Abstract
The invention provides a three-point locking type safety door lock for a pressure steam cabinet, which is composed of a lock catch box, a master bolt, a handle, an upper bolt, a lower bolt, a rotating shaft, a connecting rod, a connecting rod seat and a connecting rod pin, wherein a safety mechanism is arranged in the lock catch box, a lower end hole of a cylinder cover is communicated with the inside of the steam cabinet through a steam pipe, the lock catch box is installed on a door frame of the steam cabinet, and other components are installed on a door of the steam cabinet through the rotating shaft. After the door is closed, the handle is rotated, the bolt enters the lock catch box, the upper bolt and the lower bolt respectively enter bolt holes of an upper door frame and a lower door frame, and then the door of the steam cabinet is locked. When the internal pressure of the steam cabinet increases, steam pushes a push rod, the push rod pushes a safety buckle to lock the master bolt, and then the door of the steam cabinet can not be opened. When the internal pressure of the steam cabinet decreases to the safe pressure, the push rod and the safety buckle fall off under the action of gravity, the handle is rotated, and then the door of the steam cabinet can be opened.
Description
Technical field
The present invention relates to technical field of kitchen wares, especially relate to pressure steamer door lock.
Background technology
The door lock of steamer generally adopts one-point type locked, i.e. the mode of a dead bolt insertion snap close; For pressure-bearing type steamer, this mode has problems and is: because the pressure in steamer acts on door, can make a generation distortion, destroy the sealing of steamer, produce gas leakage; Also the steamer had adopts multiple spot locked, is generally carry out lock control respectively, inconvenient operation to each point.
Often have high-pressure high-temperature steam in steamer, if open steam cabinet door in this case, this high-temperature steam can spray, and may scald personnel, there is potential safety hazard.Current steamer door lock does not all have safety device usually, and when having pressure in steamer, door lock is also easily opened, and there is unsafe factor.
Summary of the invention
Technical problem solved by the invention is to provide a kind of novel pressure steamer door lock, to solve the problem proposed in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Pressure steamer 3 locking type safety door latchs are made up of snap close shell, safety buckle, safe pin buckle, push rod, cylinder, cylinder head, master lock tongue, handle, upper lock tongue, lower dead bolt, rotating shaft, upper connecting rod, lower link, connecting rod base, left link pin, right connecting rod pin;
Push rod, cylinder, cylinder head composition pneumatic means, snap close shell, safety buckle, safe pin buckle form snap close together with described pneumatic means, and snap close is arranged on steamer doorframe; Master lock tongue, handle, upper lock tongue, lower dead bolt, rotating shaft, upper connecting rod, lower link, connecting rod base, left link pin, right connecting rod pin composition dead bolt motion, the thin shaft portion on its shaft, is arranged on described dead bolt motion on steam cabinet door by this axle.
Shut steam cabinet door, rotate counterclockwise handle, master lock tongue rotates thereupon and enters snap close; Connecting rod base rotates and drivening rod pin thereupon, and the dead bolt that further link pin promotes on connecting rod and connecting rod enters in the dead bolt hole in doorframe, and steam cabinet door is locked by three dead bolts.
The center of gravity of safety buckle is in the side of pin-and-hole, and under gravity, safety buckle can be fallen to this inclination, and under push rod promotes, can rotate clockwise.Cylinder head air inlet port connects steamer inner chamber, and when steamer inner chamber is normal pressure, the inside and outside pressure reduction of cylinder is equal, and push rod falls under gravity; When push rod falls, safety buckle is toppled under gravity, and master lock tongue can rotate in snap close, realizes the lock and unlock of steam cabinet door.When pressure in steamer raises; Steam Actuation push rod moves upward; further push rod promotes safety buckle, the hook of safety buckle deflects thereupon; if now swing handle unlocks; this hook can catch on " V " v notch v on master lock tongue, causes master lock tongue not rotate, and at this moment whole dead bolt motion can not move; door can not be unlocked, and achieves safety protection function.
The invention has the beneficial effects as follows, realize 3 lockings, easy to operate, when having pressure in steamer, lock by button dead, prevent maloperation from opening door, play security protection effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is buckle structure schematic diagram of the present invention.
Fig. 3 is pneumatic means schematic diagram of the present invention.
Detailed description of the invention
In order to make actualizing technology means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
Pressure steamer 3 locking type safety door latchs are made up of keeper 1, master lock tongue 2, handle 3, lower dead bolt 401, upper lock tongue 402, lower link 501, upper connecting rod 502, rotating shaft 6, connecting rod base 7, right connecting rod pin 801 and left link pin 802; Described keeper 1 is made up of snap close shell 101, safety buckle 102, safe pin buckle 103, push rod 111, cylinder 112, cylinder head 113.
Keeper 1 is arranged on doorframe, and rotating shaft 6 is arranged on door; After shutting steam cabinet door, counterclockwise swing handle 3, master lock tongue 2 enters keeper 1, simultaneously, connecting rod base 7 rotates thereupon, drives right connecting rod pin 801 and left link pin 802 and promotes upper connecting rod 502 and lower link 501 respectively, and then promotes upper lock tongue 402 and lower dead bolt 401 enters in the dead bolt hole of upper and lower doorframe, at this moment, master lock tongue 2, lower dead bolt 401, upper lock tongue 402 at 3 places by door locking.
In door locking state, along with pressure in steamer raises, steam enters cylinder 112 by the air inlet of cylinder head 113, push rod 111 is by jack-up and promote safety buckle 102 and rotate, tilt, if at this moment clockwise direction swing handle 3, the hook above safety buckle 102 can catch on " V " v notch v above master lock tongue 2, handle 3 can not rotate, three dead bolts also just can not move, and can not unlock, and door can not be opened.When pressure drop in steamer is to certain value, push rod 111 falls, and safety buckle 102 also tilts under gravity, and " V " v notch v above the hook above safety buckle 102 and master lock tongue 2 can be thrown off, and now, can unlock, door can be opened.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
