Description

Technical Field

[0001] The present invention relates to the technical field of harness supplies, and particularly to a self-locking safety stirrup. Background Art

[0002] Since the traditional stirrup appeared, it mainly relies on a simple mechanical structure to fix the rider's foot. In most existing stirrup designs, the connection between the stirrup head and the stirrup frame is usually achieved through a buckle, a spring or a simple clamping device. However, these traditional designs often do not take into account the changes in the foot under external forces during riding. Especially when the horse is running at high speed, jolting violently or the rider makes a sudden movement, the stirrup head is likely to fall off, causing the rider's foot to accidentally disengage from the stirrup.

[0003] The biggest drawback of this design is that it cannot effectively prevent the foot from falling off. Especially when the horse is running at a relatively fast speed or encountering an unstable road surface, the rider's foot will be dislodged from the stirrup due to sudden vibrations, jolts or falls. If the stirrup does not have a good fixing mechanism, the rider may not only lose control of the horse, but also may suffer serious accidents such as falls or collisions. For example, when the horse suddenly turns or accelerates violently, the rider's foot may disengage due to inertia or an unstable stirrup design, resulting in the rider falling off and increasing the risk of major accidents.

[0004] Most existing stirrup designs do not have a self-locking function, which makes it impossible for the rider to react or correct in time when the foot is unstable or falls off during riding, increasing potential safety hazards. Even if some stirrup designs use springs or buckles to improve stability, these traditional designs often cannot cope with extreme situations during long-term use or high-intensity riding, resulting in the stirrup being easily loosened or losing its fixing effect during frequent riding jolts.

[0005] Traditional stirrups lack a self-locking function and cannot effectively prevent the foot from disengaging from the stirrup, which poses a serious threat to the safety of riders. Therefore, there is an urgent need for a new stirrup design that can keep the foot stable during riding and has a self-locking function to ensure that the rider can ride safely under various complex conditions and avoid accidents caused by foot detachment. Summary of the Invention

[0006] The present invention provides a self-locking safety stirrup. By changing the magnetic pole direction of the commutation magnet; when in the open state, the magnetic poles of the commutation magnet and the opening and closing magnet are the same. The same magnetic poles cause the commutation magnet to repel the stirrup head and the opening and closing magnet out of the stirrup frame, and the locking plate is in the unlocked state in the stirrup frame, facilitating the rider's foot to disengage from the stirrup; when in the closed state, the magnetic poles of the commutation magnet are different from those of the opening and closing magnet. The two magnetic poles attract each other. Under the attracting magnetic force, the opening and closing magnet causes the stirrup head to stick to the commutation magnet, and the locking contact is stuck in the locking groove of the stirrup head, preventing the stirrup head from detaching from the stirrup frame.

[0069] Working principle: When the rider's foot is placed in the stirrup and the foot is lifted sideways, it presses the hydraulic trigger head 401. When the hydraulic trigger head 401 is pressed, the hydraulic trigger head 401 drives the hydraulic piston 405 to slide in the hydraulic pipe 404. The hydraulic piston 405 compresses the hydraulic return spring 406, and the hydraulic oil in the hydraulic pipe 404 flows out from the hydraulic delivery pipe 402 and flows into the hydraulic hose 403 and the delay power cylinder 501.

[0070] The hydraulic oil in the delay power cylinder 501 accumulates continuously, pushing the power push rod 502 and the delay piston 509 to move. The power push rod 502 extends outwards, and the delay piston 509 compresses the power return spring 5010. The movement of the power push rod 502 extending outwards drives one end of the extension plate 503, and the movement of the extension plate 503 drives the movement of the power plate 504.

[0071] The movement of the power plate 504 drives the movement of the delay gear set 5011 and the delay clamping plate 5012. The delay gear set 5011 drives the rotation of the delay gear 5028. The rotation of the delay gear 5028 drives the rotation of the delay rotating shaft 5013 and the incomplete bevel gear 5014. At the contact between the toothless area of the incomplete bevel gear 5014 and the delay bevel gear 5016, the delay bevel gear 5016 does not rotate at this time. It is not until the tooth area of the incomplete bevel gear 5014 meshes with the teeth of the delay bevel gear 5016 that the rotation of the incomplete bevel gear 5014 drives the rotation of the delay bevel gear 5016. The rotation of the delay bevel gear 5016 drives the rotation of the delay rotating rod 506. The rotation of the delay rotating rod 506 drives the delay cam 507 to clamp the hydraulic hose 403, so as to reduce the internal area of the pipe and thus reduce the flow rate of the hydraulic oil in the hydraulic delivery pipe 402, increase the duration of the liquid flow. The delay gear 5028 disengages from the delay gear set 5011, and one side of the hexagonal column 5015 abuts tightly against the delay clamping plate 5012, so that the delay cam 507 supports and clamps the hydraulic hose 403.

[0072] The movement of the power plate 504 drives the displacement of the auxiliary sliding rod 5023 and the limit abutting piece 5024. The auxiliary sliding rod 5023 moves outward beyond the auxiliary pipe 5022. The auxiliary sliding rod 5023 drives the auxiliary piston 5025 to move in the auxiliary pipe 5022. The auxiliary piston 5025 compresses the auxiliary return spring 5026. The auxiliary piston 5025 generates negative pressure in the auxiliary pipe 5022 and extracts the hydraulic oil in the side moving pipe 809 through the auxiliary liquid pipe 5027. The side moving rod 8010 retracts into the side moving pipe 809. The retracted side moving rod 8010 pulls the movable plate 808 to move. The movable plate 808 drives the locking contact 803 to retract, so that the locking contact 803 disengages from the chuck 6, and the movable plate 808 displaces in the locking movable groove 806.

[0073] In the displacement direction of the locking contact 803 disengaging from the chuck 6, the locking contact 803 compresses the locking return spring 807. The movement of the movable plate 808 drives the synchronous movement of the reversing plate 8013. The first reversing gear 8016 drives the rotation of the first reversing gear 8016 in the state of the movement of the reversing plate 8013. The rotation of the first reversing gear 8016 drives the rotation of the first transmission rod 8015. The rotation of the first transmission rod 8015 drives the rotation of the transmission bevel gear pair 8018. The rotation of the transmission bevel gear pair 8018 drives the rotation of the second transmission rod 8017 and the first one-way misaligned block 8019. The rotation of the first one-way misaligned block 8019 abuts against the rotation of the second one-way misaligned block 8022. The rotation of the second one-way misaligned block 8022 drives the rotation of the misaligned rod 8021 and the third transmission rod 8020.

[0074] The rotation of the third transmission rod 8020 drives the rotation of the offset gear 8024, and the rotation of the offset gear 8024 drives the reversing slider 8026 and the second reversing gear set 8027 to slide along the reversing slider 8025. The reversing slider 8026 is located to compress the reversing reset spring 8035, and the reversing slider 8026 drives the reversing rotating rod 804 and the reversing cam 8034 to slide in the reversing sliding groove 8033. During the displacement of the reversing rotating rod 804, the reversing rotating plate 8028 on the reversing rotating rod 804 encounters The reversing swing plate 8031 is restricted by the limit plate 8029 and the reversing torsion spring 8032, so that the reversing rotating plate 8028 drives the reversing rotating rod 804 to rotate. The two reversing swing plates 8031 cause the reversing rotating rod 804 to rotate twice. The rotation of the reversing rotating rod 804 drives the reversing magnet 805 to change the magnetic pole. The first reversing gear 8016 disengages from the second reversing tooth group 8027 area of the reversing plate 8013, and the reversing reset spring 8035 resets the reversing slider 8026.

[0075] The reset reversing slider 8026 and the second reversing gear set 8027 drive the offset gear 8024 to rotate in the opposite direction, and the offset gear 8024 that rotates in the opposite direction drives the third transmission rod 8020, the offset rod 8021 and the second one-way offset block 8022 to rotate in the opposite direction, and the second one-way offset block 8022 is offset from the first one-way offset block 8019, and the offset spring 8023 supports the offset rod 8021 and the second one-way offset block 8022 to be elastically offset from the first one-way offset block 8019; the reset reversing slider 8026 drives the reversing rotating rod 804 to reset, and the reversing rotating rod 804 encounters the reversing rotating rod 804 The pendulum plate 8031, the reversing pendulum plate 8031 rotates on the torsion bar 8030, and the reversing pendulum plate 8031 twists the reversing torsion spring 8032 to stagger the reversing rotating rod 804. After the reversing rotating rod 804 leaves the reversing pendulum plate 8031, the reversing torsion spring 8032 drives the reversing pendulum plate 8031 to reset, and the reversing rotating rod 804 drives the reversing magnet 805 to quickly approach the opening and closing magnet 7. At this time, the reversing magnet 805 has the same magnetic pole as the opening and closing magnet 7. The same magnetic pole makes the reversing magnet 805 repel the clamp 6 and the opening and closing magnet 7 out of the stirrup frame 1, and the locking curved plate 3 is unlocked at the stirrup frame 1, which is convenient for the rider's foot to leave the stirrup.

[0076] The locking reset spring 807 drives the locking contact 803 to reset, the locking contact 803 drives the movable plate 808 to reset, the reset of the movable plate 808 drives the reset of the reversing plate 8013, the reset movement direction of the reversing plate 8013 drives the first reversing tooth group 8014 to reset, the reset of the first reversing tooth group 8014 drives the first reversing gear 8016 to rotate in the opposite direction, the reverse rotation of the first reversing gear 8016 drives the first transmission rod 8015, the transmission bevel gear pair 8018, the second transmission rod 8017 and the first one-way offset block 8019 to rotate in the opposite direction, and the first one-way offset block 8019 and the second one-way offset block 8022 are offset from each other.

[0077] The power return spring 5010 and the auxiliary power return spring 5026 return to their original positions, the power push rod 502 returns to its original position within the delay power cylinder 501, and the auxiliary power slide rod 5023 returns to its original position within the auxiliary power tube 5022; the hydraulic return spring 406 returns the hydraulic piston 405 and the hydraulic trigger head 401 to their original positions, and the hydraulic trigger head 401 extends out of the hydraulic tube 404 and returns to the initial state.

[0078] The reversing magnet 805 and the opening and closing magnet 7 are in a state of like-pole repulsion, so that the chuck 6 and the opening and closing magnet 7 cannot be re-locked within the stirrup frame 1, and it is always in an open state at this time.

[0079] When used again, the rider's foot is placed on the stirrup again, and the side of the foot presses against the hydraulic trigger head 401, triggering the hydraulic trigger member 4, the trigger auxiliary member, the delay member 5, the delay auxiliary member, the locking member 8, and the locking auxiliary member to work again until the reversing magnet 805 reverses again and the return spring returns to its original position. The magnetic pole of the reversing magnet 805 is different from the magnetic pole of the opening and closing magnet 7, and the two magnetic poles attract each other. Under the action of the attracting magnetic force, the chuck 6 presses against the locking contact 803, the locking contact 803 displaces, the locking contact 803 compresses the locking return spring 807, and the displacement of the locking contact 803 drives the side moving rod 8010 and the side moving piston 8011 to move into the side moving tube 809. The hydraulic oil in the side moving tube 809 enters the auxiliary power tube 5022 through the auxiliary hydraulic tube 5027. The hydraulic oil pushes out the auxiliary power slide rod 5023 and the auxiliary power piston 5025 in the auxiliary power tube 5022. The auxiliary power piston 5025 compresses the auxiliary power return spring 5026, and the auxiliary power slide rod 5023 slides within the extension plate 503 until the locking contact 803 enters the locking groove of the chuck 6. Through the reset of the locking return spring 807 and the auxiliary power return spring 5026, the locking contact 803 enters the locking groove of the chuck 6 to lock the chuck 6 and prevent the chuck 6 from detaching from the stirrup frame 1.

[0080] With the cooperation of the delay member 5 and the delay auxiliary member, the hydraulic hose 403 is clamped by the delay cam 507 to reduce the internal area of the pipe, thereby reducing the flow rate of the hydraulic oil in the hydraulic delivery pipe 402, increasing the duration of the liquid flow, and avoiding the rider's foot constantly jolting up and down in the stirrup as the horse runs when the rider's foot is placed in the stirrup. This can easily trigger the hydraulic trigger head 401. Through this extended duration, the trigger switch is avoided from being triggered, resulting in the chuck 6 being disengaged from the stirrup frame 1; the extension plate 503 triggers the opening of the locking member 8 and the locking auxiliary member. Through the auxiliary moving pipe 5022, the auxiliary moving slide rod 5023, the limiting abutting piece 5024, the auxiliary moving piston 5025, and the auxiliary moving return spring 5026, it is controlled that the locking contact 803 is disengaged from the chuck 6. After the locking member 8 and the locking auxiliary member are reset, the chuck 6 re-enters the stirrup frame 1, the locking contact 803 retracts and re-clamps on the chuck 6. The movement of the retraction of the locking contact 803 is under the action of the auxiliary moving pipe 5022, the auxiliary moving slide rod 5023, the limiting abutting piece 5024, the auxiliary moving piston 5025, and the auxiliary moving return spring 5026. The auxiliary moving slide rod 5023 slides on the extension plate 503 and does not affect the delay power cylinder 501 and the power push rod 502, and always remains in the initial state.

[0081] The locking member 8 and the locking auxiliary member reach the reciprocating switching of the magnetic pole direction of the commutation magnet 805 through the hydraulic trigger member 4 and the trigger auxiliary member; when in the open state, the commutation magnet 805 has the same magnetic pole as the opening and closing magnet 7. The same magnetic poles cause the commutation magnet 805 to repel the chuck 6 and the opening and closing magnet 7 out of the stirrup frame 1, and the locking curved plate 3 is in the unlocked state in the stirrup frame 1, facilitating the rider's foot to disengage from the stirrup; in the closed state, the magnetic pole of the commutation magnet 805 is different from the magnetic pole of the opening and closing magnet 7. The two magnetic poles attract each other. Under the attracting magnetic force, the opening and closing magnet 7 causes the chuck 6 to stick to the commutation magnet 805, and the locking contact 803 is stuck in the locking groove of the chuck 6 to prevent the chuck 6 from disengaging from the stirrup frame 1.

[0082] During the riding process, the rider may lose balance due to the horse getting out of control, uneven ground, or other reasons; to avoid injury, the rider's foot needs to quickly disengage from the stirrup at any time. Especially during the process of falling, the rider needs to quickly trigger the opening of the hydraulic trigger head 401 sideways, so that the locking curved plate 3 is unlocked on the stirrup frame 1, and the feet are pedaling on the stirrup frame 1 to prevent the feet from being stuck or injured; when the rider gets rid of the loss of balance, trigger the opening of the hydraulic trigger head 401 sideways again, so that the locking curved plate 3 is locked on the stirrup frame 1.

[0083] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
