[0016] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0017] Example 1

[0018] This embodiment provides a rotating window for a level instrument, such as Figure 1 and Figure 2 As shown, the rotating window includes a bottom and a window portion 1 that are rotatably connected, and the base 2 is provided with a through hole 201; the window portion 1 is hollow inside, and is indirectly provided with windows and columns around it, and the bottom passes through the through hole 201 and rotates in the through hole 201; the window portion 1 can rotate 360° relative to the base 2, and when the base 2 is fixed, the rotation of the window portion 1 is realized, and the window portion 1 only needs to be rotated manually and gently, which solves the problem that the level column will block the light and form a shadow in some cases, affecting the use. A protective cover made of transparent material can be set at the position of the window to prevent dust from entering and extend the service life of the level.

[0019] In this embodiment, the rotational connection between the base 2 and the window portion 1 can be that the bottom of the window portion 1 is directly fastened around the through hole 201 of the base 2 and mechanically rotated. At this time, the contact positions between the window portion 1 and the base 2 are polished to form a polishing area 202; it can also be that a bearing or ball bearing is provided between the base 2 and the window portion 1; or the base 2 and the window portion 1 are integrally formed, and the base 2 can rotate 360° relative to the window portion 1.

[0020] In a preferred embodiment, the window portion 1 is fixed with at least two rotating blocks 101, and the rotating blocks 101 are buckled on the inner circumference of the through hole 201 of the base 2, and the rotating blocks 101 can rotate 360° relative to the base 2. The rotating block 101 is arc-shaped, which can fix the base 2 and the window portion 1 without affecting the rotation effect. Preferably, there are four rotating blocks 101, which are symmetrically buckled on the through holes 201 of the base 2, and the rotating blocks 101 can rotate 360° relative to the base 2. The four rotating blocks 101 can make the relative position of the base 2 and the window portion 1 more stable, not easy to shake and damage, so that the marking of the level is more accurate. The rotating blocks 101 and the base 2 are in contact with the polished area that has been polished, which can reduce the resistance during rotation and make it more convenient to rotate.

[0021] In a preferred embodiment, the base 2 is provided with a plurality of countersunk holes 203. The base 2 can be fixed to the level by screws, and is easy to disassemble and maintain, and can be used with different levels. In order to further facilitate the disassembly and installation of the rotating window for the level, the window portion 1 is provided with an avoidance area 104 at the position corresponding to the countersunk holes 203.

[0022] The present embodiment provides a rotating window for a spirit level, in which the window portion can rotate 360° relative to the base through a rotating block 101, thereby solving the problem that the spirit level column may block light and form a shadow in some cases, thus affecting the use. The problem of the column blocking light can be easily solved by simply manually rotating the window portion 1, and the spirit level can be adapted for use with most spirit levels on the market.

[0023] Example 2

[0024] Compared with the first embodiment, the main difference of this embodiment is that the rotation connection mode of the base 2 and the window portion 1 is different. Figure 3 and Figure 4 As shown, the base 2 and the window portion 1 are connected by a retaining spring 3. A rotation area is provided at the bottom of the window portion 1, and the rotation area includes a track and a rotating block 101. The track includes a rotating track 102 and a limiting track 103. The retaining spring 3 can be detachably installed in the limiting track 103, and the rotating block 101 abuts against the retaining spring 3. The rotating track 102 is located above the relative position of the limiting track 103. The diameter of the rotating track 102 is larger than the diameter of the limiting track 103. When the base 2 is sleeved in the rotation area of ​​the window portion 1, it can be directly sleeved on the rotating track 102, and then the retaining spring 3 is sleeved on the limiting track 103 and fixes the base 2 and the window portion 1 together with the rotating block 101, so that the window portion 1 can rotate 360° relative to the base. At this time, the retaining spring 3 is stationary relative to the rotating block 101, and rotates relative to the base 2 together with the window portion 1.

[0025] In order to facilitate the disassembly of the clamping spring 3, the clamping spring 3 is a C-shaped clamping spring.

[0026] In order to reduce the resistance when the base 2 and the window part 1 rotate, a polishing area 202 is provided at the position where the base 2 contacts the retaining spring 3, and the position where the base 2 contacts the window part 1 is also polished.

[0027] The present embodiment provides a rotating window for a spirit level, in which the window portion 1 can rotate 360° relative to the base through a track in the rotating area, and is easy to disassemble, thereby solving the problem that the spirit level column will block the light and form a shadow in some cases, thereby affecting the use. The problem of the column blocking the light can be easily solved by simply manually rotating the window portion 1, and the spirit level can be adapted for use with most spirit levels on the market.
