Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a coupling with a safety protection structure. Background Art

[0002] A coupling is a mechanical device used to connect two shafts and transmit power or torque. It is often used to solve problems such as misalignment between shafts, angular deviation, or distance difference between shafts. Couplings can transmit power in rotational motion and can absorb and reduce shock and vibration caused by misalignment or vibration of shafts. Couplings are widely used in various mechanical equipment and industrial fields, such as engines, pumps, fans, transmissions, etc.

[0003] For example, the Chinese patent with application number CN202223042445.5 discloses a coupling protection device for a gas turbine, including an upper protective cover and a lower protective cover, the bottom of the upper protective cover is welded with an upper horizontal mounting edge, the top of the lower protective cover is welded with a lower horizontal mounting edge, and the upper horizontal mounting edge and the lower horizontal mounting edge are fixed by bolts and nuts. This scheme adopts an upper and lower separated overall closed design, and separates the protective device up and down at the center plane of the horizontal axis to form two complete and symmetrical upper and lower protective covers. The lower protective cover can receive the lubricating oil in the coupling, and a horizontal mounting edge gasket is provided between the upper horizontal mounting edge and the lower horizontal mounting edge to seal the upper protective cover and the lower protective cover, which can effectively prevent the occurrence of oil leakage and oil seepage.

[0004] However, in actual use, the protective cover of the equipment needs to be disassembled and assembled by screws, which is a cumbersome process. In addition, when the coupling rotates, the lubricating oil inside it will be thrown out by centrifugal force, causing the lubricating oil to splash, which affects the normal working environment.

[0009] By adopting the above technical solution, the anti-collision strip in the solution can buffer the external impact force and effectively protect the equipment.

[0010] A further improvement of the technical solution of the utility model is that: an oil collecting pipe is fixedly connected to the bottom of the lower shell, and a pipe cap is threadedly connected to the bottom of the oil collecting pipe.

[0011] By adopting the above technical solution, the oil collecting pipe in the solution can collect the lubricating oil thrown out by centrifugal force to prevent the lubricating oil from splashing.

[0016] A further improvement of the technical solution of the utility model is that a sealing rubber pad is provided at the connection between the upper shell and the lower shell.

[0017] By adopting the above technical solution, the sealing rubber pad provided at the connection between the upper shell and the lower shell in the solution can prevent the lubricating oil from leaking from the connection between the upper shell and the lower shell, thereby improving the sealing performance of the equipment.

[0018] A further improvement of the technical solution of the utility model is that arc-shaped circular holes are provided on both sides of the protrusion to allow the movable ball to fit in, and when the bottom surface of the protrusion abuts against the top surface of the groove, the movable ball just enters the arc-shaped circular holes provided on both sides of the protrusion.

[0019] By adopting the above technical solution, when the protrusion in the solution is inserted into the groove, the movable ball can just enter the arc-shaped circular holes opened on both sides of the protrusion to fix the protrusion, making the fixation more stable.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

At this time, the elastic force of the second return spring causes the movable ball to be inserted into the through holes set on both sides of the protrusion to achieve locking. When disassembling, it is only necessary to pull the toggle rod to separate the protrusion from the groove, and then rotate the toggle plate to complete the disassembly.

[0022] 2. The utility model provides a coupling with a safety protection structure, which alleviates external impact force through anti-collision strips, and cushions the vibration generated when the upper coupling and the lower coupling rotate, thereby effectively protecting the equipment. The centrifugal force generated when the upper coupling and the lower coupling rotate collects the lubricating oil thrown out through an oil collecting pipe, effectively preventing the lubricating oil from splashing, thereby enhancing the protection effect of the equipment.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-4As shown, the utility model provides a coupling with a safety protection structure, including an upper shell 1, a lower shell 2, an upper half coupling 4, a lower half coupling 5, and an installation component 3, the installation component 3 includes a first fixed block 301, a second fixed block 302, a limit block 303, a latch 304, a first return spring 305, a toggle plate 306, a protrusion 307, a second return spring 308, a movable ball 309, and a groove 310.

The second fixed block 304 is provided with a magnetic block 312. The interior of 02 is a hollow structure, and a latch 304 is connected to the interior of the second fixed block 302, and the bottom of the latch 304 is fixedly connected to the limiting block 303, and the outside of the latch 304 is sleeved with a first return spring 305, and the bottom surface of the first return spring 305 is fixedly connected to the surface of the limiting block 303, and a toggle plate 306 is fixedly connected to the top side of the latch 304, and a protrusion 307 is fixedly connected to the bottom of the toggle plate 306, and a groove 310 is opened inside the first fixed block 301, and through holes are provided on both sides of the groove 310, and a second return spring 308 is fixedly connected inside the through hole, and a movable ball 309 is fixedly connected to the top of the second return spring 308.

[0031] In this embodiment, the first fixed block 301, the second fixed block 302, the limit block 303, the latch 304, the first return spring 305, the toggle plate 306, the protrusion 307, the second return spring 308, the movable ball 309, the groove 310, and the magnetic block 311 are coordinated. The magnetic blocks 311 on the first fixed block 301 and the second fixed block 302 are attracted to each other, and the latch 304 is pulled to drive the limit block 303 and the first return spring 305 to rise, and the first return spring 305 is deformed. At this time, the latch 304 is released and the toggle rod 306 is rotated to align the protrusion 307 with the groove 310. At this time, the elastic force of the second return spring 308 causes the movable ball 309 to be inserted into the through holes set on both sides of the protrusion 307 to achieve locking. When disassembling, it is only necessary to pull the toggle rod 306 to separate the protrusion 307 from the groove 310, and then rotate the toggle plate 306 to complete the disassembly.

[0032] Example 2

[0033] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, at least six groups of anti-collision strips 15 are fixedly connected to the surfaces of the upper shell 1 and the lower shell 2, and two groups of annular buffer pads 14 are provided on the inner walls of the upper shell 1 and the lower shell 2, and the other side of the annular buffer pads 14 is in contact with the upper half coupling 4 and the lower half coupling 5, and an oil collecting pipe 12 is fixedly connected to the bottom of the lower shell 2, and a pipe cap 13 is threadedly connected to the bottom of the oil collecting pipe 12, and a key block 11 is fixedly connected to the inner wall of the upper shell 1 and the lower shell 2, and a second key hole 10 is provided on the surface of the upper half coupling 4 and the lower half coupling 5, and the key block 11 is adapted to the second key hole 10. The input shaft sleeve 7 and the output shaft sleeve 8 are fixedly connected on both sides of the upper half coupling 4 and the lower half coupling 5, and the inner walls of the input shaft sleeve 7 and the output shaft sleeve 8 are provided with a first key hole 9.

When the bottom surface of the protrusion 307 abuts the top surface of the groove 310, the movable ball 309 just enters the arc-shaped circular holes opened on both sides of the protrusion 307.

[0037] In this embodiment, the fixing bolts 6 in the scheme can fix the upper coupling 4 and the lower coupling 5 to prevent them from falling off. The sealing gasket arranged at the connection between the upper shell 1 and the lower shell 2 in the scheme can prevent the lubricating oil from leaking from the connection between the upper shell 1 and the lower shell 2, thereby increasing the sealing performance of the device. When the protrusion 307 in the scheme is inserted into the groove 310, the movable ball 309 can just enter the arc-shaped circular holes opened on both sides of the protrusion 307 to fix the protrusion 307 and make the fixation more stable.

[0038] The following is a detailed description of the working principle of the coupling with a safety protection structure.

[0039] like Figure 1-4As shown, when in use, the magnetic blocks 311 on the first fixing block 301 and the second fixing block 302 are mutually attracted, and the latch 304 is pulled to drive the limit block 303 and the first return spring 305 to rise, and the first return spring 305 is deformed. At this time, the latch 304 is released and the toggle rod 306 is rotated to align the protrusion 307 with the groove 310. At this time, the elastic force of the second return spring 308 causes the movable ball 309 to insert into the through holes set on both sides of the protrusion 307 to achieve locking. When disassembling, it is only necessary to pull the toggle rod 306 to align the protrusion 307 with the groove 310. 7 is separated from the groove 310, and then the toggle plate 306 is rotated to make the protrusion 307 away from the groove 310, so that the first fixing block 301 and the second fixing block 302 are separated to complete the disassembly of the upper shell 1 and the lower shell 2, the anti-collision strip 15 is used to alleviate the external impact force, and the buffer pad 14 is used to buffer the vibration generated when the upper half coupling 4 and the lower half coupling 5 rotate, so as to effectively protect the equipment, and the centrifugal force generated when the upper half coupling 4 and the lower half coupling 5 rotates can collect the thrown lubricating oil through the oil collecting pipe 12.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
