DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4, a photoelectric coupler detector, comprising a workbench 1, a fixing mechanism 2 is equidistantly arranged on the top of the workbench 1, the fixing mechanism 2 comprises a fixing plate 21, a pressing plate 22, a mounting seat 23, a clamping block 24, a supporting seat 25, a fixing block 26, a limiting plate 27, a limiting spring 271, a mounting fixing block 28, and a fixing shaft 281;

[0022] Among them, a fixed shaft 281 is installed at the lower part of the headquarters between the two supporting seats 25, and a mounting block 28 is rotatably installed on the outer wall of the fixed shaft 281. A fixed plate 21 is installed in the middle of the top of the mounting block 28, and fixed blocks 26 are symmetrically installed on both sides of the fixed plate 21. A sliding groove is opened on the top of the fixed block 26, and a limiting spring 271 is installed in the middle of the bottom of the sliding groove, and the top of the limiting spring 271 is connected to the limiting plate 27. A limiting slider 221 is slidably installed in the sliding groove, and one end of the limiting slider 221 passes through the fixed block 26 and is connected to the pressure plate 22, and sliders 222 are installed on the front and rear sides of the limiting slider 221, and a fastening threaded rod 223 is installed vertically downward in the middle of the bottom of the slider 222, and a fastening nut is installed on the outer wall of the fastening threaded rod 223.

[0023] At the same time, a limiting sliding groove is provided at the top of the fixing block 26 at the corresponding sliding block 222 , and through holes are provided at the fixing block 26 and the limiting plate 27 at the corresponding fastening threaded rod 223 .

[0024] In addition, a protective pad layer is installed on the bottom of the pressing plate 22 and the top of the fixing plate 21. The protective pad layer is made of a flexible material, so that the protective pad layer plays a flexible protective role on the photoelectric coupler.

[0025] Among them, a mounting seat 23 is installed in the middle of one side of the top support seat 25 of the fixed block 26, and a limiting groove is opened in the middle of the mounting seat 23, a rotating shaft is installed in the middle of the limiting groove, and a clamping block 24 is installed on the mounting seat 23 through the rotating shaft, and the clamping block 24 is L-shaped.

[0026] At the same time, a clamping groove is formed on the top of the support seat 25 at the corresponding clamping block 24 .

[0027] In addition, a through hole is formed in the mounting and fixing block 28 at a position corresponding to the fixing shaft 281 .

[0028] In this embodiment, the photoelectric coupler is placed on the top of the fixed plate 21, and then the pressure plate 22 drives the corresponding fastening threaded rod 223 to pass through the corresponding through holes of the fixed block 26 and the limiting plate 27 in sequence, and is tightened and fixed with a fastening nut, thereby realizing the limiting fixation of multiple photoelectric couplers through the fixing mechanism 2.

[0029] During the movement of the pressure plate 22, the protective pad layer at the bottom of the pressure plate 22 and the top of the fixed plate 21 provides flexible protection for the photoelectric coupler, and the limit slider 221 of the pressure plate 22 presses against the corresponding limit plate 27, and the limit spring 271 at the bottom of the limit plate 27 supports the pressure plate 22.

[0030] After the photoelectric coupler is limited and fixed, the locking block 24 is rotated and moved away from the locking groove of the support seat 25, and then the photoelectric coupler is rotated around the fixed axis on the basis of the installation fixing block 28 by holding the fixing block 26, so as to facilitate the user to carefully check the pins of the photoelectric coupler from multiple angles.

[0031] When there is no need to rotate the photoelectric coupler, the fixing block 26 of the fixing mechanism 2 is rotated close to the clamping block 24 to be flush with the clamping groove of the support seat 25, and the clamping block 24 is quickly rotated and clamped into the clamping groove of the support seat 25, thereby completing the limiting fixation of the photoelectric coupler.

[0032] In the utility model, the fixing mechanism 2 is used to limit and fix multiple photoelectric couplers, so that the user can detect and compare the pins of multiple photoelectric couplers. At the same time, the fixing block 28 is installed and rotated around the fixed axis, so that the user can carefully check the pins of the photoelectric couplers from multiple angles.
