Description

Technical Field

[0001] This utility model relates to the field of engineering measurement and counting, and in particular to a support for a level measuring instrument. Background Technology

[0002] A level (also known as a spirit level) is a common measuring tool used in engineering surveying for measuring angles. It is mainly used to determine whether an object is horizontal or vertical, and to determine the angle of inclination of an object relative to a horizontal position. Levels are widely used in various fields such as machinery, instrument manufacturing, construction, and aviation. When in use, a support frame is typically used as an auxiliary device to support and fix the level, providing a stable and reliable support platform to ensure the accuracy and reliability of the measurement results.

[0003] Existing level supports only provide stabilization. When the level is mounted on the support, its height and angle remain fixed. To change the level's height or angle, the entire support and level must be moved, impacting measurement efficiency. Frequent movement of the support also significantly affects measurement accuracy. Furthermore, existing level supports are inconvenient to store or carry. When the level is fixed in the center of the support, the extended support can obstruct operators from getting close to the instrument for operation and use. Summary of the Invention

[0021] Specifically, the supporting block is connected by a plurality of connecting columns 3 from an upper supporting block 1 and a lower supporting block 2, and a hollow cavity is formed in the middle part, thereby reducing the overall weight of the supporting block. Of course, in order to facilitate the storage of some commonly used auxiliary tools (such as calibrating calipers, standard rulers, standard blocks, measurement probes, fixing clamps, wiping cloths, cleaning agents, notebooks, pens, etc.) during horizontal measurement, a horizontally pullable storage hopper 4 can also be provided on the upper supporting block 1, and a convenient gripping hand 5 is provided on the pull side outer wall of the storage hopper 4.

[0022] The tripod comprises a connecting block 6 fixed to the bottom surface of the lower supporting block 2, a telescopic rod 7 vertically downwardly arranged in the center of the connecting block 6, three outwardly turning opening or inwardly turning folding supporting legs 8 evenly and uniformly spaced in the circumferential direction and hingedly connected to the outer side of the connecting block 6 of the telescopic rod 7, and three inclined push rods 9 hingedly connected to the telescopic end of the telescopic rod 7; the three inclined push rods 9 correspond to the three supporting legs 8 one by one, and the end of each inclined push rod 9 away from the telescopic rod 7 is hingedly connected to the inner middle part of a supporting leg 8, so that the telescopic rod 7 can drive the inclined push rod 9 to push and pull the supporting leg 8 through the telescoping of the telescopic rod 7, and the opening or folding of the three supporting legs 8 can be easily realized.

[0023] The height adjusting base comprises a pair of horizontal guide rods 10, which are parallel to each other, and the two ends of each horizontal guide rod 10 are fixedly connected to the top surface of the upper supporting block 1 through a fixed lug plate 11. A pair of driving plates 12 are slidably arranged on the two horizontal guide rods 10, and the two ends of each driving plate 12 are movably sleeved on the two horizontal guide rods 10, so that the two driving plates 12 can slide in the axial direction of the horizontal guide rods 10. A bidirectional screw rod 13 is also arranged at the center of the two driving plates 12, and the bidirectional screw rod 13 can be fixed to the top surface of the upper supporting block 1 through a pair of hinged lug plates 14. The bidirectional screw rod 13 has left-handed threads 15 and right-handed threads 16 with opposite rotation directions. At this time, a left threaded hole matched with the left-handed threads 15 is formed in one of the driving plates 12, and a right threaded hole matched with the right-handed threads 16 is formed in the other driving plate 12, so that the two driving plates 12 can be driven to move towards or away from each other by rotating the bidirectional screw rod 13. In addition, a bearing plate 17 is horizontally arranged above the two driving plates 12, and at least one pair of inclined support rods 18 is hingedly connected to the bottom surface of the bearing plate 17. The distal ends of each pair of inclined support rods 18 are respectively hingedly connected to the two driving plates 12. To ensure the stability of the bearing plate 17, two pairs of inclined support rods 18 are preferably arranged above the two horizontal guide rods 10.

[0024] To facilitate the rotation of the bidirectional screw rod 13 along the axis, a driving rotary wheel 19 is coaxially fixed to one end of the bidirectional screw rod 13 and located outside the bearing plate 17. A holding handle 20 is arranged on the driving rotary wheel 19, so that the driving rotary wheel 19 can be rotated by holding the handle 20, thereby easily driving the bidirectional screw rod 13 to rotate and completing the lifting adjustment of the bearing plate 17. In addition, to make the lifting of the bearing plate 17 more stable, a pair of limiting guide grooves 21 is vertically arranged on one of the opposite side walls of the upper supporting block 1 and the lower supporting block 2, and a pair of limiting insertion rods 22 is arranged on the bearing plate 17 and can be fitted and inserted into the limiting guide grooves 21. Through the fitting and insertion of the limiting guide grooves 21 and the limiting insertion rods 22, the deflection of the bearing plate 17 during lifting can be effectively avoided.

[0027] When the height of the horizontal measuring instrument is adjusted, the driving wheel 19 is rotated by holding the handle 20, so that the bidirectional screw rod 13 rotates along the axis thereof, and in the rotating process, the two driving plates 12 screwed on the left-hand thread 15 and the right-hand thread 16 of the bidirectional screw rod 13 are simultaneously translated towards each other, so that the pair of inclined struts 18 hinged to the two driving plates 12 are lifted up to the carrying plate 17, and the height of the horizontal measuring instrument installed on the carrying plate 17 is easily adjusted.

[0028] When the rotation angle of the horizontal measuring instrument is adjusted, the positioning bolt 26 is loosened outward, then the horizontal rotary table 24 is rotated to adjust the angle of the horizontal measuring instrument, the positioning bolt 26 is tightened inward after the adjustment is completed, the inner end of the positioning bolt 26 is clamped on the side wall of the fixed table 23, the rotation angle of the horizontal rotary table 24 is fixed, and the angle rotation and fixation of the horizontal measuring instrument are easily realized.

[0029] After use, the horizontal measuring instrument is directly removed, and the telescopic end of the telescopic rod 7 is inwardly telescoped, so that the supporting legs 8 are inwardly telescoped under the driving of the inclined push rod 9, and the storage work is easily completed.

[0030] The whole horizontal measuring instrument support can not only stably support the horizontal measuring instrument and easily adjust the height or the rotation angle of the horizontal measuring instrument as required, but also is convenient to store and carry, the operator does not need to move the horizontal measuring instrument and the support as a whole to find a suitable angle position, the accuracy of measurement is ensured, the measurement efficiency is improved, the supporting legs of the tripod do not block the operator during use, and the operator can easily operate the horizontal measuring instrument at a close distance.
