At present, in order to measure the gap between the parts on the vehicle, a gap ruler is usually inserted into the gap to be measured, when the gap ruler is pulled to feel resistance slightly, the scale on the gap ruler aligned at the edge of the gap to be measured is read, and the reading is the gap value to be measured.

However, the clearance gauge must be kept in the clearance to be measured and still when reading. The reason for this is that if the position of the gap gauge changes, the scale of the gap gauge aligned at the edge of the gap to be measured will also change, thus increasing the restriction on the environmental conditions at the time of reading. For example, when the gap to be measured is located in a narrow space or in a position exceeding the height range, the edge of the gap to be measured cannot be viewed horizontally during reading, so that the scale of the gap ruler aligned with the edge cannot be read accurately, and the gap measurement value has a large error.

Therefore, there is a need for a gap measuring tool that improves measurement accuracy.

FIG. 1 is a schematic view of a gap measuring tool according to an embodiment of the present application; fig. 2 is a schematic structural view of the gap measuring tool in the measuring state in the embodiment shown in fig. 1.

Referring to fig. 1-2, a gap measuring tool provided in an embodiment of the present application includes a scale 10 and a sliding mechanism 20. The scale 10 is provided with scales along the lengthwise extending direction thereof, the sliding mechanism 20 is connected with the scale 10 in a sliding manner, the sliding mechanism 20 is provided with mark lines 21 corresponding to the scales, and one end of the sliding mechanism 20 is provided with a first tip 22 used for extending into the gap.

In the gap measuring tool, the scale 10 is provided with a scale, so that the distance by which the slide mechanism 20 slides with respect to the scale 10 can be displayed by the scale. By providing a first tip 22 at one end of the sliding mechanism 20 for extending into the gap to be measured. Since the first pointed end 22 has a certain shape, the length and width dimensions of the first pointed end 22 can be determined, and therefore, when the two opposite sides of the first pointed end 22 along the width direction simultaneously contact the side walls of the gap to be measured, the length of the first pointed end 22 extending into the gap to be measured can be correspondingly determined, and the length can be represented by the distance that the sliding mechanism 20 slides on the scale 10, that is, the distance that the mark line 21 moves on the scale of the scale 10. In this way, in the actual measurement process, the scale indicated by the mark line 21 when the first tip 22 is flush with the edge of the gap to be measured and the scale indicated by the mark line 21 when the first tip 22 is in contact with the side walls of the gap to be measured opposite to each other are recorded, respectively, and the size of the gap to be measured can be obtained. Because reading the scale is carried out through the scale 10, need not to make the sight look at the edge of the gap that awaits measuring during the reading, and can fix slide mechanism 20 relative scale 10 when the reading, take out the first pointed end 22 and await measuring the reading behind the gap to improve the clearance measuring precision, and make the reading more convenient.

It should be noted that, in the actual measurement process, as shown in fig. 2, when the first tip 22 is inserted into the gap to be measured, the length direction of the first tip 22 is parallel to the depth direction of the gap to be measured. The width direction of the first pointed end 22 is perpendicular to the length direction of the first pointed end 22.

It will be appreciated that the length direction of the first tip 22 is parallel to the lengthwise extension direction of the scale 10, so that when the slide mechanism 20 is moved in the length direction of the first tip 22, i.e. during the time when the first tip 22 extends into the gap to be measured, the direction of movement of the slide mechanism 20 is parallel to the lengthwise extension direction of the scale 10. In this way, when the slide mechanism 20 slides relative to the scale 10, the mark lines 21 provided on the slide mechanism 20 can correspond to different scales on the scale 10.

In some embodiments, as shown in FIG. 2, the marking line 21 is disposed at an end of the sliding mechanism 20 away from the first tip 22 to increase a distance between the marking line 21 and the measuring head 25, facilitate insertion of the measuring head 25 into a gap to be measured, and facilitate reading of the scale by the position of the marking line 21.

In order to adapt the gap measuring tool to more usage scenarios, in some embodiments, the sliding mechanism 20 includes a slider 23, an adjusting portion 24 and a measuring head 25, the sliding mechanism 20 is slidably connected to the scale 10 through the slider 23, the measuring head 25 is used for extending into the gap to be measured, and the adjusting portion 24 is respectively connected to the slider 23 and the measuring head 25 to adjust the distance between the measuring head 25 and the slider 23. Specifically, the slider 23 is slidably connected to the scale 10, the marking line 21 is disposed on the slider 23, one end of the adjusting portion 24 is connected to the slider 23, one end of the measuring head 25 is slidably connected to the adjusting portion 24, and the other end of the measuring head 25 is provided with the first tip 22. In this way, by arranging the measuring head 25 to be slidably connected to the adjusting part 24 to change the distance between the measuring head 25 and the scale 10, the distance between the first tip 22 and the scale 10 is changed, so that the gap measuring tool can be applied to more usage scenarios. For example, when the space above the gap to be measured is limited, the measuring head 25 is positioned above the gap to be measured by sliding the measuring head 25 away from the scale 10, and the scale 10 is positioned in a larger space for easy operation and reading.

In one embodiment, as shown in fig. 1, one end of the slider 23 in the longitudinal extending direction is provided with a marking line 21, and the other end is connected to one end of the adjusting portion 24.

In some embodiments, as shown in fig. 1, the sliding block 23 is provided with a first threaded hole penetrating through the sliding block 23 along a direction perpendicular to the longitudinal extension direction of the scale 10, and the gap measuring tool further includes a first limiting member 30, and the first limiting member 30 is in threaded connection with the first threaded hole, so that the first limiting member 30 can abut against the scale 10. Thus, by providing the first threaded hole and the first limiting member 30, after the first limiting member 30 is screwed into the first threaded hole, the first limiting member 30 can abut against the scale 10 and generate pressure on the scale 10, and a friction force caused by the pressure can prevent relative movement between the first limiting member 30 and the scale 10, so that the slider 23 is fixed relative to the scale 10. In the actual use process, when the first tip 22 is aligned to the edge of the gap to be measured and the first tip 22 is tightly attached to the side wall of the gap to be measured (see fig. 2), the first position-limiting members 30 can be respectively screwed down to fix the slider 23 and the scale 10 when the scales are read twice, so that the error in reading is avoided, and the reading can be performed when the first tip 22 is taken out from the gap to be measured without manually fixing the slider 23.

Alternatively, as shown in fig. 2, the longitudinal extension direction of the adjustment part 24 is perpendicular to the longitudinal extension direction of the scale 10, so that when the measuring head 25 slides relative to the adjustment part 24, the movement direction of the measuring head 25 is perpendicular to the longitudinal extension direction of the scale 10, so that the measuring head 25 does not have displacement in the longitudinal extension direction of the scale 10, thereby not changing the distance between the first tip 22 and the marking line 21, and preventing measurement errors from being caused when adjusting the position of the measuring head 25.

In order to fix the measuring head 25 and the scale 10 after adjusting the distance therebetween, in some embodiments, as shown in fig. 2, the measuring head 25 is provided with a first through hole and a second threaded hole communicating with the first through hole, and the adjusting portion 24 passes through the first through hole. The clearance measuring tool further includes a second limiting member 40, and the second limiting member 40 is in threaded connection with the second threaded hole, so that the second limiting member can abut against the adjusting portion 24. Thus, by providing the first through hole, the measuring head 25 is made to slide in the first through hole. By providing the second threaded hole and the second limiting member 40, the second limiting member 40 can be inserted into the second threaded hole to abut against the adjusting portion 24, and by screwing the second limiting member 40 into the second threaded hole, the pressure of the second limiting member 40 on the adjusting portion 24 is increased, so that the friction force between the two is increased, and the measuring head 25 is fixed relative to the adjusting portion 24. In the actual use process, the distance between the measuring head 25 and the scale 10 is to be adjusted, the first tip 22 is aligned with the gap to be measured, and when the scale 10 is located at a position convenient for placing and reading, the second limiting member 40 is screwed down to fixedly connect the measuring head 25 and the adjusting portion 24.

In particular, the first through hole is provided at the end of the measuring head 25 opposite to the first tip 22.

More specifically, the axial direction of the first through hole is perpendicular to the longitudinal extension direction of the measuring head 25, and the axial direction of the second threaded hole is perpendicular to the axial direction of the first through hole.

In some embodiments, the sliding mechanism 20 has a first surface 220 and a second surface 222 that intersect, the first surface 220 and the second surface 222 sandwiching the first tip 22. In this manner, by providing the first surface 220 and the second surface 222, the dimensions of the first tip 22 in the width direction and the length direction are easily determined, and the width direction and the length direction of the first tip 22 are in a proportional relationship to further facilitate scale setting. In actual use, as shown in fig. 2, the first surface 220 and the second surface 222 are respectively used for contacting two opposite side walls of the gap to be measured so as to determine the distance between the two side walls, namely, the dimension value of the gap to be measured.

Further, as shown in fig. 1 and 2, the first surface 220 is parallel to the longitudinal extension direction of the scale 10, and the included angle between the first surface 220 and the second surface 222 is 45 degrees. In this way, by arranging the first surface 220 parallel to the lengthwise extension direction of the scale 10, the length of the first tip 22 extending into the gap to be measured is equal to the length of the first surface 220 extending into the gap to be measured. By setting the included angle between the first surface 220 and the second surface 222 to be 45 degrees, when the first surface 220 and the second surface 222 are in contact with two side walls opposite to the gap to be measured, the length of the first surface 220 extending into the gap to be measured is equal to the size of the gap to be measured, so that the setting and reading of the scales on the scale 10 are facilitated. In the actual use process, when the intersection of the first surface 220 and the second surface 222 is flush with the edge of the gap to be measured, the scale indicated by the mark line 21 is recorded as an initial scale, the first tip 22 extends into the gap to be measured, and when the first surface 220 and the second surface 222 are both tightly attached to the side wall of the gap to be measured, the scale indicated by the mark line 21 at this time is recorded as an end scale. And calculating the difference between the ending scale and the initial scale, wherein the difference is the size value of the gap to be measured.

In other embodiments, the included angle between the first surface 220 and the second surface 222 may be other angles, as long as the scale is configured to correspond to the first surface, and is not limited herein.

It will be appreciated that the accuracy and range of the scale on the scale 10 can be set according to the requirements of the application.

In one embodiment, as shown in fig. 1 and 2, the scale on the scale 10 has an accuracy of 1 mm and a measuring range of 120 mm.

In order to facilitate fixing the scale 10 relative to the gap to be measured during the measurement, in some embodiments, as shown in fig. 2, the gap measuring tool further includes a base 50, the base 50 is connected to an end of the scale 10 close to the first tip 22, and an end of the base 50 far from the scale 10 has a bottom surface perpendicular to a longitudinal extension direction of the scale 10. In this way, by providing the base 50 to support the scale 10, the scale 10 is connected to a plane perpendicular to the depth direction of the gap to be measured through the bottom surface. In the actual use process, the scale 10 is placed on a plane meeting the above conditions, and only the positions of the slide block 23 and the measuring head 25 need to be respectively adjusted during measurement, so that the operation is simple and convenient.

To facilitate the calculation of the difference between the end scale and the initial scale, in some embodiments, the scale 10 is provided with 0 scale lines, and the mark lines 21 indicate 0 scale lines (not shown) when the first tip 22 is flush with the bottom surface. It should be noted that this embodiment is suitable for the case where the bottom surface is flush with the edge of the gap to be measured, and by setting the 0-graduation mark, when the first tip 22 is flush with the bottom surface, the marking line 21 indicates the 0-graduation mark, and at this time, the first tip 22 is also flush with the edge of the gap to be measured, that is, the 0-graduation mark is the initial graduation. Therefore, when the first tip 22 is inserted to be closely attached to the gap to be measured, the end scale indicated by the mark line 21, that is, the size value of the gap to be measured, is directly read, thereby reducing the step of recording the initial scale.

Further, as shown in fig. 2, the clearance measuring tool further includes a limiting block 60, the limiting block 60 protrudes from the ruler 10, the limiting block 60 protrudes from one end of the ruler 10 having 0 scale mark, as shown in fig. 1, when the mark line 21 indicates 0 scale mark, the limiting block 60 abuts against the sliding mechanism 20. Through setting up stopper 60, make slide mechanism 20 move to with stopper 60 butt when, mark line 21 instructs 0 scale mark to be convenient for

make mark line

21 and 0 scale mark aim at, and make measurement accuracy further improve.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
