Abstract
The utility model aims at providing a special ruler which can quickly and accurately measure the clearance of a wheel cover of an automobile. The special ruler for measuring the clearance of the wheel cover of the automobile comprises a base and a calibrated scale fixed on the base; and the key point lies in that: the calibrated scale is sequentially provided with a wheel center positioning pointer which can slide on the calibrated scale, a positioning plate for the upper surface of a tire and a wheel cover height positioning pointer from bottom to top. In the special ruler for measuring, by arranging the wheel center positioning pointer, the positioning plate for the upper surface of the tire and the wheel cover height positioning pointer, the special ruler for measuring can be accurately positioned, and the height of the wheel cover, the height of the tire surface and the height of the wheel center can be measured by one-time operation, thus improving measuring efficiency and accuracy.
Description
Technical field
The utility model relates to the survey instrument in a kind of measured automobiles wheel cover gap.
Background technology
The common height gauge of existing use usually comes measured automobiles wheel cover gap, as shown in Figure 1, this height gauge can not directly be measured the wheel cover gap, but must measure the terrain clearance of wheel cover and the terrain clearance of tire upper surface earlier, calculate difference then, the measuring process complexity can not obtain the result apace; All to move ruler when measuring each parameter in addition, reference point is changed; The upper surface of tire is a disc, and the pointer of height gauge can not well be positioned at the last circular surfaces of tire, promptly is not easy to obtain real tire peak, and these all can cause the deviation of measurement result.
The utility model content
The purpose of this utility model is the measurement special ruler that proposes a kind of wheel cover of measured automobiles quickly and accurately gap.
The measurement special ruler in automobile wheel cover of the present utility model gap comprises base and the rule that is fixed on the base, and key is to be disposed with from the bottom to top on the described rule core wheel positioning pointer, tire upper surface location-plate and the wheel cover height positioning pointer that can slide on rule.
During measurement, concordant base with the bottom surface of doughnut, the core wheel positioning pointer is pushed up the center of the wheel of getting on the car, again wheel upper surface location-plate is placed on the tire upper surface, at last the wheel cover height is measured the upper limb of pointed wheel cover, after all pointers and location-plate were reserved a little, survey crew just can directly obtain the height of each point from rule, obtain measured wheel cover gap directly, accurately.
Core wheel positioning pointer, tire upper surface location-plate and the nonvoluntary slip of wheel cover height positioning pointer when measuring for making, influence measurement accuracy, described core wheel positioning pointer, tire upper surface location-plate and wheel cover height positioning pointer be provided with can self and rule is fixing locking structure.
Above-mentioned locking structure is made of mounting groove that is clipped in the rule both sides and the locking cam that is movably arranged in the mounting groove, and described locking cam and core wheel positioning pointer or tire upper surface location-plate or wheel cover height positioning pointer are separately positioned on the relative both sides of rule.After pointer or location-plate are had good positioning, the locking cam is turned over certain angle, because the surface of cam is the asymptotic line shape, so the locking cam can cooperate pointer or location-plate that rule is clamped, the dynamics that clamps is controlled by the angle that the locking cam turns over, and above-mentioned locking structure is easy to operate, simple in structure.
Because the side of wheel cover usually and the side of tire not at grade, can aim at wheel cover better for making wheel cover height positioning pointer, described wheel cover height positioning pointer is preferably telescopic structure, specifically can followingly be provided with: described wheel cover height positioning pointer comprises pointer groove and the pointer that can slide on the pointer groove.
Described tire upper surface location-plate is a curved-surface structure, the radian size of its curved surface can be provided with according to the radian of concrete tire, like this when location-plate and surface of tyre applying, represent that promptly location-plate has been positioned at the last circular surfaces of tire, be that location-plate has been in real tire peak, therefore can reduce measuring error.
The measurement special ruler in automobile wheel cover of the present utility model gap is by being provided with core wheel positioning pointer, tire upper surface location-plate and wheel cover height positioning pointer, can allow the measurement special ruler locate exactly, and can once just measure wheel cover height, tread thickness and core wheel height, improved efficient and the accuracy measured.

Embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 2, the measurement special ruler in the automobile wheel cover gap of present embodiment comprises base 1 and the rule 6 that is fixed on the base, is disposed with core wheel positioning pointer 2, tire upper surface location-plate 3 and the wheel cover height positioning pointer 4 that can slide on rule 6 on the described rule 6 from the bottom to top; Described core wheel positioning pointer 2, tire upper surface location-plate 3 and wheel cover height positioning pointer 4 be provided with can self and rule 6 is fixing locking structure 5.
As scheme above-mentioned locking structure 5 and constitute by mounting groove 51 that is clipped in the rule both sides and the locking cams 52 that are movably arranged in the mounting groove 51, described locking cam 52 and core wheel positioning pointer 2 or tire upper surface location-plate 3 or wheel cover height positioning pointer 4 are separately positioned on the relative both sides of rule 6.After pointer or location-plate are had good positioning, locking cam 52 is turned over certain angle, because the surface of cam is the asymptotic line shape, so locking cam 52 can cooperate pointer or location-plate that rule 6 is clamped, the dynamics that clamps is controlled by the angle that locking cam 52 turns over, and above-mentioned locking structure is easy to operate, simple in structure.
Described wheel cover height positioning pointer 4 comprises pointer groove 41 and the pointer 42 that can slide on pointer groove 41, so that wheel cover height positioning pointer 4 can be aimed at wheel cover better.
During measurement, concordant base 1 with the bottom surface of doughnut, with the center that core wheel positioning pointer 2 is pushed up the wheel of getting on the car, utilize locking cam 52 with 2 lockings of core wheel positioning pointer; Again wheel upper surface location-plate 3 is placed on the tire upper surface, utilizes locking cam 52 3 lockings of wheel upper surface location-plate; At last the wheel cover height is measured the upper limb that pointer 4 points to wheel covers, utilize locking cam 52 that the wheel cover height is measured pointer 4 lockings; After all pointers and location-plate were reserved a little, survey crew just can directly obtain the height of each point from rule 6, obtain measured wheel cover gap directly, accurately.
