Abstract
The utility model relates to a bolt capable of being overlaid. The bolt comprises a large-diameter bolt and a small-diameter bolt which is arranged under the large-diameter bolt, the outer surface of the large-diameter bolt and the outer surface of the small-diameter bolt are all provided with threads, and an inner thread hole is formed in the middle of the top of the large-diameter bolt, the top of the large-diameter bolt is provided with a line-shaped groove, the bottom of the middle of the inner thread hole is provided with a cross groove, and the inner thread hole and the small-diameter bolt can be matched with each other. The bolt capable of being overlaid is simple in structure, can enable the connection length of the bolt to be allocated freely according to the length of a connection hole, improves installation efficiency, enlarges using ranges, and is suitable for being popularized.
Description
Technical field
The utility model relates to a kind of bolt, relates in particular to a kind of stackable formula bolt.
Background technique
Bolt all is widely applied in present various fields as a kind of fastening means.Because the required bolt style in various fields is different, therefore, the kind of bolt is also very various on the market now.
Because screw is the most a kind of fastening means mainly, so the length of screw has a direct impact connecting effect; Many staff are inadequate owing to screw length when connection fittings, therefore need to again replace screw, also cause working efficiency to reduce, even affect the usability of later stage product after after installing, reduction connects effect greatly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good connecting effect can not be subjected to the stackable formula bolt of the long restriction of attachment hole.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: this stackable formula bolt, comprise the particle size bolt and be arranged on thin footpath bolt under the particle size bolt, affiliated particle size bolt and thin footpath bolt outer surface are provided with screw thread, particle size bolt crown center position is provided with interior threaded hole, and affiliated particle size bolt top is provided with straight groove.
In order conveniently to screw, further, described interior threaded hole central bottom is provided with cross recess.
For convenient stack, more further, described interior threaded hole can be worked in coordination with thin footpath bolt.
Compared with prior art, usefulness of the present utility model is: this stackable formula bolt arrangement is simple, can improve installation efficiency according to the attachment hole personal attendant configuration bolt connecting length of anticipating, and also enlarges using scope, and with popularization.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the stackable formula bolt arrangement of the utility model schematic representation;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1, particle size bolt; 2, straight groove; 3, thin directly bolt; 4, interior threaded hole; 5, cross recess.
Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
Fig. 1, a kind of stackable formula bolt shown in Figure 2, comprise particle size bolt 1 and be arranged on thin footpath bolt 3 under the particle size bolt 1, affiliated particle size bolt 1 and thin footpath bolt 3 outer surfaces are provided with screw thread, particle size bolt 1 crown center position is provided with interior threaded hole 4, and affiliated particle size bolt 1 top is provided with straight groove 2; Described interior threaded hole 4 central bottom are provided with cross recess 5; And described interior threaded hole 4 can be worked in coordination with thin footpath bolt 3.
Its specific works mode is as follows, according to the length of attachment hole bolt is set, and the thin footpath bolt 3 of the first bolt bottom is screwed in second bolt particle size bolt 1 top interior threaded hole 4, increases the length of bolt.
This stackable formula bolt arrangement is simple, can improve installation efficiency according to the attachment hole personal attendant configuration bolt connecting length of anticipating, and also enlarges using scope, and with popularization.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
