[0005] To achieve the above objectives, a miniature linear motor with a guide rail is provided, comprising:

[0006] A base has a stator fixedly connected to its upper surface, a guide rail on its upper surface, a slide block slidably connected to the outer surface of the guide rail, a mover fixedly connected to the lower surface of the slide block, a mounting plate fixedly connected to the upper surface of the slide block, a snap-fit ​​block fixedly connected to the lower surface of the guide rail, a first fixing plate fixedly connected to the lower surface of the base, a bidirectional threaded rod rotatably connected to the inner surface of the first fixing plate, a first limiting block fixedly connected to the left end of the bidirectional threaded rod, a second limiting block fixedly connected to the right end of the bidirectional threaded rod, a second fixing plate rotatably connected to the outer surface of the bidirectional threaded rod, a connecting seat threadedly connected to the outer surface of the bidirectional threaded rod, a fixing post fixedly connected to the inner surface of the connecting seat, a connecting strip rotatably connected to the outer surface of the fixing post, a connecting post rotatably connected to the inner surface of the connecting strip, a fixing seat fixedly connected to the outer surface of the connecting post, an insert block fixedly connected to the outer surface of the fixing seat, and a moving block fixedly connected to the upper surface of the connecting seat.

[0009] According to the aforementioned miniature linear motor with guide rail, the outer surface of the base is provided with a through groove, and the inner surface of the through groove is adapted to the snap-fit ​​block.

[0010] According to the aforementioned miniature linear motor with guide rail, the outer surface of the latch block is provided with a socket, and the inner surface of the socket is adapted to the latch block.

[0011] According to the aforementioned miniature linear motor with guide rail, the lower surface of the base is provided with a limiting groove, and the inner surface of the limiting groove is adapted to the moving block.

[0012] According to the aforementioned miniature linear motor with guide rail, the lower surface of the base is fixedly connected to the second fixing plate, and the number of connecting seats is two, distributed left and right.

The lower surface of the base 1 is provided with a limiting groove 27. The inner surface of the limiting groove 27 is adapted to the moving block 26 and is used to limit the movement of the insert block 18. The lower surface of the base 1 is fixedly connected to the second fixing plate 12. There are two connecting seats 13, which are distributed on the left and right. The outer surface of the second limiting block 11 is slidably connected to the hexagonal sleeve 21. The right surface of the second fixing plate 12 is in contact with the second limiting block 11. The left surface of the first fixing plate 8 is in contact with the first limiting block 10.

[0028] The right end of the second limiting block 11 is fixedly connected to the limiting plate 19. A spring 20 is provided on the outer surface of the second limiting block 11.

Then rotate the hexagonal sleeve 21, which, under the limiting action of the limiting plate 19, will drive the bidirectional threaded rod 9 to rotate as a whole, thereby causing the two connecting seats 13 to move away from each other. At this time, under the action of the fixing post 14, connecting strip 15, connecting post 16 and fixing seat 17, the two insert blocks 18 will move closer to each other, and then the guide rail 3 to be installed will be installed. Align the snap block 7 below the guide rail 3 with the through slot 24 and insert it. When the insertion hole 25 on the snap block 7 corresponds to the insertion block 18, simply rotate the hexagonal sleeve 21 in the opposite direction as described above to drive the two insertion blocks 18 away from each other. Finally, insert them into the insertion hole 25 to install the guide rail 3. Then, release the hexagonal sleeve 21. Under the rebound force of the spring 20, the insertion plate 22 will automatically insert into the slot 23, thereby limiting the rotation of the bidirectional threaded rod 9 and preventing it from loosening and falling off.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
