Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coupling safety protection, in particular to a protective cover and a machine pump coupling. Background Art
[0002] The coupling is a key component that connects the motor and the pump shaft to transmit torque. During the operation of the pump, the motor will drive the coupling to rotate at high speed, and the coupling is exposed to the outside. However, the high-speed rotating coupling exposed outside the shell poses a considerable safety hazard, which is not only easy to cause harm to nearby personnel, but also affects the good operation of the pump itself (such as rain protection, prevention of foreign objects falling, etc.).
[0003] At present, in order to delay the harm of the surrounding environment to the pump coupling and the life safety of on-site personnel, the relevant industry generally installs a protective cover on the outside of the coupling. However, most protective covers are connected by fixed welding, butterfly nut fastening, and buckle connection. The buckle is easily damaged by repeated opening and closing, and the personnel need to use both hands to operate the buckle or screw the nut to open or close the protective cover when turning the car, which is complicated to operate. At the same time, since the protective cover needs to be opened and closed frequently, once too much force is applied, the cover plate will be over-folded, and the stress on the hinge will easily cause fatigue fracture, resulting in a short service life and inability to effectively protect the coupling.
[0004] Therefore, it is urgent to propose corresponding solutions to the problems that protective covers that use connection methods such as buckles and nut fastening have a complicated operation process, are easily damaged by repeated opening and closing, and have a short lifespan.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0039] In order to overcome the problems of the existing technology that the protective cover using the connection methods such as buckles and nuts is complicated to operate, the buckles are easily damaged by repeated opening and closing, and the service life is short, Figures 1 to 4 As shown, the utility model provides a protective cover on one hand, comprising:
[0040] The cover body 1 includes a first connecting plate 11 and a second connecting plate 12 which are arranged parallel to each other and spaced apart from each other;
[0041] A flip cover plate 2, which is connected to the top of the cover body 1 and forms a chamber for placing the protected object together with the first connecting plate 11 and the second connecting plate 12;
[0042] The magnetic component 3 is arranged on the part of at least one of the cover body 1 and the flip plate 2 facing the other, so that the flip plate 2 can be adsorbed and connected to the first connecting plate 11 and / or the second connecting plate 12 in an openable and closable manner by the magnetic attraction force of the magnetic component 3 and the top of the chamber is closed.
[0043] Specifically, Figure 1 As shown, a magnetic attraction component 3 is provided on at least one of the cover body 1 and the flip cover plate 2, and the magnetic attraction force of the magnetic attraction component 3 is used to adsorb the cover body 1 and the flip cover plate 2, so that the flip cover plate 2 can be adsorbed on the first connecting plate 11 or the second connecting plate 12 in an open and closed manner, or the two sides of the flip cover plate 2 are respectively adsorbed on the first connecting plate 11 and the second connecting plate 12. When the flip cover plate 2 is adsorbed on the top of the cover body 1 by the magnetic attraction force, the flip cover plate 2 and the cover body 1 can form a chamber for placing the protected object, which can prevent external dust and rainwater from entering the protected object and eliminate safety hazards. When it is necessary to observe the specific situation of the protected object, it is only necessary to lift the flip cover plate 2 with one hand, without the need for complex operations such as opening the buckle or removing the nut with both hands. The operation is simple and the labor intensity of personnel is reduced.
[0044] Wherein, in some embodiments, Figure 1 As shown, a plurality of magnetic components 3 are arranged on the top of the first connecting plate 11 along the length direction, a plurality of hinges 4 are arranged at intervals on the top of the second connecting plate 12 along the length direction, one side of the flip plate 2 is hinged to the second connecting plate 12 through the hinge 4, and the other side of the flip plate 2 is connected to the first connecting plate 11 through the magnetic component 3.
[0045] Specifically, combined Figure 1As shown, a magnetic component 3 is provided on the first connecting plate 11, a hinge 4 is provided on the second connecting plate 12, one side of the flip plate 2 is hinged to the second connecting plate 12 through the hinge 4, and the other side is connected to the first connecting plate 11 by the magnetic attraction of the magnetic component 3. The flip plate 2 may be made of iron, so that it can be directly adsorbed to the first connecting plate 11 through the magnetic component 3. Of course, in other embodiments, the magnetic component 3 may also be provided at a position on the flip plate 2 opposite to the first connecting plate 11, and the magnetic components 3 are mutually adsorbed to connect.
[0046] Furthermore, combined with Figure 3 As shown, the magnetic attraction component 3 includes a plurality of receiving grooves opposite to each other, which are respectively arranged on the top of the first connecting plate 11 and on the side of the flip plate 2 facing the first connecting plate 11, and a magnetic attraction block 31 fixedly installed in the receiving grooves, and the receiving grooves are arranged at intervals along the length direction of the first connecting plate 11 and the flip plate 2.
[0047] Specifically, the receiving groove on the top of the first connecting plate 11 and the receiving groove on the side of the flip plate 2 facing the first connecting plate 11 are positioned opposite to each other, so that when the flip plate 2 is closed, the magnetic block 31 in the receiving groove can be adsorbed, thereby closing the flip plate 2 and sealing the top of the chamber accommodating the protected object.
[0048] And, in some embodiments, reference Figure 1 and Figure 4 As shown, it also includes a limit plate 5 connected to the top of the second connecting plate 12, the limit plate 5 includes a vertical plate 51 connected to the side wall of the second connecting plate 12 and a horizontal plate 52 connected to the top of the vertical plate 51 and extending in a direction away from the second connecting plate 12, and the horizontal plate 52 is flush with the top of the second connecting plate 12.

With such a configuration, when the flip plate 2 is opened, the limit plate 5 can support the flip plate 2 and reduce the stress on the hinge 4, effectively avoiding the frequent opening and closing of the protective cover, which may cause the flip plate 2 to be over-folded once force is applied, thereby causing fatigue fracture at the hinge 4, thereby extending the service life of the protective cover.
[0050] Combination Figure 4As shown, the limiting plate 5 is in an "inverted L" shape with its opening facing away from the second connecting plate 12, and the limiting plate 5 is installed in the middle of the length direction of the second connecting plate 12 to avoid uneven force on the supporting flap plate 2. Of course, in other embodiments, multiple limiting plates 5 can also be evenly spaced along the length direction of the second connecting plate 12 to reduce the pressure on a single limiting plate 5, further support the flap plate 2, and effectively prevent the flap plate 2 from being over-folded and causing the hinge 4 to break.
[0051] Wherein, in some embodiments, reference Figure 1 and Figure 2 As shown, the cover body 1 further includes side plates 13 respectively connected to opposite ends of the first connecting plate 11 and the second connecting plate 12, and the flip cover plate 2 and the side plates 13 form an axial hole for the protected object to pass through and extend outside the chamber.
[0052] Specifically, combined Figure 1 and Figure 2 As shown, the two opposite ends of the first connecting plate 11 and the second connecting plate 12 are fixedly connected to the side plates 13 respectively, and the side plates 13 are at right angles to the first connecting plate 11 and the second connecting plate 12, that is, the side plates 13 extend toward the middle, and form an axial hole with the flip cover plate 2 for the protected object to pass through and extend outside the chamber, so that the protected object can pass through the axial hole to prevent dust, rainwater, etc. from entering the protective cover from both ends.
[0053] Wherein, in some embodiments, Figure 1 and Figure 2 As shown, the flip cover plate 2 can be arched, thereby increasing the storage space of the protective cover.
[0054] Wherein, in some embodiments, Figure 1 and Figure 2 As shown, a handle 6 is provided on one side of the flip cover 2 adjacent to the magnetic attraction assembly 3. When manual operation is required to check the protected object, the flip cover 2 can be lifted by manually holding the handle 6, making it easier to open the flip cover 2 of the protective cover. The handle 6 can be welded to the flip cover 2 or detachably connected to the flip cover 2.
[0055] Wherein, in some embodiments, reference Figure 1 and Figure 2 As shown, the protective cover also includes a support plate 7 connected to the bottom of the cover body 1, the support plate 7 includes a side support plate and a horizontal support plate 71 connected to the side support plate and extending in a direction away from the cover body 1, the side support plate is fixedly connected to the side wall of the cover body 1, and the horizontal support plate 71 is connected to the base platform by bolts.
[0056] Specifically, combined Figure 1 and Figure 2As shown, the first connecting plate 11 and the second connecting plate 12 of the cover body 1 are respectively fixedly connected to the side support plates, and a through hole is opened on the horizontal support plate 71 connected to the bottom of the side support plate, through which bolts are passed to be fixedly connected to the base platform, thereby fixing the cover body 1 to prevent the cover body 1 from moving, and the through hole can be a long strip hole to facilitate fine-tuning of the position of the protective cover during installation.
[0057] The second aspect of the utility model provides a machine pump coupling, including a coupling body and the above-mentioned protective cover arranged on the coupling body, the protective cover is sleeved on the outside of the coupling body, so that the coupling body can pass through the axial hole of the protective cover, thereby being covered and protected by the protective cover, avoiding the coupling body from being exposed to the outside and causing safety hazards.

In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
