Description

Technical Field

[0001] This utility model relates to the field of curtain accessories, specifically a curtain sash. Background Technology

[0002] A curtain spool is an accessory for beaded roller blinds. The blind tube is fitted onto the rotating shaft of the spool and rotates axially with the spool to roll up and unroll the blind. Due to its simple structure and ease of use, it is widely used.

[0003] During installation, both ends of the curtain roller are fitted with retainers, which are then fixed to the wall above the window with screws to position the curtain. However, with conventional retainers, once fixed with screws, the retainers must be removed before the user can disassemble the roller or change the curtain. Because the curtain is installed high up, removing the screws becomes difficult, and repeated disassembly and reassembly often leads to the screw holes widening and loosening, eventually causing the holes to become unusable. Therefore, a curtain retainer that allows for easy installation and removal of the roller is needed. Utility Model Content

[0004] This utility model provides a curtain head with a detachable pivot. The pivot and roller tube can be removed without removing screws, which greatly simplifies the assembly and disassembly process of roller curtains.

[0005] A curtain head includes a rotating support post, a mounting bracket, and a mounting bracket.

[0006] The mounting bracket includes a rotating mounting bracket and a fixed mounting bracket. The fixed mounting bracket has a raised fixed gear disc on one side, with continuous convex teeth on its outer circumference. One side of the rotating mounting bracket is recessed inwards, rotating and fitting with the fixed mounting bracket. The recess has a central opening with continuous concave teeth on its wall, forming a ring-shaped rotating gear ring. The rotating gear ring and the fixed gear disc are coaxially assembled; their tooth surfaces abut against each other when no external force is applied. When the rotating mounting bracket is subjected to force and rotates around its axis, the rotating gear ring deforms, allowing for skipped tooth rotation. Both the rotating and fixed mounting brackets have through slots extending from the center to the outer side. One end of the rotating support column is movably mounted on the end of the through slot of the fixed mounting bracket near the center.

[0007] The rotating support column includes an outer rotating sleeve and an inner support shaft. The outer rotating sleeve has a central hole, and the rotating sleeve is mounted on the inner support shaft.

[0008] The fixed gear plate has axial protrusions that are embedded and fixed on the mounting bracket.

[0009] The mounting bracket is fixedly connected to the mounting surface by bolts.

[0010] As a further improvement of this utility model, an arc-shaped limiting block is formed on the fixed card holder. The limiting block is located on the outside of the fixed gear plate and is arranged coaxially with it. The limiting block is located on the opposite side of the through slot opened on the fixed gear plate.

[0011] As a further improvement of this utility model, the rotating card seat is provided with an arc-shaped sliding groove. The sliding groove is located on the outer side of the rotating gear ring on the same axis. The sliding groove is fitted and cooperated with the limiting block. The rotating card seat can rotate coaxially around the fixed card seat through the sliding groove under the limiting guidance of the limiting block.

[0012] As a further improvement of this utility model, when the through grooves of the rotating card seat and the fixed card seat are aligned, one end of the sliding groove abuts against one end of the limiting block. When the other ends of the sliding groove and the limiting block abut against each other, the through grooves of the rotating card seat and the fixed card seat intersect, and the rotating card seat blocks the opening of the through groove of the fixed card seat.

[0013] As a further improvement of this utility model, screws are installed around the mounting bracket and the embedded end of the fixed gear plate to connect and fix the two, so that the fixed gear plate cannot rotate relative to the embedded end.

[0014] As a further improvement of this utility model, when the fixed gear plate is connected to the mounting bracket screw, the through groove of the fixed card seat points obliquely upward, opposite to the direction of gravity and with an included angle.

[0015] As a further improvement of this utility model, the through slots opened on the rotating card holder and the fixed card holder are of equal width and both point at a 45-degree angle upwards. The opening of the through slot of the rotating card holder extends upwards and widens, vertically aligning with the upper end of the slot opening of the through slot of the fixed card holder.

[0016] As a further improvement of this utility model, a groove is formed at one end of the inner support shaft near the card seat. The rotating and fixing slots on the card seat and the fixed card seat have a protrusion extending into the groove at the edge near the inner support shaft, forming a stepped groove edge. The groove of the inner support shaft slides into the stepped protrusion of the groove.

[0017] As a further improvement of this utility model, it also includes a protective sleeve, which is fitted onto the embedded end of the fixed gear plate and the mounting bracket to cover and shield the surface of the embedded part.

[0018] The present invention relates to a curtain head, wherein one end of a rotating support column is fitted inside the curtain roller tube, and the other end is movably engaged in the through groove of the bracket. The through grooves are aligned and connected, and the rotating support column can be disassembled by sliding along the through groove. The through grooves are staggered and blocked, and the rotating support column is restricted and fixed in the through groove.

[0019] The rotating support column is engaged with the stepped protrusion in the slot of the fixed bracket through the groove at the end of the column, which can prevent the support column from axially shifting, thereby preventing the curtain roller from slipping off.

[0020] The rotating gear ring and the fixed gear disc are fixed by mutual abutment through the tooth surfaces. By rotating and adjusting the position of the tooth surfaces, the through grooves of the two can be easily blocked or aligned and opened, thus realizing the convenient disassembly and assembly of the rotating support column. In actual installation and use, when users disassemble and assemble curtain rollers at high places, it can greatly simplify the disassembly and assembly process and facilitate the user's daily maintenance.

[0035] Specific Implementation Example 1: As shown in the example Figure 1 The curtain head shown is characterized by comprising a rotating support column 1, a card seat 2, and a mounting bracket 3.

[0036] like Figure 2 As shown, the rotating support column 1 includes an outer rotating sleeve 101 and an inner support shaft 102.

[0037] The outer rotating sleeve 101 is a cylinder with a through hole at its center, and a radially protruding step is formed at the left end. On the outer wall of the cylinder of the outer rotating sleeve 101, there are 6 support plates distributed evenly at intervals in a radiating pattern. When the outer rotating sleeve 101 is installed with the curtain roller tube, the top of the support plate abuts against the inner wall of the curtain roller tube and is tightened and fixed.

[0038] The inner support shaft 102 is a cylindrical part with a radially protruding step on the right side. The column at the right end is fitted into the axial through hole of the outer rotating sleeve 101 during installation. The right end face of the protruding step of the inner support shaft 102 abuts against the left end face of the outer rotating sleeve 101, and the outer rotating sleeve 101 can rotate freely axially around the inner support shaft 102.

[0039] like Figures 3-6 As shown, the card holder 2 includes a rotating card holder 201 and a fixed card holder 202.

[0040] The rotating bracket 201 is a disc part, with a circular recess along the axial direction at the center of one end face. An axial through hole is opened at the center of the recess, and continuous arc-shaped concave teeth are made on the wall of the through hole, forming a rotating gear ring 2011 structure. The fixed bracket 202 is a disc part, with only a circular protrusion along the axial direction at the center of one end face. Continuous convex teeth are made around the side wall of the protrusion, forming a fixed gear disc 2021 structure.

[0041] Both the rotating bracket 201 and the fixed bracket 202 have through slots extending radially from the center, and the widths of the through slots are equal. Figure 5 As shown in Figure 6, the rotating bracket 201 is a ring with a notch, and the fixed bracket 202 is a disc with a through groove.

[0042] When the rotating bracket 201 and the fixed bracket 202 are assembled, the rotating gear ring 2011 and the fixed gear disk 2021 are installed coaxially, and the fixed gear disk 2021 is embedded in the rotating gear ring 2011. When there is no external force, the tooth surfaces of the two can abut against each other and be fixed. When the rotating bracket 201 is subjected to force and rotates around the axis, the tooth surface of the rotating gear ring 2011 can produce a small deformation, and the tooth surfaces of the two no longer abut against each other and are fixed. The rotating gear ring 2011 performs skipped tooth rotation.

[0043] The fixed gear 2021 has an axial square protrusion at the center on the side near the rotating gear ring 2011. The mounting bracket 3 is made of bent metal plate, and a square hole matching the protrusion on the fixed gear 2021 is opened at the center of one side of the plate. The square protrusion of the fixed gear 2021 is embedded and fixed in the square hole of the mounting bracket 3, and screws are installed around the embedded part to achieve a firm connection between the fixed gear 2021 and the mounting bracket 3.

[0044] Working principle:

[0045] like Figures 8-10 As shown, the outer rotating sleeve 101 is fitted onto the outside of the inner support shaft 102. The left end of the inner support shaft 102 is placed on the end of the through groove of the fixed bracket 202 near the center. The through grooves of the rotating bracket 201 and the fixed bracket 202 are interlocked. The rotating bracket 201 blocks the opening of the through groove of the fixed bracket 202, and the left end of the inner support shaft 102 is restricted in the through groove and cannot slide out from the opening end of the through groove.

[0046] Rotating the locator 201 axially causes a slight deformation in the tooth surface of the rotating gear ring 2011 on the locator 201. The rotating gear ring 2011 and the fixed gear disc 2021 no longer abut against each other, and the rotating gear ring 2011 performs skipped-tooth rotation. When the through slots of the rotating locator 201 and the fixed locator 202 are aligned, the left end of the inner support shaft 102 can slide out along the aligned through slots for quick disassembly. Conversely, by reversing the operation, the inner support shaft 102 can be quickly installed.

[0047] Specific Embodiment Two: Based on Specific Embodiment One, a groove is formed at one end of the inner support shaft 102 near the card holder 2. The through slots on the rotating and fixed card holder 201 and the fixed card holder 202 are rotated. A protrusion extending into the groove is formed at the edge near the inner support shaft 102, creating a stepped groove edge. The groove of the inner support shaft 102 slides into the stepped protrusion of the groove, achieving circumferential positioning of the inner support shaft 102 and preventing slippage.

[0048] Specific Embodiment Three: Based on Specific Embodiment Two, an arc-shaped limiting block 2022 is formed on the fixed card seat 202. The limiting block 2022 is located on the outer coaxial side of the fixed gear disk 2021, opposite to the through slot opening of the fixed gear disk 2021. The angle between the two ends of the limiting block 2022 and the axis is 90 degrees. An arc-shaped sliding groove 2012 is formed on the rotating card seat 201. The sliding groove 2012 is located on the outer coaxial side of the rotating gear ring 2011, extending from one end of the through slot on the rotating card seat 201. The angle between the two ends of the sliding groove 2012 and the axis is 180 degrees.

[0049] The slide groove 2012 and the limiting block 2022 are fitted together, such as... Figure 9 As shown, when the limiting block 2022 abuts against the left side of the slide groove 2012, the through groove of the fixed card seat 202 is blocked by the rotating card seat 201, and the angle between the rotating card seat 201 and the through groove of the fixed card seat 202 is 90 degrees. Figure 10 As shown, when the limiting block 2022 abuts against the right side of the slide groove 2012, the through groove of the fixed bracket 202 aligns with the through groove of the rotating bracket 201, and the angle between the through grooves of the rotating bracket 201 and the fixed bracket 202 is 0 degrees. Through the cooperation of the slide groove 2012 and the limiting block 2022, the user can easily adjust the blocking or connecting state of the through groove by simply rotating the bracket 201 to its limit position during assembly and disassembly, without needing to climb or visually observe the rotation angle.

[0050] Specific Implementation Example 4: As shown in the example Figure 11 In the actual installation scenario shown, after the curtain header is installed, the fixing screws on the mounting bracket 3 are exposed, which is prone to rusting and affects the appearance. Figures 12-13 As shown, the sheath 4 is fitted onto the outside of the mounting bracket 3 with a snap fastener, covering and concealing the fixing screws on the mounting bracket 3. This provides rust protection for the screws while ensuring the aesthetics of the installation.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the invention. All variations, modifications and substitutions within the spirit and principle of the present invention are within the protection scope of the present utility model.
