Abstract
The utility model discloses a sliding type potentiometer, which comprises a push handle, a shell, a spring and a ball and is characterized in that a cylindrical spring hole is arranged on a side wall below the push handle, a spring hole barrier with a center hole is arranged on the opening of the spring hole, the push handle and the spring hole barrier are of a structure of an integrated member, and the radius of the center hole is smaller than the radius of the ball. According to the sliding type potentiometer, the push handle, the spring and the ball are assembled into a whole, so that the ball cannot be popped out of the push handle wholly; and the ball is prevented from being pressed from time to time in a potentiometer assembly process, so that the installation of assembly personnel is greatly facilitated, the assembly efficiency of the potentiometer is increased and the assembly cost of the potentiometer is reduced.
Description
Technical field
The utility model belongs to the carbon-film potentiometer field, more specifically relates to a kind of slidingtype potentiometer, is the low slidingtype potentiometer of a kind of assembly cost.
Background technology
The slidingtype potentiometer plays the important function of control volume in equipment such as sound equipment, sound console, wherein the positioner of potentiometer plays the role of positioning.Positioner adopts spring to add the location technology of steel ball more in the existing technology, because potentiometer spring and the too small hand assembled that needs of steel ball, to make the steel ball extrusion spring in the assembling process and by in the hole that advances to push away on the handle and in the potentiometer shell of packing into, because the less feasible operation of part is inconvenience extremely, always there is steel ball in installation process, to eject, cause installation effectiveness extremely low, increased the processing cost of potentiometer greatly.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of slidingtype potentiometer, a kind ofly can solve the slidingtype potentiometer that bomb with steel balls in the potentiometer installing engineering goes wrong and can simplify the potentiometer assembling procedure.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of slidingtype potentiometer, comprise and push away handle, shell, spring and ball, it is characterized in that, the described handle lower sidewalls that pushes away is provided with columniform spring hole, spring hole opening part is provided with the bullet hole catch of center drilling, and pushing away handle and playing the hole catch is integral member, and the center drilling radius is less than the ball radius.
More excellent, described bullet hole catch is a rubber-like rigid plastics spare.
More excellent, the cross section radius in described spring hole is greater than the ball radius.
More excellent, described spring and ball are located in the spring hole, and ball is located at the outside.
After adopting technique scheme, its beneficial effect is: this potentiometer will push away handle, spring, ball and be assembled into one, ball can wholely not eject and push away outside the handle, push ball in the potentiometer assembling process when not required the time, greatly facilitate the installation of assembler, improve the potentiometer packaging efficiency, reduced the assembly cost of potentiometer.

Fig. 4 is the handle partial cutaway structural representation that pushes away of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figures 1 to 4, a kind of slidingtype potentiometer, comprise and push away handle 2, shell 1, spring 4 and ball 3, push away handle 2 lower sidewalls and be provided with columniform spring hole 22, spring hole 22 opening parts are the bullet hole catch that is provided with center drilling 21, pushing away handle 2 and playing the hole catch is integral member, and center drilling 21 radiuses are less than ball 3 radiuses.Playing the hole catch is rubber-like rigid plastics spare; The cross section radius in spring hole 22 is greater than ball 3 radiuses; Spring 4 and ball 3 are located in the spring hole 22, and ball 3 is located at the outside.
Operation principle: when production pushes away handle 2, spring 4 and ball 3 are placed spring hole 22, ball 3 places the outside, ball 3 extrusion springs 4 in spring hole 22, the restoring force that spring 4 is replied the distortion generation acts on ball 3, ball 3 outwards pushes, but because center drilling 21 radiuses are less than ball 3 radiuses, ball 3 by center drilling 21 places to an evagination part, spring 4, ball 3 and push away that handle 2 is common forms parts.Shell 1 is provided with location hole, pushes away handle 2 and embeds in the shells 1, and ball 3 is subjected to from the extruding force of shell 1 inwall with from the restoring force of spring 4, and ball 3 bounces back in spring hole 22 and be squeezed on shell 1 inwall by the restoring force effect always.When arriving the location hole place that is located at shell 1 place, ball 3 produces locating effect.Potentiometer will push away handle 2, spring 4, ball 3 and be assembled into one, ball 3 can whole not eject and push away outside the handle 2, pushes ball 3 when not required the time in the potentiometer assembling process, greatly facilitates the installation of assembler, improve the potentiometer packaging efficiency, reduced the assembly cost of potentiometer.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
Claims (4)
