Description

Technical Field

[0001] This utility model belongs to the field of car wash machine technology, specifically relating to a quick-connect pipe device for a car wash machine. Background Technology

[0002] Car wash machines primarily utilize computer-controlled brushes and high-pressure water to automatically clean cars. During operation, they need to be connected to external water pipes. A search reveals that application number "CN202323371363.X" discloses a "quick-connect fitting for water pipes," which describes a method that "seals the connection between the water pipe and the support sleeve. Furthermore, a locking function design locks the clamping force of the clamping component on the water pipe, preventing loosening after the connection. Therefore, the device in this application ensures a stable connection between the water pipe and the support sleeve." While this method effectively seals the connection and locks the clamping force, the device in this application does have the following drawbacks in practical use:

[0003] In actual use, when the water pipe needs to be pulled out after use, it cannot be sealed quickly, resulting in continuous water flow when the water pipe is pulled out, wasting water resources. It is necessary to close the water valve or connect other valves, which is inefficient. In addition, the need for threaded connection during use also leads to poor work efficiency.

[0004] Therefore, providing a device that can achieve leak-proof pull-out and quick connection is of great practical value. Utility Model Content

[0005] The purpose of this invention is to provide a quick-connect pipe device for car wash machines, which aims to solve the above-mentioned technical problems.

[0006] This utility model provides a quick-connect pipe device for a car wash machine, including a connecting pipe, a plug-in leak-proof component, and a quick-connect component.

[0007] The connecting pipe has a sealed connection to a positioning seat on one side, and a male connector has a sealed connection to a male connector on one side. The outer wall of the male connector has several slots.

[0008] The plug-in leak-proof assembly includes a connector disposed inside the male connector. The inner wall of the connector is provided with two fixing rods. A limit rod is provided between the two fixing rods. A conical sealing head is slidably connected to the outer wall of the limit rod. A sealing ring is provided on the outer wall of the conical sealing head. A first spring is provided on one side of the conical sealing head. One side of the first spring is fixedly connected to the two fixing rods. The inside of the first spring is slidably connected to the limit rod.

[0009] The quick-connect assembly includes a protective head that is inserted into the outer wall of the male connector. A fixed tube is sealed and connected to one side of the protective head. Several connecting boxes are provided on the outer wall of the fixed tube. A plug is slidably connected inside the connecting boxes. Movable plates are provided on both sides of the plug. Damping rod springs are provided at the bottom of two of the movable plates. The bottoms of the two damping rod springs are fixedly connected to the bottom of the inner wall of the connecting box. A limit ring is provided on the outer wall of the fixed tube. A second spring is provided on one side of the limit ring. A movable ring is provided on one side of the second spring. A fixed ring is provided on one side of the movable ring.

[0010] In one embodiment of this utility model, the interior of the fixed ring is movably connected to the outer wall of several plugs, and the interiors of the second spring and the movable ring are slidably connected to the fixed tube.

[0011] In one embodiment of this utility model, a guide bucket is provided on one side of the protective head, a female head is provided on one side of the inner wall of the fixing tube, and two reinforcing rods are provided on the inner wall of the female head.

[0012] In one embodiment of this utility model, a tube is provided between the two reinforcing rods, a sealing plug is provided on one side of the female head, and a sealing slot is provided on one side of the male head.

[0013] In one embodiment of this utility model, a first external connector is sealed and connected to one side of the female connector, the outer wall of the first external connector is inserted and connected to the fixing pipe, and a second external connector is sealed and connected to one side of the connecting pipe.

[0014] In one embodiment of this utility model, both sides of the two movable plates are slidably connected to the inner walls of the connecting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) During use, the user holds the connecting tube and inserts the male end into the female end along the guide tube. At this time, the tube will cover the limiting rod. The user continues to insert the tube, which moves on the outer wall of the limiting rod and pushes open the conical sealing head. The conical sealing head slides on the limiting rod, which causes the first spring to contract and store force. After the conical sealing head separates from the connecting head, water can be transmitted to the female end through the connecting head. When the user separates the male end from the female end and pulls it out, the tube will slide off the limiting rod, the force on the conical sealing head will disappear, and the first spring will return to its original position, causing the conical sealing head to cooperate with the sealing ring to block the connecting head and cut off the water flow. This achieves the purpose of inserting to allow water and pulling out to cut off water and prevent leakage.

[0017] 2) During use, the user holds the fixing ring and pulls it to one side, causing the fixing ring to move and the moving ring to contract. At this time, the user holds the connecting pipe and inserts the male end into the female end along the guide tube, so that the sealing slot on the male end connects and seals with the sealing plug on the female end. When the male end is inserted into the female end, the outer wall of the male end contacts the plug. The contact surface between the plug and the male end is arc-shaped, causing the male end to push the plug open. The plug will move towards the outer wall, which will then move the moving plate, causing the second spring to be pulled open. At this time, the male end continues to be inserted. When it is fully inserted, the user can slightly rotate the male end to make the plug contact the slot. The damping rod spring returns to its original position, moving the moving plate and then the plug is inserted into the slot to fix the male end. At this time, the user releases the fixing ring, which returns to its original position through the second spring and is locked onto the plug, limiting the plug and thus limiting the plug to the male end, thereby achieving the purpose of quick pipe connection.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figure 1-5 A quick-connect pipe device for a car wash machine includes a connecting pipe 100, a plug-in leak-proof component 200, and a quick-connect component 300.

[0028] Please refer to the details. Figure 1 One side of the connecting pipe 100 is sealed and connected to the positioning seat 110, and one side of the positioning seat 110 is sealed and connected to the male head 120. The outer wall of the male head 120 is provided with several slots.

[0029] Please see Figure 3-4 The plug-in leak-proof assembly 200 includes a connector 210 disposed inside the male connector 120. The inner wall of the connector 210 is provided with two fixing rods 220. A limit rod 230 is provided between the two fixing rods 220. A conical sealing head 240 is slidably connected to the outer wall of the limit rod 230. A sealing ring 250 is provided on the outer wall of the conical sealing head 240. A first spring 260 is provided on one side of the conical sealing head 240. One side of the first spring 260 is fixedly connected to the two fixing rods 220. The interior of the first spring 260 is slidably connected to the limit rod 230.

[0030] In one specific embodiment, the provided conical sealing head 240 facilitates the user's insertion of the male head 120 onto the female head 500 by holding the connecting tube 100 and guiding it along the guide tube 400. At this time, the insertion tube 700 will cover the limiting rod 230. As the user continues to insert, the insertion tube 700 moves against the outer wall of the limiting rod 230, pushing open the conical sealing head 240. This allows the conical sealing head 240 to slide on the limiting rod 230, thereby causing the first spring 260 to contract and store force. After the conical sealing head 240 is separated from the connector 210, water can be transmitted to the female head 500 through the connector 210. When the user separates the male head 120 from the female head 500 and pulls it out, the insertion tube 700 will slide down from the limit rod 230, the force on the conical sealing head 240 will disappear, and the first spring 260 will reset, causing the conical sealing head 240 to cooperate with the sealing ring 250 to block the connector 210, thereby cutting off the water flow. This achieves the purpose of allowing water to flow when inserted and cutting off water and preventing leakage when pulled out.

[0031] Please see Figure 1-5 The quick-connect assembly 300 includes a protective head 310 that is inserted into the outer wall of the male connector 120. A fixed tube 320 is sealed and connected to one side of the protective head 310. Several connecting boxes 330 are provided on the outer wall of the fixed tube 320. A plug 340 is slidably connected inside the connecting box 330. Movable plates 350 are provided on both sides of the plug 340. Damping rod springs 360 are provided at the bottom of the two movable plates 350. The bottom of the two damping rod springs 360 is fixedly connected to the bottom of the inner wall of the connecting box 330. A limit ring 370 is provided on the outer wall of the fixed tube 320. A second spring 380 is provided on one side of the limit ring 370. A movable ring 390 is provided on one side of the second spring 380. A fixed ring 3910 is provided on one side of the movable ring 390.

[0032] In one specific embodiment, the provided plug 340 allows the user to easily grasp the fixing ring 3910 and pull it to one side, causing the fixing ring 3910 to move the moving ring 390, which in turn causes the second spring 380 to contract. At this time, the user holds the connecting tube 100 and inserts the male head 120 along the guide tube 400 into the female head 500, so that the sealing slot on the male head 120 connects and seals with the sealing plug 800 on the female head 500. When the male head 120 is inserted into the female head 500, the outer wall of the male head 120 contacts the plug 340. The contact surface between the plug 340 and the male head 120 is arc-shaped, allowing the male head 120 to push the plug 340 open. When plug 340 is pushed open, it will move towards the outer wall, which in turn will move the moving plate 350, causing the second spring 380 to be pulled open. At this time, the male connector 120 continues to be inserted. When it is fully inserted, the user can slightly rotate the male connector 120 to make plug 340 contact the slot. This releases the momentary damping rod spring 360, which returns to its original position, causing the moving plate 350 to move and then the plug 340 to be inserted into the slot and fixed to the male connector 120. At this time, the user can loosen the fixing ring 3910, which returns to its original position through the second spring 380 and is locked onto the plug 340, limiting the plug 340. This limits the plug 340 to the male connector 120, thereby achieving the purpose of quick connection.

[0033] Please see Figure 1 The interior of the fixed ring 3910 is movably connected to the outer wall of several plugs 340, and the interiors of the second spring 380 and the movable ring 390 are slidably connected to the fixed tube 320.

[0034] In one specific embodiment, the fixed tube 320 facilitates the limiting of the movement of the second spring 380 and the moving ring 390, making them more stable during movement and avoiding swaying.

[0035] Please see Figure 3 A guide bucket 400 is provided on one side of the protective head 310, and a female head 500 is provided on one side of the inner wall of the fixing tube 320. Two reinforcing rods 600 are provided on the inner wall of the female head 500.

[0036] In one specific embodiment, the guide bucket 400 facilitates the user's quick insertion of the male head 120 into the female head 500, improving work efficiency and increasing convenience.

[0037] Please see Figure 3 A tube 700 is provided between the two reinforcing rods 600, a sealing plug 800 is provided on one side of the female head 500, and a sealing slot is provided on one side of the male head 120.

[0038] In one specific embodiment, the provided sealing plug 800 facilitates its engagement with the sealing slot during use, thereby sealing the male connector 120 and the female connector 500 together to prevent leakage and improve stability.

[0039] Please see Figure 3 The female connector 500 has a first external connector 900 sealed and connected to one side. The outer wall of the first external connector 900 is inserted and connected to the fixed tube 320. The connecting tube 100 has a second external connector 1000 sealed and connected to one side.

[0040] In one specific embodiment, the first external connector 900 facilitates connection to an external water pipe during use, while the second external connector 1000 facilitates connection to various car wash devices during use.

[0041] Please see Figure 5 Both sides of the two movable plates 350 are slidably connected to the inner walls of the connecting box 330.

[0042] In one specific embodiment, the movable plate 350 allows for easy sliding within the connecting box 330 during use, thereby limiting the stability of the connecting box 330 and preventing shaking during use.

[0043] In use, the conical sealing head 240 allows the user to easily insert the male head 120 into the female head 500 by holding the connecting pipe 100 and guiding it along the guide bucket 400. At this time, the insertion pipe 700 will cover the limiting rod 230. As the user continues to insert, the insertion pipe 700 moves against the outer wall of the limiting rod 230, pushing open the conical sealing head 240. This allows the conical sealing head 240 to slide on the limiting rod 230, causing the first spring 260 to contract and store force. After the conical sealing head 240 separates from the connecting head 210, water can flow through the connecting head. 210 transmits to the female connector 500. When the user separates the male connector 120 from the female connector 500, the insertion tube 700 slides off the limiting rod 230, the force on the conical sealing head 240 disappears, causing the first spring 260 to reset and drive the conical sealing head 240 to cooperate with the sealing ring 250 to block the connector 210, thus cutting off the water flow. This achieves the purpose of allowing water to flow when inserted and cutting off water and preventing leakage when pulled out. Then, through the provided plug 340, it is convenient for the user to hold the fixing ring 3910 and pull it to one side, so that the fixing ring 3910 drives the moving ring. The movement of 390 causes the second spring 380 to contract under force. At this time, the user holds the connecting tube 100 and inserts the male head 120 into the female head 500 along the guide bucket 400, so that the sealing slot on the male head 120 connects and seals with the sealing plug 800 on the female head 500. When the male head 120 is inserted into the female head 500, the outer wall of the male head 120 contacts the plug 340. The contact surface between the plug 340 and the male head 120 is arc-shaped, so the male head 120 pushes the plug 340 open. The plug 340, being pushed open, will move towards the outer wall, thereby driving the moving plate 350 to move, so that the second spring 380 contracts under force. The second spring 380 is pulled open by force, at which point the male connector 120 continues to be inserted. When fully inserted, the user can slightly rotate the male connector 120 to make the plug 340 contact the slot, releasing the momentary damping rod spring 360 to reset, driving the moving plate 350 to move and then driving the plug 340 to insert into the slot and fix the male connector 120. At this time, the user loosens the fixing ring 3910, allowing it to reset through the second spring 380 and lock onto the plug 340, limiting the plug 340, and thus limiting the plug 340 to the male connector 120, thereby achieving the purpose of quick connection.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
