Abstract
The invention relates to a clamping apparatus capable of rotating and automatically stretching out and drawing back. The clamping apparatus comprises a clamping apparatus shell, a clamping apparatus head and a tapered screw. When the tapered screw rotates, the clamping apparatus head automatically stretches out; when the tapered screw reversely rotates, the clamping apparatus head automatically draws back. With adoption of the function, a weight with a middle hole can be locked and then moved and hoisted.
Description
Technical field
The present invention relates to a kind of clamping fixture, be widely used in production and transport field.
Background technology
Enterprise produces and needs to lift coil of strip or the steel ingot of middle with hole in lifting carrying, wastes time and energy in prior art to the carrying of coil of strip or steel ingot.
Summary of the invention
Because the above-mentioned problems in the prior art, the technical problem to be solved in the present invention is to provide the jig that a kind of structure is simple, cost is low, easy and simple to handle, with carrying coil of strip nimbly and freely, save work-hours to transport and on-site hoisting, increase production efficiency.
For reaching above-mentioned purpose, rotation of the present invention and the jig of automatic telescopic, comprising: jig shell, jig head and conical screw.Described jig head comprises the first jig head and the second jig head that are oppositely arranged, described first jig head is provided with the first negative thread and the second negative thread from top to bottom, described second jig head is provided with the 3rd negative thread and the 4th negative thread from top to bottom, and described first negative thread and described 3rd negative thread are arranged in opposite directions, are formed with the first chamber; Described second negative thread and described 4th negative thread are arranged in opposite directions, are formed with the second chamber; Wherein, described first chamber and the second chamber are taper.Described conical screw, be provided with externally threaded first cone of tool first and externally threaded second cone of tool second from top to bottom, described first cone is placed in described first chamber, and described second cone is placed in described second chamber; Described first outside thread engages with described first negative thread and the 3rd negative thread, and described second outside thread engages with described second negative thread and the 4th negative thread; And the length of described first negative thread and the 3rd negative thread is all greater than described first outside thread, the length of described second negative thread and the 4th negative thread is all greater than described second outside thread; Wherein, described first jig head, be provided with retracing spring between described second jig head and described jig shell; And between the bottom of described jig shell and described first jig head and described second jig head, there is gap.
Rotation of the present invention and the jig of automatic telescopic, the quantity of wherein said retracing spring is 2.
The invention difference from existing technology is that the present invention achieves following technique effect: when conical screw rotates, and the first jig head and the second jig head are opened automatically.When conical screw contrarotation, make the first jig head and the second jig head automatic drawing back, utilize this function can locked rear movement and lifting by weight porose for centre, particularly also can realize at narrow space.Do not need manual operation, safety is good.
Below in conjunction with accompanying drawing, to rotation of the present invention, the jig of automatic telescopic is described further.

Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
Refer to shown in Fig. 1 and Fig. 2, for rotating and the structural representation of the jig of automatic telescopic in one embodiment of the invention, it comprises: jig shell 1, jig head and conical screw 3.Jig head comprises the first jig head 21 and the second jig head 22 be oppositely arranged, first jig head 21 is provided with the first negative thread 211 and the second negative thread 212 from top to bottom, second jig head 22 is provided with the 3rd negative thread 221 and the 4th negative thread 222 from top to bottom, and the first negative thread 211 and the 3rd negative thread 221 are arranged in opposite directions, are formed with the first chamber; Second negative thread 212 and the 4th negative thread 222 are arranged in opposite directions, are formed with the second chamber; Wherein, the first chamber and the second chamber are taper.
Conical screw 3, the second cone 32, first cone 31 of the first cone 31 and tool second outside thread 322 that are provided with tool first outside thread 311 is from top to bottom placed in described first chamber, and the second cone 32 is placed in described second chamber; First outside thread 311 engages with the first negative thread 211 and the 3rd negative thread 221, and the second outside thread 322 engages with the second negative thread 212 and the 4th negative thread 222; And the length that the length of the first negative thread 211 and the 3rd negative thread 221 is all greater than the first outside thread 311, second negative thread 212 and the 4th negative thread 222 is all greater than the second outside thread 322; Wherein, retracing spring 4 is provided with between the first jig head 21, second jig head 22 and jig shell 1; And between the bottom of jig shell 1 and the first jig head 21 and the second jig head 22, there is gap d.
In this embodiment, the quantity of retracing spring is 2, namely between the first jig head 21 and jig shell 1 and between the second jig head 22 and jig shell 1, respectively arranges a retracing spring.
When conical screw 3 clickwise, conical screw 3 moves downward relative to jig head, and jig head opens under the effect of conical screw 3.Making jig head and weight combine jig head just because of this tension force can by weight pull-up, play effect that is mobile and carrying heavy goods.
When conical screw 3 left-hand revolution, conical screw 3 is relative to jig head upward movement, and jig head shrinks and is close together under the effect of return spring force.Such jig head can be thrown off with weight.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
