Abstract
The utility model discloses a device for fastening two parts on an escalator or a moving sidewalk. The device comprises a first part and a second part which are fastened through the fit between bolts and nuts, the device further comprises a follow-up rotation proof plate arranged on one side of the first part, the second part is arranged on the other side of the first part, a plurality of through holes are formed on the follow-up rotation proof plate, a plurality of bolts and nuts are provided, the bolts are fixedly and respectively inserted in the through holes, the bolts penetrate the bolt through holes on the first and the second parts in sequence, and the nuts are matched with the extending parts of the bolts respectively. Therefore, when the nut on a bolt is screwed, the bolt can be prevented from rotating by the other bolts, so as to ensure smooth locking of the nuts, facilitate the connection and disconnection of the two parts, and improve assembly efficiency.
Description
Technical field
The utility model relates to the securing device of two parts on a kind of escalator or the moving sidewalk.
Background technology
On escalator or moving sidewalk, two parts are when carrying out connection by the bolts and nuts cooperation, need in bolt of rear end plate and the nut, turn another one again, could realize the fastening of two parts, but a side of parts or several sides operational space are very little or do not have substantially sometimes, like this when turning bolt or nut, be easy to take place the transfer of bolt or nut, then installation personnel will be spent a large amount of man-hours and remove to finish a connection request, also need spend same man-hour during the repair and maintenance dismounting, waste great amount of manpower.
Summary of the invention
The purpose of this utility model provides the device of fastening two parts of anti-transfer on a kind of escalator or the moving sidewalk.
For achieving the above object, the technical solution adopted in the utility model is: the securing device of two parts on escalator or the moving sidewalk, comprise by bolts and nuts and cooperate first parts that are fastened, second parts, this securing device also comprises the anti-transfer plate that is arranged on described first parts, one side, described second parts are arranged on the opposite side of described first parts, offer a plurality of perforation on the described anti-transfer plate, described bolts and nuts also have a plurality of, a plurality of described bolts fixedly are through respectively in a plurality of described perforation, described first parts of a plurality of then described screw bolt passes, bolt penetration hole on described second parts is combined with described nut on the position that passes.
Preferably, described nut is pressed on described second parts by packing ring.
Further preferably, described bolt is provided with spring washer, and described nut compresses described spring washer on described packing ring.
Preferably, the bolt penetration hole on described first parts or described second parts is for moving the perforation of regulating therein for described bolt.
Further preferably, described bolt penetration hole is the oval hole.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: on anti-transfer plate a plurality of bolts are set, when on a bolt, turning nut like this, other bolts on the anti-transfer plate are through in the bolt penetration hole on first parts, second parts, can prevent that this bolt from rotating, thereby nut can screw smoothly, same operation, can on all bolts on the anti-transfer plate, screw nut, realize being fastenedly connected of first parts, second parts, attended operation is convenient, and is same, disassembling section is also very convenient, promotes efficiency of assembling.
Description of drawings
Accompanying drawing 1 is the STRUCTURE DECOMPOSITION scheme drawing of a kind of specific embodiment of the present utility model;
Accompanying drawing 2 is looked scheme drawing for the master of a kind of specific embodiment of the present utility model;
Accompanying drawing 3 is the schematic top plan view of a kind of specific embodiment of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-3, the securing device of two parts on escalator or the moving sidewalk, comprise by bolt 1 and cooperate first parts 6 that are fastened with nut 5, second parts 7, be arranged on the anti-transfer plate 2 of first parts, 6 one sides, second parts 7 are arranged on the opposite side of first parts 6, as shown in fig. 1, second parts 7 are arranged on the outside of first parts 6, the open side of first parts 6 has obstacles such as civil engineering or other parts usually, tighten first parts if cause directly cooperating by bolts and nuts, second parts, then owing to be inconvenient to extend in the opening of first parts and fix bolt or nut, when causing screwing nut or bolt, bolt or nut are easy to transfer, can be pretty troublesome when connecting like this, be not easy to tighten, and in securing device of the present utility model, anti-transfer plate 2 is set, offer a plurality of perforation on the anti-transfer plate 2, bolt 1 also has a plurality of with nut 5, a plurality of bolts 1 fixedly are through in a plurality of perforation respectively, the head of bolt 1 is fixed by welding on the anti-transfer plate 2, and be arranged on the inboard of first parts 6, shown in Fig. 2 and 3, a plurality of then bolts 1 pass first parts 6 successively, bolt penetration hole on second parts 7 is combined with nut 5 on the position that passes.On anti-transfer plate 2, a plurality of bolts 1 are set, when turning nut 5 like this on a bolt 1, other bolts 1 on the anti-transfer plate 2 are through in the bolt penetration hole on first parts 6, second parts 7, can prevent that the above-mentioned bolt 1 from rotating, thereby nut 5 can screw smoothly, same operation can screw nut on all bolts 1 on the anti-transfer plate 2, realize being fastenedly connected of first parts 6, second parts 7, attended operation is convenient, equally, disassembling section is also very convenient, promotes efficiency of assembling.
In Fig. 1, the perforation on the anti-transfer plate 2 has two, two perforation upper and lower settings, and correspondingly, bolt 1 has two groups with nut 5.Because first parts 6, second parts 7 generally all have the matching requirements of certain size, thus generally can wide-bore or oval hole on first parts 6, second parts 7, can supply bolt 1 move adjusting therein, regulate the connection location of two parts.In Fig. 1, the oval hole on first parts 6 vertically is provided with, the oval hole horizontally set on second parts 7, and the connection location of being convenient to two parts can carry out laterally vertically regulating according to specific requirement.
In Fig. 2 and Fig. 3, nut 5 is pressed on second parts 7 by packing ring 3, and packing ring 3 is used to hide eyelet and increases the area that compresses of nut, prevents that second parts 7 from being swiped by nut.Bolt 1 is provided with spring washer 4, and nut 5 holddown spring packing rings 4 are on packing ring 3, and spring washer 4 is given 5 one elastic force of nut, pushes against nut 5, increases the friction force between the nuts and bolt, and it is loosening that nut is difficult for.
To sum up, in the securing device of anti-transfer, anti-transfer plate is set, a plurality of bolt are through in a plurality of perforation of anti-transfer plate, and pass bolt penetration hole on first parts and second parts successively, when turning nut like this on a bolt, other bolts can prevent the rotation of this bolt, guarantee the smooth locking of nut.This securing device is simple in structure, and cost is lower, and the bolt transfer phenomenon in the time of can effectively preventing the Assembly ﹠Disassembly parts has solved installation requirement, has improved efficiency of assembling.
