CONNECTOR FOR CONVEYOR BELTS

Abstract

A connector for conveyor belts includes, installed on both sides of a conveyor belt, a pair of plates having protrusions on the inner surface thereof, which are tightened by a bolt and nut and by a removable elastic ring capable of being secured on the body of the bolt. In the present embodiment, one plate is provided with a polygonal through-hole having a mounting seat for the head of the bolt, which bolt has a securing portion below the head thereof, the securing portion corresponding to the polygonal hole, and the other plate is provided with a mounting seat for the nut, which nut is carried out with a slot on an end thereof. In certain embodiments, the bolt head is flat, the bolt shank is conical, and the nut is hexagonal. The plates may have through-holes disposed between the protrusions on the inner surfaces of the plates.

Claims

1. A connector for conveyor belts, including a pair of plates mounted on both sides of the conveyor belt, each of which has protrusions on the inner surface of the plates, tightened with a bolt and nut, characterized in that a through-hole polygonal hole with a socket for the bolt head the bolt under the head has a fixing part, made corresponding to a through polygonal hole, the other plate has a mounting seat under the nut, which is made with a slot on the end and additionally includes there is a removable elastic ring made with the possibility of its fixation on the body of the bolt.

2. Connector for conveyor belts according to claim 1, characterized in that the through hole with a landing slot for the bolt head is made quadrangular.

3. Connector for conveyor belts according to claim 1, characterized in that the bolt head is made flat.

4. Connector for conveyor belts according to claim 1, characterized in that the shank of the bolt is tapered.

5. Connector for conveyor belts according to claim 1, characterized in that the plates additionally have through holes located between the protrusions.

6. Connector for conveyor according to claim 1, characterized in that the nut has a hexagonal shape.

Description

[0017] FIG. 2 shows a top view of the bottom plate of the connector for conveyor belts.

[0018] FIG. 3 is a side view of the bottom plate of the connector for conveyor belts.

[0019] FIG. 4 shows a top view of the top plate of the connector for conveyor belts.

[0020] FIG. 5 is a side view of the top plate of the connector for conveyor belts.

[0021] FIG. 6 shows the connector bolt for conveyor belts.

[0022] FIG. 7 illustrates the connector nut for conveyor belts.

[0023] The drawings d the description of the implementation and use of the connector for conveyor belts in no way limit the scope set forth in the claims, but merely illustrate the essence of the invention.

[0024] Connector for conveyor belts consists of a lower plate and upper plate 2, bolt 3, the elastic ring nut 4 and 5.

[0025] The bottom plate 1 is formed with a through hole 6 polygonal (quadrangular in this case) bolt 3. The upper plate 2 is formed with a through hole 7 with a seat 8 for the nut 5. The bolt has a head fixing portion 9, in this case quadrangular cross section, which corresponds quadrangular through hole 6 in the bottom plate, and a tapered shank 10.

[0026] The elastic ring 4 has an internal diameter, whose size enables easily and securely fix it to the body of the bolt 3 and the nut 5 has a slot 11 at the end of a special spanner. The nut may be made hexagonal shape (FIG. 7), allowing during assembly using a simple hex wrench.

[0027] Lower plate 1 and upper plate 2 is formed with protrusions on the inner surfaces of the plates and may have through holes between the projections.

[0028] Compound Conveyor belts closed type connector is as follows.

[0029] Rubber-belt portion is folded so that cut edges are superposed one on one. On the inner plate of the conveyor belt and mark out holes are punched. Quadrangular locking portion of each bolt has a correspond rectangular holes in the bottom plate, the lower surface of the head of the bolt abuts the surface of the receiving hole, so that the upper flat surface of the bolt head does not protrude above the surface of the plate. Below each opening in the belt is inserted a bolt previously wound into the hole of the bottom plate. Thereafter, a bolt wear elastic ring which holds the plate on the conveyor belt with a bolt. On the outer lining of the conveyor belt superimposed upper plate, so that a bolt passed through the hole of the upper plate.

[0030] The proposed connector for conveyor belts can quickly and conveniently make the connection conveyor belts gated and provide increased service life of rubber bands.
