CN2392941Y - Reliable positioning locking ring - Google Patents

Abstract

The utility model relates to a locking ring. A thinner shell pipe is formed on one end of the locking ring, a cap head with a larger diameter is formed on the middle end, and a screw hole is arranged in the middle end; in addition, the outer edge near the cap head is provided with more than one convex positioning strips which are separated. Accordingly, the locking ring can be reliably fixed to an object to be fixed, and the simple structure.

Description

The locking ring of reliable location

The utility model relates to a kind of locking ring.

At present, the Taiwan patent gazette is announced " bolt locking ring structure " patent case No. 296756, is provided with the cap head by a locking ring one end, and the other end forms the shell wall than minimal thickness, this cap head is provided with the convex body that protrudes towards the shell wall direction, and shell wall forms less thickness, outside the internal thread of the internal thread that locking encircles, can be by the avulsion reflexed, this locking ring is transferred when knocking in object, and the convex body of cap head is tufted in the object, yet, because this convex body only hammers into external surface of objects, its locating effect is not good.

In view of this, the purpose of this utility model provides a kind of locking ring of reliable location, and it can increase and the engaging force that is fixed on the object, to reduce slide relative.

The purpose of this utility model is achieved in that a kind of locking ring of reliable location, the one end forms thin package, and in an end form larger-diameter cap head, and in this end, have screw, it is characterized in that: near having one or more the protrusion positioning strip that separates on the outer rim of cap head.

Described positioning strip is parallel to package and screw central axis.

Described institute position bar is 4.

Described package is provided with several opening slots that separate.

Because adopt such scheme: can be fixed on reliably on the object that is fixed, structure is also simple.

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: 22 combined 3 on locking ring 1 cap head 11 packages 12 screws 13 positioning strips 14 opening slots 15 fixtures 2 holes 21 bolts

The locking ring 1 that first embodiment is made by metal material, the one end is provided with larger-diameter cap head 11, and the other end forms thin package 12, locking ring 1 internal diameter is provided with screw 13 again, outer path position near cap head 11 is provided with (bar) above positioning strip 14 together in addition, as shown in Figure 1, this positioning strip 14 is 4 (the most suitable), and this positioning strip 14 is parallel to locking ring central axis.

As shown in Figure 2, when locking ring 1 desires to be fixed use, locking ring 1 can be set in the hole 21 of fixation 2 by package 12 positions, and positioning strip 14 is entered in hole 21 with external force, and the reflexed and the fixture 2 that package 12 are expanded in modes such as riveteds amplexiform, as shown in Figure 3, borrow bolt 22 to screw in screw 13 again, can be with another combined 3 combination, when locking ring 1 was combined in the hole 21, this positioning strip 14 was engaged on the inner tubal wall in this hole and produces the location.

As shown in Figure 4, when locking ring 1 is fixed in the fixture 2, the positioning strip 14 of locking ring 1 promptly can and fixture 2 become between firm location attachment and the two and have good anti-slip effect (not having sliding friction).

As shown in Figure 5,,, on this package 12, offer several opening slots 15, make package 12 easily by reflexed and amplexiform on fixture 2 (as shown in Figure 6) for package 12 parts that make locking ring 1 are easy to expand reflexed in second embodiment.

Between locking ring of the present utility model and fixture, because the setting of positioning strip is arranged, so between the hole of locking ring and fixture, form the combination of non-positive toroidal, this positioning strip has the rotation that stops the two, therefore has good anti-slip effect.
