DETAILED DESCRIPTION

[0028] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so that the realization process of how the present application applies technical means to solve technical problems and achieves technical effects can be fully understood and implemented.

[0029] Please refer to Figures 1 to 5 The embodiment of the utility model provides a quick connecting piece with guide structure, including first flange plate 1 and second flange plate 2, the bottom fixed connection of first flange plate 1 has extrusion block 101, and the arc-shaped sliding groove 105 and notch 106 are set up on first flange plate 1, and the arc-shaped sliding groove 105 is linked with notch 106, and the bottom fixed connection of second flange plate 2 has connecting block 201, and the bottom of connecting block 201 is provided with flange 202, and flange 202 penetrates notch 106 and stretches to the below of first flange plate 1, then rotates second flange plate 2, and connecting block 201 is rotated to arc-shaped sliding groove 105 from notch 106, so that flange 202 is resisted at the bottom of extrusion block 101, the inside of first flange plate 1 is provided with center insertion hole 104, and the inside fixed connection of second flange plate 2 has center insertion block 204, and second flange plate 2 is concentric with center insertion hole 104, and second flange plate 2 is concentric with center insertion block 204, and center insertion block 204 is inserted in center insertion hole 104, and the bottom of center insertion block 204 exceeds flange 202 bottom.

[0030] When connecting, center insertion block 204 is inserted into center insertion hole 104, so that first flange plate 1 and second flange plate 2 are primarily connected, then rotate second flange plate 2, and flange 202 is rotated to the place of notch 106, and flange 202 of second flange plate 2 is inserted from notch 106, because the bottom of center insertion block 204 exceeds flange 202 bottom, in the process of inserting, center insertion block 204 is inserted into center insertion hole 104 first, plays a primary guide role, and reduces the difficulty of manual alignment. When flange 202 passes through notch 106, rotate second flange plate 2, connecting block 201 slides along arc-shaped sliding groove 105, finally flange 202 is resisted at the bottom of extrusion block 101, realizes locking connection, when disassembling, rotate second flange plate 2 reversely, make connecting block 201 slide back from arc-shaped sliding groove 105 to notch 106, first flange plate 1 and second flange plate 2 can be separated.

[0031] In this embodiment, the distance D between the bottom of the center plug 204 and the bottom of the flange 202 is greater than or equal to 2 mm.

[0032] Through the above arrangement, it is ensured that the center plug 204 can be inserted into the center hole 104 before the flange 202 during the connection operation.

[0033] In this embodiment, the center plug 204 is provided in a tubular shape.

[0034] The center plug 204 is provided in a tubular shape, which can reduce the overall weight and material cost on the one hand, and on the other hand, the tubular structure has good rigidity and stability, can withstand certain external force without being easily deformed when being inserted into the center hole 104, ensuring the accuracy of the guidance and the reliability of the connection, and at the same time, the tubular structure can reserve space inside, facilitating the passing of cables and other components, and expanding the use function of the connector.

[0035] Further, the bottom of the center plug 204 is provided with a chamfer 205.

[0036] The chamfer 205 at the bottom of the center plug 204 plays a guiding role, which can make the insertion process smoother and reduce the insertion resistance when the center plug 204 is inserted into the center hole 104.

[0037] In this embodiment, one end of the extrusion block 101 is provided with a guide notch 102.

[0038] The guide notch 102 on the extrusion block 101 provides guidance for the flange 202 during the rotation of the second flange plate 2, helping the flange 202 to be more accurately positioned at the bottom of the extrusion block 101. At the same time, the guide notch 102 also reduces the resistance when the flange 202 contacts the extrusion block 101, making the rotation operation more easy, and further improving the convenience of the connection.

[0039] Further, the top of the flange 202 is in frictional contact with the bottom of the extrusion block 101.

[0040] The frictional contact between the top of the flange 202 and the bottom of the extrusion block 101 can provide a certain friction force after the completion of the connection of the connector, preventing the second flange plate 2 from accidentally rotating due to vibration and other factors during use, thereby ensuring the stability and reliability of the connection and ensuring that the connector can work normally under various working conditions.

[0041] In this embodiment, the bottom of the extrusion block 101 is formed with a limiting protrusion 103, and the top of the flange 202 is provided with a positioning slot 203, and the limiting protrusion 103 can be clamped into the positioning slot 203.

[0042] When the second flange plate 2 is rotated into position, the turn-up 202 abuts against the bottom of the extrusion block 101, the limiting protrusion 103 is clamped into the positioning clamping groove 203, forming a mechanical limiting structure.

[0043] Working principle:

[0044] The center plug 204 is inserted into the center hole 104 to preliminarily connect the first flange plate 1 and the second flange plate 2, then the second flange plate 2 is rotated, the turn-up 202 is rotated to the slot 106, the turn-up 202 of the second flange plate 2 is inserted from the slot 106, after the turn-up 202 passes through the slot 106, the second flange plate 2 is rotated, the connecting block 201 slides along the arc-shaped sliding groove 105, the guide notch 102 on the extrusion block 101 assists the turn-up 202 to accurately abut against the bottom of the extrusion block 101, at the same time, the limiting protrusion 103 is clamped into the positioning clamping groove 203 to realize locking; when disassembling, the second flange plate 2 is reversely rotated to separate.

[0045] The above description shows and describes several preferred embodiments of the utility model, but as before, it should be understood that the utility model is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept disclosed herein by the above teaching or related technical or knowledge.
