Abstract
The utility model relates to a self-clamping dental straight head section which comprises a front shell (9), a back shell (7) and a rotary clamping mechanism positioned in the shells. The utility model is characterized in that the rotary clamping mechanism comprises a rotary sleeve body (2) installed in the shells through a bearing (6), and a shifting fork shaft (5) and a guide clamping sleeve (1) which are positioned in the rotary sleeve body (2). The shifting fork shaft (5) is sheathed in the rotary sleeve body (2) through a stop block (8) in a movable fit mode. The guide clamping sleeve (1) is combined with the rotary sleeve body (2) in a stationary fit mode. The front end of a locking torsion spring (4) positioned in the clamping sleeve (1) is fixedly connected with the rotary sleeve body (2), and the back end of the locking torsion spring is fixedly connected with the shifting fork shaft (5).
Description
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of dental self-clamp type dentistry straight handpiece specifically.
The dental therapeutic apparatus of prior art mostly is the three-clove style chuck with the clamp mechanism of straight handpiece, and the replacing of treatment tools such as its drilling tool, grinding tool, installation all need the operator to realize by three claws of rotation tapered sleeve driving.Its weak point is that structure is comparatively complicated, production cost is higher, and operation is also more loaded down with trivial details.
The purpose of this utility model provides a kind of simple and reasonable for structure, self-clamp type dentistry straight handpiece easy for operation with regard to being to overcome above-mentioned weak point of the prior art.
Self-clamp type dentistry straight handpiece of the present utility model comprises forward and backward housing, is positioned at the intravital rotation clamp mechanism of shell; Described rotation clamp mechanism comprises by bearing and is installed in the intravital rotation body of shell, is positioned at intravital declutch shift shaft of rotary sleeve and guiding gripping sleeve; Described declutch shift shaft is sleeved in the rotation body with movingly relation by locating part; Described guiding gripping sleeve mode combines with the rotary sleeve bulk phase with the bonded mode of rotary sleeve bulk phase; The front end and the rotary sleeve bulk phase of locking torsion spring that is positioned at the guiding gripping sleeve is affixed, its rear end and declutch shift shaft Joint.
For avoiding treatment tools such as drilling tool, grinding tool changing, skidding off in head when (under the stopped status) is installed, this utility model is pressed with a damped ring at the front end face place of described guiding gripping sleeve by centring sleeve.
The purpose that combines in the stationary fit mode between guiding gripping sleeve in this utility model and the rotation body is to guarantee that for outer it realizes synchronous rotation between the two; For realizing that this purpose can adopt connecting modes such as multiple known technology such as key connecting, pin connection or welding to realize.
Operation principle of the present utility model is as follows:
At first the treatment tool with required use inserts in the head, starting device power set afterwards, this moment, declutch shift shaft began to rotate under the driving of external flexible axle, thereby driving the locking torsion spring that is positioned at the guiding gripping sleeve reverses, can automatically the pad in being plugged in the torsion spring hole be clamped when locking torsion spring endoporus dwindles, making becomes a common rotary body between treatment tool and the rotation clamp mechanism.(the locking torsion spring during shutdown in the head is turned round and is in free state) can be extracted or insert to the replacing of treatment tool easily under stopped status.
Advantage of the present utility model is simple and reasonable for structure, and being installed of tool heads makes things convenient for freely, for manipulating the condition of providing convenience; In addition, due to architectural feature of the present utility model, it is low to make that also this product has a production cost, the advantage of being convenient to suitability for industrialized production and applying on a large scale.
Accompanying drawing is that master of the present utility model cuts open figure.
This utility model is done with detailed description below with reference to embodiment (accompanying drawing): self-clamp type dentistry straight handpiece of the present utility model comprises procapsid (9) and the back casing (7) that combines by the suit mode, and is positioned at the intravital rotation clamp mechanism of shell; Described rotation clamp mechanism comprises by forward and backward two bearings (6) and is installed in the intravital rotation body of shell (2), is positioned at the declutch shift shaft (5) of rotation body (2) and the gripping sleeve (1) that leads; Between forward and backward two bearings (6), be provided with the bearing positioning sleeve (3) of position-limiting action together; Described declutch shift shaft (5) is sleeved in the rotation body (2) with movingly relation by spacing ball (8); Described guiding gripping sleeve (1) combines with rotation body (2) in the mode of stationary fit; The front end that is positioned at the locking torsion spring (4) of guiding gripping sleeve (1) is fixedly mounted between guiding gripping sleeve (1) and the rotation body (2) its rear end and declutch shift shaft (5) Joint; For avoiding treatment tool heads such as drilling tool, grinding tool changing, skidding off in head when (under the stopped status) is installed, this utility model is pressed with a damped ring (10) at the front end face place of described guiding gripping sleeve by centring sleeve (11); Described centring sleeve (11) is except that having the damped ring of press-fiting (10) effect, and it the more important thing is centering, the position-limiting action that treatment tool heads such as drilling tool, grinding tool are installed.
Claims (2)
1, a kind of self-clamp type dentistry straight handpiece, it comprises forward and backward housing (9) (7), be positioned at the intravital rotation clamp mechanism of shell, it is characterized in that: described rotation clamp mechanism comprises by bearing (6) and is installed in the intravital rotation body of shell (2), is positioned at the declutch shift shaft (5) of rotation body (2) and the gripping sleeve (1) that leads; Described declutch shift shaft (5) is sleeved in the rotation body (2) with movingly relation by locating part (8); Described guiding gripping sleeve (1) combines with rotation body (2) in the mode of stationary fit; Be positioned at the front end and rotation body (2) Joint, its rear end and declutch shift shaft (5) Joint of the locking torsion spring (4) of guiding gripping sleeve (1).
2, self-clamp type dentistry straight handpiece according to claim 1 is characterized in that: the front end face place at described guiding gripping sleeve (1) is pressed with a damped ring (10) by centring sleeve (11).
