Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] like Figure 1 The safety interlocking guardrail for the wire drawing equipment shown includes a column body 1 and a column head 2, wherein the column head 2 is placed on top of the column body 1 via a first rotating shaft 3.

[0016] The column head 2 is connected to a railing connecting seat 5 via a second rotating shaft 4. The railing connecting seat 5 is fixed with a railing body 6. The second rotating shaft 4 enables the railing body 6 to switch from a horizontal position to a vertical position. A first trigger switch 7 is provided inside the column head 2 to sense the position of the railing body 6.

[0017] The first rotating shaft 3 extends into the column body 1 and is fixed with a fixing block. The railing body 6 rotates horizontally to drive the fixing block to rotate. The column body 1 is provided with a second trigger switch 8 that senses the angle position of the fixing block.

[0018] The first trigger switch 7 and the second trigger switch 8 are both connected to and control the wire drawing equipment. When the main body of the railing 6 is raised or rotated, the equipment stops.

[0019] The first trigger switch 7 and the second trigger switch 8 are both position switches, which are triggered by the position changes of the railing connecting seat 5 and the fixing block, respectively. The railing connecting seat 5 and the fixing block are both irregularly shaped parts, which can generate local displacement by rotation, thereby triggering the position switches.

[0020] The push plate 9 extends downward from one side of the column head 2 and rotates with the column head 2. The column body 1 is provided with a limiting plate 10 on the rotating path of the push plate 8. The push plate 9 and the limiting plate 10 are connected by a first spring 11 to keep the rotating pre-tightening force of the railing body 6. When a person leans against the railing to a certain angle, the second trigger switch is triggered.

[0021] The column head 2 is provided with a spring lock corresponding to one side of the railing connecting seat 5. After the railing body 6 is lifted, the spring lock limits the railing connecting seat 5.

[0022] The spring lock includes a fixed frame 12. A pull ring plug 13 is inserted from one side of the fixed frame 12 and extends through the other side to the railing connecting seat 5. The part of the pull ring plug 13 in the fixed frame 12 is fixed with a limiting block. The limiting block and the fixed frame 12 on one side of the pull ring are provided with a second spring 14 to provide the pull ring plug 13 with a spring force to move to the railing connecting seat 5. The spring lock is unlocked by pulling the pull ring.

[0023] The railing connecting seat 5 is provided with a limiting groove. When the railing body 6 is lifted to the vertical position, the spring lock automatically limits the limiting groove by the plug under the action of the spring force.
