DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 The utility model provides a technical solution: a wax thermal valve core assembly tool, including a lower fixed plate 10, a polished rod 7 is correspondingly installed on the top of the lower fixed plate 10, a sliding sleeve 5 is slidably sleeved on the outer wall of the polished rod 7, and the inner walls of both sides of the sliding sleeve 5 are correspondingly fixedly installed with side centering rods 6 by welding, and the tops of the two sliding sleeves 5 are fixedly connected with a middle movable plate 3 by bolts. The middle movable plate 3 can slide up and down, and the valve housing is installed to the middle when it moves upward, and the position of the valve housing is fixed when it moves downward;

[0019] The top of the polished rod 7 is fixedly connected to the upper fixing plate 2 by welding, and the top of the upper fixing plate 2 is fixedly installed with a telescopic cylinder 1 by bolts. The bottom output end of the telescopic cylinder 1 is connected to the lower push rod 4. When the valve core needs to be loaded, the telescopic cylinder 1 is operated to stretch the lower push rod 4, squeezing the valve core into the appropriate position of the valve housing to realize the assembly of the valve core;

[0020] A lower fixed shell 9 is installed at the top center of the lower fixed plate 10. The lower fixed shell 9 is divided into two upper and lower chambers. A movable column 8 is slidably installed inside the upper chamber. A contact block 11 is fixedly installed on the top of the movable column 8. The upper and lower chambers of the lower fixed shell 9 are connected to each other.

[0021] The top of the lower fixed shell 9 is connected to a connecting sleeve 12, and the outer movable sleeve of the movable column 8 is connected to a spring 13. The two ends of the spring 13 are in contact with the contact block 11 and the connecting sleeve 12 respectively. When the valve housing is sleeved on the outside of the movable column 8, due to gravity and the thrust from above, the movable column 8 will move downward, causing the spring 13 to contract. When the thrust is lost, the spring 13 stretches, causing the movable column 8 to return to its original position.

[0022] An elastic airbag 14 is provided inside the lower chamber of the lower fixed shell 9. Rubber hoses 15 are connected to the two ends of the elastic airbag 14. When the movable column 8 is pressed downward, the air in the upper chamber is squeezed downward, causing the elastic airbag 14 to contract, and the air inside the elastic airbag 14 is squeezed into the rubber hose 15. When the elastic airbag 14 is restored, it expands.

[0023] An elastic top block 16 is slidably sleeved on one end of the side centering rod 6, and a second spring 17 is connected between the elastic top block 16 and the side centering rod 6. The inner wall of the elastic top block 16 is through-connected with one end of the rubber hose 15. Since the elastic top block 16 is in a retracted state at the beginning, it opens outward after being inflated through the rubber hose 15, centering the valve housing and squeezing it to prevent it from deflecting. The second spring 17 is used to return the elastic top block 16 to its original position.
