Abstract
Disclosed is a dentistry X-ray machine balance arm which is provided with an end head, an arm and a fixing pin fixed on the side plate; an air spring is mounted between the arm and the end head; a clamp groove plate is mounted in the arm; one end of the air spring is clamped in the groove of the clamp groove plate through a clamp pin; the other end is fixed on the two side plates of the end head through the fixing pin; when the arm is forced to press the air spring, the air spring generates the counterforce to enable the arm to be balance at any position.
Description
Affiliated technical field
This utility model is a kind of equilibrated device in dental X-ray machine mechanical arm optional position that is used for.
Background technology
At present dental X-ray machine counter-jib all is to use the mechanical spring precharge pressure, makes the arm bulb balance at an arbitrary position of slinging, this structure more complicated, process, install, debug cumbersome, and overall weight is heavier, and mechanical spring of long duration is tired easily, causes balance unreliable.If not professional's dismounting because of mechanical spring has very big precharge pressure, is easy to personnel are damaged.
Summary of the invention
For the not enough this utility model that overcomes existing dental X-ray machine counter-jib existence provides a kind of dental X-ray machine counter-jib, can make dental X-ray machine balance more reliable, structure is simpler, and overall weight is lighter, Installation and Debugging are very convenient, even layman's dismounting is not dangerous yet.
The technical scheme that its technical problem that solves this utility model adopts is: dental X-ray machine counter-jib, termination, arm are arranged and be fixed on steady pin on the side plate, between arm and termination, air spring is installed, the draw-in groove plate is installed in arm, one end of air spring is stuck in bayonet lock in the groove of draw-in groove plate, and the other end is fixed on the biside plate of termination with steady pin, thereby makes the air spring pressurized when the stressed effect of arm, air spring produces a counter-force, makes its balance at an arbitrary position.
The beneficial effects of the utility model are, make dental X-ray machine counter-jib balance more reliable, and structure is simpler, the safer convenience of Installation and Debugging.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the profile of Fig. 1 in the A-A direction.
1. terminations among the figure, 2. arm, 3. air spring, 4. draw-in groove plate, 5. bayonet lock, 6. steady pin.
The specific embodiment
One of air spring (3) connects with bayonet lock (5), bayonet lock (5) is stuck in the groove of draw-in groove plate (4), the other end of air spring (3) is bolted on the both sides side plate of termination (1) with steady pin (6), when the stressed effect of arm (2) moves downward down, air spring (3) is given (2) counter-forces of arm by the bayonet lock (5) and the steady pin (6) at two, makes it keep balance.
Claims (2)
1. dental X-ray machine counter-jib has termination, arm and is fixed on steady pin on the side plate, it is characterized in that: between arm and termination air spring is installed.
2. dental X-ray machine counter-jib according to claim 1 is characterized in that: an end of air spring is stuck in the groove of draw-in groove plate with bayonet lock.
