Problems solved by technology

[0003] Due to the large tolerance of the guide rails in the existing drawers, the plug insertion resistance is large at one time. When the drawer is connected to the busbar, the drawer will be skewed, resulting in mechanical damage and affecting the use.

Embodiment Construction

[0026] Such as figure 1 and 2 As shown, a hand-operated three-position positioning drawer push interlock mechanism includes a push mechanism and a three-position positioning mechanism. The push mechanism includes a drive screw 1 mounted on the bottom plate of the drawer through a bracket and a drive screw 1 that coincides with the drive screw 1 to push the drawer to move forward and backward. The groove-shaped positioning part 2 installed on the cabinet body layer can effectively control the linear movement of the drawer through the spiral protrusion of the transmission screw 1 and the chute of the groove-shaped positioning part 2, so as to ensure that the drawer will not move when it is subjected to a reverse force. Skewing occurs due to force, resulting in a dead point of mechanical movement. The propulsion mechanism pushes the drawer to move in the cabinet. When it reaches the designated position, the three-position mechanism positioning mechanism performs three-position p...

Abstract

The invention relates to a low pressure extraction type switch device, in particular to a pushing-interlocking mechanism of a crank three-position locating drawer which comprises a pushing mechanism and a three-position locating mechanism; the pushing mechanism pushes the drawer by a transmission screw and a slot-shaped locating piece; the three-position locating mechanism is a spring pressure locating device and comprises a three-position locating disk, a top locating rod, the elastic ejection mechanism of the top locating rod, and a transmission mechanism; the pushing mechanism drives the three-position locating disk to rotate by the transmission mechanism; a three-position locating slot is arranged on the three-position locating disk; when the three-position locating disk rotates to a corresponding position, the elastic ejection mechanism ejects the top locating rod so as to lead the top locating rod to be embedded into the three-position locating slot for locating the three positions of the pushing mechanism in turn. After the spring pressure device is adopted for locating the three positions of the pushing-interlocking mechanism of the drawer, a light handle resistance indicates an operator, thus clearly locating; compared with the prior locating mechanism, the operation is simplified and meets the safety requirements better.

Description

technical field [0001] The invention relates to a low-voltage withdrawable switchgear, in particular to a hand-operated three-position positioning drawer push interlocking mechanism. Background technique [0002] The power distribution industry is a key industry in the country. The reliability and safety of equipment applications are related to economic development and the safety of life and property. At the same time, the technical feasibility of each product needs to be applied to equipment. Low-voltage switch complete sets of equipment have a wide range of applications. In most places of application, the operating electrician does not fully understand the functions of the equipment, especially the three-position program and three-position function electrical requirements of the drawer in the low-voltage withdrawable switch complete set of equipment. Misoperation It is mainly reflected in the unclear concept of the mechanical three-position program. After the drawer push m...
