The present application relates to the technical field of furniture, and discloses a drawer, which comprises a drawer body and a slide rail assembly, the drawer body is connected with an upper rail of the slide rail assembly through a first limiting piece, a second limiting piece and a lock catch, when the lock catch is rotated to below the upper rail, the drawer body and the upper rail are locked by the lock catch and cannot be separated, when the lock catch is rotated to not below the upper rail, the drawer body and the upper rail are not locked by the lock catch and can be separated. Based on the above structure, the connection between the drawer body and the slide rail assembly is not only firm, safe and reliable, but also convenient to disassemble and assemble, which is beneficial to production and maintenance. In addition, the present application also discloses a cabinet, since the cabinet adopts the above-mentioned drawer, the cabinet has the advantages of convenient production and maintenance, large storage capacity, small noise and good quality.

The present invention relates to an industrial fan blade vibration buffer device, comprising a blade petiole and a blade, wherein the blade petiole and the blade are connected via a connecting piece, wherein the connecting piece is formed with left and right concentric sleeves spaced apart from each other, wherein a special-shaped piece is embedded inside the two sleeves, and a vibration-isolating rubber sleeve is sleeved on the special-shaped piece, so that the outer wall of the special-shaped piece and the inner wall of the sleeve are separated by the vibration-isolating rubber sleeve; the blade petiole is inserted between the two concentric sleeves and connected to the shaft between the connecting piece. The present invention realizes a non-rigid connection between the blade petiole and the blade, wherein the rubber buffer absorbs part of the vibration from the blade, thereby improving the working condition of the reduction motor shaft, prolonging the life of the motor, and making the operation quieter.

The invention discloses a transformer vibration reduction optimization method considering temperature, and the method comprises the steps: building an electromagnetic model of a transformer, building a transformer temperature-vibration model, taking the minimum vibration acceleration effective value a as a target based on the relation between the basic size of the transformer and the electromagnetic load and the vibration model, and taking the transformer mass Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax, Gmax and and optimizing and adjusting the iron core diameter D, the number of turns N, the axial height H of the winding and the maximum flux density Bm of the transformer by taking the coil voltage Us as a constraint, and finally solving the optimized D value and H value. According to the transformer designed through the method, at the same working temperature, the vibration noise level of the transformer can be effectively reduced, under the condition that other parameters are not changed, noise can be reduced by 7-10 dB, on the premise that the basic design parameters of the transformer are met, vibration suppression design is conducted on the transformer, the mute performance of the transformer is effectively improved, and the service life of the transformer is prolonged. And safe, mute and stable operation of an electrical system is facilitated.
