Abstract
The utility model discloses a combined bolt, which comprises a normal bolt and a bolt bushing, wherein the bolt bushing is sleeved on a screw of the normal bolt; a limiting ring which extends inwards is formed at an opening of the bolt bushing; and the screw is provided with a bump. According to the combined bolt, the problem of inconvenience in mounting and carrying of the combined bolt in the prior art is solved; and by arranging one limiting ring on the bolt bushing and the bump on the screw, the bolt bushing can move relative to the bolt but cannot be separated from the bolt to guarantee integral connection of the bolt bushing and the bolt and facilitate mounting and carrying.
Description
Technical field
The utility model has related to a kind of assembling bolt, belongs to the link technical field.
Background technique
Bolt mainly is to play the effect that connects two objects, at present, need to all connect with plain bolt with bolted object major part, can play simple fastening effect, but the head of plain bolt is less with the surface of contact that is connected object, it is larger to cause surface of contact to go out pressure, damage easily fastening, thereby usually fill a lining at bolt coat and become assembling bolt, to increase surface of contact, but existing assembling bolt is separation structure normally, makes installation, carries and all brought a lot of inconvenience.
The model utility content
Technical problem to be solved in the utility model provides a kind of assembling bolt, can not only increase the surface of contact of joint, and plain bolt and bolt bush are realized integrated design, is easy to carry and installs.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of assembling bolt comprises plain bolt and bolt bush, and described bolt bush is sleeved on the screw rod of described plain bolt, and the opening of described bolt bush is provided with a limited ring that extends internally, and described screw rod is provided with projection.
Aforesaid a kind of assembling bolt is characterized in that: the bottom of described screw rod is provided with the inclined-plane with respect to described screw rod inclined bottom surface.
The beneficial effects of the utility model are: by a limited ring is set at bolt bush, and at screw rod projection is set, bolt bush can be moved relative to bolt, but can not separate with it, guarantee that both one connect, be convenient to installation and carry.
Description of drawings
Fig. 1 is the sectional drawing of a kind of assembling bolt of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of assembling bolt comprises plain bolt 1 and bolt bush 3, and described bolt bush 3 is sleeved on the screw rod 2 of described plain bolt 1, and the opening of described bolt bush 3 is provided with a limited ring that extends internally 4, and described screw rod 2 is provided with projection 5.
By a limited ring 4 is set at bolt bush 3, and at screw rod 2 projection 5 is set, bolt bush 3 can be moved relative to bolt 2, but can not separate with it, guarantee that both one connect, when mounted, carry out fastening after need not to install to bolt bush 3 covers on the screw rod 2 again, saved the together operation of suit, made installation more convenient.
The bottom of screw rod 2 is provided with the inclined-plane 6 with respect to described screw rod 2 inclined bottom surfaces, reduces by the bottom section with screw rod 2, is convenient to screw rod and is inserted in the object of being with connection.
In sum, a kind of assembling bolt provided by the utility model can not only increase the surface of contact of joint, and plain bolt and bolt bush are realized integrated design, is easy to carry and installs.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
