Utility model constitutes
The purpose of this utility model is to overcome weak point of the prior art and a kind of easy for installation, needle stand and installation method thereof that yield rate is improved greatly is provided.
The purpose of this utility model realizes by following approach.
A kind of needle stand, include pedestal, needle guard and needle tubing, needle guard includes rod member and back-end component, and needle tubing is plugged in the rod member, and it is affixed with it, one end of pedestal is an open end, and the other end is the bottom, and pedestal contains the periphery that is contained in rod member, its structural feature is, rod member and back-end component divide body structure, and back-end component is connected an end of rod member and the bottom that back-end component is nested in pedestal, and needle tubing is extended outward by the open end of pedestal.
Movable connection between the rod member of branch body structure and the back-end component, so just rod member can be connected earlier with needle tubing and some glue, the rod member that will have needle tubing again stretches into pedestal by the open end of pedestal, make an end of rod member pass the bottom of pedestal, then with the back-end component retaining ring at rod member one end that stretches out the pedestal bottom, at last the needle guard that connects is embedded into this mode of pedestal bottom with the back-end component button and finishes at last with pedestal and fixedly connected.Because the rod member of needle guard and the branch body structure of back-end component, make rod member can isolate pedestal carry out earlier with needle tubing be connected and the some glue, further connect back-end component and pedestal again, the operation of invocation point glue is become simply, make things convenient for, simultaneously, even the excessive miscellaneous part that also can not have influence on needle stand again of glue during point glue, the yield rate of this needle stand is just improved greatly like this.
On the other hand, because rod member and back-end component are a minute body structure, with before rod member is connected, the dial that is connected the needle tubing on the rod member can be rotated on demand suitable angle, and then back-end component is connected with pedestal at back-end component.When needle tubing being carried out the angle rotation, do not need pedestal is operated, thereby do not need process equipment is handled greatly yet, simple, convenient.
This utility model can further be specially:
Back-end component is a kind of revolving body.Specifically can be:
Being a kind of cylindrical shape, can also be a kind of cone shape.
Revolving body is meant at two points of the two ends of revolving body hypothesis, and 2 company's being aligneds pass revolving body, revolving body is a center of rotation with this line, its each partial rotation all is the same shape when fixing a position when rotated, its feature is that the both sides of centrage are symmetry, so revolving body substantially all is symmetric.And have identical revolution shape opening on the bottom of the corresponding pedestal of back-end component, be convenient to back-end component is connected with the pedestal bottom, can adopt viscose glue to be connected and sealed, also can adopt the button embedding to connect.Can be with the whole embedding pedestal of back-end component bottom, the bottom of pedestal will surround the periphery of whole back-end component like this, the part that also can be back-end component is installed in the opening of pedestal bottom, be inverse-T-shaped such as back-end component, the bottom is by touching the outer surface in the pedestal bottom, and vertically the part button embeds in the atrium of bottom.
Back-end component further can be specially:
Upper bottom portion has an annular boss, its area is greater than back-end component upper bottom surface area, and corresponding inboard, pedestal bottom has step in, when back-end component inserts the pedestal bottom, because the external diameter of annular boss is greater than the internal diameter of interior step, the annular boss embedding leans against on the interior step of bottom.
After can preventing that like this back-end component is fit into the pedestal bottom, produce backward the danger that (promptly along pedestal to the bottom direction) slides.
Lower bottom part is a kind of plane, the area of plane is greater than back-end component bottom surface area, and the outer evagination is in the edge of lower bottom part, and the outside of corresponding pedestal bottom has an outer step, when back-end component inserted the pedestal bottom, this plane tightly was attached to outside this bottom on the step.
After can preventing that like this back-end component is fit into the pedestal bottom, produce the danger of (being the needle tubing direction) slip forward.
When the upper and lower bottom of back-end component all has greater than the long-pending convex surface of back-end component respective bottom surfaces, be that upper bottom portion has annular boss, lower bottom part has the plane of evagination, make back-end component be " worker " font like this along the section of axis direction, the convex configuration at the upper and lower end can be buckled on the pedestal bottom, prevents that back-end component from producing moving forward or backward on the pedestal bottom.
As preferably, preferably a kind of cone shape of back-end component, the upper bottom portion area is less than the lower bottom part area, and upper bottom portion has circular boss, and lower bottom part is a kind of circular compacting plane.
Because shaft section diminishes to upper bottom portion gradually along lower bottom part, like this can be so that back-end component be pushed in the inner chamber of pedestal bottom, the structure at the upper and lower end can prevent snapping go into the back-end component of pedestal bottom produce in the bottom axially movable.
Back-end component can also be a kind of non-revolved body.Specifically:
When back-end component was a kind of cylinder or a kind of cone, its cross section can be a kind of circle, can also be a kind of circle of flat-cut.
Non-revolved body is relative revolving body, after non-revolved body is subjected to peripheral the coating, can't rotate.The cross section of back-end component is as a kind of circle of flat-cut, for a kind of circle lacks the shape plane, that is to say the cylinder of back-end component or cone vertically by flat-cut a part, form a tangent plane, tangent plane is without the cylinder axle center, but vertical with the axle center or angled, the area of barbed portion is less than remaining flat-cut circle.This just makes that having one on the back-end component lacks face, and is same, also has same scarce face on the bottom of pedestal, after the back-end component correspondence is connected to the pedestal bottom, just is fixed on the same position like this, can't rotate again.
Back-end component can also be to be a kind of polygon cylinder.As triangle cylinder, square cylinder etc., the non-revolved body of this class also can guarantee after buckling into the bottom of pedestal, can not rotate.
Back-end component can also further be specially:
The back-end component lower bottom part is a kind of notched compacting plane, and this breach is positioned at the planar end edgewise of compacting.
Like this, with back-end component with when rod member is connected, the dial of needle tubing can be aimed at this breach, at back-end component with when pedestal is connected, rotate this breach, breach is rotated to the angle that becomes to need with the hand steered wing of pedestal, again back-end component and pedestal are fastenedly connected.Further realized producing on demand the requirement of the needle stand of dial and hand steered wing different angles, this simple in structure, convenient.
Above-mentioned breach can be a kind of " V " v notch v, can also be a kind of " W " v notch v, can also be a kind of straight line breach, is positioned on the plane of flat-cut.
The form of breach can be provided with according to the characteristics of producing, but as preferred, the straight line breach on preferably a kind of circle, because in corresponding angle, when the breach and the hand steered wing carry out the angle processing, be a plane as the hand steered wing, straight line and interplanar angle are easier to be determined.
Back-end component can further be specially with being connected of rod member:
Back-end component is connected with rod member by a kind of connector.This connector can be a kind of viscose glue, can also be a kind of fastener, fastens back-end component and rod member respectively, to realize being fastenedly connected of the two.
Can also be:
Back-end component has an inner groovy, and the opening part of this inner groovy is the upper bottom portion of back-end component.
Like this, an end of rod member can insert in this inner groovy, thereby is connected with back-end component.
The inner groovy of back-end component is bar shape, has the ring-shaped groove that a circle concaves on the cylinder, and an end of the rod member that is connected with this back-end component has the annular boss of a circle evagination, but in the ring-shaped groove of this annular boss inlay card in the back-end component inner groovy.
Can realize that like this back-end component is connected with no medium between the rod member, promptly not need other connector to realize connection between the two.This structure is very easy, and it also is convenient, simple being operatively connected.
This inner groovy can also further be specially:
The back-end component inner groovy is a kind of cylinder, has a straight line breach on its cross section, also has a straight line breach on the cross section of rod member one end that is connected with this inner groovy.
Like this, on the end of back-end component inner groovy and rod member tangent plane is arranged all, during installation, the breach tangent plane of the two needs corresponding the installation, and back-end component or rod member after can preventing from like this to install relatively rotate.
The breach of the cylinder of back-end component or cone, lower bottom part and inner groovy is unidirectional mounting plane, or the breach of the cylinder of back-end component, lower bottom part is unidirectional mounting plane, but is axial symmetrical distribution with the breach face of inner groovy.
So-called unidirectional mounting plane, the breach plane of the two is a parallel plane in other words.Being convenient to carry out in the installation process correspondence like this distributes.
One end of rod member has a cavity, and a plurality of muscle bodies are arranged in the cavity, is the circumference rule and distributes, and an end of muscle body points to the center of circle, and needle tubing is installed in this cavity.
This cavity is used to install needle tubing, and a plurality of muscle bodies entad extend, and forms a centre point, and the needle tubing of insertion is positioned at this centre point, can tightly be fixed in the inner chamber of this rod member under the elasticity compacting of muscle body.
This utility model can also be specially:
Also have the protective sleeve of being made up of a plurality of sleeves not of uniform size and belled in the inner chamber of pedestal, rod member is arranged in the minimum telescopic axis intracavity of protective sleeve, after these a plurality of sleeves spread apart, will coat whole needle tubing.
The protective sleeve that these a plurality of sleeves are formed is compressive state when mounted, and after needle set used, this protective sleeve spread apart successively with descending or ascending; like this; protective sleeve has just extended the length of needle stand, is enough to coat whole needle tubing, reaches protective effect.
In such structure; because the installing space of rod member is very little; if give me a little glue by original technology; can make that then gluing process is more difficult; yield rate is lower; the advantage of this utility model in such structure also has been described thus; that is: after rod member and back-end component divide body structure; rod member can be isolated the belled needle stand of this complexity; be connected with needle tubing and some glue in advance; and then the inner chamber that passes the minimum cover of protective sleeve connects back-end component with tail end, makes gluing process more simple, and yield rate also improves greatly.
In sum, this utility model has following advantage compared to existing technology: the rod member and the back-end component of needle guard divide body structure, like this rod member can isolate pedestal carry out earlier with needle tubing be connected and the some glue, further connect back-end component and pedestal again, the operation of invocation point glue is become simply, make things convenient for, simultaneously, even point excessive miscellaneous part that also can not have influence on needle stand again of glue during glue, the yield rate of this needle stand is just improved greatly like this.On the other hand, because rod member and back-end component are a minute body structure, at back-end component with before rod member is connected, to the needle tubing dial and and the hand steered wing of pedestal between angle adjust, just can increase the demand of producing according to the needle stand that requires the production different angles of producing needle set.
