[0016] Figure 2 It is a sectional view of the utility model. DETAILED DESCRIPTION

[0017] The utility model is described in detail below in combination with the drawings and specific embodiments.

[0018] Please refer to Figure 1 , Figure 2 The utility model provides a circular connector buckle structure, which comprises a socket shell 2 and a plug shell 1 that are inserted into each other, the plug shell 1 is respectively hingedly provided with an elastic pushing piece 3 and a lock piece 4, one end of the elastic pushing piece 3 is movably connected with the lock piece 4, an elastic resetting piece 5 is connected between the elastic pushing piece 3 and the plug shell 1, the elastic resetting piece 5 continuously generates a pushing force to push the end of the elastic pushing piece 3 connected with the lock piece 4 downwards, so that the lock piece 4 is compressed on the socket shell 2. When the male and female ends of the connector are inserted and connected, the plug shell 1 and the socket shell 2 are inserted and matched. When being inserted, the elastic resetting piece 5 continuously generates a pushing force to the elastic pushing piece 3, thereby pushing the lock piece 4 to compress the socket shell 2, so as to realize the locking and fixing between the socket shell 2 and the plug shell 1. The buckle structure provided by the utility model can effectively provide locking effect, and has simple structure and can meet the locking requirement without occupying too much space. When it is needed to separate the socket shell 2 and the plug shell 1, the end of the elastic pushing piece 3 away from the lock piece 4 is pushed, so that the lock piece is separated from the socket shell 2, and the male and female ends of the connector can be separated, which is convenient to operate.

[0019] In some embodiments, the socket shell 2 is provided with a locking groove 21 corresponding to the locking piece 4, and the elastic pushing piece 3 pushes the locking piece 4 into the locking groove 21 under the pushing of the elastic reset piece 5. When the plug shell 1 and the socket shell 2 are plugged into the position corresponding to the locking piece 4 and the locking groove 21, the elastic pushing piece 3 rotates around the hinge position under the pushing of the elastic reset piece 5, so as to push the front end of the locking piece 4 into the locking groove 21. At this time, if the plug shell 1 and the socket shell 2 are to be separated, the front end of the locking piece 4 is limited by the side wall of the locking groove 21, so as to avoid the locking piece from being separated from the locking groove 21, thereby achieving the locking and fixing effect.

[0020] In some embodiments, the elastic reset piece 5 is a spring, which is arranged at the end of the elastic pushing piece 3 away from the locking piece 4, and one end of the spring is in contact with the plug shell 1 and the other end is in contact with the elastic pushing piece 3. When the end of the elastic pushing piece 3 away from the locking piece 4 is pressed, the spring is compressed to accumulate elastic potential energy. After the elastic pushing piece 3 is released, the elastic potential energy of the spring is converted into kinetic energy, so as to push the elastic pushing piece 3 to rotate around the hinge shaft, thereby pushing the locking piece into the locking groove 21, and meeting the locking and fixing requirement of the socket shell 2 and the plug shell 1. In some optional embodiments, the distance between the position where the spring is in contact with the elastic pushing piece 3 and the hinge shaft of the elastic pushing piece 3 is greater than the distance between the connection position of the elastic pushing piece 3 and the locking piece and the hinge shaft of the elastic pushing piece 3, so as to increase the pushing force applied to the locking piece by the lever principle, thereby ensuring the stability of the locking state between the plug shell 1 and the socket shell 2.

[0021] In some embodiments, the plug shell 1 is provided with a plug placing groove 11 corresponding to the spring, and the elastic pushing piece 3 is provided with a pushing piece placing groove 31 corresponding to the spring, and the two ends of the spring are embedded in the plug placing groove 11 and the pushing piece placing groove 31 respectively. The two ends of the spring are guided by the plug placing groove 11 and the pushing piece placing groove 31, so as to ensure that the spring does not deviate during compression and rebound, thereby affecting the pushing effect of the elastic pushing piece 3. At the same time, since the spring has a certain length when being compressed, the spring is accommodated by the plug placing groove 11 and the pushing piece placing groove 31, so as to make the elastic pushing piece 3 and the plug shell 1 as close as possible during compression of the spring, thereby effectively reducing the space occupied by the overall structure.

[0022] In some optional embodiments, a plug rod is arranged in the plug placing groove 11 and the pushing piece placing groove 31, and the outer diameter of the plug rod matches the inner diameter of the spring, so as to effectively fix the spring and further prevent the spring from jumping or deviating.

[0023] In some embodiments, the elastic reset member 5 is a torsion spring arranged on one or both sides of the elastic push member 3, one end of the torsion spring is connected to the plug shell 1, and the other end is connected to the elastic push member 3. When the elastic push member 3 is pressed away from the one end of the locking member 4, the torsion spring is compressed and twisted to accumulate elastic potential energy. When the elastic push member 3 is released, the elastic potential energy of the torsion spring is converted into kinetic energy to drive the elastic push member 3 to rotate around the hinge shaft, thereby pushing the locking member into the locking groove 21 to meet the locking and fixing requirements of the plug shell 1 and the socket shell 2.

[0024] In some embodiments, the one end of the elastic push member 3 towards the locking member 4 is in a U-shaped structure, a guide column is arranged on the inside of the open front end of the U-shaped structure, and a guide groove is arranged on both sides of the locking member 4 corresponding to the guide column. The guide column is inserted into the guide groove and moves along the guide groove. During the rotation of the elastic push member 3 around the hinge shaft, the relative positions of the end of the elastic push member 3 and the end of the locking member 4 change. If the ends of the elastic push member 3 and the locking member 4 are simply hinged, self-locking may occur between the elastic push member 3 and the locking member 4 during the rotation of the elastic push member 3, affecting the movement state between the elastic push member 3 and the locking member 4 and the locking state between the plug shell 1 and the socket shell 2. By arranging the guide column and the guide groove, the end of the elastic push member 3 and the end of the locking member 4 can move relatively within a certain range during the pushing of the locking member 4, thereby avoiding self-locking during the rotation of the elastic push member 3 and effectively ensuring the locking state between the plug shell 1 and the socket shell 2.

[0025] In some embodiments, a limiting rod 32 is arranged on the one end of the elastic push member 3 away from the locking member 4, and a limiting groove 12 is arranged on the plug shell 1 corresponding to the limiting rod 32. The limiting rod 32 is movably inserted into the limiting groove 12 to limit the pressing distance of the elastic push member 3. When the elastic push member 3 is pressed, the limiting rod 32 moves towards the depth of the limiting groove 12 and is in contact with the bottom of the limiting groove 12 when the limiting rod 32 is pressed further, thereby limiting the further movement of the elastic push member 3 and providing a limiting effect to prevent the elastic push member 3 from being pressed too much and causing damage to the locking member or the elastic push member 3.

[0026] In some optional embodiments, the buckle structure is symmetrically arranged on both sides of the plug shell 1 to improve the stability of the locking state and prevent the plug shell 1 and the socket shell 2 from being accidentally separated.

[0027] In summary, the utility model discloses a spring reset piece to the elastic pusher continues to produce the thrust, to push the lock catch to the socket shell and carry out the compression, to realize the lock catch fixed between the socket shell and the plug shell.

[0028] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement and improvement etc. that are made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
