Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the utility model discloses a connecting pin body 3, connecting pin body 3 central point puts and is equipped with fixed block 4. One end of the fixed block 4 is provided with a first clamping mechanism, and the other end of the fixed block 4 is provided with a second clamping mechanism. As shown in fig. 2, the first engaging mechanism includes a spring 5, a connecting claw 2, a guide bush 6, and a nut 7. The connecting pin body 3 is sleeved with a spring 5, a connecting claw 2 and a guide sleeve 6 in sequence. Be equipped with jack catch 1 on connecting claw 2, jack catch 1 has four and encircles the central axis distribution of connecting claw 2. One end of the spring 5 is contacted with the end surface of the fixed block 4, and the other end of the spring 5 is contacted with the end surface of the connecting claw 2. The guide sleeve 6 is in a circular truncated cone shape. The connecting pin body 3 is provided with a step, and one end face of the guide sleeve 6 is abutted against the step. The connecting pin body 3 is provided with threads at two ends, and the connecting pin body 3 is connected with the nut 7 through the threads and fixes the guide sleeve 6 on the connecting pin body 3. The first clamping mechanism and the second clamping mechanism have the same structure and are symmetrically distributed. As shown in fig. 1 and 3, during installation, the connecting claw 2 on the first clamping mechanism is retreated to the direction of the fixed block 4 by bare hands, the claw 1 on the connecting claw 2 is separated from the guide sleeve 6, then the connecting claw 2 is directly inserted into the first corrugated pipe 8, the connecting claw 2 automatically resets under the action of the spring 5, the guide sleeve 6 is contacted with the claw 1 and props the claw 1 open outwards, and the claw 1 is fastened with the first corrugated pipe 8 and cannot slide out; and finally, the second clamping mechanism is installed and connected with the second corrugated pipe 9, the installation process is the same as that of the first corrugated pipe 8, the first corrugated pipe 8 is quickly connected with the second corrugated pipe 9, and the plastic coating process is convenient to carry out.
The utility model has the advantages of quick connection, convenient use, firm connection, convenient taking-off after the extrusion molding is finished and long service life.
The above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereby. Those skilled in the art will appreciate that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention. The scope of the invention is defined by the claims and their equivalents.
