Clamp type pot cover opening and closing structure

Abstract

The invention discloses a clamp type pot cover opening and closing structure. The clamp type pot cover opening and closing structure comprises a pot cover, clamps, guide posts, a lifting handle, a turn-button, a grooved pulley and a safety valve; one end of each clamp is rotatably connected with the pot cover; the other end of each clamp is connected with the corresponding guide post; the clamp type pot cover opening and closing structure also comprises a fixing plate and an opening stop rod; an accommodating cavity is formed in the lifting handle; the fixing plate is positioned in the accommodating cavity and the grooved pulley is rotatably arranged on the fixing plate; limiting grooved holes and a limiting through hole are formed in the fixing plate; eccentric grooved holes, a large grooved hole and a small grooved hole are formed in the grooved pulley; the guide posts penetrate through the limiting grooved holes and extended into the eccentric grooved holes; the lower part of the opening stop rod is positioned in the limiting through hole and forms a limiting platform which is pressed against the safety valve; the upper part of the opening stop rod is positioned in the large grooved hole and the small grooved hole; the turn-button is rotatably arranged on the lifting handle and is connected with the grooved pulley; the turn-button is provided with an opening position and a closing position. Through the structure, all parts are centralized to the lifting handle in a unified manner so that the parts are matched more closely; the operation is smoother; the problems of looseness and the like cannot be caused after long-term use; the occupied space is reduced; the production cost is reduced.

Description

technical field [0001] The invention relates to a clamp type pot cover, in particular to a clamp type pot cover opening and closing structure. Background technique [0002] The existing clamp-type pot cover generally promotes the clamp to move outward or inward by rotating the handle to achieve the purpose of locking or loosening the pot body, and in order to avoid the accidental opening of the pot cover during cooking risk, the clamps of the existing clamp-type pot lids will be locked by the opening mechanism during the high-pressure cooking process. At this time, even if the rotating handle is operated, the clamps cannot be opened, which is safer when used. However, when the existing clamp-type pot cover is locked, unlocked, and locked by the anti-opening mechanism, the cooperation between the various parts is not tight, and it often occurs that the clamp cannot be locked in place, and the operation is not smooth during use. Problems such as looseness between the parts af...
