DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0023] The utility model discloses a refrigerating refrigerator, comprising a cabinet body with a refrigerating device, wherein a refrigerator door body is rotatably connected to the opening side of the cabinet body. By improving the handle assembly structure on the refrigerator door body, the handle is easy to assemble, firmly assembled, not easy to fall off, and thus strong and durable.

[0024] Combination Figure 1-Figure 3 In the first embodiment shown, the utility model discloses a durable refrigerator door, comprising a door body 1, a door frame 2 covering the circumference of the door body 1, and a handle 3 fixedly mounted on the door frame 2, wherein the handle 3 is used to allow a user to operate the refrigerator door.

[0025] The door body 1 generally adopts a blister panel or a hollow glass panel with better heat preservation performance. In order to facilitate the user to observe the inside of the cabinet, the door body 1 usually adopts a double-layer or even triple-layer hollow glass panel.

[0026] The door frame 2 is usually made of a plastic door frame or a metal door frame with sufficient rigidity, or a composite door frame formed by surrounding the outer side of a plastic door frame with a metal door frame.

[0027] The handle 3 includes a long pull rod 31 and at least two pull rod bases 32 which are integrally structured with the pull rod 31 , and the pull rod bases 32 are assembled and fixed to the door frame 2 by using the pull rod bases 32 .

[0028] In order to overcome the problem that the prior art needs to use screws to fix the handle 3 from the inside of the door sill 2 to the outside, which is inconvenient to assemble due to limited operating space, and the handle 3 is prone to loosening of the screws during long-term use, thereby causing the handle 3 to fall off from the door frame 2, the present embodiment makes the following improvements to the assembly structure of the handle 3:

[0029] An assembly hole is provided on the door frame 2, in which a rivet nut 4 is riveted; a pin 5 is matched with the rivet nut 4, the lower end of the pin 5 is riveted to the rivet nut 4, the upper end of the pin 5 is exposed outside the door frame 2, and the upper end of the pin 5 has a limiting ring groove 51; the pull rod base 32 has a longitudinal axis hole 321 and a transverse lock hole 322.

[0030] When assembling the handle 3 and the door frame 2, the upper end of the pin 5 is inserted into the longitudinal axis hole 321 of the pull rod base 32, and a locking screw (not shown) is passed through the transverse locking hole 322 and extended into the limiting ring groove 51 of the pin 5, so that the pin 5 and the pull rod base 32 are locked.

[0031] By utilizing the characteristics of the rivet nut 4, when the lower end of the pin 5 is pressed into the rivet nut 4 to achieve riveting, the rivet nut 4 itself is deformed, so that the pin 5 is riveted into the assembly hole of the door frame 2 and locked firmly, so that the pin 5 will not loosen from the assembly hole of the door frame 2 during long-term use of the handle 3.

[0032] It can be seen that since the upper end of the pin 5 is exposed outside the door frame 2, when the handle 3 is fastened and assembled with the door frame 2 using the pin 5, there is a large operating space and it is convenient to assemble; at the same time, the lower end of the pin 5 is riveted to the door frame 2 using the rivet nut 4, and the upper end of the pin 5 is inserted into the longitudinal axis hole 321 of the pull rod base 32, and the locking screw is used to cross the transverse lock hole 322 of the pull rod base 32 and the limiting ring groove 51 of the pin 5 to achieve assembly, so that the assembly structure is firm, and the handle 3 and the door frame 2 are not easy to loosen, which is beneficial to improve the durability of the refrigerator door and improve the user experience.

[0033] In addition, the door body 1 is usually provided with a door seal 24, which can improve the sealing performance between the inner side of the door frame 2 of the refrigerator door and the cabinet body, thereby improving the refrigeration effect of the refrigerator.

[0034] Further integration Figure 4-Figure 6 The second embodiment is further optimized based on the first embodiment, or is a parallel implementation with the first embodiment.

[0035] In the second embodiment, a fixing seat 7 with an embedded nut 71 is pre-installed in the door frame 2. The embedded nut 71 is located directly below the assembly hole of the door frame 2. After the lower end of the pin 5 passes through the assembly hole, it is screwed into the embedded nut 71 of the fixing seat 7.

[0036] The threaded area between the embedded nut 71 and the lower end of the pin 5 is much larger than the threaded area between the lower end of the pin 5 and the assembly hole, so that the pin 5 is not easy to get loose from the fixing seat 7, and the pin 5 is not easy to get out of the assembly hole of the door frame 2 during long-term use. In addition, since the fixing seat 7 is located in the door frame 2 and the size of the fixing seat 7 is much larger than the size of the assembly hole, the fixing seat 7 is used to fix the pin 5 to the door frame 2 more firmly.

[0037] The assembly structure between the upper end of the pin 5 and the pull rod base 32 is the same as that of the first embodiment and will not be repeated.

[0038] For example, in order to prevent the pin 5 from passing through the assembly hole and exerting a relatively large force on a part of the door body 1 when the handle 3 is pulled, a buffer pad 6 is provided between the pin 5 and the door frame 2 and / or the door body 1 .

[0039] The fixing seat 7 is usually in the shape of a cube or a polygon. When the pin 5 is screwed into the embedded nut 71, the fixing seat 7 is not easy to rotate, ensuring that the lower end of the pin 5 and the fixing seat 7 are firmly assembled.

[0040] In addition, a mounting groove 21 is provided on the inner side of the door frame 2 . The size of the mounting groove 21 is larger than the fixing seat 7 , so that the fixing seat 7 can be pre-installed into the door frame 2 through the mounting groove 21 .

[0041] Furthermore, an inner cover 23 is provided on the inner side of the door frame 2 to seal the mounting groove 21. In addition, the inner cover 23 is hidden between the door seal 24 and the inner side of the door frame 2.

[0042] A first fixing hole 22 is provided on the inner side surface of the door frame 2, and a second fixing hole 231 is correspondingly provided on the frame inner cover 23. Screws are passed through the first fixing hole 22, the second fixing hole 231 and screwed into the lower end of the embedded nut 71 to achieve the assembly of the frame inner cover 23 on the inner side surface of the door frame 2, and the fixing seat 7 is limited and fixed in the door frame 2.

[0043] Since the size of the fixing seat 7 is much larger than the assembly hole, when the refrigerator door is operated by the handle 3, the force is transmitted to the fixing seat 7 through the pin 5. There is a large effective area between the fixing seat 7 and the door frame 2 to disperse the force, thereby preventing the door frame 2 from being subjected to excessive force locally and deforming, causing the handle 3 to fall off. Therefore, the use of the fixing seat 7 is conducive to improving the durability of the handle 3 to prevent it from falling off.

[0044] When assembling the handle 3, first insert the fixing seat 7 from the installation groove 21 of the door frame 2, and then use screws to lock the frame cover 23, the door frame 2 and the inner side of the door frame 2; then, after the buffer pad 6 is set on the lower end of the pin 5, it passes through the assembly hole of the door frame 2 and is screwed into the embedded nut 71 of the fixing seat 7 from top to bottom to tighten; finally, insert the upper end of the pin 5 into the longitudinal axis hole 321 of the handle 3, and use a locking screw) to pass through the transverse lock hole 322 and extend into the limiting ring groove 51 of the pin 5, so that the pin 5 and the pull rod base 32 can be firmly assembled, which has the characteristics of large assembly operation space, convenient assembly operation, and a firm assembly structure, so that the handle 3 is not easy to loosen.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
