Once the bolt is forgotten, the door is easy to be opened, and the anti-theft effect will not be achieved at this time; at the same time, there is a certain gap between the two doors, and thieves are easy to use some means to open the bolt. . There are also some door bolts with complex production process, many operations, high production cost and complex structure.

【Content of invention】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a door bolt which is easy to use, has good anti-theft performance and low production cost.

The purpose of this utility model is achieved in that:

A bolt, comprising a bolt seat, is characterized in that a sliding bolt assembly is installed in the bolt seat, and a pushing mechanism capable of pushing the sliding bolt assembly to slide in the bolt seat is installed on the lower part of the sliding bolt assembly, and the pushing mechanism includes The longitudinal push rod and the horizontal push block, the horizontal push block is fixed on the bolt seat by the pin shaft, and the horizontal push block can rotate around the pin shaft; one side of the horizontal push block protrudes out of the bolt seat, and a The other end of the push rod is movably connected with the longitudinal push rod, and the other end of the longitudinal push rod is provided with a roller, which is in contact with the bottom of the slide block.

A deadbolt as described above is characterized in that the sliding bolt assembly is composed of a bolt, a slider and a return spring, the bolt is connected with the slider, the return spring is mounted on the bolt, and one end of the bolt is stuck on the slider, The other end is stuck on the bolt seat.

A door bolt as described above is characterized in that the door bolt includes an intermediate shaft connected with the slide plate, a compression spring is covered on the intermediate shaft, and a bolt sleeve is covered on the other end of the intermediate shaft.

A door bolt as described above is characterized in that a sliding groove is provided in the middle of the bolt seat, and the sliding door bolt assembly is installed in the sliding groove.

The beneficial effects of the utility model are: simple structure, labor-saving when bolting the door, convenient operation, and when closing the door, the horizontal push rod can be rotated by the force of the door to be closed to achieve that the bolt post can be automatically inserted into the bolt post hole of the door frame after the door is closed Inside; and the utility model is safe and anti-theft, and easy to install.

【Detailed ways】

A bolt includes a bolt seat 1, a sliding bolt assembly 2 is installed in the bolt seat 1, and a push mechanism 3 capable of pushing the sliding bolt assembly 2 to slide in the bolt seat is installed at the lower part of the sliding bolt assembly 2.

The middle of the bolt seat 1 is provided with a chute 4, the upper end of the chute 4 is provided with a bolt column fixing hole 5, and the bottom is provided with a push mechanism installation hole 6, the sliding door bolt assembly 2 is installed in the chute 4, and the push mechanism 3 is installed. In the installation hole 6 of the pushing mechanism.

Sliding bolt assembly 2 is made up of bolt 7, slide block 8, back-moving spring 9, and bolt 7 is connected with slide block 8, and bolt 7 penetrates bolt column fixing hole 5, and back-moving spring 9 is contained on the bolt 7, and its One end is stuck on the slide block 8, and the other end is stuck on the bolt seat 1. When the sliding door bolt assembly 2 is installed in the chute 4, since the slider 8 can be pushed by the pushing mechanism 3, the door bolt 7 can be stretched out and inserted into the bolt sleeve hole installed on the door frame, or under the action of the return spring 9 Retract down, so that the automatic door bolt has two states: bolted door and unbolted door.

The pushing mechanism 3 is at the bottom of the slide block 8, and it pushes the slide block 8 to slide in the chute 4. The pushing mechanism 3 includes a longitudinal pushing rod 10 and a transverse pushing block 11 . The horizontal pushing block 11 is fixed on the bolt seat 1 by the pin shaft 12, and the horizontal pushing block 11 can rotate around the pin shaft 12; Push rod 14 is arranged, and the other end of push rod 14 is flexibly connected with longitudinal push rod 10, and the other end of longitudinal push rod 10 is provided with roller 15, and roller 15 can roll in chute 4, and contacts with the bottom of slide block 8. The lower end of the push rod 11 is also provided with a limit shaft 16 at the column seat. When the slide block 8 resets under the action of the back-moving spring 9, the limit shaft 16 can be pushed against the rear end of the push rod 11, so that the longitudinal push rod 10 is aligned with the The push rod 14 remains formed in a "human" shape. When the external force pushes one side 13 of the horizontal push rod 11, the horizontal push rod 11 rotates around the pin shaft 12, and the push rod 14 pushes the longitudinal push block 10 to move to the upper end of the chute 4, and the roller 15 pushes the slide block 8 to the chute The upper end of 4 moves, and also just makes vertical push rod 10 and push rod 14 be in line, thereby makes slide bolt assembly 2 play a role.

The door bolt 7 includes an intermediate shaft 20 connected with the slide plate 8 , a compression spring 21 is sleeved on the intermediate shaft 20 , and a bolt sleeve 22 is sleeved on the other end of the intermediate shaft 20 .
