Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a curtain installation structure that does not require drilling and a curtain. Background Technology

[0002] Accordion blinds, also known as honeycomb blinds, are decorative curtains with a honeycomb-like hollow structure, named for their accordion-like pleats. Their design allows air to be trapped for temperature control, and they offer heat insulation, sound insulation, UV protection, and anti-static properties. Early versions were primarily manually operated, but later blackout, semi-blackout, and motorized models were developed. Blackout blinds use airtight fabrics and are suitable for private spaces such as bedrooms; semi-blackout blinds combine light and decoration and are commonly found in bathrooms and dining rooms.

[0003] Some existing curtain products, such as honeycomb blinds, require drilling holes in the wall and then fixing the upper beam bracket of the curtain with bolts and other parts. Drilling is troublesome, installation is time-consuming and laborious, and bolt holes are left on the wall, damaging the wall and affecting its integrity. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a curtain installation structure that eliminates the need for drilling, comprising an upper beam support and a mounting bracket assembly. Two mounting bracket assemblies are symmetrically arranged at both ends of the upper beam support. Each mounting bracket assembly includes a housing and a sliding bracket component slidably mounted on the housing in a horizontal direction. The housing is provided with an adjustment mechanism for adjusting the sliding position of the sliding bracket component. The adjustment mechanism includes a rotating component, an output gear, and a transmission component connecting the rotating component and the output gear. The sliding bracket component is provided with a rack meshing with the output gear. The rotating component is rotatable in its circumferential direction and slidable in its axial direction. A first compression spring abuts between the output gear and the rotating component. The rotating component is provided with a positioning protrusion, and the housing is provided with a positioning groove corresponding to the positioning protrusion.

[0005] During installation, an external force drives the rotating component to slide axially, causing the positioning protrusion to disengage from the positioning groove. The external force also drives the rotating component to rotate circumferentially. The rotating component drives the output gear to rotate via the transmission component. The output gear drives the sliding frame component to slide towards the outer wall via the rack until the sliding frame component abuts against the wall. The external force releases the rotating component, and the rotating component slides back to its original position under the elastic force of the first compression spring, so that the positioning protrusion engages with the positioning groove to maintain the abutting force of the sliding frame component against the wall. This utility model's curtain installation structure eliminates the need for drilling holes in the wall. By adjusting the position of the sliding frame component through an adjustment mechanism, the sliding frame component is fixed against the wall without the need for drilling holes, making installation more convenient and preserving the integrity of the wall.

[0006] Optionally, the rack extends horizontally, and the sliding frame component includes a main frame and a telescopic frame that slides horizontally on the main frame. The telescopic frame is located at one end of the main frame near the wall, and a second compression spring abuts against the telescopic frame and the main frame. An anti-slip pad is provided on the side of the telescopic frame away from the main frame.

[0007] Optionally, the telescopic frame is provided with a buckle, and the main frame is provided with a limiting groove corresponding to the buckle. The buckle is slidably placed in the limiting groove in the horizontal direction. The main frame is provided with a first abutting part, and the telescopic frame is provided with a second abutting part corresponding to the first abutting part.

[0008] Optionally, the transmission component includes a transmission gear, which includes an integrally formed first transmission gear and a second transmission gear. The first transmission gear and the second transmission gear are coaxially arranged. The rotating component is integrally provided with a first gear portion that meshes with the first transmission gear. The output gear is integrally provided with a second gear portion that meshes with the second transmission gear. The output gear and the second gear portion are coaxially arranged.

[0009] Optionally, the diameter of the first gear portion is smaller than the diameter of the first transmission gear, the diameter of the first transmission gear is larger than the diameter of the second transmission gear, the diameter of the second gear portion is larger than the diameter of the second transmission gear, and the diameter of the second gear portion is larger than the diameter of the output gear.

[0010] Optionally, multiple positioning protrusions are arranged in annularly at equal intervals, and multiple positioning grooves are arranged in annularly at equal intervals, with the number of positioning protrusions being the same as the number of positioning grooves.

[0011] Optionally, a first guide slope is provided on both sides of the positioning protrusion, and a second guide slope corresponding to the first guide slope is provided on both sides of the opening of the positioning groove.

[0012] Optionally, the housing is provided with a mounting shaft, the output gear is rotatably sleeved on the mounting shaft, the first compression spring is sleeved on the mounting shaft, the sliding frame component is provided with a sliding groove, and the mounting shaft is slidably engaged with the sliding groove.

[0013] Optionally, the curtain no-drill installation structure further includes a rotating handle for driving the rotating component to rotate. The rotating component is provided with a insertion slot. The rotating handle includes a rotating shaft and a handle rotatably sleeved on the rotating shaft. The rotating shaft has a raised arc-shaped positioning part. The handle has multiple positioning grooves along the circumferential direction that are adapted to engage with the arc-shaped positioning part. The rotating shaft is provided with a insertion post that can be detachably inserted into the insertion slot. The shape of the insertion post matches the shape of the insertion slot. When the insertion post is inserted into the insertion slot, an external force axially pushes the handle. The handle drives the rotating component to slide axially through the rotating shaft, so that the positioning protrusion disengages from the positioning slot. At this time, the external force circumferentially rotates the handle to drive the rotating component to rotate synchronously. When the handle is rotated, the rotating shaft provides resistance to the handle in the circumferential direction. When the resistance exceeds a preset value, the handle rotates freely relative to the rotating shaft.

[0014] Compared to existing technologies, the curtain installation structure of this invention, which eliminates the need for drilling, adjusts the position of the sliding frame component through an adjustment mechanism, thereby fixing the sliding frame component firmly against the wall without the need for drilling holes in the wall. This makes installation more convenient and preserves the integrity of the wall. The curtain installation structure also includes a rotating handle for rotating the rotating component. The rotating handle acts as a lever arm extension rod, significantly increasing the rotation radius for user operation, making operation more effortless and convenient. After installation, the user can easily remove the rotating handle from the rotating component without affecting the aesthetics of the curtain.

[0015] In addition, this utility model also provides a curtain, including the above-mentioned curtain no-drill installation structure. This curtain also has the same beneficial effects as the above-mentioned curtain no-drill installation structure, which will not be described in detail here. Attached Figure Description

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0032] 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.

[0033] See Figures 1-12 This utility model provides a curtain installation structure that does not require drilling, including an upper beam support 1 and a mounting bracket assembly 2. Two mounting bracket assemblies 2 are symmetrically arranged and are respectively arranged at both ends of the upper beam support 1. The mounting bracket assembly 2 includes a housing 3 and a sliding bracket component 4 that is slidably arranged on the housing 3 in the horizontal direction. The housing 3 is provided with an adjustment mechanism for adjusting the sliding position of the sliding bracket component 4. The adjustment mechanism includes a rotating component 5, an output gear 6, and a transmission component connected between the rotating component 5 and the output gear 6. The sliding bracket component 4 is provided with a rack 401 that meshes with the output gear 6. The rotating component 5 can rotate in its circumferential direction and slide in its axial direction. A first compression spring 7 abuts between the output gear 6 and the rotating component 5. The rotating component 5 is provided with a positioning protrusion 501. The housing 3 is provided with a positioning groove 301 corresponding to the positioning protrusion 501.

[0034] During installation, first place the upper beam bracket 1 inside the window frame. Taking the mounting bracket assembly 2 at one end (right end) as an example, external force drives the rotating part 5 at this end to slide axially, so that the positioning protrusion 501 disengages from the positioning groove 301. External force drives the rotating part 5 to rotate circumferentially. The rotating part 5 drives the output gear 6 to rotate through the transmission component. The output gear 6 drives the sliding bracket assembly 4 to slide towards the outer wall 10 through the rack 401 until the sliding bracket assembly 4 is pressed against the wall 10. External force releases the rotating part 5, and the rotating part 5 slides back to its original position under the elastic force of the first compression spring 7, so that the positioning protrusion 501 disengages from the positioning groove 301. 501 engages with positioning groove 301 to maintain the clamping force of the sliding bracket component 4 on this end against the wall 10; the installation principle of the mounting bracket assembly 2 on the other end is the same. When the sliding bracket component 4 on the left end is clamped against the left end wall and the sliding bracket component 4 on the right end is clamped against the right end wall, the upper beam bracket 1 is fixedly installed in the window frame, thus completing the installation of the curtain; the curtain installation structure of this utility model without drilling holes adjusts the position of the sliding bracket component through the adjustment mechanism, so that the sliding bracket component is clamped against the wall for fixation, without the need to drill holes in the wall, making the installation more convenient and preserving the integrity of the wall.

[0035] See Figure 3 , Figure 4 and Figure 8 The rack 401 extends horizontally, and the sliding frame component 4 includes a main frame 41 and a telescopic frame 42 that slides horizontally on the main frame 41. The telescopic frame 42 is located at one end of the main frame 41 near the wall 10. A second compression spring 43 abuts between the telescopic frame 42 and the main frame 41. An anti-slip pad 44 is provided on the side of the telescopic frame 42 away from the main frame 41. The pre-installation function of the curtain is realized through the telescopic frame 42.

[0036] The pre-installation steps in this embodiment are as follows: Before installation, the telescopic frame 42 is in an extended state. At this time, the telescopic frames 42 at both ends are compressed inward so that the entire upper beam support 1 can be installed into the window frame. At this time, the second compression spring 43 drives the telescopic frame 42 to extend and abut against the wall 10 on the same side. The anti-slip pad 44 on the telescopic frame 42 contacts the wall surface to achieve an anti-slip effect. At this time, the upper beam support 1 is pre-installed in the window frame to temporarily support the weight of the entire curtain and prevent it from falling, achieving "aerial hovering" when operated by a single person, which greatly simplifies the installation process and facilitates subsequent installation steps. It should be noted that: after pre-installation, the telescopic frame 42 is not completely pressed against the wall 10, and a subsequent installation step to fully press it against the wall is required. After completing the pre-installation, taking the mounting bracket assembly 2 at one end as an example, external force drives this... One end of the rotating component 5 slides axially to disengage the positioning protrusion 501 from the positioning groove 301. An external force drives the rotating component 5 to rotate circumferentially. The rotating component 5 drives the output gear 6 to rotate through the transmission component. The output gear 6 drives the sliding frame component 4 to slide towards the outer wall 10 through the rack 401 until the sliding frame component 4 presses against the wall 10. An external force releases the rotating component 5, and the rotating component 5 slides back to its original position under the elastic force of the first compression spring 7, so that the positioning protrusion 501 engages with the positioning groove 301 to maintain the pressing force of the sliding frame component 4 against the wall 10 at this end. The installation principle of the mounting bracket assembly 2 at the other end is the same as above. When the sliding frame component 4 at the left end presses against the left end wall and the sliding frame component 4 at the right end presses against the right end wall, the upper beam bracket 1 is fixedly installed in the window frame, thus completing the installation of the curtain.

[0037] See Figure 3 , Figure 4 , Figure 6 and Figure 8The telescopic frame 42 is equipped with a buckle 421, and the main frame 41 is equipped with a limiting groove 411 corresponding to the buckle 421. The buckle 421 slides horizontally into the limiting groove 411. Through the cooperation of the buckle 421 and the limiting groove 411, the telescopic frame 42 is prevented from completely detaching from the main frame 41 during installation, ensuring reliable use. The main frame 41 is equipped with a first abutting part 412, and the telescopic frame 42 is equipped with a second abutting part 422 corresponding to the first abutting part 412. After pre-installation, the rotating part 5 drives the main frame 41 to move towards the wall, so that the first abutting part 412 of the main frame 41 abuts against the second abutting part 422. At this time, the rotating part 5 continues to rotate, so that the main frame 41 applies a pushing force towards the wall to the telescopic frame 42, so that the telescopic frame 42 is completely pressed against the wall to complete the installation step and ensure a secure installation.

[0038] See Figure 5 , Figure 6 , Figure 8 and Figure 9 The transmission components include a transmission gear 8, which comprises an integrally formed first transmission gear 81 and a second transmission gear 82, coaxially arranged. A first gear portion 51, meshing with the first transmission gear 81, is integrally formed on the rotating component 5. A second gear portion 61, meshing with the second transmission gear 82, is integrally formed on the output gear 6. The output gear 6 and the second gear portion 61 are coaxially arranged. The transmission is achieved through a gear structure, which is simple in structure and reliable in transmission. The diameter of the first gear portion 51 is smaller than the diameter of the first transmission gear 81, and the diameter of the first transmission gear 81 is larger than the diameter of the second transmission gear 82. The diameter of the second gear 61 is larger than the diameter of the second transmission gear 82, and the diameter of the second gear 61 is larger than the diameter of the output gear 6; thus, the function of multi-stage gear reduction is realized, which slows down the sliding extension speed of the main frame 41 to facilitate fine adjustment; specifically, because the main frame 41 is greatly decelerated, the user needs to rotate the rotating part 5 many times before the main frame 41 moves outward a little distance. This high transmission ratio allows the user to make fine adjustments to the tightness. The user can slowly and finely extend the main frame 41 to drive the telescopic frame to press against the wall until the tightness is appropriate, which improves the success rate and quality of installation.

[0039] The transmission component of this embodiment is suitable for curtain products with a large vertical height of the upper beam bracket 1 (sufficient vertical installation space); when the vertical height of the upper beam bracket 1 of the curtain product is small (limited vertical installation space), but the length in the front-to-back direction is long, the number of gears in the front-to-back direction can be increased to achieve multi-stage reduction transmission. By increasing the number of gears in the front-to-back direction, the diameter of each transmission gear can be reduced to meet design requirements; see reference. Figure 1 The vertical direction of the upper crossbeam support 1 is the Z-axis direction, and the front-to-back direction of the upper crossbeam support 1 is the Y-axis direction.

[0040] See Figure 6 , Figure 10 , Figure 11 and Figure 12 Multiple positioning protrusions 501 and multiple positioning grooves 301 are arranged in a ring at equal intervals. The number of positioning protrusions 501 and positioning grooves 301 is the same. The multiple positioning protrusions 501 and positioning grooves 301 are matched to provide multi-point positioning function and improve adjustment accuracy. At the same time, the multiple positioning protrusions 501 and positioning grooves 301 engage simultaneously, which can evenly distribute the force after locking to multiple contact points, disperse stress, make the structure less prone to damage, and extend service life. The two positioning protrusions 501... Each side is provided with a first guide slope 5011, and the two sides of the positioning groove 301 are provided with a second guide slope 3011 corresponding to the first guide slope 5011. During installation, the rotating part 5 is pushed axially to make the positioning protrusion 501 disengage from the positioning groove 301. When the external force releases the rotating part 5, the positioning protrusion 501 can fall back into the corresponding positioning groove 301 smoothly through the cooperation of the first guide slope 5011 and the second guide slope 3011, so that the rotating part 5 can be smoothly reset and locked under the action of the first compression spring 7.

[0041] See Figure 6 and Figure 9 The housing 3 is provided with a mounting shaft 31. The output gear 6 is rotatably sleeved on the mounting shaft 31, and the first compression spring 7 is sleeved on the mounting shaft 31. The mounting shaft 31 provides support for the rotational movement of the output gear 6, and at the same time provides positioning for the first compression spring 7 during installation, so that the first compression spring 7 is not prone to large displacement, thus ensuring precise elastic force. The mounting shaft 31 has multiple functions, a compact structure, and saves costs. The sliding frame component 4 is provided with a sliding groove 402. The mounting shaft 31 slides in the sliding groove 402, avoiding interference between the sliding frame component 4 and the mounting shaft 31 when sliding. The structural design is reasonable.

[0042] See Figure 1 and Figure 2The curtain no-drill installation structure also includes a rotating handle 9 for driving the rotating component 5 to rotate. The rotating component 5 is provided with a insertion slot 502. The rotating handle 9 includes a rotating shaft 91 and a handle 92 rotatably sleeved on the rotating shaft 91. The rotating shaft 91 is provided with a protruding arc-shaped positioning part 911. The handle 92 is provided with a plurality of positioning grooves 921 along the circumferential direction that are adapted to engage with the arc-shaped positioning part 911. The rotating shaft 91 is provided with an insertion post 901 that can be detachably inserted into the insertion slot 502. The shape of the insertion post 901 is adapted to the shape of the insertion slot 502. When the plug pin 901 is inserted into the plug slot 502, an external force axially pushes the handle 92. The handle 92 drives the rotating component 5 to slide axially through the rotating shaft 91, so that the positioning protrusion 501 disengages from the positioning slot 301. At this time, the external force rotates the handle 92 circumferentially, so that the rotating component 5 rotates synchronously. When the handle 92 is rotated, the rotating shaft 91 provides resistance to the handle 92 in the circumferential direction. When the resistance exceeds the preset value, the handle 92 rotates freely relative to the rotating shaft 91. This prevents the user from using excessive rotational force, which could lead to breakage or damage to transmission components such as the output gear 6 and rack 401. For long service life, it should be noted that the preset value is the critical value when the handle 92 and the rotating shaft 91 are idling. Under this preset value, the transmission components such as the output gear 6 and rack 401 are under stress within a safe range and will not break or be damaged. In this embodiment, multiple arc-shaped positioning parts 911 are evenly spaced along the circumference. In this embodiment, three arc-shaped positioning parts 911 are provided. An annular wall 912 is provided on the rotating shaft 91, and the arc-shaped positioning parts 911 are integrally formed on the outer side of the annular wall 912. During design, the preset value can be determined by adjusting the size of the annular wall 912. The thickness and height of the arc-shaped positioning part 911 are controlled. The thicker the annular wall 912 and the higher the height of the arc-shaped positioning part 911, the larger the preset value; the thinner the annular wall 912 and the lower the height of the arc-shaped positioning part 911, the smaller the preset value. In this embodiment, the handle 92 is rotatably connected to the rotating shaft 91. The rotating handle 9 acts as a lever arm extension rod, significantly increasing the rotation radius of the user's operation, making the operation more effortless and convenient. After installation, the user can easily remove the rotating handle 9 from the rotating part 5 without affecting the aesthetics of the curtain.

[0043] The curtain installation structure without drilling in this invention adjusts the position of the sliding frame component through an adjustment mechanism, thereby fixing the sliding frame component firmly against the wall without drilling holes in the wall, making installation more convenient and preserving the integrity of the wall. The curtain installation structure without drilling also includes a rotating handle for driving the rotating component to rotate. The rotating handle acts as a lever arm extension rod, significantly increasing the rotation radius for user operation, making operation more effortless and convenient. After installation, the user can easily remove the rotating handle from the rotating component without affecting the appearance of the curtain.
