[0020] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation mode of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0021] Refer to Figures 1-4 , which is the first embodiment of the present utility model, and provides an installation mechanism based on a photomultiplier tube. This installation mechanism based on a photomultiplier tube includes a photomultiplier tube socket 1, a power supply base 2 installed inside the photomultiplier tube socket 1, a photomultiplier tube sleeve 3 installed on the top of the photomultiplier tube socket 1, the power supply base 2 is located inside the photomultiplier tube sleeve 3, a photomultiplier tube 4 located on the top of the power supply base 2, the photomultiplier tube 4 is located inside the photomultiplier tube sleeve 3. A groove 21 is opened inside the power supply base 2, an elastic piece 22 is installed inside the groove 21, both sides of the top of the elastic piece 22 are fixedly connected with a movable piece 23, and one end of the movable piece 23 and located on the top of the elastic piece 22 is fixedly connected with a bump 24. The bump 24 is arc-shaped, and the elastic piece 22, the movable piece 23, and the bump 24 are an integrated structure;

[0022] The elastic piece 22 is an elastic metal piece, which can form a certain pressure with the connecting block 52, so as to achieve connection and provide a certain shockproof and vibration-proof performance. The bottom of the elastic piece 22 is fixedly connected with the inside of the groove 21. Cavities for the movement of the movable piece 23 are opened on both sides of the inside of the groove 21 and on both sides of the movable piece 23, which can prevent the movable piece 23 from getting stuck when being squeezed or stretched. The inside of the elastic piece 22 is a hollow structure, which is convenient for connecting with the connecting block 52 and at the same time convenient for the installation of the photomultiplier tube 4.

[0023] A collar 5 is fixedly connected to the outer surface of the photomultiplier tube 4. The collar 5 is located at the bottom of the photomultiplier tube 4. The setting of the collar 5 can facilitate the connection of the photomultiplier tube 4 and at the same time avoid the problem of residual fingerprints on the surface of the photomultiplier tube 4, thereby affecting its performance.

[0024] The bottom of the collar 5 is fixedly connected with a connecting plate 51, the bottom of the connecting plate 51 is fixedly connected with a connecting block 52, and the connecting block 52 is cylindrical in shape, which is convenient for connecting with the elastic piece 22.

[0025] The connecting block 52 extends into the inside of the groove 21 and is located inside the elastic piece 22 and is movably connected thereto. An arc-shaped groove is opened at the top of the connecting block 52 and at the bottom of the connecting plate 51, that is, at the connection part between the two. The bump 24 is located inside the arc-shaped groove, which is convenient for the connection between the two and ensures the stability of their connection.

[0026] Inside the photomultiplier tube socket 1, there is a screw 6. The screw 6 penetrates through the power supply base 2 and extends to the bottom of the photomultiplier tube sleeve 3 and is threadedly connected thereto. That is, the photomultiplier tube socket 1, the power supply base 2, and the photomultiplier tube sleeve 3 are connected by the screw 6. In this way, the three can be of a detachable style, thus avoiding the problem of increasing the maintenance cost. At the same time, the three are connected by the screw 6, saving resources.

[0027] During use, by connecting the photomultiplier tube socket 1, the power supply base 2, and the photomultiplier tube sleeve 3 with the screw 6, the cost can be saved, and the operation is simple. At the same time, setting the three to be detachable can avoid the phenomenon of needing to replace multiple sets of structures when replacing a single set of structures, further reducing the cost during replacement and maintenance;

[0028] At the same time, when installing the photomultiplier tube 4, only need to install it on the top of the power supply base 2, make the bottom of the connecting block 52 contact the inner side of the convex block 24, and at the same time apply pressure to make the connecting block 52 squeeze the two sides of the convex block 24, so that the convex block 24 pushes the two movable pieces 23 to move towards the inside of the cavity, that is, the two convex blocks 24 move away from each other until the connecting block 52 is completely located inside the elastic piece 22. At this time, the pressure of the elastic piece 22 is cancelled, and it will drive the two movable pieces 23 and the convex block 24 to move closer to each other until they fit the arc grooves on both sides of the connecting block 52, and the installation operation can be completed, thus ensuring the stability when the two are connected;

[0029] Through the setting of the elastic piece 22 and the connecting block 52, the vibration between the photomultiplier tube 4 and the power supply base 2 can be reduced by the elasticity of the elastic piece 22 itself, thereby improving the seismic performance of the system. At the same time, compared with bolt connection, the step of turning the screwdriver is saved, so that the installation and disassembly are more simple. At the same time, in cooperation with the use of the screw 6, the waste of resources can be avoided, and the maintenance cost is reduced.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
