The present invention relates to a belt buckle for joining two sections of conveyor belts. More particularly, the present invention relates to a belt buckle that generally has a U-shaped cross-section that is clamped on both sides of the ends of the two-segment belt and then joined by a pin that acts on the belt buckle Toothed hinge part.
By means of a U-shaped rivet or a wire staple, the belt buckle can be clamped and fixed at the construction site, and both ends of the rivet or the staple are pressed through the small hole of the first arcuate portion of the buckle, and then After passing through the conveyor belt, the staples then pass through the apertures in the other arcuate portion of the belt buckle. The stapler can be used to drive the staple into the belt, and the punching device continuously acts on the head of each of the staples, during which the buckle is supported on the support member, the support member effectively acts as an iron The role of the drill. The support member has a recess for receiving the tip of the staple so that the staple can be bent and the staple is pressed against the corresponding curved portion of the buckle.
In order to ensure that the belt buckle can be securely fixed at the construction site, a punching device or a punching machine must be used. This punching device can generate high pressure and form beads between the tip of the staple and the belt buckle. Shaped connection. This requires the use of more complex and more expensive equipment.
Accordingly, it is an object of the present invention to provide a belt buckle for attaching a belt that is designed to allow the belt buckle to be secured in the field without the need for a punch that must be used in the prior art.
In order to attain the above object of the present invention, the present invention provides a belt buckle for connecting a conveyor belt, which is connected by two rows of oppositely arranged belt buckles, the belt buckle comprising a toothed hinge portion which can be connected The pin pins are connected, each belt buckle is substantially U-shaped, so that the belt buckle can be hinged on both sides of the edge of the conveyor belt, and can be pressed with a U-shaped wire made of U-shaped wire, the tip of the staple The head can be pressed through the aperture of each belt buckle bow portion and through the belt between the two arcuate portions, in accordance with the present invention, the tip of the fixed staple can be received at the rear of the arcuate portion of each belt buckle Each of the small holes disposed opposite the tip of the staple is connected to the other small hole through a groove or the like outside the arcuate portion, and the corresponding tip can pass through the small hole to press it Return to the belt buckle and press it into the belt again or between the belt and the bow of the belt buckle. During the punching and clamping of the field staples, bend the staple head and face the iron supporting the belt buckle Drilling pair of staples When pressurized, some actions can be automated. A belt buckle is supported on the iron drill.
Since the pointed end of the staple is worn back into the buckle, the tip is locked, rather than remaining in the bent state outside the arcuate portion of the buckle. Therefore, the belt buckle of the present invention can be reliably clamped on site without bending the tip of the staple with a large pressure. The clamping belt can use a very simple perforating device which is also part of the invention.
The device comprises a perforating head which can be manually operated by means of a hammer or similar tool and an iron bar or similar tool which can be effectively used as an iron drill. Such a tool which acts as an iron drill when fixing the belt buckle The belt buckle can be clamped. The iron bar according to the present invention has a spaced apart boss, which is also a device for positioning the belt buckle to be clamped, and has a seat for accommodating the manual positioning device, and a perforated head for the stapled staple In the positioning device, an iron bar can be effectively used as an iron drill. To accommodate the staples of the staples, the bars have an arc shape in which the staples can be bent to pass through the apertures and to place the staples in corresponding arcuate portions of the buckle.
According to another feature of the connecting belt buckle of the present invention, the access holes and the exit holes for guiding the curved portion of the staples on the belt buckle bow portion are arranged obliquely to avoid being disposed on the same axis of the conveyor belt. This ensures that the strength on the axis is not weakened, and that the weaker axis of the force can quickly cause damage to the entire conveyor belt.
Another feature of the belt buckle according to the present invention is that a groove or the like for receiving the staple head on the outer surface of the arcuate portion extends at a right angle, i.e., in a direction perpendicular to the position line of the connecting shaft pin, so as to be worn. The pointed ends of the staples or the like are arranged on the same axis of the conveyor belt. When the belt runs over the guide roller and the drive roller or the like, the tip of the staple is not subjected to the separating force.
