[0033] First, after installing the heat exchange core 3 into the switch, the personnel can control the sealing mechanism 11 to seal the gap at the connection between the heat exchange core 3 and the switch, thereby improving the sealing performance of the equipment during use and enhancing the practicability of the equipment. Thereafter, the personnel can control the locking mechanism 12 to lock the sealing mechanism 11, thereby preventing the sealing mechanism 11 from moving during use of the equipment, thereby affecting the sealing performance of the equipment. Thereafter, the auxiliary mechanism 10 can be controlled to limit the upper part of the sealing mechanism 11, thereby preventing accidental touch during use by personnel, and at the same time preventing the sealing mechanism 11 from loosening during use of the equipment. The locking mechanism 12 and the auxiliary mechanism 10 can effectively prevent the sealing mechanism 11 from loosening, thereby affecting the normal use of the equipment. At the same time, when personnel need to take out the heat exchange core 3, the heat-resistant handle 6 also makes it more convenient for personnel to take it out.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the sealing mechanism 11 includes a transmission anti-skid rotating wheel 1101, a vertical transmission rod 1102, a cross transmission plate 1103, a transmission pull rod 1104, a parallel push plate 1105, a sealing rubber pad 1106, a limiting rotating rod 1107 and a reset spring 1108.

[0035] By rotating the transmission anti-skid wheel 1101, the transmission anti-skid wheel 1101 will drive the cross transmission plate 1103 to rotate through the vertical transmission rod 1102. At this time, the cross transmission plate 1103 will push the parallel push plate 1105 through the transmission pull rod 1104 during rotation, so that the parallel push plates 1105 on all sides push the sealing rubber pad 1106 to stick out from the through groove 7, thereby strengthening the sealing of the joint between the heat exchange core 3 and the switch. At the same time, after the sealing state is released, the reset spring 1108 will drive the sealing rubber pad 1106 to reset, so as to facilitate subsequent use. At the same time, the upper and lower layers of sealing rubber pads 1106 can greatly improve the sealing, thereby improving the practicability of the equipment.

[0036] like Figure 3 , Figure 5 , Figure 8 and Figure 7 As shown, the locking mechanism 12 includes a vertical pressure rod 1201, a transmission bottom rod 1202, a connecting rod 1203, a Y-shaped card plate 1204 and a second return spring 1205. The bottom end of the vertical pressure rod 1201 is rotatably connected to the top end of the transmission bottom rod 1202. A plurality of connecting rods 1203 are provided, and the top end of the connecting rod 1203 is hinged to the inside of the transmission bottom rod 1202, and the bottom end of the connecting rod 1203 is hinged to one side of the Y-shaped card plate 1204. The top end of the second return spring 1205 is fixedly connected to the bottom end of the transmission bottom rod 1202, and The bottom end of the reset spring 1205 is fixedly connected to the inner bottom end of the vertical transmission rod 1102, the other side of the Y-shaped clamping plate 1204 is movably connected to the middle section of the limiting rotating rod 1107, the bottom end of the vertical pressure rod 1201 is slidably connected to the inside of the limiting groove, the top of the vertical pressure rod 1201 extends to the outside of the top of the vertical transmission rod 1102, the Y-shaped clamping plate 1204 is movably connected to the inside of the cross transmission plate 1103, and a through groove 9 is opened at the bottom end of the vertical transmission rod 1102, and the connecting rod 1203 is movably connected to the inside of the through groove 9.

[0037] After the operation of the control sealing mechanism 11 is completed, the vertical pressure rod 1201 can be pressed. At this time, the vertical pressure rod 1201 will press the transmission bottom rod 1202, so that under the action of the transmission bottom rod 1202, the connecting rod 1203 will push the surrounding Y-shaped card plates 1204 to expand outward. At this time, one side of the Y-shaped card plate 1204 will jam the middle section of the limit rotating rod 1107. At this time, the limit rotating rod 1107 cannot rotate, thereby ensuring that the sealing rubber pad 1106 will not loosen during use. When the vertical pressure rod 1201 is pressed to the bottom, the vertical pressure rod 1201 can be slightly rotated. At this time, the bottom end of the vertical pressure rod 1201 will form a limit between the limit groove. When the use is finished, the vertical pressure rod 1201 is rotated in the opposite direction and the reset spring 2 1205 will reset the transmission bottom rod 1202. Through this locking mechanism 12, the sealing rubber pad 1106 can be effectively prevented from loosening, reducing the difficulty of personnel operation.

[0038] like Figure 3 and Figure 6 As shown, the auxiliary mechanism 10 includes a fixed shell 1001, a transmission screw 1002, a movable pressure plate 1003, a movable rod 1004, a limit adsorption magnetic plate 1005, an auxiliary slider 1006 and a parallel slide rail 1007, the top of the transmission screw 1002 is rotatably connected to the middle section of the movable pressure plate 1003, the bottom end of the transmission screw 1002 extends to the inside of the fixed shell 1001 and is rotatably connected to the fixed shell 1001, both sides of the bottom end of the movable pressure plate 1003 extend to the inside of the fixed shell 1001 and are hinged to one end of the movable rod 1004, and the other end of the movable rod 1004 is hinged to the limit adsorption magnetic plate 1005. The outer wall of the magnetic plate 1005 is provided with two parallel slide rails 1007 which are symmetrical on the left and right, and the auxiliary slider 1006 is slidably connected to the top of the parallel slide rail 1007, and the top of the auxiliary slider 1006 is fixedly connected to the bottom end of the limiting adsorption magnetic plate 1005, and the limiting adsorption magnetic plate 1005 is provided with two positive and negative poles, the fixed shell 1001 is fixedly connected to the top of the mounting top plate 4, the limiting adsorption magnetic plate 1005 is movably connected to the outside of the transmission anti-slip wheel 1101, the parallel slide rail 1007 is fixedly connected to the top of the mounting top plate 4, and the movable rod 1004 is movably connected to the inside of the fixed shell 1001.

[0039] When the sealing mechanism 11 and the locking mechanism 12 are operated, the transmission screw 1002 can be rotated. When the transmission screw 1002 rotates, the movable pressure plate 1003 is driven to move downward, thereby driving the movable rod 1004 through the bottom end of the movable pressure plate 1003 to push the limiting adsorption magnetic plates 1005 closer to each other, so that the limiting adsorption magnetic plates 1005 are adsorbed on each other. At this time, the limiting adsorption magnetic plate 1005 will wrap the transmission anti-slip wheel 1101 inside, so as to prevent accidental touch during use, thereby loosening the sealing rubber pad 1106, and also prevent loosening due to vibration.

[0040] Here’s how it works:

[0041] When in use, first, after installing the heat exchange core 3 into the switch, the personnel can rotate the transmission anti-skid wheel 1101, and the transmission anti-skid wheel 1101 will drive the cross transmission plate 1103 to rotate through the vertical transmission rod 1102. At this time, the cross transmission plate 1103 will push the parallel push plate 1105 through the transmission pull rod 1104 during rotation, so that the parallel push plates 1105 on all sides push the sealing rubber pad 1106 to protrude from the inside of the through groove 7, thereby strengthening the sealing of the joint between the heat exchange core 3 and the switch. At the same time, after the sealing state is released, the reset spring 1108 will drive the sealing rubber pad 1106 to reset. The sealing rubber pads 1106 are deformed when squeezed, so that the sealing rubber pads 1106 on the upper and lower sides can fit each other after squeezing, thereby increasing the sealing area, filling the gap and preventing air leakage. After the control sealing mechanism 11 is completed, the vertical pressure rod 1201 can be pressed. At this time, the vertical pressure rod 1201 will press the transmission bottom rod 1202, so that the surrounding Y-shaped cards are pushed through the connecting rod 1203 under the action of the transmission bottom rod 1202. When the plate 1204 expands outward, one side of the Y-shaped card plate 1204 will clamp the middle section of the limit rotating rod 1107, and the limit rotating rod 1107 cannot rotate at this time, thereby ensuring that the sealing rubber pad 1106 will not be loose during use. When the vertical pressure rod 1201 is pressed to the bottom, the vertical pressure rod 1201 can be slightly rotated. At this time, the bottom end of the vertical pressure rod 1201 will form a limit between the limit groove. When the use is finished, the vertical pressure rod 1201 is rotated in the opposite direction and the reset spring 1205 will reset the transmission bottom rod 1202. This locking mechanism 12 can effectively prevent the sealing rubber pad 1106 from loosening. , reducing the difficulty of operation for personnel. After the sealing mechanism 11 and the locking mechanism 12 are operated, the transmission screw 1002 can be rotated. When the transmission screw 1002 rotates, it will drive the movable pressure plate 1003 to move downward, thereby driving the movable rod 1004 through the bottom end of the movable pressure plate 1003 to push the limiting adsorption magnetic plates 1005 closer to each other, so that the limiting adsorption magnetic plates 1005 are adsorbed on each other. At this time, the limiting adsorption magnetic plate 1005 will wrap the transmission anti-slip wheel 1101 inside, so as to prevent accidental touch during use, thereby loosening the sealing rubber pad 1106, and also prevent loosening caused by vibration.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
