[0028] Please refer to Figures 1 to 7For the utility model one embodiment's engineering cost uses level gauge support, including support subassembly 10, and set up in support subassembly 10 for installing level gauge's fixed component 20;Support subassembly 10 includes installing in fixed component 20 on support table 11, and multiple telescopic support 12 of pivot mounting on support table 11;Telescopic support 12 includes installing on support table 11 on support portion 120, installing in the telescopic fixed sleeve 121 of support portion 120 the end away from support table 11, the lower support portion 122 for supporting of sleeve joint in telescopic fixed sleeve 121, and installing in telescopic fixed sleeve 121 for locking fastener 123 of lower support portion 122 is carried out;Fixed component 20 includes pivot mounting on support table 11 on angle adjustment seat 21, and installing in angle adjustment seat 21 for installing level gauge's fixed table 22;Angle adjustment seat 21 is set up and is installed groove 210 of penetrating from front to back, and fixed table 22 is installed in groove 210 on clamping.This embodiment, telescopic support 12 is three, and three telescopic support 12 circumferential array installs in support table 11 periphery.This embodiment, support portion 120 includes pivot mounting on support table 11 on rotating sleeve 124, installing on rotating sleeve 124 on support frame 125;Telescopic fixed sleeve 121 installs in support frame 125 the end away from rotating sleeve 124.This embodiment, level gauge body 50 includes equipment body 51, set up in equipment body 51 on measuring lens 52, set up in equipment body 51 on the side away from measuring lens 52 on display screen 53, installing in equipment body 51 on display screen 53 side on adjusting button 54.

[0029] The working principle of the level support for engineering cost is as follows: the lower support part 122 of the telescopic support part 12 can be telescoped in the telescopic fixing sleeve 121, based on the sliding friction principle, the lower support part 122 slides in the telescopic fixing sleeve 121, and the overall length of the telescopic support part 12 is changed; during the adjustment process, the height of the level is adjusted by controlling the length of the lower support part 122 to extend or retract, so as to adapt to different terrains and measurement requirements; the angle adjusting seat 21 in the fixing assembly 20 is rotatably installed on the support table 11, so that the angle adjusting seat 21 can flexibly rotate around the specific axis of the support table 11; the fixing table 22 is clamped and installed on the mounting groove 210 of the angle adjusting seat 21, the clamping structure utilizes the mutual constraint and friction force between objects, so that the fixing table 22 and the angle adjusting seat 21 are relatively fixed; the fastener 123 is installed on the telescopic fixing sleeve 121 and is used for locking the lower support part 122; when the fastener 123 is tightened, the fastener 123 will exert pressure on the lower support part 122, so that the friction force between the lower support part 122 and the telescopic fixing sleeve 121 is increased; when the friction force is large enough, the lower support part 122 is tightly fixed at the current position and cannot slide in the telescopic fixing sleeve 121 any more, so that the locking of the height of the level support is realized, and the height of the level is kept unchanged during the measurement process.

[0030] Compared with the prior art, the level support for engineering cost can better resist external forces from different directions, effectively prevents the level support from tilting or shaking during use, and further improves the overall stability and safety through the support assembly 10 and the fixing assembly 20; the upper support part 120 is provided with the rotating sleeve 124, so that the telescopic support part 12 can not only adjust the height through the telescoping of the lower support part 122, but also can rotate to a certain extent with the rotating sleeve 124 as the axis, which further increases the flexibility of angle adjustment of the level support; the telescoping operation of the lower support part 122 in the telescopic fixing sleeve 121 is more flexible and convenient based on the sliding friction principle, and the operator can more easily control the length of the lower support part 122 to extend or retract, so as to realize the rapid and accurate adjustment of the height of the level and improve the efficiency of the measurement work; the rotary connection of the angle adjusting seat 21 and the support table 11 and the clamping connection of the fixing table 22 and the angle adjusting seat 21 cooperate with the rotating function of the telescopic support part 12, so that the angle adjustment of the level in the horizontal and vertical directions is more rapid and convenient.

[0031] Please refer to Figure 1 and Figure 2, the engineering cost level instrument support further includes a telescopic assembly 30 installed on the support table 11, a plurality of connection stabilizing assemblies 40 with one end pivot installed on the upper support part 120 and the other end pivot installed on the free end of the telescopic assembly 30; the telescopic assembly 30 includes a telescopic fixing piece 31 with a pivot installed on the free end of each support assembly 10, and a telescopic piece 32 with one end installed on the telescopic fixing piece 31 and the other end installed on the support table 11. The connection stabilizing assembly 40 is connected to the upper support part 120 at one end and to the free end of the telescopic assembly 30 at the other end, which is equivalent to adding a diagonal support force on the basis of the original support structure; so that when the entire level instrument support is subjected to external force, the force can be more evenly dispersed to each component through these connection stabilizing assemblies 40, further enhancing the stability of the overall structure and reducing the possibility of shaking and deformation, especially in complex terrain or environments with external interference, which can better ensure the stability of the level instrument; the telescopic assembly 30 makes the level instrument support more flexible when dealing with different terrains; the telescopic assembly 30 and the connection stabilizing assembly 40 cooperate with the original telescopic support piece 12 and the fixing assembly 20 to achieve multi-angle coordinated adjustment; the operator can adjust the telescoping and rotation of different assemblies simultaneously or separately according to actual measurement needs, more accurately control the height, levelness and angle of the level instrument, improve the accuracy and efficiency of adjustment, reduce the number of repeated adjustments and save measurement time.

[0032] The telescopic part 32 comprises a telescopic outer tube 320 mounted on the support table 11, a telescopic inner tube 321 mounted at one end in the telescopic outer tube 320 and at the other end in the telescopic fixing part 31, and elastic lugs 322 provided on the telescopic inner tube 321, and a plurality of grooves 323 provided in the length direction of the telescopic outer tube 320 and matched with the elastic lugs 322. The telescopic outer tube 320 is provided with a plurality of grooves 323 matched with the elastic lugs 322, so that the telescopic inner tube 321 can have a plurality of fixed positions in the telescopic outer tube 320. When adjusting the height of the level instrument support, the elastic lugs 322 can be clamped into the grooves 323 at different positions to achieve accurate adjustment of different heights, meet the specific requirements of various different terrains and measurement scenarios for the height of the level instrument, and compared with the telescopic structure without a positioning device, the level instrument can be adjusted to the appropriate height more quickly and accurately. The clamping effect between the elastic lugs 322 and the grooves 323 can effectively prevent the telescopic inner tube 321 from accidentally sliding in the telescopic outer tube 320. During the use of the level instrument, even if subjected to certain external force vibration or shaking, the telescopic inner tube 321 can remain at the set position and will not change the height at will due to these external forces, thereby ensuring the stability of the height of the level instrument support and further ensuring the accuracy and reliability of the measurement results. After the elastic lugs 322 are clamped into the grooves 323, the contact area and friction between them are increased to some extent, so that the telescopic assembly 30 can better transmit and disperse the force when bearing the weight of the level instrument and possible lateral force and other external forces, reduce the possibility of structural loosening or damage caused by loose connection, and improve the structural strength and durability of the entire telescopic assembly 30 and the level instrument support.

[0033] Please refer to Figures 3 to 5The fixing table 22 is provided with a clamping cavity 211 between the mounting groove 210 and the fixing table 22, the fixing table 22 on the side away from the angle adjusting seat 21 is provided with a front and rear sliding track 220 communicated with the clamping cavity 211, and a protruding groove 221 communicated with the front and rear sliding track 220 is arranged. The width of the protruding groove 221 is greater than the width of the sliding track. The engineering cost level gauge support further comprises a level gauge body 50 and a sliding piece 60 arranged at the bottom of the level gauge body 50. The sliding piece 60 at the bottom of the level gauge body 50 can be directly and quickly slid into the front and rear sliding track 220 on the fixing table 22, and the installation is realized by cooperating with the clamping cavity 211, without the need for complex operation and alignment process, which can significantly improve the installation efficiency of the level gauge and save the preparation time of the measurement work. The width of the protruding groove 221 is greater than the width of the sliding track, which can provide a wider adjustment space when the sliding piece 60 enters the protruding groove 221 from the sliding track, facilitating the operator to fine-tune the position of the level gauge, ensuring the accurate installation of the level gauge at the required position, and improving the measurement accuracy. The cooperation of the clamping cavity 211 and the sliding piece 60 makes the connection between the level gauge and the fixing table 22 more closely, which limits the shaking of the level gauge in the horizontal direction. Even if the level gauge is subjected to slight external force or vibration during the measurement process, the level gauge can remain stable, ensuring the reliability of the measurement result. In cooperation with the rotation of the angle adjusting seat 21, the level gauge can not only rotate around the specific axis of the support table 11 after installation, but also realize the position adjustment in the front and rear directions by the sliding of the sliding piece 60 on the front and rear sliding track 220, so that the level gauge can be angle-adjusted in multiple directions, better adapting to different measurement scenes and terrain requirements, improving the use flexibility and applicability of the level gauge. The design of the sliding track and the protruding groove 221 provides convenience for the angle fine-tuning of the level gauge. The operator can accurately adjust the angle of the level gauge by slightly moving the position of the level gauge according to the actual measurement demand, ensuring that the measurement line of sight and the target object or the measurement plane maintain the best angle, and improving the measurement precision.

[0034] The sliding piece 60 comprises a sliding block 61 mounted at the bottom of the level body 50 and matched with the front and rear sliding tracks 220, and a protruding block 62 mounted at the bottom of the sliding block 61 and matched with the protruding groove 221; the width of the protruding block 62 is greater than the width of the front and rear sliding tracks 220, and the width of the protruding block 62 is less than the width of the protruding groove 221. The sliding block 61 is matched with the front and rear sliding tracks 220, which can provide accurate guidance for the installation of the level; during the installation, the operator can easily align the sliding block 61 with the sliding tracks, so that the level can be accurately installed on the fixed table 22 along the predetermined path, reducing the deviation and errors in the installation process and improving the accuracy and efficiency of the installation; the sliding block 61 slides along the front and rear sliding tracks 220, which can quickly reach the approximate installation position of the level, realizing coarse positioning; then fine adjustment is performed by the cooperation of the protruding block 62 and the protruding groove 221, which is a positioning method of coarse first and fine later, which helps to quickly install the level in the appropriate position and saves the installation time; the sliding block 61 is closely matched with the front and rear sliding tracks 220, which limits the relative displacement between the level and the fixed table 22 in the horizontal direction, so that the level can remain stable during the measurement and will not shake in the horizontal direction due to slight vibration or collision of the outside, thereby ensuring the accuracy and reliability of the measurement results; the width of the protruding block 62 is greater than the width of the front and rear sliding tracks 220 and less than the width of the protruding groove 221, when the sliding block 61 is on the sliding track, the protruding block 62 plays a certain limiting role, preventing the sliding block 61 from accidentally falling out from the side of the track; at the same time, the protruding block 62 also has a certain space for movement in the protruding groove 221, but it will not easily fall out of the protruding groove 221, further enhancing the stability and safety of the level after installation, and reducing the risk of accidental falling of the level.

[0035] The angle adjustment knob 215 and the fixed handrail 211 are arranged on both sides of the angle adjustment seat 21. The arrangement of the angle adjustment knob 215 enables the operator to finely adjust the angle of the level; by rotating the adjustment knob, the inclination angle of the level can be accurately changed according to the measurement requirements, ensuring that the measurement line of sight can be accurately aligned with the target, thereby improving the accuracy and precision of the measurement; whether it is for horizontal measurement or inclination measurement, the required angle change can be realized through the adjustment knob to meet the needs of different measurement scenarios; the fixed handrail 211 can play a role in auxiliary fixation when adjusting the angle; when the operator rotates the angle adjustment knob 215, the hand can hold the fixed handrail 211 at the same time, increasing the stability of the operation, preventing the level from shaking or shifting due to improper force or accidental collision, thereby ensuring the stability of the angle adjustment process, avoiding interference with the adjusted angle, and ensuring the accuracy of the measurement.

[0036] Please refer to Figure 1 , Figure 6 and Figure 7The leveling instrument support for engineering cost further comprises a moving assembly 70 installed on the telescopic fixing sleeve 121; the moving assembly 70 comprises a length adjusting piece 71 installed on the telescopic fixing sleeve 121 and a moving piece 72 installed on the length adjusting piece 71. The length adjusting piece 71 can flexibly adjust the length of the leveling instrument support under different terrain conditions; for example, when measuring in a mountainous or hilly terrain with large undulations, the leveling instrument can be kept at a suitable height and position by adjusting the length, so as to ensure that the measurement line of sight is not blocked and the measurement work can be smoothly carried out; different engineering projects can have different requirements for the position and height of the leveling instrument; the moving piece 72 is installed on the length adjusting piece 71 and can realize the horizontal movement and height fine adjustment of the leveling instrument within a certain range, can accurately aim at different positions of the measurement points, meets the requirements of various measurement scenes such as road construction and building foundation measurement, and improves the universality and adaptability of the leveling instrument support; the moving assembly 70 facilitates the operator to quickly adjust the position of the leveling instrument; during the measurement process, if the measurement angle or position needs to be changed, the leveling instrument can be quickly moved to a new measurement point by operating the length adjusting piece 71 and the moving piece 72, without the need to disassemble and install the support again, thereby saving a large amount of time and labor cost and improving the work efficiency.

[0037] The length adjusting member 71 comprises a fixed part 710 mounted on the telescopic fixing sleeve 121, a sliding part 711 sliding on the fixed part 710, and the moving member 72 is mounted on the sliding part 711 away from the telescopic fixing sleeve 121. The fixed part 710 is provided with elastic buckles 712, and the sliding part 711 is provided with positioning grooves 713 matched with the elastic buckles 712. In the embodiment, the elastic buckles 712 and the positioning grooves 713 are both multiple. The sliding part 711 can slide smoothly on the fixed part 710, and the operator can quickly change the overall length of the length adjusting member 71 according to the actual measurement needs, and then adjust the height and position of the level gauge. The level gauge can quickly adapt to different measurement scenes, such as measuring on uneven ground or different floors, and can quickly adjust the level gauge to the appropriate height, improving the work efficiency. The cooperation of the elastic buckles 712 and the positioning grooves 713 can realize accurate positioning. When the sliding part 711 slides to the appropriate position, the elastic buckles 712 will be clamped into the corresponding positioning grooves 713 to fix the sliding part 711, so as to ensure that the level gauge will not move accidentally during the measurement process and affect the measurement result. When it is needed to retract the sliding part 711 into the fixed part 710, the operator can push the sliding part 711 towards the fixed part 710, so that the elastic buckles 712 and the positioning grooves 713 are separated, and then the elastic buckles 712 away from the moving assembly 70 are fallen into the positioning grooves 713 away from the moving assembly 70, so as to realize the positioning of the sliding part 711. The operator can accurately control the position of the sliding part 711 according to the distribution of the positioning grooves 713, so as to realize the accurate adjustment of the height and position of the level gauge, and meet the requirements of high-precision measurement. The close cooperation of the elastic buckles 712 and the positioning grooves 713 can enhance the structural stability of the length adjusting member 71. During the working process of the level gauge, especially when the level gauge itself is affected by its own weight and external environmental factors (such as wind, ground vibration, etc.), this cooperation mode can effectively prevent the sliding part 711 from sliding accidentally, so that the level gauge support remains in a stable supporting state, and the measurement accuracy and accuracy of the level gauge are ensured. The elastic buckles 712 are designed to have certain elasticity and clamping force, which can reliably fix the sliding part 711 under various complex working conditions. Even during transportation or moving the level gauge on uneven ground, the elastic buckles 712 can ensure that the sliding part 711 will not be displaced due to vibration or collision, reducing the need for re-adjustment due to changes in the position of the level gauge, and improving the reliability of the entire measurement work.

[0038] The moving part 72 is a universal wheel mounted on the sliding part 711. The universal wheel can rotate freely by 360 degrees, so that the level support can easily change direction during movement, without the need to change the direction of travel by multiple adjustments as required by traditional directional wheels; in complex construction sites, there may be various obstacles and narrow passages, and the flexible turning feature of the universal wheel can allow the operator to quickly avoid obstacles and quickly reach the measurement location, improving work efficiency; when the level support is adjusted in a short distance, the universal wheel can conveniently realize translation operation; the operator can accurately move the level to the specified position according to the measurement needs, without the need to lift or drag the entire support, greatly reducing the labor intensity, and making the position adjustment of the level more convenient and efficient.

[0039] Please refer to Figure 1 and Figure 2 , the engineering cost level support also includes a sharp insertion part 80 mounted on the free end of the lower support part 122 for insertion into the soil. When performing engineering cost measurement on some soft or uneven ground, such as soil site, the sharp insertion part 80 can penetrate deep into the soil, so that the lower support part 122 of the level support has a more stable connection with the ground, greatly enhancing the ability of the support to resist tilting caused by uneven ground or external force, ensuring that the level remains vertical and horizontal during measurement, and improving the accuracy of measurement; soft ground such as soil is prone to deformation under the influence of the weight of the level or slight external vibration, causing the level to shake; after the sharp insertion part 80 is inserted into the soil, it can anchor the support to the ground, effectively reducing the shaking of the support and providing a stable support environment for the level, making the measurement data more reliable; under some soft ground conditions such as newly developed construction sites, muddy areas or filled areas, ordinary support support methods may sink into the ground or become unstable due to insufficient ground bearing capacity; the sharp insertion part 80 can more easily penetrate soft soil due to its sharp shape, and penetrate deep into the soil layer with certain bearing capacity, so that the level support can be stably placed on these special terrains, expanding the application range of the level; when measuring on a soil surface with a certain slope, the sharp insertion part 80 can be inserted obliquely into the soil, using the lateral friction and resistance of the soil to better fix the level support and prevent it from sliding down the slope, ensuring that the level remains stable when measuring on a slope, meeting the needs of engineering cost measurement under different terrain conditions.

[0040] The above only expresses the preferred technical solutions of the present application, which are described in more detail and specifically, but should not be understood as limiting the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, and the present application also intends to include these changes and modifications.
