Embodiment Construction

[0014] Example: refer to figure 1 , 2 As shown, a shaft shield includes a telescopic shield 1 and a base 2, and the two sides of the top surface of the base 2 are respectively provided with linear tracks 3 for sliding the telescopic shield, and the telescopic shield 1 includes several rectangular plates 1-1 , the cross stretcher 1-2 and the roller 1-3, the rectangular plates 1-1 are arranged from large to small, the plate and the plate are connected by the cross stretcher 1-2, the roller 1-3 is located under the rectangular plate 1-1 and It can slide on the linear track 3, and by adding rollers 1-3, the direct friction between the telescopic cover 1 and the linear track 3 is reduced, thereby prolonging the service life. The rectangular plate 1-1 is connected with the cross expander 1-2 through screws, which is convenient to install and easy to disassemble, which greatly improves the work efficiency. The rectangular plate 1-1 is made of stainless steel material.

Abstract

The invention discloses a shaft shield. The shaft shield comprises a retractable shield and a base, wherein a linear guide rail where the retractable shield slides is arranged on each of two sides on the top of the base. The shaft shield is characterized in that the retractable shield comprises a plurality of rectangular plates, crossed expansion pieces and rollers, wherein the rectangular plates are arranged in descending order; every two plates are connected through the crossed expansion pieces; and the rollers are positioned below the rectangular plates and can slide on the linear guide rails. The shaft shield has the advantages of simple structure, convenience for assembling and simplicity for disassembling; the working efficiency is greatly improved; the rollers are provided, so that the direct friction between the retractable shield and the linear guide rails is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a protective cover, in particular to a shaft guard. Background technique [0002] In the existing shaft guard, in order to reduce the friction between the telescopic guard and the linear slide rail and prolong its service life, it is usually used to apply lubricating oil on the surface of the linear slide rail, but because the linear rail often has dust or other impurities, The surface of the linear track is more likely to be polluted, so that the lubricating oil injection port is easily blocked, resulting in a reduction in the amount of lubricating oil, thereby affecting its service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shaft guard with simple structure, long service life and easy maintenance. [0004] The technical solution of the present invention is: a shaft shield, including a telescopic shield and a base, linear rails for the sliding of the ...
