Description

Technical Field

[0001] This utility model relates to the field of long shaft technology, and in particular to a segmented long shaft connection structure. Background Technology

[0002] Long shafts are widely used in mechanical transmissions, rotary supports, and power transmission, typically to bear large axial or radial loads and maintain the coaxiality of motion systems. In complex or large mechanical equipment, to facilitate transportation, installation, and subsequent maintenance, long shafts are often segmented, with multiple interconnected segments forming a complete transmission structure. Segmented long shafts maintain transmission stability while offering good disassembly and replacement flexibility, making them suitable for applications with limited space or requiring segmented manufacturing.

[0003] Existing segmented long shaft connection structures in practical applications mostly employ bolt fastening, key connections, or welding to axially connect multiple shaft segments. While these connection methods can meet the requirements of torque transmission and structural stability to a certain extent, the installation process often involves complex positioning, alignment, and fastening procedures, which not only increases operation time but also places higher demands on the technical skills of operators. Especially in working conditions with limited space or requiring frequent disassembly and assembly, traditional connection methods suffer from low assembly efficiency. Therefore, a segmented long shaft connection structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a segmented long shaft connection structure, which aims to improve the problem of low assembly efficiency in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The segmented long shaft connection structure includes,

[0007] Shaft 1 and Shaft 2 are joined together to form a complete long shaft structure;

[0008] Connecting ring one and connecting ring two are respectively connected to shaft one and shaft two;

[0009] Multiple retaining plates are disposed at the bottom of the second connecting ring, and each retaining plate has a cavity inside;

[0010] A locking block is inserted into the cavity and can slide within the cavity;

[0011] A spring, located within the cavity and supported below the locking block, provides an upward elastic force to the locking block;

[0012] The connecting ring has a groove inside, and the retaining plate can be inserted into the groove.

[0013] The slide groove is provided with a slot, and the locking block can enter the slot and engage with it during the twisting insertion process.

[0014] As a further description of the above technical solution:

[0015] One side of the card block is arc-shaped. During the twisting process, the arc-shaped side cooperates with the inner wall of the cavity to form a guide, so that the card block slides into the cavity after being squeezed.

[0016] As a further description of the above technical solution:

[0017] The slot is connected to the slide, and the block is reset under the action of the spring and locked inside the slot.

[0018] As a further description of the above technical solution:

[0019] The number of the card plates and slides is multiple, and they are distributed in a ring at the bottom of the second connecting ring and the inner side of the first connecting ring.

[0020] As a further description of the above technical solution:

[0021] One end of the spring is fixedly connected to the inside of the cavity, and the other end of the spring is fixedly connected to the bottom of the block.

[0022] As a further description of the above technical solution:

[0023] The card plate is L-shaped, and its sidewalls are slidably connected inside the groove.

[0024] This utility model has the following beneficial effects:

[0025] In this invention, the connection can be completed by the insertion structure of the card plate and the slide groove, combined with the rotation action, eliminating the traditional bolt connection or welding steps and improving installation efficiency. At the same time, the card block automatically slides into the card groove during rotation and completes self-locking under the action of spring force, effectively preventing the connection from loosening and improving the stability and safety of the overall structure. In addition, the multiple card plates and slide grooves are distributed in a ring, so that the long shaft connection is evenly stressed, effectively improving the load-bearing capacity and anti-torsional and anti-bending performance. Through the cooperation between the above structures, the reliability and practicality of the connection are improved. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5This utility model provides an embodiment of a segmented long shaft connection structure, including a shaft body 1 and a shaft body 2, which are spliced ​​together to form a complete long shaft structure; a connecting ring 3 and a connecting ring 4, which are respectively connected to the shaft body 1 and the shaft body 2; multiple locking plates 5, which are located at the bottom of the connecting ring 4, and the locking plates 5 have cavities 6 inside for installing locking components; locking blocks 7, which are inserted into the cavities 6 and can slide in the cavities 6 to achieve locking and releasing functions; springs 8, which are located in the cavities 6 and supported below the locking blocks 7, are used to provide upward elastic force to the locking blocks 7, which helps the locking blocks 7 to automatically reset after release, ensuring the stability and reliability of the connection state; a sliding groove 9 is provided inside the connecting ring 3, and the locking plates 5 can be inserted into the sliding groove 9 to achieve initial docking; a locking slot 10 is provided inside the sliding groove 9, and the locking blocks 7 can enter the locking slot during the twisting insertion process. 10 engages with it. One side of the locking block 7 is arc-shaped. During the twisting process, the arc-shaped side cooperates with the inner wall of the cavity 6 to form a guide, so that the locking block 7 slides into the cavity 6 after being squeezed. When the locking plate 5 rotates, the locking block 7 is pressed into the cavity 6, compressing the spring 8. After the locking block 7 is aligned with the position of the locking groove 10, the spring 8 releases energy to lift it up and lock it into the locking groove 10, completing the secure locking. The locking groove 10 is connected to the sliding groove 9. The locking block 7 is reset under the action of the spring 8 and locked in the locking groove 10. There are multiple locking plates 5 and sliding grooves 9, which are distributed in a ring at the bottom of the connecting ring 2 4 and the inner side of the connecting ring 1 3. One end of the spring 8 is fixedly connected to the inside of the cavity 6, and the other end of the spring 8 is fixedly connected to the bottom of the locking block 7 to ensure stable force and timely response. The locking plate 5 is L-shaped, and the side wall of the locking plate 5 is slidably connected to the inside of the sliding groove 9.

[0035] Working principle: When splicing shaft 1 and shaft 2, multiple locking plates 5 on connecting ring 2 4 are inserted into the sliding groove 9 in connecting ring 1 3 to achieve initial docking. Then, through rotation, the arc-shaped locking block 7 in the locking plate 5 is pressed down by the inner wall of the sliding groove 9 during rotation and compresses the spring 8. When the locking block 7 is aligned with the locking groove 10 in the sliding groove 9, the spring 8 releases its elastic force to push the locking block 7 into the locking groove 10, achieving self-locking and fixing, thereby completing the stable connection between the shafts.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
