Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 with image 3 As shown, a snap fit connector includes a plug connector 1 and a connection nut 2, the connector nut 2 has a ring-shaped ring clamping platform 21 inside, and the plug connector 1 includes a connection end 11 and a plug connector. Connecting end 12, wherein the plug-in end 12 is composed of at least three clamping columns 13 arranged circumferentially along the axis of the plug connector 1. The ends of the clamping columns 13 are expanded to form an enlarged part 14. When 14 enters the inside of the connecting nut 2, the lower surface of the annular clamping platform 21 and the upper surface of the enlarged part 14 can engage with each other so that the clamping column 13 clamps the connecting nut 2, and the annular clamping platform 21 and the upper surface of the enlarged part 14 can be engaged...

The invention belongs to the technical field of a building, and relates to a clamping matching type connecting element. The clamping matching type connecting element solves the technical problem of regulation inconvenience in the prior art. The clamping matching type connecting element comprises an inserting head and a connecting screw nut, wherein an annular clamp table in an annular shape is arranged in the connecting screw nut; the inserting head comprises a connecting end and an inserting end; the inserting end consists of at least three clamping posts ranged in the circumferential direction of an axial lead of the inserting head; the end part of each clamping post expands to form an expansion part; when the expanding parts enter the inside of the connecting screw nut, the lower surface of the annular clamp table and the upper surfaces of the expanding parts can be mutually clamped, so that the clamping posts can clamp the connecting screw nut; and a positioning mechanism enabling the annular clamp table to be clamped and matched with the expanding parts in a concave-convex way when the annular clamp table is clamped with the expanding parts is arranged on the annular clamp table and the expanding parts. The connecting element has the characteristic that the distance is adjustable. The distance can be adjusted according to different requirements, and fast connection between two prefabricated components is realized.
Description
technical field [0001] The invention belongs to the technical field of construction, and relates to a snap-fit connector. Background technique [0002] In the previous application of the applicant for the patented screw-on-bottom-top pile buckle and prefabricated part [authorized announcement number: CN100348803C], it is composed of a tension nut, a top tension nut and a longitudinal steel bar of the pipe pile located at both ends of the pipe pile. , the expansion nut and the top pull nut are internal thread structures, and the internal thread is a strong wire buckle. There is a steel bar hole in the center of the bottom of the cap. The periphery of the steel bar hole is a steel bar heading card platform. The upsetting head is clamped on the card table. The prestressed pipe pile splicing buckle is composed of an expansion nut, a top tension nut, a combined insert sleeve, an intermediate sleeve and a connecting rod, wherein the expansion tension nut and the top tension nut...
