DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with specific implementation methods. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Embodiment 1

[0029] like Figure 1-10 As shown, the traditional bow training strength stability measuring instrument of the present invention comprises a holding rod body 1 and a tailless arrow 2, wherein a perforated fixing seat 3 is arranged in the middle of the holding rod body 1, a pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3, two slide bars 4 are arranged in parallel at the upper and lower ends of the front side of the perforated fixing seat 3, a reciprocating slider 5 is slidably sleeved on the two slide bars 4, a compression spring 6 is arranged between the reciprocating slider 5 and the perforated fixing seat 3, one end of the compression spring 6 is fixedly pressed against the middle of the reciprocating slider 5, and the pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3, and the pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3. The other end of the compression spring 6 presses against the pressure receiving part of the pressure sensor 7. Pulleys 8 are symmetrically arranged at both ends of the holding rod body 1. Tension ropes 9 are fixedly connected at the upper and lower ends of the reciprocating slider 5. One end of the tension rope 9 is fixed to the upper end of the reciprocating slider 5. The other end of the tension rope 9 passes through the pulleys 8 at both ends of the holding rod body 1 in sequence and is fixedly connected to the lower end of the reciprocating slider 5. The pressure sensor 7 is a hollow annular structure. The middle of the reciprocating slider 5 is provided with a shuttle hole 10 for the tailless arrow 2 to pass through. The front ends of the two slide bars 4 are provided with threaded studs 11 with positioning shoulders. A fixing member 12 is sleeved on the two threaded studs 11, and the fixing member 12 is fastened by a nut matched with the threaded studs 11. A clearance slot 13 is opened in the middle of the fixing member 12. Further, traction guide pulleys 14 are respectively arranged on the holding rod body 1 at the upper and lower ends of the front side of the perforated fixing seat 3. The setting of the traction guide pulley 14 can change the traction direction of the tension rope 9, so that the efficiency of bow pulling work becomes higher.

[0030] Furthermore, a positioning ring groove 15 for installing the compression spring 6 is provided in the middle of one side of the reciprocating slider 5, and the end of the compression spring 6 is inserted or welded in the positioning ring groove 15; a positioning convex sleeve 16 is provided on the periphery of the pressure receiving part of the pressure sensor 7, and the other end of the compression spring 6 is movably mounted in the positioning convex sleeve 16, and the end of the compression spring 6 presses on the pressure receiving part of the pressure sensor 7. The compression spring 6 is a power storage element that provides power for archery. Although the compression spring 6 has a certain pre-pressure when installed, it is not enough to ensure that it is in a relatively stable assembly state when rebounding after power storage. It is particularly important to insert or weld the end of the compression spring 6 in the positioning ring groove 15. It should be noted here that the parts are selected and replaced according to the assembly state between the compression spring 6 and the positioning ring groove 15. When the end of the compression spring 6 is fixed in the positioning ring groove 15 by welding, the reciprocating slider 5 and the compression spring 6 need to be replaced together when adjusting and adapting.

[0031] Furthermore, the holding rod body 1 is a hollow rigid structure, and the wire perforations of the pressure sensor 7 are provided on one side surface of the lower end of the holding rod body 1 and on the side wall of the perforated fixing seat 3. The wires of the pressure sensor 7 are sequentially passed through the wire perforations and connected to the PC end, and the pressure sensor 7 is mounted in the perforated fixing seat 3 and fixed by glue. The holding rod body 1 is made of stainless steel, and the hollow design not only saves materials but also prevents overweight. The hollow structure can also facilitate wire embedding, further protecting the wires of the pressure sensor 7 from damage.

[0032] Furthermore, a linear sleeve is provided on the reciprocating slider 5, and the reciprocating slider 5 is slidably connected to the two slide bars 4 through the linear sleeve. The design of the linear sleeve mainly reduces friction resistance and prevents direct wear between the reciprocating slider 5 and the slide bar 4, so as to ensure that the reciprocating slider 5 can adapt to long-term installation, adjustment and replacement.

[0033] Further, the nut 17 is a hemispherical nut. Its design is mainly to better protect the wear and damage of the ends of the two slide bars 4.

[0034] Furthermore, the two slide bars 4 are perpendicular to the front side of the perforated fixing seat 3, and the shuttle hole 10 is coaxially arranged with the perforated hole opened in the middle of the perforated fixing seat 3. This design is mainly to enable the tailless wing arrow 2 to be shot smoothly and without resistance when the arrow is put on the arrow for actual shooting. It should be pointed out here that the diameter of the tailless wing arrow 2 is 1 / 2 to 2 / 3 of the shuttle hole 10 and the perforated hole.

[0035] This embodiment mainly limits the pop-up position of the reciprocating slider 5 by adding a fixing member 12. During installation and adjustment, the end of the compression spring 6 is inserted into the positioning ring groove 15, which makes it more convenient to replace the compression spring 6. For the end of the compression spring 6 welded in the positioning ring groove 15, it is necessary to loosen the two ends of the tension rope 9 from the reciprocating slider 5, and the replacement process is relatively cumbersome. The connection method between the two ends of the tension rope 9 and the reciprocating slider 5 can be to pierce the tension rope 9, wrap it around, and fix the rope head and the tension rope 9 through a locking buckle to put it into the connecting holes at the upper and lower ends of the reciprocating slider 5, or to clamp the two ends of the tension rope 9 in the connecting holes at the upper and lower ends of the reciprocating slider 5 by screws or plugging wires.

[0036] Embodiment 2

[0037] like Figure 8 , Fig. 9 , Fig.11As shown, the traditional bow training strength stability measuring instrument of the present invention comprises a holding rod body 1 and a tailless arrow 2, wherein a perforated fixing seat 3 is arranged in the middle of the holding rod body 1, a pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3, two slide bars 4 are arranged in parallel at the upper and lower ends of the front side of the perforated fixing seat 3, a reciprocating slider 5 is slidably sleeved on the two slide bars 4, a compression spring 6 is arranged between the reciprocating slider 5 and the perforated fixing seat 3, one end of the compression spring 6 is fixedly pressed against the middle of the reciprocating slider 5, and the pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3, and the pressure sensor 7 is installed in the middle of the front side of the perforated fixing seat 3. The other end of the compression spring 6 presses against the pressure receiving part of the pressure sensor 7. Pulleys 8 are symmetrically arranged at both ends of the holding rod body 1. Tension ropes 9 are fixedly connected at the upper and lower ends of the reciprocating slider 5. One end of the tension rope 9 is fixed to the upper end of the reciprocating slider 5. The other end of the tension rope 9 passes through the pulleys 8 at both ends of the holding rod body 1 in sequence and is fixedly connected to the lower end of the reciprocating slider 5. The pressure sensor 7 is a hollow annular structure. A shuttle hole 10 is provided in the middle of the reciprocating slider 5 for the tailless arrow 2 to pass through. A positioning ring groove 15 for installing the compression spring 6 is provided in the middle of one side of the reciprocating slider 5. The end of the compression spring 6 is plugged or welded in the positioning ring groove 15. A positioning convex sleeve 16 is arranged on the periphery of the pressure receiving part of the pressure sensor 7. The other end of the compression spring 6 is movably mounted in the positioning convex sleeve 16. The end of the compression spring 6 presses against the pressure receiving part of the pressure sensor 7. The compression spring 6 is a force storage element that provides power for archery. Although the compression spring 6 has a certain pre-pressure during installation, it is not enough to ensure that it is in a relatively stable assembly state when rebounding after storing force. It is particularly important to insert or weld the end of the compression spring 6 into the positioning ring groove 15. It should be noted here that the parts are selected and replaced according to the assembly state between the compression spring 6 and the positioning ring groove 15. When the end of the compression spring 6 is fixed in the positioning ring groove 15 by welding, the reciprocating slider 5 and the compression spring 6 need to be replaced together during installation and adaptation.

[0038] Furthermore, the holding rod body 1 is a hollow rigid structure, and the wire perforations of the pressure sensor 7 are provided on one side surface of the lower end of the holding rod body 1 and on the side wall of the perforated fixing seat 3. The wires of the pressure sensor 7 are sequentially passed through the wire perforations and connected to the PC end, and the pressure sensor 7 is mounted in the perforated fixing seat 3 and fixed by glue. The holding rod body 1 is made of stainless steel, and the hollow design not only saves materials but also prevents overweight. The hollow structure can also facilitate wire embedding, further protecting the wires of the pressure sensor 7 from damage.

[0039] The reciprocating slider 5 is provided with a linear sleeve, and the reciprocating slider 5 is slidably sleeved on the two slide bars 4 through the linear sleeve. The two slide bars 4 are perpendicular to the front side of the perforated fixing seat 3, and the shuttle hole 10 is coaxially arranged with the perforation opened in the middle of the perforated fixing seat 3. The design of the linear sleeve mainly plays a role in reducing friction resistance and preventing direct wear between the reciprocating slider 5 and the slide bar 4, so as to ensure that the reciprocating slider 5 can adapt to long-term installation, adjustment and replacement. The coaxial setting is to enable the tailless arrow 2 to be shot smoothly and without resistance when the arrow is actually shot. It should be pointed out here that the diameter of the tailless arrow 2 is 1 / 2 to 2 / 3 of the shuttle hole 10 and the perforation.

[0040] The present embodiment mainly limits the pop-up position of the reciprocating slider 5 by the length of the tension rope 9. During installation and adjustment, it is more convenient to replace the compression spring 6 by inserting the end of the compression spring 6 into the positioning ring groove 15. If the end of the compression spring 6 is welded into the positioning ring groove 15, it is necessary to loosen the two ends of the tension rope 9 from the reciprocating slider 5, and the replacement process is relatively cumbersome. The connection method between the two ends of the tension rope 9 and the reciprocating slider 5 can be to pierce the tension rope 9, wrap it around, and fix the rope head and the tension rope 9 through a locking buckle to put it into the connecting holes at the upper and lower ends of the reciprocating slider 5, or to clamp the two ends of the tension rope 9 in the connecting holes at the upper and lower ends of the reciprocating slider 5 by screws or plugging wires.

[0041] Principle of the present invention: The present invention mainly utilizes the elasticity of the compression spring 6 to provide a kinetic energy storage element for archery. The reciprocating slider 5 is driven by the traction tension rope 9 to squeeze the compression spring 6. Since one end of the compression spring 6 presses on the pressure sensor 7, the change in the size of the spring pressure can be monitored in real time, and the specific pressure number and pressure curve graph are displayed on the evaluation software interface of the PC. The holding rod body 1 is non-elastic and cannot store energy. The pulley 8 only changes the pulling direction of the traction tension rope 9, and does not change the size of the force. When the traction tension rope 9 drives the reciprocating slider 5 to squeeze the compression spring 6 to store energy, the tension rope 9 is instantly released, and the tailless arrow 2 is accelerated to shoot during the rebound process of the tension rope 9, and the compression spring 6 is reset at the same time, completing a launch process. It should be noted that the pressure sensor 7 and the PC-side software plug-in used in conjunction with it can be purchased on the market under the existing technology.
