Description

Technical Field

[0001] The utility model relates to the technical field of telescopic conveyor lines, in particular to a telescopic conveyor line lifting structure. Background Art

[0002] Telescopic conveyor lines are widely used in logistics systems. When telescopic conveyor lines are used, the upper shaft is fixed and the lower shaft slides up and down to achieve the telescopic adjustment of the conveyor line. Some telescopic conveyor lines on the market now have defects:

[0003] 1. The telescopic conveyor line needs to fix the upper shaft during use, and the lower shaft that slides up and down during extension and retraction can realize the telescopic effect of the telescopic conveyor line. The existing technology generally uses a sleeve method to achieve this. The upper shaft fixes the upper sleeve, and the lower shaft is fixed to the lower movable sleeve to realize the lower shaft sliding up and down when the product is extended and retracted. This structural defect requires the use of upper and lower sleeve accessories, which is easy to scratch the surface of the equipment when sliding up and down. Long-term use increases the wear on the surface of the equipment. When stretching or contracting, it is easy to pinch your hands and cause injuries if you hold the sleeve, and it is impossible to adjust the height of the telescopic conveyor line up and down;

[0004] 2. Another existing structure is that the upper shaft is fixed and the lower shaft is movable. Other auxiliary accessories need to be added by welding or fixing them on the telescopic conveyor line legs with screws to realize the lower shaft sliding up and down. The defects are high labor costs and accessory costs. If the fixing with the main legs is not firm, accidents are prone to occur, and the telescopic conveyor line cannot be adjusted in height up and down. Utility Model Content

[0007] Among them, an upper fixed axis connected to the telescopic frame on the telescopic conveyor line is arranged on the upper side between the two outer supporting feet, and a lower fixed axis that can slide up and down following the telescopic frame when it is extended and retracted is slidably arranged on the lower side between the two outer supporting feet, and sliding grooves for the lower fixed axis to slide up and down are respectively arranged on the opposite sides of the two outer supporting feet.

[0008] Furthermore, the two outer supporting feet are provided with installation links for connecting the split supporting leg transverse tie rods, and the installation links are provided with several connecting threaded holes in the axial direction, and U-shaped screw holes corresponding to the connecting threaded holes are provided at both ends of the split supporting leg transverse tie rods.

[0009] Furthermore, one end of the sliding groove has a mounting hole for mounting the lower fixed axis into the sliding groove.

[0010] Furthermore, through-connecting holes are arranged on the two outer supporting legs of the upper fixed axis, the upper fixed axis is installed on the through-connecting holes, and the through-connecting holes are provided with locking hole plastic covers.

[0011] Furthermore, through-connecting holes are arranged on the two outer supporting legs of the upper fixed axis, the upper fixed axis is installed on the through-connecting holes, and the through-connecting holes are provided with locking hole plastic covers.

[0012] Furthermore, a universal caster with a brake is connected to the bottom of the inner supporting leg outside the exposed outer supporting leg.

[0013] Furthermore, both ends of the upper fixed axis and the lower fixed axis are provided with detachable fixing plugs.

[0014] The beneficial effects achieved by the utility model are as follows: by arranging sliding grooves on the two outer supporting legs for the lower fixed axis to slide up and down, when the telescopic frame is extended or retracted, the lower fixed axis can slide up and down following the extension or retraction of the telescopic frame, and can slide up and down without the assistance of any accessories, thereby effectively saving costs; since there are no up and down sliding accessories on the outer supporting legs, hand pinching accidents will not occur after the improvement; and the inner supporting legs are slidably sleeved inside the outer supporting legs, so that the height can be adjusted, and the inner supporting legs are locked to the outer supporting legs by locking parts, thereby meeting the customer's requirements for the height of the telescopic conveyor line.

By providing the fixing plugs 104, the upper fixed axis 102 and the lower fixed axis 103 are prevented from falling off the outer supporting legs 201.

[0025] To sum up, the utility model provides sliding grooves 2013 on the two outer supporting legs 201 for the lower fixed axis 103 to slide up and down, so that when the telescopic frame 10 is extended or retracted, the lower fixed axis 103 can slide up and down along with the extension or retraction of the telescopic frame 10, and can slide up and down without the assistance of any accessories, thereby effectively saving costs. Since there are no up and down sliding accessories on the outer supporting legs, hand pinching accidents will not occur after the improvement; and the inner supporting leg 203 is slidably sleeved on the outer supporting leg 201, so that the height can be adjusted, and the inner supporting leg 203 is locked to the outer supporting leg 201 by the locking member 205, thereby meeting the customer's requirements for the height of the telescopic conveyor line.
