Brief description of the drawings
Fig. 1 is the schematic diagram of protective shielding door described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, protective shielding door described in the utility model, including guide groove 2 and supported by the guide groove 2
Door body 1 is shielded, the lower edge of the shielding door body 1 is provided with multiple support guide wheels 11, the support guide wheel 11 is described
Moved in guide groove 2 and support the shielding door body 1 to close or open along the guide groove 2.
In order to make the work of shielding door body 1 relatively reliable, prevent from occurring in the state of shielding door body 1 has been switched off
Non-artificial to open by mistake and (loosen and disengage), the utility model is fixedly installed rack 12 on the upper edge of the shielding door body 1.With
Corresponding to, fixed motor 3 and movable rotation fastener 4 are additionally provided with the top of the shielding door body 1
(motor 3 and movable rotation fastener 4 can be installed in the doorframe on shielding door body 1 top).
As shown in figure 1, the output shaft 31 of the motor 3 is coaxially connected with gear 32, the gear 32 and the tooth
Bar 12 coordinates；When the motor 3 rotates, its output shaft 31 drives the gear 32 to rotate and make the shielding door body
1 reach is closed or rear move is opened.The movable rotation fastener 4 includes liftable wheel shaft 41, on the wheel shaft 41
Fixed cover is provided with involute shape gear 42, and the involute shape gear 42 coordinates with the rack 12.When the shielding door body 1
When reach is closed, the involute gear 42 engages with the rack 12 and is driven and rotated forward by the rack 12, with right
The rack 12, which gradually imposes, to be supported pressure (i.e. involute gear at initial stage 42 and the rack 12 coordinates but not to rack 12
Impose and support pressure, with the reach of shielding door body 1, rack 12 can drive the involute gear 42 to synchronize rotation,
Again because it is involute-type, therefore its teeth can gradually compress rack 12, namely rack 12 is gradually imposed and supports pressure, so as to
Effectively prevent from shielding door body 1 in the state of having been switched off again by non-artificial opening by mistake).Moved after the shielding door body 1
During opening, the involute gear 42 engages with the rack 12 and is driven and rotated backward by the rack 12, described gradually to open
Line gear 42 to the rack 12 support pressure fade away (this process with it is foregoing gradually compaction process on the contrary, not going to live in the household of one's in-laws on getting married herein
Chat).
In the utility model, the movable rotation fastener 4 also includes two pieces of fixed supported slabs 43 being oppositely arranged,
Offer vertical elongated hole 431 on the fixed supported slab 43, the both ends of the wheel shaft 41 be fed through respectively the vertical elongated hole 431,
And it can be moved up and down along the vertical elongated hole 431；Also include the top spring 432 for being respectively arranged at two pieces of outsides of fixed supported slab 43, institute
State top spring 432 wheel shaft 41 is imposed and downward support power.In the utility model, the involute gear 42 on the wheel shaft 41
To rack 12 support pressure it is ensured that effectively prevent from shielding door body 1 not the non-artificial factor of reason and open by mistake and open, meanwhile, and not
The normal reach of shielding door body 1 can be hindered, which to close, (if wheel shaft 41 can not move up, then can directly affect shielding door body 1
Normal switching-off).Therefore, the top spring 432 of setting is especially necessary.The top spring 432 of appropriate size can be specifically selected according to field condition.
In the utility model, the pressure of supporting to rack 12 is lost in order to prevent involute gear 42 from loosening, also enters one
Step is provided with the elastic push rod 5 for being used for fixing the teeth that involute shape gear 42 is stated in residence.The free end quilt of the elastic push rod 5
Stiff spring 52 draws and is resisted against the teeth of the involute gear 42；The opposite face of the stiff spring 52 is provided with drawing
Line 51, when the bracing wire 51 is pulled by external force, the free end of the elastic push rod 5 is pulled up and departs from the involute gear
42 teeth.That is, as shown in figure 1, when shielding the reach closing of door body 1, the involute gear 42 is in inverse
The state that hour hands rotate, then, although elastic push rod 5 is resisted against the teeth of the involute gear 42, and without prejudice to gradually opening
Line gear 42 rotates counterclockwise, that is, does not influence involute gear 42 and impose rack 12 to support pressure；On the contrary, ought gradually it open
When line gear 42 is intended to rotate clockwise (i.e. the involute gear 42 no longer imposes to rack supports pressure), it is necessary to pass through bracing wire
51 pull elastic push rod 5, disengage it from the teeth of involute gear 42, in order to which involute gear 42 is able to turn clockwise
It is dynamic.
In the utility model, it is also a housing for shielding the accommodating chamber 6 of door body 1；The accommodating chamber 6 is recessed in wall
Inside, the side of the accommodating chamber 6 have the opening 61 passed in and out for the shielding door body 1；The guide groove 2 extend into institute along ground
State in accommodating chamber 6.Further, in order to maintain shield door body 1 pass in and out accommodating chamber balance, also it is described opening 61 both sides
Support runner 62 is arranged oppositely, and the support runner 62 of the both sides supports two sides that shielding door body 1 is stated in residence respectively
Face 13.
In protective shielding door described in the utility model, by setting movable rotation fastener so that with
The reach for shielding door body is closed, and the shielding door body can gradually be applied pressures below, so as to make the shielding door body not miss
Open, so as to actually reach the effect of security protection.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
