In the initial state, the fixed block 12 abuts against the wall of the slide groove 16 on the side away from the hinge groove 401, and the driving block 141 projects out of the driving groove 17. The driving block 141 is a hemispherical structure, the arc convex surface side of the driving block 141 faces the direction of the second mounting post 502, when the first mounting post 501 and the second mounting post 502 are gradually turned over to the horizontal state, the driving block 141 slides on the end face of the second mounting post 502 close to the first mounting post 501, so that the driving block 141 gradually slides into the driving groove 17, the driving strip 142 drives the fixing block 12 to move towards the direction far away from the second mounting post 502, and the driving fixing ring 11 is driven to move so that the ring body of the fixing ring 11 enters the fixing hook 13.

Referring to fig. 6 and 7, the first mounting post 501 is provided with a fixing member, when the first mounting post 501 and the second mounting post 502 are in a horizontal state, the driving block 141 slides into the driving groove 17, and at this time, the fixing member fixes the driving strip 142, which is beneficial to maintaining a state that a ring body of one side of the fixing ring 11, which is far away from the hinge groove 401, is located in the fixing hook 13.

Referring to fig. 6 and 7, the fixing element is a latch 20, the latch 20 is fixed on a groove wall of the driving groove 17 on a side close to the hinge groove 401, and a slot 21 is formed on a side of the driving bar 142 away from the driving block 141. When the first mounting post 501 and the second mounting post 502 are in a horizontal state, the latch 20 is clamped in the slot 21, and at this time, the latch 20 and the slot wall of the slot 21 are in a fixed state under the action of friction force.

Referring to fig. 4 and 5, the connecting rope 7 is composed of a first rope 701 and a second rope 702, and the second rope 702 is two and is disposed on two sides of the first rope 701. The end parts of the first rope body 701 and the second rope body 702 are fixedly connected with hanging rings respectively, the first rope body 701 and the second rope body 702 are fixedly connected through the hanging rings, the second rope body 702 and the mounting column 5 are fixedly connected through the hanging rings, the diameter of each hanging ring is larger than that of the corresponding connecting ring 6, after the connecting rope 7 is installed, the hanging rings are located below the corresponding connecting rings 6, the first rope body 701 is connected with the linkage rope 25, at the moment, the connecting rope 7 and the linkage rope 25 move to the position where the first mounting column 501 and the second mounting column 502 are in a horizontal state, and the hanging rings of the first rope body 701 are in contact with the corresponding connecting rings 6. The first rope body 701 is close to the hanging ring, a small breaking opening 24 is cut, when the first rope body 701 is tightened, all the first rope bodies 701 start to break under the action of the breaking opening 24, then the elastic force of the torsion spring 30 is released, the first mounting column 501 and the second mounting column 502 are turned downwards under the action of the gravity of the mounting columns 5, at the moment, the fixing ring 11 is separated from the fixing groove, the protection net 9 is spread out, secondary protection is formed, and buffering is further performed.

Referring to fig. 6 and 7, a tension spring 23 is fixedly connected to a side of the slider 8 close to the hinge slot 401, and an end of the tension spring 23 away from the slider 8 is fixed to a slot wall of the hinge slot 401 facing the other mounting seat 4. When the protective net is used, the elasticity of the tension spring 23 is released, and the slide block 8 is pulled towards the direction of the hinge groove 401, so that the protective net 9 can be kept in a tight state when the protective net 9 is unfolded, and the possibility that the fixing ring 11 is separated from the fixing hook 13 is reduced.

Referring to fig. 3 and 4, in order to facilitate recycling, connecting seats 26 corresponding to the mounting seats 4 one to one are fixedly connected to the inside of the well body 1 through bolts, a mounting groove 28 having a "T" -shaped structure is formed in the top of the connecting seat 26, and a mounting strip 27 having a "T" -shaped structure is fixedly connected to one side of the mounting seat 4 facing the connecting seat 26. When the mounting structure is mounted, the mounting strip 27 is firstly slid into the mounting groove 28 from top to bottom to mount the mounting seat 4, and when the mounting structure is dismounted, the mounting strip 27 is slid upwards to dismount the mounting seat 4. Connecting columns 29 are fixedly connected between the two mounting seats 4, and two connecting columns 29 are respectively arranged at the edge positions of the two side walls of the mounting seats 4 close to the vertical direction. The connecting column 29 comprises an inner column 291 and a column sleeve 292, the column sleeve 292 is slidably sleeved on the outer peripheral side of the inner column 291, and the opposite ends of the inner column 291 and the column sleeve 292 are respectively fixed with the mounting seats 4 to realize linkage of the two mounting seats 4. When mount pad 4 is dismantled, upwards with mounting bar 27 roll-off mounting groove 28 earlier, make inner column 291 slide in column jacket 292 in succession, reduce the interval between two mount pads 4, then take out two mount pads 4 from air outlet 3 can.

The implementation principle of ventilation shaft structure is built in room of this application embodiment is:

constitute the net rope structure with linkage rope 25 through connecting rope 7 earlier when weighing into air supply duct 2 from air outlet 3 and cushion, connect rope 7 pulling first erection column 501 and second erection column 502 to the horizontality during the buffering, slide into drive groove 17 through drive block 141 simultaneously and drive fixed block 12 and move for solid fixed ring 11 is connected with fixed hook 13. When the first rope 701 breaks, the torsion spring 30 drives the mounting column 5 to turn downwards, so that the protective net 9 is spread out, secondary buffering is facilitated, and the possibility of hidden installation troubles is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
