A folding hurdle for sports

Abstract

The invention discloses a folding hurdle for sports, which comprises a hurdle body, a fixed pole, a vertical pole, a moving pole, an adjustment mechanism and a protective fence. The hurdle body (1) is connected to a fixed pole (2) through a vertical pole (21). , the top surface of the fixed rod is welded with the vertical rod, the left and right sides of the front end of the fixed rod are equipped with moving rods, the inside of the fixed rod is equipped with an adjustment mechanism, and the middle parts of the two guardrails are attracted by two second magnets , the foam board on the surface of the guardrail provides protection for the user. The surface of the foam board is a soft board and when the two guardrails are impacted by the outside, the two guardrails rotate outwards along the built-in second rotating shaft and disconnect, reaching a The instep of the trainer directly hits the vertical guardrail to prevent injury. During the training process, the user's joints hit the foam board without causing pain. A direct hit to the fence caused pain and injury to delay the game.

Description

technical field [0001] The invention relates to the field of folding hurdles, in particular to a folding hurdle for sports. Background technique [0002] The hurdle frame has been widely used in school physical education teaching, training and competitions. Generally, the ordinary hurdle boards and poles are riveted and fixed. When hurdling, the instep of the student is easy to directly hit the board, and the material of the board is relatively hard. Moreover, keeping the fence boards horizontally will cause the students' insteps to be easily hurt and injured. [0003] However, the existing folding hurdles have the following problems: [0004] 1. In the existing folding hurdles, the hurdles are fixed horizontally and vertically during the training process and the material of the hurdles is relatively hard, which causes the instep of the student to directly hit the hurdles, causing pain, injury and delaying the game. [0005] 2. In the existing folding hurdles, the ordinary...

Problems solved by technology

[0009] The invention provides a folding hurdle for sports through improvement. The middle parts of the two guardrails are attracted by two second magnets. The foam board on the surface of the guardrail provides protection for the user. When the fence board is impacted by the outside, the two fence boards rotate outward along the built-in second rotating shaft and disconnect, so that the instep of the trainer directly hits the vertical fence board to prevent injury, and the user's joints hit the foam board during the training process. The beneficial effect of pain solves the problem that the fence is fixed horizontally and vertically during the training process and the fence is made of hard material, causing the student's instep to directly hit the fence, causing pain, injury and delaying the game; rotating the bottom runner on the right end of the pole, turning The wheel drives the second bevel gear to rotate through the third rotating shaft, and then the second bevel gear drives the top to mesh with the first bevel gear to rotate, and then the inner groove of the first bevel gear drives the top screw to rotate at the bottom of the inner rod through the flat key. After the rotation, the top slider is driven to slide upward inside the pole, and at the same time, the slider drives the inner pole to rise. During the lifting process of the inner pole, the height of the front-end guardrail is adjusted through the triangular connection piece. After the rotation is placed at the specified height, under the force of the spring, The ratchet locks the surface of the second bevel gear to prevent its rotation. After the training is completed, pull the pull block, so that the top of the ratchet at the front end of the pull block rotates backwards and separates from the second bevel gear. Under the force of the inner rod, the screw rotates to drive the slider Slide down, so that the inner rod can be stored and folded inside the vertical rod, which achieves the beneficial effect of convenient and quick storage. The buckle parts are easy to lose and the use is cumbersome; hold the outside of the pole with your hand, and then push the pole to move the hurdle body through the bottom runner. To control the moving direction of the hurdle body, and move the hurdle body to the designated site and then loosen the connecting nut so that the bottom surface of the bottom rubber plate is lower than the bottom of the runner to support the top hurdle body, achieving the process of moving in the plane The beneficial effect of saving time and labor in the medium and long-distance hurdles solves the problem that the hurdle body is large in volume and weight, and cannot be dragged by the mobile device during the plane handling process, resulting in time-consuming and labor-intensive problems in the handling process.
