[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figure 1-4 As shown, this utility model provides a quick-assembly and disassembly drainage assembly for mobile homes, including a drainage trough 1 laid along the eaves of the mobile home, a water collection hopper 2 located at the corner of the mobile home, a drainage pipe 3, a Z-shaped corner connector 4, a quick-connect fitting 5, and an axial snap-fit ​​structure 6. The water collection hopper 2 is provided with a water outlet 22, and the drainage pipe 3 is connected to the water outlet 22 through the quick-connect fitting 5. The axial snap-fit ​​structure 6 is located between the water collection hopper 2 and the Z-shaped corner connector 4.

[0026] In this embodiment, after rainwater falls onto the roof of the mobile house, it flows into the drainage trough 1 at the eaves. The drainage trough 1 collects the rainwater, and then the rainwater flows along the drainage trough 1 to the drain outlet 13 at its end.

[0027] The Z-shaped corner connector 4 includes a vertical fixing part 42 and a horizontal support part 43. The vertical fixing part 42 is detachably provided on the outside of the corner post of the mobile house by means of fasteners. The horizontal support part 43 extends to the eaves and has a supporting groove 11 on the top surface for installing the drainage channel 1.

[0028] The axial locking structure 6 includes an axial locking protrusion 61 located on the side wall of the water collection hopper 2. The vertical fixing part 42 is provided with an L-shaped latch 62 at the position corresponding to the axial locking protrusion 61. The horizontal section of the L-shaped latch 62 is engaged below the axial locking protrusion 61.

[0029] The axial snap-fit ​​structure 6 allows the water collection hopper 2 and the Z-shaped corner connector 4 to be quickly snapped together and fixed, facilitating installation and disassembly; the quick-connect connector 5 enables the quick connection and separation of the water outlet 22 of the water collection hopper 2 and the drain pipe 3 through a rotating buckle.

[0030] The bottom of the drainage trough 1 is connected to the horizontal support part 43 through an adjustable support frame 41. One end of the adjustable support frame 41 is fixed to the drainage trough 1, and the other end is detachably installed in the support groove 11 through a locking member.

[0031] The locking mechanism of the adjustable support frame 41 facilitates the assembly and disassembly of the drainage channel 1 and the horizontal support 43. These structural designs greatly simplify the installation and disassembly process of the device, saving time and labor costs during the construction and relocation of the mobile house, and adapting to the temporary and mobile characteristics of the mobile house.

[0032] Furthermore, one end of the drainage trough 1 is provided with a drain outlet 13 and a flow guide plug 12, the top of the water collection hopper 2 is provided with a water inlet 21, the flow guide plug 12 is inserted into the water inlet 21 of the water collection hopper 2, and an annular sealing assembly 31 is provided between the two.

[0033] The bottom of the drainage trough 1 is connected to the horizontal support part 43 of the Z-shaped corner connector 4 via an adjustable support frame 41. One end of the adjustable support frame 41 is fixed to the drainage trough 1, and the other end is detachably installed in the support groove 11 via a locking member, thus achieving stable fixation of the drainage trough 1. The filter screen 14 inside the drainage trough 1 covers the drain outlet 13 and is suspended from the hanging ring 15 on the inner wall of the drainage trough 1 via a magnetic hook, which can filter impurities in the rainwater and prevent the drain outlet 13 from clogging. In addition, the elastic buffer pad in the support groove 11 can reduce vibration and wear between the drainage trough 1 and the horizontal support part 43.

[0034] Furthermore, the annular sealing assembly 31 includes a sealing groove on the outer wall of the guide plug 12 and an O-ring embedded in the groove. The sealing groove is located at the docking position after the guide plug 12 is inserted into the inlet 21 of the water collection hopper 2. The guide plug 12 at the end of the drainage trough 1 is inserted into the inlet 21 at the top of the water collection hopper 2, allowing rainwater to flow smoothly into the water collection hopper 2 through the guide plug 12. During this process, the O-ring in the sealing groove on the outer wall of the guide plug 12 forms the first line of defense, preventing rainwater from leaking from the docking point; at the same time, the annular water-blocking rib 23 on the inner wall of the inlet 21 and the outer wall of the guide plug 12 form a labyrinthine water-guiding gap, further blocking rainwater leakage and enhancing the sealing effect.

[0035] Furthermore, the inner wall of the water inlet 21 is provided with at least one annular water-blocking rib 23. The height of the annular water-blocking rib 23 is lower than the upper end face of the flow guide plug 12 when it is fully inserted, forming a labyrinthine water-guiding gap with the outer wall of the flow guide plug 12.

[0036] The O-ring between the flow guide plug 12 and the water inlet 21 forms an effective seal, and the labyrinthine water guide gap between the annular water baffle 23 and the outer wall of the flow guide plug 12 further enhances the sealing effect. The multiple sealing structures ensure that rainwater will not leak during the flow process, thus keeping the mobile house dry.

[0037] Furthermore, the quick-connect fitting 5 includes a male connector, a female connector, a rotating buckle, and a sealing gasket. The male connector is located at the water outlet 22, and the female connector is located at the end of the drain pipe 3. The male connector and the female connector are locked together by the rotating buckle.

[0038] The water collection hopper 2 is connected to the Z-shaped corner connector 4 via an axial snap-fit ​​structure 6. The axial snap-fit ​​protrusion 61 and the L-shaped lock 62 cooperate to achieve quick snap-fit ​​fixation. The vertical fixing part 42 of the Z-shaped corner connector 4 is fixed to the outside of the corner column of the mobile house by fasteners. The supporting groove 11 of the horizontal support part 43 supports the water collection hopper 2. After the rainwater flows into the water collection hopper 2, it flows into the drain pipe 3 through the outlet 22 and the quick-connect fitting 5, and is finally discharged. The male and female ends of the quick-connect fitting 5 are locked by a rotating snap, and the sealing gasket ensures the sealing of the connection.

[0039] Furthermore, the drainage trough 1 is equipped with a removable filter screen 14, which covers the drain outlet 13 and its edge is suspended from the hanging ring 15 on the inner wall of the drainage trough 1 by a magnetic hook.

[0040] The removable filter screen 14 inside the drainage trough 1 can filter impurities such as leaves and mud in the rainwater, preventing impurities from entering the drain outlet 13, water collection hopper 2 and drain pipe 3 and causing blockage, reducing the maintenance cost and frequency of the device, and ensuring smooth drainage.

[0041] Furthermore, an elastic buffer pad is laid inside the supporting groove 11. The elastic buffer pad inside the supporting groove 11 can alleviate the vibration and impact during use, reduce component wear, and extend the service life of the device.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
