The conventional screws are various in types, and the BU head screw is one of the screws, which is also called a button head screw. Although the sealing device can meet the function of connecting and fastening objects, the sealing device is pressed on the objects by the top of the head to achieve the sealing effect, the sealing effect is relatively poor, sealing rings are sleeved on the rod body at places with high waterproof requirements, and the sealing rings are easily damaged due to the fact that the outer surface of the rod body is provided with threads, so that the sealing waterproof effect is affected; meanwhile, in the assembling process, the sealing ring is easy to slip off and needs to be held by hands, so that inconvenience is brought to installation and use.
SUMMERY OF THE UTILITY MODEL
Not enough to the aforesaid, the utility model aims to provide a structural design is ingenious, reasonable, and is sealed effectual, and rubber ring waterproof screw is worn to easy to assemble's BU head.
In order to achieve the above purpose, the utility model provides a technical scheme is:
the utility model provides a BU head wears rubber ring waterproof screw, its includes the head, the body of rod and the sealing washer that is connected with this head, and the inner circle diameter of this sealing washer is greater than the external diameter of the body of rod, this sealing washer include circular ring body and a plurality of be centre of a circle symmetry and set up the branch claw on this circular ring body inner wall, the free end of all branch claws extends and can contradict on the outer peripheral face of the body of rod to the centre of a circle position of circular ring body simultaneously, the head towards the body of rod on the surface correspond the body of rod periphery outside position be equipped with the annular assembly groove of circular ring body looks adaptation.
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 an optimal scheme of the utility model, circular ring body and branch claw connection structure as an organic whole, firm in connection easily realize.
As a preferred scheme of the utility model, the external diameter of branch claw is less than the thickness of circular ring body. The circular ring body can be fully contacted with the assembly surface to form a closed space, and the sealing effect is good.
As a preferred embodiment of the present invention, the outer diameter of the supporting claw is equal to one third of the thickness of the circular ring body. The depth of the annular assembling groove is equal to one third of the thickness of the circular ring body. Can let a part of circular ring body fall into annular assembly groove and carry on spacingly, the claw top touches on the head towards the surface of the body of rod just simultaneously.
The utility model has the advantages that: the utility model discloses a structural design is ingenious, reasonable, and the inner circle diameter of sealing washer is greater than the external diameter of the body of rod effectively reduces the sealing washer by the possibility of the external screw thread damage on the body of rod, ensures sealed water-proof effects and life, contradicts on the outer peripheral face of the body of rod through a claw simultaneously, plays the fixed purpose in location, and it is convenient to use for the installation, improves work efficiency, still carries on spacingly through annular assembly groove to the sealing washer in addition, reduces the sealing washer and easily appears aversion or deformation when the assembly, further guarantees complex compactness, and water-proof effects is good.
The present invention will be further explained with reference to the drawings and the embodiments.

Detailed Description
Referring to fig. 1 to 5, the BU head-wearing rubber ring waterproof screw provided by the embodiment includes a head 1, a rod body 2 connected with the head 1, and a sealing ring 3, where the rod body 2 and the head 1 are an integral connecting structure, and are firmly connected and have good structural stability.
The inner circle diameter of sealing washer 3 is greater than the external diameter of the body of rod 2, and the inner circle diameter of sealing washer 3 is greater than the external diameter of the body of rod 2 effectively reduces the possibility that sealing washer 3 is damaged by the external screw thread on the body of rod 2, ensures sealed water-proof effects and life. Referring to fig. 4 and 5, the sealing ring 3 includes a circular ring body 31 and a plurality of supporting claws 32 arranged on the inner wall of the circular ring body 31 in a circle-center symmetry manner, in this embodiment, the number of the supporting claws 32 is ten. In other embodiments, the number of the supporting claws 32 can be six, eight, etc. The circular ring body 31 and the support claws 32 are of an integrated connecting structure and are firmly connected. In this embodiment, the sealing ring 3 is formed by integrally injection molding silica gel, and is easy to implement.
The free ends of all the support claws 32 extend towards the center of the circular ring 31 and can be abutted against the outer circumferential surface of the rod body 2, namely, the connecting lines of the free ends of all the support claws 32 can form a circular area. The diameter of the circular area is equal to or slightly smaller than the outer diameter of the rod body 2. The cross-sectional profile of the leg 32 is circular.
An annular assembling groove 12 matched with the circular ring body 31 is arranged on the surface of the head part 1 facing the rod body 2 and corresponds to the outer side position of the periphery of the rod body 2. The other surface of the head part 1 is provided with an inner hexagonal groove 11 to be conveniently matched with an inner hexagonal tool. The annular assembling groove 12 can limit the sealing ring 3, reduce the phenomenon that the sealing ring 3 is easy to shift or deform during assembling, further ensure the matching tightness and have good waterproof effect
The outer diameter of the prongs 32 is preferably smaller than the thickness of the circular ring 31. The circular ring body 31 can be fully contacted with the assembling surface to form a closed space, and the sealing effect is good. Preferably, the outer diameter of the support 32 is equal to one third of the thickness of the circular ring 31. The depth of the annular assembly groove 12 is equal to one third of the thickness of the circular ring 31. A part of the circular ring 31 can be dropped into the annular assembly groove 12 for limiting, and the support claws 32 just abut against the surface of the head 1 facing the rod body 2.
During the use, pass the body of rod 2 and make circular ring body 31 move to annular assembly groove 12 in the circular region that the free end of a claw 32 formed, at this moment, through the support location of a claw 32, realize with sealing washer 3 location fixed body of rod 2 on, be difficult for droing and bring the convenience for the installation. After the rod body 2 is screwed into the screw hole and locked, the circular ring body 31 is tightly attached to the assembling surface at the peripheral position of the screw hole by jacking the head part 1, the matching is tight, and the waterproof effect is good.
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. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Like the above-mentioned embodiment of the present invention, other screws obtained by adopting the same or similar structure are all within the protection scope of the present invention.
