The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a front view of the entire utility model. Figure 3 This is a side view of the entire utility model.

[0019] This utility model provides a hand-cranked lifting workbench, including a hand-cranked lifting assembly. The assembly includes a base frame 101, a column 102, a telescopic rod 103, a connecting block 104, a carrier 105, a product 106, a crossbar 107, a worm gear lifter 108, a screw 113, a coupling 109, a transmission rod 110, a handwheel 111, and an auxiliary handle 112. This solution solves the problem of battery pack swaying freely after hoisting, causing a lack of safety for workers below. Understandably, when the workbench is in its initial state, the base frame 101 is firmly rooted in a flat surface, providing a solid support foundation for the entire workbench. The column 102 stands vertically and is tightly connected to the base frame 101, as if... A sturdy fortress-like pillar supports all the components above. The telescopic rod 103, the connecting block 104, and the carrier 105 are installed sequentially. At this time, the carrier 105 is in a lower position, ready to carry the product 106. The operator carefully places the battery pack inside the carrier 105 and secures it firmly using pre-set clamps or slots. These positioning and fixing devices are carefully designed to adapt to the size and shape of the battery pack, ensuring that the battery pack remains horizontal on the carrier 105 and parallel to the base frame 101, avoiding problems in subsequent operations due to improper placement. After preparation, the operator walks to the workbench and holds the auxiliary handle 112 with both hands. When the palm of the hand rests against the surface of the auxiliary handle 112, feeling the comfortable grip provided by its material, the arm exerts force to rotate the handwheel 111 clockwise with a uniform and stable force. The handwheel 111 is in close contact with the operator's hand. As it rotates, the texture on its surface increases friction, making the rotation process more controllable. The rotation of the handwheel 111 is like starting the "engine" of the entire workbench. It is tightly connected to the worm gear lift 108 through a detachable connection. The moment the handwheel 111 rotates, the worm gear lift 108 immediately responds and begins to work. The worm and worm wheel inside the worm gear lift 108 mesh with each other, converting the rotational motion of the handwheel 111 into power transmission in a specific direction. In this process... The meshing accuracy between the worm and worm wheel is crucial. Precise meshing ensures efficient and stable power transmission, reduces energy loss and component wear. After the worm jack 108 operates, it transmits power to the transmission rod 110 via the coupling 109. The coupling 109, as a key component connecting the worm jack 108 and the transmission rod 110, plays a role in stabilizing power transmission and compensating for relative displacement between the two shafts. It is tightly fixed to one side of the worm jack 108 and installed above the crossbeam 107. When the worm jack 108 transmits power, the coupling 109 quickly and accurately transmits the power to the transmission rod 110, causing the transmission rod 110 to begin rotating.During rotation, the transmission rod 110, thanks to its structural strength and design features, stably transmits power to the next component. Simultaneously, the worm gear jack 108 drives the screw 113 to rotate. One end of the screw 113 is detachably connected to the upper center of the worm gear jack 108, while the other end is tightly connected to the lower side of the carrier 105. When the screw 113 rotates, its helical groove interacts with the corresponding structure on the carrier 105, generating upward or downward thrust. Because the screw 113 and the extension... The telescopic rods 103 are arranged in parallel and provide guidance for the lifting and lowering of the carrier 105. Therefore, during the rotation of the screw 113 to generate thrust, the carrier 105 can move smoothly up and down along the direction of the telescopic rods 103. During the ascent of the carrier 105, the operator constantly monitors the position and status of the battery pack. As the carrier 105 slowly rises, the battery pack gradually moves away from the ground and towards the appropriate working height. Due to the reasonable design of the workbench and the tight cooperation between the components, the battery pack remains stable throughout the ascent. Without any wobbling, when the battery pack rises to the appropriate height, the operator stops turning the handwheel 111. At this time, the worm gear jack 108 stops working, and the screw 113 also stops rotating. The carrier 105, relying on its own structure and the connection relationship between its various components, remains steadily in its current position. The worker stands under the stable battery pack and begins the work of attaching the cushioning cotton. Compared with the previous use of a gantry crane to lift the battery pack, the battery pack no longer wobbles, allowing the worker to operate more calmly and precisely. They can carefully measure the cushioning cotton. The dimensions are accurately measured and pasted onto the bottom of the battery pack, ensuring the pasting effect meets production requirements. Throughout the operation, the workbench remains stable, providing a safe and reliable working environment for workers, greatly improving work efficiency and product quality. After the operation is completed, the operator holds the auxiliary handle 112 again and turns the handwheel 111 counterclockwise, repeating the above power transmission and component movement process, causing the carrier 105 to slowly descend and safely return the battery pack to its initial position. Subsequently, the operator carefully removes the battery pack from the carrier 105, completing one full workflow cycle.

[0020] In this specific embodiment, the column 102 is detachably connected to the base frame 101 and is located on the upper side of the base frame 101, with the column 102 and the base frame 101 arranged vertically. The telescopic rod 103 is detachably connected to the column 102 and is located above the column 102. The connecting block 104 is detachably connected to the telescopic rod 103 and is located above the telescopic rod 103. The carrier 105 is detachably connected to the connecting block 104 and is located on one side of the connecting block 104, with the carrier 105 and the connecting block 104 arranged vertically. The carrier 105 is also arranged parallel to the base frame 101. The base frame 101 is placed stably on the work site, ensuring it is in a horizontal state to guarantee the stability of the entire workbench. Then, the column 102 is vertically installed on the upper side of the base frame 101 using bolts or other detachable connection methods. The bolts are tightened to ensure that the column 102 and the base frame 101 are firmly connected.

[0021] The product 106 is detached from the carrier 105 and located inside the carrier 105. The product 106 is parallel to the base frame 101. The product 106, which requires bottom cushioning, is placed inside the carrier 105. The product 106 is then detached from the carrier 105 to ensure that the product 106 is stably placed on the carrier 105 and is parallel to the base frame 101.

[0022] Secondly, the crossbeam 107 is detachably connected to the column 102 and is located on the upper side of the column 102, and the crossbeam 107 is perpendicular to the column 102. The worm gear lifter 108 is detachably connected to the crossbeam 107 and is located at the center of the upper side of the crossbeam 107. One end of the screw 113 is detachably connected to the worm gear lifter 108 and is located at the center of the upper side of the worm gear lifter 108. The other end of the screw 113 is detachably connected to the carrier 105 and is located below the side of the carrier 105, and the screw 113 is parallel to the telescopic rod 103.

[0023] Meanwhile, the coupling 109 is fixedly connected to the worm gear jack 108 and located on one side of the worm gear jack 108. The coupling 109 is positioned above the crossbeam 107. The transmission rod 110 is rotatably connected to the coupling 109 and is located above the coupling 109 on the side away from the worm gear jack 108. The crossbeam 107 is vertically installed on one side above the column 102, ensuring that the crossbeam 107 is securely installed and perpendicular to the column 102. The worm gear jack 108 is then installed on the crossbeam. At the center of the upper side of the 107, use bolts or other connectors to fix one end of the screw 113 to the upper center of the worm gear jack 108, and connect the other end to the lower side of the carrier 105, so that the screw 113 and the telescopic rod 103 are arranged parallel to each other. Fix the coupling 109 to one side of the worm gear jack 108 and ensure that it is installed above the cross frame 107. Then, rotatably connect the transmission rod 110 to the coupling 109 to ensure that the transmission rod 110 can rotate flexibly.

[0024] In addition, the handwheel 111 is detachably connected to the worm gear jack 108 and is located on the side of the worm gear jack 108 away from the coupling 109. The handwheel 111 is perpendicular to the worm gear jack 108. The auxiliary handle 112 is fixedly connected to the handwheel 111 and is located on the side of the handwheel 111 away from the worm gear jack 108. When it is necessary to attach cushioning cotton to the bottom of the product 106, the operator holds the auxiliary handle 112 and rotates the handwheel 111. The rotation of the handwheel 111 drives the worm gear jack 108 to work. The worm gear jack 108 transmits power to the transmission rod 110 through the coupling 109, and at the same time drives the screw 113 to rotate.

[0025] When using this utility model, in the initial state of the workbench, the base frame 101 is firmly rooted in the flat ground, providing a solid support foundation for the entire workbench. The upright column 102 stands vertically and is tightly connected to the base frame 101, acting like a sturdy fortress pillar, supporting all the components above. The telescopic rod 103, the connecting block 104, and the carrier 105 are installed in sequence. At this time, the carrier 105 is in a lower position, waiting to carry the product 106. The operator carefully places the battery pack inside the carrier 105 and secures it firmly using pre-set clamps or slots and other positioning and fixing devices. These positioning and fixing devices are carefully designed to accommodate the size of the battery pack. The dimensions and shape are adapted to ensure the battery pack remains horizontal on the carrier 105 and parallel to the base frame 101, avoiding problems in subsequent operations due to improper placement. After preparation, the operator walks to the workbench, grasps the auxiliary handle 112 with both hands, and feels the comfortable grip of the material against the surface of the auxiliary handle 112. The operator then applies force with their arm, rotating the handwheel 111 clockwise with even and stable force. The handwheel 111 is in close contact with the operator's hand; as it rotates, the texture on its surface increases friction, making the rotation process more controllable. The rotation of the handwheel 111 is like starting the "engine" of the entire workbench. It is tightly connected to the worm gear lift 108 through a detachable connection. Connected, the worm gear jack 108 responds immediately upon the rotation of the handwheel 111 and begins operation. The worm and worm wheel inside the worm gear jack 108 mesh with each other, converting the rotational motion of the handwheel 111 into power transmission in a specific direction. In this process, the meshing accuracy between the worm and worm wheel is crucial; precise meshing ensures efficient and stable power transmission, reducing energy loss and component wear. After the worm gear jack 108 operates, it transmits power to the transmission rod 110 via the coupling 109. The coupling 109, as a key component connecting the worm gear jack 108 and the transmission rod 110, plays a crucial role in stably transmitting power and compensating for relative displacement between the two shafts. The coupling 109 is tightly fixed to one side of the worm gear jack 108 and installed above the crossbeam 107. When the worm gear jack 108 transmits power, the coupling 109 quickly and accurately transmits the power to the transmission rod 110, causing the transmission rod 110 to start rotating. During rotation, the transmission rod 110, with its own structural strength and design features, stably transmits power to the next component. At the same time, the worm gear jack 108 also drives the screw 113 to rotate. One end of the screw 113 is connected to the upper center of the worm gear jack 108 by a detachable connection, and the other end is tightly connected to the lower side of the carrier 105. When the screw 113 rotates...Its spiral pattern interacts with the corresponding structure on the carrier 105, generating upward or downward thrust. Since the screw 113 and the telescopic rod 103 are arranged parallel to each other, and the telescopic rod 103 provides guidance for the lifting and lowering of the carrier 105, the carrier 105 can move smoothly up and down along the direction of the telescopic rod 103 during the rotation of the screw 113 to generate thrust. During the ascent of the carrier 105, the operator constantly monitors the position and status of the battery pack. As the carrier 105 slowly rises, the battery pack gradually moves away from the ground and towards the appropriate working height. Due to the reasonable design of the workbench and the tight fit between the components, the battery pack remains stable during the ascent without any shaking. When the battery pack rises to the appropriate height, the operator stops turning the handwheel 111. At this time, the worm gear lift 108 stops working, and the screw 113 also stops rotating. The carrier 105, relying on its own structure and the connection relationship between its components, remains stably in its current position. Workers stand beneath the stable battery pack and begin the cushioning cotton application. Compared to the previous method of using a gantry crane to lift the battery pack, the battery pack no longer sways, allowing workers to operate more calmly and precisely. They can carefully measure the dimensions of the cushioning cotton and accurately apply it to the bottom of the battery pack, ensuring the application meets production requirements. Throughout the entire operation, the workbench remains stable, providing workers with a safe and reliable working environment, greatly improving work efficiency and product quality. After the operation is completed, the operator grips the auxiliary handle 112 again and rotates the handwheel 111 counterclockwise, repeating the power transmission and component movement process to slowly lower the carrier 105, safely returning the battery pack to its initial position. Then, the operator carefully removes the battery pack from the carrier 105, completing one full workflow cycle.
