Abstract
The invention discloses a three-point locking type safety door lock for a pressure steam cabinet. The three-point locking type safety door lock comprises a lock catch assembly installed on a steam cabinet door frame and a spring bolt assembly installed on the steam cabinet door. The lock catch assembly is composed of a shell, a safety buckle and a pneumatic device. The spring bolt assembly is composed of a main spring bolt, a handle, an upper spring bolt, a lower spring bolt and a rotating shaft. The three-point locking type safety door lock has the beneficial effects that three-point locking is achieved, operation is convenient, when pressure exists in the steam cabinet, the lock is tightly buckled, the phenomenon that a door is opened under misoperation is avoided, and the effect of safety protection is achieved.
Description
Technical field
The present invention relates to technical field of kitchen wares, particularly relate to a kind of pressure steamer 3 locking type safety door latchs.
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 object of the invention is to the defect overcoming above-mentioned prior art, provide a kind of pressure steamer 3 locking type safety door latchs, to solve the problem proposed in background technology.
For achieving the above object, present invention employs following technical scheme:
A kind of pressure steamer 3 locking type safety door latchs, comprise the lock assembly be arranged on steamer doorframe and the dead bolt assembly be arranged on steam cabinet door, described lock assembly is made up of shell, safety buckle and pneumatic means.Described dead bolt assembly is made up of master lock tongue, handle, upper lock tongue, lower dead bolt and rotating shaft.
Described pneumatic means comprises cylinder and push rod, and described push rod top connects with safety buckle one end or contacts.Described safety buckle fixing in the enclosure by pin buckle activity.
Described safety buckle is provided with the bite matched with " V " v notch v on master lock tongue.When the push rod of cylinder upwards pushes up, drive safety buckle rotate, bite and master lock tongue " V " v notch v stuck.
Described master lock tongue is fixed in rotating shaft, and rotating shaft one end connects handle, and the other end connects connecting rod base.Described connecting rod base two ends are caught up with dead bolt/lower dead bolt respectively by upper connecting rod/lower link and are connected.
Described safety buckle is cross section is " Z " shape, and pin-and-hole is opened at its end.
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 further link pin promotes the dead bolt on connecting rod and connecting rod, and in the dead bolt hole this dead bolt is moved in its guide groove, entering in doorframe, steam cabinet door is locked by three dead bolts.
The center of gravity of safety buckle is in the left side of pin-and-hole, and under gravity, safety buckle can rotate counterclockwise around pin buckle; Under push rod promotes, can rotate clockwise.Cylinder air inlet 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 rotated under gravity, and the bite of upper end deflects to the left, 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 and rotates; the bite of upper end deflects to the right, if now swing handle unlocks, this bite can catch on " V " v notch v on master lock tongue; master lock tongue is caused not rotate; at this moment whole dead bolt assembly can not move, and 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 illustrates:
Fig. 1 is agent structure sterogram of the present invention;
Fig. 2 is lock assembly structure sectional view of the present invention.
Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below the invention will be further described:
A kind of pressure steamer 3 locking type safety door latchs, comprise the lock assembly be arranged on steamer doorframe and the dead bolt assembly be arranged on steam cabinet door, described lock assembly is made up of shell 1, safety buckle 2 and pneumatic means.Described dead bolt assembly is made up of master lock tongue 4, handle 5, upper lock tongue 6, lower dead bolt 7 and rotating shaft 8.
Described pneumatic means comprises cylinder 31 and push rod 32, and described push rod 32 top connects with safety buckle 2 one end or contacts.Described safety buckle 2 being fixed in shell 1 by pin buckle activity.
Described safety buckle 2 is provided with the bite 21 matched with " V " v notch v 41 on master lock tongue 4.When the push rod 32 of cylinder 31 upwards pushes up, drive safety buckle 2 to rotate, bite 21 is stuck with " V " v notch v 41 of master lock tongue 4.
Described master lock tongue 4 is fixed in rotating shaft 8, and rotating shaft 8 one end connects handle 5, and the other end connects connecting rod base 9.Described connecting rod base 9 two ends are caught up with dead bolt 6/ time dead bolt 7 respectively by upper connecting rod 10/ lower link 11 and are connected.
Described safety buckle 2 for cross section be " Z " shape, pin-and-hole 21 is opened at its end.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
