Description

Technical Field

[0001] The present invention relates to a curtain track installation and fixing device, in particular to a curtain track fixing structure that can be installed quickly. Prior Art

[0002] Typically, when installing curtains, a track-mounted structure is first installed on the wall or window frame, and then the curtains are mounted on the track-mounted structure. However, this installation method requires destructive fixing of the wall or window frame. For example, holes must be drilled or drilled in the wall or window frame before the nails or bolts can be fixed to the wall.

[0003] Therefore, some have proposed methods for drilling-free curtain track installation, such as Mainland China Publication No. 218234690U, "A Drill-Free Installation Mechanism for Curtains," Mainland China Publication No. 220599677, "A Drill-Free Mounting Rack," and U.S. Publication No. 10597938, "CURTAIN MOUNTING UNIT." These cases disclose the use of two screws or a screw plus a bolt to achieve drilling-free installation of curtain tracks. However, these previous cases share the common problem of being difficult and time-consuming to install.

[0004] Take the structure of the previous patent application, Publication No. 218234690U, from mainland China, for example. The drive element requires multiple rotations for the worm gear in the linkage to complete one rotation, and each rotation of the worm gear also requires one rotation of the screw, which in turn moves the locking block even slightly forward or backward. This operating method is inefficient and unsatisfactory. Summary of the Invention

[0005] The main purpose of the present invention is to provide a curtain track fixing structure that is quick and easy to operate and can be quickly installed.

[0006] To achieve the aforementioned primary objectives, the present invention provides a quickly installable curtain rail fixing structure comprising: a housing having a slide groove therein and a through hole formed on one side of the housing; a rotating shaft disposed within the through hole, one end of the rotating shaft having an inner polygonal hole exposed through the through hole of the housing; and a driving bevel gear disposed at the other end of the rotating shaft; a lead screw disposed within the housing, the lead screw having a screw portion, a driven bevel gear, and a receiving hole; the driven bevel gear disposed at one end of the lead screw and meshing with the driving bevel gear of the rotating shaft, the screw portion resting within the slide groove; the receiving hole being axially oriented along the lead screw, and a spring disposed within the receiving hole; and a slider disposed within the slide groove of the housing and capable of movement therein, one end of the slider having a rear abutment surface and the other end of the slider having a front abutment surface, one end of the spring abutting against the other side of the front abutment surface. A stop block is provided with a threaded hole. The stop block is sleeved on the lead screw and is screwed with the screw portion of the lead screw through the threaded hole. The rotation of the lead screw can move the stop block.

[0007] Due to the above-described structure, the rotation of the rotating shaft in the present invention can drive the lead screw to rotate, causing the block to move and abut against the rear abutment surface of the slider. The number of teeth on the active bevel gear on the rotating shaft is 0.7 to 1.5 times the number of teeth on the passive bevel gear on the lead screw. Therefore, the rotating shaft can directly, clearly, and efficiently drive the lead screw to rotate and move the slider, thereby improving installation efficiency. Simple diagram description

[0009] The applicant first explains that throughout this specification, including the embodiments described below and the claims in the patent application, directional terms are based on the directions in the drawings. Furthermore, in the embodiments and drawings described below, identical component numbers represent identical or similar components or structural features. Directions in this specification are based on the directions in the drawings for ease of description and are not intended to be limiting.

[0010] Please refer to Figures 1 to 5, which show the curtain track fixing structure that can be quickly installed according to the present invention, including:

[0011] A housing 10, comprised of two shell members 11, is designed to be mounted on either end of a typical curtain track. An opening 12 is defined at one end of the housing 10, and a through-hole 13 is provided on one side of the housing. A swivel bearing 14 is located within the through-hole 13. A circular support 15 and a chute 16 are located within the housing 10. The support 15 is formed by two baffles 17 with semicircular recesses formed on the two shell members. The support 15 is located on one side of the chute 16, which communicates with the opening 12. Two guide grooves 18 are provided on opposite sides of the housing, each extending along the longitudinal axis of the chute 16.

[0012] A rotating shaft 20 is mounted on the rotating 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. A driving bevel gear 22 is mounted on the other end of the rotating shaft 20. In this embodiment, the inner polygonal hole is a hexagonal hole, but this is not limited to a hexagonal hole. Alternatively, it may be a triangular hole, a square hole, a straight hole, or a cross hole.

[0013] A lead screw 30 is disposed in the housing 10. The lead screw 30 has a screw portion 31, an annular groove 32, a passive bevel gear 33 and a receiving hole 34. The passive bevel gear 33 is disposed at one end of the lead screw 30, and the receiving hole 34 is disposed 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 in the receiving hole 34. The passive bevel gear 33 engages with the active bevel gear 22 of the rotating shaft. The annular groove 32 is disposed between the screw portion 31 and the passive bevel gear 33. The annular groove 32 is spanned across the supporting portion 15 of the housing so that the lead screw 30 can rotate in the housing 10 without moving, and the screw portion 31 falls into the slide groove 16.

[0014] A slider 40 is mounted in the housing's slide slot 16 and moves within the slot. One end of the slider 40 is provided with a rear abutment surface 41 with a through-hole 42, and the other end of the slider 40 is provided with a front abutment surface 43. A guide block 44 is positioned on each side of the slider 40, corresponding to the guide slot 18 provided on two side surfaces of the housing 10. One end of the spring 35 abuts against the other side of the front abutment surface 43, while the other end of the spring 35 abuts within the receiving hole 34.

[0015] A stop block 50 is provided with a threaded hole 51. The stop block 50 is sleeved on the lead screw 30 and is screwed with the screw portion 31 of the lead screw through the threaded hole 51. The rotation of the lead screw 30 can move the stop block 50.

[0016] With the above-described structure, the quick-install curtain track fixing structure of the present invention is installed at both ends of a conventional curtain track in the same manner as conventional products. Under normal conditions, the slider 40 is maintained in a position protruding from the opening 12 due to the elastic force of the spring 35, as shown in Figures 4 and 1.

[0017] During installation, the user first presses the front abutment surface 43 of the slider 40 against one side of the window frame to retract the slider 40, compressing the spring 35. Then, align the other end of the curtain track with the other side of the window frame. Using the spring's elastic restorative force, the user releases the pressure, causing the slider 40 to pop out and allow the front abutment surface 43 to rest against the window frame. It's important to note that the spring 35's elastic force must be sufficient to support the weight of the curtain, allowing the curtain track to temporarily rest against the window frame.

[0018] Then, by rotating the inner polygonal hole, the rotating shaft 20 is rotated, and the rotating shaft 20 drives the lead screw 30 to move the block 50. When the block 50 moves to abut against the rear abutting 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 abutted against both sides of the window frame without drilling holes, completing the installation and fixation of the curtain track.

[0019] It should be particularly noted that in the present invention, the number of teeth on the active bevel gear 22 on the rotating shaft 20 is at least 0.7 times the number of teeth on the passive bevel gear 33 on the lead screw 30, and preferably is between 0.7 and 1.5 times. That is, if the number of teeth on the passive bevel gear 33 on the lead screw is 10, the number of teeth on the active bevel gear 22 on the rotating shaft is 7 to 15. This is the only way to quickly move the stop block and achieve the purpose of the present invention, thereby improving installation efficiency.
