Abstract
The invention discloses an elastic strip III type fastener insulation track gauge block which comprises an L-shaped insulation track gauge block, wherein the middle part of a sheet steel sleeve is sleeved with the L-shaped insulation track gauge block, and the L-shaped insulation track gauge block is protected by sleeving the L-shaped insulation track gauge block in the sheet steel sleeve, so that the purposes of preventing fracture and bending, prolonging the service life and reducing the production cost are fulfilled.
Description
Technical field
The present invention relates to a kind of track accessory, be specifically related to a kind of elastic fastener Insulation rail distance keeper.
Background technology
Elastic bar fastener Insulation rail distance keeper is a kind of accessory that rail is connected with sleeper, general is all to adopt the engineering plastics of high insulating property to make, and in use, it is very little that spring is withheld lifting surface area on track gauge block, easily cause track gauge block fracture, bending etc., and along with the variation of seasonal temperature, the performance of engineering plastics also can change, especially in summer, in addition the temperature of rail etc. is higher, cause engineering plastics deliquescing, reduced properties of product, also shortened application life.Also have Some Enterprises to add magnetic post in the both sides of spring, to address the above problem, but this kind of method production is more complicated, has increased cost of production.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of elastic fastener Insulation rail distance keeper, reach and prevented fracture and object bending, that increase the service life and reduce production costs.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of elastic fastener Insulation rail distance keeper, includes L-type Insulation rail distance keeper, and the middle part cover of L-type Insulation rail distance keeper has steel disc cover.
Preferably, described steel disc cover surface-coated has one deck antirust coat.
By technique scheme, the present invention, by L-type Insulation rail distance keeper being set in steel disc cover, realizes protection to L-type Insulation rail distance keeper, reaches and prevents fracture and object bending, that increase the service life and reduce production costs.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is that the master of the disclosed a kind of elastic fastener Insulation rail distance keeper of the embodiment of the present invention looks schematic diagram.
Numeral and the represented corresponding component title of letter in figure:

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The invention provides a kind of elastic fastener Insulation rail distance keeper; its operating principle is by L-type Insulation rail distance keeper being set in steel disc cover; L-type Insulation rail distance keeper is realized to protection, reach and prevent track gauge block fracture and object bending, that increase the service life and reduce production costs.
Below in conjunction with embodiment and detailed description of the invention, the present invention is further detailed explanation.
As shown in Figure 1, a kind of elastic fastener Insulation rail distance keeper, includes L-type Insulation rail distance keeper 1, and the middle part cover of L-type Insulation rail distance keeper 1 has steel disc cover 2, and the surface-coated of steel disc cover 2 has one deck antirust coat.
Concrete use step of the present invention is as follows: spring is withheld in the center of steel disc cover 2, made in use, active force is dispersed on whole steel disc cover 1, makes the non-deformability of whole L-type Insulation rail distance keeper 1 obtain enhancing; Simultaneously; because steel disc cover 2 wraps the both sides of L-type Insulation rail distance keeper, in use L-type Insulation rail distance keeper is realized to effectively protection, avoid L-type Insulation rail distance keeper 1 to occur fracture; also prevent in the time that temperature changes engineering plastics be heated deliquescing, distortion, extended its application life.And at surface-coated one deck antirust coat of steel disc cover 2, prevent that steel disc from overlapping that 2 long term exposure are oxidized in air, corrosion.
By above mode; a kind of elastic fastener Insulation rail distance keeper provided by the present invention; by L-type Insulation rail distance keeper being set in steel disc cover, L-type Insulation rail distance keeper is realized to protection, reach and prevent fracture and object bending, that increase the service life and reduce production costs.
Above-described is only the preferred embodiment of a kind of elastic fastener Insulation rail distance keeper disclosed in this invention; should be understood that; for the person of ordinary skill of the art; without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
1. an elastic fastener Insulation rail distance keeper, is characterized in that, includes L-type Insulation rail distance keeper, and the middle part cover of described L-type Insulation rail distance keeper has steel disc cover.
