Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be 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 present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a double-layer protective net structure, including a rectangular and hollow outer frame 1 and multiple reinforcing mechanisms 7;

[0021] The inner edges of both sides of the outer frame 1 are tapered inward to form recessed grooves 2. The front guard net 3 and the rear guard net 4 are detachably installed inside the recessed grooves 2 on both sides of the outer frame 1. Multiple reinforcement mechanisms 7 are arranged between the front guard net 3 and the rear guard net 4.

[0022] All the reinforcement mechanisms 7 have the same structure. One of the reinforcement mechanisms 7 includes a first fixing block 71 fixedly connected to the front guard net 3. A sliding hole 72 is opened through the front surface of the first fixing block 71. A movable sleeve 74 with a closed rear end is slidably connected to the inside of the sliding hole 72. A second fixing block 76 corresponding to the first fixing block 71 is fixedly connected to the rear guard net 4. A threaded hole 77 is opened through the rear surface of the second fixing block 76. A through hole 79 corresponding to the threaded hole 77 is opened through the rear surface of the movable sleeve 74.

[0023] In this embodiment, after the front protective net 3 and the rear protective net 4 are installed on the main frame 1, a screwdriver can be used to insert a screw into the front opening of the first fixing block 71 in the reinforcing mechanism 7 and push it backward. During this process, the movable sleeve 74 will move to the front end of the second fixing block 76. At this time, turning the screwdriver will cause the screw to rotate. Under the action of the threaded hole 77 of the second fixing block 76, the screw will be screwed into its interior, which can connect the movable sleeve 74 and the second fixing block 76. In this way, the front protective net 3 and the rear protective net 4 can be connected. The two support each other, which can further improve the stability of the two after installation, thus greatly improving the protective ability of the protective net.

[0024] In its initial state, the movable sleeve 74 is located inside the first fixing block 71. At this time, after the front guard net 3 and the rear guard net 4 are installed, there will be no contact between the first fixing block 71 and the second fixing block 76, and the installation of the front guard net 3 and the rear guard net 4 will not be affected.

[0025] Furthermore, the front end of the sliding hole 72 is expanded outward to form a limiting groove 73, and a limiting ring 75 with an outer diameter that matches the inner diameter of the limiting groove 73 is fixedly connected to the front end of the outer surface of the movable sleeve 74.

[0026] In this embodiment, the limiting ring 75 serves as a limiting element, preventing the movable sleeve 74 from disengaging from the rear end of the sliding hole 72.

[0027] Furthermore, the front end of the threaded hole 77 is expanded outward to form an insertion groove 78 whose inner diameter matches the outer diameter of the movable sleeve 74.

[0028] In this embodiment, the insertion groove 78 can guide the movable sleeve 74, ensuring that the through hole 79 on it can be aligned with the threaded hole 77.

[0029] Furthermore, both sides of the outer frame 1 are fixedly connected with overlapping frame 5 that matches its contour, and the inner edges of the two overlapping frame 5 extend to the inner sides of the outer edges of the front guard net 3 and the rear guard net 4, respectively.

[0030] The inner surfaces of the two outer frames 1 are fixedly connected with fixing strips 6 that are adapted to their contours, and the fixing strips 6 on both sides are respectively attached to the outer surfaces of the front guard net 3 and the rear guard net 4.

[0031] In this embodiment, the two overlapping frame edges 5 and the fixing strips 6 thereon provide external support and fixation for the front guard net 3 and the rear guard net 4, further improving the stability of both after installation.

[0032] Furthermore, multiple mounting holes 8 are provided through the outer surface of the outer frame 1.

[0033] In this embodiment, the mounting hole 8 facilitates the installation of the device onto a window frame or other mounting location.

[0034] The working principle and usage process of this utility model are as follows: After the front protective net 3 and the rear protective net 4 are installed on the main frame 1, a screwdriver can be used to insert a screw into the front opening of the first fixing block 71 in the reinforcing mechanism 7 and push it backward. During this process, the movable sleeve 74 will move to the front end of the second fixing block 76. At this time, turning the screwdriver will cause the screw to rotate. Under the action of the threaded hole 77 of the second fixing block 76, the screw will be screwed into its interior, which can connect the movable sleeve 74 and the second fixing block 76. In this way, the front protective net 3 and the rear protective net 4 can be connected. The two support each other, which can further improve the stability of the two after installation, thus greatly improving the protective ability of the protective net.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
