Abstract
The invention relates to a rotating and clamping loop bar of a rocker arm. The rotating and clamping loop bar comprises a mounting base, a through cavity is formed in the mounting baes, a loop bar body is inserted into the cavity, a threaded connector is arranged at the front end of the loop bar body, a mounting head is arranged at the tail end of the loop bar body, and a rotating sliding slot is formed in the surface of the loop bar body; a fixing hole perpendicular to the cavity is formed in the mounting base, a steel ball embedded in the sliding slot is mounted in the fixing hole, and a compression screw compressing the steel ball is arranged in the fixing hole. By rotation of the loop bar body, the mounting head at the tail end of the loop bar body can be driven to rotate, the part connected with the mounting head can rotate relative to the mounting base, and accordingly the purpose of use is achieved. On the other hand, since the surface of the loop bar body is provided with the sliding slot, the steel ball in the fixing hole is inserted into the sliding slot to function in limiting in the sliding slot. Due to limiting and locking functions of the steel ball, the steel ball can be clamped in the sliding groove during returning of the loop bar body, the loop bar body is prevented from returning back and is allowed to have certain bearing capacity.
Description
Technical field
The present invention relates to a kind of mechanical locking, be specifically related to a kind of rocking arm and rotate 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.
Summary of the invention
The object of the present invention is to provide a kind of rocking arm to rotate clamping loop bar, there is certain rotation and bearing capacity, meet the needs used.
For achieving the above object, technological scheme of the present invention 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 present invention is further detailed explanation:
Fig. 1 is the structural representation that rocking arm of the present invention rotates clamping loop bar embodiment.
Embodiment
As shown in Figure 1, rocking arm of the present invention 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 present invention, 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 the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
