Description

Technical Field

[0001] This utility model relates to the field of universal joint technology, specifically to a safety-type anti-drop universal joint head. Background Technology

[0002] Universal joints are one of the most commonly used types of couplings. Utilizing their structural characteristics, they enable two shafts that are not on the same axis, have a large angle between their axes, or experience significant axial movement to rotate continuously at the same angular velocity, reliably transmitting torque and motion. They are widely used in the mechanical shaft systems of hoisting, engineering transportation, mining, petroleum, shipbuilding, coal, rubber, papermaking machinery, and other heavy machinery industries for torque transmission.

[0003] During the production of high-speed wire rod, the universal joint of the rolling mill may easily detach from the mill due to vibrations and other factors during prolonged operation. This can cause the equipment to malfunction, affect production efficiency, and pose a safety hazard to the equipment and personnel.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] A safety-type anti-detachment universal joint head includes a universal joint and a joint head movably connected thereto. The end of the joint head away from the universal joint is connected to a machine body. The machine body is provided with an anti-detachment mechanism to prevent the joint head from detaching. The anti-detachment mechanism includes a connecting seat, which is connected to the machine body by bolts. The bottom of the connecting seat is movably connected to a first reinforcing block and a second reinforcing block sleeved on the joint head.

[0008] Preferably, the anti-detachment mechanism further includes a first half gear and a second half gear that are symmetrically and movably connected within the connecting seat. The bottoms of the first half gear and the second half gear are respectively connected to the first reinforcing block and the second reinforcing block, and the tops of the first half gear and the second half gear are provided with a transmission gear that meshes with them.

[0009] Preferably, the first transmission gear is movably connected to the connecting seat via a fixed shaft, the fixed shaft is provided with a driven gear, and the connecting seat is symmetrically provided with second transmission gears that mesh with the two sets of driven gears respectively.

[0010] Preferably, the transmission gear two is movably connected to the connecting seat via a rotating shaft, wherein a worm gear is sleeved on one of the rotating shafts, and a worm is provided on one side of the worm gear to mesh with it.

[0011] Preferably, the top of the worm gear extends to the outside of the connecting seat and is provided with a knob, and the knob is fitted with an anti-slip rubber ring.

[0012] Preferably, both the first reinforcing block and the second reinforcing block have reinforcing grooves on their adjacent sides, and the inner side of the reinforcing grooves is provided with rubber pads.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0021] According to an embodiment of the present invention, a safe anti-fall-off universal joint head is provided.

[0022] Example 1:

[0023] like Figure 1-3 As shown, the safety anti-detachment universal joint head according to an embodiment of the present utility model includes a universal joint 1 and a joint head 2 movably connected thereto. The end of the joint head 2 away from the universal joint 1 is connected to the machine body. The machine body is provided with an anti-detachment mechanism for preventing the joint head 2 from detaching. The anti-detachment mechanism includes a connecting seat 4. The connecting seat 4 is connected to the machine body by bolts. The bottom of the connecting seat 4 is movably connected to a first reinforcing block 5 and a second reinforcing block 6 sleeved on the joint head 2.

[0024] Example 2:

[0025] like Figure 1-3 As shown, the anti-detachment mechanism also includes a first half gear 7 and a second half gear 8 symmetrically and movably connected within the connecting seat 4. The bottoms of the first half gear 7 and the second half gear 8 are respectively connected to the first reinforcing block 5 and the second reinforcing block 6. The tops of the first half gear 7 and the second half gear 8 are provided with a first transmission gear 9 that meshes with them. The first transmission gear 9 is movably connected to the connecting seat 4 through a fixed shaft 10. A driven gear 11 is provided on the fixed shaft 10. The connecting seat 4 is symmetrically provided with two sets of driven gears 12 that mesh with the two sets of driven gears 11. The second transmission gear 12 is movably connected to the connecting seat 4 through a rotating shaft 13. A worm gear 14 is sleeved on one set of the rotating shaft 13. A worm 15 that meshes with the worm gear 14 is provided on one side of the worm gear 14.

[0026] Example 3:

[0027] like Figure 1-3 As shown, the top of the worm gear 15 extends to the outside of the connecting seat 4 and is provided with a knob 16. The knob 16 is fitted with an anti-slip rubber ring. The reinforcing block 1 5 and the reinforcing block 2 6 are both provided with a reinforcing groove 17 on their respective sides. The inner side of the reinforcing groove 17 is provided with a rubber pad.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, rotating the knob 16 drives the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 14, which in turn drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the transmission gear 12 to rotate, causing the two sets of transmission gears 12 to mesh and rotate synchronously, thereby driving the driven gear 11 to rotate. The driven gear 11 drives the transmission gear 9 to rotate through the fixed shaft 10. The transmission gear 9 meshes with the half gear 7 and the half gear 8, thereby driving the reinforcing block 5 and the reinforcing block 6 to rotate in the same direction. The locking and limiting between the reinforcing block 2 and the shaft head 2 can prevent the shaft head 2 from disengaging from the machine body when the universal joint 1 rotates.

[0030] In summary, by means of the above-mentioned technical solution of this utility model, through the setting of the shaft head 2 and the anti-detachment mechanism, and the locking and limiting between the reinforcing block 5 and the reinforcing block 6 and the shaft head 2, the connection between the shaft head 2 and the machine body can be prevented when the universal joint 1 rotates, so that the equipment can operate normally and stably, improve work efficiency, facilitate operation, and improve the safety of equipment and personnel during work.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
