However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Example:

[0031] See also Figure 1-7 Figure, this embodiment provides a coupling protection cover, including a cover body 1 and a storage box 2, the cover body 1 is provided with a mounting groove 11 for mounting the storage box 2, the storage box 2 is open at the top, the storage box 2 can be pulled out and stored in the lower part of the cover body 1 through the mounting groove 11, the cover body is provided with a through-axis hole 18, the through-axis hole 18 is set through the cover body 1, and the through-axis hole 18 is located above the storage box 2.

[0032] It can be understood that the coupling 6 is arranged through the cover body 1 through the axial hole 18, and the cover body 1 of the coupling protective cover covers the coupling 6 in the cover body 1. When the coupling 6 is running at high speed, the grease on the coupling 6 is thrown around under the action of centrifugal force, and a part of the grease is blocked by the cover body 1, and the other part of the grease is thrown into the receiving box and collected by the receiving box 2. The grease blocked by the cover body 1 partially falls into the receiving box 2 under the action of gravity. Therefore, when the grease on the protective cover needs to be cleaned, it is only necessary to pull the receiving box 2 out of the protective cover and remove the grease in the receiving box 2, and then put the grease back into the cover body 1 to complete the cleaning. The cleaning process is simple and fast, saving time and effort, and effectively preventing the grease from flying out, which is conducive to on-site cleaning and management, and eliminates the safety hazards caused to on-site operators by the flying grease.

[0033] Furthermore, a guide plate 12 is provided at the bottom of the cover body 1, and a plurality of guide plates 12 are provided, and the plurality of guide plates 12 are respectively provided at both sides of the mounting groove 11, and the storage box 2 is placed on the guide plates 12. The bottom of the storage box 2 abuts against the guide plate 12, and the guide plate 12 supports and guides the storage box 2, so that the storage box 2 can be moved smoothly, so that the storage box 2 can be taken out and put in from the inside of the cover body 1.

[0034] Preferably, the top of the cover body 1 is arc-shaped, the inner wall of the top of the cover body 1 is an arc-shaped inner wall, the bottom of the cover body 1 is square, the inner wall of the bottom of the cover body 1 is a square inner wall, and the arc-shaped inner wall of the top of the cover body 1 and the square inner wall of the bottom of the cover body 1 smoothly transition. Except for the vertex, the arc-shaped inner wall at the top has a certain inclination angle relative to the horizontal plane, which is more conducive to the grease attached to the inner wall of the top of the cover body 1 to flow downward, from the arc-shaped inner wall through the square inner wall and into the storage box 2, so that most of the grease is collected in the storage box 2.

[0035] Furthermore, the cover body 1 is provided with an inspection port 13, and the inspection port 13 is provided with a first baffle 3 for shielding the inspection port 13, and the first baffle 3 is movably provided on the cover body 1. The inspection port 13 is provided at the top of the cover body 1, and the first baffle 3 is provided inside the cover body 1. When it is necessary to temporarily inspect the coupling 6 in the cover body 1, the first baffle 3 is opened, and the coupling 6 is inspected through the inspection port 13.

[0036] Furthermore, the cover body 1 is provided with a first slide groove 14, and the first baffle 3 is slidably connected in the first slide groove 14, and is used to cover or open the inspection port 13. When the coupling 6 in the cover body 1 needs to be inspected, the first baffle 3 is pushed to slide in the first slide groove 14, so that the first baffle 3 is moved away from the inspection port 13, so as to open the inspection port 13 to inspect the coupling 6 in the cover body 1. When the inspection port 13 needs to be closed, the first baffle 3 is pushed to slide in the first slide groove 14, so that the first baffle 3 covers the inspection port 13, and prevents the grease on the coupling 6 from being thrown out from the inspection port 13 during the operation of the coupling 6 to injure people or pollute the working environment. In this embodiment, the first slide groove 14 is located in the cover body 1, and the first slide groove 14 is located on the upper and lower sides of the inspection port 13, so that the first baffle 3 slides in parallel to the left and right when sliding in the first slide groove 14. In other embodiments of the present application, the first slide groove 14 may also be located outside the cover body 1, or the first slide groove 14 may be located on the left and right sides of the inspection opening 13, so that the first baffle 3 slides up and down along the slide groove.

[0037] Preferably, the first baffle plate 3 is a curved plate, and the upper surface of the first baffle plate 3 is a curved surface, and the upper surface of the first baffle plate 3 fits with the inner surface of the top of the cover body 1 to prevent a gap from being generated between the first baffle plate 3 and the cover body 1, resulting in poor protection.

[0038] Furthermore, the cover body 1 is provided with a light-transmitting opening 15, and a second baffle 4 is provided at the light-transmitting opening 15 for shielding the light-transmitting opening 15, and the light-transmitting opening 15 is staggered with the inspection opening 13. In this embodiment, the light-transmitting opening 15 is located on the front side of the cover body 1, and the light-transmitting opening 15 is aligned with the inspection opening 13 up and down. When the coupling 6 in the cover body 1 needs to be inspected, the first baffle 3 and the second baffle 4 are opened at the same time, and the external light enters the cover body 1 through the light-transmitting opening 15, thereby enhancing the light intensity in the cover body 1, and facilitating the maintenance personnel to inspect the coupling 6. The inner wall of the cover body 1 is coated with white pigment, so that after the light enters the cover body 1 through the light-transmitting opening 15, it is reflected by the white pigment on the inner wall of the cover body 1, thereby enhancing the light intensity in the cover body 1, and facilitating the maintenance personnel to inspect the coupling 6. After the inspection is completed, the inspection port 13 is shielded by the first baffle 3 , and the light-transmitting port 15 is shielded by the second baffle 4 to prevent the grease on the coupling 6 from being thrown out from the inspection port 13 or the light-transmitting port 15 .

[0039] Furthermore, the cover body 1 is provided with a second slide groove 16, and the second baffle plate 4 is slidably connected in the second slide groove 16, so as to cover or open the light-transmitting opening 15. In this embodiment, the second slide groove 16 is provided inside the cover body 1, and the second slide groove 16 is provided in parallel with the first slide groove 14, so that the second baffle plate 4 slides along the second slide groove 16 to open or close the light-transmitting opening 15. In other embodiments, the second slide groove 16 can also be provided outside the cover body 1 or arranged on the left and right sides of the light-transmitting opening 15.

[0040] Furthermore, the cover body 1 is also provided with an operating mechanism 5 for opening and closing the first baffle 3 and the second baffle 4. The operating mechanism 5 includes a first connecting rod 51, a second connecting rod 52 and an operating rod 53. The operating rod 53 is located outside the cover body 1. The direction in which the first baffle 3 slides relative to the cover body 1 is the same as the direction in which the second baffle 4 slides relative to the cover body 1. One end of the first connecting rod 51 is connected to the first baffle 3, and the other end of the first connecting rod 51 passes through the cover body 1 and is connected to the operating rod 53. One end of the second connecting rod 52 is connected to the second baffle 4, and the other end of the second connecting rod 52 passes through the cover body 1 and is connected to the operating rod 53. When the coupling 6 needs to be inspected, pulling the operating handle can simultaneously drive the first baffle 3 and the second baffle 4 to move simultaneously, so that the inspection port 13 is opened or closed at the same time, which is conducive to saving time for opening or closing the inspection port 13 and the light-transmitting port 15, and is convenient for operation.

[0041] Furthermore, the bottom surface of the cover body 1 is provided with a through hole 17, and the through-shaft holes 18 on both sides of the cover body 1 are long strip holes, and the through-shaft holes 18 are connected to the through holes 17 at the bottom. When the coupling protection cover needs to be installed on the coupling 6, the storage box 2 can be pulled out from the cover body 1, and the cover body 1 can be put on the coupling 6 from top to bottom. The through hole 17 facilitates the coupling 6 to enter the cover body 1, and the long strip hole is conducive to the shafts at both ends of the coupling 6 extending from the long strip hole. Secondly, when the coupling protection cover needs to be removed, it is only necessary to pull out the storage box 2 and then move the cover body 1 out from the top, which is convenient for the disassembly and assembly of the coupling protection cover.

[0042] The technical solution of the utility model is applied, and the working principle and operation process are: when the coupling 6 needs to be protected, first the storage box 2 is pulled out from the cover body 1, and the first baffle 3 and the second baffle 4 are opened, and the cover body 1 is sleeved on the coupling 6 from top to bottom. During the sleeve installation process, the coupling 6 is inserted from the through hole 17 at the bottom of the cover body 1, so that the shafts at both ends of the coupling 6 are located in the through-axis holes 18 at both ends of the cover body 1. During installation, pay attention to observe from the inspection port 13, so that the inspection port 13 and the light-transmitting port 15 are facing the coupling 6 in the cover body 1, and the bottom surface of the cover body 1 is supported on the platform. After the cover body 1 is installed, there needs to be a certain gap between the shafts at both ends of the coupling 6 and the side walls of the through-axis hole 18 to prevent the shafts at both ends of the coupling 6 from contacting and rubbing with the side walls of the through-axis hole 18 during rotation. Insert the storage box 2 from the mounting groove 11 at the bottom of the cover body 1 so that the storage box 2 is located below the coupling 6, push the operating rod 53, move the first baffle 3 and the second baffle 4 at the same time, and close the inspection port 13 and the light-transmitting port 15. During the operation of the coupling 6, the grease on the coupling 6 is thrown to the inner wall of the cover body 1 and the storage box 2, and part of the lubricating oil on the inner wall of the cover body 1 flows from the inner wall of the cover body 1 to the storage box 2 for storage. When it is necessary to clean the waste grease in the storage box 2, just pull the storage box 2 out of the cover body 1 and insert it back after cleaning. When it is necessary to inspect the coupling 6, pull the first baffle 3 and the second baffle 4 through the operating rod 53 to open the inspection port 13 and the light-transmitting port 15 at the same time, and perform a simple inspection on the cover body 1 through the inspection port 13. During the inspection process, the light intensity in the cover body 1 is increased through the light-transmitting port 15 to facilitate the maintenance personnel to inspect the coupling 6. If the coupling 6 needs to be overhauled, the storage box 2 can be pulled out of the cover body 1, and the cover body 1 can be directly removed from the top, which is convenient for disassembly and helps to save disassembly and assembly time.
