Due to the small size of the bolts and nuts, it is difficult to preserve them and they are easy to lose. Therefore, it is very inconvenient to use, and the process of finding parts is also very time-consuming, which reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-2 In this embodiment, an elastic coupling for easy maintenance of a transmission machinery includes a left coupling 1, a right coupling 2 is provided on the right side of the left coupling 1, a sealing block 3 is fixed to the left end of the right coupling 2, a sealing groove 4 is opened on the right side of the left coupling 1, four boxes 5 are fixed on the right side of the outer surface of the left coupling 1, a limiting seat 9 is fixed on the left side of the inner wall of the box 5, four fixing seats 7 are fixed on the left side of the outer surface of the right coupling 2, a limiting plate 8 is fixed on the left side of the fixing seat 7, and a limiting mechanism 6 for disassembly and assembly of the coupling is provided on the box 5.

[0023] It should be noted that the limiting mechanism 6 is mainly used to improve the convenience of disassembly and assembly between the left coupling 1 and the right coupling 2, and effectively improve the subsequent maintenance work on the coupling, while improving work efficiency.

[0024] See also Figure 1 and Figure 3In order to facilitate the disassembly and assembly of the coupling, the limiting mechanism 6 includes a threaded rod 601 rotatably connected to the top right side of the inner wall of the box body 5 through a bearing, and the left and right sides of the outer surface of the threaded rod 601 are threadedly connected with movable blocks 602, and the top surface of the movable block 602 is fixed with a slider 603, and the two sliders 603 on the same box body 5 are slidably connected with a slide groove 604, and the bottom surface of the movable block 602 is hinged with a hinged rod 605, and the bottom ends of the two hinged rods 605 on the same box body 5 are hinged with a limiting block 606, a handle 607 is fixed to the left end of the threaded rod 601, and a nut 608 is threadedly connected to the left side of the outer surface of the threaded rod 601.

[0025] Among them, the sealing block 3 is annular, the sealing groove 4 is an annular sealing groove, and the sealing block 3 is inserted into the sealing groove 4 and matched with the gap therein, which can improve the sealing between the left coupling 1 and the right coupling 2.

[0026] At the same time, a limiting groove is opened on the right side of the limiting seat 9, and the left end of the limiting plate 8 is inserted into the limiting groove and matched with its clearance. After the limiting plate 8 is inserted into the limiting groove, the stability of the limiting plate 8 can be improved, which is convenient for the subsequent limiting block 606 to limit the limiting plate 8.

[0027] In addition, a clearance hole is opened on the right side of the box body 5, and the limit plate 8 passes through the clearance hole and extends to the interior of the box body 5. The limit plate 8 is inserted into the box body 5, and the limit plate 8 is limited by the limit block 606, thereby completing the fixing process between the left coupling 1 and the right coupling 2.

[0028] It can be understood that the threads on the left and right sides of the outer surface of the threaded rod 601 are in opposite directions. When the threaded rod 601 rotates, the two movable blocks 602 on the same threaded rod 601 can move in opposite directions. The sides of the two movable blocks 602 on the same box body 5 are provided with threaded holes. The threaded rod 601 passes through the two threaded holes and is threadedly connected to them. When the threaded rod 601 rotates, it can drive the movable block 602 to move left and right.

[0029] It should be emphasized that a slot is provided on the top surface of the limit plate 8 , and the limit block 606 enters and exits the slot and cooperates with the gap therein. When the limit block 606 is inserted into the slot, it can limit the limit plate 8 .

[0030] Finally, a through hole is opened at the top of the left side of the box body 5, and the threaded rod 601 passes through the through hole and extends to the outside of the box body 5, so that the threaded rod 601 can be driven to rotate by the handle 607. The nut 608 fits tightly with the top of the left side of the box body 5. The nut 608 increases the friction between the box body 5 and the stability of the threaded rod 601, thereby preventing the threaded rod 601 from rotating under the action of external force, thereby improving the stability of the coupling after installation.

[0031] The working principle of the above embodiment is:

[0032] This coupling can be used in transmission machinery to firmly connect the driving shaft and the driven shaft and rotate them together. The specific operation is to first align the sealing block 3 on the right coupling 2 with the sealing groove 4 on the left coupling 1, and then insert the sealing block 3 into the sealing groove 4. At this time, the four limit plates 8 on the right coupling 2 respectively enter and exit the four boxes 5 on the left coupling 1, and extend to the limit grooves opened on the limit seat 9. Then, the threaded rod 601 is rotated by the handle 607. The rotation of the threaded rod 601 can drive the two movable blocks 602 on the outer surface of the threaded rod 601 to move to the opposite side, and push the hinged rod 605 to push the two movable blocks 602 to the opposite side. The movable limit block 606 moves downward until the limit block 606 is inserted into the slot provided on the limit plate 8, and finally the nut 608 is rotated so that the nut 608 is tightly fitted with the top of the left side of the box body 5, and the installation process of the coupling is completed. When the coupling needs to be disassembled for maintenance, the threaded rod 601 can be rotated in the opposite direction. At this time, the two movable blocks 602 on the threaded rod 601 move to the opposite side. At this time, the limit block 606 can be pulled out of the slot through the hinged rod 605 to complete the disassembly process. The operation is simple and convenient, and can effectively improve work efficiency. In addition, it is convenient for subsequent maintenance work on the coupling.

[0033] It can be understood that the control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
