Description

Technical Field

[0001] The invention relates to the field of archery auxiliary practice equipment, in particular to an archery auxiliary practice equipment. Background Art

[0002] Archery, or the art of archery, refers to a sport that uses the elastic force of a bow to shoot arrows and compete for accuracy within a certain distance. It is also known as archery. As early as 10,000 years ago in the Middle Stone Age, humans invented bows and arrows for hunting and fishing. Later, bows and arrows were one of the weapons used in wars. Now archery exists as a sport that people like. The origin of archery can be traced back to about 50,000 BC. It was once popular in ancient Africa, Europe, Asia and other regions. China invented bows and arrows as early as the late Paleolithic Age. Bows and arrows have always been an important weapon for people to hunt and the army to fight. Modern archery originated in Britain in the 14th century. It evolved from the military needs of warriors to an entertainment activity. In the 16th century, three forms of archery appeared: the first is target archery, the second is ground target archery, and the third is roaming archery. The three important world archery championships are: the World Outdoor Archery Championships, the World Indoor Archery Championships and the World Field Archery Championships;

[0003] Existing archery training devices generally adopt a fixed length method or a collision blocking method, but have the following shortcomings:

[0004] 1. Fixed-length method: Since the length of the ruler is fixed, it is impossible to feel the series of body movements, strength maintenance, and muscle force during the bow drawing and shooting process, and it is impossible to produce a good training effect.

[0005] 2. The impact-blocking method simply uses parts to hit the cover and other obstructions at the end of the stroke, which produces great vibration during use and cannot be safely used with compound bows and other bows that generate large amounts of energy.

[0006] Third, the existing training device cannot be installed and used without changing the position of the accessories on the existing bow body, the training is not consistent with the actual situation, and the training effect is poor. Therefore, we propose an archery auxiliary training device. Summary of the invention

[0007] The object of the present invention is to provide an auxiliary training device for archery to solve the problems that the fixed length method proposed in the above background technology cannot produce a good training effect because the length scale rod is fixed, and the series of body movements, strength maintenance, and muscle force experience during the bow drawing and shooting process cannot be felt, and the impact blocking method simply uses parts to hit the cover and other blocking objects at the end of the stroke, which produces great vibration during use, and cannot be safely used with compound bows and other bows that generate large energy, and the existing training device cannot be installed and used without changing the position of the accessories on the existing bow body, the training is inconsistent with the actual situation, and the training effect is poor.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an archery auxiliary practice device, comprising a base, the left side of the base is rotatably connected to a rear cantilever, the top of the base is fixedly connected to a main pipe seat, the right side of the base is rotatably connected to the front cantilever, the left end of the main pipe seat is connected to a main pipe, and the right end of the main pipe inner cavity is provided with a piston push rod, the surface of the piston push rod is provided with a coupling, the end of the piston push rod away from the main pipe is fixedly connected with a tail buckle, the surface of the tail buckle is provided with a tail buckle pressure plate, both sides of the bottom of the base are provided with a base pressure plate gasket, the side of the base pressure plate gasket away from the base is provided with a base pressure plate, a base gasket is provided between the base and the base pressure plate gasket, the left end of the main pipe inner cavity is rotatably connected with a piston through a rotating shaft, the piston is clamped with the piston push rod, both sides of the bottom of the base pressure plate are penetrated with base pressure plate locking nuts, and the base pressure plate locking nuts are threadedly connected with the base.

[0009] Preferably, the left end of the inner cavity of the main pipe is connected to a front closing cover via threads, and the right side of the inner cavity of the front closing cover is clamped with a composite valve body.

[0010] Preferably, an air pressure regulating bolt penetrates the left end of the front closing cover, and the air pressure regulating bolt is threadedly connected to the front closing cover.

[0011] Preferably, a first auxiliary support fixing seat is sleeved on the top of the surface of the main pipe, and a second auxiliary support fixing seat is sleeved on the bottom of the surface of the main pipe. The first auxiliary support fixing seat and the second auxiliary support fixing seat are fixedly connected by bolts, and the bottom of the second auxiliary support fixing seat is rotatably connected to an auxiliary support head via a rotating shaft.

[0012] Preferably, one end of the auxiliary support head away from the second auxiliary support fixing seat is fixedly connected to an auxiliary support rod, and one end of the auxiliary support rod away from the auxiliary support head is fixedly connected to an auxiliary support claw.

[0013] Preferably, the inner cavity of the front closing cover is provided with an air pressure regulating spring and a composite valve body, the inner cavity of the composite valve body is provided with a steel ball, the bottom of the composite valve body is provided with a steel ball stop bolt, and the composite valve body is threadedly connected to the steel ball.

[0014] Preferably, the air pressure regulating spring is arranged between the composite valve body and the air pressure regulating bolt, and the number of the air pressure regulating spring is one.

[0015] Preferably, the main pipe seat is connected to the rear cantilever and the front cantilever, and the rear cantilever and the front cantilever are connected to the base.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the piston push rod is used to move in the inner cavity of the main tube, the air in the inner cavity of the main tube can be continuously compressed to absorb the energy generated by the bowstring during the firing process, which can effectively avoid the collision with obstacles. The method of simply using parts to hit the cover at the end of the stroke and other obstacles will produce great vibrations during use, and compound bows and other bows that generate large energy cannot be used safely. The designed base, rear cantilever, front cantilever, main tube seat, first auxiliary support fixing seat, second auxiliary support fixing seat, auxiliary support rod and auxiliary support claw have a large adjustment range, which can be directly and quickly installed and used without changing the position of existing key accessories on the bow body, so that archers can safely use their own archery equipment to practice the whole process of archery in places without archery conditions, which is more helpful for archery entry training, action correction, equipment trial and pre-match practice;

[0018] Second, by using an independent adjustable base, a main pipe seat, a first auxiliary support fixing seat, a second auxiliary support fixing seat, an auxiliary support rod and an auxiliary support claw, it can be well compatible with most of the current bows and can be installed and used normally without changing the installation position of the bow accessories. It can effectively avoid the situation that the existing trainer cannot be installed and used without changing the position of the accessories on the existing bow, the training is not consistent with the actual situation, and the training effect is poor. In addition, for compound bows and other bows with large energy, the energy generated during the launch process is absorbed by continuously compressing the air, and the pre-pressure of the compression spring between the air pressure adjustment bolt and the compound valve body can be changed. The method can adapt to the normal use of bows with different energy sizes, thereby effectively solving the problem that the fixed length method, because the length scale rod is fixed, cannot feel the series of body movements, strength maintenance, and muscle force experience during the bow drawing and shooting, and cannot produce a good training effect. The impact and blocking method, because the only method of using parts to hit the cover and other obstructions at the end of the stroke, produces great vibration during use, and cannot be safely used with compound bows and other bows that generate larger energy, and the existing trainer cannot be installed and used without changing the position of the accessories on the existing bow body, the training is not consistent with the actual situation, and the training effect is poor.

It can effectively avoid the situation that the existing training device cannot be installed and used without changing the position of the accessories on the existing bow, the training is not consistent with the actual situation, and the training effect is poor. In addition, it is designed for compound bows and other bows with higher energy. The energy generated during the launch process is absorbed by continuously compressing the air, and the pre-pressure of the compression spring between the air pressure regulating bolt and the composite valve body can be changed to adapt to the normal use of bows with different energy sizes. The auxiliary support rod 23 is fixedly connected to the auxiliary support claw 24 at one end away from the auxiliary support head 20. , air pressure regulating springs 27 are arranged on both sides of the steel ball 25, and the air pressure regulating springs 27 are arranged between the composite valve body 18 and the air pressure regulating bolt 19. There are two air pressure regulating springs 27, and a coupling 7 is arranged on the surface of the piston push rod 6. The end of the piston push rod 6 away from the main pipe 5 is fixedly connected with a tail buckle 8, and the surface of the tail buckle 8 is provided with a tail buckle pressure plate 9. Both sides of the bottom of the base 1 are provided with a base pressure plate gasket 11, and the side of the base pressure plate gasket 11 away from the base 1 is provided with a base pressure plate 12, and a base gasket 13 is arranged between the base 1 and the base pressure plate gasket 11. The left end of the inner cavity of the main pipe 5 is rotatably connected with a piston 14 through a rotating shaft, and the piston 14 is clamped with the piston push rod 6. Both sides of the bottom of the base pressure plate 12 are penetrated with a base pressure plate locking nut 16,The base pressure plate locking nut 16 is threadedly connected to the base 1. When the piston push rod 6 moves in the inner cavity of the main pipe 5, the air in the inner cavity of the main pipe 5 can be continuously compressed to absorb the energy generated by the bowstring during the shooting process, which can effectively avoid the collision and obstruction method. Because the method of simply using parts to hit the cover and other obstructions at the end of the stroke generates great vibration during use, and compound bows and other bows that generate large energy cannot be used safely. The designed base 1, rear cantilever 2, main pipe seat 3, first auxiliary support fixing seat 21, second auxiliary support fixing seat 22, auxiliary support rod 23 and auxiliary support claw 24 have a large adjustment range, which can be directly and quickly installed and used without changing the existing key accessory positions on the bow body, so that the archer can Even in places without archery conditions, people can safely use their own archery equipment to practice the whole process of archery, which is very helpful for archery entry training, action correction, equipment trial, and pre-match practice. This can effectively solve the problem that the fixed length method cannot produce a good training effect because the length scale rod is fixed and the series of body movements, strength maintenance, and muscle force experience during the bow opening and shooting process cannot be felt. In addition, the impact blocking method generates great vibration during use because the parts are simply used to hit the cover and other blocking objects at the end of the stroke. It cannot be used safely with compound bows and other bows that generate large energy, and the existing trainer cannot be installed and used without changing the position of the accessories on the existing bow body, resulting in the inconsistency between training and practice and poor training effect.

[0025] Working principle: During use, the tail buckle 8 locks the bowstring and connects it with the piston push rod 6. In the process of pulling the bow, the bowstring drives the piston push rod 6 and the piston 14 to move to the right in the main pipe. At this time, the space in front of the piston 14 generates negative atmospheric pressure, and the external air enters the space in front of the piston 14 from the air inlet channel of the composite valve body 18 in the left front closing cover 17 until it is equal to the external atmospheric pressure. In the process of launching, the bowstring pushes the piston push rod 6 and the piston 14 to move quickly to the left side of the figure in the main pipe. The air pressure in front of the piston 14 increases. The air pressure first pushes the steel ball located in the air inlet channel of the composite valve body 18 to move to the left, so that the steel ball closes the air inlet channel to ensure that the air pressure rises smoothly. The continuously rising air pressure begins to generate a reverse thrust on the piston 14, absorbing the launching energy of the bowstring. When the air pressure exceeds the preset pressure, the air pressure pushes the composite valve body 18 to overcome the pressure of the air pressure regulating spring 27 and leave the sealing surface. Excess air pressure leaves through the exhaust channel of the composite valve body 18. When the air pressure is lower than the preset pressure, the valve core body of the composite valve body 18 is reset under the action of the air pressure regulating spring 27, and the exhaust channel is closed. At this time, because part of the air pressure has been discharged, the piston push rod 6 will not rebound too much, which can effectively solve the problem that the fixed length method cannot feel the series of body movements, strength maintenance, and muscle force experience during the bow opening and shooting process because the length scale rod is fixed, and cannot produce a good training effect. The impact and blocking method simply uses parts to hit the cover and other obstructions at the end of the stroke, which produces great vibration during use. It is also unsafe to use compound bows and other bows that generate more energy, and the existing trainers cannot be installed and used without changing the position of accessories on the existing bow body, resulting in the problem that training is not consistent with reality and the training effect is poor.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
