[0002] Track and field sports is the full name of field events, track events and all-around competitions. Modern track and field sports are classified differently, mainly including race walking, running, jumping, throwing and all-around sports consisting of some events of running, jumping, leaping and throwing, totaling more than 40 events. For track and field athletes, well-developed leg muscles and lasting endurance are necessary conditions for achieving good results. Therefore, leg training is also an indispensable item in daily training. However, when training with weights to increase explosive power, it is easy to suffer compression injuries to the leg joints during the process of leg opening and closing and when the legs are bent. Moreover, it is boring and tedious during long-term training, and the athletes' training enthusiasm is reduced due to the increase in physical fitness during training, because the singleness of the original training equipment cannot meet the requirements of comprehensive training for existing athletes.

[0003] In track and field hurdle training, trainers usually perform close-range leg-lifting hurdle training in order to improve stability when hurdling.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a comprehensive physical training device for track and field events includes two groups of bases 1, and the two groups of bases 1 are provided with fixed columns 2. The fixed columns 2 and the bases 1 can be fixedly connected or connected by plug-in connection, which can be selected according to actual needs or usage methods. Then, threaded grooves 201 are opened on the inner walls of the two groups of fixed columns 2, and threaded rods 301 are threadedly connected inside the two groups of threaded grooves 201. Lifting rods 3 are fixedly connected to the tops of the threaded rods 301, and blocking rods 4 are connected between the tops of the two groups of lifting rods 3. The threaded rods 301 are rotated in the threaded grooves 201 inside the fixed columns 2, thereby driving the blocking rod 4 at the top of the lifting rod 3 to adjust the height, and the blocking rod 4 can be adjusted to different subtle heights to improve the accuracy of training intensity.

[0022] like Figure 3 As shown, the outer wall of the threaded rod 301 is provided with a groove 302, and the inner wall of the groove 302 is provided with scale lines 5. The setting of the scale lines 5 inside the groove 302 allows the height of the top stop rod 4 of the lifting rod 3 to be judged by observing the displayed value of the scale lines 5 when the threaded rod 301 is rotated and lifted inside the thread groove 201, thereby improving the convenience of adjustment, and the setting of the groove 302 will not affect the thread rotation of the threaded rod 301.

[0023] like Figure 1 and Figure 2 As shown, there are two groups of baffle bars 4, and the two groups of baffle bars 4 are respectively connected to the tops of the two groups of lifting rods 3. By setting the two groups of baffle bars 4 separately, it can prevent the user from stepping on the baffle bars 4 during hurdle training, and the baffle bars 4 will not break. At the same time, the baffle bars 4 are made of elastic material, and when the user steps on the baffle bars 4, the baffle bars 4 can bend according to their own elastic properties, which can protect the user on the one hand and avoid damage to the baffle bars 4 on the other hand.

[0024] like Figure 2 and Figure 3As shown, a cavity 303 is formed on the inner wall of the lifting rod 3, and a buffer rod 601 is slidably connected to the inside of the cavity 303. A spring 6 is arranged inside the cavity 303, and the two ends of the spring 6 are respectively against the buffer rod 601 and the inner wall at the bottom of the cavity 303. The top of the buffer rod 601 passes through the top of the lifting rod 3 and is connected to the blocking rod 4. When the user is performing stride training or side leg lifting training, when the user's foot accidentally presses on the blocking rod 4, the blocking rod 4 is subjected to the applied pressure to drive the buffer rod 601 to move downward, thereby squeezing the spring 6. The spring 6 is squeezed and contracts to absorb and buffer the force received, thereby avoiding the pain caused by the user's foot colliding with the blocking rod 4, thereby improving the safety of training.

[0025] like Figure 2 and Figure 3 As shown, the top of the buffer rod 601 is fixedly connected to a socket 7, and a slot 701 is provided on the socket 7. Both ends of the blocking rod 4 are fixedly connected to connecting columns 401, and the connecting columns 401 are inserted into the slot 701. Through the setting of the slot 701 on the socket 7, the connecting column 401 at the end of the blocking rod 4 can be inserted into the slot 701 for installation, thereby improving the convenience of installation and disassembly. At the same time, the blocking rod 4 can be rotated to drive the connecting column 401 to rotate in the slot 701 to adjust the direction of the blocking rod 4.

[0026] like Figure 1 and Figure 2 As shown, a water storage chamber 101 is opened inside the base 1, and a sealing plug 102 is arranged on the top of the water storage chamber 101. Liquid is added into the water storage chamber 101 to increase the weight of the base 1, so that the base 1 can support the baffle 4 on the fixed column 2 and improve the stability of the support of the base 1. The sealing plug 102 arranged in the water storage chamber 101 seals the water storage chamber 101 to prevent the liquid in the water storage chamber 101 from leaking due to the shaking of the base 1.

[0027] The working principle of the utility model is as follows: when the user uses it, the sealing plug 102 on the water storage chamber 101 is removed to add liquid into the water storage chamber 101, and then the sealing plug 102 is used to seal the water storage chamber 101, so that the weight of the base 1 is increased by the addition of liquid, and the stability of the support of the base 1 is improved. Then, according to the height requirement of the user's physical training, the lifting rod 3 is rotated, and the lifting rod 3 drives the threaded rod 301 to rotate and move up and down in the thread groove 201 inside the fixed column 2, so as to adjust the height of the lifting rod 3, which is convenient for the user to perform fine height adjustment training, avoids the adjustment span being too large to affect the training effect, and improves the convenience of training. Then, the two sets of blocking rods are connected. 4 are respectively inserted into the card slot 701 on the card seat 7 through the connecting column 401 for fixing, and then the blocking rod 4 is rotated to be located between the two groups of fixing columns 2, so that the adjacent ends of the two groups of blocking rods 4 are opposite to each other, thereby completing the installation of the training device. When the user performs stride training, when the user accidentally kicks the blocking rod 4, the blocking rod 4 is bent and buffered by its own elasticity, thereby reducing the pain caused by the touch and improving the safety of the training. When the user steps on the blocking rod 4, the buffer rod 601 squeezes the spring 6 to drive the blocking rod 4 to move downward, and the blocking rod 4 is bent downward for buffering. While the user is buffered and protected, the device is also buffered and protected differently, thereby improving the safety of the user and the device.

[0028] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
