Description
Technical field
The present invention relates to seat part fields, more particularly, to a kind of limit rotary shaft of swiveling seat.
Background technique
General market rotatable seat can be rotated arbitrarily, can be unrestricted with infinite rotational circle number along a direction.
But when leisure chaise longue has electric functions, seat needs wiring energization driving, long if there is no limit slewing areas for seat rotation
Phase ceaselessly rotates, and will easily cause wire intertwist together, so that wiring be pulled to cause, attaching plug is loosened or wiring is electric
Thread breakage causes danger.
Publication No. " CN107693294A " discloses a kind of rotation-limited structure of dental chair bracket, the patent institute
The limiting slot of disclosed rotation-limited structure and the structure of limited block are exposed to outside, are easily accessible dust impurity, when use
Between it is long long afterwards, cause rotation increased friction, influence rotation effect.
Summary of the invention
The present invention in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of limit rotary shaft, for limiting
Structure be placed in inside, avoiding dust impurity influences the rotation of position limiting structure, extends and uses the time.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of limit rotary shaft of swiveling seat, packet
Include the limit fixed block of central spindle, hollow shaft housing and limitation central spindle rotational angle in the hollow shaft housing, the central spindle peace
Loaded in the hollow shaft housing；The hollow shaft housing inner cavity is equipped with spacing block set, and the limit fixed block fixes the central spindle
It is abutted against in the hollow shaft housing and with the spacing block set.
Central spindle and limit fixed block rotate in hollow shaft housing, and after turning an angle to a direction, limit is fixed
Block is contacted with spacing block set, cannot continue to rotate after reaching the limit of position.
Preferably, described central spindle one end is provided with mounting head, and the outer diameter of the mounting head is greater than the interior of the hollow shaft housing
Diameter.Mounting head cannot pass through hollow shaft housing, and central spindle is avoided to move down across hollow shaft housing.
Preferably, the hollow shaft housing far from the mounting head one end be equipped with stepped hole, the limit fixed block and
The shoulder of the stepped hole is bonded and is fixedly connected with the central spindle.Limit fixed block is placed in the bigger stepped hole of diameter,
The installation of more convenient central spindle is fixed.
Preferably, the limit fixed block is fixedly connected by two fixing bolts with the central spindle.Limit is reduced to fix
The freedom degree connected between block and central spindle prevents central spindle relative to limit fixed block rotation.
Preferably, between the mounting head and the hollow shaft housing and the hollow shaft housing and the limit fixed block it
Between be respectively arranged with the rubber sleeve.Rubber sleeve plays the role of buffering, more steady and smooth when mechanism kinematic.
Preferably, gasket is housed between the mounting head and the rubber sleeve.
Preferably, the side of the limit fixed block is provided with protrusion, the edge phase of the protrusion and the spacing block set
It abuts.The side of protrusion is inclined-plane, and after contacting with spacing block set, the impact force being subject to will be separated into direction of motion stress and hang down
Directly in the stress of contact position, and then the stress of the direction of motion is reduced, reduces the strength of rebound.
Preferably, the limit fixed block is equipped with semiorbicular limiting groove, and it is recessed that the spacing block set protrudes into the limit
In slot, and moved in the limiting groove.Spacing block set moves in limiting groove, and spacing block set is difficult to limit fixed block
It loosens.
Preferably, the spacing block set is standard fasteners, and the hollow shaft housing is provided with tight for installing the standard
The mounting hole of firmware.Standard fasteners can be fixed screw, fixing bolt or fixed bolt, preferably fixed screw, limit
It can be worn after the long-time use of convex block, the use of fixed screw be spacing block set, can be convenient for changing after wearing.
Preferably, the end of the mounting head and the hollow shaft housing are led far from being equipped on the outside of described mounting head one end
Enter oblique angle.Oblique angle facilitates mounting head and hollow shaft housing to be connected with the other component of seat.
Compared with prior art, beneficial effect is: limit rotary shaft of the invention being inserted into seat base, then by entire seat
Chair rack sleeve is inserted into mounting head, so that it may complete installation, structure is simple, installation convenience；By adjusting the big of limit fixed block
Angle small, that setting central spindle can rotate；Steady and smooth is noiseless during the motion for limit rotary shaft, will not generate abnormal sound bounce
Phenomena such as with fracture, durability is more permanent.
