Door slider with V-shaped transmission structure

Abstract

The invention discloses a door slider. The door slider comprises a rotating wheel arranged on a drive device and a moving bar arranged on a door, wherein the drive device is used for driving the rotating wheel to rotate; and the rotating wheel and the moving bar realize connection through the matching between a groove and a bulge and then realize reciprocating motion of the moving bar. A transmission structure carries out power transmission through the groove and a structure matched with the groove, thus a transmission surface between the groove and the structure is expanded, then the maximum transmission force is increased, and finally the maximum transmission force between the groove and the structure is increased. Therefore, the transmission structure is capable of transmitting a heavier door without a slip phenomenon.

Description

technical field [0001] The invention belongs to the field of accessories for moving doors, in particular to a door moving device for moving doors with a V-shaped transmission structure. Background technique [0002] The use of induction doors is very common, and it also brings a lot of convenience to people's lives. At present, most of the sensor doors use sliding doors. When a moving object approaches the sliding door, the sliding door will open to both sides (linear motion, not rotation). It is mainly realized in the following two forms: [0003] Such as figure 1 and 2 The shown door shifter adopts the form of cooperation between the plane wheel 12 and the plane bar 13. The motor 11 drives the plane wheel 12 to rotate, and the plane wheel 12 drives the plane bar 13 to move back and forth to realize the opening and closing of the door. When the door is heavy, it is prone to slippage, which may eventually prevent the door from closing or opening. [0004] Such as imag...

Problems solved by technology

[0003] like figure 1 and 2 The shown door shifter adopts the form of cooperation between the plane wheel 12 and the plane bar 13. The motor 11 drives the plane wheel 12 to rotate, and the plane wheel 12 drives the plane bar 13 to move back and forth to realize the opening and closing of the door. When the door is heavy, it is prone to slipping, which may eventually prevent the door from closing or opening

[0004] like image 3 and 4 The shown door shifter adopts the gear 22 and the gear rack 23 in the form of cooperation. The motor 21 drives the gear 22 to rotate, and the gear 22 drives the rack 23 to move back and forth, thereby realizing the opening or closing of the door. The engagement of the rack 23 makes it extremely noisy, and it is difficult to open or close the door manually during a power outage
