Abstract
The invention discloses an automatic lifting threshold device. The automatic lifting threshold device comprises a concave threshold base arranged below the ground plane, and an elastic step which is arranged on the base and can expand and contract vertically along the ground plane, wherein the elastic step comprises a panel movably embedded into the threshold base and an elastic component arranged below the panel; a framework is embedded to the ground, and the framework and a whole equipment room framework are mutually connected into a whole; an automatic lifting threshold is fixed on the embedded framework; the lifting of the threshold is mainly realized through elasticity of three groups of springs, namely when equipment passes through the threshold, the threshold is pressed to the height approximate to that of the ground according to the weight of the equipment, the threshold restore to a lifted state through the elastic force of the threshold after the equipment leaves the threshold, at the moment, the threshold and an inlet and outlet door are connected into a whole; if a sealing strip is arranged beside the door, the threshold and the inlet and outlet door can form a closed space, and meanwhile the automatic lifting threshold device can have the effects of dust prevention and sound insulation.
Description
Technical field
The present invention relates to a kind of threshold, apply to scroll wheel device particularly to one kind and smoothly pass through threshold and realize setting
There is the automatic-lifting type threshold device that the occasions such as the high confined space of inlet/outlet equipment room obtain.
Background technology
Existing lift doorsill device mostly reversely to realize threshold using reversal designs such as telescopic switch doors at present
Elevating function, major way is to ensure the smooth of ground first or slot on the ground, stretches in the upper setting of switch gate and fills
Put, close and stretch out a threshold behind the door, a confined space is formed with this and equipment of realizing smoothly passes through inlet/outlet.But this structure
Shortcoming one is to be not very convenient to use, and has strict demand to the retracted position of retractable door it is impossible to malfunction during switch gate；Two are
High leakproofness to be realized is it is necessary to realize with ground auxiliary device cooperation.
Content of the invention
In view of this, it is an object of the invention to provide a kind of automatic-lifting type threshold device, equipment can be made steadily to lead to
Cross threshold, safe and reliable, durable in use, ensure that equipment room has the features such as high leakproofness, dust-proof, sound insulation and lucifuge simultaneously
Require；Do not affect the design of the External Systems such as inlet/outlet, simple and practical, strong applicability.
The automatic-lifting type threshold device of the present invention, including the spill threshold pedestal being arranged under ground level and be arranged at base
The elastic step that can stretch up and down along ground level on seat；
Further, described elasticity step includes the panel that activity is embedded in threshold pedestal and the elasticity being arranged under panel
Part；
Further, described elastomeric element includes spring and the upper bush being sheathed on both ends of the spring respectively and lower sleeve, described
Upper bush bore is with more than or less than the setting of lower sleeve bore；
Further, described threshold pedestal is included trough-shaped base and is fixedly installed on being fixedly connected with lower sleeve on base
Erection support；
Further, described erection support is π shape part, the fixing trough-shaped base rising wood of wing plate overlap joint of described π shape part；
Further, described trough-shaped base is provided with bearing pin spacing hole；
Further, described trough-shaped base is fixedly installed on doorframe skeleton；
Further, described threshold and its coordinate and be additionally provided with sealing strip between the door of closing.
Beneficial effects of the present invention: the automatic-lifting type threshold device of the present invention, by the pre-buried skeleton in ground, and this skeleton and
Whole equipment room skeleton is connected as a single entity, and fixes automatic lifting threshold on pre-buried skeleton, and three groups of bullets are mainly passed through in the lifting of threshold
The contractility of spring realizing it may be assumed that equipment is when threshold passes through, is depressed into about ground level according to weight of equipment threshold, equipment from
After enabling sill, threshold leans on its own resilient, and threshold recovers increasing state, and now threshold and inlet/outlet are connected as a single entity, if setting in Men Bian
It is equipped with sealing strip, then threshold and inlet/outlet can form a confined space, dust-proof, sound insulation and other effects can also be played simultaneously.
Brief description
The invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the cross-sectional view in the case of elastic step reduces for the automatic-lifting type threshold device of the present invention；
Fig. 2 is the top view of the present invention；
Fig. 3 is the a-a structural representation under the elastic step increasing state of Fig. 2；
Fig. 4 is the c-c structural representation of Fig. 3.
Specific embodiment
Fig. 1 is the cross-sectional view in the case of elastic step reduces for the automatic-lifting type threshold device of the present invention；
Fig. 2 is the top view of the present invention；Fig. 3 is the a-a structural representation under the elastic step increasing state of Fig. 2；Fig. 4 is
The c-c structural representation of Fig. 3.As shown in the figure: the automatic-lifting type threshold device of the present embodiment, including being arranged under ground level 1
Spill threshold pedestal 2 and be arranged on pedestal 2 can be along the flexible elastic step 3 about 1 of ground level；Need for some equipment
Smoothly pass threshold it is impossible to there is the process of situation about jolting, when opening behind the door, can be light by equipment self-weight or artificial external force
Slowly being depressed into threshold step 3 of pine about flushes height with ground, allows equipment smoothly pass through threshold.
In the present embodiment, described elasticity step 3 includes the movable panel being embedded in threshold pedestal 2 and is arranged under panel
Elastomeric element 4；Panel under the driving of elastomeric element, along threshold pedestal 2 groove, longitudinally stretch by (vertical threshold pedestal 2 direction)
Contracting.
In the present embodiment, described elastomeric element 4 includes spring 41 and upper bush 42 He being sheathed on spring 41 two ends respectively
Lower sleeve 43, described upper bush 42 bore is with more than or less than the setting of lower sleeve 43 bore；Upper bush 42 and lower sleeve 43 can be
Under pressure moving axially relative to coincidence status.
In the present embodiment, described threshold pedestal 2 includes trough-shaped base 5 and is fixedly installed on solid with lower sleeve 43 on base
The fixed erection support 6 connecting；Erection support 6 is used for fixing lower sleeve 43 and being fixed elasticity step 3 by supporting on vertical pressure.
In the present embodiment, described erection support 6 is π shape part, fixing trough-shaped base 5 upper limb of wing plate overlap joint of described π shape part
Portion；Structure is simply it is easy to installing and operate, the wing plate 61 of π shape part being fixed on trough-shaped base 5 by screw.
