Description

Technical Field

[0001] This utility model relates to the technical field of measuring instrument support bases, and in particular to a measuring instrument support base with adjustable height. Background Technology

[0002] In the field of engineering construction, measuring instruments, such as levels, total stations, and laser thickness gauges, rely on the stable support and height adaptation of their support bases. Adjustable height measuring instrument support bases have become core auxiliary equipment for various measuring scenarios because they can flexibly adapt to different measurement target heights and cope with uneven ground.

[0003] However, in outdoor engineering surveying scenarios involving soft soil, such as muddy construction sites, collapsible loess areas, soft grasslands, and geological exploration, the grounding end is a sharp point contact, making it more susceptible to the influence of uneven local soil density. Within the same support area, there may be localized hard soil blocks and soft mud depressions, resulting in significant differences in the degree of sinking of different support legs. As a result, the instrument cannot be kept in a horizontal position during measurement, which greatly reduces the accuracy of the device during measurement.

[0004] Therefore, it is necessary to provide an adjustable height measuring instrument support base to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides an adjustable height support base for measuring instruments, which solves the problem that traditional devices cannot guarantee that the device is in a horizontal state when facing different soil types, thus affecting the accuracy of the test.

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable height measuring instrument support base comprising: a device body, on which a support structure, a lifting structure, and a device support rod are provided; the support structure includes a slide groove formed on the device support rod, with symmetrical slots formed on the slide groove; a circular block is provided on the slide groove, with a through groove formed on the circular block; a fixed slider is fixedly installed on the circular block; a pull block is provided on the circular block, with a limiting slider fixedly installed on the pull block; a telescopic slider is installed at the end of the pull block; an elastic element for resetting the telescopic slider is arranged around the pull block; an inclined rod is provided on the circular block, with a shaft for connecting the inclined rod and the circular block; and a horizontal plate is provided on the device support rod, the horizontal plate being rotatably connected to the inclined rod via the shaft.

[0007] Preferably, the lifting structure includes a threaded rod on the main body of the device, a rotating block installed at the bottom of the threaded rod, a rotating bearing installed at the top of the threaded rod, and a mounting base plate on the lifting structure.

[0008] Preferably, a guide rod is installed at the bottom of the mounting base plate, a limiting block is installed at the bottom of the guide rod, and a nut block is provided on the lifting structure.

[0009] Preferably, the main body of the device is provided with a device base plate, a fixing block is installed at the bottom of the device base plate, and a vertical rod is provided on the fixing block.

[0010] Preferably, the bottom of the vertical rod is fixedly connected to the device support rod, and the vertical rod is rotatably connected to the fixed block through a shaft.

[0011] Preferably, a level is mounted on the base plate of the device.

[0012] Preferably, the bottom of the support rod of the device is equipped with a fixed tip.

[0013] Compared with related technologies, the adjustable height measuring instrument support base provided by this utility model has the following advantages: This invention provides an adjustable height measuring instrument support base. When using the device, in soft soil, the pull block can be pulled, causing the telescopic slider to retract. The circular block then slides downwards along the groove, simultaneously moving the horizontal plate via a diagonal rod. When it reaches the lower slot, the elastic element uses its own elasticity to re-enter the telescopic slider into the slot, thus unfolding and fixing the horizontal plate. The horizontal plate on this device increases the contact area with the ground, allowing for more even force distribution between the base and the ground, reducing the impact of local soil variations on support stability, and preventing instability caused by localized subsidence. This enhances the stability of the device and improves measurement accuracy. Attached Figure Description

[0024] The working principle of the adjustable height measuring instrument support base provided by this utility model is as follows: When using the device, in soft soil, the pull block 206 can be pulled. At this time, the pull block 206 will drive the limiting slider 205 to slide, and the limiting slider 205 will compress the elastic element 208. As the pull block 206 moves, it will drive the telescopic slider 211 to retract. At this time, the round block 207 can slide down along the slide groove 201. At the same time, the round block 207 will drive the horizontal plate 204 to move through the inclined rod 203. When it reaches the lower slot 202, the elastic element 208 will push the limiting slider 205 to reset through its own elastic force. As the limiting slider 205 resets, it will drive the telescopic slider 211 to re-enter the slot 202, thereby allowing the horizontal plate 204 to unfold and be fixed.

[0025] Compared with related technologies, the adjustable height measuring instrument support base provided by this utility model has the following advantages: When using the device, in soft soil, the pull block 206 can be pulled, which will cause the telescopic slider 211 to retract. At this time, the round block 207 can slide down along the groove 201. Simultaneously, the round block 207 will drive the horizontal plate 204 to move through the inclined rod 203. When it reaches the lower slot 202, the elastic element 208 will use its own elastic force to drive the telescopic slider 211 back into the slot 202, thereby causing the horizontal plate 204 to unfold and be fixed. The horizontal plate on this device can increase the contact area with the ground. The large contact area can make the force on the base and the ground more even, reduce the impact of local soil differences on the support stability, avoid the instability of the device support caused by local sinking, enhance the stability of the device, and thus improve the measurement accuracy.
