Abstract

The utility model discloses a hinge type strong transport belt button, which is formed by stamping and bending the same piece of steel plate. One end of the steel plate is of a button groove, and the other end of the steel plate is of button hands. A buckle hand gap used for preventing the stress concentration caused by the transverse bending of the belt is arranged between the button hands. The edges of the button hands are sloped edges which can widen the crease belts of the belt and disperse the force exertion. The sloped edges connect the belt according the position of a pin hole for the mutual crossing of the button hands through a pin, and then the two belts are connected when a flexible shaft penetrates into the coincidence button groove. The utility model has the advantages of high connection intensity, dispersed stress, and long service life of the belt.

Description

Hinge strong transport belt button

The utility model relates to a kind of travelling belt button, and particularly a kind of powerful travelling belt of hinge type that is used for connection usefulness between the belt is buckled.

The belt lacer that uses on the travelling belt mostly adopts the U type to buckle now, promptly at the two end part that the U type is buckled two pin holes are arranged respectively, the U type is buckled by pin and the belt edge buckle is connected and is passed the arc end that the U type buckles by steel wire and join company with belt lacer on being connected another belt edge.In use there are many deficiencies in this belt lacer:

1, the U type is buckled, and to buckle body short, and in the stressed running of carrying, because pin and belt edge at a distance of very little, cause the vertical pulling force limit of bearing of belt to reduce, phenomenon often appears pulling in the joint that causes the U type to be buckled with belt, finally causes stopping production and keeps in repair.

2, pin is arranged too concentratedly, and density is bigger, just is difficult to repair once belt pulls, and goes to be drawn open-minded edge to reconnect if cut out again, and this will cause the belt cumulative length to shorten, and not only influence is installed, and also influences the runnability of belt.

3, for the old belt of the fire-retardant or easy back attenuation that stretches, normal appearance connects the situation loose, that connection is not firm or binding is not gone up, cause old belt not reuse, cause very big waste, its main cause is the repair function that existing BUTTON ATTACHING MACHINE does not have above-mentioned situation.

4, because the fatigue strength at pin hole place is relatively weaker, in powerful carrying and running, through bending repeatedly, the U type is buckled in the pin hole place and is easy to fracture, and threads off thereby cause belt to connect.

5, the U type is buckled along belt edge transversely arranged, form a neat backfin trace band between arrangement edge that its U type is buckled and the belt, this backfin trace band is in the running repeatedly of belt, and the power that fatigue strength and belt lacer act on the belt is too concentrated, so belt is easily ruptured at backfin trace band.

The purpose of this utility model will provide exactly that a kind of linking intensity is big, stress disperses, the fatigue strength height, not only is suitable for new band, and the powerful travelling belt of hinge type that also is suitable for old band is buckled.

The powerful travelling belt button of hinge type is achieved in that by the good steel plate of punching press is curved and is pressed into the groove shape that the side is the U type, and its end is a catching groove, and the catching groove side projection is circular-arc, and two flat boards that stretch out at the catching groove two ends are the attacker, connect belt with it.On two flat boards of attacker an attacker crack is arranged respectively, be the interval of certain width, it mainly is in order to alleviate the influence of the operating travelling belt transverse bending cause of carrying to belt lacer.One group of pin hole is respectively arranged on the attacker of both sides, attacker crack, and the center of pin hole is staggered, and the interaction force that each pin is connected with belt disperses, and can strengthen join strength, improves working life.Attacker's ora terminalis respectively have one with the hypotenuse of catching groove axis tilt, it is to overcome the backfin trace band that former belt lacer produces belt that this hypotenuse mainly acts on, hypotenuse makes the attacker widen the backfin trace band of belt, the stressed dispersion of backfin is so can prolong the working life of belt.

Attacker of the present utility model lengthening, widen, become the pin that U type in the past buckles and vertically arrange to laterally arranging, it is big that its connects area, so join strength also increases the rising of the pulling force limit thereupon; The center of the pin on the attacker is staggered, and the power that pin acts on the belt is disperseed, so can improve the join strength of belt; The distance at pin hole on the attacker who widens and attacker edge can improve the fatigue strength of attacker at the pin hole place; The attacker makes hypotenuse in the edge, has widened, disperseed belt lacer to act on backfin trace band and active force on the belt, can prolong the working life of belt.

Below in conjunction with accompanying drawing the utility model is described in further details.

Fig. 1 looks schematic representation for the utility model master.

Fig. 2 is the A-A stagewise cutaway view schematic representation of the utility model Fig. 1.

Fig. 3 connects schematic representation for the utility model.

With reference to Fig. 1, Fig. 2.The powerful travelling belt button of hinge type is by catching groove (1), attacker (2), (12), pin hole (3), countersunk head platform (5) and attacker crack (7) formation.Catching groove and attacker are same steel plate, form catching groove and attacker through curved around the back, and the axis projection of catching groove (1) is the half slot shape, and attacker (2) respectively is two flat boards with attacker (12) and is parallel to each other.Catching groove (1) is in the non-side that is connected with belt of attacker.Catching groove (1) is the interruption shape, and an interval (11) that can coincide with the catching groove of the powerful travelling belt button of another hinge type is arranged between catching groove and the catching groove, and catching groove quantity is 1～6 and evenly distributes.

Respectively there is an attacker crack (7) at middle part on attacker (2) and attacker (12).Attacker crack (7) one ends are opening-like, and the attacker edge of attacker crack opening one side has a hypotenuse (6), (8) respectively, and this hypotenuse (6), (8) are parallel to each other and catching groove axis (10) inclination relatively.The attacker is when belt running or carrying running, and alternating bending can take place the plane of structure of belt, like this attacker stress will to occur concentrated, fatigue limit to be reached, the attacker will fracture.The effect that stress disperses is played at this in the attacker crack.The main effect of hypotenuse (6), (8) is to overcome the backfin trace band that former belt lacer produces the effect of belt.Hypotenuse makes the attacker widen the backfin trace band of belt, and the stressed dispersion of backfin is so can prolong the working life of belt.

Pin hole (3) distributes on the attacker on both sides, attacker crack, per two pin holes (3) are in the same countersunk head platform (5), the center of pin hole is staggered, its staggered purpose just is to disperse the active force of pin to belt, prevent concentration of local or be on the same line, otherwise belt is will be along pin many and be in the weakness band fracture on the same line or chip.For the ease of installing, respectively have one consistently with attacker's side circular arc (4), (9) direction at attacker crack dual-side, equirotal circular arc has had circular arc to be unlikely when mounted with the utility model dress instead.

During installation, the belt ora terminalis is placed between attacker (2) and the attacker (12), utilize BUTTON ATTACHING MACHINE that the U sprig is pressed into along pin hole, and as the stapler principle, detain banding from attacker's another side back of the body, the powerful travelling belt button of the hinge type of two leash end that will connect then connects by flexible axle.
