Abstract
Air spring door, including the guard gate, the upper end of guard gate is articulated with the support, and the guard gate forms sealed cooperation with the support, and the key is: add the air spring in the inboard of guard gate, the one end and the support of air spring are articulated, and the other end of air spring is articulated with the guard gate, and the guard gate is with the help of extension or shrink and the support separation or the sealed cooperation of formation of air spring. Effectively solved the sealed not tight problem of guard gate, obtained very good application under hazardous gas's environment, convenient operation has reduced workman's intensity of labour moreover, need not use the switch that just can realize the guard gate too energetically.
Description
Technical field
The utility model belongs to protective door technical field, relates to air spring door.
Background technology
Dry run due to many special fibres need add the gas of toxic contaminants environment, therefore very high requirement is sealed with to dryer protective door, and require in actual production, want simply easy to operate, usually protective door used is generally is mostly guide tracked or electric sliding, but sealing effectiveness is not ideal.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises air spring door, solves the difficult problem that existing protective door sealing effectiveness is undesirable well, and convenient operation.
The concrete technical scheme that the utility model is taked is: air spring door, comprise protective door, upper end and the support of protective door are hinged, protective door and support are formed and are sealed and matched, key is: set up air spring in the inner side of protective door, one end and the support of air spring are hinged, and the other end and the protective door of air spring are hinged, protective door by air spring elongation or shrink to be separated with support or to be formed and be sealed and matched.
The quantity of described air spring is two, and two left and right sides of air spring in protective door are symmetrical arranged.
Described protective door is provided with bearing, and one end of bearing is fixedly connected with support, and the other end and the air spring of bearing are hinged.
The other end of described air spring by bearing pin and protective door hinged.
Be provided with sealing strip between described protective door and support, sealing strip is sleeved on protective door.
The coefficient of elasticity of described air spring is 1.3.
The beneficial effects of the utility model are: efficiently solve the problem that protective door is poorly sealed, extraordinary utilization is obtained under the environment of toxic and harmful, and easy to operate, reduce the labour intensity of workman, do not need the switch with protective door just can be realized too energetically.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A direction view of Fig. 1.
In accompanying drawing, 1 represents air spring, and 2 represent bearing, and 3 represent protective door, and 4 represent support, and 5 represent bearing pin, and 6 represent sealing strip.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 1 and Figure 2, air spring door, comprises protective door 3, and upper end and the support 4 of protective door 3 are hinged, protective door 3 and support 4 are formed and are sealed and matched, set up air spring 1 in the inner side of protective door 3, the coefficient of elasticity of air spring 1 is 1.3, and one end and the support 4 of air spring 1 are hinged, the other end and the protective door 3 of air spring 1 are hinged, protective door 3 by air spring 1 elongation or shrink to be separated with support 4 or to be formed and be sealed and matched.Wherein, protective door 3 is provided with bearing 2, one end of bearing 2 is fixedly connected with support 4, and the other end and the air spring 1 of bearing 2 are hinged, and the other end of air spring 1 is hinged by bearing pin 5 and protective door 3.
As to further improvement of the utility model, the quantity of air spring 1 is two, two left and right sides of air spring 1 in protective door 3 are symmetrical arranged, make protective door 3 left and right sides pressure like this and to lift power all consistent, sealing effectiveness is all consistent, also more solid and reliable when protective door 3 is supported.
As to further improvement of the utility model, be provided with sealing strip 6 between protective door 3 and support 4, sealing strip 6 is sleeved on protective door 3, can improve sealing effectiveness further.
The utility model is in the specific implementation: at air spring 1 the most in short-term, protective door 3 left and right sides is unanimously stressed, its deflection is consistent to be after compaction arranged on sealing strip 6 on protective door 3, and protective door 3 and support 4 are tightly fitted air tight, serve sealing function well; Air spring 1 the longest position time, protective door 3 left and right sides is unanimously stressed, and it is firm that protective door 3 supports.The utilization of air spring 1 also significantly reduces the labour intensity of workman, does not need the switch with just realizing protective door 3 too energetically.
