Description

Technical Field

[0001] The utility model relates to the technical field of scroll spring mechanisms, in particular to a scroll spring mechanism with a fixing mechanism. Background Art

[0002] A spiral spring, also known as a clockwork spring, is a spring with one end fixed and the other end acting on a torque. Under the action of the torque, the spring material undergoes bending elastic deformation, causing the spring to twist in a plane, and the size of the deformation angle is proportional to the torque.

[0003] The existing volute spring mechanism is usually connected to other objects and installed by bolts, and the use of bolts requires a thread groove that is compatible with them. Therefore, when installing or removing the volute spring mechanism, the assistance of external tools is required. At the same time, if the bolt is rotated too many times, the thread groove will be damaged, and it is difficult to effectively ensure the stability of the volute spring mechanism during rotation. Therefore, the fixed connection method of the existing volute spring mechanism is inconvenient. For this reason, we provide a volute spring mechanism with a fixing mechanism. Utility Model Content

[0004] The purpose of the utility model is to solve the disadvantage in the prior art that the fixed connection between the scroll spring mechanism and other objects is inconvenient, and to provide a scroll spring mechanism with a fixing mechanism.

[0006] As a preferred embodiment, a scroll spring mechanism body is provided on one side of the shell, and a connecting plate is fixedly connected to the side of the scroll spring mechanism body away from the shell, and the scroll spring mechanism body and the connecting plate both pass through the outer surface of the rotating shaft, and the scroll spring mechanism body and the connecting plate are both rotatably connected to the rotating shaft.

[0007] As a preferred embodiment, a locking mechanism is provided on one side of the shell, and the number of the locking mechanisms is two. The locking mechanism includes a sliding rod, and the sliding rod is fixedly connected to the outer surface of the connecting plate. A locking groove is provided on the sliding rod, and a semicircular block is provided inside the fixed block.

[0008] As a preferred embodiment, one end of the semicircular block is fixedly connected to a connecting column, one end of the connecting column away from the semicircular block is fixedly connected to a compression spring, and one end of the compression spring away from the connecting column is fixedly connected to the inner wall of the fixed block.

[0009] As a preferred implementation, a sliding block is fixedly connected to the outer surface of the connecting column, and the sliding block passes through the interior of the fixing block.

[0010] As a preferred implementation, the sliding block is slidably connected to the fixed block, and one end of the sliding block away from the connecting column is fixedly connected to the adjusting block.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a scroll spring mechanism with a fixing mechanism, comprising: a mounting mechanism 1, the mounting mechanism 1 comprising a shell 11, a rotating shaft 12 is provided on one side of the shell 11, the rotating shaft 12 is fixedly connected to the shell 11, a scroll spring mechanism body 13 is provided on one side of the shell 11, a connecting disk 14 is fixedly connected to the side of the scroll spring mechanism body 13 away from the shell 11, the scroll spring mechanism body 13 and the connecting disk 14 both penetrate the outer surface of the rotating shaft 12, the scroll spring mechanism body 13 and the connecting disk 14 are both rotatably connected to the rotating shaft 12, a fixing ring 15 is fixedly connected to the outer surface of the shell 11, a limiting block 16 is provided in the limiting groove opened in the fixing ring 15, the number of the limiting blocks 16 is two, an arc block 17 is fixedly connected to the outer surface of the limiting block 16, and a fixing block 18 is fixedly connected to the side of the arc block 17 away from the limiting block 16.

[0026] In this embodiment, by providing the mounting mechanism 1, it is ensured that after the volute spring mechanism body 13 and the connecting plate 14 are fixed, the use principle of the volute spring mechanism body 13 is not changed, and thus the volute spring mechanism body 13 will always be used to rotate around the rotating shaft 12. In addition, in order to increase the service life of the volute spring mechanism body 13 and reduce the wear caused by the rotation of the volute spring mechanism body 13 and the rotating shaft 12, a limit block 16 is provided inside the fixing ring 15, and the limit block 16 can be driven to rotate in the limit groove opened inside the fixing ring 15, so as to cooperate with the use of the arc block 17 and the fixing block 18, so as to pull the rotation of the volute spring mechanism body 13, and the volute spring mechanism body 13 can rotate around the rotating shaft 12 without continuous contact and friction with the rotating shaft 12, so that the frequency of removal and replacement of the volute spring mechanism body 13 is reduced.

[0027] Example 2

[0028] like Figure 1-Figure 5 As shown, a locking mechanism 2 is provided on one side of the housing 11, and the number of the locking mechanisms 2 is two. The locking mechanism 2 includes a slide rod 21, which is fixedly connected to the outer surface of the connecting disk 14. A slot 22 is provided on the slide rod 21. A semicircular block 23 is provided inside the fixed block 18. A connecting column 24 is fixedly connected to one end of the semicircular block 23. A compression spring 25 is fixedly connected to the end of the connecting column 24 away from the semicircular block 23. The end of the compression spring 25 away from the connecting column 24 is fixedly connected to the inner wall of the fixed block 18. A slider 26 is fixedly connected to the outer surface of the connecting column 24. The slider 26 runs through the interior of the fixed block 18, and the slider 26 is slidably connected to the fixed block 18. An adjusting block 27 is fixedly connected to the end of the slider 26 away from the connecting column 24.

[0029] In this embodiment, by setting the locking mechanism 2, the spiral spring mechanism body 13 and the connecting disk 14 can be quickly fixed. By utilizing the connection between the slide rod 21 and the fixing block 18, the spiral spring mechanism body 13 and the connecting disk 14 can be stably installed. By setting the compression spring 25, when the compression spring 25 is squeezed by the connecting column 24, elastic force will be generated. Under the action of the elastic force of the compression spring 25, the semicircular block 23 in the locking mechanism 2 will automatically lock with the slot 22 opened on the slide rod 21. While ensuring a stable connection, the efficiency of the connection is improved, and the convenience of installing the spiral spring mechanism body 13 is thereby improved. In addition, a slider 26 and an adjusting block 27 are provided, and the adjusting block 27 can be slightly slid externally to release the locking connection between the slide rod 21 and the semicircular block 23, thereby achieving the purpose of quickly removing the spiral spring mechanism body 13.

[0030] Working principle:

[0031] like Figure 1-Figure 5As shown, when the utility model is in use, the connecting plate 14 and the scroll spring mechanism body 13 can be connected to the rotating shaft 12 first, and when connecting, pay attention to the position of the sliding rod 21 and the fixing block 18 to ensure that the two sliding rods 21 and the two fixing blocks 18 can fit together at the same time. When the sliding rod 21 enters the interior of the fixing block 18, the sliding rod 21 will first squeeze the semicircular block 23 into the interior of the fixing block 18, and then the semicircular block 23 will compress the compression spring 25 through the connecting column 24, so that the compression spring 25 generates elastic force. At this time, the elastic force of the compression spring 25 is not released. When the sliding rod 21 contacts the inner wall of the fixing block 18, the elastic force of the compression spring 25 is instantly released, resetting the connecting column 24 and the semicircular block 23, and finally rebounding the semicircular block 23 to the sliding rod 21, and most of the semicircular block 23 is engaged with the slot opened on the sliding rod 21. 22 fits together, and the scroll spring mechanism body 13 is quickly installed at this time. If the scroll spring mechanism body 13 is used, the scroll spring mechanism body 13 will rotate around the rotating shaft 12, and at the same time, under the connection of the fixed block 18 and the arc block 17, the limit block 16 will rotate within the limit opened inside the fixed ring 15, and then the rotation of the scroll spring mechanism body 13 and the rotating shaft 12 will not cause excessive contact at a certain position due to other reasons, thereby reducing the wear on the scroll spring mechanism body 13 and improving the service life. If the scroll spring mechanism body 13 needs to be removed, it is only necessary to slide the two adjusting blocks 27 at the same time, and use the slider 26 to drive the connecting column 24 and the semicircular block 23 to move in the opposite direction, until the semicircular block 23 is separated from the slide rod 21, and the scroll spring mechanism body 13 can be smoothly removed.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
