Abstract
The utility model discloses a dental X-ray machine balance arm, which is provided with an end head, a bracket rod and a pull rod, wherein a sleeve is fixedly arranged on the bracket rod; a spring is arranged in the sleeve; the pressure of the spring can be changed by adjusting a nut on a lead screw; and during the swing of the arm, a slide bock is tightly pressed by the nut to slide in the sleeve to change the elasticity of the spring, so that the aim of balance at each position is fulfilled.
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 with air spring or mechanical spring precharge pressure, makes the arm bulb balance at an arbitrary position of slinging.There is following problem in the air spring counter-jib: temperature influence is big, and the pressure of the low air spring of temperature diminishes, otherwise becomes big, adds that again air spring can't regulate the size of pressure, thereby causes the imbalance of arm easily, has influenced the use of product; There is following problem at present in the mechanical spring counter-jib: the structure more complicated, install, debug cumbersome.
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, do not receive influence of temperature change, balance is more reliable; Simple in structure, Installation and Debugging are more convenient.
This utility model solves the technical scheme that its technical problem adopted: dental X-ray machine counter-jib; Termination, cradling piece, pull bar are arranged, on cradling piece, be fixed with sleeve, spring is housed in the sleeve; Nut on the adjusting screw mandrel can change the pressure of spring; In the process that arm is being swung, the nut pressed slider slides in sleeve and is changing the elastic force of spring, thereby reaches the purpose of each position balance.
The beneficial effect of this utility model is, makes dental X-ray machine counter-jib balance more reliable, and structure is simpler, and Installation and Debugging are more convenient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified:
Accompanying drawing is the structure chart of this utility model.
1. terminations among the figure, 2. cradling piece, 3. sleeve, 4. screw mandrel, 5. spring, 6. slide block, 7. nut, 8. pull bar.
The specific embodiment
Cradling piece (2) and pull bar (8) link with termination (1); Cradling piece (2) and sleeve (3) relative fixed; In the sleeve (3) of one end sealing spring (5) is housed, adjusting nut (7) makes its pressed slider (6) and makes spring (5) pressurized through screw mandrel (4), and its counter-force makes the whole arm balance that makes progress; In the process that arm is being swung, nut (7) pressed slider (6) slides in sleeve (3) and is changing the elastic force of spring (5), thereby reaches the purpose of each position balance.
Claims (2)
1. a dental X-ray machine counter-jib has termination, cradling piece, pull bar, it is characterized in that: on cradling piece, be fixed with sleeve.
2. a kind of dental X-ray machine counter-jib according to claim 1 is characterized in that: spring is housed in the sleeve.
