Abstract
The utility model discloses a bolt which is not easy to rust and corrode and good in sealing performance. The bolt comprises a bolt head, a naked bolt column and a thread bolt, wherein the bolt head, the naked bolt column and the thread bolt are sequentially arranged, a ceramic sleeve is arranged on the naked bolt column, and a rubber ring is arranged between the ceramic sleeve and the naked bolt. The ceramic sleeve is arranged on the naked bolt column of the bolt, the rubber ring plays a role of expansion, the ceramic sleeve is tightly attached to an installation hole, and the aim that the sealing performance is increased is achieved. Simultaneously, the bolt is effectively prevented from being corroded by moist air to generate rusted phenomenon. The bolt with the ceramic sleeve is simple in structure and has practical value.
Description
Technical field
The utility model relates to a kind of bolt with ceramic jacket.
Background technique
In known technical field, bolt is the fastening piece between a kind of common component, in industrial production, be widely used, in actual use, bolt because and have the gap between the mounting hole, there is defective in sealability, the simultaneously bolt corrosion that gets rusty easily at the position of being combined with mounting hole after installation, the dead phenomenon of rust occurs, and is unfavorable for follow-up maintenance replacing.
The model utility content
The technical problems to be solved in the utility model is: a kind of bolt that is difficult for corrosion and good seal performance is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bolt with ceramic jacket, comprise the spiral shell head, light double-screw bolt and the threaded stud that set gradually, be provided with ceramic jacket at described smooth double-screw bolt, between described ceramic jacket and light double-screw bolt, be provided with rubber ring.
The beneficial effects of the utility model are: the utility model partly arranges ceramic jacket by the light double-screw bolt at bolt, and the expansion by rubber ring, so that ceramic jacket and mounting hole are close to, thereby reach the purpose that increases its sealability, simultaneously prevented effectively that also bolt from being corroded by malaria, and the dead phenomenon of rust occurs, this programme is simple in structure, has use value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. spiral shell head, 2. smooth double-screw bolt, 3. threaded stud, 4. ceramic jacket, 5. rubber ring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of bolt with ceramic jacket of the utility model as shown in Figure 1 comprises the spiral shell head 1, light double-screw bolt 2 and the threaded stud 3 that set gradually, is provided with ceramic jacket 4 at described smooth double-screw bolt 2, is provided with rubber ring 5 between described ceramic jacket 4 and light double-screw bolt 2.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
