End is fixed on door closer shell, so that torsion bar torsion certain angle puts aside energy.Compared to the prior art, torsion bar structure
Simply, easy for installation, and high reliablity, ambient adaptability is good, is suitable for use on fire resistant doorsets, in various high temperature, cold conditions
Under can reliably working, therefore, when using torsion bar, the sealing performance of door closer requires decline, thus reduce production, manufacture at
This, manufacturer does not have in cost great amount of cost on pursuing sealing performance.The elastic property of torsion bar unit volume savings is than existing
Some cylindrical springs are big, thus, for the door of same specification weight, the quality of torsion bar is smaller than the quality of spring, also just convenient
In transport, installation.It also has the advantage that because torsion bar can generally generate a permanent torsional deflection when manufacturing, so that torsion bar
With certain prestressing force, meanwhile, because the direction and torsion bar to the torsion of torsion bar pre-add are mounted on and reverse on door closer shell
Direction is identical, it is therefore an objective to reduce actual stress when work, extend the service life, while but also door close more will be tight, protection effect
Fruit is more preferable.Because the windup-degree of torsion bar is limited, and the angle of torsion bar torsion is generally acute angle, in order to avoid opening the door, closing
Men Shi, torsion bar windup-degree is excessive, and being realized by transmission device becomes the small torsion angle of torsion bar for the big rotational angle of transmission shaft
Degree.In the utility model, transmission shaft is continued to use traditional design and is arranged on the side wall of door closer ontology, i.e., the utility model is still

Embodiment 8
On the basis of embodiment 5 or 8, it is provided with regulating tank 103, lower regulating tank 104 on door closer shell 1, two
Oil filler point plunger 605 or air volume regulating valve 603 are stretched out from corresponding upper regulating tank 103, lower regulating tank 104 respectively.
In the present embodiment, for the ease of adjusting the cushion performance of upper and lower compression buffer, it is provided on door closer shell 1
Upper regulating tank 103, lower regulating tank 104 are just adjusted at this point, being not required to disassembly door closer.
Embodiment 9
On the basis of the above embodiments, the left side wall of door closer shell 1, be provided with installation foot 101 on right side wall.
Because 2 stress of torsion bar is reversed, the both ends for being fixed on door closer shell 1 using existing screw at this time are improper, because
Bad for stress condition, door closer ontology 1 can be directly detached from from door, and the upper of door closer ontology 1 is arranged in installation foot 101
On side wall, lower wall, at this point, due to increasing the arm of force, the screw squeezed on installation foot 101 can be well by door closer ontology
1 is fixed on door.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
