Description

Technical Field

[0001] The invention relates to the field of roller curtains, and in particular to a roller curtain that is easy to disassemble and assemble and a disassembly assembly component. Background Art

[0002] In modern interior decoration and functional requirements, curtains are an important shading and decorative element, and their convenience, beauty and functionality are increasingly valued by people. The installation and removal process of traditional curtains is often complicated and time-consuming, especially when the curtain fabric needs to be cleaned or replaced. Roller curtains have been widely used in offices, homes and other environments due to their simple structure and convenient operation.

[0003] However, ordinary roller curtains usually have some problems in daily use. With the development of science and technology, technicians in related fields have also made a lot of optimizations on roller curtains. In order to make a more accurate comparison, for example, the Chinese patent with publication number CN118390948A discloses auxiliary mounting parts, mounting components and shading devices for standard-sized roller curtains, including a connecting part and at least one mounting part, wherein the connecting part is located at the end, the connecting part is connected to the roller curtain mounting bracket, and the mounting part is connected to the window frame, etc. When in use, the curtain assembly is installed by the mutual cooperation of the connecting part, the mounting part and the auxiliary mounting part, and the adaptation problem of the curtain assembly and the window frame width is solved by adjusting the relative positions among the connecting part, the mounting part and the auxiliary mounting part.

[0004] However, the above device still has some shortcomings in actual use:

[0005] 1. The above device completes the installation of the curtain assembly by positioning the curtain assembly between the first bracket and the second bracket, and overlapping the first auxiliary mounting member connecting portion and the second auxiliary mounting member connecting portion with the auxiliary mounting member respectively, and tightening and fixing the curtain assembly by threading a plurality of screws. When the position of the curtain assembly needs to be adjusted accordingly according to the width of the window frame, the staff needs to climb to a high place to remove the tightened screws one by one, adjust the relative position between the first bracket and the second bracket according to the width of the window frame, and then tighten the screws again. It is relatively time-consuming and laborious to adjust the position of the curtain assembly.

[0006] 2. Since the curtain assembly of the above device is directly connected to the curtain cloth through the reel, when the curtain cloth needs to be disassembled and replaced, the reel and the curtain cloth need to be removed from the window frame at the same time, and the two ends of the reel are respectively limited by the first bracket and the second bracket. Therefore, when the curtain cloth needs to be removed, the first bracket and the second bracket need to be removed from the auxiliary mounting member simultaneously, which is time-consuming and labor-intensive.

[0007] Therefore, under the above-stated viewpoint, the existing roller blinds still have room for improvement. Summary of the invention

[0008] In order to solve the above problems, the present invention provides a roller curtain that is easy to disassemble and assemble, including a mounting rod and a rolling curtain cloth. The mounting rod and the rolling curtain cloth are connected by a mounting head. After the mounting head limits one side of the rolling curtain cloth on the mounting rod, the mounting head and the mounting rod cooperate with each other to form a winding shaft to limit the installation of the rolling curtain cloth. The effect of winding and loosening the rolling curtain cloth is achieved by rotating the mounting rod and the mounting head.

[0009] A positioning hole is provided on either side of the rolling blind cloth, and a mounting groove is formed together with the mounting rod and the mounting head for inserting one end of the rolling blind cloth. A positioning protrusion is symmetrically connected to the mounting head and is inserted into the positioning hole to position and install the rolling blind cloth. The positioning protrusion is passed through the mounting rod, and the mounting head and the mounting rod are detachably mounted together through an elastic member.

[0010] Preferably, the elastic member includes limiting grooves symmetrically opened at both ends of the mounting rod and connected to the mounting groove, the positioning protrusion is limitedly inserted in the limiting groove, a limiting protrusion is arranged on the mounting head corresponding to the position of the limiting groove, the limiting protrusion is connected to an elastic convex contact inserted in the limiting groove, and a groove adapted to the elastic convex contact is also connected in the limiting groove.

[0011] Preferably, the positioning protrusion includes a driven slide bar inserted in the limiting groove, and the side of the driven slide bar close to the mounting groove is connected to an extension protrusion bar that is compatible with the positioning hole on the rolling curtain cloth. The extension protrusion bar passes through the limiting groove and extends into the mounting groove to limit the rolling curtain cloth.

[0012] Preferably, the driven slide bar is also symmetrically connected to a guide slide block inserted on the mounting rod to limit the sliding path of the connected driven slide bar.

[0013] Preferably, the mounting head comprises a connecting protrusion inserted on the mounting rod, an end of the connecting protrusion away from the mounting rod is connected to a connecting end cover, a mounting groove is provided on the connecting end cover, and the limiting protrusion is connected to the connecting end cover.

[0014] Preferably, the diameter of the connecting end cover and the diameter of the mounting rod are set correspondingly.

[0015] Preferably, a covering groove is provided on the connecting end cover, the connecting protruding rod is arranged in the covering groove, and the covering groove and the mounting groove on the connecting end cover are connected to each other.

[0016] Preferably, the mounting groove on the connecting end cover is arranged toward a side close to the mounting rod, and the mounting groove and the covering groove are arranged in a stepped manner up and down.

[0017] In addition, the present invention also provides a disassembly and assembly component, including a connecting portion that cooperates with the installation head, and the connecting portion is installed on the wall to allow the installation head and the installation rod to be assembled and combined.

[0018] Preferably, the connecting portion comprises an extending rotating rod connected to one side of the mounting head away from the mounting rod, and a limiting frame having a U-shaped structure is sleeved on the extending rotating rod.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The present invention inserts one side of the positioning hole on the rolling blind cloth into the mounting groove on the mounting rod, and then inserts 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 on the mounting rod, the positioning protrusion in the limiting through groove is squeezed and pushed to slide in the direction close to the rolling blind cloth, so that one side of the positioning protrusion is inserted into the positioning hole on the rolling blind cloth. After the positioning protrusions at both ends of the mounting rod are inserted into the positioning holes, the positioning protrusion is limited by the mounting head, and the rolling blind cloth is limited by the positioning protrusion, thereby completing the rapid positioning and installation effect of the rolling blind cloth.

[0021] 2. The present invention enables the elastic convex contact connected to the mounting head to be squeezed and contracted by the inner wall of the groove on the limiting slide bar when the movable mounting head is inserted on the limiting slide bar and the mounting rod. After the elastic convex contact is inserted in the groove, the elastic convex contact elastically stretches. At this time, the elastic convex contact is limited by the groove, and the mounting head is connected to the limiting slide bar and the mounting rod. When removal is required, the staff only needs to move the limiting slide bar or the mounting head to generate a relative displacement between the limiting slide bar and the mounting head, and the mounting head can be quickly removed from the limiting slide bar and the mounting rod, and the limitation of the roller blind cloth by the mounting head can be released at the same time, thereby facilitating the staff to quickly remove and replace the roller blind cloth.

[0022] 3. The present invention drives the two bent slide bars to slide in the direction away from each other, and the movement of the bent slide bars drives the connected extending rotating bars to move in the direction away from the mounting rod, and the movement of the extending rotating rod drives the connected connecting end caps, connecting protruding rods, limiting protruding rods, positioning protruding rods and sliding connecting rods to slide in the direction away from the mounting rod, so as to increase the overall length of the reel, so that the staff can adjust and extend the reel accordingly according to the size of the window to be installed without removing the limiting frame and the mounting code, so that the staff can select appropriate roller blinds to shade the window.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 To Attachment Fig.12 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0038] The embodiment of the present application discloses a roller curtain and a disassembly assembly component that are easy to disassemble and assemble. It is explained that the roller curtain and the disassembly assembly component are mainly used in the process of loading and unloading the roller curtain on the wall, and the technical effect is to achieve the effect of quickly installing the roller curtain on the wall; in particular, after the roller curtain is installed on the wall, the roller curtain cloth therein can be quickly and conveniently removed; further, when installing the roller curtain cloth, the roller curtain and the disassembly assembly can also adjust and extend the size of the roller accordingly according to the size of the window to be installed, so that the staff can select a suitable roller curtain cloth to shade the window.

[0039] Example 1: Reference Figure 1 to Figure 2 As shown, a roller curtain that is easy to disassemble and assemble includes a mounting rod 1, a rolling curtain 10 and a mounting head 11. The mounting rod 1 and the rolling curtain 10 are connected by the mounting head 11. After the mounting head 11 positions one side of the rolling curtain 10 on the mounting rod 1, the mounting head 11 and the mounting rod 1 cooperate with each other to form a reel to positionally install the rolling curtain 10. The rolling curtain 10 can be wound and unwound by rotating the mounting rod 1 and the mounting head 11. When in use, after one end of the rolling curtain 10 is placed against the mounting rod 1, the rolling curtain 10 can be quickly installed by squeezing and positioning the rolling curtain 10 by the mounting head 11.

[0040] Reference Figures 1 to 3 As shown, a positioning hole 100 is provided on either side of the rolling blind fabric 10. The positioning holes 100 are preferably symmetrically provided at both ends of the same side of the rolling blind fabric 10, and at least two of them are provided to improve the stability of the rolling blind fabric 10 during installation. A mounting groove 12 for inserting one end of the rolling blind fabric 10 is formed on the mounting rod 1 and the mounting head 11. A positioning protrusion 13 is symmetrically connected to the mounting head 11 and is inserted into the positioning hole 100 to position and install the rolling blind fabric 10. The positioning protrusion 13 is passed through the mounting rod 1, and the mounting head 11 and the mounting rod 1 are detachably mounted together via an elastic member 2.

[0041] When in use, one side of the positioning hole 100 opened on the rolling curtain cloth 10 is inserted into the mounting groove 12 on the mounting rod 1, and then the mounting heads 11 are connected to the two 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 in the direction close to the rolling curtain cloth 10, so that one side of the positioning protrusion 13 is inserted into the positioning hole 100 on the rolling curtain cloth 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 the two ends of the mounting rod 1 through the elastic member 2, the positioning protrusion 13 is limited by the mounting head 11, and the positioning protrusion 13 limits the rolling curtain cloth 10, thereby completing the positioning and installation effect of the rolling curtain cloth 10.

[0042] Reference Figure 3 and Figure 4 As shown, an elastic member 2 is used for limiting the installation between the installation head 11 and the installation rod 1; specifically, the elastic member 2 includes a limiting through groove 20, a limiting convex rod 21, an elastic convex contact 22 and a groove 23. The two ends of the installation rod 1 are symmetrically provided with limiting through grooves 20 connected to the installation grooves 12, and the positioning convex rod 13 is slidably inserted in the limiting through grooves 20. A limiting convex rod 21 is provided on the installation head 11 corresponding to the position of the limiting through groove 20. The limiting convex rod 21 is connected to an elastic convex contact 22 inserted in the limiting through groove 20, and a groove 23 adapted to the elastic convex contact 22 is also connected in the limiting through groove 20.

[0043] When in use, when the mobile mounting head 11 slides toward the direction close to the mounting rod 1, the mounting head 11 drives the connected limiting convex rod 21 to be inserted into the limiting groove 20 on the mounting rod 1, and the limiting convex rod 21 moves to drive the elastic convex contact 22 to be inserted into the limiting groove 20 and abut against the inner side wall of the limiting groove 20. Due to the elastic abutment of the elastic convex contact 22, the limiting convex rod 21 is inserted into the limiting groove 20 and then slides toward the direction close to the mounting groove 12, and pushes the same The positioning protrusion 13 in a limiting through groove 20 slides toward the direction close to the mounting groove 12, so that the positioning protrusion 13 limits the rolling curtain 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 in 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 be installed on the mounting rod 1.

[0044] Furthermore, in order to improve the stability of the roller blind 10 after being installed 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, the positioning protrusions 13 and the limiting protrusions 21 are also provided in a plurality corresponding to the limiting grooves 20. In the specific implementation process, after the mounting head 11 is mounted on the mounting rod 1, the positioning protrusions 13 on both sides of the mounting groove 12 are squeezed to slide in the direction close to the middle mounting groove 12. After one side of the two positioning protrusions 13 contacts each other and is inserted into the positioning hole 100, the effect of limiting one side of the roller blind 10 in the mounting groove 12 is completed, thereby improving the stability of the roller blind 10 after installation.

[0045] Reference Figures 3 to 5 As shown, the positioning convex rod 13 includes a driven slide bar 130 inserted into the limiting slot 20, and an extension convex rod 131 matched with the positioning hole 100 on the rolling curtain 10 is connected to the side of the driven slide bar 130 close to the mounting slot 12. The extension convex rod 131 passes through the limiting slot 20 and extends into the mounting slot 12 to limit the rolling curtain 10. When in use, when the limiting convex rod 21 is inserted into the limiting slot 20, after the limiting convex rod 21 contacts the driven slide bar 130 in the limiting slot 20, the elastic drive of the connected elastic convex contact 22 pushes the driven slide bar 130 and the extension convex rod 131 to slide in the direction close to the middle mounting slot 12, so that the extension convex rod 131 is inserted into the positioning hole 100 on the rolling curtain 10 to limit the rolling curtain 10.

[0046] Furthermore, in order to further increase the stability when installing the rolling blind 10, the width of the limiting slot 20 is set to be slightly larger than the sum of the widths of the limiting convex rod 21 and the driven slide bar 130, and in order to facilitate the limiting convex rod 21 to slide into the limiting slot 20, the side of the driven slide bar 130 away from the installation slot 12 is set to be a slope. When in use, after the limiting convex rod 21 slides into the limiting slot 20, the driven slide bar 130 and the extension convex rod 131 are pushed along the slope on the driven slide bar 130 to slide in the direction close to the installation slot 12.

[0047] Going a step further, refer to Figure 5 As shown, the driven slide 130 is also symmetrically connected to a guide slider 132 inserted on the mounting rod 1, and a guide slide groove connected to the limiting through groove 20 is opened on the mounting rod 1. The guide slide groove is arranged perpendicular to the mounting groove 12 to limit the connected driven slide 130 to always slide along the guide slide groove to align with the mounting groove 12, thereby avoiding the shear stress generated when the reel winds the rolling curtain 10 and causing the extended protrusion 131 to slip in position, causing the rolling curtain 10 to accidentally fall off.

[0048] Reference Figure 6As shown, the mounting head 11 includes a connecting protrusion 110 and a connecting end cover 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 cover 111. The mounting groove 12 is opened on the connecting end cover 111, and the limiting protrusion 21 is connected to the connecting end cover 111.

[0049] Reference Figures 2 to 6 As shown, the diameter of the connecting end cover 111 and the diameter of the mounting rod 1 are set correspondingly, so that when the mounting head 11 and the mounting rod 1 are driven to rotate to wind the rolling blind 10, the rolling blind 10 is always tightly attached to the outer side surface of the connecting mounting rod 1, and will not cause the rolling blind 10 to be misaligned, thereby affecting the shading effect of the rolling blind 10.

[0050] Reference Figures 2 to 6 As shown, a covering groove 112 is provided on the connecting end cover 111, and the connecting protruding rod 110 is arranged in the covering groove 112. The covering groove 112 and the mounting groove 12 on the connecting end cover 111 are connected to each other. The covering groove 112 on the connecting end cover 111 is used to prevent the mounting head 11 from excessively squeezing the side of the rolling curtain 10 after being connected to the mounting rod 1, driving the rolling curtain 10 to shift in position, thereby affecting the normal winding of the rolling curtain 10.

[0051] Reference Figures 2 to 6 As shown, the mounting groove 12 on the connecting end cap 111 is arranged close to the mounting rod 1, and the mounting groove 12 and the covering groove 112 are arranged in a stepped manner. When in use, since the mounting groove 12 and the covering groove 112 are arranged in a stepped manner, after the connecting end cap 111 and the mounting groove 12 on the mounting rod 1 are aligned, the two connecting end caps 111 at both ends of the mounting rod 1 are driven to slide in a direction close to each other, and the two connecting end caps 111 contact the side of the rolling curtain 10 during the sliding process, and the side of the rolling curtain 10 is inserted into the mounting groove 12 on the connecting end cap 111. As the two connecting end caps 111 gradually approach, the position of the rolling curtain 10 is gradually driven to be located in the middle of the mounting rod 1. After both connecting end caps 111 contact the mounting rod 1, the mounting head 11 is assembled on the mounting rod 1, and the positioning and limiting effect of the position of the rolling curtain 10 is also completed, thereby improving the efficiency of disassembling and assembling the rolling curtain 10.

[0052] Reference Figure 7 and Figure 8 As shown, a disassembly assembly component includes a connecting portion 3 that cooperates with the mounting head 11. The connecting portion 3 is installed on the wall for the mounting head 11 and the mounting rod 1 to be assembled and combined.

[0053] Reference Figure 7 and Figure 8As shown, the connection part 3 includes an extension rod 30, a limit frame 31 and a mounting bracket 32. The side of the mounting head 11 away from the mounting rod 1 is connected to the extension rod 30. The limit frame 31 with a U-shaped structure is rotated on the extension rod 30. The middle part of the limit frame 31 is symmetrically connected to at least two mounting brackets 32. The mounting brackets 32 are provided with through holes for bolts to pass through and fix. When in use, the mounting brackets 32 and the limit frame 31 are fixed to the wall by bolts, that is, the fixed installation of the connection part 3 is completed, and then the mounting head 11, the mounting rod 1 and the rolling curtain 10 are assembled and combined to complete the limited installation effect of the rolling curtain 10. When it is necessary to drive the reel to rotate, the staff only needs to drive any one of the extension rotating rods 30 at both ends of the reel to rotate, so as to achieve the effect of driving the reel to rotate synchronously. Of course, the existing motor equipment can also be directly connected to the extension rotating rod 30 on the limit frame 31 to drive the extension rotating rod 30 and the reel to rotate, thereby achieving the automatic winding and releasing effect of the roller curtain 10.

[0054] Since the limit frame 31 and the extending rotating rod 30 are rotatably connected, as an optional implementation method, the limit frame 31 and the mounting code 32 are installed on the vertical wall. At this time, the two vertical sections of the limit frame 31 are parallel to the ground, and the gap between the roller blind 10 and the window depends on the thickness of the horizontal section of the limit frame 31 and the gap between the limit frame 31 and the wall. Under this installation method, the gap between the roller blind 10 and the window is relatively large, which is suitable for use with low requirements for shading.

[0055] As another embodiment, the limit frame 31 and the mounting code 32 are fitted on the ceiling. At this time, the two vertical sections of the limit frame 31 are perpendicular to the ground. The gap between the roller blind 10 and the window depends on the installation position of the limit frame 31. The gap between the roller blind 10 and the window is small, which is suitable for use with high requirements for shading.

[0056] Through two different installation methods, different gaps between the roller blind 10 and the window can be achieved after installation, so as to be suitable for situations with different shading requirements, thereby improving the practicality and applicability of the curtain when in use.

[0057] Example 2: Reference Figures 7 to 8As shown, on the basis of the first embodiment, in order to improve the applicability of the curtain when applied, in order to select roller blinds 10 of different sizes according to different window specifications, an adjusting member 4 for adaptively extending the length of the mounting rod 1 is provided. Specifically, the adjusting member 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 in the mounting rod 1. The sliding connecting rod 41 and the mounting rod 1 are connected by spline matching. The two sliding connections are arranged on both sides of the limiting guide block 40. The sliding connecting rod 41 and the limiting guide block 40 are also provided with a spline connection connected to the mounting rod 1. Corresponding to the mounting groove 12, at this time, the limiting through groove 20 and the groove 23 are correspondingly opened on the sliding link 41, the connecting protruding rod 110 is slidably inserted on the sliding link 41, the inner diameter of the covering groove 112 is set corresponding to the outer diameter of the sliding link 41, and the mutual cooperation between the mounting rod 1, the two sliding links 41 and the mounting head 11 forms a reel to roll up and release the rolling curtain 10; at the same time, the limiting frame 31 also correspondingly includes a horizontal sleeve 310 and two bent slides 311 symmetrically slidably inserted in the horizontal sleeve 310, the extension rotating rod 30 is rotatably inserted on the bent slide 311, and the horizontal sleeve 310 is connected with a driving end 42 for driving the bent slide 311 to adjust the position.

[0058] When in use, the driving end 42 drives the two bent slide rods 311 to slide away from each other, and the movement of the bent slide rod 311 drives the connected extension rotating rod 30 to move away from the mounting rod 1. The movement of the extension rotating rod 30 drives the connected connecting end cover 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 achieve the effect of increasing the overall length of the reel.

[0059] 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 the two sliding links 41 are both retracted in the mounting rod 1 , thereby adapting to windows of different sizes.

[0060] As an optional embodiment, the length of the sliding link 41 may also be set to be at least not less than the length of the mounting rod 1, so as to be applied to windows of larger sizes.

[0061] Reference Figures 8 to 12As shown, the driving end 42 is used to drive the bending slide rod 311 to adjust the position; specifically, the driving end 42 includes an adjusting spring 420, a rotating wheel rod 421, a driven gear 422 and a driven gear plate 423, and an adjusting spring 420 is commonly connected between the opposite ends of the sliding link 41 and the limiting guide block 40. The adjusting spring 420 is in a compressed state under force in the initial state to provide the connected sliding link 41 with a driving force that always protrudes outward along the through groove to the mounting rod 1, and the two sliding links 41 are in a state of being retracted in the mounting rod 1 or only protruding outward for a certain section.

[0062] In order to limit the extent to which the sliding connecting rod 41 protrudes 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 tooth plates 423 are meshed on the outer side of the driven gear 422. The two driven tooth plates 423 are distributed up and down on both sides of the driven gear 422 and are correspondingly connected to the two bent sliding rods 311.

[0063] When in use, the axial driving force of the two adjusting springs 420 is used to drive the connected sliding link 41 to slide in the direction of sliding out of the mounting rod 1, so that the two sliding links 41 slide in the direction away from each other, and the movement of the sliding link 41 drives the connected mounting head 11 and the bending slide bar 311 to slide synchronously, and the movement of the bending slide bar 311 drives the connected driven tooth plate 423 to move in the horizontal direction, and the movement of the driven tooth plate 423 drives the driven gear 422 meshing with it to rotate, thereby driving the bending slide bar 311 to slide and extend along the horizontal sleeve 310, and adjusting and limiting the position of the connected sliding link 41.

[0064] Further, refer to Fig. 9 and Fig.11 As shown, in order to limit and fix the position of the sliding link 41 after the sliding adjustment so that the staff can install the roller blind 10 of the appropriate size according to the size of the window, a spline matching structure is set between the rotating wheel rod 421 and the driven gear 422, and a limiting slide rod 43 for limiting the spline on the rotating wheel rod 421 is symmetrically and slidably inserted on the horizontal sleeve 310, and a bevel block 430 of a bevel structure is set on the side of the limiting slide rod 43 close to the driven gear 422. The flat sleeve 310 is symmetrically provided with sliding grooves that are compatible with the limiting slide bar 43 at the position corresponding to the limiting slide bar 43. The sliding grooves only allow the connected limiting slide bar 43 to slide in the horizontal direction. A bending slide bar 431 is also slidably connected to the horizontal sleeve 310. A contraction spring 432 is connected between the horizontal section of the bending slide bar 431 and the horizontal sleeve 310. Further, one end of the limiting slide bar 43 close to the bending slide bar 431 is set to a slope so that the bending slide bar 431 can resist.

[0065] In the specific implementation process, by moving the bending slider 431 in the direction away from the horizontal sleeve 310, the bending slider 431 moves the stretched contraction spring 432 connected thereto. At this time, driven by 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, the inclined block 430 on the limiting slider 43 pushes the inclined block 430 and the limiting slider 43 to slide in the direction away from the rotating wheel rod 421 until the limiting slider 43 moves to the end of the sliding groove away from the rotating wheel rod 421. At this time, the slope on the limiting slider 43 contacts 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.

[0066] When the driving force driving the bending slider 431 is released, the bending slider 431 is driven by the contraction spring 432 to slide and reset in the direction close to the horizontal sleeve 310, and the bending slider 431 moves along the slope surface that conflicts with the limit slider 43, driving the limit slider 43 to slide in the direction close to the rotating wheel rod 421. After the limit slider 43 and the inclined block 430 move to conflict with the outer side surface of one of the splines on the rotating wheel rod 421, the contraction spring 432 Driven by, the vertical section of the bending slider 431 completely passes over the slope on the limiting slider 43 until one end of the slope of the limiting slider 43 contacts the horizontal section of the bending slider 431. At this time, the limiting slider 43 is limited by the horizontal and vertical sections of the bending slider 431 at the same time, thereby limiting the rotation of the rotating wheel rod 421 and the driven gear 422 from continuing to rotate, thereby achieving the effect of limiting and fixing the position of the sliding connecting rod 41 and the bending slider 311 after the sliding adjustment.

[0067] It should be noted that after the splines on the rotating wheel rod 421 are interfered with by the limiting slide rod 43 and the inclined block 430, although the rotating wheel rod 421 and the driven gear 422 can be restricted from continuing to rotate in the forward direction, since the inclined block 430 only limits and interferes with one side of one of the splines on the rotating wheel rod 421, the rotating wheel rod 421 and the driven gear 422 can still rotate in the opposite direction to a certain extent (the extent depends on the spacing between the two adjacent splines on the rotating wheel rod 421).

[0068] Based on this, when the rotating wheel rod 421 is driven to rotate to adjust and extend the positions of the bending slide bar 311 and the limiting slide bar 43, the rotating wheel rod 421 is rotated a certain amplitude (that is, the interval between two adjacent splines) to make the limiting slide bar 43 extend outward along the mounting rod 1 for a certain distance, and then the multi-rotated splines are limited by the limiting slide bar 43 and the inclined block 430. At this time, the limiting slide bar 43 and the mounting rod 1 as well as the bending slide bar 311 and the horizontal sleeve 310 are in a state allowing a certain degree of telescopic sliding. The overall length of the reel is slightly longer than the length of the rolling curtain 10, and under the reset drive of the two adjusting springs 420, the connected limiting slide bar 43 is driven to always have a tendency to protrude outward from the mounting rod 1, so as to elastically tension the rolling curtain 10 on the reel so that the rolling curtain 10 on the reel is completely fitted to the outer surface of the reel.

[0069] When the staff needs to remove the roller blind 10 on the reel, they first completely release the rolled roller blind 10 on the reel, and then drive the two limit slide bars 43 to slide towards each other. At this time, the installation head 11 inserted at the end of the limit slide bar 43 is limited by the bent slide bar 311. When the limit slide bar 43 and the connected installation head 11 are relatively displaced, the limit protrusion 21 is gradually disengaged from the groove 23 on the limit slide bar 43, completing the separation of the limit slide bar 43 and the installation head 11, and then releasing the limit of the installation head 11 on the roller blind 10, so that the staff can remove the roller blind 10 for replacement.

[0070] Reference Fig.11 and Fig.12As shown, at least two limiting seats 44 arranged in a U-shaped structure are symmetrically connected to the horizontal sleeve 310. A connecting slider 440 is slidably inserted into the limiting seat 44. A pressing spring 441 is commonly connected between the connecting slider 440 and the limiting seat 44. A limiting ring sleeve 442 is connected to the side of the connecting slider 440 away from the connected pressing spring 441. The limiting ring sleeve 442 is slidably connected to the limiting seat 44. A pressing roller 443 is rotatably pressed between the two limiting ring sleeves 442. During use, the rolling curtain 10 wound on the reel presses against the pressing roller 443, so that the pressing roller 443 generates a driving force to slide away from the reel. The movement of the pressing roller 443 drives the limiting ring sleeves 442 and the connecting slider 440 at both ends thereof to slide towards the horizontal sleeve 310, and the connected pressing spring 441 is compressed by the force. Due to the elastic restoring force of the compressed pressing spring 441, the connecting slider 440, the limiting ring sleeve 442 and the pressing roller 443 always have a tendency to slide towards the reel, so that the pressing roller 443 floats and abuts against the outer side surface of the rolling curtain 10. In normal use, a hem is generally installed on the side of the rolling curtain 10 away from the reel to increase the self-weight of the lower side of the rolling curtain 10, so that the rolling curtain 10 remains in a natural hanging state when being wound and released, thereby helping the rolling curtain 10 to be evenly wound or unfolded, and preventing the problems of knotting or wrinkling of the rolling curtain 10 when being wound.

[0071] During operation: First step, install the limiting frame 31, the mounting code 32 and the mounting head 11 on the wall corresponding to the window, then insert the end of the rolling curtain 10 with a positioning hole 100 into the mounting rod 1, and then assemble the mounting rod 1 and the mounting head 11 correspondingly to form a reel to wind the rolling curtain 10.

[0072] Second step: During the process of assembling the two mounting heads 11 at both ends of the mounting rod 1, the rolling curtain 10 is further limited by the elastic member 2 connected to the mounting head 11. After completing the assembly of the mounting head 11 and the mounting rod 1, the effect of limiting and installing the rolling curtain 10 on the reel is also synchronously completed.

[0073] Third step: When it needs to be removed, just drive the mounting heads 11 at both ends of the mounting rod 1 to separate from it, and the rolling curtain 10 can be quickly released from the limit, so that the staff can remove and replace the rolling curtain 10.
