Abstract
Description

[0001] This utility model relates to the field of high-core torsion shaft technology, and in particular to a high-core torsion shaft. Background Technology
[0002] High-core torsion shafts are mechanical components used to transmit torque, commonly found in industrial equipment and drive systems. Compared to traditional torsion shafts, high-core torsion shafts offer higher strength, stiffness, and better fatigue resistance in their design and materials, enabling them to withstand higher load operating environments.
[0003] Currently, high-core torsion shafts are used in many places, including in extruders. However, existing high-core torsion shafts are generally a single unit, which makes installation and disassembly of integral torsion shafts very difficult in confined spaces or complex structures, and may even require the disassembly of other parts. At the same time, since current torsion shafts are manufactured within a limited length range, the length cannot be adjusted according to equipment or process requirements, resulting in torsion shafts that can only be used in specific equipment, thus limiting their versatility.

[0029] Example 1
[0030] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a high-core torsion shaft. The high-core torsion shaft includes a torsion shaft assembly 100 and a connecting assembly 200. The torsion shaft assembly 100 facilitates the adjustment of the length of the first torsion bar 101 and the second torsion bar 102, thereby allowing the length to be adjusted according to different equipment or process requirements and improving the versatility of the torsion shaft. The connecting assembly 200 facilitates the quick assembly between the first torsion bar 101 and the second torsion bar 102, so that when damaged, only one end needs to be replaced, without replacing the whole shaft, thus saving costs.
[0031] The torsion shaft assembly 100 includes a first torsion bar 101, a second torsion bar 102, a connecting shell 103, a movable column 104, and an adjusting member 105. The second torsion bar 102 is disposed on one side of the first torsion bar 101, the connecting shell 103 is disposed on one side of the first torsion bar 101, the movable column 104 is disposed inside the connecting shell 103, and the adjusting member 105 is disposed inside the connecting shell 103.
[0032] The first torsion bar 101 and the second torsion bar 102, together with the connecting shell 103, facilitate the adjustment of the length of use. The movable column 104 is slidably connected inside the connecting shell 103, and with the adjustment component 105, the length of the movable column 104 inside the connecting shell 103 can be adjusted to improve the flexibility of the torsion bar.
[0033] The connecting assembly 200 is disposed on one side of the first torsion bar 101 and includes a retaining post 201, a toothed groove 202, a mounting ring 203, and an anti-reverse component 204. The retaining post 201 is fixed to one side of the first torsion bar 101, the toothed groove 202 is formed on one side of the retaining post 201, the mounting ring 203 is disposed on one side of the retaining post 201, and the anti-reverse component 204 is disposed at the top and bottom of the mounting ring 203.
[0034] The mounting ring 203 can be fixed to the mounting post 201 by using the toothed groove 202. The anti-reverse component 204 can be used to help position the ring after installation and prevent the threads from loosening and reversing.
[0035] Example 2
[0036] Reference Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the toothed grooves 202 are arranged in a ring array on one side of the retaining post 201. The retaining post 201 has an internal thread design. The mounting ring 203 is fixedly connected to the connecting shell 103 through a connecting plate.
[0038] The toothed groove 202 is provided on one side of the retaining post 201, which facilitates its use with the anti-reverse component 204. The retaining post 201 has an internal thread design, which facilitates its use with the mounting ring 203.
[0039] Specifically, the connecting assembly 200 also includes a threaded rod 205 and a retaining groove 206. The threaded rod 205 is fixed to one side of the mounting ring 203 and its surface is threadedly connected to the retaining post 201. The retaining groove 206 is formed at the top and bottom of the mounting ring 203.
[0040] The threaded rod 205 is fixed to one side of the mounting ring 203 and cooperates with the thread in the retaining post 201, which facilitates the installation and fixation between the first torsion bar 101 and the second torsion bar 102. The retaining groove 206 facilitates the assembly of the anti-reverse component 204.
[0041] Specifically, the anti-reverse component 204 includes a spring 204a, a push plate 204b, and a locking block 204c. The spring 204a is fixed to one side inside the retaining groove 206, and one side is fixedly connected to the push plate 204b. The locking block 204c is fixed to one side of the push plate 204b, and its surface is engaged with the inside of the toothed groove 202.
[0042] Because the locking block 204c is designed at an angle, and as the mounting ring 203 rotates, when the locking block 204c is about to engage with the tooth groove 202, the locking block 204c will be frequently subjected to force, causing the push plate 204b to compress the spring 204a until the threaded rod 205 is completely screwed into the retaining post 201. Then, the locking block 204c will be engaged inside the last tooth groove 202, thereby preventing the threads from reversing and loosening, and ensuring the stability of use.
[0043] Specifically, the anti-reverse component 204 also includes a limiting rod 204d, which is fixed to one side inside the retaining groove 206 and its surface is slidably connected to the inside of the push plate 204b and the locking block 204c.
[0044] By sliding the limit rod 204d with the internal sliding connection of the locking block 204c and the push plate 204b, the stability of the push plate 204b and the locking block 204c during movement can be improved.
[0045] Specifically, the maximum stroke between the push plate 204b and the spring 204a is less than that of the limit rod 204d, and the push plate 204b is curved.
[0046] However, the elasticity of spring 204a in the figure is already at its maximum stroke, so the locking block 204c will not disengage from the outside of the limiting rod 204d. Therefore, the locking block 204c will move in a limited position on the surface of the limiting rod 204d, thereby ensuring the stability of the locking block 204c when it moves.
[0047] Specifically, the adjusting component 105 includes a rotating ring 105a, a limiting ring 105b, a lead screw 105c, a fixed ring 105d, and a guide ring 105e. The rotating ring 105a is rotatably connected to one side inside the fixed post 201. The limiting ring 105b is fixed inside the connecting shell 103. The lead screw 105c is fixed to one side of the rotating ring 105a, and the other side extends into the interior of the connecting shell 103 and is rotatably connected to the fixed ring 105d through a bearing. The interior of the guide ring 105e is rotatably connected to the surface of the lead screw 105c, and its surface is fixedly connected to the movable post 104.
[0048] By rotating the rotating ring 105a inside the fixed column 201, the lead screw 105c will rotate with the rotating ring 105a. At this time, the guide ring 105e will be forced to move on the surface of the lead screw 105c, and synchronously drive the movable column 104 and the second torsion bar 102 to move, thereby adjusting the length of use.
[0049] Example 3
[0050] Reference Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0051] Specifically, the adjusting component 105 also includes an anti-slip pad 105f, a limiting ring 105g, and a limiting groove 105h. The anti-slip pad 105f is fixed in a ring array on the surface of the rotating ring 105a, the limiting ring 105g is fixed on one side of the surface of the movable column 104, and the limiting groove 105h is opened inside the connecting shell 103.
[0052] By fixing the anti-slip pad 105f to the surface of the rotating ring 105a, the friction between the rotating ring 105a and the operator's fingers can be increased, making it easier for the operator to rotate the rotating ring 105a for adjustment. The limiting ring 105g, together with the limiting groove 105h, can limit the final stroke of the movable column 104 and prevent the movable column 104 from dislodging from the interior of the connecting shell 103.
[0053] Specifically, one side of the rotating ring 105a is T-shaped, and one side of the retaining post 201 is provided with a concave groove for cooperating with the rotation of the rotating ring 105a.
[0054] The rotating ring 105a is T-shaped at one end and forms a sliding limit with the groove inside the retaining post 201, which facilitates the limiting rotation of the rotating ring 105a.
[0055] Specifically, the adjusting member 105 also includes a slide rod 105i, which is fixed to one side of the limiting ring 105b and extends through to the outside of the guide ring 105e and is fixedly connected to the fixing ring 105d.
[0056] By fixing the slide rod 105i between the limiting ring 105b and the fixed ring 105d, the guide ring 105e can be limited to move in parallel, preventing the guide ring 105e from driving the second torsion bar 102 to rotate for adjustment.
[0057] In use, the user first moves the mounting ring 203 to drive the connecting shell 103, the movable column 104, and the second torsion bar 102. The threaded rod 205 at one end of the mounting ring 203 is then threaded into the threaded groove inside the retaining column 201 for installation and positioning. The locking block 204c is angled, and as the mounting ring 203 rotates, when the locking block 204c is about to engage with the toothed groove 202, it will frequently experience force, causing the push plate 204b to compress the spring 204a. This continues until the threaded rod 205 is fully screwed into the retaining column 201, at which point the locking block 204c will engage inside the last toothed groove 202. This prevents the threads from reversing and loosening, ensuring stability during use. After installation, if the user needs to adjust the working distance of the second torsion bar 102, the rotating ring 105a can be rotated inside the fixed column 201. At this time, the lead screw 105c will rotate with the rotating ring 105a. The guide ring 105e will be forced to move on the surface of the lead screw 105c. The guide ring 105e will also move to a limit on the surface of the slide bar 105i, and simultaneously drive the movable column 104 and the second torsion bar 102 to move and adjust the working length. Thus, the length can be adjusted according to different equipment or process requirements, improving the versatility of the torsion bar.
[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
