Description
Technical field:
The present invention relates to a kind of fastening piece, especially a kind of inserting-directly type bolt fastener for square bar.
Background technique:
At present, the fastening piece that generally uses is a bolt.Bolt is by screw thread structural member to be connected, fixes; Because the relation of screw thread and screw rod, the bolt mobile jib all is the cylindrical body mobile jib, when the circular hole of cylindrical body mobile jib (bolt) and structural member is used: 1. screw rod can be played (cunning) commentaries on classics during singlehanded nutting, must be with two spanners ,-holding bolt head ,-just can tighten turning nut,. a bolt, be difficult for positioning being connected member, necessary two above bolts could be located.2. match with nut could connector element for screw rod.
Summary of the invention:
Existing in order to solve (bolt) fastening piece: bolt can be beaten (cunning) during singlehanded nutting changes and is difficult for positioning being connected member, screw rod match with nut could connector element problem, the invention provides a kind of inserting-directly type bolt fastener for square bar, be called for short: the square bar fastening piece; This square bar fastening piece: 1. when one hand turned nut, the square cylinder mobile jib can not beaten (cunning) to be changeed, and only just can position being connected member with one (square bar fastening piece); 2. the square hole that directly inserts member just can connect and fix.
The present invention solves the method that its technical problem adopts: 1. the cylindrical body that improves former bolt mobile jib is a square cylinder, and the inclined-plane plug (or thread head) that 2. adopts the back to play platform is insertion end.The square bar fastening piece comprises fixed end, mobile jib and insertion end; Fixed end is circular arc head or thread head, and the mobile jib cross-section is the square cylinder of square; (fixed end is the rear end, and with respect to fixed end, insertion end is a front end) insertion end is for being arranged on the mobile jib front end, and the inclined-plane plug or the thread head of platform played in the back on two symmetrical faces, and the inclined-plane plug-shaped becomes low early and high after inclined-plane; The platform of inclined-plane plug and mobile jib plane form miter angle, can effectively block member; The mobile jib front end is provided with contraction joint; And the spring washer that is used; Square hole flat washer.Use the square bar fastening piece, when one hand turned nut, the square cylinder mobile jib can not beaten (cunning) to be changeed, and only just can position being connected member with one (square bar fastening piece); When using insertion end to play the square bar fastening piece of inclined-plane plug of platform as the back, the first spring washer of on mobile jib, packing into, when the square hole of inclined-plane plug insert structure part of platform is played in (square bar fastening piece) back, the inclined-plane plug that is extruded draws in (contraction joint), after the inclined-plane plug passed the square hole of structural member, the inclined-plane plug automatically springed open, " platform " company of blocking member of plug back, inclined-plane, utilize the elastic card stressed joint member that is contained in the spring washer on the mobile jib in advance, the connection of realization member and fixing; Insertion end is the square bar fastening piece that the inclined-plane plug of platform is played in the back, and the square hole that directly inserts member just can connect and fixed component.
Insertion end is that square bar fastening piece, the spring washer that the inclined-plane plug of platform is played in the back must adopt steel making preferably, to guarantee having enough elasticity (power), the square bar fastening piece of insertion end thread head, square hole flat washer can adopt common iron to make.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is that fixed end is that circular arc head, insertion end are the stereogram that the square bar fastening piece of the inclined-plane plug of platform and thread head is played in the back.
Fig. 2 is that fixed end is a thread head, and insertion end is the stereogram of the square bar fastening piece of the back inclined-plane plug that plays platform.
Fig. 3 is the accessory schematic representation of square bar fastening piece.
1. circular arc heads among the figure, 2. mobile jib, 3. inclined-plane plug, 4. contraction joint, 5. thread head, 6. spring washer, 7. square hole flat washer, the platform that A. inclined-plane plug rises later and mobile jib plane formation miter angle.
Embodiment:
In Fig. 1, circular arc head (1), inclined-plane plug (3), contraction joint (4), platform that the inclined-plane plug rises later and mobile jib plane form miter angle (A), the square bar fastening piece of thread head (5).
In Fig. 2, fixed end is thread head (5), and insertion end is the square bar fastening piece that the inclined-plane plug (3) of platform is played in the back.
In Fig. 3, the accessory spring washer (6) of square bar fastening piece, square hole flat washer (7).
The drawing of drawing square bar fastening piece and accessory with reference to accompanying drawing 1,2,3 is made in the specific implementation: mobile jib part: comprise circular arc head (1), square cylinder mobile jib (2), the making of (platform is played in the back) inclined-plane plug (3) can be made mould in advance and finish by punching press; Fixed end (or insertion end) is equipped with the nut that matches again for thread head can pass through the thread-rolling machine thread rolling.Spring washer (6), square hole flat washer (7) utilize existing manufacturing technology to make.Making fixed end is circular arc head (1) or thread head (5), and insertion end is the square bar fastening piece that the inclined-plane plug (3) of platform is played in the back, and spring washer (6), must adopt steel preferably, to guarantee to have enough elasticity (power); The square bar fastening piece of insertion end thread head (5), square hole flat washer (7) can adopt common iron to make.
Use fixed end to be circular arc head (1), when insertion end is the square bar fastening piece of the back inclined-plane plug (3) that plays platform, in the square hole of the structural member that the insertion needs connect behind the first spring washer of packing on mobile jib, when the square hole of inclined-plane plug (3) insert structure part of platform is played in (square bar fastening piece) back, the inclined-plane plug (3) that is extruded draws in contraction joint (4), after inclined-plane plug (3) passes the square hole of structural member, automatically spring open, the platform (A) of inclined-plane plug (3) back effectively blocks member, utilize the elastic card stressed joint member that is contained in the spring washer (6) on the mobile jib in advance, the connection of realization member and fixing; When using insertion end, after thread head injects the square hole of structural member, directly tighten the nut that matches with it just as the square bar fastening piece of thread head; Insertion end is that the square bar fastening piece of thread head injects and only to need behind the square hole of member once can fastening nut spanner; When using insertion end, thread head (5) is screwed in the structural member circular hole of being furnished with the internal thread adaptive fixingly earlier, on the inclined-plane of insertion end plug, connects and fixed component again with it as the square bar fastening piece of thread head (5).In the use, if (square) mobile jib is longer than the thickness of structural member, can be in the insertion end abundant square hole flat washer of packing into, till clamping.
The square bar fastening piece is characterised in that: the square bar fastening piece, and accurate positioning when turning nut, can not beaten (cunning) and change; Use a square bar fastening piece, just can accurately locate member; When using insertion end to play the square bar fastening piece of inclined-plane plug of platform as the back, directly the square hole of insert structure part just can connect and fix; During dismounting, folder holds together inclined-plane plug (3) mobile jib to be withdrawed under the elastic force effect of spring washer; In the use: loading, unloading rapidly, conveniently.Compare with existing bolt: save used instrument.
