Abstract
The invention discloses a kind of snake bone steel wire position limiting structure,Including snake bone,Engaging lug,Connecting shaft,Mounting groove is provided with the inner wall of the snake bone,It is connected together in the mounting groove and is provided with banking stop,Threaded hole of steel is provided with the banking stop,The central axes of the threaded hole of steel and snake bone axis parallel,Banking stop is added on the snake bone of the present invention,Banking stop is engaged with the end face in the mounting groove of snake bone,Two mating surfaces by making banking stop are engaged with the inclined-plane of mounting groove,Banking stop is set not fall into snake bone,Again since the arc radius of banking stop is consistent with snake bone radius,Therefore snake bone surface does not have protrusion after installing,Threaded hole of steel on banking stop can fix steel wire,A position-limiting action is played to steel wire,Snake bone inner space is influenced smaller,Using more flexible and changeable,Banking stop is only needed to change to change the steel wire that the diameter of threaded hole of steel on banking stop is suitable for different-diameter.
Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of snake bone steel wire position limiting structure.
Background technology
Steel wire in snake bone must be close to wall, and otherwise when snake cyrtosis, steel wire may cross center, cause to bend
It is bad.In order to solve this problem there are two kinds of solution methods, one kind is to extrude groove on snake bone, allows steel wire to walk inside to limit
Make steel wire, but this mode has the drawbacks of very serious, when snake bone wall thickness is thicker, will be to snake bone inside
Space produce considerable influence.Also another mode, exactly slots on snake bone, and it is T-shaped with holes then to remanufacture some
Component, by the T-shaped perpendicular hole position for being inserted partially into snake bone and reserving, T-shaped horizontal part ensures that T-shaped component will not fall into snake bone
It is interior, a hole is provided with above T-shaped perpendicular part to fix steel wire.This method can more flexibly, by controlling T-shaped ruler
Very little, to save the inner space of snake bone, current is spacing, after being assembled with snake bone, can be higher by snake bone surface, cause boss, this
Practicality is mainly contrasted with second method.
The content of the invention
It is an object of the invention to provide a kind of snake bone steel wire position limiting structure, to solve proposed in the above background technology ask
Topic.
To achieve the above object, the present invention provides following technical solution：A kind of snake bone steel wire position limiting structure, including snake bone,
Engaging lug, connecting shaft, are provided with mounting groove on the tube wall of the snake bone, are connected together in the mounting groove and are provided with banking stop,
Threaded hole of steel, central axes and the snake bone axis parallel of the threaded hole of steel are provided with the banking stop.
Preferably, the tube wall of the snake bone is provided with mounting groove
Preferably, the engaging lug has four, and four engaging lugs are symmetrically distributed in the both ends of snake bone two-by-two.
Preferably, the snake bone is hollow cylindrical structure.
Preferably, the end set of the snake bone has engaging lug, and the two neighboring snake bone passes through connection by connecting shaft
Ear connects.
Preferably, banking stop is engaged with the end face in the mounting groove of snake bone.
Preferably, the arc radius of banking stop is consistent with snake bone radius.
Compared with prior art, the beneficial effects of the invention are as follows：Banking stop, banking stop are added on the snake bone of the present invention
It is engaged with the contact surface in the mounting groove of snake bone, two mating surfaces by making banking stop are engaged with the inclined-plane of mounting groove,
Banking stop is set not fall into snake bone, but the arc radius due to banking stop is consistent with snake bone radius, therefore snake bone surface after installing
Do not have a protrusion, the threaded hole of steel on banking stop can fix steel wire, a position-limiting action be played to steel wire, to snake bone inner space
Influence is smaller, and use is more flexible and changeable, only needs to change banking stop and is suitable for not to change the diameter of threaded hole of steel on banking stop
With the steel wire of diameter.
Brief description of the drawings
The snake bone that Fig. 1 is the present invention connects positive structure diagram；
Fig. 2 is the snake bone side structure schematic view of the present invention；
In figure：1- snakes bone, 2- engaging lugs, 3- mounting grooves, 4- connecting shafts, 5- threaded hole of steel, 6- banking stops.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Please refer to Fig.1 and Fig. 2, the present invention provide a kind of technical solution：A kind of snake bone steel wire position limiting structure, including snake bone 1,
Engaging lug 2, connecting shaft 4, are provided with mounting groove 3 on the tube wall of snake bone 1, are connected together in mounting groove 3 and are provided with banking stop 6, limit
Threaded hole of steel 5, central axes and 1 axis parallel of snake bone of threaded hole of steel 5 are provided with bit slice 6.
In the present embodiment, it is preferred that the tube wall of snake bone 1 is provided with mounting groove 3
In the present embodiment, it is preferred that engaging lug 2 has four, and four engaging lugs 2 are symmetrically distributed in the both ends of snake bone 1 two-by-two.
In the present embodiment, it is preferred that snake bone 1 is hollow cylindrical structure.
In the present embodiment, it is preferred that the end set of snake bone 1 has engaging lug 2, and two neighboring snake bone 1 is worn by connecting shaft 4
Engaging lug 2 is crossed to connect.
The operation principle and process for using of the present invention：After the present invention installs, in the mounting groove 3 of banking stop 6 and snake bone 1
End face be engaged, two mating surfaces by making banking stop 6 are engaged with the inclined-plane of mounting groove 3, banking stop 6 is not fallen into
In snake bone 1, and the arc radius due to banking stop 6 is consistent with 1 radius of snake bone, therefore 1 surface of snake bone does not have protrusion after installing, and limits
Threaded hole of steel 5 on bit slice 6 can fix steel wire, and a position-limiting action is played to steel wire, smaller on the influence of 1 inner space of snake bone,
Using more flexible and changeable, only need to change banking stop 6 and be suitable for different-diameter to change the diameter of threaded hole of steel 5 on banking stop 6
Steel wire.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace
And modification, the scope of the present invention is defined by the appended.
