Description
Technical field
The utility model relates to nuclear radiation detection technical field, specifically the fastening positioning device of GM counter tube in a kind of nuclear radiation detector.
Background technology
In nuclear radiation detector (hereinafter referred to as detector) field, as the GM counter tube of sensitive body, highly sensitive, pulse height is large, good stability and be subject to extensive employing.And GM counter tube will realize stable and accurate detection performance, must ensure that GM counter tube is fixed at detector interior location, the evenly unification of radial all directions, so the fastening location of GM counter tube seems particularly important.General GM counter tube structure is cylindrical, traditional mounting means is with two groups of positioning screw cap fastening GM counter tube two ends; Positioning screw cap is connected on clamping piston, and clamping piston is close to detector inwall, radial location, bumper and absorbing shock; Two connecting links, through two sections of clamping pistons, compress GM counter tube, axially directed.In actual mechanical process, because number of components is many, component processing precision is high, so processing cost is high, installation steps very complicated, plug easily occurs clamping stagnation, is unfavorable for the raising of production efficiency and the control of total cost.
Summary of the invention
The purpose of this utility model is exactly to overcome above-mentioned technical matters, and provides the fastening positioning device of GM counter tube in a kind of nuclear radiation detector, and this apparatus structure is simple, requirement on machining accuracy is low, and processing cost is low, and strength of joint is high, and damping performance is strong.
The technical scheme that the utility model solves the employing of its technical matters is: the fastening positioning device of GM counter tube in a kind of nuclear radiation detector, described fastening positioning device comprises and is arranged symmetrically with the identical snap ring of structure for a pair, described snap ring is made up of two surface levels of the inside and outside anchor ring of inner ring surface, outer ring surface and connection, inner ring surface is concentric with outer ring surface, two surface levels of described snap ring is provided with respectively between two parties the through hole for trip bolt.
In technique scheme, described snap ring inner ring surface and GM counter tube outer wall are fitted, and outer ring surface and detector inwall are fitted, and inner ring surface is concentric with outer ring surface.
In technique scheme, about described snap ring, two surface levels are the transition face of inner ring surface and outer ring surface, are close to detector circuit plate during installation.
In technique scheme, described snap ring two through hole is for installing trip bolt, and trip bolt is arranged symmetrically with snap ring, detector circuit plate by two groups, GM counter tube compresses, outer ring surface is provided with the handle hole coaxial with through hole in addition, is convenient to screwdriver operation, lock-screw.
In technique scheme, inside and outside described snap ring, anchor ring is consistent with the uniform wall thickness of surface level, keeps certain plasticity and elasticity, and when snap ring is by the extruding of footpath outward force, the plenum chamber between inner and outer ring shrinks, and provides variable nargin, ensures the bumper and absorbing shock of snap ring.
The fastening positioning device of GM counter tube in the utility model nuclear radiation detector, adopt high-quality engineering plastics processing, requirement on machining accuracy is low, processing cost is low, and strength of joint is high, and damping performance is strong, during assembling, mode of operation is easy, only need to fasten snap ring with trip bolt to install, the space that snap ring takies is little, is beneficial to detection circuit plate and places layout, detector cylindrical shell volume-diminished with matching simultaneously, requirement on machining accuracy is low, and processing cost is low, takes up room little.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the fastening positioning device radial direction of GM counter tube in the utility model detector is installed.
Fig. 2 is the schematic diagram that the fastening positioning device of GM counter tube in the utility model detector is axially installed.
Wherein: 1. trip bolt, 2. detector circuit plate, 3. snap ring, 4.GM counter tube, 5. detector cylindrical shell.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the present embodiment provides the fastening positioning device of GM counter tube in a kind of nuclear radiation detector, described fastening positioning device comprises a pair snap ring 3, described snap ring 3 is made up of two surface levels of the inside and outside anchor ring of inner ring surface, outer ring surface and connection, inner ring surface is concentric with outer ring surface, and two surface levels of described snap ring 3 are provided with through hole respectively between two parties.Described snap ring 3 radially symmetria bilateralis is arranged, surface level clamping detector circuit plate 2, GM counter tube 4 embeds detector circuit plate 2 groove, clamp with snap ring 3 inner ring surface, with two groups of trip bolts 1 through through hole on snap ring 3 and detector circuit plate 2, three is connected, realize radial fastening, snap ring 3 outer ring surface and detector cylindrical shell 5 inwall are fitted, thus realize GM counter tube 4 radial location; As shown in Figure 2, along GM counter tube 4 axis direction, by 4 snap ring 3 combination of two, GM counter tube 4 is clamped on detector circuit plate 2, inserts detector cylindrical shell 5 inwall vertically, thus realize GM counter tube 4 axial location.
