Description

Technical Field

[0001] This invention relates to the field of coupling technology, specifically to a coupling that is easy to replace. Background Technology

[0002] A coupling is a device used to connect components to achieve torque transmission. When connecting a coupling to a machine shaft, locating screws are used for fixing. Locating screw fixing is a common method of connecting couplings to shafts. It uses screws to fix and align the coupling to the shaft, as shown in a locking coupling with application number 2017214286003. However, when using screws to fix the coupling to the machine shaft, multiple screws need to be tightened, leading to inconvenient installation. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a coupling that is easy to replace, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a replaceable coupling comprising two connecting shafts, one end of each connecting shaft being fixedly connected to a connecting disc, a fixing sleeve being embedded inside each connecting shaft, and several storage cavities being opened inside each fixing sleeve, a slider being slidably connected inside each storage cavity, an insert block being fixedly connected to one end of each slider, a spring being sleeved on the outside of each insert block, one end of each spring being fixedly connected to one end of each slider, and the other end of each spring being fixedly connected to one side of the inner cavity of each storage cavity, a pressure post being fixedly connected to the other end of each slider, and a drive sleeve being slidably connected to the outside of each connecting shaft, with one end of each pressure post extending into the drive sleeve.

[0005] Preferably, a side cover is fixedly connected to one end of the drive sleeve and outside the connecting shaft, and an external threaded ring is fixedly connected to the other end of the drive sleeve. A fixing ring is fixedly connected to the outside of the fixing sleeve and behind the drive sleeve. One end of each fixing ring is provided with an internal threaded groove, and one end of each external threaded ring extends into the internal threaded groove and is threadedly connected to the inside of the internal threaded groove.

[0006] Preferably, bolts are inserted inside both connecting discs, one end of each bolt extends to the outside of the connecting disc, and the tail end of each bolt is threaded with a nut.

[0007] Preferably, each of the connecting shafts has a shaft end inserted inside, and each shaft end has a slot on its surface. One end of each insert block is inserted into the corresponding slot.

[0008] Preferably, the surface of the drive sleeve is fixedly connected with a number of friction ridges.

[0009] Preferably, the inner cavity of the drive sleeve is provided with an inclined surface, with the highest point of the inclined surface facing the connecting plate and the lowest point of the inclined surface facing the side cover.

[0010] This invention provides a coupling that is easy to replace, and has the following advantages:

[0011] This easily replaceable coupling, equipped with a drive sleeve, insert blocks, and slots, allows two connecting shafts to be inserted into the outer side of one end of the shaft on the device. Moving the drive sleeve causes the inclined surface inside to push the pressure column towards the shaft end, which in turn pushes the slider and insert blocks, ensuring that one end of each insert block is inserted into the slot. This continues until one end of the external threaded ring is screwed into the internal threaded groove, thus limiting and fixing the positions of the drive sleeve, pressure column, slider, and insert blocks. This allows for the secure fixing of the shaft end to the connecting shaft without the need to tighten multiple screws. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example 1

[0018] Please see Figures 1 to 3The present invention provides a technical solution: a coupling that is easy to replace, comprising two connecting shafts 1, one end of each connecting shaft 1 being fixedly connected to a connecting disc 15, a fixing sleeve 3 being embedded inside each connecting shaft 1, a plurality of storage cavities 4 being opened inside each fixing sleeve 3, a slider 5 being slidably connected inside each storage cavity 4, an insert block 6 being fixedly connected to one end of each slider 5, a spring 7 being sleeved on the outside of each insert block 6, one end of each spring 7 being fixedly connected to one end of each slider 5, and the other end of each spring 7 being fixedly connected to one side of the inner cavity of each storage cavity 4, a pressure column 8 being fixedly connected to the other end of each slider 5, and a driving sleeve 10 being slidably connected to the outside of each connecting shaft 1, with one end of each pressure column 8 extending into the inside of the driving sleeve 10.

[0019] A side cover 9 is fixedly connected to one end of the drive sleeve 10 and outside the connecting shaft 1. An external threaded ring 12 is fixedly connected to the other end of the drive sleeve 10. A fixing ring 18 is fixedly connected to the outside of the fixing sleeve 3 and behind the drive sleeve 10. An internal threaded groove 11 is opened at one end of each fixing ring 18. One end of each external threaded ring 12 extends into the internal threaded groove 11 and is threadedly connected to the inside of the internal threaded groove 11. The position of the drive sleeve 10 can be fixed through the internal threaded groove 11 and the external threaded ring 12.

[0020] Bolts 16 are inserted inside both connecting discs 15. One end of each bolt 16 extends to the outside of the connecting disc 15, and a nut 17 is threaded onto the tail end of each bolt 16. The two connecting discs 15 can be connected by the nut 17 and the bolt 16.

[0021] Each connecting shaft 1 has a shaft end 14 inserted inside, and each shaft end 14 has a slot 13 on its surface. One end of each insert block 6 is inserted into the corresponding slot 13. The shaft end 14 and the connecting shaft 1 are connected by inserting one end of the insert block 6 into the slot 13.

[0022] The surface of the drive sleeve 10 is fixedly connected with several friction ridges, which allow the user to rotate the drive sleeve 10.

[0023] Example 2

[0024] Please see Figures 1 to 2 The present invention provides a technical solution: the inner cavity of the drive sleeve 10 is provided with an inclined surface, and the highest point of the inclined surface faces the connecting plate 15 and the lowest point of the inclined surface faces the side cover 9. Through the inclined surface, when the external threaded ring 12 at one end of the drive sleeve 10 is screwed out from the inner threaded groove 11, the drive sleeve 10 is moved away from the connecting plate 15, so that one end of the pressure column 8 moves along the inclined surface of the inner cavity of the drive sleeve 10, so that the spring 7 pushes the slider 5, the pressure column 8 and the insert block 6 to move, so that one end of the insert block 6 moves out from the slot 13.

[0025] In summary, when using this easily replaceable coupling, the two connecting shafts 1 are respectively inserted into the outer side of one end of the shaft end 14 of the equipment. Then, the drive sleeve 10 is moved, so that the inclined surface inside the drive sleeve 10 pushes the pressure column 8 to move towards the shaft end 14. This causes the pressure column 8 to push the slider 5 and the insert block 6 to move, so that one end of the insert block 6 is inserted into the slot 13 until one end of the external thread ring 12 is screwed into the internal thread groove 11, thereby limiting and fixing the positions of the drive sleeve 10, the pressure column 8, the slider 5, and the insert block 6.

[0026] Then, the two connecting discs 15 are mated together, and one end of the bolt 16 is passed through the two connecting discs 15 and protrudes to the outside of the connecting discs 15. Then, the nut 17 is screwed onto the outside of the tail end of the bolt 16, thereby connecting the equipment with the other equipment through this coupling.

[0027] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of shaft-shaped parts are connected by bearings, the connection position of valve components is provided with anti-leakage rubber strips, the outside of threaded rods or lead rods is provided with dust covers, and the equipment can be driven by either built-in batteries or external power supply. The control method is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this invention is mainly used to protect mechanical devices, this invention will not explain the control method and circuit connection in detail. The external controller mentioned in the specification can play a control role for the electrical components mentioned herein, and the external controller is a conventional known device.
