Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to fig. 1-4;

the magnetic control lock catch can be applied to any rope which needs to be locked and fixed at two ends, and in the embodiment, the magnetic control lock catch is applied to a restraint belt to carry out protective restraint on a patient; the lock comprises a lock body 1 and a lock tongue 2, wherein the lock body 1 and the lock tongue 2 are respectively fixed at two ends of a restraint strap, and the use mode is that the lock tongue 2 is inserted into the lock body 1, and the restraint strap is closed loop to achieve the restraint effect on a patient;

further describing the action process, in the normal state in the shell 11, the elastic component 12 is kept in a clamped state with the gear component 13, when the lock tongue 2 is inserted from the locking part 14, along with the fact that the positioning hole 21 on the lock tongue 2 is clamped with the ratchet 133 at different positions on the gear component 13 alternately, the gear component 13 rotates, because the elastic component 12 has a reset function, the elastic component 12 is continuously jacked up by the ratchet 133 to realize a continuous clamped-jacked-clamped state, when the lock tongue 2 reaches a proper position, the gear component 13 and the elastic component 12 are also in a clamped state, at the moment, the gear component 13 is also inserted into the positioning hole 21 of the lock tongue 2, and when the lock tongue 2 is pulled out in the opposite direction, the ratchet 133 cannot jack the elastic component 12, so that the lock is realized, when the lock tongue 2 needs to be unlocked, the elastic component 12 needs to be adsorbed by using a magnet, so that the elastic component 12 is forcedly separated from the gear component 13, the clamping effect is eliminated, and at the moment, the gear component 13 can rotate freely, so that the lock tongue 2 can be pulled out;

in summary, compared with the traditional magnetic control lock catch, the magnetic control lock catch is more convenient and simpler to use, does not need to be unlocked and entered by a magnet, and saves operation steps and time.

The present embodiment describes the gear assembly 13;

when the lock tongue 2 is inserted from the locking part 14, the ratchet 133 located at the left side of the gear body 132 jacks up one end of the elastic component 12, the gear body 132 is supported by the first rotating shaft 131, at this time, the lock tongue 2 is inserted without obstruction, the lock tongue 2 is forcibly pulled out from the locking part 14, the gear body 132 needs to rotate clockwise, at this time, the ratchet 133 clamped with the elastic component 12 on the gear body 132 cannot jack up the elastic component 12, and the other ratchet 133 of the gear body 132 is inserted into the positioning hole 21 of the lock tongue 2, so that the lock tongue cannot be forcibly pulled out from the locking part 14; when unlocking is needed, the magnet is used for adsorbing the elastic component 12, so that the elastic component moves upwards to be separated from the gear body 132, the gear body 132 rotates without barriers and can rotate clockwise, and the lock tongue 2 can be pulled out;

in addition, since the lock tongue 2 is inserted into the locking portion 14 and is clamped with the ratchet 133 on the gear body 132, the previous positioning hole 21 is separated from the ratchet 133 along with the entering of the lock tongue 2, and the next positioning hole 21 is combined with the next ratchet 133, so that the gear body 132 can be pushed to rotate and lock, no matter locking or pushing is performed, one ratchet 133 is always arranged in the positioning hole 21, and in the state that no magnet is used for unlocking, if a sheet-shaped object is inserted from the locking portion 14, the positioning hole 21 behind the lock tongue 2 is blocked, the ratchet 133 cannot enter the positioning hole 21 behind, so that the lock tongue 2 cannot be pushed, and meanwhile, the lock tongue cannot be pulled out, and the potential safety hazard in the background technology can be effectively solved by adopting the way that the gear body 132 rotates and locks.

There are various embodiments of the elastic assembly 12, and two embodiments will now be chosen for illustration;

a first embodiment of the elastic assembly 12, see fig. 3;

one end of the metal elastic sheet 121 is rotatably arranged at the left side in the shell 11 through the second rotating shaft 122, the other end of the metal elastic sheet 121 is propped against the ratchet 133 on the gear body 132, a reset piece 123 is arranged between the metal elastic sheet 121 and the second rotating shaft 122, pressure is continuously applied to the metal elastic sheet 121 through the reset piece 123, the metal elastic sheet 121 is always kept in a propped state against the ratchet 133 under the condition that no external force exists, wherein the reset piece 123 can be a torsion spring, one end of the torsion spring is propped against the inner wall of the shell 11, and the other end of the torsion spring is propped against the surface of the metal elastic sheet 121;

when the locking device is used, the lock tongue 2 is inserted into the locking part 14, so that the gear body 132 rotates anticlockwise, namely the left ratchet 133 pushes the metal spring 121 open to the right, the metal spring 121 abuts against the next ratchet 133 under the action of the reset piece 123, the lock tongue 2 can be put into a proper position through such circulation, and when the metal spring 121 abuts against the ratchet 133, the gear body 132 cannot rotate clockwise, so that locking is realized.

A second embodiment of the elastic assembly 12, see fig. 4;

one end of the metal spring 121 is rotatably arranged on the right side in the shell 11 through the second rotating shaft 122, the ratchet 133 on the gear body 132 can enter the clamping hole 1211 on the metal spring 121 to realize the clamping with the metal spring 121 and the gear body 132, a reset piece 123 is arranged between the metal spring 121 and the second rotating shaft 122, the reset piece 123 continuously applies pressure to the metal spring 121, and the metal spring 121 always keeps the clamping state with the gear body 132 under the condition that no external force exists, wherein the reset piece 123 can be a torsion spring, one end of the torsion spring is propped against the inner wall of the shell 11, and the other end of the torsion spring is propped against the surface of the metal spring 121;

when the locking device is used, the lock tongue 2 is inserted into the locking part 14, the gear body 132 rotates anticlockwise, namely the left ratchet 133 jacks up the metal elastic sheet 121, the metal elastic sheet 121 is pressed downwards under the action of the reset piece 123, the ratchet 133 jack up the metal elastic sheet 121 enters the clamping position again, the lock tongue 2 can be put into a proper position through circulation, the ratchet 133 is positioned in the clamping position, and the gear body 132 cannot rotate clockwise, so that locking is realized.

The present embodiment describes the locking portion 14;

the base 141 of the locking part 14 may be an independent component, and may be connected to the housing 11 by welding or the like, or may be integrally formed with the housing 11, an insertion groove 142 is provided in the base 141 along the rotation direction of the gear body 132, a through hole 143 is provided above the insertion groove 142, the ratchet 133 may be rotated into the insertion groove 142 through the through hole 143,

in addition, install the lock body 1 on restraint band M through the installation foot 144 cooperation installation component 3 of establishing at the base 141 side, but the locking only establishes at the side of base 141, restraint band M is the position that is located the base 141 bottom below and is unstressed and can't fix, damage easily under the inhomogeneous circumstances of long-term pulling atress, consequently, through forming the position 145 of keeping away in the base 141 bottom, restraint band M that installation component 3 just can be located the base 141 below like this forms middle part atress point 31, thereby make whole atress even, increase the durability, do not influence the use of lock body 1 simultaneously.
