Abstract
The utility model discloses a cavity damping nylon cushion board, a serial communication port, including the backing plate of glass fiber reinforced nylon material and with backing plate complex overlay, the backing plate with one side of covering cover plate contact is seted up flutedly, be provided with latticed strengthening rib in the recess, wherein, the backing plate with the overlay shape is unanimous. Anticorrosive and the light in weight of above -mentioned cavity damping backing plate, the installation is convenient, and structural strength is high, and the security is good.
Description
Technical field
The utility model is related to rail fastening antivibration area, more particularly to a kind of hollow vibration damping nylon back plate.
Background technology
Existing subway rail fastener structure includes elastic insert under iron chair and iron chair.Iron chair typically adopts cast iron material
Matter, general surface adds electrostatic spraying antirust treatment.In Long-Time Service, due to rainwater, air, oxygen effect, using process
The antirust coat on middle iron chair top layer gradually comes off, and Cast Iron Surface starts to get rusty.Conventional for a long time, can produce on iron chair surface
Rust hole.When backing plate is rolled by train, easily at rust hole, cause stress riser, lead to backing plate to crack and rupture, impact
Traffic safety.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provide one kind to be difficult to get rusty and
Structure stronger hollow vibration damping nylon back plate replaces iron chair.
For solving above-mentioned technical problem, technical solution adopted in the utility model is：A kind of hollow vibration damping nylon back plate,
Backing plate including glass fiber enhanced nylon material and the cover plate with the cooperation of described backing plate；Described backing plate is contacted with described cover plate
Side opens up fluted, is provided with latticed reinforcement in described groove；
Wherein, described backing plate is consistent with described covering plate shape.
It is characterised in that described backing plate also includes absorbing particle in one embodiment；Described absorbing particle is arranged on described
In latticed reinforcement.
In one embodiment, described absorbing particle is ball.
In one embodiment, described backing plate and described cover plate are provided with the buckle structure matching, described backing plate and institute
State cover plate to connect by described buckle structure.
In one embodiment, after described cover plate installed by described backing plate, bottom surface generally plane.
Have the beneficial effects that using produced by technique scheme：Above-mentioned hollow vibration damping nylon back plate, using nonmetallic
Material instead of metallic material, can be solved using glass fiber enhanced nylon material (such as glass fiber enhanced nylon 66) backing plate through overtesting
The corrosion problem of backing plate in prior art, and do not reduce intensity in use.And the density of glass fiber enhanced nylon only has cast iron
1/6th, compression strength with cast iron quite can effectively reduce the weight of global facility, improves the facility installed
Property.And pass through to arrange the structural strength that latticed reinforcement can improve vibration attenuation pad further, improve security.

Fig. 2 is the front view of Fig. 1；
Fig. 3 is the upward view of Fig. 2；
Fig. 4 is the front view of Fig. 1；
Fig. 5 is the structural representation of cover plate in the utility model one embodiment of hollow vibration damping nylon back plate.
Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is described in further detail.
Referring to Fig. 1 to Fig. 5, in an embodiment, hollow vibration damping nylon back plate can include glass fiber enhanced nylon material
Backing plate 100 and the cover plate 200 with backing plate 100 cooperation.The side that backing plate 100 is contacted with cover plate 200 opens up fluted 101.
It is provided with latticed reinforcement 110 in groove 101.Wherein, backing plate 100 is consistent with cover plate 200 shape.
Replace metal material using nonmetallic materials, adopt glass fiber enhanced nylon material (such as fiberglass reinforced through overtesting
Nylon66 fiber) backing plate 100 can solve the problems, such as the corrosion of backing plate in prior art, and do not reduce intensity in use.And glass
The density strengthening nylon only has 1/6th of cast iron, and compression strength with cast iron quite can effectively reduce global facility
Weight, improve install convenience.Glass fiber enhanced nylon has that intensity is high, corrosion resistant characteristic, in Long-Time Service, without
Worry etching problem, and ageing resistace is excellent, Long-Term Properties will not reduce.After rail fastener is applied, can change
Become the general structure of current fastener, save national steel, and line noise can be played with good control.
Further, backing plate 100 can also include absorbing particle (figure is not marked).Absorbing particle can be arranged on latticed adding
In strong muscle 110.By particle-filled for absorbing in the latticed reinforcement 110 of backing plate 100, it is loaded on cover plate 200, receiving
During the vibrations conduction of train, vibrations can be absorbed, vibrations be changed into heat absorption release, plays the effect of vibration and noise reducing.One
In individual embodiment, absorbing particle can be ball, and cost is relatively low, and realizes simple.
In addition, backing plate 100 and cover plate 200 can be provided with the buckle structure (figure is not marked) matching.Backing plate 100 He
Cover plate 200 is linked together by changing buckle structure.
Preferably, after cover plate 200 installed by backing plate 100, bottom surface generally plane.Specifically, backing plate 100 and cover plate
The opposite flank generally plane of the side of 200 contacts.The opposite flank of the side that cover plate 200 is contacted with backing plate 100 is also
Plane.The latticed reinforcement 110 of backing plate 100 is all covered by cover plate 200, thus ensureing that the lower surface of backing plate 100 is also
Smooth.And cover plate 200 has certain degree of hardness, the power of latticed reinforcement 110 can be divided into plane stress, will not be right
Under soft plate, elastic layer produces shear action, does not result in the problem that under plate, elasticity is cut off.
Above-mentioned hollow vibration damping nylon back plate, by designing the structure of backing plate, redundance is hollowed out, and assistant reinforcement muscle knot
Structure, makes backing plate thickness uniformity everywhere, in forming process, shrinks uniformly, will not produce contracting hole that inhomogeneous cooling causes etc.
Defect.And replace metal material using nonmetallic materials, adopt the backing plate 100 of glass fiber enhanced nylon material permissible through overtesting
Solve the problems, such as the corrosion of backing plate, and do not reduce intensity in use, the density of nylon only has 1/6th of cast iron, pressure resistance
Degree with cast iron quite can effectively reduce the weight of global facility, improve the convenience installed.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in the utility model
Protection domain within.
