[0004] However, this patent still has shortcomings. While it improves tensile strength during use, it lacks a clear installation structure. Traditional screw installation requires precise drilling, alignment of screw holes, and tightening, a cumbersome process prone to deviation and inconvenient for replacement. Welding requires specialized equipment, and damaged handles cannot be easily repaired. Furthermore, the overall handle structure occupies storage space, hindering transportation and storage. Therefore, those skilled in the art have provided a folding aluminum alloy handle for refrigerators to address the problems mentioned in the background. Utility Model Content

[0005] 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 a folding aluminum alloy handle for a refrigerator, comprising an aluminum alloy handle body and a refrigerator door. The aluminum alloy handle body is located on the front side of the refrigerator door, and symmetrically distributed mounting grooves are provided at the front end of the refrigerator door. The aluminum alloy handle body includes an upper mounting rod, a middle mounting rod, and a lower mounting rod. A slot communicating with the mounting grooves is provided inside the front end of the refrigerator door. A mating plate that slides into the slot is provided at one end of both the upper and lower mounting rods. A positioning groove is provided at the lower end of the middle mounting rod, and a positioning post that slides into the positioning groove is provided at the upper end of the lower mounting rod. A spring is provided between the positioning post and the positioning groove.

[0008] Furthermore, the lower end of the upper mounting rod is provided with a slot, and the upper end of the middle mounting rod is provided with an insert rod that is slidably installed inside the slot. A tie rod is provided between the insert rod and the slot.

[0009] Specifically, the insert rod is inserted into the slot, allowing the upper mounting rod and the middle mounting rod to be installed together. The tie rod is connected to the insert rod, so that the upper mounting rod and the middle mounting rod, which are not installed together, are reconnected by the elasticity of the tie rod, preventing them from completely detaching. The upper mounting rod and the middle mounting rod can be folded.

[0010] Furthermore, the inner wall of the mounting groove is provided with symmetrically distributed docking strips, and the rear end of each docking plate is provided with symmetrically distributed docking grooves that slide with the docking strips;

[0011] Specifically, the mating plate is engaged with the mating groove by mating strips and mating grooves inside the mounting groove. After installation, the mating plate is laterally limited and can only slide longitudinally, thus improving the stability of the mating plate after installation.

[0012] Furthermore, the upper end of the lower mounting rod is provided with a spring that is sleeved on the outside of the positioning post, and a sleeve is provided above the spring. The inner wall of the sleeve and the outer wall of the lower end of the middle mounting rod are both provided with threads for installation.

[0013] Specifically, the elastic force of spring one acts on the sleeve to prevent the threaded sleeve and the central mounting rod from loosening.

[0014] Furthermore, a ring seat is provided at the upper end of the spring, and a rotating ring is rotatably sleeved on the outer wall of the ring seat, with the upper end of the rotating ring connected to the sleeve;

[0015] Specifically, the sleeve is rotatably installed by rotating the ring and the ring seat to avoid the spring from hindering the rotation of the sleeve, so that the sleeve rotates above the spring, and the elastic force of the spring is effectively applied to the sleeve.

[0016] Furthermore, the inner wall of the lower end opening of the slot is provided with an inner chamfer, the outer wall of the upper end of the insertion rod is provided with an outer chamfer, and the outer sides of the upper mounting rod, middle mounting rod and lower mounting rod are fitted with cloth sleeves, and the outer and inner walls of the cloth sleeves are provided with male hook and loop fasteners and female hook and loop fasteners.

[0017] Specifically, the inner and outer chamfers make it easier for the insert and slot to be inserted, and the connection structure between the upper, middle and lower mounting rods is covered by a cloth cover, while improving the grip comfort of the upper, middle and lower mounting rods.

[0018] Beneficial effects

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

[0020] In this invention, the aluminum alloy handle body is installed on the inner front wall of the refrigerator door via a connecting plate. The aluminum alloy handle body is adjusted to a multi-segment structure consisting of an upper mounting rod, a middle mounting rod, and a lower mounting rod. The upper mounting rod and the middle mounting rod are longitudinally elastically supported by springs. Under the action of the elastic force of the second spring, the two support plates move into the slot communicating with the connecting groove through the back-relaxation extrusion force exerted by the second spring on the upper mounting rod and the lower mounting rod. This limits and fixes the aluminum alloy handle body composed of the upper mounting rod, the middle mounting rod, and the lower mounting rod. During disassembly, an extrusion force is applied to the mounting rod and the middle mounting rod, causing the connecting plate to move out of the slot, thus realizing the convenient disassembly of the aluminum alloy handle body.

[0021] Furthermore, during storage, the upper mounting rod can be detached from the middle mounting rod and folded, reducing the overall length of the aluminum alloy handle body, reducing storage space, and facilitating transportation and storage.

[0022] 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

[0037] 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.

[0038] Example

[0039] Please see Figures 1-8As shown, this embodiment is a folding refrigerator aluminum alloy handle, including an aluminum alloy handle body 1 and a refrigerator door 5. The aluminum alloy handle body 1 is provided on the front side of the refrigerator door 5. The front end of the refrigerator door 5 has symmetrically distributed mounting grooves 6. The aluminum alloy handle body 1 includes an upper mounting rod 101, a middle mounting rod 102 and a lower mounting rod 103. The front end of the refrigerator door 5 has a slot 7 that communicates with the mounting groove 6. One end of the upper mounting rod 101 and the lower mounting rod 103 is provided with a docking plate 3 that slides into the slot 7. The lower end of the middle mounting rod 102 has a positioning groove 21. The upper end of the lower mounting rod 103 has a positioning post 20 that slides into the positioning groove 21. A spring 21 is provided between the positioning post 20 and the positioning groove 21.

[0040] The upper mounting rod 101 has a slot 12 at its lower end, and the middle mounting rod 102 has an insert rod 14 that is slidably installed inside the slot 12 at its upper end. A tie rod 13 is provided between the insert rod 14 and the slot 12.

[0041] The inner wall of the mounting groove 6 is provided with symmetrically distributed docking strips 4, and the rear end of the docking plate 3 is provided with symmetrically distributed docking grooves 19 that slide with the docking strips 4.

[0042] The upper end of the lower mounting rod 103 is provided with a spring 9 that is sleeved on the outside of the positioning post 20. A sleeve 8 is provided above the spring 9. The inner wall of the sleeve 8 and the outer wall of the lower end of the middle mounting rod 102 are both provided with threads 10 for installation.

[0043] A ring seat 17 is provided at the upper end of the spring 9, and a rotating ring 18 is rotatably sleeved on the outer wall of the ring seat 17. The upper end of the rotating ring 18 is connected to the sleeve 8.

[0044] The inner wall of the lower end opening of the slot 12 is provided with an inner chamfer 16, the outer wall of the upper end of the insertion rod 14 is provided with an outer chamfer 15, and the upper mounting rod 101, the middle mounting rod 102 and the lower mounting rod 103 are sleeved with a cloth sleeve 2. The outer wall and the inner wall of the cloth sleeve 2 are provided with male hook and loop fasteners and female hook and loop fasteners.

[0045] In this embodiment, the insert 14 at the upper end of the middle mounting rod 102 is inserted into the slot 12 of the upper mounting rod 101, connecting the upper mounting rod 101 and the middle mounting rod 102. A relative compressive force is applied to the upper mounting rod 101 and the lower mounting rod 103, causing the spring 11 to contract. The operator first aligns the mating plate 3 of the lower mounting rod 103 and the upper mounting rod 101 with the pre-set mounting groove 6 on the refrigerator door 5, and pushes it longitudinally along the guide structure of the mating strip 4 and the mating groove 19, so that the mating plate 3 completely slides into the slot 7. At this point, the pressure on the upper mounting rod 101 and the lower mounting rod is released. The extrusion pressure of 103 causes the positioning pin 20 to automatically embed into the positioning groove 21 under the elastic force of spring 11, simultaneously completing the longitudinal locking of the lower mounting rod 103 and the middle mounting rod 102. Finally, the sleeve 8 is rotated, and the middle mounting rod 102 is fastened to the sleeve 8 through the thread 10 connection. Spring 9, through the rotation support structure of ring seat 17 and rotating ring 18, always applies axial pressure to the sleeve 8 to prevent the thread 10 from loosening and to avoid the spring 11 from shrinking during use. The entire installation process does not require tool drilling or welding, only linear pushing and rotation operations, improving installation efficiency.

[0046] In use, the three-section aluminum alloy rod body is rigidly connected by a double locking mechanism. The docking plate 3 and the slot 7 form the main load-bearing structure. The cone surfaces of the positioning column 20 and the positioning slot 21 cooperate to form a mechanical limit to prevent lateral displacement. The cloth cover 2 wraps around the joint area with the hook and loop fasteners, which not only conceals the mechanical structure but also improves the grip comfort.

[0047] During disassembly and maintenance, the sleeve 8 rotates to disengage from the threaded connection 10. A compressive force is applied between the upper mounting rod 101 and the lower mounting rod 103, causing the spring 11 to contract. At this point, the mating plate 3 is pulled out of the slot 7 and removed through the mounting groove 6, allowing the entire handle assembly to be removed as a whole. Simultaneously, the insertion rod 14 moves out of the slot 12, and the middle mounting rod 102 and the upper mounting rod 101 fold. The tie rod 13 maintains the elastic extension of the connecting section under pre-tension, forming a bendable hinge structure. During storage and transportation, the upper mounting rod 101 can rotate 180° around the axis of the insertion rod 14. The tension bar 13 provides reverse tension to prevent excessive folding, reducing the overall length after folding. Combined with the flexible wrapping of the cloth cover 2, multiple handles can be stacked, improving the utilization rate of storage volume. The spring energy storage mechanism ensures that the handles automatically return to the working state after unfolding, avoiding structural loosening caused by transportation vibration. It solves the problems of cumbersome installation, difficult maintenance, and large space occupation of traditional handles. The snap-fit ​​installation structure eliminates the dependence on the precision of screw fixing. The modular folding design achieves a balance between functionality and portability, making it particularly suitable for cold chain transportation scenarios that require frequent changes of handle styles or have limited space.
