Abstract
The invention relates to a mechanism for automatically clamping a dental handpiece bur. The mechanism comprises a shaft sleeve and a pressing part, the middle of the interior of the shaft sleeve is provided with an inner wall segment with a taper, the lower end of the pressing part is located at the position where the taper is located in the shaft sleeve, the upper end of the pressing part upwards extends to the exterior of the shaft sleeve, and the pressing part can vertically slide along the shaft sleeve; the side wall of the lower end of the pressing part is provided with clamping holes which are oppositely formed, clamping parts are arranged in the clamping holes, the clamping parts are provided with tapers matched with the inner wall of the shaft sleeve, and the upper ends of the clamping parts penetrate through the clamping holes into the pressing part to clamp a bur arranged in the pressing part. Compared with a traditional bur clamping mode through a three-valve spring, the mechanism for automatically clamping the dental handpiece bur has the advantages that one less groove is formed, the machining technology is greatly simplified, the cost is significantly lowered, and the clamping force can reach the clamping force size of the bur clamping mode through the three-valve spring.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of mechanism of automatic clamping dental handpiece car pin.
Background technology
Present dental handpiece uses three lobe springs to clamp car pin, the structure processing difficulties of this clamping, complex process.Use the pressing piece of the mode clamping trolley pin of three lobe springs, add man-hour requirement and first on the workpiece of tubulose, output three grooves, then the folder needle of three couplings processed is installed in three grooves, the pressing piece clamping trolley pin of this clamping is very firm, but processing technique is complicated, and cost is higher.
Summary of the invention
In sum, for overcoming the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of mechanism of automatic clamping dental handpiece car pin.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of mechanism of automatic clamping dental handpiece car pin, comprise axle sleeve, pressing piece, the inwall that one section has tapering is provided with in the bosom position of described axle sleeve, the lower end of described pressing piece is in the position being provided with tapering in described axle sleeve, the upper end of described pressing piece extends up to the outside of described axle sleeve, and described pressing piece can do the slip of upper and lower displacement along described axle sleeve;
The sidewall of described pressing piece lower end has the clamping hole be oppositely arranged, holder is provided with at described clamping hole place, described holder has the tapering matched with described sleeve lining, and the upper end of described holder is through described clamping hole in described pressing piece, and the lower end of described holder is between described axle sleeve and described pressing piece;
Position in the described axle sleeve that described pressing piece bottom is corresponding is provided with spring, and the bottom that this spring props up described pressing piece makes described holder clamp to be in the car pin of described pressing piece inside.
The invention has the beneficial effects as follows: the mode clamping trolley pin using two lobe springs, only need on the pressing piece of tubulose, output two grooves and holding tank.The mode comparing three traditional lobe spring clamping car pins opens a groove less, and processing technique simplifies greatly, and cost declines to a great extent.Be provided with the spring increasing chucking power simultaneously in the below of pressing piece, make chucking power also can reach the chucking power size of three lobe spring clamping car pins.
On the basis of technique scheme, the present invention can also do following improvement:
Further, described spring bottom is enclosed within outside the top of meson, and this meson is fixed in described axle sleeve, and is provided with guide through hole car pin being inserted described pressing piece inside in the middle part of described meson.
Above-mentioned further beneficial effect is: car pin, under the guiding of meson, more easily passes the inside that spring is inserted into pressing piece.
Further, the lower end of described pressing piece is provided with step, and described spring props up described step.
Accompanying drawing explanation
Fig. 1 is explosive view of the present invention;
Fig. 2 is the overall sectional view of the present invention;
Fig. 3 is the sectional view of axle sleeve.
In accompanying drawing, the list of parts representated by each label is as follows:
1, axle sleeve, 2, pressing piece, 3, clamping hole, 4, holder, 5, spring, 6, car pin, 7, meson, 8, guide through hole, 9, step.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As illustrated in fig. 1 and 2, a kind of mechanism of automatic clamping dental handpiece car pin, comprise axle sleeve 1 and pressing piece 2, the lower end of described pressing piece 2 is provided with step 9.The inwall that one section has tapering is provided with in the bosom position of described axle sleeve 1, the lower end of described pressing piece 2 is in the position being provided with tapering in described axle sleeve 1, the upper end of described pressing piece 2 extends up to the outside of described axle sleeve 1, and described pressing piece 2 can do the slip of upper and lower displacement along described axle sleeve 1.
The sidewall of described pressing piece 2 lower end has the clamping hole 3 be oppositely arranged, holder 4 is provided with at described clamping hole 3 place, described holder 4 has the tapering matched with described axle sleeve 1 inwall, and the upper end of described holder 4 is through in described clamping hole 3 to described pressing piece 2, and described spring 5 props up described step 9.Use the mode clamping trolley pin 4 of two lobe springs, only need to output two grooves and clamping hole 3 on the pressing piece 2 of tubulose.The mode comparing three traditional lobe spring clamping car pins opens a groove less, and processing technique simplifies greatly, and cost declines to a great extent.
Position in the described axle sleeve 1 that described pressing piece 2 bottom is corresponding is provided with spring 5, and the bottom that this spring 5 props up described pressing piece 2 makes described holder 4 clamp the car pin 6 being in described pressing piece 2 inside.The present invention uses two lobe spring clamping trolley pins, relative chucking power can decline to some extent, in order to make movement have larger chucking power, in the below of pressing, use the good spring 5 of elasticity to withstand pressing piece 2, make chucking power also can reach the chucking power size of three lobe spring clamping car pins.
Described spring 5 bottom is enclosed within outside the top of meson 7, and this meson 7 is fixed in described axle sleeve 1, and is provided with the guide through hole 8 car pin 6 being inserted described pressing piece 2 inside in the middle part of described meson 7.Car pin 6, under the guiding of meson 7, more easily passes the inside that spring 5 is inserted into pressing piece 2.When taking out the car pin 6 be clamped in axle sleeve 1, press down pressing piece 2 Compress Spring 5 and drive holder 4 to bottom offset, thus strut the holder 4 be oppositely arranged and unclamp car pin 6, finally take out car pin 6 and just can.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
