Thus, the production and the assembly of the door closer are simpler and easier, and the using process has high sealing property and good buffer effect.
Description
[technical field]
The utility model is about a kind of complementary shutoff device, is meant a kind of door closer structure that can close the door automatically especially.
[background technology]
See also shown in Figure 5, general door closer be comprise a metal material make outside pipe (50), this outer tube (50) has two ends, one is first end (56), another is second end (58).A part (52) combines in the riveted mode with first end (56), and a stopper (54) also combines in the riveted mode with second end (58).One exhaust passage (62) takes shape in a part (52), is connected with outer tube (50) inside, and an adjustment screw (60) is locked in the exhaust passage (62) establishes Position Control capacity or exhaust velocity by lock.Surperficial winding one spring of one pull bar (68) (66), pull bar (68) is placed in the outer tube (50) with spring (66), and one of pull bar (68) end is provided with a piston (64) and offsets with spring (66).The other end of this pull bar (68) passes stopper (54) and is exposed to outside the outer tube (50).
The user opens door simultaneously, the strength that the piston (64) of this pull bar (68) can open the door because of the user is away from a part (52), meeting interlock spring this moment (66) is to produce a restoring force, strength disappears when opening the door, the restoring force of spring (66) just can make pull bar (68) return back to initial position, and door is then shut automatically.
More than prior art easily produce following shortcoming:
One, because a part (52) combines in the riveted mode with first end (56), and stopper (54) also combines in the riveted mode with second end (58), not only processing time consuming, and process trouble.
Two, owing to the combination of pull bar (68) with spring (66) places earlier in the outer tube (50), and pull bar (68) one ends pass the riveted processing of just carrying out outer tube (50) and stopper (54) behind the stopper (54), so be vulnerable to the interference of pull bar (68) in the riveted process of outer tube (50) and stopper (54), so need the special tool of utilization, and then cause the assembling difficulty.
Three, combine by the riveted mode with first end (56) owing to a part (52), thus the easily not driving fit of riveted place, so can produce the situation of gas leakage and relatively poor buffering effect.
[summary of the invention]
Because the disclosed door closer of prior art can produce the assembling difficulty of processing time consuming and process trouble, inter-module, the easy situation of buffering effect difference in gas leakage and the use of inter-module when using, so main purpose of the present utility model is to provide a kind of door closer structure of innovation, to solve the shortcoming of prior art.
The utility model is to realize like this, a kind of door closer, be that an operating assembly is assembled in a pipe fitting inside, and a stopper group is located at this pipe fitting one end, and this pipe fitting one end is formed with a head, and the body of this head and pipe fitting is one-body molded, this pipe fitting other end is that an openend and internal face form one first combined structure, this stopper one side has one second combined structure, and stopper is mounted on openend, and first combined structure and second combined structure are interosculated.Solve the inter-module assembling difficulty of door closer that prior art discloses in view of the above effectively, the easy shortcoming of buffering effect difference in gas leakage and the use of inter-module when using.
Door closer provided by the utility model, it has integrated assembly, so not only the assembling of inter-module is easy for this door closer, and the adaptation of inter-module is good and use in buffering effect good.

[specific embodiment]
See also Fig. 1～shown in Figure 3, the door closer that the utility model will disclose is made up of a pipe fitting (10), an operating assembly (20) and a stopper (30).
This pipe fitting (10) is to go out a body (11) by the plastic material ejection formation, and these body (11) one ends have a head (12), and the other end forms an openend (14).This head (12) more includes an exhaust passage (18) and is connected with pipe fitting (10) inside, and one adjusts screw (19) is locked on exhaust passage (18) and mat lock and establishes the position and control capacity.The end internal face of this openend (14) forms one first combined structure (16), and this first combined structure (16) is an overhead kick columnar structure.
This operating assembly (20) is made up of a pull bar (22) and a spring (24).These pull bar (22) one ends have a piston (26), and spring (24) is set around pull bar (22) periphery, and spring (24) one ends are replaced mutually with piston (26).
This stopper (30) middle position forms a perforation (32), and stopper (30) one sides form one second combined structure (34), and this second combined structure (34) is for colluding columnar structure.
This operating assembly (20) is to place in the pipe fitting (10), and the relative head (12) of piston (26); Stopper (30) group is located at openend (14), and first combined structure (16) interosculates with second combined structure (34), and these pull bar (22) one ends pass perforation (32) and are exposed to outside the pipe fitting (10).
See also shown in Figure 4ly, when the pull bar (22) of the utility model is subjected to an external force F, the active force that for example opens the door makes pull bar (22) displacement, and spring (24) is subjected to piston (26) compacting to produce a restoring force; When this external force F disappearance, then the restoring force of spring (24) makes pull bar (22) return back to initial position, and reaches the effect of closing the door automatically.
According to the explanation of above embodiment, the utlity model has following advantage:
One, the body (11) of this pipe fitting (10) is one-body molded by the plastic material ejaculation with head (12), and is simple for production quick.
Two, return back in the process of initial position at this pull bar (22), because pipe fitting (10) and head (12) are to be penetrated one-body moldedly by plastic material, so head (12) can not produce the situation of gas leakage, in other words sealing property is good and resiliency is good.
