Description
Technical field
The utility model relates to a kind of railway equipment, relates in particular to a kind of railroad sleeper and uses the plastic fastener protective cover.
Background technology
The secure component that is used for connection and fastening each railway equipment (like rail and sleeper) on the railroad sleeper; Measure to its protection normally is coated with antirust oil on these secure components; It is not installed additional other forms of coating member; But because the erosion of natural cause such as sunshine and rainwater for a long time; Secure component can occur and be prone to aging, loosening and antirust oil is prone to by the situation of harm railway traffic security of operation such as rain drop erosion, this just requires jede Woche railroad maintenance personnel that antirust wet goods maintenance work is checked and brushed to these secure components, has caused manpower and the waste of producing material.
The utility model content
The technical problem that the utility model will solve has been to provide a kind of and has been used to protect the railroad sleeper of the secure component on the railroad sleeper to use the plastic fastener protective cover.
The technical scheme that the utility model adopts is: a kind of railroad sleeper is used the plastic fastener protective cover; It is characterized in that: comprise box body and fastening shell fragment, said box body is provided with cavity, and said fastening shell fragment is located on the cavity wall; And be provided with crack between the cavity wall, fastening shell fragment inwall is provided with fin.
Said fastening shell fragment inwall is provided with three fins, and is triangular in shape, and middle fin is high than the both sides fin.
Fin on the said fastening shell fragment inwall, both sides fin height is 13 millimeters, middle fin is high 2 millimeters than the both sides fin.
Said fastening shell fragment is located on the cavity wall of box body symmetry both sides, and is provided with crack between the cavity wall, and crack is wide to be 1.2 millimeters.
Said inboard wall of cartridge is provided with reinforcing rib.
Said box body outer wall is provided with handle.
Said handle outer wall is provided with screw thread.
Compared with prior art; The utlity model has following advantage: this kind railroad sleeper can play the secure component on the protection railroad sleeper with the plastic fastener protective cover effect is being set on the railroad sleeper; Simple to operate, easy for installation, cost of production is low; Reduced railroad maintenance personnel's the workload and the consumption of antirust oil, reached and practiced thrift manpower and the purpose of producing material.
Description of drawings
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the isometric front view of the utility model railroad sleeper with the plastic fastener protective cover.
Fig. 2 is the rear isometric view of the utility model railroad sleeper with the plastic fastener protective cover.
Fig. 3 is the full sectional view of the utility model railroad sleeper with the plastic fastener protective cover.
The specific embodiment
Come the utility model is carried out detailed explanation below in conjunction with specific embodiment.
As shown in Figure 1, a kind of railroad sleeper is used the plastic fastener protective cover, comprises box body 1, fastening shell fragment 2 and handle 3, and said box body 1 is provided with cavity 11, and said fastening shell fragment is located at box body 1 inwall symmetry both sides, and said handle 3 is located on the box body outer wall.
Said box body 1, fastening shell fragment 2 and handle 3 adopt metals or plastics to process.
1 of said fastening shell fragment 2 and box body are provided with crack 12, and crack 12 is wide to be 1.2 millimeters.
Said cavity 11, the widest part are 154 millimeters, and basic depth is 36.5 millimeters, is used to hold and protect the secure component on the railroad sleeper, especially screw and nut.
Said box body 1 outer wall is provided with handle 3, is used for dismounting and the use of handled easily personnel to this device.
Said handle 3 outer walls are threaded 31, are used for increasing operating personnel in dismounting and the use hand frictional force to this device.
As shown in Figure 2, said fastening shell fragment 2 inwalls are provided with three fins, and are triangular in shape; Fin 211 height in both sides are 13 millimeters, and middle fin 212 is high 2 millimeters than both sides fin 211, is used for box body 1 is fixed on railroad sleeper; In use, withhold box body 1 downwards, the stressed fastening shell fragment 2 that makes of fin produces elastic deformation; Withhold when accomplishing, fastening shell fragment 2 reaches the duty of fastening owing to the original shape of self elastic return.
As shown in Figure 3, said box body 1 inwall is provided with reinforcing rib 13, is used to increase the intensity of box body 1.
In addition; Except that the shape structure of above-mentioned fastening shell fragment 2; Similarly protect the plastic fastener protector of railroad sleeper secure component for other,, also belong to the protection domain of the utility model as long as adopted the operating principle of the dependence elastic deformation realization fastening of above-mentioned fastening shell fragment.
