If the weight is too loud, the speed of the falling speed will be too fast, and the positional energy can be converted into spring energy by the tension springs 46 when the top frame 3 3 is lowered, and the top frame 3 3 When the lift is raised, the spring can be restored, so that the operating force of the top frame 3 3 is raised or lowered, and the operating force can be evenly close. As shown in Fig. 6, when the loaded object 1 is subjected to the lifting mechanism 4, the top When the support is removed from the ground, the inner rail group 2 1 and the trolley 3 1 can be slid and moved to a retracted position, and thereby the loaded object i can be smoothly transported to a container 1 〇 2, and when the inner rail group 2 1 and the trolley 3 丄 are in the retracted position, the inner positioning holes 28 of the inner group 2 1 are respectively positioned outside the outer rail group 1 i 9 corresponding to each other, and each of the positioning pins 18 respectively passes through the corresponding inner positioning hole 28 and the outer positioning hole 9' to position the inner rail group 2 1, and the inner rail group 2 1 is fixed The holes 26 6 are aligned with the respective positioning holes 37 of the pulleys, and then the fixing pins 38 are respectively passed through the mutually aligned positioning holes 26 and the pulley positioning holes 3 201002573 7 to position the pulley 3 1 . And by the above-mentioned positioning means, the stability of the load when the container is carried in the process can be effectively ensured. The invention consisting of the above structure has the following advantages: 1. The invention is slippery The rail design has the characteristics of easy and rapid operation. 2 · The design of the double-layer slide rail can effectively prevent the slide rail from being pulled too much, and excessive bending distance is generated for the structure, and by sliding half distance If the force distance is half, the structural burden can be effectively reduced. 3. The lifting device of the present invention is capable of raising or lowering a load on a loaded object, so that the loaded object is lowered during transportation and supported by the wheel body to reduce the load. Under the influence of transportation vibration, when the object to be stored is to be stored for a long time, the load can be raised by the lifting device to prevent deformation of the wheel body due to long-term pressure. 4. The lifting mechanism of the present invention utilizes a horizontally disposed tension spring to convert the potential energy and the spring energy, so that the position can be converted into a spring energy when the lowering is performed, and the spring can be restored when raised, and thereby the gravity is not lowered when lowered. There is an acceleration phenomenon, which can be controlled to stop at any time. When it is raised, it will not be difficult to operate due to gravity, so that the operating force of both the ascending and descending is uniform. 5. The present invention can quickly lock the position of the inner rail set and the trolley by the wearing of the fixing pins, and the fixed pin systems are all designed as shear pins, and are quick-release pins, and have disassembly and assembly. Convenient features. 12 201002573 and by the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in compliance with the provisions of the Patent Law. Therefore, the applicant of the present invention filed a patent application. 13 201002573 [Simplified illustration of the drawings] Fig. 1 is a perspective exploded view of the present invention.
