A preferred embodiment includes a fixed sleeve 10, a movable sleeve 20, a limit member 30, and a seat adapter 40.

As shown in FIG. 1 and FIG. 2, the fixed sleeve 10 is an upright hollow tube body, and a base 11 and a top cover 12 are respectively coupled to the upper and lower ends of the fixed sleeve 10; The sleeve 20 is slidably coupled to the inside of the fixing sleeve 10, and a receiving groove 21 is formed in the inside of the movable sleeve 20. The hydraulic oil 22 is filled in the receiving groove 21. A thread is provided on the outer peripheral surface of the top end of the movable sleeve 20.

As shown in FIG. 2 and FIG. 3, the limiting member 30 is disposed at the bottom of the movable sleeve 20 and is fixedly coupled to the base 11 of the fixing sleeve 10. The top end of the limiting member 30 is coupled with a limit. The plug 31 has an outer diameter slightly smaller than the inner diameter of the movable sleeve 20, and the limit stopper 31 abuts the inner bottom surface of the movable sleeve 20 when the movable sleeve 20 is moved to the uppermost position. In order to block the movable sleeve 20 from being detached, and at the same time restricting the stroke of the movable sleeve 20, in addition, the limit stopper 31 has a function of a piston, and can generate a hydraulic pressure for pushing the inside of the movable sleeve 20. The oil 22 is actuated to cause the movable sleeve 20 to produce a telescopic displacement effect.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the seat socket 40 includes a seat joint 41 , a fixed tube 42 connected to the seat joint 41 , and a piston rod 43 disposed inside the fixed tube 42 . And a set of elastic groups 44 disposed on the outer circumference of the fixed tube 42, wherein; The seat joint 41 is provided with a connecting base 411 for connecting the seat cushion at the top. A pivoting member 412 is pivotally disposed at a central portion of the seat joint 41, and a connecting tube is formed at the bottom of the seat joint 41. The seat joint 41 is screwed to the top end of the movable sleeve 20 by the connecting tube portion 413, and a fitting portion 414 is formed inside the connecting tube portion 413, and the fitting portion 414 is formed. a hollow tubular shape and a central portion, and is provided with a thread on the inner circumferential surface of the mounting portion 414. The fixing tube 42 is screwed and coupled to the fitting portion 414 of the seat joint 41, and is inserted into the movable sleeve 20 The inside of the fixed tube 42 is provided with a split ring 421. The split ring 421 is screwed to the fixed tube 42. The outer peripheral wall of the split ring 421 is sleeved and arranged side by side. An oil seal ring 4210, the outer ring of the split ring 421 abuts against the inner tube wall of the movable sleeve 20, and has an opening 4211 at a central position of the split ring 421, between the fixed tube 42 and the split ring 421 Two through holes 422 are provided around the opening, and the two through holes 422 are connected The opening 4211 of the split ring 421, when the opening 4211 is in an open state, the hydraulic oil 22 can flow from the two through holes 422 to the outer peripheral surface of the fixed pipe 42; the piston rod 43 is movably inserted into the fixed pipe The piston rod 43 includes a rod body 431, a piston rod 432 coupled to the front end of the rod body 431, and a set of return springs 433 disposed on the outer circumference of the piston rod 432. The piston rod 43 is The top end of the rod body 431 abuts against the bottom of the triggering member 412 of the seat joint 41. The piston rod 432 is coupled to the top end of the rod body 431 by a top end screw and is formed at the bottom end of the rod column 432. a mushroom-shaped plug portion 4321 having an outer diameter greater than an inner diameter of the opening 4211 of the split ring 421 so that the piston rod 432 passes through the split ring 421 and The plug portion 4321 is closed by the bottom of the split ring 421 to the opening 4211. The return spring 433 is placed against the bottom of the rod body 431 with the bottom portion, and the other end abuts against the inner peripheral wall of the split ring 421. When the trigger member 412 is pressed, the piston rod 432 will be interlocked downward, and when the trigger member 412 is released, the piston rod 432 is elastically restored to the original position by the return spring 433; The elastic group 44 includes a compression spring 441 and a compression sleeve 442. The compression spring 441 is elastically sleeved on the outer circumferential surface of the fixed tube 42 and is placed at the top end of the seat joint 41. The outer periphery of the compression sleeve 442 is disposed on the outer periphery of the compression sleeve 442. The compression sleeve 442 is sleeved on the outer circumference of the fixed tube 42 and disposed on the inner and outer peripheral surfaces of the bottom end of the compression sleeve 442. There are two oil seal rings 4420 arranged side by side for sealing the gap between the elastic group 44 and the fixed tube 42 and the movable sleeve 20.

The preferred embodiment of the present invention is as shown in FIG. 4 , and the present invention can be installed in a seat tube 51 of a frame 50 and can be coupled to a seat cushion 52 at the seat joint 41 when used. When the person sits on the seat cushion 52, the trigger member 412 of the seat joint 41 is pressed, and the movable sleeve 20 can be telescoped downward to the height to be adjusted by the user's own weight. On the other hand, when the trigger member 412 is pressed without applying gravity, the movable sleeve 20 is lifted to the height to be adjusted due to the pressure release; the detailed state of the internal actuation of the present creation is shown in FIGS. 5 to 7. As shown in FIG. 5 and FIG. 6, which is a state in which the movable sleeve 20 is adjusted downward, when the user sits on the seat cushion and applies downward pressure to the seat socket 40 and When the triggering member 412 is pulled at the same time, since the piston rod 43 will move downward to open the opening 4211 to form a passage, the liquid in the receiving groove 21 is allowed to be opened. The pressure oil 22 flows into the space between the split ring 421 and the compression sleeve 442 from the opening 4211 and the two through holes 422, and at the same time, the elastic force group 44 is subjected to the pushing of the hydraulic oil 22 by the downward pressure. The compression is generated and pressed in the direction of the seat joint 41. At this time, since the hydraulic oil 22 flows into the upper position of the split ring 421, the hydraulic oil 22 inside the accommodating groove 21 below the split ring 421 is caused. The volume is reduced, and the movable sleeve 20 is gradually retracted toward the fixed sleeve 10, while the movable sleeve 20 can be adjusted to the height required by the user until the bottom of the movable sleeve 20 reaches the fixed sleeve. The base 11 of 10 is either until the trigger member 412 is released.

As shown in FIG. 7, it is a state in which the movable sleeve 20 is adjusted upward. When the user raises the buttocks slightly so that the body gravity is not applied to the seat socket 40, the toggle is triggered at this time. The member 412 moves the piston rod 43 downward and opens the opening 4211. Since the compression spring 441 of the elastic group 44 is not pushed by the downward pressure, a rebound state is started, so that the original opening ring 421 is flown. The hydraulic oil 22 between the compression sleeve 442 is subjected to the pressure of the rebound, and begins to flow from the opening 4211 into the accommodating groove 21 below the split ring 421. At this time, the movable sleeve is made due to the hydraulic action. The tube 20 is extended upwards until the height the user desires to adjust.

In this way, the use of the present invention enables the user to press the trigger member 412 and match his own weight when riding, that is, the height of the seat to be reached can be quickly adjusted, and the vehicle can be adjusted without further adjustment. The height of the vehicle test is so troublesome. Further, the trigger member 412 can also be connected to the position of the bicycle brake through the wire, so that the user can adjust the seat height directly at the position of the control faucet, which is very convenient and practical. .

As mentioned above, it is only a preferred embodiment of the present creation, not the creation of this creation. Any form of limitation, any one of ordinary skill in the art, if the invention does not depart from the technical features of the present invention, the equivalent embodiment of the local modification or modification made by the technical content disclosed in the present invention is They are still within the scope of the technical features of this creation.
