Abstract
An adjustable-speed simple automatic closing device comprises a hollow casing unit, an automatic return unit and a rope. The casing unit is provided with a plurality of positioning stoppers which are protruded inwards from the inner surface of the casing unit. The automatic return unit arranged in the casing unit comprises a volute spring, an adjusting shaft used for adjusting elasticity of the volute spring and a positioning part capable of detachably interfering with one of the positioning stoppers so as to fix the adjusting shaft. The rope is arranged in the casing unit, a portion of the rope can be pulled out of the casing unit so that a restoration force can be accumulated in the volute spring, and when external force is canceled, the rope can be retracted automatically in a gradual decelerating manner by the aid of the restoration force and a damper. As the adjusting shaft is fixed by the aid of interference among the positioning stoppers and the positioning part, the number of components is reduced and the automatic closing device can be assembled easily.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Consult Fig. 2, be the preferred embodiment of the utility model energy speed governing plain type automatic closing device, it comprises a housing unit 2, and automatically replies unit 3, a rope body 4 and a stopper unit 5.Consult Fig. 3, be the stereogram after this preferred embodiment combination.
Consult Fig. 2, housing unit 2 comprises that one defines an accommodation space 211 and is the shell body 21 of cuboid, and the most individual inner surface of shell body 21 and position blocks 22 that protrude to accommodation space 211 of being formed at intervals, shell body 21 is formed with an opening 23 and a circular perforations 24 that communicates with accommodation space 211.In this preferred embodiment, position block 22 is integrally formed with shell body 21, forms its surface smoothing by the 21 inside punching presses of shell body.
Consult Fig. 2 and Fig. 4, automatically reply unit 3 and be arranged in the accommodation space 211, it comprises a scroll type spring 31, an adjustment axle 32, positioning piece 33 and a reel 34.
Consult Fig. 2 and Fig. 4, rope body 4 has a rope body free end 41 and a rope body fixed end 42, and rope body fixed end 42 is fixed on the reel 34, restricts body free end 41 outside opening 23 stretches out shell body 21, and can be pulled, and makes scroll type spring 31 store a restoring force.Execute an external force in rope body free end 41, part rope body 4 is pulled out outside housing unit, and interlock reel 34 rotations simultaneously, make scroll type spring 31 accumulate a restoring force.Disappear or the rope body 4 that do not have external force, the restoring force of scroll type spring 31 to make to pull out in shell body 21 outside is regained in the shell bodies 21 by external force, and, the body 4 of restricting is wound on the external surface of reel 34 by 34 rotations of interlock reel.
Consult Fig. 2 and Fig. 4, engine device 5 is provided with on the shell body 21 and is arranged in accommodation space 211 and protrudes from outside the opening 23 near opening 23 places and part, and it comprises a pulley 51, and a damper 52.Pulley 51 by rope bodies 4 rope body free end 41 and the local segment between the rope body fixed end 42 walk around and with body 4 interlocks of restricting.Damper 52 is connected with pulley 51 and rotates synchronously, and the stopper function that can slow down pulley 51 rotating speeds to single direction of rotation I (being the clockwise direction among Fig. 4) performance of pulley 51.
Consult Fig. 7, can be installed on the sliding door 6 by speed governing plain type automatic closing device, sliding door 6 can be drawn back or be shut along the track of a doorframe 7.Consult Fig. 7, sliding door 6 presents closure state, and rope body free end 41 is fixed on the doorframe 7.The user draws back sliding door 6 with hand (figure does not show), make sliding door 6 move to as shown in Figure 8 the state that draws back by closure state shown in Figure 7, at this moment, the body 4 of partly restricting also is drawn out outside shell body 21 thereupon, and then drive reel 34, and making scroll type spring 31 by not reached as shown in figure 10 as shown in Figure 9 by application of force state, scroll type spring 31 is contract state and accumulate a restoring force of bundle.When hand leaves sliding door 6 the time, the restoring force of scroll type spring 31 makes in the rope body 4 withdrawal shell bodies 21 of pulling out in shell body 21 outside, and is wound on the external surface of reel 34.Pulley 51 is rotated with clockwise direction in graphic by rope body 4 driven rotary, damper 52 performance stopper functions, rope body 4 reclaims in elder generation's slow mode in anxious back, when sliding door 6 is soon shut, slow down sliding door 6 speed of shutting gradually, and 6 accidents that clip to of avoiding taking place being pulled, 6 closure states that can be returned to as shown in Figure 7 of pulling at last.
By above explanation as can be known, pulling sliding door 6 o'clock, the body 4 of partly restricting is drawn out outside housing unit 2, and make scroll type spring 31 accumulate a restoring force simultaneously, again by the collocation of this restoring force and damper 52, when external force disappears, can make the rope body 4 of pulling out outside housing unit 2 with elder generation's slow mode automatic drawing back in anxious back.Cooperating supporting of keeper 33 to end section 331 again can interfere with the fixing axle 32 of adjusting mutually with arbitrary position block 22, and the real speed governing effect that has simple and easy adjustment rope body 4 to reclaim speed, and then, reach and reduce assembly and the effect that is easy to assemble, so can reach the purpose of this utility model really.
