Description

Technical Field

[0001] This utility model belongs to the technical field of automotive drain valves, and specifically relates to an adjustable drain valve for vehicles. Background Technology

[0002] Automotive drain valves are indispensable "little guardians" on cars. They work silently in several key areas, and their main responsibility is to efficiently drain accumulated water while preventing external dust and debris from flowing back into the car body. They are crucial for protecting vehicle wiring, preventing corrosion of metal parts, and keeping the car interior dry.

[0003] A drain valve at the bottom of the air tank is used to drain accumulated water and impurities from the brake system's air tank, ensuring reliable operation of the brake system. An improved structure of a vehicle air tank drain valve, disclosed in CN221723486U, includes a housing, a cylinder solenoid valve assembly, and a connector. The connector is a double-ended external threaded connector with through holes at both ends along its length. The outward-facing end of the connector is a large-diameter external threaded connector, and the end connecting to the cylinder solenoid valve assembly is a small-diameter external threaded connector. A convex structure is provided between the large-diameter and small-diameter external threaded connectors, with multiple planes arranged in a ring array on its outer surface. The cylinder solenoid valve assembly has a first vent hole on its side facing away from the connector, which communicates with the through hole of the connector. This drain valve requires only one connector on the cylinder solenoid valve assembly, reducing leakage points, saving installation time, lowering the probability of leakage, and reducing maintenance time and costs. However, its position cannot be adjusted during drainage. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable drain valve for vehicles. Its advantages are that when the adjusting pipe is connected to the drain pipe, the direction of the end can be preset, and the drain position can be flexibly adjusted. At the same time, after the adjusting pipe is installed, it can ensure the stability of the adjusting pipe and prevent it from falling off.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable drain valve for vehicles, including a protective housing, a solenoid valve body built into the protective housing, a connector passing through the protective housing, a drain pipe at the bottom of the solenoid valve body, an adjusting pipe detachably connected to the drain pipe, a retaining edge at the bottom of the protective housing, a through groove on the side wall of the retaining edge, and the adjusting pipe passing through the through groove.

[0006] The above technical solution is adopted as follows: the drain pipe and the regulating pipe are connected by an interference fit, the end of the drain pipe is inserted into the inner cavity of the regulating pipe, the solenoid valve body is installed to the bottom of the air tank through the connector, the direction of the end of the regulating pipe is adjusted, and then the regulating pipe is installed on the drain pipe at the bottom of the solenoid valve body. Because the preset direction of one end of the regulating pipe is different, the direction of the solenoid valve body draining is different.

[0007] When the regulating pipe is installed on the drain pipe, it can pass through the through-hole at different positions depending on the orientation of its end.

[0008] The present invention is further configured such that the protective shell includes a left shell and a right shell, and the left shell and the right shell are detachably connected.

[0009] The above technical solution is adopted: the left and right housings cooperate to form a protective shell, which can protect the solenoid valve body from being damaged by impacts from other objects.

[0010] The present invention is further configured such that the top of both the left and right shells is provided with an arc-shaped upper clearance groove, and the bottom of both the left and right shells is provided with a lower clearance groove.

[0011] The above technical solution is adopted: the upper clearance grooves on the top of the left and right shells cooperate to form a hole through which the top of the connector passes, and the lower clearance grooves on the bottom of the left and right shells cooperate to form a hole through which the drain pipe and the regulating pipe can pass.

[0012] The present invention is further configured such that an inner positioning cylinder with an insertion hole is fixedly provided on one side of the top inner wall of the left housing, and an inner positioning post that can be interference-fitted into the insertion hole of the inner positioning cylinder is installed on one side of the right housing.

[0013] The above technical solution, with the cooperation of the inner positioning cylinder and the inner positioning column, facilitates the installation and positioning between the left and right housings.

[0014] The present invention is further configured such that an outer positioning cylinder with an insertion hole is fixedly provided at the bottom of the left housing, and an outer positioning post that can be interference-fitted into the insertion hole of the outer positioning cylinder is installed on one side of the right housing.

[0015] By adopting the above technical solution, the outer positioning cylinder and the outer positioning column work together to further improve the stability of the connection between the left and right shells.

[0016] The present invention is further configured such that a wire hole is provided on the right housing.

[0017] Using the above technical solution: the wiring connected to the solenoid valve body can be led out through the wire hole.

[0018] The present invention is further provided that diagonal rods are connected to both sides of the inner wall of the through groove.

[0019] The above technical solution is adopted: the diagonal bars on both sides of the through groove are symmetrically arranged. The diagonal bars are made of elastic metal and have elastic deformation capability. When the regulating pipe is connected to the drain pipe and passes through the through groove, the diagonal bars on both sides of the through groove can limit the regulating pipe and prevent the regulating pipe from falling off.

[0020] The present invention is further configured such that an arc-shaped piece is connected to the end of the inclined rod.

[0021] The above technical solution is adopted: when the regulating tube passes through the groove, the regulating tube is located between two arc-shaped plates, and the opening formed between the two inclined rods facing one end of the arc-shaped plates is smaller than the diameter of the regulating tube.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model adds an adjusting pipe to the bottom of the drain pipe. The direction of the adjusting pipe can be preset. The direction of drainage is different depending on the direction of one end of the adjusting pipe.

[0023] 2. This utility model provides a through-groove through which the regulating tube passes, and sets diagonal bars and arc-shaped pieces on both sides of the through-groove to limit the regulating tube, ensuring its stability and preventing it from falling off. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: refer to Figure 1 and Figure 2An adjustable drain valve for vehicles includes a protective housing 1, a solenoid valve body 2 built into the protective housing 1, a connector 3 connected to the solenoid valve body 2 passing through the protective housing 1, a drain pipe 4 at the bottom of the solenoid valve body 2, and an adjusting pipe 9 detachably connected to the drain pipe 4.

[0028] The drain pipe 4 and the regulating pipe 9 are connected by an interference fit. The end of the drain pipe 4 is inserted into the inner cavity of the regulating pipe 9. The solenoid valve body 2 is installed to the bottom of the air tank through the connector 3. Then, the direction of the end of the regulating pipe 9 is adjusted. Then, the regulating pipe 9 is installed on the drain pipe 4 at the bottom of the solenoid valve body. Because the preset direction of one end of the regulating pipe 9 is different, the direction of the solenoid valve body 2 when draining is different.

[0029] refer to Figure 2 The protective housing 1 includes a left housing 5 and a right housing 6, which are detachably connected.

[0030] The left housing 5 and the right housing 6 work together to form a protective outer shell 1, which can protect the solenoid valve body from being damaged by impacts from other objects.

[0031] refer to Figure 2 The top of both the left shell 5 and the right shell 6 is provided with an arc-shaped upper clearance groove 7, and the bottom of both the left shell 5 and the right shell 6 is provided with a lower clearance groove 8.

[0032] The upper clearance grooves 7 on the top of the left housing 5 and the right housing 6 cooperate to form a hole through which the top of the connector 3 passes. The lower clearance grooves 8 on the bottom of the left housing and the right housing 6 cooperate to form a hole through which the drain pipe 4 and the regulating pipe 9 pass.

[0033] refer to Figure 2 and Figure 3 An inner positioning cylinder 14 with an insertion hole is fixedly provided on one side of the top inner wall of the left housing 5. An inner positioning post 15 that can be interference-fitted into the insertion hole of the inner positioning cylinder 14 is installed on one side of the right housing 6. An outer positioning cylinder 16 with an insertion hole is fixedly provided at the bottom of the left housing 5. An outer positioning post 17 that can be interference-fitted into the insertion hole of the outer positioning cylinder 16 is installed on one side of the right housing 6.

[0034] The inner positioning cylinder 14 and the inner positioning post 15 work together to facilitate the installation and positioning between the left housing 5 and the right housing 6. The outer positioning cylinder 16 works with the outer positioning post 17 to further improve the stability of the connection between the left housing 5 and the right housing 6.

[0035] refer to Figure 2 and Figure 3 A wire hole 18 is provided on the right shell 6.

[0036] The wiring connected to the solenoid valve body 2 can be led out through the wire hole 18.

[0037] Brief description of the usage process: Pre-adjust the orientation of the end of the regulating pipe 9, and then make an interference fit between the regulating pipe 9 and the drain pipe 4. The regulating pipe 9 is installed on the drain pipe 4 and is used to drain the accumulated water. When draining the accumulated water, the accumulated water will be drained in the direction set in advance at the end of the regulating pipe 9.

[0038] Example 2: Based on Example 1, and referring to Figure 1 and Figure 2 An adjustable drain valve for vehicles also includes a through groove 11. The bottom of the protective housing 1 has a retaining edge 10, and the side wall of the retaining edge 10 is provided with the through groove 11. The adjusting tube 9 can pass through the through groove 11.

[0039] When the regulating pipe 9 is installed on the drain pipe 4, it can pass through the through groove 11 at different positions depending on the orientation of its end. The through groove 11 plays a certain limiting role for the regulating pipe 9.

[0040] refer to Figure 3 and Figure 4 Both sides of the inner wall of the groove 11 are connected with diagonal rods 12.

[0041] The inclined rods 12 on both sides of the through groove 11 are symmetrically arranged. The inclined rods 12 are made of elastic metal and have elastic deformation capability. When the regulating pipe 9 is connected to the drain pipe 4 and passes through the through groove 11, the inclined rods 12 on both sides of the through groove 11 can limit the regulating pipe 9 and prevent the regulating pipe 9 from falling off.

[0042] refer to Figure 3 and Figure 4 An arc-shaped piece 13 is connected to the end of the diagonal rod 12.

[0043] When the regulating tube 9 passes through the slot 11, the regulating tube 9 is located between the two arc-shaped pieces 13, and the opening formed between the two inclined rods 12 facing one end of the arc-shaped piece 13 is smaller than the diameter of the regulating tube 9.

[0044] Brief description of the usage process: When the regulating pipe 9 is installed on the drain pipe 4, the regulating pipe 9 is pressed on the two inclined rods 12, causing the two inclined rods 12 to deform, and the two arc-shaped pieces 13 on both sides of the through groove 11 to move away from each other. Then the regulating pipe 9 passes through the area between the two arc-shaped pieces 13 and through the through groove 11. The two inclined rods 12 are reset, which plays a limiting role for the regulating pipe 9.

[0045] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0046] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
