Abstract
The utility model belongs to the field of workpiece fastening and particularly relates to an anti-release sleeve for a nut. The anti-release sleeve for the nut comprises a handle, a sleeve rod and a nut contact mechanism, wherein one end of the sleeve rod is connected with the handle, and the nut contact mechanism is positioned in the other end of the sleeve rod. The anti-release sleeve for the nut is characterized by further comprising a clamping mechanism and a compressing mechanism which are positioned in the other end of the sleeve rod, wherein the clamping mechanism is an elastic piece arranged in a gap in the sleeve rod, and the compressing mechanism comprises a spring and an ejector pin connected with the spring and positioned close to the nut contact mechanism. The anti-release sleeve for the nut is simple in structure. By means of the clamping mechanism, the nut and a gasket are clamped tightly, and the nut cannot break away from the inside of the sleeve rod. By means of the compressing mechanism, operators can fasten the nut conveniently, and work efficiency is increased.
Description
Technical field
The utility model relates to and belongs to the fastening field of workpiece, particularly relates to a kind of nut anti-falling sleeve.
Background technology
At present, workpiece is carried out when fastening, general what adopt is screw bolt and nut.Nut is exactly nut, is used for playing the role of fastening together with bolt or screw rod are screwed in, and the operation principle of nut is to adopt the frictional force between nuts and bolt to carry out self-locking.But the reliability of this self-locking will reduce in dynamic loading.In some important occasions, we will take some locking measures, ensure the reliability of nut check.When fastening to workpiece, first operating personnel penetrate workpiece bolt, then pad are inserted in to bolt, then nut is put into bolt, finally with spanner or inner hexagon spanner rotating nut, thereby by fastening nuts.But less when operating space, or while using the less nut of size, manual operations is difficult for, and easily drops out from workpiece.
Chinese patent CN202668444U has announced a kind of fastening nuts loop bar, is made up of tommy bar and block set; Cylinder table shape block set one side is with one section of hexagonal prism tommy bar, and another side is provided with a hex nut groove.When clamp nut, the hex nut groove of cover stem casing seat is enclosed within on nut, then blocks the rotation of hexagonal prism tommy bar with box spanner and fastening nuts can be put in place.This utility model can be fast by fastening nuts, and increases fastening force, avoids cutting edge loosening.But during with this fastening nuts loop bar clamp nut, nut easily departs from from loop bar.
Utility model content
The purpose of this utility model is: overcomes the defect that prior art exists, proposes a kind of nut anti-falling sleeve, and simple in structure, facilitate the installation of nut, and nut is not easy to depart from from loop bar.
The purpose of this utility model realizes by following technical proposals:
A kind of nut anti-falling sleeve, comprises handle, loop bar and nut contact mechanism, and described loop bar one end is connected with handle, and nut contact mechanism is positioned at loop bar other end inside, it is characterized in that: described loop bar other end inside also comprises clamp mechanism and hold-down mechanism.
Described clamp mechanism is shell fragment, and shell fragment is arranged on the breach on loop bar.
Described hold-down mechanism comprises spring and thimble, and thimble is connected with spring, and described thimble is near nut contact mechanism.
As preferably, described nut contact mechanism is regular hexagon hole.
As preferably, described shell fragment has 6.
As preferably, described shell fragment is U-shaped.
As preferably, described thimble does not stretch out nut contact mechanism.
As preferably, described handle adopts insulation material.
The beneficial effects of the utility model: a kind of nut anti-falling sleeve of the utility model, loop bar one end is connected with handle, and inside, one end is provided with clamp mechanism and hold-down mechanism in addition.The utility model is simple in structure, and owing to there being clamp mechanism, nut and pad are clamped, are not easy to depart from from loop bar; Have hold-down mechanism, operating personnel use easier in the time of clamp nut, have improved operating efficiency.
Brief description of the drawings
The Figure of description that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.
Fig. 1 is the structural representation of a kind of nut anti-falling sleeve of the utility model;
Fig. 2 is the structural representation of clamp mechanism and hold-down mechanism;
Mark in figure: 1-handle, 2-thimble, 3-spring, 4-shell fragment, 5-loop bar, 6-nut contact mechanism.
Detailed description of the invention
it should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
According to embodiment of the present utility model, a kind of nut anti-falling sleeve is provided, as shown in Figure 1, comprise: comprise handle 1, loop bar 5 and nut contact mechanism 6, described loop bar 5 one end are connected with handle 5, nut contact mechanism 6 is positioned at loop bar 5 other end inside, and described loop bar 5 other end inside also comprise clamp mechanism and hold-down mechanism.Described clamp mechanism is shell fragment 4, and shell fragment 4 is arranged on (breach is not shown) on the breach on loop bar 5; Described hold-down mechanism comprises spring 3 and thimble 2, and thimble 2 is connected with spring 3, and described thimble 2 is near nut contact mechanism 6.
Preferably, described nut contact mechanism 6 is regular hexagon hole, can put into hex nut.
Preferably, described shell fragment 4 has 6, and nut is played to clamping action.
Preferably, described shell fragment 4 is U-shaped.
Preferably, described thimble 2 does not stretch out nut contact mechanism 6.
Preferably, described handle 1 adopts insulation material, has strengthened like this protection to staff.
Use this nut anti-falling sleeve to carry out when fastening workpiece, first bullet pad, plain cushion are placed in together with nut in handle nut contact mechanism 6, due to the effect of shell fragment 4, bullet pad, plain cushion and nut are stuck in the middle of shell fragment 4, the random angle of rotational sleeve when operation, does not worry that nut and pad drop out.When fastening, the bolt on fastening workpiece withstands thimble 2, and thimble 2 Compress Springs 3 are realized fastening nuts and put in place.Owing to there being clamp mechanism, nut and pad are clamped, are not easy to depart from from loop bar 5; Have hold-down mechanism, operating personnel use easier in the time of clamp nut, have improved operating efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
