Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator temperature control, in particular to a refrigerator cold storage room temperature sensing sleeve fixing device. BACKGROUND

[0002] At present, most refrigerators are controlled by temperature controllers to control the opening and closing of the refrigerator, thereby accurately controlling the temperature in the refrigerator. Therefore, the fixing method and position of the temperature controller temperature sensing sleeve will directly affect the measurement of the temperature of the refrigerator and further affect the performance of the refrigerator.

[0003] In the prior art, a temperature sensing sleeve pipe positioning device with publication number "CN104275573A" clamps the pipe by cooperating the first clamping part with the second clamping part, and at the same time, the temperature sensing sleeve is sleeved in the third clamping part. At this time, the pipe and the temperature sensing sleeve are relatively immobile and have no gap cooperation. The temperature sensing sleeve positioning device is accurate and firm when welding, and reduces personnel costs.

[0004] However, in the use process, there are still obvious defects: 1. The above device clamps the pipe by cooperating the first clamping part with the second clamping part, and at the same time, the temperature sensing sleeve is sleeved in the third clamping part, so that the pipe and the temperature sensing sleeve are relatively immobile. However, it needs multiple operation steps, which will cause low installation efficiency; 2. The position near the temperature sensing sleeve in the refrigerator is usually filled with foaming agent. If the above device is used, the foaming agent can easily wrap the pipe.

[0042] Working principle:

[0043] In the installation, the fixed buckle body 1 is buckled on the temperature controller temperature sensing tube, the fixed buckle body 1 includes the protruding part 101 in the middle, forming a semi-closed space, and the outer extension part 102 on both sides of the protruding part 101, the outer extension part 102 extends outward, the leading end of the fixed buckle body 1 is an open structure, the tail end edge is a circular arc and is closed, the tail end closed can better block the foaming agent and improve the isolation effect, the inner side of the protruding part 101 is provided with the elastic pad 2, and the elastic pad 2 and the protruding part 101 are filled with high-thermal-conductivity silicone grease 3, the temperature sensing reaction device can conduct heat to the high-thermal-conductivity silicone grease 3, the high-thermal-conductivity silicone grease 3 will be wrapped on the temperature sensing sleeve, therefore, when the temperature of the temperature sensing sleeve rises, the temperature of the high-thermal-conductivity silicone grease 3 will also rise, and the high-thermal-conductivity silicone grease 3 can be kept in a paste or flow state, and the non-solid characteristic thereof can be more attached to the surface of the temperature sensing sleeve, thereby realizing a better temperature conduction effect.

[0044] After installation, the sealing filling device can be triggered passively, that is, the pressing plate 39 is pressed downward, the pressing plate 39 first drives the first longitudinal pointed rod 38 to press downward, so that the first thinning part 361 of the first sealant storage bag 36 is pierced, causing the glue inside the first sealant storage bag 36 to flow out and fill and seal the gap between the outer extension part 102 and the mounting surface, avoiding the subsequent foaming agent from penetrating, at this time, the pressing degree of the pressing plate 39 can be reasonably controlled according to the size of the gap, if the glue in the first sealant storage bag 36 is not enough to fill the gap, due to the height difference between the piercing parts, the pressing plate 39 is further pressed downward, so that the pressing plate 39 drives the second longitudinal pointed rod 42 to press downward in sequence through the first longitudinal pointed rod 38 and the side plate 41, so that the second thinning part 371 of the second sealant storage bag 37 is pierced, at this time, the glue inside the second sealant storage bag 37 also flows out, further supplementing the gap between the outer extension part 102 and the mounting surface.

[0045] Finally, in use, if the temperature of the temperature sensing tube rises, the temperature of the high thermal conductivity silicone grease 3 will also rise and conduct through the thermal conductivity rod 8, causing the thermal expansion and contraction particles 9 to expand, the movable plate 6 is pushed upwards, causing the gas in the hollow strip 4 to be pushed towards the loading housing 18 through the first communication pipe 5 and the second communication pipe 20, and then push the push plate 17, which has a tendency to push the mounting plate 13, so that the elastic air bag 14 has a tendency to be pressed down, and then the elastic air bag 14 is more fitted to the mounting surface, and the elastic air bag 14 has elasticity, its surface is soft and its shape is more fitted, but if the elastic air bag 14 is filled with gas, the elastic air bag 14 will not be pressed down, the stiffness coefficient of the second spring 15 and the fifth spring 31 is smaller than that of the fourth spring 24, so when the gas in the loading housing 18 pushes the push plate 17 downwards, the second spring 15 and the fifth spring 31 are compressed first, causing the mounting plate 13 to have a tendency to press down the elastic air bag 14, if it cannot be pressed down, the increase of the gas will cause the pressure, at this time the sliding plate 23 will be pushed and the fourth spring 24 will be compressed; when the temperature of the temperature sensing tube decreases, the thermal expansion and contraction particles 9 made of memory metal will automatically contract, and then the device returns to the initial state;

[0046] When the second sealant storage bag 37 is not in use, if the elastic air bag 14 is damaged, the temperature sensing reaction device will automatically trigger the sealing and filling device at high temperature, specifically, after the elastic air bag 14 is damaged, the mounting plate 13 can be pressed down, at this time the mounting plate 13 will press down the trigger plate 30, the trigger plate 30 presses down the first piston plate 27 through the extension rod 29, under the action of the piston medium, the second piston plate 28 at the other end drives the transverse sharp cone rod 32 to move outward, and then after passing through the through hole 341 opened on the first partition plate 34, the second sealant storage bag 37 is pierced, causing the glue inside the second sealant storage bag 37 to flow out, timely filling the gap between the damaged elastic air bag 14 and the mounting surface, achieving automatic repair, and better use effect.
