Embodiment Construction

[0013] Such as figure 1 It is a schematic diagram of the structure of the stability test bench, which is mainly composed of a rack platform (6), a test bench (10), a manual inclination setting mechanism, and a motor slow-rotation mechanism. The manual inclination setting mechanism is mainly composed of a manual Wheel (17), screw transmission box (16), left limit nut (18), right limit nut (14), mounting frame (15), connector (13), support shaft (12), support plate (8 ), a bearing seat (9), and an inclination pointer (7); Group (4) constitutes.

[0014] The test bench (10) is connected on the support plate (8), the support shaft (12) is a cross shaft and fixed on the frame platform (6) through the bearing seat (9) , the fulcrum (12) can swing and pass through the frame platform (6), and the upper end of the fulcrum (12) is bolted to the support plate (8). The motor slow-rotating mechanism is located below the support plate (8), and the worm gear reducer (2) of the motor slow-...

Abstract

The invention relates to the stability test device for the household appliances and the electric appliances for similar purposes, in particular to a stability test bed. The stability test bed is mainly composed of a frame platform, a test bed plate, a hand-operated inclination angle setting mechanism and a motor slow-rotation mechanism, wherein the hand-operated inclination angle setting mechanism is mainly composed of a screw transmission case, a limiting nut, a mounting frame, a connector, a supporting shaft, a supporting plate and a bearing block; the motor slow-rotation mechanism is mainly composed of a motor, a worm wheel-worm reduction box, a mounting plate and a transmission group; the test bed plate is connected to the upper surface of the supporting plate; the supporting shaft isfixed to the frame platform through the bearing block, and is capable of swinging and penetrates through the frame platform; the upper end of the supporting shaft is connected to the supporting platethrough a bolt; the motor slow-rotation mechanism is located on the lower surface of the supporting plate; the worm wheel-worm reduction box is fixedly connected to the upper end of the supporting shaft through the mounting plate; the screw transmission case is fixed to the lower surface of the frame platform through the mounting frame; and the lower end of the supporting shaft is articulated to a screw in the screw transmission case through the connector.

Description

technical field [0001] The invention relates to a stability test device for household electrical appliances and similar electrical appliances, in particular to a stability test bench that can fully meet the test requirements of the IEC60335-1 international standard. Background technique [0002] The general requirements of the international standard "Safety of Household and Similar Electrical Appliances" (IEC60335-1) point out that: Except for fixed appliances and hand-held appliances, appliances intended to be used on a surface such as the floor or table should have sufficient stability. sex. The appliance shall not fall over when it is placed on an inclined plane 10° from the horizontal in any normal use position in use; the appliance with heating elements shall not be turned over when the inclination angle increases to 15°. fall. Relevant domestic standards and certification standards such as TüV, GS, and GE also have corresponding requirements for the stability of elec...
