The shaped shell 41 of the upper stopper 4 is a right-angled turning part, and a part connected with the rail cross bar 201 is also a triangular shell, and a vertical bar stopping groove 44 is arranged at the turning part and used for inserting the top end of the vertical bar 202.
Another part of the mould shell 41 abuts against the slide 2 to form a complete triangle. When the sliding sleeve 21 is butted, the sliding sleeve 21 is inserted into the guiding groove 42, and the first butting surface 411 contacts with the second butting surface 221.
Further, as shown in fig. 13-15 and 19, the lifting assembly 10 further comprises a lower stopper 5, the lower stopper 5 comprising a shoe shell 51 and a lower rail groove 52;
the shell 51 is fixedly connected to a vertical rod 202 of the crib, and the lower end of the lifting guide rail 1 is inserted into the lower rail blocking groove 52.
Specifically, an arc-shaped surface is formed on the tile shell 51, and the arc-shaped surface is attached to the vertical rod 202 and is fixedly connected with the vertical rod through a screw. The lower rail groove 52 is for inserting the lower end of the lifting rail 1.
As shown in fig. 13, the lower stopper 5 is fixed to the vertical rod 202. When the sliding part 2 slides downwards, the sliding sleeve 21 of the sliding part 2 collides with the lower stop part 5, and the lower stop part 5 plays a role in limiting the sliding part 2 to continue sliding downwards.
As shown in fig. 20, a lock groove 11 is formed in the upper portion of the lifting slide rail 1, the position of the lock groove 11 corresponds to the highest position of the upward sliding of the slider 2, and at this time, the insertion portion 311 of the lock plate 31 can be inserted into the lock groove 11, so as to lock the lock plate 31 and the lifting slide rail 1, and prevent the slider 2 from sliding downward.
In this embodiment, the lower portion of the lifting slide rail 1 has no locking groove, and the lower stopping member 5 and the lowest position of the sliding member 2 have a stopping function, so that the locking groove of the lower portion may not be provided. At this time, the insertion portion 311 of the locking plate 31 abuts against the surface of the lifting slide rail 1, and a certain friction effect is generated, so that the slider 2 is not easily driven to slide upwards.
Optionally, a lock groove may be added to the lower portion of the lifting slide rail 1.
Through implementing this embodiment, can realize the oscilaltion with lifter 201a to satisfy the different demands of crib.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
