Technical Field

[0001] The utility model relates to the technical field of monitoring prisms, and more specifically, to a supporting and fixing device for a monitoring prism. Background Art

[0002] A monitoring prism is an optical element used to measure optical properties. It is usually used in engineering measurements as a target point to reflect the laser emitted by a total station. When the monitoring prism is in use, a supporting and fixing device is used to fix the monitoring prism on the target point. Most of the existing supporting and fixing devices are L-shaped iron frames with openings. The supporting and fixing devices are fixed to the target point by inserting expansion screws into the openings at the target point. When the monitoring prism is actually removed in the fixed manner, it is also necessary to rotate the studs on the expansion screws before taking out the supporting and fixing devices, which is not convenient enough.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a supporting and fixing device for monitoring prism, including a fixing rod 1, a fixing shaft 4 is fixedly installed on the fixing rod 1, a rotating rod 2 is sleeved on the surface of the fixing shaft 4, a threaded hole is provided in the middle of the rotating rod 2, a meshing half ring 1 5 and a meshing half ring 2 6 are meshedly connected in the threaded hole, a half nut 1 7 and a half nut 2 8 are fixedly installed on the top of the meshing half ring 1 5 and the meshing half ring 2 6 respectively, an insert block 9 is fixedly installed on the rear end of the half nut 1 7, a slot 10 is provided on the front end of the half nut 2 8, a locking hole 11 is provided on the right end of the rotating rod 2, and a locking block 12 is inserted into the inner cavity of the locking hole 11;

[0023] By providing two rotatable rotating rods 2, after the half nut 1 7 is screwed down with a wrench, the two rotating rods 2 can be rotated first and removed from the expansion screw, and then the half nut 1 7 and the half nut 2 8 on the expansion screw can be directly separated, and the meshing half ring 1 5 and the meshing half ring 2 6 can also be removed. During the disassembly process, there is no need to disassemble the fixed expansion screw, and the operation is simple and convenient.

[0024] The top of the fixed rod 1 is rotatably connected with a rotating shaft 14, the right end of the rotating shaft 14 is fixedly installed with a monitoring prism body 13, the left end of the rotating shaft 14 is fixedly installed with a positioning ring 15, the left side of the positioning ring 15 is provided with a strip groove 3, and the left side of the fixed rod 1 is fixedly installed with a pointer 16;

[0025] By opening a plurality of strip grooves 3 on the left side of the rotating shaft 14, every time the rotating shaft 14 rotates one degree, another strip groove 3 will be placed under the pointer 16. At this time, the pointer 16 will vibrate when moving from one strip groove 3 to another strip groove 3. The operator can accurately judge the rotation angle according to the number of vibrations, thereby improving the accuracy of the monitoring prism body 13 when in use.

[0026] There are two rotating rods 2, which are exactly the same in shape and size and are in close contact.

[0027] Providing two rotating rods 2 of the same size and shape can ensure that the threaded holes between the two can be pieced together into a complete threaded hole, so as to ensure that the half ring 1 5 and the half ring 2 6 can be smoothly engaged.

[0028] The insert block 9 is inserted into the slot 10, and the half nut 1 7 and the half nut 2 8 fit tightly together;

[0029] After the meshing half ring 1 5 and the meshing half ring 2 6 are removed from the central screw, the insert block 9 can be inserted into the slot 10 to assemble the meshing half ring 1 5 and the meshing half ring 2 6 together to achieve a recycling effect.

[0030] Among them, the tops of the half nut 1 7 and the half nut 2 8 are fixedly installed with semicircular rings;

[0031] By providing a semicircular ring, the half nut 1 7 and the half nut 2 8 can be separated from the end portion of the central screw, making it easier to directly screw them.

[0032] The length of the locking block 12 is equal to twice the depth of the locking hole 11, and the shape of the locking block 12 is "U"-shaped;

[0033] The two rotating rods 2 are fixed by inserting the locking block 12 into the locking hole 11, so as to prevent the rotating rods 2 from being separated and falling off during normal use, thereby ensuring the safety thereof.

[0034] The bottom end of the pointer 16 is a triangle, and the bottom end of the pointer 16 is inserted into the strip groove 3;

[0035] The pointer 16 arranged in a triangle shape can be in contact with the strip groove 3 well.

[0036] Among them, the half nut 1 7 and the half nut 2 8 are both located above the rotating rod 2, and the lengths of the meshing half ring 1 5 and the meshing half ring 2 6 are equal and are both located at half the length of the threaded hole opened on the rotating rod 2;

[0037] It is ensured that the meshing half ring 1 5 and the meshing half ring 2 6 can be smoothly rotated downwards for smooth removal.

[0038] The working principle and use process of this utility model:

[0039] During installation, a hole is drilled at the target position, and then the housing of the expansion screw is placed, and then the center screw is inserted into the meshing half ring 1 5 and the meshing half ring 2 6, and then the center screw is inserted into the housing. When the center screw contacts the semicircular rings above the half nut 1 7 and the half nut 2 8, the device is fixed at the target point;

[0040] Then adjust the angle of the monitoring prism body 13 and rotate the left end of the rotating shaft 14. When the rotating shaft 14 rotates, different strip grooves 3 can be driven to be located under the pointer 16. When one of the strip grooves 3 leaves the pointer 16, the pointer 16 will be inserted into another strip groove 3, thereby emitting a slight vibration to indicate that it has rotated one degree.

[0041] When the device needs to be removed, rotate half nut 1 7 and half nut 2 8 counterclockwise to move the meshing half ring 1 5 and meshing half ring 2 6 downward in the threaded hole, separate the center screw from the semicircular ring, then pull out the locking block 12, rotate the two rotating rods 2 to both sides respectively, and the device can be directly removed from the center screw. Finally, separate half nut 1 7 and half nut 2 8, and take out the meshing half ring 1 5 and meshing half ring 2 6 from the center screw.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
