[0002] Cold storage refers to a device that uses artificial means to create an environment with a different temperature or humidity from the outdoor temperature and humidity to store food, liquids, chemicals, medicines, vaccines, scientific experiments and other items at a constant temperature and humidity.

[0003] Existing food cold storage usually has a temperature sensor installed in the cold storage, and the temperature in the cold storage is monitored in real time by the temperature sensor to meet the requirements of food storage. However, due to the low temperature in the cold storage, the temperature sensor is placed in the cold storage in an ultra-low temperature environment for a long time, which is prone to failure. When the power is cut off in the cold storage or the temperature rises due to other reasons, the buzzer cannot sound the alarm in time, which can easily cause property loss and bring inconvenience to use. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a low-temperature food storage device with an alarm function, which can effectively solve the problem that the temperature sensor of the prior art is easily malfunctioning when placed in a cold storage in an ultra-low temperature environment for a long time, and the buzzer cannot sound an alarm in time when the power is cut off in the cold storage or the temperature rises due to other reasons, which easily causes property loss.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] According to the above-mentioned low-temperature food storage device with an alarm function, a rubber pad is fixedly bonded to the upper end of the touch panel.

[0008] According to the above-mentioned low-temperature food storage device with an alarm function, the guide groove is narrow at the front and wide at the back, and the shape of the guide block is adapted to the shape of the guide groove.

[0009] According to the above-mentioned low-temperature food storage device with an alarm function, the limit assembly includes two mounting plates symmetrically fixedly connected in a groove, and sliding grooves are symmetrically fixedly provided at opposite ends of the two mounting plates.

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] Example: Refer to Figures 1 to 3 A low-temperature food storage device with an alarm function comprises an inner wall 1 of a cold storage, the device further comprises a groove 2 opened on the inner wall 1 of the cold storage, a mounting groove 3 connected to the upper side of the groove 2 is opened on the inner wall 1 of the cold storage, a switch 4 is fixedly installed in the mounting groove 3, a fixing plate 5 is fixedly connected below the switch 4 in the groove 2, a through hole is opened on the fixing plate 5, a sliding rod 6 is slidably connected to the through hole, a touch plate is fixedly connected to the upper end of the sliding rod 6, a rubber pad is fixedly bonded to the upper end of the touch plate, the material of the rubber pad is an elastic material, and the rubber pad is in elastic contact with the switch 4 to protect the switch.

[0022] The lower end of the sliding rod 6 is fixedly connected with a sliding plate 7, and the sliding plate 7 is slidably connected to the inner wall 1 of the cold storage. The rear end of the sliding plate 7 is symmetrically fixedly connected with two guide blocks. The front end of the inner wall 1 of the cold storage is provided with two guide grooves 8 slidably connected to the guide blocks. The guide grooves 8 are narrow at the front and wide at the back, and the shape of the guide blocks is adapted to the shape of the guide grooves 8. The guide blocks are arranged to slide in cooperation with the guide grooves 8 to ensure that the sliding plate 7 will not be displaced in the horizontal direction and has high stability in vertical sliding.

[0023] A return spring 9 is fixedly connected between the guide groove 8 and the guide block, and a memory metal 10 is installed in the groove 2 below the sliding plate 7 through a limiting assembly. Specifically, the limiting assembly includes two mounting plates 11 symmetrically fixedly connected in the groove 2, and sliding grooves 12 are symmetrically fixedly provided at opposite ends of the two mounting plates 11. The sliding groove 12 is slidably connected with a sliding block 13, and a limiting spring 15 is fixedly connected between the sliding block 13 and the sliding groove 12. The limiting spring 15 is always in a compressed state but not in an extreme compression state. The memory metal 10 can be limited by the elastic potential energy of the limiting spring 15, and the limiting spring 15 is never in an extreme compression state, thereby avoiding elastic fatigue of the limiting spring 15 and increasing the service life of the limiting spring 15.

[0024] The main material of the memory metal 10 is usually nickel-titanium alloy. When the temperature changes, the crystal structure of the memory metal 10 will transform between austenite and martensite. In the austenite state, the material can maintain its shape at high temperature, and in the martensite state, the material can maintain its shape at low temperature. When heated again to above the transformation temperature, the memory alloy will change into an austenite structure again and return to its original shape. The memory metal 10 used in this application document will be stretched when the temperature rises to a certain height, so that the upper end of the memory metal 10 is in contact with the sliding plate 7, driving the sliding plate 7 to move upward, driving the sliding rod 6 and the touch plate to slide upward, and a buzzer 16 is also provided on the inner wall 1 of the cold storage. The buzzer 16 is electrically connected to the switch 4. When the touch plate contacts the switch 4, the buzzer 16 starts to alarm.

[0025] A limiting plate 14 is fixedly connected between the two sliding blocks 13. A limiting groove is provided at the front end of the limiting plate 14, and a protective pad is fixedly bonded to the inner wall of the limiting groove. On the one hand, it can cause no damage to the memory metal 10 through elastic contact. On the other hand, it can increase the limiting effect on the memory metal 10 by increasing the static friction. When the memory metal is replaced, the limiting plate 14 is pulled forward to remove the memory metal 10 from between the two mounting plates 11, which facilitates the replacement of the memory metal 10, ensures the performance of the memory metal 10, and is easy and reliable to use.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
