Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the invention provides on a kind of high-strength multifunctional safety protective door, including " C " shape
Side frame body 20, protective door 30 and lower side frame body 40, the bottom of upper side frame body 20 is provided with the sliding rail 23 for raising up, institute
The number for stating protective door 30 be two and be fixedly arranged at the upper side can along sliding rail 23 slide slide mechanism 70, it is described on
Side frame body 20 is internally provided with the drive mechanism of traction slide mechanism 70, and the drive mechanism includes annular rack 53, the ring
The upper and lower two-layer direction of motion is conversely, the upper and lower two-layer of the annular rack 53 has been respectively fixedly connected with when shape tooth bar 53 is rotated
Link 60 and lower link 61, the upper link 60 and lower link 61 respectively with the skate machine on corresponding protective door 30
Structure 70 is fixedly connected.Drive mechanism uses rack-driving in the technical scheme, using annular rack upper and lower two in rotation process
Layer is turned to conversely, be connected with link respectively, so as to drive corresponding protective door to open or close motion, to fan doors same due to two
It is slide construction, its unfolding mode is more flexible, opening speed is faster.
Further, the drive mechanism includes motor 50, driving wheel 51 and driven pulley successively according to gear sequences
52, the engagement of the annular rack 53 is connected between driving wheel 51 and driven pulley 52.The present solution provides a kind of specific knot
The drive mechanism of structure.
Further, the inner side of the upper side frame body 20 is fixedly installed two symmetrical installing plates 21, the installation
Bar shaped backboard 22 is provided with plate 21, the driving wheel 51 and driven pulley 52 are respectively fixedly disposed at the bar shaped backboard of corresponding side surface
On 22.In the preferred scheme, installing plate 21 is the installation site that the internal reservation of upper side frame body 20 goes out, first by driving wheel 51 when using
It is installed on bar shaped backboard 22 with driven pulley 52, then bar shaped backboard 22 is fixed with installing plate 21, as needed selector bar
Distance between shape backboard 22, so as to improve the applicability to the annular rack 53 of different size.
Further, as shown in Figure 4, Figure 5, the inner side of the annular rack 53 includes the depressed part of uniform intervals distribution
531, protuberance 532 is formed between the adjacent recessed portion 531；The upside of the upper link 60 has bending part 601, the folding
The end of turn of bilge 601 has "T"-shaped embeded slot 604, and embeded slot 604 is divided and forms upside 602 and downside on the bending part 601
603, on the upper link 60 engaging annular rack 53 after, the embeded slot 604 of upper link 60 and the protrusion of annular rack 53
Portion 532 is chimeric to be coordinated.In the preferred scheme, annular rack 53 is embedding with embeded slot 604 by protuberance 532 with upper link 60
Close connection, realize being relatively fixed with upper link 60 in the rotation process of annular rack 53.
Above-mentioned annular rack 53 and upper link 60 in chimeric installation, first by upper link 60 bending part 601 it is embedding
The protuberance 532 that groove 604 is directed at annular rack 53 is closed, bending part 601 is then inserted into annular rack 53 along embeded slot 604
On, now the upside 602 and downside 603 of bending part 601 fit to two edge up and down of annular rack 53 respectively, realize chimeric solid
It is fixed.But, found when actually used, used along with the long-time of annular rack 53, it is solid with chimeric between upper link 60
Surely there is the trend for coming off, therefore locating slot 533 can be opened up on the protuberance 532 of annular rack 53, and connect on corresponding
The inner surface of downside 603 for connecing frame 60 opens up the positioning protrusion 605 coordinated with locating slot 533, is protruded with positioning by locating slot 533
605 snap fit, improves lateral confinement power of the annular rack 53 with upper link 60 in chimeric installation, prevents link
60 come off.
In above scheme, the structure design of lower link 61 can refer to link 60, and both differences are essentially consisted in down
It is opposite with upper link 60 that the embeded slot 604 of link 61 opens up direction.
Further, as shown in fig. 6, the slide mechanism 70 includes roller 73, the side of the roller 73 is provided with solid
Surely " L " shape contiguous block 71 is connected on protective door 30, and the both sides of the edge of the contiguous block 71 are connected with " C " shape fixed cover 72, described
Roller 73 is constrained between fixed cover 72 and contiguous block 71, and the upper link 60 is fixedly attached to the contiguous block of slide mechanism 70
On 71 sides.Roller 73 in the preferred scheme in same slide mechanism 70 can be one or more, and roller 73 can be adopted
Polyformaldehyde material is used, so as to mitigate protective door deadweight, reducing friction resistance, while be prevented from drive mechanism and leaking electricity and being delivered to
On protective door 30, security is more preferable.
Further, enhancing block 74 is downwardly extending away from the side for stating roller 73 on the fixed cover 72, it is described
Enhancing block 74 is fixedly attached on contiguous block 71.Traditional protective door according to similar upper guiding, the design of lower load-bearing,
" L " the shape contiguous block 71 for usually relying on slide mechanism is connected on protective door 30, and this can will cause larger bearing to contiguous block 71
Load, uses for a long time, and contiguous block 71 has the trend of aging deformation, therefore, being made by strengthening the design of block 74 in the preferred scheme
Stress balance of the contiguous block 71 in motion in slide mechanism 70, so as to improve the service life of slide mechanism 70, in use, this sets
, it is necessary to the side of sliding rail 23 in upper side frame body 20 opens up out avoidance and strengthens the bar shaped mating groove of block 74, the bar shaped matches somebody with somebody for timing
Close not shown in groove figure, it can do adaptability design according to the running orbit of enhancing block 74.
Further, the number of slide mechanism 70 is two on the single protective door 30, in the upper side frame body 20
The stage casing of sliding rail 23 is provided with the first limit induction device 80, and the lateral edges of the sliding rail 23 1 are provided with the second limit induction
Device 81, the upper link 60 and lower link 61 are connected respectively on the slide mechanism 70 of the first limit induction device 80,
The first limit induction device 80 and the second limit induction device 81 are mutually corresponded to and to fixation to the fixed cover 72 of slide mechanism 70
The close distance of set 72 is sensed.In the preferred scheme, the first limit induction device 80 and the second limit induction device 81 can be right
The opening and closing of protective door 30 carry out distance perspective should, and distance signal fed back into the controller in upper side frame body 20（Should
Not shown in controller figure, particular location is designed near the position of motor 50）, after being judged by controller
Control the rotational motion of motor 50.
Further, the lower surface of the protective door 30 is provided with road wheel 31, is provided with about in the lower side frame body 40
The walking track 41 of the transverse movement of beam road wheel 31, the road wheel 31 needs using the good structure of load bearing effect in design, with
The larger upper side frame body 20 of deadweight and protective door 30 are adapted to, walking track 41 coordinates with road wheel 31, the rolling to road wheel 31
Enter row constraint.
In such scheme, in order to improve the protection effect of the internal structure of upper side frame body 20, can be in the side of upper side frame body 20
The upper lid 10 of lid and drive mechanism.
Embodiments of the invention have been described in detail above, but the content is only presently preferred embodiments of the present invention,
It is not to be regarded as limiting practical range of the invention, all impartial changes made according to the scope of the invention and improvement etc. all should
Still belong within covering scope of the present invention.
