In view of the above, the utility model aims to provide a structural design is ingenious, reasonable, and installation rear surface parallel and level is easily installed and the difficult not hard up arc surface carriage screw.
In order to achieve the above purpose, the utility model provides a technical scheme is: the utility model provides an arc surface carriage screw, its includes head, square pole portion and screw rod portion, head, square pole portion and screw rod portion connect gradually, the head is equipped with the sphere arch towards the surface of square pole portion, and another surface is the levelling surface, the one end overall dimension that square pole portion is connected with the head is great, and the other end is the form of dwindling gradually, the surface of screw rod portion is equipped with locking glue film, the levelling surface is equipped with protective coating.
As an improvement of the utility model, the outline of the transverse surface of the square rod part is square, which is beneficial to installation.
As an improvement of the utility model, the protective coating is a Teflon coating. Wear-resisting, corrosion-resistant, insulating nature is good, increase of service life, and this teflon coating can be transferred into the colour unanimous with required installation object surface moreover, and whole harmony is better.
As an improvement of the utility model, the diameter that the head is close to the protruding one end of sphere is less than the diameter of the other end, more does benefit to the round nest position of the mounting hole of being absorbed in the installation object, brings the convenience for the installation.
As an improvement of the utility model, the head, the square rod part and the screw rod part are of an integrated connecting structure, firm in connection and good in structural stability.
The utility model has the advantages that: the utility model has the advantages of ingenious structural design, reasonable arrangement of the spherical protrusions on the inner surface of the head, and capability of enabling the spherical protrusions to be sunk into the round nest positions of the mounting holes of the mounting object on the basis of ensuring the overall structural strength, thereby ensuring the level of the mounting rear surface, having no feeling of tangling and beautiful appearance; the insertion end of the square rod part is gradually reduced, so that the square rod part can be conveniently and quickly inserted into the square hole part of the mounting hole for assembly, and convenience is brought to mounting; after locking, because the surface of screw rod portion is equipped with locking glue film, locking glue film is extruded and produces powerful reaction force, has greatly increased the frictional force between the internal and external screw thread, provides the absolute resistance to the vibration, and the installation is firm, difficult not hard up phenomenon that appears, overall structure is simple in addition, easily realizes, does benefit to popularization and application.
The present invention will be further explained with reference to the drawings and the embodiments.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a schematic bottom view of the present invention.
Detailed Description
Referring to fig. 1 and fig. 2, the circular arc surface carriage screw that this embodiment provided, it includes head 1, square pole portion 2 and screw rod portion 3, head 1, square pole portion 2 and screw rod portion 3 connect gradually, head 1, square pole portion 2 and screw rod portion 3 connection structure as an organic whole, firm in connection, structural stability is good.
The surface of the head part 1 facing the square rod part 2 is provided with a spherical bulge 11, and the spherical bulge 11 can enhance the connection strength between the head part 1 and the square rod part 2 and can sink into the round nest position of the mounting hole of a mounting object during mounting. The height of the spherical protrusions 11 is consistent with the length of the square rod part 2.
The other surface of the head 1 is a flat surface, and preferably, the flat surface is provided with a protective coating 12. The protective coating 12 is preferably a teflon coating. Wear-resisting, corrosion-resistant, insulating nature is good, increase of service life, and this teflon coating can be transferred into the colour unanimous with required installation object surface moreover, and whole harmony is better, and the appearance is pleasing to the eye.
The diameter of the head part 1 close to one end of the spherical bulge 11 is smaller than that of the other end, the whole body is conical, the round pit position of the mounting hole for mounting an object is facilitated to sink into, and convenience is brought to mounting.
The outline of the transverse surface of the square rod part 2 is square, which is beneficial to installation. The square rod part 2 is connected with the head part 1, one end of the square rod part is larger in overall dimension, and the other end of the square rod part is gradually reduced. The inserting end of the square rod part 2 is gradually reduced, the square hole part which can be conveniently and quickly inserted into the mounting hole can be assembled, and convenience is brought to mounting.
The outer surface of the screw rod part 3 is provided with a locking glue layer. After locking, locking glue film is extruded and produces powerful reaction force, has greatly increased the frictional force between the internal and external screw thread, provides the absolute resistance to the vibration, and difficult appearance becomes flexible phenomenon, and the installation is firm.
During installation, because the spherical protrusions 11 are reasonably arranged on the inner surface of the head part 1, the spherical protrusions 11 can enhance the connection strength between the head part 1 and the square rod part 2, and the structural strength is high. The spherical protrusions 11 are positioned on the inner surface of the head 1 and can sink into the round nest position of the mounting hole of the mounting object when being mounted, so that the outer surface of the head 1 is ensured to be flush with the surface of the mounting object after being mounted, and the mounting head is free from being glancing and attractive in appearance; the insertion end of the square rod part 2 is gradually reduced, so that the square rod part can be conveniently and quickly inserted into a square hole part of the mounting hole for assembly, and convenience is brought to mounting; after locking, because the surface of screw rod portion 3 is equipped with locking glue film, locking glue film is extruded and produces powerful reaction force, has greatly increased the frictional force between the internal and external screw thread, provides the absolute resistance to the vibration, and difficult not hard up phenomenon appears, and the installation is firm.
Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
