Abstract
The utility model discloses a kind of screw packing ring, belong to packing ring, be made up of metallic shim and rubber sheet gasket, an open-work is offered in the middle of metallic shim and rubber sheet gasket, the open-work of metallic shim and rubber sheet gasket centre is radially equipped with the pointed fastening part of multiple triangle, internal diameter between fastening part is greater than the internal diameter of screw thread, and be less than the external diameter of thread, and fastening part is canine tooth shape, its fastening part is made to be only limited to the thread localized contact of front end and screw, to effectively reduce the damage of thread, and the metallic shim of packing ring and screw are all metal material, arbitrary canine tooth shape fastening part of metallic shim is only needed to contact with screw, just can make tool conductive effect between packing ring and screw, when making screw carry out powder rust proof paint, can uniform adsorption on the surface of packing ring and screw.
Description
Technical field
The utility model belongs to packing ring.
Background technique
When generally carrying out outdoor engineering, the instrument such as screw and packing ring can be used, and the manufacture of packing ring is first about to tinsel and sheet rubber bind, carry out die-cut making again, and for preventing screw and packing ring from getting rusty, the most often carry out antirust treatment in electrostatic spraying mode, application can be protected the surface of screw and packing ring, it is prevented to be subject to moisture attack in air and Quick Oxidation, and electrostatic spraying is atomized by the Metallic Nozzle At The Ingot of high-pressure electrostatic producer by coating spray and produce negative electricity, and screw and packing ring utilize the tape transport of positive electricity, make screw and conveyor belt produce electric action and also produce positive electricity, utilize positive and negative attracting principle, electronegative coating will by the screw of positively charged or packing ring coated, and then reach complete antirust treatment, but be fitted with a rubber sheet gasket below the metallic shim of general existing packing ring, and offer an open-work in the middle of metallic shim and rubber sheet gasket, and the aperture of metallic shim open-work is larger than the external diameter of screw thread, and the open-work of rubber sheet gasket is recessed shape, cause its screw thread can not touch packing ring open-work, can not ensure that metal gasket and the screw of packing ring conduct electricity simultaneously, and allow coating coated together.
Model utility content
The deficiency of not contact phenomena is easily there is in order to overcome existing screw and packing ring, the utility model provides a kind of screw packing ring, this screw packing ring is not only equipped with the pointed fastening part of triangle at packing ring open-work, structure is simple, and can ensure that packing ring and screw have point of contact, ensure to produce electric conductivity between packing ring and screw.
The utility model solves the technological scheme that its technical problem adopts: a kind of screw packing ring, packing ring is made up of metallic shim and rubber sheet gasket, it is characterized in that: described rubber sheet gasket is located at the below of metallic shim, an open-work is offered in the middle of metallic shim and rubber sheet gasket, the open-work of metallic shim and rubber sheet gasket centre is radially equipped with the pointed fastening part of multiple triangle, and the length of fastening part is the 5-10% in open-work aperture, and the internal diameter between fastening part is greater than the internal diameter of screw thread, and be less than the external diameter of thread.
The beneficial effects of the utility model are because offer an open-work in the middle of metallic shim and rubber sheet gasket, the open-work of metallic shim and rubber sheet gasket centre is radially equipped with the pointed fastening part of multiple triangle, and fastening part is canine tooth shape, its fastening part is made to be only limited to the thread localized contact of front end and screw, to effectively reduce the damage of thread, and the metallic shim of packing ring and screw are all metal material, arbitrary canine tooth shape fastening part of metallic shim is only needed to contact with screw, just can make tool conductive effect between packing ring and screw, when making screw carry out powder rust proof paint, can uniform adsorption on the surface of packing ring and screw.

Embodiment
Embodiment of the present utility model is, as shown in the figure:
Embodiment 1, a kind of screw packing ring, packing ring 30 is made up of metallic shim 31 and rubber sheet gasket 32, it is characterized in that: described rubber sheet gasket 32 is located at the below of metallic shim 31, an open-work 33 is offered in the middle of metallic shim 31 with rubber sheet gasket 32, the open-work 33 of metallic shim 31 and rubber sheet gasket 32 centre is radially equipped with the pointed fastening part of multiple triangle 34,35, and the length of fastening part 34,35 is 8% of open-work 33 aperture, and the internal diameter b between fastening part 34 is greater than the internal diameter B of screw 20 thread 21, and be less than the outer diameter A (as shown in Figure 3) of thread 21.
When screw 20 is screwed into by packing ring 30 (as Fig. 2, shown in 3), because open-work 33 ring of metallic shim 31 and rubber sheet gasket 32 establishes multiple fastening part 34, 35, and fastening part 34, internal diameter b between 35 is greater than the internal diameter B of screw 20 thread 21, be less than the outer diameter A of thread 21, the fastening part 34 of metallic shim 31 is made to be fastened on the thread 21 of screw 20, because of its fastening part 34, the length of 35 is the 5-10% in open-work 33 aperture, and fastening part 34, 35 in canine tooth shape, make its fastening part 34, 35 thread 21 localized contact being only limited to front end and screw 20, to effectively reduce the damage of thread 21, and the metallic shim 31 of packing ring 30 and screw 20 are all metal material, arbitrary canine tooth shape fastening part 34 of metallic shim 31 is only needed to contact with screw 20, just can make tool conductive effect between packing ring 30 and screw 20, when making screw 20 carry out powder rust proof paint, can uniform adsorption in packing ring 30 with on the surface of screw 20.
