Abstract
The utility model discloses an adjustable automatic door closing mechanism which comprises a base; a fixed block is arranged on the base, an elastic part is arranged by penetrating through the fixed block, and an adjusting block is arranged at the end part of the elastic part. The adjusting block is arranged on the elastic part and can realize the regulation of pre-tightening force of closing a door, and the design has the advantages of simple structure, low cost and durability. A positioning slot on the adjusting block is matched with an elbow at the end part of a spring steel wire for positioning the spring steel wire, thereby effectively simplifying the mechanism, simplifying the process and realizing easy implementation.
Description
Technical field
The utility model relates to a kind of door engine structure of regulating.
Background technology
At present, part wine cabinet on the market, showcase or building door body have had the door engine structure, but the used mechanism of closing the door adopts torsion spring more, the torsion spring restoring force is unadjustable, because door body switch number of times is more, along with continuous fatigue deformation, torsion spring will be lost the ability of closing the door automatically gradually, very manually closing behind the door also may appear in the person, because of the situation that the torsion spring distortion flicks door, brings very big inconvenience for people's daily life, work.
The utility model content
The purpose of this utility model provides a kind of door engine structure of regulating, and it is simple in structure, the pretightning force of closing the door is adjustable, durable in use.
For achieving the above object, the technical solution of the utility model is: a kind of door engine structure of regulating, comprise pedestal, and pedestal is provided with fixed block, passes fixed block and is provided with elastic component, and described elastic component end is provided with the adjustment piece.
Described elastic component is a spring steel wire, its outer stationary pipes that is arranged with, and the stationary pipes upper end tightens and is located at fixed block inside with spring steel wire tight fit, lower end, and the spring steel wire lower end is bent with elbow.
Described adjustment piece is inner porose stepped, and the end has the locating slot that the elbow with spring steel wire adapts; Adjust packaged being located on the pedestal and with stationary pipes and contact, adjust piece and cooperate with fixed block and pedestal activity, the corresponding piece of adjusting is provided with lock-screw on the fixed block.
Described stationary pipes is provided with block, is provided with packing ring between block and the fixed block.
The utility model is provided with the adjustment piece on elastic component, can realize the adjusting to the pretightning force of closing the door, and this project organization is simple, with low cost, durable in use.Spring steel wire is arranged with stationary pipes outward, locatees simple and reliable, and aesthetic in appearance generous.The locating slot of adjusting on the piece cooperates with the elbow of spring steel wire end, and the retainer spring steel wire effectively simplifies the internal structure of an organization, and activities is simple, is easy to realize.Be provided with packing ring between block and the fixed block, make mechanism wear-resisting durable, not fragile.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
The door engine regulated structure as shown in Figure 1 and Figure 2, it comprises pedestal 4, is provided with fixed block 5 on pedestal 4, passes fixed block 5 and is provided with elastic component 2, is provided with in the end of elastic component 2 to adjust piece 1, by adjusting piece 1 fixing, adjustment elastic component 2.
As shown in Figure 1 and Figure 2, elastic component 2 is spring steel wires, also can be the elastic component that torsion spring etc. has distortion and recoverability.Be arranged with stationary pipes 3 outside the elastic component 2, utilize extrusion equipment that the upper end extruding of stationary pipes 3 is tightened, make the port and elastic component 2 tight fits that tighten, to play the fixedly effect of elastic component 2; The lower end of elastic component 2 is bent with elbow 21.Adjust piece 1 and be inner porose stepped, and the bottom has the locating slot 11 that the elbow 21 with elastic component 2 adapts, elbow 21 is stuck in the locating slot 11, guarantees that elastic component 2 lower ends can not rotate with the rotation of upper end.Adjusting piece 1 activity is installed in upper limb 41 middle parts of pedestal 4 and contacts crimping with stationary pipes 3, adjusting piece 1 cooperates with fixed block 5 activities of top, fixed block 5 is fixed on upper limb 41 middle parts of pedestal 4 by bolt or pin 6 from the top of adjusting piece 1, while is provided with on fixed block 5 and is used for fixing the lock-screw 9 of adjusting piece 1, backs out lock-screw 9 and be fixed after the position of adjusting piece 1 is determined.On stationary pipes 3, be provided with block 7, be provided with packing ring 8 between block 7 and the fixed block 5,, increase the service life to reduce the wearing and tearing of stationary pipes 3, block 7 and fixed block 5.
Assembling process of the present utility model is: the upper end of elastic component 2 penetrates and elbow 21 is sticked into the locating slot 11 of adjusting piece 1 from adjusting piece 1 below, insert from fixed block 5 belows adjusting piece 1, the stationary pipes 3 that has block 7 is inserted above fixed block 5, stationary pipes 3 is crimped on to be adjusted on the piece 1, the upper end of elastic component 2 passes from the upper end of stationary pipes 3, with extrusion equipment fixedly elastic component 2 of reducing is pushed in stationary pipes 3 upper ends, make its play, rotation up and down.The mechanism that combinations thereof is good is fixed on the upper limb 41 of pedestal 4 with two bolts or pin 6, with screw 10 lower edge 42 of pedestal 4 is fixed on the installation site again.Stationary pipes 3 is fixedlyed connected by block 7 with the door body.Block 7 and stationary pipes 3 riveted joints or welding.After each parts of mechanism install, adjust piece 1 to suitable pretightning force, with the lock-screw 9 fixing pieces 1 of adjusting with the spanner rotation.
When the door body was opened, block 7 rotated simultaneously with stationary pipes 3, and rotated by the stationary pipes 3 upper ends position elastic component 2 that links to each other with elastic component 2, because elastic component 2 bottom elbows 21 are stuck in the locating slot 11 of adjusting piece 1, so elastic component 2 generation elastic distortions are out of shape; When no longer including masterpiece and be used for body, the process of elastic component 2 reinstatements produces moment of torsion, and moment of torsion is delivered to by stationary pipes 3 and block 7 body is closed.When using a period of time, permanent deformation can take place in elastic component 2, and when a feasible body reached certain angle, the moment of torsion that elastic component 2 is produced was not enough so that the door body is closed, and only needed to regulate pretightning force by adjusting adjustment piece 1 this moment and got final product.Control method is: unclamp lock-screw 9, adjusting piece 1 with the spanner rotation increases pretightning force to correct position, tightens lock-screw 9 again and gets final product.
Be not limited to above-mentioned embodiment: stationary pipes 3 of the present utility model also can connect with elastic component 2 fixing by pin or key.
