Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments to assist understanding of the invention. The method used in the utility model is a conventional method if no special regulation is provided; the raw materials and the apparatus used are, unless otherwise specified, conventional commercially available products.
Shown by fig. 1-5, the utility model provides a guardrail is used in protection of fan vent, it includes linking bridge 1 and the breast body 2, linking bridge 1 is equipped with two, respectively with 4 fixed connection of wall body of fan vent both sides, the both ends of breast body 2 can be dismantled with two linking bridge 1 respectively and be connected. Connecting bracket 1 still is equipped with the fence body dropout prevention means, avoids fence body 2 and connecting bracket 1 separation accident to drop, does not play the guard action.
Furthermore, the connecting support 1 is provided with an L-shaped pin shaft 11, the connecting end of the L-shaped pin shaft 11 is vertically upward, pin shaft connecting holes 21 are formed in two ends of the rail body 2, and the pin shaft connecting holes 21 are sleeved on the outer circumference of the pin shaft 11, so that the rail body 2 is hung on the outer side of the connecting support 1 and is detachably connected with the connecting support 1.
The fence body anti-falling device comprises a connecting plate 3 and a pressing plate 32, wherein the connecting plate 3 is fixedly connected with the connecting support 1, and the extending direction of the connecting plate 3 is perpendicular to the extending direction of the connecting support 1. The pressing plate 32 is L-shaped, one end of the L-shaped is rotatably connected with the connecting plate 3 through a screw, the other end of the L-shaped extends along the horizontal direction and is arranged above the pin shaft connecting hole 21, the pin shaft connecting hole 21 is blocked to prevent the pin shaft connecting hole 21 from being separated from the pin shaft 11, so that the rail body 2 is fixedly connected with the connecting support 1, and the rail body 2 is effectively prevented from falling off from the connecting support 1.
