Description

Technical Field

[0001] The utility model belongs to the technical field related to refrigerator manufacturing, and particularly relates to a reinforcement plate for a refrigerator. Background Art

[0002] During refrigerator production, the outer frame is composed of side panels, a base, and a back panel. After being assembled with the inner container, the main body is completed after foaming and curing between the inner container and the outer frame. The back panel is a key component of the refrigerator, usually located at the back of the refrigerator, protecting the internal mechanical structure and providing insulation. To ensure stable manufacturing, the back panel requires reinforcement to increase its strength. The material and design of the reinforcement panel have a certain impact on the performance and safety of the refrigerator. The reinforcement panel can protect the electronic components and refrigeration system inside the refrigerator from external damage. The reinforcement panel helps maintain the temperature inside the refrigerator and prevents heat loss or ingress, thereby improving the refrigerator's energy efficiency. However, it still has the following disadvantages in actual use:

[0003] During the production process of refrigerators, reinforcement plates need to be placed between the side frames of the refrigerator and assembled with the refrigerator base. During the production of refrigerators, before foaming, the reinforcement plates are only bonded to the refrigerator side frames with adhesive tape. During transportation, the reinforcement plates are pulled, and during foaming, the reinforcement plates are squeezed. If the reinforcement plates are not strong enough, they will be damaged.

[0004] During the production process of the refrigerator, the reinforcement plate is directly placed inside the side panel. However, during the operation, after the reinforcement plate of the refrigerator is bonded together with the inner assembly of the side panel, when the foaming agent contacts the reinforcement plate, it directly contacts and solidifies with the reinforcement plate. However, the connection between the reinforcement plate and the solidified foaming agent is not tight enough, and it is easy for the solidified foaming agent foam to separate from the refrigerator reinforcement plate due to long-term transportation and other operations, affecting the stability of the refrigerator structure. Utility Model Content

[0005] The purpose of the utility model is to provide a reinforcement plate for a refrigerator. By arranging an inner core plate, a closing assembly and an upper connecting plate, the problem that the reinforcement plate is easily damaged due to force changes during production of the refrigerator, and the connection between the foam and the reinforcement plate is not tight enough after solidification in the refrigerator is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a reinforcement plate for a refrigerator, comprising an inner core plate, a closing component and an upper connecting plate, the closing component comprising an outer fixing frame, the inner core plate being fixed in the outer fixing frame, the inner core plate comprising an upper fixing plate, an insulation strip and a corrugated plate, the upper fixing plate being fixed in the outer fixing frame, the bottom of the upper fixing plate being fixed with insulation strips at equal intervals, the bottoms of all the insulation strips being fixed with a corrugated plate in common, the top of the outer fixing frame being fixed with an upper connecting plate, the top of the upper connecting plate being fixed with fixing strips at equal intervals, when working, the compressive strength and the bending strength along the length direction of the closing component are increased by the corrugated plate included in the inner core plate, the inner core plate is fixed therein when the closing component is working, and the fixing tube is fixed thereon by the fixing strip on the upper connecting plate.

[0008] Furthermore, the inner core board also includes two thermal insulation strips and a lower fixed plate. The lower fixed plate is arranged below the corrugated plate, and two thermal insulation strips are fixed equidistantly on the top of the lower fixed plate. All the two thermal insulation strips are fixed to the bottom of the corrugated plate. When the inner core board is working, the bottom is fixed in the outer fixed frame by the two thermal insulation strips cooperating with the lower fixed plate.

[0009] Furthermore, an upper fixing opening is opened in the center of the top of the outer fixing frame, and a lower fixing opening is opened in the center of the bottom of the outer fixing frame. The outer fixing frame fixes the upper closing plate through the upper fixing opening and fixes the lower closing plate through the lower fixing opening.

[0010] Furthermore, the closing assembly also includes an upper closing plate and a lower closing plate. The upper closing plate is fixed in the upper fixing port, and the lower closing plate is fixed in the lower fixing port. When the outer fixing frame is working, the inner core plate is well sealed therein through the cooperation of the upper closing plate and the lower closing plate.

[0011] Furthermore, the lower closing plate is fixed to the bottom of the lower fixed plate, and the upper closing plate is fixed to the top of the upper fixed plate, so that the inner core plate is stably fixed in the closing assembly.

[0012] Furthermore, the bottom of the upper connecting plate is fixedly connected to the top of the upper closing plate, and a fixing tube is fixed to the top of each fixing strip. The upper connecting plate cooperates with the fixing tube and the fixing strip to increase the connection strength between the reinforcing plate and the foam solidified after foaming by the foaming agent.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the reinforcing plate is easily damaged due to the change of force during the production of the refrigerator by arranging an inner core plate and a closing component. The bottom of the lower closing plate in the lower fixing mouth of the closing component faces the rear side of the refrigerator, and the outer fixing frame and the lower closing plate on the closing component are arranged in the side wall of the refrigerator. During the manufacturing process of the refrigerator, during the pulling process of the refrigerator, the corrugated plate is used to increase the bending strength of the closing component in the length direction. After being compressed, the compressive deformation of the closing component is reduced by the rebound of the corrugated plate, and the deformation of the reinforcing plate during the foaming work of the refrigerator in manufacturing is reduced, so that the strength of the reinforcing plate is higher.

[0015] The utility model solves the problem of insufficient tightness in the connection between the solidified foam and the reinforcing plate in the refrigerator by arranging a closing component and an upper connecting plate. The fixing strip and the fixing tube on the top of the upper connecting plate are arranged in the foaming cavity in the side wall of the refrigerator. When the refrigerator foams, the foaming liquid enters between the side wall and the reinforcing plate of the refrigerator. When working, the foaming liquid is arranged on the foaming surface of the foaming liquid when contacting between the fixing strip and the fixing tube, thereby increasing the contact area between the refrigerator and the foaming liquid when working, increasing the connection strength between the reinforcing plate and the foam that solidifies after foaming, and making the connection between the solidified foam and the reinforcing plate in the refrigerator tighter.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0028] See also Figure 1-8 The utility model is a reinforcement plate for a refrigerator, comprising an inner core plate 1, a closing component 2 and an upper connecting plate 3. The closing component 2 comprises an outer fixing frame 201. When the closing component 2 is working, the inner core plate 1 is fixed therein. The inner core plate 1 is fixed in the outer fixing frame 201. The inner core plate 1 comprises an upper fixing plate 101, an insulation strip 102 and a corrugated plate 103. The upper fixing plate 101 is fixed in the outer fixing frame 201. The insulation strips 102 are fixed at equal intervals at the bottom of the upper fixing plate 101. The corrugated plate 103 is fixed to the bottom of all the insulation strips 102. The upper fixing plate 101 is fixed to the outer fixing frame 201. In the embodiment, the heat-insulating strip 102 and the corrugated plate 103 are connected and arranged in the outer fixing frame 201. When working, the corrugated plate 103 is used to increase the bending strength of the closing component 2 in the length direction. After being compressed, the compressive deformation of the closing component 2 is reduced by the rebound of the corrugated plate 103. An upper connecting plate 3 is fixed on the top of the outer fixing frame 201, which contacts the foaming liquid inside the refrigerator and separates the foaming liquid and the closing component 2. Fixed strips 301 are fixed equidistantly on the top of the upper connecting plate 3, and the fixing tube 302 is fixed above the top of the upper connecting plate 3 through the fixing strips 301.

[0029] Specifically, the inner core board 1 also includes a second insulation strip 104 and a lower fixed plate 105. The lower fixed plate 105 is arranged below the corrugated plate 103, and the top of the lower fixed plate 105 is equidistantly fixed with second insulation strips 104. All the second insulation strips 104 are fixed to the bottom of the corrugated plate 103. When the inner core board is working, the second insulation strip 104 cooperates with the lower fixed plate 105 and is connected to the bottom of the corrugated plate 103, so that when working, the first insulation strip 102 and the second insulation strip 104 are fixed to the corrugated plate 103, thereby increasing the thermal insulation performance of the upper and lower positions of the corrugated plate 103.

[0030] Furthermore, an upper fixing opening 2011 is opened in the top center of the outer fixing frame 201 , and a lower fixing opening 2012 is opened in the bottom center of the outer fixing frame 201 . The outer fixing frame 201 fixes the upper closing plate 202 through the upper fixing opening 2011 and fixes the lower closing plate 203 through the lower fixing opening 2012 .

[0031] Furthermore, the closing assembly 2 also includes an upper closing plate 202 and a lower closing plate 203. The upper closing plate 202 is fixed in the upper fixing opening 2011, and the lower closing plate 203 is fixed in the lower fixing opening 2012. The upper closing plate 202 closes the top of the outer fixing frame 201, and the lower closing plate 203 closes the bottom of the outer fixing frame 201.

[0032] Furthermore, the lower closing plate 203 is fixed to the bottom of the lower fixed plate 105, and the upper closing plate 202 is fixed to the top of the upper fixed plate 101. By fixing the lower closing plate 203 to the bottom of the lower fixed plate 105 and the upper closing plate 202 to the bottom of the upper fixed plate 101, the inner core plate 1 is more stably fixed in the closing assembly 2 during operation.

During the manufacturing process of the refrigerator, during the pulling process of the refrigerator, the corrugated plate 103 is used to increase the bending strength of the closing component 2 in the longitudinal direction. After being compressed, the compressive deformation of the closing component 2 is reduced by the rebound of the corrugated plate 103, thereby reducing the deformation of the reinforcing plate during the foaming work of the refrigerator manufacturing. Specific embodiment 2

[0034] See also Figure 1 、 78. On the basis of the first specific embodiment, the bottom of the upper connecting plate 3 is fixedly connected to the top of the upper closing plate 202, and a fixing tube 302 is fixed to the top of each fixing bar 301. When the upper connecting plate 3 is working, the fixing tube 302 is connected through the fixing bar 301. The fixing tube 302 is arranged on the foaming surface of the foaming liquid, thereby increasing the contact area between the refrigerator and the foaming liquid when the refrigerator is working, and increasing the connection strength between the reinforcing plate and the foam solidified after foaming.

[0035] The operating process of this embodiment is as follows: when working, the fixing strip 301 and the fixing tube 302 on the top of the upper connecting plate 3 are arranged in the foaming cavity in the side wall of the refrigerator. When the refrigerator foams, the foaming liquid enters between the side wall of the refrigerator and the reinforcing plate. When working, when the foaming liquid contacts between the fixing strip 301 and the fixing tube 302, it is arranged on the foaming surface of the foaming liquid through the fixing tube 302, thereby increasing the contact area between the refrigerator and the foaming liquid when working, and increasing the connection strength between the reinforcing plate and the foam solidified after foaming.
