[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Example 1
[0021] See also Figures 1 to 4 In the embodiment of the utility model, an automobile air-conditioning distribution box comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 is movable on the top of the lower shell 2, an outer ring groove 7 is provided at the connection between the top and the side of the upper shell 1, a connecting ring 8 is fixed at the bottom of the lower shell 2, and the connecting ring 8 is movably inserted in the inner part of the outer ring groove 7, and the upper shell 1 is clamped on the outer ring groove 7 by the connecting ring 8 to dock and position the upper shell 1 and the lower shell 2, so that it is not easy to be misaligned when docking, and the connection is stable, and a sealing ring is also provided on the inner wall of the outer ring groove 7, and the sealing ring is attached to the connecting ring 8, which greatly improves the sealing effect of the connection between the upper shell 1 and the lower shell 2, and improves the sealing performance of the overall automobile air-conditioning distribution box, and a fixing frame 3 is provided on the surface of the lower shell 2 near the lower shell 2, which is a square frame and is installed in a "C" shape on the side of the lower shell 2 for docking with the plug board 5;
[0022] refer to Figure 1 , Figure 3 and Figure 4The fixing frame 3 is provided with a latch assembly 4, which includes a fixing tube 9. The fixing tube 9 is a round tube. The fixing tube 9 is fixed to the surface of the fixing frame 3 and the inside of the fixing tube 9 is connected to the inside of the fixing frame 3, so that the latch rod 10 inside the fixing tube 9 can extend into the fixing frame 3 when it moves. The inside of the fixing tube 9 is movably connected with the latch rod 10. One end of the surface of the latch rod 10 is plugged into the latch hole 6. The plugging here positions the plug plate 5 so that the plug plate 5 is stable in the fixing frame 3. The other end of the latch rod 10 passes through the fixing tube 9 and extends to the outside of the fixing tube 9. A positioning ring 11 is fixed on the surface of the latch rod 10. The positioning ring 11 The main function is to limit the spring member 12 so that the spring member 12 can apply elastic force to the latch rod 10 through the positioning ring 11, so that the latch rod 10 can be stably inserted into the latch hole 6 and is not easy to move out. The surface of the latch rod 10 located inside the fixed tube 9 is movably sleeved with the spring member 12, one end of the spring member 12 moves on the surface of the positioning ring 11, and the other end of the spring member 12 fits the inner wall of the fixed tube 9 away from the fixed frame 3. The end surface of the latch rod 10 inserted into the latch hole 6 and the end of the plug plate 5 are both provided with chamfers. The purpose of designing the chamfers is to squeeze the latch rod 10 when the plug plate 5 is inserted into the fixed frame 3 so that the latch The rod 10 is compressed and automatically retracted into the fixed tube 9. When the latch hole 6 corresponds to the latch rod 10, the latch rod 10 automatically springs into the latch hole 6 under the elastic force of the spring member 12. The upper shell 1 is provided with a plug plate 5, which is movably plugged into the fixed frame 3. The plug plate 5 is provided with a latch hole 6. The latch assembly 4 is movably plugged into the inside of the latch hole 6. A total of five groups of fixed frames 3 and latch assemblies 4 are provided on the upper shell 1 and the lower shell 2. The five groups of fixed frames 3 and latch assemblies 4 match the number of side surfaces on the upper shell 1 and the lower shell 2, and are provided according to the number of side surfaces of the upper shell 1 and the lower shell 2. In order to improve the stability of the connection between the upper shell 1 and the lower shell 2, a The number of positions can be adjusted according to actual conditions. When plugging, after the plug plate 5 is inserted into the fixed frame 3, the plug plate 5 is positioned by plugging the pin rod 10 into the pin hole 6. After the plug plate 5 is positioned, the upper shell 1 and the lower shell 2 can be stably connected. When the upper shell 1 needs to be removed, the pin rod 10 is pulled away from the pin hole 6, and then the upper shell 1 is moved upward. The upper shell 1 drives the plug plate 5 to separate from the fixed frame 3, and the outer ring groove 7 is also separated from the connecting ring 8 on the lower shell 2. In this way, the upper shell 1 can be quickly removed, which improves the disassembly effect. The bolt-free design can avoid the problem of difficult disassembly due to rust of the bolts, and improves the inspection and maintenance efficiency of the entire automobile air-conditioning distribution box.
[0023] Example 2
[0024] refer to Figure 3 and Figure 4A positioning slot 13 is provided on the side of the fixing tube 9 away from the fixing frame 3 and near the latch rod 10. The positioning slot 13 connects the inside of the fixing tube 9 with the outside. A positioning block 14 is provided on the surface of the latch rod 10 located inside the fixing tube 9 and near the positioning slot 13. The size of the positioning block 14 matches the size of the positioning slot 13. In order to stabilize the latch rod 10 in a position after it moves and prevent it from bouncing into the fixing frame 3 again, the positioning slot 13 design is adopted here. First, the latch rod 10 is rotated to drive the positioning block 14. When the latch rod 10 reaches the position of the positioning slot 13, the latch rod 10 is pulled to drive the positioning block 14 to pass through the positioning slot and reach the outside of the fixed tube 9. The latch rod 10 is then rotated again to drive the positioning block 14 to be offset from the positioning slot 13. When the latch rod 10 is released, the positioning block 14 is blocked by the fixed tube 9 to limit the latch rod 10, so that the latch rod 10 cannot move. In this state, the latch rod 10 is away from the latch hole 6, so there is no need to manually pull the latch rod 10 all the time. When it needs to be restored, just follow the above reverse operation.
