Description

A kind of rotating clamp jaw type pressure cooker

A kind of pressure cooker of the utility model especially relates to and a kind ofly controls clamp by rotation pot cover and pot body are locked pressure cooker with release.

Realize that by clamp and control device the pot cover of pressure cooker and the locking of pot body and the mode of release have a variety of at present.Pressure cooker is furnished with two clamps and radially is movably arranged on the locking and the tripper of the clamp that covers.Two clamps are configurations relatively with respect to the longitudinal axis of pot, and when the control device of clamp was positioned at locked position, clamp was suitable for banding just the cutting out on the position of the edge of pot, to lock a pot cover and a pot body hermetically.When the control device of clamp was positioned at unlocked position, clamp unclamped, and can open pot cover.

Chinese patent 95109146.8 discloses a kind of control device of opening and closing of pressure cooker container locking fixture, the control device of these anchor clamps comprises control piece, this control piece is along covering the direction that is substantially radially and installing versatilely according to predetermined stroke, when control piece moves, match with transmission arm, so that control moving radially of they.Control piece has special shaped surface, is particularly suitable for when control button moves, and the inclined surface effect relevant to anchor clamps moves radially anchor clamps.The traditional approach that control device cooperates with the inclined-plane becomes anchor clamps into radial motion by axially-movable closing moving between position and the open-part.

Above-mentioned control device mechanism complexity, it is not in place and make pot cover not closed that anchor clamps easily take place during locking, can't be locked on one's body the pot, thereby make clamping mechanism malfunctioning.

The purpose of this utility model is to provide a kind of easy to operate, rotating clamp jaw type pressure cooker that coupling mechanism force is big, safe and reliable.

The purpose of this utility model is achieved in that

A kind of rotating clamp jaw type pressure cooker, comprise a pot body, pot cover, pressure limiting valve assembly, safety valve complement, at least one pair of clamp that disposes radially movable installation relatively and control clamp are set on the pot cover to be opened and closed control device, this control device comprises handle and the spin-block that matches with handle, have deep-slotted chip breaker on the spin-block, one end of described clamp and pull bar is fixed, and the other end of pull bar is by in the deep-slotted chip breaker on the pull bar sleeve embedding spin-block.

This control device comprises the outer cover that is configured on the pull bar, has the gathering sill of guaranteeing that pull bar radially moves in the outer cover.

Described deep-slotted chip breaker two ends are positioned on the concentric circles of different radii, and its radius difference is the stroke of clamp radial motion.

This control device also comprises the toggle that is fixed on the outer cover, and a lateral process of toggle stretches into the valve body weight bottom of pressure limiting valve assembly, and the opposite side projection matches with the groove that is arranged on the handle bottom.

This control device also comprises the stopping valve assembly that is arranged on the pot cover, and the core bar of stopping valve assembly is just in time aimed at the lock hole that is provided with on the pull bar when clamp is in locked position.

Described handle, at its lower end is square, matches with the square hole at spin-block center.

Described clamp is preferably two pairs.

The utility model utilizes the rotation of handle, an end that makes pull bar is along moving in the deep-slotted chip breaker of different radii, the radial motion of other end pulling clamp, make clamp become radial motion by rotatablely moving closing moving between position and the open-part, thereby realize that clamp is to the locking of pot cover and pot body with unclamp.It is easy and simple to handle, and after handle rotate in place, clamp clamped pot cover and pot body, and by stopping valve and driving lever pull bar and handle was locked, and guaranteed the pressure cooker safe handling.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a pot cover upper controller vertical view in the structure shown in Figure 1;

Fig. 3 is an outer cover upward view in the structure shown in Figure 1;

Fig. 4 is a toggle action schematic diagram in the structure shown in Figure 1.

As figure, a kind of rotating clamp jaw type pressure cooker, comprise on pot body 2, the pot body 2 and have handle 1, pot cover 4, pressure limiting valve assembly 6, safety valve complement 19, be provided with two pairs of radially movable clamps of installing 13 of configuration relatively on the pot cover, the centre of pot cover 4 is provided with handle 8, handle 8 lower ends are square, the center that flexible connection matches with handle has the spin-block 9 of square hole 25, have deep-slotted chip breaker 21 on the spin-block 9, clamp 13 is fixing by rivet 12 with an end of pull bar 10, and the other end of pull bar 10 is by in the deep-slotted chip breaker 21 on the pull bar sleeve 15 embedding spin-blocks 9.Handle 8 and spin-block 9 are fixing with pot cover 4 by centre bolt assembly 16.

Pot cover 4 also has outer cover 5, has gathering sill 22 in the outer cover 5, and pull bar 10 embeds in the gathering sill 22, makes pull bar 22 to do radial motion along groove 22, can't rotate.

Deep-slotted chip breaker 21 two ends are positioned on the concentric circles of different radii on the spin-block 9, and its radius difference is the stroke of clamp radial motion.When pull bar 10 1 end motions during to the little position of radius, clamp 13 just in time is in locked position.

Be fixed with toggle 7 on the outer cover 5, a lateral process 71 of toggle 7 stretches into valve body 61 bottoms of pressure limiting valve assembly 6, and opposite side projection 72 matches with the groove 20 that is arranged on handle 8 bottoms.When clamp 13 was in locked position, because the deadweight of the valve body weight 61 of pressure limiting valve assembly 6, the projection 71 of compressing toggle 7 was upwards raised the projection 72 of toggle 7, just in time embeds in the groove 20 of handle 8 bottoms, and handle can't rotate.

Pot cover is provided with stopping valve assembly 6, when clamp 13 is in locked position, the core bar 61 of stopping valve assembly 6 is just in time aimed on the pull bar 10 lock hole 25 in the gathering sill 22 on the lock hole 24 that is provided with and the outer cover 5, pot inner pressure rises to a certain degree, promoting core bar 61 rises, enter lock hole 24 and lock hole 25, pull bar 10 can't be moved radially, guarantee the pressure cooker safe handling.

Be to improve the coupling mechanism force of clamp, preferably uniform two pairs of clamps are set.

The utility model operational circumstances is:

Pot cover 4 is covered on pot body 2, rotary handle 1 drives spin-block 9 and rotates, and the pull bar sleeve 15 on the pull bar 10 is moved along the deep-slotted chip breaker on the spin-block 9 21, because the constraint of the gathering sill 22 on the outer cover 5, pull bar 10 can only be done radial motion, and pulling clamp 13 is done radial motion, with pot cover 4 and 2 lockings of pot body, at this moment, the core bar 61 of stopping valve assembly 6 is just in time aimed at the lock hole 24 that is provided with on the pull bar 10, and the projection 72 of toggle 7 just in time embeds in the groove 20 of handle 1 bottom, and handle can't rotate.When pressure cooker heating back pot inner pressure rises to certain value, the core bar 61 of stopping valve assembly 6 is pushed lock hole 24 on the pull bar 10, pot cover firmly pins with a pot body, can't open.After heating finishes, stir toggle 7 with hand, projection 71 is with valve body weight 61 jack-up of pressure limiting valve assembly 6 and exhaust, and the projection 72 of toggle 7 also breaks away from the groove 20 of handle 1, and handle 1 is removed locking; Simultaneously because the pressure in the pot descends, and the core bar 61 of stopping valve assembly 6 can fall because of deadweight, thereby remove the locking to pull bar 10, handle 8 drives spin-blocks 9 backward rotation, makes clamp 13 radially break away from a pot body, opens pot cover 4 safe ready.
