Description

Technical Field

[0001] The utility model relates to the technical field of connecting rods, in particular to a cross-groove outward-turned connecting rod structure based on a bottom shell. Background Art

[0002] Existing domestically sold split-body machines all use a sleeve to fix the air guide plate. The specific operation method is to hold the connecting rod with one hand and pick up the sleeve with the other hand and push it to the left. However, there is a fixed structure on the head of the sleeve, and it may not be able to be locked into place all at once during the locking process. The sleeve needs to be rotated to make its structure match the connecting rod structure completely. A "click" sound is heard, which indicates that the card is installed in place. This fixing method wastes manpower and material resources and is inefficient.

[0003] This design is a new connecting rod structure with a cross slot turned outward. The specific operation method is to pinch the cross slot head of the connecting rod, align it with the hole of the right wind deflector bracket and insert the cross slot head into the hole, then release your hand, and its head will automatically unfold and be fixed on the bracket, which can replace the shaft sleeve to fix the wind deflector on the bottom shell. Eliminating the shaft sleeve can not only reduce costs, but also reduce the number of people who install the shaft sleeve, and at the same time improve efficiency. Utility Model Content

[0045] The working principle of this utility model:

[0046] The cross slot outward-turned connecting rod structure of the utility model is an innovative mechanical design, which optimizes the structure of the bottom shell by setting a special cross slot on the bottom shell of the air conditioner and cooperating with the outward-turned connecting rod. The main purpose of this design is to improve the stability and reliability of the air conditioner, while reducing production costs and maintenance difficulties.

[0047] Implementation case 1:

[0048] like Figure 1-7 A cross slot outward-turned connecting rod structure based on a bottom shell is shown, including a cross slot 1, one end of the cross slot 1 is connected to a wind sweeping connecting rod 2, and the other end of the cross slot 1 is connected to an air guide plate bracket, and the air guide plate bracket is provided with a bracket hole. The cross slot 1 includes a slot opening 3, a slot bottom 4 and a slot wall 5, the slot bottom 4 is connected to the slot wall 5, and the slot opening 3 is the opening part of the slot wall 5.

[0049] The bracket holes are circular holes, and elastic buckles are provided on the bracket holes. The cross slot 1 passes through the bracket holes of the air deflector bracket and is connected by being pressed or embedded by the buckles. The cross slot 1 is provided with a horizontal and a vertical notch 3, and these two notches 3 intersect perpendicularly to form a cross-shaped opening. The number of slot walls 5 is four, and the four slot walls 5 of the cross slot 1 are slightly enlarged to form a locking point. The cross slot 1 is made of an elastic material such as polycarbonate or nylon. The air deflector bracket is connected to the air deflector 6, and the air deflector 6 is made of plastic. The sweeping link 2 is connected to the air deflector shaft through an internal pin to fix the windshield of the split indoor unit. The sweeping link 2 controls the adjustment speed and range of the wind direction through the rotation speed and torque provided by the motor. The air deflector bracket adopts an arc-shaped or zigzag shape and is made of metal or plastic. A locking structure is provided on the air deflector bracket, and after the angle of the air deflector is adjusted, it is fixed through the locking structure.

[0050] Design a connecting rod with an everted cross-slot structure, send the drawings to the manufacturer through procurement to make some samples, and first apply it to relatively simple casings such as the F1 split Tianli series to verify whether there are any abnormalities in the assembly. Verify 6 units on the trial production line, including whether it is easy to pinch the cross-slot, whether there is a risk of being pinched off, whether it can be easily unfolded when the hand is released, whether it can be tightly clamped on the bracket after unfolding, whether it will become loose when pulled after being clamped, and whether the air deflector can rotate normally, etc. Optimize the connecting rod drawing dimensions according to the assembly situation.

[0051] After there are no abnormalities in the assembly, send 2 units to the packaging laboratory to test the drop test, verify whether the connecting rod will crack after dropping, whether the cross-slot will break, and whether the air deflector is scratched, etc. Optimize the assembly process according to the experimental situation; after there are no abnormalities in the experiment, 10 units can be put into small batches on the general assembly line to verify whether the cross-slot is easy to clamp during the line flow, whether the overall efficiency is improved, and how much it can be improved; after the assembly is completed, send 2 units to the packaging laboratory to verify the consistency of the drop test again.

[0052] If there are no abnormalities in both the assembly and experimental verification, the drawings can be sent to the headquarters first, and the verification results can be sent together for the headquarters to evaluate the feasibility, and promote the headquarters to optimize the drawings, issue new codes and synchronously change the details to update the guiding documents; it takes a cycle for the headquarters to make changes. After reporting to the headquarters and obtaining consent, continue to ramp up the volume for verification of 500 units and 2000 units.

[0053] After the F1 split is mature, a suitable cross-slot connecting rod can be designed according to the air deflector structures of relatively difficult casings such as the F2 split and J split to achieve the effect of fully switching the split indoor units for domestic sales. This fixing method can not only improve the production efficiency of the split indoor units for domestic sales, but also reduce the number of employees, lower the product production cost, and improve the market competitiveness of the product.

[0054] Implementation Case Two:

[0055] In this embodiment, Figure 1-7 The cross slot outward-turned connecting rod structure based on the bottom shell shown has the same technical means as the cross slot outward-turned connecting rod structure of the implementation case 1.

[0056] The design of the cross groove 1 in this embodiment makes better use of the internal space of the bottom shell, which is conducive to air circulation, thereby improving the cooling or heating efficiency of the air conditioner. Secondly, the outward-turning mechanism of the wind-sweeping connecting rod 2 increases the stability of the structure to a certain extent, so that the product can better resist external impacts and vibrations, and extend the service life of the product. In terms of environmental protection, this structure also performs well. Since it reduces the use of materials and the modular design facilitates future disassembly and recycling, it is more in line with the trend of sustainable development. The cross-slot outward-turned connecting rod structure based on the bottom shell of the air conditioner has an innovative design that not only improves the assembly efficiency and performance of the product, but also achieves effective cost control and contributes to environmental protection.

[0057] Implementation case three:

[0058] In this embodiment, Figure 1-7 The cross slot outward-turned connecting rod structure based on the bottom shell shown has the same technical means as the cross slot outward-turned connecting rod structure of the implementation case 1.

[0059] The core of the cross-slot outward-turning connecting rod structure lies in its unique "cross-slot" design. In the center of the bottom shell, there is a horizontal and a longitudinal slot, which are staggered vertically to form a cross shape. This design makes the inner and outer machines more closely connected, and at the same time can effectively disperse the stress caused by gravity and operation, greatly improving the reliability of the structure. Next is the setting of the outward-turning connecting rod. Unlike the direct connection method in traditional structures, the outward-turning connecting rod adopts a retractable design. When the connecting rod is stretched, it will flip outward, thereby driving the bottom shell to expand to both sides to form a stable support platform. This not only increases the stability of the structure, but also makes the entire device more adaptable and can adapt to installation spaces of different widths.

[0060] The main functions of this utility model:

[0061] The design of this structure of the utility model includes a quick disassembly and assembly mechanism. Through simple buckles or knobs, users or technicians can easily complete the assembly or disassembly work, which greatly saves time and labor. The cross-slot outward-turned connecting rod structure not only has a breakthrough in practicality, but also has a beautiful appearance design. The smooth lines and exquisite craftsmanship show the aesthetic characteristics of modern industrial design, and perform well in improving equipment stability, simplifying the operation process, and enhancing aesthetics.
