Specific embodiment

It is below with reference to the accompanying drawings and in conjunction with the embodiments, next that the present invention will be described in detail.

Embodiment 1

Referring to figs. 1 to Fig. 4, the present embodiment provides a kind of locking device, including tight split nut 1 and fixing pipe 2, tight split nuts 1 and fixing pipe 2 all have axially extending bore, tight split nut 1 passes through the external thread bolt connection of its internal screw thread and 2 upper end of fixing pipe, Gu Pipe 2 is determined circumferentially arranged with multiple flutings 5, and fluting 5 is axial setting, is extended downwardly from the top of fixing pipe 2, in the present embodiment In, fluting 5 is three and is uniformly distributed in the periphery of fixing pipe 2, and 5 bottom end of slotting is equipped with a protrusion 51, inlays on fluting 5 There is support movable block 6, the upper surface of support movable block 6 is horizontal support surface 61, and the lower end of support movable block 6 has upward circle Arc opening 62, circular arc opening 62 are placed in the protrusion 51 of 5 bottom ends of fluting, and protrusion 51 can be the circle agreed with circular arc 62 phases of opening The inner end of arc protrusion, support movable block 6 has the first limiting section 63, and the first limiting section 63 is placed in the axially extending bore of fixing pipe 2, Support the outer end of movable block 6 that there is inclined surface 64 inside downwards, the outer end of movable supporting block 6 has the second limiting section 65.

When the locking device is under normal condition, since movable supporting block 6 has inclined surface 64 inside downwards, activity Supporting block 6, which is located at, has the direction being inclined outwardly in the fluting 5 of fixing pipe 2, the first limiting section 63 is for blocking movable supporting block 6。

The locking device is used for the table top 4 with aperture 3, first by movable supporting block 6 toward fixing pipe 2 when being put into hole Inside promotes, and then movable supporting block 6 moves downward, and is caught in aperture 3 gradually using inclined surface 64 inside downwards, when activity is propped up Bracer 6 tightens tight split nut 1 completely into 4 lower section of table top, and the circular arc opening 62 of 6 lower end of movable supporting block is located at 5 bottoms of fluting In the protrusion 51 at end, the horizontal support surface 61 of movable supporting block 6 will be close to the bottom of table top 4, so that fixing pipe 2 is fixed on platform On face 4.

The outside of tight split nut 1 has external screw thread, and product (such as faucet 7) passes through the outer spiral shell of its internal screw thread and tight split nut 1 Line is spirally connected lock in fixing pipe 2.

From the above, it can be seen that structure is simple using locking device provided by the embodiment of the utility model, design is closed Reason, it is easy for installation without installing fixture nut under platform, convenient for product being mounted and fixed to manpower or utensil can not be got at Place, and fastening effect is good, is suitable for large-scale promotion application.

Embodiment 2

Referring to Fig. 5 to Fig. 9, the present embodiment provides a kind of locking devices, compared with Example 1, the difference is that, fluting 5 both ends are all closed, and have the through-hole 52 passed through for the first limiting section 63 in the upper end of fluting 5, movable supporting block 6 can be from through-hole In 52 insertion flutings 5.

1 bottom end external rings of tight split nut in the present embodiment are equipped with pedestal 14, are located on pedestal 14 outside tight split nut 1 It is successively equipped with first boss 11, second boss 12 and third boss 13, first boss 11, second boss 12 and from top to bottom Three boss 13 all have the notch 17 to align, and the bottom end of faucet 7 has one axially grooved 71, and axially grooved 71 bottom end is equipped with Internal projection 72, the notch 17 that internal projection 72 aligns from first boss 11, second boss 12 and third boss 13 enter, and are caught in bottom In the first conduit 15 between seat 14 and first boss 11, carry out tentatively fixed；

It is equipped with screw hole 73 in the second conduit 16 that the side of faucet 7 corresponds between second boss 12 and third boss 13, Screw hole 73 is screwed in by screw 74 and resists the second conduit 16, is fixed again.

From the above, it can be seen that simple for structure, design is closed using locking device provided by the embodiment of the utility model Reason, faucet 7 are effectively fixed on tight split nut 1 by secondary fixation, install convenient, and good fixing effect.

The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
