Abstract

The utility model relates to the field of a shaped bolt, and relates to a limiting bolt.

Description

Limiting bolt

Technical Field

The utility model relates to the field of shaped bolts, in particular to a limiting bolt.

Background

The latch is an anti-theft member for preventing a door or window from being opened from the outside. Modern door and window bolt devices are generally metal, while ancient door and window bolts are of wood structure. The bolt is generally divided into two parts, one part is provided with a movable rod, the other part is provided with a bolt hole, and the movable rod is inserted into the bolt hole for fixing.

However, in the actual use process, the bolt is easy to be bumped and bent by external force, and the movable rod cannot be inserted into the pin hole after being bumped and bent, so that the function is invalid. In addition, as the movable bolt rods in the market cannot be detached and replaced, the whole bolt assembly is required to be replaced, and the replacement cost is increased; if the bolt installed on the wooden door needs to be replaced, the bolt is fixed by the bolt, the bolt hole is reserved on the wooden door after the bolt is detached, and when the bolt is installed at the original position, the size of the bolt fixed by the replaced new bolt is larger than that of the bolt fixed before, otherwise, the fixing strength in the original bolt hole is reduced, and the bolt is easy to fall off; changing the fixing position of the bolt again is easy to limit in practical situations.

The technical scheme of the utility model is further described below with reference to the examples and the accompanying figures 1-3.

Example 1

A limit plug comprising: the fixing plate I1, the fixing plate II 2, the limit sleeve I3, the limit sleeve II 4 and the movable rod 5, screw holes 61 are formed in the fixing plate I1 and the fixing plate II 2, sliding grooves 62 are formed in the fixing plate I1 and the fixing plate II 2, the limit sleeve I3 is arranged in the sliding grooves 62 of the fixing plate I1 in a sliding mode, a first jack 71 communicated with the limit sleeve I3 is formed in the fixing plate I1, an inserting rod I72 is arranged in the first jack 71, the limit sleeve II 4 is arranged in the sliding grooves 62 of the fixing plate II 2 in a sliding mode, a second jack 73 communicated with the limit sleeve II 4 is formed in the fixing plate II 2, an inserting rod II 74 is arranged in the second jack 73, the movable rod 5 is arranged in the first limit sleeve I3 in a sliding mode, the right end of the movable rod 5 is arranged in the second limit sleeve II 4, and the lower end of the movable rod 5 is inserted into the inserting block 11 of the fixing plate I1.
