On the groove root 19 of the secondary teeth groove 5 of the main teeth groove 4 of tooth plate and secondary tooth plate（It is not provided with major and minor fixing groove 12,13）, and overlap respectively
In on ratcheting secondary rack 6 and main rack 3, can equally cause both produce displacement slot be the structure of annular seal space 10.
Certainly, the structure of above-mentioned main tooth plate cover plate 7 and secondary tooth plate cover plate 8 can be with as shown in fig. 6, be arranged to fix respectively
In on main teeth groove and secondary teeth groove（Or in）Splitted cover board 14, these splitted cover boards are equally overlapped in corresponding secondary rack 6 and main tooth
On bar 3, it is also possible that the displacement slot formation annular seal space 10 that both produce, and reach and effectively overcome displacement slot by sandstone and rubbish
Occur the problem of filled.
The structure for equally constituting annular seal space as shown in Figure 7,8 can also be the main tooth plate 1 of composition, secondary, the main teeth groove of secondary tooth plate 2
Groove top be the structure of Baltimore groove 18 that is washed out by lathe（Above-mentioned secondary, main teeth groove 5 and 4 groove top is constituted to connect to be formed）,
I.e. corresponding major and minor rack 3,6 forms the sealing cavity configuration for preventing that sandstone rubbish from entering therewith.
--- in the structure of above-mentioned sand prevention noise reduction retractor device, in order to further improve the sealing effectiveness of annular seal space,
The end of main tooth plate cover plate 7 and secondary tooth plate cover plate 8 or splitted cover board 14 is provided with sealing mechanism 17, naturally it is also possible in above-mentioned main tooth
The end of bar 3 and secondary rack 6 sets the sealing mechanism 17.
--- being provided with above-mentioned main tooth plate or the corresponding anchor structure 15 of secondary tooth plate can be to its downward absorption affinity
Permanent magnet 16.The permanent magnet gives retractor device one flexible vertical force effect, when beam body and beam body or beam body and abutment
Between when producing the vertical discrepancy in elevation, the main tooth plate of permanent magnet adsorbing is allowed to effectively fit with road surface, it is ensured that the planarization of bridge floor, effective gram
Take vehicle by when noise is produced due to the up-down vibration of tooth plate, it is ensured that the safety and comfortableness of traveling.
In I-I and II-II diagrammatic cross-section of three kinds of structures of above-mentioned sand prevention noise reduction retractor device is constituted, except in composition
The structure for stating the main tooth plate cover plate 7 in figure and secondary tooth plate cover plate 8 changes outer, the structure of other such as secondary, main teeth groove or bar
Substantially it is similar, can be mutually with reference to using；The purpose of the utility model, which is just to provide composition, includes the integral main tooth shown in Fig. 1
The major and minor tooth plate cover plate 14 and Fig. 7 of split shown in plate cover plate 7 and secondary tooth plate cover plate 8, Fig. 6, the conjoined structure 11 shown in 8
（Equivalent to main tooth plate cover plate 7 and secondary tooth plate cover plate 8）Baltimore groove 18, its purpose is just so that the major and minor tooth between two pieces of tooth plates
The displacement slot that bar is formed between secondary, main teeth groove respectively is annular seal space, to overcome the intrusion of the rubbish grains of sand.
