Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present utility model, a portable wireless signal analyzer includes an analyzer main body 1, and a shielding mechanism 2 for shielding is disposed at a touch screen of the analyzer main body 1. The arrangement of the protection mechanism 2 shields the touch screen on the analyzer main body 1, so that the analyzer main body is prevented from being knocked and damaged by other tools in the knapsack after being stored.

The protection mechanism 2 comprises a limiting component 21 and a covering component 22, wherein the limiting component 21 is arranged on the top outer wall of the analyzer main body 1.

The limiting assembly 21 comprises a fixing strip 211 integrally arranged on the outer wall of the top of the analyzer body 1, and a cavity is formed in the fixing strip 211. The cavity is slidably connected with a movable plate 212, and a plurality of limiting columns 213 for clamping limiting are linearly distributed on the side wall of the movable plate 212. The number of the plurality of stopper posts 213 is two to six, and three are used in the present embodiment.

The cover assembly 22 comprises a cover plate 221, sliding strips 223 are symmetrically arranged on the inner wall of the cover plate 221, and a convex plate 222 is integrally arranged at the top end of the cover plate 221. The side wall of the convex plate 222 is fixedly connected with a wedge-shaped plate 224, and an adjusting piece for canceling limit is arranged on the wedge-shaped plate 224. The wedge plate 224 is arranged so that the cover assembly 22 is movably pressed between the inclined surface and the limiting post 213 during the covering operation.

The front shell wall of the analyzer main body 1 is symmetrically provided with sliding grooves which are in sliding connection with the sliding strips 223. The top housing wall of the analyzer body 1 is provided with a recess for receiving the boss 222. The arrangement of the chute and the slide 223 facilitates the connection of the cover assembly 22 to the analyzer body 1.

One end of the plurality of limiting columns 213 far away from the moving plate 212 penetrates through the corresponding side wall of the fixed strip 211 and is connected with balls in a rolling mode, and the limiting columns 213 are sleeved with first springs for resetting adjustment. The first spring is arranged to facilitate the clamping of the limiting column 213 to the wedge-shaped plate 224 during use.

The wedge plate 224 is linearly provided with a plurality of limit grooves, and the limit grooves are clamped and limited with the limit posts 213.

The adjusting piece comprises push columns 225 movably connected in the limiting grooves, and one ends, far away from the limiting grooves, of the plurality of push columns 225 are connected with connecting plates 226. Wherein, a plurality of springs two 227 for resetting adjustment are connected between the connecting plate 226 and the wedge-shaped plate 224.
