Description

Door stopper

The utility model relates to the suspension arrangement that door and window in a kind of building field or wing are used, particularly relating to a kind of being provided with makes door can close structure automatically, two flat spring Yin Kaimen action is by after the torsional deflection in the lid up and down, produce one and desire the twisting force of reinstatement, and make the structure improved Door stopper that can close automatically.

Modern society is along with people's living standard improves constantly, almost every household all is equipped with cold air, and in the cold air room, close the door if forget, then cold air runs off easily, old-fashioned door in the past is after it opens the door, because of no Door stopper control action, door can't be playbacked voluntarily, the user must whip door is with again, but the relatively poor people of some custom forgets this action often, interior temperature can't be descended, puzzlement other people, and the modern more and more payes attention to the right of privacy always wish to have a to one's name not disturbed space, but in daily life, in company and colleague's coexistence, be in and just live in the household, real one's own place is seldom arranged, but can reach this purpose by shutting door, closing in the room to the doorstep, people can have the more right of privacy, make oneself to loosen being Myself of mood and want the thing done, therefore, a kind of make the door Door stopper of closing automatically promptly in response to and give birth to.

Traditional Door stopper, promptly respectively install a spring on door and door-plate, two springs are unified cylinder indirectly, when door is drawn back, spring on the Door stopper promptly is elongated, when hand was decontroled, the strength by the reinstatement of spring desire playbacked door rapidly, therefore make too much noise with door-plate, other people are got a fright, and door and door-plate be because of clashing into often, also damage easily, in view of this, now promptly occurred a kind of Door stopper of closing the door and moving on the market, but its structure is complicated, during production costs with the control of oil pressure frame mode, cost is increased, and after getting loose for a long time, can't adjust once again, more uneconomical.

Because the drawback of above-mentioned traditional product, the design people based on for many years to Door stopper enrich practical experience and professional knowledge, through constantly studying, design, and after studying sample repeatedly and improving, create the utility model finally.

Main purpose of the present utility model is, overcome the deficiencies in the prior art, and provide a kind of structure improved Door stopper, its design is had make the structure that can close automatically, the back door of opening the door can be shut automatically, by being buckled in two flat springs in the up and down lid and Coupling Shaft by torsional deflection, making spring have a torsion of desiring reinstatement to make can shut gently automatically, avoid producing the huge sound and influence other people, and it also can do the adjusting of spring torsion earlier with adjusting rod, make spring in advance by torsional deflection, can increase the speed that the torsion adjustment of spring is closed the door.

The purpose of this utility model is realized by following technical scheme.A kind of structure improved Door stopper, comprise the structure of automatically door being closed, it is characterized in that it mainly is made up of a main body, a positioning rod and an adjusting rod member, wherein, this main body, comprise upper cover body, lower cover, Coupling Shaft, on reverse body and under reverse body; This upper cover body is one to be the U type body of hollow, is provided with a platform at side; This Coupling Shaft, its central authorities are penetrated with a centre bore, offer some screws on the peripheral anchor ring in regular turn; This lower cover, its profile is identical with upper cover body; On reverse body, an end is buckled in the inside of upper cover body, an end is buckled on the Coupling Shaft, forms a first half main body; Under reverse body, an end is buckled in the inside of lower cover, the other end is buckled on the axial plane of the Coupling Shaft other end, forms a Lower Half main body; One joint element is bonded into a complete main body with first half main body and Lower Half main body, and the other platform of main body is attached on the door-plate and engages with door-plate; This backstay, the one end is provided with screw thread, and interlocking is in the screw of the peripheral anchor ring of Coupling Shaft, and the other end respectively is equiped with a pulley that roll in the original place on door in both sides; The close the door adjusting rod of speed of this adjustment, an end is provided with screw thread, and interlocking is in the screw of the peripheral anchor ring of Coupling Shaft.

The purpose of this utility model can also further realize by following technical measures.Aforesaid Door stopper, wherein said upper and lower cover body, its center, upper cover body top is penetrated with a screw, and this screw side offers the circular groove that reverses the body buckle on; Lower cover is provided with the inserted link that a center is provided with screw thread in the central authorities of inner bottom, and bottom one side is provided with the circular groove that reverses the body buckle.Aforesaid Door stopper respectively is provided with a flange on its two ends axial plane of wherein said Coupling Shaft, and this flange side respectively offers a upper and lower perforation of reversing the body buckle at relative angle place, axial plane two ends.Aforesaid Door stopper reverses body on wherein said, reverses body down and can be a torque spring.Aforesaid Door stopper, wherein said joint element can be a screw.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, a kind of structure improved Door stopper of the utility model, it is designed primarily to the structure that door can be closed automatically, the feasible back door of opening the door can automatically be shut, it mainly is made up of members such as a main body, Coupling Shaft and a positioning rod and adjusting rods, this main body includes lid up and down, a spring is respectively installed in its inside, be provided with a Coupling Shaft up and down between lid, spring one end is buckled in up and down in the lid, the other end is buckled in the Coupling Shaft both sides between lid up and down, and utilize a screw to incite somebody to action up and down lid becomes a main body with the Coupling Shaft interlocking; These backstay one end both sides respectively are provided with a pulley, and an end then is screwed onto on the Coupling Shaft; This structure is locked on door-plate, an end that makes backstay be provided with pulley fits tightly with door, when opening the door, backstay is provided with end original place on door of pulley and rolls, and the length that the drive backstay is done with backstay along the direction of opening the door is the circular motion of radius, makes backstay rotate Coupling Shaft, and be buckled in spring in the Coupling Shaft promptly by torsional deflection, the twisting force of borrowing spring that one desire reinstatement is arranged can make the door of opening shut automatically, and have the effect of closing the door automatically; It is by being buckled in two flat springs in the up and down lid and Coupling Shaft by torsional deflection, make spring have one to desire the torsion of reinstatement and make and can shut automatically gently, avoid producing the very big sound and influenced other people, and it also can do the adjusting of spring torsion earlier with adjusting rod, make that spring can be in advance by torsional deflection, thus the speed that can close the door with the torsion adjustment that increases spring.

In sum, Door stopper structure of the present utility model, be provided with the structure that door can be closed automatically, two flat spring Yin Kaimen action is produced a twisting force of desiring reinstatement after the torsional deflection in the lid up and down, can close automatically and make, it is for present Door stopper, real is a kind of optimal door automatic closing structure, no matter it structurally or all have on the function significantly and to improve, it really is a progressive design, the utility model is that initiative did not appear and really belonged in like product again, is the new design of a novelty, practicality in fact.
