[0002] In fields such as building engineering, road construction, and topographic surveying, leveling is a fundamental method for obtaining elevation data. Currently, commonly used leveling equipment typically consists of a level instrument and a leveling rod, and surveyors must manually read the data and adjust the position of the leveling rod to complete the measurement.

[0003] Traditional methods require manual and repeated movement of the leveling rod and reliance on visual estimation of distance, making it difficult to quickly and accurately place the leveling rod in the set position, thus affecting measurement efficiency. Furthermore, although some devices are equipped with a measuring tape for positioning, the measuring tape has a complex installation structure and lacks quick disassembly and positioning functions, resulting in time-consuming and laborious tape replacement.

[0004] Based on this, a portable leveling device is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

The positioning rod is provided on the inner wall of the mounting frame away from the docking rod. The sliding positioning cylinder is slidably provided on the positioning rod. One end of the second lead screw passes through the inner wall of the mounting frame and abuts against the side wall of the sliding positioning cylinder for rotational engagement. The other end of the second lead screw is connected to the rotary knob. The mounting frame is provided with a thread that engages with the second lead screw.

[0009] Preferably, the clamping mechanism includes a clamping seat, a push plate, a rotating block, and a first lead screw. The clamping seat is slidably engaged with the leveling rod. The push plate is slidably provided on the inner wall of the clamping seat. The other end of the first lead screw passes through the inner wall of the clamping seat and is rotatably engaged with the inner wall of the push plate. The other end of the first lead screw is provided with a rotating block.

[0010] Preferably, the measuring instrument is provided with a pull ring that engages with the pull block.

[0011] The advantages of this utility model compared to the prior art are:

[0012] 1. This utility model, through the cooperation of the clamping mechanism and the measuring tape, allows the surveyor to intuitively read the tape scale and quickly move the leveling rod to the preset position, reducing manual estimation time and significantly improving work efficiency.

Detailed Implementation

[0018] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-3A portable leveling measuring device includes a support frame 101, on which a measuring instrument 102 is mounted. A leveling rod 104 for use with the measuring instrument 102 is mounted next to it. The leveling rod 104 is clamped and fixed by a clamping mechanism 200. The clamping mechanism 200 is provided with a mounting frame 105. A support mechanism 400 for quick installation of a measuring tape 107 is provided inside the mounting frame 105.

[0020] The clamping mechanism 200 is used to limit and clamp the leveling rod 104, and the support mechanism 400 is used to limit and position the measuring tape 107, so as to facilitate the replacement and installation of the measuring tape 107.

[0021] Reference Figures 2-3 The support mechanism 400 includes a positioning cylinder 401 and a connecting rod 402. The positioning cylinder 401 is fixedly installed on the inner wall of the mounting frame 105. The positioning cylinder 401 is provided with a connecting rod 402 for the measuring tape 107 to pass through. The other end of the measuring tape 107 passes through the side wall of the mounting frame 105 and is connected to a pull block 106. The mounting frame 105 is provided with a positioning mechanism 300 for limiting the installation of the measuring tape 107.

[0022] The connecting rod 402 is used for the measuring tape 107 to pass through for initial positioning and limiting, and the positioning mechanism 300 is used to further fix the measuring tape 107.

[0023] Reference Figures 2-3 The positioning mechanism 300 includes a rotary knob 301, a positioning rod 302, a sliding positioning cylinder 303, and a second lead screw 304. The positioning rod 302 is provided on the inner wall of the mounting frame 105 away from the docking rod 402. The sliding positioning cylinder 303 is slidably provided on the positioning rod 302. One end of the second lead screw 304 passes through the inner wall of the mounting frame 105 and abuts against the side wall of the sliding positioning cylinder 303 for rotational engagement. The other end of the second lead screw 304 is connected to the rotary knob 301. The mounting frame 105 is provided with a thread that engages with the second lead screw 304.

[0024] Rotating this knob 301 can drive the second lead screw 304 to rotate, enabling the second lead screw 304 to push against the sliding positioning cylinder 303 to further limit and position the measuring tape 107.

[0025] Reference Figures 2-3 The clamping mechanism 200 includes a clamping seat 201, a push plate 202, a rotating block 203, and a first lead screw 204. The clamping seat 201 is slidably engaged with the leveling rod 104. The push plate 202 is slidably provided on the inner wall of the clamping seat 201. The other end of the first lead screw 204 passes through the inner wall of the clamping seat 201 and is rotatably engaged with the inner wall of the push plate 202. The other end of the first lead screw 204 is provided with a rotating block 203.

[0026] Rotating this rotating block 203 drives the first lead screw 204 to rotate, and the first lead screw 204 pushes the leveling rod 104 to a limit position by the push plate 202, so as to realize the rapid installation of the leveling rod 104.

[0027] Reference Figure 1 The measuring instrument 102 is provided with a pull ring 103 that is connected to the pull block 106.

[0028] Working principle: Rotating the knob 301 drives the second lead screw 304 to rotate, allowing the second lead screw 304 to push against the sliding positioning cylinder 303 for further positioning and limiting of the measuring tape 107. The connecting rod 402 is used for the measuring tape 107 to pass through for initial positioning and limiting. After passing the measuring tape 107 through the connecting rod 402, rotating the knob 301 drives the second lead screw 304 to rotate, allowing the second lead screw 304 to push against the sliding positioning cylinder 303 for further positioning and limiting of the measuring tape 107. The pull block 106 is hung on the pull ring 103. The worker moves the leveling rod 104 and observes the scale on the measuring tape 107 until it reaches the originally set designated position. The leveling rod 104 is placed on the ground to make it vertical, which facilitates the worker to quickly place it to the designated position. At the same time, it facilitates the quick installation and disassembly of the measuring tape 107, improving work efficiency.

[0029] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
