[0023] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further details the utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0024] Refer to Figures 1-4 , a cordless fitting for a hollow louver, comprising an outer shell 1, characterized in that a sealed door 2 is rotatably connected to an outer wall on one side of the outer shell 1, a cross bar 4 is horizontally arranged in the inner cavity of the outer shell 1, a wire reel 8 is sleeved on an outer ring on one side of the cross bar 4, one end of the cross bar 4 penetrates through an adjacent side wall of the outer shell 1 and extends to one side of the outer shell 1, and the other end of the cross bar 4 is rotatably connected to an inner side wall of the adjacent outer shell 1;
[0025] A hollow tube 5 is provided at the top of the outer shell 1. The bottom of the hollow tube 5 passes through the top of the outer shell 1 through a bushing and extends into the inner cavity of the outer shell 1. A number of soft brushes 6 are fixedly connected to the inner cavity of the hollow tube 5. Specifically, when in use, a person can pass a wire through the inner cavity of the hollow tube 5 and wind it around the outer ring of the wire reel 8. When the person drives the cross bar 4 to rotate through the handle 3, no matter whether the person rotates forward or backward, the wire will always make physical contact with the soft brush 6 inside the hollow tube 5. During the rotation of the cross bar 4, the first bevel gear 7 is driven to rotate, so that the second bevel gear 10 rotates, thereby driving the straight rod 9 and the small pulley 11 to rotate. Through the transmission of the belt 13, the large pulley 12 drives the hollow tube 5 to rotate, giving the soft brush 6 the power to rotate, strengthening the cleaning of the surface of the passing wire. Through the structural design, when the person operates the blind, it helps to quickly clean the floating dust in the air adsorbed on the surface of the wire exposed to the air, and the cleaning operation does not require additional control. Instead, the cleaning operation can be completed during the process of the person controlling the winding and unwinding of the wire, reducing the operation steps of personnel maintenance, improving the use quality of the wire, and preventing the situation where sundries and dust are wound on the outer surface of the anti-seepage wire reel 8.
[0026] This solution has the following working process:
[0027] When in use, a person can pass a wire through the inner cavity of the hollow tube 5 and wind it around the outer ring of the wire reel 8. When the person drives the cross bar 4 to rotate through the handle 3, no matter whether the person rotates forward or backward, the wire will always make physical contact with the soft brush 6 inside the hollow tube 5. During the rotation of the cross bar 4, the first bevel gear 7 is driven to rotate, so that the second bevel gear 10 rotates, thereby driving the straight rod 9 and the small pulley 11 to rotate. Through the transmission of the belt 13, the large pulley 12 drives the hollow tube 5 to rotate, giving the soft brush 6 the power to rotate, strengthening the cleaning of the surface of the passing wire.
[0028] According to the above working process, it can be known that:
[0029] Through the structural design, when the person operates the blind, it helps to quickly clean the floating dust in the air adsorbed on the surface of the wire exposed to the air, and the cleaning operation does not require additional control. Instead, the cleaning operation can be completed during the process of the person controlling the winding and unwinding of the wire, reducing the operation steps of personnel maintenance, improving the use quality of the wire, and preventing the situation where sundries and dust are wound on the outer surface of the anti-seepage wire reel 8.
[0030] Further, one side of the outer ring of the cross bar 4 is fixedly connected with a first bevel gear 7. One side of the first bevel gear 7 is meshed and connected with a second bevel gear 10 through engaging teeth. The top of the second bevel gear 10 is fixedly connected with a straight rod 9. The top of the straight rod 9 passes through the top of the inner cavity of the housing 1 through a bushing and extends to the top of the housing 1. Specifically, through the setting of the housing 1, the internal structure thereof is protected from external forces.
[0031] Further, a large pulley 12 is sleeved on the upper part of the outer ring of the hollow tube 5. The extended end of the straight rod 9 is fixedly connected with a small pulley 11. The large pulley 12 and the small pulley 11 are wound and connected by a belt 13. Specifically, through the setting of the belt 13, the small pulley 11 can be connected and driven with the large pulley 12.
[0032] Further, one end of the cross bar 4 is rotatably connected with the inner side wall of the adjacent housing 1 through a rotating shaft. Specifically, through the setting of the cross bar 4, stable support is provided for the wire reel 8 and the first bevel gear 7.
[0033] Further, the extended end of the cross bar 4 away from the housing 1 is fixedly connected with a grip 3. Specifically, through the setting of the grip 3, the anti-slip ability of the cross bar 4 is increased.
[0034] Further, the wire reel 8 is located directly below the hollow tube 5. Specifically, through the setting of the wire reel 8, it is convenient for personnel to wind and unwind the wire.
[0035] In summary: When in use, a person can pass the wire through the inner cavity of the hollow tube 5 and wind it around the outer ring of the wire reel 8. When the person drives the cross bar 4 to rotate through the grip 3, regardless of whether the person rotates it forward or backward, the wire will always make physical contact with the soft brush 6 inside the hollow tube 5. During the rotation of the cross bar 4, the first bevel gear 7 is driven to rotate, which causes the second bevel gear 10 to rotate, thereby driving the straight rod 9 and the small pulley 11 to rotate. Through the transmission of the belt 13, the large pulley 12 drives the hollow tube 5 to rotate, providing the soft brush 6 with the power to rotate, strengthening the cleaning of the surface of the passing wire. Through the setting of the outer shell 1, the internal structure is protected from external forces. Through the setting of the belt 13, the small pulley 11 can be connected and driven with the large pulley 12. Through the setting of the cross bar 4, stable support is provided for the wire reel 8 and the first bevel gear 7. Through the setting of the grip 3, the anti-slip ability of the cross bar 4 is increased. Through the setting of the wire reel 8, it is convenient for a person to take in and release the wire. Through the structural design, when a person operates the blind, it helps to quickly clean the floating dust adsorbed on the surface of the wire exposed to the air, and the cleaning operation does not require additional control. Instead, the cleaning operation can be completed during the process of the person controlling the taking in and releasing of the wire, reducing the maintenance operation steps of the person while improving the quality of wire use and preventing the situation where sundries and dust are wound around the outer surface of the anti-seepage wire reel 8.
