Description

Technical Field

[0001] This utility model relates to the field of inspection instrument technology, specifically a fixing mechanism and an ionization chamber inspection instrument bracket. Background Technology

[0002] An ionization chamber survey instrument, also known as an ionizing radiation survey instrument, works based on the principle of an ionization chamber. It can accurately measure the dose of ionizing radiation in the environment and is widely used in nuclear energy, medical, radiotherapy, radiation protection, environmental monitoring, and other fields. The ionization chamber survey instrument bracket, through its structural design, allows for easy adjustment of the instrument's height and position to adapt to different surveying needs.

[0003] Existing ionization chamber monitoring instrument brackets typically use triangular supports for fixation and support, with the height of the instrument adjusted by regulating the support angles. However, because the three supports of the triangular support need to be adjusted to the same angle to level the top support base, and each of the three feet requires individual friction feet to prevent slippage, adjusting the angle by moving the support frame necessitates re-checking the friction feet for support after each adjustment. This cumbersome operation not only makes it difficult to accurately position the instrument on a horizontal plane but also increases the risk of the bracket tipping over. To address these issues, this invention provides a fixing mechanism and an ionization chamber monitoring instrument bracket to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing mechanism and an ionization chamber inspection instrument bracket. It solves the problem that existing ionization chamber inspection instrument brackets typically use triangular supports for fixing and support, with the height of the instrument adjusted by adjusting the support angle. However, because the three supports of the triangular support need to be adjusted to the same angle to level the top support base, and each of the three feet requires a friction foot to prevent the support frame from sliding, adjusting the angle by moving the support frame requires re-checking whether the friction foot is supportive. This is cumbersome, makes it difficult to accurately position the horizontal plane, and easily causes the bracket to slip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed mechanism and ionization chamber inspection instrument bracket, comprising a fixed base, wherein the fixed base includes a rotating disk rotatably connected within the fixed base, the top of the rotating disk having an arc-shaped groove, and sliding blocks, wherein three sets of sliding blocks are provided, the bottom of the sliding blocks having an arc-shaped groove, the arc-shaped groove being slidably connected within the arc-shaped groove, and the rotation of the arc-shaped groove driving the sliding of the arc-shaped groove.

[0007] Preferably, the fixed base further includes a bevel gear, which is rotatably connected to the bottom of the fixed housing. The bottom of the rotating disk has a toothed groove, and the bevel gear meshes with the toothed groove. The bevel gear drives the rotating disk to rotate, and a rotating handle is used to rotate the bevel gear.

[0008] Preferably, the fixed base further includes a worm gear, one end of which is fixedly connected to the outer end of a bevel gear, the worm gear driving the bevel gear to rotate, the other end of which is rotatably connected to the side wall of the control box, and a worm, both ends of which are rotatably connected to the control box, the worm meshing with the worm gear, the worm driving the worm gear to rotate, and a rotating handle fixedly connected to one end of the worm.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application provides a fixing mechanism and an ionization chamber inspection instrument bracket, solving the problems of existing ionization chamber inspection instrument brackets that typically use triangular supports for fixing and support, while adjusting the height of the ionization chamber inspection instrument by adjusting the support angle. However, because the three supports of the triangular support need to be adjusted at the same angle to level the top support base, and the three feet need to be fixed by setting friction feet to prevent the support frame from sliding, if the support frame is moved to adjust the angle, it is necessary to re-check whether the friction feet can support it after adjustment. This is not only cumbersome to operate, but also makes it difficult to accurately position the horizontal plane, and it is also easy for the bracket to slip.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model discloses a fixing mechanism and an ionization chamber inspection instrument bracket.
