Embodiment
According to the adjustable ball-type Universal joint structure that the utility model discloses, please refer to Fig. 1 and Fig. 2, it illustrates stereogram and the sectional drawing of the adjustable ball-type Universal joint structure that embodiment of the present utility model provides respectively; Meanwhile, please refer to Fig. 3, then illustrate the plane exploded view of the adjustable ball-type Universal joint structure that embodiment of the present utility model provides.
In the present embodiment, adjustable ball-type Universal joint structure is mainly made up of with elastic element 30 etc. body 10, ball joint 20.Below again each element is described in detail.
The body 10 of the present embodiment is made up of base 11 and sleeve 12 two-part, base 11 and sleeve 12 are all hollow casing, two-part rely on plural fixed element (as screw) to be assembled to fix (for knowing expression feature of the present utility model, fixed element is not illustrated) in figure, hollow portion branch after assembling defines a fitting recess 17 jointly, all the other elements (as ball joint 20 and elastic element 30) can be supplied to arrange in the inner, and fitting recess 17 top is outwards open opening 15, and the below of adjacent openings 15 has the extension of past fitting recess 17 inside and presents the pressure section 16 slightly inside contracted, as shown in Figure 3.Wherein, ball joint 20 to be installed in fitting recess 17 and to be positioned at the top of elastic element 30, its top exposes to outside opening 15, so that provide external force conflict effect, and ball joint 20 inside has tubular junction 21, internal thread 22 is provided with, for use in providing and being provided with other elements externally threaded and being threaded inside tubular junction 21.In addition, the elastic element 30 of the present embodiment is annulus metal clips, clearly visible by Fig. 4, its central authorities have positioning hole 31, in order to accommodating and provide the location bottom ball joint 20, this elastic element 30 stores an elastic restoring force, its periphery bending downward respectively and with fitting recess 17 bottom form the buffer space that provides compressive strain, and flexibly can be supported in the bottom of ball joint 20, make the top of ball joint 20 and bottom can be subject to seizing on both sides by the arms of pressure section 16 and elastic element 30 respectively fixing, namely the displacement of ball joint 20 Vertical direction in fitting recess 17 is limited, ball joint 20 is made to be in fixed state of rest.
Then, please refer to Fig. 5 A ~ Fig. 5 C, it sequentially illustrates adjustable ball-type Universal joint structure that embodiment of the present utility model provides in the motion conditions schematic diagram of External Force Acting lower ball joint.
When ball joint 20 needs rotation to come adjusting angle and direction, by imposing external force F and acting on ball joint 20, if the large I of the power of external force F overcomes the elastic restoring force of elastic element 30, that is, if when the active force pressed down is greater than elastic restoring force, just ball joint 20 interlock elastic element 30 can be made to move down along fitting recess 17, as shown in Figure 5A, now elastic element 30 can produce compressive strain, ball joint 20 also can depart from original position and produce a height difference H with position during state of rest, a rotatable state is in because its top has departed from the strangulation of the pressure section 16 of fitting recess 17 a little, then, as shown in Figure 5 B, can external force F be relied on again to allow ball joint 20 tilt along substantially horizontal, rotate, namely the angle θ in adjustable ball joint 20 to limit section, finally, when being adjusted to required angle θ, as shown in Figure 5 C, then can rely on and cancel external force F, allow elastic element 30 discharge elastic restoring force make ball joint 20 moves and returns to original position, its angle θ adjusted still can remain unchanged simultaneously, ball joint 20 is made to be accomplished the location of angle and direction.
Adjustable ball-type Universal joint structure disclosed by above-described embodiment, elastic element is metal material, utilizes the change in displacement of elastic element structure to control the direction and power of rotating; But elastic element also can be plastic cement or the elastomer made by rubber elastomeric material.Please refer to Fig. 6, it illustrates the sectional drawing of the adjustable ball-type Universal joint structure that another embodiment of the present utility model provides.
The elastic element 40 of the present embodiment is plastic elastomeric, it utilizes the speciality of plastic cement itself, namely there is wear resistance, toughness and elasticity, then the deformability of its structure after external force F effect can control the direction that ball joint 20 rotates, be with the difference of the elastic element 30 of metal material, the elastic restoring force that the elastic element 40 of plastic cement material provides is to control direction and the angle of ball joint 20 rotation in the mode of interference effect, just interfere many when external force power is strong, power hour is just interfered few, add lubricity and the wear resistance of plastic cement, make it the direction and the angle that control rotation, also have influence on the length in working life simultaneously.
Comprehensively above-mentioned, adjustable ball-type Universal joint structure of the present utility model can be understood, be cannot effectively the problem of keyholed back plate do to improve in function and quality for traditional type ball-type Universal joint structure, and utilize the elastic restoring force of elastic element to regulate for the sense of rotation of ball joint and angle, elastic restoring force due to elastic element can determine and control the power that exerts a force, user can easily and effectively control the rotation of ball joint and be fixed on required direction, so, the utility model is except providing the operation convenience of user, also because force power easily controls, functional and the reliability of its product quality all can obtain effective keyholed back plate, thus can use manpower and material resources sparingly, reduce cost of production, and have more industrial competitiveness.
More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection domain of the present utility model.
