Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a door and window handle structure. Background Art

[0002] At present, in order to facilitate the opening and closing of aluminum alloy doors and windows, handles are mostly set on the doors and windows to facilitate the opening and closing of the doors and windows. Among them, there are two ways to install handles, which are:

[0003] The first method is to screw the threaded end of the screw through the handle and screw it onto the aluminum alloy frame of the door and window sash. Since the aluminum alloy frames on aluminum alloy doors and windows are thin-walled components, the amount of screw connection is very limited, which can easily lead to limited stability of the screw locking, and the handle is prone to loosening after a period of use.

[0004] The second method is to pass the threaded end of the screw through the aluminum alloy frame of the door and window sash and then screw it onto the handle. Since the screw passes through the aluminum alloy frame, the entire screw needs to be removed every time the handle is replaced in order to remove the handle. The screw removal process is relatively cumbersome, and more than two screws are generally used to fix the handle when the handle is actually installed, which easily leads to low efficiency in replacement and maintenance of the handle.

[0005] Therefore, it is very necessary to redesign the structure of door and window handles. Utility Model Content

[0023] like Figure 1 and Figure 2As shown, a door and window handle structure described in the utility model includes a hand-pull portion 1, a front clamping piece 2, a rear clamping strip 3, and a connecting piece 4, wherein the hand-pull portion 1 is arranged on the front wall of the front clamping piece 2, and the two ends of the connecting piece 4 are respectively connected to the rear end of the front clamping piece 2 and the middle part of the rear clamping strip 3, and a clamping groove 10 is formed between the two ends of the rear clamping strip 3 and the front clamping piece 2, and the two ends of the rear clamping strip 3 are respectively screwed with a clamping screw 5 that can be screwed into the corresponding clamping groove 10.

[0024] In the door and window handle structure, not only can the clamping groove 10 be used to achieve the clamping positioning effect, but also the two clamping screws 5 can be used to achieve a fast and stable positioning effect. In addition, the rear clamping strip 3 is in a strip shape, which can be easily embedded and rotated, so that it can be quickly and stably installed, and it is not easy to get loose after long-term use. When disassembling the door and window handle structure, it only needs to loosen the clamping screw 5, and then disassembly can be achieved. Its disassembly and replacement are very convenient, which can greatly improve the efficiency of handle replacement and maintenance.

[0025] like Figure 1 and Figure 2 As shown, the handle portion 1 includes a disc portion 11 and a cylindrical portion 12, and the two ends of the cylindrical portion 12 are respectively connected to the front wall of the front clip 2 and the middle of the rear wall of the disc portion 11. Such a handle portion 1 is very simple and reliable, which is not only convenient for manufacturing, but also convenient for users to hold it from different angles, so that it is convenient for different users to use, thereby helping to further improve the applicability of the door and window handle structure.

[0026] like Figure 1 and Figure 2 As shown, a clearance gap 20 for fingers to enter is reserved between the disc portion 11 and the front clip 2. This makes it convenient for fingers to act on the disc portion 11, thereby helping to improve the convenience of use.

[0027] like Figure 1 As shown, the outer circumferential surface of the disc portion 11 is a first arc surface 111 connected to the end surfaces of the two ends thereof by arc transition. The first arc surface 111 connected by arc transition can avoid sharp corners at the finger contact point, thereby greatly reducing the discomfort of the finger contacting the disc portion 11, and making the finger contact more comfortable.

[0028] like Figure 1 and Figure 2 As shown, the front clip 2 is a disc-shaped clip-on cover, and the end of the cylindrical portion 12 is connected to the middle of the front wall of the front clip 2. This not only enables the front clip 2 to have a high structural strength, but also enables the front clip 2 to have a better covering effect, and can ensure that the door and window handle structure is very coordinated after installation, which can reduce the complexity of installation.

[0029] Since the front clip 2 is a disc-shaped clip cover, it can cover the hole on the door and window sash through which the rear clip 3 passes. In addition, during the installation process, no matter in which direction the door and window handle structure rotates and how much it rotates, the door and window handle structure will not be skewed when viewed from the outside, thereby ensuring that the door and window handle are in perfect harmony, thereby reducing the complexity of installation.

[0030] like Figure 1 As shown, the outer circumferential surface of the front clip 2 is a second arc surface 21 connected to the end surfaces of the two ends thereof by arc transition. In this way, sharp corners can be avoided on the edges and corners of the front clip 2, thereby reducing the discomfort of finger contact, and thus ensuring that the use is very comfortable. In addition, the second arc surface 21 connected by arc transition can make the card slot 10 smoothly carded to the corresponding position when the door and window handle structure is rotated to complete the card slot 10, thereby facilitating the convenience of installation.

[0031] like Figure 1 and Figure 2 As shown, the rear clamping strip 3 is a waist-shaped body, and the connecting piece 4 is a cylinder. This is not only conducive to the manufacture of the rear clamping strip 3 and the connecting piece 4, but also improves the reliability of the door and window handle structure and facilitates the installation of the door and window handle structure.

[0032] like Figure 1 As shown, the outer circumferential surface of the rear clamping strip 3 is a third arc surface 31 connected to the end surfaces of the two ends thereof by arc transition. The third arc surface 31 connected by arc transition can smoothly clamp the clamping slot 10 to the corresponding position when the door and window handle structure is rotated to complete the clamping slot 10, thereby improving the convenience of installation.

[0033] like Figure 1 and Figure 2 As shown, the clamping screw 5 is a set screw, which can not only achieve a reliable clamping effect, but also avoid using an overly thick rear clamping strip 3, thereby helping to control the manufacturing difficulty of the door and window handle structure.

[0034] like Figures 3 to 6 As shown, when the door and window handle structure needs to be installed on the door and window leaf 100, a through waist-shaped hole 102 is first opened on the cover plate 101 of the door and window leaf 100; then the rear clamping strip 3 is passed through the waist-shaped hole 102; then it is rotated (by pressing Figure 4 The door and window handle structure is rotated in the manner shown by the arc arrow in the middle) so that the two card slots 10 are carded on the cover plate 101; then the two clamping screws 5 are tightened with an inner hexagonal wrench; this completes the installation of the door and window handle structure, which is very convenient and stable to install, and it is not easy to get loose after long-term use. When the door and window handle structure needs to be disassembled, first loosen the two clamping screws 5 with an inner hexagonal wrench; then rotate (press Figure 4The door and window handle structure is rotated in the manner indicated by the arc arrow in the middle, so that the card slot 10 is separated from the cover plate 101, and the rear clamping strip 3 is directly opposite to the opening of the waist-shaped hole 102; then pull (press Figure 5 and Figure 6 The door and window handle structure can be quickly disassembled by pulling the door and window handle structure in the moving manner shown by the straight arrow in the middle so that the rear clamping strip 3 passes through the waist-shaped hole 102; it is very convenient to disassemble, which can greatly improve the efficiency of handle replacement and maintenance.

[0035] like Figures 3 to 6 As shown, the rear clamping strip 3 is completely located behind the front clamping piece 2, the front clamping piece 2 completely covers the waist-shaped hole 102, the front clamping piece 2 and the rear clamping strip 3 are respectively pressed on the front and rear walls of the cover piece 101, and the clamping screw 5 is tightly pressed on the rear wall of the cover piece 101. This can ensure that the installation and positioning of the door and window handle structure is very stable and reliable.
