Description

A kind of safety lock applied to pressure cooker

[technical field]

The invention relates to a safety lock applied to a pressure cooker.

[Background technique]

The existing pressure cooker is opened and locked by turning the lid, so when the user walks around with the pressure cooker, it is easy to make the lid and the pot body slide relative to each other, causing the lid to open. When the high-temperature food just cooked When the lid is suddenly opened, the high-temperature food that leaks out will easily injure the user, and children at home can easily turn the lid and open it, which is likely to cause danger; at the same time, the user may be distracted by other things and fail to If the pressure cooker is fully locked, and cooking with a pressure cooker that is not fully locked, the internal atmospheric pressure may also cause the lid to rotate, so that during the operation of the pressure cooker, the internal atmospheric pressure rotates and opens the lid, which is dangerous.

[Content of the invention]

The present invention overcomes the deficiencies of the above-mentioned technologies, and provides a safety lock applied to pressure cookers. A pressing safety lock switch is set, and the pot cover can be turned only by pressing the safety lock, thereby controlling the opening and closing of the pot cover, which greatly improves the The safety of using pressure cooker.

To achieve the above object, the present invention adopts the following technical solutions:

A safety lock applied to a pressure cooker, comprising a pot cover 1 and a pot body 2 joined by rotation, a slide 3 is provided on the pot cover 1, a lock pin 4 is provided at one end of the slide 3, and the pot The cover 1 is also provided with a spring 5 for pressing the lock pin 4 so that the lock pin 4 is locked on the upper edge of the pot body 2, the other end of the sliding plate 3 is provided with a limiting hole 6, and the handle of the pot cover 1 is provided with a The limit hole 6 cooperates with the connected limit pin 7, and the limit pin 7 breaks away from the limit hole 6 and when the pot cover 1 is turned, the lock pin 4 drives the slide piece 3 to slide outward.

The sliding sheet 3 is provided with a through hole 8, and the pot cover 1 is provided with an air valve fixing seat 9 under the position corresponding to the through hole 8, and the air valve fixing seat 9 is provided with a sliding sheet 3 in a non-sliding position. The airtight latch 10 pressed upwards along the air valve holder 9, the through hole 8 by the pot body 2 atmospheric pressure during the state.

The stopper pin 7 includes a thin shaft 71, one end of the thin shaft 71 is connected to a button arranged on the pot cover 1, and the other end of the thin shaft 71 is connected to a stop portion 72 that is larger in diameter than the thin shaft 71. The position-limiting hole 6 includes a positioning hole 61 for engaging the position-limiting portion 72 to block the sliding of the sliding sheet 3. The positioning hole 61 is connected to a sliding hole 62 whose width is smaller than that of the positioning hole 61. The sliding hole 62 is used for the position-limiting pin 7 is pressed and the stopper 72 breaks away from the positioning hole 61 and passes through the thin shaft 71 to realize the outward sliding of the sliding sheet 3 .

The upper edge of the pot body 2 is a pot body notch 21 extending outward and a pot body protrusion 22 extending outward, and the pot body notch 21 and the pot body protrusion 22 are arranged at intervals.

The pot cover 1 is provided with a pot cover projection 11 having the same shape as the pot body notch 21 and extending inward.

The beneficial effects of the present invention are:

The invention is provided with a push-type safety lock, and the pot cover can be turned to open or close the pressure cooker only by pressing the safety lock, which effectively prevents the pot cover from slipping when the user walks around with the pressure cooker, causing the pot cover to be opened suddenly and causing danger, and at the same time prevents children from easily When the safety lock is not pressed, the pot cover is completely locked and cannot be opened by turning it directly.

[detailed description]

A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:

As shown in Fig. 1, Fig. 2 and Fig. 3, a safety lock applied to a pressure cooker includes a pot cover 1 and a pot body 2 joined by rotation, the pot cover 1 is provided with a sliding sheet 3, and the sliding One end of the sheet 3 is provided with a locking pin 4, and the lid 1 is also provided with a spring 5 for pressing the locking pin 4 so that the locking pin 4 is locked on the upper edge of the pot body 2, and the other end of the sliding sheet 3 is provided with a limiting hole. 6. The handle of the pot cover 1 is provided with a limit pin 7 that cooperates with the limit hole 6. The limit pin 7 is separated from the limit hole 6 and when the pot cover 1 is turned, the lock pin 4 drives the sliding piece in 3 directions. slide outside. Wherein, as shown in FIG. 3 , the limit latch 7 includes a thin shaft 71, one end of the thin shaft 71 is connected to a button arranged on the pot cover 1, and the other end of the thin shaft 71 is connected to a button larger than the thin shaft 71. The limiting portion 72 of the diameter, the limiting hole 6 includes a positioning hole 61 for engaging the limiting portion 72 to block the sliding of the sliding sheet 3, the positioning hole 61 is connected to the sliding hole 62 with a width smaller than the positioning hole 61, the The sliding hole 62 is used for the sliding plate 3 to slide outward through the thin shaft 71 after the limiting bolt 7 is pressed and the limiting portion 72 is disengaged from the positioning hole 61 .

As shown in Figure 4, the pot cover 1 is provided with a pot cover bump 11 which has the same shape as the pot body notch 21 and extends inward. The mouth 21 and the pot body protrusion 22 extending outward, the pot body notch 21 and the pot body protrusion 22 are arranged at intervals.

When the pot cover 1 needs to be closed, the pot cover projection 11 of the pot cover 1 is closed to the pot body notch 21, and the button that is arranged on the pot cover 1 and connected with the limit latch 7 is pressed, and the limit of the limit latch 7 The position portion 72 moves downwards to break away from the positioning hole 61, the sliding hole 62 arranged on the sliding piece 3 can slide in the thin shaft 71, the lock pin 4 is in the unlocked state, and the user turns the pot cover 1 to make the pot cover projection 11 slide to The pot body bump 22 is closed, the positioning hole 61 on the sliding piece 3 is reset to the limit part 72 under the action of the spring 5, the button is released, the limit part 72 resets and engages the positioning hole 61, and the locking is arranged on the sliding piece 3 on the lock pin 4, thereby locking the pot cover 1; similarly, when the pot cover 1 needs to be opened, press the button that is arranged on the pot cover 1 and is connected with the limit latch 7, and the limit portion of the limit latch 7 72 moves downwards away from the positioning hole 61, so that the sliding hole 62 arranged on the sliding piece 3 can slide in the thin shaft 71, that is, the sliding piece 3 can slide outwards, so that the locking pin 4 is in the unlocked state, and the pot cover 1 Rotate to open the pressure cooker, effectively prevent the pot cover 1 from being opened when it is moving, and improve safety.

As shown in Figures 2 and 3, the sliding sheet 3 is provided with a through hole 8, and the pot cover 1 is provided with an air valve fixing seat 9 under the position corresponding to the through hole 8, and in the air valve fixing seat 9 Be provided with the air-tight plug 10 that is pressed upwards along the air valve fixing seat 9 and the through hole 8 by the pot body 2 atmospheric pressure when the sliding sheet 3 is in a non-sliding state.

But when the pot cover 1 is not rotated to the locked position, that is, the sliding piece 3 is not fully reset, and the limit part 72 is not engaged in the positioning hole 61, in the working state, the sliding piece 3 blocks the upward push of the pot body 2 by atmospheric pressure. The gas-tight plug 10 seals the air valve holder 9, so that steam overflows at the gas-tight plug 10, and the pressure cooker cannot work normally, and the user is also reminded that the pot lid 1 is not completely closed.
