[0029] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "upper", "lower" and the like is based on the orientation or position relationship when the product is normally used.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] This utility model embodiment one provides a drilling-free mounting component, combined with... Figures 1-7 As shown, the device includes a housing, a rotating base 2, and a body 3. The rotating base 2 is partially housed within the housing and rotatably connected to it. The rotating base 2 has an axially penetrating cavity 21. The body 3 is slidably inserted into the cavity 21. A limiting member 4 is slidably fitted onto the body 3. The outer wall of the limiting member 4 is threadedly connected to the inner wall of the cavity 21. The body 3 has a radially protruding first limiting part 31, which is slidably connected to the cavity 21 and abuts against one end of the limiting member 4. When the rotating base 2 is rotated, the limiting member 4 moves axially along the cavity 21 until it presses against the first limiting part 31, thereby restricting the axial movement of the body 3.

[0032] Optionally, the outer shell is a first outer shell 1-1, which is rotatably connected to the body 3 to be suitable for installation on a roller blind; or the outer shell is a second outer shell 1-2, which has a second limiting block 12 protruding inside and a second limiting groove 37 recessed on the body 3. The second limiting block 12 is limited in the second limiting groove 37 and is axially slidably connected to the second limiting groove 37 so that the second outer shell 1-2 and the body 3 do not rotate to be suitable for installation on a pleated blind.

[0033] Example 1:

[0034] like Figure 7 As shown, curtains come in many types, with roller blinds and pleated blinds as examples. Example 1 is suitable for installation on roller blinds. Roller blinds typically include a curtain rod (not shown) and a beaded cord controller 7. The two ends of the curtain rod are connected to the beaded cord controller 7 and a no-drill mounting bracket, respectively. The beaded cord controller 7 is connected to the beaded cord (not shown). When using the roller blind, the user needs to pull the beaded cord to move the blind up and down. Therefore, the beaded cord controller 7 will rotate under the user's pulling force, while the no-drill mounting bracket rotates together under the transmission action of the curtain rod.

[0035] In the first embodiment, the outer shell is the first outer shell 1-1, and the curtain rod is connected to the first outer shell 1-1, thereby driving the first outer shell 1-1 to rotate together.

[0036] like Figures 1-3As shown, the body 3, the rotating seat 2 and the first shell 1-1 are coaxially arranged, the body 3 is accommodated in the accommodating cavity 21, the rotating seat 2 is partially accommodated in the first shell 1-1, and the body 3 passes through the rotating seat 2 and the first shell 1-1 and moves back and forth along the axial direction.

[0037] The perforation-free mounting piece in the utility model is connected with one end of the curtain rod, in the installation, first, the body 3 and the other end of the curtain rod abut against the wall surface respectively, then, the rotating seat 2 is rotated, the limiting piece 4 moves axially under the action of the screw, until the first limiting part 31 is tightly pressed, the body 3 cannot move axially, thereby the position of the body 3 is locked, the installation is completed, the operation is simple and convenient, and the wall body does not need to be perforated.

[0038] Optionally, a positioning pin 11 is arranged on the first shell 1-1, an outer wall of the rotating seat 2 is annularly provided with a positioning groove 22, one end of the positioning pin 11 is limited in the positioning groove 22 and is rotationally connected with the positioning groove 22, so that the rotating seat 2 is axially positioned.

[0039] As shown in the figures, Figure 2 and 4 The positioning groove 22 is axially limited in the positioning pin 11, when the rotating seat 2 is rotated in the positive direction or the reverse direction, the rotating seat 2 does not axially displace, and the limiting piece 4 moves back and forth along the axial direction under the action of the screw. The positive direction is the clockwise direction or the counterclockwise direction, and the reverse direction is the direction opposite to the positive direction.

[0040] Optionally, the body 3 is radially provided with a second limiting part 32, the second limiting part 32 is axially slidably connected with the accommodating cavity 21, a spring 33 is sleeved on the body 3, one end of the spring 33 abuts against the second limiting part 32, and the other end of the spring 33 abuts against the inner bottom wall of the first shell 1-1 or the rotating seat 2.

[0041] As shown in the figures, Figure 2 In the first embodiment, the spring 33 is entirely accommodated in the accommodating cavity 21. When the body 3 is pressed and moves downward, the bottom end of the second limiting part 32 extrudes the spring 33, so that the spring 33 accumulates elastic force, and when the external force is released, the spring 33 pushes the second limiting part 32, thereby driving the body 3 to return to the original position.

[0042] Optionally, the limiting piece 4 is slidably sleeved on the second limiting part 32, and the second limiting part 32 is non-circular in cross section, so that the limiting piece 4 and the body 3 do not rotate relative to each other.

[0043] As shown in the figures, Figure 5 The second limiting part 32 is a regular hexagon, the limiting piece 4 is adapted to the second limiting part 32, and the limiting piece 4 and the body 3 cannot relatively rotate, so that when the rotating seat 2 is rotated, the limiting piece 4 can move axially.

[0044] Optionally, the body 3 and the first shell 1-1 are axially slidingly connected, the bottom of the body 3 is connected with a limiting sheet 34, the limiting sheet 34 is adapted to abut against the bottom of the outer wall of the first shell 1-1 to limit the moving distance of the body 3.

[0045] As shown in Figure 2 and 3 , the limiting sheet 34 is used to limit the moving distance of the body 3 upwards, when the body 3 moves upwards under the action of the spring 33, the limiting sheet 34 abuts against the bottom of the outer wall of the first shell 1-1 to prevent the body 3 from rebounding out of the top.

[0046] Optionally, the first shell 1-1 is provided with a thrust ball bearing 5, the thrust ball bearing 5 is sleeved on the body 3, and the axial two ends of the thrust ball bearing 5 abut against the bottom wall of the rotating seat 2 and the inner bottom wall of the first shell 1-1 respectively.

[0047] As shown in Figure 2 and 3 , the thrust ball bearing 5 can reduce the friction in the axial direction, so that the rotating seat 2 and the first shell 1-1 rotate more smoothly when relative rotation occurs. The lower end of the spring 33 abuts against the upper end of the thrust ball bearing 5.

[0048] Optionally, the rotating seat 2 is provided with a rotating disc part 23, and the rotating disc part 23 is provided with a plurality of protruding teeth or the cross section of the rotating disc part 23 is a regular polygon.

[0049] As shown in Figure 1 , in the first embodiment, the rotating disc part 23 is provided with a plurality of protruding teeth, and grooves are arranged on the protruding teeth at intervals, so as to facilitate the rotation of the rotating disc part 23 by means of a wrench 9 or the like, thereby driving the rotating seat 2 to rotate.

[0050] Optionally, the hole-free mounting member further comprises a connecting member 6, the connecting member 6 is connected with a rubber pad 63 for abutting against a wall body, the upper end of the body 3 is recessed with a mounting cavity 35, the bottom of the connecting member 6 is protruded with a connecting part 61, the mounting cavity 35 is recessed with a first limiting groove 36, the connecting part 61 is radially protruded with a first limiting block 62, the first limiting block 62 is limited in the first limiting groove 36 and is adapted to be movably connected with the first limiting groove 36, so as to correct the deviation and adapt to the non-perpendicular wall surface.

[0051] As shown in Figure 2 , 5As shown in Figure 6, the rubber pad 63 is used to increase the friction between the rubber pad 63 and the wall. The upper surface of the rubber pad 63 is perpendicular to the central axis of the main body 3 to adapt to vertical walls and facilitate installation. The connecting part 61 is approximately spherical, and there are four first limiting blocks 62. The four first limiting blocks 62 are evenly distributed in the front-back and left-right directions of the connecting part 61. The width of the first limiting groove 36 is slightly larger than the width of the first limiting block 62, so that the connecting part 6 can move slightly relative to the main body 3, thereby changing the angle between the upper surface of the rubber pad 63 and the central axis of the main body 3, adapting to non-vertical walls, correcting small-angle deviations of the wall, and ensuring that the curtain rod is parallel to the horizontal plane after installation.

[0052] Installation steps for Example 1:

[0053] When installing the roller blind, first rotate the rotating base 2 clockwise, causing the limiting member 4 to move away from the first limiting part 31, thus reserving space for the main body 3 to move axially. Then, press the main body 3 against one side of the wall with the rubber pad 63, causing the main body 3 to move axially to make room for the curtain rod and the beaded string controller 7. Press the beaded string controller 7 against the other side of the wall and adjust the position of the curtain rod to be parallel to the horizontal plane. Then, release the pressure on the main body 3, allowing the main body 3 to move back to its original position under the push of the spring 33. Then rotate the rotating base 2, and the limiting member 4, under the combined action of the thread and the second limiting part 32, moves axially until it presses against the first limiting part 31, preventing the main body 3 from moving towards the end of the beaded string controller 7, thus completing the installation. The operation is simple and convenient, and users can install it themselves, reducing costs. Moreover, it does not require drilling installation holes in the wall and will not damage the original decoration or building structure. When the user uses the roller blind, pulling the pull ball will cause the pull ball controller 7 to drive the first housing 1-1 to rotate. The first housing 1-1 rotates relative to the rotating seat 2. The thrust ball bearing 5 reduces the friction, so that the first housing 1-1 can be used with the pull ball without affecting the axial installation effect.

[0054] Example 2:

[0055] like Figure 8 and Figure 11 As shown, the difference between Embodiment 1 and Embodiment 2 is that in Embodiment 2, the outer shell is the second outer shell 1-2, and the non-drilling mounting component is suitable for installation on the pleated curtain. Since the pleated curtain does not require the rotating bead control 7, the second outer shell 1-2 does not need to rotate, so the thrust ball bearing 5 does not need to be set. At this time, the lower end of the spring 33 abuts against the inner bottom wall of the second outer shell 1-2. Part of the spring 33 is accommodated in the receiving cavity 21, and the other part is accommodated in the second outer shell 1-2.

[0056] like Figure 5 and 10As shown, the second shell 1-2 is also provided with the positioning pin 11, and the difference between the second shell 1-2 and the first shell 1-1 is that the second shell 1-2 is provided with the second limiting block 12.

[0057] As shown in FIG. 2, the rotating seat 2 is provided with the first shell 1-1, and the first shell 1-1 is provided with the first limiting block 11. Figure 8 As shown in FIG. 2, the rotating seat 2 is provided with the first shell 1-1, and the first shell 1-1 is provided with the first limiting block 11.

[0058] As shown in FIG. 2, the rotating seat 2 is provided with the first shell 1-1, and the first shell 1-1 is provided with the first limiting block 11. Figure 11 As shown in FIG. 2, the rotating seat 2 is provided with the first shell 1-1, and the first shell 1-1 is provided with the first limiting block 11.

[0059] The mounting shell 8 is provided with a slide rail, and the shielding shell 81 is provided with a sliding groove, and the slide rail and the sliding groove are in sliding connection, so that the shielding shell 81 can shield the non-punching mounting piece, avoid the mounting piece exposed, and be more beautiful.
