Description
Technical Field
[0001] This utility model belongs to the technical field of door and window accessories, and specifically refers to an adjustable hook for doors and windows. Background Technology
[0002] In modern architecture, especially in residences in Europe and America, hook mounting slots are commonly installed at the top of windows. These slots provide a convenient base for hanging curtains. The common method of hanging curtains involves inserting the two ends of the curtain rod into the mounting slots using specialized hooks, thus securing and supporting the rod. To accommodate windows of different widths, telescopic curtain rods are widely used in the market. These rods typically consist of two or more sliding tubes, allowing users to adjust the total length of the rod according to the actual width of the window. The curtains themselves have mounting holes evenly spaced along the top edge of the fabric. During installation, the telescopically adjustable curtain rod passes through these holes, allowing the curtains to slide smoothly along the rod.
[0003] However, the wall thickness of the mounting grooves for hooks varies significantly across different construction projects and environments. Hooks used for fixing may not be able to clamp effectively, reducing installation reliability. Traditional hooks use shims for clamping, but this increases installation difficulty and makes assembly challenging for users. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 4 :
[0033] An adjustable hook for doors and windows includes a hook base 1. The front side of the hook base 1 is provided with a hook 2 for supporting the end of a curtain rod. The top of the hook base 1 is formed with an adjustment panel 10. The adjustment panel 10 is provided with several parallel limiting protrusions 11, which extend along the front-back direction of the adjustment panel 10. The top of the adjustment panel 10 is covered with a spring piece 3. The bottom of the spring piece 3 is provided with a limiting protrusion 31 that cooperates with the limiting protrusions 11 for locking. The top of the spring piece 3 is covered with a pressure cover 4, and the bottom of the pressure cover 4 abuts against the upper end face of the spring piece 3. The pressure cover 4 covers the spring piece 3 by sliding. The rear end of the spring piece 3 is provided with a downwardly extending locking edge 30. The locking edge 30 and the rear end face of the hook base 1 form a clamping opening for clamping the wall of the hook mounting groove, and the opening direction of the clamping opening is vertically downward.
[0034] During implementation, the spring piece 3 abuts against the top of the adjustment panel 10, allowing the limiting protrusion to lock onto the limiting protrusion 11. The top of the spring piece is then pressed down and locked by sliding the cover. At this time, the locking edge and the rear end face of the hook seat form a clamping opening. This clamping opening is clamped onto the groove wall of the hook mounting slot. The hook located on the front side of the hook seat can effectively provide fixation, facilitating subsequent support and fixation of the end of the curtain rod.
[0035] During adjustment, the limiting protrusion is an inclined protrusion. By pressing the locking edge towards the hook seat, the clamping opening is reduced, thus achieving a clamping effect. The correct method is to pull the spring piece outwards to the maximum position of the clamping opening, align the clamping opening with the wall of the hook mounting groove, and then press the locking edge to achieve clamping. During the pressing process, the inclined limiting protrusion spring piece ensures that the clamped surface remains pressed down.
[0036] Preferably, the top left and right sides of the hook seat 1 are provided with side sliding grooves 12, the left and right ends of the pressure cover 4 extend downward and form sliding joints 40 that cooperate with the side sliding grooves 12, and the bottom of the pressure cover 4 is provided with a cover plate 41 for covering the spring piece 3.
[0037] During implementation, since there is a certain gap between the pressure cap and the adjustment panel, a cover plate 41 is added to further enhance the compression of the spring sheet.

The limiting blocks 13 are located on the rear side of the adjustment panel 10 in the vertical direction, and the front end face of the limiting block 13 forms a longitudinal gap with the rear end face of the adjustment panel 10.
[0039] In the above structure, the lateral and longitudinal gaps facilitate the insertion of the spring clips, and the limiting block restricts the pressure cap from moving backward and disengaging, ensuring the sliding range.
[0040] Preferably, the spring piece 3 has a U-shaped groove 32 located on one side of the limiting protrusion 31 in the middle. The upper surface of the spring piece 3 forms a horizontally arranged spring tongue 33 through the U-shaped groove 32. During the compression process, it can deform, so that the spring piece can be effectively fixed between the pressure cover and the adjustment panel.
[0041] Preferably, the angle formed by the spring piece 3 and the locking edge 30 is an acute angle, which improves the locking capability.
[0042] Preferably, the bottom of the locking edge 30 is provided with an outwardly extending curved edge 34, and the bottom of the curved edge 34 is provided with an arc-shaped notch 35. The curved edge provided at the end can be easily slid in for installation, and the notch formed can further reduce installation resistance.
[0043] Preferably, a baffle 42 is provided between the front ends of the two sliding parts 40, which can effectively prevent the sliding parts from moving forward, avoid the pressure cover from sliding forward out of the side groove, and improve the service life.
[0044] Preferably, the front side of the hook seat 1 is provided with a snap-fit hole 14, and a plurality of snap-fit grooves 15 are provided on the outer side of the snap-fit hole 14. The hook 2 includes a hook plate 20 that abuts against the front side of the hook seat 1. A fixing hook 21 is provided on the front side of the hook plate 20.
