Specific embodiments
[0022] The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts fall within the scope protected by the present utility model.
[0023] An embodiment of the present utility model provides an automobile engine cooling water connecting pipe. As Figures 1 to 6 shown, the connecting pipe 1 has a low water level section 2. When the automobile engine cooling system stops working, there is residual cooling water in the low water level section 2. A drain pipe 3 is connected to the lower part of the low water level section 2. A concealed hose 4 is pre-connected to the lower edge of the drain pipe 3. A solenoid valve 5 is arranged between the concealed hose 4 and the drain pipe 3. The concealed hose 4 is looped around the outer wall of the drain pipe 3.
[0024] Specifically, in this embodiment, by arranging the drain pipe 3 in the low water level section 2 of the connecting pipe 1, and arranging the solenoid valve 5 and the cooperating concealed hose 4 on the drain pipe 3 for maintenance personnel to easily drain the cooling water, before the maintenance personnel disassemble the connecting pipe 1, they can drain the low water level section 2 where the cooling water may remain in the connecting pipe 1. The concealed hose 4 can drain the cooling water to a designated position, avoiding the situation that the cooling water in the low water level section 2 gushes out and scalds the maintenance personnel when the connecting pipe 1 is disassembled, effectively protecting the personal safety of the maintenance personnel.
[0025] The solenoid valve 5 is a two-way valve. The connecting pipe 1, the solenoid valve 5 and the concealed hose 4 form a drainage path. When the maintenance personnel control the solenoid valve 5 to be connected, the residual cooling water is led out through the concealed hose 4; when the maintenance personnel control the solenoid valve 5 to be closed and the automobile engine cooling system is not operating, the residual cooling water naturally flows to the low water level section 2 and accumulates in the connecting pipe 1.
[0026] Since the concealed hose 4 is looped around the outer wall of the drain pipe 3, when the maintenance personnel need to perform drainage operations, they do not need to prepare the drain pipe 3 anymore and can directly use the concealed hose 4 to drain the cooling water to a preset position, making the operation more convenient.
[0027] Among them, the solenoid valve 5 receives an external opening and closing signal to achieve on and off.
[0028] In a preferred embodiment of the present utility model, an annular groove 6 is formed on the outer wall of the drain pipe 3. An isolation cover 7 is arranged at the notch of the annular groove 6. The annular groove 6 and the isolation cover 7 form an installation cavity. The solenoid valve 5 is fixed in the annular groove 6 and communicates with the drain pipe 3. One end of the concealed hose 4 communicates with the solenoid valve 5 and is coiled along the groove wall of the annular groove 6.
[0029] Specifically, in this embodiment, the isolation cover 7 plays a role in protecting the concealed hose 4 and the solenoid valve 5, avoiding the situation that the concealed hose 4 is worn by friction with other objects, making the structure of the connecting pipe 1 more reliable and improving the practicability.
[0030] In a preferred embodiment of the present utility model, a limiting ring groove 8 is formed on one side of the annular groove 6 in the length direction of the drain pipe 3. One end of the isolation cover 7 is inserted and slidably connected to the limiting ring groove 8. The isolation cover 7 slides to the bottom of the limiting ring groove 8 to expose the concealed hose 4.
[0031] Specifically, in this embodiment, when maintenance personnel need to perform drainage operations, they push the isolation cover 7 to make it partially retract into the limiting ring groove 8, expose the concealed hose 4, and point the end of the concealed hose 4 away from the solenoid valve 5 to a predetermined drainage location. Subsequently, a signal is sent to the solenoid valve 5 to make the solenoid valve 5 conduct, and the concealed hose 4 can then perform drainage operations, with simple and convenient operation.
[0032] In a preferred embodiment of the present utility model, the surface of one end of the isolation cover 7 away from the limiting ring groove 8 has a convex rib 9. The convex rib 9 protrudes from the outer wall of the drain pipe 3, and the side of the convex rib 9 away from the limiting ring groove 8 abuts against the groove wall of the annular groove 6.
[0033] Specifically, in this embodiment, when the maintenance personnel push the isolation cover 7, they can hold the convex rib 9 by hand and push it towards the limiting ring groove 8.
[0034] In a preferred embodiment of the present utility model, a guiding groove 10 for the concealed hose 4 to be embedded is formed on the bottom wall of the annular groove 6.
[0035] Specifically, in this embodiment, the groove wall of the guiding groove 10 is arc-shaped, preferably a minor arc shape, which can not only ensure the wall thickness of the connecting pipe 1 at this place, but also provide a guiding function for the maintenance personnel on how to place the concealed hose 4 after drainage, avoiding the situation that the isolation cover 7 cannot be smoothly closed because the maintenance personnel stack the concealed hose 4 in the installation cavity, or the concealed hose 4 is damaged during the closing process of the isolation cover 7.
[0036] In a preferred embodiment of the present utility model, a positioning block 11 is integrally formed on the side of the convex rib 9 away from the limiting ring groove 8, and a positioning groove 12 for the positioning block 11 to be clamped is formed on the groove wall of the annular groove 6.
[0037] Specifically, in this embodiment, when closing the isolation cover 7, the isolation cover 7 is pulled out from the limit ring groove 8 through the convex rib 9 until the positioning block 11 is clamped in the positioning groove 12, which can avoid the situation that the isolation cover 7 slides due to the vibration during the driving of the vehicle, and improves the connection structure reliability between the isolation cover 7 and the connecting pipe 1.
[0038] In a preferred embodiment of the present utility model, a plurality of limiting blocks 13 are circumferentially and evenly arranged at the notch of the limit ring groove 8, and the isolation cover 7 is provided with a limit groove 14 for the limiting blocks 13 to slide along the length direction of the connecting pipe 1.
[0039] Specifically, in this embodiment, the cooperation between the limiting block 13 and the limiting groove 14 enables the isolation cover 7 to slide along the length direction of the connecting pipe 1, making the sliding process of the isolation cover 7 smoother.
[0040] The drain pipe 3 further includes a sealing cover 15 and a drain pipe body 16. The above-mentioned annular groove 6 is opened on the side of the drain pipe body 16 away from the low water level section 2, and the sealing cover 15 is screwed on the side of the drain pipe body 16 away from the low water level section 2. The outer diameter of the sealing cover 15 is larger than the outer diameter of the isolation cover 7. When assembling the connecting pipe 1, first put the isolation cover 7 on the end of the drain pipe body 16 away from the low water level section 2, slide the isolation cover 7 so that a part of it is inserted into the limit ring groove 8, and then screw on the sealing cover 15.
