Embodiment Construction

[0034] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present invention.

[0035] Such as Figure 1 to Figure 5 According to the inventive spirit of the present invention, a double-nut screw-type fixed connector based on an auxetic wedge is provided, wherein the double-nut screw-type fixed connector based on an auxetic wedge includes a compression bolt 1, a compression nut 2. One pulling bolt 3 and at least one fastening pin 4 .

[0036]The compression bolt 1 is hollow, and the compression bolt 1 is provided with an external t...

Abstract

A double-nut-screw type fixing connector based on stretching wedge blocks comprises a compression bolt, a compression nut, an external bracing bolt and at least one holding pin. The holding pins are movably arranged at the tail end of the compression bolt. The compression nut is connected to the compression bolt in a threaded mode. The external bracing bolt is operationally arranged in the compression bolt. When the double-nut-screw type fixing connector based on the stretching wedge blocks is not used, all holding pins do not protrude from the surface of the compression bolt; and when the double-nut-screw type fixing connector based on the stretching wedge blocks is used, the external bracing bolt outwards ejects the holding pins in the compression bolt so as to make the holding pins protrude from the surface of the compression bolt, and thus two connecting pieces are connected.

Description

technical field [0001] The invention relates to a double nut screw type fixed connector, which belongs to the technical field of fasteners, in particular to a double nut screw type fixed connector based on an auxetic wedge block, wherein the double nut screw type based on an auxetic wedge block The type fixed connector can be adapted to the connection of connecting pieces with through holes or blind holes, and the double-nut screw type fixed connector based on the auxetic wedge can be used repeatedly. Background technique [0002] Fasteners are widely used in engineering machinery, engineering construction, and machine assembly. Existing fastening technology has a variety of mechanical fastening connection methods, which can be divided into two categories according to whether the fasteners are detachable: 1. Detachable fasteners include bolt connections, key connections, pin connections, etc. 2. Non-detachable fasteners include rivet connections, welding, gluing, etc. Thes...
