Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a compressor for producing liquid nitrogen, including compressor body 1, compressor body 1's bottom fixed mounting has base 2, the sliding sleeve is equipped with install box 3 on base 2, the bottom four corners of install box 3 all rotates and installs universal wheel 16, be equipped with buffering pressure regulating mechanism in install box 3, buffering pressure regulating mechanism is including seting up the first groove in base 2 bottom, sliding sleeve is equipped with pressure regulating plate 5 in install box 3, fixed mounting has a plurality of buffer spring 4 between the top inner wall of pressure regulating plate 5's top and first groove, the bottom fixed mounting of pressure regulating plate 5 has trapezoidal block 6, trapezoidal block 6's both sides all set up to the inclined plane, installation box 3's bottom inner wall has seted up mounting groove 7, trapezoidal block 6's bottom extends to in mounting groove 7, all rotate to install screw rod 8 on the inner wall of mounting groove 7, the one end that two screw rods 8 are close to each other collides with each other, screw rod 8's screw thread revolves direction is opposite, fixed mounting has 15 on the bottom inner wall of

mounting groove

7, 15 rotates on two screw rods 8, one side bottom of installation box 3, the installation box 3 is fixed mounting groove 3, the fixed mounting groove 3 is equipped with the fixed mounting groove 3, the fixed mounting groove is equipped with the fixed mounting groove 3, the fixed mounting groove is equipped with the fixed mounting groove of the fixed mounting groove 3, the fixed mounting groove of the fixed mounting groove, the fixed mounting groove of the fixed mounting groove 3, the fixed mounting groove of the fixed mounting groove 3, the fixed mounting groove of the fixed mounting groove, the fixed mounting groove of the fixed mounting groove 3, the fixed mounting groove of the fixed mounting groove.

The working principle is as follows: when the compressor is used, when the compressor body 1 works and generates a large vibration force, the vibration force drives the base 2 to move downwards through the compressor body 1, the base 2 compresses the buffer spring 4 while moving downwards, the compressor body 1 is buffered under the elastic force action of the buffer spring 4, the phenomenon that parts in the compressor body 1 are damaged due to the fact that the compressor body 1 directly collides with the ground is avoided, the purpose of buffer protection of the compressor body 1 is achieved, and the four universal wheels 16 are arranged to facilitate the compressor body 1 to move to a designated position;

when the elasticity of the buffer spring 4 is soft, the driving motor 12 is started in the forward direction, the output shaft of the driving motor 12 drives one screw 8 of the two screws 8 to rotate, one screw 8 drives the other screw 8 fixedly connected with the screw 8 to rotate, under the action of the threaded hole formed in one side of the L-shaped rod 9, the screw 8 drives the corresponding L-shaped rod 9 to move while rotating, the two L-shaped rods 9 respectively move in the mutually approaching direction on the corresponding L-shaped positioning rods 10 and drive the balls 14 to extrude the side walls of the ball grooves 13, under the action of the extrusion force of the two balls 14, the trapezoidal block 6 moves upwards, the trapezoidal block 6 drives the pressure adjusting plate 5 to move upwards, the pressure adjusting plate 5 drives the four first positioning rods 11 to respectively slide upwards in the corresponding first rectangular holes, the pressure adjusting plate 5 compresses the buffer spring 4 while moving upwards, so that the buffer spring 4 is slightly compressed or semi-compressed before being buffered, the compression stroke of the buffer spring 4 is shortened, the damping spring 4 in the compression stroke obviously increases the elasticity adjustment range of the buffer spring, and the buffer spring can be adjusted effectively, and the shock impact force of the buffer spring can be reduced.
