Abstract
The utility model discloses a special-shaped hole mechanism for cable installation of rail transit vehicle-mounted equipment, which consists of a square hole and four round holes; the four round holes are uniformly distributed on the periphery of the square hole, and each round hole corresponds to one edge of the square hole. The utility model discloses simple structure, simple to operate, it is good to take precautions against earthquakes, anti falling performance, and is with low costs, and later maintenance is convenient, and application scope is wide, long service life.
Description
Technical Field
The utility model belongs to the technical field of the communication mobile unit installation, concretely relates to dysmorphism hole mechanism of track traffic mobile unit cable installation.
Background
At present, most of vehicle-mounted equipment of a rail transit communication system adopts a traditional cable to install a circular hole; the traditional vehicle-mounted equipment mounting hole is in circular four-point fixed mounting, and the requirements on installation, processing and process of the butting plug-in are low. Because the vehicle-mounted equipment is in the triaxial vibration working state for a long time, higher requirements are provided for the reliability of the cable connector of the vehicle-mounted equipment. The traditional equipment mounting hole installation cable requires highly, and the construction is wasted time and energy. The following problems are generally present:
1. the cable installation of the existing communication vehicle-mounted equipment does not consider the working state that a connector of the cable is in vibration for a long time after the equipment;
2. most communication vehicle-mounted equipment adopts a traditional cable installation circular hole, the traditional cable installation circular hole is in a vibration working state for a long time, and due to a special working state, a cable is easy to loosen or break, so that potential safety hazards exist;
3. maintenance in the later stage of the equipment is not standard, and due to the reasons of rough construction, subsequent equipment increase adjustment and the like, the equipment cable is plugged or loosened, the original cable hole is deformed or damaged, and subsequent construction, installation and maintenance are not facilitated.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art, the utility model aims at providing a simple structure, use, simple to operate, easy operation, it is good to take precautions against earthquakes, anti falling performance, and is with low costs, and later maintenance is convenient, and application scope is wide, long service life, the heterotypic hole mechanism of the mobile unit cable installation that has safe and reliable effect.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model discloses a special-shaped hole mechanism for cable installation of rail transit vehicle-mounted equipment, which comprises a square hole and four round holes; the four round holes are uniformly distributed on the periphery of the square hole, and each round hole corresponds to one edge of the square hole.
Preferably, the square hole is subjected to deburring and polishing treatment.
Preferably, the square hole has a width of 24mm and a thickness of 1.5 mm.
Preferably, the diameter of the circular holes is 3.2mm, and the hole distance between the two circular holes is 20 mm.
The utility model has the advantages that:
the utility model discloses a dysmorphism hole mechanism has characteristics such as safe and reliable, elegant appearance, simple to operate are swift, wide application in fields such as communication, electric, construction work.
Drawings
Fig. 1 is a structural diagram of the present invention.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Referring to fig. 1, the special-shaped hole mechanism for cable installation of the rail transit vehicle-mounted device of the present invention is composed of a square hole and four round holes; the four round holes are uniformly distributed on the periphery of the square hole, and each round hole corresponds to one edge of the square hole.
And carrying out deburring and polishing treatment on the square hole.
The width of the square hole is 24mm, and the thickness of the square hole is 1.5 mm.
The diameter of the round hole is 3.2mm, and the hole interval between the two round holes is 20 mm.
The utility model discloses the concrete application way is many, and the above-mentioned only is the preferred embodiment of the utility model, should point out, to ordinary skilled person in this technical field, under the prerequisite that does not deviate from the utility model discloses the principle, can also make a plurality of improvements, and these improvements also should be regarded as the utility model discloses a scope of protection.
