Abstract
The invention discloses an anti-falling structure of a screw mounting sleeve. The anti-falling structure comprises an annular boss and a cylindrical stopper, wherein the annular boss is arranged in an inner hole of the mounting sleeve, the internal diameter of the annular boss is larger than the diameter of a screw, the cylindrical stopper is provided with a screw hole corresponding to the screw and sleeved with the screw, and the outer diameter of the cylindrical stopper is smaller than the diameter of the inner hole of the mounting sleeve and is larger than the internal diameter of the annular boss. Preferably, the annular boss is arranged at one end of the inner hole of the mounting sleeve corresponding to a nut of the screw. The anti-falling structure is capable of preventing falling of the mounting sleeve on the screw, so that labor intensity is reduced and damage to the mounting sleeve is prevented.
Description
Technical field
The present invention relates to a kind of screw rod installation sleeve anti-drop structure.
Background technique
Screw rod is a kind of use fastening piece very frequently, some screw arrangement has installation sleeve, to prevent screw rod from moving vertically, the internal diameter of existing installation sleeve is greater than the diameter of screw rod, and it is sheathed on screw rod, in transportation process, installation sleeve easily comes off, and when causing installing screw rod, needs the installation sleeve come off is found and is again sheathed on screw rod, thus increase the workload of workman, and installation sleeve easily damages.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of screw rod installation sleeve anti-drop structure, thus overcome existing screw rod installation sleeve and hold caducous shortcoming.
For achieving the above object, the invention provides a kind of screw rod installation sleeve anti-drop structure, wherein, comprising: annular boss, it is arranged in the endoporus of installation sleeve, and the internal diameter of this annular boss is greater than the diameter of screw rod; And cylinder block, it is provided with the screw corresponding with screw rod to be sheathed on screw rod; The external diameter of this cylinder block is less than the diameter of the endoporus of installation sleeve, and the external diameter of this cylinder block is greater than the internal diameter of described annular boss.
Preferably, in technique scheme, described annular boss is arranged at the endoporus of installation sleeve one end corresponding with the nut of screw rod.
Compared with prior art, the present invention has following beneficial effect:
The present invention arranges annular boss by the endoporus at installation sleeve, and on screw rod sheathed cylinder block, thus prevent installation sleeve from coming off, it is simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation according to screw rod installation sleeve anti-drop structure of the present invention.
Main Reference Numerals illustrates:
1-screw rod, 11-nut, 2-installation sleeve, 21-annular boss, 3-cylinder block.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1, a kind of embodiment according to the specific embodiment of the invention is: a kind of screw rod installation sleeve anti-drop structure, it comprises annular boss 21 and cylinder block 3, annular boss 21 is arranged in the endoporus of installation sleeve 2, and the internal diameter of this annular boss is greater than the diameter of screw rod 1 with the endoporus making screw rod 1 can pass through installation sleeve 1; Preferably, annular boss 21 is arranged at the endoporus of installation sleeve 2 one end corresponding with the nut 11 of screw rod 1.Cylindrically, it is provided with the screw corresponding with screw rod 1 to be sheathed on screw rod 1 to cylinder block 3; The external diameter of this cylinder block 3 is less than the diameter of the endoporus of installation sleeve 2, and the external diameter of this cylinder block 3 is greater than the internal diameter of annular boss 21.
When installation sleeve 2 is installed on screw rod 1, first installation sleeve 2 is sheathed on screw rod 1, then cylinder block 3 is screwed on screw rod 1, external diameter due to cylinder block 3 is less than the diameter of bore of installation sleeve 2 and is greater than the internal diameter of annular boss 21, when installation sleeve 2 skids off, its annular boss 21 is blocked by cylinder block 3, thus can prevent installation sleeve 2 from coming off, with the damage of the workload and installation sleeve 2 that reduce workman.And cylinder block 3 can be contained in the endoporus of installation sleeve 2, to avoid the use affecting screw rod 1 and installation sleeve 2.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
