Abstract
The utility model discloses a water drain valve fastening screw cap and relates to a connecting piece used for fastening and connecting a water drain valve in a water drain hole of a wash basin. The water drain valve fastening screw cap is mainly composed of a brass screw cap and a connecting sleeve, an integrated fastening screw cap structure which enables the brass screw cap to be assembled on the top of the connecting sleeve in a spline meshing mode and to enable the brass screw cap and the connecting sleeve to be integrally formed in an injection mode is adopted, the fastening screw cap of the integrated structure can be manually screwed through the connecting sleeve, and therefore fastening connection can be achieved without a dedicated open spanner, and the mounting process is simple and fast. Meanwhile, the fastening connection of the water drain valve fastening screw cap can be easily achieved even in a narrow mounting space below the wash basin, the operation is very flexible and saves labor, and the improved fastening screw cap can not only meet human motion dynamics when screwed, but also effectively ensure the connecting strength and rigidity of threads, and has the advantages of being simple in structure, firm in connection, reliable and the like.
Description
Technical field
The utility model relates to a kind of fastening nut structure, refers in particular to for the fastening discharging valve fastening nut that is installed on the washbasin of discharging valve.
Background technique
In daily life, various kitchen guarding's products are must be obligato, and the discharging valve that is installed on the washbasin is exactly one of them representative instance.At present, most of discharging valve realizes screwing connection in that the hexagon fastening nut that all adopts several millimeters thick when fastening is installed on the market.And will find a difficult problem when people buy various discharging valve back home when installing, the fastening of fastening nut must could be operated by a special open-end wrench.And the rotary manipulation that uses open-end wrench to carry out fastening nut in the narrow and small installing space below washbasin is also wasted time and energy, and has gone up even connect reluctantly, also can exist connection inadequately firmly, defective reliably.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of installation simple, quick, flexible operation, laborsaving, be connected firmly, reliable discharging valve fastening nut, this fastening nut is simple in structure, and can effectively guarantee join strength and the rigidity of screw thread.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of discharging valve fastening nut comprises brass nut and connecting sleeve, is equipped with and integrated injection molding so that serration is meshing between described brass nut and the connecting sleeve.
Described brass nut top is provided with collar flange, and this collar flange is coated on the connecting sleeve end face.
Described brass nut middle part is provided with annular groove, the corresponding ring-type convex shoulder that is equipped with described annular groove that is provided with at the connecting sleeve inwall.
Described spline is arranged on the serration on the outer circumferential face of brass nut bottom.
Described connecting sleeve is plastic secondary ladder axle sleeve, and the bottom excircle dimension of this connecting sleeve is greater than the top excircle dimension.
Described connecting sleeve bottom outer peripheral surface is provided with six along the attachment post that extends axially and do circumference uniform distribution of connecting sleeve, and each attachment post all is semi-cylindrical.
Compared with prior art, the utility model mainly be a kind of with the brass nut with the meshing integrated type fastening nut structure that is fitted in connecting sleeve top and integrated injection molding of spline, the fastening nut of this monolithic construction can manually screw by connecting sleeve, also can realize being fastenedly connected so need not special open-end wrench, installation process is simple, quick.Simultaneously, even being fastenedly connected in the installing space narrow and small below washbasin of it also can easily realize, operate very flexible, laborsaving, fastening nut after the improvement can meet human motion dynamics when screwing, can effectively guarantee join strength and the rigidity of screw thread again, also have simple in structure, be connected firmly, advantage such as reliable.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1 ~ shown in Figure 5,1. brass nut, 11. serrations, 12. collar flanges, 13. annular grooves, 2. connecting sleeve, 21. attachment posts, 22. ring-type convex shoulders, 3. discharging valve, 4. washbasin, 5. seal ring, 6. plastic spacer, 7. sealing gasket, 8. connecting tube.
The discharging valve fastening nut, as shown in Figure 1 and Figure 2, it is a kind of for the connected element that discharging valve 3 is fastenedly connected in the dewatering orifice of washbasin 4, mainly is to be made of brass nut 1 and plastic connecting sleeve 2.
Described brass nut 1 as shown in Figure 3, its top is provided with size greater than the collar flange 12 of nut body, the middle part be provided with one the circle annular groove 13, the bottom outer circumferential face is provided with serration 11.
The serration 11 of described brass nut 1 by the bottom be meshing be fitted in connecting sleeve 2 tops and with the connecting sleeve integrated injection molding, it can effectively guarantee the internal thread strength and stiffness of brass nut 1; Described connecting sleeve 2 inwalls are provided with the annular groove 13 at brass nut 1 middle part and make closely equipped ring-type convex shoulder 22, and after brass nut 1 and connecting sleeve 2 were injection molded into monolithic construction, the collar flange 12 at brass nut 1 top just in time was coated on connecting sleeve 2 end faces; End face, the ring-type convex shoulder 22 of the collar flange 12 on the described brass nut 1, annular groove 13 and plastic sheath 2 have constituted brass nut 1 jointly to be fixed in the axially locating at connecting sleeve 2 tops.
Described connecting sleeve 2 as shown in Figure 4, it has adopted secondary ladder axle sleeve, the bottom excircle dimension of this connecting sleeve 2 is greater than the top excircle dimension, and is provided with six along the attachment post that extends axially and do circumference uniform distribution 21 of connecting sleeve 2 at the bottom outer peripheral surface, and each attachment post all is semi-cylindrical.When this structural design can and be passed through six attachment post 21 stressed rotations at finger grip connecting sleeve 2, better meet human motion dynamics, make operating process lighter, laborsaving.
The utility model is mainly used in the installation of fastening discharging valve 3 on washbasin 4 and connects, its mounting structure as shown in Figure 5, the discharging valve 3 that the bottom is connected with connecting tube 8 is installed in the dewatering orifice on the washbasin 4, between discharging valve 3 and washbasin 4 end faces sealing gasket 7 is set, then fastening nut being made screw thread from discharging valve 3 bottoms with manual mode inwardly screws, also seal ring 5 need be set between the collar flange 12 at brass nut 1 top and washbasin 4 bottom surfaces and plastic spacer 6 seals, because the attachment post 21 on connecting sleeve 2 and the connecting sleeve can play stressed effect preferably, also can reach connectivity robustness and reliability preferably so manually screw fastening nut.
