Description
Technical field
This utility model relates to medical apparatus field, espespecially a kind of scalable and can fast assembling-disassembling stretcher.
Background technology
In life, personnel casualty accidents often has generation, and generally, stretcher is conventional one of instrument of suing and labouring.But general stretcher is all medical special product, price comparison is expensive, and majority fixedly weaves into steel or wood, stores and take up room greatly, be also not easy to carry.
Just because of its storage area very much not Portable belt, can not buy in daily life a special stretcher be placed on family for subsequent use or trip be carried in car, when having an accident, just can not carry out transfer timely and suing and labouring.
Summary of the invention
For solving the problem, this utility model provides that a kind of structure is simple, storage area is few, portable scalable and can fast assembling-disassembling stretcher.
For achieving the above object, this utility model adopts following technical scheme to be: a kind of scalable and can fast assembling-disassembling stretcher, comprise two stretcher cloth on arguing for the sake of arguing of arguing for the sake of arguing and be located at, described arguing for the sake of arguing comprises first body of rod, second body of rod flexible in first body of rod and the locking device being located at first body of rod and the second body of rod junction, described locking device comprises sleeve, tommy bar and lock dog, described tommy bar is arranged along the side face of sleeve, one end of described tommy bar is hinged on sleeve side face, the junction of described tommy bar and described sleeve is provided with described lock dog, described sleeve is fixed on the end of first body of rod that second body of rod stretches out, first body of rod is provided with through hole in the position at lock dog place makes lock dog be inserted into the inside of described first body of rod by this through hole.
Preferably, described arguing for the sake of arguing is provided with stopping means, and described stopping means comprises jump ring and is positioned at the fixture block on jump ring.
Preferably, described lock dog is take pin joint as the cam structure in the center of circle.
The beneficial effects of the utility model are:
1. this utility model structure is simple, and parts are few and disassembly and assembly convenient, and storage space is few.
2. this utility model stretcher can realize arguing for the sake of arguing by locking device the free-extension of length, and this kind of stretcher can be made to go for different the wounded, can better and the health of the wounded match, the use that improve the wounded is comfortable.

Detailed description of the invention
Refer to shown in Fig. 1-4, this utility model is scalable and can fast assembling-disassembling stretcher about one, comprise two and argue for the sake of arguing 6 and be located at the stretcher cloth 7 of arguing for the sake of arguing on 6, described argue for the sake of arguing 6 comprise first body of rod 1, second body of rod 2 flexible in first body of rod 1 and be located at the locking device 4 of first body of rod 1 and the second body of rod 2 junction, first body of rod 1 is preferably the pipe that metal material is made, its external diameter is D1 internal diameter is d1, the external diameter of second body of rod 2 is D2, and the outer diameter D 2 of this second body of rod is less than the internal diameter d1 of this first body of rod 1.The lower end of second body of rod 2 is stretched in first body of rod 1, and this second body of rod 2 can protrude upward and this first body of rod of downward retraction.That is, this second body of rod 2 can carry out a relative linear displacement relative to first body of rod 1, obtains a longer body of rod to extend.Locking device 4, comprise: sleeve 41, tommy bar 42 and lock dog 43, described tommy bar 42 is arranged along the side face of sleeve 41, and one end of this tommy bar 42 is hinged on sleeve 41 side face, described tommy bar 42 is provided with described lock dog 43 with the junction of this sleeve 41, namely this lock dog 43 is positioned on an end of tommy bar 42, it is designed to take pin joint as the cam structure in the center of circle, described sleeve 11 is fixed on the end 11 of first body of rod 1 that second body of rod 2 stretches out, first body of rod 1 is provided with a through hole 111 in the position at lock dog 43 place makes lock dog 43 be inserted into the inside of this first body of rod 1 by this through hole 111, pull described tommy bar 42, described lock dog 43 is made to be compressed second body of rod 2 in first body of rod 1 by described through hole 111, to avoid the radial direction shake of described second body of rod 2 in first body of rod 1 and the rotation of circumference.
In addition, arguing for the sake of arguing 6 also comprises a stopping means 5, and this stopping means 5 is positioned at below locking device 4 to be located.This stopping means 5 comprises the first perforate 51 of being positioned on the second body of rod 2 side and is positioned at the second perforate 52 that the first body of rod 1 side is arranged with the first corresponding position of perforate 51, the jump ring 53 of a band fixture block 54 is provided with in second body of rod 2, relative aperture fixture block 54 external diameter of the second perforate 52 and the first perforate 51 is slightly large, the trend that described jump ring 53 makes described fixture block 54 have ejection to be all the time positioned at outside this first perforate 51 and the second perforate 52.When after the second perforate 52 that fixture block 54 stretches out at first body of rod 1, second body of rod 2 in first body of rod 1 move axially and circumference in first body of rod 1 is rotated and is all controlled.
The both sides of described stretcher cloth 7 are all connected with a fixing band, the coupled limit of described fixing band is isometric, the back side of described fixing band is provided with VELCRO, the back side of described stretcher cloth 7 is provided with the stretcher cloth VELCRO coordinated with described VELCRO, fixing band on each limit of stretcher cloth is wrapped in respectively argues for the sake of arguing on 6, and is fixed by the bonding of VELCRO and stretcher cloth VELCRO.
This utility model can carry out according to different the wounded's physical conditions arguing for the sake of arguing 6 the adjustment of length, the shortening process of stretcher is as described below: first open locking device 4, and fixture block 54, second body of rod 2 being then pressed into stopping means 5 bounces back in first body of rod 1; The elongation process of stretcher is as described below: second body of rod 2 is from pull-out in first body of rod 1, after certain length, the fixture block 54 of jump ring 53 springs into the first perforate 51 of second body of rod 1 and the second perforate 52 of first body of rod 1, then, be wrenched locking device 4, after 6 elongations that make thus to argue for the sake of arguing, axial length is fixed.When not needing to use, tearing VELCRO, making stretcher cloth 7 and arguing for the sake of arguing 6 points to open, open locking device 4, be then pressed into fixture block 54, second body of rod 2 of stopping means 5 from pull-out in first body of rod 1, just dismounting can be realized by easy steps, just assembling stretcher can be completed by the reverse installation of demounting procedure.
Above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from this utility model design spirit; the various distortion that the common engineers and technicians in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
