[0002] "Pumping equipment" has a water inlet and a water pressure inlet. The water inlet is used to suck liquid into the pump body, and the high-speed operation of the impeller converts mechanical energy into kinetic energy and potential energy of the liquid, and presses the liquid out of the water pressure inlet. Therefore, the pump needs to extract the medium first, and then provide pressure to the medium. The two are combined to form a pump.

[0003] During the installation of pump equipment, it is often encountered that the installation space is limited, resulting in an inclination angle between the two connection ports. At this time, it is difficult to install the rigid connection joints between them. At this time, flexible connection joints are needed for adaptation. However, during actual installation and use, the joints required for installation are usually flange structures, which require bolt and nut fasteners to be installed at the setting interface. The high-frequency vibration generated during the operation of the pump equipment can easily cause the nuts in the fasteners required for the connection to reverse and loosen over time, affecting the stable performance of the pump equipment during operation.

[0016] See also Figure 1-4The utility model provides a technical solution: a shockproof joint for pumping equipment, including an interface 1, which is a connection interface for two pipes to be connected to the pumping equipment, a first flange 2 is fixedly connected to one side of the interface 1, and a second flange 3 is pressed against the other side of the first flange 2, and a plurality of bolts 4 are inserted into the outer surface of the first flange 2 in an annular shape and at equal intervals, and the number of bolts 4 is at least four and evenly distributed, and a nut 5 is threadedly connected to the outer wall of the bolt 4, and the nut 5 is pressed against the contact surface of the second flange 3, and a connecting pipe 6 is arranged between the two second flanges 3, and the connecting pipe 6 is a double-layer structure, which is a corrugated pipe and a metal mesh cover from the inside to the outside, and has a certain flexibility and can be It is suitable for use when there is an inclination angle between the two ports to be connected due to the limitation of the installation space. Both ends of the outer wall of the connecting pipe 6 are fixedly sleeved with protective rings 7. The protective ring 7 is fixedly connected to the contact surface of the second flange 3. The outer side of the protective ring 7 is provided with a shockproof unit 8. The shockproof unit 8 includes a collar 801, a slide bar 802, a cross bar 803, an angular hole 804, a spring 805, a sleeve 806, a screw 807 and a hexagonal groove block 808. The two collars 801 are respectively sleeved on the outer walls of the two protective rings 7. The inner wall of the collar 801 is gap-matched with the outer wall of the protective ring 7. The collar 801 is connected to the protective ring 7 by sliding and clamping through the slide bar 802. The slide bar 802 The sleeve ring 801 can be limited in sliding, so that the sleeve ring 801 can slide left and right but cannot move up and down or forward and backward. The slide bar 802 is fixedly connected to the contact surface of the guard ring 7. One side surface of the sleeve ring 801 is annular and equidistantly inserted with multiple cross bars 803. The cross bars 803 penetrate the sleeve ring 801. The cross bars 803 are rotatably connected to the sleeve ring 801 through a ball bearing. The inner wall of the cross bar 803 is provided with an angular hole 804. The angular hole 804 is a hexagonal hole, which can facilitate the insertion of an external hexagonal wrench to fully apply force to the cross bar 803 to rotate. The outer wall of the cross bar 803 is fixedly sleeved with a spring 805. The coefficient of the spring 805 is 20-50N / CM. The outer ring of the mainspring 805 is fixedly connected with a sleeve 806, and the sleeve 806 is fixedly connected to the contact surface of the collar 801. The outer wall of the collar 801 is annularly equidistantly threaded with multiple screws 807, and the screws 807 penetrate a part of the collar 801 and are tightly pressed against the outer wall of the crossbar 803. The end of the crossbar 803 facing the nut 5 is fixedly connected with a hexagonal groove block 808, and the hexagonal groove block 808 can be connected with the nut 5 by clamping. The bolt 4 penetrates the second flange 3 through the soft tube 9, and the soft tube 9 is fixedly connected to the contact surface of the second flange 3. The soft tube 9 is made of rubber material and has a certain flexibility, which can buffer and reduce the vibration intensity transmitted and filtered by the bolt 4.

[0017] During the use of the anti-vibration joint of the pumping equipment, the operator first fits the second flange 3 with the second flange 2, and then uses the bolts 4 and nuts 5 to connect the first flange 2 with the third flange 3, so that the two interfaces 1 of the pumping equipment can be docked through the connecting pipe 6, so that the medium between the two joints 1 can flow through the connecting pipe 6. During the installation operation, after the nut 5 is tightened, the operator rotates the cross bar 803 counterclockwise to make the spring 805 fully compress and deform for multiple turns, and align the hexagonal groove of the hexagonal groove block 808 with the hexagonal groove on the outside of the nut 5, and then rotates the screw 807 clockwise to align with the cross bar. 803 are pressed against each other, and then the operator slides the collar 801 in the direction of the nut 5, so that the multiple hexagonal groove blocks 808 are mounted on the upper outside of the multiple nuts 5, and then the screw 807 is rotated counterclockwise, and the inner end of the screw 807 is separated from the cross bar 803. In addition, the spring 805 is rebounded, so that the cross bar 803 and the hexagonal groove block 808 generate a torsion in the clockwise direction. Due to the clamping relationship between the hexagonal groove block 808 and the nut 5, the nut 5 can then generate a force required for clockwise rotation and tightening. In this way, when the pumping equipment is vibrated during operation, the tightening nut 5 is not easy to reverse and loosen, which is convenient for the stable operation of the pumping equipment.
