Description

Technical Field

[0001] This utility model belongs to the field of curtains, specifically relating to a hole-free installation end cap. Background Technology

[0002] No-drill curtains are popular because they can be installed on window frames without drilling holes or nails. Currently available no-drill curtains typically have a tightening mechanism on the left or right end of the track, accompanied by an installation wrench. During installation, the tightening mechanism is positioned with the window frame above and the curtain fabric below, resulting in limited space and inconvenience. Some no-drill curtain devices lack a pre-tensioning spring, requiring the curtain to be held up with one hand while the device is tightened with the other until secure. This is difficult to achieve with larger or heavier curtains. Patent CN215348288U discloses a simple and quick curtain installation mechanism that uses a screw to move a push block vertically inward, thereby pushing an adjusting rod connected to the push block via an inclined plane to extend outward along the length of the curtain. However, this structure also has the following drawbacks: the screw connects to a stop post, extending too far out of the curtain, taking up too much space and affecting the curtain's aesthetics and safety. Furthermore, the push block can only move inward and outward, not left and right, and the displacement of the adjusting rod via the inclined plane is limited and the pushing speed is slow. Summary of the Invention

[0003] This utility model provides a hole-free installation end cap.

[0004] The purpose of this utility model is achieved in the following manner: a punch-free mounting end cap includes a housing and a support mechanism with one end slidably disposed inside the housing along the length of the housing and the other end extending out of the housing; a screw that can slide along the length of the housing is disposed inside the housing, and a pressure block serving as a nut is disposed on the screw; a cover is fixedly disposed inside the housing on the side away from the support mechanism; the rotation of the screw drives the pressure block to move inward or outward, and the cover and the pressure block, through inclined surface cooperation, push the screw and the pressure block together to slide left and right along the length of the housing; the left and right movement of the pressure block presses or releases the support mechanism.

[0005] A clamping block is provided on the side of the pressure block away from the cover, and the clamping block is slidably disposed inside the outer shell; the pressure block and the clamping block are engaged by inclined surfaces, and the inclined surface of the pressure block near the cover is in the opposite direction to the inclined surface of the clamping block.

[0006] A spring is provided between the clamping block and the support mechanism on the side closest to the support mechanism.

[0007] The support mechanism includes a support block that is slidably disposed within the housing at one end; a spring is disposed between the support block and the clamping block; a support seat is fixedly disposed at the other end of the support block; and an elastic pad is disposed at the end of the support seat away from the spring.

[0008] The screw is a double-ended screw, with a pressure block threaded to each end of the double-ended screw, and the two pressure blocks are symmetrically arranged; the cover includes two symmetrically arranged inclined surfaces that cooperate with one side of the two pressure blocks respectively; the clamping block also includes two symmetrically arranged inclined surfaces that cooperate with the other side of the two pressure blocks respectively; sliding grooves are respectively provided on the outer shell corresponding to the two ends of the double-ended screw.

[0009] The two ends of the double-ended screw are respectively threaded to a left-hand nut and a right-hand nut; one of the two pressure blocks is provided with a groove corresponding to the left-hand nut that mates with it, and the other is provided with a groove corresponding to the right-hand nut that mates with it.

[0010] The pressure block also has an inclined surface on the side near the support mechanism, and the inclined surface contacts the end of the support mechanism located inside the outer shell; the inclined surface of the pressure block near the cover has the opposite inclination direction to the inclined surface near the support mechanism.

[0011] Compared to existing technologies, in this invention, the screw rotation drives the pressure block to move inward and outward and slide left and right, thereby achieving the pressing or releasing of the support mechanism in the left and right directions. The pressure block has inclined contact surfaces on both sides, allowing for faster pressing or releasing of the support mechanism. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-5As shown, a drill-free mounting cap includes a housing 11 and a support mechanism with one end slidably disposed inside the housing 11 along its length and the other end extending out of the housing 11. A screw capable of sliding along the length of the housing 11 is disposed inside the housing 11, and a pressure block 2 serving as a nut is disposed on the screw. A cap 1 is fixedly disposed on the side of the housing 11 away from the support mechanism. Rotation of the screw drives the pressure block 2 to move inward or outward. The cap 1 and the pressure block 2, through inclined surface cooperation, push the screw and the pressure block 2 together to slide left and right along the length of the housing 11. The left and right movement of the pressure block 2 presses or releases the support mechanism. Preferably, the axis of the screw is perpendicular to the length of the housing 11, although a certain tilt angle can also achieve the function. The direction of the screw's sliding is parallel to the length of the housing 11 or allows for a certain tilt angle. Here, left and right refer to the length direction of the housing 11; inside and outside refer to the width or height direction. A limiting mechanism is provided between one end of the support mechanism and the outer shell 11 to prevent one end of the support mechanism from detaching from the outer shell 11. The cover 1 can be fixed to the outer shell 11 by fixing screws 10. The outer shell 11 is hollow inside and has openings at both ends. The pressure block 2 moves left and right to press the support mechanism against the wall or window frame 16, or to release the support mechanism. Schemes where the pressure block 2 directly contacts the end of the support mechanism located inside the outer shell 11, or indirectly contacts it through other structures, are all within the protection scope of this utility model. In this utility model, when the screw rotates, it can drive the pressure block 2 to move inward and outward and slide left and right, thereby achieving the pressing or releasing of the support mechanism in the left and right directions.

[0020] Furthermore, a clamping block 7 is provided on the side of the pressure block 2 away from the cover 1, and the clamping block 7 is slidably disposed within the outer casing 11; the pressure block 2 and the clamping block 7 are engaged by an inclined plane, and the inclined plane of the pressure block 2 near the cover 1 has an opposite inclination direction to the inclined plane near the clamping plane. A sliding clamping block 7 is provided between the pressure block 2 and the support mechanism, thereby clamping and releasing the support mechanism. When the curtain needs to be fixed, the screw rotates, the pressure block 2 moves inward, and the inclined plane engages with the clamping block 7 to move to the right. Simultaneously, the inclined plane of the pressure block 2 engages with the cover 1, pushing the pressure block 2 and the screw as a whole to move to the right. Compared to the method where only the pressure block 2 and the support mechanism are engaged by an inclined plane, the clamping block 7 moves to the right faster in this invention, achieving the clamping of the support mechanism more quickly. Of course, the clamping block 7 can also be omitted, and the pressure block 2 directly engages with the inclined plane of the support mechanism.

[0021] Furthermore, a spring 8 is provided between the clamping block 7 and the support mechanism on the side closest to the support mechanism. The spring 8 ensures that the clamping block 7, the pressure block 2, and the cover 1 press against each other, guaranteeing that the screw remains perpendicular to the outer casing 11 during movement. (Without the spring 8, manual reset may be required.) Specifically, the support mechanism includes a support block 9 slidably disposed within the outer casing 11 at one end; a spring 8 is disposed between the support block 9 and the clamping block 7; a support base 12 is fixedly disposed at the other end of the support block 9; and an elastic pad is disposed at the end of the support base 12 away from the spring 8. This elastic pad can be a silicone pad 14, which contacts the wall or window frame 16 to provide cushioning. The support base 12 and the support block 9 can be connected by fixing screws 10. Two parallel springs 8 can be disposed between the support block 9 and the clamping block 7 to achieve symmetrical clamping. A stepped hole can be provided at the end of the outer casing 11 near the support block 9 to secure one end of the support block 9 and prevent it from detaching.

[0022] Preferably, the screw is a double-ended screw 4, with each end of the double-ended screw 4 threadedly connected to a pressure block 2, and the two pressure blocks 2 are symmetrically arranged. The cover 1 includes two symmetrically arranged inclined surfaces that respectively cooperate with one side of the two pressure blocks 2. The clamping block 7 also includes two symmetrically arranged inclined surfaces that respectively cooperate with the other side of the two pressure blocks 2. The outer shell 11 is provided with sliding grooves 5 corresponding to the two ends of the double-ended screw 4. Specifically, the shape of the pressure block 2 can be an isosceles trapezoid, with the short side facing inward and the long side facing outward. The shape of the cover 1 and the side of the clamping block 7 facing the pressure block 2 can be a triangle or an isosceles trapezoid, with the short side facing inward and the long side away from the pressure block 2.

[0023] Specifically, the two ends of the double-ended screw 4 are respectively threaded to a left-hand nut 3 and a right-hand nut; one of the two pressure blocks 2 has a groove corresponding to the left-hand nut it mates with, and the other has a groove corresponding to the right-hand nut it mates with. The installation positions of the left-hand and right-hand nuts are determined by the threads of the double-ended screw 4, which is existing technology. The left-hand nut 3 and right-hand nut 6 are respectively embedded in the grooves of the corresponding pressure blocks 2, thereby fixing the pressure blocks 2 to the double-ended screw 4; other connection methods are also within the protection scope of this utility model. The function of this utility model can also be achieved by directly threading the pressure blocks 2 to the corresponding ends of the double-ended screw 4 without the left-hand nut 3 and right-hand nut 6.

[0024] In another embodiment, the pressure block 2 also has a slope on the side near the support mechanism, and the slope engages with the end of the support mechanism located inside the outer casing 11; the slope of the pressure block 2 near the cover 1 is in the opposite direction to the slope of the slope near the support mechanism. In this embodiment, the clamping block 7 is not provided. The two sides of the pressure block 2 engage with the cover 1 and the support mechanism respectively through slopes, enabling rapid left and right movement of the support mechanism.

[0025] In practice: One end of the double-ended screw 4 has a left-hand thread, and the other end has a right-hand thread. A wrench is inserted into the hexagonal holes at both ends of the double-ended screw, and the double-ended screw 4 is rotated clockwise. The two pressure blocks 2 move inward and tighten, and the clamping block 7 is pushed forward along the inclined surface by the pressure blocks 2 until it fits tightly against the support block 9, so that the support seat 12 and the silicone pad 14 are pressed against the window frame 16. The other end of the pressure block 2 abuts against the cover 1, which is fixedly connected to the outer shell 11. The outer shell 11 is fixed to the track 15, and the outer shell 11 tightens the curtain track 15, thus fixing the curtain to the window frame 16. A groove is also provided on the track 15 corresponding to the double-ended screw 4. Rotating the double-ended screw 4 counterclockwise moves the two pressure blocks 2 outward, separating the clamping block 7 from the support block 9, allowing the curtain to be removed from the window frame 16.

[0026] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
