Abstract
The utility model discloses an insulating sleeve for a railway fastener. The insulating sleeve comprises an insulating sleeve body made of insulating materials. The insulating sleeve is characterized in that the insulating sleeve body is hollow, the wall of the insulating sleeve body is spiral so that the outer wall of the insulating sleeve body can be provided with external threads used for being screwed into a rail and the inner wall of the insulating sleeve body can be provided with internal threads for a sleeper bolt to be screwed and fixed. The insulating sleeve is hollow and the wall of the insulating sleeve is spiral so that the external threads and the internal threads can be arranged, the external threads can be directly screwed into the rail, the internal threads can be used for screwing the sleeper bolt, the force stressed on the sleeper bolt is transferred to the wall of the insulating sleeve body, and the wall transfers the force to the rail. Accordingly, stress on the insulating sleeve body is reduced, and the service life of the insulating sleeve body is prolonged.
Description
Technical field
The utility model relates to rail fastener field, particularly a kind of rail fastener insulation sleeve.
Background technology
Existing rail fastener assembly generally comprises rail, rail pad, sleeper bolt, spring, gauge apron, base plate, elastic bottom plate pad and insulation sleeve, insulation sleeve is arranged on rail in advance, be arranged on successively rail pad, base plate and elastic bottom plate pad under rail, screw by gauge apron and the spring of sleeper bolt with both sides again, with fixing rail, sleeper bolt screws in the effect that fixation assembly is played in insulation sleeve inside.But in prior art, be subject to huge impact force due to rail in train travelling process, cause sleeper bolt also stressed huge, sleeper bolt passes to insulation sleeve with power, because insulated conduit has damage or slight crack occurs, reduce its insulating properties, cause the train operation potential safety hazard.
In sum, for shortcomings and deficiencies of the prior art, need especially a kind ofly can bear enormous impact power and the significant insulation sleeve of insulation effect, to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of rail fastener insulation sleeve, and this insulation sleeve can coordinate and have the enormous impact of bearing power and the characteristics such as insulation effect is remarkable well with sleeper bolt.
The technical problem that the utility model solves can realize by the following technical solutions:
The rail fastener insulation sleeve, comprise the insulation sleeve body made from insulation materials, it is characterized in that, described insulation sleeve body is hollow form, the tube wall of described insulation sleeve body be helical form so that the outer wall of insulation sleeve body has to screw in the external screw thread of rail, inwall has for sleeper bolt and screws in fixing internal thread.
In a kind of preferred embodiment of the present utility model, the upper and lower of described insulation sleeve body all arranges some edges.
In a kind of preferred embodiment of the present utility model, the internal diameter of described insulation sleeve body is 18mm, and external diameter is 36mm.
Owing to having adopted technical scheme as above, the utility model is that hollow form and tube wall are helical form, make it have internal and external threads, can directly screw in rail, and internal thread can screw in for sleeper bolt, and the suffered power of sleeper bolt is transferred to insulation sleeve body tube wall, and tube wall passes to rail with power, weaken the force-bearing situation of insulation sleeve body, extended the application life of insulation sleeve body.Some edges of the upper and lower of insulation sleeve body setting simultaneously can further be fixed on the insulation sleeve body in rail, the difficult displacement, and adopting polyamide 6 and polyamide 66 mixed material to make has increased intensity of the present utility model and insulating properties.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the longitudinal sectional drawing of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to illustrated in figures 1 and 2, the advantage such as rail fastener comprises the insulation sleeve body 100 that adopts polyamide 6 and polyamide 66 mixed material to make with insulation sleeve, have hardness large, and insulating properties are good can be born enormous impact power.
The upper and lower of insulation sleeve body 100 all circumferentially is evenly equipped with four edges 121,122, and edge 121,122 engages with the interior default draw-in groove of rail installing hole, further insulation sleeve body 100 is fixed in rail.
Sleeper bolt screws in insulation sleeve body 100 inner chambers, the suffered power of sleeper bolt is transferred to insulation sleeve body 100 tube walls 110, tube wall 100 passes to rail with power, has weakened the force-bearing situation of insulation sleeve body 100, extends the application life of insulation sleeve body 100.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
