[0002] The counter weight is a kind of rigid component that is balanced or stabilized by its weight, usually made of high-density materials such as metal, concrete, etc., in the form of regular blocks or sheets, and its core function is to provide controllable load to offset the inertia of motion, adjust the center of gravity or increase the stability of the system, commonly used in mechanical base, hoisting equipment, fitness equipment, etc. However, the traditional counter weight stacking process needs to rely on precise alignment and external pressure, and the angle deviation during operation may cause misalignment or slipping, which may cause accidental separation. When disassembling, it needs to be pulled or pried with tools, which is laborious and may damage the contact surface. Moreover, it is easy to misalign and slip during operation, and it is easy to loosen and separate in the process of carrying or vibration, which needs to be repeatedly calibrated and reinforced, and the safety risk is relatively large. In order to solve the problems mentioned in the above background, we propose a counter weight convenient to stack. SUMMARY

The limiting ring limits the spring, when the wedge-shaped block is above the wedge-shaped buckle, the spring rebounds to drive the wedge-shaped buckle and the clamping rod to move inward, and the wedge-shaped block is clamped and fixed. When the stacking needs to be released, the clamping rod is pulled outward, the wedge-shaped buckle loses the clamping with the wedge-shaped block, and the two block bodies are separated. Quick stacking and separation can be realized, the wedge-shaped block automatically slides into locking when stacking, which ensures stable and non-loose, and only needs to pull the clamping rod on both sides when unlocking, so that the two stacked counter weights can be quickly separated. Its advantage is that the operation threshold is zero, and the mechanical structure is simple and durable. It can be repeatedly disassembled without tools, which saves time and avoids the complexity of traditional bolt fixation, especially suitable for scenes with frequent weight adjustment.
