Description

mechanical caliper

The present invention relates to mechanical calipers.

The mechanical caliper controls the swing of the lever through the brake wire, and then drives the internal pad (brake pad) to clamp the disc to achieve the purpose of braking. The thickness of the pad will gradually become thinner and thinner with the braking. After a certain level, it needs to be replaced with a new one. It is understandable that depending on the braking habits and different riding road conditions, the service life of the pads will also be greatly affected.

However, most riders wait until abnormal noise occurs when braking before replacing. Therefore, riders are often in danger due to low braking performance, or the caliper structure is excessively worn and needs to be replaced. condition. Only a small number of people will regularly maintain and check the thickness of the film through a ruler, but measuring the thickness through a ruler requires disassembling the caliper or surrounding components, which is quite troublesome and time-consuming.

Therefore, it is necessary to provide a novel and progressive mechanical caliper to solve the above problems.

The main purpose of the present invention is to provide a mechanical caliper, which can allow the user to visually judge the wear level of the pad from the outside, so as to quickly know whether to replace the pad.

In order to achieve the above object, the present invention provides a mechanical caliper, comprising: a caliper body and a pull rod, the caliper body includes a first marking part; the pull rod is pivotally connected to the caliper body, and can be operated relative to the caliper body by the outside. It swings between an initial position and a use position, and the deflection distance of the use position relative to the initial position increases with the wear of the pad, and includes a second marking part; wherein, when the pull rod swings from the initial position to In the use position, the second marking part moves a distance relative to the first marking part, and the distance is for the user to know the wear condition of the sheet by visual means; wherein, the first marking part and the first marking part One of the two marking parts is in the form of an energy bar, and the other is in the form of an indicator. With the change of the position of the indicator corresponding to the energy bar, the user can know the wear condition of the wafer.

The following examples are only used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

Please refer to FIGS. 1 to 4 , which show a first embodiment of the present invention. The mechanical caliper of the present invention includes: a caliper body 1 and a pull rod 2 .

Further, the caliper body 1 includes a first marking portion 11, and includes a related braking mechanism, such as a linkage mechanism, a brake pad, and the like. The pull rod 2 is pivotally connected to the caliper body 1, and can be swung relative to the caliper body 1 to an initial position and a use position by external operation, and the use position is the caliper body 1 when braking. The position of the disk, the yaw distance of the use position relative to the initial position increases with the wear of the sheet, the pull rod 2 includes a second marking part 21; wherein, when the pull rod 2 swings from the initial position to In the use position, the second marking portion 21 moves a distance 3 relative to the first marking portion 11 , and the distance 3 changes synchronously with the wear of the sheet, so the distance 3 can be visually observed by the user This method is used to know the wear condition of the pad without dismantling or measuring through a measuring ruler, which is convenient and quick and does not require the rider to have any professional skills to know whether it needs to be replaced or not.

More specifically, the first marking portion 11 is arranged on the outer surface of the caliper body 1 , and the second marking portion 21 is arranged on the outer surface of the tie rod 2 , through the surface arrangement, the structural arrangement of the components can be changed without affecting the The lowering comes to judge the wear of the piece, so the first marking part 11 and the second marking part 21 can be applied to various kinds of the mechanical caliper.

In the first embodiment, the pull rod 2 is pivotally connected to the caliper body 1 with an axis 6 as the axis, and the first marking portion 11 and the second marking portion 21 are respectively located on the axis 6 as the center of the circle. On the two virtual circles 7 arranged concentrically, the first marking part 11 and the second marking part move relative to each other in an arc-shaped path on the two virtual circles 7 . More specifically, the caliper body 1 further includes a pivot portion 12, and the pull rod 2 further includes two The arm portion 22 and a through portion 23 , a first end 221 of the two arm portions 22 is pivotally connected to and abuts against the pivot portion 12 , the through portion 23 is connected to a second end of the two arm portions 22 Between 222, the through portion 23 is used for the cable to be passed through and connected, the first marking portion 11 is arranged on the pivoting portion 12, the second marking portion 21 is arranged on the first end 221 of the arm portion 22, when the When the first end 221 rotates relative to the pivoting portion 12 with the axis 6 , the user can clearly identify and read.

More specifically, one of the first indicator portion 11 and the second indicator portion 21 is in the form of an energy bar, and the other is in the form of an indicator. Know the wear condition of the chip; wherein, the energy bar preferably includes a pattern layer 4, the pattern layer 4 extends along a moving direction 5 and produces a visual change, and the visual change includes color change, shading change, density change , at least one of shape change and brightness change, so as to further assist the user to know the relative position more quickly.

For example, but not limited to, in the first embodiment, the first indicator portion 11 is in the form of an energy bar, the second indicator portion 21 is in the form of an indicator, and the energy bar includes a plurality of dots 41 , the plurality of dots The 41 is gradually concentrated from sparse along the moving direction 5, whereby the user can know that the closer the plurality of dots 41 are concentrated, the more serious the wear degree and the thinner the thickness of the sheet.

Alternatively, as shown in the second embodiment shown in FIG. 5 and FIG. 6 , the first indicator portion 11A is in the form of an energy bar, and the second indicator portion 21A is in the form of an indicator. The difference from the first embodiment is that: The energy bar includes a plurality of unit bodies 42 , which are arranged at intervals along the moving direction 5 and shorten in sequence, so as to make the thickness of the sheet thinner and thinner for the user to know.

Preferably, the plurality of unit cells 42 are arranged at equal intervals, so as to present the effect of a relatively continuous phase change.

Alternatively, as shown in FIG. 7 and FIG. 8 , the third embodiment differs from the second and third embodiments in that: the first marking part 11B and the second marking part 21B are respectively index types, and the first marking part 11B and the second marking part 21B a sign 11B and the second marking portion 21B are spaced apart. When the pull rod 2 swings from the initial position to the use position, the second marking portion 21B approaches the first marking portion 11B. The closer the second marking part 21B is to the first marking part 11B, it means that the refill sheet is getting thinner and thinner, until the second marking part 21B and the first marking part 11B are aligned with each other, it means that the refill sheet needs to be replaced with a new one .

To sum up, the present invention provides a mechanical caliper, which allows the user to visually judge the wear level of the pad from the outside, so as to quickly know whether to replace the pad.
