Abstract
A rapid connecting plug of a dental handpiece's motor includes a lock sleeve, a slide sleeve which is slidingly sleeved outside the lock sleeve, a fixed sleeve mounted inside the lock sleeve and two connecting electrodes connected on the fixed sleeve in a penetrated way. A spring is arranged between the slide sleeve and the lock sleeve. The lock sleeve has a containing hole, inside which a steel ball is embedded. The inner wall of the slide sleeve has a raised part used for pressing against the steel ball inwards and a concave position used for containing outboard of the steel ball. Compared with the prior art, rapid dismantling and installation of the connecting plug with the dental handpiece's motor can be realized, thus bringing convenience for a dentist to operate. In the meantime, after plugged with the electric motor of the dental handpiece, the connecting plug can be fixedly connected with the electric motor. Thus, connection firmness is enhanced.
Description
Technical field
The utility model relates to a kind of connection plug, is specifically related to the fast-wiring plug of a kind of dental handpiece with electric notor.
Background technology
Dental handpiece is dentist's common tool, and the common built-in electro-motor of general dental handpiece utilizes the high rotating speed of electric notor to drive the milling tools of dental handpiece front end, and cacodontia is handled.Dental handpiece in use, its motor needs external power supply usually, existing connection plug only can realize that the conducting of circuit connects, its function is comparatively single, can not realize Fast Installation and dismounting, and the latter linked less stable of pegging graft.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide the fast-wiring plug of a kind of dental handpiece with electric notor, and it can realize the Fast Installation dismounting.
For achieving the above object, the utility model adopts following technical scheme:
The dental handpiece fast-wiring plug of motor, comprise lock sleeve, the slip cap that is linked in the lock sleeve outside that slides, be installed in the fixed cover of lock sleeve inside, four link electrodes of cross-under on fixed cover are provided with a spring between slip cap and the lock sleeve, have containing hole on the lock sleeve, be equipped with a steel ball in the containing hole, the inwall of slip cap has one and is used for the lug boss of the inside roof pressure of steel ball and the recess that is used to hold the steel ball outside portion.
The outer peripheral edges of fixed cover are provided with a bearing of trend and its axial consistent chute, are fixed with one on the lock sleeve along its alignment pin that radially extends, and the medial end cross-under of this alignment pin is in chute.
The outside of lock sleeve is bolted with a fitting sleeve.
The front end of lock sleeve is equipped with one and is used to limit the preceding jump ring of slip cap to front slide.
The rear end of lock sleeve is equipped with one and is used to limit the back jump ring that fixed cover moves backward.
The beneficial effects of the utility model are:
Than prior art, connection plug of the present utility model can be realized dismantling fast and installing with the dental handpiece electric notor, is convenient to dentist's operation, simultaneously, after pegging graft with the motor of dental handpiece, can achieve a fixed connection with electric notor, increased the fastness that connects.

Wherein: 1, lock sleeve; 11, containing hole; 12, preceding jump ring; 13, back jump ring; 2, slip cap; 21, lug boss; 22, recess; 3, fixed cover; 31, chute; 4, link electrode; 5, spring; 6, steel ball; 7, alignment pin; 8, fitting sleeve.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, the utility model dental handpiece fast-wiring plug of electric notor, comprise lock sleeve 1, the slip cap 2 that is linked in lock sleeve 1 outside that slides, be installed in the fixed cover 3 of lock sleeve 1 inside, four link electrodes 4 of cross-under on fixed cover 3, the outside of lock sleeve 1 is sheathed with a spring 5, this spring 5 is limited between slip cap 2 and the lock sleeve 1, spring 5 provides an elastic stress that slip cap 2 is promoted forward, have three containing holes 11 on the lock sleeve 1, each containing hole 11 is equipped with a steel ball 6 in all, containing hole 11 is through to its outer surface by lock sleeve 1 inside surface of side wall, has one on the inwall of slip cap 2 and is used for the lug boss 21 of steel ball 6 inside roof pressures and the recess 22 that is used to hold steel ball 6 outsides.
The outer peripheral edges of fixed cover 3 are provided with a bearing of trend and its axial consistent chute 31, be fixed with one on the lock sleeve 1 along its alignment pin that radially extends 7, the medial end cross-under of this alignment pin 7 is in chute 31, utilize alignment pin 7 to prevent that fixed cover 3 from rotating with respect to lock sleeve 1, makes accurately plug-in mounting of two link electrodes 4 then.
The outside of lock sleeve 1 is bolted with a fitting sleeve 8.
The front end of lock sleeve 1 is equipped with one and is used to limit the preceding jump ring 12 of slip cap 2 to front slide.The rear end of lock sleeve 1 is equipped with one and is used to limit the back jump ring 13 that fixed cover 3 moves backward.
During the corresponding grafting of fast joint of the present utility model with electric notor, slip cap 2 is moved backward, make the recess 22 on the slip cap 2 corresponding with steel ball 6, the outside of steel ball 6 is prepended in the recess 22, after fast joint and motor are in place, be after link electrode 4 contacts with the binding post of motor is electrical, release is to slip cap 2 externally applied forces, under the effect of spring 5, slip cap 2 resets, lug boss 21 on the slip cap 2 inwardly pushes steel ball 6, makes steel ball 6 push the inserted terminal of motors, realizes the fixing of fast joint and motor.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection range of the utility model claim all according to technical scheme described above and design.
