Embodiment

Fig. 1 illustrates the tripod head 1 that is configured to ball-joint head, comprises the fast fixture 2 for unshowned optical instrument, for example photographic camera of screwing on.The ball-joint consisting of movable joint ball 11 and movable joint nest 12 of tripod head 1 makes optical instrument and make the optical instrument can be around two orthogonal clinoid deflections around 360 ° of pivot axis.In addition ball-joint allows from 90 ° of vertical line deflections in definite position.In addition whole tripod head 1 can be around 360 ° of another pivot axis, and for example panorama rotation (Panoramaschwenk) is possible thus.The cylindrical fixed element 13 that comprises tapped hole 13g extends radially out from movable joint ball 11.Tapped hole 13g is configured to through hole, and this through hole is also through movable joint ball 11 and only have screw thread at the upper curtate of this through hole.But also can set, tapped hole 13g is configured to tapped blind hole.

Movable joint ball 11 has the mounting hole 11m extending by movable joint ball center and arrange perpendicular to the longitudinal axis of fixed element 13.Mounting hole 11m is provided for receiving inner hexagon spanner 17, as further described in Figure 4 and 5 below.

Tripod head 1 can for example be arranged in Fig. 1 on unshowned tripod by means of tripod screw.By using tripod screw that tripod head is installed, it is important theme of the present utility model.Below for being shown in different embodiment in each figure in more detail to its explanation.

If Fig. 1 is for as shown in the embodiment who illustrates there, shown in the situation that on fast fixture 2, by means of fastening device, be detachably fixed for receiving the clamping plate 3 of optical instrument.The attachment screw 21 being screwed in tapped hole 13g passes fast fixture 2, and this attachment screw is detachably connected in fast fixture 2 fixed element 13 of tripod head 1.As found out in Fig. 2 and 3, from the annular end face of fixed element 13, protrude two mutual opposed fixing pin 13s, described fixing pin embeds in each corresponding fixed air gap of fast fixture 2 and forms and reverses stopper.The end face of the bottom side of same tripod head 1 has each fixed air gap 18 similarly forming, so that tripod head 1 can be arranged on tripod to anti-torsion, this tripod has each corresponding fixing pin (see figure 5).

On the terminating set 1f of the bottom side of tripod head 1, acceptor 14 is set.In this acceptor, form the columniform receiving space 14a for inner tripod screw 15.Tapped hole 16 is through receiving 14a bottom surface, space, and inner tripod screw 15 can be screwed in this tapped hole.Receive space 14a to be open upwards, thereby inner tripod screw 15 when being installed, tripod head 1 can inserting and receive in the 14a of space.

Inner tripod screw 15 is configured to threaded stem, and it comprises the threaded sections 15g of bottom side, with respect to bar 15s and the ailhead 15k of threaded sections 15g indentation.Conical ailhead 5k forms has interior hexagonal 15i, inner hexagon spanner 17 can insert (see figure 5) in this interior hexagonal.The length of bar 15s is greater than the length of tapped hole 16, thereby threaded sections 15g stretches out in the bottom surface of tripod head 1 and can in tapped hole 16, rotate freely when inner tripod screw 15 is screwed into completely.

Via inner tripod screw 15, tripod head can be arranged on tripod.But by selecting also likely, utilize the outside tripod screw arranging on tripod to be fixed on tripod tripod head 1.In this case, inner tripod screw 15 is arranged in the position of upwards tightening in tapped hole 16, as shown in Figure 5 in receiving space 14.Unshowned in Fig. 5, for tripod head being fixed on to tripod screw on tripod, outside, can be screwed into from outside tapped hole 16.

Figure 4 and 5 are at tripod head 1 shown in the primary importance of movable joint ball 11, in this primary importance, even also can carry out the installation of tripod head 1 by means of inner tripod screw 15 when clamping plate 3 are loaded onto.

As shown in Figure 4, movable joint nest 12 has for receiving 12a，Gai space, fixed element 13 space to form like this, and the longitudinal axis of the fixed element 13 arranging in receiving portion is parallel to the bottom surface of tripod head 1 and extends.In Gai position, movable joint ball 11 rotates this degree around this longitudinal axis now, until the longitudinal axis of mounting hole 11m is in alignment with the longitudinal axis of tapped hole 1b, inner tripod screw 15 can be screwed in this tapped hole 16.Then inner hexagon spanner 17 can be introduced in the interior hexagonal 15i of inner tripod screw 15 by mounting hole 11m.Two end section of mounting hole 11m coning expand, to make the introducing of inner hexagon spanner 17 become easy.

Screwing in position shown in Fig. 5, inner tripod screw 15 is arranged in the receiving space 14a of tripod head 1 completely and can be placed in screwing in position shown in Fig. 1 and 2 by means of inner hexagon spanner 17.

For tripod head 1 is installed, movable joint ball 11 also can be placed in the second place shown in Fig. 1 and 2 by means of inner tripod screw 15, in this second place, longitudinal axis through the longitudinal axis of the tapped hole 13g of fixed element 13 and movable joint ball 11 in alignment with tapped hole 16, inner tripod screw 15 can be screwed in this tapped hole 16.

Fig. 6 to 9 illustrates the tripod head 1 of the movable joint head that is configured to three-dimensional, comprises integrated fast fixture 2, for unshowned optical instrument for example the clamping plate 3(of vidicon camera see Fig. 8 and 9) can pack this fast fixture 2 into.Tripod head 1 has three chain connection portions, that is the lower chain connection 1u of portion, the middle chain connection 1m of portion and upper hinge joint 1o, and the rotation axis of described each chain connection portion is mutually vertical.The lower chain connection 1u of portion is configured to and can clamps by means of knob 1d.On the middle chain connection 1m of portion and on upper hinge joint 1o, handle 1s is set, described handle can be realized the sensitive deflection around corresponding rotation axis.

The acceptor 14 of the axle journal that is configured to the lower chain connection 1u of portion is set on the terminating set 1f of the bottom side of tripod head 1, in this acceptor, is configured for the receiving space 14a of inner tripod screw 15.The terminating set 1f of bottom side and acceptor 14 are integrally formed formula in the embodiment shown in Fig. 6 to 9.Receive space 14a to be open upwards, so that the tripod screw 15 of inside can insert in receiving space 14a when tripod head 1 is installed.After installing, by cover plate 14d, cover and receive space 14a.Cover plate 14d has the mounting hole 11m at center, and as described further below, screwing tool can be introduced by this mounting hole.The diameter of mounting hole 11m is less than the maximum diameter of inner tripod screw 15 and is greater than the diameter of the screwing tool that can introduce through hole 11m.

Inner tripod spiral shell is followed closely mutually 15 and is configured to threaded stem, comprises the threaded sections 15g of bottom side, with respect to bar 15s and the ailhead 15k of threaded sections 15g indentation.Conical ailhead 15k forms to be had interior hexagonal 15i, inner hexagon spanner 17 can insert in this interior hexagonal (to see Fig. 9,8).The length of bar 15s is greater than the length of tapped hole 16, thereby threaded sections 15g stretches out in the bottom surface of tripod head 1 and can in tapped hole 16, rotate freely when inner tripod screw 15 is screwed into completely.

Correspondingly, as in the embodiment of above-mentioned Fig. 1 to 5, in the embodiment of the movable joint head with three-dimensional of Fig. 6 to 9, also likely, replace tripod head 1 being fixed on tripod via the outside tripod screw arranging on tripod via inner tripod screw 15.In this case, inner tripod screw 15 is arranged on and receives in the 14a of space, as shown in Figure 8.

Screwing in position shown in Fig. 8, inner tripod screw 15 is arranged in the receiving space 14a of tripod head 1 completely.Via the screwing tool that is configured to inner hexagon spanner 17, can adjust tripod screw 15.In the interior hexagonal of inner hexagon spanner 17 through the ailhead 15k of mounting hole 11m and embedding tripod screw 15.When rotating inner hexagon spanner 17, tripod screw 15 is screwed in tapped hole 16, until threaded sections 15g from tapped hole 16 out, as shown in Figure 9.Advantageously, tripod head 1 has been arranged on tripod and via inner tripod screw 15 and has been fixed on tripod at this.
