The utility model further sets: one side of the positioning part is inclined inwardly to form a first positioning groove with one side of the first installation part, and the other side of the first installation part is provided with a first riveting notch, When the first lock tongue is sleeved on the first mounting part, one side of the first lock tongue is in contact with the opening end of the first positioning groove, and the other side is riveted and fixed in the first riveting recess. verbal.

The utility model further sets: the other side of the positioning part is also inclined inwardly to form a second positioning groove with one side of the second installation part, and the other side of the second installation part is provided with a second riveting recess When the second lock tongue is sleeved on the second installation part, one side of the second lock tongue is in conflict with the opening end of the second positioning groove, and the other side is riveted and fixed on the second Riveted on the notch.

The utility model further provides that: a guide groove is provided in the installation hole of the first lock bolt, and the guide groove is matched with the first installation part.

The beneficial effects of the utility model: because the first lock tongue is sleeved on the first installation part, one side of the first lock tongue is in conflict with the positioning part, and the other side is riveted on the first installation part; The second lock tongue is sleeved on the second installation part, one side of the second lock tongue is in conflict with the positioning part, and the other side is riveted on the second forehead installation part, and the positioning part can be aligned with the first lock. The installation and positioning of the tongue and the second bolt can prevent the installation of the first bolt and the second bolt from being offset, so that the first bolt and the second bolt can be installed separately, and the first bolt, the second bolt, and the second bolt can be lowered. The dimensional accuracy requirements of the bolt fixing piece are easy to assemble, and at the same time, it is also convenient to manufacture, which reduces the manufacturing cost. Moreover, the first bolt or the second bolt needs to be replaced, and it is not necessary to replace the first bolt and the second bolt at the same time, reducing the cost. The cost.

detailed description

A double deadbolt structure of the present invention will be further described in detail with reference to accompanying drawings 1 to 3 .

A double deadbolt structure, including a deadbolt fixing piece 1, a first deadbolt 2 and a second deadbolt 3, the deadbolt fixing piece 1 includes a fixing piece body 11 and first mounting parts 12 and second The installation part 13, a positioning part 14 is arranged between the first installation part 12 and the second installation part 13; the first lock tongue 2 is sleeved on the first installation part 12, and one side of the first lock tongue 2 One side conflicts with the positioning portion 14 , and the other side is riveted on the first mounting portion 12 .

One side of the positioning portion 14 is arranged to be inclined inwardly and form a first positioning groove 15 with one side of the first mounting portion 12, and the other side of the first mounting portion 12 is provided with a first riveting notch 121. When the first lock tongue 2 is sleeved on the first installation part 12, one side of the first lock tongue 2 is in conflict with the opening end of the first positioning groove 15, so that the first lock tongue 2 is in contact with the positioning The part 14 realizes point contact, avoiding the displacement of the first lock tongue 2 due to the assembly size of the positioning part 14, and the other side of the first lock tongue 2 is riveted and fixed on the first riveting notch 121 by a riveting machine. , to achieve rapid assembly.
