[0055] The rotatable, liftable and swingable bicycle vertical line clamping tool will be further described in combination with specific embodiments and drawings.

[0056] Please refer to Figure 1 , Figure 2 The rotatable, liftable and swingable bicycle vertical line clamping tool comprises a telescopic column 1, a rotating seat 2 mounted on the telescopic column 1 and rotatable relative to the telescopic column 1 in a horizontal plane, a rotating arm 3 mounted on the rotating seat 2 and rotatable relative to the rotating seat 2 in a vertical plane, and a swingable clamp mounted on the rotating arm 3. The swingable clamp comprises a clamping unit 4 and a swing control mechanism 9 for controlling the swing angle of the clamping unit 4 and enabling the clamping unit 4 to switch between a first fixed position and a second fixed position. The starting point and the ending point of the swing of the clamping unit 4 correspond to the first fixed position and the second fixed position respectively.

[0057] Of course, the telescopic column 1 is provided with a telescopic control mechanism 5 for adjusting the length of the telescopic column 1. Please refer to Figure 3 The telescopic column 1 comprises an outer tube 11 and an inner tube 12 coaxially arranged, the upper end of the inner tube 12 is arranged in the outer tube 11, and the lower end of the inner tube 12 is arranged outside the outer tube 11. The telescopic control mechanism 5 controls the telescopic column 1 by controlling the up-down movement of the inner tube 12 relative to the outer tube 11. The upper end of the outer tube 11 is connected with a top connector 13, and the lower end of the inner tube 12 is connected with the rotating seat 2.

[0058] In some embodiments of the present application, the telescopic control mechanism 5 comprises a first transmission mechanism and a first driving mechanism. Optionally, the first transmission mechanism is used to convert the rotary motion of the first driving mechanism into the linear motion of the inner tube 12. Please refer to Figure 3 In an exemplary embodiment, the first transmission mechanism comprises a transmission screw 51, a transmission nut 52 and a bevel gear vertical transmission mechanism, and the first driving mechanism comprises a hand wheel 54. The transmission screw 51 is coaxially arranged in the inner tube 12 and cannot move up and down. The transmission nut 52 is threadedly connected with the transmission screw 51 and connected with the inner tube 12. One of the bevel gears of the bevel gear vertical transmission mechanism is mounted on the transmission screw 51, and the other bevel gear is connected with the hand wheel 54. Rotating the hand wheel 54, the rotary motion of the hand wheel 54 is transmitted to the transmission screw 51 through the bevel gear vertical transmission mechanism, and the rotation of the transmission screw 51 drives the transmission nut 52 to move up and down along the transmission screw 51, thereby driving the inner tube 12 to move up and down.

[0059] In the above embodiment, the hand wheel 54 is rotatably connected with the outer tube 11, and there is a bearing between the rotation axis of the hand wheel 54 and the outer tube 11. There is a first avoiding opening 121 on the wall of the inner tube 12, which is used to avoid the bevel gear vertical transmission mechanism and other components, so as to avoid the bevel gear vertical transmission mechanism from blocking the up-down movement of the inner tube 12.

[0060] Optionally, a lower support member 55 is mounted on the outer tube 11, and a bevel gear connected to the transmission screw 51 is mounted on the lower support member 55 with a bearing provided therebetween. The upper end of the transmission screw 51 is rotatably connected to the top connector 13 via a bearing.

[0061] It is described above that the first driving mechanism includes the hand wheel 54, but the present invention is not limited thereto. In other embodiments, the first driving mechanism includes a motor, and the motor is automatically driven.

[0062] The telescopic control mechanism 5 is described above as comprising a drive screw 51, a drive nut 52, a bevel gear vertical transmission mechanism, and a handwheel 54. However, the present invention is not limited thereto. For example, in some embodiments, the telescopic control mechanism 5 does not include a bevel gear vertical transmission mechanism, and the handwheel 54 or motor is directly connected to the drive screw 51. For another example, in some embodiments, the telescopic control mechanism 5 comprises a fastening bolt mounted on the outer tube 11. Length control is achieved by tightening the fastening bolt so that its inner end presses against the inner tube 12, or by screwing the inner end of the fastening bolt into a matching hole in the inner tube 12. This is conventional in the art and will not be further described here.

[0063] The rotating base 2 is equipped with a horizontal rotation locking mechanism 6, which locks the rotating base 2 to prevent it from rotating in the horizontal plane relative to the column 1. Figure 3 、 Figure 4 In an exemplary embodiment, the horizontal rotation locking mechanism 6 includes a gear sleeve 61, a locking block 62, and a first operating mechanism. The locking block 62 has teeth for meshing with the gear sleeve 61. The axis of the gear sleeve 61 is parallel to the vertical plane. The gear sleeve 61 is fixedly connected to the column 1. The locking block 62 is mounted on the rotating base 2 and can move linearly relative to the gear sleeve 61. The locking block 62 has a locked position and an unlocked position. When the locking block 62 is in the locked position, the locking block 62 meshes with the gear sleeve 61. When the locking block 62 is in the unlocked position, the locking block 62 is separated from the gear sleeve 61. The first operating mechanism is used to drive the locking block 62 to perform linear motion relative to the gear sleeve 61, thereby switching the locking block 62 between the locked position and the unlocked position.

[0064] In some embodiments of the present invention, the upper end of the gear sleeve 61 is fixed to the connecting tube 66 by screws, and the connecting tube 66 is fixedly connected to the lower end of the column 1.

[0065] It is worth noting that there are many mechanisms for driving the locking block 62 to achieve linear motion, such as gear racks, screw nuts, cam mechanisms, etc., and those skilled in the art can reasonably set them according to needs. In an exemplary embodiment, Figure 4The first operating mechanism includes an adjusting screw 63 and a rotating handle 64. The rotating seat 2 has a central circular hole matched with the gear sleeve 61. The rotating seat 2 is sleeved outside the gear sleeve 61 and is rotationally connected with the gear sleeve 61. The locking block 62 is arranged in the linear groove 60 of the rotating seat 2, and can only move radially relative to the rotating seat 2 under the constraint of the linear groove 60. The rotating seat 2 has a threaded hole matched with the adjusting screw 63. The adjusting screw 63 is arranged in the threaded hole. One end of the adjusting screw 63 is rotationally connected with the locking block 62, and the other end of the adjusting screw 63 is connected with the rotating handle 64. The rotating handle 64 can drive the adjusting screw 63 to rotate and move radially inward or outward synchronously, thereby driving the locking block 62 to move radially inward or outward, so that the locking block 62 engages or separates from the gear sleeve 61. When the locking block 62 engages with the gear sleeve 61, the locking block 62 and the rotating seat 2 cannot rotate relative to the gear sleeve 61 and the stand 1 in the horizontal plane, thereby achieving locking. When the locking block 62 separates from the gear sleeve 61, the locking block 62 and the rotating seat 2 can rotate relative to the gear sleeve 61 and the stand 1 in the horizontal plane, thereby achieving unlocking.

[0066] Please refer to Figure 3 、 Figure 4 In the exemplary embodiment, the rotating seat 2 includes a bottom support 21, a gland 22 and a vertical rotating shaft 23. The upper part of the vertical rotating shaft 23 is coaxially arranged in the gear sleeve 61 and rotationally matched with the gear sleeve 61 through a bearing. The bottom support 21 is fixedly connected with the flange at the lower end of the vertical rotating shaft 23 through a screw. The gland 22 is located above the bottom support 21 and is fixedly connected with the bottom support 21. The linear groove 60 is located on the gland 22, and the adjusting screw 63 is arranged in the threaded hole of the gland 22. A support ring 65 is coaxially arranged outside the gear sleeve 61 and is fixedly connected with the gear sleeve 61 by a screw, welding or integral manufacturing. The inner wall of the gland 22 has an annular inner step matched with the support ring 65. The annular inner step is supported on the support ring 65, so that the weight of the rotating seat 2 is transmitted to the gear sleeve 61 and then to the stand 1.

[0067] The rotating arm 3 is provided with a vertical rotation locking mechanism 7, by which the rotation angle of the rotating arm 3 in the vertical plane can be controlled. Please refer to Figure 1 、 Figures 5 to 9In the exemplary embodiment, the vertical rotation locking mechanism 7 comprises a brake disc 71 and a locking pin assembly. The brake disc 71 is fixedly connected with the bottom support 21 of the rotating seat 2. The rotating arm 3 is rotatably connected with the rotating shaft 30, and a bearing is arranged between the rotating arm 3 and the rotating shaft 30. The rotating shaft 30 is arranged in the center hole of the brake disc 71, and the brake disc 71 and the rotating shaft 30 are fixed together by bolts or screws. The locking pin assembly is arranged on the brake disc 71. The locking pin assembly comprises a locking pin 72, a locking pin seat 73, and a first handle 74. The locking pin seat 73 and the brake disc 71 each have a pin hole matched with the locking pin 72. The locking pin 72 is arranged in the pin hole of the brake disc 71 and the locking pin seat 73, and can rotate relative to the brake disc 71 and move in a first direction. The first direction is parallel to the axial direction of the rotating shaft 30. A plurality of lock holes 31 are arranged on the rotating arm 3 on the same circumference around the rotating shaft 30. The rotating arm 3 performs a rotating motion, and the plurality of lock holes 31 can be aligned with the locking pin 72 one by one. The locking pin 72 has a locking position and an unlocking position. When the locking pin 72 is in the locking position, the locking pin 72 is inserted into one of the lock holes 31 of the rotating arm 3. When the locking pin 72 is in the unlocking position, the locking pin 72 is separated from the rotating arm 3. The first handle 74 is connected with the locking pin 72, and is used to drive the locking pin 72 to move in the first direction relative to the brake disc 71, so as to switch the locking pin 72 between the locking position and the unlocking position.

[0068] When the locking pin 72 is in the locking position, in order to avoid that the locking pin 72 moves and switches to the unlocking position under unexpected circumstances. Please refer to Figure 6 、 Figure 9 In the exemplary embodiment, the locking pin seat 73 has a strip hole 75 matched with the first handle 74. One end of the first handle 74 extends into the locking pin seat 73 from the strip hole 75 and is connected with the locking pin 72. The strip hole 75 allows the first handle 74 to move in the first direction relative to the locking pin seat 73, and can limit the linear displacement of the locking pin 72. One end of the strip hole 75 has a clamping hole 76. When the locking pin 72 is driven to move to the locking position by the first handle 74, the first handle 74 is located at the clamping hole 76. At this time, rotating the first handle 74 around the locking pin 72 as the rotating center can clamp the handle rod into the clamping hole 76. Since the clamping hole 76 limits the first handle 74, the locking pin 72 can be prevented from being withdrawn from the lock hole 31 of the rotating arm 3, so that the rotating arm 3 remains in the locked state.

[0069] It is worth noting that the locking pin seat 73 and the brake disc 71 can be integrally manufactured, or can be separately manufactured.

[0070] When the locking pin 72 is switched to the unlocking position to adjust the angle of the rotating arm 3, in order to avoid that the rotating arm 3 rotates by itself under the action of its own weight and the gravity of the bicycle, and to increase the stability of angle adjustment. Please refer to Figure 8 、 Figure 9In some embodiments of the present application, a damping device 8 is also installed on the brake disc 71, and the damping device 8 is installed in a mounting cavity on the brake disc 71. The damping device 8 includes a round head spring pin 81, and a plurality of index grooves 32 are arranged on the rotating arm 3 around the rotating shaft 30 on the same circumference and match the round head spring pin 81. The free end of the round head spring pin 81 can be inserted into one of the index grooves 32 under the action of the spring, thereby preventing the rotating arm 3 from rotating in the vertical plane. However, when the rotating external force increases to a certain extent, the round head spring pin 81 can be retracted, thereby rotating the rotating arm 3 in the vertical plane. As a preferred embodiment, the round head spring pin 81 is provided with a spring force adjusting nut 82, and the round head spring pin 81 and the corresponding spring force adjusting nut 82 are installed in the same mounting cavity. The round head spring pin 81 includes a ball head pin and a spring, the spring force adjusting nut 82 is screwed with the brake disc 71, the ball head pin is gap-fitted with the mounting cavity, and the two ends of the spring act on the ball head and the spring force adjusting nut 82, respectively. Under the action of the spring, the free end of the ball head pin protrudes from the brake disc 71. Through the spring force adjusting nut 82, the round head spring pin 81 can be limited on one hand, and the spring force of the round head spring pin 81 can be adjusted on the other hand.

[0071] It is worth noting that the number of index grooves 32 can be reasonably set. Of course, the edges of the index grooves 32 are smoothly transitioned to facilitate the sliding of the free end of the round head spring pin 81 into or out of the index grooves 32.

[0072] In some embodiments, the number of index grooves 32 is equal to and corresponds to the number of lock holes 31. When the round head spring pin 81 is clamped into a certain index groove 32, the locking pin 72 is opposite to one of the lock holes 31. When the angle of the rotating arm 3 in the vertical plane needs to be adjusted, the locking pin 72 is moved backward away from the rotating arm 3 through the first handle 74, and then a slight rotating force is applied to the rotating arm 3 to drive the rotating arm 3 to rotate. With the rotation of the rotating arm 3, the round head spring pin 81 will be clamped into the index grooves 32 one by one, so that the operator will have a jamming feeling during the rotating operation. Therefore, whether the locking pin 72 is opposite to one of the lock holes 31 can be judged by the jamming feeling of the round head spring pin 81 and the index grooves 32. When the rotating arm 3 is rotated to the appropriate angle, the locking pin 72 is moved forward to be inserted into the corresponding lock hole 31 of the rotating arm 3 through the first handle 74, so as to fix the angle of the rotating arm 3 in the vertical plane. As Figure 7 As shown in the figure, in the exemplary embodiment, a lock hole 31 is formed in the bottom of each index groove 32.

[0073] It is worth noting that the number of damping devices 8 can be reasonably set according to needs. As a preferred embodiment, there are at least two damping devices 8. In the exemplary embodiment, there are three damping devices 8.

The swing shaft 40 is perpendicular to the rotating axis of the rotating arm 3. The swing control mechanism 9 controls the swing angle of the clamping unit 4 on the swing frame 10 to be α.

[0075] Please refer to Figures 11 to 14 In the exemplary embodiment, the swing control mechanism 9 comprises a fixed block 91, a movable connecting plate 92, a limiting roller 93 and a spring 94. The fixed block 91 is fixedly connected with or integrally manufactured with the swing frame 10.

[0076] The clamping unit 4 is provided with a fixed connecting plate 95. One end of the movable connecting plate 92 is rotatably connected with the fixed connecting plate 95 through a shaft A 96. The limiting roller 93 is arranged at the other end of the movable connecting plate 92 and is parallel to the swing shaft 40. One end of the spring 94 acts on the fixed block 91, and the other end of the spring 94 acts on the limiting roller 93. The bottom of the fixed block 91 is provided with a contact guide surface 911 for contacting the limiting roller 93. Under the tension of the spring 94, the limiting roller 93 always keeps in contact with the contact guide surface 911 of the fixed block 91 when the clamping unit 4 swings on the swing frame 10.

[0077] The two ends of the contact guide surface 911 are respectively provided with a first limiting groove 912 and a second limiting groove 913 which are adapted to the limiting roller 93. In the initial state, the limiting roller 93 is clamped in the first limiting groove 912. Then the clamping unit 4 is swung, and the limiting roller 93 can move along the contact guide surface 911. When the limiting roller 93 moves to be clamped in the second limiting groove 913, the clamping unit 4 cannot continue to increase the swing angle, thereby realizing the control of the swing angle α.

[0078] It is worth mentioning that the swing angle can be reasonably set according to needs. As a preferred, the swing control mechanism 9 controls the swing angle of the clamping unit 4 on the swing frame 10 to be 30°.

[0079] The control of the swing angle can be realized by changing the positions of the first limiting groove 912 and the second limiting groove 913 and the like.

[0080] In some embodiments, please refer to Figure 13 A hook 941 is rotatably installed on the limiting roller 93 and the fixed block 91. The two ends of the spring 94 are respectively hooked on the hooks 941 of the fixed block 91 and the limiting roller 93. As a preferred, a bearing and a bearing shaft 942 are installed on a round hole 914 of the fixed block 91, and the hook 941 is arranged on the bearing shaft 942.

[0081] To provide more stable and balanced tension for the limiting roller 93, in the exemplary embodiment, there are two springs 94, which are respectively located on both sides of the movable connecting plate 92 and act on both ends of the limiting roller 93.

[0082] In some embodiments, the movable connecting plate 92 is provided with a hook portion 97, and the fixed block 91 is movably provided with a pull ring 98 adapted to the hook portion 97. One end of the pull ring 98 is used to hook the hook portion 97, and the other end of the pull ring 98 is rotatably connected to one end of a second handle 99 through a shaft B981, and the second handle 99 is rotatably connected to the fixed block 91 through a shaft C991. The other end of the second handle 99 can be pulled to operate the pull ring 98 to move. Please refer to Figure 10 , at this time, the clamping unit 4 is in the first fixed position and at the starting point of swinging,

[0083] When the limiting roller 93 of the clamping unit 4 is clamped in the first limiting groove 912, the pull ring 98 is hooked on the hook portion 97, at this time, the clamping unit 4 is pulled by the pull ring 98, so it cannot be rotated. When it is necessary to adjust the swing angle of the clamping unit 4, the other end of the second handle 99 is pulled to move the pull ring 98 in the direction of the hook portion 97, and then the pull ring 98 can be taken off the hook portion 97 to release the constraint on the clamping unit 4; then the clamping unit 4 can be swung, and when the limiting roller 93 moves to be clamped in the second limiting groove 913, the clamping unit 4 reaches the end of the swing stroke and is fixed in the second fixed position, please refer to Figure 12 . Similarly, please refer to Figure 16 , when the limiting roller 93 of the clamping unit 4 is clamped in the second limiting groove 913, the pull ring 98 is hooked on the hook portion 97, at this time, the clamping unit 4 is pulled by the pull ring 98, so it cannot be rotated. When it is necessary to adjust the swing angle of the clamping unit 4, the other end of the second handle 99 is pulled to move the pull ring 98 in the direction of the hook portion 97, and then the pull ring 98 can be taken off the hook portion 97 to release the constraint on the clamping unit 4; then the clamping unit 4 can be swung in the opposite direction, and when the limiting roller 93 moves to be clamped in the second limiting groove 913, the clamping unit 4 returns to and is fixed in the first fixed position.

[0084] In some embodiments, the fixed block 91 includes a mounting fixed plate 915 and a swing guide plate 916, the swing guide plate 916 is perpendicular to the mounting fixed plate 915, the mounting fixed plate 915 is fixedly connected to the swing frame 10, the upper edge of the swing guide plate 916 is connected to the mounting fixed plate 915, and the contact guide surface 911, the first limiting groove 912 and the second limiting groove 913 are located at the lower edge of the swing guide plate 916. As a preferred, the fixed block 91 is integrally manufactured.

[0085] The clamping unit 4 can be an inner expanding clamping tool or an outer clamping tool. In the exemplary embodiment, the clamping unit 4 is an inner expanding clamping tool. The inner expanding clamping tool can have various structures, which can be selected by those skilled in the art as needed.

[0086] Referring to Figure 15 In the exemplary embodiment, the clamping unit 4 includes an expanding body for being inserted into a pipe of a bicycle frame and being fixedly expanded therein, an expanding trigger mechanism for driving the expanding body to switch between an expanding state and a loosening state, and a mounting cylinder 41 for mounting the expanding body and the expanding trigger mechanism. The mounting cylinder 41 has two swing shafts 40 on two sides thereof, one end of the swing bracket 10 has swing shaft holes 101 adapted to the two swing shafts 40, and the swing shafts 40 are mounted in the swing shaft holes 101. Preferably, the two swing shafts 40 are integrally manufactured with the mounting cylinder 41.

[0087] The expanding body includes a tapered sleeve 42 and at least two expanding blocks 43. The lower end of the tapered sleeve 42 has an outer taper, and the inner surface of each expanding block 43 is an inner taper adapted to the outer taper of the tapered sleeve 42. The expanding blocks 43 are arranged on the outer side of the tapered sleeve 42 in the circumferential direction and are in contact with the outer taper of the tapered sleeve 42.

[0088] The expanding trigger mechanism includes a screw rod 44, an adjusting nut 45, and an operating mechanism 46. The adjusting nut 45 is arranged inside the tapered sleeve 42 and coaxial with the tapered sleeve 42. The lower end of the screw rod 44 extends into the tapered sleeve 42 and is threadedly connected with the adjusting nut 45. Each expanding block 43 is movably connected with the adjusting nut 45 through a clamping block 46, and the tapered sleeve 42 has a second avoiding hole 421 for the clamping block 46 to pass through. The adjusting nut 45 can be moved axially in the tapered sleeve 42 by rotating the screw rod 44, thereby driving each expanding block 43 to switch between the position of approaching each other and the position of moving away from each other.

[0089] The screw rod 44 passes through the inner hole of the mounting cylinder 41 and is rotatably connected with the mounting cylinder 41 through a bearing. The upper end of the screw rod 44 is connected with the operating mechanism 46. In the exemplary embodiment, the operating mechanism 46 includes a transmission wheel 51 and a plurality of third handles 462. The third handles 462 are connected with the transmission wheel 51, and the transmission wheel 51 is connected with the screw rod 44.

[0090] A fixed connecting plate 95 is arranged on the tapered sleeve 42. Optionally, a fixed sleeve 47 is coaxially arranged on the outer part of the upper end of the tapered sleeve 42, and the fixed sleeve 47 is connected with the fixed connecting plate 95. Preferably, the fixed sleeve 47 is integrally manufactured with the fixed connecting plate 95, and the fixed sleeve 47 is threadedly connected with the tapered sleeve 42. In some embodiments, the tapered sleeve 42 has a flange 422 on the upper end thereof, and the upper end of the fixed sleeve 47 abuts against the flange 422.

[0091] Referring to Figure 15At this time, the tensioning blocks 43 are close to each other, and the tensioning blocks 43 form an inner hole in the form of a tapered hole as a whole. The diameter of the circumferential surface of the outer surface of each tensioning block 43 is smaller than the inner diameter of the clamped part. At this time, the tensioning body is inserted into the middle tube of the frame; then, the transmission wheel 461 is rotated, and the transmission wheel 461 drives the screw 44 to rotate, and then drives the adjusting nut 45 and the tensioning blocks 43 to move upward. At the same time, the tensioning blocks 43 move radially due to the action of the outer conical surface of the cone sleeve 42 and then separate. In this way, the tensioning blocks 43 can be pressed against the wall of the middle tube of the frame to achieve tension and fixation of the frame.

[0092] Since the inner hole formed as a whole by each tensioning block 43 is a tapered hole, and the tapered section of the tapered sleeve 42 is a corresponding tapered hole, when the tensioning block 43 moves under the action of the tensioning trigger mechanism, it can be pushed to move radially outward, thereby tightening and fixing the frame, and the radial force applied by each tensioning block 43 to the middle tube of the frame is uniform, and the clamping stability is good.

[0093] One of the adjusting nut 45 and the tensioning block 43 has a radial block 46, and the other has a slot 11 adapted for the block 46. One end of the block 46 passes through the second avoidance opening 421 of the tapered sleeve 42 and is installed in the slot 11. In some embodiments, the adjusting nut 45 and the block 46 are manufactured integrally.

[0094] In some embodiments, the present invention is used as follows: Figure 2 、 Figure 3 In the initial state, the rotating arm 3 is not rotating and the clamping unit 4 is not oscillating. At this time, the screw 44 of the clamping unit 4 is parallel to the column, and the swing axis 40 is parallel to the horizontal plane and perpendicular to the rotation axis of the rotating arm 3 and the rotation axis of the rotating base 2. First, the column 1 is fixed to other equipment via the top connector 13. The handwheel 54 is turned to extend the column 1, thereby lowering the clamping unit 4 to facilitate clamping the bicycle frame with the clamping unit. The handwheel 54 is then rotated in the opposite direction to retract the column 1 and raise the bicycle frame to the desired height. The operator can then turn the rotating handle 64 to unlock the locking block 62 and rotate the rotating base 2 to adjust the bicycle frame to any desired position. Please refer to the manual for details. Figure 16 By vertically rotating the locking mechanism 7, the bicycle frame can also be rotated to any angle in the vertical plane; moreover, the operator can also fix the bicycle frame after swinging it with the swing shaft 40 as the fulcrum to avoid line of sight obstruction and cooperate with the operating posture, thereby facilitating the installation of various parts, greatly improving the convenience of operation, and helping to improve assembly efficiency.

[0095] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application.
