Description

Technical Field

[0001] This utility model relates to the installation and fixing of curtain tracks, and in particular to a quick-installation curtain track fixing structure. Background Technology

[0002] Generally, when installing curtains, a track fixing structure is first installed on the wall or window frame, and then the curtains are installed on the track fixing structure. The disadvantage of this installation method is that the wall or window frame must be fixed in a destructive way when installing the track fixing structure. For example, holes must be drilled in the wall or window frame with nails, bolts, or drilled before the nails or bolts can be fixed to the wall.

[0003] Therefore, existing technologies have proposed methods for installing curtain tracks without drilling. For example, Chinese Patent Publication No. CN218234690U discloses "An External Drill-Free Installation Mechanism for Curtains," Chinese Patent Publication No. CN220599677U discloses "A Drill-Free Mounting Frame," and US Patent Publication No. 10597938 discloses "CURTAINMOUNTING UNIT." These cases disclose the use of two screws or a screw and bolt combination to achieve the purpose of drilling-free installation of curtain tracks. However, these previous cases all share a common problem: they are not easy to operate and take a long time to complete.

[0004] Taking the structure of the previous case with Chinese patent announcement number CN218234690U as an example, since the driving component needs to rotate many times before the worm gear part of the linkage part rotates once, and the worm gear part rotates once before the screw part can also rotate once, so that the locking block can move forward or backward a little bit. This operation method is very inefficient and the effect is not ideal. Utility Model Content

[0023] Please see the appendix Figures 1 to 5 As shown, this embodiment provides a quick-installation curtain track fixing structure, including a housing 10, which is formed by two shell parts 11 fitted together, and is used to be installed at both ends of a general curtain track. One end of the housing 10 has an opening 12, and one side of the housing 10 has a through hole 13, at which a swivel bearing portion 14 is provided. Inside the housing 10, there is a circular support portion 15 and a sliding groove 16. The support portion 15 is composed of two baffles 17 with semi-circular recesses on the two shell parts. The support portion 15 is located on one side of the sliding groove 16, and the sliding groove 16 communicates with the opening 12. Each of the opposite side surfaces of the housing has a guide groove 18, and both guide grooves 18 are arranged along the long axis of the sliding groove 16.

[0024] A rotating shaft 20 is located at the bearing portion 14 of the through hole 13. One end of the rotating shaft 20 has an inner polygonal hole 21, which is exposed at the through hole 13 of the housing. The other end of the rotating shaft 20 is provided with a drive bevel gear 22. In this embodiment, the inner polygonal hole 21 is a hexagonal hole, but it is not limited thereto; it can also be a triangular hole, a square hole, a slotted hole, or a cross hole.

[0025] A lead screw 30 is disposed within the housing 10. The lead screw 30 has a screw portion 31, an annular groove 32, a driven bevel gear 33, and a receiving hole 34. The driven bevel gear 33 is disposed at one end of the lead screw 30, and the receiving hole 34 is provided at the other end of the lead screw 30. The receiving hole 34 is disposed along the long axis of the lead screw 30, and a spring 35 is disposed within the receiving hole 34. The driven bevel gear 33 meshes with the driving bevel gear 22 of the rotating shaft, thereby driving the rotating shaft 20 to rotate and thus driving the lead screw 30 to rotate. The annular groove 32 is disposed between the screw portion 31 and the driven bevel gear 33, and the annular groove 32 spans the support portion 15 of the housing, so that the lead screw 30 can rotate within the housing 10 without moving, while the screw portion 31 is located within the sliding groove 16.

[0026] A slider 40 is disposed in a groove 16 of the housing and moves within the groove. One end of the slider 40 has a rear abutment surface 41 with a through hole 42 at its center, into which one end of a screw is inserted. The other end of the slider 40 has a front abutment surface 43. A guide block 44 is provided on each side of the slider 40, and the two guide blocks 44 are respectively disposed in guide grooves 18 on the two sides of the housing 10, thereby playing a guiding role. One end of a spring 35 presses against the other side of the front abutment surface 43, and the other end of the spring 35 presses against the receiving hole 34, thereby supporting the slider 40 through the spring 35.

[0027] A stop block 50 is provided with a threaded hole 51 in the middle of the stop block. The stop block 50 is sleeved on the guide screw 30 and is screwed into the screw part 31 of the guide screw through the threaded hole 51. The rotation of the guide screw 30 can move the stop block 50 and press against the rear abutment surface of the slider, thereby pushing the slider to move.

[0028] With the above-described structure, the quick-installation curtain track fixing structure of the present invention is used in the same way as traditional products, installed at both ends of a general curtain track. Under normal conditions, the slider 40 will be held in the position protruding from the opening 12 of the housing due to the elastic force of the spring 35. Figure 4 and Figure 1 As shown.

[0029] During installation, the user can first press the front abutment 43 of the slider 40 against one side of the window frame to retract the slider 40, causing the spring 35 to be compressed. Then, align the other end of the curtain track with the other side of the window frame. Using the spring's elastic restoring force, release the pressure to allow the slider 40 to pop out, so that the front abutment 43 of the slider can press against the window frame. It is important to emphasize that the elasticity of the spring 35 must be sufficient to support the weight of the curtain, so that the curtain track can be temporarily pressed and fixed to the window frame.

[0030] Then, by rotating the inner polygonal hole with a tool, the rotating shaft 20 is rotated. The rotating shaft 20 will drive the guide screw 30 to rotate, thereby moving the abutment block 50. When the abutment block 50 moves to press against the rear abutment surface 41 of the slider 40, the position of the slider 40 can be fixed and cannot be moved. In this way, the curtain track can be pressed against both sides of the window frame without drilling holes, thus completing the installation and fixing of the curtain track.

[0031] It should be noted that, in this application, the number of teeth of the driving bevel gear 22 on the rotating shaft 20 is more than 0.7 times the number of teeth of the driven bevel gear 33 on the guide screw 30, preferably between 0.7 and 1.5 times. That is, if the number of teeth of the driven bevel gear 33 on the guide screw is 10, then the number of teeth of the driving bevel gear 22 on the rotating shaft is 7 to 15. This is necessary to achieve rapid movement of the abutment to achieve the purpose of the present invention and improve installation efficiency.

[0032] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
