Abstract
The utility model discloses a structure capable of preventing torsion springs and twisting arms from disengaging. The structure capable of preventing the torsion springs and the twisting arms from disengaging comprises an upper body (1). Hanging cylinders (2) are arranged in the upper body (1). A cam (3) is arranged at the bottoms of the hanging cylinders. The two sides of the cam are connected with the upper body through screws (4). The screws on one side of the cam are provided with the torsion springs (5). The twisting arm (6) at one end of each torsion spring is connected with the cam and the twisting arm at the other end of each torsion spring is connected with the upper body. The hanging cylinders at the joints of the twisting arms and the upper body are provided with a boss (7). As one boss is additionally arranged on the hanging cylinders on the joint of the twisting arms and the upper body, the bosses are used for abutting against the lower portions of the twisting arms of the torsion springs. The twisting arms are prevented from disengaging from holes in the upper body and the reliability of working of a stopper is improved.
Description
Technical field
the utility model relates to and a kind ofly prevents that torsionspring from turning round the structure that arm is deviate from, and belongs to downhole instrument technical field of structures.
Background technology
be on the increase along with the eccentric water injection water yield regulates quasi-instrument automatically, the kind of blanking plug is also more and more.In order to realize the function of blanking plug cam, on cam, be provided with torsion spring.Turn round arm for one of torsion spring and hang on cam, another is turned round arm and hangs on upper body.Because upper body thickness is limited, hang over turning round arm and can not stretch out upper body on upper body, if turning round arm stretches out body and will affect the input of instrument, so hang on upper body to turn round arm very short, when torsion spring is in the time twisting, because the torsion spring number of turns is few, turn round arm rotational angle large, limited being easy to of arm lengths of turning round hanging in upper body deviate from the hole of upper body, causes cam to lose proper function, affects the reliability of blanking plug work.
Summary of the invention
the purpose of this utility model is, provides a kind of and prevents that torsionspring from turning round the structure that arm is deviate from.Can effectively prevent that blanking plug torsionspring from turning round the structure that arm is deviate from, to overcome the deficiencies in the prior art.
the technical solution of the utility model:
prevent that torsionspring from turning round the structure that arm is deviate from, comprise upper body, be provided with cup in upper body, cup bottom is provided with cam, and cam both sides are connected with upper body through screw; The screw of cam one side is provided with torsion spring, and the arm of turning round of torsion spring one end is connected with cam, and the arm of turning round of the torsion spring other end is connected with upper body; The cup of turning round arm and upper body junction is provided with boss.
compared with prior art, the utility model has increased a boss on the cup of turning round arm and upper body junction, heads on turning round below arm of torsion spring by boss, prevents from turning round arm and deviates from the hole of upper body, has improved the reliability of blanking plug work.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in figure: 1-upper body, 2-cup, 3-cam, 4-screw, 5-torsion spring, 6-turn round arm, 7-boss.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
prevent that torsionspring from turning round the structure that arm is deviate from, as shown in Figure 1.Comprise upper body 1, be provided with cup 2 in upper body 1, cup 2 bottoms are provided with cam 3, and cam 3 both sides are connected with upper body 1 through screw 4; The screw 4 of cam 3 one sides is provided with torsion spring 5, and the arm 6 of turning round of torsion spring 5 one end is connected with cam 3, and the arm 6 of turning round of torsion spring 5 other ends is connected with upper body 1; Turn round arm 6 and be provided with boss 7 with the cup 2 of upper body 1 junction.
described boss 7 is the breach on cup 2, this breach bottom be just against be connected with upper body 1 turn round arm 6 bending parts, make to turn round arm 6 and can in the hole of upper body 1, not deviate from.Through after transformation of the present utility model, owing to turning round arm 6 and cup gap smaller before, so when mounted, torsion spring can be first installed, and then cup is installed, finally again by screw-driving.
