The invention belongs to the technical field of clamps, and particularly discloses a gravity clamping type clamp which comprises a rack, a sliding frame, a connecting shaft, a connecting rod, clamp claws, a reset plate, a limiting plate and a limiting piece, wherein an accommodating cavity is formed in the top end of the rack, and movable grooves are formed in the front and rear ends of the rack;the sliding frame is movably arranged in the accommodating cavity, and a lifting ring is arranged at the top end of the sliding frame; the connecting shaft penetrates through the side end of the sliding frame; the two ends of the connecting shaft are exposed out of the movable grooves and hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the clamp claws;the clamp claws are hinged to the rack; and the reset plate, the limiting plate and the limiting piece are matched to limit the connecting shaft. By adopting the gravity clamping type clamp, the gravity clamping type clamp is simple in structure, low in cost and suitable for batch production, the connecting shaft is limited by means of cooperation of the reset plate, the limiting plate and the limiting piece, after the gravity clamping type clamp clamps an object and puts down the object, the clamp claws cannot be closed to clamp the object when the gravity clamping type clamp is lifted, andthe gravity clamping type clamp can be smoothly lifted.

    本发明属于夹钳技术领域,具体公开了一种重力夹紧式夹钳,包括机架、滑架、连接轴、连杆、钳爪、复位板、限位板以及限位件;机架顶端设有容置腔,机架前后两端均设有活动槽;滑架活动设置在容置腔内,滑架顶端设有吊环;连接轴穿设于滑架侧端,连接轴两端从活动槽露出与连杆一端铰接,连杆另一端与钳爪铰接,钳爪与机架铰接;复位板、限位板和限位件配合对连接轴限位。采用本发明技术方案,结构简单,成本低,适合批量生产,通过复位板、限位板和限位件配合对连接轴进行限位,在重力夹紧式夹钳夹取物品放下后,在提升重力夹紧式夹钳时不会使钳爪闭合将物品夹取,使重力夹紧式夹钳顺利提升。
