Description
Technical field
The utility model relates to a kind of automatic door field, particularly a kind of automatic door strainer of band synchronously that is used for.
Background technology
Existing auto-door driving mechanism generally comprises motor and reducing gear thereof, driving gear, band and driven gear synchronously, band ringwise synchronously, and be meshed with driving gear that is positioned at its two ends and driven gear respectively, the drive block of door leaf promptly is arranged on synchronously and is with, during work, motor drives the driving gear rotation through reducing gear, drives synchronous Tape movement then.Consider the reliability and the accuracy of transmission of power, take to synchronously toward adopting flexible tape, and the tensioning degree of band can directly influence the application life of synchronous band and the reliability that door leaf opens and closes synchronously, therefore when mounted or in use for some time, must be regulated the tensioning degree of synchronous band, generally this is to realize by the position of regulating driven gear, in traditional work, need driven gear is subjected to displacement and the synchronous band of tension simultaneously, it be very inconvenient to operate.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of operation to be used for the automatic door strainer of band synchronously easily at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this strainer that is used for the synchronous band of automatic door includes base, regulate push pedal and gear, regulating the mode that push pedal can regulate displacement with base relatively is fixed on the base, gear then is fixed on to be regulated in the push pedal, it is characterized in that, described adjusting push pedal has a kink upwards at afterbody, and the afterbody of base also has a kink and being positioned at after the kink of regulating push pedal upwards, the head of one adjusting rod and afterbody are inserted in respectively in the aperture corresponding on two kinks, wherein but the aperture on the head relative adjustment push pedal kink of adjusting rod moves and is spacing by the flange that is positioned at the adjusting rod end, the afterbody of adjusting rod then with the kink of base on aperture be threaded mutually, one preloading spring is set in adjusting rod on the position between two kinks, the head of preloading spring offsets with the kink of regulating push pedal, afterbody be arranged on the supermedial flange of adjusting rod and offset.
Can have mounting hole in the described adjusting push pedal, and pass this mounting hole by screw and be threaded mutually, like this, tighten screw and be about to regulate the relative base of push pedal and fix, can make and regulate push pedal and move relative to base and unscrew screw with screw on the base.
The described flange that is positioned at the adjusting rod end can be formed by the collar that this place is set, and also can adopt other prior aries.
The supermedial flange of described adjusting rod can be formed by the packing ring that is arranged on this place, also can adopt other prior aries.
Described gear can be fixed on various prior aries and regulate in the push pedal, but preferably can be in the following ways: the central axis of gear has the downward extension that a periphery is carved with screw thread, this downward extension is passed and is regulated aperture corresponding in the push pedal, and be connected with a nut, base then has the hole to hold this downward extension and nut in corresponding position.
Compared with prior art, the utility model is by regulating the adjusting rod that the band preloading spring is set between push pedal and the base, make and regulate push pedal when unclamping with base, under the effect of preloading spring, need not manually automatically the area gear and moves forward, make synchronous band tensioning, thereby realize the purpose of easy manipulation.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of the utility model embodiment.
Fig. 2 is the vertical view (preloading spring is in the pretension state and adds the part of being decorated with synchronous band) of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, being used for the synchronous strainer of being with of automatic door includes base 1, regulates push pedal 2, gear 4 and adjusting rod 7;
Regulate in the push pedal 2 and have mounting hole 21, and pass this mounting hole 21 by screw 3 and be threaded mutually, like this, tighten screw 3 and be about to regulate push pedal 2 relative bases 1 and fix, adjusting push pedal 2 is moved relative to base 1 and unscrew screw 3 with screw on the base 1; And regulate push pedal 2 and have a kink 22 upwards, and on this kink 22, have an aperture at afterbody;
The periphery that has the central axis of gear 4 is carved with the downward extension 41 of screw thread, this downward extension 41 is passed and is regulated aperture corresponding in the push pedal 2, and be connected with a nut 9, thereby gear 4 is fixed in the adjusting push pedal 2, and base 1 then has hole 11 to hold described downward extension 41 and nut 9 in corresponding position;
The afterbody of base 1 also has a kink 12 and being positioned at after the kink 22 of regulating push pedal 2 upwards, and has a screw on this kink 12;
