Abstract
The utility model relates to a bolt, in particular to T type grounded bolt. Its structure includes connectivity platform, connectivity platform below welding hex bolts, connectivity platform's lower surface limit portion be provided with barb portion. The utility model discloses optimize the improvement to traditional ystem installation, make to reach zonulae occludens through this structure of barb between each installing component, saved traditional added metal earthing device, simplified installation steps, saved installation cost.
Description
Technical field
The utility model relates to a kind of bolt, particularly the T-shaped earth stud of one.
Background technique
Often with bolts in traditional connection bracket, the assembling set of such as photovoltaic system, this bolt connects it and generally has following deficiency: 1, linkage structure is firm not, easily gets loose between bolt and assembling set.2, have between bolt with assembling set and be connected gap, its ground connection poor performance.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of T-shaped earth stud, and not only can to realize between bolt with link firm is connected for it, and combine closely between bolt and link, and ground connection performance is better.
The technological scheme that the utility model adopts is as follows:
A kind of T-shaped earth stud, comprise connecting platform, weld hex head bolt below described connecting platform, the lower surface edge of described connecting platform is provided with hangnail portion.
Hangnail portion comprises sharp-pointed portion of thrusting and joint, and described joint two ends are arranged described thrusts portion.
Hangnail portion is 2 places, 2 described hangnail portions of place with the axle center of hex head bolt for the center of circle is symmetrical.
The beneficial effect that the technological scheme that the utility model provides is brought is:
By increasing and change the construction profile of bolt on the plain bolt basis that earth stud of the present utility model uses in original photovoltaic system is installed, in use by external force that thread produces, the barbed portion of earth stud is directly thrust other assemblys of photovoltaic system, reach reliable electrical connection, simplify installation procedure under the prerequisite that the electrical grounding installed photovoltaic system in satisfied country requires, save installation cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural front view of a kind of T-shaped earth stud of the present utility model;
Fig. 2 is the structure worm's eye view of a kind of T-shaped earth stud of the present utility model;
Fig. 3 is the A place part-structure enlarged diagram of Fig. 2.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment one
A kind of T-shaped earth stud, comprise connecting platform 1, weld hex head bolt 2 below described connecting platform 1, the lower surface edge of described connecting platform 1 is provided with hangnail portion 3.
As shown in Figure 3, the hangnail portion 3 of the present embodiment comprises sharp-pointed portion of thrusting 31 and joint 32, and described joint 32 two ends arrange described portion of thrusting 31.
Hangnail portion 3 is 2 places, 2 described hangnail portions of place with the axle center of hex head bolt for the center of circle is symmetrical.
After earth stud and link are combined closely, the hexagonal position of earth stud self is turned with the inner hexagon spanner of correspondence, further generation rotating force, makes earth stud hangnail portion 3 thrust link completely, reaches photovoltaic system and installs Chinese target related electric connection request.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
