[0033] Example 1: Please refer to Figures 1-4As shown:

[0034] This invention provides a connector structure, including a duct plate 1, a folded edge 2, a connector 3, a slot 4, a guide groove 5, a sliding groove 6, a socket 7, and an installation and connection mechanism; the folded edge 2 is disposed on the side of the duct plate 1; the connector 3 is slidably connected to the outside of the folded edge 2; the slot 4 is opened on the inside of the connector 3; multiple sets of guide grooves 5 are provided, all of which are opened on the inside of the connector 3, and the guide grooves 5 are square; two sliding grooves 6 are provided, both of which are opened on the left and right sides of the connector 3; multiple sockets 7 are provided, all of which are opened on the upper end face of the folded edge 2; the installation and connection mechanism is disposed on the inside of the connector 3.

[0035] The installation and connection mechanism includes: a first inclined pin 8, a first limiting spring 9, a guide rod 10, a second inclined pin 11, a fixed shaft 12, a second limiting spring 13, a rotating component 14, a limiting pin 15, and an arc-shaped groove 16; multiple first inclined pins 8 are provided, and each first inclined pin 8 is slidably connected to the inner side of the upper end of the insert 3, and the lower end face of the first inclined pin 8 is provided with an inclined surface; multiple first limiting springs 9 are provided, and each first limiting spring 9 is fixedly connected to the upper end face of the multiple first inclined pins 8, and the upper end of the first limiting spring 9 is fixedly connected to the inner side of the insert 3; multiple guide rods 10 are provided, and each guide rod 10 is fixedly connected to the upper end face of the multiple first inclined pins 8, the guide rods 10 are square, and the guide rods 10 are slidably connected to the guide groove 5. Two second inclined pins 11 are provided, and both second inclined pins 11 are slidably connected to the inner side of the upper end of the insert 3; two fixed shafts 12 are provided, and the two fixed shafts 12 are respectively fixedly connected to the upper end face of the two second inclined pins 11, and the fixed shafts 12 are cylindrical; two second limiting springs 13 are provided, and the two second limiting springs 13 are respectively fixedly connected to the upper end face of the second inclined pins 11, and the upper end of the second limiting springs 13 is fixedly connected to the inner side of the insert 3; two rotating parts 14 are provided, and the two rotating parts 14 are respectively fixedly connected to the upper end face of the two fixed shafts 12; two limiting pins 15 are provided, and the two limiting pins 15 are respectively slidably connected to the inner side of the two rotating parts 14; two arc-shaped grooves 16 are provided, and both arc-shaped grooves 16 are opened on the upper end face of the insert 3.

[0036] With the first inclined pin 8 in place, when the insert 3 and the folded edge 2 are slidably connected, the first inclined pin 8 will retract into the inside of the insert 3. When the first inclined pin 8 coincides with the insertion hole 7, the first inclined pin 8 will be inserted into the inside of the insertion hole 7 under the action of the first limiting spring 9. The sliding connection between the guide rod 10 and the guide groove 5 realizes the guidance of the first inclined pin 8. When the insert 3 and the folded edge 2 are slidably connected, the second inclined pin 11 will be guided by the second limiting spring 13. Under the action of the pin, it is inserted into the inner side of the socket 7. With the setting of the fixed shaft 12, the second inclined pin 11 can be rotated. After the insert 3 is slid to the appropriate position, the rotating part 14 is rotated and the limiting pin 15 is pressed down so that the limiting pin 15 is inserted into the inner side of the arc groove 16 to limit the rotating part 14. At this time, the inclined surface of the second inclined pin 11 is not in the same direction as the inclined surface of the first inclined pin 8, so the insert 3 cannot be slid further, thus realizing the installation of the insert 3.

When it is necessary to disassemble the two insert strips 3, by pushing the fixing plate 23 forward, the limiting block 21 can be retracted into the inside of the insert strip 3. At this time, the combination block 19 can be slid out of the combination groove 20. Due to the setting of the combination spring 25, when the limiting block 21 is not limited, the combination block 19 will pop out under the action of the combination spring 25.
