Abstract
The utility model discloses a displacement restrictor positioning device of an electric rolling screen door machine, which comprises a microswitch, a guide screw, a slide block, and a gearing wheel and a displacement restrictor seat on the projecting end of the guide screw, wherein the slide block is provided with an inner screw which can be moved on the guide screw. The technical proposal is that the excircle of the slide block is provided with a deep tooth slot which is evenly arranged, an upper front extending plate of a Z-shaped guide board is inserted into the tooth slot of the slide block, and a lower rear extending plate is fixed on the displacement restrictor seat. The guiding of the displacement restrictor positioning device is changed from the existing guiding groove to the guide board, and the stability and the reliability of the guiding are improved, and the slide block is modified from the existing assembled component to an integral type. The utility model has the advantages of simple structure, high reliability of positioning, simple manufacturing technique and convenient installation and adjustment, whose materials are replaced by POM plastic and production cost is greatly lowered.
Description
Affiliated technical field
The utility model relates to electric rolling door device, specifically the stop positioner of electric rolling door device.
Background technology
Adopt the guide groove guiding in the existing roller shutter door machine stop positioner, slide block on the screw mandrel is assembled by the screw location by slide body and nut, its complex structure, reliability of positioning is poor, slide body is that kirsite, nut are copper alloy, material is more valuable non-ferrous metal, the manufacturing cost height.
Summary of the invention
In order to overcome the above deficiency of prior art, the purpose of this utility model provides the roller shutter door machine stop positioner of a kind of stability of simple in structure, location and reliability height, low cost of manufacture.
The utility model roller shutter door machine stop positioner comprises: the travelling gear of microswitch, screw mandrel, slide block, screw mandrel external part and stop seat, slide block has internal thread and can move on screw mandrel, its technical scheme is: the slide block cylindrical is provided with equally distributed dark teeth groove, the sheet that protracts on the Z-shaped guide plate insert this slide block teeth groove, it stretches sheet after down and is fixed on the stop seat.
The beneficial effects of the utility model are:
(1) guiding with the stop positioner changes guide plate into by existing guide groove, and the stability of guiding and reliability are improved.
(2) slide block with the stop positioner changes whole single type into by existing assembling assembly, the reliability height of simple in structure, location, and its material can be replaced by the POM plastics, and cost reduces significantly,
(3) it is convenient that manufacturing process is easy, installation is adjusted, and simplifies the stop detent mechanism.
Description of drawings
Below in conjunction with accompanying drawing and preferred implementation the utility model is further elaborated.
Fig. 1 is the structural representation of the utility model roller shutter door machine stop positioner;
Fig. 2 is the lateral view of slide block in the roller shutter door machine stop positioner;
Fig. 3 is the structural representation of roller shutter door machine stop positioner centering guide.
Among the figure: stretch sheet, 3-screw, 4-stop seat, 5-screw mandrel, 6-microswitch, 7-travelling gear after under the sheet that protracts on 1-slide block, 11-teeth groove, 2-guide plate, the 21-, the 22-.
The specific embodiment
As Fig. 1, shown in Figure 3, the utility model roller shutter door machine stop positioner comprises: the travelling gear (7) of microswitch (6), screw mandrel (5), slide block (1), screw mandrel external part and stop seat (4), slide block has internal thread and can move on screw mandrel, its technical scheme is: slide block (1) cylindrical is provided with equally distributed dark teeth groove (11), the sheet (21) that protracts on the Z-shaped guide plate (2) insert this slide block teeth groove, it stretches sheet (22) after down and is fixed on the stop seat (4) by screw (3).The monolithic slide block (1) of this device is installed on the screw mandrel (5), screw mandrel is by gear (7) transmission, the direction of motion of slide block is controlled by guide plate, slide block can be finely tuned its orientation by the teeth groove on its cylindrical, and left and right sides slide block (1) contacts the impulse stroke that can cut off circuit control door-rolling machine with the contact of microswitch (6).
As preferred forms of the present utility model, as shown in Figure 2, a plurality of teeth groove (11) that evenly distribute on described slide block (1) cylindrical, the notch of this teeth groove is narrow, bottom land is wide, and its groove depth is 2～5mm.
As improvement of the present utility model, stretch sheathed spring on screw (3) bar of sheet after under resting guide, make guide plate (2) on the sheet (21) that protracts can draw back and break away from slide block teeth groove (11), the position of adjusting slider quickly and easily.
Claims (3)
