In order to solve above technical matters, the utility model is achieved through the following technical solutions: a kind of bearing circle automatic reset device, comprise steering wheel shaft, base, actuating device, described actuating device is fixed on base, described actuating device driving direction dish rotating shaft rotates, described base is fixed with sleeve pipe, and casing pipe sleeve is connected on steering wheel shaft; Outside of sleeve wall is socketed with torsion spring, and when overlooking, torsion spring wrapped anti-clockwise is on outside of sleeve wall, and torsion spring has upper and lower two ends, and the upper end of torsion spring is bent with right drag hook, and the lower end of torsion spring is bent with Zola's hook, and Zola's hook opening is relative with the opening of right drag hook; Base is fixed with position-limited lever, steering wheel shaft is fixed with pull bar, position-limited lever and pull bar are all between Zola's hook opening and right drag hook.
Further, the diameter of described position-limited lever is greater than the diameter of pull bar, and Zola's hook and right drag hook abut against the both sides of position-limited lever respectively; Abut against fiber rod both sides, still can keep certain elastic force when pull bar torsion spring resets, improve reseting performance.
Further, described actuating device is rotating machine; Structure is simple, is beneficial to manufacture.
Further, described base is fixed on car body, or base and car body are wholely set; Be conducive to improving stability.
Further, described steering wheel shaft is also fixed with location pin; Be convenient to the rotational angle limiting perambulator, ensure safety traffic.
Further, described location pin has two and lays respectively at the both sides of position-limited lever; Can realize limiting perambulator left and right both direction rotational angle.
Further, described steering wheel shaft is made up of disk body and the axis body be fixed on below disk body; Described axis body is plugged in sleeve pipe, and pull bar and location pin are all connected in the lower surface of disk body; Be convenient to install.
Compared with prior art the utility model has the advantages that: control pull bar by torsion spring in the utility model and reset, thus drive steering wheel shaft to reset, the effect of position-limited lever is when torsion spring rotates, one end of torsion spring can be fixed, a position-limited lever can be fixed the two ends of torsion spring respectively, simplifies the structure, reduces manufacturing cost, be convenient to dismounting, be beneficial to maintenance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of steering wheel shaft in the utility model
Detailed description of the invention
Consult Fig. 1, a kind of bearing circle automatic reset device, comprise steering wheel shaft 1, base 2 and actuating device 3, described actuating device 3 is fixed on base 2, described actuating device 3 driving direction dish rotating shaft 1 rotates, and described base 2 is fixed with sleeve pipe 4, and sleeve pipe 4 is socketed on steering wheel shaft 1; Sleeve pipe 4 lateral wall is socketed with torsion spring 5, and when overlooking, torsion spring 5 wrapped anti-clockwise is on sleeve pipe 4 lateral wall, torsion spring 5 has upper and lower two ends, the upper end of torsion spring 5 is bent with right drag hook 61, and the lower end of torsion spring 5 is bent with Zola's hook 62, and Zola's hook 62 opening is relative with the opening of right drag hook 61; Base 2 is fixed with position-limited lever 7, steering wheel shaft 1 is fixed with pull bar 8, position-limited lever 7 and pull bar 8 are all between Zola's hook 62 opening and right drag hook 61.The diameter of described position-limited lever 7 is greater than the diameter of pull bar 8, and Zola's hook 62 and right drag hook 61 abut against the both sides of position-limited lever 7 respectively.Described base 2 is fixed on car body, or base 2 is wholely set with car body, the perambulator car body that car body refers to.
Consult Fig. 2, described steering wheel shaft 1 is made up of disk body 11 and the axis body 12 be fixed on below disk body 11, and disk body 11 and bearing circle body are fixed together or are wholely set; Described axis body 12 is plugged in sleeve pipe 4, and pull bar 8 and location pin 9 are all connected in the lower surface of disk body 11.
Described actuating device 3 is rotating machine, or actuating device 3 is made up of rotating machine and the transmission device that controlled by rotating machine.
Described steering wheel shaft 1 is also fixed with two location pins 9, location pin 9 lays respectively at the both sides of position-limited lever 7.As long as described Zola's hook 62 and right drag hook 61 also can realize the similar structures replacement of catching on pull bar by similar rod member, block etc., be all encompassed within protection domain.
After steering wheel of baby carrier rotates counterclockwise, pull bar 8 drives right drag hook 61 to rotate, and position-limited lever 7 catches on torsion spring 5 Zola hook 61, and now, torsion spring 5 is in tensioning state, and after having turned to, pull bar 7 resets simultaneously under the effect of torsion spring 5, and bearing circle resets.When bearing circle rotates clockwise, principle is identical.
