Description
Technical field
The utility model relates to a kind of screw connection structure that is used for fixing connection, relates in particular to a kind of screw connection structure of threaded lining.
Background technique
In structural designs such as engineering goods and low-pressure electronic equipment product, for normal screw or the bolt of adopting that two parts are fixed together as fixed block, screw or bolt are threaded with threaded connection hole on the connected piece.And work as connected piece is relative softer material, as magnalium plate, aluminium sheet, plastics, bakelite, nylon etc., directly with screw or bolt when threaded connection hole on it is connected, because it is not tight that screw or bolt are screwed into the back lock, so its join strength is not enough, when firmly it being screwed, tend to damage inner threaded surface than the threaded connection hole of softwood matter.In order to address the above problem, people adopt a threaded bushing that is provided with internal and external threads to come transition to connect usually.In the use, as shown in Figure 1, earlier smear a layer binder (not shown) respectively at the outside thread face of threaded bushing 2 and the inner threaded surface of threaded connection hole 1, with enhancing threaded bushing 2 and than the join strength between the threaded connection hole 1 of softwood matter, with instrument screw thread lining 2 is overlapped in the threaded connection hole 1 that is screwed into than softwood matter again, the outside thread of threaded bushing 2 is connected with the internal thread of threaded connection hole 1, after treating the adhesive cures between threaded bushing 2 and the threaded connection hole 1, again screw or bolt 3 are screwed in the threaded bushing 2, the internal thread of threaded bushing 2 is connected with the outside thread of screw or bolt 3, with this constitute screw or bolt 3 with than the fixedlying connected of softwood matter threaded connection hole 1, satisfy need of work.
Above-mentioned thread connecting mode has used for many years, but facts have proved and still have deficiency, its reason mainly is: under particular job condition (as high temperature or low temperature environment), spread upon Bond between threaded bushing and the threaded connection hole and lost efficacy easily that (Bond can melt during as high temperature, Bond meeting hardening, fragmentation etc. during low temperature), it is loosening that thereby being connected between threaded bushing and the threaded connection hole can produce, even threaded bushing comes off in threaded connection hole, causes this screw connection structure no longer can satisfy need of work.
Therefore, the utility model provides a kind of screw connection structure of threaded lining to overcome deficiency of the prior art from improving the prior art angle.
Summary of the invention
The utility model purpose provides a kind of screw connection structure of threaded lining, and its purpose mainly is the problem that solves the whole linkage structure inefficacy that screw connection structure causes because of adhesive failure in the prior art under particular job condition.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screw connection structure of threaded lining, form by a threaded connection hole, a threaded bushing and a bolt that is threaded, the outer rim of threaded bushing is provided with outside thread, this outside thread is connected with the internal thread of threaded connection hole, the inner edge of threaded bushing is provided with internal thread, this internal thread is connected with the outside thread of the bolt that is threaded, its innovation is: be concaved with keyway on the outer rim of threaded bushing vertically, be inserted with key pin in the keyway, the end face of this key pin is at the hole wall that radially embeds threaded connection hole.
Related content in the technique scheme is explained as follows:
1. in the such scheme, described " threaded connection hole " is meant and is connected tapped attachment hole set on the member.Described " bolt is threaded " is meant externally threaded linkage section set on the link.Here said link can be a bolt, also can be common component, therefore so-called " bolt is threaded " specifically refers to the outside thread linkage section on the bolt for bolt, and specifically refers to upward extended outside thread linkage section of its material object for common component.
2. in the such scheme, described " end face of key pin " is meant that key pin is exposed to the threaded bushing outer rim, and towards the side of threaded connection hole hole wall.
3. in the such scheme, described keyway is formed by one at least, wherein two or more keyways in the threaded bushing outer circumference to even distribution.
4. in the such scheme, the end face of described key pin is in the internal thread segment that radially is embedded into threaded connection hole hole wall top layer.The implication of this structure is: do not establish keyway on the threaded connection hole hole wall, and the end face of key pin does not further stretch into the hole wall internal layer in the internal thread segment that radially only is embedded into the hole wall top layer.To be screwed into the threaded bushing of keyway in the threaded connection hole earlier in the assembling, then key pin is squeezed in the keyway, the key pin end face axially inserts between threaded bushing and the threaded connection hole to destroy hole wall top layer internal thread segment mode in squeezing into process, wherein the key pin end face has been embedded in the internal thread segment on threaded connection hole hole wall top layer, with this with threaded bushing and threaded connection hole relative fixed.In this structure, it is one of following two kinds that described key pin can adopt:
(1) sectional shape of described key pin and size are equating all that axially wherein the end face of key pin is plane, cambered surface, inclined-plane or " V " shape concave surface.
(2) described key pin is being a wedge-shaped structure axially.
5. in the such scheme, the hole wall upper edge of described threaded connection hole is axially arranged with groove, and the end face of key pin is in radially embedding this groove.This structure need be provided with groove on the threaded connection hole hole wall, this groove need process in advance, also groove will be alignd with keyway after threaded bushing is screwed into threaded connection hole, squeezes into key pin then.This structure is equivalent to key common between the axis hole and connects.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Because the utility model adopts and be concaved with keyway vertically on the outer rim of threaded bushing, is inserted with key pin in the keyway, the end face of this key pin is at the hole wall that radially embeds threaded connection hole; When this screw connection structure uses under particular job conditions such as high temperature, low temperature, even spread upon the adhesive failure between threaded bushing and the threaded connection hole, because the key pin on the threaded bushing is radially embedding threaded connection hole, make that the join strength between threaded bushing and the threaded connection hole is reliable, stable, can satisfy the needs of proper functioning.This screw connection structure can directly use separately, and need not smear Bond between threaded bushing and threaded connection hole, has reduced process step, has saved processing cost.
