[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The concave shape of the spring seat of the present invention facilitates the connection of the spring piece with the vertical spring. The spring piece is elastically moved by the elastic force of the vertical spring, so that the end of the spring piece has elastic buffering properties. When the spring piece is placed outside the sliding mouth, the spring piece can be elastically moved upward. When used in conjunction with the slide plate, the spring piece can perform elastic buffering and protection on the structural end face of the positioning connection on the slide plate.

[0016] 2. The present invention uses the elastic force of the transverse spring to pull the bullet seat into the slide, which is convenient for storing the bullet seat when idle. When in use, the bullet seat is pulled outward, and then the vertical spring moves the elastic piece upward, allowing the elastic piece to limit the outward-moving bullet seat and prevent the bullet seat from resetting to the slide, thereby achieving the effect of linkage and coordinated use.

[0017] 3. The present invention rotates the embedded disk by rotating the rotating shaft, so that the disk shaft and the shaft piece on the top of the embedded disk are adjusted accordingly, changing the orientation of the disk shaft and the shaft piece. The disk shaft rotates and the shaft piece is rotated to further change the position of the shaft piece and adjust the orientation of the shaft piece. Then, screws are inserted through the threaded holes in the end walls of the shaft piece to connect and assemble the shaft piece and the positioning structure end, that is, the structure end required to be loaded on the main body. The spring piece, which is elastically elastic, can be elastically moved outward and abut against the side of the positioning structure end to which the shaft piece is assembled, so as to provide buffering protection during assembly.

[0018] 4. The present invention uses a group of three disk shafts and shaft pieces synchronously, which can flexibly adjust the shaft pieces to a suitable position. After flexible direction and position adjustment, they can be adapted for positioning and assembly. Multiple shaft pieces are synchronously positioned, and the folding mechanism assists in positioning, so the body can be assembled, which improves the safety and stability of the body after assembly. At the same time, the slider and the slideway cooperate to adjust the relative position of the slide plate and the heat exchange core. After the slide plate is adjusted, the end screws of the slide plate are tightened to lock the slide plate in position, which facilitates the flexible adjustment of the slide plate and then locking and positioning for use.

[0019] 5. The present invention rotates the connecting bar by rotating the bar shaft, so that the connecting bar rotates toward the inside of the screw seat, and the direction and orientation of the connecting bar are adjusted. Then, the bar hole on the end wall of the connecting bar is used to connect the screw member for positioning and assembling the connecting bar and the bar hole. When in use, the screw seat can also be rotated first to make the screw seat and the slot threaded with each other, and the screw seat can be moved outward appropriately to facilitate the manipulation of the screw seat for adjustment.

A screw 14 is passed through the end, a sliding opening 15 is opened on the side end wall of the slide plate 13, and a spring buffer mechanism 16 is installed on the inner side of the sliding opening 15, a rotating shaft 21 is installed on the middle part of the upper end of the slide plate 13, and a rotating and embedding mechanism 22 is installed on the upper end of the rotating shaft 21, a slot 26 is opened on the right end of the heat exchange core 1, and a screw seat 27 is installed on the inner side of the slot 26, a seat groove 28 is opened on the end wall of the screw seat 27, and a folding mechanism 29 is installed on the inner side of the seat groove 28;

[0030] The elastic buffer mechanism 16 includes a spring seat 17, a vertical spring 18, a spring piece 19 and a transverse spring 20. The upper end of the spring seat 17 is provided with a vertical spring 18, and the upper end of the vertical spring 18 is provided with a spring piece 19. The side end of the spring seat 17 is provided with a transverse spring 20. The spring seat 17 is concave in shape, and the spring seat 17 and the slide 15 are movably connected to each other. The concave shape of the spring seat 17 facilitates the connection of the spring piece 19 with the vertical spring 18. The elastic force of the vertical spring 18 elastically moves the spring piece 19, so that the end of the spring piece 19 has elastic buffering properties. When the spring piece 19 is placed outside the slide 15, the spring piece 19 can be elastically moved upward. When the slide plate 13 is used, the spring piece 19 performs elastic buffering and protection on the structural end surface of the positioning connection on the slide plate 13.

[0031] The spring seat 17 forms an elastic structure with the slide plate 13 through the transverse spring 20, and the spring seat 17 forms an elastic structure with the spring plate 19 through the vertical spring 18. The elastic force of the transverse spring 20 pulls the spring seat 17 into the slide 15, which is convenient for storing the spring seat 17 when not in use. When in use, the spring seat 17 is pulled outward, and then the vertical spring 18 elastically moves the spring plate 19 upward, so that the spring plate 19 limits the outward-moving spring seat 17 and prevents the spring seat 17 from returning to the slide 15, achieving the effect of linkage and coordinated use.

[0032] The rotating and embedding mechanism 22 includes an embedding plate 23, a disk shaft 24 and a shaft piece 25. The end of the embedding plate 23 is provided with a disk shaft 24, and the side end of the disk shaft 24 is installed with a shaft piece 25. The embedding plate 23 forms a rotating structure with the slide plate 13 through the rotating shaft 21, and the embedding plate 23 forms a rotating structure through the disk shaft 24 and the shaft piece 25. When the rotating shaft 21 rotates, the embedding plate 23 is rotated, so that the disk shaft 24 and the shaft piece 25 at the top of the embedding plate 23 are adjusted accordingly, thereby changing the orientation of the disk shaft 24 and the shaft piece 25. Then, the disk shaft 24 rotates, rotating the shaft piece 25, further changing the position of the shaft piece 25, adjusting the orientation of the shaft piece 25, and then inserting a screw through the threaded hole on the end wall of the shaft piece 25 to connect and assemble the shaft piece 25 and the positioning structure end, that is, the structure end required to be loaded on the body. The elastic piece 19, which is elastically elastic, can be elastically moved outward and abut against the side of the positioning structure end assembled with the shaft piece 25, so as to provide buffer protection during assembly.

[0033] The disc shaft 24 and the shaft piece 25 are distributed in a ring shape about the center of the embedded disc 23. At the same time, the slide 13 forms a sliding structure with the heat exchange core 1 through the slider 12 and the slideway 11. By using a group of three disc shafts 24 and shaft pieces 25 synchronously, the shaft piece 25 can be flexibly adjusted to a suitable position. After flexible direction and position adjustment, it can be adapted for positioning and assembly. Multiple shaft pieces 25 are synchronously positioned, and the folding mechanism 29 assists in positioning, so that the body can be assembled, thereby improving the safety and stability of the body after assembly. At the same time, the slider 12 and the slideway 11 cooperate to adjust the relative position of the slide 13 and the heat exchange core 1. After the slide 13 is adjusted, the screw 14 at the end of the slide 13 is tightened to lock the slide 13 in position, so that the slide 13 can be flexibly adjusted and locked for use.

[0034] The folding mechanism 29 includes a connecting rod 30, a rod shaft 31 and a rod hole 32. The side end of the connecting rod 30 is provided with a rod shaft 31, and the end wall of the connecting rod 30 is provided with a rod hole 32. The connecting rod 30 forms a rotating structure with the screw seat 27 through the rod shaft 31, and the screw seat 27 is threadedly connected to the heat exchange core 1 through the slot 26. At the same time, the discharge chamber 3 and the condensate drain port 5 are connected. By rotating the rod shaft 31, the connecting rod 30 is rotated so that the connecting rod 30 rotates toward the inside of the screw seat 27 to adjust the direction and orientation of the connecting rod 30. Then, the rod hole 32 on the end wall of the connecting rod 30 is used to penetrate the screw for positioning and assembly of the connecting rod 30 and the rod hole 32. When in use, the screw seat 27 can be rotated first so that the screw seat 27 and the slot 26 are threadedly driven with each other, and the screw seat 27 is appropriately moved outward to facilitate the manipulation of the screw seat 27 for adjustment. When in use, high-temperature and high-humidity compressed air enters through the air inlet 8, flows downward through the heat exchange chamber 9, is separated from gas and water through the return plate 10, and the water is discharged through the condensation drain port 5. When the high-temperature and high-humidity compressed air passes through the bottom of the heat exchange chamber 9, it is cooled down for the second time through the condensation channel 6 that adds refrigerant through the refrigerant port 7. The high-temperature and high-humidity compressed air flows into the discharge chamber 3 from the bottom of the heat exchange chamber 9, is separated from gas and liquid again through the separation screen 4, and then is discharged from the air outlet 2 through the top of the discharge chamber 3. The design of the two condensation drain ports 5, when the heat exchange core 1 is assembled vertically, the water is discharged from the condensation drain port 5 at the bottom of the heat exchange core 1, and when it is assembled horizontally, the water is discharged from the condensation drain port 5 at the lower right end of the heat exchange core 1, which is convenient for the heat exchange core 1 to be assembled and used vertically or horizontally.

[0035] In summary, the heat exchanger of the cold dryer is convenient to assemble. When in use, the concave shape of the spring seat 17 is conveniently matched with the vertical spring 18 to connect the spring piece 19. The spring piece 19 is elastically moved by the elastic force of the vertical spring 18, so that the end of the spring piece 19 has elastic buffering properties. When the spring piece 19 is placed outside the sliding port 15, the spring piece 19 can be elastically moved upward. When used in conjunction with the slide plate 13, the spring piece 19 performs elastic buffering and protection on the structural end face of the positioning connection on the slide plate 13. The elastic force of the transverse spring 20 is used to pull the spring seat 17 into the sliding port 15, which is convenient for storing the spring seat 17 when idle. When in use, the spring seat 17 is pulled outward, and then the vertical spring 18 elastically moves the spring piece 19 upward, so that the spring piece 19 limits the outward-moving spring seat 17, preventing the spring seat 17 from resetting to the sliding port 15, playing a role. The effect of linkage and coordinated use is that the rotating shaft 21 rotates and the embedded disk 23 is rotated, so that the disk shaft 24 and the shaft piece 25 at the top of the embedded disk 23 are adjusted accordingly, and the orientation of the disk shaft 24 and the shaft piece 25 is changed. Then, the disk shaft 24 rotates and the shaft piece 25 is rotated, and the position of the shaft piece 25 is further changed. The orientation of the shaft piece 25 is adjusted, and then the screw is passed through the threaded hole on the end wall of the shaft piece 25 to connect and assemble the shaft piece 25 and the positioning structure end, that is, the structural end required to be loaded on the body. The elastic spring piece 19 that is elastically elastic can be elastically moved outward and abuts against the positioning structure end side assembled by the shaft piece 25, so that buffer protection is provided during the assembly. By using a group of three disk shafts 24 and shaft pieces 25 synchronously, the shaft piece 25 can be flexibly adjusted to a suitable position for flexible adjustment. After the direction and position are adjusted, the adapter is positioned and assembled, and the multiple shaft pieces 25 are positioned synchronously, and the folding mechanism 29 is assisted in positioning, so that the body can be assembled, thereby improving the safety and stability of the body after assembly. At the same time, the slider 12 and the slide 11 cooperate to adjust the relative position of the slide 13 and the heat exchange core 1. After the slide 13 is adjusted, the screw 14 at the end of the slide 13 is tightened to lock the slide 13 in position, which is convenient for the flexible adjustment of the slide 13. It is locked and positioned for use, and the connecting bar 30 is rotated by rotating the bar shaft 31 so that the connecting bar 30 rotates toward the inside of the screw seat 27 to adjust the direction and orientation of the connecting bar 30. Then, the bar hole 32 on the end wall of the connecting bar 30 is used to penetrate the screw for positioning and installation of the connecting bar 30 and the bar hole 32. When in use, you can also rotate the screw seat 27 first, so that the screw seat 27 and the slot 26 are threaded with each other, and the screw seat 27 is appropriately moved outward to facilitate the operation of the screw seat 27 for adjustment. When in use, the high-temperature and high-humidity compressed air enters through the air inlet 8, flows downward through the heat exchange chamber 9, and is separated into gas and water through the return plate 10. The water is discharged through the condensation drain port 5. When the high-temperature and high-humidity compressed air passes through the bottom of the heat exchange chamber 9, it is cooled for the second time through the condensation channel 6 that adds refrigerant through the refrigerant port 7. The high-temperature and high-humidity compressed air flows into the discharge chamber 3 from the bottom of the heat exchange chamber 9, is separated into gas and liquid again through the separation screen 4, and then is discharged from the air outlet 2 through the top of the discharge chamber 3. The design of the two condensation drain ports 5, when the heat exchange core 1 is assembled vertically,The water is discharged from the condensation drain port 5 at the bottom of the heat exchange core 1. When assembled horizontally, the water is discharged from the condensation drain port 5 at the lower right end of the heat exchange core 1, which is convenient for assembling and using the heat exchange core 1 vertically or horizontally.
