Technical Field
[0001] This utility model relates to the technical field of door frame connection structure for double-door refrigerators, specifically the door frame connection structure for double-door refrigerators. Background Technology
[0002] A refrigerator door frame structure disclosed in CN207035656U includes a trim strip, an upper cover, and an L-shaped door frame. The L-shaped door frame is joined with the trim strip and the upper cover to form the refrigerator door frame. The upper end of the L-shaped door frame is connected to the corresponding upper cover portion, and the lower end of the L-shaped door frame is connected to the corresponding trim strip portion by a snap-fit structure. The snap-fit structure includes an inwardly opening E-shaped baffle, and the inner side of the E-shaped baffle is provided with one or more square plugs arranged in parallel. The upper cover and the trim strip are provided with inwardly recessed E-shaped grooves corresponding to the E-shaped baffles. The inner side of the E-shaped grooves is provided with one or more hollow door-shaped plugs arranged in parallel. The E-shaped baffle is snapped into the corresponding E-shaped groove, and the square plugs are inserted into the hollow portions of the corresponding door-shaped plugs.
[0003] It solves the problem of exposed seams between the cover and trim strip, and improves assembly efficiency.
[0004] The technical solution in the prior art document is convenient for assembly, but the defects are also more obvious. For example, after the simple snap-fit structure is used to assemble the door frame, the snap-fit is not strong enough. Installation holes are still set on the surface of the door frame for reinforcement. Using bolts for further reinforcement will greatly increase the assembly efficiency. This solution cannot simultaneously achieve both high efficiency and strong assembly. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a door frame connection structure for a double-door refrigerator. This solves the problem that simple snap-fit structures, when splicing door frames, have poor snap-fit strength. Installation holes are still set on the surface of the door frame for reinforcement, and using bolts for further reinforcement would greatly increase assembly efficiency. This solution cannot simultaneously achieve both high efficiency and robust assembly.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-door refrigerator door frame connection structure, including a horizontal bar, a groove is provided on the side of the horizontal bar, and a fixing groove is provided on the side of the groove. An installation component is fixedly connected inside the fixing groove, and a locking rod is snapped into the inside of the installation component. The locking rod is fixedly connected to the inner side wall of the vertical bar.
[0007] The mounting assembly includes a mounting block fixedly connected inside the fixing groove, and a sliding groove is provided on the side of the mounting block. A bracket is slidably connected inside the sliding groove, and a plug rod is fixedly connected to the side of the bracket in an axially symmetrical manner.
[0008] In one specific embodiment, a sleeve is fixedly connected to the side of the slide in an axisymmetric manner, and a spring is sleeved inside the sleeve, with a push rod fixedly connected to the side of the spring.
[0009] In one specific embodiment, the mounting block has a mounting groove on its side, and the mounting groove has a sliding hole on its side in an axisymmetric manner, with a plug rod slidably connected inside the sliding hole.
[0010] In one specific embodiment, the side of the locking rod is provided with an insertion hole in an axisymmetric manner, and the inner diameter of the insertion hole matches the sliding hole, and a locking rod is inserted into the inside of the insertion hole.
[0011] In one specific embodiment, one end of the bracket is configured as an extension rod shape, and one end of the bracket protrudes from the side of the sliding groove opened in the mounting block.
[0012] In one specific embodiment, a rubber pad is fixedly connected to the side of the vertical rod, and the size and specifications of the rubber pad are matched with one end of the horizontal rod.
[0013] Compared with the prior art, the present invention provides a door frame connection structure for a double-door refrigerator, which has the following advantages:
[0014] In the technical solution disclosed in this utility model, the two sides of the vertical bar are slightly pried open, so that the locking rods fixed on its side can be moved. Then, one end of the horizontal bar is inserted into the interior of the vertical bar. The vertical bar is loosened and the installation component is operated so that the locking rods fixed on its side are reset and inserted into the installation component on the side of the horizontal bar, thus completing the door frame connection operation of the horizontal bar and the vertical bar, achieving a quick and firm installation effect.
[0015] By slightly prying open both sides of the vertical rod using the mounting components and locking rods provided in this invention, the horizontal rod and the mounting components fixed to its sides are placed inside the vertical rod. Pushing the bracket compresses the spring, causing the insertion holes fixed to the bracket surface to retract into the sliding holes. Releasing the pried-open vertical rod resets both sides, causing the locking rods fixed to the sides to insert into the mounting grooves on the side of the mounting block. Releasing the bracket causes the spring to return, resetting the top rod. Pushing the bracket causes the insertion rods fixed to the bracket surface to protrude from the sliding holes and insert into the insertion holes on the side of the locking rods, completing the installation of the locking rods. This allows the vertical rod, fixed at one end of the locking rods, to be installed on the surface of the horizontal rod fixed to the side of the mounting block, completing the connection and installation of the vertical and horizontal rods to the refrigerator door frame. The mounting block provides initial positioning of the locking rods, and the insertion rods provide secondary positioning of the locking rods, thus achieving a secure and quick installation of the horizontal and vertical rods.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0023] Figures 1-4 In one embodiment of this utility model, the door frame connection structure of a double-door refrigerator includes a horizontal bar 1. A groove is provided on the side of the horizontal bar 1, and a fixing groove is provided on the side of the groove. An installation component 2 is fixedly connected inside the fixing groove, and a locking rod 3 is snapped into the installation component 2. The locking rod 3 is fixedly connected to the inner side wall of the vertical bar 4.
[0024] The specific problem addressed in this embodiment is that the simple snap-fit structure used to assemble the door frame has poor snap-fit strength, still requiring mounting holes on the door frame surface for reinforcement. However, using bolts for further reinforcement significantly increases assembly efficiency. This solution cannot simultaneously achieve both high efficiency and secure assembly. This invention utilizes a slight prying open of both sides of the vertical rod 4, causing the side-fixed locking rods 3 to move and allowing one end of the horizontal rod 1 to be inserted into the vertical rod 4. By releasing the vertical rod 4 and operating the mounting component 2, the side-fixed locking rods 3 are reset and inserted into the mounting component 2 on the side of the horizontal rod 1, completing the connection between the horizontal rod 1 and the vertical rod 4 to the door frame, achieving a quick and secure installation.
[0025] The mounting assembly 2 includes a mounting block 21 fixedly connected inside the fixing groove. The mounting block 21 has a sliding groove on its side. A bracket 22 is slidably connected inside the sliding groove. A rod 23 is fixedly connected to the side of the bracket 22 in an axisymmetric manner. In this specific embodiment, a sleeve 5 is fixedly connected to the side of the sliding groove in an axisymmetric manner. A spring 6 is sleeved inside the sleeve 5. A top rod 7 is fixedly connected to the side of the spring 6. The mounting block 21 has a mounting groove on its side. A sliding hole is slidably opened on the side of the mounting groove. A rod 23 is slidably connected inside the sliding hole. A insertion hole is slidably opened on the side of the locking rod 3 in an axisymmetric manner. The inner diameter of the insertion hole matches the sliding hole. A rod 23 is inserted into the insertion hole. Slightly pry open both sides of the vertical rod 4, place the horizontal rod 1 and the mounting assembly 2 fixed to its side into the interior of the vertical rod 4, push the bracket 22 to compress the spring 6, and the insertion rod 23 fixed to the surface of the bracket 22 retracts into the sliding hole. Release the pried vertical rod 4, and both sides of the vertical rod 4 return to their original positions, causing the locking rod 3 fixed to the side to be inserted into the mounting groove on the side of the mounting block 21. Release the bracket 22, and the spring 6 rebounds, causing the top rod 7 to return to its original position. Push the bracket 22, causing the insertion rod 23 fixed to the surface of the bracket 22 to protrude from the sliding hole and be inserted into the insertion hole on the side of the locking rod 3, completing the installation operation of the locking rod 3. This allows the vertical rod 4 fixed at one end of the locking rod 3 to be installed on the surface of the horizontal rod 1 fixed to the side of the mounting block 21, completing the connection and installation operation of the vertical rod 4 and the horizontal rod 1 to the refrigerator door frame. The mounting block 21 provides initial positioning for the locking rod 3, and the insertion rod 23 provides secondary positioning for the locking rod 3, thereby achieving a firm and quick installation operation for the horizontal rod 1 and the vertical rod 4.
[0026] In this specific embodiment, one end of the bracket 22 is configured as an extension rod shape, and one end of the bracket 22 protrudes from the side of the sliding groove opened in the mounting block 21;
[0027] One end of the protruding bracket 22 is exposed inside the groove. During installation, the extended bracket 22 can be pushed to move its insertion rod 23 to facilitate the installation operation.
[0028] A rubber pad 8 is fixedly connected to the side of the vertical bar 4, and the size and specifications of the rubber pad 8 are matched with one end of the horizontal bar 1;
[0029] When the horizontal bar 1 is installed inside the vertical bar 4, the horizontal bar 1 will squeeze the rubber pad 8. First, the rubber pad 8 will fill the gap at the connection, making the installation tighter. At the same time, the rebound force of the rubber pad 8 will push the horizontal bar 1 to move outward, so that the mounting block 21 on the side of the horizontal bar 1 will squeeze the clamping rod 3, further increasing the firmness of the splicing of the mounting component 2.
[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
