Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as figure 1 and figure 2 As shown, a connection nut for snap-in connectors includes a nut body 1, the nut body 1 has a ring clamping platform 2, and the ring clamping platform 2 has a ring protruding from the ring clamping platform 2. The annular collar 3, the cross section of the annular collar 3 can be in various shapes, preferably, the cross section of the annular collar 3 is rectangular.
[0018] The ring collar 3 is located on the lower surface of the ring clamp table 2 , and the inner wall of the ring collar 3 is on the same surface as the inner wall of the ring clamp table 2 . There is a guide channel 5 in the shape of an inverted frustum cone inside the ring card table 2 and away from the end of the ring collar 3. The guide channel 5 communicates with the inside of the nut body 1. The function of the guide chann...

The invention belongs to the technical field of buildings and relates to a connection nut for a clamping type connecting piece. The technical problem that adjustment is not convenient in the prior art is solved. The connection nut comprises a nut body. The nut body is provided with an annular clamping platform. The annular clamping platform is provided with an annular clamping ring protruding out of the annular clamping platform. The connection nut can be quickly connected with a connecting plug and has a positioning function. When the connection nut is matched with the connecting plug in a clamped mode, the clamped positions are connected firmly and are not liable to looseness.
Description
technical field [0001] The invention belongs to the technical field of construction and relates to a connection nut used for snap-in connectors. 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 an...
