Abstract
The utility model belongs to the technical field of assembly and relates to a quick-dismounted bolt assembly which comprises a screw (1), a nut (2) and an inserting piece (3). The quick-dismounted bolt assembly is characterized in that an annular ring (1c) is arranged in a position on an optical axis section (1b) close to the right end, the inserting piece (3) is a stripe-shaped plate, and a clamping slot (3a), which stretches along the length direction, is arranged at the lower end of a panel of the inserting piece (3). According to the quick-dismounted bolt assembly, the mounting and dismounting time of the bolt assembly is greatly shortened and the working efficiency is improved.
Description
Technical field
The utility model belongs to the mounting technology field, relates to a kind of quick-release bolt assembly.
Background technique
Present bolt, nut assembly are after connecting two workpiece, and the attachment portion of two workpiece is between bolt head and nut.If want demounting bolt, must earlier nut be unloaded, need swivel nut to enclose more, more time-consuming; Need the same number of turns of swivel nut during installation, could be with nut screwing clamping.Cause the installation and removal speed of bolt assembly very slow, inefficiency.
Summary of the invention
The purpose of the utility model is: propose a kind of quick-release bolt assembly, to shorten the installation and removal time of bolt assembly, increase work efficiency.
The technological scheme of the utility model is: a kind of quick-release bolt assembly; Comprise screw rod 1, nut 2 and inserted sheet 3; Thread section 1a and optical axis section 1b are arranged on screw rod 1, it is characterized in that: there is a circular groove 1c position near right-hand member on optical axis section 1b, and inserted sheet 3 is stripe board; A draw-in groove 3a who stretches is along its length arranged in the lower end of inserted sheet 3 plate faces; The notch of draw-in groove 3a is positioned at the lower edge of inserted sheet 3, and the groove width of draw-in groove 3a is than the big 0.2mm～0.4mm in footpath, the end of circular groove 1c, and the groove depth of draw-in groove 3a is greater than the external diameter of optical axis section 1b.
The utility model has the advantages that: shortened the installation and removal time of bolt assembly greatly, improved working efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of inserted sheet 3 in the utility model.
Embodiment
Explain further details in the face of the utility model down.Referring to figure, 2; A kind of quick-release bolt assembly comprises screw rod 1, nut 2 and inserted sheet 3, and thread section 1a and optical axis section 1b are arranged on screw rod 1; It is characterized in that: there is a circular groove 1c position near right-hand member on optical axis section 1b; Inserted sheet 3 is stripe board, and a draw-in groove 3a who stretches is along its length arranged in the lower end of inserted sheet 3 plate faces, and the notch of draw-in groove 3a is positioned at the lower edge of inserted sheet 3; The groove width of draw-in groove 3a is than the big 0.2mm～0.4mm in footpath, the end of circular groove 1c, and the groove depth of draw-in groove 3a is greater than the external diameter of optical axis section 1b.
For the ease of hand-held inserted sheet 3, on the said inserted sheet 3 plate faces bending is arranged, the side-glance shape that makes inserted sheet 3 is a broken line shape, the groove depth of the distance of draw-in groove 3a bottom land greater than draw-in groove 3a arrived in the position of this bending.
The utility model when mounted; The optical axis section 1b of screw rod 1 is inserted the workpiece mounting hole and stretches out the attachment face of workpiece; The draw-in groove 3a of inserted sheet 3 is snapped in the circular groove 1c, again nut 2 is screwed on the thread section 1a of screw rod 1, another attachment face of workpiece is compressed get final product.If in advance nut 2 is screwed in the appropriate location of screw rod 1, as long as the rotation number of turns seldom can be with Work-sheet pressing.During dismounting, as long as nut 2 is unclamped a button, can extract inserted sheet 3 out, screw rod 1 is taken apart from mounting hole.
