[0031] 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.

[0032] Reference Figure 1-4This utility model provides an embodiment of an athletic hurdle that is easy to install and disassemble, including a connecting rod 1. Fixed rods 2 are fixedly installed at both ends of the connecting rod 1. A fixed groove 3 is provided at the top of the fixed rod 2. A support leg 4 is provided on the right side of the fixed rod 2. A horizontal plate 5 is provided at the top of the connecting rod 1. The horizontal plate 5 is located at the bottom of the inner wall of the fixed groove 3. A limiting component 6 for limiting the horizontal plate 5 is provided on the outer side of the connecting rod 1. First, the required horizontal plate 5 can be placed inside the fixed groove 3. Then, the horizontal plate 5 can be limited by the limiting component 6. Next, the support leg 4 is installed, thereby fixing the horizontal plate 5 and the support leg 4 for use.

[0033] Reference Figure 1-4 The limiting component 6 includes two sets of mounting blocks 61, with the top of the mounting blocks 61 and the bottom of the horizontal plate 5 fixedly mounted. A placement groove 62 is provided inside the fixing rod 2, and an insertion rod 63 is provided inside the placement groove 62. The outer end of the insertion rod 63 extends through to the outside of the mounting block 61 and is inserted into the mounting block 61. Through the cooperation of the mounting blocks 61, the placement groove 62, and the insertion rod 63, when the horizontal plate 5 enters the bottom of the inner wall of the fixing groove 3, the insertion rod 63 can be pushed outwards. The insertion rod 63 moves outwards and passes through the mounting block 61, thereby limiting the mounting block 61 and the horizontal plate 5 and preventing the horizontal plate 5 from detaching from the fixing groove 3. A spring 64 is fixedly mounted on one side of the inner wall of the placement groove 62, and a rectangular block 65 is fixedly mounted on the outer end of the spring 64. The surface of the rectangular block 65 and the placement groove 62 are fixedly mounted on the spring 64. The inner side of the slot 62 is slidably installed, and the outer side of the rectangular block 65 and the inner end of the insertion rod 63 are fixedly installed. Through the cooperation of the spring 64 and the rectangular block 65, the rectangular block 65 and the insertion rod 63 can always bear the elastic force of the spring 64, which makes the insertion rod 63 more stable when passing through the fixed block. The outer side of the mounting block 61 is provided with a through slot 8, and the outer side of the insertion rod 63 is fixedly installed with a pull rod 9. The pull rod 9 and the through slot 8 are slidably installed. Through the cooperation of the through slot 8 and the pull rod 9, when it is necessary to disassemble the horizontal plate 5, the pull rod 9 can be pushed inward. The pull rod 9 will squeeze the insertion rod 63, and the insertion rod 63 will drive the rectangular block 65 to move inward. The movement of the rectangular block 65 inward will cause the insertion rod 63 to separate from the mounting block 61. Then the horizontal plate 5 can be pulled up to remove it.

[0034] Reference Figure 1-4The top and bottom of the inner wall of the placement groove 62 are fixedly installed with stop blocks 7. The stop blocks 7 are configured to limit the rectangular block 65, which is located between the spring 64 and the stop blocks 7. By setting the stop 7, the rectangular block 65 and the insertion rod 63 can be limited, preventing the insertion rod 63 from being unable to limit the mounting block 61 due to the excessive elastic force of the spring 64. The left side of the support leg 4 is fixedly installed with a limiting rod 10. The left end of the limiting rod 10 passes through the outer end of the fixed rod 2 and is slidably installed with the fixed rod 2. By setting the limiting rod 10, the support leg 4 can be pushed to the left. The movement of the support leg 4 causes the limiting rod 10 to pass through the fixed rod 2, thereby allowing the support leg 4 to be inserted and limited. The internal thread of the limiting rod 10 is fitted with a bolt 11. The right side of the bolt 11 contacts the left side of the fixed rod 2. By setting the bolt 11, when the left side of the support leg 4 contacts the right side of the fixed rod 2, the bolt 11 can be rotated. The bolt 11 will enter the interior of the fixed rod 2, and the right side of the bolt 11 will gradually contact the left side of the fixed rod 2, thereby allowing the support leg 4 to be installed.

[0035] Working principle: First, the horizontal plate 5 can be placed inside the fixing slot 3. Since the insertion rod 63 is always under the elastic force of the spring 64, the insertion rod 63 will move outward and pass through the mounting block 61. At this time, the horizontal plate 5 can be installed. Then, the support leg 4 can be pushed to the left. The support leg 4 moves and drives the limiting rod 10 to pass through the fixing rod 2. When the left side of the support leg 4 contacts the right side of the fixing rod 2, the bolt 11 can be rotated. The bolt 11 will enter the interior of the fixing rod 2, and the right side of the bolt 11 will gradually contact the left side of the fixing rod 2, thus allowing the support leg 4 to be installed. When it is necessary to disassemble the horizontal plate 5, the connecting rod 1 can be pushed inward. The connecting rod 1 moves inward and drives the insertion rod 63 and the rectangular block 65 to move inward. At this time, the insertion rod 63 will disengage from the mounting block 61, and then the horizontal plate 5 can be removed.

[0036] 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.
