DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, a filter membrane carrier of a cleanliness particle detection instrument comprises a base plate 1, a fixed plate 11 is fixedly connected to the top of the base plate 1, a displacement block 7 is slidably connected inside the fixed plate 11, a placement groove 6 is provided on the top of the displacement block 7, a fixed block 12 is fixedly connected to one side of the fixed plate 11, a slide groove 21 is provided inside the fixed block 12, a limiting component is arranged inside the slide groove 21, a first mounting frame 5 is fixedly connected to one side of the base plate 1, a second mounting frame 10 is fixedly connected to the other side of the base plate 1, a displacement frame 3 is slidably connected between the first mounting frame 5 and the second mounting frame 10, a quartz glass 4 is arranged inside the displacement frame 3, a displacement component is arranged inside the first mounting frame 5 and the second mounting frame 10, a positioning groove 15 is provided inside the fixed plate 11, a positioning block 16 is fixedly connected to the outer side of the displacement block 7, and the outer side of the positioning block 16 is slidably connected to the inner wall of the positioning groove 15.

[0022] First, place the filter membrane with the sample inside the placement groove 6 at the top of the displacement block 7, and then the staff aligns the positioning block 16 with the positioning groove 15, thereby pushing the displacement block 7 to enter the inside of the fixed plate 11, and then the position of the displacement block 7 can be automatically fixed by the limit assembly. This increases the convenience of disassembly and installation of the displacement block 7, saves detection time, and increases detection efficiency. On the other hand, fixing the displacement block 7 avoids the problem of displacement when the filter membrane is subsequently pressed, thereby increasing the stability of the device. After the filter membrane is placed, the displacement assembly is started to drive the displacement frame 3 to move and drive the quartz glass 4 to approach the filter membrane inside the placement groove 6, and then the filter membrane is pressed by the quartz glass 4. This ensures that the sample is evenly distributed on the surface of the filter membrane, making subsequent particle detection more accurate and reliable, and avoiding the problem of manual pressing of the filter membrane, resulting in inconsistent pressure applied by different operators, resulting in instability and reduced reliability of the experimental results.

[0023] like Figure 1-Figure 4 As shown, the displacement assembly includes a reciprocating screw 9, which is rotatably connected to the inside of the second mounting frame 10. A motor 8 is fixedly installed on the top of the second mounting frame 10, and one end of the output shaft of the motor 8 is fixedly connected to one end of the reciprocating screw 9. A threaded groove is provided inside one side of the displacement frame 3 and is threadedly connected to the outer side of the reciprocating screw 9. The displacement assembly also includes a slide rod 13, which is fixedly connected to the inside of the first mounting frame 5, and the inside of a side of the displacement frame 3 away from the reciprocating screw 9 is movably connected to the outer side of the slide rod 13. A displacement groove 2 is penetrated through one side of the first mounting frame 5 and the second mounting frame 10, and the outer side of the displacement frame 3 is slidably connected to the inner wall of the displacement groove 2.

[0024] When pressing, the reciprocating screw 9 is driven to rotate by starting the output shaft of the motor 8, and the displacement frame 3 is driven to move on the outside of the slide bar 13, and then the movement of the displacement frame 3 is guided by the slide bar 13 so that it moves in a vertical state. Then the displacement frame 3 moves to drive the quartz glass 4 toward the filter membrane, and then the displacement frame 3 moves smoothly, and then the pressure applied to the filter membrane is always fixed, thus ensuring the rigor of the detection data.

[0025] like Figure 1-Figure 4As shown, the limit assembly includes a slider 19, which is slidably connected to the inside of the slide groove 21, and a spring 20 is fixedly connected between one side of the slider 19 and the inner wall of the slide groove 21. The limit assembly also includes a clamping block 17, which is slidably connected to the inside of the fixed block 12, and one end of the clamping block 17 is fixedly connected to one side of the slider 19. A clamping groove 14 is provided on the side of the displacement block 7 close to the fixed block 12, and one end of the clamping block 17 extends to the inside of the clamping groove 14. A limit groove 22 is penetrated through one side of the fixed block 12, and a lever 18 is slidably connected to the inside of the limit groove 22, and one end of the lever 18 is fixedly connected to one side of the slider 19.

[0026] When installing the displacement block 7, one side of the displacement block 7 contacts the inclined surface of the block 17, thereby driving the block 17 to move and driving the slider 19 to slide inside the slide groove 21. Then the slider 19 compresses the spring 20, and then the displacement block 7 continues to move. When the slot 14 moves to one side of the block 17, the slider 19 is driven to move under the reaction force of the spring 20 and the block 17 is automatically driven into the slot 14, thereby completing the position fixation of the displacement block 7. Then, when releasing the fixation, the slider 19 is driven to move by toggling the lever 18 and the block 17 is disengaged from the slot 14, thereby releasing the fixation of the displacement block 7. Then, the handle on one side of the displacement block 7 is pulled to drive the filter membrane to disengage from the fixed plate 11.

[0027] The utility model provides a filter membrane carrier for a cleanliness particle detection instrument, and the specific working principle is as follows: first, the filter membrane with the sample is placed inside the placement groove 6 on the top of the displacement block 7, and then the staff aligns the positioning block 16 with the positioning groove 15, thereby pushing the displacement block 7 to enter the inside of the fixed plate 11, and then one side of the displacement block 7 contacts the inclined surface of the card block 17, thereby driving the card block 17 to move and driving the slider 19 to slide inside the slide groove 21, and then the slider 19 compresses the spring 20, and then the displacement block 7 continues to move, and when the card groove 14 moves to one side of the card block 17, the slider 19 is driven to move under the reaction force of the spring 20 and drives the card block 17 to automatically enter the inside of the card groove 14, thereby completing the displacement block 7. The position of block 7 is fixed, and then when pressing, the reciprocating screw 9 is driven to rotate by starting the output shaft of the motor 8, and the displacement frame 3 is driven to move on the outside of the slide bar 13, and then the movement of the displacement frame 3 is guided by the slide bar 13 so that its movement is in a vertical movement state, and then the displacement frame 3 moves to drive the quartz glass 4 to approach the direction of the filter membrane, and then the displacement frame 3 moves smoothly, and then the pressure applied to the filter membrane is always fixed, thus ensuring the rigor of the detection data, and finally when releasing the fixation, the slider 19 is driven to move by toggling the toggle rod 18, and at the same time, the card block 17 is driven to disengage from the inside of the card slot 14, thereby releasing the fixation of the displacement block 7, and then the handle on one side of the displacement block 7 is pulled to drive the filter membrane to disengage from the inside of the fixed plate 11.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
