[0026] Figure 1-Figure 3The utility model shows an embodiment of the construction process of the elevator shaft edge protection which avoids secondary dismantling, which comprises: a fixed frame 1, a protective net 11 is fixedly connected to the inner wall of the fixed frame 1; mounting seats 13 are fixedly connected at positions near the top and bottom ends on both sides of the fixed frame 1; auxiliary fixing mechanisms 14 are arranged at positions near the center on both sides of the fixed frame 1; a folding mechanism 12 is arranged at the bottom end of the fixed frame 1, and the folding mechanism 12 comprises a foot board 120, which is arranged at the bottom end of the fixed frame 1, and the top end of the foot board 120 is rotatably connected to the fixed frame 1 through a hinge 121, and the left and right sides of the front and rear ends of the bottom of the foot board 120 are fixedly connected with a fixing seat 122, and the interior of the fixing seat 122 is sleeved with a latch 123, one side of the latch 123 is fixedly connected to a connecting plate 124, and the other side of the latch 123 passes through a lower positioning seat 129, and the lower positioning seat 129 is fixedly connected to the fixed On both sides of the bottom end of the fixed frame 1, a first spring 126 is arranged between the connecting plate 124 and the fixing seat 122, and an upper positioning seat 130 is fixedly connected at the position near the middle of the left and right sides of the fixing frame 1; the upper and lower ends of the connecting plate 124 are fixedly connected with anti-skid pads 125, the anti-skid pads 125 are semi-cylindrical in design, and the anti-skid pads 125 are made of rubber, and the anti-skid pads 125 increase the friction force to avoid slipping due to too small friction force when the connecting plate 124 is pulled; the side of the first spring 126 close to the connecting plate 124 is fixedly connected to the connecting plate 124, and the side of the first spring 126 away from the connecting plate 124 is fixedly connected to the fixing seat 122; the upper and lower ends of the inner wall of the fixing seat 122 are fixedly connected with a first slider 127, the first slider 127 is slidably connected to the inside of the first slide groove 128, and the first slide groove 128 is arranged at the upper and lower ends of the latch 123;When the foot guard 120 is to be flipped, the connecting plate 124 is first pulled so that the connecting plate 124 drives the latch 123 to move, so that the latch 123 is disengaged from the inside of the lower positioning seat 129. At the same time, the first spring 126 fixedly connected to the connecting plate 124 is also stretched to produce elastic deformation. When the latch 123 moves, the first slider 127 fixedly connected to the inner wall of the fixing seat 122 also slides synchronously inside the first sliding groove 128. The combination of the first slider 127 and the first sliding groove 128 plays the effect of guiding and limiting the movement of the latch 123 to prevent the latch 123 from moving excessively. When the latch 123 is disengaged from the lower positioning seat 129, the fixing effect of the latch 123 on the foot guard 120 is released, and the foot guard can be flipped over. 120 makes the foot guard 120 rotate with the hinge 121 as the axis. Before the foot guard 120 turns upward to the limit, first pull the two groups of connecting plates 124 originally located in front of the foot guard 120, and then pull the two groups of connecting plates 124 originally located at the back of the foot guard 120 to move the latch 123 to prevent the latch 123 from blocking the foot guard 120, so that the lower positioning seat 129 cannot turn upward to the limit. When the foot guard 120 turns upward to the limit, loosen all the connecting plates 124. At this time, the two groups of connecting plates 124 and the latch 123 originally located behind the foot guard 120 move under the action of the restoring force of the first spring 126, so that the latch 123 is inserted into the interior of the upper positioning seat 130, which plays the effect of fixing the foot guard 120. ;

[0027] Figure 4-Figure 5The utility model shows an embodiment of the elevator shaft edge protection which can avoid secondary dismantling during the construction process. The auxiliary fixing mechanism 14 includes a connecting seat 141, which is fixedly connected to the left and right sides of the fixing frame 1 near the middle position, and the connecting seat 141 is arranged above the upper positioning seat 130. The bottom end of the connecting seat 141 is provided with an active cavity 142, and the interior of the active cavity 142 is provided with a positioning block 143, and the interior of the active cavity 142 is also provided with a second spring 144. The bottom end of the positioning block 143 is provided with a rotating cavity 147, and the rotating cavity 147 is provided with a second spring 144. A roller 148 is rotatably connected to the inner wall; the bottom end of the second spring 144 is fixedly connected to the top end of the positioning block 143, and the top end of the second spring 144 is fixedly connected to the top end of the inner wall of the active cavity 142; a second slider 145 is fixedly connected to the rear side of the positioning block 143, and the second slider 145 is slidably connected to the inside of the second slide groove 146, and the second slide groove 146 is opened on the rear side of the inner wall of the active cavity 142; when the foot guard 120 is turned upward, the foot guard 120 and the roller 148 at the bottom end of the positioning block 143 are in contact, and the roller 148 is pressed against the bottom end of the positioning block 143. The roller 148 converts the sliding friction during contact into rolling friction, thereby reducing the friction resistance between the foot guard 120 and the roller 148, so that the roller 148 can smoothly drive the positioning block 143 to move into the inside of the movable cavity 142 under the action of the squeezing force, so that the second spring 144 is squeezed and elastically deformed. When the foot guard 120 flips upward to the limit, the squeezing force of the foot guard 120 on the roller 148 and the positioning block 143 disappears. At this time, the positioning block 143 and the roller 148 are under the restoring force of the second spring 144. The second spring 144 is used to move the second slider 145 and the second slider 146 to prevent the second slider 145 from moving too far and coming out of the active cavity 142.
