Detailed Implementation

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0029] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0030] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0031] like Figures 1 to 10As shown in the embodiment of this utility model, a cabinet door handle includes a handle 1 and connecting blocks 2 located at both ends of the handle 1 in the X direction for connecting to the cabinet door. The connecting blocks 2 are hollow structures, and a connecting post 21 located inside the connecting block 2 is connected to the inner cavity of the connecting block 2. A threaded connector 3 is provided through the inner cavity of the connecting post 21. One end of the threaded connector 3 passes through the inner cavity of the connecting post 21 and is threadedly connected to the handle 1, while the other end is limited to the inner cavity of the connecting post 21.

[0032] This design allows for detachable assembly of the grip and connecting block via a threaded connector and connecting post. Both components can be processed separately and then reassembled to obtain the finished product, reducing manufacturing complexity. Furthermore, the hollow structure of the connecting block reduces material consumption and saves production costs. The other end of the threaded connector can be positioned within the connecting post's inner cavity either by machining a limiting step or by forming a threaded connection.

[0033] A positioning plate 22 extends from the upper end of the side plate of the connecting block 2 near the upper end of the grip 1 in the X direction. A first positioning groove 23 is formed between the positioning plate 22 and the top of the other side plates of the connecting block 2, which is adapted to the shape of both ends of the grip 1. Both ends of the grip 1 fit into the first positioning groove 23 on the adjacent side.

[0034] With this setting, the first positioning groove positions and limits the connection between the connecting block and the grip in the X direction during installation, making installation more convenient. At the same time, after installation, the cooperation between the first positioning groove and the grip makes the connection between the connecting block and the grip more stable.

[0035] The handle 1 has a second positioning groove 11 at both ends corresponding to one side of the connecting block 2. The second positioning groove 11 fits into the connecting block 2 on the adjacent side.

[0036] With this setting, the second positioning groove, in conjunction with the first positioning groove, positions and limits the connection between the connecting block and the grip bar in the lateral direction during installation, preventing them from moving in the X direction. At the same time, after installation, the connection between the connecting block and the grip bar is more stable.

[0037] The grip 1 is a hollow structure, and a support connecting block 12 is connected between the upper and lower end faces of its inner cavity. The support connecting block 12 extends along the X direction and divides the inner cavity of the grip 1.

[0038] This design ensures that the grip is hollow, reducing weight and material consumption, while the support connecting block maintains its strength and is easy to manufacture. It can be obtained by molding or by turning two chambers.

[0039] The upper end of the connecting column 21 is provided with a limiting groove 25 that is adapted to the shape of the supporting connecting block 12 and forms an interlocking fit. The limiting groove 25 limits the supporting connecting block 12 on both sides in the Y direction.

[0040] With this setting, the limiting groove positions the grip bar in the Y direction through the supporting connecting block, and cooperates with the first positioning groove and the second positioning groove to make the horizontal positions of the connecting block and the grip bar relatively determined.

[0041] The support connecting block 12 is provided with a threaded hole 121, and one end of the threaded connector 3 passes through the inner cavity of the connecting column 21 and is connected to the threaded hole 121.

[0042] This design, with the threaded hole located in the support connecting block, improves the stability of the connection between the grip and the connecting block.

[0043] The support connecting block 12 includes a first support block 122 and a second support block 123 connected sequentially from top to bottom. The lower end face of the first support block 122 is provided with a positioning groove 124 extending in the X direction, and the center of the threaded hole 121 is located on the positioning groove 124.

[0044] This configuration allows for the machining of the positioning groove before the threaded hole. The positioning groove provides a positioning function for the threaded hole, preventing deviations in its machining position. In this embodiment, the upper end of the second support block is connected to one side of the positioning groove at the lower end of the first support block, further facilitating machining and making turning easier. The term "from top to bottom" in this application is defined as the direction from the distance away from the connecting block to the distance towards the connecting block.

[0045] The connecting post 21 is located at the center of the inner cavity of the connecting block 2, and at least one connecting plate 24 is connected between its outer periphery and the inner cavity of the connecting block 2.

[0046] In this embodiment, there are two connecting plates, located at the inner ends of the two opposite side plates of the connecting block. This arrangement ensures a hollow structure, improves the strength of the connecting block, and facilitates processing.

[0047] The threaded connector 3 includes, from top to bottom, a first threaded portion 31, a second post portion 32, and a third post portion 33, which are concentrically arranged and connected in sequence. The inner cavity of the connecting post 21 includes, from top to bottom, a first hole portion 211 and a second hole portion 212, which are concentrically arranged and connected. The diameter of the second hole portion 212 is larger than the diameter of the first hole portion 211, and a first limiting step 213 is formed between the two.

[0048] The second column portion 32 is located inside the first hole portion 211 and its outer diameter is adapted to the hole diameter size of the first hole portion 211. The first threaded portion 31 passes through the connecting column 21 and is threadedly connected to the handle 1. The outer diameter of the third column portion 33 is larger than the outer diameter of the second column portion 32, and the first limiting step 213 and the upper end annular surface of the third column portion 33 form an abutting limiting fit.

[0049] This design further enhances the ease of assembly and disassembly of the structure. In this embodiment, a threaded hole is also machined at the bottom center of the third column to facilitate connection with the cabinet door.

[0050] The top of the positioning plate 22 is flush with the top surface of the grip 1 and forms a first connecting plane. A decorative plate 4 is connected to the upper end of the grip 1. The decorative plate 4 has the same size as the first connecting plane.

[0051] The decorative panel can be made of materials such as acrylic or crystal panel to enhance its decorative appeal and grip. The connection method between the decorative panel and the first connecting surface can be adhesive, welding, etc.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
