Detailed Implementation
[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] The embodiments of this utility model will be described below based on its overall structure.
[0037] Example 1: A quick-assembly and disassembly safety net, such as... Figures 1-7 As shown, the system includes a safety net assembly 1 and a mounting base 2. A limiting plate 3 is connected inside the mounting base 2. A torsion spring 4 is connected between one side of the limiting plate 3 and the inner wall of one side of the mounting base 2. A first hanging rod 5 is connected to the other side of the limiting plate 3, and the first hanging rod 5 passes through the mounting base 2. One end of the first hanging rod 5 is connected to a fixing plate 6. A second hanging rod 14 is connected to the lower side of one side of the mounting base 2. An installation tube 9 is connected to the middle of one side of the mounting base 2. A spring 12 is placed inside one side of the installation tube 9. A pull rod 10 is connected to the middle of the installation tube 9 via a shoulder 11. One end of the pull rod 10 is connected to a locking block 13. The safety net assembly 1 includes a thickened periphery 101, and several hanging holes 102 are formed on the outer surface of the thickened periphery 101. When installing the safety net, the worker first inserts the hanging holes 102... Hang the first hanging rod 5 on the second hanging rod 14, and then hang the first hanging rod 5 on the steel pipe, so that the steel pipe is between the first hanging rod 5 and the installation pipe 9. At this time, rotate the fixing plate 6 to make it contact the second hanging rod 14. The first hanging rod 5 drives the limiting plate 3 to rotate, causing the torsion spring 4 to rotate. When the fixing plate 6 contacts the locking block 13, the locking block 13 is squeezed and drives the pull rod 10 to move and retract into the installation pipe 9. At the same time, under the action of the pull rod 10, the shoulder 11 cooperates with the inner wall of the installation pipe 9 to compress the spring 12. When the locking groove 7 corresponds to the locking block 13, under the action of the spring 12, the locking block 13 enters the locking groove 7 to limit and fix the fixing plate 6. Repeat the above operation until all the hanging holes 102 are installed, thereby completing the installation of the safety net.
[0038] See Figures 1-7In the above embodiment, the pull rod 10 penetrates the mounting pipe 9 and the mounting base 2 respectively, and the pull rod 10 is in sliding connection with the mounting base 2. When the safety net is installed or disassembled, the worker only needs to rotate the fixed plate 6 or release the pull rod 10, so that the spring 12 is retracted or restored to the original position. Under the action of the elastic force of the spring 12, the pull rod 10 drives the clamping block 13 to move, so that the clamping block 13 leaves or enters the clamping groove 7, thereby opening or locking the device, and the operation method is simple and fast.
