[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0025] Example

[0026] See also Figure 1 to Figure 6 In this embodiment, a dust-proof net for coal mine environmental protection that is easy to install is provided, including a fixed frame 1, and a slide groove 11 is provided on both the left and right side walls of the fixed frame 1. A plurality of dust-proof frames 2 are installed in the slide groove 11, and the dust-proof frames 2 are plugged and fixedly combined with each other in the vertical direction thereof, thereby forming a required protection area for achieving dust prevention, and the dust-proof frame 2 at the bottom is plugged with the bottom of the fixed frame 1 to increase its stability after installation;

[0027] The dustproof frame 2 includes an outer frame 21, and a protective net 24 is installed inside the outer frame 21. The protective net 24 has a dustproof effect. Among them, the upper surface of the outer frame 21 is provided with two left-right symmetrical slots 22, and the lower surface of the outer frame 21 is provided with plug rods 23 corresponding to the two slots 22. The plug rods 23 are adapted to the slots 22. When the dustproof frame 2 is vertically placed in the slide groove 11, the plug rod 23 at the bottom of the upper dustproof frame 2 will be inserted into the slot 22 on the upper surface of the lower dustproof frame 2, so as to achieve the plug-in fixation between the two. In addition, a limiting mechanism 25 is also provided in the outer frame 21. The limiting mechanism 25 can realize the limit fixation of the plug rod 23 inserted into the slot 22 to prevent the two dustproof frames 2 plugged into each other from being separated. At the same time, it can also facilitate the separation of the two dustproof frames 2 plugged into each other. The limiting mechanism 25 can be adjusted. On the one hand, it can realize the limit fixation of the plug rod 23, and on the other hand, it can also be separated from the plug rod 23, which is conducive to separating the two dustproof frames 2, thereby facilitating the replacement of the dustproof frames 2.

[0028] It should be noted that the inner bottom of the fixed frame 1 is provided with two bottom grooves 12. The dustproof frame 2 is first placed in the slide groove 11, and the insertion rod 23 at the bottom thereof is located in the bottom groove 12;

[0029] The limiting mechanism 25 includes a central groove 251, which is located at the center between the two slots 22. A sliding hole 252 is provided between the central groove 251 and the slot 22. A limiting rod 253 is slidably connected in the sliding hole 252. The upper surface of the limiting rod 253 close to the slot 22 is provided with a smooth inclined surface inclined downward, and the other end is sleeved with a limiting ring 254. The limiting rod 253 is slidably connected in the limiting ring 254, and the outer side wall of the limiting ring 254 is fixed to the inner wall of the sliding hole 252. In addition, a spring 255 is sleeved on the limiting rod 253, one end of the spring 255 is fixed to the limiting rod 253, and the other end is connected to the limiting ring 254, so that the spring 255 can have a squeezing effect on the limiting rod 253, driving it to move to one side of the slot 22;

[0030] A winding wheel 256 is installed in the central groove 251, and the winding wheel 256 is rotatably connected to the side wall of the central groove 251. At the same time, a handle 257 is installed on the front side of the winding wheel 256. The end of the handle 257 passes through the front side wall of the central groove 251 and is located outside the central groove 251, so that the external user can adjust it. The winding wheel 256 is connected to the limit rods 253 on the left and right sides through a pull rope 258.

[0031] The user holds the handle 257 and rotates it, which then drives the winding wheel 256 to rotate, thereby winding the pull rope 258. After the pull rope 258 is pulled and wound, it gradually shortens in the early stage, and then pulls the two limit rods 253 to approach each other and move to the side of the central groove 251, and compresses the spring 255. At this time, the two limit rods 253 will be separated from the plug rod 23, so that the plug rod 23 can be separated from the slot 22, that is, the two dustproof frames 2 that are plugged and fixed to each other are separated, which is convenient for their maintenance and replacement;

[0032] On the contrary, after the grip 257 is released, the limiting rods 253 are moved away from each other again under the action of the spring 255, and the ends thereof are placed in the slot 22. If the insertion rod 23 is in the slot 22 at this time, it is limited and fixed again;

[0033] When the two dustproof frames 2 are not plugged in at the beginning, there is only the end of the limit rod 253 in the slot 22. At this time, the dustproof frame 2 slides down from the slide slot 11, and relying on the action of gravity, the insertion rod 23 will enter the slot 22. At this time, the upwardly inclined smooth inclined surface set at the bottom of the insertion rod 23 interacts with the inclined surface on the limit rod 253, relying on gravity, the limit rod 253 can be squeezed and the spring 255 can be compressed at the same time. Under the action of gravity, the insertion rod 23 is completely inserted into the slot 22. Since a limit hole 26 is set on the side of the insertion rod 23 close to the limit rod 253, the limit rod 253 moves away from each other again under the action of the spring 255, and its end is inserted into the limit hole 26 to realize the limit fixation of the insertion rod 23 and complete the installation between the two dustproof frames 2. Conversely, rotating the handle 257 can disengage the limit rod 253 from the insertion rod 23 to realize the disassembly between the two.

[0034] The utility model provides a limit mechanism 25 inside the outer frame 21 of the coal mine environmental protection dustproof net. The limit mechanism 25 can limit and fix the two dustproof frames 2 when they are installed and facilitate disassembly. During installation, the upper dustproof frame 2 can be plugged in and fixed by its own gravity. Conversely, adjusting the limit mechanism 25 can realize the separation and disassembly of the installed dustproof frames 2, which is beneficial to the inspection, replacement and reuse of the dustproof frames 2.

[0035] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. Structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to conventional means in the field unless otherwise specified and limited.
