[embodiment]

Embodiment 1

As shown in Figure 1, be the structural representation of the flexible hanging hook assembly of present embodiment.This hanging hook assembly comprises hook 10, fastener 20, bounding means 30 and elastic component 40.Hook 10 comprises the interconnective neck of hook 102 and hook portion 104, and fastener 20 is provided with the receiving hole 202 that holds the neck of hook.The neck of hook 102 passes receiving hole 202, and the free end of the neck of hook 102 is connected with bounding means 30, elastic component 40 be sheathed on the neck of hook 102 and be limited in bounding means 30 and fastener 20 between.

The neck of hook 102 of hook 10 can stretch in receiving hole 202, its maximum outreach is by the length restriction of elastic component 30 and the neck of hook 102 itself, hook portion 104 is stretched out and is tangled weight during use, withstands fastener 20 by bounding means 30 and elastic component 40, prevents to link up with 10 and deviates from; 30 of time spent elastic components do not rebound it, and hook portion 104 and fastener 20 are offseted.

Bounding means 30 can be nut, and the free end of the neck of hook 102 is provided with outside thread, cooperates with the outside thread of the neck of hook 102 by bounding means 30 to be spirally connected.In other embodiment, bounding means 30 also can be integrated structure with the free end of the neck of hook 102.

In the present embodiment, preferred elastic component is a spring.

This hanging hook assembly is to be used for hook weight when photography, operated by rotary motion is in middle pipe 90, as shown in Figure 1, fastener 20 comprises interconnective main body 204 and base 206, main body 204 section ratio bases 206 areas are little, main body 204 is with embedded mode and 90 clampings of middle pipe, and by base 206 opening of middle pipe 90 sealed.

In the present embodiment, cooperate the middle pipe 90 of flat, main body 204 be shaped as flat.As shown in Figure 2, main body 204 sidewalls are provided with shell fragment 208, and shell fragment 208 is provided with projection 210 toward the outer side.In pipe 90 sidewall be provided with hole clipping 902, when main body 204 manage in 90 in embedding, the sidewall of pipe 90 during projection 210 props up, shell fragment 208 curves inwardly, pipe was after 90s during main body 204 entered fully, projection 210 snaps in hole clipping 902, main body 204 and middle pipe 90 are finished clamping.

Be the cooperate schematic representation of hook 10 as Fig. 3 with fastener 20.Link up with 10 L-shapedly, the end of hook portion 104 is provided with the stop hooks 106 of bending in hook 10.Base 206 is provided with the accepting hole 212 corresponding with stop hooks 106, and stop hooks 106 was contained in the accepting hole 212 when hook 10 shrank.

When hook 10 withdrawals, for further facilitating the taking-up of hook 10, the susceptor surface between receiving hole 202 and the accepting hole 212 is a concave arc surface 214., stop hooks 106 is housed in the accepting hole 212, and hook portion 104 exposes to concave arc surface 214, can conveniently point taking-up during use.

Embodiment 2

In the foregoing description, main body 204 is the shape of pipe 90 in cooperating, and its shape also is a flat.In fact the shape of main body 204 also can be other shapes, as circular, square or irregularly shaped etc.

As shown in Figure 4, present embodiment is chosen main body 204 ' cross section for circular, is being connected of convenient and middle pipe 90 ', and main body 204 ' outside is provided with outside thread, can establish internal thread at middle pipe 90 ' inwall, and main body 204 ' and middle pipe 90 ' are spirally connected; Perhaps set up rotation preventing device 80, establish internal thread, main body 204 ' and rotation preventing device 80 are spirally connected, then rotation preventing device 80 is carried out anti-rotation with middle pipe 90 ' and be connected at rotation preventing device 80 inwalls.It is to establish axial notch 802 at rotation preventing device 80 outer walls that preferred anti-rotation connects, and middle pipe 90 ' is provided with inside axial fin 902 ', by the cooperate anti-rotation of groove 802 with fin 902 '.

In the present embodiment, because the cross section of main body 204 ' is chosen for circle, so the position of receiving hole 202 ' (referring to Fig. 5) is set to the central position of offset from body 204 ', so just can easily hook portion 104 ' be placed in the base 206 ' fully, base 206 ' is provided with the cavity 210 ' hook portion 104 ' of holding hook portion 104 ' and just is arranged in this cavity 210 '.

As shown in Figure 5, for the total length that makes the neck of hook 102 ' can shorten and make bounding means 30 can receive in the main body 204 ' as far as possible, make things convenient for other occasion user demands, preferably, in main body 204 ', be provided with the cavity 208 ' that is communicated with receiving hole 202 ', the diameter of cavity 208 ' is greater than the diameter of receiving hole 202 ', and cavity 208 ' forms shoulder hole with receiving hole 202 '.Elastic component 40 1 ends and bounding means 30 offset, and the other end stretches into butt in the cavity 208 '.

As shown in Figure 6, cavity 210 ' sidewall is provided with blind hole 212 ', can be used for accommodating the stop hooks 106 ' of hook 10 '.

The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
