Description
Technical field
The utility model is related to a kind of Multifunctional bolts, belong to a kind of fastener.
Background technology
Fastener is most widely used fundamental parts, is to be fastenedly connected into two or more parts or component
The general name of used one kind machine components during one entirety.Fastener description is various, performance purposes each one, and standard
It is change, seriation, unitized strong.Wherein bolt is the most common type in fastener.Conventional bolt generally comprises
Head and the screw rod being connected under head, the bolt of this structure is simple in structure, and function is relatively also relatively simple, with
The continuous development of social economy, the bolt of traditional structure cannot satisfy the use demand.Therefore, it should which a kind of new skill is provided
Art scheme solves the above problems.
Invention content
The purpose of this utility model is to provide a kind of simple in structure, good Multifunctional bolt of using effect.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of Multifunctional bolt, including bolt head and screw rod, the lower plane center of the bolt head is equipped with plug-in unit, on screw rod
The position that surface corresponds to plug-in unit is provided with the slot being adapted with plug-in unit, and the junction of the bolt head and screw rod is surrounded by annular
Groove, waterproof shirt rim are located on the downside of the periphery of bolt head, and the upper plane of the screw rod is inclined surface, inclined surface and ring on screw rod
Connected in star matches, and one end that the screw rod is located at bolt head is equipped with symmetrical rotation stop piece, and the outer wall of the screw rod is equipped with recessed
Slot, the groove are located at screw rod with respect to the bolt head other end.
Further technical solution：
The plug-in unit and slot are "-" type.
The bolt head is hexagonal bolt head.
Due to the application of above-mentioned technical proposal, the utility model has the following advantages that compared with prior art：
1st, the bolt of the utility model due to being equipped with plug-in unit in the lower plane center of bolt head, is corresponded in screw rod upper surface
The position of plug-in unit is provided with the slot being adapted with plug-in unit, and plug-in unit and slot realization are detachably connected, and such structure design works as spiral shell
Bolt head occurs directly replacing bolt head when stripped thread or damage due to multi-pass operation, without screw rod to be replaced, favorably
In reduction use cost.
2nd, the bolt of the utility model, due to being equipped with waterproof shirt rim on the downside of the periphery of bolt head so that the utility model
Bolt can play effective water resistance.
3rd, the bolt of the utility model, due to being equipped with groove on the outer wall of screw rod, groove is arranged on the outer wall of shank of bolt,
Impurity can effectively be taken out of, increase the service life of bolt.
4th, the junction of the bolt of the utility model, bolt head and screw rod is surrounded by annular groove, the upper plane of screw rod
For inclined surface, the inclined surface on screw rod is matched with annular groove, and such structure design may insure bolt head and screw rod
It is in close contact, ensures the stability of installation.
Description of the drawings
It is attached that FIG. 1 is a schematic structural view of the utility model.
In the figures above：1st, bolt head, 2, screw rod, 3, groove, 4, plug-in unit, 5, slot, 6, annular groove, 7, water-proof skirt
Side, 8, rotation stop piece, 9, inclined surface.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments：
Embodiment one：
As shown in Figure 1, a kind of Multifunctional bolt of the utility model, including bolt head 1 and screw rod 2, under the bolt head 1
Plane central is equipped with plug-in unit 4, and the position that 2 upper surface of screw rod corresponds to plug-in unit is provided with the slot 5 being adapted with plug-in unit 4, the bolt
First 1 is surrounded by annular groove 6 with the junction of screw rod 2, and waterproof shirt rim 7 is located on the downside of the periphery of bolt head 1, the screw rod 2
Upper plane for inclined surface 9, the inclined surface 9 on screw rod 2 is matched with annular groove 6, and the screw rod 2 is located at the one of bolt head 1
End is equipped with symmetrical rotation stop piece 8, and the outer wall of the screw rod 2 is equipped with groove 3, and the groove 3 is located at screw rod 2 with respect to bolt head 1
The other end.
Preferably, as second embodiment of the utility model, the present embodiment is the further restriction to embodiment one,
The plug-in unit 4 and slot 5 are "-" type.
Preferably, as the third embodiment of the utility model, the present embodiment is also the further limit to embodiment one
Fixed, the bolt head 1 is hexagonal bolt head.
The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art
For personnel, under the premise of principle described in the utility model is not departed from, several improvement or replacement can also be made, these improvement
Or it replaces and also should be regarded as the scope of protection of the utility model.
