Description

Vacuum gauge for cold plasma body surface modification treatment instrument

Technical Field

The utility model relates to the field of vacuum gauge devices, in particular to a vacuum gauge for a cold plasma surface modification treatment instrument.

Background

A Vacuum Gauge (Vacuum Gauge), also known as a Vacuum Gauge, is an instrument that measures Vacuum or air pressure. The measurement of the gas pressure is generally performed by using the variation of some physical effect of the gas at different pressures. Widely used in scientific research and industrial production.

At present, the vacuum gauge needs to be connected with a controller through a data line during use, but the data line is prone to loosening during use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a vacuum gauge for a cold plasma surface modification treatment instrument, which can avoid the data line from loosening.

The technical scheme of the utility model is as follows:

the vacuum gauge for the cold plasma surface modification treatment instrument comprises a vacuum gauge body, wherein a connection fastening device is arranged at the socket end of a data wire of the vacuum gauge body; the connecting and fastening device comprises fastening pieces which are oppositely arranged on two sides of the socket end.

The fastener includes the anchorage bar, and the anchorage bar top is equipped with the briquetting.

The pressing block can be rotatably arranged on the fastening rod.

The pressing block comprises a first transverse section connected with the fastening rod and a second transverse section which is exposed at the exposed end of the first transverse section and can be transversely and rotatably connected with the first transverse section.

And a screw is arranged at the inner side end of the pressing block.

And a pressure plate is arranged at one end of the screw rod inserted into the pressure block.

The utility model has the beneficial effects that: the data wire inserted into the socket is fastened through the connecting and fastening device, so that the data wire is not easy to loosen; the inserting end of the data line is pressed down and limited by the fastener.

Drawings

The foregoing and other objects, features, and advantages of the utility model will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Wherein: FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the screw structure of the present invention;

FIG. 3 is a schematic view of a second cross-section of the present invention;

in the attached drawing, 1 is the vacuum gauge body, 2 is the data line socket end, 3 is the fastener, 4 is the anchorage bar, 5 is the briquetting, 6 is first horizontal segment, 7 is the second horizontal segment, 8 is the screw rod, and 9 is the pressure disk.

Detailed Description

Referring to fig. 1, the vacuum gauge for the cold plasma surface modification treatment instrument comprises a vacuum gauge body 1, wherein a connection fastening device is arranged at a data wire socket end 2 of the vacuum gauge body; the connecting and fastening device comprises fastening pieces 3 which are oppositely arranged at two sides of the socket end. The data wire inserted into the socket is fastened through the connecting and fastening device, so that the data wire is not easy to loosen; the inserting end of the data line is pressed down and limited by the fastener.

The fastener includes fastening rod 4, and the fastening rod top is equipped with briquetting 5. The data line plug-in end is pressed down and fixed through the pressing block.

The pressing block can be rotatably arranged on the fastening rod. The pressing block rotates to enable the data wire plug-in end to be conveniently inserted into the socket.

The pressing block comprises a first transverse section 6 connected with the fastening rod and a second transverse section 7 which is arranged on the exposed end of the first transverse section and can be transversely and rotatably connected with the exposed end of the first transverse section. The second transverse section can rotate around the joint; when the data line needs to be installed, the second transverse section rotates outwards, so that the data line can be conveniently inserted; when the data line is inserted into the socket, the second transverse section is rotated inwards to limit the data line.

And a screw 8 is arranged at the inner side end of the pressing block. Through setting up the screw rod to the screw rod twists and pushes down, makes to compress tightly the effect better.

And a pressure plate 9 is arranged at one end of the screw rod inserted into the pressure block. The pressure plate adopts a conical structure. The conical structure is adopted, so that the pressure is more concentrated, and the fixing effect is better.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
