[0017] The following is in conjunction with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, specific orientation structure, or operation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a pump housing that is easy to position and assemble, including a first base plate 1 and a first pump housing 2. The first pump housing 2 is disposed on the first base plate 1. A second base plate 3 is connected to the side of the first base plate 1. A second pump housing 4 is disposed on the top of the second base plate 3. The second pump housing 4 and the side of the first pump housing 2 are in contact. A positioning groove 5 is recessed on the contact surface of the first base plate 1 and the second base plate 3. A positioning part 6 is disposed on the side of the second base plate 3. The positioning part 6 is inserted into the positioning groove 5.

[0020] like Figure 2 As shown, the second base plate 3 is symmetrically provided with side plates 7 on the top, and the side plates 7 are provided on both sides of the second pump housing 4. The side plates 7 are provided with positioning rods 8 on their sides. The first base plate 1 is symmetrically provided with positioning frames 9 on both sides of the first pump housing 2. The positioning rods 8 are inserted into the positioning frames 9. By inserting the positioning rods 8 into the positioning frames 9, the first base plate 1 and the second base plate 3 are aligned, thereby aligning the threaded holes on the first pump housing 2 and the second pump housing 4, making it easier for the screw to be screwed into the threaded holes.

[0021] like Figure 3As shown, locking cavities 10 are symmetrically arranged at the upper and lower ends of the positioning groove 5. A telescopic rod 11 is provided on the inner wall of the locking cavity 10, and a locking ball 12 is rotatably mounted on the telescopic rod 11. The rotation direction of the locking ball 12 is the same as or opposite to the direction in which the positioning part 6 is inserted into the positioning groove 5, so that the locking ball 12 can rotate when the positioning part 6 is inserted into the positioning groove 5, thus avoiding damage to the locking ball 12. A spring 13 is sleeved on the movable end of the telescopic rod 11. The positioning part 6 is symmetrically arranged with locking grooves 14 at the upper and lower ends, and the locking ball 12 is inserted into the locking groove 14. A push plate 15 is provided between the telescopic rod 11 and the locking ball 12. The push plate 15 is located on the side of the spring 13. A limiting slide rail 16 is symmetrically arranged on the side of the inner wall of the locking cavity 10, and a limiting slide rail 16 is slidably sleeved on the limiting slide rail 16. Positioning block 17 and limiting block 17 are fixedly connected to the side of push plate 15. Positioning part 6 is inserted into positioning groove 5. At the same time, the end of positioning rod 8 presses locking ball 12 into locking cavity 10. At this time, spring 13 and telescopic rod 11 are compressed. Then positioning part 6 moves in positioning groove 5 until locking groove 14 moves directly above locking ball 12. Locking ball 12 bounces up towards locking groove 14 under the action of spring 13 and telescopic rod 11. Locking ball 12 enters locking groove 14. At this time, positioning part 6 is completely inserted into positioning groove 5. First base plate 1 and second base plate 3 are in complete contact. Threaded holes on first pump housing 2 and second pump housing 4 are also in close contact, which facilitates bolt fixing and eliminates the gap between first pump housing 2 and second pump housing 4.

[0022] In this embodiment, the pump housing works as follows: the second plate is brought close to the first plate, so that the positioning part 6 is inserted into the positioning groove 5, the positioning rod 8 is inserted into the positioning frame 9, the positioning part 6 is inserted into the positioning groove 5, and the locking ball 12 enters the locking groove 14 under the action of the spring 13 and the telescopic rod 11, locking the positioning part 6 in the positioning groove 5. At this time, the threaded holes on the first pump housing 2 and the second pump housing 4 are in close contact. No operator control is required, and the first pump housing 2 and the second pump housing 4 are fixed. After that, the operator can assemble the pump housing by means of bolts.

[0023] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
