Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the utility model. In the present utility model, unless otherwise indicated, terms of orientation such as "upper" and "lower" and the like are used to generally refer to the upper and lower directions of the device in actual use or operation, and particularly to the directions of the drawings in the drawings.

Referring to fig. 1, an embodiment of the present utility model provides a novel height gauge, which mainly includes a base 1, a measuring scale 2, a slider 3, and a measuring arm 4; the measuring ruler 2 is vertically arranged on the base 1, the sliding block 3 is movably arranged on the measuring ruler 2, and can move up and down along the measuring ruler 2 under the drive of a linear transmission structure such as a rack, a screw rod and the like; the measuring arm 4 is mounted on the slider 3 and can move up and down with the slider 3 to make a height measurement.

The slider 3 is provided with a measuring arm support 5 for mounting the measuring arm 4, and specifically, as shown in fig. 2, the measuring arm support 5 may be fixedly connected to the slider 3 by a fastener 6 such as a screw. In order to further ensure the stability of the measuring arm support 5 and avoid the influence of the up-and-down shaking of the measuring arm support 5 on the measuring result, as shown in fig. 3, in this embodiment, a positioning groove 7 matched with the measuring arm support 5 is provided on the slider 3, and the measuring arm support 5 is embedded into the positioning groove 7 and fixedly connected with the slider 3 through a fastener 6; meanwhile, the measuring arm support 5 and the sliding block 3 can be adhered and fixed through UHU and other high-strength glue, so that the connection between the two is enhanced.

As shown in fig. 2, the measuring arm bracket 5 is provided with a chute 8 extending along the horizontal direction, and the measuring arm 4 is slidably inserted into the chute 8, so that the measuring arm 4 can move transversely along the chute 8 in the horizontal direction, and thus extends into a detection point which is difficult to measure at ordinary times for measurement; the measuring arm 4 is preferably made of a high-hardness material such as stainless steel, so that good stability and measuring accuracy can be ensured under the use condition of the maximum extension length. Further, in this embodiment, the hard alloy measuring head 9 with a tip is arranged at the measuring end of the measuring arm 4, so that the measuring arm 4 can also mark a scribe line while measuring the height, and the hard alloy measuring head 9 can effectively reduce the abrasion caused by the scribe line and prolong the service life of the measuring head.

The measuring arm bracket 5 is further provided with a locking bolt 10 for limiting the sliding of the measuring arm 4, specifically, as shown in fig. 4, the measuring arm bracket 5 is provided with a threaded hole 11 in threaded fit with the locking bolt 10, and the inner end of the threaded hole 11 is communicated with the chute 8, so that the inner end of the locking bolt 10 can extend into the chute 8 to abut against the measuring arm 4, and the measuring arm 4 is locked and fixed. The locking bolt 10 is screwed outwards to release the locking and fixing of the measuring arm 4, so that the extension length of the measuring arm 4 can be adjusted according to actual measurement requirements; of course, different measuring arms 4 can be replaced according to different measuring requirements, for example, the measuring arm can be replaced by a special-shaped measuring arm shown in fig. 5, the measuring end of the special-shaped measuring arm extends along the horizontal direction after being bent downwards, and the measuring end can be attached to the horizontal plane of the base 1 for zero setting and used as a reference plane for measurement.

It can be understood that the mounting structure of the measuring arm support 5 and the measuring arm 4 can be directly applied to the existing digital display height ruler, and the digital display height ruler can accurately adjust the measuring position and display the measuring structure in real time. The principles and embodiments of the present utility model have been described herein with reference to specific examples, but the description of the above examples is only for aiding in the understanding of the technical solution of the present utility model and its core ideas; those of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
