DETAILED DESCRIPTION

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-5 A communication electronic printed circuit board shown in the figure comprises a printed circuit board body 1, wherein the four corners of the printed circuit board body 1 are sleeved with a limit sleeve 2, a mounting rod 3 is installed at the bottom of the limit sleeve 2 by screws, a mounting tube 4 is sleeved at the bottom end of the mounting rod 3, a square hole 9 is opened on the side of the mounting tube 4, a mounting groove 13 corresponding to the position of the square hole 9 is opened on the side of the mounting rod 3, a plurality of second mounting holes 12 connected with the mounting groove 13 are opened on the side of the mounting rod 3, a first sliding rod 14 is slidably inserted in the interior of the plurality of second mounting holes 12, one end of the plurality of first sliding rods 14 extends into the mounting groove 13, an inclined block 11 is installed between one end of the plurality of first sliding rods 14 by screws, one end of the inclined block 11 passes through the mounting groove 13 and extends into the square hole 9, a second compression spring 19 is movably sleeved on the surface of the plurality of first sliding rods 14, and the two ends of the second compression spring 19 are respectively installed on the side of the inclined block 11 and the inner side of the mounting groove 13 by screws. When disassembling the printed circuit board in the communication electronic equipment, first push The inclined block 11 is moved. After the inclined block 11 is subjected to force, it pushes the first sliding rod 14 to slide in the second mounting hole 12. The inclined block 11 moves from the square hole 9 to the mounting groove 13. At the same time, the inclined block 11 is subjected to force to squeeze the length of the second compression spring 19 to shrink. At this time, the inclined block 11 will not limit the movement between the mounting rod 3 and the mounting tube 4. After the four inclined blocks 11 are all moved out of the four square holes 9, the printed circuit board can be pulled, and the printed circuit board can pull the four mounting rods 3 out of the four mounting tubes 4, which is convenient for the disassembly of the printed circuit board. Operation: When installing the printed circuit board in a communication electronic device, just press the inclined block 11. After the inclined block 11 moves to the mounting groove 13, the mounting rod 3 can be inserted into the mounting tube 4. At the same time, the second compression spring 19 pushes the inclined block 11 against the inner side of the mounting tube 4. As the mounting rod 3 continues to move to one side of the square hole 9, the inclined block 11 is not blocked by the inner side of the mounting tube 4. The inclined block 11 is affected by the second compression spring 19 and moves into the square hole 9, fixing the position between the mounting rod 3 and the mounting tube 4.

[0020] A sliding groove 17 is provided on the surface of the first sliding rod 14, and a limit block 16 is installed inside the sliding groove 17 for sliding movement. One end of the limit block 16 is installed on the inner side of the mounting groove 13 by a screw. When the second compression spring 19 is not under force and is extended, the second compression spring 19 pushes the inclined block 11 to move toward the square hole 9. After the inclined block 11 is under force, it drives the first sliding rod 14 to move. After the first sliding rod 14 is under force, the sliding groove 17 slides on the limit block 16. When the inclined block reaches the moving stroke and cannot move, the side surface of the limit block 16 contacts with the end of the mounting groove 13 to prevent the first sliding rod 14 from sliding out of the second mounting hole 12, thereby improving the stability of the movement of the inclined block 11.

[0021] A fixing tube 10 corresponding to the position of the square hole 9 is provided on one side of the mounting tube 4, a third connecting rod 18 is installed on the side of the fixing tube 10 by screws, one end of the third connecting rod 18 is installed on the side of the mounting tube 4 by screws, a second sliding rod 20 is slidably inserted inside the fixing tube 10, one end of the second sliding rod 20 contacts the side of the inclined block 11, and the second sliding rod 20 pushes the inclined block 11 after being subjected to force, so that the staff can operate the inclined block 11 to move into the mounting groove 13 after being subjected to force, thereby further facilitating the disassembly operation between the mounting tube 4 and the mounting rod 3.

[0022] One end of two adjacent second sliding rods 20 are both installed with the first connecting rod 7 by screws, and the surface of the second sliding rod 20 is movably sleeved with a second compression spring 19, and the two ends of the second compression spring 19 are respectively connected to the end of the fixed tube 10 and the side of the first connecting rod 7 by screws. When the first connecting rod 7 is pressed, the length of the second compression spring 19 shrinks after being subjected to force. When the force on the first connecting rod 7 is cancelled, the second compression spring 19 pushes the first connecting rod 7 in the opposite direction by its own force. At this time, the position of the first connecting rod 7 is reset, which is convenient for the staff to operate next time.

[0023] A plurality of second connecting rods 8 are installed between the sides of the two first connecting rods 7 by screws. The two first connecting rods 7 and the second connecting rods 8 are arranged to connect the four second sliding rods 20 together. By applying force to the first connecting rod 7, the first connecting rod 7 pushes another first connecting rod 7 through the second connecting rod 8, and the two ends of the two first connecting rods 7 respectively apply external force to the four second sliding rods 20, which makes it convenient for the four second sliding rods 20 to apply external force to the four inclined blocks 11 at the same time, thereby improving the convenience of operation for the staff.

[0024] A base 5 is installed at the bottom end of the mounting tube 4 by means of screws. A plurality of first mounting holes 6 are provided on the surface of the base 5. When connecting the mounting tube 4 and the housing of the communication electronic device, it is only necessary to insert the screws into the first mounting holes 6 and the screw holes reserved in advance in the housing of the communication electronic device, so as to install the base in the communication electronic device, thereby improving the indoor stability of the mounting tube 4 installed in the communication electronic device.
