[0018] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] Example

[0020] like Figures 1 to 4 As shown, a high-efficiency heat-insulating cover comprises: a cover body 1, a reinforcing strip 2 is fixedly connected to the outside of the cover body 1, a receiving groove is opened on the top of the cover body 1, a main cylinder 3 is plug-inly connected to the inside of the receiving groove, an extension cylinder 4 is fixedly connected to the top of the main cylinder 3, the insides of the main cylinder 3 and the extension cylinder 4 are interconnected, a control screen 5 is provided on the top of the extension cylinder 4, a frame 6 is fixedly connected to the inside of the main cylinder 3, a track 7 is fixedly connected to the inside of the frame 6, four groups of tracks 7 are provided, and the insides of the four groups of tracks 7 are interconnected, the cover body 1 is placed on the outside of the food to be kept warm, and the cover body 1 is used to wrap the food so that the food is inside the closed space, the heat emitted by the food is blocked, and the heat volatilization time is delayed, and the main cylinder 3 is inserted into the inside of the receiving groove to seal the receiving groove, so that the cover body 1 becomes a whole.

[0021] In this embodiment, a through groove 8 is provided on the outside of the main cylinder 3, and a placement groove is provided at a position corresponding to the through groove 8 on the inner wall of the accommodating groove. A slide bar 9 is slidably connected to the inside of the track 7, and the slide bar 9 extends to the inside of the placement groove. A sealing ring is sleeved on the outer wall of the main cylinder 3. When the main cylinder 3 is inserted into the inside of the accommodating groove, the sealing ring and the accommodating groove rub against each other, so that the stability of the connection between the main cylinder 3 and the accommodating groove is greatly improved. By moving the slide bar 9, the track 7 limits the slide bar 9, so that the slide bar 9 moves along a predetermined route. Finally, the slide bar 9 extends to the inside of the placement groove through the through groove 8, so that the main cylinder 3 is fixed inside the accommodating groove.

[0022] In this embodiment, a rotating shaft 10 is rotatably connected to the middle of the track 7, a knob is fixedly connected to the top of the rotating shaft 10, a turntable 11 is fixedly connected to the outside of the rotating shaft 10, an arc groove 12 is opened inside the turntable 11, and the arc grooves 12 are evenly spaced. A slide post 13 is fixedly connected to the top of the side close to the slide bar 9, and the slide post 13 extends to the outside of the arc groove 12, and a limit ring is fixedly connected to the top of the slide post 13. By rotating the rotating shaft 10, the rotating shaft 10 will transmit the rotational force to the outside of the turntable 11, and then the turntable 11 will follow its rotation, and then the arc groove 12 will follow the rotation and squeeze the slide post 13, and finally the slide post 13 drives the slide bar 9 to move.

[0023] In this embodiment, a guiding cover 14 is fixedly connected to the bottom of the main cylinder 3. The guiding cover 14 is designed in a horn shape. At the top inside the guiding cover 14, a disinfection lamp and a heating lamp are respectively fixedly connected. The operator controls the control panel 5 to turn on the disinfection lamp and the heating lamp, and diffuses the light source through the guiding cover 14 to disinfect and keep warm the food materials, thereby improving the freshness of the food materials.

[0024] In this embodiment, mounting seats are symmetrically and fixedly connected to the top of the cover body 1. A handle 15 is rotatably connected between the mounting seats. An anti-slip sleeve is sleeved on the middle part of the outside of the handle 15. Vent holes 16 are formed in the top of the cover body 1. The operator holds the handle 15 and contacts the anti-slip sleeve. Friction is generated between the anti-slip sleeve and the palm to prevent the phenomenon of slipping off when the handle 15 is lifted to control the cover body 1. At the same time, with the rotatable design of the handle 15, when the handle 15 is rotated to be parallel to the cover body 1, the handle 15 can be hung on the hook, without occupying space. After the heat generated by the heating lamp is mixed with the heat of the food materials themselves, steam will be generated and discharged to the outside through the vent holes 16, preventing the steam from liquefying into water droplets and falling onto the surface of the food materials, which will affect the taste.

[0025] In this embodiment, an extension edge 17 is fixedly connected to the bottom of the cover body 1. Rubber particles are provided at the bottom of the extension edge 17. A sandwich layer is provided inside the cover body 1, and heat insulation cotton is filled in the sandwich layer. When the cover body 1 contacts the tabletop, the extension edge 17 is in a fitting state with the tabletop, preventing heat from flowing out of the cover body 1. Through the design of the sandwich layer and the heat insulation cotton, when the heating lamp is in the heating operation, the outside of the cover body 1 will not be in a high-temperature state, avoiding scalding the operator.

[0026] Embodiment: The cover 1 is placed outside the food to be insulated, and the food is wrapped by the cover 1 so that the food is inside a closed space, blocking the heat emitted by the food and delaying the time of heat volatilization. When the cover 1 contacts the tabletop, it is in a fitting state with the tabletop through the extended edge 17 to prevent heat from flowing out of the cover 1. By inserting the main cylinder 3 into the receiving groove and blocking the receiving groove, the cover 1 is made into a whole. By rotating the rotating shaft 10, the rotating shaft 10 will conduct the rotational force to the outside of the turntable 11, and then the turntable 11 will rotate accordingly. Then, while the arc groove 12 rotates, it squeezes the sliding column 13, and finally the sliding column 13 drives the sliding strip 9 to move, so that the track 7 limits the sliding strip 9, making the sliding strip 9 move along a predetermined route. Finally, the sliding strip 9 extends into the placement groove through the through groove 8, fixing the main cylinder 3 inside the receiving groove. The operator controls the control panel 5 to turn on the disinfection lamp and the heating lamp, and the light source is diffused through the guiding cover 14 to disinfect and keep warm the food, improving the freshness of the food. Through the design of the sandwich layer and the heat insulation cotton, when the heating lamp is working, the outside of the cover 1 will not be in a high-temperature state, avoiding scalding the operator.

[0027] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
