Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, the present invention discloses an embedded type suspension cage door, which includes a door frame 10, a door body 20 and a counterweight structure 30, wherein the counterweight structure 30 includes a counterweight 31, a steel rope 32 and a fixed pulley 33, the fixed pulley 33 is installed at the top of the door frame 10, the steel rope 32 bypasses the fixed pulley 33, one end of the steel rope 32 is connected to the counterweight 31, and the other end is connected to the bottom of the door body 20; the counterweight block 31 of the counterweight structure 30 realizes the effect of mutual offsetting with the gravity of the door body 20 through the effect of the fixed pulley 33, is beneficial to the opening and closing of the door body 20, and can ensure that the door body 20 is kept in an opening state when the door body 20 is opened;
