Description

Technical Field

[0001] This invention relates to the field of locking devices, and more particularly to a steering locking structure. Background Technology

[0002] In daily life, steering mechanisms are frequently found in adjustable-direction beds, vehicles, and agricultural machinery. When the steering mechanism is unlocked, the equipment can turn; when locked, the equipment's angle is fixed. Existing steering mechanisms typically use a ratchet locking structure for locking. However, after prolonged use, ratchet locking structures experience reduced reliability due to wear, leading to locking failure and preventing the equipment from being fixed at the specified angle. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a steering locking structure that is not easily worn and has high reliability.

[0004] One of the objectives of this invention is achieved through the following technical solution:

[0005] A steering locking structure includes a bracket and a rotating assembly. The rotating assembly includes a rotating shaft rotatably mounted on the bracket. The rotating assembly also includes a locking plate fixedly connected to the rotating shaft, and the locking plate has multiple locking holes. The steering locking structure further includes an operating member, a moving assembly, and a locking assembly. The operating member is movably mounted on the bracket and has a drive groove. The moving assembly is slidably mounted on the bracket and includes a pressing part, an lifting part, and a transmission part. The transmission part is located in the drive groove. The locking assembly is at least partially located between the pressing part and the lifting part, and the locking assembly also includes a locking part. The operating member moves relative to the bracket, causing the moving assembly to slide relative to the bracket. When the moving assembly slides upward relative to the bracket, the lifting part abuts against the locking assembly, causing the locking part to separate from the locking holes, and the rotating shaft unlocks. When the moving assembly slides downward relative to the bracket, the pressing part abuts against the locking assembly, causing the locking part to enter the locking holes, and the rotating shaft locks.

[0006] Furthermore, the plurality of said locking holes are located on the circumference.

[0007] Furthermore, the locking assembly includes two locking pins and a connecting rod connecting the two locking pins, the connecting rod being located between the pressing part and the lifting part.

[0008] Furthermore, the locking pins are arranged vertically, the two locking pins are parallel to each other, the connecting rod is perpendicular to the locking pins, and the locking part is located at the end of the locking pin away from the connecting rod.

[0009] Furthermore, the plurality of locking holes correspond to the positions of the two locking pins respectively, and the plurality of locking holes are symmetrical about the axis of rotation.

[0010] Furthermore, the bracket includes a top plate, a bottom plate, two side plates, and a mounting plate. The two ends of the side plates are fixed to the top plate and the bottom plate, respectively. The mounting plate is installed between the top plate and the bottom plate. The mounting plate is provided with a first sliding groove and a second sliding groove, both of which extend in the same direction. The pressing part is located in the first sliding groove, and the lifting part is located in the second sliding groove. The pressing part and the lifting part are located on one side of the mounting plate, and the transmission part is located on the other side of the mounting plate.

[0011] Furthermore, the side plate is provided with an operating groove, and the operating component extends into the operating groove and is rotatably connected to the mounting plate.

[0012] Furthermore, there are two operating components, which are arranged crosswise, and the transmission part is located in the drive slot of the two operating components.

[0013] Furthermore, the steering locking structure also includes a pressing component, which includes a pressing link and an elastic element. The pressing link is rotatably mounted on the mounting plate and has a snap-fit ​​groove. The elastic element applies a pulling force to the pressing link. When the shaft is unlocked, the pressing part engages with the snap-fit ​​groove to prevent the locking part from entering the locking hole. When the shaft is locked, the pressing link presses against the pressing part to prevent the locking part from disengaging from the locking hole.

[0014] Furthermore, there are two pressure-blocking links, and the two ends of the elastic element are respectively connected to the two pressure-blocking links. The elastic element applies tension to the pressure-blocking links when it is in a compressed state. The pressure-blocking links are provided with inclined surfaces, and the inclined surfaces abut against the pressing part.

[0015] Compared to existing technologies, the locking plate of the steering locking structure of this invention is fixedly connected to the rotating shaft. The locking plate is provided with multiple locking holes. The steering locking structure also includes an operating component, a moving component, and a locking component. The operating component is movably mounted on the bracket and is provided with a drive groove. The moving component is slidably mounted on the bracket and includes a pressing part, an lifting part, and a transmission part. The transmission part is located in the drive groove. The locking component is at least partially located between the pressing part and the lifting part and includes a locking part. The operating component moves relative to the bracket, causing the moving component to slide relative to the bracket. When the moving component slides upward relative to the bracket, the lifting part abuts against the locking component, causing the locking part to separate from the locking hole, and the rotating shaft is unlocked. When the moving component slides downward relative to the bracket, the pressing part abuts against the locking component, causing the locking part to enter the locking hole, and the rotating shaft is locked. Through the above design, the unlocking and locking of the rotating shaft are achieved by the locking part entering and disengaging from the locking hole. The locking part and the locking hole are not easily worn and have high reliability. Attached Figure Description

[0025] Please see Figures 1 to 5 The steering locking structure includes a bracket 10, an operating component 20, a rotating component 30, a pressing component 40, a moving component 50, and a locking component 60.

[0026] The bracket 10 includes a base plate 11, a top plate 12, two side plates 13, and a mounting plate 14. The base plate 11 and the top plate 12 are arranged in parallel. The two side plates 13 are parallel to each other and perpendicular to the base plate 11. The top of each side plate 13 is fixed to the top plate 12, and the bottom of each side plate 13 is fixed to the base plate 11. Specifically, the base plate 11 is provided with a first mounting hole 110 and two limiting blocks 111. The first mounting hole 110 is used to install the rotating shaft 31. The two limiting blocks 111 are located on both sides of the first mounting hole 110 and are used to limit the rotation angle of the locking plate 32, thereby limiting the rotation angle of the rotating shaft 31 and preventing the rotating shaft 31 from rotating too much when it turns. The top plate 12 is provided with a second mounting hole 120, the position of which corresponds to the position of the first mounting hole 110. The second mounting hole 120 is used to install the rotating shaft 31.

[0027] Each side panel 13 is provided with an operation groove 130, which is arranged in a vertical direction. The operation member 20 extends into the operation groove 130. When the operation member 20 rotates relative to the bracket 10, the end of the operation member 20 moves in the operation groove 130.

[0028] Mounting plate 14 is used to mount the pressing component 40, the moving component 50, and the locking component 60. Mounting plate 14 is provided with a clearance groove 140, a first sliding groove 141, and a second sliding groove 142. The clearance groove 140 is used to mount the elastic element 42. Specifically, the clearance groove 140 is horizontally positioned. The first sliding groove 141 is used to mount the pressing part 52 and simultaneously guide the moving component 50. Specifically, the first sliding groove 141 is vertically positioned, and the number of first sliding grooves 141 is the same as the number of pressing parts 52, consisting of two parallel first sliding grooves 141. The second sliding groove 142 is used to mount the lifting part 53 and simultaneously guide the moving component 50. The second sliding groove 142 is located below the first sliding groove 141.

[0029] The operating element 20 is used to drive the moving component 50 to unlock or lock. Specifically, there are two operating elements 20, each including an operating part 21, an extension part 22, and a connecting part 23. The operating part 21, the extension part 22, and the connecting part 23 are integrally formed, with the operating part 21 and the connecting part 23 located at opposite ends of the extension part 22, and the operating part 21 is perpendicular to the extension part 22. The operating part 21 is used by the user for gripping and operation. The extension part 22 is provided with a drive groove 220, which drives the moving component 50 to move up and down. The connecting part 23 is rotatably connected to the mounting plate 14. The two operating elements 20 are arranged crosswise in an X shape.

[0030] The rotating assembly 30 includes a rotating shaft 31 and a locking plate 32 fixedly connected to the rotating shaft 31. The two ends of the rotating shaft 31 are respectively installed in a first mounting hole 110 and a second mounting hole 120, allowing the rotating shaft 31 to be rotatably mounted on the bracket 10. The locking plate 32 is fan-shaped and rotates with the rotating shaft 31. The locking plate 32 has multiple locking holes 320, each locking part 610 corresponding to multiple locking holes 320, enabling the rotating shaft 31 to be locked at different angles and achieve multiple reversals. Specifically, the multiple locking holes 320 are located on a circumference and distributed in two locations. The two locking holes 320 correspond to two locking parts 610, and the two locking holes 320 are symmetrical about the first mounting hole 110.

[0031] The pressing assembly 40 includes two pressing rods 41 and an elastic member 42 connecting the two pressing rods 41. One end of each pressing rod 41 is rotatably connected to the mounting plate 14, and the other end is connected to the elastic member 42. Specifically, each pressing rod 41 is provided with a latching groove 410 and an inclined surface. The latching groove 410 can latch with the pressing part 52, keeping the steering locking structure in an unlocked state. The inclined surface can press against the pressing part 52, preventing the locking part 610 from disengaging from the locking hole 320. The two pressing rods 41 are arranged in a V-shape. The elastic element 42 is a spring and is in a compressed state. The elastic element 42 is horizontally arranged to provide tension to the pressing rods 41, so that the latching groove 410 of the pressing rods 41 can latch the pressing part 52, keeping the steering locking structure in the unlocked state. In addition, the elastic element 42 can also ensure that after the pressing part 52 is unlocked from the latching groove 410, the pressing rods 41 always press against the pressing part 52, preventing the locking part 610 from disengaging from the locking hole 320.

[0032] The moving assembly 50 includes a moving plate 51, a pressing part 52, an lifting part 53, and a transmission part 54. The pressing part 52 and the lifting part 53 are fixed to one side of the moving plate 51, and the transmission part 54 is fixed to the other side of the moving plate 51. Specifically, the pressing part 52 is a bearing, and there are two pressing parts 52, which are located on the same straight line. The pressing part 52 is located in the first slide groove 141, and the lifting part 53 is located below the two pressing parts 52. The transmission part 54 is located in the drive groove 220 of the two operating parts 20. When the operating part 21 rotates, the drive groove 220 drives the transmission part 54 to slide in the vertical direction. At this time, the pressing part 52 slides in the first slide groove 141, and the lifting part 53 slides in the second slide groove 142.

[0033] The locking assembly 60 includes two locking pins 61 and a connecting rod 62 connecting the two locking pins 61. The two locking pins 61 are parallel to each other and arranged vertically. Each locking pin 61 has a locking part 610 at its end, and the locking part 610 is tapered. The two ends of the connecting rod 62 are fixedly connected to the two locking pins 61 respectively, and the connecting rod 62 is arranged horizontally. The connecting rod 62 is located between the two pressing parts 52 and the lifting part 53.

[0034] When assembling the steering locking structure, the two ends of the rotating shaft 31 are respectively installed in the first mounting hole 110 and the second mounting hole 120, so that the rotating shaft 31 is rotatably mounted on the bracket 10, and the locking plate 32 is fixedly connected to the rotating shaft 31. The connecting part 23 of the operating member 20 is rotatably connected to the mounting plate 14. The pressing part 52 of the moving component 50 is located in the first slide groove 141, the lifting part 53 is located in the second slide groove 142, and the transmission part 54 is located in the drive groove 220 of the two operating members 20. One end of each pressing link 41 of the pressing component 40 is rotatably connected to the mounting plate 14, and the other end is connected to the elastic member 42.

[0035] When using the steering lock structure, the user holds the operating part 21 of the operating member 20 and rotates the operating member 20 upwards. The drive groove 220 drives the transmission part 54 to slide vertically. At this time, the pressing part 52 slides in the first slide groove 141, and the lifting part 53 slides in the second slide groove 142. At this time, the lifting part 53 abuts against the connecting rod 62, causing the locking component 60 to move upwards, the locking part 610 to separate from the locking hole 320, and the steering lock structure is unlocked. When the pressing part 52 moves upwards to its limit position, the pressing part 52 engages with the latch groove 410. When the user releases their hand, the moving component 50 stays in its original position, keeping the steering lock structure locked. The rotating shaft 31 rotates. When the rotating shaft 31 is rotated to the specified angle, the user rotates the operating member 20 downwards. The drive groove 220 drives the transmission part 54 to slide downwards in the vertical direction. The pressing part 52 disengages from the buckle groove 410 and moves downwards, contacting the connecting rod 62. The connecting rod 62 moves downwards, and the locking part 610 of the locking pin 61 extends into the locking hole 320, locking the rotating shaft 31 and the bracket 10. At this time, the inclined surface of the pressing connecting rod 41 contacts the pressing part 52, preventing the locking part 610 from disengaging from the locking hole 320.

[0036] With the above design, the unlocking and locking of the rotating shaft 31 are achieved by the locking part 610 entering and disengaging from the locking hole 320. The locking part 610 and the locking hole 320 are not easily worn and have high reliability.

[0037] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
