[0023] 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.

[0024] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a marine pump housing that is easy to install, comprising a lower housing 1, an upper housing 2 disposed on the top side of the lower housing 1, an isolation plate 4 fixedly connected to the bottom inner wall of the upper housing 2, and semi-circular locking blocks 14 fixedly connected to the outer walls of the isolation plates 4 and 5 on the adjacent side. Lock housings 15 are threadedly connected to the outer walls of the two semi-circular locking blocks 14 for fixing the isolation plates 4 and 5. A positioning shaft 16 is fixedly connected to the rear side of the isolation plate 5, and the positioning shaft 16 is disposed on the isolation plate 4. Inside, a rubber sealing ring 6 is provided at the middle of the isolation plate 4 and the isolation plate 5. An insert shell 7 is fixedly connected to the outer wall of the lower outer shell 1 and the upper outer shell 2. An insert shaft 12 is provided inside the two adjacent insert shells 7. An L-shaped locking block 9 is fixedly connected to the rear outer wall of the lower outer shell 1 and a fixing block 8 is fixedly connected to the rear outer wall of the upper outer shell 2. The fixing block 8 is provided on the inner wall of the L-shaped locking block 9. An insert shaft 10 is slidably connected to the outer wall of the L-shaped locking block 9. A spring 11 is provided on the outer wall of the insert shaft 10 for fixing between the lower outer shell 1 and the upper outer shell 2.

[0025] Specifically, first, the lower outer casing 1 is fitted onto the outer wall of the marine pump and secured with bolts. Next, the upper outer casing 2 is slid into the top side of the lower outer casing 1. Then, the electrical equipment is installed inside the upper outer casing 2 through the rubber sealing ring 6, which can be installed on the side adjacent to the first isolation plate 4 and the second isolation plate 5. Afterward, the second isolation plate 5 is installed on the front side of the first isolation plate 4 via the positioning shaft 16, and the locking housing 15 is threaded onto the outer wall of the two semi-circular locking blocks 14, thus securing the first isolation plate 4 and the second isolation plate 5. Then, the baffle 13 is opened, and the insertion shaft 12 is inserted into the inner wall of the two insertion housings 7. With the reset action of the spring 11, the insertion shaft 10 is inserted into the fixing block 8, thereby completing the installation between the lower outer casing 1 and the upper outer casing 2. In this way, the installation of the outer casing is achieved through a simple structure and operation. Meanwhile, if the rubber sealing ring 6 is damaged, causing moisture intrusion into the electrical equipment inside the upper housing 2, the lock housing 15 can be rotated to disengage it from the two semi-circular locking blocks 14, thereby allowing the second isolation plate 5 to be pulled out from the bottom inner wall of the upper housing 2. Next, a new rubber sealing ring 6 is secured to the adjacent side of the first isolation plate 4 and the second isolation plate 5. Finally, the lock housing 15 is threaded onto the outer wall of the two adjacent semi-circular locking blocks 14, thus replacing the rubber sealing ring 6 and preventing the damaged rubber sealing ring 6 from affecting the protection of the electrical equipment inside the upper housing 2.

[0026] Reference Figures 2-4 The front end of the insert shell 7 is connected to a baffle 13 via a torsion spring. The baffle 13 is located on the outer wall of the insert shaft 12. One end of the spring 11 facing the fixing block 8 is connected to the outer wall of the L-shaped locking block 9, and the other end of the spring 11 is connected to the outer wall of the insert shaft 10. The front sides of the lower outer shell 1 and the upper outer shell 2 are both provided with cover plates 3. The bottom side of the upper outer shell 2 is provided with a sealing groove, and the top side of the lower outer shell 1 is provided with a sealing strip. The sealing strip is located inside the sealing groove.

[0027] Specifically, the baffle 13 can prevent the insertion shaft 12 from detaching from the inside of the insertion shell 7. At the same time, the tension and reset of the spring 11 can realize the insertion and detachment between the insertion shaft 10 and the fixing block 8. The sealing groove is provided to place the sealing strip, which can ensure the sealing of the connection between the lower outer shell 1 and the upper outer shell 2.

[0028] Working principle: The lower outer casing 1 is fitted onto the outer wall of the marine pump and secured with bolts. The upper outer casing 2 is then slid into the top side of the lower outer casing 1. Electrical equipment is then installed inside the upper outer casing 2 through the rubber sealing ring 6. The rubber sealing ring 6 can be installed on the adjacent side of the first isolation plate 4 and the second isolation plate 5. The locking housing 15 is threaded onto the outer wall of the two semi-circular locking blocks 14 to secure the first isolation plate 4 and the second isolation plate 5. Finally, the insertion shaft 12 is inserted into the two insertion housings 7 by opening the baffle 13. The inner wall is then reset by the spring 11, which inserts the shaft 10 into the inside of the fixing block 8 to achieve the installation between the lower outer shell 1 and the upper outer shell 2. At the same time, when the rubber sealing ring 6 is damaged, the locking shell 15 can be rotated to disengage from the two semi-circular locking blocks 14 to pull out the second isolation plate 5 from the bottom inner wall of the upper outer shell 2. Then, the new rubber sealing ring 6 is clamped on the side of the first isolation plate 4 and the second isolation plate 5. Finally, the locking shell 15 is threaded to the outer wall of the two adjacent semi-circular locking blocks 14 to replace the rubber sealing ring 6.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
