embodiment: the fixing mechanism 4 is securely connected to the column 3 by setting a connecting ring 401. The rotating groove 402 provides installation space and rotation track for the torsion spring 403 and the connecting rod 404. The elasticity of the torsion spring 403 enables the connecting rod 404 to drive the locking half ring 405 to have an automatic reset function. When it is necessary to fix the inner tube 205, the locking half ring 405 is rotated to fit the inner tube 205. After it is released, the torsion spring 403 pushes the locking half ring 405 to fit tightly against the inner tube 205, realizing fast and stable fixing, which enhances the overall stability and safety of the obstacle frame. The connecting hole 406 and the plug rod 407 cooperate with each other. After the locking half ring 405 fixes the inner tube 205, the plug rod 407 is further inserted through the connecting hole 406 to reinforce the connection between the locking half ring 405 and the inner tube 205 for a second time, preventing the locking half ring 405 from being accidentally released during use, ensuring that the connection between the inner tube 205 and the column 3 is firm and reliable, and ensuring the safety of the trainees.

[0031] Specifically, such as Figure 5 As shown, the bottom of the base 1 is fitted with an anti-slip rubber pad 5, and the bottom of the anti-slip rubber pad 5 is engraved with anti-slip texture.

[0032] Specifically, such as Figure 2 As shown, a pull ring 6 is fixedly connected to the top of the pin 204, and the surface of the pull ring 6 is engraved with anti-slip texture.

[0033] In this embodiment: by setting the anti-slip rubber pad 5, the obstacle frame can be effectively prevented from sliding during training, ensuring the stability of the obstacle frame. By setting the anti-slip texture, the friction between the obstacle frame and the ground is increased. By setting the pull ring 6, it is convenient for trainees to insert and remove the pin 204. By setting the anti-slip texture, the friction between the hand and the pull ring 6 is increased.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, the crossbar 206 and the extension bar 207 are made of aluminum alloy, and the surfaces of both the crossbar 206 and the extension bar 207 are coated with anti-corrosion paint.

[0035] Specifically, such as Figure 4 As shown, the inner wall of the snap-fit ​​half ring 405 is fitted with a protective pad 7, and the surface of the protective pad 7 is engraved with anti-slip texture.

[0036] In this embodiment: the crossbar 206 and the extension bar 207 are made of aluminum alloy. Aluminum alloy is lightweight and has high strength, which facilitates the handling and installation of the obstacle frame and ensures that the crossbar 206 and the extension bar 207 can withstand the force of the trainees during use without deformation or damage. By applying an anti-corrosion coating, the crossbar 206 and the extension bar 207 can be effectively prevented from being corroded in humid environments or during long-term use, thus extending their service life. By setting a protective pad 7, the fixing of the snap-fit ​​half ring 405 to the inner tube 205 is more stable. By setting an anti-slip texture, the friction between the crossbar 206 and the inner tube 205 is increased.

[0037] Working principle: Before training, the user moves the base 1 of the training obstacle set to the predetermined installation position. Then, the user holds the pull ring 6 at the top of the pin 204 and pulls the pin 204 out of the insertion hole 203. Next, the user pulls the right base 1 to the right. During the movement of the base 1, the extension rod 202 moves to the right synchronously, and the right column 3 also moves to the right. At the same time, the extension rod 207 slides to the right along the crossbar 206. When the extension rod 207 moves, it puts pressure on the ball bearing 210, forcing the ball bearing 210 into the movable groove 208. The extension rod 207 moves to the side, thus compressing the return spring 209. When the ball groove 211 on the left side of the extension rod 207 moves to a position flush with the movable groove 208, the return spring 209 will quickly release its elastic force, causing the ball 210 to pop out and tightly engage with the ball groove 211, thereby keeping the extension rod 207 stably in its current position. At the same time, the insertion hole 203 at the top of the extension rod 202 will also coincide with the insertion hole 203 at the top of the connecting tube 201. At this time, the user inserts the pin 204 back into the insertion hole 203 to complete the fixation of the relative positions of the extension rod 202 and the connecting tube 201. Next, the user pulls the inner tube 205 upwards to adjust it to the height required for training. Then, the user rotates the connecting rod 404, which, with the help of the torsion spring 403, rotates the locking half-ring 405, causing the inner wall of the locking half-ring 405 to fit tightly against the surface of the inner tube 205. After both locking half-rings 405 on both sides are engaged with the inner tube 205, the user inserts the plug rod 407 into the connecting hole 406 to further secure the inner tube 205. At this point, the preparation of the obstacle course is complete, and the user can proceed with the training according to specific requirements. After training, the user first pulls out the plug rod 407 and the pin 204, then rotates the locking half ring 405 to release it from the locking state with the inner tube 205, allowing the inner tube 205 to slide downwards and return to its initial position. After the inner tube 205 is reset, the user applies a certain external force to the extension rod 207, pushing it inwards towards the crossbar 206 to reset the extension rod 207. At the same time as the extension rod 207 resets, the extension rod 202 will also reset synchronously. After the entire obstacle frame is completely reset, the user can store it properly for future use.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
