Technical Field

[0001] The present invention relates to the technical field of curtain installation, and particularly relates to a hole-free installation component for installing curtains. Background Art

[0002] Curtains are widely used in places such as homes and offices, mainly for adjusting indoor light. Currently, roller blinds, venetian blinds, honeycomb blinds, etc. are commonly used. Generally, when installing, the curtain needs to be fixed to the window frame through mounting codes and screws. Since screw installation will create screw holes on the window frame, when reinstalling or replacing the curtain, it is necessary to drill new holes and cannot be installed in place. Inevitably, multiple screw holes will be left on the wall of the window frame, which not only damages the wall but also affects the aesthetics. Moreover, drilling for installation will generate dust, making cleaning inconvenient, and the installation is time-consuming and laborious. Summary of the Invention

[0003] Aiming at the current situation of the above-mentioned existing technology, the technical problem to be solved by the present invention is to provide a hole-free installation component for installing curtains, which can quickly install the curtain without drilling and damaging the wall, and is convenient for installation.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a hole-free installation component for installing curtains, including a mounting seat. A top block slidably connected to the mounting seat is provided inside the mounting seat, and a self-locking unit for pushing the top block is provided. A part of the structure of the self-locking unit is exposed outside the mounting seat.

[0005] Further, one end of the mounting seat is a closed end, and the other end is an open end. The self-locking unit includes a worm gear, a worm, a lead screw, and a lead screw nut. The worm gear is integrally formed with the lead screw. The worm is in threaded cooperation with the worm gear. The lead screw nut is screwed onto the lead screw. A through hole for the lead screw to extend into is opened at the closed end of the mounting seat, and both the worm gear and the worm are exposed outside the mounting seat.

[0006] Further, the shape of the top block matches the shape of the inner cavity of the mounting seat. A circular cavity for sleeving the lead screw and the lead screw nut is inwardly opened on the top block. A square end surface that matches the shape of the inner cavity of the mounting seat and is used for pushing the top block is provided on the lead screw nut.

[0007] Further, an elastic member is also provided inside the mounting seat. One end of the elastic member is sleeved on the lead screw nut and abuts against the square end surface of the lead screw nut, and the other end extends into the circular cavity and abuts against the inner end surface of the top block.

[0008] Further, a top cover is connected to the outer end surface of the top block.

[0009] Further, guide blocks are symmetrically arranged on two outer side walls of the top block, guide grooves cooperating with the guide blocks are arranged on two inner side walls of the mounting base, anti-slip blocks for preventing the guide blocks from slipping off are arranged at ends of the guide grooves, and the anti-slip blocks are flush with an open end of the mounting base.

[0010] Further, a connection cover is mounted at a closed end of the mounting base, a first arc-shaped groove is arranged on the connection cover, a second arc-shaped groove opposite to the first arc-shaped groove is arranged on the mounting base, and the first arc-shaped groove and the second arc-shaped groove form a receiving cavity for accommodating a worm.

[0011] Further, a concave cavity for avoiding a worm gear is concaved on the connection cover, and the concave cavity communicates with the receiving cavity.

[0012] Further, both ends of the receiving cavity communicate with the outside, first annular step surfaces are symmetrically arranged in the receiving cavity, and second annular step surfaces cooperating with the first annular step surfaces are arranged on the worm.

Detailed implementation mode

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and the detailed implementation mode.

[0022] As Figures 1-4 shown, a punch - free installation component for installing curtains includes a mounting base 1. A top block 3 slidably connected to the mounting base 1 is provided inside the mounting base 1, and a self - locking unit for pushing the top block 3 is provided. A part of the structure of the self - locking unit is exposed outside the mounting base 1.

[0023] One end of the mounting base 1 is a closed end and the other end is an open end. The self-locking unit includes a worm gear 5, a worm 4, a lead screw 6 and a lead screw nut 7. The worm gear 5 is integrally formed with the lead screw 6. The worm 4 is in threaded engagement with the worm gear 5. The lead screw nut 7 is screwed onto the lead screw 6. A through hole 1.1 for the lead screw 6 to extend into is formed in the closed end of the mounting base 1. Both the worm gear 5 and the worm 4 are exposed outside the mounting base 1. The shape of the top block 3 matches the shape of the inner cavity of the mounting base 1. A circular cavity 3.1 for sleeving the lead screw 6 and the lead screw nut 7 is formed inwardly on the top block 3. A square end face 7.1 which matches the shape of the inner cavity of the mounting base 1 and is used to push the top block 3 is provided on the lead screw nut 7. By rotating the worm 4 through an external driving component, the worm 4 drives the worm gear 5 to rotate. The worm gear 5 drives the lead screw 6 to rotate synchronously. The lead screw 6 drives the lead screw nut 7 to move along the length direction of the lead screw 6. The square end face 7.1 on the lead screw nut 7 pushes the top block 3 until the top block 3 is locked, and the top block 3 is tightly pressed against the wall surface. The cooperation of the worm gear 5, the worm 4 and the lead screw 6 converts the axial rotation into the radial rotation, and the mechanical force of the self-locking unit is used to lock the top block 3, which is convenient for installation and adjustment. Further, an elastic member 2 is further provided in the mounting base 1. One end of the elastic member 2 is sleeved with the lead screw nut 7 and abuts against the square end face 7.1 of the lead screw nut 7, and the other end extends into the circular cavity 3.1 and abuts against the inner end face of the top block 3. The setting of the elastic member 2 will apply an elastic force to the top block 3 during pre-installation, so that the top block 3 abuts against the wall surface to complete pre-positioning. When the external driving component rotates the worm 4, the worm 4 drives the worm gear 5 to rotate. The worm gear 5 drives the lead screw 6 to rotate synchronously. The lead screw 6 drives the lead screw nut 7 to move along the length direction of the lead screw 6. First, the square end face 7.1 of the lead screw nut 7 pushes the elastic member 2, and the elastic member 2 pushes the top block 3. As the elastic member 2 is squeezed, the elastic force received by the top block 3 becomes larger and larger until the elastic member 2 is completely pushed into the circular cavity 3.1, and the square end face 7.1 of the lead screw nut 7 abuts tightly against the top block 3, and the top block 3 is completely locked. And during the pre-installation process of the elastic member 2, an elastic force is applied to the top block 3 so that the top block 3 can abut against the wall surface to realize pre-positioning, making the installation and positioning more convenient and accurate. Preferably, the elastic member 2 is a spring or a group of mutually repulsive magnets. Guide blocks 3.2 are symmetrically provided on the two outer side walls of the top block 3. Guide grooves 1.2 which cooperate with the guide blocks 3.2 are provided on the two inner side walls of the mounting base 1. Anti-slip blocks 1.3 for preventing the guide blocks 3.2 from slipping off are provided at the ends of the guide grooves 1.2. The anti-slip blocks 1.3 are flush with the open end of the mounting base 1. An inclined guide surface is provided on the guide block 3.2. During the process of assembling the top block 3 into the mounting base 1, it can be smoothly pushed into the mounting base 1 along the inclined guide surface. Moreover, when the top block 3 slides reversely under the elastic force of the elastic member 2, the anti-slip blocks 1.3 block the guide blocks 3.2 from sliding out of the guide grooves 1.2, preventing the top block 3 from detaching from the mounting base 1. One end of the top block 3 extends out of the mounting base 1 to be used for abutting against the wall surface to realize installation, and the other end of the top block 3 always slides within the range of the inner cavity of the mounting base 1. Guide block 3.The sliding distance of the slider 3 within the guide groove 1.2 is the telescopic displacement of the ejector block 3.

[0024] Preferably, a top cover 8 is connected to the outer end surface of the ejector block 3, which can increase the friction force with the wall surface, prevent slipping, enable it to lean against the wall surface more stably, have better contact with the wall surface, and also play a role in aesthetics.

[0025] A connection cover 9 is installed at the closed end of the mounting seat 1. The connection cover 9 is provided with a first arc-shaped groove 9.1. The mounting seat 1 is provided with a second arc-shaped groove 1.4 opposite to the first arc-shaped groove 9.1. The first arc-shaped groove 9.1 and the second arc-shaped groove 1.4 form a receiving cavity 10 for accommodating the worm 4. The receiving cavity 10 is vertically distributed with respect to the inner cavity of the mounting seat 1. The structure of splicing the first arc-shaped groove 9.1 and the second arc-shaped groove 1.4 is adopted to accommodate the worm 4, making it convenient to disassemble, assemble, and replace parts. A concave cavity 9.2 for avoiding the worm gear 5 is recessed in the connection cover 9. The concave cavity 9.2 communicates with the receiving cavity 10. Both ends of the receiving cavity 10 communicate with the outside, facilitating the external driving component to extend into the receiving cavity 10 to screw the worm 4, thereby achieving the purpose of self-locking. First annular step surfaces 10.1 are symmetrically arranged in the receiving cavity 10. The worm 4 is provided with second annular step surfaces 4.1 that cooperate with the first annular step surfaces 10.1. The first annular step surfaces 10.1 and the second annular step surfaces 4.1 cooperate with each other to prevent the worm 4 from falling out of the receiving cavity 10 during rotation, avoid displacement of the worm 4 along its own length direction, thereby protecting the worm gear 5 and the worm 4 and preventing the worm gear 5 and the worm 4 from being damaged.

[0026] In addition, a connection portion 9.3 for connecting the curtain mounting rod extends from the end of the connection cover 9 away from the mounting seat 1, facilitating assembly with the curtain mounting rod.

[0027] During use, such as Figure 5As shown, the non-drilling installation component can be directly inserted into the curtain installation rod, and then connected to the curtain body through the connectors at both ends. Then, the curtain is pre-positioned on the window frame. At this time, the top block 3 is pressed against the wall under the elastic force of the elastic member 2 to achieve pre-positioning. The driving member extends into the accommodating cavity 10 to rotate the worm 4. The worm 4 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the lead screw 6 to rotate synchronously. Since the square end face 7.1 of the lead screw nut 7 on the lead screw 6 matches the shape of the inner cavity of the mounting seat 1, the lead screw nut 7 is limited and cannot rotate synchronously with the lead screw 6. Therefore, the rotation of the lead screw 6 will push the lead screw nut 7 to move along the length direction of the lead screw 6. The square end face 7.1 of the lead screw nut 7 pushes the elastic member 2 towards the top block 3 until the elastic member 2 is completely pushed into the circular cavity 3.1. The square end face 7.1 of the lead screw nut 7 abuts against the top block 3, thereby locking the top block 3 and preventing the top block 3 from sliding reversely, so as to support the curtain on the window frame and achieve non-drilling installation without damaging the wall. When the curtain needs to be replaced or disassembled, the driving member extends into the accommodating cavity 10 to rotate the worm 4 reversely. The worm 4 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the lead screw 6 to rotate synchronously. The lead screw nut 7 on the lead screw 6 moves away from the top block 3, the elastic member 2 is released, the elastic force decreases, and the top block 3 is unlocked. The top block 3 can be squeezed to move into the mounting seat 1, so that the top block 3 is separated from the wall, and the curtain can be easily removed. In addition, since the worm wheel 5 and the worm 4 are arranged away from the top block 3, when the driving member is used to rotate the worm 4, the worm 4 is away from the wall, and the driving member will not hit the wall when rotating, which is more convenient for the driving member to rotate and will not cause awkward operation due to being close to the wall.
