Description

Technical Field

[0001] The utility model relates to the technical field of curtains, and more specifically, to a stop-and-go rolling curtain mechanism with a spring inside a roller and a hand-held curtain. Background Art

[0002] Existing spring rolling curtain devices generally include brackets on both sides and a roller. A spring rod is arranged inside the roller, a limiting spring is sleeved on the spring rod, and a spring end plug is installed at the end of the limiting spring. The resilience of the limiting spring needs to be pre-tensioned according to the size and weight of the curtain. In the patent with the application number 201821249939.1, a hand-held zebra curtain is disclosed. The following problems exist in this patent: The hand-held zebra curtain includes a curtain fabric roller and a winding device. The spring piece, the spring piece fixing disk, and the spring piece winding disk of the winding device are all arranged inside a bracket housing (the bracket housing is formed by buckling an outer shell and an end cover), which will cause the thickness of the bracket housing in the horizontal direction to be relatively thick. As a result, the gap between the side end face of the bracket housing away from the curtain fabric and the curtain fabric is relatively large, resulting in serious light leakage at the gap and poor use experience. In addition, the bracket housing for installation is formed by buckling an outer shell and an end cover, with a relatively complex structure and high production cost. Summary of the Utility Model

Detailed implementation manners

[0026] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship during the normal use of the product.

[0028] The terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0029] Embodiment 1:

[0030] Refer to Figures 1 - 8 , Embodiment 1 of the present utility model provides a stop-with-winding roller blind mechanism with a spring built into a reel, including: a mounting frame 1, a winding device, and a reel 2 connected to the winding device. The reel 2 is used to connect the curtain fabric, and the winding device is used to wind the reel 2. The winding device includes a rotating assembly and a spring assembly 4. The rotating assembly includes a fixed part 5 fixedly connected to the mounting frame 1 and a rotating part 3 that can rotate along its own circumferential direction. The rotating part 3 rotates synchronously with the reel 2. When the rotating part 3 rotates, it has a first direction for raising the curtain fabric and a second direction for lowering the curtain fabric, and the first direction and the second direction are opposite. The spring assembly 4 is connected to the rotating part 3 and rotates synchronously therewith, and the spring assembly 4 is placed inside the reel 2; when the rotating part 3 rotates around the second direction (as shown by the arrow in the attachment Figure 1 ), the spring assembly 4 stores potential energy; by releasing the potential energy stored in the spring assembly 4, the spring assembly 4, the rotating part 3, and the reel 2 are driven to rotate and reset around the first direction to raise and wind the curtain fabric. The present utility model places the spring assembly inside the reel, enabling the thickness of the mounting frame to be greatly reduced, narrowing the gap L between the side end face of the mounting frame away from the curtain fabric 9 and the curtain fabric 9, reducing light leakage, and the structure of the mounting frame is simple with low production cost.

[0031] Refer to Figures 1 - 4 , the rotating part 3 includes an outer housing 31. The outer housing 31 includes a plunger main body 311. The plunger main body 311 is placed inside the reel 2, with a compact structure and a hidden design inside the reel 2, avoiding the structure from increasing the gap between the curtain fabric and the mounting frame; a limiting groove 312 is provided on the outer housing 31, and a limiting protrusion 21 corresponding to the limiting groove 312 is provided on the inner side of the reel 2, enabling the outer housing 31 to rotate synchronously with the reel 2; the rotating assembly further includes a first output shaft 6. The first output shaft 6 is eccentrically arranged at the side end of the outer housing 31 close to the spring assembly 4. The first output shaft 6 is used to connect and drive the spring assembly 4 for energy storage. When the rotating part 3 rotates, it drives the first output shaft 6 to rotate, and thus the spring assembly 4 is energized through the rotation of the rotating part 3. When the spring assembly 4 releases potential energy, it can drive the rotating part 3 to rotate and reset.

[0032] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, a transmission component is provided between the first output shaft 6 and the fixed part 5. When the rotating part 3 rotates relative to the fixed part 5, the first output shaft 6 is driven to rotate through the transmission component. Before installation (or before leaving the factory), the coiling device needs to be pre-tightened, that is, the rotating part 3 needs to be rotated relative to the fixed part 5 by a certain number of turns to ensure that the curtain can be completely wound up. The specific number of turns is set according to parameters such as the size and weight of the curtain; the transmission component includes a first connecting block 61, a second connecting block 62 and an intermediate movable block 63 arranged inside the outer shell 31. The first connecting block 61 is connected to the fixed part 5. A plugging square shaft 612 is arranged on the first connecting block 61, and a plugging square hole 56 corresponding to the connecting square shaft 612 is arranged on the fixed part 5; the second connecting block 62 is arranged at one end of the first output shaft 6 away from the spring assembly 4, and the intermediate movable block 63 is movably connected between the first connecting block 61 and the second connecting block 62. The first connecting block 61 is provided with a first convex block 611, the second connecting block 62 is provided with a second convex block 621, and the intermediate movable block 63 is provided with a first sliding groove 631 slidably matched with the first convex block 611 and a second sliding groove 632 slidably matched with the second convex block 621. The extending direction of the first sliding groove 631 and the extending direction of the second sliding groove 632 are perpendicular to each other; the first connecting block 61 and the second connecting block 62 are driven by the intermediate movable block 63, so that when one of the first connecting block 61 and the second connecting block 62 rotates along its own circumferential direction, the other connecting block is driven to rotate along its own circumferential direction; conversely, when one does not rotate along its own circumferential direction, the other connecting block will not rotate along its own circumferential direction; thus, when the coiling device is installed with the mounting frame, neither the first connecting block 61 nor the second connecting block 62 rotates along its own circumferential direction. When the rotating part 3 rotates, the second connecting block 62 rotates along the circumferential direction of the outer shell 31 and does not rotate along its own circumferential direction.

[0033] Refer to Figure 2 , Figure 3 and Figure 7, the spring assembly 4 includes a housing 41. One end of the housing 41 is provided with an input shaft hole 411 for storing and applying force to the spring assembly 4. The input shaft hole 411 is adapted to the first output shaft 6. The first output shaft 6 is a square shaft, and the input shaft hole 411 is a square hole. The spring assembly 4 further includes a coiled spring 42 and a rotating spring shaft 43 disposed within the housing 41. The coiled end of the coiled spring 42 is snap-connected to the rotating spring shaft 43. The input shaft hole 411 is disposed at one end of the rotating spring shaft 43. When the rotating part 3 rotates in the second direction, the rotating spring shaft 43 is driven to rotate through the first output shaft 6, thereby pulling out a part of the coiled spring 42 to enable the spring assembly 4 to store potential energy. When the spring assembly 4 releases potential energy, the rotating part 3, the first output shaft 6, the rotating spring shaft 43, and the coiled spring 42 are reset. In use, a counterweight can be installed on the lower rod of the curtain to increase the counterweight. When the curtain is manually hovered, the weight of the curtain reaches equilibrium with the rewinding force of the spring assembly 4. When the curtain is pushed upward, due to the loss of balance, the rewinding force of the spring assembly 4 is greater than the weight of the curtain. At this time, the potential energy is released to achieve the function of raising the curtain. When in use, pulling the lower rod of the curtain can achieve stopping as it is pulled.

[0034] Refer to Figures 2 - 5 , the fixing part 5 includes a fixing sleeve 51, a manual adjustment turntable 52, and a fixing column 53. The manual adjustment turntable 52 includes a disc body 521 and an annular column 522. The fixing column 53 is placed inside the annular column 522. A holding spring 54 is provided between the fixing column 53 and the annular column 522 to enable the fixing column 53 and the annular column 522 to be held tightly. There are two holding springs 54 to ensure sufficient holding force. A first clamping block 101 is provided on the mounting bracket 1 by bending. A first clamping groove 531 for clamping with the first clamping block 101 is provided on the side end of the fixing column 53. The annular column 522 is placed inside the fixing sleeve 51. A second clamping block 511 is provided inside the fixing sleeve 51. A clamping notch 5221 corresponding to the second clamping block 511 is provided on the annular column 522 to limit the relative rotation between the annular column 522 and the fixing sleeve 51. The fixing sleeve 51, the annular column 522, the holding spring 54, and the fixing column 53 are all placed inside the outer housing 31, with a compact structure. The outer housing 31 and the spring assembly 4 are snap-connected through a snap structure 8, which is convenient for assembly. Users or installers can manually pre-tighten the spring assembly through the manual adjustment turntable 52, and the tightening amount can be adjusted by themselves, which is not easy to waste the number of tightening turns of the spring assembly.

[0035] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 7, the mounting bracket 1 is a sheet-like body with a small thickness, which is convenient for reducing light leakage. The mounting bracket 1 is a metal sheet formed by bending, with a simple structure and low production cost. One or several winding spring assemblies 4 are arranged along the axial direction. When several winding spring assemblies 4 are provided, adjacent two winding spring assemblies 4 are clamped by a buckle. Input shaft holes 411 and second output shafts 40 which are adapted to each other are respectively arranged at both ends of the winding spring assembly 4. The second output shaft 40 is integrally formed at one end of the rotary spring shaft 43 far away from the input shaft hole 411. Among adjacent two winding spring assemblies 4, the second output shaft 40 of one winding spring assembly 4 is inserted into and synchronously rotates with the input shaft hole 411 of the other winding spring assembly 4. Multiple groups of winding spring assemblies 4 can be set to increase the rewinding force of the curtain cloth, so as to wind the curtain cloth with a wide width and large size, and the application range is wide. The number of winding spring assemblies 4 is set according to parameters such as the size and weight of the curtain and the rewinding force of the winding spring assembly 4. The setting method of the coiling spring 42 is as follows: for small curtains, narrow / thin coiling springs 42 can be selected; for large curtains, wide / thick coiling springs 42 can be selected to increase the rewinding torque. According to the matching of the rewinding force of different coiling springs 42 and the rewinding force required by different curtains, the number of groups of winding spring assemblies 4 is correspondingly set, and the use is more flexible.

[0036] Embodiment 2:

[0037] Refer to Figures 9 - 11 , the main difference between this Embodiment 2 and Embodiment 1 is that: the fixing part 5 includes a fixing shaft 55, a first connecting block 61 is integrally connected to one end of the fixing shaft 55, a first clamping block 101 is arranged on the mounting bracket 1, a second clamping groove 551 for clamping with the first clamping block 101 is arranged on the side end of the fixing shaft 55, a pin 7 is detachably inserted into the outer shell 31, a plurality of third clamping grooves 552 corresponding to the pin 7 are annularly arranged on the fixing shaft 55, and one end of the pin 7 passes through the outer shell 31 and is clamped into one of the third clamping grooves 552 for limiting, so as to limit the relative rotation between the fixing shaft 55 and the outer shell 31. For the winding device in this Embodiment 2, the winding spring assembly can be pre-tightened before leaving the factory, and this pre-tightened force is locked by the pin 7. When the user or installer installs, only need to pull out the pin 7 to utilize this pre-tightened force without re-tightening, making the installation more convenient.

[0038] The stop-at-any-point rolling curtain mechanism of the utility model has a winding spring built inside the reel. By placing the winding spring assembly inside the reel, the thickness of the mounting bracket can be greatly reduced, the gap between the side end face of the mounting bracket and the curtain fabric can be narrowed, light leakage can be reduced, and the structure of the mounting bracket is simple with low production cost. The rotating part includes an outer shell body which includes a plunger main body placed inside the reel. The structure is compact, and the hidden design inside the reel avoids increasing the gap between the curtain fabric and the mounting bracket. In the structure with a manual adjustment turntable, users or installers can manually pre-tighten the winding spring assembly through the manual adjustment turntable, and the tightening amount can be adjusted by themselves, so it is not easy to waste the number of tightening turns of the winding spring assembly. In the structure with a detent pin, the winding spring assembly can be pre-tightened before leaving the factory and the tightened force of this part can be locked by the detent pin. When users or installers install it, they only need to pull out the detent pin to utilize this part of the tightened force without re-tightening, making the installation more convenient. According to the matching of the return force of different coiled springs and the return force required by different curtains, the number of groups of the winding spring assembly is set correspondingly, making it more flexible to use.

[0039] The utility model also provides a hand-held curtain, which includes the stop-at-any-point rolling curtain mechanism with the winding spring built inside the reel. This hand-held curtain also has the beneficial effects of the stop-at-any-point rolling curtain mechanism with the winding spring built inside the reel, which will not be elaborated here.

[0040] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
