Abstract
The utility model discloses a kind of automatic-lifting type threshold device, comprise the spill threshold pedestal that is arranged under ground line and be arranged at the elasticity step that pedestal can stretch up and down along ground line; Described elasticity step comprises activity and is embedded at the panel in threshold pedestal and the elastomeric element under being arranged at panel; By the pre-buried skeleton in ground, and this skeleton and whole equipment room skeleton are connected as a single entity, pre-buried skeleton is fixed automatic lifting threshold, the lifting of threshold realizes mainly through the contractility of three groups of springs, that is: when equipment passes through from threshold, according to weight of equipment, threshold is depressed into about ground level, after equipment leaves threshold, threshold is by its own resilient, threshold recovers increasing state, and now threshold and inlet/outlet are connected as a single entity, if be provided with weather strip on door limit, then threshold and inlet/outlet can form a confined space, also can play the effects such as dust-proof, sound insulation simultaneously.
Description
Technical field
The utility model relates to a kind of threshold, and particularly a kind of scroll wheel device that applies to is provided with the automatic-lifting type threshold device that the occasions such as the high confined space of inlet/outlet equipment room obtain stably by threshold and realization.
Background technology
Current existing ascending/decending doorsill device mostly adopts the reverse engineer such as telescopic switch door oppositely to realize the elevating function of threshold, major way is first ensure the smooth of ground or slot on the ground, switch gate arranges stretching device, close and stretch out a threshold behind the door, form a confined space with this and realize equipment and pass through inlet/outlet stably.But this structural disadvantages one is not very convenient to use, and has strict demand during switch gate to the retracted position of retractable door, can not make mistakes; Two is to realize high seal, must coordinate realize with ground auxiliary device.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of automatic-lifting type threshold device, and equipment can be made to smoothly pass threshold, safe and reliable, durable in use, ensure that equipment room has high seal, dust-proof, the Functional Requirement such as sound insulation and lucifuge simultaneously; Do not affect the design of the External Systems such as inlet/outlet, simple and practical, applicability is strong.
Automatic-lifting type threshold device of the present utility model, comprises the spill threshold pedestal that is arranged under ground line and is arranged at the elasticity step that pedestal can stretch up and down along ground line;
Further, described elasticity step comprise activity be embedded at panel in threshold pedestal and be arranged at panel under elastomeric element;
Further, described elastomeric element comprises spring and is sheathed on upper bush and the lower sleeve of both ends of the spring respectively, and described upper bush bore is arranged to be greater than or less than lower sleeve bore;
Further, described threshold pedestal comprises trough-shaped base and the erection support be fixedly connected with lower sleeve be fixedly installed on base;
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, also weather strip is provided with between the door that described threshold is mated closedown.
The beneficial effects of the utility model: automatic-lifting type threshold device of the present utility model, by the pre-buried skeleton in ground, and this skeleton and whole equipment room skeleton are connected as a single entity, pre-buried skeleton is fixed automatic lifting threshold, the lifting of threshold realizes mainly through the contractility of three groups of springs, that is: when equipment passes through from threshold, according to weight of equipment, threshold is depressed into about ground level, after equipment leaves threshold, threshold is by its own resilient, threshold recovers increasing state, now threshold and inlet/outlet are connected as a single entity, if be provided with weather strip on door limit, then threshold and inlet/outlet can form a confined space, also can play dust-proof simultaneously, the effects such as sound insulation.

Detailed description of the invention
Fig. 1 is the cross-sectional view of automatic-lifting type threshold device of the present utility model in elasticity step reduction situation;
Fig. 2 is top view of the present utility model; Fig. 3 is the A-A structural representation under the elasticity 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, comprise the spill threshold pedestal 2 be arranged under ground line 1 and be arranged at the elasticity step 3 that pedestal 2 can stretch along ground line about 1; Need to smoothly pass threshold for some equipment, the process of the situation of jolting can not be there is, when opening behind the door, easily threshold step 3 can be depressed into slowly by equipment self-weight or artificial external force and about flush height with ground, allowing equipment pass through threshold stably.
In the present embodiment, described elasticity step 3 comprises activity and is embedded at the panel in threshold pedestal 2 and the elastomeric element 4 under being arranged at panel; Panel stretches along threshold pedestal 2 groove longitudinal (vertical threshold pedestal 2 direction) under the driving of elastomeric element.
In the present embodiment, described elastomeric element 4 comprises spring 41 and is sheathed on upper bush 42 and the lower sleeve 43 at spring 41 two ends respectively, and described upper bush 42 bore is arranged to be greater than or less than lower sleeve 43 bore; Upper bush 42 and lower sleeve 43 can under stress axial relative motion to coincidence status.
In the present embodiment, described threshold pedestal 2 comprises trough-shaped base 5 and the erection support 6 be fixedly connected with lower sleeve 43 be fixedly installed on base; Erection support 6 is for fixing lower sleeve 43 and by vertical pressure supporting fixing elasticity step 3.
In the present embodiment, described erection support 6 is π shape part, fixing trough-shaped base 5 rising wood of wing plate overlap joint of described π shape part; Structure is simple, is easy to install and operation, and the wing plate 61 of π shape part is fixed on trough-shaped base 5 by screw.
In the present embodiment, described trough-shaped base 5 is provided with bearing pin spacing hole; Expense axle spacing hole on threshold trough-shaped base 5, reaches and controls threshold heave amplitude.
In the present embodiment, described trough-shaped base 5 is fixedly installed on doorframe skeleton; By the pre-buried skeleton 8 of ground 7, and this skeleton and whole equipment room skeleton are connected as a single entity, and pre-buried skeleton 8 fixes automatic lifting threshold, and the lifting of threshold realizes mainly through the contractility of three groups of spring members 4, for switch gate position, door limit 9 as shown in the figure.
In the present embodiment, between the door that described threshold is mated closedown, be also provided with weather strip.After threshold raises, threshold can closely cooperate with the weather strip on door limit, thus ensure that equipment room has the Functional Requirements such as high seal, dust-proof, sound insulation and lucifuge.
