Abstract
The utility model rocking arm rotates clamping loop bar, and comprise fitting seat, described fitting seat is provided with a cavity run through, a loop bar is inserted with in described cavity, the front end of described loop bar is provided with inipple, and the end of described loop bar is provided with mounting head, the surface of described loop bar has the chute of rotation; Described fitting seat offers the fixed hole perpendicular to cavity, the steel ball embedded in chute is installed in described fixed hole, in described fixed hole, be provided with the housing screw compressing steel ball.By rotating loop bar, the mounting head of loop bar end can be driven to rotate, make the parts be connected with mounting head can be mounted opposite seat and rotate, reach the object of use.On the other hand, because the surface at loop bar offers chute, the steel ball in fixed hole inserts in chute, makes steel ball in chute, play spacing effect.Due to the spacing of steel ball and lock function, can be stuck in chute when loop bar rollback, prevent loop bar rollback, make loop bar have certain bearing capacity.
Description
Technical field
The utility model relates to a kind of mechanical locking, is specifically related to a kind of rocking arm and rotates clamping loop bar.
Background technique
Rocking arm is a kind of common mechanical structure, is usually used in machinery or some easy cantilever structures.In special Environmental Conditions, rocking arm is needed to have certain rotation and the ability of carrying.Current telescopic rocking arm can not meet the demand, needs to redesign linkage structure.
Model utility content
The purpose of this utility model is to provide a kind of rocking arm to rotate clamping loop bar, has certain rotation and bearing capacity, meets the needs used.
For achieving the above object, the technical solution of the utility model is: rocking arm rotates clamping loop bar, comprise fitting seat, described fitting seat is provided with a cavity run through, a loop bar is inserted with in described cavity, the front end of described loop bar is provided with inipple, and the end of described loop bar is provided with mounting head, the surface of described loop bar has the chute of rotation; Described fitting seat offers the fixed hole perpendicular to cavity, the steel ball embedded in chute is installed in described fixed hole, in described fixed hole, be provided with the housing screw compressing steel ball.
When adopting technique scheme, by rotating loop bar, the mounting head of loop bar end can be driven to rotate, make the parts be connected with mounting head can be mounted opposite seat and rotate, reach the object of use.On the other hand, because the surface at loop bar offers chute, the steel ball in fixed hole inserts in chute, makes steel ball in chute, play spacing effect.Due to the spacing of steel ball and lock function, can be stuck in chute when loop bar rollback, prevent loop bar rollback, serve the effect of support, make loop bar have certain bearing capacity.
Further, the inwall of described cavity is provided with oil groove, and described fitting seat is provided with the pouring orifice be communicated with oil groove; Seal ring is provided with between described fitting seat and loop bar.This setting can set up lubrication between cavity and loop bar, reduces wearing and tearing between the two.
Further, the surface of described loop bar has two parallel chutes, described chute comprises an arcuate segment and a straightway.Straightway can facilitate steel ball to carry out card to put, and is convenient to fix loop bar.
Further, stage clip is provided with between described steel ball and housing screw.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model rocking arm rotates clamping loop bar embodiment.
Embodiment
As shown in Figure 1, the utility model rocking arm rotates clamping loop bar, comprises fitting seat 1, fitting seat 1 is provided with a cavity run through, and is inserted with a loop bar 2 in cavity, and the front end of loop bar 2 is provided with inipple 3, the end of loop bar 2 is provided with mounting head 4, the surface of loop bar 2 has the chute 5 of rotation.Fitting seat 1 offers the fixed hole perpendicular to cavity, the steel ball 6 embedded in chute 5 is installed in fixed hole, in fixed hole, be provided with the housing screw 7 compressing steel ball 6.The inwall of cavity is provided with oil groove, and fitting seat 1 is provided with the pouring orifice 8 be communicated with oil groove; Seal ring 9 is provided with between fitting seat 1 and loop bar 2.This setting can set up lubrication between cavity and loop bar 2, reduces wearing and tearing between the two.The surface of loop bar 2 has two parallel chutes 5, chute 5 comprises an arcuate segment and a straightway.Straightway can facilitate steel ball 6 to carry out card to put, and is convenient to fix loop bar 2.Stage clip is provided with between steel ball 6 and housing screw 7.
In the utility model, by rotating loop bar 2, the mounting head 4 of loop bar 2 end can be driven to rotate, make the parts be connected with mounting head 4 can be mounted opposite seat 1 and rotate, reach the object of use.On the other hand, owing to offering chute 5 on the surface of loop bar 2, the steel ball 6 in fixed hole inserts in chute 5, makes steel ball 6 play spacing effect in chute 5.Due to the spacing of steel ball 6 and lock function, can be stuck in chute 5 when loop bar 2 rollback, prevent loop bar 2 rollback, serve the effect of support, make loop bar 2 have certain bearing capacity.
Above is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
