Description

Technical Field

[0001] This utility model relates to the field of Venetian blinds, and in particular to a self-resetting Venetian blind dimming rod structure that prevents hand pinching. Background Technology

[0002] Venetian blinds are a type of window covering that controls light, ventilation, and privacy through adjustable slat angles. The core concept lies in the combination of functional flexibility and spatial adaptability. They consist of multiple parallel slats and a drive system. Users can rotate the slats by pulling cords, dimmer bars, or electric devices to achieve stepless adjustment from fully closed to fully open.

[0003] When staff rotate the dimmer bar to close the blinds, bystanders may try to adjust the angle of the slats through the gaps, or children may curiously reach out and touch the slats without being noticed. This can easily cause the dimmer bar to rotate and close the blinds, trapping fingers and causing injury, thus reducing the safety of use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-resetting anti-pinch venetian blind dimming rod structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-resetting anti-pinch venetian blind dimming rod structure, comprising a first dimming rod, one end of which is fixedly connected to an anti-slip handle, a protective component being provided at the end of the first dimming rod away from the anti-slip handle, a second dimming rod being provided on one side of the protective component, a connector being fixedly connected to the side of the second dimming rod away from the protective component, and a disassembly component being provided inside the protective component.

[0006] Furthermore, the protective component includes a connecting sleeve threadedly connected to the side of the first dimming bar away from the anti-slip handle, and the side of the connecting sleeve away from the first dimming bar is rotatably connected to the second dimming bar.

[0007] Furthermore, the protective structure also includes a first mounting ring, which is disposed on the opposite side of the first dimming bar and the second dimming bar, and is disposed inside the connecting sleeve. A second mounting ring is disposed on one side of the first mounting ring.

[0008] Furthermore, a first connecting seat and a second connecting seat are rotatably connected to both sides of the first mounting ring and the second mounting ring, respectively, and a torsion spring is provided on the opposite side of the first connecting seat and the second connecting seat.

[0009] Furthermore, the disassembly assembly includes connecting blocks and connecting grooves. The connecting blocks are equidistantly arranged and fixedly connected to one end of the second mounting ring near the first mounting ring. The connecting grooves are equidistantly arranged and opened on one side of the first mounting ring near the second mounting ring. The connecting blocks are engaged with each other, and the first mounting ring and the second mounting ring form a cylindrical shape through the engagement of the connecting blocks and connecting grooves.

[0010] Furthermore, the first mounting ring has four threaded fixing bolts at its four corners near the connecting groove, and the fixing bolts pass through the connecting block and the connecting groove and are threadedly connected to the connecting block.

[0011] Furthermore, the disassembly assembly also includes a locking block, which is fixedly connected to both ends of the torsion spring and engages with the second connecting seat and the second connecting seat. A fixing bolt is threadedly connected to the middle of the locking block, and the fixing bolt is threadedly connected to the first connecting seat and the second connecting seat.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a protective component, when the anti-slip handle is gripped and rotated, the first dimming rod drives the first connecting seat to rotate on the first and second mounting rings. The locking block connected to one end of the first connecting seat drives the torsion spring to rotate under the rotation of the first connecting seat. The torsion spring drives the second dimming rod on one side of the second connecting seat to rotate on one side of the connecting sleeve, adjusting the blades. When the user's finger is placed in the blades, the rotation of the second dimming rod generates resistance. The torsion spring deforms after encountering resistance. Therefore, the force generated by the continuous rotation of the first dimming rod is offset by the torque generated by the deformation of the torsion spring, thereby further cushioning and protecting the finger and preventing the finger from being pinched. When the force on the first dimming rod stops, the torque generated by the torsion spring disappears as the force on the first dimming rod stops, causing the torsion spring to rebound and drive the first dimming rod to reset, facilitating subsequent use.

[0014] 2. In this utility model, by setting up a disassembly component, when the torsion spring needs to be replaced, the fixing bolt is removed from the connecting block and the connecting groove, the connection between the connecting block and the connecting groove is released, the second mounting ring is held and pulled, the connecting block is moved out of the connecting groove with the second mounting ring, so that the torsion spring is exposed to the environment, the fixing bolt is removed from the first connecting seat and the second connecting seat, the fixing of the locking block is released, and the locking block is removed from the first connecting seat and the second connecting seat, which facilitates the replacement of the torsion spring.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a self-resetting anti-pinch venetian blind dimming rod structure, including a first dimming rod 1, one end of the first dimming rod 1 is fixedly connected to an anti-slip handle 11, a protective component is provided at the end of the first dimming rod 1 away from the anti-slip handle 11, a second dimming rod 2 is provided on one side of the protective component, a connector 21 is fixedly connected to the side of the second dimming rod 2 away from the protective component, and a disassembly component is provided inside the protective component.

[0023] Please see Figure 2 and Figure 3 The protective component includes a connecting sleeve 3, which is threaded to the side of the first dimming rod 1 away from the anti-slip handle 11, and the side of the connecting sleeve 3 away from the first dimming rod 1 is rotatably connected to the second dimming rod 2. The protective structure also includes a first mounting ring 31, which is disposed on the opposite side of the first dimming rod 1 and the second dimming rod 2, and is disposed inside the connecting sleeve 3. A second mounting ring 33 is disposed on one side of the first mounting ring 31. A first connecting seat 34 and a second connecting seat 35 are rotatably connected to the two sides of the first mounting ring 31 and the second mounting ring 33, respectively. A torsion spring 32 is disposed on the opposite side of the first connecting seat 34 and the second connecting seat 35.

[0024] In this embodiment, when the anti-slip handle 11 is gripped and rotated, the first dimming rod 1 rotates, causing the first connecting seat 34 to rotate on the first mounting ring 31 and the second mounting ring 33. The locking block 43 connected to one end of the first connecting seat 34 rotates, causing the torsion spring 32 to rotate. The torsion spring 32 causes the second dimming rod 2 on one side of the second connecting seat 35 to rotate on one side of the connecting sleeve 3, adjusting the blades. When the user's finger is placed in the blades, the rotation of the second dimming rod 2 generates resistance. The torsion spring 32 deforms after encountering resistance. Therefore, the force generated by the continuous rotation of the first dimming rod 1 is offset by the torque generated by the deformation of the torsion spring 32, thereby further cushioning and protecting the finger and preventing the finger from being pinched. When the force on the first dimming rod 1 stops, the torque generated by the torsion spring 32 disappears as the force on the first dimming rod 1 stops, causing the torsion spring 32 to rebound and move the first dimming rod 1 back to the initial angle for easy subsequent use.

[0025] Please see Figure 4 and Figure 5 The disassembly assembly includes connecting blocks 4 and connecting grooves 41. The connecting blocks 4 are equidistantly arranged and fixedly connected to one end of the second mounting ring 33 near the first mounting ring 31. The connecting grooves 41 are equidistantly arranged and opened on one side of the first mounting ring 31 near the second mounting ring 33. The connecting blocks 4 are engaged with each other. The first mounting ring 31 and the second mounting ring 33 form a cylinder through the engagement of the connecting blocks 4 and the connecting grooves 41. The four corners of the first mounting ring 31 near the connecting grooves 41 are threaded with fixing bolts 42. The fixing bolts 42 pass through the connecting blocks 4 and the connecting grooves 41 and are threadedly connected to the connecting blocks 4. The disassembly assembly also includes a locking block 43. The locking block 43 is fixedly connected to both ends of the torsion spring 32. The locking block 43 is engaged with the second connecting seat 35. The middle of the locking block 43 is threaded with a fixing bolt 44. The fixing bolt 44 is threadedly connected to the first connecting seat 34 and the second connecting seat 35.

[0026] In this embodiment, when the torsion spring 32 needs to be replaced, the fixing bolt 42 is removed from the connecting block 4 and the connecting groove 41, the connection between the connecting block 4 and the connecting groove 41 is released, the second mounting ring 33 is held and pulled, the connecting block 4 is moved out of the connecting groove 41 as the second mounting ring 33 is pulled, so that the torsion spring 32 is exposed to the environment, the fixing bolt 44 is removed from the first connecting seat 34 and the second connecting seat 35, the fixing of the locking block 43 is released, and the locking block 43 is removed from the first connecting seat 34 and the second connecting seat 35, so that the torsion spring 32 can be replaced.

[0027] Working principle: First, hold the anti-slip handle 11 and rotate it. The rotation of the anti-slip handle 11 drives the first connecting seat 34 to rotate on the first mounting ring 31 and the second mounting ring 33. The locking block 43 connected to one end of the first connecting seat 34 drives the torsion spring 32 to rotate under the rotation of the first connecting seat 34. The torsion spring 32 drives the second dimming rod 2 on one side of the second connecting seat 35 to rotate on one side of the connecting sleeve 3 to adjust the blade. When the user's finger is put into the blade, the rotation of the second dimming rod 2 generates resistance. The torsion spring 32 deforms after being resisted. Therefore, the force generated by the continuous rotation of the first dimming rod 1 is canceled by the torque generated by the deformation of the torsion spring 32, thereby further cushioning and protecting the finger and preventing the finger from being pinched. When the force on the first dimming rod 1 stops, the torque generated by the torsion spring 32 disappears as the force on the first dimming rod 1 stops, causing the torsion spring 32 to rebound and drive the first dimming rod 1 to move back to the initial angle for easy subsequent use.

[0028] Next, when the torsion spring 32 needs to be replaced, remove the fixing bolt 42 from the connecting block 4 and the connecting groove 41 to release the connection between the connecting block 4 and the connecting groove 41. Hold the second mounting ring 33 and pull it. The connecting block 4 will move out of the connecting groove 41 as the second mounting ring 33 is pulled, exposing the torsion spring 32 to the environment. Remove the fixing bolt 44 from the first connecting seat 34 and the second connecting seat 35 to release the fixing of the locking block 43. Remove the locking block 43 from the first connecting seat 34 and the second connecting seat 35 to facilitate the replacement of the torsion spring 32.
