Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "sleeved/connected", "connected", and the like are to be understood in a broad sense, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1:
please refer to fig. 1-3, a filter device for a coal mine ventilation pipeline, comprising a ventilation pipeline 1, a first limiting groove 101 and an annular placing groove 102 are integrally formed at the inner end of the ventilation pipeline 1, the first limiting groove 101 is located at the right upper side of the annular placing groove 102, a dustproof filter screen 2 is slidably connected in the ventilation pipeline 1, the dustproof filter screen 2 is located between the first limiting groove 101 and the annular placing groove 102, a pair of semicircular notches are drilled at the left end and the right end of the first limiting groove 101, a pair of limiting blocks 201 matched with the dustproof filter screen 2 are fixedly connected at the left end and the right end of the dustproof filter screen 2, the limiting blocks 201 are semicircular limiting blocks, and a pair of rotating handles 202 are fixedly connected at the upper end of the dustproof filter screen 2.
Please refer to fig. 2-3, the lower end of the limiting block 201 is chiseled with a pair of spherical grooves, the spherical grooves are connected with the balls 3 in a sliding manner, and the balls 3 are connected with the annular placing groove 102 in a sliding manner, so that the friction force between the balls 3 and the annular placing groove 102 is reduced, the outer end of the rotating handle 202 is sleeved with a rubber sleeve, the outer end of the rubber sleeve is carved with anti-slip lines, so that the friction force between the rotating handle 202 and the palm of the worker is increased, and the worker can save more labor when the worker installs and detaches the dustproof filter screen 2 by setting the balls 3 and the rubber sleeve with the anti-slip lines to rotate the rotating handle 202 to adjust the position of the limiting block 201.
