Embodiment

[0024] Example: as attached figure 1 , 2 , 3, 4, 5 and attached Figure 6 As shown, a screw rod for lifting a high-safety seat includes an outer sleeve unit 1 with an opening facing upwards, and a screw main body unit 2 arranged in the outer sleeve unit 1 and fixed in the circumferential direction is plugged in. The inner sleeve unit 3 screwed to the screw body unit 2 on the outer sleeve unit 1 with the opening facing down, and inserted into the outer sleeve unit 1 and the inner sleeve unit 3 The insertion column unit 4 on the side wall is used to fix the height of the screw rod by circumferentially fixing the inner sleeve unit 3 .

[0025] In this embodiment, the outer sleeve unit 1 is the mounting base of the screw main body unit 2, the inner sleeve unit 3 is connected to the seat body, and the lifting adjustment is realized by rotating up and down, and finally the The plug-in column unit 4 is plugged and fixed on the outer sleeve unit 1 to fix the inner sleeve unit 3, so...

Abstract

The invention belongs to the technical field of a screw rod structure, in particular to a screw rod for high-safety chair ascending and descending. The effect of preventing the screw rod for ascendingand descending from rotating and falling down is achieved in a mode of installing a screw rod main body unit, an inner sleeve tube unit and an insertion connection post unit on the outer sleeve tubeunit. The screw rod has the advantages that a screw rod clamping falling-prevention structure is reasonable and effective; the clamping state building and relieving operation is convenient and fast; the screw connection integral ascending and descending use effect is good; the accidental rotating falling cannot easily occur.

Description

technical field [0001] The invention belongs to the technical field of screw structures, and in particular relates to a screw for lifting and lowering a high-safety seat. Background technique [0002] The seat lifting structure generally includes two methods: cylinder and screw. The former has the risk of explosion, while the latter is relatively easy to accidentally rotate and fall. Therefore, a screw with self-locking function is particularly urgently needed. The chair will not fall down after being adjusted to a certain height, ensuring the safety of screw height adjustment. [0003] The patent announcement number is CN205226257U, and the Chinese utility model patent with the announcement date of 2016.05.11 discloses a structure that prevents the screw from rotating in a natural state. The platform ensures that the screw has no degree of freedom in the direction of rotation. [0004] But the screw rod in this utility model patent has the problem that the function effect...
