Description

Technical Field

[0001] The invention relates to the technical field of horse gear products, and in particular to a self-locking safety stirrup. Background Art

[0002] Since its appearance, traditional stirrups have mainly relied on simple mechanical structures to fix the rider's feet. 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 external forces on the feet during riding. Especially when the horse is running at high speed, bumping violently or the rider makes sudden movements, the stirrup head is prone to fall off, causing the rider's foot to accidentally fall off the stirrup.

[0003] The biggest disadvantage of this design is that it cannot effectively prevent the foot from falling off. Especially when the horse is running fast or encountering an unstable road surface, the rider's foot may fall out of the stirrup due to sudden vibration, bumps or falls. If the stirrup does not have a good fixing mechanism, the rider may not only lose control of the horse, but also suffer serious accidents such as falls or collisions. For example, when the horse suddenly turns or the horse accelerates violently, the rider's foot may fall out due to inertia or unstable stirrup design, causing the rider to fall, increasing the risk of major accidents.

[0004] Most existing stirrup designs do not have a self-locking function, which means that riders cannot react or correct their feet in time when they become unstable or fall off during riding, increasing potential safety hazards. Even though 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, causing the stirrup to loosen or lose its fixing effect during frequent riding bumps.

[0005] Traditional stirrups lack a self-locking function and cannot effectively prevent the foot from falling out of the stirrup, which poses a serious threat to the safety of the rider. Therefore, a new stirrup design is urgently needed 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 the foot falling off. Summary of the invention

[0006] The invention provides a self-locking safety stirrup. By changing the magnetic pole direction of a commutation magnet, in an open state, the commutation magnet has the same magnetic pole as the opening and closing magnet, and the same magnetic pole enables the commutation magnet to repel a clamping head and the opening and closing magnet out of a stirrup frame, and a locking curved plate is in an unlocked state in the stirrup frame, so that the rider's foot is convenient to be separated from the stirrup; in a closed state, the magnetic pole of the commutation magnet is different from the magnetic pole of the opening and closing magnet, and the two magnetic poles attract each other. Under the action of the magnetic force of attraction, the opening and closing magnet causes the clamping head to stick to the commutation magnet, and the locking contact is stuck in a locking groove of the clamping head, so that the clamping head is prevented from being separated from the stirrup frame.

The rotation of the second transmission rod 8017 can drive the rotation of the third transmission rod 8020.

[0037] Working principle: When the rider's foot is placed in the stirrup, the foot is lifted sideways to squeeze the hydraulic trigger head 401. When the hydraulic trigger head 401 is squeezed, 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. 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.

[0038] The hydraulic oil in the delay power cylinder 501 is continuously accumulated, pushing the power push rod 502 and the delay piston 509 to move. The power push rod 502 extends outward, and the delay piston 509 compresses the power return spring 5010. The outward movement of the power push rod 502 drives one end of the extension plate 503, and the movement of the extension plate 503 drives the movement of the power plate 504.

[0039] The movement of the power plate 504 drives the movement of the delay gear set 5011 and the delay clamping plate 5012, and 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 shaft 5013 and the incomplete bevel gear 5014. The toothless area of ​​the incomplete bevel gear 5014 contacts the delay bevel gear 5016. At this time, the delay bevel gear 5016 does not rotate until the tooth area of ​​the incomplete bevel gear 5014 meshes with the teeth of the delay bevel gear 5016. The rotation of 14 drives the rotation of the delay bevel gear 5016, and 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 to reduce the area inside the tube, thereby reducing the flow rate of the hydraulic oil in the hydraulic delivery pipe 402 and increasing the duration of liquid flow. The delay gear 5028 disengages from the delay tooth group 5011, and one side of the hexagonal column 5015 is tightly attached to the delay clamping plate 5012, so that the delay cam 507 supports and clamps the hydraulic hose 403.

[0040] The movement of the power plate 504 drives the auxiliary slide bar 5023 and the limit stop plate 5024 to move. The auxiliary slide bar 5023 moves toward the outside of the auxiliary tube 5022. The auxiliary slide bar 5023 drives the auxiliary piston 5025 to move in the auxiliary tube 5022. The auxiliary piston 5025 compresses the auxiliary return spring 5026. The auxiliary piston 5025 generates negative pressure in the auxiliary tube 5022, and the hydraulic oil in the side moving tube 809 is extracted through the auxiliary liquid pipe 5027. The side moving rod 8010 retracts into the side moving tube 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 is disengaged from the clamping head 6, and the movable plate 808 is displaced in the locking movable groove 806.

[0041] The locking contact 803 disengages from the displacement direction of the clamp 6, and the locking contact 803 compresses the locking reset spring 807. The movement of the movable plate 808 drives the reversing plate 8013 to move synchronously. The first reversing gear 8016 drives the rotation of the first reversing gear 8016 when the reversing plate 8013 moves. 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 offset block 8019. The rotation of the first one-way offset block 8019 resists the rotation of the second one-way offset block 8022. The rotation of the second one-way offset block 8022 drives the rotation of the offset rod 8021 and the third transmission rod 8020.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The power return spring 5010 and the auxiliary return spring 5026 are reset, the power push rod 502 is reset in the delay power cylinder 501, and the auxiliary slide rod 5023 is reset in the auxiliary tube 5022; the hydraulic return spring 406 resets the hydraulic piston 405 and the hydraulic trigger head 401, and the hydraulic trigger head 401 extends out of the hydraulic tube 404 and returns to the initial state.

[0046] The commutation magnet 805 and the opening and closing magnet 7 are in a state of repelling each other with the same poles, so that the clamping head 6 and the opening and closing magnet 7 cannot be clamped in the stirrup frame 1 again, and they are always in the open state.

[0047] When using it again, the rider's foot is placed in the stirrup again, and the foot presses the hydraulic trigger head 401 sideways, which triggers the hydraulic trigger component 4, the trigger auxiliary component, the delay component 5, the delay auxiliary component, the locking component 8 and the locking auxiliary component again, until the reversing magnet 805 is reversed again, and the reset spring is reset again, and 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 magnetic force of the opening and closing magnet 7, the clamping head 6 squeezes the locking contact 803, and the locking contact 803 is displaced. The locking contact 803 compresses the locking reset spring 807, and the displacement of the locking contact 803 drives the side moving rod 8010 and The side-moving piston 8011 moves into the side-moving tube 809, and the hydraulic oil in the side-moving tube 809 enters the auxiliary tube 5022 through the auxiliary liquid pipe 5027. The hydraulic oil pushes out the auxiliary slide bar 5023 and the auxiliary piston 5025 in the auxiliary tube 5022. The auxiliary piston 5025 compresses the auxiliary return spring 5026, and the auxiliary slide bar 5023 slides in the extension plate 503 until the locking contact 803 enters the locking groove of the clamping head 6, and is reset by the locking return spring 807 and the auxiliary return spring 5026. The locking contact 803 enters the locking groove of the clamping head 6, locks the clamping head 6, and prevents the clamping head 6 from detaching from the stirrup frame 1.

[0048] With the cooperation of the delay element 5 and the delay auxiliary element, the hydraulic hose 403 is clamped by the delay cam 507 to reduce the area inside the tube, thereby reducing the flow rate of the hydraulic oil in the hydraulic delivery tube 402 and increasing the duration of the liquid flow, so as to prevent the rider's foot from constantly bouncing up and down in the stirrup as the horse runs when the rider's foot is placed in the stirrup, which may easily trigger the hydraulic trigger head 401. Through this extended duration, the switch is avoided from being triggered, causing the clamp head 6 to be separated from the stirrup frame 1; the extension plate 503 triggers the opening of the locking element 8 and the locking auxiliary element, and the auxiliary tube 5022, the auxiliary slide rod 5023, the limit stop plate 5024, the auxiliary slide rod 5025, the limit stop plate 5026, the auxiliary slide rod 5027, the limit stop plate 5028, the limit stop plate 5029, the limit stop plate 5030, the limit stop plate 5031, the limit stop plate 5032, the limit stop plate 5033, the limit stop plate 5034, the limit stop plate 5035, the limit stop plate 5036, the limit stop plate 5037, the limit stop plate 5038, the limit stop plate 5039, the limit stop plate 5040, the limit stop plate 5041, the limit stop plate 5042, the limit stop plate 5043, the limit stop plate 5044, the limit stop plate 5045, the limit stop plate 5046, the limit stop plate 5047, the limit stop plate 5048, the limit stop plate 5049, the limit stop plate 5050, the limit stop plate 5051, the limit stop plate 5052, the limit stop plate 5053, the limit stop plate 5054, the limit stop plate 505 024, the auxiliary piston 5025 and the auxiliary return spring 5026 control the locking contact 803 to disengage from the clamp 6. After the locking part 8 and the locking auxiliary parts are reset, the clamp 6 re-enters the stirrup frame 1, and the locking contact 803 retracts and is re-clamped in the clamp 6. The retraction movement of the locking contact 803 is achieved through the action of the auxiliary tube 5022, the auxiliary slide bar 5023, the limit stop plate 5024, the auxiliary piston 5025 and the auxiliary return spring 5026. The auxiliary slide bar 5023 slides on the extension plate 503, and does not affect the delay power cylinder 501 and the power push rod 502, which are always in the initial state.

[0049] The locking member 8 and the locking auxiliary member switch the magnetic pole direction of the commutation magnet 805 back and forth through the hydraulic trigger member 4 and the trigger auxiliary member; in the open state, the commutation magnet 805 has the same magnetic pole as the opening and closing magnet 7, and the same magnetic pole makes the commutation magnet 805 repel the clamping head 6 and the opening and closing magnet 7 out of the stirrup frame 1, and the locking curved plate 3 is in an unlocked state in the stirrup frame 1, which is convenient for the rider's foot to leave 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, and the two magnetic poles attract each other. Under the action of the magnetic force of the opening and closing magnet 7, the clamping head 6 sticks to the commutation magnet 805, and the locking contact 803 is stuck in the lock groove of the clamping head 6 to prevent the clamping head 6 from leaving the stirrup frame 1.

[0050] During riding, the rider may lose balance due to the horse losing control, uneven ground or other reasons; in order to avoid injury, the rider's feet need to be quickly out of the stirrups at any time, especially in the process of falling, the rider needs to quickly sideways to trigger the hydraulic trigger head 401 to open, so that the locking curved plate 3 is unlocked on the stirrup frame 1, and step on the stirrup frame 1 with both feet to avoid the feet being stuck or injured; when the rider gets rid of the loss of balance, he or she can sideways to trigger the hydraulic trigger head 401 to open, so that the locking curved plate 3 is locked on the stirrup frame 1.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
