Description

Technical Field

[0001] The utility model relates to a curtain, in particular to a quick-release component, a connecting mechanism and a curtain sliding device. Background Art

[0002] There are some problems with the connection structure between the slider and the curtain piece on the current market, especially in terms of installation and stability in the horizontal direction. Electric curtains usually use a motor to drive the synchronous belt to drive the slider on the track, so that the curtain piece can be unfolded or folded. However, the existing connection structure between the slider and the curtain piece is usually installed and clamped in the horizontal direction, which makes it easy to detach in the horizontal direction after installation. Although some designs try to add a locking limit structure to improve the firmness of the connection, this often makes the disassembly and installation process cumbersome, affecting the user experience. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a quick-release assembly, a connecting mechanism and a curtain sliding device.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A quick-release assembly, comprising a first connecting block and a second connecting block, wherein the first connecting block comprises a first sliding portion, a mounting hole and a limiting hole in sequence along a height direction, the mounting hole and the limiting hole are connected, the diameter of the mounting hole is larger than the diameter of the limiting hole, and the first sliding portion is used to cooperate with a guide rail;

[0006] The second connecting block includes a second sliding portion, a first limiting portion and a second limiting portion in sequence along the horizontal direction, the second sliding portion is used to connect the curtain piece, wherein the outer diameter of the second limiting portion is larger than the outer diameter of the first limiting portion and smaller than the hole diameter of the mounting hole, and the first limiting portion can be assembled into the limiting hole through the connection between the mounting hole and the limiting hole.

[0007] In the present solution, the first connecting block and the second connecting block can be installed and limited by the installation holes and the limiting holes, which is convenient for disassembly and assembly; the design of the first limiting part, the second limiting part and the limiting hole, combined with the effect of gravity, effectively limits the freedom of the two connecting blocks in the height direction. In addition, through the mutual cooperation of the first limiting part, the second limiting part and the limiting hole, and the aperture design of the limiting hole, the freedom of the connecting part in the horizontal direction is limited to ensure that it is not easy to detach after installation. By comprehensively limiting the freedom of the two connecting blocks in the horizontal and height directions, the stability of the entire electric curtain system is improved.

[0008] Preferably, the first sliding portion is staggered from the mounting hole and the limiting hole in a height direction.

[0009] In this solution, the quick-release assembly allows more than two first connecting blocks to be arranged on the same track by staggering the first sliding portion, the mounting hole and the limit hole in the height direction, so that more than two curtain pieces can be controlled by one track, and the track space can be used more effectively.

[0010] Preferably, the first connecting block comprises a connecting plate extending in a height direction, the connecting plate is connected to a side portion of the first sliding portion, and the mounting hole and the limiting hole are provided on the connecting plate.

[0012] Preferably, the distance between the centers of the mounting hole and the limiting hole is greater than the radius of the mounting hole.

[0013] In the present solution, since the center distance between the mounting hole and the limiting hole is greater than the radius of the mounting hole, the side wall of the first connecting block at the connection point between the mounting hole and the limiting hole can form two limiting connecting parts, and the distance between the two limiting connecting parts is smaller than the aperture of the limiting hole. During the process of assembling the first limiting part to the limiting hole, the two limiting connecting parts form an obstruction to the first limiting part, and when the first limiting part is fully engaged, an engagement sound feedback is generated to enhance the user's perception and ensure that the two connecting blocks have been assembled in place.

[0014] Preferably, the second connection block further comprises a protrusion provided on the first limiting portion, and the protrusion abuts against a hole wall of the limiting hole to limit the second connection block from rotating relative to the first connection block.

[0015] In this solution, the second connecting block also includes a protrusion provided on the first limiting portion, which abuts against the hole wall of the limiting hole, effectively limiting the rotation of the second connecting block relative to the first connecting block, further enhancing the stability of the connection and preventing accidental disengagement.

[0016] The utility model also discloses a connecting mechanism, which comprises the quick-release assembly mentioned above.

[0017] Preferably, the connecting mechanism further comprises a fixing frame, the fixing frame is used to fix the curtain piece, a guide groove is provided on the fixing frame, the second sliding part is slidably matched with the guide groove, both groove walls of the guide groove are provided with a limiting protrusion, the limiting protrusion is arranged close to the notch of the guide groove, and the second sliding part is provided with a limiting recess matched with the limiting protrusion;

[0018] Alternatively, both groove walls of the guide groove are provided with limiting recesses, the limiting recesses are arranged close to the groove opening of the guide groove, and the second sliding part is provided with a limiting protrusion that cooperates with the limiting recesses.

[0019] In this solution, the limiting cooperation of the limiting protrusion and the limiting recess ensures that the second sliding part will not detach from the groove when sliding in the guide groove, thereby improving the reliability of the connection, preventing accidental falling off, and enhancing the stability of the curtain and the safety of operation.

[0020] Preferably, a first threaded hole is formed on the second connecting block and passes through the second sliding portion, the first limiting portion and the second limiting portion in sequence, and the first threaded hole is used to cooperate with a fastener to fix the second connecting block on the fixing frame.

[0021] In this solution, the design of the second connecting block allows it to be fixed on the fixing frame by fasteners, or to be slid along the guide groove on the fixing frame to adjust its position, so that the curtain piece can be fixed at different positions as needed, providing higher flexibility.

[0022] The utility model also discloses a curtain sliding device, which comprises the above-mentioned connecting mechanism.

[0023] Preferably, the curtain sliding device includes a plurality of track grooves, and the connecting mechanism is provided in each of the plurality of track grooves, and the connecting mechanism also includes a transmission member, and the transmission member is slidably matched with the guide groove, and a second threaded hole is provided on the transmission member, and the second threaded hole is used to cooperate with a fastener to fix the transmission member on the fixed frame, and the connecting mechanisms in adjacent track grooves are transmitted through the transmission member.

In addition, through the mutual cooperation of the first limiting part, the second limiting part and the limiting hole, and the aperture design of the limiting hole, the freedom of the connecting part in the horizontal direction is limited to ensure that it is not easy to detach after installation. By comprehensively limiting the freedom of the two connecting blocks in the horizontal and height directions, the stability of the entire electric curtain system is improved.

[0060] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0061] like Figure 1-Figure 11 As shown, the utility model discloses a curtain sliding device, which includes a connecting mechanism, and the connecting mechanism includes a quick-release assembly 1, wherein the quick-release assembly 1 includes a first connecting block 11 and a second connecting block 12, the first connecting block 11 includes a first sliding portion 111, a mounting hole 112 and a limiting hole 113 in sequence along the height direction, the mounting hole 112 and the limiting hole 113 are connected, the aperture of the mounting hole 112 is larger than the aperture of the limiting hole 113, and the first sliding portion 111 is used to cooperate with a guide rail; the second connecting block 12 includes a second sliding portion 121, a first limiting portion 122 and a second limiting portion 123 in sequence along the horizontal direction, the second sliding portion 121 is used to connect the curtain piece, wherein the outer diameter of the second limiting portion 123 is larger than the outer diameter of the first limiting portion 122 and smaller than the aperture of the mounting hole 112, and the first limiting portion 122 can be assembled into the limiting hole 113 through the connection between the mounting hole 112 and the limiting hole 113.

[0062] In this embodiment, the first connecting block 11 and the second connecting block 12 can be installed and limited by the installation hole 112 and the limiting hole 113, which is convenient for disassembly and assembly; the design of the first limiting portion 122, the second limiting portion 123 and the limiting hole 113, combined with the effect of gravity, effectively limits the freedom of the two connecting blocks in the height direction. In addition, through the mutual cooperation of the first limiting portion 122, the second limiting portion 123 and the limiting hole 113, and the aperture design of the limiting hole 113, the freedom of the connecting part in the horizontal direction is limited, ensuring that it is not easy to detach after installation. By comprehensively limiting the freedom of the two connecting blocks in the horizontal and height directions, the stability of the entire electric curtain system is improved.

[0063] like Figure 2 As shown, the first sliding portion 111 is staggered with the mounting hole 112 and the limiting hole 113 in the height direction. The quick release assembly 1 allows more than two first connecting blocks 11 to be arranged on the same track by staggering the first sliding portion 111 and the mounting hole 112 and the limiting hole 113 in the height direction, so that more than two curtain pieces can be controlled by one track, and the track space can be used more effectively.

[0064] like Figure 2 As shown, the first connection block 11 includes a connection plate 114 extending in the height direction, the connection plate 114 is connected to the side of the first sliding part 111, and the mounting hole 112 and the limiting hole 113 are opened on the connection plate 114. By introducing the connection plate 114 extending in the height direction into the first connection block 11, so that it is connected to the side of the first sliding part 111, and the mounting hole 112 and the limiting hole 113 are provided on the connection plate 114, it is convenient to realize that the first sliding part 111 and the mounting hole 112 and the limiting hole 113 are staggered in the height direction.

[0065] like Figure 3 As shown, the distance between the centers of the mounting hole 112 and the limiting hole 113 is greater than the radius of the mounting hole 112. Since the distance between the centers of the mounting hole 112 and the limiting hole 113 is greater than the radius of the mounting hole 112, the side wall of the first connection block 11 at the connection between the mounting hole 112 and the limiting hole 113 can form two limiting connection parts 115, and the distance between the two limiting connection parts 115 is smaller than the aperture of the limiting hole 113. During the process of assembling the first limiting part 122 to the limiting hole 113, the two limiting connection parts 115 form an obstruction to the first limiting part 122, and when the first limiting part 122 is fully engaged, an engagement sound feedback is generated to enhance the user's perception and ensure that the two connection blocks have been assembled in place.

[0066] like Figure 1 and Figure 4As shown, the second connection block 12 also includes a protrusion 124 provided on the first limiting portion 122, and the protrusion 124 abuts against the hole wall of the limiting hole 113 to limit the rotation of the second connection block 12 relative to the first connection block 11. The second connection block 12 also includes a protrusion 124 provided on the first limiting portion 122, and the protrusion 124 abuts against the hole wall of the limiting hole 113, effectively limiting the rotation of the second connection block 12 relative to the first connection block 11, further enhancing the stability of the connection and preventing accidental disengagement.

[0067] like Figure 5 and Figure 6 As shown, the connecting mechanism also includes a fixing frame 2, which is used to fix the curtain piece. A guide groove 21 is provided on the fixing frame 2, and the second sliding portion 121 slidably cooperates with the guide groove 21. A limiting protrusion 211 is provided on both groove walls of the guide groove 21. The limiting protrusion 211 is arranged close to the notch of the guide groove 21, and a limiting recess 1211 cooperating with the limiting protrusion 211 is provided on the second sliding portion 121.

[0068] Of course, in other alternative embodiments, it can also be arranged that both groove walls of the guide groove 21 are provided with a limiting recess 1211, the limiting recess 1211 is arranged close to the notch of the guide groove 21, and the second sliding part 121 is provided with a limiting protrusion 211 that cooperates with the limiting recess 1211. Through the limiting cooperation between the limiting protrusion 211 and the limiting recess 1211, it is ensured that the second sliding part 121 will not be separated from the notch when sliding in the guide groove 21, thereby improving the reliability of the connection, preventing accidental falling off, and enhancing the stability of the curtain and the safety of operation.

[0069] like Figure 4 and Figure 5 As shown, the second connection block 12 is provided with a first threaded hole 125 which sequentially passes through the second sliding portion 121, the first stop portion 122 and the second stop portion 123, and the first threaded hole 125 is used to cooperate with a fastener to fix the second connection block 12 on the fixing frame 2. The design of the second connection block 12 allows it to be fixed to the fixing frame 2 by a fastener, or to slide and adjust its position along the guide groove 21 on the fixing frame 2, so that the curtain piece can be fixed at different positions as needed, providing higher flexibility.

[0070] Specifically, Figure 5 and Figure 6 As shown, a C-shaped clip 22 extending along the length direction is provided below the fixing frame 2, and the C-shaped clip 22 is used to penetrate and fix the curtain piece. Of course, in other alternative embodiments, other connecting structures can also be provided to fix the curtain piece.

[0071] like Figure 7-Figure 11As shown, the curtain sliding device also includes a plurality of track grooves 3, and a connection mechanism is provided in each of the plurality of track grooves 3. The connection mechanism also includes a transmission member 4, and the transmission member 4 is slidably matched with the guide groove 21. A second threaded hole 41 is provided on the transmission member 4. The second threaded hole 41 is used to cooperate with a fastener to fix the transmission member 4 on the fixing frame 2. The connection mechanisms in adjacent track grooves 3 are transmitted through the transmission member 4.

[0072] In this embodiment, the transmission member 4 can be fixed to the fixing frame 2 by fasteners, or can slide relative to the guide groove 21 to adjust different positions. This design provides higher flexibility. The user can choose to firmly fix it by fasteners, or adjust the fasteners and adjust the position by sliding relative to the guide groove 21 to meet different curtain configurations and usage requirements.

[0073] Specifically, the curtain sliding device is driven by the motor 5, the motor 5 rotates to drive the synchronous belt, and then drives the first connecting block 11, so as to realize the folding and opening of the curtain, wherein two sets of connecting mechanisms are arranged in the same track groove 3, the connecting mechanisms in the same track groove 3 are driven by the first connecting block 11 and the second connecting block 12, and the connecting mechanisms in adjacent track grooves 3 are driven by the transmission member 4;

[0074] In this embodiment, the quick-release assembly 1 makes it easier to install and remove the two connection blocks. The design of the limiting hole 113 and the limiting connection portion 115 ensures that the two connection blocks are stably fixed after installation, preventing accidental detachment. The design of the fixing frame 2 and the guide groove 21 makes the curtain sliding process smoother. The transmission member 4 enables the connection mechanisms in the multiple track grooves 3 to move in coordination, ensuring the consistency of the overall movement of the curtain.
