Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of refrigerator door body, concretely to a refrigerator durable reinforcing iron. BACKGROUND

[0002] The reinforcing iron on the refrigerator door body is a metal part installed inside the refrigerator door, usually made of iron or iron alloy, and its shape varies according to the design and reinforcement requirements of the door body, generally in the form of a strip or a frame. The hinge part of the door body is usually subjected to a large force, and after repeated opening and closing of the door body, the door body at the hinge part is prone to deformation or internal foaming layer delamination.

[0003] Based on the above problems, the patent with the patent number CN220818206U discloses a refrigerator door body reinforcing iron structure. By setting the fixing piece, the extension arm and the main body are fixed together. By setting the extension piece, the extension arm is inserted into the inside of the refrigerator door body, the rotating force of the hinge is transmitted to the entire refrigerator door body, the stress area of the refrigerator door body is increased, the damage to the refrigerator door body during hinge rotation is reduced, the service life of the refrigerator door body is prolonged, and the reliability of the refrigerator door body is improved.

[0004] However, when implementing the above-mentioned refrigerator door body reinforcing iron structure, it is found that at least the following problems exist. With repeated opening and closing of the door body of the refrigerator, i.e. opening and closing of the door body along the hinge, the main body and the extension piece at the bolted joint in the reinforcing iron structure are prone to gradual bending with the long-term opening and closing of the door body. Specifically, one of the two extension arms at the back of the door opening and closing part gradually displaces backward along the other extension arm toward the back of the door, causing the main body to gradually bend, the bolted joint to loosen, and the extension arm at the back of the door opening and closing part to no longer be parallel to the other extension arm. The position of the two extension arms is front and back, the main body is bent, the main body no longer fits the back of the refrigerator door, or the main body fits the back of the refrigerator door but the refrigerator door is inclined and upright, resulting in reduced firmness of the reinforcing iron structure and insufficient durability of the reinforcing iron structure, and a relatively short service life.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1 to 5 According to an embodiment of the present utility model, a technical solution is provided: a durable reinforcing iron for a freezer, including an L-shaped sheet metal 1 and a hollow steel rod 2. The opposite sides of the two sheet metals 1 are bent to form a right-angle support portion 3. After the support portion 3 is bent, a groove 4 is formed on the sheet metal 1. The hollow steel rod 2 can be embedded in the groove 4 and fit the groove 4. Multiple bolt holes 5 are opened on both sides of the sheet metal 1, and a limiting hole 6 is opened in the middle section of the hollow steel rod 2.

[0028] Please see Figure 1 , Figure 2 and Figure 3, the hollow steel rod 2 is embedded into the clamping groove 4 of the two sheet metals 1, and then the bolts or expansion bolts are sequentially filled into the bolt holes 5 on the sheet metal 1 and the limiting holes 6 in the middle section of the hollow steel rod 2. After installation, the hollow steel rod 2 is embedded into the clamping groove 4 and adheres to the sheet metal 1, so that the hollow steel rod 2 and the sheet metal 1 are tightly adhered. When the refrigerator door is closed, the hollow steel rod 2 on one side is stressed, the bolts or expansion bolts in the limiting holes 6 form a fulcrum, the hollow steel rod 2 acts as a lever, and part of the pushing force transmitted during door closing is transmitted to the other sheet metal 1. Through the principle of lever, the pushing force at one end of the hollow steel rod 2 during door closing is effectively dispersed, and the hollow steel rod 2 is not easy to bend and deform, effectively improving the firmness, durability and service life of the reinforcing iron structure. The problem of the prior art that the main body and the extension piece bolted in the reinforcing iron structure are easily bent and deformed with the long-term opening and closing of the door body, the main body no longer adheres to the back of the refrigerator door body, or the main body adheres to the refrigerator door body but the refrigerator door body is inclined and vertically erected, resulting in reduced firmness of the reinforcing iron structure, insufficient durability of the reinforcing iron structure, and short service life is solved.

[0029] Please refer to Figure 3 In order to facilitate production and transportation, the length of the supporting part 3 is matched with the width of the clamping groove 4, so that during production, no welding is required, only twice cutting of one side of the sheet metal 1 is required to cut out the supporting part 3. During transportation, multiple sheet metals 1 can be stacked on each other. If the supporting part 3 is welded on the sheet metal 1, multiple sheet metals 1 cannot be overlapped with each other, which easily increases the stacking volume, and the supporting part 3 is easy to bend and break during transportation. The supporting part 3 formed by cutting one side of the sheet metal 1 only needs to be bent by a vice during installation, without a right angle. During installation, the supporting part 3 will naturally adhere to the hollow steel rod 2 and form a right angle between the sheet metal 1.

[0030] Please refer to Figures 3-5 In order to increase the fastening force of the middle part of the sheet metal 1 and reduce the spacing between the two bolt holes 5 in the middle part of the sheet metal 1, the bolts in the middle part of the sheet metal 1 can more concentratedly exert the fastening force, preventing the sheet metal 1 from being displaced or loosened in the middle part.

[0031] Please refer to Figure 1 and Figure 2Two abutting blocks 7 are welded on both ends of the hollow steel rod 2. When the hollow steel rod 2 is embedded into the clamping groove 4 of the sheet metal 1, the edges of the abutting blocks 7 are in close contact with the sheet metal 1 and abut against the sheet metal 1. After the pushing force transmitted by the closing door is transmitted to the abutting block 7 at the other end of the hollow steel rod 2, the abutting block 7 abuts against the sheet metal 1. At this time, the sheet metal 1 abuts against the abutting block 7, and the pushing force can be effectively transmitted to the sheet metal 1. Meanwhile, the abutting block 7 can prevent the sheet metal 1 from deforming, so that the width of the clamping groove 4 is increased, and the limiting effect of the sheet metal 1 on the hollow steel rod 2 is reduced.

[0032] Please refer to Figure 2 By providing the fitting groove 8 on the sheet metal 1, which is matched with the abutting block 7, the two abutting blocks 7 on the hollow steel rod 2 can be embedded into the fitting groove 8 during installation to limit the movement of the hollow steel rod 2. Thus, the hollow steel rod 2 and the sheet metal 1 form a fitting structure during installation, which prevents the hollow steel rod 2 and the sheet metal 1 from moving everywhere during the installation of the bolts or expansion bolts, thereby facilitating the installation.

[0033] Please refer to Figure 2 and Figure 5 To enable the refrigerator to be located between the right angle formed by the supporting part 3 and the hollow steel rod 2 for a long time, reduce the movement, and strengthen the relevance between the refrigerator and the reinforcing iron, the connecting holes 9 are provided on the mutually coinciding parts of the supporting part 3 and the hollow steel rod 2. The connecting hole 9 on the supporting part 3 is provided with a counterbore 10. After the bolt is tightened, the head of the bolt can be completely embedded into the counterbore 10.

[0034] Working principle: During installation, the two sheet metals 1 are placed on both sides of the refrigerator door body, and then the hollow steel rod 2 is placed behind the refrigerator door body. At this time, the two abutting blocks 7 on the hollow steel rod 2 are embedded into the fitting groove 8, so that the sheet metal 1 and the hollow steel rod 2 are simply positioned through the simple mortise and tenon structure. Then, the bolts or expansion bolts are sequentially filled into the bolt holes 5 on the sheet metal 1 and the limiting holes 6 in the middle of the hollow steel rod 2, and are tightened and fixed to form an integral body between the hollow steel rod 2 and the sheet metal 1, which is in close contact with the refrigerator. Finally, the bolt is filled into the connecting hole 9 of the mutually coinciding parts of the supporting part 3 and the hollow steel rod 2, and is bolted and fixed to the refrigerator to complete the installation. In this way, when the refrigerator door is opened and closed, the hollow steel rod 2 on one side is stressed, the bolt or expansion bolt in the limiting hole 6 forms a fulcrum, the hollow steel rod 2 acts as a lever, and part of the pushing force transmitted by the closing door is transmitted to the other sheet metal 1. Through the principle of lever, the pushing force at one end of the hollow steel rod 2 is effectively dispersed. Meanwhile, the hollow steel rod 2 is not easy to bend and deform, which effectively improves the firmness, durability and service life of the reinforcing iron structure.
