Abstract
Description
Technical Field
[0001] This utility model relates to the field of coolant reservoirs, and more particularly to a quick connector. Background Technology
[0002] With the development of the automotive industry, the cooling system, as an important guarantee for the normal operation of the car engine, directly affects the reliability and life of the engine. The coolant reservoir, as an important part of the cooling system, is responsible for storing and replenishing coolant, while the quick connector plays a key role in sealing and pressure balancing.
[0003] A search revealed Chinese patent publication number CN219570190U, which discloses a coolant reservoir and an automobile. The reservoir includes a body with a slot at its bottom containing an elastic buffer pad. The buffer pad has a positioning groove for inserting a connector. This application aims to reduce noise between the reservoir body and the connecting arm during vehicle vibrations. However, in actual use, the contact area between the reservoir body and the reservoir opening is prone to wear under frequent vibrations and impacts. With increased usage time, the sealing gap widens, increasing the probability of coolant leakage. This not only wastes coolant but can also cause engine overheating due to insufficient coolant, affecting the vehicle's normal operation and lifespan. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a quick connector, which aims to improve the problem in the prior art where the contact part with the spout is prone to wear under frequent vibration and impact, leading to increased replacement costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick connector, comprising an irregularly shaped kettle lid, wherein L-shaped connecting tubes are provided on both the left and right sides of the inner wall of the irregularly shaped kettle lid, a conical hollow block is provided at the bottom of the outer wall of the L-shaped connecting tube, a plurality of compression springs are fixedly connected to the top of the conical hollow block, a hollow extrusion block is fixedly connected to the top of each of the plurality of compression springs, a sealing ring is fixedly connected to the top of the hollow extrusion block, hollow threaded columns are fixedly connected to both the left and right sides of the top of the irregularly shaped kettle lid, a plurality of notches are provided at the top of the hollow threaded columns, a hollow extrusion cap is threadedly connected to the outer wall of the hollow threaded columns, a plurality of mounting hollow blocks are fixedly connected to the outer wall of the irregularly shaped kettle lid, a fastening screw is threadedly connected to the right side of the outer wall of the conical hollow block, and an automatic venting mechanism is provided in the middle of the inner wall of the irregularly shaped kettle lid.
[0006] Through the above technical solution: the L-shaped connecting pipes on the left and right sides of the inner wall of the irregular-shaped cap connect to the internal pipes of the coolant reservoir. The conical hollow block at the bottom of the outer wall of the L-shaped connecting pipe fits tightly with the corresponding interface of the coolant reservoir. The conical hollow block is firmly fixed by the fastening screw on the right side of the outer wall of the conical hollow block through threaded connection. In terms of sealing, multiple compression springs at the top of the conical hollow block are in a compressed state, generating an upward elastic force on the hollow extrusion block, so that the sealing ring at the top of the hollow extrusion block fits tightly against the inner wall of the coolant reservoir, forming a good sealing effect and preventing coolant leakage. At the same time, the cooperation between the hollow threaded column and the hollow extrusion cap enhances the sealing performance and structural stability. The notch at the top of the hollow threaded column facilitates the extrusion clamping of the L-shaped connecting pipe when the hollow extrusion cap is threaded, thereby fixing the L-shaped connecting pipe. The hollow block is used to fix the cap to the coolant reservoir or other components, thereby allowing for quick disassembly and replacement of worn L-shaped connecting pipes.
[0007] As a further description of the above technical solution:
[0008] The automatic exhaust mechanism includes an exhaust pipe. The upper part of the outer wall of the exhaust pipe is fixedly connected to the middle part of the inner wall of the irregularly shaped lid. A sliding partition is slidably connected to the bottom end of the inner wall of the exhaust pipe. A float is fixedly connected to the bottom end of the sliding partition. Multiple connecting holes are opened in the middle of the outer wall of the exhaust pipe. Conical limiting blocks are fixedly connected to the upper and lower sides of the inner wall of the exhaust pipe. A sliding partition is provided on an adjacent side of two conical limiting blocks. The outer wall of the sliding partition is slidably connected to the inner wall of the exhaust pipe.
[0009] The above technical solution works as follows: When the coolant in the reservoir experiences a pressure imbalance, the sliding baffle is disrupted. The baffle is then pushed upwards by the high pressure inside the reservoir and restricted by a conical stop block, preventing it from moving too far. The high-pressure gas inside the reservoir then escapes through the gap between the sliding baffle and the exhaust pipe until the pressure inside the reservoir equalizes with the external pressure. At this point, the sliding baffle slides down under its own weight, sealing the exhaust pipe and preventing external dust from entering the reservoir. If the coolant boils and sprays upwards, the float is pushed upwards by the coolant above, causing the sliding baffle to rise and block the connecting hole above the exhaust pipe, preventing the boiling coolant from flowing out through the exhaust pipe and thus ensuring stable pressure inside the reservoir.
[0010] As a further description of the above technical solution:
[0011] The inner wall of the irregularly shaped lid is fixedly connected to the left and right sides of the top, and the two adjacent sides of the sealing rings are fixedly connected to the front and rear ends of the sealing rings.
[0012] Through the above technical solution: the sealing ring can fill the tiny gap between the lid and the mouth of the vessel by its own elastic deformation, forming the first physical sealing barrier to ensure that the coolant will not leak during storage and pressure changes. The connecting strip can deform in tandem with the sealing ring when it is under force, maintaining the stability of the overall sealing structure.
[0013] As a further description of the above technical solution:
[0014] The bottom of the outer wall of the L-shaped connecting tube is fixedly connected with multiple limiting strips, and the inner wall of the conical hollow block is provided with multiple grooves, and the outer wall of each limiting strip engages with the inner wall of the groove.
[0015] Through the above technical solution: when the L-shaped connecting pipe and the conical hollow block are assembled, the limiting strip can cooperate with the groove on the inner wall of the conical hollow block to restrict the axial movement of the L-shaped connecting pipe, ensure that the L-shaped connecting pipe and the conical hollow block are accurately positioned and firmly connected, and prevent the connection from loosening due to vibration during the flow of coolant, which would affect the normal transmission of coolant.
[0016] As a further description of the above technical solution:
[0017] The front side of the outer wall of the L-shaped connecting pipe is connected to a partition pipe, and multiple anti-slip sleeves are fixedly connected to the outer wall of the partition pipe.
[0018] Through the above technical solutions: the diaphragm can limit the position of the pipe connected to the outside world, and the anti-slip sleeve can increase the sealing capacity of the pipe connected to the outside world.
[0019] As a further description of the above technical solution:
[0020] The top of the exhaust pipe is threaded with a hollow screw, and the outer wall of the hollow screw has multiple vent holes.
[0021] Through the above technical solution, the hollow screw can be quickly rotated downwards when the exhaust pipe needs to be inspected or cleaned, preventing coolant from leaking from the top, and the air pressure inside and outside the cooling system can be balanced through the vent hole.
[0022] As a further description of the above technical solution:
[0023] The inner wall dimension of the hollow extrusion cap is smaller than the outer wall dimension of the hollow threaded column, and the inner wall dimension of the hollow extrusion cap is the same as the outer wall dimension of the L-shaped connecting pipe.
[0024] Through the above technical solution: the inner wall size of the hollow extrusion cap is smaller than the outer wall size of the hollow threaded column, which allows the two to be tightly connected, preventing relative displacement between the hollow extrusion cap and the hollow threaded column under the impact and vibration generated by the flow of coolant, thus enhancing the sealing and structural stability of the connection. By making the inner wall size of the hollow extrusion cap consistent with the outer wall size of the L-shaped connecting pipe, the hollow extrusion cap can be precisely fitted onto the L-shaped connecting pipe to form a seamless connection, while also ensuring the smooth flow of coolant between various components.
[0025] As a further description of the above technical solution:
[0026] The inner wall of the exhaust pipe has multiple annular gaps, and the inner wall of the exhaust pipe is rounded.
[0027] Through the above technical solution: the annular gap can increase the turbulence effect of the coolant when it flows in the exhaust pipe, so that the coolant can fully contact the inner wall of the exhaust pipe and improve the heat dissipation efficiency. By making the inner wall of the exhaust pipe smooth, the coolant can pass through the exhaust pipe more smoothly and reduce energy loss.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the L-shaped connecting pipe is connected to the coolant reservoir pipe, the conical hollow block fits tightly with the reservoir interface and is fixed by fastening screws, the compression spring ensures that the sealing ring is tightly attached to the inner wall of the reservoir to prevent leakage, the cooperation between the hollow threaded column and the extrusion cap improves the sealing and stability, the notch facilitates the fixed installation of the L-shaped connecting pipe, and the hollow block is used to fix the reservoir cap and the coolant reservoir, thereby facilitating the quick replacement of the L-shaped connecting pipe.
[0030] 2. In this utility model, the sliding partition is pushed upward by high pressure and restricted by the conical limiting block. The gas is discharged through the gap between the sliding partition and the exhaust pipe until the internal and external air pressure is balanced. Then, the sliding partition slides down due to gravity, sealing the exhaust pipe and preventing dust from entering. If the coolant in the pot boils, the float ball and the sliding partition rise, blocking the connecting hole and preventing the coolant from overflowing through the exhaust pipe, thereby ensuring the stability of the air pressure in the pot.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a quick connector, including a shaped lid 1. L-shaped connecting pipes 3 are provided on both the left and right sides of the inner wall of the lid 1. The L-shaped connecting pipes 3 on the left and right sides of the inner wall of the lid 1 connect to the internal pipes of the coolant reservoir. A conical hollow block 4 is provided at the bottom of the outer wall of the L-shaped connecting pipe 3. The conical hollow block 4 fits tightly with the corresponding interface of the coolant reservoir. Multiple compression springs 5 are fixedly connected to the top of the conical hollow block 4. A hollow extrusion block 6 is fixedly connected to the top of each compression spring 5. A sealing ring 7 is fixedly connected to the top of the hollow extrusion block 6. The multiple compression springs 5 at the top of the conical hollow block 4 are in a compressed state, generating an upward elastic force on the hollow extrusion block 6, causing the hollow extrusion block... The sealing ring 7 at the top of the 6 tightly fits the inner wall of the coolant reservoir, forming a good sealing effect. Hollow threaded columns 8 are fixedly connected to the left and right sides of the top of the shaped reservoir lid 1. Multiple notches 9 are opened at the top of the hollow threaded column 8. The notches 9 at the top of the hollow threaded column 8 are to facilitate the hollow threaded column 8 to squeeze and clamp the L-shaped connecting tube 3 when the hollow extrusion cap 10 is threaded. The hollow extrusion cap 10 is threadedly connected to the outer wall of the hollow threaded column 8. Multiple hollow mounting blocks 11 are fixedly connected to the outer wall of the shaped reservoir lid 1. The fastening screw 12 is threadedly connected to the right side of the outer wall of the conical hollow block 4. The fastening screw 12 fixes the position of the conical hollow block 4. An automatic venting mechanism 2 is provided in the middle of the inner wall of the shaped reservoir lid 1.
[0041] Specifically, the L-shaped connecting pipes 3 on the left and right sides of the inner wall of the shaped coolant cap 1 connect to the internal pipes of the coolant reservoir. The conical hollow block 4 at the bottom of the outer wall of the L-shaped connecting pipe 3 fits tightly with the corresponding interface of the coolant reservoir. The conical hollow block 4 is firmly fixed by the fastening screw 12 on the right side of the outer wall of the conical hollow block 4 through threaded connection. In terms of sealing, the multiple compression springs 5 at the top of the conical hollow block 4 are in a compressed state, generating an upward elastic force on the hollow extrusion block 6, so that the sealing ring 7 at the top of the hollow extrusion block 6 fits tightly against the inner wall of the coolant reservoir, forming a good sealing effect and preventing coolant leakage. At the same time, the cooperation between the hollow threaded column 8 and the hollow extrusion cap 10 enhances the sealing performance and structural stability. The notch 9 at the top of the hollow threaded column 8 is to facilitate the extrusion clamping of the L-shaped connecting tube 3 by the hollow extrusion cap 10 during threaded connection, thereby fixing the L-shaped connecting tube 3 in place. The hollow block 11 is used to fix the cap to the coolant reservoir or other components, thereby allowing for quick disassembly and replacement of the worn L-shaped connecting tube 3.
[0042] Reference Figure 2 , Figure 3 and Figure 6The automatic venting mechanism 2 includes an vent pipe 201. The upper part of the outer wall of the vent pipe 201 is fixedly connected to the middle part of the inner wall of the irregularly shaped lid 1. A sliding partition 203 is slidably connected to the bottom end of the inner wall of the vent pipe 201. A float 204 is fixedly connected to the bottom end of the sliding partition 203. When the coolant in the pot boils and sprays upwards, the float 204 is pushed upwards by the coolant above, causing the sliding partition 203 to rise and block the connecting hole 202 above the vent pipe 201. Multiple connecting holes 202 are opened in the middle part of the outer wall of the vent pipe 201. The upper and lower sides of the inner wall of the vent pipe 201 Each is fixedly connected with a conical limiting block 205. A sliding partition 206 is provided on the adjacent side of the two conical limiting blocks 205. The outer wall of the sliding partition 206 is slidably connected to the inner wall of the exhaust pipe 201. The sliding partition 206 is pushed to the top by the high pressure inside the pot and is restricted by the conical limiting block 205 so that it cannot move too much. At this time, the high pressure gas inside the pot will be discharged through the gap between the sliding partition 206 and the exhaust pipe 201 until the gas pressure inside the pot is equal to the gas pressure outside. At this time, under the action of its own gravity, the sliding partition 206 slides down, thereby sealing the exhaust pipe 201.
[0043] Specifically, when the coolant pressure in the coolant reservoir becomes unbalanced, it disrupts the balance of the sliding baffle 206. The sliding baffle 206 is then pushed upwards by the high pressure inside the reservoir and restricted by the conical limit block 205, preventing it from moving too far. Meanwhile, the high-pressure gas inside the reservoir is discharged through the gap between the sliding baffle 206 and the exhaust pipe 201 until the pressure inside the reservoir equalizes with the external pressure. At this point, the sliding baffle 206 slides down under its own weight, sealing the exhaust pipe 201 and preventing external dust from entering the reservoir. If the coolant in the reservoir boils and sprays upwards, the float 204 is pushed upwards by the coolant above, causing the sliding baffle 203 to rise and block the connecting hole 202 above the exhaust pipe 201, preventing the boiling coolant from flowing out through the exhaust pipe and thus ensuring stable pressure inside the reservoir.
[0044] Reference Figure 3 , Figure 4 and Figure 5The inner top of the irregularly shaped lid 1 is fixedly connected to both the left and right sides with sealing rings 13. The sealing rings 13 can fill the tiny gap between the lid and the mouth of the pot by their own elastic deformation. The front and rear ends of the two adjacent sides of the sealing rings 13 are fixedly connected to the connecting strips 14. The connecting strips 14 can deform together with the sealing rings 13 when they are subjected to force to maintain the stability of the overall sealing structure. The bottom of the outer wall of the L-shaped connecting tube 3 is fixedly connected to multiple limiting strips 15. The limiting strips 15 can ensure that the L-shaped connecting tube 3 and the conical hollow block are in contact. 4. Precise positioning and firm connection: The inner wall of the conical hollow block 4 has multiple grooves 16, and the outer wall of the limiting strip 15 is engaged with the inner wall of the groove 16. The grooves 16 can strengthen the connection between the L-shaped connecting pipe 3 and the conical hollow block 4. The front side of the outer wall of the L-shaped connecting pipe 3 is connected to the partition pipe 17. The partition pipe 17 can limit the position of the pipe connected to the outside. The outer wall of the partition pipe 17 is fixedly connected with multiple anti-slip sleeves 18. The anti-slip sleeves 18 can increase the sealing capacity of the pipe connected to the outside.
[0045] Specifically, the sealing ring 13 can elastically deform to fill the tiny gap between the lid and the spout, forming the first physical sealing barrier to prevent coolant from overflowing from the top edge of the lid, ensuring no leakage of coolant during storage and pressure changes. The connecting strip 14 can deform in tandem with the sealing ring 13 under stress, maintaining the stability of the overall sealing structure. The limiting strip 15, when the L-shaped connecting pipe 3 is assembled with the conical hollow block 4, engages with the groove 16 on the inner wall of the conical hollow block 4, restricting the axial movement of the L-shaped connecting pipe 3 and ensuring... The L-shaped connecting pipe 3 and the conical hollow block 4 are precisely positioned and firmly connected to prevent the connection from loosening due to vibration during coolant flow, which would affect the normal transmission of coolant. The groove 16 can strengthen the connection strength between the L-shaped connecting pipe 3 and the conical hollow block 4, ensuring that no gaps will appear at the connection point when the coolant circulation system pressure fluctuates, thus preventing coolant leakage. It also facilitates quick disassembly and installation during maintenance. The partition pipe 17 can limit the position of the pipe connected to the outside, and the anti-slip sleeve 18 can increase the sealing capacity of the pipe connected to the outside.
[0046] Reference Figure 3 , Figure 5 and Figure 6The exhaust pipe 201 has a hollow screw 19 threaded at its top. When the exhaust pipe 201 needs to be inspected or cleaned, the hollow screw 19 can be quickly rotated downwards to prevent coolant leakage from the top. The outer wall of the hollow screw 19 has multiple vent holes 20, which can balance the air pressure inside and outside the cooling system. The inner wall size of the hollow extrusion cap 10 is smaller than the outer wall size of the hollow threaded column 8, which allows the two to be tightly connected, enhancing the sealing and structural stability of the connection. The inner wall size of the hollow extrusion cap 10 is the same as the outer wall size of the L-shaped connecting pipe 3, which allows the hollow extrusion cap 10 to be precisely fitted onto the L-shaped connecting pipe 3 to form a seamless connection. The inner wall of the exhaust pipe 201 has multiple annular gaps 21, which can increase the turbulence effect when the coolant flows in the exhaust pipe 201. The inner wall of the exhaust pipe 201 is rounded, which allows the coolant to pass through the exhaust pipe 201 more smoothly and reduces energy loss.
[0047] Specifically, the hollow screw 19 allows for quick unscrewing when the exhaust pipe 201 needs maintenance or cleaning, preventing coolant leakage from the top. The vent hole 20 balances the air pressure inside and outside the cooling system. The inner wall dimension of the hollow extrusion cap 10 is smaller than the outer wall dimension of the hollow threaded column 8, ensuring a tight connection and preventing relative displacement between the hollow extrusion cap 10 and the hollow threaded column 8 under the impact and vibration of coolant flow, thus enhancing the sealing and structural stability of the connection. Furthermore, the inner wall dimension of the hollow extrusion cap 10 matches the outer wall dimension of the L-shaped connecting pipe 3, allowing for… The hollow extrusion cap 10 can be precisely fitted onto the L-shaped connecting pipe 3 to form a seamless connection. This not only ensures the compactness of the overall structure, but also evenly transmits the force to the L-shaped connecting pipe 3 when the hollow extrusion cap 10 is subjected to external force, avoiding excessive local stress. It also ensures the smooth flow of coolant between various components. The annular gap 21 can increase the turbulence effect of coolant flowing in the exhaust pipe 201, allowing the coolant to fully contact the inner wall of the exhaust pipe 201 and improving heat dissipation efficiency. The rounded inner wall of the exhaust pipe 201 allows the coolant to pass through the exhaust pipe 201 more smoothly, reducing energy loss.
[0048] Working principle: First, L-shaped connecting pipes 3 are provided on the left and right sides of the inner wall of the irregularly shaped cap 1. These connecting pipes are connected to the internal pipes of the coolant reservoir. A conical hollow block 4 is provided at the bottom of the outer wall of the L-shaped connecting pipe 3. This hollow block fits tightly with the corresponding interface of the coolant reservoir and is fixed by a threaded connection. The fastening screw 12 on the right side of the outer wall of the conical hollow block 4 ensures its firmness. In terms of sealing, multiple compression springs 5 at the top of the conical hollow block 4 are in a compressed state, applying an upward elastic force to the hollow extrusion block 6, so that the sealing ring 7 at the top of the hollow extrusion block 6 fits tightly against the inner wall of the coolant reservoir, thereby forming an effective sealing effect and preventing coolant leakage. In addition, the cooperation between the hollow threaded column 8 and the hollow extrusion cap 10 further enhances the sealing performance and structural stability. The notch 9 at the top of the hollow threaded column 8 facilitates the compression and clamping of the L-shaped connecting pipe 3 when the hollow extrusion cap 10 is threaded, so as to fix the L-shaped connecting pipe 3. The hollow block 11 is used to... The lid is fixedly installed with the coolant reservoir or other components, facilitating quick disassembly and replacement of the easily worn L-shaped connecting pipe 3. Furthermore, through the automatic venting mechanism 2, when the coolant pressure in the container becomes unbalanced, it disrupts the equilibrium of the sliding baffle 206. At this time, the sliding baffle 206 moves upward under the pressure of the container, constrained by the conical limit block 205 to prevent excessive displacement. The high-pressure gas then escapes through the gap between the sliding baffle 206 and the vent pipe 201 until the pressure inside the container equals the external pressure. At this point, the sliding baffle 206 falls back under its own weight, resealing the vent pipe 201 to prevent external dust from entering the container. If the coolant boils and sprays upward, the float 204 rises with the coolant, pushing the sliding baffle 203 upward, thereby sealing the connecting hole 202 above the vent pipe 201, preventing the boiling coolant from overflowing through the vent pipe, and ensuring stable pressure inside the container.
