The rolling curtain main body includes a curtain fabric 1; the curtain fabric fixing assembly 4 includes a deformable member 41 connected to the bottom end of the curtain fabric 1. When the curtain fabric 1 is wound to a preset position, both ends of the deformable member 41 are connected and fixed to form a closed loop structure, and the closed loop structure fixes the posture of the curtain fabric 1.

[0038] Compared with the prior art, for the simple retractable rolling curtain provided by the present utility model, when the curtain fabric 1 is wound to a preset position, the deformable member 41 is a closed loop structure. The closed loop structure is sleeved on the curtain fabric 1, so that the closed loop structure and the curtain fabric are in a stable connection state, thereby realizing the locking of the curtain fabric 1 wound to the preset position. When it is necessary to unfold the curtain fabric 1, the connection state between the closed loop structure and the curtain fabric 1 can be released. This rolling curtain does not use a pull rope structure, can be manually retracted and extended, has safe use, good applicability, and low production and manufacturing costs. The operation is simple and fast, greatly improving the convenience during use.

[0039] As a specific implementation manner of an embodiment of the present utility model, please refer to Figures 1 to 11, the deformable member 41 includes: a first deformable body 411 and a second deformable body 412. The first deformable body 411 is connected to the bottom end of the curtain fabric 1, and the first connection end of the first deformable body 411 extends along one side of the curtain fabric 1; the second deformable body 412 is connected to the bottom end of the curtain fabric 1, and the second connection end of the second deformable body 412 extends along the other side of the curtain fabric 1; when the curtain fabric 1 is wound up, the first deformable body 411 and the second deformable body 412 move upward along with the winding center of the curtain fabric 1 respectively; after the curtain fabric 1 reaches the preset winding height, the first connection end and the second connection end respectively turn back from one side of the curtain fabric around the edge of the curtain fabric, and the first connection end and the second connection end are connected to form a closed loop structure. In this embodiment, the first connection end and the second connection end can be connected and fixed by bundling. That is, the first connection end and the second connection end are respectively belt-like structures. That is, when a closed loop structure needs to be formed, the first connection end and the second connection end are bundled to form a slipknot structure. When the curtain fabric 1 needs to be unfolded, the slipknot structure is released.

[0040] In any implementable embodiment, the curtain fabric fixing assembly 4 further includes a fixing member 42 connected to the deformable member 41, and the fixing member 42 realizes the connection and fixation of both ends of the deformable member 41 by one or more of bonding, magnetic connection, plugging, and clamping methods.

[0041] In this embodiment, the fixing member 42 is one or more of a magic tape, a connecting buckle, a magnetic snap, and a button.

[0042] In any feasible embodiment, the deformable member 41 is a flexible member. The deformable member 41 is connected and fixed to the bottom end of the curtain 1 in a horizontal state. Specifically, the first deformable member 411 is fixed to the bottom of the curtain 1 and is a flexible member. One end of the first deformable member 411 extends horizontally toward one side of the curtain 1. The extension length of the first deformable member 411 is greater than 1 / 2 of the width of the curtain 1. When the curtain 1 is rolled up, the first deformable member 411 moves upward along the rolling center of the curtain 1. After reaching the required rolling height, the extended end of the first deformable member 411 can be folded back from one side of the curtain 1 around the edge of the curtain 1 and connected to the second deformable member 412. The first deformable member 411 and the second deformable member 412 are connected by the fixing member 42, so that the first deformable member 411, the second deformable member 412 and the curtain 1 form a closed loop, which plays a role in fixing the curtain 1. The second deformable body 412 is fixed at the bottom of the curtain 1 and is a flexible component. One end of the second deformable body 412 extends in the opposite direction of the extended end of the first deformable body 411. When the curtain 1 is rolled up, the second deformable body 412 moves upward along with the rolling center of the curtain 1. After reaching the required rolling height, the extended end of the second deformable body 412 can be folded back from one side of the curtain 1 around the edge of the curtain 1 and connected to the first deformable body 411 through the fixing member 42 to form a closed loop, thereby fixing the rolled portion of the curtain 1. The function of the fixing member 42 is to fix the first deformable body 411 and the second deformable body 412 when necessary. The specific components of the fixing member 42 can be installed on the first deformable body 411 and the second deformable body 412 or can be relatively independent.

[0043] Example 1: The first deformable body 411 is a flexible webbing, which is transversely fixed below the curtain 1 by means of gluing or rivets. One end of the first deformable body 411 extends transversely outward to one side of the curtain 1. When the curtain 1 is rolled up, the first deformable body 411 moves upward with the center of the curtain rolling up. After reaching the required position, its extended end is folded back from the side of the rolled curtain 1 and connected to the second deformable body 412 on the other side through the fixing member 42, thereby fixing the curtain 1 in the rolled position. The second deformable body 412 is a flexible webbing, which is transversely fixed below the curtain 1 by means of gluing or rivets. One end of the second deformable body 412 extends in the opposite direction to the extended end of the first deformable body 411. Similarly, when the curtain 2 is rolled up, the second deformation body 412 moves upward with the rolling center of the curtain 1, and after reaching a certain height, its extended end is folded back from the side of the curtain relative to the extended end of the first deformation body 411 and connected to the first deformation body 411 on the other side through the fixing member 42, thereby fixing the curtain 1. The fixing member 42 is a Velcro, and its molecular mother, one of which is set on one side (front or back) of the first deformation body 411, and the corresponding part is set on the side of the second deformation body 412 relative to the first deformation body 411. The first deformation body 411 and the second deformation body 412 can be connected and closed by the Velcro.

[0044] Example 2: The structure of the deformable part 41 is the same as that described in Example 1. Only the fixing part 42 is different, so the other parts will not be described in detail.

[0045] The fixing part 42 is a snap-fastener, which consists of part a and part b. Among them, part a and part b can be snapped together relatively. Part a and part b are respectively arranged in a number of evenly distributed on the first deformable body 411 and the second deformable body 412, and are arranged oppositely. Part a and part b can be freely paired and snapped together to adjust the connection distance between the first deformable body 411 and the second deformable body 412. More specifically, the snap-fastener can be a magnetic snap.

[0046] Example 3: The structure of the deformable part 41 is the same as that described in Example 1. Only the fixing part 42 is different, so the other parts will not be described in detail.

[0047] The fixing part 42 is a plug-in fastener, which is divided into two parts: a plug and a socket. The plug and the socket are respectively fixed at the extension ends of the first deformable body 411 and the second deformable body 412. And at least one of the fixed ends of the plug or the socket can adjust the distance relative to the first deformable body 411 and the second deformable body 412, and further can adjust the connection distance between the first deformable body 411 and the second deformable body 412.

[0048] In any achievable embodiment, the first deformable body 411 and the second deformable body 412 are of an integral structure. That is, the deformable part 41 is of an elastic belt structure. The first deformable body 411 and the second deformable body 412 are respectively partial structures of the elastic belt structure. The two ends of the elastic belt structure are respectively connected and fixed to the two ends of the bottom end of the curtain fabric 1.

[0049] As a specific implementation manner of the embodiment of the present utility model, please refer to Figures 1 to 10 , the rolling curtain main body further includes a beam body assembly 2 connected to the curtain fabric 1 and an installation assembly 3 connected to the beam body assembly 2; it should be noted that the curtain fabric 1 and the beam body assembly 2 are prior arts, and are not the focus of this case. Therefore, for the sake of saving space, this case will not be described in detail. The installation assembly 3 includes: a support seat 31, a support block 32, an anti-slip structure 33 and a state adjusting member 34. The support seat 31 is connected to the beam body assembly 2; the support block 32 is slidably connected to the support seat 32; the anti-slip structure 33 is arranged on the support block 32; the state adjusting member 34 is movably connected to the support block 32. The state adjusting member 34 can drive the relative movement between the support block 32 and the support seat 31, and limit the connection posture between the support block 32 and the support seat 31

[0050] In this embodiment, the support seat 31 is provided with a positioning groove 311 for limiting the relative movement direction between the support block 32 and the support seat 31; the support block 32 is provided with a slider 321 adapted to the positioning groove 311.

[0051] Specifically, the installation component 3 is arranged at both ends of the beam component 2 and is fixed below the beam component 2 by screws.

[0052] The support base 31 is a support fixed to one end of the upper beam component 2, and is integrally L-shaped. A plurality of mounting holes 314 are provided on its horizontal end face, and it can be mounted on the upper beam component 2 by screws.

[0053] A positioning groove 311 is provided on the horizontal end face of the support base 31. The positioning groove 311 cooperates with the positioning rib (i.e., the slider 321) on the support block 32, enabling the support block 32 to slide horizontally relative to the support base 31. A round hole 312 is provided on the vertical end face of the support base 31, allowing the threaded rod on the support block 32 to pass through it. A slot hole 313 is provided inside the vertical end face of the support base 31. The slot hole 313 can position the state adjusting member 34, preventing the state adjusting member 34 from moving horizontally relative to the support base 31. The support block 32 is integrally L-shaped and is used to adjust the distance from the support surface, playing a role in tightening. A positioning rib (i.e., the slider 321) is provided on the horizontal end face of the support block 32, which cooperates with the positioning groove 311 to enable the support block 32 to move horizontally along the positioning groove 311. A receiving groove 322 is provided on the outer side of the vertical end face of the support block 32 for receiving and installing the anti-slip structure 33. A threaded rod 323 is provided on the inner side of the vertical end face of the support block 32. It passes through the round hole 312 on the support base and cooperates with the locking nut (i.e., the state adjusting member 34). Driven by the locking nut (i.e., the state adjusting member 34), the support block 32 can move relative to the support base 31. The tightening nut (i.e., the state adjusting member 34) is located on the support base 31, and a circular ring is provided at the bottom, which is installed in the slot hole and positioned. It can adjust the movement of the support block 32 relative to the support base 31, adjust the distance between the support block 32 and the support surface, and make the support block 32 tightly press against the support surface or release it. The tightening nut is a sheep's horn nut. The anti-slip structure 33 is installed in the groove of the support block and contacts the support surface to prevent the installation component from sliding relative to the support surface after being tightened. The anti-slip structure 33 is a silica gel pad. The installation component 3 contacts and tightens with the support surface, and can support the rolling curtain without drilling holes in the window frame and door frame. It has the characteristics of more convenient use, stable cooperation between components, and not easy to separate.
