Abstract
The invention discloses an expansion nut which comprises a nut body. The nut body comprises a cylindrical fixed part, an expansion part integrally connected with the tail end of the fixed part, a conical boss and a blocking sheet. A through hole is formed in the fixed part and provided with an internal thread. The conical boss and the blocking sheet are sequentially arranged in the through hole and located in the rear portion of the through hole. The maximum diameter of the conical boss is slightly smaller than the inner diameter of the through hole. The periphery of the blocking sheet is connected in the thread of the through hole in a clamped manner. The expansion part comprises at least four expansion claws, and the wall thickness of the expansion claws is gradually increased from inside to outside. The expansion nut is low in requirement for aperture depth and precision of prepunched holes in a wall and convenient to mount, reworking is easy when mounting fails, and the expansion nut can be applied to a storage plate.
Description
Technical field
The present invention relates to link technical field, specifically a kind of expanding nut and the application on shelf thereof.
Background technique
Expanding nut is a kind of common threaded connector.Generally there is following shortcoming in existing expanding nut: the depth requirements that (1) punches on the wall is in advance high, is generally greater than expanding nut length, not so cannot be fixed, cannot satisfy the demands when thickness of wall body is less; (2) expanding nut end drives screw to rotate by electric tool and expands, fitting operation inconvenience; And screw cannot be applied to the installation of shelf, namely use screw rod to replace screw, because the screw rod arm of force is long, not easily pierce; (3) require higher to the aperture precision of porthole, aperture greatly in installation process expanding nut rotate together with screw, cause expanding nut end to expand and to fix with body of wall; (4) failed difficulty is installed to do over again: when aperture is bigger than normal, expanding nut not easily takes out, and playback expanding nut not easily pops, rotate because hole conference is skidded.Therefore, need badly exploitation a kind of to the aperture degree of depth and required precision low, easy for installation, install and unsuccessfully easily do over again and can be applicable to the expanding nut of shelf.
Summary of the invention
The present invention is directed to above-mentioned Problems existing, provide a kind of expanding nut and the application on shelf thereof.
The present invention for achieving the above object, takes following technological scheme to be achieved:
A kind of expanding nut, comprises nut body, bulge, cone boss and catch that described nut body comprises cylindrical fixing part, is connected with fixing part end one; Described fixing part is provided with through hole, and described through hole is provided with internal thread; Described cone boss and catch to be successively set in through hole and to be positioned at through hole rear portion; The maximum diameter of cone boss is more smaller than through hole internal diameter; Described catch card is connected in the screw thread of through hole; Described bulge comprises at least pintongs expansion pawl, and the wall thickness of described expansion pawl increases from inside to outside gradually.
Preferably, described catch diameter is more bigger than through hole internal diameter, is convenient to catch periphery and through hole internal thread connects and fixes.
Preferably, described catch is plastic sheet.The setting of plastic retainer sheet, on the one hand can avoid cone boss in the processes such as installations, transport to drop out, and when another aspect plastic retainer sheet can not affect installation, impact tool is to the active force of cone boss.In the assembly process of expanding nut, only cone boss need be loaded through hole in advance, then disclose in through hole with the Assembly rail being less than through-hole diameter by plastic retainer sheet, the periphery of plastic retainer sheet naturally snaps in screw thread, thus realizes fixing.
Preferably, described expanding nut overall length is 20mm, and described fixing part length is 10 ~ 15mm.
Preferably, described bulge outer wall is provided with annular knurl.Preferably, described bulge outer wall has some grooves.Bulge expand after can with body of wall increasing friction force, not easily loosen.
Preferably, described expansion pawl innermost end wall thickness is consistent with fixing part wall thickness.
Described bulge can be the pintongs expansion pawl of equal portions, also can be six lobe expansion pawls of equal portions, or other equal portions expansion pawls.General 4 ~ 6 equal portions are best, can reduce the dynamics of expansion.
Another object of the present invention is to the openly application of above-mentioned expanding nut on shelf, comprise at least two expanding nut, at least two screw rods and shelf; Described screw rod is provided with the outside thread mated with fixing part through hole internal thread; Described shelf offers the mounting hole mated with screw rod;
First, body of wall is holed, hole depth " length of expanding nut, the expanding nut diameter " aperture " (expanding nut diameter+5 ~ 6mm) in this hole;
Secondly, expanding nut is put into above described holes, cone boss is knocked in expanding nut end by the impact tool adopting diameter to be less than fixing part through hole internal diameter, and bulge expands afterwards and body of wall is fixed;
Finally, be screwed in expanding nut fixing part through hole screw rod one end with hand, the screw rod the other end is inserted in the mounting hole of shelf, and the installation that can realize shelf is fixed.
Preferably, the hole depth of described wall body hole equals the length of expanding nut.
Compared with prior art, beneficial effect of the present invention is as follows:
(1) expanding nut of the present invention to the aperture degree of depth that wall punches and required precision lower, without the need to cross gun drilling, the aperture degree of depth is consistent with expanding nut length can be fastening; Can be compatible to Aperture deviation, even if the diameter in aperture also can light expansion fastening than the large 5 ~ 6mm of expanding nut diameter.
(2) the present invention is easy for installation, and cone boss is knocked in expanding nut end by the impact tool adopting diameter to be less than fixing part through hole internal diameter, and bulge can be fixed with body of wall, without the need to using electric tool after expanding.
(3) expanding nut of the present invention is without the need to supporting with screw, and manually turning screw rod can be connected screw rod one end with the fixing part of expanding nut, is convenient to the installation of shelf, without the need to by other instruments.
(4) setup error can be done over again: when aperture is bigger than normal, and only need be screwed into screw rod can pull out expanding nut; Compatible strong to Aperture deviation during playback expanding nut, can light expansion fastening.
