Description

Mechanical caliper

Technical Field

The present invention relates to mechanical calipers.

Background

The mechanical caliper controls the pull rod to swing through the brake so as to drive a disc at the position where an inner brake pad (brake pad) is clamped to achieve the purpose of braking, wherein the thickness of the brake pad is gradually abraded and thinned along with the braking, and a new product needs to be replaced after the abrasion is reduced to a certain degree. It can be understood that the service life of the brake pad is greatly influenced according to different braking habits and riding road conditions.

However, most of the riders are replaced when the brake is abnormal, so that the riders are often dangerous due to the low braking performance or need to be replaced entirely due to the excessive wear of the caliper structure. Only a few people can maintain the caliper regularly and check the thickness of the linen pad through the measuring ruler, but the caliper or surrounding components are needed to be disassembled through measuring the thickness through the measuring ruler, which is quite troublesome and time-consuming.

Therefore, there is a need for a new and improved mechanical caliper to solve the above problems.

The pull rod 2 is pivoted to the caliper body 1 and can swing relative to the caliper body 1 to an initial position and a use position under the action of external operation, the use position is the position of a brake pad of the caliper body 1 when clamping a disc when braking, the deflection distance of the use position relative to the initial position is increased along with the abrasion of the brake pad, and the pull rod 2 comprises a second marking part 21; when the pull rod 2 swings from the initial position to the use position, the second indication part 21 moves a distance 3 relative to the first indication part 11, and the distance 3 changes with the abrasion of the linen pad synchronously, so that the distance 3 can be used for a user to know the abrasion of the linen pad in a visual way without disassembling or measuring through a measuring ruler, namely, the user can know whether the linen pad needs to be replaced conveniently and quickly without any professional technology.

More specifically, the first indication portion 11 is disposed on the outer surface of the caliper body 1, and the second indication portion 21 is disposed on the outer surface of the pull rod 2, so that the wear of the pad can be determined without changing the structural configuration of the components, and thus the first indication portion 11 and the second indication portion 21 can be applied to various mechanical calipers.

In the first embodiment, the pull rod 2 is pivotally connected to the caliper body 1 with an axis 6 as a center, the first indication portion 11 and the second indication portion 21 are respectively located on two virtual circles 7 concentrically arranged with the axis 6 as a center, and the first indication portion 11 and the second indication portion respectively perform arc-shaped path movements on the two virtual circles 7 relatively. More specifically, the caliper body 1 further includes a pivot portion 12, the pull rod 2 further includes two arms 22 and a penetrating portion 23, a first end 221 of the two arms 22 is pivotally connected to and abutted against the pivot portion 12, the penetrating portion 23 is connected between a second end 222 of the two arms 22, the penetrating portion 23 is for the rope to penetrate and connect, the first marking portion 11 is disposed on the pivot portion 12, the second marking portion 21 is disposed on the first end 221 of the arm 22, when the first end 221 rotates relative to the pivot portion 12 about the axis 6, the user can clearly identify and read the first end 221.

More specifically, one of the first indication portion 11 and the second indication portion 21 is an energy bar type, and the other is an index type, so that along with the position change of the index corresponding to the energy bar, the wear condition of the linen pad can be known to the user; the energy bar preferably includes a pattern layer 4, the pattern layer 4 extends along a moving direction 5 and generates a visual change, and the visual change includes at least one of a color change, a shade change, a density change, a shape change, and a brightness change, so as to further assist a user to know a relative position more quickly.

Further alternatively, as shown in fig. 5 and fig. 6, in the second embodiment, the first indicator 11A is in an energy bar type, and the second indicator 21A is in an index type, which is different from the first embodiment in that: the energy bar comprises a plurality of units 42, the plurality of units 42 are arranged at intervals along the moving direction 5 and are sequentially shortened, thereby realizing that the thickness of the linen is thinner and thinner for users to know.
