Embodiment 1

[0040] Please refer to Figure 1 to Figure 4 , figure 1 A schematic structural view of the first auxiliary device in the tape measure auxiliary measuring tool provided by Embodiment 1 of the present invention; figure 2 for figure 1 The front view of the first assistive device in ; image 3 for figure 1 Side view of the first assistive device in ; Figure 4 for figure 1 Cutaway view of the first assistive device in . The specific embodiment of the present invention proposes a tape measure auxiliary measuring tool, which is characterized in that it includes a first auxiliary device 1; the first auxiliary device 1 is provided with a fixing plate 2 for fixing the 0 scale end of the tape measure, and the fixing plate 2 There is a first groove 3 for being passed through by the tape measure;

[0041] The side of the fixed plate 2 is provided with a mounting plate 4, and the side of the mounting plate 4 away from the fixed plate 2 is provided with a first positioning block 5, ...

Embodiment 2

[0048] Please refer to Figure 5 to Figure 8 , Figure 5 A schematic structural view of the second auxiliary device in the tape measure auxiliary measuring tool provided by Embodiment 2 of the present invention; Image 6 for Figure 5 The front view of the second assistive device in ; Figure 7 for Figure 5 Side view of the second assistive device in ; Figure 8 for Figure 5The cross-sectional view of the second auxiliary device in; this embodiment further includes a second auxiliary device 7 on the basis of embodiment 1, and the second auxiliary device 7 is provided with a fixed head 8, and the fixed head 8 is There is a second groove 12 for being passed by the tape measure, the fixed head 8 is provided with a reading hole 13, and the axis direction of the reading hole 13 is perpendicular to the side of the second groove 12; specific implementation , the fixing head 8 is a cylinder with a rectangular cross section.

[0049] One end of the fixed head 8 is provided wit...

Embodiment 3

[0054] Please refer to Figure 9 to Figure 12 , Figure 9 A schematic structural view of the second auxiliary device in the tape measure auxiliary measuring tool provided by Embodiment 3 of the present invention; Figure 10 for Figure 9 The front view of the second assistive device in ; Figure 11 for Figure 9 Side view of the second assistive device in ; Figure 12 for Figure 9 Cutaway view of the second assistive device in . . In this embodiment, the only difference from Embodiment 2 is that the second positioning hole 10 is changed from a stepped hole with a circular cross section to a stepped hole with a regular hexagonal cross section, so as to adapt to different types of nuts. In this way, when a bolt is installed in the hole, it can be positioned directly by fitting the hexagonal stepped hole on the nut.

Abstract

The invention discloses a subsidiary measuring tool for a tape, wherein the subsidiary measuring tool comprises a first subsidiary tool; the first subsidiary tool is provided with a fixing plate for fixing the 0 scale end of the tape, and the fixing plate is provided with a first groove through which the tape can pass; a side surface of the fixing plate is provided with a mounting plate, one side,which is far away from the fixing plate, of the mounting plate is provided with a first positioning block, and the center line of the first positioning block is arranged on a side surface of the fixing plate; one side, which is far away from the fixing plate, of the first positioning block is provided with a first positioning hole or a first positioning shaft which is concentric with the first positioning block. The subsidiary measuring tool can be used for determining the position of the center line of a hole during length measurement, and the measuring accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automobile measuring tools, in particular to a tape measure auxiliary measuring tool. Background technique [0002] Truck frames are generally long, and there are many holes distributed on the longitudinal beams and beams. These holes are used to install the engine, battery bracket, fuel tank, urea tank and other assemblies, or for the connection of the frame itself. Basically divided into bolt connection and rivet connection. [0003] In the trial production stage of the whole vehicle, it is necessary to measure the hole distance of the actual vehicle frequently for inspection or verification. However, due to the inconvenient positioning of the hole position or the installation of nuts or rivets, the center of the hole cannot be accurately positioned, resulting in inaccurate measurement of the hole distance. [0004] How to accurately measure the hole distance is one of the important problems to be sol...
