Abstract
The invention discloses a clamp for a leaky coaxial cable for railway communication. The clamp for the leaky coaxial cable for railway communication comprises a base plate and a supporting seat which form an integral structure. Round convex teeth are arranged under the base plate under the supporting seat. The upper end of a tail fin is provided with round concave teeth. The round convex teeth under the base plate of the support seat and the round concave teeth above the tail fin are coupled and locked. A cover plate is arranged above the supporting seat. Two suspended and symmetrically-distributed elastic plate sheets are arranged under the cover plate. The cover plate and the supporting seat are fixedly connected through elastic fasteners. A cross section of the cover plate is U-shaped, and the taper of the tail fin is 0-20 degrees. The bottom end of the tail fin is in a shape of a triangular arc, and the inner side of the tail fin is hexagonally hollow. The clamp for the leaky coaxial cable for railway communication is simple in process structure, novel and reasonable in design, light in product weight, large in clamping strength, high in working reliability performance, long in service life and easily adapts to urban rail transit operation installation, the installation time is saved, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of fixture, relate in particular to a kind of railway communication leakage coaxial cable fixture.
Background technique
Along with the urban rail transit in China technology is constantly improved development, the train speed per hour grade improves constantly, standard code according to the railway communication leakage coaxial cable fixture of " People's Republic of China's railroad industry standard " 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 the cable installation situation, for in the urban track traffic tunnel, no longer adapting to modernized railway communication needs along traditional sling and jig of wall fixed communication leakage cable, more can't meet the standard of railway communication leakage coaxial cable suspender, the Lou cable of how communicating by letter is fixed on tunnel and 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 subjected to train travel to produce the purpose that the various factors such as air-flow and vibrations can't reach fixed communication leakage cable, badly influences train traffic safety and railway communication guarantee.Therefore need design a kind of in the urban track traffic tunnel along the wall fixation and the fixture that is easy to install and super tough and tension against shock need be arranged and have enough grip strength.
Summary of the invention
In order to solve the existing deficiency of above-mentioned technology, the invention provides a kind of railway communication leakage coaxial cable fixture.
In order to solve above technical problem, the technical solution used in the present invention 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 the round convex shape tooth; The upper end of empennage is provided with the round concave shape tooth;
The mutual coupling of round concave shape tooth of the round convex shape tooth of the floor below of supporting base and empennage top locking; 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, inboard hexagonal hollow out
The present invention compared with prior art has the following advantages:
1, the present invention is simple in structure, rationally novel in design, is easy to install.
2, the present invention, by supporting base, empennage being set, just becoming fixture by corresponding tapped hole composite joint, is easy to use and can distinguishes independent the installation and fix.
3, the present invention 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 present invention 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, process structure of the present invention is simple, and rationally novel in design, product weight is light, and grip strength is large, and the reliable operation performance is high, and long service life is easier to adapt to the urban track traffic operation and installs, and saves the installation time and improves work efficiency.

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 present invention includes 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.
The flexible plate 4 in the below of cover plate 3, under the cable installment state, elastic board chip 4 is opposite with the bottom surface of supporting base, and when cover plate and supporting base locks by snap device, elastic board chip 4 against and compression be placed in the cable of accepting recess.
An important feature of the present invention is the design of empennage, because supporting base need connect 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 the 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 fully, 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 with supporting base, be connected 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 the 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 sections keep certain distance to be mutually symmetrical.On the cover board for cross section is local the 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 the clamping pressuring action of being scheduled to.
The empennage unitary construction, in the situation that the strength deficiency of plastic own embeds hexagonal member 9 by inboard, make base plate and supporting base and even integral body can bear the larger load occurred on different direction thus, guaranteed the strength and stability of fixture.
The empennage top has the round concave shape tooth, can be locked and make thus supporting base play anti-skidding with empennage by the mutual coupling of supporting base boss profile of tooth, and the tapering of empennage is 0～20 degree; The bottom of empennage is triangular-arc, inboard hexagonal hollow out, and supporting base is connected 3 the stability under loading effects of having played with empennage.
