Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As a first embodiment of the present invention, as shown in fig. 2-3, an oil leakage preventing structure, including screw 1 and the upper seal cushion 21 and the lower seal cushion 22 which are arranged below screw 1, the upper seal cushion 21 and the lower seal cushion 22 mutually support and cooperate and the middle of the upper seal cushion 21 and the lower seal cushion 22 forms a communicating hole 23 of stepping down, the upper end face of the upper seal cushion 21 is provided with an upper seal groove 211 at a position close to the hole 23 of stepping down, the lower end face of the lower seal cushion 22 is provided with a lower seal groove 221 at a position close to the outside, and the upper seal groove 211 and the lower seal groove 221 are respectively embedded with a first seal ring 24 and a second seal ring 25.
After adopting above-mentioned structure, compared with the prior art, this is novel to have screw 1, upper seal cushion 21 and lower seal cushion 22 are gone up and down to be inserted and are arranged in between screwhead and the 1 interface of screw after good, 1 screw in screw interface in-process of screw extrudes two seal cushion gradually, make upper seal cushion 21 upper surface and screwhead lower surface closely laminate, lower seal cushion 22 lower surface and 1 interface of screw go up global closely laminating, first sealing washer 24 and second sealing washer 25 also paste because of extrusion deformation and establish at screwhead or screw interface simultaneously, consequently profit can not reveal between seal cushion and screwhead or screw interface global, thereby reach sealed effect, moreover, the steam generator is simple in structure ingenious, high durability and convenient installation, the environmental protection.
As a second embodiment of the present invention, as shown in fig. 4, the lower seal cushion block 22 is in an inverted L shape, the lower seal block 22 includes a horizontal portion 222 and a vertical portion 223 which are connected vertically, and the lower seal groove 221 is disposed on the lower end surface of the vertical portion 223. After adopting above-mentioned structure, this novel leak protection oil structure is applicable in the heterotypic screw hole that has the boss, vertical portion 223 can be based on the dimensional design transformation of boss, makes this novel leak protection oil structure can stably be fixed in on the boss screw hole and be difficult for rocking the skew, increases the fastness of leak protection oil structure installation, further strengthens the leak protection effect.
As a third embodiment of the present invention, as shown in fig. 5, the oil leakage preventing structure further includes a sealing tube portion 26 and a sealing piece portion 27, the sealing tube portion is matched with the recessed hole 23, the inner end of the sealing piece portion 27 is vertically connected to the lower end of the sealing tube portion 26, a through hole matched with the sealing tube portion 26 is formed in the middle of the sealing piece portion 27, and the upper end of the sealing tube portion 26 and the outer end of the sealing piece portion 27 are respectively connected to the first sealing ring 24 and the second sealing ring 25. Because the plane that screw 1 and screw hole are connected leads to up end unevenness because of atress and friction, the up end wearing and tearing that can make the screw hole, and when fastening screw 1, unevenness's surface makes down sealed cushion 22 can not closely laminate with the up end of screw hole, and then produces the clearance, gets into the screw hole from clearance seepage profit easily. After adopting above-mentioned structure, when locking screw 1, sealing plate portion 27 is because of receiving the downward extrusion of the pressure that comes from screw 1, closely laminates with the up end of screw hole unevenness, and sealing plate portion 27 is out of shape and is filled up in the clearance of terminal surface unevenness, and sealing plate portion 27 has increased sealing area, prevents that the profit from flowing into the screw hole in the clearance, the effectual leak protection performance that has strengthened.
Preferably, the seal tube portion 26, the seal piece portion 27, the first seal ring 24, and the second seal ring 25 are integrally injection-molded using a rubber material. And an integrated injection molding technology is adopted, so that the sealing element is not easy to damage and break, and the strength of the sealing element is enhanced. And the sealing element can have better deformation capability, thereby enhancing the sealing performance of the sealing element. Finally, four can realize blocking with last seal groove and lower seal groove mutually for a community, and the restriction of mutually supporting makes wholly difficult from the sealing cushion and drops, also difficult skew position when the screw rotates, and stability is better.
Preferably, the lower end surface of the upper seal cushion block 21 is provided with a cross-shaped groove 212, and the upper end surface of the lower seal cushion block 22 is provided with a cross-shaped projection 224 matching with the cross-shaped groove 212. After adopting above-mentioned structure, can make lower seal cushion 22 and the cooperation of last seal cushion 21 more firm, effectively prevent skew and dislocation between the cushion.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
