Quick opening and unloading device

The invention relates to a lifting device; in particular to a quick opening and closing type of structural uncovering device.

The lifting and unloading device of the present invention is generally widely used as a component for disassembling a bearing, an idler pulley, a pulley, and the like, which are closely matched with the shaft.

As for the typical type of loading and unloading device that can be seen at present, it can be read by the new patent of the "Simple Puller Structure" of the Republic of China Patent No. M373804. Its main structure includes the support base and the center screw set. The control screw, the arm claw and the adjusting cap, wherein the center screw set is a screw set on the support base, the arm claws are two pairs of state pivots on the support side, and the adjustment cap is arranged on the support seat. Wherein, the adjusting cap screw group is rotatably reversely rotated in the external thread portion of a central tube provided in the support seat to drive the control panel to be lifted and lowered, and the upper ends of the two arm claws are connected in the guiding chutes disposed on the two sides of the control panel.

In the prior art, the conventional lifting device type must be used to rotate the adjusting cap to drive the control panel to move up and down, thereby changing the height position of the upper end of the two arm claws, thereby changing the relative opening and closing range of the adjusting two arm claws (ie, Clipping state).

However, the above-mentioned conventional unloading device structure has found that there are still some problems and shortcomings in the practical application experience. For example, at least there are problems such as too many components and slow adjustment efficiency, among which the excessive parts are As the control panel has to be screwed together with an adjustment cap, the central tube of the support has to be externally threaded for the adjustment of the cap screw set, and the control disc and the adjustment cap must be further assembled through the fastener. In order to achieve a linkage state, the number of components is quite large, and the cost of manufacturing, processing and assembly is greatly increased. In the part of adjusting the slow lack of efficiency, because of the aforementioned conventional unloading device, the second The adjustment of the relative opening and closing width of the arm is achieved by the reverse rotation of the adjusting cap, so that the user cannot move the arm in the opening direction or move in the closing direction. After a slow displacement process can be achieved, which directly affects the efficiency and progress of the disassembly work.

Therefore, in view of the problems existing in the above-mentioned conventional loading and unloading device technology, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.
