Technical Field

[0001] This utility model relates to the field of cooling water pipe technology, specifically to a cooling water pipe for an automobile engine. Background Technology

[0002] Engine cooling water pipes are pipes used in the cooling system. Their main function is to circulate coolant and help the engine dissipate heat. Cooling water pipes usually include several types such as inlet pipes, outlet pipes, and heater pipes.

[0003] Currently, the connection between existing engine coolant hoses and rubber hoses requires forcefully squeezing the end of the rubber hose onto the outer surface of the engine coolant hose end, and then using a clamp to lock the connection. This connection method relies solely on the force of the clamp, making the process cumbersome, and leaks are prone to occur at the connection point after prolonged use. Therefore, this application proposes a new type of coolant hose for automotive engines. Utility Model Content

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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a cooling water pipe for an automobile engine, comprising:

[0028] Engine cooling water pipe body 100;

[0029] The connecting assembly 200 is used to quickly connect the rubber hose 400 to the engine coolant hose body 100. The connecting assembly 200 includes connecting pipes 201 fixed at both ends of the engine coolant hose body 100, and connecting rings 202 fixed at the ends of the connecting pipes 201. The end of the rubber hose 400 is sleeved on the outer surface of the end of the connecting pipe 201. A connecting plate 203 is fixed on the surface of the connecting ring 202, and two symmetrical sliding plates 204 are slidably arranged on the surface of the connecting plate 203. The opposite surfaces of the two sliding plates 204 are each fixed with a semi-circular positioning ring 205 adapted to the rubber hose 400. The connecting assembly 200 also includes a rotating knob 206 disposed on the surface of the connecting plate 203 for driving the two sliding plates 204 to move simultaneously toward the center or to both sides.

[0030] See Figure 1 , Figure 2 The surface of the connecting plate 203 is provided with a strip groove, and the ends of the two sliding plates 204 are slidably connected to the inner wall of the strip groove. The inner wall of the strip groove is rotatably provided with a bidirectional lead screw 207, and the surface of the two sliding plates 204 is provided with a threaded hole that is threadedly connected to the outer surface of the bidirectional lead screw 207.

[0031] Specifically, by setting a bidirectional lead screw 207, the rotation of the bidirectional lead screw 207 can drive the two sliding plates 204 to move simultaneously toward the middle or to both sides.

[0032] See Figure 1 , Figure 2 The top end of the bidirectional lead screw 207 extends to the upper surface of the connecting plate 203, and the rotating knob 206 is fixed to the top end of the bidirectional lead screw 207. The inner top wall of the strip groove is provided with a rotating hole that is rotatably connected to the outer surface of the bidirectional lead screw 207.

[0033] Specifically, the bidirectional lead screw 207 can be automatically rotated by turning the rotary knob 206.

[0034] In this invention, by setting a connecting component 200, when the cooling water pipe is connected to the rubber hose 400, one end of the rubber hose 400 is sleeved on the outer surface of the connecting pipe 201, and the rubber hose 400 is inserted into the inside of the connecting ring 202. Then, rotating the rotating knob 206 drives the bidirectional screw 207 to rotate. The rotation of the bidirectional screw 207 drives the two sliding plates 204 to move towards the middle at the same time, thereby driving the two semi-circular positioning rings 205 to move towards the middle at the same time, effectively clamping and fixing the end of the rubber hose 400 to the end of the connecting pipe 201, thereby realizing the rapid connection between the rubber hose 400 and the engine cooling water pipe body 100.

[0035] See Figure 3 , Figure 4 The connecting ring 202 is provided with a sealing component 300, which includes an annular inflatable airbag 301 fixed to the inner wall of the connecting ring 202.

[0036] Specifically, by setting an annular expansion airbag 301, the expansion of the annular expansion airbag 301 can effectively seal the outer surface of the rubber hose 400 and the connecting pipe 201.

[0037] See Figure 3 , Figure 4 The inner wall of the strip groove has two symmetrical rectangular grooves, and a rectangular plate 302 is fixed on the surface of the sliding plate 204. The rectangular plate 302 is slidably connected to the inner wall of the rectangular groove.

[0038] Specifically, by setting up a rectangular plate 302, the rectangular plate 302 can be moved automatically by sliding the sliding plate 204.

[0039] See Figure 3 , Figure 4 A rectangular telescopic airbag 303 is fixedly installed on the inner wall of the rectangular groove, and the pressing end of the rectangular telescopic airbag 303 is fixedly connected to the surface of the rectangular plate 302.

[0040] Specifically, by setting up a rectangular telescopic airbag 303, the rectangular plate 302 can automatically press the rectangular telescopic airbag 303.

[0041] See Figure 3 , Figure 4 Both rectangular telescopic airbags 303 have inflation tubes at their ends, and the end of the inflation tube away from the rectangular telescopic airbag 303 passes through the connecting ring 202 and extends into the interior of the annular inflatable airbag 301.

[0042] Specifically, by setting up an inflation tube, air inside the rectangular telescopic airbag 303 can be allowed to enter the interior of the annular expansion airbag 301 through the inflation tube after the rectangular telescopic airbag 303 is compressed.

[0043] In this invention, by setting a sealing component 300, during the simultaneous movement of the two sliding plates 204 toward the center, the two sliding plates 204 can respectively compress the two rectangular telescopic airbags 303 through the two rectangular plates 302, thereby allowing the air inside the two rectangular telescopic airbags 303 to enter the interior of the annular expansion airbag 301 through the inflation tube, causing the annular expansion airbag 301 to expand. This effectively presses the inner ring surface of the annular expansion airbag 301 against the end of the rubber hose 400 inserted into the connecting ring 202, thereby achieving the purpose of effectively sealing the connection between the rubber hose 400 and the engine coolant pipe body 100 and preventing leakage.

[0044] Working principle: When the cooling water pipe is connected to the rubber hose 400, one end of the rubber hose 400 is fitted onto the outer surface of the connecting pipe 201, and the rubber hose 400 is inserted into the connecting ring 202. Then, rotating the rotary knob 206 drives the double-acting screw 207 to rotate. The rotation of the double-acting screw 207 drives the two sliding plates 204 to move towards the center simultaneously, thereby driving the two semi-circular positioning rings 205 to move towards the center simultaneously, effectively clamping and fixing the end of the rubber hose 400 to the end of the connecting pipe 201, thus realizing the rapid connection between the rubber hose 400 and the engine cooling water pipe body 100. Next, as the two sliding plates 204 move towards the center simultaneously, they can compress the two rectangular telescopic airbags 303 through the two rectangular plates 302, allowing air from the two rectangular telescopic airbags 303 to enter the interior of the annular expansion airbag 301 through the inflation tube, causing the annular expansion airbag 301 to expand. This effectively presses the inner ring surface of the annular expansion airbag 301 against the end of the rubber hose 400 inserted into the connecting ring 202, thereby effectively sealing the connection between the rubber hose 400 and the engine coolant pipe body 100 and preventing leakage.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
