Drawings
Fig. 1 is a schematic structural diagram of an embodiment of an elastic pulling apparatus provided in the present invention.
Fig. 2 is a schematic view of the elastic drawing device provided by the invention for locking an object to be drawn.
Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the present embodiment provides an elastic pulling apparatus, including an elastic tube 1, a locking tube 3 and a clamping joint;
the elastic tube 1 and the locking tube 3 are both of circular tube structures;
the clamping joint is connected with one end of the elastic tube 1, and the locking tube 3 is sleeved outside the elastic tube 1;
the clamping joint is used for clamping and fixing an object to be drawn, and the locking pipe 1 is used for being matched with the elastic pipe 1 to lock the object to be drawn after the clamping joint clamps the object to be drawn.
Furthermore, the locking pipe 1 is made of rigid materials, and the elastic pipe 1 is a thin-wall circular pipe.
Further, the elastic tube 1 is provided with at least two slots along the axis so that the inner diameter of the elastic tube 1 can be enlarged.
Further, the centre gripping connects including ring shape centre gripping main part 2, and the one end of ring shape centre gripping main part 2 is provided with step 21, and the other end card of ring shape centre gripping main part 2 is gone into in the elastic tube 1, with elastic tube 1 interference fit, and step 21 offsets with the tip of elastic tube 1.
Further, the inner surface of the ring-shaped holding body 2 is provided with a protrusion 22, and the protrusion 22 is used for chucking an object to be drawn.
Drawing between the object, refer to fig. 1, move back locking pipe 3 to the one end of keeping away from the centre gripping and connecting (nevertheless do not deviate from elastic tube 1), promote the overall device and remove to waiting to draw object 10, make the centre gripping and connecting to be propped open by waiting to draw object 10, as an preferred embodiment, can set up the recess on waiting to draw object 10, it continues to impel to wait to draw object 10 to prop open the centre gripping and connecting, it enters into elastic tube 1 to make to wait to draw object 10, the arch 22 card that the centre gripping connects is in waiting to draw the recess of object 10, later impel locking pipe 3 to the centre gripping and connecting the direction, until the tip of locking pipe 3 offsets with the step 21 that the centre gripping connects, locking elastic tube 1.
And then pulling out the object to be pulled by means of the elastic pulling device.
After the object to be drawn is pulled out, the locking pipe 3 is retreated to one end far away from the clamping joint, and the object to be drawn can be separated from the clamping joint.
The elastic drawing device provided by the embodiment at least comprises the following beneficial effects:
(1) the drawing device is simple in structure and high in reliability, and can be used for drawing a large cylindrical object from a long and thin space, so that time and labor are saved, and the production efficiency is improved;
(2) and the object to be drawn is simple and reliable to install and convenient to disassemble.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
