The invention discloses a needle device for a safety syringe, comprising a needle cap and a thin needle tube. A plurality of sets of ratchets are distributed around the top side wall of the thin needle tube, and each set of ratchets includes at least two sets of pawls along the length of the thin needle tube. The ratchet claws are distributed in the directions. There are a plurality of ratchet claws corresponding to each group of ratchet claws around the inner wall of the inner hole of the needle cap. The ratchet block is clamped, and the outer wall of the top end of the thin tube of the needle is sealed with a sealing ring, and the outer circumferential wall of the sealing ring is sealed with the inner wall of the inner hole of the needle cap. The needle cap is truly separated and the needle can be recycled separately.

The invention relates to an air conditioner draught fan box which comprises a frame and foaming panels. The frame comprises three-way pieces, frame strips, edge frame pressing plate strips and liner pressing plate strips. The corresponding frame strips are inserted in the three ways of each three-way piece respectively in a matched mode, the liner pressing plate strips are connected to the frame corners, facing the inner side of the box, of the frame strips in the length direction of the frame strips in a sliding mode, and the foaming panels are fixed and clamped by the liner pressing plate strips and the edge frame pressing plate strips. Protruding limiting ribs and protruding screw seats are arranged on the sides, used for clamping the foaming panels, of the edge frame pressing plate strips, limiting grooves matched with the protruding limiting ribs are formed in the outer side frame faces of the frame strips, the liner pressing plate strips and the protruding screw seats of the edge frame pressing plate strips are fixedly connected through self-drilling and self-tapping screws with pads in the direction towards the edge frame pressing plate strips from the liner pressing plate strips, and the self-drilling and self-tapping screws with the pads do not penetrate through the edge frame pressing plate strips after being fastened to the protruding screw seats. The air conditioner draught fan box is reliable in structural connection, the screw pieces are not exposed, integral attractiveness is achieved, the sealing performance and the cold-bridge prevention effect are good, and the air conditioner draught fan box is suitable for serving as boxes of various air conditioner draught fans.

The invention belongs to the technical field of LED lighting, and discloses an LED lamp housing and a sealing method thereof. The LED lamp housing includes an upper cover, and the edge of the cover of the upper cover is provided with a protruding card edge, and the card The first sawtooth groove is evenly arranged on the side; and the lower cover body, the edge of the cover shell of the lower cover body is provided with a card slot, the card slot has an inner card slot edge and an outer card groove edge, and the inner card groove edge Second sawtooth grooves are evenly arranged on the top and alternately distributed with the first sawtooth grooves; the card edge can be inserted into the card slot. The present invention sets the first sawtooth groove and the second sawtooth groove which are interlaced with each other. When pouring glue, the intersected intersecting grooves can eliminate the air bubbles in the gap, avoiding the generation of air bubbles during bonding, even if they appear It can also decompose large bubbles into small bubbles through the sawtooth structure, avoiding large bubbles in the bonding seam, thereby ensuring the sealing performance, making the structural connection more firm and reliable, and further ensuring the waterproof effect.
