Description

Technical Field

[0001] The utility model relates to the technical field of building measurement, in particular to an auxiliary measurement mechanism of an electronic level. Background Art

[0002] The electronic level, also known as the digital level, consists of a base, a level, a single telescope and a data processing system. The electronic level is based on the automatic leveling level, with a spectrometer and a detector added to the telescope optical path.

[0003] An existing patent (publication number CN214276897U) and an electronic level for municipal engineering measurement, the patented bracket supports the bearing sleeve. Before using the device, the support plate can move up and down with the movable sleeve, thereby driving the electronic level body to move up and down, making it convenient to adjust the height of the electronic level body. After loosening the lever, the electronic level body can be manually rotated while observing the scale, making it convenient to accurately adjust the direction of the electronic level body. After determining the direction of the electronic level body, the lever can be tightened to fix the electronic level body. However, the working condition of the electronic level is relative to the load, and the points of the triangular support often have different heights, which causes the electronic level to be not on the same horizontal plane, which also leads to inaccurate measurement.

[0004] Therefore, we propose an auxiliary measurement mechanism for an electronic level, which is helpful for ensuring the horizontality of the electronic level when facing complex road surfaces and is helpful for ensuring the horizontality of the electronic level when the three-point support is not at the same height.

The other end of the push rod is slidably nested in the extension rod. The push rod and the extension rod are rotated and fixed together by the locking screw.

[0009] Further: the movable joint is composed of two plate-like components and a bolt, two groups of plate-like components are fixed to the outer wall of the slider, the end of the push rod is placed between the two groups of plate-like components, and the bolt passes through the two groups of plate-like components and the push rod.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] 1. The auxiliary measuring mechanism of the electronic level of the utility model is provided with a support column, a triangular shell, a rack, a block, a positioning screw and a slider. The support column is unfolded by sliding the triangular shell and fixed by the screw, so that the support column is supported on the ground, and then the length of the telescopic support structure is adjusted according to the actual terrain. After the length of the telescopic support structure is fixed, the height of the slider on the slide rod is adjusted, and the positioning screw is rotated to make the block engage with the rack, and then the slider is fixed.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solution of the utility model in conjunction with the drawings in the utility model. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the structures involved in the utility model are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-4 The utility model provides a technical solution: an electronic level auxiliary measurement mechanism, including a triangular shell 1, a support column 2 is slidably embedded at the bottom end of the triangular shell 1, the triangular shell 1 and the support column 2 are tightly fixed by rotating a screw, and the height of the entire device can be adjusted by adjusting the length of the extended support column 2, a fixed plate 3 is fixed on the top of the triangular shell 1, and a groove body 5 is opened on the outer side wall of the triangular shell 1, a sliding rod 51 is vertically arranged inside the groove body 5, and a sliding block 52 is slidably installed on the sliding rod 51. The outer wall of the block 52 is connected to the telescopic support structure 4 through a movable joint 55. The telescopic support structure 4 includes a push rod 41, an extension rod 42 and a locking screw 43. The end of the push rod 41 is connected to the slider 52 through the movable joint 55. The other end of the push rod 41 is slidably embedded in the extension rod 42. The push rod 41 and the extension rod 42 are rotated and fixed by the locking screw 43. The extension rod 42 under the push rod 41 is pulled to expand. The expansion length of the two is adjusted according to actual needs, and then they are fixed by the locking screw 43.

[0024] The support column 2 under the sliding triangular shell 1 is unfolded and fixed by screws, and the support column 2 is placed on a flat ground. Since the support column 2 has a small foothold area, when the ground is flat, the fixed plate 3 is relatively horizontal. After the fixed plate 3 is determined to be in a horizontal state, the lengths of the three sets of telescopic support structures 4 are adjusted respectively, so that when the three-point support is at different heights, the fixed plate 3 is still in a horizontal state, which is conducive to ensuring the horizontality of the sub-level when the three-point support is not at the same height;

[0025] The inner wall of the groove body 5 is provided with a rack 54, and a positioning screw 53 is screwed on one side of the slider 52. The end of the positioning screw 53 is connected to a clamping block 531 through a bearing. The clamping block 531 is clamped with the rack 54. The clamping block 531 is in a mountain shape and has three groups of clamping points. The clamping points of the clamping block 531 are clamped with the gaps of the rack 54.

[0026] The support column 2 is unfolded by sliding the triangular shell 1 and fixed by a screw, so that the support column 2 is supported on the ground, and then the length of the telescopic support structure 4 is adjusted according to the actual terrain, and the extension rod 42 under the top rod 41 is pulled to unfold, and the unfolded length of the two is adjusted according to actual needs, and then the locking screw 43 is used to tighten and fix it. After the length of the telescopic support structure 4 is fixed, the height of the slider 52 on the slide rod 51 is adjusted, and the positioning screw 53 is turned to make the block 531 engage with the rack 54, and then the slider 52 is fixed. By using sliders 52 of different heights and telescopic support structures 4 of different lengths, complex road conditions can be faced, which is beneficial to ensure the levelness of the electronic level when facing complex roads.

[0027] The movable joint 55 is composed of two plate-like parts and a bolt. Two groups of plate-like parts are fixed to the outer wall of the slider 52. The end of the push rod 41 is placed between the two groups of plate-like parts, and the bolt penetrates the two groups of plate-like parts and the push rod 41. This structure is common in the mechanical field. A rotation effect is formed by loosening the bolt, and a fixing effect is formed by tightening the bolt.

[0028] A limiting component may be provided for the movable joint 55 to limit the rotation angle of the push rod 41 and further ensure the stability of the support.

[0029] A hole for fixing the electronic level is provided on the top of the fixing plate 3, and the electronic level is fixed corresponding to the hole.

[0030] Working principle: When there is an obvious height difference in the measured road surface;

[0031] The support column 2 is unfolded by sliding the triangular shell 1 and fixed by screws, and the support column 2 is placed on a flat ground. Since the support column 2 has a small foothold area, when the ground is flat, the fixed plate 3 is relatively horizontal. After the fixed plate 3 is determined to be in a horizontal state, the lengths of the three groups of telescopic support structures 4 are adjusted respectively, and the extension rod 42 under the top rod 41 is pulled to unfold them. The unfolding lengths of the two are adjusted according to actual needs, and they are fixed tightly by the locking screw 43, so that when the three-point support is at different heights, the fixed plate 3 is still in a horizontal state, so that the levelness of the sub-level instrument is guaranteed when the three-point support is not at the same height;

[0032] When the road surface is uneven;

[0033] The support column 2 is unfolded by sliding the triangular shell 1 and fixed by a screw, so that the support column 2 is supported on the ground, and then the length of the telescopic support structure 4 is adjusted according to the actual terrain. After the length of the telescopic support structure 4 is fixed, the height of the slider 52 on the slide rod 51 is adjusted, and the positioning screw 53 is rotated to make the block 531 engage with the rack 54, thereby fixing the slider 52. By using sliders 52 of different heights and telescopic support structures 4 of different lengths, complex road conditions can be coped with.
