Abstract

The utility model relates to a hook with long service life, high reliability and convenient use, comprising a front gland, a rear gland and a hanging rod, wherein a sphere is arranged at the inner end of the hanging rod, and the outer end extends out of a shell formed by the front gland and the rear gland, and a clamp is sleeved on the outer surface of the sphere, at least one of the two end faces of the clamp is attached to the front gland or the rear gland, and the screw head of a tightening screw of the clamp is exposed outside the front gland or the rear gland.

Description

A kind of hook

Technical field

The utility model relates to a kind of hook, particularly a kind of hook that can be installed on the wall.

Background technology

The hook that is used at present to hang article such as audio amplifier in the household can be the direct nail of nail on wall, perhaps on wall, fix universal hook with screw, this universal hook comprises peg, preceding gland and rear pressing cover, wherein peg the inner is provided with spheroid, on the forward surface of front and back gland, offer respectively less than sphere diameter and the pressure ring or the indent that match with spherome surface, the front side of preceding gland has through hole, the through hole of peg leading portion on preceding gland stretches out, the front and back gland screws down the back pressure ring or indent is clamped Sphere orientation between the gland of front and back and by the front and back gland, spheroid can be rotated with respect to the front and back gland, at last universal hook is fixed on the wall and can uses with screw, during use, firmly stir peg and spheroid is overcome with the frictional force of pressure ring rotate, thereby change the direction of peg; Because universal hook can change the direction of peg, so be used to hang audio amplifier treat when needs are regulated the article of direction comparatively convenient, but the shortcoming of this universal hook be the life-span short, reliability is low, reason is after the direction through repeatedly changing peg, can produce wearing and tearing between spheroid and the pressure ring, thereby reduce the frictional force between spheroid and the pressure ring, at this moment, hang over audio amplifier on the hook and fall from the high-altitude easily and cause danger; And in use, the article that are hung on the hook are subjected to bigger external force a little, and hook will be swung, and the user must readjust the hook direction, and after repeatedly adjusting, spheroid or front and back gland will produce wearing and tearing and cause frictional force between the two to descend.

Summary of the invention

The purpose of this utility model is the problem that life-span is short, reliability is low that exists in the existing universal hook in order to solve, and the hook that a kind of life-span is long, reliability is high, easy to use is provided.

The purpose of this utility model is achieved in that a kind of hook, comprise preceding gland, rear pressing cover and peg, peg the inner is provided with spheroid, stretch out outside the shell of preceding gland and rear pressing cover formation the outer end, outer surface at described spheroid is with anchor ear, gland or rear pressing cover before having at least an end face to touch in two end faces of this anchor ear, and the screw terminal of the parbuckle screw of this anchor ear exposes to outside preceding gland or the rear pressing cover.During use, unclamp the parbuckle screw of anchor ear with screwdriver, at this moment, the function of hook is identical with existing hook, and the direction that can regulate peg is to correct position, then parbuckle screw is tightened, make anchor ear hug the spheroid of peg the inner, and the front end face of anchor ear or rear end face be close to before gland or rear pressing cover, so even there is external force to act on the peg, spheroid can not rotate yet, thereby reaches the purpose of locking peg.

Described hook can have counterbore on the rear end face of preceding gland, described anchor ear is placed in this counterbore.

Described hook, the position corresponding to described screw terminal on preceding gland or rear pressing cover has side opening, and screw terminal exposes to outside the shell by this side opening.

Described hook can have counterbore at the rear end face of preceding gland, also has counterbore at the front end face of rear pressing cover, and the counterbore of forward and backward gland surrounds cannelure, and anchor ear is placed in this cannelure.

Owing to adopted technical scheme described in the utility model, relative positioning between peg and the shell is to realize by the anchor ear that can regulate degree of tightness, hang up article at ordinary times after, even under external force, hook can not rotate with respect to shell yet, and its reliability height, life-span are long; And the screw terminal of regulating the anchor ear degree of tightness exposes to outside the shell, uses the utmost point convenient.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional exploded view of an embodiment of hook described in the utility model.

Fig. 2 is the cut-away view after Fig. 1 embodiment fits together.

Fig. 3 is the stereogram after Fig. 1 embodiment fits together.

Fig. 4 has taken the schematic diagram behind the anchor ear away among Fig. 2.

Among the figure 1, preceding gland, 11, through hole, 12, side opening, 2, peg, 21, spheroid, 4, anchor ear, 41, screw, 42, nut, 31, counterbore, 32, indent, 3, rear pressing cover, 10, counterbore.

The specific embodiment:

See Fig. 1, described hook, gland 1, rear pressing cover 3 and peg 2 before comprising, peg 2 for L shaped, it innerly is provided with spheroid 21, when installing, left end with peg 2 left ends gland 1 before the rear end of preceding gland 1 is passed through hole 11 and stretched out, anchor ear 4 is entangled spheroid 21 outer surfaces, back the rectifying of gland 1 gets final product before then rear pressing cover 3 being packed into again.The front end of rear pressing cover 3 is provided with the sphere shape indent 32 that the sphere with spheroid 21 matches among Fig. 1, is provided with counterbore 31 at the oral area of this indent 32, also is provided with sphere and the counterbore of pushing down spheroid 21 equally on preceding gland.See Fig. 4, also have counterbore 10 on preceding gland, the counterbore 31 among this counterbore 10 and Fig. 1 on the rear pressing cover surrounds a cannelure, and this cannelure is used for placing the anchor ear 4 of Fig. 1.

Stereogram after present embodiment installs as shown in Figure 3, wherein the side opening 12 of the screw terminal of parbuckle screw on preceding gland exposes to outside the shell, during use, screwdriver stretched into side opening 12 promptly can turn parbuckle screw.

Cut-away view after the hook of present embodiment installs is seen shown in Figure 2, at this moment, anchor ear 4 is positioned at the cannelure (seeing shown in Figure 4) that the counterbore by the counterbore of preceding gland 1 rear end and rear pressing cover 3 front ends surrounds, this cannelure plays position-limiting action to the left and right directions of anchor ear 4, gapped between anchor ear 4 and the spheroid 21, spheroid 21 can rotate, state when unclamping, end is spacing by preceding gland and rear pressing cover about spheroid 21, in case anchor ear 4 is held spheroid 21 tightly, then all limited because of end about anchor ear 4, so spheroid 21 can not rotate, peg 2 also just can not be swung.

Two of anchor ear end faces touch forward and backward gland respectively in the present embodiment, and in fact, gland or rear pressing cover got final product before it only need touch; And anchor ear is arranged on the maximum outside diameter place of spheroid.

Anchor ear described in the utility model also claims pipe collar, is a kind of existing securing member, is used for combustion gas rubber hose coupling place in the actual life more.
