Length measuring scale for heavy-duty commercial vehicle

Abstract

The utility model relates to a length measuring scale for a heavy-duty commercial vehicle, and solves the problems that a fixed length measuring scale cannot be aligned with a measuring basis, the measurement operation is inconvenient, the measurement cannot be carried out, or the size error is large. Comprising a measuring jaw, a movable measuring jaw, a main measuring scale, an auxiliary measuring scale and a locking bolt, the auxiliary measuring scale and the main measuring scale form a telescopic structure through the diameter change of a rod body, the measuring jaw is fixedly connected with the tail end of the main measuring scale, the movable measuring jaw is in clearance fit with the main measuring scale and the auxiliary measuring scale, and the top end of the auxiliary measuring scale is provided with a limiting structure. And the locking bolt is arranged on the movable measuring jaw. The measuring tool is not easy to deform during measurement and is convenient to measure.

Description

Technical Field

[0001] The utility model relates to a measuring tool, in particular to a length measuring ruler used for heavy commercial vehicles. Background Art

[0002] At present, when measuring the chassis height, tire diameter, width and other dimensions of ordinary commercial vehicles, due to the high height of the chassis and superstructure, and the inconvenience in measuring the parts themselves or their assembly positions, designers use tape measures, but there are problems such as the tape measure being soft and unable to be aligned and fixed with the measurement reference, resulting in large dimensional measurement errors. Utility Model Content

[0003] The utility model aims to design a length measuring ruler which is not easily deformed during measurement and solves the problems of being unable to align and fix with a measurement reference, causing inconvenient measurement operation, inability to measure or large dimensional errors.

[0004] The utility model is realized by the following technical solutions:

[0005] A length measuring ruler for heavy commercial vehicles includes a measuring jaw 1, a movable measuring jaw 2, a main measuring ruler 3, an auxiliary measuring ruler 4, and a locking bolt 5. The auxiliary measuring ruler 4 forms a telescopic structure with the main measuring ruler 3 by changing the diameter of the rod body. The measuring jaw 1 is fixedly connected to the end of the main measuring ruler 3, the movable measuring jaw 2 is fitted with the main measuring ruler 3 and the auxiliary measuring ruler 4 through clearance, a limiting structure is provided at the top of the auxiliary measuring ruler 4, and the locking bolt 5 is installed on the movable measuring jaw 2.

[0006] The measuring jaws 1 are fixedly connected to the main measuring ruler 3 via a threaded connection.

[0007] The utility model is not easily deformed during measurement and is convenient for measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic structural diagram of the utility model. DETAILED DESCRIPTION

[0009] like Figure 1 As shown, the measuring ruler includes a measuring jaw 1, a movable measuring jaw 2, a main measuring ruler 3, an auxiliary measuring ruler 4, and a locking bolt 5.

[0010] The auxiliary measuring scale 4 forms a retractable structure with the main measuring scale 3 by changing the diameter of the rod body. The measuring claw 1 is fixedly connected to the end of the main measuring scale 3 by a threaded connection. The movable measuring claw 2 is matched with the main measuring scale 3 and the auxiliary measuring scale 4 through clearance. A limiting structure is provided at the top of the auxiliary measuring scale 4 to prevent the movable measuring claw 2 from slipping. The locking bolt 5 is installed on the movable measuring claw 2, which can fasten the movable measuring claw 2 to the main measuring scale 3 and the auxiliary measuring scale 4.

[0011] The use process of the measuring ruler of the utility model is as follows:

[0012] The main and auxiliary measuring rulers 3 and 4 are graduated. The movable jaws 2 slide across the main ruler 3 to measure dimensions. The movable jaws 2 are secured with locking bolts 5 to read the dimensions. If the main ruler 3 is insufficient, the retractable auxiliary ruler 4 can be extended to complete the measurement.

Claims
