Abstract
The utility model discloses a connecting device of a light guiding rod and a cellphone head of a photocuring instrument. The connecting device comprises the cellphone head, wherein the light guiding rod is penetrated on the cellphone head; a first groove is arranged along the periphery of the outer surface of the light guiding rod; the inner surface of the cellphone head is provided with a second groove corresponding to the first groove; and an annular ring is arranged between the first groove and the second groove. The connecting device has simple structure, low manufacturing cost, reliable connection of the cellphone head and the light guiding rod and convenient disassembling; in addition, when the annular ring is clamped into the first groove, people can hear the ringing sound, therefore, people can clearly know that whether the cellphone head and the light guiding rod are installed well or not by discriminating the sound.
Description
Technical field
This utility model relates to a kind of Photocureable instrument, relates in particular to the connecting device of a kind of Photocureable instrument optical rod and hand machine head.
Background technology
People need go to hospital that tooth is treated reparation because of various tooth diseases.Have easy to use, color and luster is true to nature, the light-cured composite of functional advantage such as good is widely used in the clinical material to use as dental filling of dentistry in recent years, be to solidify rapidly under the rayed of 400～500 nanometers because of this light-cured composite in spectral region, so need specialized apparatus that it is solidified, this utility model is used for solidifying the Photocureable instrument of " light-cured composite " exactly.
Current Photocureable instrument comprises main frame, one end of described main frame is provided with hand machine head, hand machine head is provided with optical rod by connecting device, the purpose that connecting device is set is, because optical rod will often change sterilization, this just requires optical rod and the hand machine head can be for convenience detach, then keeps reliable connection when normally using.The present optical rod and the connecting device of hand machine head comprise optical rod, and the end of described optical rod is a tapered end, hand machine head is set on the tapered end of optical rod in the mode of interference fit, such structure, too much inner if optical rod stretches into hand machine head, can cause hand machine head to cooperate tension with optical rod, dismantle very inconvenient, inside is very few if optical rod stretches into hand machine head, then can cause hand machine head to cooperate pine with optical rod, breaks away from easily.On the other hand, optical rod is a fragile article, and it is too much that optical rod stretches into hand machine head, when also being optical rod by excessive swelling, also causes optical rod by broken easily, causes the waste of material, thereby improves use cost greatly.
The utility model content
This utility model provides the connecting device of a kind of Photocureable instrument optical rod and hand machine head, uses this connecting device, can make hand machine head be connected reliably convenient disassembly with optical rod.
In order to solve the problems of the technologies described above, this utility model is solved by following technical proposals:
The connecting device of a kind of Photocureable instrument optical rod and hand machine head, comprise hand machine head, be equipped with optical rod on the described hand machine head, the outer surface of described optical rod is along being circumferentially with first groove, the hand machine head inner surface is provided with second groove corresponding to first groove, and is provided with annular ring between first groove and second groove.
In the technique scheme, described first groove is provided with more than 2 or 2, and correspondingly, described second groove also is provided with more than 2 or 2.
In the technique scheme, the end of described optical rod is a tapered end, makes things convenient for optical rod to slip into the inner surface of hand machine head like this.
In the technique scheme, described hand machine head is an arc near the end of optical rod, and annular ring slips into optical rod eaily like this.
In the technique scheme, described annular ring is "O shape circle.Annular ring is processed into "O shape circle also to be convenient to annular ring and to slip into optical rod, in addition when annular ring by near second groove of optical rod to away from the second groove slippage of optical rod the time, annular ring is processed into "O shape circle, and its convenient advantage of installing is more obvious.
Beneficial effect: this utility model compared with prior art has following beneficial effect:
1) simple in structure, the low cost of manufacture of this utility model, and hand machine head is connected with optical rod reliably, convenient disassembly.
2) snap in first groove when annular ring, can hear clear and melodious sound, so just can know clearly whether hand machine head and optical rod are in place by distinguishing sound.
Description of drawings
Fig. 1 is the structural representation of this utility model and Photocureable instrument.
Fig. 2 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:
Referring to Fig. 1～2, Photocureable instrument comprises main frame 7, one end of described main frame 7 is provided with hand machine head 3, hand machine head 3 is provided with optical rod 1 by connecting device, the purpose that connecting device is set is, because optical rod 1 will often change sterilization, this just requires optical rod 1 for convenience detach with hand machine head 3 energy, then keeps reliable connection when normally using.
The connecting device of Photocureable instrument optical rod and hand machine head, comprise optical rod 1, the outer surface of described optical rod 1 is along being circumferentially with 2 first grooves 10, hand machine head 3 inner surfacies are provided with 2 second grooves 30 respectively corresponding to these two first groove 10 places, and be provided with annular ring 5 between first groove 10 and second groove 30, certain first groove 10 and second groove 30 also can only be arranged to one, but both compare or are preferable over it is arranged to more than 2 or 2, connect more firm like this.
Preferably, the end 12 of described optical rod 1 is a tapered end, makes things convenient for optical rod 1 to stretch in the inner surface of the inner surface of hand machine head 3 and annular ring 5 like this.
Preferably, described hand machine head 3 is an arc near the end 32 of optical rod 1, annular ring 5 is processed into "O shape circle, when annular ring 5 is installed, annular ring 5 is clamp-oned the inner surface of hand machine head 3 near the end 32 of optical rod 1 from hand machine head 3, because the end 32 of optical rod 1 is an arc, annular ring 5 is clamp-oned optical rod 1 eaily like this, in like manner, annular ring 5 is processed into "O shape circle also to be convenient to annular ring 5 and to clamp-on optical rod 1, in addition when annular ring 5 by near optical rod 1 second groove 30 when clamp-oning away from second groove 30 of optical rod 1, annular ring 5 is processed into "O shape circle, its convenient advantage of installing is more obvious.
Operation principle, at first be that annular ring 5 is packed in second groove 30 of inner surface of hand machine head 3, afterwards optical rod 1 is stretched in the hand machine head 3, when first groove 10 of optical rod 1 close end 32 moves to annular ring 5, after hearing clear and melodious sound, continue mobile optical rod 1 afterwards, after hearing clear and melodious sound for the second time, show hand machine head 3 and optical rod 1 installation, this connected mode connects more firm, and for convenience detach, be understood that, this utility model also has another advantage, can know clearly whether hand machine head 3 and optical rod 1 are in place by distinguishing sound.
