Description

Technical Field

[0001] This utility model relates to the field of grab bucket tooth sleeve technology, specifically a grab bucket tooth sleeve. Background Technology

[0002] The toothed sleeve of a grab bucket primarily serves to protect the grab's jaw plates and enhance its wear resistance. The toothed sleeve is typically made of high-strength, wear-resistant materials, effectively extending the grab's service life, reducing jaw plate damage caused by material wear, and thus lowering maintenance costs and downtime.

[0003] Existing grab bucket tooth sleeves are all fixedly connected by bolts and nuts. However, the grab bucket generates significant vibrations when opening and closing, as well as when grabbing objects. These vibrations are transmitted to the bolts and nuts, which may cause them to loosen, leading to the loosening and detachment of the tooth sleeves. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a grab bucket tooth sleeve, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a grab bucket tooth sleeve, including a sleeve body, a circular groove is opened at the top of the sleeve body, a hexagonal hole is opened at the bottom of the sleeve body, an annular groove is opened inside the circular groove, a fixed tooth ring is fixedly arranged above the inside of the annular groove, a movable tooth ring is meshed and connected inside the fixed tooth ring, and a hexagonal ring is fixed inside the movable tooth ring.

[0006] A bolt is fitted inside the hexagonal ring, and a nut is screwed onto the bottom end of the bolt through the sleeve. The nut is located inside the hexagonal hole. A movable magnetic ring is fixed inside the hexagonal ring, and a fixed magnetic ring is fixed on the lower inner surface of the circular groove.

[0007] Preferably, a gasket ring is integrally formed on the lower inner surface of the circular groove.

[0008] Preferably, the movable magnetic ring and the fixed magnetic ring repel each other.

[0009] Preferably, the top of the hexagonal ring has two rotating holes.

[0010] Preferably, the hexagonal ring has two limiting holes at its top, and a limiting rod is provided inside the limiting holes.

[0011] Preferably, the inner lower surface of the circular groove is rotatably connected to a rotating ring located outside the fixed magnetic ring, and the bottom of the limiting rod and the top of the rotating ring are fixedly connected.

[0012] Beneficial effects

[0013] This utility model provides a grab bucket tooth sleeve. Compared with the prior art, it has the following advantages:

[0014] This grab bucket tooth sleeve, by setting a fixed tooth ring, a movable tooth ring, a movable magnetic ring, a fixed magnetic ring, and a hexagonal ring, fits the sleeve body onto the grab bucket teeth. The nut is placed inside the hexagonal hole, and the bolt passes through the sleeve body and grab bucket teeth to be screwed onto the nut. Using a hexagonal wrench, inserted on the outside of the bolt, turning the hexagonal wrench will tighten the bolt and nut. Remove the hexagonal wrench, insert a tool into the hole, and turn the tool to align the movable tooth ring with the fixed tooth ring, and the hexagonal ring with the bolt. If the bolt and the hexagonal ring do not align, fine-tune the angle of the bolt to align them. In this way, the fixed magnetic ring and the movable magnetic ring repel each other, the hexagonal ring and the movable tooth ring move upward, and the movable tooth ring and the fixed tooth ring mesh and connect. This can restrict the rotation of the nut and bolt and prevent the connection from loosening. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4This utility model provides a technical solution: a grab bucket toothed sleeve, including a sleeve body 1, a circular groove 2 on the top of the sleeve body 1, a hexagonal hole 9 on the bottom of the sleeve body 1, an annular groove 8 inside the circular groove 2, a fixed toothed ring 4 inside the annular groove 8, a movable toothed ring 13 meshing inside the fixed toothed ring 4, a hexagonal ring 5 fixed inside the movable toothed ring 13, a bolt 3 sleeved inside the hexagonal ring 5, a nut 7 screwed to the bottom end of the bolt 3 through the sleeve body 1, the nut 7 being located inside the hexagonal hole 9, a movable magnetic ring 12 fixed inside the hexagonal ring 5, a fixed magnetic ring 11 fixed on the lower surface inside the circular groove 2, which can prevent the bolt 3 and the nut 7 from loosening, a washer 10 integrally formed on the lower surface inside the circular groove 2, which can restrict the bolt 3 from moving downwards, the movable magnetic ring 12 and the fixed magnetic ring 11 repel each other, which can push the movable toothed ring 13 and the hexagonal ring 5 upwards, and two rotating holes 6 on the top of the hexagonal ring 5 for easy adjustment.

[0022] Furthermore, the top of the hexagonal ring 5 has two limiting holes 14, and the inside of the limiting holes 14 is provided with a limiting rod 15. The lower inner surface of the circular groove 2 is rotatably connected to the outer side of the fixed magnetic ring 11, and the bottom of the limiting rod 15 and the top of the rotating ring 16 are fixedly connected, which can restrict the movement of the hexagonal ring 5.

[0023] During operation, sleeve 1 is fitted onto the grab teeth, nut 7 is placed inside hexagonal hole 9, bolt 3 passes through sleeve 1 and grab teeth, and is screwed onto nut 7. Using a hex wrench, insert it outside bolt 3 and push hexagonal ring 5 downward with the hex wrench. Then rotate the hex wrench to tighten bolt 3 and nut 7. Remove the hex wrench and insert a tool into rotating hole 6. Rotate the tool to rotate hexagonal ring 5 and moving gear ring 13. Moving gear ring 13 aligns with fixed gear ring 4, and hexagonal ring 5 aligns with bolt 3. If bolt 3 and hexagonal ring 5 do not align, fine-tune the angle of bolt 3 to align them. In this way, fixed magnetic ring 11 and moving magnetic ring 12 repel each other, hexagonal ring 5 and moving gear ring 13 move upward, and moving gear ring 13 engages with fixed gear ring 4. This can limit the rotation of nut 7 and bolt 3 and prevent the connection from loosening.
