Description
Technical field
This utility model relates to a kind of revolute with quick lock in function, belongs to field of machining.
Background technology
Revolute is the common components that two turning arms carry out one degree of freedom motion, and two turning arms are adjusted by revolute
Whole relative rotation angle realizes front end turning arm near operating position.In actual mechanical process, need to two turning arms it
Between relative rotation angle lock.The latch-up structure of tradition revolute generally uses damping wheel structure or screw lock knot
Structure, the coupling mechanism force of damping wheel structure is less, such as the turning arm rotating operation of the apparatus such as medical operating, damping wheel structure without
Its requirement to the latched position stability of the two turning arm anglecs of rotation of method；And screw lock structure, owing to needs are in rotation every time
Turn, locking time carry out slack adjuster operation, the operating time of the operator of increase and labor intensity, impact operation continuity,
And lock poor stability.
Utility model content
The purpose of this utility model is to solve tradition revolute latch-up structure, has that locking operation is loaded down with trivial details, locking is steady
The shortcomings such as qualitative difference, and a kind of revolute with quick lock in function is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of revolute with quick lock in function of the present utility model, including driving member, driven member, rotating shaft,
Metal sucker, electric magnet, extension spring, electromagnet base；
Driving member is socketed in rotating shaft side fixed with driven member, makes between driving member with driven member relative
Rotating shaft is rotatably connected；Rotating shaft passes the end of driving member one end and is fixed with metal sucker；
Electromagnet base is the cylindrical member of one end open, and electromagnet base tubular inner bottom is fixed with center and has the connection of rectangular opening
Ring, electric magnet rear end is fixed with rectangle connecting rod, and the rectangle connecting rod of electric magnet is inserted electromagnet base and connected the rectangular through-hole of ring
In, and it is connected extension spring between electric magnet with electromagnet base tubular inner bottom；The opening of electromagnet base is fixed with driving member, and electricity
The metal sucker that the electric magnet connected in magnetic receiver and the rotating shaft front end passing driving member are fixed aligns；When electric magnet power-off
Time, electric magnet, under the effect of extension spring, is inserted back in the rectangular through-hole that electromagnet base connects ring, driving member and driven member
Between circumferencial direction freely rotatable；When the solenoid is energized, electric magnet stretches forward magnetic-adsorption between extension spring and metal sucker,
Locked by frictional force circumference between electric magnet and metal sucker, make circumferencial direction locking between driving member and driven member.
Electric magnet is all processed as matsurface with the contact surface of metal sucker, to increase electric magnet and the locking of metal sucker circumference
Frictional force.
Being engaged with the output gear of motor by socket gear outside driving member, motor passes through gear driven driving member
Rotate relative to driven member.
Beneficial effect:
Revolute of the present utility model, simple in construction, easy for installation, reliable lock, the freedom between two pivoted arms can be realized
Rotate and quick locking, meet the operation requirement that turning arm frequently rotates, locks, there is important practical and be worth.

Component 2, rotating shaft 3, metal sucker 4, electric magnet 5, extension spring 6, electromagnet base 7, gear 8, motor 9；
Driving member 1 is socketed in rotating shaft side fixed with driven member 2, makes between driving member 1 and driven member 2
Phase countershaft 3 is rotatably connected；Rotating shaft 3 passes the end of driving member 1 one end and is fixed with metal sucker 4；
Electromagnet base 7 is the cylindrical member of one end open, and electromagnet base 7 tubular inner bottom is fixed with center and has the company of rectangular opening
T-Ring, electric magnet 5 rear end is fixed with rectangle connecting rod, and the rectangle connecting rod of electric magnet 5 is inserted electromagnet base 7 and connected the rectangle of ring
In through hole, and it is connected extension spring 6 between electric magnet 5 with electromagnet base 7 tubular inner bottom；The opening of electromagnet base 7 and driving member 1
Fixing, and the fixing metal sucker 4 of the electric magnet 5 that connects in electromagnet base 7 and rotating shaft 3 front end that passes driving member 1 aligns；
When electric magnet 5 power-off, electric magnet 5, under the effect of extension spring 6, is inserted back in the rectangular through-hole that electromagnet base 7 connects ring, main
Move circumferencial direction between component 1 and driven member 2 freely rotatable；When electric magnet 5 is energized, electric magnet 5 stretch forward extension spring 6 with
Magnetic-adsorption between metal sucker 4, is locked by frictional force circumference between electric magnet 5 and metal sucker 4, make driving member 1 with
Circumferencial direction locking between driven member 2.
