Lock body

Abstract

The invention discloses a lock body with simple structure, low cost and greatly improved tensile strength. The lock body comprises a lock body shell and a lock body cylinder, wherein the lock body cylinder is combined by two cylinder bodies and installed in the lock body shell, both sides of the lock body cylinder are provided with lock ring holes respectively, the inner side of each lock ring hole is provided with a lock brake hole communicated with the lock ring hole, and a top surface reinforcing plate is arranged above each lock brake hole.

Description

technical field [0001] The invention relates to a lock body. Background technique [0002] The lock body in the prior art has an integral structure, and the lock body is generally integrally processed from a metal material with an integral structure. The structure is relatively tight, but the cost is relatively high due to complicated processing. In order to reduce the cost, there is a split structure. The lock body of the split structure generally includes a lock body shell and a lock inner core. The lock inner core is composed of two inner cores. The lock inner core is installed in the lock body shell. The two sides of the core in the lock body are respectively provided with lock ring holes, and the inner side of the lock ring hole is provided with a lock gate hole which communicates with the lock ring hole. The lock gate is installed in the lock gate hole, and the lock ring is sleeved in the lock ring hole. The lock body with body structure, because the lock body shell a...

[0002] The lock body in the prior art has a one-piece structure, and the lock body is generally processed from a metal material with an integral structure. The structure is relatively tight, but the cost is relatively high due to the complicated processing.

In order to reduce the cost, there is a split structure. The lock body of the split structure generally includes a lock body shell and a lock inner core. The lock inner core is composed of two inner cores. The lock inner core is installed in the lock body shell. The two sides of the core in the lock body are respectively provided with lock ring holes, and the inner side of the lock ring hole is provided with a lock gate hole which communicates with the lock ring hole. The lock gate is installed in the lock gate hole, and the lock ring is sleeved in the lock ring hole. The lock body with body structure, because the lock body shell and the lock inner core can be molded without processing, which greatly reduces the cost, but because the lock inner core is generally made of plastic, zinc alloy, aluminum alloy and other materials, the tensile test , when the lock ring drives the lock to move upward, the inner core of the lock generally cannot withstand the pressure of the lock and deforms, resulting in the failure of the tensile test, which in turn affects the quality of the finished product
