The invention discloses a structure for preventing a U-shaped lock from being inserted reversely, and relates to the technical field of U-shaped locks, the structure comprises a lock body and a lock rod, a key hole is formed in the end face of the lock body, a first lock rod hole and a second lock rod hole are formed in the two sides of the key hole respectively, and a first protruding part and a second protruding part are arranged on the inner wall of the first lock rod hole and the inner wall of the second lock rod hole respectively; the first protruding part is located on the inner wall of the upper side of the first lock rod hole and arranged at a deflection angle relative to the center connecting line of the first lock rod hole and the second lock rod hole, and the second protruding part is located on the inner wall of the lower side of the second lock rod hole and arranged at the diagonal position of the first protruding part. The shape of the bottom end face of the first rod foot and the shape of the bottom end face of the second rod foot are consistent with the shape of the first rod locking hole and the shape of the second rod locking hole respectively, grooves are formed in the outer side wall of the first rod foot and the outer side wall of the second rod foot respectively, and the grooves are correspondingly embedded into the first protruding part and the second protruding part respectively. The U-shaped lock can be prevented from being inserted reversely, the overall manufacturing cost is low, and the structure is simple.
本发明公开了一种防止U型锁插反的结构，涉及U型锁技术领域，包括锁体和锁杆，锁体的端面设有钥匙孔，钥匙孔的两侧分别设有第一锁杆孔和第二锁杆孔，第一锁杆孔、第二锁杆孔的内壁分别设有第一凸起部、第二凸起部，第一凸起部位于第一锁杆孔的上侧内壁且相对于第一锁杆孔、第二锁杆孔的中心连线呈偏转角度设置，第二凸起部位于第二锁杆孔的下侧内壁且设置在第一凸起部的对角处，锁杆包括第一杆脚和第二杆脚，第一杆脚和第二杆脚的底部端面形状分别与第一锁杆孔和第二锁杆孔的形状一致，第一杆脚、第二杆脚的外侧壁上分别设置有凹槽，凹槽分别与第一凸起部、第二凸起部对应嵌合设置。本发明能够防止U型锁插反，且整体制造成本低、结构简单。
