Description

Technical Field

[0001] This utility model relates to the field of metal shaft technology, specifically a deformation-resistant metal shaft with a reinforced structure. Background Technology

[0002] A rotating shaft, as the name suggests, is a shaft that is essential for connecting the main components of a product and is used to withstand both bending moment and torque during rotation. Rotating shafts include both drive shafts and stirring shafts. When in use, the stirring shaft needs to drive the stirring blades to stir the material. The stirring blades will encounter resistance from the material when stirring it, and this resistance will ultimately act on the stirring shaft.

[0003] The stirring shaft needs to be connected to the connecting rod on the transmission structure. Existing connection methods are mostly threaded connections or connecting the two together with a clamp. Threaded connections are prone to loosening during use, while connecting with a clamp requires inserting the clamp into the stirring shaft and the connecting rod. However, during the stirring process, since the stirring shaft and the connecting rod are not a single piece and the forces on them are different, the connection part between the stirring shaft and the connecting rod is easily deformed, making it difficult to remove the stirring shaft later and preventing it from being reused.

[0004] Therefore, this utility model provides a deformation-resistant metal shaft with a reinforced structure to solve the above problems. Utility Model Content

[0006] This invention provides a deformation-resistant metal shaft with a reinforced structure, aiming to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A deformation-resistant metal shaft with a reinforced structure includes a metal shaft and a connecting rod. The bottom of the connecting rod has a groove and multiple positioning holes.

[0019] (III) Beneficial Effects

[0020] The use of positioning slots, positioning posts, grooves, and protrusions enhances the tightness between the metal shaft and the connecting rod.

This allows the force on the metal shaft to be fully transmitted to the connecting rod, preventing deformation at the connection point due to different forces. Furthermore, rotating the positive and negative threaded screws controls the movement of the insert blocks, thereby fixing the two arc-shaped clamps. Attached Figure Description

[0028] 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.

[0029] This utility model provides a deformation-resistant metal shaft with a reinforced structure, such as... Figures 1-5 As shown, the device includes a metal shaft 1 and a connecting rod 2. The bottom of the connecting rod 2 has a groove 3 and multiple positioning holes 4. The top of the metal shaft 1 is fixedly connected to a protrusion 22 and multiple positioning posts 8. Both the metal shaft 1 and the connecting rod 2 are fixedly connected to two fixing plates 5 and side plates 6. The side of the metal shaft 1 is provided with two arc-shaped clamping plates 9. The arc-shaped clamping plates 9 are composed of an arc-shaped plate and two horizontal plates, and the two horizontal plates are fixedly connected to one end of the arc-shaped plate. The arc-shaped clamping plates 9 are positioned to fit snugly against the metal shaft 1 and the connecting rod 2, clamping them together. The arc-shaped clamping plates 9 are provided with two openings 10. One of the arc-shaped clamping plates 9 has mounting plates 1 at both ends. 2. Two insert rods 13 are fixedly connected to one side of the mounting plate 12. The insert rods 13 are provided with slots 14. The other arc-shaped clamping plate 9 of the two arc-shaped clamping plates 9 is provided with annular plates 15 at both ends. The top and bottom of the annular plates 15 are arc-shaped, which matches the insert rods 13. The inner side of the annular plates 15 is provided with two sets of sliding grooves 16, and each set of sliding grooves 16 consists of two sliding grooves 16. Two sliding plates 17 are slidably connected inside the annular plates 15. Slider blocks 19 are fixedly connected to both sides of the sliding plates 17. A locking block 18 is fixedly connected to one side of the sliding plates 17. A partition plate 20 is fixedly connected inside the annular plates 15. A positive and negative threaded rod 21 is rotatably connected to the partition plate 20.

[0030] Multiple positioning holes 4 are evenly arranged around the groove 3. The groove 3 and positioning holes 4 correspond to the protrusion 22 and positioning post 8, respectively. The arrangement of the groove 3, positioning holes 4, protrusion 22 and positioning post 8 can enhance the tightness and integrity of the connection between the metal shaft 1 and the connecting rod 2, and facilitate the transmission of the force on the metal shaft 1 to the connecting rod 2, so that the forces on the two are as balanced as possible.

[0031] The two fixed plates 5 and the side plate 6 are symmetrically arranged, and the fixed plates 5 and the side plate 6 located on the metal shaft 1 and the connecting rod 2 are aligned vertically, with the side plate 6 located between the two fixed plates 5.

[0032] The top and bottom of the arc-shaped clamp 9 extend to a portion of the metal shaft 1 and the connecting rod 2, respectively. The through-hole 10 corresponds to the fixing plate 5. After the fixing plate 5 is inserted into the through-hole 10, the arc-shaped clamp 9, the metal shaft 1 and the connecting rod 2 can be connected to form a whole.

[0033] The side plate 6 is located between two arc-shaped clamps 9. The side plate 6 is provided with a first insertion hole 7. Both ends of the arc-shaped clamps 9 are provided with second insertion holes 11, and the second insertion holes 11 correspond to the first insertion hole 7.

[0034] One end of the insertion rod 13 passes through two No. 2 insertion holes 11 and No. 1 insertion hole 7 and extends out a portion. The insertion rod 13 can connect the two arc-shaped clamps 9 and the side plate 6 together, and the slots 14 are set opposite to each other.

[0035] The annular plate 15 is fitted onto the outer surface of the two insert rods 13, and the inner width of the annular plate 15 is the same as the diameter of the insert rods 13, and the inner height of the annular plate 15 is the same as the maximum distance between the two insert rods 13, thereby facilitating the installation of the annular plate 15.

[0036] Two sliding plates 17 are symmetrically arranged, slider 19 corresponds to slide groove 16, and locking block 18 corresponds to locking groove 14.

[0037] The partition 20 is located in the middle of the annular plate 15, and one end of the partition 20 and the two movable plates 17 extends out of the annular plate 15.

[0038] Both ends of the positive and negative threaded screw 21 pass through the partition plate 20 and the shift plate 17 and extend out a portion. The positive and negative threaded screw 21 and the shift plate 17 are threaded together. When the positive and negative threaded screw 21 rotates, the two shift plates 17 will move to the middle or both sides at the same time.

[0039] Specifically, first insert the protrusion 22 and positioning post 8 on the metal shaft 1 into the groove 3 and positioning hole 4 on the connecting rod 2, and align the fixing plate 5 and side plate 6 on the metal shaft 1 and connecting rod 2. Then place the two arc-shaped clamps 9 on the sides of the metal shaft 1 and connecting rod 2 and clamp them together. At this time, the fixing plate 5 on the metal shaft 1 and connecting rod 2 will be inserted into the through hole 10 on the arc-shaped clamp 9, while the side plate 6 is located between the two arc-shaped clamps 9.

[0040] Next, place the mounting plate 12 on one side of an arc-shaped clamping plate 9, and insert the insertion rod 13 into the second insertion hole 11 until it passes through the second insertion hole 11 on the other arc-shaped clamping plate 9. During this process, the insertion rod 13 will pass through the first insertion hole 7 on the side plate 6. Then, put the annular plate 15 on the two insertion rods 13 and push it towards the arc-shaped clamping plate 9 until the two are in contact. Finally, rotate the positive and negative threading screw 21 to move the two moving plates 17 outwards at the same time. The movement of the moving plates 17 will move the slider 19 and the locking block 18 until the locking block 18 is inserted into the locking plate on the insertion rod 13. The annular plate 15 is connected to the insert rod 13 within the groove 14. Similarly, another set of insert rods 13 and annular plates 15 are installed to fix the two arc-shaped clamps 9, thereby clamping the metal shaft 1 and the connecting rod 2, making them a whole. Therefore, when the metal shaft 1 is subjected to external force, it will be transmitted to the connecting rod 2 simultaneously, preventing the two from twisting and deforming due to different forces, which would affect the use. Moreover, since the positive and negative threaded screws 21 and the metal shaft 1 are set in parallel, even if the metal shaft 1 rotates, there is no need to worry about the positive and negative threaded screws 21 rotating, causing the moving plate 17 to shift.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
