Screen securing device
A securing device for securing a screening panel to a support frame of a vibrating screen assembly. The securing device has a body with a securing means at one end and a stub at the lower end. The securing means is shaped to mate with a complementary securing cavity in the screening panel and has a hole that receives a pin located in the securing cavity. The stub may be threaded to engage the support frame.
1. A securing device for holding a screening panel to a support frame of a vibrating screen assembly comprising:
a body;
a securing means at an upper part of the body comprising a first shape corresponding with a complementary securing cavity on the screening panel;
a hole formed in the upper part of the body adjacent the securing means comprising a second shape corresponding with a pin of the screening panel; and
a stub at a lower part of the body comprising a third shape corresponding with a corresponding socket in the support frame; and
wherein the securing means comprises a tapered neck and an enlarged head at the narrower end of the neck.
2. The securing device of claim 1 further comprising a flange intermediate the upper end of the body and the lower end of the body.
3. The securing device of claim 2 including a securing ridge on the flange.
4. The securing device of claim 2 wherein the flange is suitably shaped at an outer perimeter to be engaged for tightening.
5. The securing device of claim 4 wherein the flange is shaped for engagement by a tool.
6. The securing device of claim 1 wherein the securing means comprises a ridge.
7. The securing device of claim 1 further comprising a circumferential ridge at a junction of the tapered neck and the enlarged head.
8. The securing device of claim 1 wherein the securing means comprises a recess.
9. The securing device of claim 1 wherein the securing means has a donut profile.
10. The securing device of claim 1 wherein the upper part of the body comprises a neck.
11. The securing device of claim 10 further comprising a flange intermediate the upper end of the body and the lower end of the body and a collar at a junction of the neck and the flange.
12. The securing device of claim 1 wherein the hole extends through the body from the upper part to the lower part.
13. The securing device of claim 1 wherein the stub is formed as a blank in which a thread is cut by the action of screwing the securing device into the socket in the frame.
14. The securing device of claim 1 wherein the stub is threaded.
15. The securing device of claim 1 wherein the stub is tapered.
16. A system, for holding a screening panel to a support frame of a vibrating screen assembly, comprising:
