Electric pet toy
View Patent ↗An electric pet toy is provided, which includes a main unit, a rope, and a fixing device. The main unit includes a shell, a driving motor, and a roller. The driving motor is fixed on the shell. The roller includes a center shaft and side walls that are oppositely arranged on two sides of the center shaft. The center shaft is connected to an output shaft of the driving motor. When working, the driving motor can drive the roller to rotate clockwise or counterclockwise. One end of the rope is connected to the roller, and another end is connected with an ornament. The rope can be wound on the center shaft under the rotation of the roller, to drive the ornament to do reciprocating movement in a vertical direction.
1 . An electric pet toy, comprising:
a main unit, comprising a shell, a driving motor, and a roller, wherein the driving motor is fixed on the shell; the roller comprises a center shaft and side walls that are oppositely arranged on two sides of the center shaft; the center shaft is connected to an output shaft of the driving motor; when working, the driving motor drives the roller to rotate clockwise or counterclockwise;
a rope, wherein one end of the rope is connected to the roller, and another end is connected with an ornament; the rope is wound on the center shaft under the rotation of the roller, to drive the ornament to do reciprocating movement in a vertical direction; and
a fixing device, wherein one end of the fixing device is connected to the shell, and another end is detachably connected to a target object, so that when the main unit is connected to the target object, the center shaft of the roller is in a horizontal direction;
wherein the fixing device comprises two oppositely arranged clamping arms; each of the two clamping arms comprises a fixing end and a clamping end; the two fixing ends are in shaft connection to the shell, to cause the two clamping arms to rotate around the fixing ends; torsion springs are further arranged at the two fixing ends, to generate an elastic clamping force between the two clamping arms; and the clamping ends extend to an outside of the shell to clamp the target object.
2 . The electric pet toy according to claim 1 , wherein the fixing ends of the two clamping arms are of gear structures; the two gear structures are meshed with each other; and the two gear structures pass through axes of gears via fixing screws and are fixed to the shell.
3 . The electric pet toy according to claim 2 , wherein the clamping ends are connected with clamping lugs; and the clamping lugs are provided with nonslip pads.
4 . The electric pet toy according to claim 3 , wherein the fixing device comprises at least one suction cup; the suction cup is arranged in the horizontal direction or the vertical direction to be sucked to a surface of the target object in different directions.
5 . The electric pet toy according to claim 4 , wherein the shell further comprises a baffle plate; and the baffle plate is close to the roller and is arranged in a circumferential direction of outer edges of the two side walls to block an outer side of a portion of the roller.
6 . The electric pet toy according to claim 5 , wherein the rope is made of an elastic material.
7 . The electric pet toy according to claim 1 , wherein the center shaft comprises a shaft hole and a plurality of flanges that extend outwards from the shaft hole in a radial direction, and angles formed between the flanges are the same.
8 . The electric pet toy according to claim 7 , wherein four flanges are comprised, and extension lengths of at least some of the flanges are different.
9 . The electric pet toy according to claim 1 , wherein a bearing is fixed at a tail end of the output shaft, and a cross section of the bearing is larger than a cross section of the output shaft and is rectangular.
