Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the invention easy to understand, the invention is further explained below with reference to the specific embodiments, but the following embodiments are only the preferred embodiments of the invention, not all. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

as shown in fig. 1-4, a buckle type escalator step chain dustproof device comprises an escalator truss main body 1, wherein a plurality of groups of middle standard dustproof plates 2 are placed in the escalator truss main body 1, placing grooves 3 are formed in both sides of the escalator truss main body 1, both ends of the middle standard dustproof plates 2 are embedded in the placing grooves 3, and clamping springs 4 are arranged at the left ends of the middle standard dustproof plates 2;

during the use, put into middle part standard dust guard 2 along standing groove 3 on staircase truss main part 1, then when with last one section concatenation, insert one section middle part standard dust guard 2 in the back on one section middle part standard dust guard 2, make two sets of middle part standard dust guards 2 carry out the prepositioning under the effect of pressing from both sides spring 4, then fix through connecting angle type spare 6, so on, every section is all spliced through the above-mentioned operation of repetition, thereby effectively improved the installation effectiveness of middle part standard dust guard 2, also be convenient for later stage dismantlement and maintenance simultaneously.
