Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, and in particular to a bubble-leakage-proof refrigerator bottom plate reinforcement structure and a refrigerator. Background Art

[0002] With the continuous development of refrigerator technology, refrigerators are gradually moving towards lightweight and energy-saving. The existing refrigerator market competition is becoming more and more fierce, especially with the increase of material costs and labor costs, which has greatly reduced the profit margin of refrigerators. Among them, using plastic products to replace metal parts in refrigerators to reduce costs has become the main direction of refrigerator production.

[0003] However, the design of the existing refrigerator bottom plate is unreasonable. A circular hole is opened on the bottom plate of the refrigerator for arranging the pipeline. At the same time, in order to improve the insulation effect, the bottom plate of the refrigerator needs to be foamed. Therefore, a sealing ring must be installed on the pipeline when installing the pipeline to avoid leakage at the circular hole. However, this method makes the pipeline installation inconvenient, time-consuming and labor-intensive, and seriously affects the production speed. For this reason, the material of the refrigerator bottom plate is replaced with PVC. Since the refrigerator bottom plate is made of PVC, the thickness is only 0.2-0.4mm, the strength is poor, and the edges are easy to bend, which affects the anti-drop performance of the refrigerator during testing. Summary of the invention

[0004] The purpose of the present invention is to provide a bubble-proof refrigerator bottom plate reinforcement structure, which overcomes the shortcomings of the prior art.

[0005] To solve the above problems, the technical solutions adopted by the present invention are as follows:

[0006] A bubble-proof refrigerator bottom plate reinforcement structure comprises a crossbeam, wherein both ends of the crossbeam are respectively provided with a mounting opening, both sides of the mounting opening and the edges of the bottom are provided with outwardly extending limiting plates, and a reinforcing body is installed on the limiting plates.

[0007] Wherein, the top and bottom edges of the cross beam are further provided with folded portions extending toward one side of the limiting piece, and the folded portions at the mounting opening are clamped with the bottom and top edges of the reinforcement body.

[0008] Wherein, a connecting portion is also provided at the top of the folded portion at the top of the beam outside the installation opening.

[0011] Wherein, a chamfer is arranged on the top of the T-shaped structure.

[0012] Among them, the reinforcement is provided with at least one snap-in groove extending from the top of the reinforcement to the lower part, the snap-in groove cooperates with the mounting port, the bottom of the snap-in groove is an arc-shaped structure, and the inner wall of the snap-in groove at the rear of the reinforcement is provided with a mounting groove extending to the rear surface of the reinforcement, a sealing block is installed in the mounting groove, the sealing block is an elastic material with a snap-in seam, the snap-in seam extends from the top of the sealing block to its lower part, and the snap-in seam cooperates with the snap-in groove.

[0013] Wherein, the sealing block is formed by folding a long strip of elastic material in half, so that a card seam is formed in the middle of the sealing block.

[0014] Wherein, the top of the arc structure and the inner walls on both sides of the clamping groove above the arc structure are also provided with protruding structures that can cooperate with each other.

[0015] Wherein, a through hole cooperating with the arc structure and the protruding structure is also provided at the card seam of the sealing block.

[0016] Wherein, the elastic material is one of rubber, silicone or plastic.

[0017] Wherein, a fixing groove is respectively provided on both sides and below the clamping groove on the front side surface of the reinforcement body, and the fixing groove cooperates with the limiting piece.

[0019] A refrigerator has the above-mentioned reinforcement structure.

[0020] Compared with the prior art, the implementation effects of the present invention are as follows: the reinforcement body of the present invention can be firmly connected to the edge of the refrigerator bottom plate through the clamp head, and the reinforcement body is arranged on the beam between the folded parts, so that the longitudinal compressive strength of the thinner beam is improved, so that the reinforcement structure significantly improves the strength of the edge of the refrigerator bottom plate, saving production costs; in addition, the reinforcement body of the present invention is easy to install, and makes the installation of the pipeline on the refrigerator bottom plate convenient, improving work efficiency, and at the same time, the clamping groove, the installation groove and the sealing block arranged on the reinforcement body cooperate with each other, effectively realizing the sealing of the installation port, avoiding the problem of easy leakage of bubbles when the refrigerator bottom plate is foamed.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-4As shown, the bubble-leakage-proof refrigerator bottom plate reinforcement structure of the present invention includes a cross beam 1, a mounting opening 15 is respectively provided at both ends of the cross beam 1, and a folding portion 11 extending toward one side of a limiting piece 14 is also provided on the top and bottom edges of the cross beam 1, and limiting pieces 14 extending outward are provided on the edges on both sides and the bottom of the mounting opening 15, a reinforcement body 2 is installed on the limiting piece 14, and the folding portion 11 at the mounting opening 15 is clamped with the bottom and top edges of the reinforcement body 2, so that the reinforcement body 2 can be directly clamped and fixed on the cross beam 1.

[0033] A connecting portion 12 is also provided at the top of the folded portion 11 at the top of the cross beam outside the installation opening 15 , so that the reinforcement structure can be connected to the mechanism provided on other edges of the bottom plate 10 of the refrigerator.

[0034] At the same time, in order to facilitate the connection between the crossbeam 1 and the edge of the rear part of the refrigerator bottom plate 10, a plurality of clamping heads 13 are provided on the surface of the crossbeam on one side of the reinforcement body 2. The clamping head is a convex piece formed by stamping on the crossbeam, and one end thereof is fixedly connected to the crossbeam, so that the clamping head 13 can be directly clamped on the edge of the rear part of the refrigerator bottom plate 10; at the same time, a fixing groove 24 is respectively provided on both sides and below the clamping groove 22 on the front side surface of the reinforcement body 2, and the fixing groove 24 cooperates with the limiting plate 14, and a clamping portion 141 for clamping the reinforcement body is provided at the top of the limiting plate, and the clamping portion 141 is a T-shaped structure fixedly connected to the top of the limiting plate, and a chamfer is provided on the top of the T-shaped structure to facilitate the insertion of the limiting plate into the fixing groove 24.

[0035] The left and right sides of the reinforcement body 2 are provided with extension parts 21 extending outwards, so as to facilitate the connection between the reinforcement body 2 and the crossbeam 1. Figure 3-5 As shown, the reinforcement body 2 is provided with three snap-in grooves 22 extending from the top of the reinforcement body 2 to the bottom, and the snap-in grooves 22 cooperate with the installation opening 15 so that the pipe can be directly snap-into the snap-in grooves 22 from the top of the reinforcement body 2; the bottom of the snap-in grooves 22 is an arc-shaped structure 221.

[0036] like Figure 5-7 As shown, the inner wall of the snap-in groove 22 at the rear of the reinforcement 2 is also provided with an installation groove 23 extending to the rear surface of the reinforcement 2, and a sealing block 3 is installed in the installation groove 23.
