[0038] Reference Figure 1-2 , this embodiment provides a thermal control instrument antifreeze device.

[0039] The thermal control instrument antifreeze device comprises a protection mechanism 100 .

[0040] Specifically, the protection mechanism 100 includes a protective shell 101 for placing a thermal control instrument therein, a front cover 102 for sealing is hingedly installed on the front of the protective shell 101, and a heating plate 103 for heating and protecting the instrument is installed on the inner side of the front cover 102.

[0042] Example 2

[0043] Reference Figure 1-7 This embodiment provides a thermal control instrument antifreeze device

[0044] The thermal control instrument antifreeze device further includes a connecting mechanism 200 .

[0045] Specifically, the connection mechanism 200 includes a housing 201 disposed on the surface of the front cover plate 102, an inflatable member 202 is installed inside the housing 201, an inflating member 203 is installed on the opposite side of the inflatable member 202 in the housing 201, a connecting member 204 is installed inside the inflating member 203, a valve member 205 is connected inside the connecting member 204, an air core member 206 is arranged inside the air core member 206, and a connecting member 207 is also arranged outside the air core member 206.

[0046] Furthermore, the inflatable member 202 includes an airbag 202a installed inside the outer shell 201, and a one-way valve 202b is arranged on the outside of the airbag 202a. The one-way valve 202b is embedded in the outer shell 201. The one-way valve 202b is set for one-way air intake, that is, air can only enter the airbag 202a through the one-way valve 202b, and cannot escape from the airbag 202a through the one-way valve 202b. An air intake pipe 202c is also installed on the same side surface of the air intake valve, and the other end of the air intake pipe 202c passes through the outer shell 201 and is connected to the inflating member 203.

[0047] The inflating member 203 includes an outer tube 203a connected to the air inlet pipe 202c, and the outer tube 203a and the air inlet pipe 202c are movably connected. The outer tube 203a is also arranged inside the outer shell 201. At the same time, a transmission tooth 203b is coaxially fixed on the outer wall of the end of the outer tube 203a. The outer side of the transmission tooth 203b is meshed with a driven tooth 203c. The driven tooth 203c is rotatably installed on the front cover plate 102 and is opposite to the airbag 202a. The surface of the driven tooth 203c is also provided with two extrusion plates 203d in a ring array, and the extrusion plate 203d can squeeze the airbag 202a.

[0048] The connecting member 204 includes an inner cylinder 204a arranged inside the outer cylinder 203a, and openings 204b are symmetrically left on the inner wall of the inner cylinder 204a, and a tension spring 204c is fixedly set deep inside each opening 204b, and the other ends of the two tension springs 204c are fixedly connected to a clamping block 204d, and the tension spring 204c can support and pull the clamping block 204d to achieve smooth resetting of the clamping block 204d after being displaced by external force, and the surfaces of the two clamping blocks 204d are left with abutment 204e.

[0049] The valve member 205 comprises a valve tube 205a which passes through the insulation layer 104 and is fixed thereto. A hollow closing seat 205b is arranged inside the valve tube 205a, and one end face of the closing seat 205b is arranged in a truncated cone shape. Meanwhile, symmetrical bayonet holes 205c are arranged on the outer wall of the valve tube 205a.

[0050] The air core component 206 includes an annular support 206a fixed to one end of the inner wall of the valve tube 205a, and a center rod 206b passes through the interior of the support 206a. The outer diameter of the center rod 206b is smaller than the inner diameter of the closing seat 205b, and a closing disk that can cooperate with the closing seat 205b is arranged on the outside of the center rod 206b. At the same time, a spring 206d is arranged between the closing disk and the support 206a. The spring 206d can support the closing disk so that when the center rod 206b is not subjected to external force, the truncated cone-shaped convex surface of the closing disk is always in contact with the concave surface of the closing seat 205b, thereby achieving the sealing of the valve tube 205a and preventing the internal gas of the insulation layer 104 from leaking out through the valve tube 205a. In addition, a conversion head 206e is coaxially integrated at the end of the center rod 206b, and a conversion column 206f is fixedly arranged on the outer wall of the conversion head 206e.

[0051] The connecting piece 207 includes a connecting pipe 207a passing through the center of the inner tube, and a retaining ring 207b is fixedly sleeved on the outside of one end of the connecting pipe 207a close to the valve piece 205. At the same time, a plurality of air holes 207c are evenly arranged on the outer wall of the connecting pipe 207a, and a conversion seat 207d is coaxially fixedly arranged at the end of the connecting pipe 207a close to the valve tube 205a, and a straight groove 207e, an oblique groove 207f and an annular groove 207g are sequentially arranged on the inner wall of the conversion seat 207d, and the straight groove 207e, the oblique groove 207f and the annular groove 207g are connected to each other, and the connecting pipe 207a is fixed to the outer tube 203a, and both can move axially relative to the inner tube 204a to realize the position switching of the transmission tooth 203b and the retaining ring 207b.

[0052] Preferably, the extrusion plate 203d is arranged on the driven tooth 203c using an arc-shaped plate with an inclined end surface on one side, and before the connection between the connecting member 204 and the valve member 205 is completed, the driven tooth 203c and the transmission tooth 203b are staggered. At this time, even if the transmission tooth 203b rotates, the driven tooth 203c is still in a stationary state, and the extrusion plate 203d will not squeeze and inflate the airbag 202a. When the connection between the connecting member 204 and the valve member 205 is completed, the driven tooth 203c and the transmission tooth 203b are staggered. 203b is now meshed, so that by rotating the outer cylinder 203a, the driven tooth 203c can be rotated under the drive of the transmission tooth 203b, thereby realizing the relative movement between the extrusion plate 203d and the airbag 202a, so that the airbag 202a is gradually squeezed with the help of the inclined surface of the front end of the extrusion plate 203d, so that the gas enters the airbag 202a from the intake pipe 202c through the connecting pipe 207a and the valve pipe 205a to inflate the airbag 202a, and the airbag 202a protects the instrument and keeps it warm and anti-freezing.

[0053] Furthermore, the stopper 204e is wedge-shaped, and the block 204d on the inner cylinder 204a is supported by the tension spring 204c, so that the inclined surface of the stopper 204e on the block 204d is exactly located on the moving path of the stopper 207b, so that when the stopper 207b moves horizontally with the connecting pipe 207a, the stopper 204d can be moved toward the axial direction of the inner cylinder 204a by the front end of the stopper 207b pushing the stopper 204e, so that the block 204d enters the valve pipe 205. The snap fit between the block 204d and the snap fit 205c is completed in the snap fit 205c on the outer wall of a, thereby realizing the connection between the inner cylinder 204a and the valve tube 205a. While ensuring that the gas smoothly enters the thermal insulation layer 104 from the inner cylinder 204a through the valve tube 205a, the connection between the front cover plate 102 and the protective shell 101 can be locked synchronously. At the same time, the annular setting of the push ring 207b can ensure that when the connecting tube 207a rotates, the push ring 207b can always maintain the push limit on the block 204d.

[0054] The side of the closing disk close to the closing seat 205b is arranged in a convex cone shape, and the side of the closing seat 205b opposite to the closing disk is arranged in a concave shape, so that the closing disk can cooperate with the closing seat 205b. When the two are in contact, the valve tube 205a can be closed to prevent the gas in the insulation layer 104 from escaping outward. At the same time, when the two are separated, the valve tube 205a can be opened, thereby inflating the insulation layer 104 to ensure the normal use of the insulation layer 104.

[0055] While the inner cylinder 204a is gradually connected and matched with the valve tube 205a, the conversion head 206e on the end of the center rod 206b is synchronously matched with the conversion seat 207d at the end of the connecting pipe 207a. At this time, the conversion column 206f on the conversion head 206e moves along the straight groove 207e inside the conversion seat 207d to the connection between the straight groove 207e and the inclined groove 207f. The first inclined groove 207f is spirally inclined on the inner wall of the conversion seat 207d. When it is needed When the insulation layer 104 is inflated, the outer cylinder 203a is rotated counterclockwise, and the connecting tube 207a moves synchronously with it. Then, with the cooperation of the first inclined groove 207f and the conversion head 206e, as the first inclined groove 207f rotates, the groove wall squeezes and pushes the conversion column 206f, so that the center rod 206b moves backward to complete the opening of the valve tube 205a, and then the conversion column 206f moves into the annular groove 207g to cooperate with the continuous rotation of the conversion seat 207d.

[0056] A positioning rib 206g is also provided on the outer wall of the center rod 206b, and a notch is left on the inner edge of the support 206a. The positioning rib 206g cooperates with the notch to limit the rotation of the center rod 206b, thereby preventing the center rod 206b from rotating synchronously with the conversion seat 207d when it rotates, thereby affecting the smooth axial movement of the center rod 206b.

[0057] It should be noted that a shift plate 207h is further provided at the connection between the inclined groove 207f and the annular groove 207g. The shift rod is restricted by the groove wall of the annular groove 207g and can only rotate in one direction. Therefore, when the conversion column 206f rotates counterclockwise in the annular groove 207g, it can push the shift plate 207h to rotate each time it passes through the shift plate 207h, so that it can pass smoothly. When the conversion column 206f rotates clockwise, the conversion column 206f cannot push the shift plate 207h to rotate when passing through it, so that the conversion column 206f can rotate when the shift plate 207h is rotated. Under the guidance of the plate 207h, it enters the inclined groove 207f again and moves to the straight groove 207e section, so as to facilitate the subsequent smooth separation between the inner cylinder 204a and the valve tube 205a. That is, during the inflation process, the conversion column 206f can slide smoothly in the annular groove 207g without being affected by the shift plate 207h. When the front cover 102 needs to be opened, the conversion column 206f can be rotated in the opposite direction and return to the straight groove 207e section through the inclined groove 207f under the guidance of the shift plate 207h, so that the inner cylinder 204a and the valve tube 205a can be smoothly disconnected.

[0058] When in use, after placing the corresponding thermal control instrument in the protective shell 101, the front cover 102 is flipped downward to close the protective shell 101. As the front cover 102 is flipped downward, the inner cylinder 204a gradually approaches the valve tube 205a and cooperates with it. At this time, the outer cylinder 203a and the connecting tube 207a are pushed inward, so that the transmission tooth 203b moves to the same plane as the driven tooth 203c, and the two are meshed. At the same time, the butt ring 207b contacts the butt opening 204e on the surface of the block 204d, and the inclined surface on one side of the butt opening 204e is set, so that the block 204d on the inner cylinder 204a moves to the bayonet 205c on the valve tube 205a. Through the engagement of the block 204d and the bayonet 205c, after the inner cylinder 204a and When the valve tube 205a is connected in place, the front cover 102 and the protective shell 101 are locked, so as to prevent the front cover 102 from shaking and opening easily due to being unrestricted. After the above-mentioned docking is completed, the conversion column 206f on the conversion head 206e synchronously moves to the starting end of the inclined groove 207f through the straight groove 207e of the conversion seat 207d, and then the outer cylinder 203a is rotated counterclockwise, and the outer cylinder 203a and the connecting tube 207a rotate synchronously. The action of the inclined groove 207f on the conversion column 206f pushes the center rod 206b to move backward to open the valve tube 205a. At the same time, accompanied by the transmission of the transmission tooth 203b to the driven tooth 203c, the extrusion plate 203d on the driven tooth 203c intermittently squeezes the airbag 202a, thereby The gas inside the airbag 202a enters the connecting pipe 207a through the air intake pipe 202c, and then enters the inner tube 204a through the air hole 207c on the end of the connecting pipe 207a, and finally enters the insulation layer 104 through the valve tube 205a, so that the insulation layer 104 is filled with air, and with the cooperation of the blocking block 104a, the flow of air inside it is reduced, so that the heat generated by the heating plate 103 can be locked in the insulation layer 104, so as to achieve the purpose of heat preservation and antifreeze of the thermal control instrument. After the insulation layer 104 is filled with air, the outer tube 203a is reversed, and the conversion column 206f rotates inside the annular groove 207g, and under the guidance of the dial plate 207h, it returns to the straight groove 207e from the inclined groove 207f again. At this time, the center rod 206b can be pushed by the spring 206d. The valve tube 205a is reset to realize the secondary closure of the valve tube 205a. When the air in the insulation layer 104 needs to be discharged, the center rod 206b is pushed backward to open the valve tube 205a, so that the air in the insulation layer 104 can be released, so as to take out the thermal control instrument. Through the synchronous cooperation of the connecting piece 204 and the connecting piece 207, with the help of the engagement between the block 204d and the bayonet 205c, while the connection between the front cover plate 102 and the protective shell 101 is locked, the synchronous cooperation between the transmission tooth 203b and the driven tooth 203c can be achieved. Through the cooperation among the inflating piece 202, the pumping piece 203, the connecting piece 207 and the valve piece 205, the inflation operation of the insulation layer 104 can be realized by rotating the pumping piece 203.With the cooperation of the insulation layer 104 and the heating plate 103, the gas inside the insulation layer 104 is nearly static through the blocking block 104a added in the insulation layer 104, and the thermal conductivity of the gas is low, which can greatly improve the insulation capacity of the device and achieve the purpose of protecting the thermal control instrument. The insulation layer 104 filled with air can also fix and buffer the thermal control instrument to ensure the stable placement of the thermal control instrument in the device.
