Description

The jam nut of band cap

The utility model relates to a kind of jam nut, particularly a kind of jam nut with cap.

With general traditional CAP NUTS structural design, mainly be set as Fig. 5, shown in 6, the sealed outside in nut body 30, cooperate a cap 31 as the solid welding combination, form the structure of a CAP NUTS, and can find out not have any locking design by its total at all, from not conforming to locking sealed needs, for in response to locking sealed needs, locking CAP NUTS just is developed, and with general common locking CAP NUTS design, usually directly be main structure body with the jam nut, cooperate cap in conjunction with forming a CAP NUTS shape, because traditional jam nut price is higher, and inner the need in advance of one end closed accessory filling processing in case uncage, common used material has nylon ring or steel disc, no matter being nylon ring or steel disc, it all needs moulding in advance, again with the punching out integrated positioning, owing to mould on the type of making and the material all simpler and easy with nylon ring, cost is lower, the nylon ring outer end of thought filling, it is winding cap one end, because of its plastic material is unsuitable for welding operation, to make inner nylon ring sclerosis cracked because of welding high heat, so when doing the CAP NUTS making with the nylon jam nut, usually cap is extended the sealed base that is coated to nut, making with locking CAP NUTS, it needs to do main body with built-in steel disc formula jam nut usually, right in the locking nut of class steel disc locker, its construction cost is higher, because of the processing cost of its monolithic add put rivet clasp make need accurate, because of locating if fail really steel disc to be given rivet clasp, with possibility because with the effect of transferring its original locking locker of forfeiture certainly of locking the bar tool, so higher relatively in the nut acquisition cost of integral body.

The purpose of this utility model is to provide a kind of jam nut with cap, make cap and nut be combined into a firm structure, and cap and anti-release member and nut can be distinguished independent processing and fabricating, with more convenient continuous automatic production, manufacture cost is reduced.

The utility model provides a kind of jam nut with cap, comprises a nut body, a cap and anti-release member; It is characterized in that: this cap is in several dististyles that bend inwards of branch moulding and the outside dististyles that bends such as its ring bottom surfaces, this anti-release member is placed in the peristoma of this cap and is clamped by the dististyle that bends inwards of cap, establish of the dististyle clamping of the bulge loop of a bending in the apical margin of nut body, cap and nut body secure bond are integral the outside bending of cap.

The jam nut of described band cap is characterized in that: this anti-release member can be anti-loosing slice or anti-DNA releaxed circular DNA.

Effect of the present utility model is: the jam nut of band cap of the present utility model, on its shaping structures, when cap 20 punch formings, can be directly and anti-release member 21 do one and be combined into solid memder, mutually combine with nut body 10 again, cap 20 is one-body molded with anti-release member 21 punching out, can conveniently do continuous processing by special-purpose machines and tools, has the saving of labor and production safety is rapid, significantly reduce the effect of manufacture cost, it need not to do with nut body the sequence limit of progressive forming, and with the location of anti-release member 21, will be because of the packing of cap 20 recessed curved arcs, after dististyle 22 invaginations insert and put, the anti-release member 21 of sheet or ring-type can be clamped really, and the dististyle 22 that cooperation outwards bends, then can be convenient to nut body 10 on set bulge loop 11 do rivet clasp and clamp, and by the cap 20 outer dististyles 22 that stretch out, do not contact with anti-release member 21, cap 20 also is convenient to carry out solid welding with 10 of nut bodies and is combined, anti-release member 21 for interior dress then can not produce direct influence, the cost of material of nut body 10 is reduced relatively, promptly can use with the general not nut body 10 of the locking design of tool, cost of production is significantly reduced, locking effect is further guaranteed.

For further understanding structure characteristic of the present utility model and purpose, below describe in detail as the back with embodiment's conjunction with figs.:

The jam nut of band cap of the present utility model, please cooperate shown in Fig. 1～3, the members such as anti-release member 21 that mainly contain a nut body 10 and a cap 20 and interior dress one, wherein nut body 10 is on sealed exterior edge face, cooperate to establish and stay a bulge loop 11 that protrudes, make bulge loop 11 inner edges form a shallow flat putting groove 12, (its semi-finished product that can be directly do not load anti-release member 21 with general jam nut fill usefulness), and cap 20 is according to the needs that use, punching out is become disk or ball shape, several dististyles that bend inwards 22 of branch moulding such as its bottom edge and the dististyle 22 that outwards bends, cooperate this anti-release member 21 to be placed in the peristoma of this cap 20 and clamped by the dististyle that bends inwards 22 of cap 20, establish of dististyle 22 clampings of the bulge loop 11 of a bending in the apical margin of nut body 10, cap 20 and nut body 10 secure bond are integral the outside bending of cap 20.

It can be plastic anti-loosing slice or anti-DNA releaxed circular DNA 212 anti-release member 21, as shown in Figure 4, directly be presented to the spill oral area of cap 20, itself and cap 20 are installed to be combined into one, and as shown in Figure 4, when in case DNA releaxed circular DNA 212 fillings when assembling, because the compressed characteristic of its plasticity, because of the cap 20 recessed tapering type designs of curved arc, can make the location of the anti-release member 21 that charges into safer firm, and the dististyle 22 that cap 20 outwards protrudes, just for after in the putting groove 12 that falls that is presented to nut body 10 apical margins, make things convenient for outer rim bulge loop 11 inwardly wash off fashionable, whole cap 20 structures of clamping synchronously, constitute the jam nut of a complete band cap, lock Shi Kesuo for screw rod 23 and support to fix and push against the purpose that reaches simple and easy locking operation.
