Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
As shown in Figure 1, a kind of high-tension switch cabinet Structure of safety door lock, comprises cabinet 1, the cabinet door 2 be rotatably connected on cabinet, arranges corresponding cabinet door lock, to realize the locking of cabinet door in the unsettled side of cabinet door.Particularly, cabinet door lock comprises the axle sleeve 3 being laterally fixedly installed on cabinet door surface, and the axis of certain axle sleeve should perpendicular to cabinet door surface.Be rotationally connected a driving shaft 4 in axle sleeve, the inner of this driving shaft is stretched in cabinet door through cabinet door surface.Be understandable that, we can arrange corresponding driving shaft support 21 in the inner side of cabinet door, to make driving shaft the inner stretched in cabinet door be able to reliable support.As shown in Figure 2 and Figure 3, driving shaft stretches into the inner in cabinet door also needs be fixedly installed a circular driving-disc 41, the side of this driving-disc arranges upper and lower two arc guide barrels 411, the through driving-disc two sides of arc guide barrel, arc guide barrel one end is opening end, the other end is locking end, and the distance in arc guide barrel and driving-disc axle center increases progressively from opening end to locking is linear.In addition, the both sides being up and down positioned at driving-disc in cabinet door also slidably connect the upper push-rod 5 that upwards extends vertically and respectively vertically to the lower push-rod 6 of downward-extension, it should be noted that, we can arrange several pusher bar support 51 on cabinet door, pusher bar support is arranged corresponding pilot hole, upper and lower push rod then fits in the pilot hole of pusher bar support, thus upper and lower push rod can be moved up and down.In addition, the lower end of upper push-rod and the upper end of lower push-rod need the roller shaft 52 of a transverse direction respectively, roller shaft is arranged a roller 53, roller rolling on upper push-rod is connected in the arc guide barrel above driving-disc, thus in the arc guide barrel that the lower slide of upper push-rod is connected to above driving-disc; Correspondingly, the roller rolling on lower push-rod is connected in the arc guide barrel below driving-disc, thus in the arc guide barrel that the upper end of lower push-rod is slidably connected at below driving-disc.Further, we also need arrange a dead bolt 54 in the bottom of the upper end of upper push-rod and lower push-rod respectively, and cabinet arranges lockhole 11 in the position of corresponding two dead bolts simultaneously.Like this, when cabinet door is in opening, roller on upper and lower push rod is positioned at the opening end of arc guide barrel, when we need locking cabinet door, can driving shaft be rotated forward thus drive driving-disc to rotate, because the distance in the arc guide barrel on driving-disc and driving-disc axle center increases progressively from opening end to locking is linear, therefore, arc guide barrel correspondingly can promote upper and lower push rod and move respectively to upper and lower both direction, and now the dead bolt of upper and lower push rod end can enter on cabinet to be lived by cabinet door lock in corresponding lockhole.Otherwise, when cabinet door opened by needs, we can rotate backward driving shaft thus drive driving-disc to rotate backward, arc guide barrel can correspondingly pull upper and lower push rod to move respectively to upper and lower both direction, now the dead bolt of upper and lower push rod end can exit corresponding lockhole on cabinet, to be the unblock of cabinet door.Be understandable that, two arc guide barrels up and down on driving-disc should be Central Symmetry and arrange
For the ease of the rotation of driving shaft, we can be arranged integratedly along the connection-peg 42 of Axis Extension on the outer face of driving shaft, the handle 7 of a sheathed rotation on the driving shaft simultaneously.As shown in Figure 2, Figure 4 shows, handle comprises a barrel-shaped end cap cover 71 and is connected to the handle bar 72 of end cap cover side, and the inner bottom surface of end cap cover arranges the connection slot 73 with connection-peg clamping.Like this, when both direction pulls handle bar up and down for we, the positive and negative both direction of driving axial can be driven to rotate.
In order to improve safety, prevent the random unlatching cabinet door of non-working person, we also just can arrange a radial lockpin hole 31 to the axis place of axle sleeve on the upside of the periphery of axle sleeve, and this lockpin hole extends internally thus through to drive shaft surface.In addition, the periphery of driving shaft radially arranges the angle of rotating required for handle when namely two central angles that along the circumferential direction separated locking hole 43, two locking holes are corresponding on the periphery of driving shaft equal locking and open cabinet door on the cross section of corresponding lockpin hole.In addition, need to arrange the lock pin 32 that can be stretched into locking hole in lockpin hole, certainly, be understandable that, the diameter of lockpin hole and locking hole can be equal.Further, the outside of axle sleeve needs a sheathed sheath 33, thus lock pin can be avoided to drop out in lockpin hole.Correspondingly, now the end cap cover of handle is set on sheath, and is embedded at end cap cover and the position of corresponding lock pin on the medial surface that sheath is fitted the magnetic block 74 that a permanent magnet makes.Like this, when cabinet door is in locking states, we can by handle except lower collection, lock pin is now positioned on driving shaft along second of forward direction locking hole, and the length of lock pin should be greater than the degree of depth of locking hole, thus the upper end of lock pin is made to be positioned at the lockpin hole of axle sleeve, that is, lock pin is connected across between locking hole and lockpin hole, is in lockup state between driving shaft and axle sleeve.Non-working person, because do not have dedicated handle of the present utility model, therefore cannot utilize the general utility tool rotating driveshaft of spanner and so on to be opened by cabinet door, thus guarantee safety.When we need to open cabinet door, handle can be overlapped again and be set on sheath, and guarantee that the magnetic block in handle end cap cover is just positioned at the top of lock pin, the connection-peg simultaneously on driving shaft and the connection slot on handle should reliably be connected together.Lock pin now moves up and enters in lockpin hole completely under the effect of magnetic block suction, thus makes to remove lockup state between driving shaft and axle sleeve.It should be noted that, for the ease of determining direction and position, we make the handle bar of handle handle when cover is set on sheath just be in level by reasonably designing, and like this, we can pull handle bar downwards makes driving shaft rotate backward.Arc guide barrel now on driving-disc can pull upper and lower push rod to move reset to upper and lower both direction, and the dead bolt of upper and lower push rod end exits the lockhole on cabinet, makes cabinet door be in opening.Meanwhile, magnetic block is followed handle and is rotated together and progressively form dislocation away from lock pin, thus the suction of lock pin at vertical direction is progressively reduced, therefore lock pin moves down under the effect of self gravitation, and the lower end of lock pin can be resisted against on the periphery of driving shaft.When upper and lower push rod resets completely, first locking hole on driving shaft just turns to just to the position below lock pin, lock pin now can enter in this locking hole under the effect of self gravitation, thus make driving shaft again be in lockup state, now can remove handle, thus guarantee that cabinet door is in opening.In like manner, when needs again locking cabinet door time, we again can overlap upper handle on axle sleeve, and guarantee that the handle bar of handle remains on level, like this, magnetic block in handle end cap cover is still just positioned at the top of lock pin, thus lock pin is upwards picked up, make axle sleeve and driving shaft remove lockup state, we upwards can pull handle again, thus making cabinet door again be in locking states, lock pin is then again in screens second locking hole on the driving shaft.Be understandable that, sheath and driving shaft can adopt nonferromugnetic material to make, in order to avoid magnetic block produces magnetic effect to it.Wherein sheath preferably can adopt copper, plastics make, and driving shaft then preferably can adopt aluminium alloys to make.
In addition, we also can arrange one and along the circumferential direction extend and the arc chute 44 being communicated with two locking holes on the periphery of driving shaft, the width of this arc chute equals the diameter of locking hole, thus make the sidewall of two of arc chute sidewalls and two locking holes be formed tangent, that is, the half sidewall of locking hole opening part is through by arc chute, second half sidewall is retained, and two of arc chute sidewalls can be transitioned into second half sidewall that two locking hole opening parts are retained smoothly.In addition, we should make the length of lock pin be greater than the degree of depth of lockpin hole, and the difference of lock pin length and the lockpin hole degree of depth is less than the degree of depth of arc chute.Like this, when lock pin enters in lockpin hole, lockpin hole can be stretched out in its lower end, but the length of stretching out lockpin hole is less than the degree of depth of arc chute.Therefore, when cabinet door needs mutually to change between opening and locking states, we first overlap upper handle on sheath, by the magnetic block in handle, lock pin is drawn in lockpin hole, the length of stretching out lockpin hole due to now lock pin lower end is less than the degree of depth of arc chute, we still can pass through handle rotating driveshaft, and lock pin lower end now is then moved in arc chute.When drive shaft turns puts in place, lock pin is just positioned at the top of another locking hole, thus the half sidewall retained by this locking hole opening part stop location, lock pin can enter in this locking hole exactly by driving shaft locking.Further, we also can arrange tapering at lock pin near one end of locking hole, enter in locking hole to be conducive to lock pin.
The position on sheath is set to for the ease of position fixing handle cover exactly, the cross section of connection-peg can be set to regular polygon by us, thus make connection-peg form positive multi-edge column-shaped, and the limit number of this regular polygon should equal 360 divided by the corresponding on the driving shaft central angle number of degrees of two locking holes.Such as, when the rotational angle of handle---when the central angle that namely two locking holes are corresponding is on the driving shaft 60 degree, the limit number of regular polygon equals 6.Like this, when taper knob is set on sheath, its handle bar should be in level, and if handle misplaces, its dislocation angle be 60 degree, therefore staff can be very easy to find, thus effectively can avoid the arranged in dislocation of handle.In addition because the rotational angle of handle is just 60 degree, therefore, the connection-peg state that handle rotates the positive multi-edge column-shaped of rear drive shaft end still maintains the original state, like this, when again taper knob being set on sheath, still the handle bar of handle can be made easily to remain on level, avoid producing between the magnetic block on handle and lock pin misplacing.
Finally, as shown in Figure 5, we also can arrange the bracing strut 22 of two lateral arrangement in cabinet door near upper push-rod place, the locking bar 8 of a transverse direction that two bracing struts are slidably connected, locking bar arranges dead bolt 54 in the one end near cabinet, cabinet then arranges lockhole 11 in the position of corresponding dead bolt, upper push-rod arranges an oblique push block 9 in corresponding locking bar position, oblique push block has one and progressively drive inclined-plane 91 near the locking bar of upper push-rod from bottom to up, locking bar is pressed on locking bar driving inclined-plane away from one end of cabinet.When we need to close locker door, handle drives upper push-rod moves, the locking bar on oblique push block now drives inclined-plane can promote locking bar transversal moving forward, and the dead bolt of locking bar front end enters in lockhole corresponding to cabinet, thus can increase the reliability of cabinet door locking.Certainly we also need to arrange corresponding locking bar resetting-mechanism, to move down reset hour locking lever at upper push-rod synchronously can retreat reset.Particularly, we can arrange an annular retaining ring 81 in locking bar part between two bracing struts, and a sheathed stage clip 82 on locking bar simultaneously, one end of stage clip compresses annular retaining ring, and the other end then compresses the bracing strut near cabinet.Like this, when we need to open cabinet door, handle drives upper push-rod moves down, and locking bar now can retreat and reset until annular retaining ring is resisted against on the bracing strut away from cabinet under the effect of stage clip, thus makes cabinet door unlocking state.
