Description
Technical field
The utility model relates to a kind of snubber that closes.
Background technology
The notification number of China national Department of Intellectual Property 22 bulletin mandates October in 2003 is that the patent of invention of CN1125229C discloses a kind of lamp tube type noiseless door closer, this door closer comprises swing arm and preceding, rear support, swing arm is by body, place the interior adjusting rod that joins by the protecgulum of screw and body of body, form with the join extension spring of rear end band aft hook and snubber of adjusting rod, swing arm is by the hook and the rear support snapping at extension spring rear portion, preceding bearing is provided with and can goes up, down, a left side, the right fixed rack of regulating, the front end of swing arm with active being fixed on of spiral shell inspection before in the slide rail of bearing.This door closer structure more complicated, manufacturing cost is higher relatively, and same door closer can not adapt to a various dynamics of closing, for example cushioning the less door closer of dynamics is installed in when closing on the door door with stronger dynamics, because closing a speed inadequately, the buffering dynamics will at this moment will send the sound that closes door than comparatively fast.
Summary of the invention
The purpose of this utility model provide a kind of easy for installation, simple in structure, manufacturing cost is lower closes a snubber, a this snubber that closes can make the relatively more consistent closing velocity of a maintenance in different closing under the pressure.
For this reason, the snubber that closes that the utility model provides comprises installing rack and snubber body, and the snubber body comprises headgear and overcoat, and headgear and overcoat are pegged graft, headgear and overcoat also are equipped with the screens mechanism that prevents that both break away from, and the relative overcoat of headgear has specific flexible scope; Have internal thread on the headgear inwall, also be provided with spring, turning cylinder is threaded with headgear, turning cylinder has the external screw thread with the internal thread coupling, insert in the sliding sleeve turning cylinder rear end, turning cylinder can rotate relative to sliding sleeve, and sliding sleeve is arranged in the overcoat, and the relative overcoat of sliding sleeve is circumferentially fixing along the sliding sleeve length direction.
The utility model closes a snubber by headgear, overcoat and be arranged at headgear and overcoat in buffer constitute, because the utility model buffer adopts the screw-internal thread fit in screw rod and the headgear, headgear is further exerted pressure to screw rod in the process that is extruded, because screw rod can rotate relative to sliding sleeve, screw rod rotates and impels headgear to move down along the tendency of screw thread relative to headgear in this process, because being the mode with threaded engagement, headgear mobile limit, therefore to close a pressure be greatly no matter headgear is subjected to or the little headgear that can both impel slowly moves, and the be stressed influence of size of its translational speed is very little; Spring in the headgear can make and close a snubber promote headgear when being closed pressure in addition, makes its reinstatement.And it is simply compact that the utility model closes a buffer structure, even can make the common lighter size, very convenient installation, and a whole in addition snubber that closes can adopt the plastics of less expensive to make, so manufacturing cost is relative also lower.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model closes a snubber and comprises installing rack 1 and snubber body 2, snubber body 2 comprises headgear 3 and overcoat 4, headgear 3 is pegged graft with overcoat 4, headgear 3 also is equipped with the screens mechanism that prevents that both break away from overcoat 4, and headgear 3 relative overcoats 4 have specific flexible scope; Have internal thread 5 on headgear 3 inwalls, also be provided with spring 6, turning cylinder 7 is threaded with headgear 3, turning cylinder 7 has the external screw thread with internal thread 5 couplings, insert in the sliding sleeve 8 turning cylinder 7 rear ends, turning cylinder 7 can rotate relative to sliding sleeve 8, turning cylinder 7 is made of screw rod 9 and slide bar 10 two parts, have external screw thread on the screw rod 9, screw rod 9 is threaded with headgear 3, one end of slide bar 10 and sliding sleeve 8 are pegged graft, be marked with resistance oil in the sliding sleeve 8, slide bar 10 is with sealing ring 13, sealing ring 13 can prevent that resistance oil from leaking, sealing ring 13 cooperates with sliding sleeve 8 inwalls, the other end of slide bar 10 contacts with screw rod 9 end faces, screw rod 9 cooperates with slide bar 10 rubbing surfaces, screw rod 9 ends have rubber ring 11 in the present embodiment, slide bar 10 ends have anti-skidding projection 12, the rubber ring 11 of screw rod 9 and anti-skidding projection 12 tight fits of slide bar 10, sliding sleeve 8 is arranged in the overcoat 4, and sliding sleeve 8 relative overcoats 4 are circumferentially fixing, be that sliding sleeve 8 can not rotate relative to overcoat 4, sliding sleeve 8 cooperates realization by the raised line 20 that is arranged at sliding sleeve 8 ends with the draw-in groove 21 of overcoat 4 inner bottom parts with the fixing of overcoat 4.
As Fig. 2, shown in Figure 4, screw rod 9 has steel ball cushion cap 15 near an end of spring 6, and steel ball 14 is arranged between steel ball cushion cap 15 and the spring 6.Rotation process medi-spring 6 and steel ball 14 frictions at screw rod 9 because the frictional force that both produce is less, can make the rotation of screw rod 9 more smooth and easy.
As Fig. 2, shown in Figure 3, the formation that prevents the screens mechanism that headgear 3 and overcoat 4 break away from is: headgear 3 outer peripheral faces are provided with screens projection 16, overcoat 4 inwalls are provided with the chute 17 with screens projection 16 couplings, chute 17 is provided with the limited block 18 of smooth excessiveness, screens projection 16 can slippage in chute 17, makes headgear 3 relative overcoats 4 possess certain flexible scope.
As shown in Figure 1, snubber body 2 is pegged graft with installing rack 1, snubber body 2 relative installing racks 1 have specific flexible scope, installing rack 1 upper bumper body 2 rear ends are provided with screw thread member 19, screw thread member 19 and installing rack 1 threaded engagement, as long as the user can turn screw thread member 19 and make it promote snubber body 2 to stretch out, snubber body 2 is shunk with its inwardly compression as need, closes a snubber and possesses can adapt to after such adjustment function and have difference and close various an of pressure.
The utility model closes a snubber and generally is installed on the position that hinge is installed on the cabinet door; when the cabinet door is closed; at first can contact headgear 3 parts of closing a snubber; headgear 3 is under pressure and impels its inner screw rod 9 to rotate relative to headgear 3; because screw rod 9 ends and slide bar 10 end frictional fit; and slide bar 10 rear ends are stretched in the sliding sleeve 8; the rotation of slide bar 10 is subjected to the resistance oil restriction in the sliding sleeve 8 equally; therefore the rotation of screw rod 9 is very slow; and then make the retraction of body headgear 3 equally also very slow, no matter and to close a speed of much its retractions of dynamics constant substantially.
