Description

Technical Field

[0001] This utility model relates to the field of refrigerator handle technology, and in particular to an aluminum alloy handle for a refrigerator compartment door that is easy to conceal. Background Technology

[0002] The refrigerator door handle is the core component for opening the refrigerator compartment. It usually adopts an embedded or protruding design. The embedded handle saves space and avoids bumps. The surface is flush with the door panel for easy cleaning. The protruding handle provides a larger force point and is suitable for heavy-door models.

[0003] Chinese patent discloses a refrigerator compartment door (authorization announcement number CN213396110U). This patented technology includes a refrigerator door with a handle mechanism fixedly connected to it. The handle mechanism includes a door handle and a pry bar, which are rotatably connected. The door handle is also connected to the pry bar via a torsion spring. The surface of the pry bar has a bottle cap pry opening. The door handle has an inverted L-shaped structure. The refrigerator door is equipped with an infrared sensing module, a control module, and a display screen. This invention allows for convenient door opening when the user is holding items with both hands. Bottle caps can be opened via the built-in bottle cap pry opening on the handle. The display screen only illuminates when the user is in front of the refrigerator, making it more energy-efficient and practical.

[0004] However, this patent still has shortcomings. When in use, the handle is exposed to the outside, making it susceptible to damage from impacts by external objects. Furthermore, the exposed handle is prone to dust accumulation, bacterial growth, and aesthetic issues. Therefore, those skilled in the art have provided a concealable aluminum alloy handle for refrigerator compartment doors to address the problems mentioned in the background section. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an easily concealable aluminum alloy handle for a refrigerator compartment door, comprising a refrigerator compartment door body, an aluminum alloy handle, a travel plate, a mounting cylinder, a pivot, a spring, and a traveling rod. A metal frame is embedded inside the front end of the refrigerator compartment door body. A rectangular aluminum alloy handle is slidably mounted inside the metal frame. A travel plate is located at the rear end of the aluminum alloy handle. A bottom groove is formed at the lower end of the travel plate, and an assembly groove is formed inside the upper end of the travel plate. A spring is installed between the inner wall of the bottom groove and the inner wall of the rear end of the metal frame. A pivot is rotatably mounted on the upper inner wall of the metal frame. A connecting block is sleeved on the outer wall of the pivot. A torsion spring is sleeved on the outer side of the pivot, with its two ends connected to the metal frame and the connecting block, respectively. A connecting rod is located at the lower end of the pivot. A fixing cylinder is located at one end of the connecting rod. A hollow traveling rod is slidably mounted inside the lower end of the fixing cylinder. A compression spring is installed between the traveling rod and the fixing cylinder.

[0008] Furthermore, the assembly groove is irregularly triangular in shape, and the assembly groove includes a starting groove and a return groove that are herringbone-shaped and interconnected;

[0009] Specifically, the lower end of the walking rod travels inside the starting slot, then inside the assembly slot, and finally through the inlet and outlet slots before returning to the starting slot via the return slot.

[0010] Furthermore, the assembly groove includes an outlet groove connected to one end of the starting groove and an inlet groove connected to one end of the starting groove. A positioning groove is provided between the outlet groove and the inlet groove, and a cliff-shaped cross section is provided at the connection between the inlet groove and the positioning groove.

[0011] Specifically, the traveling rod that moves inside the starting slot is guided into the positioning slot through the guide slot. The cliff-like cross section at the connection between the positioning slot and the guide slot prevents the traveling rod from moving in the opposite direction.

[0012] Furthermore, a connecting bead is provided at the lower end of the walking rod, the compression stroke of the compression spring is less than the height of the connecting bead inside the assembly groove, and a cliff-shaped cross section is provided at the connection between the return groove and the starting groove;

[0013] Specifically, the friction and resistance of the traveling rod moving inside the assembly slot are reduced by connecting beads, and the cliff-shaped cross section at the connection between the return slot and the starting slot prevents the traveling rod from directly entering the return slot through the starting slot, allowing the traveling rod to enter the starting slot only through the return slot.

[0014] Furthermore, the spring is provided with a slidingly inserted plug rod and a mounting cylinder. One end of the plug rod is connected to the inner wall of the rear side of the metal frame, and one end of the mounting cylinder is connected to the inner wall of the bottom groove.

[0015] Specifically, the travel rod located inside the return channel loses its positioning in the positioning slot, the travel rod releases the pulling force on the travel plate, and the elastic force of the spring effectively pushes the travel plate forward. During the extension and contraction of the spring, the spring is prevented from deviating and is guided.

[0016] Furthermore, a sealing ring is embedded in the opening of the mounting cylinder, the plug rod is slidably installed inside the sealing ring, one end of the plug rod is provided with a piston that is slidably installed inside the mounting cylinder, and the inner wall of the mounting cylinder is provided with symmetrically distributed oil grooves.

[0017] Specifically, the piston rod slides inside the sealing ring, causing the piston to slide inside the mounting cylinder. When moving, the piston squeezes the damping oil inside the mounting cylinder and flows through the oil groove. When flowing, it applies resistance to the piston, so that the spring is damped when it returns to its original position, thus achieving smooth spring return and avoiding excessive wear on the stroke plate and aluminum alloy handle caused by the instantaneous release of the spring's elasticity.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention allows for the opening and closing of a refrigerator door by pulling on an aluminum alloy handle. Pressing the handle applies pressure to a spring, and during the reciprocating movement of the travel plate, a traveling rod supported by a torsion spring and pivoting on a rotating shaft, along with a guiding and intermittently positioning assembly slot, allows the handle to be stored within the refrigerator door or moved to the outside. When stored, the refrigerator door surface is flat, preventing the handle from being easily bumped or knocked, ensuring safety during use, preventing dust accumulation, and reducing bacterial growth. When moved to the outside, it is easily gripped. The pressing method for using and storing the aluminum alloy handle is convenient and aesthetically pleasing.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please see Figure 1-6 As shown, this embodiment is an easily concealed aluminum alloy handle for a refrigerator compartment door, including a refrigerator door body 1, an aluminum alloy handle 3, a travel plate 6, a mounting cylinder 15, a pivot 11, a spring 13, and a travel rod 4. A metal frame 2 is embedded inside the front end of the refrigerator door body 1, and a rectangular aluminum alloy handle 3 is slidably installed inside the metal frame 2. A travel plate 6 is provided at the rear end of the aluminum alloy handle 3. A bottom groove 7 is formed at the lower end of the travel plate 6, and an assembly groove 8 is formed inside the upper end of the travel plate 6. The inner wall of the bottom groove 7... A spring 13 is provided between the metal frame 2 and the inner wall of the rear end. A rotating shaft 11 is rotatably installed on the inner wall of the upper end of the metal frame 2. A connecting block 12 is sleeved on the outer wall of the rotating shaft 11. A torsion spring 10 is sleeved on the outer side of the rotating shaft 11, with its two ends connected to the metal frame 2 and the connecting block 12 respectively. A connecting rod 14 is provided at the lower end of the rotating shaft 11. A fixed cylinder 9 is provided at one end of the connecting rod 14. A walking rod 4 with a hollow upper end is slidably installed inside the lower end of the fixed cylinder 9. A compression spring 25 is provided between the walking rod 4 and the fixed cylinder 9.

[0037] The assembly groove 8 is irregularly triangular in shape and includes a starting groove 20 and a return groove 21 that are herringbone-shaped and interconnected.

[0038] The assembly slot 8 includes an outlet slot 23 connected to one end of the starting slot 20 and an inlet slot 22 connected to one end of the starting slot 20. A positioning slot 24 is provided between the outlet slot 23 and the inlet slot 22. A cliff-shaped cross section is provided at the connection between the inlet slot 22 and the positioning slot 24.

[0039] A connecting bead 5 is provided at the lower end of the walking rod 4. The compression stroke of the compression spring 25 is less than the height of the connecting bead 5 inside the assembly groove 8. A cliff-shaped section is provided at the connection between the return groove 21 and the starting groove 20.

[0040] The spring 13 is provided with a sliding plug rod 18 and a mounting cylinder 15. One end of the plug rod 18 is connected to the inner wall of the rear side of the metal frame 2, and one end of the mounting cylinder 15 is connected to the inner wall of the bottom groove 7.

[0041] A sealing ring 19 is embedded in the opening of the mounting cylinder 15, and a stopper rod 18 is slidably installed inside the sealing ring 19. A piston 17 is slidably installed inside the mounting cylinder 15 at one end of the stopper rod 18. The inner wall of the mounting cylinder 15 has symmetrically distributed oil grooves 16.

[0042] In this embodiment, under normal use, the aluminum alloy handle 3 is stored in the metal frame 2 embedded inside the front end of the refrigerator door 1. At this time, the surface of the refrigerator door 1 is flat and beautiful. When the user needs to open the refrigerator door 1, he presses the surface of the aluminum alloy handle 3 with his finger. Since the rear end of the aluminum alloy handle 3 is connected to the travel plate 6, and the bottom groove 7 at the lower end of the travel plate 6 is provided with a spring 13 between it and the inner wall of the rear end of the metal frame 2, in the initial stage of pressing, the aluminum alloy handle 3 drives the travel plate 6 to move backward against the elastic force of the spring 13. At the same time, the rotating shaft 11 on the upper inner wall of the metal frame 2 is supported by the torsional elasticity of the torsion spring 10, so that the outer wall of the rotating shaft 11 rotates through the connecting rod 14 and the fixed cylinder 9 at its lower end. The traveling rod 4 is slidably installed inside the fixed cylinder 9, and the lower end is provided with a connecting bead 5. During the pressing process, the traveling rod 4 will start to move along the pre-set assembly groove 8 in the metal frame 2.

[0043] The assembly slot 8 is an irregular triangular shape, containing a herringbone-shaped and interconnected starting slot 20 and return slot 21, as well as an outlet slot 23, an inlet slot 22 and a positioning slot 24 connected to the starting slot 20. The walking rod 4 starts from the starting slot 20 and is guided into the positioning slot 24 through the inlet slot 22 under the action of pressing. When it enters the positioning slot 24, the aluminum alloy handle 3 is positioned and stored inside the metal frame 2. Since the connection between the inlet slot 22 and the positioning slot 24 is provided with a cliff-shaped section, the walking rod 4 can be effectively prevented from moving in the opposite direction, thereby positioning the aluminum alloy handle 3 in the metal frame 2 and hiding it.

[0044] After use, the user presses the aluminum alloy handle 3 again. At this time, the walking rod 4, under the elastic force of the compression spring 25, disengages from the positioning groove 24 and is guided into the return groove 21 through the guide groove 23. The walking rod 4, inside the return groove 21, stops pulling on the travel plate 6. The elastic force of the spring 13 is released, causing the travel plate 6 and the aluminum alloy handle 3 to move out of the aluminum alloy handle 3 and return to the starting groove 20. Since the connection between the return groove 21 and the starting groove 20 is also provided with a cliff-shaped section, it is ensured that the walking rod 4 can only enter the starting groove 20 from the return groove 21 to achieve cyclic movement. At this time, it is easy to grip the aluminum alloy handle 3. It is worth noting that a gripping groove is opened at one end of the aluminum alloy handle 3, which makes it easy to apply force to the aluminum alloy handle 3. At this time, the user can easily grip the gripping groove on the aluminum alloy handle 3 to pull the refrigerator door 1 and complete the opening and closing operation.

[0045] Based on the principle of mechanical transmission and elastic reset, when the aluminum alloy handle 3 is pressed, the spring 13 is compressed and stores elastic potential energy. At the same time, the torsion spring 10 generates torsional elastic force, which provides power for subsequent reset. The walking rod 4 moves along a specific path in the assembly groove 8. It achieves unidirectional positioning and cyclic movement through the cliff-shaped cross section. The extension and retraction of the aluminum alloy handle 3 are controlled by the guiding function of the assembly groove 8. During the extension and retraction of the spring 13, the stop rod 18 slides in the mounting cylinder 15. The piston 17 squeezes the damping oil to flow through the oil groove 16, generating damping force, so that the spring 13 is reset smoothly, avoiding large wear on the stroke plate 6 and the aluminum alloy handle 3.

[0046] When stored, the surface of the refrigerator door 1 is flat, effectively preventing the handle extension from being bumped by external objects and preventing personal injury, thus ensuring safety. The concealed design prevents dust accumulation on the handle surface, reducing bacterial growth. Moreover, the appearance of the refrigerator door 1 is more concise and beautiful, improving the overall quality of the product. Users can extend and retract the aluminum alloy handle 3 simply by pressing, without complicated steps, making it convenient and quick to use. It solves the problems of traditional refrigerator door handles being exposed to the outside and easily damaged by bumps, accumulating dust and bacteria, and being unsightly. Through innovative structural design, the handle is concealed, which not only meets users' needs for refrigerator appearance and safety but also improves the practicality of the product.
