Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pipeline joints, in particular to a hydraulic pipeline quick joint. Background Art

[0002] A quick connector is a connector that can quickly connect or disconnect hydraulic pipes. It is composed of two parts, male and female. When the male and female heads are connected, the pipes are connected. When the male and female heads are disconnected, the pipes are disconnected. The oil cylinder is an important part of the hydraulic system. Fluid is provided to the oil cylinder through the pipe connection. The system cannot occupy too much space, so a compact pipe quick-change connector is used.

[0003] When the existing equipment is in use, the rapid flow of liquid will generate a large amount of impact and vibration force, causing the structure to fall apart. At the same time, too much gas in the pipe will cause the equipment to be over-pressured, making the structure unstable. Therefore, we proposed a hydraulic pipeline quick connector. Utility Model Content

[0004] The utility model aims to provide a hydraulic pipeline quick connector, which solves the problem that the existing equipment will cause the structure to fall apart due to a large amount of impact force and vibration force generated by the rapid flow of liquid when in use, and the problem that the equipment pressure is too large due to excessive gas in the pipe, making the structure unstable, through a fixing mechanism, a valve mechanism and an exhaust mechanism.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a hydraulic pipeline quick connector, comprising a connecting mechanism and a connecting ring, wherein the connecting mechanism comprises a plurality of connecting heads, the outer walls of the plurality of connecting heads are fixedly connected with connecting columns, the outer walls of the connecting columns are provided with a fixing mechanism, the fixing mechanism comprises a fixing shell, the outer wall of the fixing shell is provided with a plurality of fixing grooves, the inner walls of the plurality of fixing grooves are rotatably connected with the connecting columns, the outer wall of the fixing shell is provided with a valve mechanism, the valve mechanism comprises a valve shell, the inner wall of the valve shell is provided with a slide groove, the slide groove is slidably connected with a connecting rod, the outer wall of the connecting rod is fixedly connected with a water retaining block, the outer wall of the valve shell is fixedly connected with a valve shell II, the outer wall of the valve shell II is provided with an exhaust mechanism, the exhaust mechanism comprises an air inlet pipe, the outer wall of the air inlet pipe is fixedly connected with an exhaust valve shell, and the top middle end of the exhaust valve shell is provided with an exhaust hole II.

[0007] Furthermore, the outer wall of the connecting ring is provided with a plurality of threads.

[0008] Furthermore, the fixed shell is provided with a plurality of threaded holes, and the inner walls of the plurality of threaded holes are rotatably connected to the threads provided on the outer wall of the connecting ring.

[0009] Furthermore, a water retaining shell is fixedly connected to the outer wall of the fixed shell, a plurality of water retaining plates are fixedly connected to the outer wall of the water retaining shell, and a plurality of water retaining springs are fixedly connected to the outer walls of the plurality of water retaining plates.

[0010] Furthermore, a lower diverter plate is fixedly connected to the outer wall of the water retaining shell, and a valve baffle is fixedly connected to the outer wall of the lower diverter plate.

[0011] Furthermore, the feature is that an upper diverter plate is fixedly connected to the outer wall of the water retaining shell, and a valve baffle is provided on the outer wall of the upper diverter plate.

[0012] Furthermore, the outer wall of the valve housing 2 is fixedly connected to the exhaust valve housing, the inner wall of the exhaust valve housing is fixedly connected to the sliding rod, the outer wall of the sliding rod is slidably connected to a float, the top of the sliding rod is fixedly connected to a float top block, and the float top block has a plurality of exhaust holes.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with water baffles and water baffle springs. When liquid passes through quickly, it will impact multiple water baffles, causing the water baffles to squeeze the water baffle springs, thereby alleviating the impact and vibration of the water baffles, allowing the water flow to continuously overcome the resistance brought by the water baffles, thereby slowing down the speed of the water flow, thereby achieving the effect of slowing down the flow speed of the liquid and preventing the impact and vibration caused by the rapid flow of the liquid from causing the structure to fall apart.

[0015] 2. The utility model is provided with an exhaust valve, and the gas will enter the exhaust valve housing through the air inlet pipe, and the gas in the pipe will enter the exhaust valve housing through the air inlet pipe. When the gas passes through the exhaust hole, the flow pipe becomes narrower, resulting in compression of the gas, and the flow rate increases to generate noise. When the gas is discharged from the exhaust hole, a vortex is formed due to the sudden increase in the cross-section, thereby increasing the noise generation, so that the gas in the pipe can be quickly discharged, and the structural instability caused by excessive pressure of the equipment due to excessive gas in the pipe can be prevented. At the same time, the noise can be used to remind the staff whether the gas is discharged completely.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] As shown in Figures 2-3, the outer wall of the connecting ring 102 is provided with a plurality of threads 104.

[0029] As shown in Figures 1-6, the fixed shell 201 is provided with a plurality of threaded holes 205, the inner walls of the plurality of threaded holes 205 are rotatably connected with the threads 104 provided on the outer wall of the connecting ring 102, and the threads 104 of the connecting ring 102 rotate along the threaded holes 202 to make the connection tighter.

[0030] Among them Figure 1-2 As shown, the outer wall of the fixed outer shell 201 is fixedly connected to a water retaining shell 203, the outer wall of the water retaining shell 203 is fixedly connected to a plurality of water retaining plates 206, and the outer walls of the plurality of water retaining plates 206 are fixedly connected to a plurality of water retaining springs 204. When the liquid in the tube moves rapidly, the water retaining plates 206 and the water retaining springs 204 can block the liquid and reduce the flow rate of the liquid.

[0031] Among them Figure 1-3 As shown, the outer wall of the water retaining shell 203 is fixedly connected with a lower diverter plate 307, and the outer wall of the lower diverter plate 307 is fixedly connected with a valve baffle 308, which blocks the water retaining block 305 when it descends to a certain depth.

[0033] As shown in Figure 3-6, the outer wall of the valve housing 309 is fixedly connected to the exhaust valve housing 402, the inner wall of the exhaust valve housing 402 is fixedly connected to the sliding rod 403, the outer wall of the sliding rod 403 is slidably connected to the float 404, the top of the sliding rod 403 is fixedly connected to the float top block 405, and the float top block 405 is provided with a plurality of exhaust holes 406. When a large amount of gas in the pipeline is discharged through the exhaust holes 406, noise will be generated due to the increase in cross-sectional area to alert the staff.

[0034] As shown in the figure, a specific application of this embodiment is:

[0035] When the staff needs to use the equipment, they connect the two connectors 101 to the hydraulic pipeline, align the thread 104 on the outer wall of the connecting ring 102 with the thread groove 205 on the outer wall of the fixed shell 201, and let the thread 104 rotate along the inner wall of the thread groove 205 to achieve a tightening effect. At the same time, it will drive the connecting column 103 on the outer wall of the connecting head 101 to move, so that the connecting column 103 and the fixed groove 202 rotate. The same is true for the other connector. At this time, the staff can inject liquid into the hydraulic pipeline. When the liquid passes quickly, it will impact multiple water baffles 206, causing the water baffles 206 to squeeze the water baffle springs 204, thereby alleviating the impact and vibration of the water baffles 206, allowing the water flow to continuously overcome the resistance brought by the water baffles 206, thereby slowing down the speed of the water flow. Subsequently, the liquid with a slowed flow rate will be separated by the upper diverter plate 306 and the lower diverter plate 307 and flow to the valve. At this time, the valve handle 303 can be pulled to drive the connecting rod 302 and the water retaining block 305 to move, thereby opening the valve to allow the liquid to flow. At the same time, the gas in the pipe will enter the exhaust valve housing 402 through the air inlet pipe 401. When the gas passes through the exhaust hole 406, the flow pipe becomes narrower, causing the gas to be compressed, the flow rate increases and noise is generated, and when it is discharged from the exhaust hole 406, a vortex is formed due to the sudden increase in the cross-section, thereby increasing the generation of noise. When the liquid gradually flows into the exhaust valve housing 402, it will cause the float 404 to float and move along the sliding rod 403, and finally block the exhaust hole 407 and the exhaust hole 406 to form a seal. Finally, the liquid will flow into the hydraulic pipeline from the other connector 101.
