Gap adjustment mechanism between devices in cabinet

Abstract

The invention discloses a gap adjustment mechanism between devices in a cabinet. The gap adjustment mechanism comprises the cabinet and the devices. The gap adjustment mechanism between the devices is composed of adjustment units, stand columns, support plates and drawable guide rail parts, wherein each adjustment unit is composed of oblong holes, a fixed frame, an adjustment screw rod and an adjustment screw block; the oblong holes are formed in the upper part and the bottom of the fixed frame; the adjustment screw block is assembled on the adjustment screw rod; the upper and lower ends of the adjustment screw rod penetrate the oblong holes; the adjustment block is located in the fixed frame and fixed through the adjustment screw rod; the bottom of the adjustment screw block extends outwards to form a support surface; the drawable guide rail is supported and fixed on the support surface; the adjustment units are fixed to the front, back, left and right stand columns of the cabinet and connected with the support plates mounted on the left and right sides transversely in the cabinet; the drawable guide rails are fixed to the left and right support plates; and first guide rails are mounted on the left and right sides of each device. According to the technical scheme, the first-pass yield of production assembly is increased; and the number of construction personnel can be changed to two from three due to simple and convenient operation, so that the production cost is reduced.

Description

technical field [0001] The invention relates to a gap adjustment mechanism, which is especially suitable for communication, post and telecommunications, multimedia and other fields, and is used for adjusting the gap between devices when the devices are integrated into a cabinet and installed. Background technique [0002] In system engineering in the fields of communication, post and telecommunications, multimedia, etc., it is often necessary to integrate many devices together. For the convenience of use, they are generally placed in standard cabinets (such as national standard 19-inch cabinets). These integrated devices are generally fixed on the column of the cabinet through pullable guide rails, and the devices can be pushed or pulled out through pullable guide rails, which is convenient for use, inspection and maintenance. [0003] According to the national standard of the cabinet, the gap between the panels of the upper and lower adjacent equipment is generally 0.8 mm t...

AI Technical Summary

Problems solved by technology

When the distance is large, add a backing plate to adjust to reduce the distance; if the distance is small, it cannot be adjusted, and the relevant parts are scrapped and reprocessed

[0005] Due to the large size of the cabinet (up to 2 meters in height), there are many assembly parts and processes, and the cumulative tolerance is large, it is difficult to ensure that it is assembled in one piece. Therefore, the traditional adjustment method has limitations and cannot fully guarantee the smooth installation of the integrated equipment.
