(not shown) on water inlet pipe；Filter screen 53 is installed in 54 groove of nozzle carrier lower cover, is conveyed for filtering out water inlet pipe
Impurities in the fluid come avoid 10 interior conduit of low speed dental handpiece from blocking；Nozzle carrier upper cover 52 by the structure of screw thread with
Nozzle carrier lower cover 54 is screwed on together.The structure is existing docking header structure, is used for perfusion cleaning and is still applicable in, but for wanting
Ask higher when need to complete oiling process, which is then less applicable in.Because with the docking header structure be by
Sealing structure difference between silica gel sheath 51 and low speed dental handpiece 10 causes lubricating oil wastage excessive, to will increase into
This.And opposite, if ensure that the sealing performance between silica gel sheath 51 and low speed dental handpiece 10, operation difficulty can increase
Greatly.
As it can be seen that complicated currently used for equipped low speed dental handpiece docking structure, poor sealing performance cannot achieve oiling function
Can, or even if being used as oiling, oil consumption is also very big, and oiling cost is caused to greatly increase；Simultaneously because lubrication
Oil can be sprayed from gap, and injection direction is unordered, clean trouble to the volume in later period, labor intensity of operating staff increases.
Utility model content
The purpose of this utility model is that overcome the shortcomings of existing technologies, and a kind of low speed dental handpiece is provided to binding
Structure, structure is simple, and good seal performance.
To achieve the above object, the utility model uses following technical scheme:
A kind of low speed dental handpiece docking structure, including the butt joint for being connect with dental handpiece, and for fixed pair
The fixed plate of connector；The center of the fixed plate is equipped with the through-hole being connected to the central tube of the butt joint；The butt joint
Including coupling spindle and set on the connection end cap of coupling spindle one end；The periphery of the coupling spindle be equipped be bordering on middle section seal groove and
It is bordering on the card collar groove of inner end；Sealing ring is equipped in the seal groove；Spring collar is equipped in the card collar groove.
Further, the connection end cap is fixedly connected by flat head screw and the fixed plate；The fixed plate is logical
It crosses soket head cap screw and is fixed on cylinder manifold.
Further, the sealing ring is silica gel material, fluorubber, nitrile rubber, Teflon or rubber material.
Further, the spring collar is flat pattern, and periphery is equipped with circumferential groove；And it is mentioned when being equipped with as by external force
For the axially open of compression space.
Further, the spring collar is rustproof spring steel material or titanium alloy material.
Further, the side of the axially open is the inclined-plane of 30-60 degree.
Further, one end that the spring collar is bordering on sealing ring is equipped with guiding surface.
Further, the seal groove and sealing ring be two, three or more.
Beneficial effect compared with prior art is: the utility model realizes because using spring collar and sealing ring
The sealed attachment of docking structure and low speed dental handpiece, and structure is simple, is easy and fast to dismount；The spring collar used is metal
Material, intensity are high, it is easy to accomplish the positive connection of dental handpiece and docking structure.The guiding surface of use is easily achieved quick peace
Dress.

Specific embodiment
In order to more fully understand the technology contents of the utility model, combined with specific embodiments below to the skill of the utility model
Art scheme is described further and illustrates.
As shown in Figure 1 to Figure 2, a kind of low speed dental handpiece docking structure of the utility model, including be used for and low speed dentistry
The butt joint 31 that mobile phone 10 connects, and the fixed plate 42 for fixing butt joint 31；The center of fixed plate 42 is equipped with and butt joint
The through-hole of 31 central tube connection；Butt joint 31 includes coupling spindle 311 and the connection end cap 312 set on 311 one end of coupling spindle；
The periphery of coupling spindle 311 is equipped with the seal groove for being bordering on middle section and the card collar groove for being bordering on inner end；Sealing ring is equipped in seal groove
32；Spring collar 33 is equipped in card collar groove.
Sealing ring 32 plays the role of clearance seal when docking for butt joint 31 and low speed dental handpiece 10；Spring collar 33
Low speed dental handpiece can be blocked, is avoided by water flow pressure, air-flow without borrowing under external force using the elastic force of itself
It falls off under the action of pressure.When 10 inner diameter hole of low speed dental handpiece is inserted into butt joint 31, spring collar 33 is being pressed
The radial force effect of contracting is lower to shrink；And when butt joint 31 is fully inserted into low speed 10 inner diameter hole of dental handpiece, spring collar 33 blocks
At the step of 10 inner diameter hole of low speed dental handpiece, due to the aperture ratio low speed dental handpiece 10 at 10 step of low speed dental handpiece
Inlet aperture is slightly larger, so spring collar 33 can restore original size under spring force at step, this
When just block low speed dental handpiece 10.
Connection end cap 312 is fixedly connected by flat head screw 20 with fixed plate 42；Fixed plate 42 passes through soket head cap screw 41
It is fixed on cylinder manifold (not shown).
Sealing ring 32 therein is silica gel material, fluorubber, nitrile rubber, Teflon or rubber material, is preferably shaped to O
Type circle.The seal groove and sealing ring used in the present embodiment is two, to realize better seal effect.
Further, spring collar 33 is flat pattern, and periphery is equipped with circumferential groove 330；And it is mentioned when being equipped with as by external force
For the axially open 331 (while can also be easily installed in card collar groove, need to open spring collar at this time) of compression space,
But also spring collar can use the better metal material of intensity.
More specifically, the side of axially open 331 is the inclined-plane of 30-60 degree, production easy to process.For the ease of peace
Dress, one end that spring collar 33 is bordering on sealing ring 32 are equipped with guiding surface 332.Preferably, spring collar 33 is not using
It becomes rusty spring steel material or titanium alloy material, there is good elasticity and intensity, the quick of butt joint and mobile phone may be implemented and can
The connecting relation leaned on.
More specifically, the internal diameter of spring collar 33 is slightly larger than the bottom outer diameter of card collar groove, inside to provide spring collar
The deformation space of diminution.As a preferred embodiment, the width of axially open 331 is substantially equal to internal diameter perimeter and outer diameter week
Long difference.
In conclusion the utility model realizes docking structure and low speed dentistry because using spring collar and sealing ring
The sealed attachment of mobile phone, and structure is simple, is easy and fast to dismount；For the spring collar used for metal material, intensity is high, is easy to real
The positive connection of existing dental handpiece and docking structure.The guiding surface of use is easily achieved Fast Installation.
The technology contents set forth above that the utility model is only further illustrated with embodiment, in order to which reader is easier to manage
Solution, but do not represent the embodiments of the present invention and be only limitted to this, any technology done according to the utility model extends or creates again
It makes, by the protection of the utility model.
