Fig. 2 is a schematic view of the present invention in a partial sectional structure.
Fig. 3 is a schematic side view of the present invention.
Detailed Description
Referring to fig. 1, fig. 2 and fig. 3, the waterproof screw with a rubber ring threaded on a cup head provided by the embodiment includes a head 1, a rod 2 connected to the head 1, and a sealing ring 3, preferably, the rod 2 and the head 1 are an integral connecting structure, and are firmly connected and have good structural stability.
Be equipped with recess 11 on the terminal surface of the body of rod 2 of head 1 orientation, this recess 11 central point is connected to the one end of the body of rod 2 and puts, the peripheral position of this recess 11 form with the seal groove 111 of 3 looks adaptations of sealing washer, the one end surface that the body of rod 2 stretched into recess 11 forms assembly portion 21 for the smooth surface, the preferred, the length of assembly portion 21 with the degree of depth of recess 11 is unanimous mutually, avoids assembly portion 21 salient, ensures that the screw of the body of rod 2 can twist into the screw completely. Be equipped with spacing sunken 211 on the surface of assembly portion 21, this spacing sunken 211 can carry on spacingly to sealing washer 3, avoids shifting, further promotes stability, and it is convenient to bring for the installation use, improves work efficiency.
The depth of the sealing groove 111 is one half to two thirds of the thickness of the sealing ring 3, and the sealing ring 3 is positioned on the sealing groove 111 to ensure that part of the sealing ring 3 protrudes from the head 1 to the end face of the rod body 2 to be contacted with the assembling face, so as to ensure the sealing effect. The head 1 is a cylindrical hole. And the other end face of the head part 1 is provided with an inner hexagonal hole 12. Compared with an outer hexagonal screw, the screw has small volume and is delicate. And other parts cannot be influenced, other space is occupied, the screw can be installed at a deeper position during installation, and the outer hexagonal screw is relatively larger and cannot be installed at a certain specific position. In this embodiment, the waterproof screw with the rubber ring inserted in the cup head is integrally formed by adopting SUS304 stainless steel material, and has no magnetic attraction effect, and therefore, preferably, a concave hole is formed in the inner wall of the hexagonal socket 12. After the disassembly, the hook foot of the hook piece can be clamped into the concave hole, and the hook piece is lifted up at the moment to conveniently and quickly take the head part 1 out, so that the head part is conveniently taken out. In this embodiment, the cross section of the sealing groove 111 is arc-shaped, and can be more matched with the shape of the sealing ring 3. Because the cross-sectional profile of the sealing ring 3 is circular. Preferably, an arc-shaped concave position 31 is arranged on the contact surface of the sealing ring 3 and the assembling surface, when the sealing ring is matched with the assembling surface, the arc-shaped concave position 31 is changed into a plane by extrusion and is closely attached to the assembling surface, and negative pressure is formed between the deformed arc-shaped concave position 31 and the assembling surface, so that the matching tightness is further improved.
During the use, sealing washer 3 cover is established on assembly portion 21 to be located in seal groove 111 and spacing sunken 211, when the screw assembly of twisting, the body of rod 2 can twist the screw completely and through 1 roof pressure sealing washer 3 of head closely attached on the assembly surface of screw peripheral position, the cooperation is inseparable, and water-proof effects 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.
