By with last lower internal door 15 back side circumferences on the alternative packing ring 35 of liner 48 butts that are provided with, absorb inside door 15 impact when inaccessible, can carry out its sealing well on the other hand.Than with alternative packing ring 35 on liner 48 butts that are provided with part more on upside and the downside respectively with the limit fin 38,39 up and down of liner 48 butts, sealing, can construct the contact relation between packing ring 35 and the liner 48 more reliably, can improve sealing.In addition, also inboard by the liner 48 that is provided with on than inside door 15, and to the wing liner 49 in the limit that alternative packing ring 35 stretches, can form the space K that surrounds by the wing liner 49 in liner 48, packing ring 35 and limit, air layer in the K of this space can prevent that extraneous gas from entering, and significantly improves sealing.
Because inside door 15 by outside plate 41, inner panel 42, make the heat-insulating resin system doorframe 43 of two plates and the space that surrounds by these outside plates, inner panel and doorframe in the heat-barrier material 44 that disposes constitute, so can heat isolate the opening 14 of each primary storage facility, and owing on doorframe 43, be provided with first ditch 45 that liner 48 is installed and second ditch 46 that the wing liner 49 in exhausted limit is installed, so can realize double seal configuration by liner 48 and the wing liner 49 of alternative packing ring 35 and limit, further improve heat-proof quality as inside door.
The locker 20 of second embodiment of the invention is described to Figure 12 according to Fig. 9.Locker 20 constitutes by stainless steel accessory 65, and this stainless steel accessory has the metal lockmaking that claw 60 fixing on hinge one side (being that non-axle is supported side) the axle accessory 65 that upward rotation is provided with freely is not set in inside door 15 sides and buckles 50; In the case foundry goods system axial region 68 that is provided with on each little opening 14 part of hinge one side is not set with having in the hot box main body 2.
Snap close 50 supports metal fixed head 51 such as the stainless steel installed on the side of sides and the metal operating bodies 56 such as stainless steel that rotation is supported freely on this fixed head 51 to constitute by being positioned at the non-axle of inside door 15, and fixed head 51 has the axle 52 that pivotal support uses, the protection ring 53 and the fixing hole 54 of protection axle 52.Operating body 56 is by handle 57 and have by the action bars 58 of the wrist 59 of axle 52 pivotal support and constitute.Existing at claw 60 fixing on the axle described later accessory 65 with when snap close 50 uses when inaccessible (inside door 15) on this action bars 58, becoming the window 61 that same position ground forms with the fixing hole 54 of fixed head 51.Claw 60 makes on action bars 58 the claw-like stainless steel layer 62 that forms and at the duplex of this claw-like part top casting ground foundry goods thing 63.
The lock operation of locker 20 is described simply.At first inaccessible inside door 15 is up to desirable position.In the inside door of this state, rotating latch 50 is till being the position of the angle about 70 degree with fixed head 51 in face of self.And be the center with axle 52, rearward push handle 57, till the axial region 68 contacted states of the front end of its claw 60 and axle accessory 65.From this state, begin the snap close operation of so-called inside door 15.Promptly, if along the inboard further push handle 57 rearward of the flexure planes that form that goes up of claw 60, the mode of the surface of this axial region 68 to move along flexure plane, produce revolving force according to lever principle, the axle of locker 20 is 52 near axial region 68, and each inside door rearward pushes the blocking direction of inside door 15 (promptly to); Make inside door 15 be firmly held in blocking direction.
By making claw 60 make the duplex of stainless steel layer 62 and foundry goods layer 63, then when improving, can increase its length and thickness direction distance as snap close 50 intensity.In addition and since axial region 68 form cylindric, so improved its intensity than tabular cutting-out folded up portion 80.And when snap close 50 made its claw 60 be fixed in the axial region 68 of an accessory 65, revolving force utilized lever principle that inside door 15 is changed to the power of blocking direction pushing.At last, because the difference in size setting claw length T between the radius of turn R1 of the bearing surface front end by claw 60 and axial region 68 and the terminal radius of turn R2, so that inside door 15 is pushed to blocking direction, so it is possible increasing the torque of 50 pairs of axial regions 68 of snap close, promptly use littler power that snap close 50 is in the lock state, improved as the locker usability.
