Abstract
The utility model discloses a fixing tool for a horizontally-placed rectangular bus, and the tool comprises an upper cover, a bottom plate, and supporting columns disposed at two sides of a part between the upper cover and the bottom plate. Each supporting column is in a telescoping structure which consists of an external column in a hollow structure and an internal column, wherein the internal column is connected in the cavity of the external column and is in a hollow structure. The internal columns and the external columns are in threaded connection. The outer walls of the internal and external columns are respectively provided with a plurality of through holes along the axial direction. The supporting columns at two sides are connected with each other through hollow axis pins which are disposed in the corresponding through holes in a passing-through manner. The outer walls of the hollow axis pins are provided with a plurality of uniform heat-dissipation holes at intervals along the axial direction. Cylindrical projections are disposed between adjacent heat dissipation holes on the hollow axis pins. According to the utility model, the hollow axis pins pass through the supporting columns, and are provided with the heat-dissipation holes and the cylindrical projections, thereby reducing the contact areas of the bus with the axis pins, and facilitating heat dissipation.
Description
Technical field
The utility model belongs to distribution system technical field, relates in particular to a kind of rectangular bus bar and keeps flat fixing gold utensil.
Background technology
At present, in electrical power distribution system, the bus electric current passing through that is in operation changes, and heating situation also changes, so fixing on post insulator of multi-disc bus should be firm, can make again bus free-extension, in order to avoid make it be subject to extra stress.Although rectangular bus bar fixed hardware fittings of the prior art can play fixation, but could not effectively solve the heat that bus produces in the position of fixing gold utensil always, therefore, in order to realize effective heat radiation, all often to adjust by bus free-extension on fixing gold utensil, waste time and energy, the utmost point is science not.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of rectangular bus bar and keeps flat fixing gold utensil.
A kind of rectangular bus bar keeps flat fixing gold utensil, it comprises upper cover, base plate and be arranged on upper cover and base plate between the support column of both sides, described support column is Collapsible structure, its column jacket by hollow-core construction forms with the inner prop that is connected to the hollow-core construction in column jacket inner chamber, in, between column jacket, be threaded connection, in described, on the outer wall of column jacket, offer respectively vertically some through holes, between supported on both sides post, connect by the hollow bearing pin being located in through hole corresponding on supported on both sides post, on the outer wall of described hollow bearing pin, offer vertically the uniform louvre of some each intervals, between adjacent louvre on hollow bearing pin, be provided with columnar projections.
Owing to adopting technique scheme, the utlity model has following superiority:
1, be set to telescopic structure by support column, can be used in keeping flat of multi-disc bus fixing, and by the adjustment of support column height, be convenient to the heat radiation of bus;
2, the utility model by wearing hollow bearing pin between support column, and on hollow bearing pin, offer louvre and columnar projections, in the time that bus is placed on hollow bearing pin, bus supports by the projection on hollow bearing pin, reduce the contact area of bus and bearing pin, be conducive to heat radiation; By the louvre being connected with hollow bearing pin inner chamber is set, increase the circulation of bus ambient air in addition, further strengthened the heat radiation of bus.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-upper cover; 2-bus; 3-hollow bearing pin; 4-inner prop; 5-column jacket; 6-base plate; 7-louvre; 8-projection.
Embodiment
As shown in Figure 1, a kind of rectangular bus bar keeps flat fixing gold utensil, it comprises upper cover 1, base plate 6 and be arranged on upper cover and base plate between the support column of both sides, described support column is Collapsible structure, its column jacket 5 by hollow-core construction forms with the inner prop 4 that is connected to the hollow-core construction in column jacket inner chamber, in, between column jacket, be threaded connection, in described, on the outer wall of column jacket, offer respectively vertically some through holes, between supported on both sides post, connect by the hollow bearing pin 3 being located in through hole corresponding on supported on both sides post, on the outer wall of described hollow bearing pin 3, offer vertically the uniform louvre 7 of some each intervals, between adjacent louvre on hollow bearing pin 3, be provided with columnar projections 8.
The utility model by wearing hollow bearing pin 3 between support column, and on hollow bearing pin, offer louvre 7 and columnar projections, in the time that bus 2 is placed on hollow bearing pin 3, bus 2 supports by the projection on hollow bearing pin, reduce the contact area of bus and bearing pin, be conducive to heat radiation; By the louvre being connected with hollow bearing pin inner chamber is set, increase the circulation of bus ambient air in addition, further strengthened the heat radiation of bus.
