[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , the outboard pipe pressure testing device shown includes a pipe sealing assembly 1, a pressure display assembly 2 is threadedly installed in the middle of the upper end of the pipe sealing assembly 1, the lower end of the pipe sealing assembly 1 is provided with a clamping assembly 3, and the lower end of the clamping assembly 3 is threadedly installed with a tightening pressure measuring assembly 4, and the left and right sides of the upper end of the pipe sealing assembly 1 are welded with carrying handles 5. The overall material of the carrying handle 5 is formed by bending two steel bars, so that the operator can better exert force to carry it, so that it can be more convenient during installation and disassembly. The pressure display assembly 2 includes a threaded block 201, a threaded cover 202, a mounting ring 203, a pressure gauge 204 and a soft rubber pad 205. A circle of thread is provided on the outer side of the lower end of the threaded block 201, and the threaded structure of the circle of thread allows the threaded block 201 to be threadedly installed with the pipe sealing assembly 1. The upper end of the threaded block 201 is threadedly installed with a threaded cover 202, and a circle of welding on the outer end of the threaded cover 202 is four tightening blocks, which are convenient for rotating and tightening with leverage. 02 is threadedly connected to the threaded block 201, and a mounting ring 203 is welded to the middle of the upper end of the threaded cover 202. The interior of the mounting ring 203 is a hollow structure, and a valve tube is threadedly installed on the upper end of the mounting ring 203, and a pressure gauge 204 is threadedly installed on the right side of the outer end of the mounting ring 203. The design of the mounting ring 203 is to combine the valve tube and the pressure gauge 204 on the upper end of the mounting ring 203 to form an integral structure. When testing the internal pressure of the outboard tube later, the internal pressure airbag 405 can be injected with pressure measuring gas, and then the valve tube is closed. By observing the changes in the data scale of the pressure gauge 204, the internal pressure changes can be known, thereby completing the pressure test. A soft rubber pad 205 is sleeved and installed below the outer end of the threaded block 201. The inner thickness of the soft rubber pad 205 is only half of the outer thickness. The soft rubber pad 205 can be used to seal the contact end of the threaded block 201 and the sealing plate 101 to ensure the sealing of the structure after installation.

[0029] As a preferred embodiment of the present invention, Figure 1 and Figure 2As shown, the pipe sealing assembly 1 includes a sealing plate 101, a rubber ring 102, a threaded notch 103, a connecting pipe 104, a sealing gasket 105 and a copper gasket 106. The front and rear sides of the upper end of the sealing plate 101 are provided with card holes, and the lower end of the sealing plate 101 is sleeved with a rubber ring 102. The outer side of the lower end of the sealing plate 101 and the inner side of the rubber ring 102 are adapted to each other. Moreover, when the sealing plate 101 is installed to the outboard pipe mouth, the rubber ring 102 can ensure the sealing of the contact end, so that when the pressure test is carried out, no leakage occurs, which affects the accuracy of the pressure test. The middle part of the upper end of the sealing plate 101 is provided with a rubber ring 102. There is a threaded slot 103, and a connecting pipe 104 is installed on the inner thread of the threaded slot 103. A sealing gasket 105 is pasted and installed on the outer side of the upper end of the threaded slot 103. A copper gasket 106 is clamped and installed on the outer side of the sealing gasket 105. There are four copper gaskets 106 symmetrically distributed. The threaded slot 103 can be used to install the thread block 201 on the inner side for reinforcement, and the contact end between the two can improve the sealing between each other through the design of the sealing gasket 105. Subsequently, after the tightening bolt 403 is extended through the copper gasket 106 and then tightened with a nut, the sealing performance between the thread and the threaded slot gap can be guaranteed.

[0030] In the present invention, Figure 3 As shown, the holding component 3 includes a holding disc 301, an anti-wear ring 302, a holding notch 303 and a transmission tube 304. A sticking groove is provided on a circle at the lower end of the holding disc 301. The anti-wear ring 302 is pasted and installed on the inner side of the lower end of the holding disc 301. The anti-wear ring 302 is embedded in the inside of the sticking groove to keep the angle balanced in a straight line. A holding notch 303 is provided on the inner side of the anti-wear ring 302. The middle part of the shape of the holding notch 303 is a circle, and the front and rear sides are rectangular notches. The middle part of the inner side of the holding notch 303 is a circle. A transmission pipe 304 is welded and installed, and the upper end of the transmission pipe 304 passes through the interior of the holding disc 301 and extends to the outside, fitting together with the lower end of the connecting pipe 104 to facilitate subsequent gas transmission; through the holding notch 303 opened at the front end of the holding disc 301, it can be clamped and fixed to the transverse round steel arranged in the middle of the outboard pipe, and then when it contacts the sealing plate 101, due to the presence of the anti-wear ring 302, the wear of the edge ends of the two during the installation process can be reduced, thereby increasing its service life.

[0031] As an embodiment of the present invention, Figure 1 and Figure 4As shown, the tightening pressure measuring assembly 4 includes a positioning flange 401, a tightening pad 402, a tightening bolt 403, a mounting block 404 and a pressure airbag 405. The lower end of the positioning flange 401 is threadedly installed with a tightening pad 402, and the outer side of the lower end of the tightening pad 402 is threadedly installed with a tightening bolt 403. There are four tightening bolts 403 symmetrically distributed. The middle part of the lower end of the tightening pad 402 is welded with a mounting block 404, and the lower end of the mounting block 404 is threadedly installed with a pressure airbag 405, wherein the upper end of the pressure airbag 405 is clamped and installed with a rotating joint, and the pressure airbag 405 as a whole can be folded, expanded and contracted; through the design of the tightening pad 402, when the tightening bolt 403 is used to tighten the positioning flange 401, the edge of the threaded hole at the lower end can be sealed.

[0032] In summary, before starting work, the outboard tube pressure test device is assembled by assembling the back of the clamping disc 301 and the positioning flange 401 together, and then tightening the two by passing the tightening bolt 403 through the threaded hole. Subsequently, the clamping notch 303 provided at the front end of the clamping disc 301 can be clamped and fixed to the transverse round steel arranged in the middle of the outboard tube. When it contacts the sealing plate 101, the presence of the anti-wear ring 302 can reduce the wear of the edge ends of the two during the installation process, thereby increasing their service life. After that, the sealing plate 101 is installed and the tightening bolt 403 is used. After extending through the copper gasket 106, it is tightened with a nut to ensure the sealing performance between the thread gaps. Since the installation contact ends of the device are equipped with sealing structures, the sealing between the device and the outboard tube is very good. After the pressure test work starts, the air inside the outboard tube is evacuated, and the internal pressure airbag 405 starts working and maintains 0.5Mpa. By observing the changes in the scale value of the pressure gauge 204, the internal pressure test status can be known. The whole device is simple and quick to operate, meets the requirements of the outboard tube tightness without damaging the paint, and also ensures the orderly progress of production.
