Embodiment 1
[0047] Such as Figure 1 ~ Figure 4 As shown, a space-expanding linear motion mechanism of this embodiment includes an unfolding platform 100 and an X-axis movement assembly 300. The X-axis movement assembly 300 includes a first slider 311 and a first driving device. The deployment platform 100 is horizontally installed with a first guide rail 301 and a first rack 302, and the drive end of the first drive device is connected with a first drive gear 305 that is fit and meshed with the first rack 302, and the first drive The device is installed on the first slider 311; the first slider 311 is provided with a first roller 306 and a second roller 307, and the first roller 306 and the second roller 307 are respectively slidably connected to the first guide rail On the upper and lower sides of 301, the first slider 311 is also provided with a lever loading device, which is connected with the first roller 306 or the second roller 307 and holds the first roller 306 or the second rolle...
Embodiment 2
[0061] Such as Figure 1 to Figure 9 As shown, a load extension and retraction device of this embodiment includes the space extension and extension linear motion mechanism, and also includes an extension and extension drive mechanism and a locking mechanism. The power part of the extension and extension drive mechanism is installed on two adjacent On one of the unfolding platforms 100 of the two unfolding platforms 100, the transmission gear 104 of the unfolding drive mechanism is rotatably connected to the hinges 122 of two adjacent unfolding platforms 100, and is connected with the other unfolding platform 100; the lock The tightening mechanism includes a latch 125 and a locking assembly 126, and the latch 125 and the locking assembly 126 are respectively installed on two adjacent deployment platforms 100; The gear 104 is connected by transmission and drives the transmission gear 104 to rotate around the hinge 122, and then drives another unfolding platform 100 to rotate aro...
