Abstract
The utility model relates to an automatic door shutter with a damper apparatus, which is composed of a power part, a damping part, and a connecting rod part. The power part is mainly composed of an elastic resetting device; the damping part is composed of an internal and an external sleeves which are sheathed mutually, and the contacting surfaces of the internal and the external sleeves are coated with damping oil; the connecting rod device is composed of two connecting rods and fixing pieces. When the connecting rod device is used, the fixing pieces are respectively fixed on a door and a door frame, and the elastic force overcomes the damping force to close the door slowly after the door is opened. The elastic force and the resistance force of the utility model are adjustable, and the utility model is suitable for various housing doors.
Description
The utility model belongs to door closer-holder, particularly a kind of band damping automatic door closing device.
Door closer is used in daily life more and more widely as a kind of daily necessities.Existing automatic door closing device, mainly with machine driving, hydraulic damping is a technical characterictic, it is slowly shut door after door is pushed open.Chinese patent CN86201191U discloses a kind of door engine, it forms an oil closed cavity by base, end cap, damping block, oil sealing, screw, with blade and the base-mounted damping block that is welded on the torsion shaft oil pocket is divided into two parts, oilhole by the torsion shaft middle part is communicated with oil pocket, constitutes a closed damping oil circuit.In the upper end of torsion shaft, transmit the moment of torsion of plane scroll spring with shifting block, an end of plane scroll spring is installed in the groove of loam cake, promotes upper and lower push rod by torsion shaft, and door is closed automatically.Its complex structure, conditional request is many, cost is higher, be not suitable for popularization.
The purpose of this utility model provides a kind of simple structure, low, the easy-to-install band damping of cost automatic door closing device.
To achieve these goals, the technical solution of the utility model is such: it is made up of power section, damping portion, shaft portion.Power section mainly is one and places elasticity reset device in the inside and outside cover (as torsion spring etc.), in its two ends are individually fixed on the inner face of overcoat.Damping partly is made up of overcoat (or tapered sleeve) within a pair of mutual fit, wherein overcoat and fixture disjunctor.Interior overcoat center is installed with central axis, is coated with damping oil on the mating face between the interior overcoat.Under the dynamic action of torsion spring, interior overcoat overcomes damping force and slowly relatively rotates like this.Shaft portion is made up of two connecting rods and a fixture, connects with pin between them, on the central axis in left connecting rod one end is placed under the cover outer face.Left side connecting rod and interior cover are fixed.When cover rotates like this power is passed through the connecting rod transmission, make door open or close with respect to crossbeam.
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is an A-A sectional view of the present utility model;
Fig. 3 is the utility model scheme of installation;
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.The installation of this door closer-holder as shown in Figure 3, two fixtures 1 are screwed respectively on door top and doorframe crossbeam.The concrete structure of this door closer-holder as shown in Figure 1 and Figure 2.In the cover 7 and the mechanical torsion spring 8 of packing into during overcoat 6 fits, in the two ends of torsion spring 8 are stuck in respectively in the draw-in groove of the inner face of overcoat.Interior overcoat is had the central axis 5 fits location of trip bolt 9 by an end.Scribble damping oil on the contact surface of interior cover 7 and overcoat 6.When rotating an angle between the interior overcoat, the damping force in the elastic force of torsion spring 8 overcomes between the overcoat slowly resets like this.The tightness of adjustment screw 9, the closed intensity in can changing between the overcoat, thereby the size of adjustment damping force.
Left side connecting rod 3 connects by pin between right connecting rod 2 and the fixture 1.On the central axis 5 in the left end of left side connecting rod is placed under cover 7 outer faces.It is the circular hole 11 of circumferential arrangement that interior cover 7 end face edge have a circle, and its structure as shown in Figure 2.The relevant position of the arm of left side connecting rod 3 also has a circular hole.Latch 4 inserts on the left pitman arm in the circular hole and interior cover end face circular hole 11, and left connecting rod 3 is rotated synchronously with interior cover 7, and latch 4 inserts in and overlaps in the end face circular holes 11 in different, just can realize the adjustment to torsion spring 8 torque magnitude.
In another embodiment, circular hole 11 can be to be positioned at one of cover edge, 7 lower surface to enclose the recessed tooth that is circumferential arrangement, and the relevant position is provided with a double wedge on correspondingly left connecting rod 3 arms, and this double wedge and recessed tooth are meshing with each other, and also can realize the location of left connecting rod 3 and interior cover 7.
Like this, when door was opened, torsion spring 8 rotated, part kinetic energy is stored in the torsion spring, and after letting go, cover slowly resetted in the damping force in torsion spring 8 torsion overcome between the overcoat made, thereby drive left and right sides connecting rod and fixture, promote door and slowly close reposefully, realize the purpose of closing the door automatically.
The advantage that the utility model is simple in structure, cost is low, easy for installation, particularly Its torsion spring strength size is adjustable, thereby the strength of closing the door can be adjusted, so be fit to Different doors uses.
