Problems solved by technology

[0004] The purpose of the present invention is to provide a support device with signal shielding that is convenient for the operation of the oscilloscope, so as to solve the problem that the oscilloscope proposed in the above background technology is placed on the ground, and the staff needs to squat up many times, which is very inconvenient to operate. Most of the support frames of some wave recorders are fixed at a certain place, but the position of the wave recorder needs to be changed many times during use, so the existing support frames cannot meet the problem of use

Embodiment 1

[0024] see Figure 1-6 This embodiment provides a support device with signal shielding to facilitate the operation of the oscilloscope, including a support base 1, the top of the inner wall of the support base 1 is fixedly connected with a hinged base 2, and the bottom of the hinged base 2 is hinged with an air pressure rod 3, the air pressure rod The bottom of the base plate 3 is fixedly connected with a base plate 4, the bottom of the base plate 4 is provided with a universal wheel 5, the bottom of the base plate 4 is fixedly connected with a support assembly 6, the top of the support base 1 is fixedly connected with a baffle plate 7, and the top of the support base 1 is provided with Sliding groove 8, the inner wall of sliding groove 8 is fixedly connected with rotating seat 9, the inner wall of rotating seat 9 is connected with screw rod 10 in rotation, and screw rod 10 runs through support seat 1 and extends to the outside of support seat 1, and screw rod 10 is away from r...

Embodiment 2

[0027] see Figure 1-6 , made a further improvement on the basis of Embodiment 1: the support assembly 6 includes a support tube, the inner wall of the support tube is threadedly connected with a support leg, and the bottom of the support leg is fixedly connected with a buffer block, and the buffer block is in the shape of an isosceles trapezoid By rotating the supporting legs, the buffer block can be separated from the ground, so that the universal wheel 5 can land on the ground, which facilitates its transfer, and the buffer block is set to an isosceles trapezoid to increase its contact area with the ground. Make the support more stable.

[0028] Wherein, the top of the support seat 1 is fixedly connected with the limit bar 18, the bottom of the wave recorder body 17 is provided with a shielding layer 19, the shielding layer 19 is slidably connected with the limit bar 18, and the shielding layer 19 is an antistatic plate, which plays a role in preventing static electricity. ...

Embodiment 3

[0030] see figure 1 , image 3 or Figure 5 , on the basis of Embodiment 1, a further improvement has been made: the top of the bottom plate 4 is fixedly connected with a placement box 21, the placement box 21 is a rubber box, and the surface of the placement box 21 is provided with antistatic rubber, and the top of the inner wall of the support seat 1 is fixedly connected There is a cover plate 22, the bottom of the cover plate 22 is fixedly connected with a spring 23, and the bottom of the spring 23 is fixedly connected with a pressure plate 24. During use, the equipment that needs to be used during the operation can be placed in the storage box 21, which is more convenient The operator uses it, and during the transfer of the support device, the cover plate 22 covers the storage box 21, and then under the joint action of the spring 23 and the pressure plate 24, it can effectively protect the equipment and prevent collisions during the transfer process. Among them, the anti...

Abstract

The invention discloses a support device with signal shielding and convenient for a waveform recorder to operate. The device comprises a support base; a hinge base is fixedly connected with the top ofthe inner wall of the support base; a pressure bar is hinged to the bottom of the hinge base; a bottom plate is fixedly connected with the bottom of the pressure bar; universal wheels are arranged atthe bottom of the base plate; a support device is fixedly connected with the bottom of the base plate; a baffle plate is fixedly connected with the top of the support base; a sliding groove is formedin the top of the support base; a rotation base is fixedly connected with the inner wall of the sliding groove; a lead screw is rotationally connected with the inner wall of the rotation base; and the lead screw penetrates through the support base and extends to the outside of the support base. According to the device provided by the invention, the problem that if the waveform recorder is placedon the ground, a staff needs to squat down and stand up for many times, so that the waveform recorder is extremely inconvenient to operate, and now, most existing waveform recorder support frames arefixed at certain places, but when in use, the waveform recorder needs to be dislocated for many times, and thus the existing support frames cannot meet the requirement of usage is solved.

Description

technical field [0001] The invention relates to the technical field of wave recorders, in particular to a support device with signal shielding for easy operation of wave recorders. Background technique [0002] Portable waveform recorder, also known as wave recorder, is a transient signal recording instrument developed for power system applications. The internal software of the instrument is preset with a test template for generator debugging, so that users can easily complete the short circuit of the generator through the recorder. Characteristic test, no-load characteristic test, excitation system disturbance test, excitation system 10% step test, de-excitation constant measurement, auto-synchronization device calibration, unit load shedding record and other tests. [0003] Most of the existing oscilloscopes can shield the interference from the external environment. When in use, due to the large volume of the oscilloscope, most of them are placed on the ground or on a supp...
