Description

Technical Field

[0001] The utility model belongs to the technical field related to refrigerator sealing, and particularly relates to a door frame sealing structure of a glass door for a refrigerator. Background Art

[0002] Freezers, also called freezers, are used to store food at low temperatures. They are divided into commercial and household types, and the door is opened from the top. They have a freezing function, and some freezers also have a refrigeration function. When the freezer is working, it uses the corresponding equipment to cool the inside of the freezer. In order to facilitate the viewing of the items inside, most freezers generally set the movable door of the freezer as a glass door. Therefore, in order to solve the sealing problem between the glass door and the freezer door frame, a corresponding sealing structure will be used to install it in the door frame of the freezer, so that the glass door can ensure the sealing of the freezer after closing. However, it still has the following disadvantages in actual use:

[0003] 1. When the existing sealing structure is used, since most of them are integrated structures, after the sealing structure is installed on the glass door frame of the refrigerator, the glass door of the refrigerator will hit the sealing structure when it is closed, so that the local position of the sealing structure is easily damaged. Since the sealing structure does not have the function of being disassembled, it can only be replaced as a whole, which will increase the replacement cost;

[0004] 2. The existing sealing structure will be damaged in elasticity after long-term use and when it is hit and squeezed by the glass door, so that the sealing structure cannot return to its original shape, which will affect the sealing effect of the structure. Utility Model Content

[0005] The utility model aims to provide a door frame sealing structure for a glass door of a refrigerator, which solves the problems that a single structure of the sealing structure cannot be replaced, resulting in high replacement costs, and the sealing structure cannot be restored to its original shape after its elastic function is damaged, thereby affecting the sealing effect, through the assembly and disassembly coordination between an assembly block, a sealing strip 1 and a sealing strip 2, and the pushing and resetting of a reset plate by a spring.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a door frame sealing structure of a glass door for a refrigerator, comprising two sealing strips 1 which are symmetrically arranged in the left and right directions and a sealing strip 2 which is located above and below the two sealing strips 1, an assembly block in the shape of an angle is arranged between the sealing strip 1 and the two ends of the sealing strip, a through opening is penetrated between the two ends of the sealing strip 1 and the two ends of the sealing strip 2, a plug-in block which is plugged into the inner position of the through opening is fixed on the two ends of the assembly block, two reset plates which are symmetrically arranged in the front and rear positions are located in the middle of the through opening, and a plurality of springs which are linearly evenly distributed are fixed between the two adjacent reset plates.

[0008] Furthermore, notches are provided at the middle positions of the front and rear sides of the outer periphery of the plug-in block, and positioning strips having the same height as the notches are provided inside the notches.

[0009] Furthermore, the ends of the positioning strip beyond the notch are respectively in contact with two ends of the reset plate which are in the same plane as the positioning strip.

[0010] Furthermore, a curved hole is provided inside the assembly block, and both ends of the curved hole penetrate the end portions where the assembly block is connected to the first sealing strip and the second sealing strip.

[0011] Furthermore, a plurality of rubber convex strips evenly distributed in a linear manner are fixed to each end surface on the left and right sides of the peripheral side of the plug-in block, and each rubber convex strip is arranged perpendicular to the positioning strip.

[0012] Furthermore, positioning openings are provided at positions of the inner side walls at both ends of each through hole corresponding to the positions of the rubber convex strips, and the rubber convex strips are respectively arranged inside the positioning openings corresponding to the positions thereof.

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

[0014] 1. When the utility model is in use, the damaged sealing strip 1, sealing strip 2 and the assembly block connected to the ends thereof are glued, and then squeezed and shrunk, so that the plug-in block can be pulled out from the inner position of the through opening, thereby the sealing strip 1 and the sealing strip 2 can be disassembled and replaced, so that the sealing structure can be separately disassembled without replacing the sealing structure as a whole, which greatly reduces the replacement cost and increases the service life of each structure.

[0015] 2. When the utility model is in use, after the glass door compresses the sealing strips 1 and 2, the two reset plates inside each opening will be compressed to compress the spring. Therefore, after the glass door is opened, the spring is no longer squeezed, and the spring pushes the two reset plates to move in opposite directions, thereby expanding the sealing strips 1 and 2. Therefore, the problem that the sealing structure cannot return to its original shape after the elastic function is damaged is solved, and the stability of the sealing structure can be ensured.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-3 As shown, the utility model is a door frame sealing structure of a glass door for a refrigerator, comprising two sealing strips 1 symmetrically arranged on the left and right and a sealing strip 2 located above and below the two sealing strips 1, an assembly block 3 in a curved angle is arranged between the sealing strip 1 and both ends of the sealing strip, a through opening 102 is penetrated between both ends of the sealing strip 1 and the sealing strip 2, a plug-in block 301 plugged into the inner position of the through opening 102 is fixed at both ends of the assembly block 3, two reset plates 4 symmetrically arranged in the front and rear positions are located in the middle of the through opening 102, a plurality of springs 401 uniformly arranged in a linear manner are fixed between the two adjacent reset plates 4, and the reset plate 4 can be reset by using the spring 401, so as to push and reset the sealing strip 1.

[0024] A notch 303 is provided in the middle of the front and rear sides of the outer periphery of the plug-in block 301, and a positioning strip 305 with the same height as the notch 303 is provided inside the notch 303. The ends of the positioning strip 305 exceeding the notch 303 are respectively abutted against the two ends of the reset plate 4 which are in the same plane with the notch. When the plug-in block 301 is inserted into the internal position of the through-port 102, the plug-in block 301 will drive the positioning strip 305 to be inserted into the internal position of the through-port 102, and the positioning strip 305 will abut the reset plate 4, so that the reset plate 4 will not deviate arbitrarily in the internal position of the through-port 102. At the same time, the positioning strip 305 is not the internal position of the mounting rod in the notch 303, so the positioning strip 305 can be replaced so as to replace the positioning strip 305 of different lengths.

[0025] The assembly block 3 is provided with a curved hole 304 inside. Through the opening of the curved hole 304, the assembly hole can also be compressed according to the sealing strip 1 and the sealing strip 2. Both ends of the curved hole 304 penetrate the ends of the assembly block 3 connected with the sealing strip 1 and the sealing strip 2. A plurality of linearly evenly distributed rubber convex strips 302 are fixed to each end face on the left and right sides of the plug-in block 301, and each rubber convex strip 302 is vertically arranged with the positioning strip 305. The inner side walls of the two ends of each through hole 102 correspond to Positioning openings 101 are provided at the positions of the rubber convex strips 302, and the rubber convex strips 302 are respectively arranged inside the positioning openings 101 corresponding to their positions. When the plug-in block 301 is inserted into the internal position of the through opening 102, the plug-in block 301 will drive the rubber convex strips 302 to be inserted into the through opening 102, and as the plug-in block 301 moves, the rubber convex strips 302 will also move with it and move to the internal position of the positioning opening 101, thereby making the position of the plug-in block 301 inside the through opening 102 more stable.

[0026] A specific application of this embodiment is: through the use of the above structure, when the sealing structure is used, the sealing strip 1 and the sealing strip 2 are first assembled by the assembly block 3, and are bonded to the door frame of the refrigerator by glue. Therefore, after the glass door of the refrigerator is closed, the glass door will compress the sealing strip 1, the sealing strip 2 and the assembly block 3, so that the three will be deformed. At this time, the sealing strip 1, the sealing strip 2 and the assembly block 3 seal the door frame. At the same time, since the sealing strip 1 and the sealing strip 2 are both plugged into the inside of the through hole 102 by the plug-in block 301 at the end of the assembly block 3, when the sealing strip 1 and the sealing strip 2 need to be assembled, the sealing strip 1 and the sealing strip 2 are assembled. When replacing damaged ones, firstly glue the damaged sealing strip 1, sealing strip 2 and the assembly block 3 connected to the ends thereof, and then squeeze and shrink them to pull out the plug-in block 301 from the internal position of the through-port 102, thereby the sealing strip 1 and sealing strip 2 can be disassembled and replaced. At the same time, after compressing the sealing strip 1 and sealing strip 2, the glass door will compress the two reset plates 4 inside each through-port 102 to compress the spring 401. Therefore, after opening the glass door, the spring 401 is no longer squeezed, and thus it will move in opposite directions through the two reset plates 4, thereby expanding the sealing strip 1 and sealing strip 2.
