Said from page or leaf sheet and the hinge of the hinge that playbacks by fixing door leaf, be fixed in page or leaf sheet and hinge on the doorframe and overlap and form; Said hinge is made up of the shaft shoulder that axle core, a pair of helicoid of parcel axle core constitute, and the contact surface that said hinge cover is matched by the shaft shoulder that constitutes with a pair of helicoid, supplies the mandrel hole of hinge axle core insertion to form;
Said from locking mechanism by the deep-slotted chip breaker on the door leaf of right side and be articulated and connected at bolt mobile jib, sliding pin on this door leaf, be installed in L type link stopper, turn buckle and the position-limited rack of left side on the door leaf and form; Said sliding pin one end is fixed on the bolt mobile jib, the other end inserts in the deep-slotted chip breaker; The bolt mobile jib rotates in the scope of deep-slotted chip breaker; Said L type link stopper one right-angle side and left side door leaf are welded to connect, and the bolt mobile jib is shelved in the groove that L type link stopper and left side door leaf constitute and is horizontal level, and turn buckle is made up of the long-armed and galianconism that intersects vertically; The turn buckle door leaf hole dorsal part that is articulated and connected in the left side; Position-limited rack is positioned at door leaf hole, left side dorsal part and becomes place, certain angle of slope, and when turn buckle is long-armed when leaning on position-limited rack, the turning arm galianconism stretches out offside door fan hole outward, is positioned at the scope that the bolt mobile jib rotates; When the bolt mobile jib was positioned at the groove of L type link stopper and left side door leaf formation, the long-armed level that is of turn buckle fastened the bolt mobile jib.
Said doorframe crossbeam middle part is welded with door holder.
Said left and right door leaf framework is welded to connect by square steel pipe, and the upper, middle and lower baffle plate is a steel plate, is connected by steel net plate between the steel plate.
Compared with prior art, the building site personnel selection goods elevator protective door that has adopted the utility model to propose, have following advantage: doorframe and door leaf framework all adopt the square steel welding, and structure is more firm; Door leaf adopts the steel net plate than the large tracts of land ratio, when guaranteeing safety, has visuality, air permeability (reducing windage), and appearance is more attractive in appearance; Door hinge adopts from playbacking hinge and from blocking mechanism, solved traditional protective door and pass the problem of the sagging locking difficulty of door leaf of a specified duration because of the time, but and when the constructor neglects locking the door automatic blocking guaranteed safety, reduced maintenance cost, reduce construction cost.
Description of drawings:
Fig. 1 is the example structure sketch map that the utility model proposes.
Fig. 2 is that Fig. 1 embodiment is from playbacking the hinge arrangement sketch map.
Fig. 3 is that Fig. 1 embodiment is from the blocking mechanism structural representation.
Fig. 4 is Fig. 3 A-A sectional view.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: at an embodiment of Fig. 1～the utility model shown in Figure 3.Among the figure, a kind of building site personnel selection goods elevator protective door includes: doorframe 1, left-hand door fan 2, right door leaf 3, the hinge 4 that playbacks certainly, from blocking mechanism 6; Wherein:
Said doorframe 1 crossbeam middle part is welded with door holder plate 11, and door can only unidirectionally be opened.
Said left-hand door fan 2, right door leaf 3 frameworks are welded to connect by square steel pipe, and overhead gage 21, middle baffle plate 22, lower baffle plate 23 be steel plate, between the steel plate by steel net plate 24,25 connections.
Said from page or leaf sheet 41 and the hinge 42 of the hinge 4 that playbacks by fixing door leaf, be fixed in page or leaf sheet 51 and hinge on the doorframe and overlap 52 and form; Said hinge 42 is made up of the shaft shoulder 44 that axle core 43, a pair of helicoid of parcel axle core constitute, and the contact surface 54 that said hinge cover 52 is matched by the shaft shoulder 44 that constitutes with a pair of helicoid, supplies the mandrel hole 53 of 42 cores of hinge, 43 insertions to form.After door was open, the hinge shaft shoulder of face in the shape of a spiral rose along the helicoid that hinge overlaps, and removes the back door when external force and automatically resets according to gravity.
Said from locking mechanism 6 by the deep-slotted chip breaker on the door leaf of right side 61 and be articulated and connected at the bolt mobile jib 62 on this door leaf, sliding pin 63, be installed in L type link stopper 64, turn buckle 65 and the position-limited rack 66 of left side on the door leaf and form; Said sliding pin 63 1 ends are fixed on the bolt mobile jib 62, the other end inserts in the deep-slotted chip breaker 61; Bolt mobile jib 62 rotates in the scope of deep-slotted chip breaker 61; Said L type link stopper 64 1 right-angle sides and left side door leaf 2 are welded to connect; Bolt mobile jib 62 is shelved in the groove that L type link stopper 64 and left side door leaf 2 constitute and is horizontal level, and turn buckle 65 long-armed 68 is made up of with galianconism 67 what intersect vertically, the turn buckle 65 door leaf 2 hole dorsal parts in the left side that are articulated and connected; Position-limited rack 66 is positioned at left side door leaf 2 hole dorsal parts and becomes place, certain angle of slope; Present embodiment is 45 degree, and when turn buckle 65 long-armed 68 leaned in 66 last times of position-limited rack, the turning arm 65 galianconism 67 outer offside doors that stretch out are fanned 2 holes, are positioned at the scope that bolt mobile jib 62 rotates; When bolt mobile jib 62 was positioned at the groove of L type link stopper 64 and left side door leaf 2 formations, long-armed 68 of turn buckle 65 was level and fastens bolt mobile jib 62.When from elevator entering floor, portable bolt mobile jib rotates around hinge, and the driven rotary button rotates; With the rotation of bolt mobile jib, the long-armed of turn buckle leans on position-limited rack, removes the constraint of turn buckle pair of latches mobile jib; At this moment; The galianconism of turn buckle is overhanging to be gone out outside the door leaf hole, because the center of gravity of the long and short arm of turn buckle is in a long-armed side, so this invariant position of maintenance; When the bolt mobile jib puts down, touch the turn buckle galianconism and also rotate turn buckle, the bolt mobile jib rests groove that L type link stopper and left side door leaf constitute when interior, and the long-armed level that is of turn buckle fastens the bolt mobile jib.
The protective door of the utility model is made up of materials such as square steel pipe, angle steel and steel plates; Materials can use the remaining leftover pieces in job site; Have, characteristics such as making simple, easy-maintaining common, whole protection door weight 65kg, about 450 yuan of cost with material; And the turnover utilization rate is high, very easily universal at the construction field (site).This invention has representativeness in the waste wood utilization, aspect safe and practical, has opened up new thinking for subsequent technology innovation, environmental protection and energy saving, civilized construction, has guided new direction, also certainly will bring technological innovation further.
Combine accompanying drawing to describe the embodiment of the utility model above; The structure that embodiment provides does not constitute the restriction to the utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in this area.
