Problems solved by technology
However, the above scheme also has some shortcomings. For example, during the connection process, the split collar is supported by a spring. When the insertion rod is inserted into the split collar with too much force or at a high speed, the split collar is easy to get out of the middle hole. nut, causing the connection to fail
The above solution needs to be installed piece by piece when installing the split collar on the spring. A little carelessness will cause the card to enter the spring. The installation steps are highly professional, and the on-site staff need to undergo special training to complete the installation.

Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] like figure 1 As shown, a washer-positioned collar connector includes a plug nut 1 and a clip nut 2, the plug nut 1 is connected with a plug joint 3, and the clip nut 2 is provided with an anti-retraction Pad 4, split collar assembly 5 and intermediate nut 6, wherein the anti-retraction pad 4 is located at the bottom of the clip nut 2, the intermediate nut 6 is screwed to the clip nut 2 and the intermediate nut 6 is located above the anti-retraction pad 4 and prevents the anti-retraction The pad 4 plays a blocking role to prevent the anti-back pad 4 from breaking away from the clamping nut 2. The connection between the anti-back pad 4 and the intermediate nut 6 forms a clamping cavity 7 that can accommodate the split collar assembly 5. When the plug connector 3 is inserted into the When the middle nut 6 is in contact with the ...

The invention belongs to the technical field of construction, relates to a gasket positioning type collar connecting piece, and solves the technical problems of complex structure and unreliable connection in the prior art. The gasket positioning type collar connecting piece comprises an insertion nut and a clamping nut; the insertion nut is connected with an insertion plug; an anti-retreating pad, a split collar module and a middle nut are arranged in the clamping nut; the anti-retreating pad is positioned at the bottom of the clamping nut; the middle nut is screwed with the clamping nut, and is positioned above the anti-retreating pad; and a clamping cavity capable of accommodating the split collar module is formed in the connecting place of the anti-retreating pad and the middle nut. The gasket positioning type collar connecting piece is simple in structure, convenient for installation and reliable in connection.
Description
technical field [0001] The invention belongs to the technical field of construction, and relates to a washer positioning type collar connector. Background technique [0002] A connector is a structure that realizes the connection between two objects. The applicant previously applied for a patent for a prefabricated component connector and a butt joint structure of concrete prefabricated parts [application number: 201020550659.1], including a small nut, a plug Rod, medium hole nut, large nut, there is a hole at the bottom of the large nut, the steel rod's heading is stuck in it, the spring is located in the big nut and one end of the spring is in contact with the heading, and the other end is in contact with the split body The middle hole nut is screwed into the large nut, wherein the lower end of the middle hole nut is elastically matched with the split collar, and the brim of the middle hole nut is clamped on the end surface of the large nut; The insertion rod is an integr...
