Description

Speed regulating hinge

Technical field

The utility model relates to a kind of Speed regulating hinge, mainly is used on the labeled door.

Background technology

Labeled door commonly used at present generally only is equipped with spring hinge, put in place the pass rapidly in order to ensure labeled door, the spring that spring hinge adopted mostly is the bigger rectangle spring of torsion, and there is following defective in this spring hinge: at closing time, hinge is moved rapidly by spring action, because the speed of closing the door is too fast, doorframe can be subjected to very big impact, also can produce very big noise, and because the speed of closing the door is too fast, door leaf also can occur and beat phenomenon on the person, life safety is on the hazard.

Summary of the invention

The purpose of this utility model provides and a kind ofly can prevent that doorframe is hit, and can prevent that again personal safety is subjected to the Speed regulating hinge of closing the door and threatening.

The technical scheme that realizes above-mentioned purpose is: a kind of Speed regulating hinge, comprise blade, last sleeve pipe, lower blade and setting of casing, also comprise central axis, lining, spring, spring base and a plurality of friction plate that stacks, the top of central axis is connected with last sleeve pipe by unilateral bearing, the middle part of central axis is connected with lining by bearing, and pad is arranged in central axis underrun screw, lining is fixedlyed connected with setting of casing, friction plate all is sleeved on the central axis bottom, and be full of damping glue between the friction plate, the friction plate on top is against on the lining, the friction plate of bottom is bearing on the spring, the lower end of spring is bearing on the spring base, and spring base and setting of casing inwall lower end are fixed.

After adopting technique scheme, because the top of central axis is connected with last sleeve pipe by unilateral bearing, when opening the door, central axis is in free state, have only last sleeve pipe and blade to rotate with door leaf, last sleeve pipe can not drive central axis and rotate together, and it is laborsaving convenient again to open the door.At closing time, blade rotates with door leaf, last sleeve pipe rotates with blade, last sleeve pipe drives central axis by unilateral bearing and rotates together, the rotation of central axis drives friction plate again and rotates, and be full of damping glue between the friction plate, form buffer gear, and because the damping action of buffer gear slows down the rotating speed of central axis, and and then slow down and go up sleeve pipe, the rotating speed of blade, thereby the rotating speed of door leaf is slowed down, reduce the speed of closing the door, avoid doorframe to be subjected to big impact and damage, also be unlikely to close too fast hitting on the person, prevent that personal safety is on the hazard because of door leaf.Because the friction plate of bottom is bearing on the spring, and spring is bearing on the spring base, by the pretightning force of regulating spring, can regulate the gap between the friction plate, and then regulates cushion effect, thereby the user can be provided with the speed of closing the door as required.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As Fig. 1, shown in 2, a kind of Speed regulating hinge, comprise blade 18, last sleeve pipe 1, lower blade 17 and setting of casing 9, also comprise central axis 4, lining 6, spring 13, spring base 14 and a plurality of friction plate that stacks 8, the top of central axis 4 is connected with last sleeve pipe 4 by unilateral bearing 3, the middle part of central axis 4 is connected with lining 6 by bearing 5, and be fixed with pad 11 at central axis 4 underrun screws 12, lining 6 is fixedlyed connected with setting of casing 9, friction plate 8 all is sleeved on central axis 4 bottoms, and be full of damping glue between the friction plate 8, the friction plate 8 on top is against on the lining 6, the friction plate 8 of bottom is bearing on the spring 13, and the lower end of spring 13 is bearing on the spring base 14, and spring base 14 is fixed with setting of casing 9 inwall lower ends.Spring base 14 can adopt with being connected of setting of casing 9 inwalls and be threaded, and is convenient to the displacement of regulating spring seat 14 in setting of casing 9, thus the pretightning force of adjustable springs 13.Can prevent that by screw 12 and pad 11 are set central axis 4 from extracting out from the hole of friction plate 8, can prevent that also friction plate 8 from falling from central axis 4, be convenient to install.

As shown in Figure 1, the lower end of central axis 4 is set with axle sleeve 10, and the lower end of axle sleeve 10 is against on the pad 11.By adopting the axle sleeve 10 of differing heights, can select the friction plate 8 of varying number for use, thereby regulate the resistance of buffer gear.

As shown in Figure 1, lasso 15 is installed in the lower end of setting of casing 9 and pipe cover 16, and this lasso 15 is fixedlyed connected with setting of casing 9 inwall lower ends, and pipe covers 16 and lasso 15 snappings.Adopt this structure can prevent that dust etc. from entering setting of casing 9, avoid the parts in the setting of casing 9 to get rusty.And make the good looking appearance of hinge.

As shown in Figure 1, lasso 15 is installed in the upper end of last sleeve pipe 1 and pipe cover 16, and this lasso 15 is fixedlyed connected with last sleeve pipe 1 inwall upper end, manages to cover 16 and lasso 15 snappings.Adopt this structure can prevent that dust etc. from entering sleeve pipe 1, prevent that the part in the sleeve pipe 1 from getting rusty.And make the good looking appearance of hinge.

Since pipe cover 16 and lasso 15 be connected to snapping, thereby mount and dismount very conveniently, be convenient to the maintenance of Speed regulating hinge.

As shown in Figure 1, be provided with sealing ring 7 between last sleeve pipe 1 and the setting of casing 9.Adopt sealing ring 7 can prevent that dust, steam from entering upper and lower sleeve pipe 1,9 between the upper and lower sleeve pipe 1,9, prevent that the part in the upper and lower sleeve pipe 1,9 from getting rusty, damaging, thereby prolong the application life of hinge.

As shown in Figure 3, the utility model is installed in the top of door leaf and doorframe in use, is used with the spring hinge that is installed in door leaf and doorframe top, constitutes a pair.

Operating principle of the present utility model is as follows: when opening the door, because the effect of unilateral bearing 3, central axis 4 is in free state, has only last sleeve pipe 1 and blade 18 to rotate with door leaf, and last sleeve pipe 1 can not drive central axis 4 and rotate together, opens the door laborsavingly to make things convenient for again.At closing time, blade 18 rotates with door leaf, last sleeve pipe 1 rotates with blade 18, last sleeve pipe 1 drives central axis 4 by unilateral bearing 3 and rotates together, the rotation of central axis 4 drives friction plate 8 again and rotates, and be full of damping glue between the friction plate 8, form the buffer gear that hinders central axis 4 rotations, and because the damping action of buffer gear slows down the rotating speed of central axis 4, and and then slow down and go up sleeve pipe 1, the rotating speed of blade 18, thereby the rotating speed of door leaf is slowed down, reduce the speed of closing the door, avoid doorframe to be subjected to big impact and damage, also be unlikely to close too fast hitting on the person, prevent that personal safety is on the hazard because of door leaf.Because the friction plate 8 of bottom is bearing on the spring 13, and spring 13 is bearing on the spring base 14, by the displacement of regulating spring seat 14, the pretightning force of regulating spring 13, can regulate the gap between the friction plate 8, and then regulate cushion effect, thereby the speed that can close the door according to the needs setting of user.
