[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figs. 1 to 4 As shown, an easy-to-install coupling includes two bushings 3 and a connector for connecting the two bushings 3. The bushings 3 have keyways on their inner sides. The connector includes an upper cover cylinder 1 and a lower cover cylinder 2 that are detachably connected. The upper cover cylinder 1 and the lower cover cylinder 2 have the same structure and are fixed by multiple bolts.

[0018] Two shafts can be connected by using two bushings 3 with a keyway.

[0019] Multiple sets of limiting strips 4 are fixedly connected to the outer side of one end of the bushing 3 inside the connector. The inner sides of the upper cover cylinder 1 and the lower cover cylinder 2 are provided with sliding grooves 5 that are adapted to the limiting strips 4. The bushing 3 is also symmetrically fixedly connected to one end of the bushing 3 inside the connector. The inner sides of the upper cover cylinder 1 and the lower cover cylinder 2 are also provided with sliding grooves 7 that are adapted to the limiting blocks 6.

[0020] The cooperation between the limiting strip 4 and the first slide groove 5 allows the bushing 3 to slide inside the connecting part, while preventing relative rotation between the bushing 3 and the upper cover cylinder 1 and the lower cover cylinder 2, thus improving the stability of the two shaft transmissions. The cooperation between the limiting block 6 and the second slide groove 7 limits the sliding position of the limiting block 6, and further prevents relative rotation between the bushing 3 and the upper cover cylinder 1 and the lower cover cylinder 2.

[0021] The shaft sleeve 3 is provided with a notch at one end outside the connecting piece, and a cover plate 8 is detachably installed at the notch.

[0022] When the distance between the two shafts to be connected is small, the cover plate 8 can be opened, and then the shaft sleeve 3 is installed on the shafts.

[0023] The upper cover cylinder 1 and the lower cover cylinder 2 are provided with a plurality of gaskets 9 between the shaft sleeves 3.

[0024] When the upper cover cylinder 1 and the lower cover cylinder 2 are installed, the gaskets 9 can be placed between the two shaft sleeves 3 according to the needs to improve the stability of the connection of the two shafts, and the coupling can be connected to two shafts with different distances.

[0025] In specific use, the two shaft sleeves 3 are installed on the two shafts respectively, then the lower cover cylinder 2 is placed below the two shaft sleeves 3, the gaskets 9 are placed between the two shaft sleeves 3, and then the upper cover cylinder 1 is installed on the lower cover cylinder 2.

[0026] The parts not disclosed in the utility model are all prior art, and the specific structure and working principle are not described again.

[0027] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the term "includes", "contains" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
