Description

Technical Field

[0001] This invention relates to the field of roller blinds, and particularly to a roller blind and its assembly / disassembly components that are easy to assemble and disassemble. Background Technology

[0002] In modern interior design and functionality, curtains, as an important element for light blocking and decoration, are increasingly valued for their convenience, aesthetics, and functionality. Traditional curtain installation and removal processes are often complex and time-consuming, especially when cleaning or replacing the fabric. Roller blinds, due to their simple structure and convenient operation, have gained widespread use in offices, homes, and other environments.

[0003] However, ordinary roller blinds often have some problems in daily use. With the development of technology, technicians in related fields have also made a lot of optimizations to roller blinds. For a more accurate comparison, Chinese Patent No. CN118390948A discloses auxiliary installation parts, installation components and light-blocking devices for standard-sized roller blinds, including a connecting part and at least one installation part. The connecting part is located at the end and is connected to the roller blind mounting bracket, and the installation part is connected to the window frame, etc. In use, the curtain assembly is installed by the cooperation of the connecting part, the installation part and the auxiliary installation parts, and the problem of matching the width of the curtain assembly with the window frame is solved by adjusting the relative positions of the connecting part, the installation part and the auxiliary installation parts.

[0004] However, the above-mentioned device still has some shortcomings in actual use: 1. The above-mentioned device installs the curtain assembly by positioning it between the first and second supports and overlapping the connecting parts of the first and second auxiliary mounting parts with the auxiliary mounting parts, and tightening it with multiple screws threaded through. However, when the position of the curtain assembly needs to be adjusted according to the width of the window frame, workers need to climb to a high place to remove the screws that have been tightened one by one, adjust the relative position between the first and second supports according to the width of the window frame, and then tighten the screws again. Adjusting the position of the curtain assembly is time-consuming and labor-intensive.

[0005] 2. Since the curtain assembly is directly connected to the curtain fabric via a roller, when the curtain fabric needs to be removed or replaced, both the roller and the curtain fabric need to be removed from the window frame at the same time. However, the two ends of the roller are limited by the first bracket and the second bracket respectively. Therefore, when the curtain fabric needs to be removed, the first bracket and the second bracket also need to be removed from the auxiliary mounting parts at the same time, which is time-consuming and laborious.

[0006] Therefore, based on the above points, there is still room for improvement in existing roller blinds. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a roller blind that is easy to assemble and disassemble, comprising an mounting rod and a roller blind fabric. The mounting rod and the roller blind fabric are connected by a limiting head. After the limiting head restricts one side of the roller blind fabric onto the mounting rod, the limiting head and the mounting rod cooperate to form a roller to limit the installation of the roller blind fabric. By rotating the mounting rod and the limiting head, the roller blind fabric can be wound and unwound.

[0008] A positioning hole is provided on any side of the roller blind fabric. The mounting rod and the mounting head together form a mounting groove for inserting one end of the roller blind fabric. A positioning protrusion is symmetrically connected to the mounting head, inserted into the positioning hole to position and install the roller blind fabric. The positioning protrusion passes through the mounting rod. The mounting head and the mounting rod are detachably installed together by an elastic element.

[0009] Preferably, the elastic element includes symmetrically opened limiting grooves at both ends of the mounting rod that communicate with the mounting slot, a positioning protrusion inserted into the limiting groove, a limiting protrusion corresponding to the position of the mounting head relative to the limiting groove, an elastic protrusion connected to the limiting protrusion and inserted into the limiting groove, and a groove adapted to the elastic protrusion communicating in the limiting groove.

[0010] Preferably, the positioning protrusion includes a driven slide bar that is inserted into the limiting through groove. The side of the driven slide bar near the mounting groove is connected to an extension protrusion that matches the positioning hole on the roller blind. The extension protrusion extends out of the limiting through groove and into the mounting groove to limit the roller blind.

[0011] Preferably, the driven slider is also symmetrically connected with guide sliders inserted on the mounting rod to limit the sliding path of the connected driven sliders.

[0012] Preferably, the mounting head includes a connecting protrusion inserted into the mounting rod, a connecting end cap connected to the end of the connecting protrusion away from the mounting rod, a mounting groove formed on the connecting end cap, and a limiting protrusion connected to the connecting end cap.

[0013] Preferably, the diameter of the connecting end cap corresponds to the diameter of the mounting rod.

[0014] Preferably, the connecting end cap has a cover groove, the connecting protrusion is disposed in the cover groove, and the cover groove is connected to the mounting groove on the connecting end cap.

[0015] Preferably, the mounting groove on the connecting end cap is positioned towards the side closer to the mounting rod, and the mounting groove and the cover groove are arranged in a stepped manner.

[0016] In addition, the present invention also provides a disassembly and assembly assembly, including a connecting part that mates with the mounting head, the connecting part being mounted on a wall for assembling the mounting head and the mounting rod.

[0017] Preferably, the connecting part includes an extension rotating rod connected to the side of the mounting head away from the mounting rod, and a limiting frame with a U-shaped structure is sleeved on the extension rotating rod.

[0018] In summary, this application includes at least one of the following beneficial technical effects: I. This invention involves inserting one side of the roller blind fabric with a positioning hole into the mounting groove on the mounting rod, and then inserting mounting heads at both ends of the mounting rod so that the mounting grooves on the two mounting heads correspond to the mounting grooves on the mounting rod. During the installation process on the mounting rod, the positioning protrusion in the limiting groove is squeezed and pushed to slide closer to the roller blind fabric, so that one side of the positioning protrusion is inserted into the positioning hole on the roller blind fabric. After the positioning protrusions at both ends of the mounting rod are inserted into the positioning holes, the mounting heads limit the positioning protrusions, and the positioning protrusions limit the roller blind fabric, thereby achieving rapid positioning and installation of the roller blind fabric.

[0019] II. This invention, when the movable mounting head is inserted into the limiting slide bar and the mounting rod, causes the elastic protrusion connected to the mounting head to be squeezed and contracted by the inner wall of the groove on the limiting slide bar. After the elastic protrusion is inserted into the groove, it elastically extends. At this time, the groove limits the elastic protrusion, thus achieving the effect of limiting and connecting the mounting head to the limiting slide bar and the mounting rod. When removal is required, the operator only needs to move the limiting slide bar or the mounting head to create a relative displacement between the limiting slide bar and the mounting head, which can quickly remove the mounting head from the limiting slide bar and the mounting rod, and at the same time release the limitation of the mounting head on the roller blind fabric, thereby facilitating the operator to quickly remove and replace the roller blind fabric.

[0020] Third, this invention increases the overall length of the roller by driving two bent sliding rods to slide away from each other. The movement of the bent sliding rods causes the connected extension rotating rod to move away from the mounting rod. The movement of the extension rotating rod causes the connected end cap, connecting protrusion, limiting protrusion, positioning protrusion, and sliding connecting rod to slide away from the mounting rod, thereby increasing the overall length of the roller. This allows workers to adjust and extend the roller according to the size of the window to be installed without removing the limiting frame and mounting bracket, so that workers can select a suitable roller blind to block the light from the window.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1To be continued Figure 12 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0036] This application discloses a roller blind and its assembly / disassembly assembly that are easy to install and remove. The roller blind and its assembly / disassembly assembly are mainly used in the process of installing and removing roller blinds from a wall, achieving the effect of quickly installing the roller blind on the wall. In particular, after the roller blind is installed on the wall, the roller blind fabric can be quickly and easily removed. Furthermore, when installing the roller blind fabric, the roller blind and its assembly / disassembly assembly can also adjust and extend the roller according to the size of the window to be installed, so that workers can select a suitable roller blind fabric to block light from the window.

[0037] Example 1: Refer to Figures 1 to 2 As shown, a roller blind that is easy to assemble and disassemble includes a mounting rod 1, a roller blind fabric 10, and a mounting head 11. The mounting rod 1 and the roller blind fabric 10 are connected by a limiting connection via the mounting head 11. After the mounting head 11 limits one side of the roller blind fabric 10 onto the mounting rod 1, the mounting head 11 and the mounting rod 1 cooperate to form a roller to limit the installation of the roller blind fabric 10. The roller blind fabric 10 can be rolled up and unrolled by rotating the mounting rod 1 and the mounting head 11. In use, after one end of the roller blind fabric 10 is placed against the mounting rod 1, the roller blind fabric 10 can be quickly limited and installed by the compression of the mounting head 11.

[0038] Reference Figures 1 to 3 As shown, a positioning hole 100 is provided on any side of the roller blind 10. The positioning holes 100 are preferably symmetrically provided at both ends of the same side of the roller blind 10, and at least two are provided to improve the stability of the roller blind 10 during installation. The mounting rod 1 and the mounting head 11 are jointly provided with a mounting groove 12 for inserting one end of the roller blind 10. A positioning protrusion 13 is symmetrically connected to the mounting head 11 and inserted into the positioning hole 100 to position and install the roller blind 10. The positioning protrusion 13 passes through the mounting rod 1. The mounting head 11 and the mounting rod 1 are detachably installed together by an elastic member 2.

[0039] In use, the side of the roller blind 10 with the positioning hole 100 is inserted into the mounting groove 12 on the mounting rod 1. Then, the mounting heads 11 are connected to both ends of the mounting rod 1, so that the mounting grooves 12 on the two mounting heads 11 correspond to the mounting grooves 12 on the mounting rod 1. During the installation process on the mounting rod 1, the positioning protrusion 13 in the limiting through groove 20 will be squeezed and pushed to slide closer to the roller blind 10, so that one side of the positioning protrusion 13 is inserted into the positioning hole 100 on the roller blind 10. After the positioning protrusions 13 at both ends of the mounting rod 1 are inserted into the positioning holes 100, and the two mounting heads 11 are connected to both ends of the mounting rod 1 through the elastic element 2, the positioning protrusion 13 is limited by the mounting head 11, and the positioning protrusion 13 limits the roller blind 10, thereby completing the positioning and installation effect of the roller blind 10.

[0040] Reference Figure 3 and Figure 4 As shown, the elastic element 2 is used to limit the installation between the mounting head 11 and the mounting rod 1. Specifically, the elastic element 2 includes a limiting groove 20, a limiting protrusion 21, an elastic protrusion 22, and a groove 23. The mounting rod 1 has symmetrical limiting grooves 20 at both ends that communicate with the mounting groove 12. The positioning protrusion 13 is slidably inserted into the limiting groove 20. The mounting head 11 is provided with a limiting protrusion 21 at a position corresponding to the limiting groove 20. The limiting protrusion 21 is connected to the elastic protrusion 22 inserted into the limiting groove 20. The groove 23 that is adapted to the elastic protrusion 22 is also connected in the limiting groove 20.

[0041] In use, when the movable mounting head 11 slides towards the mounting rod 1, the mounting head 11 drives the connected limiting protrusion 21 to be inserted into the limiting through groove 20 on the mounting rod 1. The movement of the limiting protrusion 21 drives the elastic protrusion 22 to be inserted into the limiting through groove 20 and abut against the inner wall of the limiting through groove 20. Due to the elastic abutment of the elastic protrusion 22, the limiting protrusion 21 slides towards the mounting groove 12 after being inserted into the limiting through groove 20, and pushes the same... The positioning protrusion 13 in the limiting groove 20 slides towards the mounting groove 12, so that the positioning protrusion 13 limits the roller blind 10. After the limiting protrusion 21 drives the elastic protrusion 22 to slide to the position of the groove 23, the telescopic section of the elastic protrusion 22 is inserted into the groove 23 to limit the continued sliding of the limiting protrusion 21, thereby achieving the limiting of the limiting protrusion 21 and the mounting head 11, and completing the effect of limiting the mounting head 11 to the mounting rod 1.

[0042] Furthermore, to improve the stability of the roller blind 10 after installation on the mounting rod 1, at least two limiting grooves 20 are provided at the same end of the mounting rod 1 and are arranged on both sides of the mounting groove 12. Correspondingly, multiple positioning protrusions 13 and limiting protrusions 21 are also provided corresponding to the limiting grooves 20. In the specific implementation process, after the mounting head 11 is installed on the mounting rod 1, the positioning protrusions 13 on both sides of the mounting groove 12 are simultaneously pressed and slid towards the middle of the mounting groove 12. After one side of the two positioning protrusions 13 abuts against each other and is inserted into the positioning hole 100, the roller blind 10 is limited to one side within the mounting groove 12, thereby improving the stability of the roller blind 10 after installation.

[0043] Reference Figures 3 to 5 As shown, the positioning protrusion 13 includes a driven slide 130 that is inserted into the limiting through groove 20. An extension protrusion 131, adapted to the positioning hole 100 on the roller blind 10, is connected to the side of the driven slide 130 near the mounting groove 12. The extension protrusion 131 extends through the limiting through groove 20 into the mounting groove 12 to limit the roller blind 10. In use, during the insertion of the limiting protrusion 21 into the limiting through groove 20, after the limiting protrusion 21 contacts the driven slide 130 in the limiting through groove 20, under the elastic drive of the connected elastic protrusion 22, it pushes the driven slide 130 and the extension protrusion 131 towards the central mounting groove 12, so that the extension protrusion 131 is inserted into the positioning hole 100 on the roller blind 10, thus limiting the roller blind 10.

[0044] Furthermore, to further increase the stability when installing the roller blind 10, the width of the limiting groove 20 is set to be slightly larger than the sum of the widths of the limiting protrusion 21 and the driven slide bar 130. To facilitate the sliding of the limiting protrusion 21 into the limiting groove 20, the side of the driven slide bar 130 away from the mounting groove 12 is sloped. In use, after the limiting protrusion 21 slides into the limiting groove 20, it pushes the driven slide bar 130 and the extending protrusion 131 along the slope towards the mounting groove 12.

[0045] Furthermore, referring to Figure 5 As shown, the driven slider 130 is also symmetrically connected to the guide slider 132 inserted on the mounting rod 1. The mounting rod 1 has a guide groove that communicates with the limiting through groove 20. The guide groove is set perpendicular to the mounting groove 12 to limit the connected driven slider 130 from always sliding along the guide groove aligned with the mounting groove 12. This avoids the shear stress generated when the roller is winding the curtain fabric 10, which causes the extension protrusion 131 to slip and cause the curtain fabric 10 to fall off accidentally.

[0046] Reference Figure 6As shown, the mounting head 11 includes a connecting protrusion 110 and a connecting end cap 111. The connecting protrusion 110 is inserted into the mounting rod 1. The end of the connecting protrusion 110 away from the mounting rod 1 is connected to the connecting end cap 111. The mounting groove 12 is opened on the connecting end cap 111. The limiting protrusion 21 is connected to the connecting end cap 111.

[0047] Reference Figures 2 to 6 As shown, the diameter of the connecting end cap 111 is set to correspond to the diameter of the mounting rod 1, so that when the mounting head 11 and the mounting rod 1 are driven to rotate to wind the roller blind 10, the roller blind 10 will always be in close contact with the outer side of the connecting mounting rod 1, and will not cause misalignment of the roller blind 10, thereby affecting the light blocking effect of the roller blind 10.

[0048] Reference Figures 2 to 6 As shown, a cover groove 112 is provided on the connecting end cover 111, and the connecting protrusion 110 is disposed in the cover groove 112. The cover groove 112 is connected to the mounting groove 12 on the connecting end cover 111. The cover groove 112 provided on the connecting end cover 111 is used to prevent the mounting head 11 from being excessively squeezed on the side of the roller blind 10 after it is connected to the mounting rod 1, which would cause the roller blind 10 to shift in position and thus affect the normal winding of the roller blind 10.

[0049] Reference Figures 2 to 6 As shown, the mounting groove 12 on the connecting end cover 111 is positioned closer to the mounting rod 1, and the mounting groove 12 and the cover groove 112 are arranged in a stepped manner. In use, since the mounting groove 12 and the cover groove 112 are arranged in a stepped manner, after the positions of the connecting end cover 111 and the mounting groove 12 on the mounting rod 1 are aligned, the two connecting end covers 111 at both ends of the mounting rod 1 are driven to slide towards each other. During the sliding process, the two connecting end covers 111 contact the side of the roller blind 10, and the side of the roller blind 10 is inserted into the mounting groove 12 on the connecting end cover 111. As the two connecting end covers 111 gradually approach each other, the position of the roller blind 10 is gradually driven to the middle of the mounting rod 1. After both connecting end covers 111 are in contact with the mounting rod 1, the mounting head 11 is assembled onto the mounting rod 1, and the position of the roller blind 10 is also positioned and limited, thereby improving the efficiency of assembling and disassembling the roller blind 10.

[0050] Reference Figure 7 and Figure 8 As shown, a disassembly and assembly assembly includes a connecting part 3 that mates with an mounting head 11. The connecting part 3 is mounted on a wall for assembling the mounting head 11 and the mounting rod 1.

[0051] Reference Figure 7 and Figure 8As shown, the connecting part 3 includes an extension rotating rod 30, a limiting frame 31, and mounting brackets 32. The side of the mounting head 11 away from the mounting rod 1 is connected to the extension rotating rod 30. The limiting frame 31 with a U-shaped structure is rotatably mounted on the extension rotating rod 30. At least two mounting brackets 32 are symmetrically connected to the middle of the limiting frame 31. The mounting brackets 32 have through holes for bolts to pass through and fix them. In use, the mounting brackets 32 and the limiting frame 31 are fixed to the wall with bolts to complete the fixed installation of the connecting part 3. Then, the mounting head 11, the mounting rod 1, and the roller blind 10 are assembled to achieve the limiting installation effect of the roller blind 10. When it is necessary to drive the roller to rotate, the operator only needs to drive either of the extension rods 30 at both ends of the roller to rotate, which will drive the roller to rotate synchronously. Of course, an existing motor device can also be directly connected to the extension rod 30 on the limit frame 31 to drive the extension rod 30 and the roller to rotate, thereby achieving the automatic winding and unwinding effect of the roller curtain 10.

[0052] Since the limiting frame 31 and the extension rod 30 are rotatably connected, as an optional implementation, the limiting frame 31 and the mounting bracket 32 ​​are fitted together on a vertical wall. At this time, the two vertical sections of the limiting frame 31 are parallel to the ground. The gap between the roller blind 10 and the window depends on the thickness of the horizontal section of the limiting frame 31 and the gap between the limiting frame 31 and the wall. In this installation method, the gap between the roller blind 10 and the window is relatively large, which is suitable for applications where the light-blocking requirements are not high.

[0053] In another implementation, the limiting frame 31 and the mounting bracket 32 ​​are attached to the ceiling. At this time, the two vertical sections of the limiting frame 31 are perpendicular to the ground. The gap between the roller blind 10 and the window depends on the installation position of the limiting frame 31. The gap between the roller blind 10 and the window is small, which is suitable for applications with high light-blocking requirements.

[0054] By using two different installation methods, different gaps can be achieved between the roller blind 10 and the window after installation, thus adapting to different light-blocking needs and improving the practicality and applicability of this curtain.

[0055] Example 2: Refer to Figures 7 to 8As shown, based on Embodiment 1, in order to improve the applicability of this curtain and to select different sizes of roller blind fabric 10 according to different window specifications, an adjusting component 4 is provided to adaptively extend the length of the mounting rod 1. Specifically, the adjusting component 4 includes a limiting guide block 40 and a sliding connecting rod 41. A through groove is formed in the middle of the mounting rod 1, and a limiting guide block 40 connected to the mounting rod 1 is provided in the middle of the through groove. At least two sliding connecting rods 41 are symmetrically slidably inserted into the mounting rod 1. The sliding connecting rods 41 and the mounting rod 1 are connected by a spline engagement. The two sliding connecting rods are arranged on both sides of the limiting guide block 40. A connection is also provided on the sliding connecting rod 41 and the limiting guide block 40 to the mounting rod 1. Correspondingly, the mounting groove 12, at this time, the limiting through groove 20 and the groove 23 are respectively opened on the sliding connecting rod 41, the connecting protrusion 110 is slidably inserted on the sliding connecting rod 41, the inner diameter of the cover groove 112 is set to correspond to the outer diameter of the sliding connecting rod 41, and the mutual cooperation between the mounting rod 1, the two sliding connecting rods 41 and the mounting head 11 forms a roller to wind up and release the curtain fabric 10; at the same time, the limiting frame 31 also includes a horizontal sleeve 310 and two bent sliding rods 311 symmetrically slidably inserted in the horizontal sleeve 310, the extension rotating rod 30 is rotatably inserted on the bent sliding rods 311, and a driving end 42 for driving the bent sliding rods 311 to adjust their position is connected on the horizontal sleeve 310.

[0056] In use, the two bent slide rods 311 are driven by the drive end 42 to slide away from each other. The movement of the bent slide rods 311 causes the connected extension rotating rod 30 to move away from the mounting rod 1. The movement of the extension rotating rod 30 causes the connected connecting end cap 111, connecting protrusion 110, limiting protrusion 21, positioning protrusion 13 and sliding connecting rod 41 to slide away from the mounting rod 1, so as to increase the overall length of the roll.

[0057] Furthermore, in this embodiment, the sum of the lengths of the two sliding links 41 is not greater than the length of the mounting rod 1, so that both sliding links 41 are retracted within the mounting rod 1, thereby adapting to windows of different sizes.

[0058] As an alternative implementation, the length of the sliding link 41 can also be set to be at least not less than the length of the mounting rod 1, thus allowing its application to larger windows.

[0059] Reference Figures 8 to 12As shown, the drive end 42 is used to drive the bending slide bar 311 for position adjustment. Specifically, the drive end 42 includes an adjusting spring 420, a rotating wheel rod 421, a driven gear 422, and a driven toothed plate 423. The adjusting spring 420 is connected between the opposite ends of the sliding link 41 and the limiting guide block 40. In the initial state, the adjusting spring 420 is in a compressed state to provide the connected sliding link 41 with a driving force that always protrudes outward along the through groove of the mounting rod 1, and the two sliding links 41 are either retracted inside the mounting rod 1 or only protruding outward by a certain distance.

[0060] In order to limit the extent of the sliding connecting rod 41 protruding outward from the mounting rod 1 along the through groove, a sliding cavity is formed between the horizontal sleeve 310 and the two bent sliding rods 311. A rotating wheel rod 421 is rotatably connected to the middle of the sliding cavity. A driven gear 422 is sleeved on the rotating wheel rod 421. Two driven toothed plates 423 mesh on the outer side of the driven gear 422. The two driven toothed plates 423 are distributed vertically on both sides of the driven gear 422 and are correspondingly connected to the two bent sliding rods 311.

[0061] In use, the axial driving force of the two adjusting springs 420 drives the connected sliding connecting rods 41 to slide out of the mounting rod 1, causing the two sliding connecting rods 41 to slide away from each other. The movement of the sliding connecting rods 41 drives the connected mounting head 11 and the bent sliding rod 311 to slide synchronously. The movement of the bent sliding rod 311 drives the connected driven tooth plate 423 to move horizontally. The movement of the driven tooth plate 423 drives the driven gear 422 meshing with it to rotate, thereby driving the bent sliding rod 311 to slide and extend along the horizontal sleeve 310, and adjusting and limiting the position of the connected sliding connecting rods 41.

[0062] Furthermore, referring to Figure 9 and Figure 11 As shown, in order to limit and fix the position of the sliding linkage 41 after sliding adjustment so that the operator can install the appropriate size roller blind 10 according to the window size, the rotating wheel rod 421 and the driven gear 422 are configured with a spline fit. A limiting slide rod 43 is symmetrically and slidably inserted on the horizontal sleeve 310 to limit the spline on the rotating wheel rod 421. A sloping block 430 with an inclined surface structure is provided on the side of the limiting slide rod 43 near the driven gear 422. The flat sleeve 310 is symmetrically provided with sliding grooves that are adapted to the limiting slide rod 43 at the corresponding positions. The sliding grooves only allow the connected limiting slide rod 43 to slide horizontally. A bending slider 431 is also slidably connected to the horizontal sleeve 310. A contraction spring 432 is connected between the horizontal section of the bending slider 431 and the horizontal sleeve 310. Furthermore, the end of the limiting slide rod 43 near the bending slider 431 is set as a slope so that the bending slider 431 can abut against it.

[0063] In the specific implementation process, by moving the bending slider 431 away from the horizontal sleeve 310, the bending slider 431 moves and stretches the connected contraction spring 432. At this time, under the drive of the adjusting spring 420, the driven gear 422 and the rotating wheel rod 421 are driven to rotate. After the rotating wheel rod 421 rotates, it pushes the inclined block 430 and the limiting slide rod 43 along the inclined block 430 on the limiting slide rod 43 to slide away from the rotating wheel rod 421 until the limiting slide rod 43 moves to the end of the sliding groove away from the rotating wheel rod 421. At this time, the slope on the limiting slide rod 43 abuts against the vertical section of the bending slider 431, and the driven gear 422 and the rotating wheel rod 421 can rotate normally so as to adjust the relative position of the mounting rod 1 and the sliding connecting rod 41.

[0064] When the driving force of the bending slider 431 is released, under the drive of the retraction spring 432, the bending slider 431 is driven to slide and reset towards the horizontal sleeve 310. The bending slider 431 moves along the slope of the abutting limiting slide rod 43, driving the limiting slide rod 43 to slide towards the rotating wheel rod 421. After the limiting slide rod 43 and the inclined block 430 move to abut against the outer surface of one of the splines on the rotating wheel rod 421, the retraction spring 432... Driven by the movement, the vertical section of the bending slider 431 completely crosses the slope on the limiting slider 43 until one end of the slope of the limiting slider 43 touches the horizontal section of the bending slider 431. At this time, the horizontal and vertical sections of the bending slider 431 simultaneously limit the limiting slider 43, thereby restricting the rotation of the rotating wheel rod 421 and the driven gear 422 from continuing to rotate. This achieves the effect of limiting and fixing the position of the sliding linkage 41 and the bending slider 311 after the sliding adjustment.

[0065] It should be noted that although the rotation of the rotating wheel rod 421 and the driven gear 422 can be restricted to continue rotating in the forward direction by the limiting slide rod 43 and the wedge block 430 abutting against the spline on the rotating wheel rod 421, the rotating wheel rod 421 and the driven gear 422 can still rotate in the reverse direction to a certain extent (the extent depends on the distance between two adjacent splines on the rotating wheel rod 421) because the wedge block 430 only abuts against one side of one of the splines on the rotating wheel rod 421.

[0066] Based on this, when the rotating wheel 421 is driven to rotate to adjust and extend the position of the bending slide 311 and the limiting slide 43, the rotating wheel 421 rotates a certain amount (that is, the interval between two adjacent splines), causing the limiting slide 43 to extend outward a certain distance along the mounting rod 1. Then, the limiting slide 43 and the inclined block 430 limit the spline that has rotated more. At this time, the limiting slide 43 and the mounting rod 1, as well as the bending slide 311 and the horizontal sleeve 310, are all in a state that allows for a certain degree of telescopic sliding. The overall length of the roller is slightly longer than the length of the roller blind 10. Under the reset drive of the two adjusting springs 420, the connected limiting slide 43 always tends to protrude outward from the mounting rod 1, so as to elastically tension the roller blind 10 on the roller, so that the roller blind 10 on the roller is completely attached to the outer surface of the roller.

[0067] When workers need to remove the roller blind 10 from the roller, they first need to completely release the roller blind 10 wound on the roller. Then, the workers drive the two limiting slide rods 43 to slide towards each other. At this time, the mounting head 11 inserted at the end of the limiting slide rod 43 is limited by the bent slide rod 311. When relative displacement occurs between the limiting slide rod 43 and the connected mounting head 11, the limiting protrusion 21 gradually disengages from the groove 23 on the limiting slide rod 43, completing the separation of the limiting slide rod 43 and the mounting head 11. This releases the limitation of the mounting head 11 on the roller blind 10, so that workers can remove the roller blind 10 for replacement.

[0068] Reference Figure 11 and Figure 12As shown, at least two limit seats 44 with a U-shaped structure are symmetrically connected to the horizontal sleeve 310. A connecting slider 440 is slidably inserted on the limit seat 44. A clamping spring 441 is connected between the connecting slider 440 and the limit seat 44. A limit ring 442 is connected to the side of the connecting slider 440 away from the clamping spring 441. The limit ring 442 is slidably connected to the limit seat 44. The clamping roller 443 rotates together between the two limit rings 442. In use, the roller blind 10 wound on the roller shaft squeezes the clamping roller 443, causing the clamping roller 443 to slide away from the roller shaft. The movement of the clamping roller 443 drives the limiting rings 442 and connecting sliders 440 at both ends to slide closer to the horizontal sleeve 310, and compresses the connected clamping spring 441. The elastic restoring force of the compressed clamping spring 441 causes the connecting slider 440, the limiting rings 442 and the clamping roller 440 to slide closer to the horizontal sleeve 310. Roller 443 always tends to slide towards the roller shaft, causing the clamping roller 443 to float against the outer surface of the roller blind 10. In normal use, the side of the roller blind 10 away from the roller shaft is usually equipped with a hem to increase the weight of the lower side of the roller blind 10, so that the roller blind 10 remains in a natural hanging state when it is rolled up and released, thereby helping the roller blind 10 to be rolled up or unrolled evenly, and preventing the roller blind 10 from knotting or wrinkling when it is rolled up.

[0069] During operation: First, install the limiting frame 31, mounting bracket 32 ​​and mounting head 11 on the wall corresponding to the window. Then, insert the end of the roller blind 10 with the positioning hole 100 into the mounting rod 1. Next, assemble the mounting rod 1 and mounting head 11 to form a roller to wind the roller blind 10.

[0070] Step 2: During the process of assembling the two mounting heads 11 at both ends of the mounting rod 1, the elastic element 2 connected to the mounting head 11 is used to further limit the roller blind 10. After the assembly of the mounting head 11 and the mounting rod 1 is completed, the roller blind 10 is also simultaneously limited and installed on the roller.

[0071] Step 3: When removal is required, simply drive the mounting heads 11 at both ends of the mounting rod 1 to separate it, and the roller blind 10 can be quickly released from its limit so that the staff can remove and replace the roller blind 10.
