Please refer to fig. 1-2;

the fixing structure aims to solve the problem that the stress of the restraint strap M is uneven when the lock body is fixed, so that the service life is prolonged;

when in installation, the bottom plate 31 is firstly arranged on one side of the restraint belt M, a plurality of fixing columns 32 penetrate through the restraint belt M and extend to the other side of the restraint belt M, the gasket 33 is arranged on the other side of the restraint belt M, then the fixing columns 32 penetrate through the gasket 33, the restraint belt M is positioned between the bottom plate 31 and the gasket 33, then the fixing columns 32 corresponding to the bottom of the lock body are fixed by adopting a riveting process, so that the restraint belt M is clamped by the bottom plate 31 and the gasket 33, then the mounting feet 144 on the side edge of the lock body correspond to other fixing columns 32 and are fixed by adopting the riveting process again, so that the bottom plate 31, the gasket 33 and the lock body are fixed, at the moment, at least three stress points are formed on the restraint belt M, compared with the traditional fixing mode, the position of the utility model positioned at the bottom of the lock body also forms stress points on the restraint belt M, so that the whole restraint belt M is uniformly stressed, and through forming the avoiding position 145 on the lock body, the fixed point can enter the avoiding position 145 without jacking up the lock body, which provides convenience.

When the lock is used, the lock body and the bolt 2 are respectively fixed at two ends of the restraint band M, and the use mode is that the bolt 2 is inserted into the lock body, and the restraint band M forms a closed loop to achieve the restraint effect on a patient;

further describing the action process, the elastic component 12 is kept in a clamping state with the gear component 13 in a normal state in the housing 11, when the bolt 2 is inserted from the locking part, the positioning hole 21 on the bolt 2 is alternatively clamped with the ratchets 133 at different positions on the gear component 13, so that the gear component 13 rotates, because the elastic component 12 has a reset function, the elastic component 12 is continuously jacked open through the ratchets 133 to realize a continuous clamping-jacking-clamping state, when the bolt 2 reaches a proper position, the gear component 13 and the elastic component 12 are in a clamping state, at the moment, the gear component 13 is also inserted into the positioning hole 21 of the bolt 2, when the bolt 2 is pulled out in the opposite direction, the ratchets 133 cannot jack the elastic component 12, so that the bolt cannot be pulled out to realize locking, when unlocking is needed, the elastic component 12 needs to be attracted by using a magnet, the elastic component 12 and the gear component 13 are separated forcibly, the clamping effect is eliminated, and the gear component 13 can rotate freely at the moment, so that the bolt 2 can be pulled out;

in this embodiment, the locking part includes a base 141 connected to the housing 11, an insertion groove 142 is formed in the base 141 along a rotation direction of the gear assembly 13, a through hole 143 is formed above the insertion groove 142, and the gear assembly 13 may enter the insertion groove 142 through the through hole 143.

In this embodiment, the bottom plate 31 and the gasket 33 are both long strips, the number of the mounting feet 144 is two, the mounting feet are symmetrically and fixedly arranged on two sides of the base 141, the fixing columns 32 on the bottom plate 31 are uniformly and linearly distributed, when the restraint strap M is pulled, the force is uniformly dispersed to each point through the simultaneous stress of three fixing points, and the force is prevented from being excessively concentrated and exceeding the bearing range of the restraint strap M.

The present embodiment describes the gear assembly 13, with reference to fig. 3 and 4;

when the bolt 2 is inserted from the locking part, the ratchet 133 on the left side of the gear body 132 jacks up one end of the elastic component 12, the gear body 132 rotates counterclockwise by taking the first rotating shaft 131 as a support, the bolt 2 is inserted without obstruction at this time, the bolt 2 is forcibly extracted from the locking part, the gear body 132 needs to rotate clockwise, the ratchet 133 on the gear body 132, which is clamped with the elastic component 12, 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 bolt 2 again, so that the bolt cannot be forcibly extracted from the locking part; when the 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 obstruction, and the elastic component can rotate clockwise, so that the bolt 2 can be pulled out;

in addition, in the process that the bolt 2 is inserted into the locking part and clamped with the ratchet 133 on the gear body 132, along with the entering of the bolt 2, the former positioning hole 21 is separated from the ratchet 133, and the latter positioning hole 21 is combined with the next ratchet 133 immediately, so that the gear body 132 can be pushed to rotate and lock, therefore, no matter locking or pushing, one ratchet 133 is always placed in the positioning hole 21, and in the state that no magnet is used for unlocking, if a sheet-shaped object is inserted into the locking part to block the positioning hole 21 behind the bolt 2, the ratchet 133 cannot enter the rear positioning hole 21, the bolt 2 cannot be pushed, and is also in a clamping state, so that the bolt cannot be pulled out, and the potential safety hazard in the background technology can be effectively solved by adopting the gear body 132 to rotate and lock.
