DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] A roller platform of a lift, such as Figure 1 As shown, it includes a base 1 and a lifting platform 2. A lifting drive assembly 11 is provided on the base 1, so that the lifting platform 2 can rise and fall smoothly. A plurality of rollers 21 are provided on the lifting platform 2, and the rollers are used to convey materials. Retractable limiting bodies 3 are provided on both sides of the lifting platform 2, so that the distance of the baffle 7 can be adjusted, so that materials of different sizes can be limited. The limiting body 3 is provided with a baffle 7, which can protect the material and prevent the material from falling during transportation on the roller 21, thereby further improving the limiting effect on the material.

[0030] like Figures 1 to 5 As shown, the limiting body 3 includes a first extension block 33, a second extension block 32 and a third extension block 31, and the three extension blocks are sequentially sleeved and connected, thereby achieving the effect of extension block telescoping. The first extension block 33 and the second extension block 32 are both provided with grooves 4, and the grooves 4 achieve the limiting effect on the second extension block 32 and the third extension block 31, further improving the limiting effect on the second extension block 32 and the third extension block 31, and rotation grooves 41 are provided on both sides of the grooves 4, and a rotation column 42 is provided on the grooves 4, and the rotation column 42 is rotatably connected in the rotation grooves 41, and a movable plate 5 is provided on the rotation column 42, and the movable plate 5 is rotatably connected to the rotation column 42, thereby achieving the effect of flipping the movable plate 5, and the second extension block 32 and the third extension block 31 are provided with a clamping groove 6, and a tension spring 51 is provided on the movable plate 5, and a clamping block 52 is provided on the tension spring 51. When the second extension block 32 is in the limit tension state, the first extension block 33 is The block 52 connected via the movable plate 5 just contacts the end of the second extension block 32 in the first extension block 33 to limit the retraction of the second extension block 32. When people press the movable plate 5 on the first extension block 33 to move the block 52 to the rotating groove 41 on the first extension block 33, the contact limits the second extension block 32. The tension spring 51 stretches the block 52, which further limits the slot 6. By flipping the movable plate 5, the block 52 can be embedded in the slot 6, thereby achieving the limiting effect on the second extension block 32 and the third extension block 31. The movable plate 5 is provided with anti-slip grooves 8, so that when the movable plate 5 is flipped, the friction can be increased, thereby achieving the effect of facilitating the flipping of the movable plate 5.

[0031] like Figure 5As shown, the baffle 7 is provided with a plurality of elastic protrusions 71, so that during the transportation of the material by the roller 21, the elastic protrusions 71 can limit and protect the material, thereby further improving the safety of the material during transportation. An inverted T-shaped block 72 is provided at the bottom end of the baffle 7, and an inverted T-shaped groove 331 is provided on the third extension block 31. The inverted T-shaped block 72 is embedded in the inverted T-shaped groove 331. The inverted T-shaped block 72 and the inverted T-shaped groove 331 cooperate to form a detachable connection, thereby strengthening the connection strength between the baffle 7 and the third extension block 31, and ensuring that the baffle 7 will not shake when being engaged with the third extension block 31.

[0032] Working principle: the lifting platform 2 is raised by the lifting drive assembly 11, and the material is transported to the other side through the roller 21 on the lifting platform 2. During the transportation, the first extension block 33, the second extension block 32 and the third extension block 31 are sequentially sleeved and connected, and the inverted T-shaped block 72 at the bottom end of the baffle 7 is embedded in the inverted T-shaped groove 331 on the third extension block 31, so that the baffle 7 is clamped with the third extension block 31. When the material is transmitted on the roller 21 on the lifting platform 2, it will hit the elastic protrusion 71 on the baffle 7 to reduce damage to the material. The movable plate 5 on the second extension block 32 is flipped to stretch the spring, thereby driving the block 52, so that the block 52 is embedded in the slot 6 of the third extension block 31, further fixing the second extension block 32 to the third extension block 31. When it is necessary to release the fixation of the second extension block 32 and the third extension block 31, the movable plate 5 is toggled to release the block 52 from the slot 6.
