[0028] The base 1 is used to be placed on the ground, and the bottom of the main column 2 is connected to the base 1; the sliding sleeve 3 is sleeved on the main column 2 and can move in the vertical direction and rotate in the horizontal plane relative to the main column 2. A bearing 45 is provided between the sliding sleeve 3 and the main column 2 to ensure the smooth movement of the sliding sleeve 3 through the optimal gap. The sliding sleeve locking mechanism 4 is used to lock the height of the sliding sleeve 3 so that it remains relatively still with the main column 2 in the axial direction.

[0029] The rotating arm 5 is mounted on the sliding sleeve 3 and can rotate relative to the sliding sleeve 3 in a vertical plane. The rotating arm locking mechanism 6 is used to lock the rotating arm 5 so that it is fixed at a certain angle. The clamping unit 7 is mounted on the rotating arm 5 and is used to clamp the bicycle frame.

[0030] The balancing elastic device 9 is installed on the main column 2 and is located above the sliding sleeve 3. The balancing elastic device 9 includes a steel wire rope 91, a pulley, a housing and a steel wire rope locking device, etc. This is a conventional technology in this field and will not be repeated here. The lower end of the steel wire rope 91 of the balancing elastic device 9 is connected to the sliding sleeve 3, and can be used to balance the gravity of the sliding sleeve 3, the clamping unit 7 and the clamped bicycle, so as to adjust the height of the bicycle, reduce the labor burden of the workers, and improve the safety performance. Of course, the balancing elastic device 9 can also be equivalent to the main column 2 rotating in the horizontal plane to adapt to the position of the sliding sleeve 3 in the horizontal circumferential direction. Preferably, there is a bearing between the balancing elastic device 9 and the main column 2 to facilitate the rotation of the balancing elastic device 9.

[0031] In some embodiments, such as 1, Figure 4 and Figure 5 As shown, the sleeve locking mechanism 4 includes a clamping body and a first operating mechanism 44, and the first operating mechanism 44 is used to drive the clamping body to switch between the clamping state and the loosening state. Specifically, the clamping body includes an elastic sleeve 41, an inner clamping assembly 42 and a locking throat clamp 43, and the elastic sleeve 41 includes a first barrel section 411 for sleeved on the sleeve 3 and a second barrel section 412 for sleeved outside the main column 2, the diameter of the first barrel section 411 is greater than the diameter of the second barrel section 412, the lower end of the sleeve 3 is located in the first barrel section 411, and the inner clamping assembly 42 is placed in the second barrel section 412 and is located between the inner wall of the second barrel section 412 and the outer wall of the main column 2.

[0032] The inner clamping assembly 42 includes at least three clamping blocks 421, the inner surface of the clamping block 421 is a cylindrical surface matching the outer surface of the main column 2, and the outer surface of the clamping block 421 is a cylindrical surface matching the inner surface of the second barrel section 412. The clamping blocks 421 are arranged on the outer side of the main column 2 along the circumferential direction, and at least three slits 413 are provided on the second barrel section 412 along the circumferential direction. The at least three slits 413 divide the second barrel section 412 into at least three tile-shaped blocks 414, and the number of the tile-shaped blocks 414 is consistent with the number of the clamping blocks 421, and the clamping blocks 421 correspond to the tile-shaped blocks 414 one by one.

[0033] Preferably, the clamping block 421 is fixed to one of the tile-shaped blocks 414 by screws.

[0034] It is worth noting that the number of the clamping blocks 421 is reasonably set according to the needs. In the exemplary embodiment, there are four clamping blocks 421 and four corresponding gaps 413 .

[0035] The locking throat hoop 43 is sleeved outside the second barrel section 412, and the first operating mechanism 44 is used to drive the locking throat hoop 43 to switch between locking and unlocking. When the locking throat hoop 43 is locked, the elastic jacket 41 shrinks and deforms inwards so that the inner surface of the clamping block 421 is closely fitted with the main column 2 to achieve fixation, preventing the sliding sleeve 3 from sliding down, and achieving the fixing of the sliding sleeve 3 at a certain height; when the locking throat hoop 43 is unlocked, the elastic jacket 41 recovers and deforms outwards under its own elastic force so that the inner surface of the clamping block 421 is separated from the main column 2, and the height of the sliding sleeve 3 can be adjusted up and down at this time.

[0036] Optionally, the upper end of the slit 413 extends to the middle of the first barrel section 411 .

[0037] In some embodiments of the present invention, Figure 6 , Figure 7 As shown, the locking throat hoop 43 includes a throat hoop body and a locking rod 432, one end of the throat hoop body has a first connecting portion 433, the other end of the throat hoop body has a second connecting portion 434, one end of the locking rod 432 is connected to the first connecting portion 433, the other end of the locking rod 432 passes through the through hole on the second connecting portion 434 and is connected to the first operating mechanism 44, the first operating mechanism 44 can be used to adjust the gap between the first connecting portion 433 and the second connecting portion 434, thereby realizing the locking and unlocking of the locking throat hoop 43.

[0038] Optionally, the locking throat clamp 43 also includes a locking block 435, which is located between the first connecting part 433 and the second connecting part 434 and is close to the second connecting part 434, the locking rod 432 passes through the through hole on the locking block 435, and the locking block 435 is fixed to the elastic sleeve 41 through the screw hole 436.

[0039] In some embodiments of the present invention, the first operating mechanism 44 includes a first gap adjustment block 441 and a first operating rod 442. The first gap adjustment block 441 is rotatably connected to one end of the locking rod 432 through an axis A443. The axis A443 is perpendicular to the axis of the locking rod 432. A first push pin 444 is fixedly mounted on the second connecting portion 434. A first gap adjustment surface 445 matching the first push pin 444 is disposed on the first gap adjustment block 441. The first operating rod 442 is connected to the first gap adjustment block 441 and is used to operate the first gap adjustment block 441 to rotate around the axis A443. As the contact position of the first push pin 444 and the first gap adjustment surface 445 changes, the gap between the first gap adjustment block 441 and the second connecting portion 434 also changes accordingly. Then, the gap between the first connecting portion 433 and the second connecting portion 434 is driven to change through the locking rod 432, thereby realizing the locking and unlocking of the throat clamp body.

[0040] Optional, such as Figure 8 As shown, a first positioning groove 446 matching with the first ejector pin 444 is provided on the first clearance adjustment surface 445 of the first clearance adjustment block 441, and the end of the first ejector pin 444 can be sunk into the first positioning groove 446 to achieve clearance locking. Generally speaking, when the locking throat hoop 43 is locked, the end of the first ejector pin 444 falls into the first positioning groove 446. Preferably, the first ejector pin 444 is a ball pin, and the first positioning groove 446 is a spherical groove matching with the ball pin.

[0041] It is worth noting that the first gap adjustment surface 445 may be an inclined surface, a curved surface, etc. Optionally, the first gap adjustment block 441 is a cam, and the first positioning groove 446 is located at the vertex of the cam.

[0042] The first operating mechanism 44 described above includes a first gap adjustment block 441 and a first operating rod 442. However, the present invention is not limited thereto. Specifically, in some embodiments, the first operating mechanism 44 includes an adjusting nut, which is threadedly connected to the locking rod 432. Rotating the adjusting nut can drive the rod to move axially and then tighten or loosen the locking throat clamp 43. This is a conventional technology in the art and will not be described in detail here.

[0043] The above description shows that the sleeve locking mechanism 4 includes a clamping body and a first operating mechanism 44. However, the present invention is not limited thereto. In other embodiments, the sleeve locking mechanism 4 includes a locking bolt disposed on the sleeve 3, and the corresponding main column 2 is provided with a plurality of bolt holes or positioning grooves adapted to the locking bolt. The sleeve 3 is fixed by tightening the bolt, inserting it into a bolt hole or withdrawing it. This is a conventional technology in the art and will not be described in detail here.

[0044] In some embodiments, Figure 4As shown, the rotating arm 5 is rotatably connected to the sliding sleeve 3 via a horizontal shaft 51 , and the rotating arm locking mechanism 6 fixes the angle of the rotating arm 5 by locking the horizontal shaft 51 .

[0045] In some embodiments, Fig. 9 , Fig.10 As shown, the rotating arm locking mechanism 6 includes a seat body 60, a locking device and a second operating mechanism. The seat body 60 is fixed to the sliding sleeve 3 by screws or bolts or other means. The locking device includes a locking gear 61 and a gear locking block 62 used to cooperate with the locking gear 61. The locking gear 61 is installed on the horizontal shaft 51. The gear locking block 62 is installed on the seat body 60 and can move linearly relative to the locking gear 61. The gear locking block 62 has a locking position and an unlocking position. When the gear locking block 62 is in the locking position, the gear locking block 62 is meshed with the locking gear 61. When the gear locking block 62 is in the unlocking position, the gear locking block 62 is separated from the locking gear 61.

[0046] The second operating mechanism is used to drive the gear lock block 62 to perform linear motion relative to the locking gear 61, thereby switching the locking gear 61 between the locking position and the unlocking position. It is worth noting that there are many linear motion drive mechanisms, such as gear racks, screw nuts, etc., and those skilled in the art can reasonably set them according to needs.

[0047] In some embodiments of the present invention, Fig.10 As shown, the second operating mechanism includes a second gap adjustment block 63, a second operating rod 64 and a spring 65. The second gap adjustment block 63 is rotatably connected to the seat body 60 through an axis B66. The axis B66 is perpendicular to the axis of the locking gear 61. The gear locking block 62 is provided with a second push pin 66. The second gap adjustment block 63 has a second gap adjustment surface 631 adapted to the second push pin 66. The spring 65 acts on the gear locking block 62. Under the action of the spring 65, the end of the second push pin 66 abuts against the second gap adjustment surface 631 of the second gap adjustment block 63. The second operating rod 64 is connected to the second gap adjustment block 63 and is used to operate the second gap adjustment block 63 to rotate around the axis B66. As the contact position of the second push pin 66 and the second gap adjustment surface 631 changes, the gear locking block 62 also moves accordingly, and the gap between the locking gear 61 and the gear locking block 62 also changes accordingly, thereby achieving locking and unlocking.

[0048] Optional, such as Fig.11As shown, there is a second positioning groove 632 adapted to the second ejector pin 66 on the second gap adjustment surface 631 of the second gap adjustment block 63, and the end of the second ejector pin 66 can fall into the second positioning groove 632 to achieve gap locking. In an exemplary embodiment, as shown in the figure, when the gear lock block 62 is in the locking position, the end of the second ejector pin 66 falls into the second positioning groove 632; at this time, the second gap adjustment block 63 is rotated, and the end of the second ejector pin 66 withdraws from the second positioning groove 632 and moves to the right under the pulling force of the spring 65 and synchronously drives the gear lock block 62 to move to the right, and finally the gear lock block 62 moves to the unlocking position, realizing the separation of the gear lock block 62 and the locking gear 61.

[0049] Preferably, the second ejector pin 66 is a ball pin, and the second positioning groove 632 is a spherical groove matching the ball pin.

[0050] It is worth noting that the second gap adjustment surface 631 may be an inclined surface, a curved surface, etc. Optionally, the second gap adjustment block 63 is a cam, and the second positioning groove 632 is located at the vertex of the cam.

[0051] In some embodiments, Fig.10 As shown, a telescopic rod 68 is installed on the seat body 60, the other end of the telescopic rod 68 is connected to the gear lock block 62, and the spring 65 is sleeved on the telescopic rod 68. Preferably, a telescopic rod adjustment nut 69 is installed on the seat body 60, the telescopic rod adjustment nut 69 is threadedly connected to the seat body 60, one end of the telescopic rod 68 is installed in the hole in the telescopic rod adjustment nut 69, and the two ends of the spring 65 act on the gear lock block 62 and the telescopic rod adjustment nut 69 respectively. In order to further increase the stability of the movement of the gear lock block 62, there are two telescopic rods 68, and the two telescopic rods 68 are symmetrically arranged on both sides of the second top pin 66; correspondingly, there are two springs 65.

[0052] When the gear lock block 62 is switched to the unlocked position for adjusting the angle, the rotation arm 5 is prevented from rotating automatically under the gravity of the bicycle, thereby increasing the stability of the angle adjustment. In some embodiments of the present invention, a damping device 8 is further provided, such as Figure 4 , Fig. 9 and Fig.12 As shown, the damping device 8 includes a dividing sleeve 81 and a round spring pin 82. The dividing sleeve 81 is sleeved on the horizontal shaft 51 and can rotate with the horizontal shaft 51. A plurality of dividing grooves 83 matching the round spring pin 82 are arranged along the circumferential direction on the outer circumferential surface of the dividing sleeve 81. The free end of the round spring pin 82 is stuck in one of the dividing grooves 83 under the action of its own elastic force, thereby preventing the dividing sleeve 81, the horizontal shaft 51 and the rotating arm 5 from rotating in the vertical plane. However, when the external rotational force increases to a certain extent, the round spring pin 82 can be forced to retract, thereby rotating the rotating arm 5 in the vertical plane.

[0053] It is worth noting that the number of indexing grooves 83 can be set reasonably. Of course, the indexing grooves 83 and the outer cylindrical surface of the indexing sleeve 81 have a smooth transition so that the free end of the round spring pin 82 can slide in or out of the indexing groove 83.

[0054] Of course, the damping device 8 also includes a cover 84, which covers the indexing sleeve 81 and is fixed to the sliding sleeve 3 by screws or other means. The round spring pin 82 is installed in the cover 84; preferably, the cover 84 is equipped with an elastic force adjustment nut 85, through which the elastic force of the round spring pin 82 can be adjusted.

[0055] Preferably, a wire rope bracket shaft 86 is provided at the top of the cover shell 84 , and one end of the wire rope 91 of the balancing elastic device 9 is connected to the wire rope bracket shaft 86 .

[0056] In some embodiments of the present invention, Figure 4 , Figure 5 As shown, the sleeve 3 includes a vertical cylinder 31 and a horizontal cylinder 32. The vertical cylinder 31 is sleeved outside the main column 2, and the horizontal shaft 51 is placed in the horizontal cylinder 32 and is rotatably connected to the horizontal cylinder 32 through a bearing. The rotating arm 5 is fixedly connected through the horizontal shaft 51. As a preference, the vertical cylinder 31 and the horizontal cylinder 32 are manufactured in one piece. Fig. 9 As shown, the seat body 60 is fixed to the sliding sleeve 3 by screws or bolts or other means; the cover shell 84 is fixed to the horizontal cylinder 32 by screws or other means.

[0057] Wherein, the clamping unit 7 can be an inner tensioning clamping tool or an outer clamping clamping tool. Preferably, the clamping unit 7 is detachably connected to the rotating arm 5, so that different clamping tools can be replaced according to different vehicle models to meet the needs of different vehicle models.

[0058] In some embodiments of the present invention, Fig.13 As shown, the clamping unit includes a first clamping arm 71, a second clamping arm 72, an elastic mechanism and a locking mechanism 74. The first clamping arm 71 is rotatably connected to the second clamping arm 72 via a shaft 75, and one end of both clamping arms has a clamping portion 70; the clamping portion 70 of the first clamping arm 71 is arranged opposite to the clamping portion 70 of the second clamping arm 72.

[0059] The elastic mechanism acts on the first clamping arm 71 and the second clamping arm 72 . Under the action of the elastic mechanism, the clamping portion 70 of the first clamping arm 71 and the clamping portion 70 of the second clamping arm 72 tend to separate.

[0060] The locking mechanism 74 is used to drive the clamping portion 70 of the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 to approach and clamp and maintain them in the clamped state and to achieve unlocking. Fig.14As shown, the locking mechanism 74 includes a pull rod 741, an abutment block 742, and a cam 743 and a wheel axle 744. One end of the pull rod 741 is connected to the first clamping arm 71, and the other end of the pull rod 741 has an opening with a wheel axle 744. The axial direction of the wheel axle 744 is perpendicular to the axial direction of the pull rod 741. The cam 743 is mounted on the wheel axle 744 and can rotate around the wheel axle 744.

[0061] The second clamp arm 72 and the abutting block 742 are both provided with a pull rod hole adapted to the pull rod 741 , and the pull rod 741 is installed in the pull rod holes of the second clamp arm 72 and the abutting block 742 .

[0062] The abutment block 742 includes a first abutment portion for abutting against the second clamping arm 72 and a second abutment portion for abutting against the cam 743 and matching with the wheel surface of the cam 743. Under the action of the elastic mechanism, the second clamping arm 72 can push the abutment block 742 to make the second abutment portion of the abutment block 742 abut against the cam 743, and the rotation of the cam 743 can make the abutment block 742 slide in a straight line along the pull rod 741 in both directions, thereby switching the clamping portion 70 of the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 between clamping locking and unlocking; after unlocking, the clamping portion 70 of the second clamping arm 72 and the first clamping arm 71 can be ejected under the action of the elastic mechanism; at the same time, due to the existence of the abutment block 742 and the cam 743, the ejection distance can be controlled, so that the spacing distance between the clamping portion 70 of the first clamping arm 71 and the clamping portion 70 of the second clamping arm 72 changes within a suitable range. To facilitate the rotation of the cam 743 , a handle 745 is connected to the cam 743 .

[0063] like Fig.14 As shown, at this time, the abutment block 742 is farthest from the rotation point of the cam 743, and the first clamping arm 71 and the second clamping arm 72 are in a clamped state; when the cam 743 is rotated counterclockwise or clockwise by operating the handle 745, the cam 743 and the second clamping arm 72 move to the left under the elastic force of the elastic mechanism, and the distance between the second clamping arm 72 and the first clamping arm 71 becomes larger, thereby releasing the clamped part.

[0064] To further improve stability, Fig.14 , Fig.15 As shown, a groove 721 for accommodating the abutment block 742 is provided on one side of the second clamping arm 72 relative to the first clamping arm 71. The first abutment portion of the abutment block 742 is inserted into the groove 721 and matches the shape of the groove 721. Preferably, the contact surface between the first abutment portion and the groove 721 is a spherical surface, which can reduce friction, while making the force more uniform and the flexibility higher.

[0065] In an exemplary embodiment, the elastic mechanism includes a tension spring 73 , two ends of which are respectively mounted on the first clamp arm 71 and the second clamp arm 72 , and the elastic mechanism always maintains a tension state.

[0066] It is worth noting that, during the switching process between the clamping state and the loosening state, the second clamping arm 72 will rotate around the shaft 75 within a certain angle range, so the pull rod hole on the second clamping arm 72 is a round bar hole.

[0067] In an exemplary embodiment, the other end of the pull rod 741 is a flat portion 7411, and the two cams 743 sandwich the flat portion 7411, and the plane of the flat portion 7411 contacts the end surface of the cam 743. One end of the handle 745 is connected to the two cams 743. Preferably, the handle 745 and the cam 743 are manufactured in one piece.

[0068] The elastic mechanism described above includes a tension spring 73. However, the present invention is not limited thereto. Specifically, in some embodiments, the elastic mechanism is a torsion spring, which can be sleeved on the shaft 75. In other embodiments, the elastic mechanism is a compression spring, which is compressed between the second clamping arm 72 and the first clamping arm 71, so that the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 tend to separate. This is a conventional technology in the art and will not be described in detail here.

[0069] like Fig. 9 As shown, a plurality of connection holes 711 are provided at one end of the first clamping arm 71 away from the clamping portion 70. The end of the first clamping arm 71 away from the clamping portion 70 is bolted to the rotating arm 5 through the plurality of connection holes 711. The clamping unit can be conveniently removed when necessary, and other types of clamping units can be replaced.

[0070] In some embodiments, the clamping parts 70 of the first clamping arm 71 and the second clamping arm 72 can be detachably mounted with nylon clamping blocks 76, which are used to directly contact the clamped part, not only to avoid damaging the paint on the surface of the bicycle frame, but also to replace different nylon clamping blocks 76 according to the size and shape of different frames.

[0071] Since the bicycle whole vehicle assembly single-line machine of this embodiment is directly placed on the ground through its base 1, and the floors of most production workshops are painted, in order to avoid using screws to fix the base 1, in a preferred embodiment, the base 1 includes a chassis 11, and the chassis 11 has a flat bottom surface. The bottom of the main column 2 is connected to the chassis 11, and the chassis 11 is in contact with the ground over a large area to increase the friction between them, and the position can be fixed by the deadweight of the equipment. Fig.16 , Fig.17 shown.

[0072] In addition, since the equipment is heavy, in order to facilitate the movement of the bicycle assembly line machine, in some embodiments, the base 1 further includes a lifting and moving mechanism and a lifting and adjusting mechanism, the lifting and moving mechanism includes a pressing plate 12 and at least three universal wheels 13, the universal wheels 13 are mounted on the pressing plate 12, and the chassis 11 has a avoidance hole 111 corresponding to each universal wheel 13 for the universal wheel 13 to pass through. Of course, the heights of all universal wheels 13 are the same.

[0073] The lifting and adjusting mechanism is used to adjust the height of the pressure plate 12, and can drive the pressure plate 12 to switch between the first position and the second position. When the pressure plate 12 is in the first position, the bottom of the universal wheel 13 is higher than the bottom surface of the chassis 11. When the pressure plate 12 is in the second position, the bottom of the universal wheel 13 is lower than the bottom surface of the chassis 11.

[0074] In the initial state, the pressure plate 12 is located at the first position, at which time the bottom surface of the chassis 11 is in contact with the ground, and the bottom of the universal wheel 13 is higher than the bottom surface of the chassis 11, and thus does not contact the ground, and the mobile lifting universal mechanism is fixed on the ground in a stable manner. Then, the pressure plate 12 can be driven downward to the second position through the lifting adjustment mechanism, and the pressure plate 12 simultaneously drives the universal wheel 13 to move downward from the corresponding avoidance hole 111 on the chassis 11, so that the bottom of each universal wheel 13 is lower than the bottom surface of the chassis 11. At this time, the universal wheel 13 contacts the ground instead of the chassis 11, and the chassis 11 is lifted off the ground under the driving force of the reaction force, and the friction between the chassis 11 and the ground is released. At the same time, multiple universal wheels 13 contact the ground, and at this time, the entire mechanism and the equipment body on the mechanism can be moved very easily. When the mobile lifting universal mechanism and the equipment body installed thereon are moved to the predetermined position by the universal wheel 13, the pressure plate 12 is driven to move upward by the lifting adjustment mechanism, thereby driving the universal wheel 13 to be lifted upward to leave the ground. At the same time, the chassis 11 contacts the ground again under the reaction force, thereby fixing the equipment in the new position.

[0075] It is worth noting that the lifting and lowering adjustment mechanism can be a manual lifting and lowering adjustment mechanism or an automatic lifting and lowering adjustment mechanism. In an exemplary embodiment, the lifting and lowering adjustment mechanism is a manual adjustment structure. Specifically, Fig.16 , Fig.17 As shown, the lifting and lowering adjustment mechanism includes an adjusting sleeve 14, an adjusting nut 15 and a main spring 16. The bottom end of the adjusting sleeve 14 is connected to the chassis 11. The outer surface of the adjusting sleeve 14 has an external thread matching the adjusting nut 15. The adjusting nut 15 is threadedly connected to the adjusting sleeve 14. The adjusting sleeve 14 passes through the hole on the pressing plate 12, and the pressing plate 12 can move up and down along the adjusting sleeve 14. The main spring 16 is installed between the pressing plate 12 and the chassis 11. Under the action of the main spring 16, the pressing plate 12 tends to move upward away from the chassis 11. The adjusting nut 15 is located above the pressing plate 12. The adjusting nut 15 is screwed downward to move it downward. The pressing plate 12 is subjected to the downward pressure of the adjusting nut 15 and overcomes the elastic force of the main spring 16 and then moves downward, and drives the universal wheel 13 to move downward from the corresponding avoidance hole 111 of the chassis 11 to the bottom of the wheel below the bottom surface of the chassis 11. At this time, the universal wheel 13 replaces the chassis 11 to contact the ground; similarly, the adjusting nut 15 is screwed upward, and the adjusting nut 15 moves upward. Under the action of the main spring 16, the pressing plate 12 is lifted upward to leave the ground, and the chassis 11 is also driven by the reaction force to contact the ground again. In order to facilitate the screwing of the adjusting nut 15, a lever hole is provided on the adjusting nut 15.

[0076] The lifting and lowering adjustment mechanism described above is a manual adjustment mechanism. However, the present invention is not limited thereto. Specifically, in other embodiments, the lifting and lowering adjustment mechanism is an automatic lifting and lowering adjustment mechanism installed on the adjustment sleeve 14, and the automatic lifting and lowering adjustment mechanism can drive the pressing plate 12 to move up and down. The automatic lifting and lowering adjustment mechanism can be an electric lifting and lowering adjustment mechanism, a hydraulic lifting and lowering adjustment mechanism, or a pneumatic lifting and lowering adjustment mechanism. The electric lifting and lowering adjustment mechanism can be an electric push rod, the hydraulic lifting and lowering adjustment mechanism can be a hydraulic cylinder, and the pneumatic lifting and lowering adjustment mechanism can be a cylinder.

[0077] In order to make the base 1 more stable, the adjusting sleeve 14 is connected to the center of the chassis 11, and the adjusting sleeve 14 passes through the center hole of the pressing plate 12 and is in clearance with it, and the universal wheels 13 are evenly arranged on the same circumference around the center hole of the pressing plate 12. The lower end of the main column 2 is installed in the adjusting sleeve 14.

[0078] In order to further improve the stability of the pressing plate 12 during the up and down movement, a plurality of support rods 17 are installed on the chassis 11. The pressing plate 12 has support rod through holes corresponding to the support rods 17. The lower ends of the support rods 17 are connected to the chassis 11, and the upper ends of the support rods 17 are installed in the support rod through holes at the corresponding positions of the pressing plate 12 and are in clearance fit with them. The plurality of support rods 17 have a certain guiding effect on the pressing plate 12, and can prevent the pressing plate 12 from rotating relative to the adjusting sleeve 14, ensuring that the universal wheel 13 is always located directly above the corresponding avoidance hole 111 on the chassis 11.

[0079] It is worth noting that the main spring 16 can be sleeved on the adjustment sleeve 14, and several main springs 16 can be evenly arranged around the adjustment sleeve 14. In the exemplary embodiment, there is one main spring 16 and it is sleeved on the adjustment sleeve 14; several auxiliary springs 18 are provided between the pressure plate 12 and the chassis 11, and the several auxiliary springs 18 are evenly arranged on the same circumference around the main spring 16. Preferably, the number of auxiliary springs 18 is consistent with the number of support rods 17, and the auxiliary springs 18 are sleeved outside the support rods 17 one by one. The upper end of the auxiliary spring 18 is connected to the pressure plate 12, and the lower end of the auxiliary spring 18 is a free end or connected to the chassis 11. When the pressure plate 12 moves downward to be close to the chassis 11, the auxiliary spring 18 can play a certain buffering and vibration reduction effect.

[0080] It is worth noting that the number of universal wheels 13 is reasonably set according to needs, and setting three can basically meet the needs of smooth movement. In an exemplary embodiment, there are four universal wheels 13 and four corresponding avoidance holes 111. As a priority, there are also four support rods 17.

[0081] The shapes of the chassis 11 and the avoidance hole 111 are reasonably set according to needs; preferably, the chassis 11 is a circular disk, and the avoidance hole 111 is a circular hole.

[0082] In order to prevent the operator's feet from touching the universal wheels 13 during operation, in some embodiments of the present invention, the universal wheels 13 are foldable. Specifically, the universal wheel 13 is installed on a flippable wheel frame 131, and the wheel frame 131 is rotatably connected to the pressure plate 12 through a horizontally arranged axis C132. By flipping the universal wheel 13 upward with the axis C132 as the rotation center, the universal wheel 13 can be folded up; at the same time, when the pressure plate 12 is moved downward to the second position, in order to prevent the universal wheel 13 from folding during walking, a wheel frame pressure plate 133 is also provided on the pressure plate 12 for each universal wheel 13, and the wheel frame pressure plate 133 is used to block the wheel frame 131 and prevent it from flipping upward. One end of the wheel frame pressure plate 133 is rotatably connected to the pressure plate 12 through a vertical axis, and the wheel frame pressure plate 133 can be rotated to switch it between the first position and the second position; when the wheel frame pressure plate 133 is in the first position, the wheel frame pressure plate 133 can block above the wheel frame 131 to prevent the wheel frame 131 from flipping upward, please refer to Fig.16 , at this time, the wheel frame pressure plate 133 is located in the first position; when the wheel frame pressure plate 133 is located in the second position, the wheel frame pressure plate 133 is staggered with the wheel frame 131, and the wheel frame 131 can be flipped upward.

[0083] like Fig.18As shown, in an exemplary embodiment, the frame of the bicycle 10 is fixed on the bicycle whole vehicle assembly single-line machine by the clamping unit 7, so that the sliding sleeve locking mechanism 4 is unlocked. Due to the action of the balancing elastic device 9, the bicycle 10 will not fall rapidly under the action of its own weight. The operator can adjust the height of the bicycle 10 according to his own height with a little manpower, and then lock the sliding sleeve locking mechanism 4 to fix the bicycle 10 at a suitable height, and then assemble parts on the bicycle frame; during the assembly process, the operator can rotate the bicycle frame in the horizontal plane according to his own position and operation requirements, and can also adjust the angle of the bicycle frame in the vertical plane through the rotating arm 5 and the rotating arm locking mechanism 6; when the assembly is completed, the sliding sleeve locking mechanism 4 is unlocked, and the operator can lower the assembled bicycle 10 to the ground with a little manpower to complete the unloading, which can provide maximum convenience for the assembly work.

[0084] Moreover, when it is necessary to assemble the bicycle at another position, the universal wheel 13 can be lowered by the lifting and adjusting mechanism, and then the equipment and the bicycle to be assembled can be easily moved; then the universal wheel 13 is raised again, and the chassis contacts the ground again, and the position is fixed by using reliable equipment and the deadweight of the bicycle to be assembled, which saves time and effort and is easy to operate; moreover, it is not easy to slip between the chassis and the ground, and the stability is good and the use is safe.

[0085] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
