This solution cannot meet the two requirements of easy installation and firm installation at the same time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a metal door frame strip for a double-door refrigerator. This solves the problem of using an integrated metal door frame and metal mounting strip, which achieves convenient installation but has poor installation stability. This solution cannot simultaneously meet the dual requirements of convenient and stable installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal door frame strip for a double-door refrigerator, including a door frame strip, wherein a plurality of mounting components are fixedly connected at equal intervals from top to bottom on the side of the door frame strip, and the side of the mounting components is fixedly connected to the external double-door refrigerator cabinet door, and an installation opening is provided on the surface of the door frame strip, and a sensing component is fixedly connected inside the installation opening.

[0007] The installation assembly includes an expansion structure fixedly connected to the side of the door frame strip, and a strong magnetic block is slidably connected inside the expansion structure. A sleeve is slidably connected to the surface of the strong magnetic block, and the sleeve is fixedly connected to the external double-door refrigerator cabinet door.

[0008] In one specific embodiment, the expansion structure includes a groove fixedly connected to the side of the door frame strip, and a sealing film is fixedly connected to the inner wall of the groove, with foaming adhesive disposed inside the sealing film.

[0009] In one specific embodiment, a strong magnetic block is fixedly connected to the side of the sealing film, and the interior of the sealing film is filled with foam and has been dried.

[0010] In one specific embodiment, the side of the chute is provided with air inlets in a circular array for air intake, and the air inlets provide moisture for the chemical reaction of the foam.

[0011] In one specific embodiment, the sensing component includes a device box fixedly connected to the side of the mounting port, and an infrared sensor is sleeved inside the device box. A buzzer electrically connected to the infrared sensor is fixedly connected to the side of the device box.

[0012] In one specific embodiment, a plurality of wire harness plates are fixedly connected at equal intervals from top to bottom on the side of the door frame strip, and the side of the wire harness plates is provided with rubber sheets for protecting the wires.

[0013] Compared with the prior art, this utility model provides a metal door frame strip for a double-door refrigerator, which has the following characteristics:

[0014] Beneficial effects:

[0015] In the technical solution disclosed in this utility model, the door frame strip is placed on the surface of the external double-door refrigerator cabinet door, and the sleeve is fixedly connected to the surface of the double-door refrigerator cabinet door. The expansion structure automatically expands by the drive of the strong magnetic block, squeezing and fixing the strong magnetic block inside the sleeve, thus completing the installation operation of the door frame strip. This not only facilitates installation but also improves the installation firmness.

[0016] When the door frame strip is inserted into the surface of the double-door refrigerator door using the installation components of this invention, the strong magnetic block moves inside the groove due to its own magnetic attraction. The strong magnetic block is magnetically connected to the inside of the sleeve. At the same time, when the strong magnetic block moves due to the magnetic attraction of the sleeve, it will cause the sealing film fixed on the back to deform until it breaks, exposing the expanding foam. External air enters the inside through the air inlet on the surface of the groove and reacts chemically with the expanding foam. The expanding foam expands and solidifies rapidly, squeezing the strong magnetic block and limiting its position. The strong magnetic block is installed inside the sleeve due to its own magnetic attraction and the squeezing of the expanding foam. The sleeve is fixedly connected to the surface of the external double-door refrigerator door, completing the limiting installation operation of the door frame strip. This achieves convenient and quick installation of the door frame strip, and the installation is more secure. Attached Figure Description

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4 In one embodiment of this utility model, a metal door frame strip for a double-door refrigerator includes a door frame strip 1. Several mounting components 2 are fixedly connected at equal intervals from top to bottom on the side of the door frame strip 1. The side of the mounting components 2 is fixedly connected to the external double-door refrigerator cabinet door. An installation opening is provided on the surface of the door frame strip 1, and a sensing component 3 is fixedly connected inside the installation opening.

[0025] The specific problem addressed in this embodiment is that while using an integrated metal door frame and metal mounting strip achieves convenient installation, it suffers from poor installation stability, failing to simultaneously meet the dual requirements of easy and secure installation. This invention utilizes a door frame strip 1 placed on the surface of an external double-door refrigerator cabinet door, with a sleeve 23 fixedly connected to the door surface. An expansion structure 21 automatically expands under the influence of a strong magnet 22, pressing and fixing the magnet 22 inside the sleeve 23, thus completing the installation of the door frame strip 1. This achieves both convenient installation and improved installation stability.

[0026] The mounting assembly 2 includes an expansion structure 21 fixedly connected to the side of the door frame strip 1, and a strong magnetic block 22 is slidably connected inside the expansion structure 21. A sleeve 23 is slidably connected to the surface of the strong magnetic block 22, and the sleeve 23 is fixedly connected to the external double-door refrigerator cabinet door. In this specific embodiment, the expansion structure 21 includes a groove 211 fixedly connected to the side of the door frame strip 1, and a sealing film 212 is fixedly connected to the inner side wall of the groove 211. Foam 213 is provided inside the sealing film 212. When the door frame strip 1 is inserted into the surface of the double-door refrigerator door, the strong magnetic block 22 will move inside the slide groove 211 due to its own magnetic attraction. The strong magnetic block 22 is magnetically connected to the inside of the sleeve 23. At the same time, when the strong magnetic block 22 moves due to the magnetic attraction of the sleeve 23, it will cause the sealing film 212 fixed on the back to deform until it breaks, exposing the expanding foam 213. External air enters into the interior through the air inlet on the surface of the slide groove 211 and reacts chemically with the expanding foam 213. The expanding foam 213 expands and solidifies rapidly, squeezing the strong magnetic block 22 and limiting its position. The strong magnetic block 22 is installed inside the sleeve 23 due to its own magnetic attraction and the squeezing of the expanding foam 213. The sleeve 23 is fixedly connected to the surface of the external double-door refrigerator door, completing the limiting installation operation of the door frame strip 1. This achieves the effect of convenient and quick installation of the door frame strip 1, and the installation is more secure.

[0027] In this specific embodiment, a strong magnetic block 22 is fixedly connected to the side of the sealing film 212, the interior of the sealing film 212 is filled with foam 213 and the interior has been dried; the side of the slide groove 211 is provided with air inlets in a ring array for air intake, and the air inlets provide moisture for the chemical reaction of the foam 213.

[0028] The sealing film 212 can prevent moisture in the outside air from reacting prematurely with the expanding foam 213, which would lead to the failure of the overall structure; during installation, the air inlet can provide the expanding foam 213 with the moisture conditions for chemical reaction.

[0029] The sensing component 3 includes a device box 31 fixedly connected to the side of the mounting port, and an infrared sensor 32 is sleeved inside the device box 31. A buzzer 33 electrically connected to the infrared sensor 32 is fixedly connected to the side of the device box 31.

[0030] There is a certain distance between the side of the door frame strip 1 and the main body of the refrigerator. When the cabinet door is not fully closed, the infrared sensor 32 will detect the abnormal distance and control the buzzer 33 to start working to remind the user that the cabinet door is not closed.

[0031] Several wire harness plates 4 are fixedly connected at equal intervals from top to bottom on the side of the door frame strip 1, and rubber sheets 5 for protecting the wires are provided on the side of the wire harness plates 4.

[0032] The external wiring of the infrared sensor 32 and the buzzer 33 can be organized by the wiring harness 4 to avoid random placement that could affect the installation of the door frame strip 1, while the rubber sheet 5 can prevent the wiring from rubbing against the wiring harness 4 and causing damage.

[0033] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0034] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
