Background technique

In the prior art, ceiling curtains generally use relatively soft honeycomb curtains or lily curtains. As the width of the curtain increases, the curtain itself is heavier and tends to fall when unfolding or closing. In order to prevent the curtain body from falling, ceiling curtains currently mainly add a support structure to the frame or curtain body to keep the curtain body from falling.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

As shown in Figures 1 to 3, an embodiment of the present invention provides a ceiling curtain with an anti-fall holding mechanism, including a front frame 11, a left guide rail frame 13, and a right guide rail frame 14; the left guide rail frame 13 is provided with The first transmission box 4 is provided with a second transmission box 5 on the right guide rail frame 14. The front frame 11 is located between the first transmission box 4 and the second transmission box 5 and is connected with the left guide rail frame 13 and the right The guide rail frames 14 together form a ceiling curtain frame. The front frame 11 is also provided with a curtain body 19. There is also a curtain body traction clamp 191 connected to the end of the curtain body 19 between the left guide rail frame 13 and the right guide rail frame 14. ; Also includes a driving component 3, which is connected to the first transmission box 4 or the second transmission box 5 for driving the curtain body traction clamp 191 on the ceiling curtain frame along the left guide rail frame 13 and the right The guide rail frame 14 moves, and the other side of the driving assembly 3 is drivingly connected to another transmission box through the first transmission member 39; after the ceiling curtain frame is installed, it is drivingly connected to the transmission boxes on both sides through the driving assembly, thereby driving The curtain body traction clamp moves horizontally along the left and right guide rail frames, and the movement process naturally drives the curtain body to expand and collapse

In the embodiment of the present invention, in order to prevent the curtain body from falling easily after unfolding or closing, an anti-fall holding mechanism 6 is added. The anti-fall holding mechanism 6 includes a fixed seat 61 installed on the front frame 11, There is a rope rolling part 62 on the fixed base 61 that can rotate relative to the fixed base 61. The rope rolling part 62 is also wrapped with an anti-falling cord 63. One end of the anti-falling cord 63 passes through the curtain body 19 and the curtain. The body traction clamp 191 is connected, and the first transmission member 39 is connected with the rope winding member 62 so that the driving assembly 3 can drive the rope winding member 62 to rotate at the same time. The anti-fall cord penetrates into the curtain body and is connected to the curtain body traction clamp. When the driving motor of the ceiling curtain drives the traction clamp to move, the winding parts of the anti-fall cord will rotate synchronously, so that the anti-fall cord can It automatically winds up as the curtain body moves. It has a simple structure and can achieve an anti-fall effect, and the anti-fall cord is not exposed on the frame.

In the embodiment of the present invention, the advantage of adopting the above structure is that the current anti-fall holding mechanism wound by the pulley group requires at least two sections of cords arranged along the moving direction of the curtain body, which is equivalent to putting the cord on one end while retracting the other end. The rope is used to maintain the straightening effect, and this solution only requires one section, which greatly saves space. Moreover, when used on a curtain body with a relatively large size, multiple groups can also be set up separately in parallel to ensure its anti-falling effect. .

In addition, as shown in FIGS. 4 to 10 , in the embodiment of the present invention, in order to ensure that the anti-fall wire rope will not be retracted too much, the rope winding member 62 retracts and releases the anti-fall wire rope 63 with the same angle. The moving speeds of the curtain body traction clamps 191 are consistent or substantially consistent. The difference between the solution and the traditional one is that the power of the traditional anti-fall cord 63 to release the rope needs to rely on the curtain body traction clamp 191. It can be understood that the curtain body traction clamp 191 pulls one end of the anti-fall cord 63 to rotate the rope winding part 62. In this solution, the rope winding member 62 can be rotated through a separate drive. It is only necessary to maintain the linear speed of the rope winding member's rotation, that is, the speed of releasing the rope and retracting the rope is consistent with the moving speed of the curtain body 19. Of course, the speed is The linear speed of the anti-fall wire rope 63. In this solution, although the curtain body and the rope winding parts are driven by the driving assembly 3, in this solution, the driving assembly 3 can include multiple independent motors to independently drive the curtain body to move and the rope winding parts to rotate. Just ensure the synchronization of its driving actions.

In this solution, the rope winding component 62 is driven together by the driving motor of the curtain body traction clamp 191. In order to ensure that the linear speed of the winding anti-fall cord is consistent with the moving speed of the curtain body, the left transmission assembly includes a left synchronous belt 131, The left transmission tooth 132 is provided in the first transmission case 4 and meshes with the left synchronous belt 131. The right transmission assembly includes a right synchronous belt 141, which is provided in the second transmission case 5 and is engaged with the left synchronous belt 131. The right synchronous belt 141 is engaged with the right transmission tooth 142 of the transmission, and the outer diameter of the rope winding member 62 is substantially consistent with the outer diameters of the left transmission tooth 132 and the right transmission tooth 142 . In this solution, the outer diameter is basically the same means that the outer circumference of the rope winding member 62, the left transmission tooth 132 and the right transmission tooth 142 are in contact with the synchronous belt in the same size, so as to ensure the linear speed of the outer circumference when the three rotate at the same speed. Similarly, the above-mentioned keeping of the rope releasing speed and the moving speed of the curtain body 19 is achieved. Of course, since there will be a rope-winding groove or a threaded groove on the surface of the rope-winding member 62 for the anti-falling wire rope 63 to be embedded, the outer diameter here is basically the same, not the outermost diameter of the rope-winding member 62, but the rope-winding groove. Or the diameter size of the thread groove (that is, the height of the groove wall is not calculated)

In this solution, the curtain body traction clamp 191 and the transmission assembly are connected in the following manner: the left synchronous belt 131 is also provided with a left moving seat 133, and the right synchronous belt 141 is also provided with a right moving seat 143. The moving base 133 and the right moving base 143 are respectively plugged into the two ends of the curtain body traction clamp 191 .

In order to make the structure simpler, in the embodiment of the present invention, the driving of the rope winding member 62 and the driving of the movement of the curtain body are the same set of driving components. The driving assembly is used to connect with the transmission box and at the same time with the rope winding member. The specific structure is that the driving assembly 3 is connected to the second transmission box 5 through the first transmission member 39, and the middle part of the rope winding member 62 is There is a shaft hole 6201 penetrating both ends along its axial direction. A transmission connection part 621 is provided in the shaft hole 6201. The first transmission member 39 passes through the transmission connection part 621 so that the driving assembly 3 drives the curtain. When the body traction clamp 191 moves, it drives the rope winding member 62 to rotate at the same time. It is ensured that the rope rolling part retracts and retracts the anti-falling cord 63 along with the forward and reverse direction of the motor, so that it is consistent with the expansion and retraction of the curtain body. The structure is simple and easy to install and use.

In addition, the transmission connection part 621 is a polygonal hole, and the outer peripheral surface of the first transmission member 39 is a polygon that matches the transmission connection part 621 . Its structure is simple and convenient for installation.

In the embodiment of the present invention, the inner peripheral wall near the end of the shaft hole 6201 is provided with a fixed rope hole 6200 that penetrates to the outer peripheral surface. The fixed rope hole 6200 is convenient for fixing one end of the anti-falling wire rope 63 so that it can be better wound around the outer peripheral surface of the rope winding member 62 .

In the embodiment of the present invention, the fixed base 61 is also provided with a rope outlet 611. One end of the anti-falling cord 63 passes through the rope outlet 611 and penetrates into the curtain body 19 and is clamped with the curtain body. 191 connection, while the rope winding member 62 rotates relative to the fixed base 61, the rope winding member 62 can move in the axial direction relative to the fixed base 61, so that the anti-falling wire rope 63 can move from the breakaway point to the rope outlet. The relative position of the mouth 611 is basically unchanged; the breakaway point refers to the position where the anti-falling wire rope 63 breaks away from the rope winding member 62 . The anti-falling cord is wound along the surface of the rope reel. The difference from the conventional one is that after the anti-fall cord is wound, it is wound in a single layer on the surface of the rope reel, which can greatly optimize the rope reel. The size is convenient for assembly and disassembly in a small space. In addition, the axial movement of the rope winding part is realized while the rope winding part is rotating, thereby keeping the position of the rope basically unchanged, thereby reducing the tension between the retraction and release of the anti-fall rope and the curtain. The speed error of body movement further achieves synchronization effect.

In the embodiment of the present invention, the relative position of the anti-falling wire rope 63 from the breakaway point to the rope outlet 611 is basically unchanged to improve the synchronization of the retracting and unfolding speed of the anti-falling wire rope 63 and the moving speed of the curtain body. Here, Basically unchanged means that it can be kept unchanged by the position-limiting anti-falling wire rope 63 disengaging from the rope winding member.

Specifically, in the embodiment of the present invention, the rope winding member 62 is in a long cylindrical shape, and the anti-falling wire rope 63 is wound around the outer periphery of the rope winding member 62 . The biggest advantage is that after the anti-falling wire rope 63 is rolled up, it is only wound one layer on the surface of the rope winding part 62. There is no need to add baffles on both sides to form wire troughs like the current rope winding part, so that the outer diameter of the rope winding part 62 can be Smaller, convenient for assembly and use in small spaces.

In the embodiment of the present invention, the axial movement of the rope-winding member 62 can be achieved through a simple thread fit. The fixed base 61 is provided with an installation opening 6101 for the rope-winding member 62 to pass through. The rope-winding member 62 There are threads extending in the axial direction on the outer circumference of the installation port 6101. The inner wall of the installation port 6101 is provided with a threaded portion that threadably matches the outer circumference of the rope winding member 62. When the rope winding member 62 rotates, it synchronously moves to the axis by cooperating with the threaded portion. towards movement. While the rope winding member is retracting and retracting the anti-falling wire rope 63, the axial movement is realized through the threaded matching structure, and the direction of the axial movement can be controlled according to the different directions of the rope, so that the anti-falling wire rope 63 can always be kept from the breakaway point to the The relative position of the rope outlet 611 remains basically unchanged.

In the embodiment of the present invention, the rope fixing holes 6200 are provided on both sides of the shaft hole 6201 near the ends, and the two rope outlet openings 611 are provided on the fixed base 61 . Since this solution uses the driving assembly to drive the curtain body to move and the rope winding member to rotate, the driving assembly 3 can be installed on one side of the first transmission box 4 or on one side of the second transmission box 5, which is equivalent to installing the The scene can be installed on both sides of the fixed base 61 . In order to adapt to this installation method, this solution also provides two rope exits 611 and fixed rope holes 6200, which can be understood as being symmetrically arranged on the fixed base 61, so as to adapt to different installation positions and different directions of the driving assembly 3 to install the anti-locking device. The falling wire rope 63 is used to ensure that the retraction of the anti-falling wire rope 63 is consistent with the moving direction of the curtain body.

Specifically, the fixing base 61 is provided with an installation opening 6101 for the rope reel 62 to pass through. After installation, the two ends of the rope reel 62 extend outward from both sides of the installation opening 6101. Therefore, this solution also provides two A rope outlet 611 is provided to facilitate the installation and use of the anti-falling wire rope 63. Specifically, since the rope reel 62 protrudes from both sides of the installation opening 6101 after installation, the anti-falling wire rope 63 can only be wrapped around the rope reel 62 exposed on the left side of the installation opening or on the right side of the installation opening. On the rope rolling part 62 on the side, the solution is provided with rope outlets 611 on both sides for passing out, that is, one end of the anti-falling wire rope 63 is fixed on the fixed rope hole 6200 on the left side. And the other end passes through the rope outlet 611 near the left side, or one end of the anti-falling wire rope 63 is fixed on the fixed rope hole 6200 on the right side and the other end passes through the rope outlet 611 near the right side. out.

In addition, in the embodiment of the present invention, the bottom of the fixed base 61 is also provided with a downwardly extending connecting protrusion 610 . The connecting bump 610 facilitates the quick installation of the fixed base 61. For example, in this solution, multiple holes can be opened on the front frame 11, which can be used for the anti-fall wire rope 63 to pass through, and can also be used for the connecting bump 610 to be inserted. Install.

Optimally, in the embodiment of the present invention, a spiral groove is formed on the outer periphery of the rope winding member 62, and the anti-falling wire rope 63 is wound along the spiral groove. It can not only cooperate with the threaded fitting portion to realize the axial movement of the rope winding member 62, but also serve as a groove to limit the anti-fall wire rope 63, thereby maintaining the position of the anti-fall wire rope 63 after being wound, and can also maintain the anti-fall wire. The relative position of the rope 63 from the breakaway point to the rope outlet 611 is basically unchanged, further improving the anti-falling effect.

Error to avoid affecting the anti-falling effect of the curtain body, and the tensioning component of this solution has a simple structure, using the elasticity effect of the elastic member itself, and the anti-falling wire rope can be directly connected.

Moreover, this solution uses elastic parts to compensate for the length error produced during the manufacture or installation of the anti-fall rope, achieving the effect of automatic error compensation. It is further realized that the anti-falling rope can be kept in a straightened and tensioned state, and in addition, the elastic component can absorb the retracting and unwinding tension of the rope-reeling component, which can provide a good buffering and protection effect on both the rope-reeling component and the anti-falling rope.
