Description

Technical Field

[0001] This utility model relates to the field of passenger car water tanks, and in particular to a water inlet structure for passenger car water tanks that is easy to inspect. Background Technology

[0002] The design of the water inlet structure of passenger cars is closely related to the performance and maintenance of the vehicle's cooling system. The technical background of passenger car water tank structure that is easy to inspect mainly stems from the need to improve inspection efficiency and accuracy as well as facilitate daily maintenance.

[0003] In existing passenger car water tanks, sealing is mainly achieved through the water tank cap after water is filled. The cap typically consists of a sealing rubber ring, a pressure valve, and a vacuum valve. After the cap is tightened, the rubber ring fits tightly against the edge of the water inlet to form the first physical seal. The threaded structure of the cap and the water inlet further compresses the rubber ring and eliminates gaps to enhance the sealing performance.

[0004] Existing passenger car radiators require the sealing rubber ring to fit tightly against the edge of the inlet, and the threaded or snap-fit ​​structure to be fully locked in order to prevent leakage caused by the cap not being closed tightly. However, due to long-term corrosion from coolant and the effects of alternating high and low temperatures, the sealing rubber ring is prone to aging, hardening, or cracking, leading to a decrease in sealing performance and an increased risk of leakage. Therefore, a passenger car radiator inlet structure that is easy to inspect is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a passenger vehicle water tank inlet structure that is easy to inspect, aiming to solve the problem that the sealing rubber ring is subject to long-term corrosion by coolant and alternating high and low temperatures, which increases the risk of leakage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a water tank inlet structure for passenger vehicles that is easy to inspect, comprising a water tank, an inlet fixedly connected to the top of the water tank, a limiting block one fixedly connected to the outer wall of the inlet, a limiting groove one opened on the inner wall of the water tank, a limiting block two slidably connected to the inner wall of the limiting groove one, a float plate fixedly connected to the outer wall of the limiting block two, a water passage hole opened on the outer wall of the float plate, a float ball fixedly connected to the top of the float plate, a threaded rod fixedly connected to the top of the float ball, a limiting groove two opened on the outer wall of the threaded rod, a water tank cover provided on the top of the inlet, and the inner wall of the water tank cover being threadedly connected to the outer wall of the threaded rod.

[0007] As a further description of the above technical solution:

[0008] The limiting block has a sliding groove inside.

[0009] As a further description of the above technical solution:

[0010] The limiting block has a sliding groove inside.

[0011] As a further description of the above technical solution:

[0012] The slide groove is slidably connected to a limit rod.

[0013] As a further description of the above technical solution:

[0014] The slide is elastically connected to the limiting rod by a spring.

[0015] As a further description of the above technical solution:

[0016] One end of the spring is fixedly connected to the inner wall of the groove, and the other end of the spring is fixedly connected to the outer wall of the limiting rod.

[0017] As a further description of the above technical solution:

[0018] Both the first limiting groove and the second limiting block are provided with three.

[0019] As a further description of the above technical solution:

[0020] The limiting block, limiting rod, spring, and slide groove are all provided in two sets.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the float plate drives the sealing ball to float up under the action of buoyancy. When the water level reaches the preset upper limit, the sealing ball automatically blocks the water flow, effectively preventing excessive water injection. There is no need for manual judgment of the liquid level, which is convenient for detection. It avoids leakage problems caused by human factors such as the cover not being closed tightly or the rubber ring being misaligned, and improves the reliability and durability of the seal.

[0023] 2. In this utility model, the water tank cover and the threaded rod directly cooperate to achieve a seal. The double sealing design enhances the water tank's sealing performance and effectively prevents water leakage. Attached Figure Description

[0031] Reference Figures 1-3 The present invention provides an embodiment of a passenger vehicle water tank inlet structure that is easy to inspect, comprising a water tank 1, a water inlet 2 fixedly connected to the top of the water tank 1 for adding water to the water tank 1 to achieve water storage, a limiting groove 6 is formed on the inner wall of the water tank 1, and a limiting block 7 is slidably connected to the inner wall of the limiting groove 6 to stabilize the limiting block 7 and achieve the sliding connection of the limiting block 7, a float plate 8 is fixedly connected to the outer wall of the limiting block 7 to stabilize the structure of the float plate 8, and a water passage hole 9 is formed on the outer wall of the float plate 8 to disperse the water pressure during water filling and achieve the stability of the float plate 8. The float plate 8 is fixedly connected to the top of the float ball 10. The float plate 8 is used to stabilize the float ball 10 and achieve the sealing effect of the float ball 10. The top of the float ball 10 is fixedly connected to the threaded rod 12. The float ball 10 is used to stabilize the threaded rod structure 12 and achieve the closing effect between the threaded rod 12 and the water tank cover 5. The outer wall of the threaded rod 12 has a limiting groove 11. The limiting groove 11 is used to close the limiting rod 4 and fix the threaded rod 12. The top of the water inlet 2 is provided with a water tank cover 5. The water tank cover 5 is used for sealing and achieves the closing effect of the water tank 1. The inner wall of the water tank cover 5 is threadedly connected to the outer wall of the threaded rod 12. The threaded rod 12 is used to close the water tank cover 5 and achieve the sealing effect of the water tank cover 5.

[0032] Reference Figures 2-4The limiting block 3 has a sliding groove 14 inside, which is used for the sliding action of the limiting rod 4 to achieve the movement effect of the limiting rod 4. The sliding groove 14 is slidably connected to the limiting rod 4 and serves to limit the rod 4 to achieve the function of stabilizing the structure. The sliding groove 14 is elastically connected to the limiting rod 4 through a spring 13. The spring 13 cooperates with the sliding groove 14 and is connected to the limiting rod 4 to achieve the effect of the limiting rod 4 rebounding and resetting. One end of the spring 13 is fixedly connected to the inner wall of the sliding groove 14 and cooperates with the sliding groove 14 to connect to the limiting rod 4 to achieve the effect of the limiting rod 4 rebounding and resetting. The other end of the spring 13 is fixedly connected to the outer wall of the limiting rod 4 and cooperates with the sliding groove 14 to connect to the limiting rod 4 to achieve the effect of the limiting rod 4 rebounding and resetting.

[0033] Reference Figures 2-4 There are three limiting grooves 6 and 7. The limiting groove 6 acts on the limiting block 7 to stabilize the limiting block 7. There are two sets of limiting blocks 3, limiting rods 4, springs 13 and sliding grooves 14. The limiting blocks 3, limiting rods 4, springs 13 and sliding grooves 14 work together to stabilize the threaded rod 12. The inner wall of the limiting groove 11 is adapted to the limiting rod 4. The limiting groove 11 acts on the limiting rod 4 to fix the threaded rod 12.

[0034] Working principle: When filling water tank 1, water is injected into water tank 1 through water inlet 2. The water inside water tank 1 moves the float plate 8 upward due to buoyancy. The float plate 8 is provided with water passage holes 9 to prevent excessive water pressure from preventing the float plate 8 from floating smoothly. The float plate 8 drives the second limiting block 7 to slide in the first limiting groove 6. The first limiting groove 6 has a limiting effect on the float plate 8, making it rise and fall stably and preventing the float plate 8 from shifting its position. The rise of the float plate 8 causes the float ball 10 above and the threaded rod 12 at the top to rise synchronously. The water level is observed by observing the rise of the float ball 10. The outer wall of the threaded rod 12 is provided with the second limiting groove 11. When the water is full, the top of the float ball 10 and the bottom of the water inlet 2 form a seal to prevent water from overflowing. The first limiting block 3 is slidably connected to the limiting rod 4 through the sliding groove 14. The compression spring 13 makes the limiting rod 4 close with the inner wall of the second limiting groove 11 to stabilize the threaded rod 12. The bottom of the water tank cover 5 is aligned with the threaded rod 12. Tightening the water tank cover 5 makes the water tank 1 completely closed.
