A motor shaft of the speed reducing motor is provided with a cam 5, a bulge on one side of the cam is abutted against a column part 1001 at one end of the latch, the outer diameter of the other end of the latch is provided with a contact rib 1002, the contact rib of the latch triggers a contact plate of a motor detection switch through the rotation of the latch, a steel wire rope in a base is wound on a ratchet wheel and is collected in a wire drawing box, and one end of the column part of the latch is abutted against one-way teeth at the outer diameter of the ratchet wheel; the bolt, gear motor, motor detection switch, ratchet and pull wire box are fixed and are set up the recess that corresponds in the base, and the centre of bolt is fixed in the base and swings in, and protruding one side of cam is equipped with torsional spring 4, and the one end of torsional spring offsets with the post department torsional spring groove of bolt, and the other end of torsional spring offsets with the inner wall of base, and the circuit board is equipped with bluetooth module and signal transceiver module, and motor detection switch, gear motor and battery pass through the circuit and are connected with the circuit board.
The concrete structure is as follows: one side of the ratchet wheel is provided with a wheel part with a diameter larger than that of the ratchet wheel, the outer diameter of the wheel part of the ratchet wheel is provided with unidirectional teeth which are uniformly distributed, the other side of the ratchet wheel is sleeved and fixed in a rubber pad 15, the ratchet wheel is sleeved and connected with a flat key wall corresponding to a central hole in the rubber pad into a whole through flat key grooves which are equidistantly distributed on the cylindrical surfaces between the two sides, the central hole of the ratchet wheel is inserted into a shaft core part in a base, when a steel wire rope is pulled out of the pull-line box, an end angle of one side between a swinging point and a column part of a latch is meshed with the unidirectional teeth of the ratchet wheel, and the steel wire rope in the base is wound on a wire groove of the rubber pad with the outer diameter of the ratchet wheel. The main part of the bolt is a plate, one end of the column part of the bolt is bent towards the extending side of the steel wire rope, the column part is positioned on one side of the end part of the bolt, the column part of the bolt is arranged in the base and is abutted against the bulge of the cam, the end angle of one side of the bolt is positioned on one side of the ratchet wheel of the bent part, and the width of the contact rib at the other end of the bolt is smaller than that of the column part of the swing point. The gear motor is arranged on the inner wall of one side of the extending part of the steel wire rope of the base, a motor shaft of the gear motor and the steel wire rope are vertically distributed, and the latch is arranged on one side of the upper cover above the gear motor. The outer diameter of the base at the extending part of the steel wire rope of the base is provided with a stop block 2, one side of the stop block of the steel wire rope in the base is provided with a fixing sleeve, a contact plate which is tilted at one side of the lock closing detection switch is abutted to the outer diameter of the hole opening at the steel wire rope position of the stop block in the base, the fixing sleeve of the steel wire rope is taken in the base through the stop block and triggers the contact plate of the lock closing detection switch, and the stop block of the steel wire rope is limited to the outer diameter of the hole position of the steel wire rope position of the base. The dog includes left dog and right dog, and wire rope's fixed cover department is equipped with the fixed block, and when the fixed block of wire rope was held tightly in the meshing department of left dog and right dog, left dog was even as an organic whole with right fender through pin 3 of both sides.
The steel wire rope of the lock always has tightening force due to the spiral spring inside the pull line box, the steel wire rope of the lock is in a tightening state under a normal state, and the lock is limited by the stop block fixed on the steel wire rope and stops at the outer side of the base. Under the state of locking, the ratchet wheel assembly makes the ratchet wheel assembly unable to rotate because the latch card makes in the one-way tooth of ratchet wheel assembly, when the manpower removes to draw wire rope, because wire rope winds in the rubber pad outside of ratchet wheel assembly, has huge frictional force for can't take place relative motion between wire rope and the rubber pad, thereby the principle of application this frictional force realizes that wire rope locks can't be pulled out. During unlocking, the cam on the speed reducing motor drives the bolt to enable the bolt to be separated from the one-way teeth of the ratchet wheel assembly, and after the bolt touches the motor detection switch, the speed reducing motor stops operating, so that unlocking is completed. When locking, the cam resets due to the reverse rotation of the speed reducing motor, stops when the cam rotates to the locked position, and the bolt resets under the action of the torsion spring and is clamped on the one-way teeth of the ratchet wheel assembly to realize locking. When the steel wire rope is pulled out, the lockset cannot be pulled out continuously after being locked, but the steel wire rope can be continuously withdrawn by the pull line box because the one-way teeth in the ratchet wheel assembly can only be locked in one direction. When the steel wire rope retracts to a certain length, the stop block of the steel wire rope touches the lock closing detection switch, and the in-place information report of the lock position is realized.
In conclusion, this tool to lock relates to intelligent bluetooth lock, is that it has the bluetooth mode to authorize, realizes the tool to lock of wire rope pull through the unblock ratchet after the mandate. The lockset controls the take-up and the pull of the steel wire rope by utilizing the take-up function of the pull wire box and the ratchet wheel assembly, and realizes the unlocking and the locking of the ratchet wheel assembly by matching with the gear motor and the cam, thereby realizing the control of the pull and the pull of the unlocking steel wire rope and the automatic take-up of the steel wire rope. Namely, one end of the lockset is a rope ring, the other end of the lockset is an electronic lock, one end of the rope ring is fixed on the base of the accompanying chair, and the other end of the rope ring is fixed below the chair surface of the accompanying chair for movable extension. When the chair is locked, the steel wire rope cannot be drawn out of the lockset, so that the accompanying chair cannot be unfolded from a folded state; after the unlocking is authorized, the steel wire rope is drawn out from the lockset to realize the unfolding of the accompanying chair; returning the accompanying chair after the user uses up, the user packs up the chair, and the wire rope of this board tool to lock is pulled back by the terminal box to this in-process wire rope can only be withdrawed, can't pull open, thereby solve instant chair and rock the problem that the clearance is big, also can ensure to lock. The lockset can be used on a nursing chair and can also be applied to the field of various industries needing to use a steel wire rope for locking.
