DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1 , a high-pressure pipeline connector, comprising a connecting sleeve 1 and a high-pressure pipe 2, wherein the high-pressure pipe 2 is used for connecting a high-pressure device; Reference Figure 1 , Figure 2 , Figure 6-Figure 8 A threaded groove (drawn in the figure but not marked) is provided on the connecting sleeve 1, a threaded sleeve 5 is threadedly installed on the threaded groove, a plurality of connecting rods 4 are fixedly installed on the threaded sleeve 5, a pressure relief pipe 3 is fixedly installed between the plurality of connecting rods 4, and the pressure relief pipe 3 is slidably installed in the connecting sleeve 1, a sealing ring 17 is fixedly installed in the pressure relief pipe 3, a sealing ring sleeve 16 is fixedly installed on the sealing ring 17, when the device needs to be used, first pass one end of the high-pressure pipe 2 through the sealing ring sleeve 16, and press it against the sealing ring 17, and the inner diameter of the high-pressure pipe 2 is equal to the diameter of the sealing ring sleeve 16, so that the high-pressure pipe 2 can be sealed and clamped on the sealing ring sleeve 16.

[0039] Reference Figure 3-Figure 5, a plurality of rod bodies (drawn in the figure but not marked) are fixedly installed on the pressure relief pipe 3, a fixed disk 10 is fixedly installed between the plurality of rod bodies, and the fixed disk 10 is slidably installed in the connecting sleeve 1, a plurality of slide grooves (drawn in the figure but not marked) are opened on the fixed disk 10, a plurality of slide grooves are fixedly installed with columnar springs 14 (drawn in the figure but not marked), a plurality of columnar springs 14 are fixedly installed with slide rods 9, and a plurality of slide rods 9 are slidably installed on the corresponding slide grooves, a plurality of slide rods 9 are fixedly installed with conical springs 11, a plurality of conical springs 11 are fixedly installed with push rods 8, a plurality of push rods 8 are fixedly installed with abutments 12, a plurality of abutments 12 are fixedly installed with clamps 13, and a plurality of limit blocks 7 are fixedly installed in the connecting sleeve 1.

[0040] When one end of the high-pressure pipe 2 is pressed horizontally against the right side of the sealing ring 17 (such as Figure 8 The threaded sleeve 5 is then manually rotated so that the threaded sleeve 5 drives the multiple connecting rods 4 and the pressure relief pipe 3 to move to the left (as shown in the direction of FIG. Figure 3 In the process of the pressure relief pipe 3 moving to the left, the plurality of rod bodies, the fixing plate 10, the plurality of slide bars 9 and the plurality of push rods 8 cooperate to drive the plurality of blocks 12 and the plurality of clamping plates 13 to move to the left together. In the process of the plurality of blocks 12 moving to the left, the plurality of limit blocks 7 act on the upper ends of the corresponding blocks 12 (such as Figure 5 The influence of the resistance force (in the direction shown) will cause the multiple resistance blocks 12 to move along the inclined surface of the corresponding limit block 7, driving the corresponding clamping plate 13 to move to one side of the high-pressure pipe 2 until the multiple clamping plates 13 cooperate to clamp and fix the high-pressure pipe 2; During this process, the fixed plate 10 starts to drive the plurality of slide bars 9 to move to the left (eg Figure 5 As shown in the direction, due to the influence of the resistance of the multiple limit blocks 7 to the corresponding stop blocks 12, the multiple slide bars 9 will first squeeze the corresponding conical springs 11. When the squeezing force of the multiple conical springs 11 can make the multiple stop blocks 12 overcome the resistance of the corresponding limit blocks 7, the multiple slide bars 9 will cooperate with the corresponding conical springs 11 and the push rods 8 to make the multiple stop blocks 12 move downward along the inclined surface of the corresponding limit blocks 7 (as shown in the direction shown in the direction). Figure 5 direction shown).

[0041] At the same time, after the multiple clamping plates 13 cooperate to fix the high-pressure pipe 2, when the multiple conical springs 11 are still elastic, it is necessary to continue to rotate the threaded sleeve 5 manually, so that the fixing plate 10 drives the multiple sliding rods 9 to continue to move to the left to squeeze the corresponding conical springs 11, until the multiple conical springs 11 are compressed to the maximum compression amount they can withstand, and cannot be compressed further, then the multiple clamping plates 13 can be locked to prevent the multiple clamping plates 13 from rebounding due to the elastic force of the corresponding conical springs 11, that is, effectively strengthen the effect of the multiple clamping plates 13 cooperating to clamp and fix the high-pressure pipe 2; And when the pressure relief pipe 3 is forced to move to the left (such as Figure 3 As shown in the direction, the sealing ring 17 inside it will push the high-pressure pipe 2 to move to a certain extent. When the multiple clamps 13 cooperate to fix the high-pressure pipe 2, that is, the position of the high-pressure pipe 2 relative to the connecting sleeve 1 is fixed, when the pressure relief pipe 3 continues to move, the sealing ring 17 (such as Figure 8 In the direction shown, the right side of the sealing ring 17 has a certain elasticity and can be squeezed and deformed by force, but the left side thereof is not elastic, so as to facilitate the subsequent connection with the pipeline).

[0042] At the same time, when the multiple slide bars 9 are forced to move downward, the movement of the multiple slide bars 9 and the limitation of other components on the multiple slide bars 9 can be achieved through the cooperation of the multiple slide grooves and the corresponding cylindrical springs 14.

[0043] An anti-skid pad (not shown in the figure) is fixedly installed on one side of the multiple clamping plates 13 close to the high-pressure pipe 2. When the multiple clamping plates 13 cooperate to clamp the high-pressure pipe 2, the multiple anti-skid pads can effectively increase the friction between the multiple clamping plates 13 and the high-pressure pipe 2, that is, the multiple clamping plates 13 cooperate to clamp the high-pressure pipe 2 stably.

[0044] Reference Figure 1 , Figure 2 , Figure 8 , Fig.10 , Fig.11 The pressure relief pipe 3 is sealed and fixedly installed with a connecting pipe 6, which is used to connect with valves, equipment, other pipeline systems, etc. The connecting pipe 6 is fixedly connected with a connecting pipe 18, and one end of the connecting pipe 18 is sealed and fixedly installed on the sealing ring 17 (such as Figure 8 As shown, the right end of the connecting pipe 18 is fixedly installed on the left side of the sealing ring 17, and the inner diameter of the connecting pipe 18 is larger than the diameter of the sealing ring sleeve 16, which effectively ensures that the liquid or gas entering the high-pressure pipe 2 can enter the connecting pipe 18.

[0045] Reference Figure 8-Figure 12 , Fig.15 , Fig.16 A pressure relief baffle 26 is sealed and slidably installed on the connecting pipe 18, a bracket 32 ​​is fixedly installed in the pressure relief pipe 3, a nut 33 is fixedly installed on the bracket 32, a screw 36 is threadedly installed on the nut 33, an adjusting disk 34 is rotatably installed on the lower end of the screw 36, and a spring 35 is fixedly installed between the adjusting disk 34 and the pressure relief baffle 26.

[0046] Reference Figure 1 The connecting sleeve 1 is provided with a circular hole 1, and the pressure relief pipe 3 is provided with a circular hole 2 (drawn but not marked in the figure, from Figure 8As can be seen in the figure, and the apertures of the circular hole 1 and the circular hole 2 are the same, when the device needs to be used, the distance between the pressure relief baffle 26 and the adjustment disk 34, that is, the amount of compression of the spring 35 (the amount of compression refers to the degree of deformation of the spring 35 after being compressed by an external force) can be adjusted according to the specific material (gas or liquid) conveyed by the device.

[0047] When the high-pressure pipe 2 is fixed in the connecting sleeve 1, the circular hole 2 opened on the pressure relief pipe 3 is just aligned with the circular hole 1 opened on the connecting sleeve 1. At this time, one end of the hexagonal wrench (existing tool) is manually passed through the circular hole 1 and the circular hole 2, and inserted into the hole on the screw rod 2 36, and then the hexagonal wrench is rotated to rotate the screw rod 2 36. When the screw rod 2 36 rotates, the adjusting disk 34 is forced to move downward or upward (specifically determined by whether liquid or gas is transported inside the connecting pipe 18, and the pressure of the liquid or gas), and the spring 35 is compressed or stretched, so that the extrusion amount of the spring 35 can be changed. In the process of changing the elastic deformation amount of the spring 35, the resistance force on the upper end of the pressure relief baffle 26 will also change accordingly, that is, when the spring 35 is compressed, the pressure on the upper end of the pressure relief baffle 26 will also increase, and vice versa.

[0048] Reference Fig.11 A retaining ring 38 is fixedly installed in the connecting pipe 18, and the retaining ring 38 is in contact with the lower end of the pressure relief baffle 26 (such as Fig.11 When the spring 35 is compressed, the pressure on the spring 35 will be transmitted to the pressure relief baffle 26. At this time, the baffle ring 38 can effectively prevent the pressure relief baffle 26 from being forced to move downward.

[0049] Reference Fig.12 , Fig.14 , Fig.15 , Fig.16 The pressure relief baffle 26 is provided with a groove (not shown in the figure but not marked). Fig.12 As can be seen in FIG. 1 ), when the pressure inside the connecting pipe 18 is relatively high, the pressure inside the connecting pipe 18 will squeeze the pressure relief baffle 26, causing it to slide upward (such as Figure 8 direction), when the upper end of the tank (such as Figure 8 When the pressure relief baffle 26 is moved out of the connecting pipe 18 in the direction shown in the figure, the liquid or gas inside the connecting pipe 18 will flow out from the gap between the tank body and the connecting pipe 18, thereby achieving pressure relief inside the connecting pipe 18. There is no need to move the pressure relief baffle 26 out of the connecting pipe 18 as a whole, which effectively improves the efficiency of pressure relief inside the connecting pipe 18.

[0050] The purpose of installing the sealing ring 17 and the sealing ring sleeve 16 inside the pressure relief pipe 3 is: when the pressure relief baffle 26 is forced to compress the spring 35 upward, the gas or liquid inside the connecting pipe 18 flows into the pressure relief pipe 3 through the groove body on the pressure relief baffle 26, the sealing ring 17 can effectively improve the sealing performance of the pressure relief pipe 3 to prevent the gas or liquid inside it from flowing out. At the same time, the cooperation between the sealing ring 17 and the sealing ring sleeve 16 can effectively improve the sealing performance of the pressure pipe 2 in the process of inputting gas or liquid into the connecting pipe 18.

[0051] Reference Fig.16 A limit rod 37 is fixedly installed between the adjusting disk 34 and the pressure relief baffle 26, and the limit rod 37 is located inside the spring 35. When the spring 35 is stretched or compressed, the limit rod 37 will also be stretched or compressed. At this time, the deformation of the spring 35 can be limited by the limit rod 37, which can effectively prevent the spring 35 from being damaged or failing due to excessive compression or stretching.

[0052] Reference Figure 6-Figure 8 , Figure 10-Figure 14 A screw rod 29 is fixedly installed on the connecting sleeve 1, a nut 31 is threadedly installed on the screw rod 29, a rotating sleeve 28 is fixedly installed on the nut 31, a connecting ring 30 is rotatably installed on the rotating sleeve 28, a connecting piece (drawn in the figure but not marked) is fixedly installed on the connecting ring 30, and a sealing rubber column 15 is fixedly installed on the connecting piece. After the spacing between the adjusting disk 34 and the pressure relief baffle 26 is adjusted, the nut 31 can be sleeved on the screw rod 29 first, and the sealing rubber column 15 is aligned with the circular hole 1, and then the nut 31 is rotated, so that the nut 31 rotates downward and drives the sealing rubber column 15 to move downward and insert into the circular hole 1 and the circular hole 2, so as to achieve the blocking of the circular hole 2, and prevent the gas or liquid from overflowing from the circular hole 2 when gas or liquid enters the pressure relief pipe 3.

[0053] Reference Figure 8 , Fig.10 , a plurality of circular holes (drawn in the figure but not marked) are provided on the connecting pipe 6, and a one-way tube (not drawn in the figure) is fixedly installed on each of the plurality of circular holes. When the gas or liquid inside the connecting pipe 18 flows into the pressure relief pipe 3, and the gas or liquid inside the pressure relief pipe 3 increases continuously, the liquid or gas will enter the connecting pipe 6 along the plurality of one-way tubes, and finally flow out of the connecting pipe 6. In addition, the flow direction of the liquid or gas can be restricted by the plurality of one-way tubes, that is, the liquid or gas inside the pressure relief pipe 3 can enter the connecting pipe 6 along the one-way tube, but the liquid or gas in the connecting pipe 6 will not flow out of the one-way tube.

[0054] Reference Figure 8-Figure 12 , Fig.14, a rack 25 is fixedly mounted on the pressure relief baffle 26, two vertical plates (drawn in the figure but not marked) are fixedly mounted on the connecting pipe 18, a gear cylinder 24 meshing with the rack 25 is rotatably mounted between the two vertical plates, a sliding groove is provided on the pressure relief pipe 3, a sliding block is slidably mounted on the sliding groove, a rack 23 is fixedly mounted on the lower end of the sliding block, and the rack 23 is meshed with the gear cylinder 24, a connecting rod (drawn in the figure but not marked) is fixedly mounted on the rack 23, and a push piece 21 is fixedly mounted on the connecting rod; The port shape of the sliding groove is set to be a trapezoid, and the port shape of the sliding block near one end of the sliding groove is also a trapezoid. When the rack 23 moves under force, the cooperation between the sliding groove and the sliding block can realize the movement limit of the rack 23 and improve the stability of the rack 23 moving in the horizontal direction, that is, effectively improve the stability of the rack 23 pushing the push member 21 to move in the horizontal direction under force.

[0055] Reference Figure 8-Figure 12 , Fig.17 , Fig.18 , a plurality of slide plates 19 are sealed and slidably installed on the connecting pipe 18, a plurality of movable grooves (drawn in the figure but not marked) are provided on the pressure relief pipe 3, and sliders 20 are slidably installed on the plurality of movable grooves, and round rods (drawn in the figure but not marked) are fixedly installed on the plurality of slide plates 19, and a round roller 1 is fixedly installed between the corresponding two fixed frames 2, and two sliding grooves (drawn in the figure but not marked) are provided on the plurality of slide plates 19, and a fixed frame 1 (drawn in the figure but not marked) is slidably installed on the plurality of sliding grooves, and elastic telescopic rods 27 are fixedly installed between the plurality of fixed frames 1 and the corresponding fixed frames 2, and round rollers 2 are fixedly installed between the corresponding two fixed frames 1, and rotating rods 22 are rotatably installed between the plurality of round rods and the corresponding round rollers 1 and 2.

[0056] When the pressure inside the connecting pipe 18 is high, the pressure relief baffle 26 moves upward (such as Figure 8 In the direction shown), at this time, through the cooperation of the rack 25, the gear cylinder 24, and the rack 1 23, the pusher 21 can be forced to move to the left to push the multiple fixed frames 1 to move (such as Fig. 9 In the direction shown), during the movement of the multiple fixed frames 1, through the cooperation of the corresponding round stick 2, the two rotating rods 22, the round rod, and the slider 20, the multiple slides 19 can be forced to move toward the inside of the connecting pipe 18, that is, the water pressure of the gas or liquid in the connecting pipe 18 passing through the multiple slides 19 to the inside of the connecting pipe 6 is effectively increased.

[0057] When the multiple slides 19 are forced to move closer to each other, the multiple fixing frames 1 will also move closer to each other. When the multiple slides 19 contact each other, the pusher 21 is still in contact with the multiple fixing frames 1, thereby ensuring that the positions of the multiple slides 19 are limited.

[0058] For example, when the pressure inside the connecting pipe 18 is greater than 1 (here 1 is an assumed value for ease of understanding), the pressure relief baffle 26 moves upward under the action of the pressure (such as Figure 8 In the direction shown in the figure), the pressure inside the connecting pipe 18 is relieved. When the pressure inside the connecting pipe 18 is restored to 1, the pressure relief baffle 26 will move downward under the action of gravity to re-block the upper end of the connecting pipe 18 (as shown in the figure). Figure 8 In the direction shown), at this time, the pressure of the connecting pipe 18 flowing into the connecting pipe 6 is 1, but because the pressure of the liquid or gas flowing into the pressure relief pipe 3 is less than 1, and the liquid or gas inside the pressure relief pipe 3 will eventually flow into the connecting pipe 6 through the one-way pipe and mix with the liquid or gas inside the connecting pipe 6, the pressure of the liquid or gas inside the connecting pipe 6 will be less than 1; Therefore, when the pressure relief baffle 26 is forced to move upward (such as Fig. 9 As shown in the direction, the plurality of slide plates 19 will be brought closer to each other, increasing the flow rate of the liquid or gas flowing from the connecting pipe 18 to the inside of the connecting pipe 6, that is, pressurizing the flow rate of the liquid or gas, so that the pressure of the liquid or gas inside the connecting pipe 6 is restored to 1, and when the pressure inside the connecting pipe 18 is restored to stability and the pressure relief baffle 26 is moved down to reset, the pusher 21 will also move to the right to reset (as shown in the direction shown in the direction). Fig. 9 In the direction shown in FIG. 1 ), at this time, the plurality of fixing frames will move to the right side and reset under the elastic potential energy of the corresponding elastic telescopic rod 27 itself (such as Fig. 9 When the plurality of fixing frames are moved to the right side to reset, the plurality of slide plates 19 are moved away from each other and reset through the cooperation of the corresponding rotating rod 22, the round rod and the slider 20.

[0059] The specific working principle of the device includes fixing the high-pressure pipe 2, releasing pressure and stabilizing pressure.

[0060] Fix the high-pressure pipe 2: First, insert the high-pressure pipe 2 into the connecting sleeve 1, so that the high-pressure pipe 2 passes through the fixed plate 10 and the sealing ring sleeve 16 and abuts against the sealing ring 17, and then rotate the threaded sleeve 5 so that the multiple connecting rods 4 drive the pressure relief pipe 3 to slide in the connecting sleeve 1. At the same time, when the pressure relief pipe 3 moves to the left in the connecting sleeve 1 (such as Figure 3In the direction shown), the fixed plate 10 will be driven to move together through multiple rods, and during the movement of the fixed plate 10, the multiple slide bars 9 will first squeeze the corresponding conical springs 11. When the multiple conical springs 11 are squeezed and deformed to a certain extent, the slide bar 9 continues to move, and the multiple push rods 8, multiple stop blocks 12 and multiple clamps 13 will be driven to move to the left together through the multiple conical springs 11. At this time, under the limiting effect of the multiple limit blocks 7 on the corresponding stop blocks 12, the multiple stop blocks 12 will move along the side inclination of the corresponding limit blocks 7, driving the corresponding clamps 13 to move to the side close to the high-pressure pipe 2, so as to achieve the clamping and fixation of the high-pressure pipe 2 (the present device utilizes the high-pressure pipe 2 to connect to the high-pressure equipment, and is connected to the delivery pipeline of the high-pressure gas or high-pressure liquid, such as a high-pressure water gun, a high-pressure air gun, etc., and is connected to the valve, equipment, other pipeline systems, etc. with the connecting pipe 6).

[0061] When the high-pressure pipe 2 is fixed, and the multiple conical springs 11 are still elastic, it is necessary to continue to rotate the threaded sleeve 5 so that the pressure relief pipe 3 continues to drive the sliding rod 9 to move through the fixed plate 10 until the multiple conical springs 11 are compressed to the maximum compression it can withstand, that is, when they can no longer be compressed, stop rotating the threaded sleeve 5. At this time, the multiple conical springs 11 do not have a compression function. Through the cooperation of the fixed plate 10, the multiple sliding rods 9, the multiple conical springs 11 and the multiple blocks 12, the multiple clamps 13 can be locked to prevent the multiple clamps 13 from rebounding, which can effectively enhance the effect of the multiple clamps 13 on clamping and fixing the high-pressure pipe 2.

[0062] Pressure relief: When the pressure in the high-pressure pipe 2 and the connecting pipe 18 increases, the pressure relief baffle 26 is pushed upward (such as Figure 8 When the pressure relief baffle 26 is turned in the direction shown in the figure, part of the liquid or gas in the connecting pipe 18 will flow into the pressure relief pipe 3 through the groove body provided on the pressure relief baffle 26, so as to realize the pressure relief of the connecting pipe 18, and the liquid or gas in the pressure relief pipe 3 will eventually enter the connecting pipe 6 through the one-way pipe on the connecting pipe 6 (the distance between the disk 34 and the pressure relief baffle 26 can be adjusted by rotating the screw 36 in advance to move the screw 36 on the nut 33, that is, changing the elastic force of the spring 35, so as to realize the limit pressure value of the upper end of the pressure relief baffle 26 according to the pressure value in the connecting pipe 18), and mix with the gas or liquid flowing out of the connecting pipe 18 (at this time, the pressure of the gas or liquid inside the connecting pipe 6 is less than the pressure inside the connecting pipe 18).

[0063] Stable pressure: When the pressure relief baffle 26 is forced to move upward (such as Figure 8 In the process of the rack 25 moving upward, the push member 21 will push the plurality of fixed frames 1 (such as Fig. 9As shown in the direction, when the multiple fixing frames are forced to move to the left, the multiple rotating rods 22 on the right side are forced to rotate (such as Figure 8 As shown in the direction), push the corresponding slider 20 to slide to the left on the pressure relief pipe 3 (as shown in the direction of Fig. 9 As shown in the direction, when the multiple sliders 20 are forced to slide to the left, the multiple rotating rods 22 on the left are forced to rotate, so that the multiple slide plates 19 are forced to approach each other. In the process of the multiple slide plates 19 constantly approaching each other, the gas or liquid inside the connecting pipe 18 passes through the middle position of the multiple slide plates 19, and the speed toward the connecting pipe 6 will also increase accordingly, thereby achieving an increase in the internal pressure of the connecting pipe 6.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
