TOOTH ATTACHING/DETACHING STRUCTURE FOR BUCKET AND BUCKET
To provide a tooth attaching/detaching structure capable of preventing dropping and separation of the tooth from an adapter by abutting and locking a freely engaging recessed part of a slip-off preventive member to a protrusion of the adapter, and allowing easy removal and exchange of the tooth by releasing abutting and locking of the slip-off preventive member to the protrusion.SOLUTION: In a tooth attaching/detaching structure, an engaging and disengaging part 5 is formed to a tooth 3, an engaging and disengaging hole 5a with a stop end is formed to the engaging and disengaging part, an engaging and disengaging rod part 2a engageable/disengageable with the engaging and disengaging part is formed to an adapter 2, protrusions M1, M1 are formed on both side faces of the adapter, respectively, and an external force applied to the tooth is received by engagement contact of the engaging and disengaging hole of the tooth with the engaging and disengaging rod part of the adapter. Slip-off preventing mechanisms N, N that have slip-off preventive members 6, 6 preventing separation of the tooth from the adapter are provided on both sides of the engaging and disengaging part of the tooth. Freely engaging recessed parts N1, N1 engageable/disengageable with the protrusions of the adapter are formed to the slip-off preventive members, and the separation of the tooth from the adapter is prevented by abutting and locking of the freely engaging recessed parts with the protrusions.SELECTED DRAWING: Figure 1
【課題】アダプタの突起部に抜止部材の遊嵌凹部が当接係止することによりアダプタからのツースの抜け落ち離脱を阻止することができ、突起部に対する抜止部材の当接係止を解除することによりツースの取替交換を容易に行うことができる。【解決手段】ツース３に嵌脱部５が形成され、嵌脱部に先止まり穴状の嵌脱穴５ａが形成され、アダプタ２に嵌脱穴に嵌脱可能な嵌脱杆部２ａが形成され、アダプタの両側面にそれぞれ突起部Ｍ１・Ｍ１が形成され、ツースに加わる外力はツースの嵌脱穴とアダプタの嵌脱杆部との嵌合接触で受ける構造とされ、ツースの嵌脱部の両側部にアダプタからのツースの離脱を阻止する抜止部材６・６を有する抜止機構Ｎ・Ｎが設けられ、抜止部材に上記アダプタの突起部に嵌脱可能な遊嵌凹部Ｎ１・Ｎ１が形成され、遊嵌凹部と突起部との当接係止によりアダプタからのツースの離脱を阻止するように構成してなる。【選択図】図１
