Abstract
The utility model relates to a vibration damper of a radioactive detector, which is characterized in that the vibration damper mainly comprises a fixed plate, a movable plate, a bolt, a nut (comprising a flat pad and an elastic pad) and a compression spring; the radioactive detector is arranged on a movable plate, the movable plate is arranged on a fixed plate through a bolt and a compression spring and can slide up and down along the direction of a bolt rod; when the fixed plate is impacted externally, the movable plate is buffered under the action of the compression spring, the radioactive detector is weakened by vibration, and the radioactive detector on the movable plate is prevented from being damaged by vibration.
Description
Technical Field
The utility model relates to a nuclear radiation detects technical field, especially relates to a radioactivity detector vibration damper for the vibration damping under the environment of easily receiving impact and vibration is applied to the radioactivity detector.
Background
The radioactive detector is used for detecting whether a measured object contains radioactive substances, and the radioactive detector contains precision devices such as a glass photomultiplier tube and an electronic circuit, and is damaged or measurement accuracy is reduced due to vibration. In some special occasions, such as the radioactive detector installed on a grab bucket or an off-road locomotive, the radioactive detector is easy to be strongly vibrated due to external impact, in the applications, the vibration is generally reduced by adopting a foam pad mode, but the vibration reduction effect of the foam pad is poor because the grab bucket or the off-road locomotive has large vibration amplitude and high frequency, and the common foam pad is made of rubber material and is easy to age and lose elasticity, thereby influencing the vibration reduction effect.
Disclosure of Invention
The utility model discloses aim at overcoming the poor problem of current radioactivity detector damping effect, adopt compression spring to carry out the damping to the radioactivity detector.
The utility model discloses the content as follows:
the vibration damper for the radioactive detector mainly comprises a fixed plate, a movable plate, a bolt, a nut and a compression spring; the fixing plate is provided with at least 3 threaded holes, the size of each threaded hole is matched with the thread of the bolt, and the threaded holes are distributed around the fixing plate; the movable plate is provided with through holes with the same number as the threaded holes of the fixed plate, the diameter of each hole is larger than the diameter of each bolt, the bolts can freely slide in the through holes, and the positions of the through holes correspond to the positions of the threaded holes of the fixed plate one by one; the head of bolt upwards passes the fly leaf, and compression spring overlaps on the bolt, twists the screw hole at the fixed plate with the bolt, uses the nut to fasten again simultaneously.
The bolt is a half-thread bolt, only the end part of the bolt is provided with threads, and the contact section of the bolt and the spring is a polished rod.

Detailed Description
The following description is provided for illustrative purposes, and it is to be understood that the present invention is not limited to the specific embodiments disclosed herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
Please refer to fig. 1, fig. 2, and fig. 3. It should be noted that the drawings provided in the present embodiment are only schematic and illustrative of the basic concept of the present invention, and the drawings only show the structures related to the present invention rather than the shapes and the dimensions according to the actual implementation, the forms and the proportions of the actual implementation can be changed at will, and the structural layout can be more complicated.
The invention will be further explained with reference to the drawings and an embodiment thereof:
the utility model relates to a vibration damper of a radioactive detector, which mainly comprises a fixed plate (1), a movable plate (5), a bolt (3), a nut (2) (comprising a flat pad and an elastic pad) and a compression spring (4); the fixing plate (1) is provided with at least 3 threaded holes, the size of each threaded hole is matched with the thread of the bolt (3), and the threaded holes are distributed around the fixing plate (1); the movable plate (5) is provided with through holes the number of which is the same as that of the threaded holes of the fixed plate (1), the diameter of each through hole is larger than that of a bolt, the bolts (3) can freely slide in the through holes, and the positions of the through holes correspond to the positions of the threaded holes of the fixed plate (1) one by one; the head of the bolt (3) faces upwards, penetrates through the movable plate (5), the compression spring (4) is sleeved on the bolt (3), the bolt (3) is screwed in a threaded hole of the fixed plate (1), meanwhile, the nut (2) is used for fastening again, and the nut is fixedly additionally provided with the flat pad and the elastic pad, so that the nut is prevented from being loosened by vibration; the radioactivity detector (6) is fixedly arranged on the movable plate (5). After the installation is finished, the movable plate (5) is pressed downwards by hand, the movable plate (5) can freely move downwards along the bolt (3), meanwhile, the compression spring (4) is compressed, and after the hand is released, the movable plate (4) can automatically recover to the initial position under the restoring force action of the compression spring (4).
In order to freely compress and release the compression spring outside the bolt, the bolt adopts a half-thread bolt, only the end part of the bolt is provided with threads (32), and the contact section with the spring (4) is a polished rod (31).
The utility model discloses a radiation detector vibration damper, when fixed plate (1) received external shock or vibration, because compression spring's cushioning effect, the vibration of radiation detector (5) on fly leaf (5) can weaken, plays the damping effect.
Finally, it should be noted that: the foregoing examples are merely illustrative of the principles of the invention and its efficacy, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
