[0026] Please see Figs. 1-3 This utility model provides a technical solution: an electric hydraulic lifting trolley, comprising;
[0027] The folding lifting assembly includes a lower base 100, a lower crossarm bracket A101, a lower crossarm bracket B102, a lower connecting frame 103, an upper base 200, an upper crossarm bracket A201, an upper crossarm bracket B202, an upper connecting frame 203, and an electric hydraulic rod 300.
[0028] There are two lower crossarm brackets A101 and B102. The bottom of both lower crossarm brackets A101 and B102 is hinged to the lower base 100. There are two upper crossarm brackets A201 and B202. The bottom of both upper crossarm brackets A201 and B202 is hinged to the upper base 200. The other end of lower crossarm bracket A101 is hinged to upper crossarm bracket B202, and the other end of lower crossarm bracket B102 is hinged to upper crossarm bracket A201.
[0029] There are two lower connecting frames 103. One end of the lower connecting frame 103 is hinged to the lower crossarm bracket B102 and the upper crossarm bracket A201, and the other end of the lower connecting frame 103 is hinged to the lower crossarm bracket A101 near the middle. There are two upper connecting frames 203. One end of the upper connecting frame 203 is hinged to the upper crossarm bracket B202 and the lower crossarm bracket A101, and the other end of the upper connecting frame 203 is hinged to the upper crossarm bracket A201 near the middle.
[0030] The electro-hydraulic rod 300 is located between the lower base 100 and the upper base 200. The two ends of the electro-hydraulic rod 300 are respectively provided with drive rod A301 and drive rod B302. The two ends of drive rod A301 are connected to two lower connecting frames 103, and the two ends of drive rod B302 are respectively connected to two upper connecting frames 203.
[0031] Furthermore, the upper crossarm bracket A201 is parallel to the lower crossarm bracket A101. When the upper crossarm bracket A201 and the lower crossarm bracket A101 are folded, they are placed in a staggered parallel position to save space to the maximum extent.
[0032] Furthermore, the upper crossarm bracket B202 is parallel to the lower crossarm bracket B102, and the upper crossarm bracket A201 and the lower crossarm bracket A101 are placed in a staggered parallel position when folded to save space to the maximum extent.
[0033] Furthermore, the bottom of the lower base 100 has an adhesively fixed anti-slip pad to prevent slippage when the lower base 100 contacts the ground for support, thereby improving the stability of the structure.
[0034] Furthermore, the top of the upper base 200 has a shelf 400, and the bottom of the shelf 400 has two symmetrical slide rails 401. The slide rails 401 are fastened to the top of the upper base 200 and slidably connected thereto. The shelf 400 can slide on the top of the upper base 200. When the upper base 200 is raised, the shelf 400 can slide on the top of the upper base 200 and extend into the carriage for loading and unloading goods, thereby improving the efficiency of loading and unloading goods.
[0035] Furthermore, the bottom of the shelf 400 has multiple casters 402. When the folding lifting assembly is folded, the bottom of the casters 402 is lower than the lower base 100, and the casters 402 are in contact with the ground and used as a mobile trolley.
[0036] Furthermore, the top of the shelf 400 has a handle 404, and the bottom of the handle 404 has a latch. By opening and closing the latch, the handle 404 can be raised and folded to save space when not in use.
[0037] Furthermore, one end of the shelf 400 has an operation box 403, through which the extension and retraction of the electric hydraulic rod 300 can be controlled.
[0038] Working principle: In use: Goods can be stacked on the shelf 400. Activating the electric hydraulic rod 300 retracts the push rod, reducing the distance between drive rods A301 and B302. This causes the lower connecting frame 103 and the upper connecting frame 203 to be simultaneously stressed. The lower connecting frame 103 drives the lower crossarm brackets A101, B102, and A201, while the upper connecting frame 203 drives the lower crossarm brackets B102, A201, and B202. This multi-rod support pushes the shelf 400 upwards, raising it. The shelf 400 can slide on top of the upper base 200. When the upper base 200 is raised, the shelf 400 can slide on top of the upper base 200 and extend into the cargo compartment for loading and unloading goods, thus improving loading and unloading efficiency. Conversely, the push rod on the electric hydraulic rod 300 extends, causing the multi-rod to retract, lowering the shelf 400 back to its original position.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
