Abstract
Disclosed is an accessory fitting for building construction, relating to the kinetic energy of doors. In order to provide a door automatically closing device which has the advantages of safe use, good effect and beautiful appearance, the utility model proposes an automatic hydraulic buffering closing device for doors comprising a restoring spring, an oil cylinder assembly with a hinging ear and a piston assembly with a hinging ear. The oil cylinder assembly comprises a hinging ear cover, a cylinder body and a end cover. The piston assembly comprises a piston rod, a bearing disc, a piston and a porous disc. The restoring spring and the piston assembly are arranged in the oil cylinder assembly, one end of the restoring spring abuts on the bearing disc, and the other end of the restoring spring abuts on the end cover.
Description
The utility model belongs to the accessory of building construction, particularly belongs to and the relevant device of door function.
And even existing unidirectional door adopts the flexible member of bow spring adhesive tape and so on can close automatically to reach door usually, this structure of closing door automatically is not only because of in that impact is big at closing time, produce high noisy and fragile door, and also the utmost point is not attractive in appearance.
The purpose of this utility model provides a kind of door safety shutoff of safe in utilization, effective, appearance looks elegant.
The utility model is by back-moving spring, the piston assembly of the hydraulic cylinder assembly of band hinge ear and band hinge ear is formed, hydraulic cylinder assembly is by hinge ear lid, cylinder body and end cap are formed, piston assembly is by the piston rod of band hinge ear, be installed in the bearing disc on the piston rod successively, piston, porous disc, plain cushion dish and nut are formed, one end of piston rod band hinge ear places outside the hydraulic cylinder assembly, its other end passes centre bore on the end cap and bearing disc mounted thereto, piston, porous disc, plain cushion dish and nut are installed in the hydraulic cylinder assembly together, back-moving spring is installed in the hydraulic cylinder assembly, the one end withstands on the bearing disc of piston assembly, its other end withstands on the end cap, at the trumpet type groove more than two of having in interior week of cylinder body and hinge ear lid link.Piston is the Elastic Circular taper, its bottom have more than two with porous disc on the corresponding through hole in hole.Has the throttle orifice that communicates with the piston base through hole on the bearing disc.
Because the utility model is made up of the hydraulic cylinder assembly of back-moving spring, band hinge ear and the piston assembly of band hinge ear, when the power of opening the door disappears, be delivered to behind the power cylinder assembly of closing the door automatically that back-moving spring produces, the piston assembly hydraulic cushion on doorframe and the door, an elder generation is slowly closed, once shut very soon then, avoided clashing, thereby reached the utility model purpose.
Fig. 1 is the utility model structural representation sectional drawing.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model is made up of the hydraulic cylinder assembly 2 of back-moving spring 1, band hinge ear and the piston assembly 3 of band hinge ear, hydraulic cylinder assembly 2 is made up of hinge ear lid 4, cylinder body 5 and end cap 6, between cylinder body 5 and the hinge ear lid 4 sealing mat 7 is housed, between cylinder body 5 and the end cap 6 sealing mat 8 and 9 is housed.Piston assembly 3 is made up of the piston rod 10 of band hinge ear, bearing disc 11, piston 12, porous disc 13, plain cushion dish 14 and the nut 15 that is installed on the piston rod 10 successively, the hinge ear end of piston rod 10 places outside the hydraulic cylinder assembly 2, the centre bore that the other end of piston rod 10 passes on the end cap 6 is installed in the hydraulic cylinder assembly 2 with bearing disc mounted thereto 11, piston 12, porous disc 13, plain cushion dish 14 and nut 15, back-moving spring 1 is installed in the hydraulic cylinder assembly 2, the one end withstands on the bearing disc 11 of piston assembly 3, and its other end withstands on the end cap 6 of hydraulic cylinder assembly 2.Cover the trumpet type groove 16 more than two of having in interior week of 4 links at cylinder body 5 and hinge ear, piston 12 is the Elastic Circular taper, its bottom have more than two with porous disc 13 on hole 17 corresponding through holes 18, have the throttle orifice 19 that communicates with through hole 18 on the piston 12 on the bearing disc 11.
When opening the door, piston rod 10 tensions, compression reseting spring 1 is protruding, produce gap 20 between bearing disc 11 and piston 12 bottoms, the hydraulic oil in the chamber that back-moving spring 1 is housed 21 of hydraulic cylinder assembly 2 are compressed and the through hole 18 through around the piston 12 and gap 22 between the cylinder body 5 and the gap 20 between bearing disc 11 and piston 12 bottoms, on the piston 12, the hole 17 on the porous disc 13 enter another chamber 23 of hydraulic cylinder assembly 2 fast.
After the power of opening the door disappears, piston rod 10 is in withdrawal in hydraulic cylinder assembly 2 under the effect of back-moving spring 1, make bearing disc 11 withstand on the bottom of piston 12, gap 20 disappears, and and then piston 12 pushed away to chamber 24 directions, gap 22 is disappeared, hydraulic oil in the chamber 23 is compressed and a hole 17 on porous disc 13, through hole 18 of piston 12 bottoms and the throttle orifice 19 on the bearing disc 11 enter in the chamber 21 slowly, make door at back-moving spring 1 and oil cylinder, piston assembly 2, slowly shut under 3 the hydraulic damping effect, when piston 12 when hydraulic cylinder assembly 2 end door are soon shut, the trumpet type groove 16 that hydraulic oil in the chamber 23 begins week in cylinder body 5 enters in the chamber 21 fast, and door is fastened under the effect of back-moving spring 1.
Claims (2)
1, a kind of door safety shutoff of forming by back-moving spring, it is characterized in that it also has the piston assembly of the hydraulic cylinder assembly and the band hinge ear of the band hinge ear that is contained in the back-moving spring two ends, hydraulic cylinder assembly is by hinge ear lid, cylinder body and end cap are formed, piston assembly is by the piston rod of band hinge ear, be installed in the bearing disc on the piston rod successively, piston, porous disc, plain cushion dish and nut are formed, one end of piston rod band hinge ear places outside the hydraulic cylinder assembly, its other end passes centre bore on the end cap and bearing disc mounted thereto, piston, porous disc, plain cushion dish and nut place in the hydraulic cylinder assembly together, back-moving spring places in the hydraulic cylinder assembly, the one end withstands on the bearing disc of piston assembly, its other end withstands on the end cap, the trumpet type groove more than two of having in interior week at cylinder body and hinge ear lid link, piston is the Elastic Circular taper, its bottom have more than two with porous disc on the corresponding through hole in hole, have the throttle orifice that communicates with the piston base through hole on the bearing disc.
2, according to the described door safety shutoff of claim 1, it is characterized in that sealing mat being housed at the cylinder body two ends.
