Description

Technical Field

[0001] The utility model relates to the technical field of levels, in particular to a portable level support. Background Art

[0002] A level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. A level stand is a device used to support a level, usually consisting of a mounting frame for the level and a tripod at its lower end, used to keep the level horizontal and stable.

[0003] The surveying and mapping work of the level instrument is mostly carried out outdoors, and generally there is more than one surveying point. During the transfer of the level instrument, the surveyor usually folds up the tripod and carries it on his shoulders for transfer. Sometimes, in order to save trouble, the level instrument is not even removed from the mounting bracket. Such operation not only consumes a lot of physical energy of the surveyor, but also easily causes bumps and damages to the level instrument. Utility Model Content

[0006] In one embodiment, a fixing block is fixedly provided on each of the supporting legs, the first threaded hole is provided on the fixing block, a sliding groove is provided on each of the mounting blocks, and the mounting block is slidably connected to the fixing block via the sliding groove.

[0007] In one embodiment, the mounting block includes an upper part and a lower part, the upper part is used to achieve disassembly and assembly at the first threaded hole, and the lower part is used to provide a mounting position for the rotating wheel, and the upper part and the lower part are connected by a spring.

[0008] In one embodiment, the rotating wheel is a universal wheel.

[0009] In one embodiment, a rubber pad is provided on a surface of the support rod for contacting the second screw.

[0010] In summary, in this application, a portable level stand has the following beneficial effects compared with the prior art:

[0011] After the staff unfolds and adjusts the level, the second screw can be used to clamp the support rod to fix the position of the support leg, making it less likely to change due to external force, thereby improving the stability during the measurement process;

[0012] When it is necessary to transfer to the next surveying point, the three mounting blocks can be installed at the first threaded holes on the lower side so that the rotating wheels can contact the ground, so that the tripod can be held to move, which effectively reduces the physical consumption of workers during the transfer process, is safer, and is not easy to cause the level to bump;

[0020] See also Figure 1 , Figure 2 In one embodiment, a portable level stand includes a level stand body 1, three mounting blocks 12, and a support column 20.

[0021] See also Figure 1 , Figure 2 The leveling instrument support body 1 includes a mounting frame 2 for mounting the leveling instrument and a tripod 3 at the lower end of the mounting frame 2 .

[0022] See also Figure 1 , Figure 2, each of the three supporting legs 4 of the tripod 3 is provided with a mounting block 12, and each mounting block 12 is rotatably provided with a rotating wheel 15, and the rotating axis of the rotating wheel 15 is in the horizontal direction. Each supporting leg 4 is provided with two first threaded holes 6, one above and one below, and each mounting block 12 is provided with a first through hole, and a first screw 19 is provided, which can pass through the first through hole and be screwed into the first threaded hole 6, so that the mounting block 12 can be detached and assembled at the first threaded hole 6. When the mounting block 12 is installed at the first threaded hole 6 on the lower side, the lower end of the rotating wheel 15 extends downwardly beyond the supporting leg 4 along the length direction of the supporting leg 4, so that the rotating wheel 15 can touch the ground; when the mounting block 12 is installed at the first threaded hole 6 on the upper side, the lower end of the rotating wheel 15 will not extend downwardly beyond the supporting leg 4 along the length direction of the supporting leg 4, so that the lower end of the supporting leg 4 can touch the ground. When transfer is required, the three mounting blocks 12 can be installed at the first threaded holes 6 on the lower side. When transfer is not required, the mounting block 12 can be installed at the first threaded hole 6 on the upper side.

[0023] See also Figure 1 , Figure 2 In one embodiment, a fixing block 5 in the shape of a "convex" is fixedly provided on each supporting leg 4 by welding, the first threaded hole 6 is provided on the fixing block 5, and a slide groove 16 is provided on each mounting block 12, the slide groove 16 penetrates the mounting block 12 in a direction parallel to the length of the supporting rod 21, and the cross section of the slide groove 16 is also in the shape of a "convex", and the mounting block 12 is slidably connected to the fixing block 5 through the slide groove 16. This arrangement makes the operation more convenient and the structure more stable.

[0024] See also Figure 1 , Figure 2 In one embodiment, the mounting block 12 is composed of an upper part 13 and a lower part 14, both of which are slidably connected to the fixing block 5 through the slide groove 16, the upper part 13 is used to realize the disassembly and assembly at the first threaded hole 6, the first through hole and the first bolt are arranged on the upper part 13, and the lower part 14 is used to provide an installation position for the rotating wheel 15, and the upper part 13 and the lower part 14 are connected by a spring 17, and both ends of the spring 17 are connected by welding. With this arrangement, when the ground is bumpy during transportation, the spring 17 can play an effective shock-absorbing and buffering role to better protect the level.

[0025] See also Figure 1 , Figure 2In one embodiment, preferably, the rotating wheel 15 is a universal wheel. This configuration enables more flexible steering and greater convenience during transportation.

[0026] See also Figure 1 , Figure 2 The support column 20 is fixedly connected to the lower end of the center of the mounting frame 2 in the vertical direction downward, and three support rods 21 are hingedly arranged at the lower end of the support column 20. The rotating axes of the support rods 21 are all in the horizontal direction. A crimping portion 7 is arranged on each of the support legs 4, and the crimping portion 7 is composed of a vertical plate 8 and a connecting rod 9. The vertical plate 8 is arranged on the side of the support rod 21 and there is a certain distance between the vertical plate 8 and the support rod 21. A second threaded hole 10 and a matching second screw 11 are arranged on the crimping portion 7. The axial direction of the second screw 11 is perpendicular to the side of the support rod 21. When the support rod 21 is rotated to the crimping portion 7, the support rod 21 can be pressed against the support leg 4 by tightening the second screw 11 in the second threaded hole 10, so as to achieve a limiting effect on the support rod 21 and a certain fixing effect.

[0027] See also Figure 1 , Figure 2 In one embodiment, a rubber pad 22 is adhered to a surface of the support rod 21 for contacting the second screw 11, and the support rod 21 contacts the second screw 11 through the rubber pad 22. In this way, the second screw 11 can be tightened to cause the surface of the rubber pad 22 to be concave, thereby obtaining a greater friction force and a more stable limiting effect.

[0028] Working principle: After the staff unfolds and adjusts the level, the second screw 11 can be used to clamp the support rod 21 to fix the position of the support leg 4, so that it is not easily changed by external force, thereby improving the stability during the measurement process; when it is necessary to transfer to the next surveying point, the three mounting blocks 12 can be installed at the first threaded hole 6 on the lower side, so that the rotating wheel 15 can contact the ground, so that the tripod 3 can be held for movement, which effectively reduces the physical exertion of the workers during the transfer process, is safer, and is less likely to cause the level to be bumped; after arriving at the next surveying point, the mounting block 12 is removed from the first threaded hole 6 on the lower side, and the level is slightly adjusted to continue measuring, which is convenient and quick.
