[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A labor-saving device for automatic lifting of a material box comprises a frame and a material box, pulleys are respectively installed on the front and rear sides of the upper part of the frame, guide rods are respectively installed on the left and right sides of the frame, a counterweight assembly is slidably connected between the guide rods on both sides, a material box is installed inside the frame, a steel wire rope is connected to the top of the material box, and the steel wire rope passes around the pulley and is connected to the counterweight assembly.

[0006] In the above scheme, the counterweight assembly includes a load-bearing base, a counterweight block and a guide wheel. The counterweight block is installed on the load-bearing base, the guide wheels are fixed at both ends of the load-bearing base, and the wheel body of the guide wheel is slidably connected to the front of the guide rod; the load-bearing base is provided with at least one, and the top of the top load-bearing base is equipped with a lifting ring connected to the wire rope.

[0007] In one embodiment, the counterweight assembly further includes a connecting rod that separates the plurality of counterweight blocks. Further, the counterweight assembly further includes a stacking rod that separates the plurality of counterweight blocks, and the ends of the stacking rods are provided with support ends that are slidably connected to the sides of the guide rods.

[0008] The above solution further includes a conveyor belt and a frame, wherein at least one conveyor belt is provided and installed in the frame; the frame is installed on one side of the frame. As a preferred solution, the conveyor belt is provided with a track, and rollers are evenly installed on the inner side of the track.

[0009] Compared with the prior art, the present invention has the following advantages: one end of the wire rope is connected to the top of the material box to pull the material box, while the other end is fixed to the top of the counterweight assembly. By utilizing the sliding properties of the pulley, a pulley mechanism is formed, thereby saving labor. Furthermore, due to the working mode of the counterweight assembly, when there is no material in the material box or the weight is less than the counterweight assembly, the material box rises to the top. When the material in the material box exceeds the weight of the counterweight assembly, the material box descends to the bottom of the frame due to gravity. This pulley mechanism enables loading and unloading of materials, saving manpower and production costs, and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0019] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0020] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1, as Figure 1 and Figure 2 As shown, a labor-saving automatic lifting device for a material bin comprises a frame 1 and a material bin 2. Pulleys 11 are mounted on the front and rear sides of the upper portion of the frame 1. Pulleys 11 are secured to the frame 1 via brackets and freely rotate with the brackets via a rotating shaft. Guide rods 12 are fixedly mounted on the left and right sides of the frame 1, serving as guides. A counterweight assembly 3 is slidably connected between the guide rods 12 on either side. These guides guide the counterweight assembly 3, allowing it to move linearly in the vertical direction.

[0022] A material box 2 is installed inside the frame 1. A steel wire rope (not shown) is connected to the top of the material box 2. The steel wire rope passes through a pulley 11 and is connected to the counterweight assembly 3. During implementation, one end of the steel wire rope is connected to the top of the material box 2 to pull the material box 2, and the other end is fixed to the top of the counterweight assembly 3. By utilizing the sliding performance of the pulley 11, a pulley mechanism is formed, thereby saving effort. In addition, due to the working mode of the counterweight assembly 3, when there is no material placed in the material box 2, or the weight is less than the counterweight assembly 3, the material box 2 rises to the top. When the material placed in the material box 2 is greater than the weight of the counterweight assembly 3, the material box 2 drops to the bottom of the frame 1 due to gravity. The pulley mechanism is used to achieve loading and unloading of materials, saving manpower and production costs, and improving work efficiency.

[0023] For specific implementation, please refer to Figure 2 and Figure 3 The counterweight assembly 3 includes a bearing base, a counterweight 33, and guide wheels 36. The counterweight 33 is mounted on the bearing base, and the guide wheels 36 are fixed at both ends of the bearing base. The guide wheels 36 are slidably connected to the front of the guide rod 12, allowing them to guide the load in the vertical direction when the pulley mechanism is implemented. The bearing base is equipped with at least one lifting ring 31 connected to a steel wire rope at the top of the bearing base, thereby lifting the entire counterweight assembly 3.

[0024] In one embodiment, the counterweight assembly 3 further includes a connecting rod 32, which separates the multiple counterweight blocks 33 and provides a slot for inserting the counterweight blocks 33. Furthermore, the counterweight assembly 3 further includes a stacking rod 34, which also separates the multiple counterweight blocks 33 and provides a slot for inserting the counterweight blocks 33. The difference is that the end of the stacking rod 34 is provided with a supporting end 35 that is slidably connected to the side of the guide rod 12. The supporting end 35 is a hook-shaped structure, while the guide rod 12 is a T-shaped structure as a whole. The wheel body of the guide wheel 36 is a U-shaped structure, which is stuck on the front of the guide rod 12 with the T-shaped structure and is slidably connected thereto. The supporting end 35 of the hook-shaped structure is stuck on the side of the guide rod 12 with the T-shaped structure and is slidably connected thereto.

[0025] Example 2, please refer to Figure 4 、 Figure 5 、 Figure 6 A labor-saving device for automatically lifting a material box includes a frame 1 and a material box 2, a conveyor belt 4 and a frame 43. At least one conveyor belt 4 is provided and installed in the frame 43 for conveying the material box 2.

[0026] Among them, the frame 43 is installed on one side of the frame body 1. As a structure with an automatic lifting and labor-saving device on only one side, it can also be installed as follows Figure 5 As shown, the structure of the automatic lifting and labor-saving device is set on both sides of the frame 43 to automatically lift the materials in the workshop.

[0027] As a preferred solution, a track 41 is provided on the conveyor belt 4, and rollers 42 are evenly installed on the inner side of the track 41. When the conveyor belt 4 is tilted, the material box 2 will be automatically transported to a certain position due to the action of the rollers 42, which is convenient for production personnel to load and unload materials.

[0028] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
