Abstract
A kind of self-lubricating bolt of the utility model, comprises bolt body, T font core bar, spring and oil bag; Bolt body comprises the bolt head of upside and the bolt shank of downside; Bolt head be axially provided with blind hole; T font core bar is coordinated in blind hole; Spring is provided with between T font core bar and the diapire of blind hole; And be provided with gap ξ between the bottom of T font core bar and the diapire of blind hole; The diapire of the blind hole on the downside of T font core bar sets firmly oil bag; The diapire of the described blind hole below oil bag is provided with oil guiding hole; Oil guiding hole leads to the surface of bolt shank; T font core bar is also provided with the sharp protrusion for puncturing oil bag; Oil bag is built with lubricant oil.By the way, provide a kind of self-lubricating bolt, the mode that can manually press adds lubricant oil automatically in the process of bolt tightening, thus increases work efficiency; And protect part itself, avoid damage.
Description
Technical field
The utility model relates to hardware fitting manufacture field, particularly relates to a kind of self-lubricating bolt.
Background technique
bolt is the important hardware fitting being widely used in mechanical field, and it, is needed and nut screw connection, for being fastenedly connected two parts with through hole with an externally threaded cylindrical body class fastening piece dimerous by head and screw rod.The relatively large bolt of some specifications can be used in the machinery that some are large-scale, such as, in large ship manufacture process, usually can use some homemade non-standard large-sized bolt and nuts.Bolt needs instillation lubricant oil to reduce the resistance of screw-thread fit in use, thus the power needed for pretension bolt.The backwardness that artificial addition manner compares, and cumbersome, be unfavorable for increasing work efficiency.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of self-lubricating bolt, and it is reasonable in design, and structure is simple, solves bolt adds lubricant oil problem when tightening.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is to provide a kind of self-lubricating bolt, comprises bolt body, T font core bar, spring and oil bag; Described bolt body comprises the bolt head of upside and the bolt shank of downside; Described bolt head be axially provided with blind hole; Described T font core bar is coordinated in described blind hole; Described spring is provided with between described T font core bar and the diapire of described blind hole; And be provided with gap ξ between the bottom of described T font core bar and the diapire of described blind hole; The diapire of the described blind hole on the downside of described T font core bar sets firmly described oil bag; The diapire of the described blind hole below described oil bag is provided with oil guiding hole; Described oil guiding hole leads to the surface of described bolt shank; Described T font core bar is also provided with the sharp protrusion for puncturing described oil bag; Described oil bag is built with lubricant oil.
Preferably, the ingress described bolt head being positioned at described blind hole is provided with for the spacing projection of T font core bar.
The beneficial effects of the utility model are: provide a kind of self-lubricating bolt, and the mode that can manually press adds lubricant oil automatically in the process of bolt tightening, thus increases work efficiency; And protect part itself, avoid damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of self-lubricating bolt of the utility model;
Fig. 2 is the partial enlarged view of Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, bolt body; 2, T font core bar; 3, spring; 4, oil bag; 5, oil guiding hole; 6, sharp protrusion; 7, projection.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to attached Fig. 1 and 2, the utility model is embodiment comprise:
A kind of self-lubricating bolt, comprises bolt body 1, T font core bar 2, spring 3 and oil bag 4; Described bolt body 1 comprises the bolt head of upside and the bolt shank of downside; Described bolt head be axially provided with blind hole; Described T font core bar 2 is coordinated in described blind hole; Described spring 3 is provided with between described T font core bar 2 and the diapire of described blind hole; And be provided with gap ξ between the bottom of described T font core bar 2 and the diapire of described blind hole; The diapire of the described blind hole on the downside of described T font core bar 2 sets firmly described oil bag 4; The diapire of the described blind hole below described oil bag 4 is provided with oil guiding hole 5; Described oil guiding hole 5 leads to the surface of described bolt shank; Described T font core bar 2 is also provided with the sharp protrusion 6 for puncturing described oil bag 4.The ingress that described bolt head is positioned at described blind hole is provided with for the spacing projection 7 of T font core bar 2.
During use, by pressing the T font core bar at bolt head top, T font core bar is to pressing down, and the oil bag below it punctures by the sharp protrusion of T font core bar, and lubricant oil just can flow to the surface of bolt shank by the oil guiding hole on the downside of oil bag, thus plays the effect of lubrication.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
