Handheld standing-wave ratio tester

Abstract

A handheld standing-wave ratio tester disclosed by the present invention comprises a tester body, the two sides of the tester body are fixedly connected with protective frames, the outer wall of the side, away from the tester body, of each protective frame is movably connected with an anti-skid handle, and each protective frame comprises a sweat removing main board and convex blocks installed at the two ends of the sweat removing main board. The back surface of each sweat removing main board is connected with an anti-skid pad, and the outer wall of each anti-skid pad is fixedly connected with the outer wall of the tester body. When the back of the hand abuts against an arc-shaped plate, a bandage can be pulled, an annular air bag is pressed, then air in the annular air bag is blown out of a sweat removing structure, air is blown to the center of the hand, air drying of sweat is accelerated, after an elastic air bag is pressed, the air in the elastic air bag can be guided into a driving device, the driving device extends, and the elastic air bag is driven to rotate. The antiskid plate is pushed out and makes contact with the back of the hand, the contact area is increased, friction force is increased, and the arc-shaped plate is prevented from sliding off from the back of the hand.

Description

technical field [0001] The invention belongs to the technical field of testing devices, in particular to a handheld standing wave ratio tester. Background technique [0002] Standing wave ratio testers measure return loss or standing wave ratio, cable loss and long-distance fault location, which allows us to quickly assess the condition of transmission lines and antenna systems and speed up the installation and commissioning time required for new base stations. It is mainly a lightweight hand-held instrument that provides very simple man-machine interface operation, high sensitivity, and high repeatable results. [0003] Although the standing wave ratio tester can be held in the hand, the shape is still relatively large, and the holding is easy to be unstable. If it is dropped, it will cause great losses. , it is convenient for the user to use the standing wave ratio tester better by setting two handles on both sides of the shell, but it needs both hands to hold the device ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held standing wave ratio tester to solve the problem of the existing hand-held standing wave ratio tester proposed in the above-mentioned background technology. The handle is convenient for the user to use the standing wave ratio tester better, but it needs both hands to hold the device during use, so that it can be held relatively stably, and it is not stable to hold it with one hand, and if the operator is nervous Sweaty palms can also cause the device to slip
