Abstract
The invention discloses an anti-loosening combined bolt nut, which comprises a screw with a screw cap and a nut. The nut and the screw are respectively provided with matched internal and external screw threads; the other end of the screw cap relative to the screw is also provided with a raised head with an external screw thread; and a spring matched with the external screw thread of the raised head is arranged on the raised head. The anti-loosening combined bolt nut has simple structure and low cost and is easy to manufacture; the condition of unevenness between boards is overcome; the combined bolt nut is prevented from being loosened; and the anti-loosening combined bolt nut has a good anti-loosening effect.
Description
Technical field
The present invention is fixed in the assembling bolt nut in the hole about a kind of with part, relates in particular to sheet material assembling bolt nut and connects.
Background technique
The fastening piece that screw bolt and nut is formed is widely used on numerous occasions such as science and technology, production, processing and test and machinery and the instrument and apparatus.Common bolt does not generally all have auto-lock function, is used in general occasion and can satisfies usage requirement basically.But be used in the bigger occasion of some vibrations, because vibration can cause bolt looseness.Especially on vehicle that goes or dynamic instrument and apparatus, this loosening the lighter who is difficult for discovering influences normally carrying out of work, and weight person can lead to a disaster.So, must use to prevent the self-locking screw that becomes flexible in some special occasions.Being laid on over of stone wall surface such as marble or various nogging manyly directly is layed on the wall with cement; But stone wall surface weight is extremely heavy; The single laying with cement combines that firm inadequately problem is arranged easily, in case run into earthquake or build thing aging, will be difficult to avoid coming off of stone wall surface and the loss that causes lives and properties; The use of therefore just developing swell fixture (wall nail) is so as to strengthening combining of stone wall surface or nogging and its behind wall.Traditional swell fixture is many with the sheathed expansion sleeve be combined into of screw rod, and this expansion sleeve is provided with several profile groove, make expansion sleeve one side can receive against and expand outwardly; This screw rod then is provided with the hole enlargement district of oblique cone shape, when user's desire is fixed in metope with this swell fixture, needs to wear a cinclides at metope; Screw rod is penetrated in the cinclides together with expansion sleeve, and expose to cinclides one end spiral shell in screw rod and establish a nut, nut is screwed to expansion sleeve; Can make expansion sleeve one end urgent, and this expansion sleeve is expanded outwardly and closely be resisted against metope in the hole enlargement district of this screw rod, subsequently that a screw rod and a L shaped plate is affixed; On this L shaped plate, set firmly other sheet material B again, but the metope A that this screw is fixed often there is rough situation, makes swell fixture be difficult for being adjusted into equal length in the use by supporting element C; And for keeping the smooth laying of sheet material B; Need to prepare the L shaped plate 14 of multiple size in addition, make number of spare parts many, cause the problem that construction sequence is complicated, the construction material cost is high.Chinese patent CN200920271773.8 discloses a kind of swell fixture, it is characterized in that, includes: the body of rod, and this body of rod is provided with screw thread, and this body of rod one end is provided with linking department; Sleeve, this jacket casing is located at this body of rod, and this sleeve is provided with at least one grooving, and this grooving extends to an end of this sleeve; First nut, this first nut spiral shell is located at this body of rod, and this first nut is between this linking department and this sleeve; Second nut, this second nut spiral shell is located at this body of rod, and this second nut is positioned at the side of this sleeve away from this first nut; Fixed block, this fixed block spiral shell is located at this body of rod, and this fixed block is positioned at this second nut away from this sleeve one side; This second nut and this fixed block can rotate relative to this body of rod and move, and mutual urgent this body of rod that is fixed in of selectivity.But complex structure, cost of production is high, and being difficult to overcome between each sheet material to have rugged situation.
In view of the hole enlargement district that expansion sleeve is claimed out is located at screw rod one end its inconvenience of using is arranged, also have the swell fixture that utilizes a screw tightening that expansion sleeve is claimed out, this swell fixture includes a screw rod; Be arranged with expansion sleeve on the screw rod, and spiral shell is provided with a screw tightening, this screw tightening side view generally is dovetail; So as to expansion sleeve is claimed out; But this kind swell fixture need utilize another nut locking expansion sleeve in use, make expansion sleeve to screw tightening near, the situation of interlock expansion sleeve and screw tightening rotation is arranged when user's lock nut often; Increase the difficulty of set screw; Cause also that the position of screw rod is difficult to precision positioning in the screw, still must link, otherwise between each set sheet material rugged situation will be arranged by L shaped plate and sheet material.
Summary of the invention
Be to solve the deficiency of existing technology, it is a kind of simple in structure that task of the present invention is to provide, and cost of production is low, is convenient to overcome occur being uneven the anti-loosening assembling bolt nut of situation between each sheet material.
The present invention realizes through following technological scheme: anti-loosening assembling bolt nut; Comprise the screw rod and the nut that have nut; Described nut and screw rod are respectively arranged with the internal and external threads that complements one another; Described nut also is provided with respect to the other end of screw rod and has externally threaded plush copper, also is provided with the spring that is complementary with its outside thread on the described plush copper.
Nut of the present invention also is provided with respect to the other end of screw rod and has externally threaded plush copper, also is provided with the spring that is complementary with its outside thread on the described plush copper.Utilize the tight power of bullet of spring, make nut be close to sheet material, overcome between each sheet material and the situation that is uneven occurs, and prevent the assembling bolt nut loosening.
Advantage of the present invention is: simple in structure, cost is low, easy to manufacture, overcome between each sheet material and the situation that is uneven occurs, and prevent the assembling bolt nut loosening, anti-loosening effective.
Description of drawings
Fig. 1 is a specific embodiment of the invention structural representation.
Sequence number among the figure: 1, nut, 2, screw rod, 3, nut, 4, plush copper, 5, spring.
Embodiment
In conjunction with accompanying drawing the specific embodiment of the invention is described in further detail.
Referring to accompanying drawing 1; A kind of anti-loosening assembling bolt nut; Comprise the screw rod 2 and nut 3 that have nut 1; Described nut 3 is respectively arranged with the internal and external threads that complements one another with screw rod 2, and described nut 1 also is provided with respect to the other end of screw rod 2 and has externally threaded plush copper 4, also is provided with the spring 5 that is complementary with its outside thread on the described plush copper 4.
Embodiment is just for the ease of understanding technological scheme of the present invention; Do not constitute restriction to protection domain of the present invention; Every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technological scheme of the present invention all still belongs within the protection domain of the present invention.
