Detailed Description

As shown in fig. 1-4, a lock body waterproof and dustproof cover includes a housing 1, a sliding cover 2 and a fixing cover 3 installed outside the lock body, it should be noted that the housing 1 is not affected by the present embodiment, and it may be a plate processed from the existing lock surface or a plate processed after it, specifically depending on the actual production needs. Be equipped with mounting groove 4 on the casing 1, slide lid 2 assembles in mounting groove 4 with fixed lid 3 in proper order, fixed mounting between fixed lid 3 and the mounting groove 4, fixed lid 3 bottom is equipped with sliding tray 5, slide lid 2 is at linear reciprocating motion in sliding tray 5. The sliding cover 2 is arranged between the fixed cover 3 and the shell 1 to slide, and meanwhile, the positioning is realized through elastic clamping, so that a certain state is kept. The plane of the notch of the fixed cover 3 and the mounting groove 4 is flush, and is different from some projected product designs on the market, so that the fixed cover 3 is not easy to fall out and is not easy to be damaged by external collision.

Fixed 3 tops of lid are equipped with the open fluting 6 of fretwork, be equipped with the butt piece 7 that stretches out from fluting 6 on the lid that slides 2, and slide 2 and be equipped with elasticity stuck point 8 on relative both sides wall, be equipped with on the relative lateral wall of sliding tray 5 with elasticity stuck point 8 complex draw-in groove 9.

The bottom of the fixed cover 3 is provided with elastic clamping columns 10 with symmetrical positions, the center of each elastic clamping column 10 is provided with a through groove 11 which runs through, the outer wall of each elastic clamping column 10 is provided with a reinforcing rib ring 12, and the shell 1 is provided with a slot 13 for inserting the elastic clamping column 10. The elastic clamping column 10 is through in the middle, so that elastic deformation within a certain limit can occur during plugging. The design of the reinforcing rib ring 12 can on the one hand reinforce the local structural strength and on the other hand make the mounted structure more stable.

The abutting block 7 is provided with a plurality of anti-skid protrusions 14 which are arranged in a matrix mode, the anti-skid protrusions 14 can enhance anti-skid performance, and a user can conveniently push the opening and closing.

The outer edge of one end of the sliding cover 2 close to the abutting block 7 is provided with a limiting cutting groove 15, the end of the sliding cover 2 opposite to the abutting block 7 is provided with an elastic clamping strip 16, and the elastic clamping point 8 is arranged on the elastic clamping point 8. The design of the limiting slot 15 provides space for the elastic clamping column 10, and can also improve the travel distance and optimize the spatial layout as much as possible. A trapezoid-shaped groove 17 is formed between the sliding cover 2 and the elastic clamping strip 16, and the width of the elastic clamping strip 16 is gradually increased from one end of the elastic clamping point 8 to the other end of the elastic clamping point. The elastic clamping strip 16 is designed to be clamped and positioned at the elastic clamping point 8, and meanwhile, the width of the connecting part is large due to the diameter change, the rigidity is strong, the long-term use is facilitated, and the service life is prolonged.

The sliding cover 2 is provided with a hollow groove 18 at the position corresponding to the abutting block 7 at the bottom, so that unnecessary local solidifications are avoided, the weight and the cost are reduced, and convenience is brought to a user to push.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
