Embodiment Construction

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] In the opening and closing structure of the clamp pressure cooker as shown in the figure, the lid 2 is used in conjunction with the pot body 1, and there is a sealing ring 30 between the pot body 1 and the pot lid 2. The pot cover 2 is equipped with a self-locking safety valve 3. The upper surface of the pot cover 2 is fixedly connected to the gear shaft 4 located at the center of the pot cover and the linear chute 5. The gear shaft 4 runs through the chute 5. The gear 6 above the chute is axially connected, and the chute 5 is provided with a first connecting rod 7 and a second connecting rod 8 that reciprocate linearly along the chute. The inner ends of the first link 7 and the second link 8 both form a rack 9 for meshing with the gear 6, and the outer ends are connected to the clamp 10, which is realized by the movement of the first link...

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 body and a lid of the clamp pressure cooker. Background technique [0002] At present, there are two types of opening and closing lid structures of pressure cookers: screw-on type and clamp type. The pressure cooker with the screw-on opening and closing lid needs to align the position when the lid is closed, and the position when the lid is closed 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 additionally prevent misoperation safety device. Pressure cookers with clamp-type opening and closing lids generally have the problem that the clamps are easy to reset by themselves, and the pot body and the lid can be pressed up without being fully buckled by the clamps, which is dangerous when used improperly; in addition, the existing ...
