DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0022] See also Figure 1 and Figure 2 As shown, the protective assembly between two components for rotational connection described in the utility model, wherein the two components include a first component and a second component 10, the first component 9 and the second component 10 are connected by a pin 11, in actual application, external impurities such as sand and dust can easily enter the flange of the connection, thereby causing more wear, and when subjected to external impact, it is easy to cause the connection to be damaged and unable to continue to be used, and the replacement and maintenance costs of the first component 9 and the second component 10 are high, which brings troubles to actual operation.

[0023] The protection assembly of the utility model comprises a clamp ring and a flange-shaped flange 12 fixedly arranged at the connection between the two components; the clamp ring is formed by a first protection member 1 and a second protection member 2 being detachably fixedly connected; Figure 1 and Figure 2 As shown, the ends of the first protective member 1 and the second protective member 2 are both provided with connecting members 4, which are connecting plates extending toward the outside and on which mounting holes are provided, so that the first protective member 1 and the second protective member 2 can be detachably fixedly connected by bolt assemblies or similar components after being fitted together.

[0024] In some preferred embodiments, both the first protective member 1 and the second protective member 2 are arc-surface protective members, and a clamping ring formed by the first protective member 1 and the second protective member 2 fits the outer portion of the connection between the first component 9 and the second component 10 .

[0025] The clamping ring includes a first limiting component and a second limiting component.

[0026] like Figure 1 and Figure 2 As shown, the first limit assembly includes an annular convex track 3 arranged on the inner side of the snap ring, the annular convex track 3 is integrally formed with the inner side of the snap ring and arranged vertically; in some preferred solutions, the annular convex track 3 can be a continuous annular convex track 3 structure, and in some other preferred solutions, the annular convex track 3 can be composed of a plurality of intermittently arranged convex track structures. The annular convex track 3 is adjacent to the flange and arranged parallel to the flange; thus, after installation, the first protective member 1 or the second protective member 2 can be prevented from lateral displacement from one side to the other side.

[0027] The second limiting component is arranged on one side of the first limiting component on the clamping ring, and the second limiting component detachably and fixedly connects the clamping ring to one of the components. In a specific embodiment, the second limiting component includes a limiting hole 5 arranged on the first protective member 1 and / or the second protective member 2. Figure 1 As shown, the second limiting assembly includes a limiting hole 5 provided on the first protective member 1, and also includes a first clamping column (not shown) provided on the first member 9 or the second member 10, the first clamping column is arranged perpendicular to the surface of the first member 9 or the second member 10, and the limiting hole 5 is adapted to the first clamping column, so as to prevent the clamping ring from sliding relative to the surface of the first member 9 or the second member 10 after installation. In a further preferred solution, the second limiting assembly also includes a limiting groove 6 provided on the first protective member 1 and / or the second protective member 2, the limiting groove 6 opens toward the edge of the first protective member 1 or the second protective member 2, and also includes a second clamping column 8 provided on the first member 9 or the second member 10, as shown in FIG. Figure 1 As shown, the limiting groove 6 is also adapted to the second clamping column 8 on the first component 9 or the second component 10. The second clamping column 8 can be fixed to the surface of the first component 9 or the second component 10 by welding or other means. The second clamping column 8 is fixed in the limiting groove 6. As mentioned above, the annular convex rail 3 prevents the clasp from sliding horizontally to one side, and the limiting groove 6 structure effectively prevents the clasp from sliding horizontally to the other side, effectively ensuring the fixing of the clasp at the connection between the first component 9 and the second component 10, reducing wear. And further improved, the second limiting assembly also includes a limiting rib 7 arranged on the first protective member 1 and the second protective member 2, and also includes a limiting block arranged on the first component 9 or the second component 10. The limiting rib 7 corresponds to the limiting block, and the limiting rib 7 is arranged in parallel with the limiting groove 6, thereby further reducing circumferential sliding. In practical applications, the limiting holes 5, the limiting grooves 6, and the limiting ribs 7 are arranged at intervals and dispersedly, so that the force is dispersed circumferentially to improve durability.

[0028] As a further improvement to this embodiment, Figure 4 As shown, the first member 9 and the second member 10 are both provided with the flange-shaped flange 12 at the connection, and the two flanges at the connection of the first member 9 and the second member 10 are arranged in close contact. The diameter of the flange provided on the first member 9 is slightly larger than the diameter of the flange on the second member 10, and the second limit assembly detachably and fixedly connects the clamp ring to the first member 9, so that the main force-bearing part is on the first member 9, and the durability is higher. In this embodiment, the flange 12 is a high-strength wear-resistant flange structure.

[0029] like Figure 3In the specific application case shown, the first component 9 is the bucket arm, the second component 10 is the bucket, the first component 9 and the second component 10 are connected by a pin 11, and the connection is protected by the protection assembly described in the utility model. The first protection member 1 and the second protection member 2 are combined and sleeved on the outside of the connection. When the clamping ring is sleeved on the outside of the flange 12 at the connection between the first component 9 and the second component 10, the first limit assembly and the second limit assembly are respectively arranged on both sides of the flange 12. Figure 3 As shown, the snap ring is fixedly connected to the second member 10 through the second limit assembly, and the snap ring is simultaneously arranged in contact with the first member 9 through the annular convex rail 3, so that the first member 9 can still move around the second member 10. The width of the snap ring is required to at least cover the flange 12, thereby preventing the entry of external impurities such as sand and dust, effectively reducing wear and effectively improving durability. After wear occurs, there is no need to replace the connecting member of the bucket arm or bucket, which greatly saves production costs.
