[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an adjustable bearing cover, including a bearing cover body 1, an adjusting mechanism 2 is provided on the bearing cover body 1, and the bearing cover body 1 can be installed on pumps of different models by setting the adjusting mechanism 2, and a positioning mechanism 3 is provided on the bearing cover body 1, and the positioning mechanism 3 can keep the bearing cover body 1 concentric with the central axis of the pump, making it convenient for staff to install the bearing cover body 1.

[0025] The above-mentioned adjusting mechanism 2 includes a mounting block 21, a swivel 22, a connecting rod 23, a mounting hole 24, a return spring 25, and an L-axis 26; the mounting block 21 is slidably connected to the inner wall of the bearing cover body 1, and a mounting hole 24 is opened on the mounting block 21. The bolt is passed through the mounting hole 24, and the bearing cover body 1 can be installed on the pump by using the bolt to cooperate with the mounting block 21. The side wall of the mounting block 21 is fixedly installed with a return spring 25, and the end of the return spring 25 away from the mounting block 21 is fixedly installed on the inner wall of the bearing cover body 1 through the elasticity of the return spring 25, which can drive the mounting block 21 to slide and reset on the inner wall of the bearing cover body 1, and the swivel 22 is rotatably connected to the outer wall of the bearing cover body 1. The side wall of the swivel 22 is fixedly installed with an L-axis 26, one end of the connecting rod 23 is hinged to the outer wall of the L-axis 26, and the other end of the connecting rod 23 is hinged to the outer wall of the mounting block 21. When the swivel 22 rotates, it can drive the mounting block 21 to slide on the inner wall of the bearing cover body 1 in cooperation with the connecting rod 23.

[0026] The above-mentioned positioning mechanism 3 includes a slider 31, a curved arm 32, a positioning rod 33, an arc plate 34, and a positioning spring 35; the slider 31 is slidably connected to the outer wall of the bearing cover body 1, and the outer wall of the slider 31 is hinged with a curved arm 32, and the end of the curved arm 32 away from the slider 31 is hinged to the outer wall of the swivel 22. When the swivel 22 rotates, the slider 31 can be driven to slide on the outer wall of the bearing cover body 1 in cooperation with the curved arm 32, and the inner wall of the slider 31 is slidably connected with the positioning rod 33, and the positioning rod 33 passes through the slider 31, and the positioning rod 33 is slidably connected to the penetration point of the slider 31, and the side wall of the positioning rod 33 is fixedly installed with an arc plate 34, and the outer wall of the arc plate 34 is fixedly installed with a positioning spring 35, and the end of the positioning spring 35 away from the arc plate 34 is fixedly installed on the outer wall of the slider 31. When the slider 31 slides, the arc plate 34 can be driven to move synchronously in cooperation with the positioning spring 35.

[0027] Working principle: Rotate the swivel 22 to make it rotate on the outer wall of the bearing cover body 1. When the swivel 22 rotates, it will drive the L-axis 26 to move synchronously. During the movement of the L-axis 26, it will push the connecting rod 23. At this time, the connecting rod 23 will push the mounting block 21, so that the mounting block 21 slides outward on the inner wall of the bearing cover body 1 and stretches the reset spring 25. At this time, the four groups of mounting blocks 21 on the inner wall of the bearing cover body 1 will slide synchronously and move away from each other, so that the spacing between the four groups of mounting blocks 21 can be flexibly adjusted so that the mounting holes 24 on the mounting blocks 21 remain concentric with the bolt holes on the pump, and by adjusting the spacing between the mounting blocks 21, the bearing cover body 1 can be installed on pumps of different models, making the bearing cover body 1 more applicable and more flexible to use.

[0028] When the swivel 22 rotates, it drives the L-axis 26 to push the connecting rod 23, and the swivel 22 will push the crank arm 32. At this time, the crank arm 32 will push the slider 31, so that the slider 31 slides on the outer wall of the bearing cover body 1. When the slider 31 slides, it will drive the positioning spring 35 to move synchronously. When the positioning spring 35 moves, it will drive the curved plate 34 to move synchronously. When the curved plate 34 moves, it will drive the positioning rod 33 to move synchronously. At this time, the four groups of curved plates 34 on the bearing cover body 1 will move synchronously and approach each other. By approaching each other, the curved plates 34 can be pressed against the outer wall of the central axis of the pump. At the same time, the positioning rod 33 and the slider 31 can make the bearing cover body 1 and the central axis of the pump remain concentric, and then the mounting hole 24 on the mounting block 21 can be kept concentric with the bolt hole on the pump, which makes it convenient for the staff to pass the bolt through the mounting hole 24 and connect it to the bolt hole on the pump.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
