Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Embodiment 1 this embodiment provides a different motor shaft for door lock, as shown in fig. 1 to 4, including a special-shaped lock shaft 1, an arc-shaped outer arc groove 1a is formed at a head position of the special-shaped lock shaft 1, a key groove 1b for placing a flat key 2 is formed at a groove bottom of a middle portion of the outer arc groove 1a, a rotation hole 1c extending into the special-shaped lock shaft 1 is formed at a head end of the special-shaped lock shaft 1, a pair of rotation cores 11 are rotatably connected to the rotation hole 1c, adjusting blocks 12 are symmetrically arranged in the outer arc groove 1a, the two adjusting blocks 12 are respectively connected to the two rotation cores 11 through fixing bolts 121, swing grooves 1d communicated with the rotation hole 1c are symmetrically formed at centers of the left and right side groove bottoms of the outer arc groove 1a, the fixing bolts 121 pass through the swing grooves 1d, when the fixing bolts 121 are unscrewed, the two adjusting blocks 12 are slid in the outer arc groove 1a and drive the rotation cores 11 to rotate in the rotation holes 1c through the fixing bolts 121 After the end parts of the two adjusting blocks 12 are respectively abutted against the side end surfaces of the flat keys 2, the rotating core 11 and the adjusting blocks 12 can be clamped and fixed at the head part of the special-shaped lock shaft 1 by screwing the fixing bolt 121, so that the flat keys 2 can be fixed by the adjusting blocks 12, and the purpose of clamping the flat keys 2 of different types is achieved. The end block 13 is tightly welded at the head end of the special-shaped lock shaft 1, and the end block 13 blocks the rotary core 11 in the rotary hole 1c to prevent the rotary core 11 from falling off.
In this embodiment, the adjusting block 12 is in an arc structure and is slidably connected to the outer arc groove 1a, and the outer surface of the adjusting block 12 is flush with the circumferential surface of the special-shaped lock shaft 1, so that the special-shaped lock shaft 1 can drive the adjusting block 12 to rotate together in the shaft hole.
Specifically, the arc length of the outer arc groove 1a is greater than the sum of the arc lengths of the two adjusting blocks 12, so that the adjusting blocks 12 can be adjusted to different positions, and the flat keys 2 of different models can be conveniently adapted.
Further, the bottom of the key groove 1b is planar, so that the bottom surface of the flat key 2 can be attached to the bottom of the key groove 1b, and the adjusting block 12 can be abutted to the side surface of the flat key 2 conveniently.
In addition, the cross section of the swing groove 1d is fan-shaped, when the adjusting block 12 is pulled, the adjusting block 12 drives the rotating core 11 to rotate through the fixing bolt 121, and the swing groove 1d keeps away from the swing of the fixing bolt 121.
It should be noted that the edge of the outer end of the end block 13 is arc-shaped, so that the end block 13 with arc-shaped edge can play a guiding role when the special-shaped lock shaft 1 is installed.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
