Description

Technical Field

[0001] The utility model relates to the field of sports training devices, in particular to an archery sports training device. Background Art

[0002] Archery is a common form of sport. In order to improve their archery skills, archers need to undergo high-intensity archery training. There are the following problems when using real bows and arrows for training: 1. Using real bows and arrows to train is dangerous and can only be done in specific places; 2. If the bow is not equipped with arrows and the bowstring is empty, the huge potential energy generated by the deformation of the bowstring cannot be transmitted through the arrow, which can easily cause damage to the bowstring. If the bowstring collapses, it may also cause injuries to the archer.

[0003] For example, the Chinese invention patent application with application number 202310684815.5 provides an arrowless bow; it imitates the tension of the bowstring when stretching the arrow through a hydraulic gas spring; through the damping action of the hydraulic gas spring itself, the second grip unit is slowly reset, avoiding the problem of damage to the arrowless bow due to excessive rebound force and rebound speed; archers can safely release the bowstring for archery training.

[0004] However, it has the following problems: 1. Its design still adopts the traditional bow and arrow shape, which is large in size and inconvenient to carry, and is not convenient for short-term practice in other places; 2. The maximum stretching length of the bowstring is limited by the size of the bow body. When the bow body is small, it cannot simulate the use scenario of a large bow. When the bow body is large, it will make the arrowless bow more inconvenient to carry. Utility Model Content

[0005] Aiming at the problems that the archery training device in the prior art is inconvenient to carry during use and it is difficult to take into account the training of using a large bow, the utility model proposes an archery training device.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An archery training device comprises an integral shell, a hydraulic rod fixing bracket is arranged inside the integral shell, a hydraulic mechanism is installed on the hydraulic rod fixing bracket, the hydraulic mechanism comprises a stretching hydraulic rod and a contraction buffer hydraulic rod, a pulley group cable connected to the hydraulic mechanism is arranged inside the integral shell, one end of the pulley group cable extends out of the integral shell; a pulley group for the pulley group cable to pass through is also arranged inside the integral shell, and the pulley group is used to increase the torque of the pulley group cable stretching.

[0008] The utility model can simulate the tension of the bowstring when it is stretched by stretching the hydraulic rod; installing a contraction buffer hydraulic rod in the shell can prevent the pulley cable and the hydraulic mechanism from shrinking too quickly when the cable is loosened, so that the hydraulic rod and the cable can be slowly and evenly retracted into the overall shell. When in use, the trainer holds the overall shell with one hand and the pulley cable with the other hand to stretch it outward. The pulley block is set to increase the torque of the pulley cable, so that the distance the pulley cable is pulled out of the overall shell is several times the distance the hydraulic rod extends, thereby effectively reducing the volume of the overall shell, making the archery trainer in the utility model more compact and convenient to carry; at the same time, the setting extends the movable distance of the pulley cable, so that the archery trainer in the utility model can simulate the use scenario of a large bow, and when the archery trainer in the utility model is used, one hand holds the shell and the other hand holds the cable to stretch it outward.

[0009] Preferably, a front pulley fixing seat is fixedly connected to the hydraulic mechanism, and the front pulley fixing seat can move in the overall shell along with the movement of the hydraulic mechanism; a rear pulley fixing seat is also fixed in the inner cavity of the overall shell, and a plurality of pulley groups are arranged inside the front pulley fixing seat and the rear pulley fixing seat; one end of the pulley group cable is fixed to the front pulley fixing seat, and the other end passes through the pulleys and the rear pulley fixing seat in sequence and then extends out of the overall shell.

[0010] The front pulley fixing seat of the utility model better realizes the installation of the movable pulley in the pulley block, and the rear pulley fixing seat better realizes the installation of the fixed pulley in the pulley block. By increasing the number of pulleys, the moving distance of the pulley block cable can be increased multiple times.

[0011] Preferably, one end of the pulley cable extending out of the overall housing is provided with a cable end rope ring.

[0012] The rope ring in the utility model can facilitate the training personnel to hold the pulley cable, and can also simulate archery in a relatively realistic manner.

[0013] Preferably, the front pulley fixing seat and the rear pulley fixing seat are provided with a pulley fixing shaft pin for installing the pulley.

[0014] The utility model realizes the installation of the pulley relatively easily through the pulley fixing shaft pin. The maximum stretching distance of the pulley group cable required in different usage scenarios is different. The setting of the pulley fixing shaft pin can make it more convenient and quick for users to replace the number of pulleys, and then adjust the maximum stretching distance of the pulley group cable.

[0015] Preferably, the overall shell is configured as a cylinder with openings at both ends, the hydraulic mechanism, the front pulley fixing seat and the rear pulley fixing seat are axially arranged in the cylinder, and the front decorative plugging cover and the rear decorative plugging cover are arranged at the openings at both ends of the cylinder.

[0016] The utility model sets the overall shell to be cylindrical, which can save the volume of the overall shell and make the hydraulic mechanism, the front pulley fixing seat and the rear pulley fixing seat more compactly installed in the shell of the overall shell; at the same time, the front decorative plugging cover and the rear decorative plugging cover are arranged at the openings at both ends of the cylinder, which can effectively prevent dust from falling into the shell of the overall shell, thereby extending the service life of the archery trainer; and the cylindrical shell structure can be convenient for users to hold.

[0017] Preferably, a gripping handle is sleeved on the outside of the overall shell, and the gripping handle can move forward and backward along the overall shell. The overall shell is also provided with a fixing device for fixing the gripping handle on the overall shell.

[0018] The setting of the handle in the utility model allows the user to better hold the entire shell and then conduct simulation training. At the same time, the holding handle is set to be movable forward and backward along the shell, so that the trainer can adjust the position of the holding handle on the entire shell in time according to the actual use scenario, so that the trainer has a better human-computer interaction experience.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0024] like Figure 1 As shown, this embodiment provides an archery training device, including an integral housing 14. In order to make the volume of the integral housing 14 smaller, the integral housing 14 can be designed to be cylindrical. A hydraulic mechanism is arranged in the integral housing 14, and the hydraulic mechanism includes a hydraulic rod fixing bracket. The hydraulic rod fixing bracket 2 is fixed to the inner cavity of the integral housing 14 through a hydraulic rod fixing nut 3.

[0025] The tension of the bowstring when stretched is simulated by the stretching hydraulic rod 5 on the hydraulic rod fixing bracket, and the contraction buffer hydraulic rod 4 on the hydraulic rod fixing bracket 3 is used to prevent the pulley group cable 7 and the hydraulic mechanism from contracting too quickly when the cable is loosened, so that the stretching hydraulic rod 5, the contraction buffer hydraulic rod 4 and the pulley group cable 7 can be slowly and evenly retracted into the overall housing 14. When in use, the overall housing 14 is held with one hand and the pulley group cable 7 is stretched with the other hand.

[0026] The overall housing 14 is provided with a pulley cable 7 connected to the hydraulic mechanism, and one end of the pulley cable 7 extends out of the overall housing 14; the overall housing 14 is also provided with a pulley block for the pulley cable 7 to pass through, and the pulley block is used to increase the torque of the pulley cable 7. The distance that the pulley cable 7 is pulled out of the housing is several times the moving distance of the hydraulic mechanism, thereby effectively reducing the volume of the overall housing 14, making the archery trainer in this embodiment more compact and convenient to carry; at the same time, this setting extends the movable distance of the pulley cable 7, so that the archery trainer in this embodiment can simulate the use scenario of a large bow.

[0027] By adding the number of pulleys in the pulley block, the moving distance of the pulley block cable 7 can be multiplied. Therefore, the front pulley fixing seat 6 is fixed to the hydraulic mechanism, and the front pulley fixing seat 6 can move in the overall shell 14 with the movement of the hydraulic mechanism; the rear pulley fixing seat 8 is also fixed in the inner cavity of the overall shell 14, and one end of the pulley block cable 7 is fixed to the front pulley fixing seat 6, and the other end passes through each pulley and the rear pulley fixing seat 8 in sequence and then extends out of the overall shell 14. Figure 2 As shown, the pulley 15 is installed in the front pulley fixing seat 6 and the rear pulley fixing seat 8 through the pulley fixing shaft pin 10, so that the staff can more conveniently adjust the number of pulleys 15, and then adjust the maximum moving distance of the pulley block cable 7. One end of the pulley block cable 7 is fixed to the front pulley fixing seat 6, and the other end passes through each pulley 15 and the rear pulley fixing seat 8 in sequence and then extends out of the overall housing 14.

[0028] Although the trainer can train by pinching the pulley cable 7 with his fingers, the training process will cause fatigue to the trainer's fingers, and the process of archery is not restored enough, which greatly affects the training effect. In order to facilitate the trainer to stretch the cable and improve the training effect, auxiliary tools such as a releaser, a finger guard, and a thumb wrench can be connected to the end of the pulley cable 7 extending out of the overall housing 14. For example, in this embodiment, a cable end rope ring 11 is set at the end 7 of the pulley cable, and the trainer can insert his finger into the cable end rope ring 11 to stretch the pulley cable 7, which strongly restores the scene of archery training and improves the training effect.

[0029] During the use of the archery trainer in this embodiment, parts inside the overall shell 14 may need to be replaced and repaired. Therefore, the openings at both ends of the cylinder can make it easier for maintenance personnel to repair the corresponding damaged parts. In order to prevent dust from falling into the shell of the overall shell 14 through the port of the cylinder, a front decorative plug cover 1 and a rear decorative plug cover 9 are installed at the port.

[0030] In order to make the archery simulator in this embodiment better simulate archery, a gripping handle 12 is provided outside the overall housing 14, so that the trainee can hold the overall housing 14 by gripping the gripping handle 12. The gripping handle 12 is set to be position-adjustable, and the user can adjust the gripping handle 12 to the optimal position according to the specific usage scenario, and then fix it with a fixing device, so that the trainee can have a better human-computer interaction experience. The fixing device can be fixed with a handle fixing screw 13, and this fixing method has the advantage of being more convenient to disassemble.

[0031] In conclusion, the above are only preferred embodiments of this embodiment, and all equivalent changes and modifications made according to the scope of the patent application of this embodiment should fall within the scope of the patent of this embodiment.
