Abstract
The utility model relates to a support arm cam-type retraction mechanism which is composed of a cam, a support arm, a support arm torsion spring and a support arm base, and is characterized in that the support arm is supported by the end surface of the cam, and the support arm is arranged in the support arm base, and the support arm torsion spring is arranged between the support arm and the support arm base. The support arm cam-type retraction mechanism has the technical advantages that the structure is simple, the retraction mechanism is accurate and reliable, and the retraction operation is smooth and flexible, and the support arm cam-type retraction mechanism is applicable to more occasions.
Description
Technical field
The utility model relates to a kind of oil recovery machiner, particularly a kind ofly is used for the support arm cam-type jack that oil machinery is looked for water blockoff, water injection well water distribution.
Background technology
Look in the correlative technology field of water blockoff, water injection well water distribution at oil machinery at present, normally used support arm adopts the steel wire rope type jack.Owing to the restriction of short characteristic of steel wire rope type support arm life-span, be an impediment to the quality of the normal folding and unfolding of support arm mechanism.
Summary of the invention
The purpose of this utility model provides a kind of support arm cam-type jack, has solved at present in the oil recovery field problem of normally used support arm complex structure, folding and unfolding difficulty.The utility model designs a kind of support arm cam-type jack, comprise cam, support arm, support arm torsion spring, supporting arm base, it is characterized in that: cam face is propped support arm, and support arm is put in supporting arm base, and the support arm torsion spring is arranged between support arm and the supporting arm base.The utility model has the advantages that simple in structurely, accurately and reliably, folding and unfolding is applicable to more occasions evenly freely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model:
Fig. 1 is that support arm is in retracted state.
Fig. 2 is that support arm is in the relieving state.
The specific embodiment
Comprise cam 1, support arm 2, support arm torsion spring 3, supporting arm base 4 among the figure, it is characterized in that: cam 1 end face is propped support arm 2, and support arm 2 is put in supporting arm base 4, between support arm 2 and the supporting arm base 4 support arm torsion spring 3 is arranged.Cam 1 is subjected to radially revolving force, cam 1 produces and rotatablely moves, thereby makes cam 1 maximum (minimum) radius fulcrum change, and the support arm torsion spring 3 force-closed support arms 2 that make keep contacting with cam 1 always, the then variation of cam 1 fulcrum, support arm 2 is finished the action of folding and unfolding.
Claims (1)
1, a kind of support arm cam-type jack is made up of cam, support arm, support arm torsion spring, supporting arm base, and it is characterized in that: cam face is propped support arm, and support arm is put in the supporting arm base abdomen, and the support arm torsion spring is arranged between support arm and the supporting arm base.
