Description
Technical field
The utility model relates to machanical fastener technical fields, more particularly to a kind of self-tightening type check bolt.
Background technique
Bolt is more commonly used fastener, though the form that the fixation of certain structures part is fixed using bolt, but
It is also required to the structure convenient for fast assembling-disassembling, though existing bolt arrangement has the structure of fast assembling-disassembling to design, usual structure compares
Complexity, cost are relatively high.
Utility model content
The utility model aim is to provide for a kind of self-tightening type check bolt, and structure is simple, low cost, and convenient for adjusting
Its whole position, can fast assembling-disassembling, and be not easy to loosen.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
The utility model provides a kind of self-tightening type check bolt, including bolt body, and the bolt body is integrally in the form of a column,
There is prismatic protrusion in its two sides, the bolt body and the prismatic protrusion constitute section into the band circular bolt body of ear,
The bolt through-hole to match with the cross sectional shape of the bolt body is provided in workpiece surface, wherein the top of the bolt body
With end cap, bottom end, which passes through the bolt through-hole and has in the bottom end of the bolt body to the bolt body side, to be extended
Claw out is socketed with spring outside the bolt body, and the spring is limited between the end cap and workpiece, for pushing up
Play the bolt body card on the workpiece.
Further, there are two prismatic protrusions, two prismatic protrusions are symmetrical with the spiral shell in the bolt body
The bottom end of the bolt body is arranged in the two sides for being axially disposed within the bolt body of bolt main body, the claw.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
The self-tightening type check bolt of the utility model, is carried out by claw set by bolt body bottom by bolt body
Limit is in bolt through-hole, so that bolt body will not fall off, it is in conjunction with the reversed effect of shoring of spring, bolt body is stuck
In bolt through-hole, card slot corresponding with bolt body and claw only need to be opened up on another workpiece when in use, is then
It can realize being fixedly connected between two workpiece by this self-tightening type check bolt, convenient for disassembly and assembly and this bolt arrangement is simple,
Low cost, convenient for promoting.
Detailed description of the invention
Some specific realities of the utility model are described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter
Apply example.Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing:
Fig. 1 is according to the structural schematic diagram of the self-tightening type check bolt of the utility model one embodiment, at this point, bolt sheet
Body is in the state under being pressed.
Wherein, the reference numerals are as follows:
1, bolt body；2, end cap；3, claw；4, prismatic protrusion；5, spring；6, the workpiece of fixing bolt.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Present embodiment describes a kind of self-tightening type check bolts, as shown in Figure 1 comprising bolt body 1, the bolt master
Body 1 is whole to be in the form of a column, and has prismatic protrusion 4 in its two sides, the bolt body 1 constitutes section into band with the prismatic protrusion 4
The circular bolt body of ear is provided with the bolt through-hole to match with the cross sectional shape of the bolt body on 6 surface of workpiece, wherein
The top of the bolt body have end cap 2, bottom end pass through the bolt through-hole and the bottom end of the bolt body have to
The claw 3 that the bolt body side is extended, is socketed with spring 5 outside the bolt body 1, and the spring 5 is limited at
Between the end cap 2 and workpiece 6, it is stuck in the workpiece 6 for jacking up the bolt body, will not be loosened.
Further, there are two prismatic protrusions 4, two prismatic protrusions 4 are symmetrical with described in the bolt body
The bottom end of the bolt body 1 is arranged in the two sides for being axially disposed within the bolt body 1 of bolt body 1, the claw 3.
In summary, the self-tightening type check bolt of the present embodiment, by claw 3 set by bolt body bottom carry out by
Bolt body limits in bolt through-hole, so that bolt body will not fall off, in conjunction with the reversed effect of shoring of spring 5, by spiral shell
Bolt ontology is stuck in bolt through-hole, need to only open up on another workpiece when in use corresponding with bolt body 1 and claw 3
Then card slot can pass through being fixedly connected between this self-tightening type check bolt two workpiece of realization, convenient for disassembly and assembly and this spiral shell
Stud structure is simple, low cost, convenient for promoting.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
