[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0023] See also Figure 1-2 As shown, this embodiment is a shock-absorbing structure of an assembled filter and pump core, including:
[0024] The shock-absorbing part includes a shock-absorbing belt 21, a shock-absorbing pad 22, and a hydraulic shock absorber 23. The shock-absorbing pad 22 is fixedly connected to the lower end of the shock-absorbing belt 21, and the hydraulic shock absorber 23 is symmetrically arranged and connected to the lower end of the shock-absorbing pad 22. The lower end of the shock-absorbing pad 22 is symmetrically provided with notches, and the upper end of the hydraulic shock absorber 23 is sleeved and connected to the notches;
[0025] The shock-absorbing belt 21 and the shock-absorbing pad 22 are used in conjunction with the hydraulic shock absorber 23 to achieve the purpose of shock absorption, which helps to reduce noise and improve the use effect. The principle of the hydraulic shock absorber 23 is to achieve shock absorption through the squeezing force between the piston rod and the oil in the oil chamber and the internal molecular force between the oil. The notch is fixed to the upper part of the hydraulic shock absorber 23, which facilitates disassembly and maintenance.
[0026] The outer surface of the output end of the hydraulic shock absorber 23 is wound with a spiral shock-absorbing spring;
[0027] The spiral shock-absorbing spring is used in conjunction with the hydraulic shock absorber 23 to achieve the purpose of shock absorption;
[0028] The shock-absorbing belt 21 is arranged and connected to the pump body, which includes a metal shell 11, a pump core 12, and a filter 13. The pump core 12 is fixedly connected to the middle part of the metal shell 11, and the filter 13 is fixedly connected to the outer surface of the pump core 12. The lower end of the filter 13 is fixed to the upper end of the shock-absorbing belt 21.
[0029] The lower end of the hydraulic shock absorber 23 is fixedly connected to a movable plate 24, and the end of the movable plate 24 is buckled and connected to a threaded column 25;
[0030] The movable plate 24 is used in conjunction with the threaded column 25 to perform structural installation on the lower part of the hydraulic shock absorber 23. The threaded installation method can meet the requirements of the disassembly and assembly of the hydraulic shock absorber 23.
[0031] A through opening 26 is formed through the lower end of the metal shell 11, and the movable plate 24 is arranged in the through opening 26;
[0032] The through opening 26 satisfies the space required for disassembly and assembly of the hydraulic shock absorber 23;
[0033] The two side walls of the through opening 26 are provided with movable openings 27 , and one end of the threaded column 25 is threadedly extended into the inner wall of the movable opening 27 ;
[0034] The movable opening 27 is used to structurally mount the threaded column 25 and meet the rotation space requirements;
[0035] Working principle: A shock-absorbing belt 21 is arranged at the lower end of the filter 13, and a shock-absorbing pad 22 is arranged at the lower end of the shock-absorbing belt 21;
[0036] At this time, a hydraulic shock absorber 23 needs to be installed on the lower end of the shock absorbing pad 22. A rotational force is applied to the hydraulic shock absorber 23. Under the rotation of the threaded column 25, the rotation angle of the hydraulic shock absorber 23 is adjusted until the upper part of the hydraulic shock absorber 23 is engaged with the notch. The upper part of the hydraulic shock absorber 23 is fixed, and the threaded column 25 ensures that the lower part of the hydraulic shock absorber 23 is fixed. The shock absorbing belt 21 and the shock absorbing pad 22 are used in conjunction with the hydraulic shock absorber 23 to meet the shock absorption requirements.
[0037] This solution helps to reduce noise, improve the use effect, and is conducive to the structural disassembly and assembly of the hydraulic shock absorber 23, thereby improving the use effect.
