Detailed Description
The utility model will be further described with reference to the accompanying drawings in which: as shown in the figure, the dustproof assembly of the lockset comprises an installation piece 1, wherein a through groove 11 for a key to pass through is arranged on the installation piece; at least two dust-proof plates 2, at least one of which is movably matched with the mounting piece, wherein each dust-proof plate comprises a first position for covering the through groove and a second position for exposing the through groove after a key is inserted; and the elastic piece 3 is used for driving the dust guard to be in the first position, and the elastic piece is arranged on the mounting piece or the dust guard. As one of the alternatives, the mounting member may be a plate-shaped structure, the through groove is used for a key to pass through, the dust guard is used for preventing a foreign matter from entering the lock cylinder, the through groove is covered by the elastic force of the elastic member in a normal state, when the key is inserted, the dust guard is squeezed open to expose the through groove for key matching, the two dust guards can move together or move in a single side, and the scheme can be realized. The dust guard is preferably a sliding fit with the mounting.
In the utility model, as shown in the figure, the elastic piece is installed by clamping two dust-proof plates. As the preferred scheme, the elastic piece realizes the furling of the dust guard on the one hand through the elasticity of the elastic piece, and also realizes the stable installation of the elastic piece on the other hand, so that the structure is more compact, no additional part is needed, and the cost is lower.
In the utility model, as shown in the figure, the elastic part comprises two pins 31 with elastic force which are close to each other, the outer side of the dustproof plate is provided with a mounting groove 21, and the pins extend into the mounting groove and are in abutting fit with the inner wall of the mounting groove.
