A right-angle guide rail and cabinet

Abstract

The invention relates to a right-angle guide rail and a cabinet, belongs to the technical field of guide rails, and solves the problem that an existing right-angle guide rail has poor height adjustment precision, low adjustment efficiency and low reliability and is easy to deviate. The right-angle guide rail comprises a male rail and a female rail. The female rail comprises a base and a slide rail. The base is a cuboid. The slide rail is arranged to the side of the base, and extends in the lengthwise direction of the base. A connecting part is arranged on the upper surface of the base, and theconnecting part is a parallelepiped with a parallelogram-shaped longitudinal section. The male rail is a cuboid, and is provided with a groove matched with the connecting part. The male rail is movably connected with the female rail. The cabinet comprises a cabinet body and a right-angle guide rail. The right-angle guide rail can be accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of guide rails, in particular to a right-angle guide rail and a cabinet. Background technique [0002] At present, a large number of plug-in cabinets are used in power supply products, especially 19-inch standard cabinets. The plug-in cabinets are generally inserted and pulled out along the L-shaped right-angle guide rails installed on the cabinet. With the continuous improvement of use requirements, According to the relevant standards, the gap between the upper and lower adjacent two sub-box panels is generally 0.8mm, and the requirements for the installation accuracy of the sub-boxes in the cabinet are getting higher and higher, especially the requirements for the adjustment of the installation position in the vertical direction are very high. The processing accuracy of the metal cabinet is difficult to guarantee, so a lot of energy is often spent on adjusting the position of the L-shaped right-angle guide...

Problems solved by technology

[0002] At present, a large number of plug-in cabinets are used in power supply products, especially 19-inch standard cabinets. The plug-in cabinets are generally inserted and pulled out along the L-shaped right-angle guide rails installed on the cabinet. With the continuous improvement of use requirements, According to the relevant standards, the gap between the upper and lower adjacent two sub-box panels is generally 0.8 mm, and the requirements for the installation accuracy of the sub-boxes in the cabinet are getting higher and higher, especially the requirements for the adjustment of the installation position in the vertical direction are very high, and the panel The processing accuracy of the metal cabinet is difficult to guarantee, so a lot of energy is often spent on adjusting the position of the L-shaped right-angle guide rail of the subrack when assembling the cabinet. On the other hand, the adjustment clearance of the traditional L-shaped right-angle guide rail is very limited. At present, the traditional L-shaped right-angle guide rail The adjustment is generally to adjust the up and down height of the guide rail through the long round hole on the guide rail. This installation form is difficult to adjust. When the up and down position of the guide rail needs to be adjusted, the sub-box on the guide rail needs to be removed, so as to have room for operation by loosening the fixed guide rail. Screws to adjust the height of the guide rail, then tighten the screws, and then check whether the position of the subrack in the cabinet is appropriate after loading it into the subrack. This adjustment method is extremely inefficient; The friction force of the installation bolts is used to keep the relative position of the guide rails from moving, and the reliability is low. Although the position is temporarily adjusted, the box will sink and shift due to insufficient friction provided by the installation bolts during the vibration process.
