Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, the utility model is achieved like this, should be with the medical drag hook packet of closed buckle structure
Crotch 1 and crotch fixed frame 2 are included, is structurally characterized in that, it further includes the crotch lock being rotatably connected on crotch fixed frame 2
Component, the crotch latch components include coordinating to constitute the locking plate 3 of closed buckle structure with 1 opening of crotch；This practicality
It is novel to utilize the crotch latch components being rotatably connected on crotch fixed frame 2, it is closed by the locking plate 3 of crotch latch components curved
1 opening of hook so that crotch 1 constitutes a closed buckle structure under the mating reaction of locking plate 3, avoids being hooked on crotch
Instrument on 1 falls off, and plays good anticreep effect, and the rotation of locking plate 3 do not influence instrument crotch 1 suspension operational,
It is reliable to be particularly suitable for occasions, the medical drag hook stable structure such as infusion.
In the specific implementation, in order to obtain better structural stability, the utility model is also to above-mentioned each critical component
It is designed, wherein as illustrated in figs. 5-7, it includes that locking plate 3 is rotatably connected on crotch to consolidate to the structure of crotch latch components
Determine the pivot pin 4 on frame 2, and the elastic component 5 for making locking plate 3 be engaged always with 1 opening of crotch, the elastic component 5 be around
Torsional spring that is on pivot pin 4 and being contacted with locking plate 3 is made, as shown in figure 5 and figure 7；Under the action of torsional spring elastic force so that lock
3 bottom end of plate keeps certain power that is adjacent to, force direction F as shown in Figure 7, to ensure that envelope with 1 opening of crotch always
The stability of enclosed buckle structure；Since locking plate 3 is rotatably connected on by pivot pin 4 on crotch fixed frame 2, as long as user applies
Add external force, locking plate 3 that can be rotated along pivot pin 4, the opening on crotch 1 is suspended on to open a permission instrument, and
After external force disappearance, instrument is suspended in closed buckle structure.As shown in fig. 6, in assembly, first by locking plate 3, bullet
The hole of property part 5 is inserted into pivot pin 4 above three parts group is integral to the correspondence pilot hole of crotch fixed frame 2.
In the assembly of each critical component, it is also provided with more firm connection structure relationship, as shown in figure 8, described
The upper end of crotch 1 passes through locking plate 3, and by 6 plugged and fixed of positioning pin on crotch fixed frame 2, positioning pin 6 is inserted in crotch
In the centre bore of fixed frame 2, and it is vertical with the part that crotch 1 is plugged in crotch fixed frame 2, it ensure that crotch 1 is solid with crotch
Determine the stability of 2 connection structure of frame, meanwhile, positioning pin 6 is also hidden in crotch fixed frame 2 very well, structure is also more coordinated can
It leans on.When assembly, in crotch fixed frame 2 to the plug division with insertion crotch 1 in pilot hole, the positioning on 1 plug division of crotch is waited for
When hole is overlapped with the centre bore of crotch fixed frame 2, positioning pin 6 is inserted into be fixedly connected with crotch fixed frame 2 and crotch 1, such as Fig. 5 institutes
Show.
For the ease of hanging drag hook, which further includes the steel wire rope 8 for hanging crotch fixed frame 2, steel wire rope 8
It is fixedly connected on crotch fixed frame 2 by set screw 7, as shown in Figure 4；It is put into steel wire in the centre bore of crotch fixed frame 2
After rope 8, is tightened from side by set screw 7, steel wire rope 8 is securely fixed on crotch fixed frame 2.
From attached drawing as can be seen that crotch 1,3 structure of locking plate in the utility model are relatively simple, wherein crotch 1
Need to be i.e. plastic by a straight-bar press-bending, and locking plate 3 only need to be i.e. plastic by molding sheet press-bending, production and processing is simple,
Assembly difficulty is relatively low, and the product after assembling does not have apparent structure dead angle, is not easy long-pending dirty, and cleaning is also more prone to；In order to
Preferably meet actual use needs, the locking plate 3 is additionally provided with the arc screens slot 301 coordinated with 1 bill of crotch, such energy
Enough improve the reliability of locking plate 3 and 1 connection structure of crotch so that locking plate 3 is engaged with 1 bill of crotch more to be stablized.
