[0001] The present application relates to the technical field of water pump accessories, and in particular to a novel water pump guide plate. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid, and is widely used in industries, agriculture, construction, etc. The guide plate is an important component of a water pump, which guides the water flow and improves the efficiency of the water pump.

[0003] The main body of the guide plate is usually a disc-shaped metal or plastic material with blades formed on its surface to change the flow direction and speed of the fluid. A connecting ring is usually protruding from the center, which is used to connect components such as the impeller. The connection is generally flat and uses a matching rubber flat washer.

[0004] With regard to the above-mentioned related technologies, the method of connecting the rubber rings to the surface of the connecting ring is easy to fall off and deform, causing leakage of the water pump and affecting performance. Utility Model Content

[0005] In order to improve the sealing effect of the water pump, the present application provides a new type of water pump guide plate.

[0006] This application provides a new type of water pump guide plate, which adopts the following technical solution:

[0007] A new type of water pump guide plate includes a guide plate body and a connecting ring fixed on the guide plate body. The end surface of the connecting ring facing away from the guide plate body is provided with a groove, and the groove is provided along the circumference of the connecting ring. One side of the sealing ring can be snapped into the groove.

[0008] By adopting the above technical solution, a connecting ring is introduced and a circumferential groove is opened on it, so that the sealing ring can be firmly clamped in the groove, reducing the risk of the sealing ring falling off and deforming, and effectively improving the sealing performance between the water pump guide plate and the sealing ring, as well as the stability of equipment operation.

[0009] Optionally, a limiting ring is provided on the connecting ring, and the limiting ring is provided on the side wall of the groove and is located at an end away from the bottom wall of the groove.

[0010] By adopting the above technical solution, a limiting ring is added to the side wall of the groove of the connecting ring, which further strengthens the positioning effect of the sealing ring, prevents the sealing ring from accidentally falling out under vibration, and further improves the stability and reliability of the sealing structure.

[0011] Optionally, the limiting ring is integrally formed with the connecting ring, and the connecting ring and the limiting ring are both provided with chamfers on one side facing the groove.

[0012] By adopting the above technical solution, the chamfering treatment of the connecting ring and the limiting ring on the side facing the groove reduces the friction and resistance during the installation process, improves the assembly efficiency, and protects the sealing ring from damage.

[0013] Optionally, it further includes a clamping block and a driving member, wherein a sliding groove for the clamping block to slide is provided on the connecting ring and the side wall of the groove, and the driving member can drive the end of the clamping block to slide into the groove.

[0014] By adopting the above technical solution and adding a clamping block and a driving member, dynamic compression of the sealing ring is achieved, thereby enhancing the sealing effect.

[0015] Optionally, a limiting block is arranged on the side of the pressing block away from the groove, a limiting groove for sliding of the limiting block is opened on the connecting ring, the limiting groove is connected with the sliding groove, and the limiting block can limit the pressing block from completely entering the groove.

[0016] By adopting the above technical solution, the use of the limit block and the limit groove effectively limits the travel of the pressing block during the sliding process, preventing the pressing block from over-pressing the sealing ring or completely entering the groove and being unable to reset. This design ensures that the sealing ring is subjected to appropriate pressure while maintaining the stability and maintainability of the structure.

[0017] Optionally, the driving member is a driving ring, and a slot for inserting the driving ring is formed on the end face of the connecting ring, the side of the limiting groove away from the groove is connected to the slot, and the inner diameter of the slot is larger than the outer diameter of the groove, and a guide slope is provided on the side of the limiting block away from the clamping block.

[0019] Optionally, the driving ring is provided with a thread, and the connecting ring is provided with a thread matching the driving ring on a side wall of the slot.

[0020] By adopting the above technical solution, a thread is provided on the driving ring, and a matching thread is provided on the side wall of the slot of the connecting ring, and the driving ring is inserted into the slot by rotation, thereby improving operability and stability.

[0021] Optionally, chamfers are provided on both upper and lower sides of one end of the pressing block facing the groove.

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] Example 1

[0033] The present application embodiment discloses a new type of water pump guide plate. Figure 1 The guide plate includes a guide plate body and a connecting ring 2 integrally formed with the guide plate body. A groove 21 is provided on the end face of the connecting ring 2 that is away from the guide plate body. The groove 21 extends into a circular ring along the circumferential end face of the connecting ring 2, so that one side of the sealing ring can be snapped into the groove 21, so that the sealing ring is not easily moved and deformed relative to the connecting ring 2; thus, when the guide plate is connected to the corresponding impeller, not only the sealing ring is firmly fixed, but also the overall sealing performance of the water pump is significantly improved.

[0034] Reference Figure 1 and Figure 2 In the present embodiment, further, a limiting ring 3 is provided on the connecting ring 2. The limiting ring 3 is preferably integrally formed on the side wall of the groove 21 and is located at one end of the bottom wall of the groove 21. Thus, the multi-sealing ring further plays a limiting role, effectively preventing it from accidentally falling off from the groove 21, and further enhancing the sealing performance of the water pump.

[0035] Meanwhile, to facilitate the installation of the sealing ring, the connecting ring 2 and the edge of the limiting ring 3 are both rounded at the edge of the groove 21, so as to facilitate the clamping of the sealing ring into the groove 21.

[0036] The implementation principle of a new type of water pump guide disk in this application embodiment is as follows: The groove 21 is opened, providing a stable and precise placement space for the sealing ring, ensuring that it can be firmly fixed in the groove 21, thereby greatly reducing the possibility of falling off. At the same time, the specific structure of the groove 21 plays a good supporting and protecting role for the sealing ring, effectively preventing it from deforming, and thus ensuring the sealing performance of the water pump. At the same time, the limiting ring 3 can further increase the limiting effect on the sealing ring and improve the stability of the sealing ring.

[0037] Embodiment 2

[0038] The difference between this application embodiment and Embodiment 1 is that a pressing block 4 and a driving block are further added. Refer to Figure 3 and Figure 4 , in this embodiment, the connecting ring 2 is provided with a sliding groove 22 for the pressing block 4 to slide on the side wall of the groove 21. The sliding groove 22 is located on the side of the groove 21 away from the axis of the connecting ring 2, and the groove 21 extends along the direction perpendicular to the axis of the connecting ring 2. The driving member 5 can drive the end of the pressing block 4 to slide into the groove 21, so as to more tightly press against the sealing ring installed in the groove 21.

[0039] Refer to Figure 3 and Figure 4 , specifically, the driving member 5 is set as a driving ring 51. At the same time, a slot 24 for inserting the driving ring 51 is opened on the end face of the connecting ring 2. The inner diameter of the slot 24 is larger than the outer diameter of the groove 21, that is, the slot 24 is arranged outside the groove 21. At the same time, a limiting block 6 is fixed to the end of the pressing block 4 away from the groove 21. The length of the limiting block 6 along the axis direction of the connecting ring 2 is greater than that of the pressing block 4. A limiting groove 23 for the limiting block 6 to slide is also opened on the connecting ring 2. The limiting groove 23 is communicated with the sliding groove 22. Thus, when the pressing block 4 slides in the sliding groove 22, the cooperation between the limiting block 6 and the limiting groove 23 can limit the pressing block 4 from sliding into the groove 21.

[0040] The side of the limiting groove 23 away from the groove 21 is connected to the slot 24. When the abutting block 4 is received in the slide groove 22, the limiting block 6 partially slides into the slot 24. Furthermore, a guide slope is provided on the side of the limiting block 6 away from the abutting block 4. The guide slope faces the side of the connecting ring 2 away from the guide plate body 1. When the driving ring 51 is inserted into the slot 24, the end face of the driving ring 51 first abuts against the guide slope, driving the limiting block 6 to move toward the abutting block 4, thereby driving the abutting block 4 to slide into the groove 21, squeezing the side wall of the sealing ring, further abutting the sealing ring, and improving the stability of the sealing ring. Preferably, multiple groups of abutting blocks 4 and limiting blocks 6 can be arranged along the circumference of the connecting ring 2, and the driving ring 51 can drive all limiting blocks 6 and abutting blocks 4 to slide together.

[0041] Preferably, in order to improve the cooperation between the limiting ring 3 and the clamping block 4, the limiting ring 3 is arranged on the inner wall of the groove 21. After the sealing ring is squeezed by the clamping block 4, it is squeezed toward the inner side of the limiting ring 3. In combination with the limiting ring 3, the limiting effect on the sealing ring can be improved.

[0042] Reference Figure 3 and Figure 4 In order to facilitate the insertion of the drive ring 51 into the slot 24, a thread is provided on the outer wall of the drive ring 51. At the same time, the connecting ring 2 is provided with a thread adapted to the drive ring 51 on the outer wall of the slot 24, so that the drive ring 51 is rotated. Through the threaded fit, the drive ring 51 can be conveniently inserted into the slot 24. And through the threaded connection, the drive ring 51 can be fixed to prevent it from sliding out of the slot 24, thereby improving the stability of the card block when it is pressed against the sealing ring. At the same time, further optionally, a card slot can be provided on the end face of the drive ring 51, and the card block or other adapter tools can apply force to the drive ring 51 during rotation to facilitate the rotation of the drive ring 51.

[0043] Reference Figure 3 and Figure 4 In this embodiment, in order to further improve the clamping effect of the block on the sealing ring, both upper and lower sides of the end of the block facing the groove 21 are designed to be chamfered. This chamfer design can further increase the clamping effect of the block on the sealing ring.

[0044] The implementation principle of a new type of water pump guide plate in the embodiment of the present application is: when installing the sealing ring, first insert the sealing ring into the groove 21, and then rotate the force ring into the slot 24. At this time, the limit block 6 is driven by the force of the force ring to drive the clamping block 4 to slide toward the groove 21, thereby further clamping the sealing ring.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
