Description

A kind of hook with safety locking structure

Technical field

The utility model belongs to a kind of parts of patient's shifting machine, relates to a kind of hook with safety locking structure.

Background technology

The patient with severe symptoms of bed, the patient after operative treatment get more and more, and the mobile inconvenience of these patients has become to cause closes important problem, all likely cause aggravation or wound dehiscence and cause that sb.'s illness took a turn for the worse as shower and the movement that visits the restroom.The heavy patient that especially must perform an operation self cannot move at all, others must be relied on to help moves on Operation trolley, but heavy patient moves the problem that much should be noted that, non-medical staff also cannot help, when running into the less or Women's Medical Specialist of medical worker, the movement of patient is very difficult, can cause delaying therapeutic time, bring life danger to patient, What is more may cause this serious consequence dead.For above-mentioned situation, there is the shifting machine of a kind of patient on the market at present, shifting machine is that patient is moved patient's by hanging on the suspender belt on suspension bracket, because suspension bracket is fixed on the cantilever of shifting machine by linking up with hook, because patient is heavier, hook is needed both to have certain bearing capacity, hook locking reliability is high again, can not dislocate, existing hook structure is simple, the easy dislocation of locking poor reliability, more serious injury is caused to patient, the hook structure that locking reliability is high is very complicated again, use inconvenience, not quick detachable, cost is high, life-span is short.

Utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of locking reliability high, and bearing capacity is large, and the hook of easy-off band safety locking structure.

For achieving the above object, technical solution of the present utility model is: a kind of hook with safety locking structure, and it comprises hanger bulk, dead bolt, torsion spring, screw bolt and nut; The upper end of hanger bulk has the arc hook groove of end band retaining wall projection, the hanger bulk of arc hook groove walls and its lower end has dead bolt and installs groove; The hanger bulk that dead bolt installs groove bottom has central axis and dead bolt and the perpendicular fixed orifice of the central axis of groove is installed; The tongue of dead bolt and shank are that L-type is arranged, and its exterior angle place has the mounting hole matched with the fixed orifice in hanger bulk, and the outer face of shank has the holding tank of torsion spring L-type crotch; The tongue of dead bolt is embedded in dead bolt and installs in groove; Bolt is through in the fixed orifice in hanger bulk and the mounting hole on dead bolt, and the other end is fixed on hanger bulk outer wall by nut locking; One end is against dead bolt and installs on groove lower end wall, the L-type crotch of the other end is through in the holding tank of dead bolt shank, under the effect of torsion spring, dead bolt holds out against on the inwall of the retaining wall projection of hanger bulk, forms locked cavity at retaining wall projection, dead bolt and arc hook groove inner wall.

The tongue of dead bolt described above and the corner of shank are arc angling, and in obtuse angle, the angle between two outside faces in obtuse angle for the angle between two inside faces; The upper surface of shank is fixed with pressing plane.More easily mate with the arc hook groove of hanger bulk.

Bolt described above is socket bolt, and nut is lid shape outer-hexagonal nut.Be convenient to fitting operation.

During use, first depressed by the shank of dead bolt, its tongue is installed groove rear end to dead bolt and is moved, and torsion spring is compressed simultaneously; When the tongue of dead bolt moves on to dead bolt installation groove rearmost end, the opening part of arc hook groove is opened, can hang on the bearing pin of patient's shifting machine upper cantilever one end, now unclamp hand, dead bolt can under the screen resilience effect of torsion spring return, by locked for the bearing pin of patient's shifting machine upper cantilever one end in locked cavity of the present utility model.The utility model locking reliability is high, and bearing capacity is large, and structure is simple, and cost is low, long service life, safe and reliable, easy disassembly.It both can be used in shifting machine, also can be used on other device of the hook needing reliable locking.
