[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the utility model in a schematic manner, so it only shows the structure related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Please refer to Figure 1The utility model provides a mobile air conditioner exhaust pipe joint 100 for connecting a mounting plate 200 and an exhaust pipe 301 of a mobile air conditioner 300 .

[0024] Please refer to Figure 2 A mounting hole 201 is provided on the mounting plate 200 . The mounting hole 201 is substantially circular. A dovetail-shaped positioning groove 202 communicating with the mounting hole 201 is provided at the top of the mounting hole 201 .

[0025] The exhaust pipe joint 100 is generally annular, and includes a body 10 , a latch hook 101 disposed on the outer surface of one end of the body 10 , an elastic hook 102 , and a threaded portion 103 disposed on the inner surface of the other end of the body 10 .

[0026] The outer surface of one end of the body 10 opposite to the threaded portion 103 is recessed toward the center of the exhaust pipe connector 100 to form a step portion 1011 , and the latch hook 101 and the elastic hook 102 are disposed on the outer surface of the step portion 1011 .

[0027] Also, see Figure 4 The latch hook 101 is a block-shaped protrusion structure with a triangular cross-section. The arc length of the mounting plate 200 is 156 mm, and the corresponding central angle is 90°. In the engaged state, the latch hook 101 is engaged in the mounting hole 201 on the mounting plate 200.

[0028] The elastic hook 102 is generally in a sheet-like structure, and the arc length of the mounting plate 200 is 75 mm, and the corresponding center angle is 50°.

[0029] The elastic hook 102 includes an elastic arm 1022 and a limiting protrusion 1021 protruding from the elastic arm 1022 .

[0030] The limiting protrusion 1021 is a protrusion structure with a slope on one side. In the engaged state, the limiting protrusion 1021 abuts against the positioning groove 202 .

[0031] The elastic arm 1022 is roughly in an "L" shape. When the elastic arm 1022 is pressed, the elastic hook 102 is deformed, and the limiting protrusion 1021 slides into the positioning groove 202. After releasing the hand, the elastic hook 102 returns to its original state, and the positioning groove 202 is supported between the limiting protrusion 1021 and the elastic arm 1022.

[0032] An engaging member 104 and a retaining member 105 are provided on an inner surface of the exhaust pipe joint 100 at one end away from the threaded portion 103 .

[0033] The engaging member 104 is a trapezoidal structure, with four engaging members in total, two in each of the left and right semicircles of the exhaust pipe joint 100, and the two engaging members 104 in the left semicircle and the two engaging members 104 in the right semicircle are symmetrically arranged about the center of the circle.

[0034] The clamping piece 105 is a hook-shaped structure with a bayonet. There are two clamping pieces, one in each of the left and right semicircles of the exhaust pipe joint 100, one located in the middle of the two clamping pieces 104 in the left semicircle, and the other located in the middle of the two clamping pieces 104 in the right semicircle.

[0035] The working process of the mobile air conditioner exhaust pipe joint 100 of the utility model is described below in conjunction with the accompanying drawings:

[0036] First, install the exhaust pipe joint 100 on the exhaust pipe 301 , align the side of the exhaust pipe joint 100 with the threaded portion 103 with the exhaust pipe 301 , rotate the exhaust pipe joint 100 perpendicular to the exhaust pipe 301 , and the exhaust pipe 301 can be screwed into the threaded portion 103 .

[0037] Second, see Figure 3 As shown, the exhaust duct connector 100 is installed on the mounting plate 200, the latch hook 101 is obliquely inserted into the mounting hole 201, and the step portion 1011 is now engaged in the mounting hole 201. The exhaust duct connector 100 is rotated to make the latch hook 101 move in the mounting hole 201, and the elastic hook 102 is rotated to face the positioning groove 202, and then the elastic arm 1022 is pressed to deform the elastic hook 102, and the limiting protrusion 1011 slides into the positioning groove 202. After releasing the hand, the elastic hook 102 returns to its original state, and the positioning groove 202 is held between the limiting protrusion 1021 and the elastic arm 1022, so that the exhaust duct connector 100 is fixed on the mounting plate 200 at the upper limit position, thereby improving the installation efficiency. When the exhaust duct connector 100 needs to be removed, the elastic arm 1022 is pressed to deform the elastic hook 102, and the limiting protrusion 1021 is displaced downward. Then, an outward horizontal force is applied to the elastic hook 102. At this time, the limiting protrusion 1021 is horizontally displaced to the outside of the positioning groove 202, and then the latch hook 101 is moved obliquely upward to remove the exhaust duct connector 100.

[0038] Therefore, the mobile air conditioner exhaust pipe joint 100 of the utility model has at least the following beneficial effects:

[0039] The latch hook 101 is used in conjunction with the elastic hook 103. When installing, it can be completed by pressing one elastic hook 103. When disassembling, it can be completed by pressing one elastic hook 103. The exhaust pipe joint 100 has a single structure, is easy to load and unload, and improves installation efficiency.

[0040] The exhaust pipe connector 100 can be completely engaged with the mounting plate 200 , and the structures of the elastic hook 102 and the positioning groove 202 are completely consistent with each other, so that the exhaust pipe connector 100 is not easy to loosen and fall off.
