The utility model discloses a concrete technical scheme does: a screen tensioning device comprises a net rack frame body, a screen, a pressing strip, a tensioning block and a tensioning bracket, wherein the net rack frame body is of a closed annular structure, the middle part of the net rack frame body is connected with the tensioning bracket through a spoke rib, the tensioning bracket is a cylindrical cavity with an opening at the upper end, and the tensioning block is longitudinally assembled in the tensioning bracket in a sliding manner; a screen is arranged above the net rack frame body or the tensioning block, an annular mounting groove is formed in the upper end face of the net rack frame body, an annular pressing strip which corresponds to the screen is arranged in the mounting groove, a screw hole is formed in the middle of the pressing strip, and a bolt or a screw which is downwards fixedly connected to the bottom of the mounting groove is arranged in the screw hole; the tensioning block comprises a tensioning main body and a movable plate, the tensioning main body and the movable plate are vertically distributed and slidably assembled in a tensioning bracket, and a jacking bolt fixedly connected with the movable plate upwards is arranged below the tensioning bracket.
Preferably, a groove is arranged below the tensioning body, and a buffer spring abutting against the upper part of the movable plate is arranged in the groove. The upper end surface of the tensioning main body is an arc-shaped end surface. An annular gasket is arranged above the net rack frame body.
The beneficial technical effects are as follows: this structure sets up the tensioning bracket in original rack framework, places rubber tensioning piece in the bracket, through adjusting the tight spiral in top, finally realizes that rubber tensioning piece shifts up and finally pushes up tight screen cloth. The utility model relates to a rational in infrastructure, simple has realized the requirement of the quick tensioning of screen cloth well, has improved screen cloth life and screening efficiency.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic top view of the present invention;
FIG. 3 is an enlarged view of FIG. 1 at A;
fig. 4 is an enlarged view of fig. 1 at B.
In the figure, 1 a net rack frame body, 2 screens, 3 pressing strips, 4 tensioning brackets, 5 screws, 6 tensioning bodies, 7 movable plates, 8 jacking bolts, 9 buffer springs and 10 spokes are arranged.
Detailed Description
The specific use example is described in detail below with reference to the accompanying drawings, the structure of the utility model is a novel screen tensioning device, which comprises a net rack frame body 1, a screen 2, a pressing bar 3, a tensioning block and a tensioning bracket 4, wherein the net rack frame body 1 is a closed annular structure, the middle part of the net rack frame body is connected with the tensioning bracket 4 through a spoke rib 10, the tensioning bracket 4 is a cylindrical cavity with an open upper end, and the interior of the cylindrical cavity is longitudinally assembled with the tensioning block in a sliding manner; the screen mesh 2 is arranged above the net rack frame body 1 or the tensioning block, an annular mounting groove is arranged on the upper end face of the net rack frame body 1, an annular pressing strip 3 which corresponds to the screen mesh 2 is arranged in the mounting groove, a screw hole is formed in the middle of the pressing strip 3, and a bolt or a screw 5 which is downwards fixedly connected to the bottom of the mounting groove is arranged in the screw hole; the tensioning block comprises a tensioning main body 6 and a movable plate 7, the tensioning degree is adjusted by upward jacking through a tensioning device, the tensioning main body 6 and the movable plate 7 are vertically distributed and slidably assembled in the tensioning bracket 4, and a jacking bolt 8 fixedly connected with the movable plate 7 upwards is arranged below the tensioning bracket 4.
This structure sets up tensioning bracket 4 in original rack framework 1, places rubber tensioning piece in the bracket, realizes through top tight bolt 8 that screen cloth 2's rate of tension is adjusted, finally realizes that rubber tensioning piece shifts up final top tight screen cloth 2. The utility model relates to a rational in infrastructure, simple has realized the requirement of the quick tensioning of screen cloth 2 well, has improved screen cloth 2 life and screening efficiency.
A groove is arranged below the tensioning main body 6, and a buffer spring 9 abutting against the upper part of the movable plate 7 is arranged in the groove. The upper end surface of the tensioning body 6 is an arc-shaped end surface. Utilize the arc terminal surface to realize reducing the damage to screen cloth 2 as far as possible under the tight regulation in top, avoid improving the utility life of screen cloth 2.
An annular gasket is arranged above the net rack frame body 1. Set up buffer spring 9, can cushion screen cloth 2, avoid high strength impact to damage screen cloth 2, annular layering 3 is fixed screen cloth 2 through bolt and annular layering 3. The spoke ribs 10 are connected with the tensioning bracket 4, so that the fixing effect is improved as far as possible on the premise that the screening efficiency of the device is not influenced.
