Description

Technical Field

[0001] This invention belongs to the field of sports equipment technology, specifically a high-safety three-dimensional woven pole for pole vaulting and its manufacturing method. Background Technology

[0002] Pole vaulting is an athletics competition in which athletes use the elasticity of a pole to complete the approach run, take-off, and clearance of the pole. As the core equipment of this event, the performance of the pole directly determines the athlete's performance and safety. Modern competitive poles are mostly made of hollow poles with high elasticity fiber composite materials. These poles have excellent elastic deformation capacity, structural toughness, and tensile strength, and can adapt to the large bending force required by athletes during take-off.

[0003] In actual use, after an athlete uses the pole vault to take off, the pole is prone to tilting due to imbalance of force, which can cause the top of the pole to make a hard impact with the athlete's torso. Currently, the protection at the top of the pole is mostly a simple elastic pad structure, which has limited cushioning and energy absorption effect and cannot effectively dissipate the hard impact force at the top, which can easily cause limb injuries to athletes and affect the continuity of the athlete's subsequent take-off movements. Summary of the Invention

The self-inflating buffer includes a fixed sleeve fixedly connected inside the high jump pole. A concave plate is provided inside the fixed sleeve. An upper pressure plate is fixedly connected to the top of the concave plate. An air bladder is fixedly connected to the upper pressure plate.

A transmission component connected to the lower pressure plate is provided on the toothed rod. A chassis is fixedly connected to the bottom of the concave plate. A spring is fixedly connected to the bottom of the chassis. The bottom of the spring is fixedly connected to the inside of the fixed sleeve. As the upper pressure plate moves downward / upward, it drives the transmission component to move the lower pressure plate upward / downward, thereby causing the airbag to inflate / not inflate. The buffer locking element is located inside the fixed sleeve to prevent the upper pressure plate from springing back after buffering.

[0005] In the above technical solution, preferably, the transmission component includes a support plate sleeved on the rack, the support plate being fixedly connected inside the fixed sleeve, two turntables being symmetrically fixedly connected on the rack, a rotating plate being hinged to the turntable via a shaft, the top of the rotating plate being hinged to the bottom of the lower pressure plate via a shaft, and a toothed plate that meshes with the rack being fixedly connected inside the concave plate.

[0006] In the above technical solution, preferably, a support ring is fixedly connected inside the fixed sleeve, the top of the support ring is in contact with the bottom of the lower pressure plate, the surface of the sealing gasket is in contact with the inner wall of the fixed sleeve, and the surface of the concave plate is in contact with the inner wall of the sealing gasket.

[0007] In the above technical solution, preferably, the buffer locking component includes a square groove formed inside the support plate, a guide rod fixedly connected inside the square groove, an inclined plate slidably sleeved on the guide rod, a second spring located outside the guide rod fixedly connected to one side of the inclined plate, one end of the second spring fixedly connected inside the square groove, an inclined groove formed on the toothed rod, one end of the inclined plate extending into the inclined groove, and an unlocking component provided inside the fixed sleeve.

[0008] In the above technical solution, preferably, the unlocking component includes an L-shaped plate fixedly connected to the inclined plate, a synchronization plate fixedly connected to the L-shaped plate is provided inside the fixing sleeve, the synchronization plate is sleeved on the support plate, a push rod is fixedly connected to one side of the synchronization plate, and the end of the push rod away from the synchronization plate extends through to one side of the high jump pole.

[0009] In the above technical solution, preferably, two limiting blocks are symmetrically fixedly connected to the inclined plate, and two limiting grooves are symmetrically opened inside the square groove, with the limiting blocks slidably connected inside the limiting grooves.

[0010] In the above technical solution, preferably, an air supply component is provided on one side of the fixed sleeve. The air supply component includes a ventilator fixedly connected inside the fixed sleeve. A spring is fixedly connected inside the ventilator. A pressure rod is fixedly connected to one end of the spring. An air guide groove is provided on the pressure rod. The surface of the pressure rod is in contact with the inner wall of the ventilator.

[0011] In the above technical solution, preferably, a sealing ring is fixedly connected to one side of the pressure rod, and one side of the sealing ring is in contact with the inner wall of the ventilator.

[0012] In the above technical solution, preferably, two positioning plates are symmetrically fixedly connected inside the fixing sleeve, and the concave plate and the chassis are both sleeved on the positioning plates.

[0013] A method for manufacturing a high-safety three-dimensional woven pole for pole vaulting includes the following steps: S1: Select a high-elasticity high jump pole as the blank, cut it to a fixed length, grind it finely, and then process the self-inflating buffer installation cavity. Clean and dry it before use. S2: Fix the high jump pole to the three-dimensional weaving equipment station, and use high elastic fiber yarn to cross-weave along the high jump pole to form an elastic woven net, so that the elastic woven net fits tightly with the high jump pole; S3: Select high-strength lightweight alloy to process the metal parts of the self-inflating buffer and buffer locking parts, select stainless steel to make spring one and spring two, and finely grind and deburr all parts; S4: First, assemble the self-inflating buffer and buffer locking components in modules, then fix them in the mounting cavity of the high jump pole base. After testing the sliding, transmission and inflation sealing performance, complete the overall assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses the downward movement of the upper pressure plate to drive the transmission components in conjunction with the rack and pinion to push the lower pressure plate upward via the turntable and rotating plate, thereby achieving self-inflation of the airbag. This increases the contact area with the athlete's torso and disperses the impact force. At the same time, the chassis directly buffers the impact force through the springs. This double buffering and energy absorption reduces the instantaneous hard impact force of the high jump pole on the athlete's torso. The buffering and energy absorption effect is significant, effectively avoiding limb injuries. It is suitable for repeated use, has high safety, and is suitable for pole vaulting competition and training scenarios.

[0015] Furthermore, the upper pressure plate is prone to rebound after being impacted and shifted downwards for cushioning, which could cause a secondary impact on the athlete's torso, posing a certain safety hazard. However, through the design of the square groove, guide rod, and inclined plate in the cushioning locking component, the inclined plate can effectively lock the position of the upper pressure plate after it is engaged in the inclined groove, avoiding secondary impact caused by the rebound of the upper pressure plate. The unlocking component can drive the inclined plate to slide along the guide rod, releasing the lock on the rack, allowing the elastic force of the spring to drive the chassis, concave plate, and upper pressure plate to reset, thereby restoring the airbag to its initial state. This ensures both the locking protection effect after cushioning and the ability to quickly unlock and reset, taking into account both safety protection and structural practicality.

[0016] Furthermore, airbags are prone to micro-leakage after long-term use, resulting in insufficient air pressure after inflation, a significant reduction in buffering and energy absorption effects, and an inability to guarantee sufficient contact area. However, through the design of the air supply component, including the ventilator, spring, and pressure rod, when the air pressure inside the airbag decreases, the pressure rod can be pushed with a screwdriver. The pressure rod moves along the inner wall of the ventilator and compresses the spring, allowing outside air to enter the airbag through the air guide groove on the pressure rod, thus replenishing the air supply. This ensures that the airbag always maintains the preset air pressure, ensuring that it can provide sufficient contact area after expansion and stably exert its buffering and energy absorption effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: As Figures 1 to 4 As shown, this invention provides a high-safety three-dimensional woven pole vaulting system and its manufacturing method, including a high jump pole 1, an elastic woven mesh sleeve 2 fixedly connected to the high jump pole 1, and further comprising: The self-inflating buffer 3 is installed inside the high jump pole 1 to improve the safety of the high jump pole 1; The self-inflating buffer 3 includes a fixed sleeve 31 fixedly connected inside the high jump pole 1. A concave plate 32 is provided inside the fixed sleeve 31. An upper pressure plate 33 is fixedly connected to the top of the concave plate 32. An airbag 34 is fixedly connected to the upper pressure plate 33. The bottom of the airbag 34 is fixedly connected to the high jump pole 1. A lower pressure plate 35 is slidably connected inside the fixed sleeve 31. A sealing gasket 36 is fixedly connected to the top of the lower pressure plate 35. A toothed rod 37 is provided inside the fixed sleeve 31. A transmission component 38 connected to the lower pressure plate 35 is provided on the toothed rod 37. A chassis 39 is fixedly connected to the bottom of the concave plate 32. A spring 310 is fixedly connected to the bottom of the chassis 39. The bottom of the spring 310 is fixedly connected inside the fixed sleeve 31. As the upper pressure plate 33 moves downward / upward, the drive transmission component 38 drives the lower pressure plate 35 upward / downward, thereby causing the airbag 34 to inflate / not inflate. The buffer locking element 4 is located inside the fixed sleeve 31 to prevent the upper pressure plate 33 from rebounding after buffering.

[0021] Specifically, the high jump pole 1 is a carbon fiber pole, which is a mature technology application; the silicone airbag 34 is made of high elastic silicone, which can increase the contact area with the user's skin after expansion, effectively disperse the impact force and resist tearing; the upper pressure plate 33 has rounded corners to avoid scraping the athlete's torso during impact, and at the same time adapts to the airbag 34 for close installation.

[0022] like Figures 2 to 5 As shown, the transmission component 38 includes a support plate 381 sleeved on the rack 37. The support plate 381 is fixedly connected inside the fixed sleeve 31. Two turntables 382 are symmetrically fixedly connected to the rack 37. A rotating plate 383 is hinged to the turntable 382 via a shaft. The top of the rotating plate 383 is hinged to the bottom of the lower pressure plate 35 via a shaft. A toothed plate 384 that meshes with the rack 37 is fixedly connected inside the concave plate 32.

[0023] Specifically, the support plate 381 provides vertical support and guidance for the toothed rod 37. When the toothed rod 37 is subjected to force, it drives the two symmetrical turntables 382 on it to rotate synchronously. The turntables 382 pull the hinged rotating plate 383 to swing and move upward through the shaft. The rotating plate 383 drives the lower pressure plate 35 to slide vertically along the inner wall of the fixed sleeve 31, which can accurately drive the lower pressure plate 35 to move up and down, ensuring that the airbag 34 completes inflation and expansion in time with the thumping action of the upper pressure plate 33, and the structure has strong stability.

[0024] like Figure 2 As shown, a support ring 5 is fixedly connected inside the fixed sleeve 31. The top of the support ring 5 is in contact with the bottom of the lower pressure plate 35, the surface of the sealing gasket 36 is in contact with the inner wall of the fixed sleeve 31, and the surface of the concave plate 32 is in contact with the inner wall of the sealing gasket 36.

[0025] Specifically, the support ring 5 can support the lower pressure plate 35 and limit its downward stroke, ensuring the accuracy of the transmission component 38 driving the lower pressure plate 35 to move upward; the sealing gasket 36 can ensure the airtightness of the airbag 34 and improve the structural stability of the self-inflating buffer component 3.

[0026] like Figures 3 to 7 As shown, the buffer locking component 4 includes a square groove 41 formed inside the support plate 381. A guide rod 42 is fixedly connected inside the square groove 41. An inclined plate 43 is slidably sleeved on the guide rod 42. A second spring 44 located outside the guide rod 42 is fixedly connected to one side of the inclined plate 43. One end of the second spring 44 is fixedly connected inside the square groove 41. An inclined groove 45 is formed on the toothed rod 37. One end of the inclined plate 43 extends into the inclined groove 45. An unlocking component 46 is provided inside the fixed sleeve 31.

[0027] Specifically, after the inclined plate 43 is engaged in the inclined groove 45, it can effectively lock the position of the upper pressure plate 33, avoiding secondary impact caused by the rebound of the upper pressure plate 33; the unlocking component 46 can drive the inclined plate 43 to slide along the guide rod 42, release the lock on the toothed rod 37, and allow the elastic force of the spring 310 to drive the chassis 39, the concave plate 32 and the upper pressure plate 33 to reset, thereby restoring the airbag 34 to its initial state. This ensures both the locking protection effect after buffering and the ability to quickly unlock and reset, taking into account both safety protection and structural practicality.

[0028] like Figures 2 to 5 As shown, the unlocking component 46 includes an L-shaped plate 461 fixedly connected to the inclined plate 43. The inside of the fixing sleeve 31 is provided with a synchronization plate 462 fixedly connected to the L-shaped plate 461. The synchronization plate 462 is sleeved on the support plate 381. A push rod 463 is fixedly connected to one side of the synchronization plate 462. The end of the push rod 463 away from the synchronization plate 462 extends through to one side of the high jump support bar 1.

[0029] Specifically, when it is necessary to engage the locking of the inclined plate 43, the push rod 463 can be pushed with a screwdriver. The push rod 463 drives the synchronous plate 462 to slide laterally along the support plate 381. The synchronous plate 462 pulls the L-shaped plate 461 fixed to it to move synchronously, thereby pulling the inclined plate 43 to slide along the guide rod 42 and compressing the second spring 44, so that the inclined plate 43 disengages from the inclined groove 45 of the toothed rod 37, releasing the lock on the toothed rod 37. This can quickly release the locking state of the upper pressure plate 33, and, together with the first spring 310, realize the reset of each component of the self-inflating buffer 3.

[0030] like Figure 7 As shown, two limiting blocks 6 are symmetrically fixedly connected to the inclined plate 43, and two limiting grooves 7 are symmetrically opened inside the square groove 41. The limiting blocks 6 are slidably connected inside the limiting grooves 7.

[0031] Specifically, the limiting block 6 and the limiting groove 7 can provide precise guidance for the lateral sliding of the tilting plate 43, prevent the tilting plate 43 from deviating or shaking, and ensure that it can stably and accurately engage or disengage from the tilting groove 45 of the toothed rod 37, avoiding component misalignment from affecting the locking effect.

[0032] like Figure 1 and Figure 6 As shown, a gas supply component 8 is provided on one side of the fixed sleeve 31. The gas supply component 8 includes a ventilator 81 fixedly connected inside the fixed sleeve 31. A spring 82 is fixedly connected inside the ventilator 81. A pressure rod 83 is fixedly connected to one end of the spring 82. An air guide groove 84 is provided on the pressure rod 83. The surface of the pressure rod 83 is in contact with the inner wall of the ventilator 81.

[0033] Specifically, when the air pressure inside the airbag 34 decreases, the pressure rod 83 can be pushed with a screwdriver. The pressure rod 83 moves along the inner wall of the ventilator 81 and compresses the spring 82. Outside air enters the airbag 34 through the air guide groove 84 on the pressure rod 83 to achieve air replenishment. This ensures that the airbag 34 always maintains the preset air pressure, ensuring that it can provide sufficient contact area after expansion and stably perform the buffering and energy absorption effect.

[0034] like Figure 6 As shown, a sealing ring 9 is fixedly connected to one side of the pressure rod 83, and one side of the sealing ring 9 is in contact with the inner wall of the ventilator 81.

[0035] Specifically, the sealing ring 9 can seal the gap between the pressure rod 83 and the ventilator 81, effectively preventing air from leaking from the gap between the pressure rod 83 and the ventilator 81, and ensuring the airtightness of the air supply component 8.

[0036] like Figure 2 As shown, the fixed sleeve 31 has two symmetrical fixed connections inside, and the concave plate 32 and the base plate 39 are both sleeved on the positioning plate 10.

[0037] Specifically, two sleeve plates are symmetrically fixedly connected to the fixed sleeve 31. The sleeve plates are fitted onto the concave plate 32 and can guide the concave plate 32. The positioning plate 10 can provide guidance and limit for the vertical movement of the two, effectively preventing the concave plate 32 and the chassis 39 from shifting and shaking during the up and down sliding process, and ensuring the accuracy of the action when the upper pressure plate 33 is pushed down by the impact and the spring 310 elastically resets.

[0038] Working principle and usage process of this invention: The athlete first practices pole vaulting using the high jump pole 1. When the top of the high jump pole 1 is struck by the athlete's torso, the upper pressure plate 33 is forced to move downward, causing the concave plate 32 to slide down synchronously along the two positioning plates 10 inside the fixed sleeve 31. The base plate 39 at the bottom of the concave plate 32 compresses the spring 310, and the spring 310 directly buffers the axial impact force. At the same time, the concave plate 32 pushes the toothed plate 384 to move downward, the toothed plate 384 drives the toothed bar 37 to rotate, the toothed bar 37 drives the two turntables 382 to rotate synchronously, the turntables 382 drive the rotating plate 383 to swing and move upward through the shaft, the rotating plate 383 drives the lower pressure plate 35 to move upward along the inner wall of the fixed sleeve 31, as the lower pressure plate 35 moves upward, the airbag 34 is squeezed and inflated, greatly increasing the contact area with the athlete's torso, converting the instantaneous hard stab force into uniform pressure, forming a double buffer energy absorption with the spring 310; During the buffering process, the rack 37 continues to rotate, and the inclined plate 43 slides along the surface of the guide rod 42 and gets stuck in the inclined groove 45 of the rack 37 under the elastic force of the second spring 44, preventing the rack 37 from rotating back and locking the position of the upper pressure plate 33 after buffering to avoid rebound and secondary impact.

[0039] Example 2: A method for manufacturing a high-safety three-dimensional woven pole for pole vaulting, comprising the following steps: S1: Select the high-elasticity high jump support pole 1 as the blank, cut it to a fixed length, grind it finely, and then process the self-inflating buffer 3 mounting cavity. Clean and dry it for later use. S2: Fix the high jump pole 1 to the three-dimensional weaving equipment station, and use high elastic fiber yarn to cross-weave along the high jump pole 1 to form an elastic woven net sleeve 2, so that the elastic woven net sleeve 2 fits tightly with the high jump pole 1. S3: Select high-strength lightweight alloy to process the metal parts of self-inflating buffer 3 and buffer locking part 4, select stainless steel material to make spring 1 310 and spring 2 44, and finely grind and deburr all parts. S4: First, modularly assemble the self-inflating buffer 3 and the buffer locking 4, then fix them in the mounting cavity of the high jump pole 1 base. After testing the sliding, transmission and inflation sealing performance, complete the overall assembly.
