Description

Anti-falling scaffold connecting pull rod

Technical Field

The utility model relates to a scaffold frame accessory, in particular to scaffold frame connecting pull rod that anticreep goes out.

Background

The connecting pull rod of the scaffold generally adopts the following connecting heads: referring to fig. 1, the connector is a flat connector, a large through hole and a small through hole are punched on the surface of the flat connector, the large through hole and the small through hole are communicated through a linear channel, a fastener, usually a bolt and a nut, integrally penetrates through the large through hole, then moves into the small through hole through a bolt channel, and the nut is screwed in the small through hole due to the fact that the radius of the small through hole is smaller than that of the nut, and the flat connector is compressed through the nut to achieve fixing; but foretell connection structure has certain potential safety hazard, because the nut of screwing relies on manual operation, the nut probably pine takes off after repetitious usage, in case the pine takes off, the bolt directly landing is to the big perforation in, causes scaffold overall structure to collapse, the incident appears easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve one of the technical problem that exists among the prior art at least, provide a scaffold puts up connecting rod that prevents deviating from, can prevent that the fastener from deviating from.

The utility model provides a scaffold puts up connecting pull rod that anticreep goes out, including the body of rod and the connector of setting at body of rod both ends, the connector includes big perforation, little perforation and anticreep portion, big fenestrate radius is greater than little fenestrate radius, anticreep portion sets up will between big perforation and the little perforation big perforation is separated with little perforation, big perforation and little perforation are in through a setting the other installation passageway intercommunication of anticreep portion, anticreep portion supports the top fastener and prevents that the fastener from following little perforation is deviate from the straight line and is arrived big perforation.

The anti-disengaging scaffold connecting pull rod at least has the following beneficial effects: the fastener wholly penetrates big perforation to in the installation passageway removes little perforation, because not straight line intercommunication between big perforation and the little perforation, consequently even the fastener takes off from little perforation, also can be withstood by anticreep portion, can not deviate from to the big perforation by the straight line, consequently can keep the overall structure of scaffold frame, reduce the emergence of incident.

Further, according to the utility model relates to a scaffold puts up connecting rod that anticreep goes out, the installation passageway includes first passageway and second passageway, first passageway and second passageway are not on same straight line, first passageway intercommunication the big perforation, the second passageway intercommunication little perforation. Since the separation preventing portion separates the large through hole and the small through hole, the installation passage bypasses the separation preventing portion to communicate the two through holes, thereby forming a first passage and a second passage which are connected.

Further, according to the utility model relates to a scaffold puts up connecting rod that anticreep goes out, first passageway and second passageway are mutually perpendicular, the junction of first passageway and second passageway is the fillet. For the right-angle bent installation channel, the fastener needs force in at least two directions for releasing, and the connection pull rod usually only has force in the axial direction or the angle near the axial direction, so the right-angle bent installation channel can effectively prevent the fastener from releasing.

Further, according to the utility model a scaffold puts up connecting rod that anticreep goes out, an limit of first passageway with it is tangent to bore greatly, an limit of second passageway with it is tangent to bore for a short time. In order to ensure that the fastener moves smoothly in the installation channel, the channel is smooth in a tangent mode, and the installation is convenient.

Further, according to the utility model relates to a scaffold puts up connection pull rod that anticreep goes out, big perforation and little perforation are pressed the length direction of the body of rod distributes, the length direction of first passageway with the length direction of the body of rod is the same. The length direction of the second channel is equal to the length direction of the rod body, the length direction of the second channel is perpendicular to the length direction of the rod body, and the second channel is abutted to the small through hole, and the fastener penetrates into the small through hole to be fastened, so that the fastener is not easy to slip into the first channel even if the fastener is separated.

Further, according to the utility model relates to a scaffold puts up connection pull rod that anticreep goes out, the connector is flat joint, the connector with the body of rod integrated into one piece, the connector is gone out by stamping equipment punching press after flattening big perforation, little perforation and installation passageway. The thickness of the flat joint is the thickness of two layers of rod body walls, and the structure is firmer.

Referring to fig. 2 and 3, an embodiment of the present invention relates to an anti-slip scaffold connecting rod, including a rod body 1 and connectors 100 disposed at two ends of the rod body 1, the connectors 100 include a large perforation 110, a small perforation 120 and an anti-slip portion 130, a radius of the large perforation 110 is greater than a radius of the small perforation 120, the anti-slip portion 130 is disposed between the large perforation 110 and the small perforation 120 to separate the large perforation 110 from the small perforation 120, the large perforation 110 and the small perforation 120 are communicated through an installation channel 140 disposed beside the anti-slip portion 130, and the anti-slip portion 130 supports a fastener to prevent the fastener from being linearly released from the small perforation 120 to the large perforation 110.

In this embodiment, referring to fig. 3, the fastener is exemplified by a bolt 2 and a nut 3, wherein the diameter of the external screw rod 4 in the bolt 2 is smaller than the width of the installation channel 140, the radius of the head 5 of the bolt 2 and the outer diameter of the nut 3 are both larger than the radius of the small through hole 120 and smaller than the radius of the large through hole 110, when installing, the fastener integrally penetrates the large through hole 110, the large through hole 110 is located between the head 5 of the bolt 2 and the nut 3, then the fastener enters the small through hole 120 along the installation channel 140, and by screwing the nut 3, the head 5 of the bolt 2 and the nut 3 form a clamping structure on both sides of the small through hole 120, thereby being fixed.

The installation channel 140 includes a first channel 141 and a second channel 142, the first channel 141 and the second channel 142 are not in the same line, the first channel 141 communicates with the large through hole 110, and the second channel 142 communicates with the small through hole 120. Regarding the shape of the mounting channel 140, it is preferable that the first channel 141 and the second channel 142 are perpendicular to each other, and a junction of the first channel 141 and the second channel 142 is rounded. In addition to the right-angled bending, other bending forms such as obtuse-angled bending may be used, and at this time, the shape of the anti-slip part 130 is changed accordingly while the anti-slip function is maintained. The utility model discloses connector 100 is flat joint, connector 100 and body of rod 1 integrated into one piece, and connector 100 is through flattening the back by stamping equipment punching press out big perforation 110, little perforation 120 and installation passageway 140, consequently according to the shape of punching press different, and anticreep portion 130's shape is also different.
