Mechanical rack with sliding groove

Abstract

The mechanical rack with the sliding grooves comprises a rack body located at the top of an installation bottom plate, the sliding grooves are formed in the two sides of the rack body, the two sides of the top of the installation bottom plate are fixedly connected with guide bases, and the surfaces of the guide bases are connected with the inner surfaces of the sliding grooves in a sliding mode. When lubricating liquid needs to be injected between the guide seat and the sliding groove, only a threaded liquid injection barrel needs to be rotated, so that the threaded liquid injection barrel rotates on the inner surface of a threaded inner barrel, the threaded liquid injection barrel drives a liquid drainage pipe to move downwards to make contact with the inner surface of a flow guide main groove, and the lubricating liquid is injected into the threaded liquid injection barrel; lubricating liquid enters the main flow guide groove through the liquid drainage hole, then the rack is moved back and forth, the lubricating liquid is guided in the main flow guide groove and finally can flow out of the branch flow guide grooves, then the sliding groove is lubricated, after lubrication is completed, the threaded liquid injection cylinder is rotated reversely, the liquid drainage pipe leaves the main flow guide groove, and the lubricating liquid can be injected conveniently; and the movement fluency of the rack is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of racks, in particular to a mechanical rack with a sliding groove. Background Art

[0002] A rack is a special gear with teeth distributed on a bar-shaped body. Racks are divided into spur racks and helical racks, which are used in pairs with spur cylindrical gears and helical cylindrical gears respectively; the tooth profile of the rack is a straight line rather than an involute (it is a plane for the tooth surface).

[0003] When a rack with a slide groove moves, it needs to slide with the guide seat and the slide groove to play a guiding and supporting role. However, there may be a jam at the sliding connection, which reduces the smoothness of the rack movement. For this reason, we propose a rack with a slide groove that can easily inject lubricating fluid to solve the above-mentioned shortcomings. Utility Model Content
