Description

Technical Field

[0001] The utility model relates to the field of engineering surveying, in particular to an anti-movement leveling point mark. Background Art

[0002] A level mark, also known as a level point or elevation control point, is a standard mark used in surveying and engineering to indicate the elevation of a specific location. This mark is usually permanently set on the ground or on a building to facilitate elevation measurement and topographic map production.

[0003] Existing level point marks are usually directly inserted into a drilled hole on the ground, and then concrete is injected into the drilled hole. The level point mark is fixed by the concrete solidification. However, while waiting for the concrete to solidify, the level point mark may move or tilt, resulting in deviations in the measurement results, which is inconvenient.

[0004] Therefore, it is necessary to design an anti-movement leveling point marker that can prevent the device from moving or tilting during the concrete curing process, avoid deviations in the measurement results, and ensure the accuracy of the measurement results. Utility Model Content

[0005] In order to overcome the disadvantage of existing level point marks that, while waiting for concrete to solidify, the level point marks may move or tilt, resulting in deviations in measurement results, which is quite inconvenient, the utility model provides an anti-movement level point mark that can prevent the device from moving or tilting during the concrete solidification process, avoid deviations in measurement results, and ensure the accuracy of measurement results.

[0006] A level point marker that prevents movement includes a sleeve, a positioning assembly, a benchmark, a connecting block, a clamping block, a cap and a marking ball. The upper part of the sleeve is provided with a positioning assembly, the connecting block is placed inside the sleeve, the upper side of the connecting block is connected to the benchmark, the upper part of the benchmark is connected to the clamping block, the upper side of the benchmark is connected to the cap, and the upper middle part of the cap is connected to the marking ball.

[0007] In a preferred embodiment of the utility model, the locking assembly includes a sleeve shell, a spring and a locking block. The outer side of the upper part of the sleeve is connected to the sleeve shell, and a plurality of locking blocks are slidably connected to the sleeve shell. The locking blocks are all connected to the sleeve shell by springs.

[0008] In a preferred embodiment of the present invention, the positioning blocks are all wedge-shaped.

[0009] In a preferred embodiment of the present invention, the diameter of the connecting block is smaller than that of the sleeve.

[0010] In a preferred embodiment of the present invention, a connecting plate is also included, and a plurality of connecting plates are connected to the outer side of the sleeve.

[0011] In a preferred embodiment of the present invention, the connecting plates are all arc-shaped.

[0012] The beneficial effects of the utility model are as follows: the utility model inserts the sleeve into the drill hole so that the connecting plate contacts the hole wall, and then pours concrete into the drill hole. After the concrete solidifies, the benchmark is inserted into the sleeve to drive the positioning block to move outward. When the benchmark continues to move downward, it drives the positioning block to move and reset, thereby preventing the device from moving or tilting during the concrete solidification process, avoiding deviations in the measurement results, and ensuring the accuracy of the measurement results. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.

[0014] Figure 2 It is a schematic cross-sectional view of the three-dimensional structure of the utility model.

[0015] Among them, the above-mentioned drawings include the following figure marks: 1_sleeve, 2_connecting plate, 3_housing, 4_spring, 5_block, 6_bar, 7_connecting block, 8_block, 9_cap, 10_marking ball. DETAILED DESCRIPTION

[0016] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0017] A level point marker that is resistant to movement, such as Figure 1 and Figure 2 As shown, it includes a sleeve 1, a connecting plate 2, a positioning assembly, a benchmark rod 6, a connecting block 7, a clamping block 8, a cap 9 and a marking ball 10. Twenty-five connecting plates 2 are connected to the outside of the sleeve 1. The connecting plates 2 are all arc-shaped. A positioning assembly is provided on the upper part of the sleeve 1. A connecting block 7 is placed inside the sleeve 1. The diameter of the connecting block 7 is smaller than that of the sleeve 1, so that it can fit easily with the inside of the sleeve 1. The upper side of the connecting block 7 is connected to the benchmark rod 6. The upper part of the benchmark rod 6 is connected to the clamping block 8. The upper side of the benchmark rod 6 is connected to the cap 9. The upper side of the cap 9 is connected to the marking ball 10.

[0018] like Figure 2 As shown, the locking assembly includes a sleeve shell 3, a spring 4 and a locking block 5. The sleeve shell 3 is connected to the outer side of the upper part of the sleeve 1. Six locking blocks 5 are slidably connected to the sleeve shell 3. The locking blocks 5 are all wedge-shaped, and springs 4 are connected between the locking blocks 5 and the sleeve shell 3.

[0019] When using the device, first insert the sleeve 1 into the drilled hole on the ground, then insert the sleeve 1 into the drilled hole so that the connecting plate 2 contacts the hole wall, then pour concrete into the drilled hole, wait for the concrete to solidify, insert the benchmark 6 into the sleeve 1, so that the connecting block 7 moves downward, so that the clamping block 8 contacts the extrusion clamping block 5, drives the clamping block 5 to move outward on the sleeve shell 3, and the spring 4 is squeezed and contracted. When the benchmark 6 continues to move downward, the spring 4 recovers, drives the clamping block 5 to move and reset, so that the clamping block 5 contacts the upper side of the clamping block 8, and the clamping block 8 is limited by the clamping block 5. The connecting block 7 contacts the bottom of the sleeve 1, so that the cap 9 contacts the ground, and is marked by the marking ball 10, thereby preventing the device from moving or tilting during the concrete solidification process, avoiding deviations in the measurement results, and ensuring the accuracy of the measurement results.

[0020] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
