Description
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of railway communication leakage coaxial cable fixture.
Background technique
Along with urban rail transit in China technology is constantly improved development, train speed per hour grade improves constantly, according to the standard regulation of the railway communication leakage coaxial cable fixture of the railroad industry standard > > of the < < People's Republic of China (PRC) of in June, 2013 issuing and implementation, only reach the leakage coaxial cable fixture product ability on-line running that meets standard, based on current communication, leak cable installation situation, for no longer adapting to modernized railway communication needs in urban track traffic tunnel along traditional sling and jig of wall fixed communication leakage cable, more cannot meet the standard of railway communication leakage coaxial cable suspender, how communication being leaked to cable is fixed to and on tunnel, becomes a new technical barrier along wall.Current programme is to adopt common suspension clamp mode to fix, but because communication is leaked cable as installed circuit apart from growing (10Km), interval span is larger, communication is leaked cable and is subject to train travel to produce the object that the various factors such as air-flow and vibrations cannot reach fixed communication leakage cable, badly influences train traffic safety and railway communication guarantee.Therefore need to design a kind of in urban track traffic tunnel along wall fixation and be easy to install and need have super tough and tension against shock and there is the fixture of enough grip strength.
Model utility content
In order to solve the existing deficiency of above-mentioned technology, the utility model provides a kind of railway communication leakage coaxial cable fixture.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of railway communication leakage coaxial cable fixture, comprise base plate, supporting base, and base plate and supporting base are into a single integrated structure; Below the base plate of supporting base below, be provided with round convex shape tooth; The upper end of empennage is provided with round concave shape tooth;
The round convex shape tooth of the base plate below of supporting base and the round concave shape tooth of empennage top intercouple and lock; The top of supporting base is provided with cover plate; The below of cover plate is provided with two and hangs symmetrical elastic board chip.
Cover plate is fixedly connected with by Elastic buckle with supporting base; The cross section of described cover plate is " U " shape; The tapering of empennage is 0~20 degree; The bottom of empennage is triangular-arc, inner side hexagonal hollow out
The utility model compared with prior art has the following advantages:
1, the utility model is simple in structure, rationally novel in design, is easy to install.
2, the utility model, by supporting base, empennage being set, just becoming fixture by corresponding tapped hole composite joint, is easy to use and can distinguishes independent installation and fix.
3, the utility model is owing to adopting material modified manufacture, and by connecting, grip strength is larger, thereby has guaranteed communication leakage cable bearing capacity, and fixture is firm.
4, the utility model is owing to having adopted material modified manufacture, and product weight is light, and manufacturing process is simple, and cost is low, and using effect is remarkable, is convenient to promote the use of.
In sum, the utility model process structure is simple, and rationally novel in design, product weight is light, and grip strength is large, and reliable operation performance is high, and long service life is easier to adapt to urban track traffic operation and installs, and saves the installation time and improves work efficiency.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model tail structure schematic diagram (antapical view).
Fig. 3 is the spill toothing schematic diagram of the utility model empennage.
Fig. 4 is the structural representation of supporting base of the present utility model.
In figure: 1, base plate; 2, supporting base; 3, cover plate; 4, elastic board chip; 5, kayser hook; 6, round convex shape tooth; 7, round concave shape tooth; 8, empennage; 9, hexagonal member; 10, notch.
Embodiment
As shown in Figure 1, the utility model comprises base plate 1, supporting base 2, cover plate 3, elastic board chip 4, kayser hook 5, round convex shape tooth 6, round concave shape tooth 7, empennage 8, hexagonal member 9 and notch 10.
Base plate 1 is into a single integrated structure with supporting base 2, supporting base 2 below base plates 1 be provided with round convex shape tooth 6 below; The top of supporting base 2 is provided with cover plate 3.The below of cover plate 3 is provided with two and hangs symmetrical elastic board chip 4.The upper end of empennage 8 is provided with round concave shape tooth 7; Cover plate 3 is fixedly connected with by Elastic buckle with supporting base 2.The round convex shape tooth 6 of base plate 1 below of supporting base 2 intercouples and locks with the round concave shape tooth 7 of empennage 8 tops, makes thus supporting base with empennage, play the effect of anti-skidding.The cross section of cover plate is " U " shape.The inner side of empennage embeds hexagonal member 9.
The flexible plate 4 in below of cover plate 3, under cable installment state, elastic board chip 4 is opposite with the bottom surface of supporting base, and when cover plate and supporting base lock by snap device, elastic board chip 4 against and compress and be placed in the cable of accepting recess.
An important feature of the present utility model is the design of empennage, because supporting base need be connected and not only to have guaranteed that supporting base has enough rigidity but also increases stable intensity with empennage by bolt, therefore by a simple operations, just completed fixture installation, mounted cable is fixed on the basic components such as wall reliably, reached stable 3 stressed, here clamping effect is determined by fixture itself completely, installation quality can not be subject to the impact of the factors such as operator's assembly process, not only saves time but also laborsaving.
This use is novel has a unique cover plate 3, this cover plate 3 is accepted between recess and can be connected with supporting base by snap device at one, supporting base is connected and fixed by bolt and empennage, in such an embodiment, advantageously, the cross section of cover plate is " U " shape, and snap device is formed in the kayser hook on the both sides listrium of this U-shaped, make the kayser hook on cover plate cooperatively interact and be locked with the kayser hook that is formed in supporting base both sides, supporting base is connected 3 the stability under loading effects of having played with empennage.
On cover plate 3, be formed with the straight plate that elastic board chip can be designed to become symmetrically two suspentions, two elastic board chip projecting end sensing portions keep certain distance to be mutually symmetrical.On the cover board for cross section is local setting in the situation of stiffening rib on the plastics hin shell member of " U " shape, as long as elastic board chip can be realized predetermined clamping pressuring action.
Empennage unitary construction, the in the situation that of the strength deficiency of plastic own, embeds hexagonal member 9 by inner side, makes thus base plate and supporting base and even integral body can bear the larger load occurring on different direction, has guaranteed the strength and stability of fixture.
Empennage top has round concave shape tooth, can intercouple to be locked by supporting base boss profile of tooth to make thus supporting base play anti-skidding with empennage, and the tapering of empennage is 0~20 degree; The bottom of empennage is triangular-arc, inner side hexagonal hollow out, and supporting base is connected 3 the stability under loading effects of having played with empennage.
