Abstract

This invention discloses a pawl structure for a climbing machine, including a fixed ring, connecting rings on both sides of the fixed ring, a bearing mounted on the outer side of the connecting ring, and an mounting ring mounted on the outer side of the bearing. Four pairs of fixing screws are evenly threaded on the outer side of the connecting ring, and the connecting ring is fixedly connected to the fixed ring by the fixing screws. A circular plate is provided on the side of the mounting ring away from the fixed ring. After the U-shaped frame is installed on the outer side of the two sets of mounting rings, the user only needs to pull the U-shaped frame downwards to make both sets of mounting rings rotate clockwise simultaneously. Through the cooperation of the limiting post and the arc-shaped sliding groove, the four sets of pawls on the inner side of the first set of mounting rings engage with the corresponding ratchet teeth, while the four sets of pawls on the inner side of the second set of mounting rings automatically move away from the corresponding ratchet teeth. This achieves automatic and rapid switching between clockwise and counterclockwise rotation modes for the ratchet and connecting shaft.

Description

Technical Field

[0001] This invention relates to the field of climbing machine technology, specifically to a climbing machine pawl structure. Background Technology

[0002] Due to limitations imposed by outdoor spaces and climate, and in order to enhance the advantages of indoor exercise and fitness, climbing machines that can simulate the dynamics of rock climbing and mountaineering are used. These machines allow users to effectively practice the synchronized hand and foot coordination movements during rock climbing and mountaineering, thereby achieving the effect of simulating climbing and realizing the purpose of exercise and fitness. Common climbing machines are usually connected by multiple connectors, and the pawl structure is a very important component in climbing machines.

[0003] Current climbing machine pawl structures often directly restrict the ratchet on the shaft using a set of pawls. However, this method often limits the ratchet to rotating the shaft only clockwise or counterclockwise, without allowing the ratchet to freely switch between clockwise and counterclockwise rotation, thus reducing the overall functionality of the pawl structure. Furthermore, during use, the pawl structure cannot automatically restrict the ratchet to rotate counterclockwise when rotating clockwise, nor can it automatically restrict the ratchet to rotate clockwise when rotating counterclockwise. Additionally, routine maintenance and repair of the pawl structure often involves difficulties in quickly disassembling it, increasing the overall maintenance complexity. Summary of the Invention

[0004] The purpose of this invention is to provide a pawl structure for climbing machines to solve the related problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a climbing machine pawl structure, including a fixed ring, connecting rings on both sides of the fixed ring, a bearing installed on the outer side of the connecting ring, an installation ring installed on the outer side of the bearing, four pairs of fixing screws evenly threaded on the outer side of the connecting ring, the connecting ring being fixedly connected to the fixed ring by the fixing screws, a circular plate on the side of the installation ring away from the fixed ring, an installation tube installed on the inner ring of the circular plate, a connecting component on the outer side of the circular plate, a connecting shaft shared on the inner side of the two sets of installation tubes, two sets of ratchet wheels installed on the outer side of the connecting shaft, the ratchet teeth of the two sets of ratchet wheels being in opposite directions, an adjusting component cooperating with the ratchet wheels on the inner ring of the connecting ring, four sets of arc-shaped through holes evenly opened on the outer side of the circular plate, the fixing screws being located inside the arc-shaped through holes, a fixing frame installed on the top of the fixed ring, a U-shaped frame shared on the outer side of the two sets of installation rings, a first spring installed inside the U-shaped frame, the end of the first spring away from the U-shaped frame being fixedly connected to the fixing frame.

A pin is installed at the end of the first sliding block away from the second spring. Four sets of pin grooves, matching the pins, are evenly distributed on the inner ring of the mounting ring away from the fixing ring. Four sets of limiting holes are evenly distributed on the edge of the circular plate away from the fixing ring. A connecting block is installed on the side of the first sliding block away from the fixing ring, and one end of the connecting block extends to the outer side of the circular plate and is hinged to a connecting rod. A collar is fitted on the outer side of the mounting tube, and the ends of the four sets of connecting rods away from the connecting block are all hinged to the outer side of the collar.

[0007] Preferably, the adjusting assembly includes a pawl, a second sliding groove, a mounting groove, a third spring, a second sliding block, a limiting post, and an arc-shaped sliding groove. The inner ring of the connecting ring is evenly provided with four sets of second sliding grooves, and a second sliding block is provided inside the second sliding groove. A pawl that cooperates with the ratchet is installed at one end of the second sliding block near the inner ring of the connecting ring. A mounting groove is provided at the other end of the second sliding block away from the pawl, and a third spring is installed inside the mounting groove. The end of the third spring away from the pawl is fixedly connected to one end inside the second sliding groove. A limiting post is installed on the side of the second sliding block away from the fixed ring, and the limiting post extends to the outside of the connecting ring. The circular plate is evenly provided with four sets of arc-shaped sliding grooves that cooperate with the limiting post on the side near the fixed ring.

[0008] Preferably, a U-shaped handle is symmetrically installed on the outer side of the collar, and a rubber sleeve is fitted on the outer side of the U-shaped handle.

[0009] Preferably, the connecting ring has a strip-shaped through hole on the side near the circular plate that communicates with the interior of the second sliding groove, and the width of the strip-shaped through hole is greater than the diameter of the limiting post, while the limiting post extends through the strip-shaped through hole to the outside of the connecting ring.

[0010] Preferably, four sets of retaining strips are evenly installed at the outer edge of the circular plate, and four sets of retaining grooves that are adapted to the retaining strips are evenly opened on the side of the mounting ring away from the fixing ring.

[0011] Preferably, insert rods are symmetrically installed on the outer sides of the two sets of mounting rings, and insertion holes adapted to the insert rods are symmetrically opened at both ends of the bottom of the U-shaped frame, and a handrail ball is installed on the top of the U-shaped frame.

[0012] Preferably, a fixing plate is installed on the top of the fixing frame, and bolts are symmetrically threaded at the four corners of the top of the fixing plate.

[0013] Preferably, the fixing ring has four pairs of threaded holes symmetrically opened on both sides to cooperate with the fixing screws.

[0014] Compared with the prior art, the present invention provides a pawl structure for climbing machines, which has the following advantages:

[0015] 1. This invention features two sets of ratchet wheels on the connecting shaft, along with two sets of adjusting components that cooperate with the ratchet wheels. If it is necessary to control the ratchet wheels to rotate only clockwise, the first set of mounting rings is rotated clockwise. Utilizing the cooperation of the arc-shaped sliding groove and the limiting post, four sets of second sliding blocks on the inner side of the first set of mounting rings extend from the inside of the second sliding groove until the pawls on the outer side of the four sets of second sliding blocks engage with the corresponding ratchet teeth. At this point, the ratchet wheels, along with the connecting shaft, can only rotate clockwise and cannot rotate counterclockwise. Conversely, rotating the second set of mounting rings counterclockwise will cause the ratchet wheels and connecting shaft to rotate only counterclockwise and not clockwise. Simultaneously rotating the two sets of mounting rings in opposite directions will cause the eight sets of pawls to engage with the ratchet teeth of the two sets of ratchet wheels, preventing both the ratchet wheels and the connecting shaft from rotating clockwise or counterclockwise, thus completely fixing the connecting shaft. This is very suitable for the normal needs of climbing machines during use and greatly improves the functionality of the entire pawl structure.

[0016] 2. After the U-shaped frame is installed on the outside of the two sets of mounting rings, the user only needs to pull the U-shaped frame downwards to make the two sets of mounting rings rotate clockwise simultaneously. Through the cooperation of the limiting post and the arc-shaped sliding groove, the four sets of pawls on the inner side of the first set of mounting rings engage between the ratchet teeth of the corresponding ratchet, while the four sets of pawls on the inner side of the second set of mounting rings automatically move away from the corresponding ratchet. Conversely, when the downward pull of the U-shaped frame is released, the four sets of pawls on the inner side of the second set of mounting rings engage between the ratchet teeth of the corresponding ratchet, while the four sets of pawls on the inner side of the first set of mounting rings automatically move away from the corresponding ratchet. This realizes the automatic and rapid switching between the ratchet and the connecting shaft in two rotation modes: clockwise rotation and counterclockwise rotation.

[0017] 3. When maintenance and repair of the ratchet structure are required, this invention only requires pulling the collar away from the fixed ring. The collar, through the linkage of the connecting rod, forces the connecting block to drive the first sliding block to slide inside the first sliding groove. The second spring is compressed, causing the pin to leave the inside of the pin groove, thereby releasing the connection between the circular plate and the mounting ring. Then the circular plate can be removed from the inside of the mounting ring, and the ratchet and related parts can be maintained and repaired. If maintenance and repair of all parts of the ratchet structure are required, a screwdriver can be passed through the arc-shaped through hole and multiple sets of fixing screws can be unscrewed to release the fixed connection between the connecting ring and the fixed ring. At this time, the parts connected to the connecting ring and the circular plate can be maintained and repaired. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-9This invention provides a technical solution: a climbing machine pawl structure, including a fixed ring 13, connecting rings 17 on both sides of the fixed ring 13, bearings 16 mounted on the outer side of the connecting rings 17, mounting rings 7 mounted on the outer side of the bearings 16, four pairs of fixing screws 6 evenly threaded on the outer side of the connecting rings 17, the connecting rings 17 being fixedly connected to the fixed ring 13 by the fixing screws 6, a circular plate 2 being provided inside the mounting ring 7 on the side away from the fixed ring 13, and mounting tubes 5 being installed on the inner ring of the circular plate 2, a connecting assembly 8 being provided on the outer side of the circular plate 2, and the inner rings of the two sets of mounting tubes 5 being connected to the inner rings of the mounting ring 7. A connecting shaft 14 is provided on both sides. Two sets of ratchet wheels 15 are installed on the outer side of the connecting shaft 14, and the ratchet teeth of the two sets of ratchet wheels 15 are in opposite directions. An adjusting component 9 that cooperates with the ratchet wheel 15 is provided on the inner ring of the connecting ring 17. Four sets of arc-shaped through holes 11 are evenly opened on the outer side of the circular plate 2. The fixing screw 6 is located inside the arc-shaped through hole 11. A fixing bracket 1 is installed on the top of the fixing ring 13. A U-shaped bracket 4 is installed on the outer side of the two sets of mounting rings 7. A first spring 3 is installed inside the U-shaped bracket 4. The end of the first spring 3 away from the U-shaped bracket 4 is fixedly connected to the fixing bracket 1.

[0030] Further, the connecting assembly 8 includes a collar 801, a connecting rod 802, a connecting block 803, a first sliding block 804, a limiting hole 805, a second spring 806, a pin 807, a pin groove 808, and a first sliding groove 809. Four sets of first sliding grooves 809 are evenly distributed on the outer ring of the fixing ring 13, and a second spring 806 is installed at one end of each first sliding groove 809. A first sliding block 804, fixedly connected to one end of the second spring 806, is disposed inside the first sliding groove 809. The first sliding block 804 is located away from the second spring 806. The end is equipped with a pin 807. The inner ring of the mounting ring 7 is evenly provided with four sets of pin grooves 808 that are adapted to the pin 807 at the end away from the fixing ring 13. The circular plate 2 is evenly provided with four sets of limiting holes 805 at the edge position away from the fixing ring 13. The first sliding block 804 is equipped with a connecting block 803 on the side away from the fixing ring 13. One end of the connecting block 803 extends to the outside of the circular plate 2 and is hinged to a connecting rod 802. The outer side of the mounting tube 5 is fitted with a collar 801. The ends of the four sets of connecting rods 802 away from the connecting block 803 are all hinged to the outside of the collar 801.

[0031] Furthermore, the adjusting assembly 9 includes a pawl 901, a second sliding groove 902, a mounting groove 903, a third spring 904, a second sliding block 905, a limiting post 906, and an arc-shaped sliding groove 907. The inner ring of the connecting ring 17 has four sets of second sliding grooves 902 evenly spaced, and a second sliding block 905 is disposed inside each second sliding groove 902. A pawl 901 that cooperates with the ratchet 15 is mounted on one end of the second sliding block 905 near the inner ring of the connecting ring 17. The second sliding block 905 is further away from the... An installation groove 903 is provided at one end away from the pawl 901, and a third spring 904 is installed inside the installation groove 903. The end of the third spring 904 away from the pawl 901 is fixedly connected to one end inside the second sliding groove 902. A limit post 906 is installed on the side of the second sliding block 905 away from the fixed ring 13, and the limit post 906 extends to the outside of the connecting ring 17. Four sets of arc-shaped sliding grooves 907 that cooperate with the limit post 906 are evenly provided on the side of the circular plate 2 near the fixed ring 13.

[0032] Furthermore, a U-shaped handle is symmetrically installed on the outer side of the collar 801, and a rubber sleeve is fitted on the outer side of the U-shaped handle to facilitate manually pulling the collar 801 away from the fixed ring 13.

[0033] Furthermore, the connecting ring 17 has a strip-shaped through hole on the side near the circular plate 2 that communicates with the interior of the second sliding groove 902. The width of the strip-shaped through hole is greater than the diameter of the limiting post 906. The limiting post 906 extends through the strip-shaped through hole to the outside of the connecting ring 17. This not only does not affect the movement of the limiting post 906, but also limits the movement distance of the limiting post 906.

[0034] Furthermore, four sets of clips 10 are evenly installed at the outer edge of the circular plate 2. Four sets of slots 12 that are compatible with the clips 10 are evenly opened on the side of the mounting ring 7 away from the fixing ring 13. When installing the circular plate 2, the clips 10 are first inserted into the corresponding slots 12, so that the pin 807 and the pin groove 808 can be aligned.

[0035] Furthermore, insert rods are symmetrically installed on the outer sides of the two sets of mounting rings 7, and insertion holes that match the insert rods are symmetrically opened at both ends of the bottom of the U-shaped frame 4. Handrail balls are installed on the top of the U-shaped frame 4 to facilitate the disassembly or installation of the U-shaped frame 4.

[0036] Furthermore, a fixing plate is installed on the top of the fixing frame 1, and bolts are symmetrically threaded at the four corners of the top of the fixing plate, which facilitates the fixing of the entire ratchet structure to the main frame of the climbing machine.

[0037] Furthermore, four pairs of threaded holes that cooperate with the fixing screws 6 are symmetrically provided on both sides of the fixing ring 13, so as to facilitate the fixing of the connecting ring 17 and the fixing ring 13 by the fixing screws 6.

[0038] Example 1, such as Figure 4-5 As shown, when maintenance and repair of the ratchet structure are required, simply pull the collar 801 away from the fixed ring 13. The collar 801, through the linkage of the connecting rod 802, forces the connecting block 803 to drive the first sliding block 804 to slide inside the first sliding groove 809. The second spring 806 is compressed, causing the pin 807 to leave the inside of the pin groove 808, thereby releasing the connection between the round plate 2 and the mounting ring 7. Then the round plate 2 can be removed from the inside of the mounting ring 7, and the ratchet 15 and related parts can be maintained and repaired. If maintenance and repair of all parts of the ratchet structure are required, a screwdriver can be passed through the arc-shaped through hole 11 and multiple sets of fixing screws 6 can be unscrewed to release the fixed connection between the connecting ring 17 and the fixed ring 13. At this time, the parts connected to the connecting ring 17 and the round plate 2 can be maintained and repaired.

[0039] Example 2, as Figure 4-5 As shown, if it is necessary to control the ratchet 15 to rotate only clockwise, the first set of mounting rings 7 is rotated clockwise. Utilizing the cooperation of the arc-shaped sliding groove 907 and the limiting post 906, the four sets of second sliding blocks 905 on the inner side of the first set of mounting rings 7 extend from the inside of the second sliding groove 902 until the pawls 901 on the outer side of the four sets of second sliding blocks 905 engage with the corresponding ratchet teeth of the ratchet 15. At this time, the ratchet 15, along with the connecting shaft 14, can only rotate clockwise and cannot rotate counterclockwise. Conversely, rotating the second set of mounting rings 7 counterclockwise will cause the ratchet 15 and the connecting shaft 14 to rotate only counterclockwise and cannot rotate clockwise. At the same time, rotating the two sets of mounting rings 7 in opposite directions will cause the eight pawls 901 to engage with the ratchet teeth of the two sets of ratchet 15 respectively, preventing the two sets of ratchet 15 and the connecting shaft 14 from rotating either clockwise or counterclockwise, thus completely fixing the connecting shaft 14.

[0040] Working principle: If it is necessary to control the ratchet 15 to rotate only clockwise, the first set of mounting rings 7 is rotated clockwise. Utilizing the cooperation of the arc-shaped sliding groove 907 and the limiting post 906, the four sets of second sliding blocks 905 on the inner side of the first set of mounting rings 7 extend from the inside of the second sliding groove 902 until the pawls 901 on the outer side of these four sets of second sliding blocks 905 engage with the corresponding ratchet teeth of the ratchet 15. At this point, the ratchet 15, along with the connecting shaft 14, can only rotate clockwise and cannot rotate counterclockwise. Conversely, rotating the second set of mounting rings 7 counterclockwise will cause the ratchet 15 and the connecting shaft 14 to rotate only counterclockwise and not clockwise, while simultaneously engaging both sets of mounting rings 7. Rotating in the opposite direction will cause the eight sets of pawls 901 to engage between the ratchet teeth of the two sets of ratchet wheels 15, preventing the two sets of ratchet wheels 15 and the connecting shaft 14 from rotating clockwise or counterclockwise, thus completely fixing the connecting shaft 14. After installing the U-shaped bracket 4 on the outside of the two sets of mounting rings 7, the user only needs to pull the U-shaped bracket 4 downwards. The first spring 3 is stretched and stores elastic potential energy, which allows the two sets of mounting rings 7 to rotate clockwise simultaneously. Through the cooperation of the limiting post 906 and the arc-shaped slide groove 907, the four sets of pawls 901 on the inner side of the first set of mounting rings 7 engage between the ratchet teeth of the corresponding ratchet wheels 15, while the second set of mounting rings 7... The four sets of pawls 901 on the inner side automatically move away from the corresponding ratchet 15. Conversely, releasing the downward pull on the U-shaped bracket 4 causes the four sets of pawls 901 on the inner side of the second set of mounting rings 7 to engage between the ratchet teeth of the corresponding ratchet 15, while the four sets of pawls 901 on the inner side of the first set of mounting rings 7 automatically move away from the corresponding ratchet 15. This achieves automatic and rapid switching between the two rotation modes of the ratchet 15 and the connecting shaft 14, which can only rotate clockwise and counterclockwise. When maintenance or repair of the pawl structure is required, simply pull the collar 801 away from the end of the fixed ring 13. The collar 801, through the linkage of the connecting rod 802, forces the connecting block 803 to move. The first sliding block 804 slides inside the first sliding groove 809, and the second spring 806 is compressed, causing the pin 807 to leave the inside of the pin groove 808, thereby releasing the connection between the circular plate 2 and the mounting ring 7. Then the circular plate 2 can be removed from the inside of the mounting ring 7, and the ratchet 15 and related parts can be maintained and repaired. If it is necessary to maintain and repair all parts of the ratchet structure, a screwdriver can be passed through the arc-shaped through hole 11 and the multiple sets of fixing screws 6 can be unscrewed to release the fixed connection between the connecting ring 17 and the fixing ring 13. At this time, the parts connected to the connecting ring 17 and the circular plate 2 can be maintained and repaired.
