The specific embodiment
The present invention is relevant for a kind of concealed purt oil device that takes shape in the bicycle oil pressure brake of bicycle handle end, see also Fig. 1, shown in Figure 2, the present invention mainly in the terminal inner shafts of bicycle handle 40 to an adjacent oil resevoir 10 and the master control cylinder pressure 20 of being formed with, both also interconnect by one first oilhole 11 and one second oilhole 12, because the mode of processing, the opening 101/201 of this oil resevoir 10 and master control cylinder pressure 20 all is located at the end from handlebar 40, process aforementioned first oilhole 11 and second oilhole 12 again for convenience, this oil resevoir 10 is formed with a perforation 13 in corresponding first oilhole 11 and second oilhole, 12 places, make the builder can utilize drilling machine or other suitable processing modes to process this first oilhole 11 and second oilhole 12, after completion of processing, this perforation 13 utilizes a lid 14 hermetic closed; In addition, being provided with an airtight capping 15 in the opening 101 of oil resevoir 10 uses oil resevoir 10 complete closed.The end of this handgrip is provided with a pair of lug 16 and uses the L shaped control lever 30 of controlling master control cylinder pressure 20 that is pivoted to overhanging.
Be equiped with a spring 21, a piston 22, an operating bar 23 and a retaining piece 24 in this master control cylinder pressure 20 in regular turn.This retaining piece 24 is that blocking is positioned on the inwall of master control cylinder pressure 20, uses and avoids breaking away from spring 21, piston 22 and the operating bar 23 autonomous pressure control cylinders 20.The two ends system of this spring 21 axially pastes the end face that is butted on master control cylinder pressure 20 ends and piston 22 respectively.The two ends of this piston 22 are equiped with respectively pastes first oil sealing 221 and second oil sealing 222 that is butted on master control cylinder pressure 20 inwalls, and 221,222 on two oil sealings then are formed with a circular groove 223, wherein, when control lever 30 is not exerted pressure, this first oil sealing 221 is between first oilhole 11 and second oilhole 12, and the stroke perseverance of this second oil sealing 222 does not surmount second oilhole 12.This first oil sealing 221 is mainly in order to the start oil in the compression master control cylinder pressure 20 and utilize oil pipe 202 that it is delivered to the brake device of bicycle, and the stroke perseverance of second oil sealing 222 not surmount second oilhole 12 mainly be to avoid the start oil in the oil resevoir 10 to see through second oilhole 12 and seepage; Pull and then be hubbed on the L shaped control lever 30 in its other end of the end of piston 22 in the one end system top of this operating bar 23.
See also as shown in Figure 3, when the user depresses control lever 30, the operating bar 23 that is hubbed on control lever 30 can inwardly promote piston 22 and compression spring 21, when the stroke that moves when first oil sealing 221 surpasses first oilhole 11, the start oil of pressurized flows into oil resevoir 10 via first oilhole 11 in the master control cylinder pressure 20, oil pressure in the oil resevoir 10 can raise slightly at this moment, force the start oil of part in the oil resevoir 10 to flow in the circular groove 223 of piston 22 via second oilhole 12, at this moment, second oil sealing 222 can avoid the start oil in the circular groove 223 outwards to ooze out, after the stroke of first oil sealing 221 surpasses first oilhole 11, the start oil of pressurized can only flow to brake device via oil pipe 202 in the master control this moment cylinder pressure 20, and constantly the oil pressure that raises then forces brake device that bicycle is produced brake action.When user's unclamp operation bar 30, because the effect of spring 21 restoring forces, force piston 22 to move the pressure that discharges start oil in brake device and the oil pipe 202 backward, when the stroke that retreats when piston 22 surpasses first oilhole, can in oil resevoir 10, produce a negative pressure appearance, and then the start oil in the circular groove 223 is sucked back in the oil resevoir 10 via second oilhole 12.
See also as Fig. 4, shown in Figure 5, it applies to the enforcement aspect of various different car types for the present invention.As shown in Figure 4, the present invention is used in sports and uses bicycle, and wherein, this handlebar 40 ' is the upwardly extending forward design of employing, in order to reducing windage; And for example shown in Figure 5, the present invention system is installed on the handgrip of bicycle for mountain-climbing or Regular Bicycle, wherein, this handlebar 40 " be a horizontal body of rod.
In sum, the present invention has following advantage at least:
1. the designs simplification assembling easily: because the present invention system takes shape in the terminal inboard of bicycle handle, therefore, designs simplification does not need other registration devices to fix, and therefore the upright process of group is more or less freely.
2. reduction die cost: because the present invention system takes shape in the terminal inboard of bicycle handle, therefore, except that control lever 30, do not need other die sinking manufacturing, can reduce the die cost of development.
The above embodiment is not in order to restriction the present invention, so the displacement of the change of numerical value or equivalent elements must be subordinate to category of the present invention such as only in order to explanation the present invention.
