[0037] Please refer to Figures 1 to 5 The embodiment provides a kind of blocking pin plate device, installs in the side wall of structural member 100 and is located at the end of pin shaft mounting hole 110, for limiting the axial movement of hinged pin 120 inserted into pin shaft mounting hole 110, including: blocking pin 400 plate assembly, baffle 300 and blocking pin 400;Blocking pin 400 plate assembly is fixedly installed in the side wall of structural member 100, and the clamping channel is formed between blocking pin 400 plate assembly and the side wall of structural member 100;Baffle 300 is inserted in clamping channel, and baffle 300 is used to prevent hinged pin 120 from outward axial movement;Blocking pin 400 is located in blocking pin 400 plate assembly, for preventing baffle 300 from disengaging from clamping channel.

[0038] Specifically, blocking pin 400 plate assembly is installed on the side wall of structural member 100 at the both ends of pin shaft mounting hole 110, and a clamping channel can be formed between it and the side wall, and baffle 300 can be directly inserted into the inside of clamping channel, so that the outward movement of hinged pin 120 can be prevented by baffle 300, and in order to prevent baffle 300 from disengaging from clamping channel, blocking pin 400 is also installed on blocking pin 400 plate assembly;In the embodiment, the installation position of blocking pin 400 plate assembly can be adjusted according to different pin shaft mounting hole 110 aperture, and different length baffle 300 is selected, so that the axial limiting of hinged pin 120 with different diameters can be realized.

[0039] As preferred, blocking pin 400 plate assembly includes first blocking pin plate 210 and second blocking pin plate 220, and the installation positions of first blocking pin plate 210 and second blocking pin plate 220 are symmetrical about the axis of pin shaft mounting hole 110, first blocking pin plate 210 and second blocking pin plate 220 are both provided with recess 230, and recess 230 is attached to the side wall of structural member 100 to form clamping channel.

[0040] In the embodiment, the blocking pin 400 plate assembly comprises a first blocking pin plate 210 and a second blocking pin plate 220 arranged oppositely, both of which are arranged at two sides of the pin shaft mounting hole 110 and the line connecting the centers of the two plates passes through the axis of the pin shaft mounting hole 110. In this way, the clamping channel formed by the side wall and the blocking plate 300 can pass through the center of the hinge pin 120, thereby ensuring the blocking effect of the blocking plate 300 on the hinge pin 120.

[0041] In the embodiment, the clamping channel is mainly composed of the groove 230 and the side wall of the structural member 100. Specifically, as shown in Figure 2 and Figure 3 , the groove 230 is arranged on the inner side of the first blocking pin plate 210 and the second blocking pin plate 220, i.e., the side close to the structural member 100. When the first blocking pin plate 210 and the second blocking pin plate 220 are installed, the groove 230 will form a clamping channel together with the side wall of the structural member 100. It should be noted that the groove 230 arranged on the inner side of the first blocking pin plate 210 and the second blocking pin plate 220 has the same structure and shape. Since the straight line connecting the first blocking pin plate 210 and the second blocking pin plate 220 passes through the center of the circle, the clamping channel formed by the first blocking pin plate 210 and the second blocking pin plate 220 is also on a straight line, which facilitates the insertion of the blocking plate 300. In this way, the blocking plate 300 inserted into the clamping channel can limit the axial movement of the hinge pin 120 installed in the pin shaft mounting hole 110, preventing the hinge pin 120 from moving outward. In addition, when it is necessary to install the end of the pin shaft mounting hole 110 with different hole diameters, only the blocking plate 300 with different lengths needs to be replaced, which greatly increases the versatility of the blocking pin 400 plate device and can adapt to more hinge pins 120.
