Abstract
The utility model provides a pressure evaporates 3 locking formula safety locks in cabinet comprises hasp box, master lock tongue, handle, last spring bolt, lower spring bolt, pivot, connecting rod, connecting rod seat, link pin, has the release mechanism in the hasp box, and the lower stomidium of cylinder head feeds through through the steam pipe and in evaporating the cabinet. The hasp box is installed on evaporating the cabinet door frame, and the other part is installed on evaporating the cabinet door through the pivot. Closing back to the doorstep, rotating the handle, in the spring bolt got into the hasp box, upper and lower spring bolt evaporated the cabinet door and is locked in getting into the lock tongue hole of upper and lower door frame respectively. Rise when evaporating the cabinet internal pressure, steam promotes the ejector pin, the ejector pin promotes safe the knot and dies master lock tongue lock, evaporates the cabinet door and can not be opened. Evaporate the cabinet internal pressure when dropping to the safe pressure, the ejector pin drops under the effect of gravity with safe the knot, rotates the handle and has evaporated the cabinet door with regard to openable.
Description
Technical field
The utility model relates to technical field of kitchen wares, especially relates 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
The technical problem that the utility model solves is to provide a kind of novel pressure steamer door lock, to solve the problem proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Pressure steamer 3 locking type safety door latchs, comprise: safety buckle is arranged in keeper by safe pin buckle, push rod, cylinder, cylinder head composition pneumatic means is also arranged in keeper, handle and master lock tongue, rotating shaft, connecting rod base connect and rotate with handle, upper connecting rod, lower link one end connect upper lock tongue, lower dead bolt respectively, the other end is connected with connecting rod base respectively by left link pin, right connecting rod pin, it is characterized in that: have three dead bolts and pneumatic means;
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 beneficial effects of the utility model are, realize 3 lockings, easy to operate, when having pressure in steamer, lock by button dead, prevent maloperation from opening door, play security protection effect.

Fig. 2 is buckle structure schematic diagram of the present utility model.
Fig. 3 is pneumatic means schematic diagram of the present utility model.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model 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 is also replied 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 utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
