Clamp pressure cooker retractable structure

Abstract

The invention discloses a clamp pressure cooker retractable structure. The problem that a clamp is prone to self-restoration exists in an existing clamp-type pressure cooker commonly, in addition, a cooker body and a cooker cover can be pressurized under the condition that the cooker body and the cooker cover are not fully buckled by the clamp, and danger exists when the existing clamp-type pressure cooker is used improperly. The clamp pressure cooker retractable structure is characterized in that a first connecting rod located beside an opening button is fixedly connected with a sliding block, a sliding block spring is arranged between the outer end of the sliding block and the end of a sliding groove, and an arc-shaped transmission piece is arranged between the inner end of the sliding block and the opening button; a second connecting rod located beside a closing button is fixedly connected with a stop pin base, and a stop pin capable of moving up and down and self-resetting is installed on the stop pin base; a locking portion used in cooperation with the bottom of the closing button is formed on the upper portion of the stop pin. By means of the clamp pressure cooker retractable structure, the self-reset of the clamp is avoided, the pressure cooker can not be pressurized under the condition that the cooker body and the cooker cover are not fully buckled by the clamp, and the safety when the pressure cooker is used is improved.

Description

technical field [0001] The invention relates to a clamp type pressure cooker, in particular to an opening and closing structure of a clamp pressure cooker body and a pot cover. Background technique [0002] The opening and closing lid structure of pressure cooker has two kinds of screw-on type and clamp type at present. The pressure cooker with the screw-on opening and closing lid needs to be aligned when closing the lid, and the position when closing the lid is difficult to grasp, the operation is time-consuming, and the safety is relatively poor; in order to improve the safety of the pressure cooker, it is necessary to increase the safety of the pressure cooker. safety device. The pressure cooker with clamp-type opening and closing lid usually has the problem that the clamp is easy to reset itself, and the pot body and the lid can be pressed up without being fully fastened by the clamp, which is dangerous when used improperly; in addition, the existing The opening and c...
