SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model aims to provide a structural design is ingenious, reasonable, and sealed effectual, and rubber ring waterproof screw is worn to easy to assemble's umbrella head area step.
In order to achieve the above purpose, the utility model provides a technical scheme is: the utility model provides an umbrella head area step wears rubber ring waterproof screw, its includes the head, the body of rod and the sealing washer that is connected with this head, the body of rod with the radial increase of one end that the head is connected forms step portion, is equipped with spacing platform on the outer peripheral face of this step portion, the head is equipped with annular assembly groove towards the peripheral outside position that corresponds step portion on the surface of the body of rod, and the degree of depth in this annular assembly groove does five-eighths to seven-eighths of the thickness of sealing washer, the sealing washer passes through interference fit and sets up in annular assembly groove.
As a preferred scheme of the utility model, the other surface of the head is in a spherical convex shape, so that the phenomenon that the sharp corner hurts people and objects is avoided.
As a preferred scheme of the utility model, the cross section appearance profile of sealing washer is circular, the cross section appearance profile of annular assembly groove is the C font for the opening of annular assembly groove has certain fold nature, can inject the sealing washer in the annular assembly groove, but can ensure that the sealing washer has partly from the annular assembly groove opening arch, has sealed effect.
As an optimized proposal of the utility model, the rod body and the head are connected as an organic whole, firm in connection and good in structural stability.
As a preferred scheme of the utility model, the quantity of spacing platform is two, and the symmetry sets up on the outer peripheral face of step portion, and it is effectual to inject.
As a preferred scheme of the utility model, the interval between two step portions equals the external diameter of the body of rod, the external diameter of step portion is greater than the external diameter of the body of rod, step portion and the body of rod set up for the concentric circles for the length of step portion can extend, and then increases the area of step portion, and structural strength is big.
The utility model has the advantages that: the utility model has the advantages of ingenious and reasonable structural design, the limiting platform is arranged on the step part, after the assembly hole matched with the outline of the assembly hole is arranged, the limiting lug boss of the assembly hole can be abutted against the limiting platform to play a role in circumferential limitation, and during assembly, the head part is not required to be limited by a screwdriver; the head corresponds the periphery outside position of step portion and is equipped with annular assembly groove for the inner circle size of sealing washer is greater than the external diameter of the body of rod effectively reduces the sealing washer and by the possibility of the external screw thread damage on the body of rod, ensures sealed water-proof effects and life, and annular assembly groove can be fixed a position the sealing washer centre gripping on the head in addition, realizes the fixed purpose in location, and it is convenient to bring for the installation use, improves work efficiency.
The present invention will be further explained with reference to the drawings and the embodiments.
