Description

Technical Field

[0001] The invention relates to the technical field of window decoration accessories, in particular to a height-adjustable roller blind mounting bracket. Background Art

[0002] When installing a roller blind, each end is rotated and positioned on two mounting brackets on the wall. During installation, due to installation errors or uneven wall surface, the two brackets may be at different heights. This can cause the roller blind's axis to be uneven, leading to the fabric shifting to one side during use and becoming stuck on the brackets.

[0003] In order to solve this technical problem, some height-adjustable mounting codes have appeared on the market, such as the Chinese utility model patent with publication number CN215632670U and the name "Adjustable Roller Blind Mounting Code". This patent solution includes a wall docking piece and a roller blind docking piece. The roller blind docking piece is provided with a bearing seat. The bearing seat and the roller blind docking piece are slidably connected. A position adjustment mechanism is provided between the bearing seat and the roller blind docking piece. The position adjustment mechanism includes a screw. The two ends of the screw can be rotatably fixed on the roller blind docking piece. The bearing seat is provided with a screw hole, and the nut and the screw are connected to the screw hole. After the roller blind is installed, the screw is twisted with a wrench to drive the bearing seat to rise or fall, so as to adjust the positioning position of one end of the roller blind. This patent solution requires the use of tools to operate during the adjustment work. If the roller blind needs to be fine-tuned in daily use, the tools must be prepared in advance, and the adjustment operation is very inconvenient.

[0004] Another example is the Chinese utility model patent with publication number CN2921252Y and name "Rolling Shaft Adjustment Structure". The patent scheme includes a fixed seat, a bearing seat, two rotating disks and two fixing parts; an elliptical guide groove and two arc-shaped slide grooves are formed on the fixed seat, and the two arc-shaped slide grooves are relatively arranged on the upper and lower sides of the elliptical guide groove; the bearing seat can be slid up and down in the elliptical guide groove of the fixed seat; a through hole, two perforations and several adjustment holes are formed on the rotating disk, the diameter of the through hole is smaller than the maximum diameter of the bearing seat, the two perforations are relatively arranged on the upper and lower sides of the through hole, and the several adjustment holes are arranged along the circumference of the rotating disk, and the two rotating disks are respectively mounted on both sides of the bearing seat through their through holes; the two fixing parts are relatively extended and positioned in the corresponding perforations of the two rotating disks and the corresponding arc-shaped slide grooves of the fixed seat. When in use, a tool is inserted into any relative adjustment hole on the rotating disk, and then the rotating disk is rotated, so that the two fixing parts on the rotating disk can slide and rise in the corresponding arc-shaped sliding groove along the lowest point to the highest point of the sliding groove, and at the same time, the entire set of rotating disks can be driven to move upward along with the two fixing parts, and the bearing seat is pulled by the rotating disk and is limited in the elliptical guide groove to move vertically upward. The vertical upward movement of the bearing seat can make the two ends of the roller shutter shaft at the same level. In this patent, the rotating disc, bearing seat, and fixed member are essentially combined to form a single, integrated moving seat. The rotating disc rotates and slides along the curved groove of the fixed seat, causing the entire moving seat to slide up and down relative to the fixed seat. Taking the connection structure between the lower fixed member and the curved groove as an example, since the curved groove is stationary, as the rotating disc rotates, the contact surface of the curved groove supporting the fixed member gradually tilts from flat to inclined. This causes the angle between the direction of the curved groove's force on the fixed member and the direction of gravity on the fixed member to gradually increase. This gradually increases the lateral force component on the fixed member, increasing the tendency of the fixed member to fall back. Consequently, as the moving seat rises higher, the rotating disc becomes increasingly difficult to drive. Therefore, this patent requires the use of two sets of opposed fixed members and curved grooves, resulting in high production costs. Furthermore, since there is no fixed contact point between the moving seat and the fixed seat, the rotating disc follows an arc-shaped trajectory during rotation. This makes it difficult for the user to precisely control the height of the moving seat, making adjustment very inconvenient. Summary of the Invention

[0005] The object of the present invention is to provide a height-adjustable roller shutter mounting code, which does not require the aid of tools during the adjustment operation, can accurately control the lifting and lowering amplitude of the connecting member, and is more convenient to use.

[0006] The technical solution adopted by the present invention is: a height-adjustable roller shutter mounting code, including a mounting seat, a connecting piece and an adjusting piece; the connecting piece is slidably mounted on the mounting seat, the sliding direction of the connecting piece is arranged vertically, and a roller shutter through-hole is formed on the connecting piece; the adjusting piece is rotatably mounted on the mounting seat, and the adjusting piece does not produce displacement relative to the mounting seat, the adjusting piece is transmission-connected to the connecting piece, and the adjusting piece drives the connecting piece to slide by rotation; a self-locking structure is provided between the adjusting piece and the mounting seat, and the self-locking structure uses elastic force (such as a ratchet structure, etc.) or friction force to fix the adjusting piece relative to the mounting seat in the absence of external force.

[0007] The working principle of the present invention is as follows:

[0008] When in use, the mounting seat is set on the wall, and one end of the roller shutter can be rotatably inserted into the roller shutter insertion hole of the connecting piece. When the roller shutter needs to be leveled, the adjusting piece is manually pushed to overcome the force of the self-locking structure and rotate, so that the connecting piece can be driven by the adjusting piece to slide vertically, thereby adjusting the height position of the end of the roller shutter to achieve leveling. The self-locking structure allows the adjusting piece to be fixed relative to the mounting seat without the action of external force, avoiding the adjusting piece being driven by the roller shutter fabric to rotate during daily use, and also preventing the roller shutter from sliding the connecting piece due to its own weight and driving the adjusting piece to rotate. Through such a design, the roller shutter mounting code does not require the aid of tools during the adjustment operation, and is more convenient to use. In addition, since the adjusting piece is rotatably mounted on the mounting seat, and the adjusting piece does not move relative to the mounting seat, there is a fixed rotating contact between the adjusting piece and the mounting seat, and the rotation trajectory of the adjusting piece is regular and fixed, which is conducive to accurately controlling the lifting and lowering amplitude of the connecting piece, and the adjustment operation is more convenient.

[0009] Furthermore, in a height-adjustable roller blind mounting bracket as described above, a supporting curved surface is formed on the adjusting member, and the supporting curved surface is a curved surface whose travel path gradually converges toward the direction of the adjusting member's rotation axis; a transmission boss is formed on the connecting member, and the transmission boss is supported on the supporting curved surface; the adjusting member rotates to cause the transmission boss to slide along the supporting curved surface to drive the connecting member to slide relative to the mounting seat. When the adjusting member rotates, the supporting curved surface is driven to rotate around the adjusting member's rotation axis, so that the supporting curved surface can maintain a flat contact surface to support the transmission boss, so that the angle between the direction of the force exerted by the supporting curved surface on the transmission boss and the direction of gravity of the transmission boss can be kept constant or nearly constant, so that the force structure of the transmission boss is stable, so that the rotation of the adjusting member does not become difficult as the adjustment range increases, and the adjustment operation is more convenient. When the supporting surface is properly designed, the transmission boss and the supporting surface can achieve self-locking of their relative positions through the principle of friction self-locking angle, further preventing the connecting part from sliding against the supporting surface due to possible external vibration and changing the original position of the connecting part.

[0010] Furthermore, as described above, a height-adjustable roller shutter mounting code is formed with a first limiting portion and a second limiting portion on the adjusting member, the first limiting portion is connected to one end of the supporting curved surface, and the second limiting portion is connected to the other end of the supporting curved surface, and the first limiting portion and the second limiting portion are used to limit the range of movement of the transmission boss.

[0012] Furthermore, as described above, a height-adjustable roller shutter mounting code has a mounting ring surface formed on the mounting seat; a mounting ring portion is formed on the adjusting member, and the mounting ring portion is rotatably mounted on the mounting ring surface; the self-locking structure is arranged between the mounting ring surface and the inner ring surface of the mounting ring portion.

[0014] Furthermore, in the aforementioned height-adjustable roller shutter mounting code, the side of the first snap-fitting protrusion facing the inner annular surface of the mounting ring portion of the adjusting member is an arc surface, and the side of the second snap-fitting protrusion facing the mounting annular surface of the mounting seat is an arc surface.

[0015] Furthermore, in the aforementioned height-adjustable roller shutter mounting bracket, a plurality of friction ribs are evenly distributed on the outer ring surface of the mounting ring portion of the adjusting member, and the length direction of the friction ribs is parallel to the rotation axis of the adjusting member.

DETAILED DESCRIPTION

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 8 The present invention provides a height-adjustable roller shutter mounting code according to an embodiment, comprising a mounting base 1, a connecting member 2 and an adjusting member 3; the connecting member 2 is slidably mounted on the mounting base 1, the sliding direction of the connecting member 2 is arranged vertically, and a roller shutter through-hole 21 is formed on the connecting member 2; the adjusting member 3 is rotatably mounted on the mounting base 1, and the adjusting member 3 does not displace relative to the mounting base 1, the adjusting member 3 is transmission-connected to the connecting member 2, and the adjusting member 3 drives the connecting member 2 to slide by rotation; a self-locking structure 4 is provided between the adjusting member 3 and the mounting base 1, and the self-locking structure 4 uses friction force to fix the adjusting member 3 relative to the mounting base 1 in the absence of external force.

[0032] The working principle of this embodiment is as follows:

[0033] When in use, the mounting base 1 is set on the wall, and one end of the roller shutter 5 is rotatably inserted into the roller shutter insertion hole 21 of the connecting member 2. When the roller shutter 5 needs to be leveled, the adjusting member 3 is manually pushed to overcome the force of the self-locking structure 4 and rotate, so that the connecting member 2 can be driven by the adjusting member 3 to slide vertically, thereby adjusting the height position of the end of the roller shutter 5 to achieve leveling. The self-locking structure 4 allows the adjusting member 3 to be fixed relative to the mounting base 1 without the action of external force, preventing the adjusting member 3 from being driven by the fabric of the roller shutter 5 to rotate during daily use, and also preventing the roller shutter 5 from sliding the connecting member 2 under its own weight and driving the adjusting member 3 to rotate. Through such a design, the roller shutter mounting code does not require the aid of tools during the adjustment operation, and is more convenient to use. In addition, since the adjusting member 3 is rotatably mounted on the mounting base 1, and the adjusting member 3 does not move relative to the mounting base 1, there is a fixed rotating contact between the adjusting member 3 and the mounting base 1, and the rotation trajectory of the adjusting member 3 is regular and fixed, which is conducive to accurately controlling the lifting amplitude of the connecting member 2, and the adjustment operation is more convenient.

[0034] like Figure 5 、 Figure 7 and Figure 8As shown, the adjusting member 3 is formed with a supporting curved surface 331, which is a curved surface whose travel path gradually converges toward the rotation axis of the adjusting member 3. The connecting member 2 is formed with a transmission boss 22, which is supported on the supporting curved surface 331. The adjusting member 3 rotates to cause the transmission boss 22 to slide along the supporting curved surface 331, thereby driving the connecting member 2 to slide relative to the mounting base 1. When the adjusting member 3 rotates, the supporting curved surface 331 is driven to rotate around the rotation axis of the adjusting member 3, so that the supporting curved surface 331 can maintain a smooth contact surface with the transmission boss 22. The angle between the direction of the force applied by the supporting curved surface 331 on the transmission boss 22 and the direction of the gravity of the transmission boss 22 remains constant or nearly constant, thereby stabilizing the force-bearing structure of the transmission boss 22. This ensures that the rotation of the adjusting member 3 does not become difficult as the adjustment range increases, making the adjustment operation more convenient.

[0035] like Figure 5 and Figure 7 As shown, the adjusting member 3 is formed with a first limiting portion 332 and a second limiting portion 333. The first limiting portion 332 is connected to one end of the supporting curved surface 331, and the second limiting portion 333 is connected to the other end of the supporting curved surface 331. The first limiting portion 332 and the second limiting portion 333 are used to limit the range of motion of the transmission boss 22. The provision of the first limiting portion 332 and the second limiting portion 333 prevents the adjusting member 3 from rotating excessively, causing the transmission boss 22 of the connecting member 2 to disengage from the supporting curved surface 331, thereby improving the reliability and safety of the roller blind installation code.

[0036] like Figure 5 and Figure 7 As shown, a transmission slot 33 is formed on the adjusting member 3. The lower sidewall of the transmission slot 33 serves as the supporting curved surface 331. One end surface of the transmission slot 33 serves as the first limiting portion 332, and the other end surface of the transmission slot 33 serves as the second limiting portion 333. The transmission boss 22 of the connecting member 2 is slidably disposed within the transmission slot 33 of the adjusting member 3. The formation of the transmission slot 33 prevents the transmission boss 22 of the connecting member 2 from disengaging from the adjusting member 3 due to changes in the orientation of the roller blind mounting bracket, making installation and transportation of the roller blind mounting bracket more convenient.

[0037] like Figures 2 to 7 As shown, the mounting seat 1 is formed with a mounting annular surface 123; the adjusting member 3 is formed with a mounting ring portion 31, which is rotatably mounted on the mounting annular surface 123; and the self-locking structure 4 is disposed between the mounting annular surface 123 and the inner surface of the mounting ring portion 31. This design makes the rotation of the adjusting member 3 more stable.

[0038] like Figure 2 、 Figure 3 、 Figure 6and Figure 7 As shown, the self-locking structure 4 includes a plurality of first snap-fitting protrusions 41 and a plurality of second snap-fitting protrusions 42. The plurality of first snap-fitting protrusions 41 are arranged on the mounting annular surface 123 around the axis of the mounting annular surface 123, and the plurality of second snap-fitting protrusions 42 are arranged on the inner annular surface of the mounting annular portion 31 around the axis of the mounting annular portion 31. Adjacent first snap-fitting protrusions 41 and second snap-fitting protrusions 42 are interlaced and interlocked, so that the adjusting member 3 is fixed relative to the mounting seat 1 without external force. This design allows the adjusting member 3 to rotate step by step, making the adjustment operation more convenient and precise.

[0039] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the first clamping protrusion 41 has a curved surface facing the inner annular surface of the mounting ring portion 31 of the adjusting member 3, and the second clamping protrusion 42 has a curved surface facing the mounting annular surface 123 of the mounting seat 1. When the adjusting member 3 is driven to rotate by an external force, the second clamping protrusion 42 is driven to move, causing the first clamping protrusion 41 and the second clamping protrusion 42 to squeeze and deform each other, so that the adjusting member 3 can rotate step by step relative to the mounting seat 1. By adopting the design of the first clamping protrusion 41 and the second clamping protrusion 42 with a curved surface structure, the stress on the first clamping protrusion 41 and the second clamping protrusion 42 is more dispersed, making the structure of the first clamping protrusion 41 and the second clamping protrusion 42 more stable, and making the relative sliding between the first clamping protrusion 41 and the second clamping protrusion 42 smoother, so that the rotation of the adjusting member 3 is smoother.

[0040] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, a plurality of friction ribs 34 are evenly distributed on the outer surface of the mounting ring portion 31 of the adjusting member 3. The length direction of the friction ribs 34 is parallel to the rotation axis of the adjusting member 3. The friction ribs 34 are used to increase the friction force of the outer surface of the mounting ring portion 31, making it easier for the user to push the adjusting member 3 to rotate.

[0041] like Figure 2 、 Figure 3 and Figure 6As shown, the mounting base 1 includes a base 11 and a positioning frame 12. The positioning frame 12 is detachably mounted on the base 11. The positioning frame 12 is formed with the mounting annular surface 123 and the first clamping protrusion 41. A positioning space is formed between the positioning frame 12 and the base 11. The mounting annular portion 31 of the adjusting member 3 has a positioning protrusion 32 formed on its inner wall. The positioning protrusion 32 has the transmission groove 33 formed on the positioning protrusion 32. The positioning protrusion 32 is slidably disposed in the positioning space to position the adjusting member 3 in the axial direction. This design makes the installation and removal of the adjusting member 3 more convenient.

[0042] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, an adjustment slide 121 is formed on the positioning frame 12. The length direction of the adjustment slide 121 is arranged vertically. The adjustment slide 121 is located on the inner side of the mounting surface ring 123. The adjustment slide 121 is formed with a clearance opening 122, which is connected to the positioning space. The connecting member 2 is slidably arranged in the adjustment slide 121, and the transmission boss 22 of the connecting member 2 is inserted into the transmission slot 33 on the positioning protrusion 32 of the adjusting member 3 through the clearance opening 122. Through this design, the connecting member 2 is slidably arranged in the surrounding of the mounting ring portion 31 of the adjusting member 3, making the connection structure between the mounting base 1, the adjusting member 3, and the connecting member 2 more compact, reducing the space occupied by the roller blind installation code.

[0043] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications, combinations, and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims.
