Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figures 1 to 3 As shown, a pin cover for a cone crusher includes a pin cover body, which includes a cover 2 and a retaining ring 3. The retaining ring 3 has a first through hole 31 for limiting and abutting against the cover 2, and a stepped portion 32 for limiting and abutting the cover 2 is also provided between the retaining ring 3 and the first through hole 31. An annular limiting part 21 is provided around the outer wall of the cover 2. The annular limiting part 21 is engaged with the stepped part 32 of the retaining ring 3 to combine and install the cover 2 and the retaining ring 3.

[0017] By adopting the above structure, the previous method of constructing a single pin cover body from a single piece of steel through cutting, sawing, and grinding is transformed into assembling two parts together. This facilitates the processing of the pin cover body, with each part forming an independent production line. There is no need for complex cutting, sawing, and grinding on the same piece of steel, making processing more convenient. At the same time, the stepped part 32 on the retaining ring 3 and the annular limiting part 21 on the cover 2 can be quickly assembled and fixed. Furthermore, if the pin cover body is damaged or deformed and needs to be replaced, it is not necessary to replace the entire pin cover body. Only the damaged or deformed part needs to be replaced, saving materials and preventing the waste of excess steel.

[0018] Specifically, such as Figures 1 to 3 As shown, the stepped portion 32 has a first limiting sidewall 41, and the annular limiting portion 21 has a second limiting sidewall 51. The first limiting sidewall 41 and the second limiting sidewall 51 limit and abut against each other.

[0019] like Figures 1 to 3 As shown, the step portion 32 also has a first limiting bottom wall 42, and the annular limiting portion 21 has a second limiting bottom wall 52. The first limiting bottom wall 42 and the second limiting bottom wall 52 limit and abut against each other.

[0020] With the above structure, the first limiting sidewall 41 and the second limiting sidewall 51 limit each other, and the first limiting sidewall 41 and the second limiting sidewall 51 limit each other, which facilitates the quick assembly of the retaining ring 3 and the cover 2 together, and the limiting fixation is more reliable.

[0021] like Figures 1 to 3 As shown, the retaining ring 3 is centered on the first through hole 31 and surrounded by several connecting holes 6 for fixing the retaining ring 3 to the crusher hole, and is fixed by a connector. By providing the connecting holes 6, it is easier to further fix the pin cover body to the crusher hole through the connector, making the fixation more secure and the fixing effect better.

[0022] like Figures 1 to 3 As shown, the inner diameter formed by the stepped portion 32 and the center of the first through hole 31 is larger than the inner diameter of the first through hole 31.

[0023] like Figures 1 to 3 As shown, the bottom of the retaining ring 3 also has a chamfer 7. By setting the chamfer 7, it is easier for the retaining ring 3 to pass through the first through hole 31 of the cover 2 and be assembled with the cover 2, which facilitates assembly.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
