DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0026] like Figures 1-2 As shown, a pocket-sized pressing tool comprises a bottom bin 1 and a top cover 2. A detachable top cover 2 is provided on the bottom bin 1, and the top cover 2 is provided with an inner groove 24 that matches the flange 14 of the bottom bin 1. The top cover 2 and the bottom bin 1 are quickly assembled through the cooperation of the inner groove 24 and the flange 14, and then fixedly connected by bolts evenly distributed on the edge of the top cover 2. A pressing mechanism 3 is provided on one side of the top cover 2, and an infusion mechanism 4 is provided on the other side. The pressing mechanism 3 comprises a pressing rod 22 and a liquid pumping mechanism, one end of the pressing rod 22 is rotatably connected to the top cover 2, and the other end is slidably connected to the liquid pumping mechanism, and the bottom of the liquid pumping mechanism is integrated with the top cover 2 and connected to the bottom bin 1. The pressing mechanism 3 extracts the test pressure liquid in the bottom bin 1 and continuously transports it to the pressure test equipment through the infusion mechanism 4 for pressurization.

[0027] like Figures 3 to 6 As shown, the outer side of the bottom bin 1 is provided with a plurality of evenly distributed reinforcing ribs 13. During the operation and pressurization process, the bottom bin 1 is subjected to a large pressure, and the reinforcing ribs 13 can improve the ability of the bottom bin 1 to withstand pressure without deformation. A side of the bottom bin 1 close to the top cover 2 is provided with a side groove 12, and a sealing ring 15 is provided in the side groove 12. The sealing ring 15 can improve the sealing of the assembly of the top cover 2 and the bottom bin 1. A boss 21 is provided on the top cover 2, and a pressing mechanism 3 is provided on the boss 21. The boss 21 can improve the anti-deformation ability of the top cover 2.

[0028] The pumping mechanism includes a guide tube 31, a lifting rod 32 and a connecting piece 23. An air hole 311 is provided at the top of the guide tube 31, a lifting rod 32 is provided inside the guide tube 31, and a rubber bowl 34 is provided at the bottom end of the lifting rod 32. The lifting rod 32 moves along the guide tube 31 and drives the rubber bowl 34 to move. The edge of the rubber bowl 34 fits with the inner wall of the guide tube 31. When the lifting rod 32 drives the rubber bowl 34 to move upward, air enters the guide tube 31 through the air hole 311 and the gap between the rubber bowl 34 and the inner wall of the guide tube 31; when the lifting rod 32 drives the rubber bowl 34 to move downward, the edge of the rubber bowl 34 is deformed and fits tightly with the inner wall of the guide tube 31, so that the air in the guide tube 31 is discharged into the bottom bin 1, thereby continuously increasing the air pressure in the bottom bin 1, so that the pressure test liquid in the bottom bin 1 is transported to the infusion mechanism 4. A spring 33 is provided between the rubber bowl 34 and the inner top wall of the guide cylinder 31. Under the action of the spring 33, the lifting rod 32 has a tendency to move downward, so that the lifting rod 32 has the function of automatically moving downward. The top end of the lifting rod 32 is rotatably connected to the connecting piece 23, and the connecting piece 23 is provided with a through hole that matches the pressure rod 22. In the process of rotating the pressure rod 22, the connecting piece 23 moves along the pressure rod 22, and the angle between the connecting piece 23 and the lifting rod 32 changes accordingly.

[0029] A check plate 35 is provided at the position of the top cover 2 corresponding to the liquid extraction mechanism. One side of the check plate 35 is connected to the top cover 2 through a rotating shaft, and the rotating shaft is provided with a torsion spring. A groove 351 matching the check plate 35 is provided on the top cover 2. Under the action of the torsion spring, the check plate 35 tends to block the liquid extraction mechanism and the bottom bin 1. When the air pressure in the guide cylinder 31 is relatively high, the check plate 35 opens to allow the air flow to enter the bottom bin 1; when no air is introduced, the check plate 35 isolates the guide cylinder 31 from the bottom bin 1 to prevent the pressure test liquid from flowing back into the guide cylinder 31.

[0030] The pressure rod 22 is provided with a handle 222 at one end close to the pumping mechanism, and a plurality of force rods 221 at the other end. The top cover 2 is provided with support columns 211 corresponding to the plurality of force rods 221, and the force rods 221 are rotatably connected to the support columns 211. When the pressure rod 22 is rotated, the force rod 221 and the support column 211 are used as fulcrums for rotation. The plurality of force rods 221 and the support rods facilitate the dispersion of the pressure applied by the pressure rod 22 to the top cover 2.

[0031] like Figures 6-7As shown, the infusion mechanism 4 includes an infusion tube 41, a hose 43 and a connecting tube 44. The top cover 2 is provided with a first opening 25 for matching the infusion tube 41. One end of the infusion tube 41 extends into the bottom of the bottom bin 1, and the other end is connected to the hose 43, and the other end of the hose 43 is connected to the connecting tube 44. One end of the connecting tube 44 is provided with a hydraulic valve, and the other end is connected to the device to be tested through a third joint 441. The third joint 441 is detachably connected to the connecting tube 44 through a thread, which is convenient for replacing a matching joint according to different devices to be tested. The test pressure fluid flows from the infusion tube 41 to the hose 43, then enters the connecting tube 44 through the hose 43, and finally enters the device to be tested, and the hydraulic valve measures the strength of the hydraulic pressure. The two ends of the hose 43 are respectively connected to the infusion tube 41 and the connecting tube 44 through a detachable first joint 431 and a detachable second joint 432. The detachable first joint 431 and the second joint 432 are convenient for adapting to hoses 43 of different diameters and replacing them.

[0032] A one-way valve 411 is provided at one end of the infusion tube 41 close to the hose 43. The one-way valve 411 ensures that the pressure test fluid flows from the infusion tube 41 to the hose 43 in one direction. A pressure relief pipe 42 is provided on the one-way valve 411, and a second opening 26 matching the pressure relief pipe 42 is provided on the top cover 2. A valve 421 and a perspective window 422 are provided on the pressure relief pipe 42. At the initial stage of pressure testing, open the valve 421 to allow the pressure test fluid to flow into the pressure relief pipe 42, and observe whether the pressure relief pipe 42 is unobstructed through the perspective window 422. After closing the valve 421, the pressure test fluid flows to the equipment to be tested. After pressurizing to the specified pressure and time, before disassembling the tooling, open the valve 421 first to allow the high-pressure pressure test fluid to flow back into the bottom bin 1 to prevent the pressure test fluid from splashing due to excessive hydraulic pressure.

[0033] The working principle of the specific implementation of the utility model is as follows: the pressure rod 22 is rotated with the support column 211 as the fulcrum, and the pressure rod 22 drives the lifting rod 32 to move up and down along the guide tube 31, and the lifting rod 32 drives the rubber bowl 34 to pump air into the bottom bin 1. The air pressure in the bottom bin 1 increases, and the pressure test liquid is squeezed into the infusion tube 41. The pressure test liquid passes through the one-way valve 411 and enters the hose 43, and then enters the connecting pipe 44 through the hose 43, and finally enters the device to be tested. The hydraulic gauge 442 monitors the pressure change in real time. After the pressure measurement is completed, the pressure is released through the pressure relief pipe 42.
