Abstract
The utility model belongs to the technical field of machinery and particularly relates to a position limiter, especially a novel position limiter for a roller shutter door. The novel position limiter comprises a casing, wherein a rotatable screw rod is arranged on the casing, one end of the screw rod is provided with an input gear, two screw nut slide blocks capable of controlling upward opening and downward closing are arranged on the screw rod, teeth are arranged on the surfaces of the screw nut slide blocks, and fixing sheets capable of stopping the circumferential rotation of the screw nut slide blocks are arranged in the casing. The novel position limiter has the advantages that the screw nut slide blocks can be enabled not to do circumferential movement through the fixing sheets, the noise is reduced, the movable block can be directly embedded into the slide nut slide blocks under the effect of compression springs, and the installation and the regulation are convenient.
Description
Technical field
The utility model belongs to field of mechanical technique, refers to especially a kind of stop, especially a kind of novel position limiter of rolling door.
Background technology
Rolling door is that the door sheet with the multi-joint activity is cascaded, and in fixing slideway, rotates the door of up and down centered by the spool of door top.Rolling door equally plays horizontal subdivision with the effect of wall, it is closed device, press button and safeties etc. and is partly formed by curtain plate, seat board, guide rail, bearing, spool, casing, control cabinet, door-rolling machine, stop, lintel, manual speed relieving, generally is arranged on the position that inconvenience employing wall is separated.Beijing red sun rises industry and trade Co., Ltd rolling door and is applicable to public place or the dwelling houses such as the business shop front, garage, market, hospital, industrial enterprise.Especially door opening is larger, and convenient, fast unlatching effect is played in the place of inconvenient installation ground door body.As being used for garage door, market fire resistance rolling shutter door, hangar door etc.Door is closed or the problem such as unlatching although existing rolling door can solve easily, and it still exists the some shortcomings part: 1, such as when closing or open, sound is always excessive, brings larger noise, the environment around having affected; 2, the stop of existing structure is loosely organized, and application life is short, causes many unreasonable factors such as use cost height.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reasonable in design, long service life, can guarantee the rolling door little stop of noise in use.
For achieving the above object, the utility model has adopted following technical proposal: a kind of novel position limiter of rolling door, comprise housing, described housing is provided with the screw rod that can rotate, one end of described screw rod is provided with input gear, and screw rod is provided with the nut slider that two difference can be controlled the up and down switch, and the nut slider surface is provided with teeth, it is characterized in that, described enclosure interior is provided with can the circumferential stator that rotates of hold-down nut slide block.
In the novel position limiter of above-mentioned rolling door, described stator is fixed on inner walls by nut.
In the novel position limiter of above-mentioned rolling door, described inner walls is provided with column, is provided with Compress Spring between stator and column.
In the novel position limiter of above-mentioned rolling door, described housing adopts the cast iron manufacturing.
Compared with prior art, the utility model has the advantage of: can guarantee that by stator nut slider does not circumferentially move, reduce noise, movable block directly in the inserted num slide block, facilitates install and adjust under the effect of Compress Spring.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is schematic perspective view of the present utility model.
In figure, housing 1, screw rod 2, gear 3, nut slider 4, stator 5, teeth 6, Compress Spring 7, column 8.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
as shown in Figure 1, a kind of novel position limiter of rolling door, comprise housing 1, described housing 1 is provided with the screw rod 2 that can rotate, one end of described screw rod 2 is provided with input gear 3, screw rod 2 is provided with the nut slider 4 that two difference can be controlled the up and down switch, input gear 3 is when rotating, it drives screw rod 2 rotations, at this moment nut slider 4 is just ceaselessly controlled switch or lower switch at mobile on screw rod 2 so that nut slider 4, in this process, nut slider 4 may ceaselessly circumferentially move, on the contrary noise is excessive, these two nut sliders 4 respectively can nut slider 4 surfaces be provided with teeth 6, housing 1 inside be provided with can the hold-down nut slide block 4 stators 5 that circumferentially rotate, can guarantee that by stator 5 nut slider 4 is only moving axially, do not make excessive noise, described stator 5 is fixed on housing 1 inwall by nut, described housing 1 inwall is provided with column, be provided with Compress Spring 7 between stator 5 and column, described housing 1 adopts the cast iron manufacturing.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
