Technical Field

[0001] The utility model relates to the technical field of key connections of air conditioners, in particular to an air conditioner water inlet and outlet pipe assembly with a pipe orifice leak-proof structure. Background Art

[0002] Central air conditioning is a type of air conditioning that is currently widely used. It is mainly used in commercial public places such as office buildings, cinemas, shopping malls, airports, etc. It can also be used in homes, so it has been recognized and used by many users.

[0003] Due to the high integration and concealment of central air conditioners, they are usually installed in the indoor ceiling. There are usually multiple air outlets in the room, which need to be connected by pipes. The ceiling can decorate the central air conditioner and cover the pipes.

[0004] The pipelines of central air conditioners are complex, and therefore the related components are difficult to replace. In particular, water leakage in the drainage pipes has always been a problem during the use of the air conditioner. Existing air conditioning pipes often need to be lengthened or replaced when in use. However, the existing pipe connection parts are not very convenient to connect and disassemble, and are prone to loosening or axis rotation at the connection parts, resulting in reduced pipe sealing, leakage and seepage, and affecting use. Utility Model Content

[0005] In response to the technical defects in the background technology, the present invention proposes an air-conditioning water inlet and outlet pipe assembly with a pipe opening leak-proof structure, which solves the above technical problems and meets practical needs. The specific technical solution is as follows:

[0006] An air conditioner water inlet and outlet pipe assembly with a pipe opening leak-proof structure comprises a water inlet pipe and a water outlet pipe, wherein the end of the water inlet pipe extends into the water outlet pipe, and a leak-proof structure is provided between the end of the water inlet pipe and the inner surface of the water outlet pipe;

[0007] The leak-proof structure includes a corrugated sealing ring and a first sealing ring sleeved on the outer surface of the water inlet pipe. The corrugated sealing ring is sandwiched between the outer surface of the water inlet pipe and the inner surface of the water outlet pipe. One end of the corrugated sealing ring is fixed to the water inlet pipe, and the other end is in contact with the surface of the first sealing ring.

[0008] A second sealing ring is sleeved on the outer surface of the water outlet pipe. The second sealing ring is fixed to the outer surface of the water outlet pipe and is screwed and fixed to the first sealing ring by screws.

[0009] As an improvement to the above solution, a plurality of grooves 1 are provided on the outer surface of the water inlet pipe near the end, and the grooves 1 are arranged at equal intervals along the length direction of the water inlet pipe and do not exceed the edge position of the corrugated sealing ring.

[0010] As an improvement to the above solution, the bottom of the groove one is arc-shaped, and there are chamfers between the two sides of the groove opening of the groove one and the outer surface of the water inlet pipe.

[0011] As an improvement to the above solution, a plurality of grooves 2 are provided on the inner surface of the water outlet pipe near the end portion, and the grooves 2 are arranged at equal intervals along the length direction of the water outlet pipe.

[0012] As an improvement to the above solution, the bottom of the second groove is arc-shaped, and there are chamfers between the two sides of the notch of the second groove and the inner surface of the water outlet pipe.

[0013] As an improvement to the above solution, a movable gap is reserved between the corrugated sealing ring and the first sealing ring and the outer surface of the water inlet pipe, and a plurality of fixed through holes are provided along the thickness direction of the first sealing ring. The number of the fixed through holes is at least two, and they are arranged around the outer ring of the first sealing ring.

[0014] As an improvement of the above solution, the second sealing ring is integrally formed with the water outlet pipe, and a plurality of fixing through holes 2 are provided along the thickness direction of the second sealing ring. The number of the fixing through holes 2 is at least two and they are arranged around the outer ring of the second sealing ring.

[0015] The beneficial effect of the present invention is that: when in use, the end of the water inlet pipe extends into the water outlet pipe, and the first sealing ring is driven to move toward the second sealing ring by screwing, squeezing the corrugated sealing ring to fill the gap between the water inlet pipe and the water outlet pipe, forming a multiple leak-proof structure, and the fit between the arc and the groove of the corrugated sealing ring increases the contact fitting surface after extrusion deformation, thereby improving the sealing effect. The structure also has good applicability. When the gap between the replaced water inlet pipe and the water outlet pipe is of different sizes, the corrugated sealing ring can be squeezed to adapt to the installation of water inlet pipes and water outlet pipes of different sizes by tightening the first sealing ring and the second sealing ring.

[0020] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0021] like Figures 1 to 3 As shown, an air conditioner water inlet and outlet pipe assembly with a pipe opening leak-proof structure includes an inlet pipe 1 and an outlet pipe 2. The end of the inlet pipe 1 extends into the outlet pipe 2, and a leak-proof structure is provided between the end of the inlet pipe 1 and the inner surface of the outlet pipe 2.

[0022] The leak-proof structure includes a corrugated sealing ring 3 and a first sealing ring 4 sleeved on the outer surface of the water inlet pipe 1. The corrugated sealing ring 3 is sandwiched between the outer surface of the water inlet pipe 1 and the inner surface of the water outlet pipe 2. One end of the corrugated sealing ring 3 is fixed to the water inlet pipe 1, and the other end is in contact with the surface of the first sealing ring 4.

[0023] A second sealing ring 5 is sleeved on the outer surface of the water outlet pipe 2 . The second sealing ring 5 is fixed to the outer surface of the water outlet pipe 2 and is screwed to the first sealing ring 4 by screws.

[0024] Structurally, the leak-proof structure is provided at the overlapping position between the water inlet pipe 1 and the water outlet pipe 2. Preferably, the end diameter of the water inlet pipe 1 is smaller than the end diameter of the water outlet pipe 2. When installing, the end of the water inlet pipe 1 is extended into the water outlet pipe 2, which can effectively avoid the occurrence of a stepped fracture between the water inlet pipe 1 and the water outlet pipe 2. When draining, water will not gather between the water inlet pipe 1 and the water outlet pipe 2 and can be smoothly discharged into the water outlet pipe 2.

[0025] Furthermore, it should be noted that when the end diameter of the water inlet pipe 1 is larger than the end diameter of the water outlet pipe 2, the end of the water outlet pipe 2 extends into the water inlet pipe 1, forming a stepped fracture in the inner wall of the water inlet pipe 1. When the water in the water inlet pipe 1 flows toward the water outlet pipe 2, it will accumulate at the connection position between the water outlet pipe 2 and the water inlet pipe 1, forming accumulated water. The accumulated water will not overflow into the water outlet pipe 2 until the height of the accumulated water is higher than the wall thickness of the water outlet pipe 2, affecting the drainage efficiency. The accumulated water at the connection position between the water outlet pipe 2 and the water inlet pipe 1 is also more likely to cause pipeline leakage.

[0026] In the technical solution of the leakage-proof structure of the present invention, the leakage-proof structure includes a corrugated sealing ring 3 and a first sealing ring 4 sleeved on the outer surface of the water inlet pipe 1. When in use, the first sealing ring 4 moves toward the second sealing ring 5 and squeezes the corrugated sealing ring 3 during the movement, so that the corrugated sealing ring 3 fills the gap between the outer surface of the water inlet pipe 1 and the inner surface of the water outlet pipe 2, thereby sealing and preventing leakage. The number of circles of the corrugated sealing ring 3 is the number of leakage-proof layers of the leakage-proof structure.

[0027] In the technical solution of the water inlet pipe 1 and the water outlet pipe 2 of the present invention, a plurality of grooves 6 are provided on the outer surface of the water inlet pipe 1 near the end thereof. The grooves 6 are arranged at equal intervals along the length direction of the water inlet pipe 1 and do not exceed the edge position of the corrugated sealing ring 3.

[0028] Furthermore, the bottom of the groove 1 6 is arc-shaped, and there are chamfers between the two sides of the groove opening of the groove 1 and the outer surface of the water inlet pipe 1 .

[0029] Furthermore, a plurality of grooves 7 are provided on the inner surface of the water outlet pipe 2 near the end, and the grooves 7 are arranged at equal intervals along the length direction of the water outlet pipe 2; the bottom of the groove 7 is arc-shaped, and there are chamfers between the two sides of the groove opening of the groove 7 and the inner surface of the water outlet pipe 2.

[0030] It should be noted that, generally speaking, the inner and outer surfaces of the bellows sealing ring 3 have undulating arches. When the bellows sealing ring 3 is squeezed by the first sealing ring, the arches on the inner and outer surfaces of the bellows sealing ring 3 protrude toward the water inlet pipe 1 and the water outlet pipe 2, respectively. The arch on the inner surface of the bellows sealing ring 3 fits with the groove 1 6 on the water inlet pipe 1, and the arch on the outer surface of the bellows sealing ring 3 fits with the groove 2 7 on the water outlet pipe 2. After the bellows sealing ring 3 is squeezed and fitted with the groove 1 6 and the groove 2 7, the contact fitting surface after extrusion deformation can be effectively increased, thereby improving the sealing effect.

[0031] It should be noted that both sides of the grooves of groove 1 6 and groove 2 7 have chamfers, which play a guiding role when the corrugated sealing ring 3 is squeezed, so that the two adjacent arches of the corrugated sealing ring 3 can fit closely together, avoiding the edge of the groove from hindering the arch of the corrugated sealing ring 3.

[0032] In the technical solution of the water inlet pipe 1 and the water outlet pipe 2 of the present invention, a movable gap is reserved between the corrugated sealing ring 3 and the first sealing ring 4 and the outer surface of the water inlet pipe 1, and a plurality of fixed through holes 401 are penetrated along the thickness direction of the first sealing ring 4. The number of the fixed through holes 401 is at least two, and they are arranged around the outer ring of the first sealing ring 4.

[0033] Furthermore, the second sealing ring 5 is integrally formed with the water outlet pipe 2 , and a plurality of second fixing through holes 501 are provided along the thickness direction of the second sealing ring 5 . The number of the second fixing through holes 501 is at least two and they are provided around the outer ring of the second sealing ring 5 .

[0034] It should be noted that the water inlet pipe 1 and the water outlet pipe 2 are sealed by screwing the first sealing ring 4 and the second sealing ring 5. The first sealing ring 4 and the second sealing ring 5 are fixed by screwing. The first sealing ring 4 moves toward the second sealing ring 5 when the screw is screwed, which can avoid the axial rotation of the water inlet pipe 1 and the water outlet pipe 2, protect the pipeline, and have a longer service life than the pipeline with axial rotation.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
