Description

Brake joints that can be stably combined

The invention relates to an auto repair tool, and more particularly to a brake oil pipe joint that can be stably combined.

According to the disc brake mechanism that applies hydraulic pressure to the vehicle braking mechanism, after use, the wear of the sheet is generally visible to the naked eye, but the brake oil used to transmit the braking power is also susceptible to an increase in water content. The state of the brake power transmission, specifically, when the moisture content of the brake oil increases, the temperature rise of the brake oil caused by the brake process will cause the water to vaporize, and the gaseous water cannot be discharged in the closed brake oil pipeline system. In this way, the driving force exerted by the driver will cause the volume of the gaseous water to be compressed, and the power cannot be completely transmitted to make the braking mechanism act. As a result, the vehicle will fail and affect the driving safety.

Therefore, the replacement of brake oil is an important warranty for ensuring driving safety. As far as the general vehicle warranty technology is concerned, the replacement of brake oil is usually done by opening the bleeder on the brake caliper to make the brake oil Under the action of external pressure or vacuum suction, continuously flowing out from the discharge nozzle, in order to properly collect the outflowing brake oil or provide vacuum suction, the operation of connecting the pipeline to the discharge nozzle is a general known warranty procedure. User in the middle.

As far as the conventional pipe technology is used in connection with the nozzle, it is generally made by the pipe body constituting the pipe itself, or the pipe joint (1) having elasticity as shown in the first figure. The nozzle is elastically coaxially coated on the nozzle (2), and the crucible is tightly coupled to each other to achieve a joint state between the pipeline and the nozzle, but only by the tube or the elastic tube The bonding technology implemented by the joint (1) is easily weakened due to the weak bonding force between the joints (1), in particular, the pressure generated by the pedaling operation of the brake pedal of the vehicle, or via an external vacuum device. Pipeline The suction force formed when the vacuum suction operation is performed, the effect of these external forces is more likely to cause the loss of the conventional combined state, which affects the progress of the vehicle warranty operation.

Therefore, the main object of the present invention is to provide a brake joint that can be stably combined, which is coaxially coupled to the nozzle, so that the combination of the brake pipe joint and the nozzle is not affected by the pressure or suction.

Maintaining the state of integration with the conventional mouthpiece (2) is not as easy to disengage as the conventional technology, so as to ensure that the vehicle warranty operation is smooth and easy to use.

Continuing to refer to the seventh to ninth embodiments, in the second preferred embodiment of the present invention, a sturdy combination of the brake oil pipe joint (10 ' ) is provided, which is substantially the same as the first embodiment. The exposers are the same, and there are four differences:

The card portion (30 ' ) in this embodiment is disposed only on one side of the body portion (21 ' ), and is not on both sides as in the previous embodiment, so that the card portion (30) The number of components of the card body (31 ' ), the wing member (32 ' ), and the elastic member (33 ' ) are also only a single.

Second, embodiments of the present embodiment stanch sleeve (214 ') is the system to be in the shaft hole (22') axially slidable in the coupling state, accommodated in (22 ') of the shaft hole, and the second One end of the two-axis body (212 ' ) is coaxially abutted.

Thirdly, in this embodiment, the screw-joining state between the second shaft body (212 ' ) and the first shaft body (211 ' ) is changed by the user's hand to change the mutual The screwing state, that is, the depth at which one end of the second shaft body (212 ' ) is screwed into the first shaft body (211 ' ).

In this embodiment, the second shaft body (212 ' ) further includes a tubular threaded sleeve (2121 ' ) coaxially coupled to the first shaft body (211 ' ) at one end. A sleeve (2122 ' ) is coaxially sleeved in the threaded sleeve (2121 ' ) and has one end coaxially projecting out of the threaded sleeve (2121 ' ) for use with each of the collars (215), and a two-tight ring (2123 ' ) is coaxially sleeved on the sleeve (2122 ' ) and interposed between the sleeve (2122 ' ) and the threaded sleeve (2121 ' ), so that the sleeve (2122 ' ) At the same time as the screw sleeve (2121 ' ) is rotated, the airtightness of each of the close-contact rings (2123 ' ) is maintained.

Referring again to the tenth to twelfth drawings, the sturdy combination of the brake oil pipe joint (10 ' ) is used in combination with the outer connecting hose of the casing (2122 ' ). The operator then pulls the wing member (32 ' ) to rotate from the third position to the fourth position, and simultaneously slides the card body (31 ' ) from the first position to the second position. The shaft hole (22 ' ) is coaxially threaded over the conventional nozzle (2) as shown in the tenth figure.

When the operator releases the applied force, the wing member (32 ' ) is returned to the third position by the elastic action of the elastic member (33 ' ), and the card body (31 ' ) is reset to the reset position. In the first position, the card end (311 ' ) of the card body (31 ' ) is snapped onto the conventional mouthpiece (2), as shown in FIG. The mouthpiece (2) is firmly coupled to the body (20).

The operation system so far is similar to that described in the first embodiment, but the conventional mouthpiece (2) is subjected to the operation as shown in the tenth and eleventh embodiments. The card body (31 ' ) is locked and stably coupled with the body portion (20 ' ), but the gap between the leak stop sleeve (214 ' ) and the conventional leak nozzle (2) is not yet tightly coupled. In the first step, the operator inserts the body (20 ' ) into the conventional mouthpiece (2), since the leakproof sleeve (214) is not required to be tightly fitted to the conventional mouthpiece (2). As a result, a large external force is required, and therefore, its operation is relatively easy to implement.

Then, as shown in the twelfth figure, the operator further rotates to the screw sleeve (2121 ' ) with a freehand force to enlarge one end of the second shaft body (212 ' ) into the first shaft body. The depth in (211 ' ) is the same as that of pushing the stop sleeve (214 ' ) toward the conventional leaking nozzle (2), and the leakproof sleeve (214 ' ) is tightly sleeved on the conventional leaking nozzle (2). Ensure that the connection between the shaft hole (22 ' ) and the conventional nozzle (2) is kept airtight to avoid leakage.

Further, in terms of efficacy, the brake oil pipe joint (10 ' ) which can be stably combined in this embodiment can achieve the same effect as the previous embodiment, and can be stabilized by the brake oil pipe joint ( 10 ' ) before the combination with the conventional mouthpiece (2), the depth of the second shaft body (212 ' ) screwed into the first shaft body (211 ' ) is previously reduced, and the leakproof sleeve (214 ' ) is provided. Appropriate displacement space makes the conventional leaking nozzle (2) unobstructed in the action of penetrating the shaft hole (22 ' ), achieving the effect of labor saving and convenience.

Furthermore, the sturdy combination of the brake oil pipe joint (10 ' ) ensures the airtightness of the axial hole (22 ' ) and the internal space of the conventional vent (2) by rotating the screw sleeve ( 2121 ' ) to change the depth of the second shaft body (212 ' ) into the first shaft body (211 ' ) to be a walker. Therefore, in applying the force, the present embodiment adopts the technical content of the rotary propulsion, phase Compared with the technical content of the direct advancement adopted in the first embodiment, in addition to the labor-saving effect, by the operator's tightening operation, excessive force can be avoided to cause the leak-proof sleeve (214). ' ) is excessively in a deformed state of compression to protect the leak-proof sleeve (214 ' ) and prolong its service life.

More persons, by (212 ') of the threaded sleeve (2121' of the second shaft member) and the sleeve (2122 ') rotatable relative to one another between the pivotal state of the system can be avoided nut (2121') in rotation At the same time, the external hose that has been connected to the sleeve (2122 ' ) is twisted to ensure the safety of the working environment, which is also an effect that has not been achieved by the first embodiment.

In summary, the scope of the invention as specifically illustrated by the embodiments is to be construed as being within the scope of the claimed invention, and Changing, for example, the screw sleeve (2121 ' ) and the sleeve (2122 ' ) in the second embodiment are in a non-rotatable one-piece configuration, or the shape of the leak-proof sleeve (214 ' ) in the second embodiment is changed, The structure of the fastening portion (30) (30 ' ) in each of the embodiments is changed, and any person who has obtained the patent coverage of the present application shall be protected by the case.
