Detailed Description

Example (b): a level gauge support is shown in figure 1 and comprises a protective shell 3 with an opening at the upper end and a base 1 arranged in the protective shell 3 and used for fixing a level gauge body 6, wherein a supporting column 2 is fixedly connected to the lower surface of the base 1 in a vertical mode, a threaded hole 31 (shown in figure 4) in threaded connection with the supporting column 2 is formed in the center of the inner bottom surface of the protective shell 3, and a limiting block 21 for preventing the supporting column 2 from being screwed out of the protective shell 3 is fixedly connected to the bottom of the supporting column 2. The lower surface of the protective casing 3 is provided with three support rods 4 that support the protective casing 3.

Staff's accessible pillar 2 and the threaded connection of protective housing 3 revolve stopper 21 and revolve the spirit level body 6 and revolve to the protective housing 3 in to level body 6 has played the guard action. When the level body 6 is used, the protective shell 3 is screwed out of the level body 6, and then the level body 6 is stably erected on the ground through the 3 support rods 4, so that the normal work of the level body 6 is not affected. The protective housing 3 can also be used as a storage groove for placing a measurement notebook, a pen and other measurement articles for use which can be placed by a worker.

As shown in fig. 2, the support rod 4 includes three first connecting pipes 41, second connecting pipes 42 and third connecting rods 43 which are sleeved with each other, and the first connecting pipes 41, the second connecting pipes 42 and the third connecting rods 43 are slidably connected with each other. A first positioning bolt 412 is connected to the outer peripheral surface of the first connecting pipe 41 close to the end of the second connecting pipe 42 in a threaded manner, and the head of the first positioning bolt 412 is abutted against the outer peripheral surface of the second connecting pipe 42, so that the telescopic distance between the first connecting pipe 41 and the second connecting pipe 42 can be conveniently adjusted by a worker; the outer peripheral surface of the end part of the second connecting pipe 42 close to the third connecting rod 43 is connected with a second positioning bolt 413 by screw threads, and the extension distance between the second connecting pipe 42 and the third connecting rod 43 can be adjusted by setting the second positioning bolt 413. When the supporting rod 4 is completely contracted, the whole space occupation of the supporting rod 4 is saved, and the moving and the transportation are convenient.

A baffle 431 is fixedly connected to a side wall of one end of the third connecting rod 43, which is away from the second connecting pipe 42, so that when the staff wants to stretch the supporting rod 4, the staff can stretch the third connecting rod 43 out of the second connecting pipe 42 through the baffle 431. When the end of the third connecting rod 43 contacts the ground, the second connecting tube 42 can be pulled out of the first connecting tube 41 by stepping on the baffle 431, so that the whole supporting rod 4 is pulled out. The end of the third connecting rod 43 is set to be a taper shape, so that the supporting rod 4 can be suitable for more complicated ground, when the ground is used, the supporting rod 4 can be conveniently inserted into the ground, the stability of the supporting rod 4 is improved, the supporting rod 4 is firmly arranged on the ground, and the leveling instrument body 6 is safer to use. Meanwhile, the baffle 431 can prevent the support rod 4 from continuously sinking when the soil is soft, and the balance of the bracket of the level body 6 is kept.

As shown in fig. 3, in order to facilitate the leveling of the leveling instrument support by the staff, a circular leveling bubble 11 is fixedly connected to the upper surface of the base 1, so that the bubble in the circular leveling bubble 11 is positioned at the center of the circular leveling bubble 11 by adjusting the height and the angle of the 3 support rods 4, thereby leveling the leveling instrument support.

As shown in fig. 4 and 5, three through holes 32 have been evenly opened on the bottom surface in the protective housing 3 with the center of the pillar 2 as the center of a circle, a limiting pipe 321 is arranged in each through hole 32, two connecting rods 3211 are fixedly connected to the outer peripheral surface of the limiting pipe 321, the two connecting rods 3211 are coaxially arranged, and the axes of the two connecting rods 3211 pass through the center of the limiting pipe 321, the ends of the two connecting rods 3211 are rotatably connected to the inner wall of the through hole 32, the first connecting pipe 41 is arranged in the limiting pipe 321, and is connected to the limiting pipe 321 in a sliding manner along the axial direction of the limiting pipe 321, so that a worker can slide the contracted supporting rod 4 into the protective housing 3, thereby saving space occupation and facilitating transportation. The outer peripheral surface of the limiting pipe 321 is in threaded connection with a fixing bolt 322, and the head of the fixing bolt 322 is abutted against the outer peripheral surface of the first connecting pipe 41, so that the first connecting pipe 41 and the limiting pipe 321 are conveniently positioned. The outer peripheral surface of the first connecting pipe 41 is provided with a sliding groove 411 for accommodating the fixing bolt 322 to slide along the length direction of the first connecting pipe 41, so that the first connecting pipe 41 and the limiting pipe 321 are prevented from rotating relative to each other, and meanwhile, the sliding groove 411 can limit the first connecting pipe 41 in the limiting pipe 321 to prevent the first connecting pipe 41 from separating from the limiting pipe 321.

The top of the protective shell 3 is connected with a protective cover 5 in a threaded manner, and the top of the protective cover 5 is provided with a handle 51. After the level body 6 is completely accommodated in the protective shell 3, the protective shell 3 can form a closed space due to the arrangement of the protective cover 5, and the protection effect of the protective shell 3 is enhanced. Handle 51 not only is convenient for the staff to carry out the screwing of visor 5, is convenient for the staff to remove the spirit level support moreover.

The working process is as follows: when using this surveyor's level support, the staff unscrews visor 5, unscrews protective housing 3 with base 1 through stopper 21 of 2 bottoms of pillar, then installs surveyor's level body 6 on base 1, and then, the staff can step on baffle 431 with the foot to stretch out bracing piece 4, through the height and the angle of adjusting 3 bracing pieces 4, be located the central point of circle level bubble 11 with the bubble in the circle level bubble 11, thereby adjust base 1 to the horizontality and just can use.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
