[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figures 1-5 The present invention includes an arc-shaped handle body 1. Arc-shaped reinforcing plates 2 are connected to both inner side walls of the arc-shaped handle body 1. The arc-shaped reinforcing plates 2 serve both to enhance the structural strength of the arc-shaped handle body 1 and as a positioning base for the connector 4. Positioning slots 3 are provided on the upper and lower sides of opposite sides of the two arc-shaped reinforcing plates 2 to cooperate with elastic pins 7 to fix the connector 4. Connectors 4 are provided on both the upper and lower sides of the interior of the arc-shaped handle body 1. Slots 5 are provided on both sides of the connector 4. The slots 5 on both sides movably engage with the arc-shaped reinforcing plates 2 on both sides to achieve initial assembly of the connector 4 with the arc-shaped handle body 1. Both sides of one end of the connector 4... A pin hole 6 is provided, and an elastic pin 7 is inserted into the pin hole 6. A through groove 8 is provided on one side wall of the slot 5 corresponding to the extension line segment of the pin hole 6. When the connector 4 is assembled with the arc-shaped rib plate 2 through the slot 5, one end of the elastic pin 7 passes through the positioning slot 3 of the arc-shaped rib plate 2 and extends into the through groove 8 to form a tight fit and fixation, preventing the connector 4 from shifting. After the connector 4 is assembled with the arc-shaped rib plate 2 through the slots 5 on both sides, one end of the elastic pin 7 passes through the positioning slot 3 on the arc-shaped rib plate 2 and is located in the through groove 8 to realize the installation of the connector 4. Decorative parts 9 are snapped onto both the upper and lower ends of the arc-shaped handle body 1, and the lower end of the decorative parts 9 is snapped onto the connector 4.

[0025] One end of the connector 4 has two fixing holes 10, and the other end of the connector 4 has two internal hexagonal holes 11. The two internal hexagonal holes 11 are connected to the two fixing holes 10 respectively. The internal hexagonal holes 11 are fitted with anti-loosening nuts 12. By cooperating with the fixing holes 10 and the anti-loosening nuts 12, the handle can be firmly connected to the furniture cabinet body to prevent the screws from loosening. The upper end of the connector 4 has a convex groove 13. The lower end of the decorative part 9 is engaged with the convex groove 13. The decorative part 9 is used to cover the internal structure and improve the appearance.

[0026] The lower middle part of the decorative part 9 is connected to a hook 14, which engages with the convex groove 13. Side latches 15 are connected to both sides of the lower end of the decorative part 9, and a rear latch 16 is connected to the rear side of the lower end of the decorative part 9.

[0027] The connector 4 and decorative part 9 are made of plastic, while the arc handle body 1, arc rib plate 2, anti-loosening nut 12 and elastic pin 7 are made of metal. The combination of plastic and metal not only ensures structural strength, but also eliminates abnormal noise when metal parts are loose through the buffering effect of plastic.

[0028] The plastic connector 4 can buffer the vibration and friction between the metal arc-shaped rib plate 2 and the connector 4, and avoid the abnormal noise caused by direct contact between metal and metal; the plastic decorative part 9 can also avoid the noise caused by the collision between the end of the metal arc-shaped handle body 1 and external objects.

[0029] Working principle:

[0030] Connector 4 is assembled and fixed to the arc-shaped handle body 1:

[0031] First, align the slots 5 on both sides of the connector 4 with the arc-shaped rib plate 2 that is fixedly connected to the inner two side walls of the arc-shaped handle body 1, and slide the connector 4 along the arc-shaped trajectory of the arc-shaped rib plate 2 until it slides to the preset assembly position.

[0032] When the connector 4 is in place, the pin holes 6 on both sides of one end will align with the pre-set positioning slots 3 on the arc-shaped rib plate 2. The elastic pin 7 is inserted from one end of the pin hole 6, and one end can pass smoothly through the positioning slot 3 and eventually extend into the through slot 8 opened through the side wall of the slot 5.

[0033] In this way, the two ends of the elastic pin 7 are respectively locked in the pin hole 6 and the through groove 8, which restricts the sliding or disengagement of the connector 4 along the arc-shaped rib plate 2, and completes the rigid fixation of the connector 4 and the arc-shaped handle body 1.

[0034] The handle is securely attached to the furniture.

[0035] At the end of the connector 4 away from the pin hole 6, the anti-loosening nut 12 is pre-installed in the internal hexagonal hole 11. The internal hexagonal hole 11 and the fixing hole 10 at the other end of the connector 4 are coaxially connected to ensure that the anti-loosening nut 12 is aligned with the fixing hole 10.

[0036] Then take a screw of the appropriate size, pass one end of the screw through the preset mounting hole of the furniture cabinet (such as wardrobe or cabinet door panel), then through the fixing hole 10 of the connector 4, and finally form a threaded connection with the anti-loosening nut 12 in the internal hexagon hole 11.

[0037] When tightening the screw, the internal hexagonal hole 11 can restrict the lock nut 12 from rotating synchronously with the screw, ensuring that the screw and the lock nut 12 are tightly engaged; at the same time, the lock nut 12's own anti-loosening structure (such as anti-slip texture and elastic washer characteristics) can offset the impact of furniture opening and closing vibration on the screw during long-term use, prevent the screw from loosening, and achieve a firm connection between the handle and the furniture cabinet.

[0038] Snap-fit ​​assembly and functional implementation of decorative component 9:

[0039] Take the decorative piece 9 and align it with the upper and lower end faces of the arc-shaped handle body 1. Align the hook 14 at the lower middle of the decorative piece 9 with the convex groove 13 at the upper end of the connector 4. Press the decorative piece 9 vertically towards the convex groove 13 until the hook 14 is fully inserted into the convex groove 13 to form a longitudinal fixation.

[0040] During the pressing process, the side locking blocks 15 on both sides of the lower end of the decorative part 9 will fit against the corresponding side wall of the connector 4 and undergo slight deformation, eventually locking into the side wall of the connector 4 to form a lateral fixation; at the same time, the rear locking block 16 on the rear side of the lower end of the decorative part 9 will fit against the rear end of the connector 4 to form a front-back fixation.

[0041] Through the multi-directional engagement of the hook 14, side latch 15, rear latch 16 and convex groove 13, the decorative part 9, the connector 4, and the arc handle body 1 are tightly fixed, which not only covers the internal assembly structure such as the pin hole 6 and the internal hexagonal hole 11, improving the integrity of the handle's appearance, but also helps to limit the slight displacement of the connector 4, enhancing the overall structural stability.

[0042] In addition, since the connector 4 and decorative part 9 are made of plastic, while the curved handle body 1, curved rib plate 2, anti-loosening nut 12 and elastic pin 7 are made of metal, in daily use, when the hand holds the curved handle body 1 and applies force, the plastic connector 4 can buffer the vibration and friction between the metal curved rib plate 2 and the connector 4, and avoid the abnormal noise caused by direct contact between metal and metal.

[0043] Furthermore, the plastic decorative part 9 can also prevent noise generated by the collision between the end of the metal curved handle body 1 and external objects, while also being lightweight and wear-resistant, thus extending the overall service life of the handle.
