Description
Technical field
The utility model belongs to component of machine technical field, and in particular to a kind of welded type screw retention set.
Background technology
Threaded connection is a kind of most widely used machine components connected mode, and it detachably connects between belonging to machine components
Static connection mode in connecing.But bolt or nut loosening, which easily occurs, in use in it under some specific operating modes causes
Joint failure.The very high and special occasions of use environment very severe in some reliability requirements, such as locomotive, subway
Etc., the generation of major accident is easily lead in the event of threaded connection failure.Iing is required that it is high that high reliability exists again
During the operating mode of severity vibration or high temperature difference, how threaded connection solves the problems, such as that its thread looseness becomes problem.
At present, it is many to solve the measure of locking thread, for example with spring washer, dress split pin and beats screw thread fastening glue
Deng.But they are not that poor reliability is exactly that cost is high or inconvenient for operation.Due to height is generally used in highly reliable application scenario
The alloy bolt of intensity, to bolt directly with it is also infeasible by fastener welding.Therefore, need badly a kind of reliability of exploitation it is high, into
This welded type screw retention set low, applied widely, easy to use.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcomings of to mention in background above technology and defect, is carried
For a kind of reliability is high, cost is low, wide adaptation range, welded type screw retention set easy to use.
In order to solve the above technical problems, the utility model proposes technical scheme be：
A kind of welded type screw retention set, including the loose-proof sleeve body for being welded with connected component, the loose-proof sleeve
There is the inner chamber for being used for being socketed bolt head and limit bolt head rotation on body.After bolt fastening in place, this is prevented
Pine is socketed on bolt head, and imposes spot welding with connected component in the surrounding multiple spot of loose-proof sleeve, it is possible to is reached very
Reliable anti-loosing effect.If necessary to dismantle the bolt, the welded type screw retention need to only be covered to institute's welding point engraving tool and gone.
Preferably, the inner chamber is a through hole being opened on the loose-proof sleeve body.Bolt is conveniently observed using through hole
Connection, and material can be saved.
Preferably, the inner chamber is one to be opened in blind hole on the loose-proof sleeve body, the depth of the blind hole be more than or
Equal to the height of the bolt head.Protective action can be played to bolt using blind hole.
Preferably, the shape of the inner chamber is consistent with the circumferential profile shape of the bolt head, and the size of inner chamber is equal to
Or slightly larger than bolt head.
Preferably, the loose-proof sleeve body is identical with the material of the connected component.In this way, loose-proof sleeve can be made and connected
Weld more firm between relay part, avoid that sealing-off occurs under vibration.
Preferably, the periphery of the loose-proof sleeve body is circular or square.
Compared with prior art, the utility model has the advantage of：By setting loose-proof sleeve body, on the loose-proof sleeve body
With inner chamber, after bolt is fastened on connected component, this loose-proof sleeve is enclosed on the head of bolt, and in loose-proof sleeve four
Zhou Duodian imposes spot welding with connected component, it is possible to reaches very reliable anti-loosing effect.The welded type screw retention noose
Structure is simple, reliability is high, cost is low, wide adaptation range, easy to use.

Embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, meticulously describes, but the scope of protection of the utility model is not limited to embodiment in detail below.
It should be strongly noted that when a certain element, to be described as " be fixed on, be fixed in, be connected to or be communicated in " another
When on element, it can be directly fixed, affixed, connection or connect on another element or by connecting among other
Fitting is indirectly fixed, affixed, connection or connection are on another element.
Unless otherwise defined, the implication that all technical terms used hereinafter are generally understood that with those skilled in the art
It is identical.Technical term used herein is intended merely to describe the purpose of specific embodiment, is not intended to and limits this practicality
New protection domain.
Embodiment 1：
As shown in Figure 1, Figure 2 and Figure 3, a kind of embodiment of the utility model welded type screw retention set.The welded type spiral shell
Bolt loose-proof sleeve includes a loose-proof sleeve body 1 being used for connected component welding, along loose-proof sleeve body on the loose-proof sleeve body 1
1 axial direction offers a through hole (i.e. inner chamber 101).Using through hole as inner chamber 101, the convenient connection feelings for observing bolt
Condition, and the thickness of loose-proof sleeve can be less than the height of bolt head 2, save material.The shape of inner chamber 101 can be triangle,
The various shapes such as square, rhombus, rotated wherein as long as bolt head 2 can be limited, but not should be circular (not limiting
The rotation of bolt head 2 processed).It is preferred that the shape of inner chamber 101 is consistent with the circumferential profile shape of bolt head 2.The inner chamber 101
Size is equal to or slightly greater than the size of bolt head 2, can not be excessive, is defined by the rotation that can effectively limit bolt head 2.Should
Welded type screw retention set preferably using material same or like with connected component and with solderability, can so make locking
Welded between set and connected component more firmly, avoid loose-proof sleeve sealing-off under vibration.
In use, welded type screw retention set is socketed on bolt head 2 after tightening, then in screw retention set
Surrounding multiple spot and connected component impose spot welding, it is possible to play reliable anti-loosing effect, fixed and prevented by loose-proof sleeve
There is the situation of loose or dislocation in vibration environment in bolt, ensures the reliability service of product.If the threaded connection needs to dismantle,
Loose-proof sleeve institute welding point can be carved and gone.Welded type screw retention nested structure is simple, cost is low for this, safe and reliable, user
Just, it is highly suitable for being not required to the threaded connection application scenario dismantled or need to only dismantled once in a while.
Embodiment 2：
A kind of as shown in figure 4, embodiment of the utility model welded type screw retention set.The welded type screw retention cover with
Embodiment 1 is different compared to the concrete structure of simply inner chamber 101.In the present embodiment, inner chamber 101 is one along loose-proof sleeve body 1
The blind hole axially opened up, the depth of the blind hole are more than or equal to the height of bolt head 2.If bolt head 2 is long-term directly sudden and violent
Expose outside, easily cause bolt corrosion, covered on bolt head 2 in blind hole by the welded type screw retention set of the present embodiment,
The protective action to bolt can also be played while bolt looseness is prevented, slow down the corrosion of bolt to a certain extent.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
