Abstract
The utility model provides a snap ring type hinge shaft locking device, which comprises a hinge shaft. A ring groove is formed at one end of the hinge shaft; a pair of semicircular snap rings are mounted in the ring groove, and covered with an annular clamping sleeve; and the annular clamping sleeve is fixed through an open clamping spring mounted in the clamping groove at the end head of the hinge shaft. The utility model converts the prior hinge shaft thread locking structure into the snap ring type hinge shaft locking structure, and adopts the open clamping spring to serve the fixation and locking functions, so that the hinge shafts for connecting the bracket of a hydraulic scissor lift are enabled to be in axial clearance fixation, wobble can not be caused to the lift in the transferring work, and the safety is improved. Meanwhile, the snap ring type hinge shaft locking structure not only enables the assembly and disassembly of the hinge shafts to be convenient, but also enables the bracket of the scissor lift to run stably in the ascending and descending processes, and the transferring work to be safe and reliable.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of jacking equipment twisted axis structure, is specifically related to a kind of clasp type twisted axis locking device.
Background technique
The twisted axis of hydraulic fork type elevator of the prior art installs and fixes common employing nut check mode, since hydraulic fork type elevator in use repeatedly the motion of lifting cause twisted axis to rotate, tend to make the locking nut that installs and fixes twisted axis to rotate, the locking nut that the rotation of locking nut causes is loosening to make the lift support produce axial clearance each other, cause the waving and rocking of lift in the carrying working procedure again, safe handling causes great influence to fork type elevator, because the twisted axis diameter of thread is bigger, all brought inconvenience for installation and removal in addition.
Summary of the invention
The purpose of this utility model provides a kind of clasp type twisted axis locking device, it adopts a pair of semicircle snap ring and cutting ferrule location at an end of twisted axis, the mode of jump ring locking is twisted axis fixedly, has solved hydraulic fork type elevator in the prior art because the unsafe factor that twisted axis loosening gap increase causes and the problem of dismounting inconvenience.
The technological scheme that the utility model adopted is that a kind of clasp type twisted axis locking device comprises twisted axis, end at twisted axis is provided with an annular groove, a pair of semicircle snap ring is housed in the annular groove, and snap ring is covered by the ring-type cutting ferrule, and the ring-type cutting ferrule is fixed by the opening jump ring that twisted axis termination draw-in groove is equipped with.
Clasp type twisted axis locking device of the present utility model, change existing twisted axis screw-threaded coupling structure into the clasp type locking mechanism, axial clearance is fixed between the twisted axis of connection hydraulic fork type elevator support, therefore can not cause waving and rocking of lift in the carrying working procedure, improve Security, simultaneously, this clasp type twisted axis locking mechanism, twisted axis easy accessibility not only, and operate steadily when the lifting of fork type elevator support is risen and fallen, the carrying working procedure is safe and reliable.
Description of drawings
Fig. 1 is a clasp type twisted axis locking device structure schematic representation of the present utility model;
Fig. 2 is a clasp type twisted axis locking device structure exploded view of the present utility model.
Among the figure, 1. twisted axis, 2. annular groove, 3. snap ring, 4. ring-type cutting ferrule, 5. draw-in groove, 6. opening jump ring.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of clasp type twisted axis locking device as depicted in figs. 1 and 2, comprises twisted axis 1, end at twisted axis 1 is provided with an annular groove 2, a pair of semicircle snap ring 3 is housed in the annular groove 2, and snap ring 3 is covered by ring-type cutting ferrule 4, and ring-type cutting ferrule 4 is fixing by the opening jump ring 6 that termination draw-in groove 5 is equipped with.
When hydraulic fork type elevator support use the utility model is installed, the clasp type twisted axis is passed the twisted axis fixed hole of two supports, the annular groove 2 of then a pair of semicircle snap ring 3 being packed into, again ring-type cutting ferrule 4 is packed into from the twisted axis end and entangle a pair of semicircle snap ring 3 annular groove 2, at last opening jump ring 6 is strutted and be contained in the termination draw-in groove 5, just finished the installation of clasp type twisted axis locking device.
Because clasp type twisted axis locking device axial dimension is constant, the axial clearance of twisted axis connection hydraulic fork type elevator support also immobilizes relatively, the lift support that is connected by clasp type twisted axis locking can not produce displacement, thereby just can not cause waving and rocking of lift in the carrying working procedure.
Owing to clasp type twisted axis locking device structure, dismounting is all very convenient in addition.
Above-mentioned mode of execution is an example of the present utility model; not enforcement and the interest field that is used for limiting model utility; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
