Abstract
The utility model relates to a self-locking universal joint which comprises an outer bulb (1) and an inner bulb (2), wherein the inner bulb (2) is positioned in the outer bulb (1), a pin roll (4) penetrates through the inner bulb (2), is inserted into the outer bulb (1) and is connected with a spring (3), and the spring (3) is connected with a rope (5). According to the self-locking universal joint, through a simple structure combination of the pin roll, the spring and the rope, the universal joint can be easily unlocked or locked to achieve the effect of simple operation. The pin roll, the spring and the rope are all arranged inside the universal joint, cannot be influenced by outside factors, and thus the work stability is improved, and the integral attractiveness of the outside of the universal joint cannot be affected. The end B of the rope is connected with the end A of the rope of the next stage of universal joint, and thus multiple stages of universal joints can synchronously act, and the working efficiency of the multiple stages of universal joints is increased.
Description
Technical field
The utility model relates to a kind of universal joint, relates in particular to a kind of self-locking universal joint.
Background technique
At present, known universal joint is by axle, outside fastening screw, fixedly parts such as jump ring or straight-tooth engagement are formed.Conventional universal joint is made of the connecting rod of one group of spatial vertical, utilizes the rotatability of connecting rod to adjust space angle.The user must unclamp fastening screw (two-way) earlier in use, or engaging gear, behind the adjustment several angle, needs to screw fastening screw through twice, just can reach the locking purpose.If the more piece connecting rod, need the step of process will be more, numerous and diverse.And when the certain intensity of needs, need tighten fastening screw energetically.Therefore, common universal joint connecting body, complex structure, outside fastening structure is many, build is big, operating procedure is various, too fat to move not attractive in appearance.
Summary of the invention
It is not enough and propose that complex structure, the operating procedure that the utility model has at existing universal joint is various etc., aims to provide simple in structure, easy to operate a kind of self-locking universal joint.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of self-locking universal joint comprises outer bulb and interior bulb, and interior bulb is positioned at outer bulb, and bulb inserted outer bulb in bearing pin passed, and bearing pin is connected with spring, and spring is connected with rope.The pulling rope can spur spring, drives bearing pin and extracts out from the jack of outer bulb, and outer bulb and interior bulb can arbitrarily be rotated.After unclamping rope, utilize the elasticity of spring that bearing pin is inserted in the jack of outer bulb, make the locking of outer bulb and interior bulb.
As preferably, outer bulb is connected with first strut, and interior bulb is connected with second strut.First strut can be controlled the rotation of outer bulb easily, the rotation of bulb in second strut can be controlled easily.
As preferably, first strut and second strut are hollow, and rope passes first strut and second strut.Rope passes from steady arm inside, has guaranteed the stability of rope work thereby make rope can not be subjected to the extraneous factor influence, and has made the outward appearance of universal joint more attractive in appearance.
As preferably, outer bulb inwall is provided with jack, and jack openings is the bulb center outward.Outer bulb inwall is provided with the many places jack, and each jack openings is the center of bulb outward, has guaranteed that interior bulb turns to when arbitrarily angled, and bearing pin all can insert in the jack of outer bulb.
As preferably, spring is positioned at bulb inside.Spring is in inside, can not be subjected to the influence of extraneous factor, thereby has guaranteed the stability of spring work.
According to the technical solution of the utility model, a kind of self-locking universal joint can open and lock universal joint by bearing pin, spring and the simple textural association of rope easily, reaches function simple to operate.Bearing pin, spring and rope all place universal joint inside, have guaranteed that not only bearing pin, spring and rope all can not be subjected to the influence of extraneous factor, thereby reduce the stability of work, but also can not have influence on the aesthetic property of universal joint external overall.Rope B end is connected with the rope A end of next stage universal joint, can realizes multistage universal joint synchronization motion, improved the working efficiency of multistage universal joint.
Description of drawings
Fig. 1 is the structural representation one of a kind of self-locking universal joint of the utility model.
Fig. 2 is the structural representation two of a kind of self-locking universal joint of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
A kind of self-locking universal joint comprises outer bulb 1 and interior bulb 2, and interior bulb 2 is positioned at outer bulb 1, and bulb 2 inserted outer bulb 1 in bearing pin 4 passed, and bearing pin 4 is connected with spring 3, and spring 3 is connected with rope 5.
The A end of pulling rope 5, rope 5 pulling springs 3 also stretch in the space 9 spring 3, and spring 3 drives bearing pins 4 and detaches from jack 7, and outer bulb 1 and interior bulb 2 can arbitrarily be rotated.
Unclamp rope 5, utilize the elasticity of spring 3 that bearing pin 4 is inserted in the jack 7, make outer bulb 1 and 2 lockings of interior bulb.
The B end of rope 5 is connected with the A end of next stage universal joint rope 5, can realizes multistage universal joint synchronization motion.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
