Description

Nut

Technical field

The utility model relates to a kind of nut.

Background technique

Nut is also called nut, and general nut has many types, has hexagon nut, has round nut, square nut etc.Nut is the part got up by machinery compact siro spinning technology, together with being screwed in bolt or screw rod by the screw thread of inner side, be used for playing the role of fastening, all manufacture machinery must a kind of element according to the difference of material, be divided into several large types such as carbon steel, stainless steel, non-ferrous metal (as copper).Because a lot of nut exposes in atmosphere, of long duration to get rusty easily, be particularly arranged on outdoor nut, often stand to drench with rain, the joint of nut and bolt gets rusty easily, and causes that nut is stubborn not to get off.

Model utility content

For the deficiency that prior art exists, easy-off nut after the purpose of this utility model is to provide one to get rusty.

For achieving the above object, the utility model provides following technological scheme: a kind of nut, comprise nut body, described nut body comprises the tapped hole at center, described nut body arranges main aperture and some secondary orifices, described main aperture extends to outside nut body, and the madial wall that described some secondary orifices are arranged on tapped hole is communicated with main aperture.

By adopting technique scheme, after nut to be connected with bolt and to get rusty, when needing nut to disassemble, lube oil injection in main aperture, lubricant oil flows to secondary orifices from main aperture, secondary orifices is arranged on the madial wall of tapped hole, lubricant oil can flow to the joint of nut and bolt from secondary orifices, thus makes nut occur to loosen, due to the lubrication of lubricant oil, frictional force between nut and bolt reduces, and nut is easily screwed down.

The utility model is set to further: arrange the inserted link that cross section size is identical with main aperture in described main aperture, and described inserted link extends to outside main aperture.

By adopting technique scheme: inserted link one can play the effect strengthening nut intensity, also by inserted link, lubricant oil can be compressed into main aperture on the other hand, because nut and bolt coordinate closely, inserted link is inserted main aperture and form an airtight space, a power can be applied to a joint all directions when being entered in main aperture by lubrication pressure, this power is the pressure that lubricant oil is extruded generation, nut and bolt is made to occur to loosen, nut is made easily to screw down further, bar extends to outside main aperture and facilitates inserted link to take off, and puts into lubricant oil.

Model utility is set to further: described nut is iron, and described inserted link is that magnet is made.

By adopting technique scheme, cap is iron, and inserted link is that magnet is made, and by magnet and iron adhesive, inserted link does not need other structure to fix, and structure is simple.

The utility model is set to further: described main aperture is arranged on one of them end face of nut body, and the cross section of described main aperture is regular hexagon.

By adopting technique scheme, can drive cap rotation by rotating inserted link, the cross section of main aperture is regular hexagon, and inserted link rotation can not occur.

The utility model is set to further: described inserted link end connects push-and-pull block.

By adopting technique scheme, push-and-pull block facilitates inserted link to push or takes out.

The utility model is set to further: described secondary orifices threadingly aperture is evenly arranged to circumference.

By adopting technique scheme, secondary orifices threadingly aperture to circumference evenly arrange lubricant oil distribute more evenly, make nut be more prone to back-out.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model nut;

Fig. 2 is the side view of the utility model nut;

Fig. 3 is the sectional view of A-A in Fig. 2.

Reference character: 1, nut body; 11, tapped hole; 12, main aperture; 13, secondary orifices; 2, inserted link; 21, push-and-pull block.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model nut embodiment is described further.

As shown in Figure 1 to Figure 3, a kind of nut, comprise nut body 1, nut body 1 is square block, nut body 1 comprises the tapped hole 11 at center, nut body 1 arranges main aperture 12 and some secondary orifices 13, main aperture 12 extends to outside nut body 1, the madial wall that some secondary orifices 13 are arranged on tapped hole 11 is communicated with main aperture 12, secondary orifices 13 is circular port, secondary orifices 13 can each be communicated with main aperture 12 alone, also can wherein at least one secondary orifices 13 be communicated with main aperture 12, be interconnected between secondary orifices 13, as long as ensure that lubricant oil can flow out to the joint of nut and bolt from each secondary orifices 13, in the present embodiment, main aperture 12 arranges two, and be symmetricly set on two diagonal angles of nut body 1, symmetrical arrangement is stablized, and facilitate the interpolation of lubricant oil, this joint refers to the internal thread of nut and the outside thread mating area of bolt, preferred secondary orifices 13 threadingly hole 11 radial direction is evenly arranged with circumference, main aperture 12 is arranged on one of them end face of nut body 1, the cross section of main aperture 12 is regular hexagon, arranging the cross section identical with main aperture 12 size in main aperture 12 is orthohexagonal inserted link 2, inserted link 2 extends to outside main aperture 12, inserted link 2 end connects push-and-pull block 21, push-and-pull block 21 is one-body molded with inserted link 2, intensity is high, push-and-pull block 21 is hemisphere, inserted link 2 adopts magnet to make, nut body 1 adopts iron.

The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
