Abstract

The invention belongs to the technical field of bolts, and particularly relates to a safety bolt which comprises a bolt rod and a bolt box, wherein the bolt rod penetrates in the bolt box; the bolt box comprises a bolt shell and a base; the bolt shell is divided into a reset cavity and a safety cavity by a partition plate; a baffle for preventing the bolt rod from sliding down from the safety box is fixed on the bolt rod and arranged in the reset cavity; the reset cavity is provided with a reset spring for resetting the bolt rod; a safety pin, a positioning spring and a spring positioning block are assembled in the safety cavity; the spring positioning block is fixed at the lower middle part of the safety pin; the lower end of the positioning spring is connected with the spring positioning block and sleeves the safety pin above the spring positioning block; the upper end of the safety pin penetrates out of the top of the safety cavity; a safety hole is formed in the bolt rod; the diameter of the safety hole is greater than the diameter of the safety pin. According to the safety bolt provided by the invention, the bolt rod slides toward the safety cavity so that the safety pin slides into the safety hole to realize self-locking of the bolt; automatic rebound of the bolt rod is realized through the reset spring by pulling out the safety pin.

Description

technical field [0001] The invention belongs to the technical field of bolts, in particular to a safety bolt. Background technique [0002] The latch is a simple part that prevents the door from opening. It is generally metal and consists of two parts, one with a movable rod and the other with a "nose". Usually the part with the rod is fixed on the door, the nose is fixed on the door frame, and the position should be corresponding. The structure is much simpler than that of the lock, but the effect is the same. It just locks the door outside and the latch is inside the door. When in use, just insert the rod into the nose. [0003] Existing bolts generally include a plunger and a manual lever. The plunger is generally cylindrical, and its front and rear ends are generally large. When in use, the rear end of the plunger generally slides into a matching bracket. The manual lever slides out of the bracket and cannot automatically pop out of the bracket, which is not convenien...
