Description

An easy-lifting hurdle frame for training

technical field

The utility model belongs to the technical field of sports equipment, in particular to an easy-to-lift hurdle frame for training.

Background technique

Hurdles are a very healthy and interesting sports item. Along with the popularization of hurdles in primary and secondary schools, hurdlers have become more and more important sports equipment. Because the hurdle frame is often kicked down during hurdle competition or training, it is inconvenient to use. At present, the commonly used hurdle frame has a hurdle board and a column as an integral structure. Every time the hurdle board is knocked off or the hurdle is knocked down, someone needs to be specially assigned to put the hurdle board back on the support bar or lift up the hurdle. This has just greatly improved the manpower and energy that serve for the hurdler, wasted a lot of practice time, slowed down the efficiency of practice, and can't lift the height, making it inconvenient for practitioners or beginners to train and use. There are concerns about the safety of the hurdles, and many people are afraid of being tripped by the hard railings. Therefore, many people dare not try, and lose the opportunity to exercise with the help of hurdles and experience the fun of hurdles.

CN202336219U discloses a non-falling hurdle frame, including a hurdle frame, and the bottom of the hurdle frame is fixed on the runway by screws. The non-falling hurdle frame of the utility model is made of rubber and other materials with good elasticity, and the bottom is fixed on the track, so it can bounce up automatically after the hurdle frame is kicked over by athletes, avoiding the trouble of manual lifting and returning Although this utility model can automatically reset after knocking off the hurdle board, avoiding the trouble of manual lifting, the hurdle frame needs to be fixed on the runway with screws, which is inconvenient for installation and disassembly, and takes time and effort.

CN202638002U discloses a hurdle frame, which includes a base and a hurdle arranged above the base, and also includes interconnected legs and support arms, and the top of the support arm supports the hurdle. The support leg is provided with a pin hole, and the support arm is provided with a plurality of pin holes matching with the pin hole, and the support leg and the support arm are fixed by the pin and the pin hole and the pin hole. A spring is provided between the base and the legs. Although the installation of the above-mentioned patents is very convenient, it avoids kicking the hurdle down when hurdling, and is easy to install. The one-piece structure makes it easy for athletes to trip and fall when they hit the top hurdle board. Although the height can be adjusted and there is no need to manually lift it up, it is still not the safest and most reliable solution, and it is too simple to use only spring connections. The purpose of making the hurdle frame reset cannot be realized, and after the spring is repeatedly bent beyond its yield strength, the hurdle frame will not be perpendicular to the runway, will not be usable, and the inconvenience of maintenance will affect the service life.

Contents of the invention

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a training easy-lifting hurdle frame with simple structure, long service life, convenient use, and adjustable height of the hurdle board.

Aiming at the deficiencies in the existing technology, the technical problem to be solved by the utility model is to provide a hurdle board that can maintain its own balance, so that the hurdle board can return to its original position by itself after an external force collision, and solve the problem that the hurdle board is impacted by an external force when it is in use.

The utility model has the advantages of the easy-lifting hurdle frame for training: the utility model adopts the telescopic structure of the fixed column and the movable column, and sets the locking structure of the limit hole and the elastic protrusion, so that the height of the hurdle frame can be adjusted conveniently, so that The hurdle is suitable for people with different height requirements, which improves the utilization rate of the hurdle and makes full use of resources. It not only overcomes the shortcomings of the common hurdle frame that is inconvenient to lift, but also adopts plug-in or magnetic connection between the hurdle board bracket and the hurdle column. The method can realize the function of separation at any time, so that athletes will not be tripped by the hurdle board even if they touch the hurdle board during the competition or training process, which greatly improves the safety performance. While meeting the needs of competition and training, this structure also The installation is more convenient. The combination of the seat body and the swing rod is adopted. Through the interaction of the reset support springs on both sides of the swing rod, the trouble of manually lifting the hurdle board due to being kicked down is avoided. The structure is more compact, the service life is longer, and the height of the hurdle column in the utility model is lower than the height of the hurdle board, which reduces the influence of the traditional hurdler on the athlete when the hurdle column is higher than the hurdle board, so that the athlete It can be played normally during competition or training; the utility model has the advantages of simple structure and low cost, and is suitable for popularization and application.
