Description of the Invention: [Technical Field] The present invention relates to a seat cushion height adjusting structure, and particularly to a bicycle seat tube, which utilizes a combination of oil pressure and air pressure to design a structure to make a bicycle The height of the seat cushion can be used as a change adjuster. [Prior Art] • ▲The bicycle must be selected according to the height of the rider at the time of purchase. The intention is to correct the posture when riding, so as to avoid the acid suller injury; the bicycle seat cushion is the madness of the county. Importantly, the appropriate seat height is the state in which the entire leg is straight but not tight when the pedal is at the lowest point to maintain the correct posture for riding. The industry is not able to tailor the frame to each individual's height. The customized production process requires considerable manufacturing costs and is not economical. Therefore, it is now widely used in the custom-made car industry. The structure of the height can solve this problem. At present, the height adjustment structure of the seat cushion is mostly disposed in the seat tube and the seat cushion riser of the bicycle frame. According to the structure, it can be roughly classified into "mechanical", "gas-oil type", and "hybrid type", etc. "Mechanical" uses the action of certain mechanical characteristics to adjust the relative height position between the seat tube and the seat riser; the "gas-oil pressure type" is used to utilize the gas or oil house components, or both. The action is taken to adjust the relative height position between the seat tube and the seat tube riser; the "mixed type" is combined with the two structural applications [S1 3 201217208 "Mechanical" and "Gas-oil-pressure". The relative height position between the tube and the seat tube riser. Further analysis of the seat cushion height adjustment structure of "gas-oil pressure type" mainly uses the gas compressible characteristics, and the hydraulic oil flows in the space to change, so that the seat and the seat cushion stand for relative position. The linear change causes the seat cushion mounted on the seat riser to achieve a height adjustment effect. According to the conventional method of "gas-oil type", the height-adjusting structure of the seat cushion is disclosed in the "No. Descending suspension seat tube structure" disclosed in the Japanese Patent No. 089221346, which comprises a locking seat and is respectively disposed at The middle of the locking seat and one of the lower handle and the guide rod are provided with a through hole in the center of the guide rod, and are slidably arranged by a guiding rod, and one end of the guiding rod passes through the central operating hole of the locking seat, and Abutting against one end of the pull handle; a return spring disposed between the pull handle and the lock seat at the front end of the guide rod; a hollow shaft tube sleeved outside the guide rod, and sleeved on the a pressure tube in the hollow shaft tube, and an actuating plug under the guide rod and sliding in the pressure tube; the front and rear actuating rods are abutted in the movable plug, and the front and rear actuating rods are matched with a plurality of liquid oxygen The pressure ring and the pressure control hole control the operation of the guide rod; the sleeve is sleeved on the upper end of the hollow shaft tube; a screw is inserted into the screw hole on the two sides of the head housing receiving groove; The outer diameter can be forced into the hollow shaft tube, and the insert on the rear side is embedded in the hollow shaft tube. Inside the hole. Another type of seat cushion height adjustment structure which is known as "gas-oil type", such as the "adjustable bicycle seat cushion riser structure" disclosed in the Japanese Patent No. 097206782, which mainly includes a riser tube. A pipe body with a preset length; a ^ 4 201217208 pipe is a pipe body in which the upper and lower displacement of the inner edge of the pipe is connected with a pad and is set in the pipe. The base pipe having a fixed state with the riser is a cylindrical shape with an opening facing upward, and an adjusting pipe '-adjusting seat is disposed therein, and is disposed under the adjusting pipe and linearly displaced therefrom The adjusting seat is formed in the base pipe to form an upper liquid space and a liquid 1 adjustment "IL system is formed between each of the adjusting tube and the adjusting seat to connect the upper and lower buttons, and the adjusting rod is arranged. The upper and lower displacements are made in the entire tube, so that the adjustment flow path is switched between flowing and non-circulating, whereby the seat tube simultaneously generates an action of moving up and down and between the vertical tubes and the base tube. SUMMARY OF THE INVENTION In the above structure, the structure is mainly used in the hollow shaft tube, the pressure tube is still worn, and the front and rear actuating rods in the pressure tube are matched with a plurality of liquid pressure rings to cause the guide rod to be tight or Under pressure, the person can adjust the lift directly by the handle; the latter structure is based on the adjustment valve stem, which is placed in the adjustment tube for up-and-down displacement, so that the adjustment flow path is switched between circulation and non-circulation. The seat tube is connected between each of the riser and the base pipe to generate an action of up and down movement and rest, thereby achieving an adjustment of the up and down displacement of the bicycle seat cushion. Further analysis of the oil circuit structure of the two, although the former structure defines a plurality of liquid pressure rings 'but not its pressure (four) (4) or where the secret oil is filled, nor does it disclose the gas or the oil lying on the knot The entire space of the paste is separated from the upper and lower liquid spaces, and the adjustment valve stem can be moved up and down with the adjustment valve rod [5 201217208 Blocking the adjustment flow path to produce a state of circulation and non-circulation, so that the officers Whether the riser and the base officer can control the corresponding position change. Since the hydraulic oil must flow between the two oil chambers to balance the internal pressure, there is no short-term _ force difference on both sides of the valve block _ fast flow, the job is easy to generate cavitation phenomenon, that is, its - air chamber shirt and pressure Part of the vacuum occurred, so that the height-adjusted wire was used as a delay, ship; shame, the inventor of the case believed that the oil circuit structure was still improved under the condition that the seat tube and the seat tube were not changed in size.

In order to further understand the structural features, technical means and desired effects of the present invention, the mode of use of the present invention will be described as follows: The present invention is characterized in that the inner tube (20) is provided with the piston seat (21) And extending into the outer tube (10), and forming an outer air chamber (22) between each of the lower seat (11), the inner wall of the outer tube (1〇), and the piston seat (21) Fill the gas with a preset pressure. According to the present invention, the oil passage outer tube (31) that is sleeved with the floating piston seat (32) is disposed inside the inner tube (20) through the 201217208. The floating piston seat (32) is the inner tube (2〇). The partition is two spaces, wherein the outer oil chamber (33) is formed between the piston seat (21), the inner tube (2〇) inner wall, the outer wall of the oil passage outer tube (31), and the floating piston seat (32). And filling the hydraulic oil with a preset pressure therein; on the other side of the floating piston seat (32), the outer wall of each of the nozzle group (50), the inner tube (20), and the outer wall of the oil passage (31) The inner air chamber (34) is formed between the floating piston seat (32) and filled with a predetermined pressure gas. The valve block (36) of the present invention is disposed inside the outer pipe (31) of the oil passage, and the valve seat (36) partitions the inner portion of the outer pipe (31) into a space and a passage. The inner oil chamber (37) is formed between each of the valve seat (361), the inner wall of the oil passage outer tube (31) and the gas nozzle group (10), and is filled with hydraulic oil of a preset pressure; the valve seat (361) The oil passage (38) is formed between the valve seat (361), the inner wall of the oil passage outer tube (31), the outer wall of the oil passage inner tube (35), and the piston seat (21) on the other side, and can be respectively connected to Each of the outer oil chamber (33) and the inner oil chamber (37). The oil passage (38) path of the present invention is passed through the through hole (367) through the inner oil chamber (37) into the valve sleeve (366) 'when the stem (364) of the valve stem (364) is When in the open state, the hydraulic oil flows into the valve seat (361) and enters the oil passage (38) through the passage (362), and finally communicates to the outer oil chamber (33); therefore, the hydraulic oil can be supplied to the hydraulic oil. (37) Flow to the outer oil chamber (33), or the outer oil chamber (33) may be returned to the inner oil chamber (37). When the present invention is to perform the twist adjustment operation, the valve stem (364) is linearly displaced toward the valve sleeve (366) by the control group (3 ribs), and the stopper portion (3 (6) leaves the valve seat (361). The inner surface of the rim is opened, and the oil passage (10) is not in the flow state. The hydraulic oil can flow from the inner oil chamber (37) to the outer oil chamber (33). Or returning from the outer oil chamber (33) to the inner oil chamber (37), the inner tube (20) can be linearly displaced in the outer tube (1〇) to produce a relative position change. Height adjustment. Further explaining that 'when the height is to be lowered', the inner tube (2〇) is moved toward the outer tube, the space in the outer air chamber (22) is reduced, and the inner oil chamber (37) is due to the valve group (36) taking up space and gradually reducing the space. At this time, the hydraulic oil in the inner oil chamber (37) starts to enter from the inner oil chamber (37) through each of the oil passages (38) and the valve group (36). The outer oil chamber (33), therefore, when the pressure of the outer oil chamber (33) increases, the floating piston seat (32) begins to move toward the inner air chamber (34). When the height is to be raised, the inner tube (2〇) is stretched and moved outwardly of the outer tube (1〇), the space in the outer air chamber (22) is enlarged, and the inner oil chamber (37) The space gradually increases due to the removal of the space of the valve block (36), at which time the pressure of the inner oil chamber (37) becomes smaller. Therefore, the hydraulic oil starts to flow from the outer oil chamber (33) through each of the oil passages ( 38) and the valve block (36) enters the inner oil chamber (37), so when the pressure of the outer oil chamber (33) is reduced, the floating piston seat (32) starts to move toward the outer air chamber (22) . When the height adjustment is to be positioned, the valve stem (364) is linearly displaced in the opposite direction of the valve sleeve (366) by the control group (363), and the stopper (365) abuts against the wide seat (361). The inner surface of the rim is not opened. At this time, the oil passage (38) is blocked, and the hydraulic oil is unable to flow, so that the inner and outer oil chambers (37) and (33) are inside. The outer air chamber (34) (22) is in a state of pressure balance, and the inner tube (20) cannot be positioned linearly displaced in the outer tube (1〇). The invention has a double inner tube design, and a 201217208 oil passage outer tube (31) is mainly disposed inside the inner tube (2〇), and the valve group (10) is disposed in the outer tube (8) of the oil passage and simultaneously forms the inner oil. The technical characteristics of the chamber (37) are two paths, one of which is to open and close the communication state of the oil passage (38), and the other is to increase the stroke of the oil passage (38) in which the inner and outer oil chambers (10) (10) are connected. Using an oil pipe (8) with a considerable length of the outer pipe (8) to form a shaft oil chamber (37) Yang Lu (10), the shape of the part of the barrier effect of the indirect flow, the fuel hydraulic oil spine distance field is small (38) In order to reach the inner and outer oil chambers (37) (33), the natural flow velocity is slow and the pressure and force changes are relatively stable, and the cavitation phenomenon is not easy to occur, and the inner pipe (20) is delayed. It is viscous and cannot move, so it can effectively improve the efficiency of the height adjustment action. On the other hand, by increasing the design of the double inner tube structure of the hydraulic oil stroke, it means that the inner tube (20) (4) is provided with an oil tube (31), and the valve group is disposed in the outer tube (8) of the oil passage ( 36) At the same time, the technical characteristics of the inner oil chamber (37) are formed, which can reduce the phenomenon of internal vibration of the hydraulic oil due to the excessive flow rate, so as to reduce the internal collision of the oil and the oil. , increasing the service life of the component, the setting of the gas tilting (9)) of the present invention, the main contact - the filling gas can enter the portion of the inner air chamber (34), thereby achieving the effect of adjusting the internal air pressure of the inner air chamber (34) . The floating piston seat (32) of the present invention is designed to provide an automatic "pressure" adjustment function for both the outer oil chamber (34) and the inner air chamber (34) on both sides thereof, and on the other hand Both sides of the gas or hydraulic oil have the effect of reducing the internal oscillation of the fluid when the pressure difference changes, and provide a voltage stabilization effect in a timely manner. [s] 12 201217208 The present invention is designed for the elastic member (368) of the valve block (36), wherein when the valve stem (364) is displaced toward the valve sleeve (366), the control group (363) is released. When the valve stem (364) is applied, the elastic member (367) provides a natural elastic force to reset the valve stem (364) until the stopping portion (365) abuts against the end edge of the valve seat (361), so that The oil passage (38) is in a non-circulating state. Please refer to the ninth to twelfth drawings, which are another embodiment of the present invention, wherein the oil passage outer tube (31) is integrally formed with a closed shape with respect to the other end of the piston seat (21); The valve control device (30) further has an elastic member (39) disposed in the inner air chamber (34) and abutting on one end of the floating piston seat (32) to provide a linear reset action. The pressure between the inner air chamber (34) and the outer oil chamber (33) on both sides of the floating piston seat (32) is balanced. In this embodiment, the elastic force of the elastic member (39) is used instead of the preset air pressure of the inner air chamber (34), which is a hybrid application of the "mechanical" and "gas oil pressure" structures; In the embodiment, the use of the nozzle group (5〇) can be omitted, and the air pressure addition operation is not necessary because the air pressure of the inner air chamber (34) is insufficient. At the same time, in the embodiment, the outer pipe (31) of the oil passage can be formed in an integral closed shape at one end to ensure that the liquid waste oil of the inner oil chamber (37) is not exposed; The set, the actuating relationship, and the intended effect are all identical to the best embodiment. Referring to the thirteenth to fifteenth drawings, in another embodiment of the present invention, the elastic member (368) is disposed inside the valve sleeve (366), and the two ends thereof are respectively abutted on the respective ones. Between the valve seat (361) and the stem of the valve stem (364), the valve stem (364) is provided with a returning elastic force; the stopping portion (365) is disposed at a middle portion of the valve stem (364) close to the m 13 201217208 The flow passage exit portion of the seat (361), and the linear displacement of the valve stem (364) can synchronously drive the stop portion (365) to move to make the flow passage in the valve seat (361) flow or No flow status switching. The actuation direction of this embodiment is opposite to the preferred embodiment. When the adjustment operation is to be performed, the valve stem (364) is linearly displaced toward the valve seat (361) by the control group (363). The stop portion (365) enters the valve seat (641) from the edge of the valve seat (361) to open the inner flow passage, and the oil passage (38) is in a flow state without being blocked. The hydraulic oil may flow from the inner oil chamber (37) to the outer oil chamber (33) or from the outer oil chamber (33) to the inner oil chamber (37), then the inner tube (20) may be The outer tube (1〇) is linearly displaced to produce a relative position change, which can be adjusted for height. When the height adjustment is to be positioned, the valve stem (364) is linearly displaced in the opposite direction of the valve seat (361) by the control group (363), or the control group (363) is released from the valve stem (364). Applying force, the elastic member (368) provides a natural elastic force to reset the valve stem (364) to the stop portion (365) to block the flow passage of the valve seat (361), and the oil passage is at this time (38) is in a non-circulating state, and the hydraulic oil cannot flow, so that the inner and outer oil chambers (37) (33) and the inner and outer air chambers (34) (22) are in a state of pressure balance. (20) It is impossible to position the linear tube in the outer tube (1〇). The assembly, actuation relationship, and expected performance of this embodiment are identical to those of the preferred embodiment.
