Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1-5, the utility model relates to a spring force adjusting device of display support, including extension spring, adjusting screw, support seat, bearing, locating pin, gear, hexagonal head pivot. The front end of the upper arm body 4 is connected with the ball head 1 through an upper bracket 2, and the rear end of the upper arm body 4 is provided with a lower bracket 3. The support base 53 is fixed at the bottom of the upper arm body 4, and the upper arm body 4 and the support base 53 are fixed by adopting the socket head cap screws 7. The side surface and the top surface of the bracket seat 53 are respectively provided with a first bearing 54 and a second bearing 55, the hexagonal head rotating shaft 50 is connected with a second gear 57 through a second positioning pin 59 after penetrating through the second bearing 55, one end of the adjusting screw 52 is connected with a first gear 56 through a first positioning pin 58 after penetrating through the first bearing 54, the first gear 56 is meshed with the second gear 57, the other end of the adjusting screw 52 is connected with a first spring connector at the end part of the extension spring 5, the outer circle of the first spring connector is coated with red, and the second spring connector at the other end of the extension spring 5 is sleeved on the fixing pin 42 at the bottom of the upper arm body 4.
The utility model discloses in, in order to facilitate looking over the tensile change of spring, be equipped with spring pulling force display window 41 on the upper arm body 4, the front side of spring pulling force display window 41 is equipped with "-" mark, the rear side "+" mark of spring pulling force display window 41. In order to facilitate adjustment of the hexagonal-head rotation shaft 50, the hexagonal-head rotation shaft 50 is located in the through hole of the upper arm body 4.
The utility model discloses at the during operation, when needs increase spring force, clockwise twist and change hexagonal head pivot 50, two 57 drive gear 56 and rotate, under adjusting screw 52's effect, extension spring 5 is elongated, and the spring force increases. Meanwhile, the red mark of an outer circle of the spring joint is seen to move towards the direction of the "+" mark through the spring tension display window 41.
When the spring force needs to be reduced, the hexagonal head rotating shaft 50 is screwed anticlockwise, the gear II 57 drives the gear I56 to rotate, the extension spring 5 is retracted under the action of the adjusting screw rod 52, and the spring force is reduced. Meanwhile, the red mark of an outer circle of the spring joint is seen to move towards the mark direction through the spring tension display window 41.
The utility model discloses an adjust extension spring 5's length, change the size of spring force to satisfy the difference of the upper arm body 4 and hang important the asking, in order to match the display of not equidimension specification.
