2. Description of the Prior Art
Cylinders for disc brakes are commonly used in lots of transportation, and the hardest and the most critical part of dis/assembling brake cylinders is adjusting and dis/assembling valves.
A brake cylinder adjuster generally includes a pulling plate able to be axially jointed with a brake cylinder, and a driving wrench able to rotate, shift axially and connect to the brake cylinder. A hollow cylindrical positioning shaft protrudes upward at a dead center of a surface of the pulling plate. The outer diameter of positioning shaft corresponds to the inner diameter of the opening end of central valve of the brake cylinder. In this way, the positioning shaft can be inserted precisely into an opening end of the central valve of the brake cylinder, and a reserved positioning column abuts a recess on a side of the brake cylinder so as to dis/assemble the brake cylinder. The prior art is disclosed in TW392552.
However, the size of the positioning shaft of the conventional brake cylinder adjuster is fixed, thus the adjuster can not adjust vehicle cylinder having different-sized valve openings. Besides, the prior art is bigger, heavier and thicker. In addition, the abutting structure is only disposed on a single side of the conventional brake cylinder adjuster, thus the valve having a different number of the notches is unable to be dis/assembled.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a installation device for a vehicle cylinder, able to adjust the distance between abutting columns according to different-sized vehicle cylinder valves. The invention provides a simple structure, light weight, small volume and thin thickness of installation device for a vehicle cylinder, and can be applied to a variety of different-sized vehicle cylinders. In addition, two sides of the device are relatively provided with different numbers of abutting columns so as to be applied for dis/assembling the valves having different numbers of the notches.
To achieve the above object, an installation device for a vehicle cylinder in accordance with the present invention includes a main body, at least one lateral member and a plurality of swingable abutting members. The main body has an assembling portion for a driving mechanism to be assembled thereto. The lateral member is on a side of the main body and rotatably coupled to the main body. A plurality of radial sliding slots is disposed on the lateral member relative to a center of the lateral member. The swingable abutting members are disposed between the main body and the lateral member. Each said swingable abutting member includes a connecting rod and an abutting column. An end of each said connecting rod is pivoted to the main body to form a first pivoting portion. The other end of each said connecting rod is connected to the abutting column. A rotating central portion is defined between the first pivoting portions, each said abutting column protrudes outside of the lateral member and is slidably disposed in one said sliding slot. Each said abutting column is provided for being assembled to a notch of a valve to be abutted of a vehicle cylinder, and each said swingable abutting member swings pivotally about the rotating central portion with the first pivoting portion as a pivoting center.
To achieve the above object, an installation assembly for a vehicle cylinder having the installation device in accordance with present invention further includes a driving mechanism. The driving mechanism includes a rod body, a kit screwed to the rod body and a driving member. An end of the rod body is unrotatably assembled to the assembling portion. The kit is radially formed with a blocking portion, and the blocking portion for being situated between a caliper of the vehicle cylinder and the valve to blockably abut against the caliper. The driving member is laterally connected to the rod body and able to rotate the rod body.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

The main body 10 has an assembling portion 11 for a driving mechanism to be assembled thereto. For example, the assembling portion 11 can be a polygonal cavity or through hole, or even a polygonal column.
At least one said lateral member 20 is on a side of the main body 10 and rotatably coupled to the main body 10. A plurality of radial sliding slots 21 are disposed on the lateral member 20 relative to a center of the lateral member 20, wherein the radial sliding slots 21 are equiangularly arranged on the lateral member 20.
The swingable abutting members 30 are disposed between the main body 10 and the lateral member 20. Each said swingable abutting member 30 includes a connecting rod 31 and an abutting column 32. An end of each said connecting rod 31 is pivoted to the main body 10 to form a first pivoting portion 33, and the other end of each said connecting rod 31 is connected to the abutting column 32. A rotating central portion 34 is defined between the first pivoting portions 33. Each said abutting column 32 protrudes outside of the lateral member 20 and is slidably disposed in one said sliding slot 21. Each said abutting column 32 is provided for being assembled to a notch of a valve to be installed into the vehicle cylinder, and each said swingable abutting member 30 is swingable around the rotating central portion 34 with the first pivoting portion 33 as a pivoting center. The swingable abutting member 30 can be integrally formed.
In this embodiment, each of two opposite sides of the main body 10 is coupled with one said lateral member 20. A number of the swingable abutting members 30 disposed on one of the two opposite sides of the main body 10 is different from a number of the swingable abutting members 30 disposed on the other of the two opposite sides of the main body (2 and 3, relatively), that is, the invention can be applied for dis/assembling the valves having different numbers of the notches. Specifically, the main body 10 has a plurality of pivoting holes 12 thereon, and each said swingable abutting member 30 has a pivoting column 35 disposed in each said pivoting hole 12. In other embodiments, the main body 10 can have pivoting columns thereon, and each said swingable abutting member has a pivoting hole. Preferably, the lateral member 20 is provided with an annular recess 22, the main body 10 is provided with a protruding column 13 penetrating the annular recess 22, the protruding column 13 is provided with the assembling portion 11, and a connecting portion is assembled to the protruding column 13 and blockably disposed in the annular recess so as to couple the main body 10 with the lateral member 20. Therefore, the overall thickness gets thin, and the assembling area can be protected. For example, the connecting portion includes a snap ring 14 radially disposed on a clamping groove 15 around one end of the protruding column 13, but is not limited thereto. After assembling, the installation device for a vehicle cylinder 1 is overall similar to a disc shape.
