Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to an adjustable coupling cover for a centrifugal pump. Background Art

[0002] A coupling cover is a protective device outside the coupling, which is used to surround the rotating coupling in all aspects to prevent safety accidents caused by unsafe operations of operators during the working process of the rotating shaft. It can also prevent the parts on the coupling from splashing and threatening the personal safety of the staff when the coupling is self-damaged. In the mechanical field, coupling covers are required for all couplings exposed outside, so the application scenarios of coupling covers are very extensive. Existing conventional coupling covers are customized products in a one-to-one manner, with non-adjustable length, and can only be used in combination with couplings of specific specifications, resulting in very poor versatility, which will affect the overall inventory management, raw material procurement, and shipping time of the coupling cover. Therefore, an adjustable coupling cover for a centrifugal pump is needed. Summary of the Utility Model

[0003] To make up for the above deficiencies, the utility model provides an adjustable coupling cover for a centrifugal pump, aiming to improve the problem that the length of the existing coupling cover is non-adjustable and can only be used in combination with couplings of specific specifications, resulting in very poor versatility.

[0004] To achieve the above object, the utility model adopts the following technical scheme: an adjustable coupling cover for a centrifugal pump, including a main coupling cover, a main cover rib plate is fixedly connected to the left side inside the main coupling cover, a secondary coupling cover is slidably connected to the right side inside the main coupling cover, a secondary cover rib plate is fixedly connected to the right side inside the secondary coupling cover, fixing plates are fixedly connected to the right parts of the front and rear sides of the main coupling cover, a plurality of limiting holes are evenly formed in the middle of the fixing plates, sliding grooves are formed in the front and rear of the right side of the middle of the main coupling cover, mounting plates are fixedly connected to the front and rear of the left side of the middle of the secondary coupling cover, mounting components are arranged on the upper and lower sides of the opposite sides of the two mounting plates for mounting the coupling cover, and limiting components are arranged on the upper and lower sides of the opposite sides of the two mounting plates for limiting the mounting components during length adjustment.

[0005] As a further description of the above technical solution:

[0006] The mounting component includes a telescopic column, the telescopic column is fixedly connected to the upper and lower sides of the opposite sides of the mounting plate, a spring is arranged on the outer side of the telescopic column, a connecting plate is fixedly connected to the end of the telescopic column far away from the mounting plate, and a limiting shaft is fixedly connected to the side of the connecting plate far away from the telescopic column.

[0007] As a further description of the above technical solution:

[0008] The inner side of the mounting plate is rotatably connected with a mounting shaft, and both ends of the mounting shaft are fixedly connected with limiting plates. The upper and lower sides of the two opposite sides of the mounting plate are rotatably connected with limiting blocks.

[0009] As a further description of the above technical solution:

[0010] Both the main coupling guard and the auxiliary coupling guard are made of aluminum alloy material, and the mounting plate is slidably connected inside the sliding groove.

[0011] As a further description of the above technical solution:

[0012] Mounting holes are formed in the lower parts of both the main guard rib plate and the auxiliary guard rib plate.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected with the mounting plate, and the other end of the spring is fixedly connected with the connecting plate.

[0015] As a further description of the above technical solution:

[0016] The limiting shaft is slidably connected inside the limiting hole, and the connecting plate is slidably connected outside the main coupling guard.

[0017] As a further description of the above technical solution:

[0018] The limiting blocks are fixedly connected to the upper and lower sides of the middle part of the mounting shaft.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, by pressing the connecting plate, the connecting plate makes a relative movement. The connecting plate drives the limiting shaft to move out of the limiting hole and simultaneously squeezes the telescopic column and the spring. Then, by pulling the auxiliary coupling guard, the auxiliary coupling guard drives the mounting plate to slide inside the sliding groove. The mounting plate drives the telescopic column to move, and the telescopic column drives the connecting plate to move, realizing that the adjustable coupling guard for a centrifugal pump can adjust the length without the aid of tools, improving the versatility of the coupling guard.

[0021] 2. In the utility model, through the cooperation among structures such as the main coupling guard, the main guard rib plate, the auxiliary coupling guard, and the auxiliary guard rib plate, it is realized that the coupling guard does not need to be customized one by one. Only by making several basic specifications can most coupling usage scenarios be satisfied, greatly reducing the production management cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1-3The utility model provides an embodiment: an adjustable coupling cover for a centrifugal pump, comprising a coupling main shield 1, a main shield rib plate 2 is fixedly connected to the left side of the inside of the coupling main shield 1, a coupling auxiliary shield 3 is slidably connected to the right side of the inside of the coupling main shield 1, and an auxiliary shield rib plate 4 is fixedly connected to the right side of the inside of the coupling auxiliary shield 3, a fixing plate 6 is fixedly connected to the right side of both front and rear sides of the coupling main shield 1, and a plurality of limiting holes 7 are evenly opened in the middle of the fixing plate 6, a slide groove 5 is opened in the front and rear of the right side of the middle of the coupling main shield 1, and a mounting plate 8 is fixedly connected to the front and rear of the left side of the middle of the coupling auxiliary shield 3, and mounting components are arranged on the upper and lower sides of the two mounting plates 8 for mounting the coupling cover, and the mounting components include a telescopic column 9, and the telescopic column 9 is fixedly connected to the mounting plate 8 on the opposite side. A spring 10 is arranged on the outside of the telescopic column 9, and the end of the telescopic column 9 away from the mounting plate 8 is fixedly connected with a connecting plate 11, one end of the spring 10 is fixedly connected to the mounting plate 8, and the other end of the spring 10 is fixedly connected to the connecting plate 11, and the connecting plate 11 is fixedly connected to a limiting shaft 12 on the side away from the telescopic column 9. Limiting components are arranged on the upper and lower sides of the two mounting plates 8 away from each other, which are used to limit the mounting components when adjusting the length. A mounting shaft 13 is rotatably connected to the inner side of the mounting plate 8, and both ends of the mounting shaft 13 are fixedly connected to the limiting plates 14, and the limiting blocks 15 are rotatably connected to the side away from the mounting plate 8, and the limiting shaft 12 is slidably connected to the inside of the limiting hole 7, and the connecting plate 11 is slidably connected to the outside of the coupling main shield 1, and the limiting blocks 15 are fixedly connected to the upper and lower sides of the middle part of the mounting shaft 13.

[0029] First, by pressing the connecting plate 11 to make it move relatively, the connecting plate 11 drives the limiting shaft 12 to disengage from the limiting hole 7. In this process, the connecting plate 11 will also squeeze the telescopic column 9 and the spring 10, causing the telescopic column 9 to be compressed. Next, the mounting shaft 13 is rotated to drive the limiting plate 14 to rotate, so that the limiting plate 14 is transferred to one side of the connecting plate 11, thereby limiting the connecting plate 11. At this time, pulling the coupling sub-shield 3 will cause the coupling sub-shield 3 to drive the mounting plate 8 to move, further pushing the mounting plate 8 to move the telescopic column 9, and then causing the connecting plate 11 to move accordingly. Finally, the mounting shaft 13 is rotated again to drive the limiting plate 14 to rotate, and the limiting plate 14 is disengaged from the connecting plate 11. In this way, the telescopic column 9 and the spring 10 will no longer be subjected to pressure, thereby resetting and pushing the connecting plate 11, and the connecting plate 11 will eventually drive the limiting shaft 12 to slide into another limiting hole 7, completing the entire adjustment process.

[0030] Reference Figures 1-2 The coupling main shield 1 and the coupling auxiliary shield 3 are both made of aluminum alloy, the mounting plate 8 is slidably connected inside the slide groove 5, and the main shield rib plate 2 and the auxiliary shield rib plate 4 are both provided with mounting holes at the bottom.

[0031] The protective effect of the main coupling guard 1 and the auxiliary coupling guard 3 is improved by using aluminum alloy material. The mounting plate 8 is limited by the sliding groove 5, and the main guard rib 2 and the auxiliary guard rib 4 are installed and fixed through the mounting holes.

[0032] Working principle: When the coupling cover needs to be adjusted, press the connecting plate 11 to make the connecting plate 11 move relatively. The connecting plate 11 drives the limiting shaft 12 to move out of the limiting hole 7 and simultaneously squeezes the telescopic column 9 and the spring 10. Then rotate the mounting shaft 13 to drive the limiting plate 14 to rotate, so that the limiting plate 14 rotates to the side away from the connecting plate 11 to limit the connecting plate 11. Then pull the auxiliary coupling guard 3 to drive the mounting plate 8 to slide inside the sliding groove 5. The mounting plate 8 drives the telescopic column 9 to move, and the telescopic column 9 drives the connecting plate 11 to move. Finally, rotate the mounting shaft 13 to drive the limiting plate 14 to rotate, and the limiting plate 14 rotates away from the connecting plate 11 to release the pressure on the telescopic column 9 and the spring 10, and the spring 10 resets to push the connecting plate 11. The connecting plate 11 drives the limiting shaft 12 to slide into another limiting hole 7. In this way, the adjustable coupling cover for the centrifugal pump can be adjusted without the aid of tools, improving the convenience of coupling cover adjustment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent substitution on some of the technical features.
