In following whole specification and claims, must understand the term of expression position and direction from the angle that stands on the distribution board people before who is installed on the vertical wall, for example " preceding ", " back ", " level " and " vertically ".

Each hinge means 10 (only showing one in the accompanying drawing) comprises the main body 11 of moulding of plastics materials, the rearwardly projecting hub sections 12 of cylindrical no screw channel 13 in main body 11 forms and has, this no screw channel 13 passes main body 11 from a side to a side along fore-and-aft direction.In its outside, hub sections 12 forms a pair of L shaped radial depressions 14 that is shaped by angle, and the corresponding a pair of formation thing 32 (Fig. 1) that is used for radially giving prominence to the horizontal through hole 33 of lid 30 cooperates.Schematically shown as the arrow A among Fig. 1 and B, hinge means 10 is connected with lid 30 in the hole 33 by hub sections 12 is coupled to.Depression 14 and projection 32 provide bayonet coupling mechanism, make the hinge means 10 can be fast and removably be fixed to and cover 30.

Each hinge means 10 has two pins of vertically aiming at 15,16, and door 40 rotatably is installed thereon.By one of pins of 15 expressions is fixedly pin or the pin integrally formed with main body 11, and another pin 16 is for being independent of the moving element (Fig. 6) that main body 11 forms.Movable pin 16 comprises vertical pin part 17 and perpendicular to the securing rod 18 of pin 17.Pin 16 is along being slidably received within the main body 11 with fixing pin 15 straight vertical axis x.

Movable pin 16 is inserted in the vertical guide groove 19 (Fig. 6) that is formed by main body 11 and aims at the through hole 20 of acquisition in the sidewall 21 of axis x and main body 11.Pin 17 modes with buckle are inserted in the guide groove 19, flexibly oppress tusk 22, and tusk 22 is used for maintaining pin 17 along guide groove 19.After the insertion, movable pin 16 is placed withdrawing position, in this position, the terminal 17a of pin 17 does not protrude in (Fig. 2) outside the hole 20.This position is to face to lean against on the backstop thing 23 by the other end 17b with pin to determine.

Be coupled to the buckle that obtains in the fork configuration 41 of door by fixing pin 15 and connect (Fig. 3, arrow C), door 40 steady pins preliminary and each hinge means are tied connect.So obtain preliminary assembling condition (Fig. 4), make door hole 42 vertically contiguous each hinge hole 20 and with the hole 20 of each hinge and return the pin of removing 17 and aim at.By manual lever 18, force movable pin 16 to slide then along the vertical direction shown in the arrow D among Fig. 4, make pin 17 be positioned at extended position thus, this position pin 17

pass aligning hole

20 and 42 the two.But by vertically separately and between the locking teeth 25 (only visible in the accompanying drawings) opened of elasticity, having prevented the sliding motion of movable pin 16 due to a pair of up to lever lock with respect to the main body 11 of door 40 and hinge around axis x swingle 18.At this position (Fig. 5), tooth 25 maintains bar 18, in case shotpin bolt 16 slides along the direction of axis x, prevents an accidental thus.Like this door is arrived each hinge means two difference held stationary.

For door assembly, at first two hinge meanss must be installed on the casing cover 30.Then by make fork 41 snap engagement fixedly pin 15 make 40 tentatively to be connected with each hinge means.Should be pointed out that under this state (as shown in Figure 4) that door is suspended on the shell but needs and more stably fix, because if open it by it is surpassed 180 ° from the make position rotation, will force pitch 41 separated from one another and unclamp fixedly pin 15.Yet as mentioned above, the temporary fixed state of Fig. 4 allows the operator to close movable pin 16 with respect to own and Men Eryan safe enough ground, opens excessive its except that not gate and can not fall.When the dismounting door, obtained identical fail safe.Recall from the hole 42 of door then after the terminal 17a of pin makes movable pin 16 releases making it to leave locking teeth 25 by swingle 18 at first, the operator vacates both hands and catches door and in the fixing buckle mode of pin 15 it is dismantled.

With reference to figure 8 and 9, the lateral aperture 33 of lid 30 and the screwed hole 35 of rear cabinet 34 are axially aligned at last.To be used for the screw 50 (Fig. 9) that lid 30 is fixed on the casing 34 is cooperated by the cylindrical channel 13 of hinge and the unthreaded hole 33 of lid, and screw in the screwed hole 35.When screwing out screw 50, can separate this lid from rear cabinet.Because the bayonet coupling between hinge and the lid, so removable screw can not cause hinge to separate from covering 30, therefore can not cause door to separate from covering 30.When carrying out this operation, the operator not should be noted that arrest lid and door the two with avoid they one or both of may fall and sustain damage.Door keeps being fixed to lid, therefore uses a hand to catch one of lid or door just to be enough to prevent that the two from having fallen.

In the embodiment shown in Fig. 8 and 9, hinge body 11 is formed for the abutment surface 13a of screw 50 heads 51 in cylindrical channel 13 inside.Similarly, two diametric hole 33 have rear end or the free-ended abutment surface 36 that is used for hub sections 12.When screw 50 was screwed in screwed hole 35 tightly, head of screw 51 prevented that hinge means 10 accidents are by the remainder dismounting from shell.Because it is integrally formed to be used for hinge is connected to two parts of mechanism and this of lid, so each hinge is only relevant with a screw.Screw number is few more, dismounting lose when cover they one of risk just more little.Screw 50 is allowed to make very compact hinge with respect to coaxial setting of hub sections 12 and bayonet coupling mechanism, and its main body is than little more with shown in the way of example in the accompanying drawing.

In addition, providing two pins or fixing point to guarantee that door still is stable when one of two pins (plastic material) destroy on each hinge means even will understand.
