Abstract
The invention discloses a tensioning connection device. The device comprises a fixed block, a lead screw and two tensioning rods, wherein a threaded hole is formed in the fixed block, internal threads of the threaded hole are matched with external threads of the lead screw, and the lead screw stretches into the threaded hole and can rotate in the threaded hole; two holes are further formed in the fixed block symmetrically in the direction of the center axis of the threaded hole, one end of each tensioning rod is movably connected with the lead screw, and the other end of each tensioning rod penetrates through the corresponding hole and protrudes out of the hole. The tensioning connection device can be used for connecting two components provided with holes or grooves from the interior of the holes or grooves.
Description
Technical field
The present invention relates to a kind of tensioning attachment means.

In accompanying drawing, the labelling of each part is as follows: 1, fixed block, and 2, hole, 3, nutted rod, 4, spin-block, 5, screw mandrel.
Specific embodiment
The enforcement it is clear that described will be clearly and completely described to the technical scheme in the embodiment of the present invention below
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of not making creative work, broadly falls into the model of present invention protection
Enclose.
Refer to Fig. 1, the embodiment of the present invention includes:
A kind of tensioning attachment means, including fixed block 1, screw mandrel 5 and two nutted rods 3, are provided with spiral shell in described fixed block 1
Pit, the female thread of described screwed hole is matched with the external screw thread of described screw mandrel 5, and described screw mandrel 5 stretches into described screw thread in the hole can
Rotate in described screw thread in the hole, in described fixed block 1, also the central axis direction along described screwed hole is symmetrically arranged with two holes 2,
One end of described two nutted rods 3 is connected with described screw mandrel 5 activity, described in the other end of described two nutted rods 3 is each passed through
Two holes 2 simultaneously protrude from outside described two holes 2.
Preferably, one end of described screw mandrel 5 protrudes from outside described fixed block 1, and described one end of described screw mandrel 5 is provided with one
Spin-block 4.
Preferably, pass through pin class parts turn formula between described one end of described two nutted rods 3 and described screw mandrel 5 even
Connect.
Preferably, the diameter with diameter greater than described two nutted rods 3 in described two holes 2.
By the outer end of two nutted rods 3 respectively close to the hole of two parts to be connected or groove inwall during use, 4 turns of stubborn spin-block
Dynamic screw mandrel 5, then screw mandrel 5 decline the inner decline driving two nutted rods 3, the outer end of two nutted rods 3 hold out against two to be connected
The hole of part or groove inwall, two parts to be connected are fastenedly connected.
The foregoing is only embodiments of the invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in the technology neck of other correlations
Domain, is included within the scope of the present invention.
