Abstract

The utility model discloses a device for spherical locking of photography hathpace, which comprises a ball, a spheriform washer, a locking blocks and a knob with a screw, wherein, the ball and the spheriform washer are arranged on the locking blocks, the two locking blocks stacks together from top to bottom with their lateral respectively a slant cooperated, a thread hole cooperated with the knob with the screw is arranged on the ektexine of the locking blocks in the distal; in addition, a washer used to separate the hathpace is arranged under the locking block. The utility model locks the ball tightly by using two locking blocks which are tightened together, at the same time, separates the base of the hathpace by washer, in this way, even the ball is tightened, the moving of the base of the hathpace is not affected and very convenient to use; and the setting of the damp fine-tuning parts allow users to adjust ball needed damp to achieve the satisfactory effect.

Description

A kind of spheroid locking device of photography holder

Technical field:

The utility model relates to the photographic goods technical field, especially relates to a kind of spheroid locking device of photography holder.

Background technology:

The photography holder of seeing in the market, it is used to prevent that camera from mainly containing following three kinds at the moving spheroid locking device of the follow-up reforwarding of locking: (1), see shown in the accompanying drawing 1, first kind of spheroid locking device is the knob 01 and 02 that two symmetries are set on shell, knob 01 and 02 screw rod 011,021 front end are conical surface shape, and cooperate with the latch segment 03 of spheroid packing ring 20 belows, when turning knob 01 and 02, can make latch segment 03 move upward, thus locking spheroid 10.(2), see shown in the accompanying drawing 2, second kind of spheroid locking device is that knob 01 is set on shell, screw rod 011 front end of knob 01 is a conical surface shape, what it was different with first kind of spheroid locking device is, spheroid 10 is by the directly supporting of the conical surface 101 of The Cloud Terrace 100 bases upper ends, and at the waist of The Cloud Terrace 100, is provided with the latch segment 04 with the cone match of screw rod 011 front end, when turning knob 01, The Cloud Terrace 100 and latch segment 04 are moved upward together and pin spheroid 10.(3), see shown in the accompanying drawing 3, the third spheroid locking device is that the left and right sides is provided with two latch segments 05 and 06 outside spheroid 10, latch segment 05 and 06 middle part all with screw rod 011 threaded engagement of knob 01, latch segment 05 and 06 lower end then engage mutually with The Cloud Terrace base 100, when turning knob 01, latch segment 05 and 06 move toward one another on screw rod 011, thus clamp spheroid 10.

Above-mentioned several spheroid locking device respectively has its relative merits, and wherein, first kind of spheroid locking device adjusted the poor effect of spheroid damping; And the basic function of just not adjusting the spheroid damping of second kind and the third spheroid locking device, and in a single day be locked when spheroid, then the The Cloud Terrace base also can't rotate, and this has brought some inconveniences to the cameraman.

The utility model content:

The purpose of this utility model is to provide a kind of new photography holder spheroid locking device, even its structure makes that The Cloud Terrace also still can rotate after spheroid is locked.

For achieving the above object, the utility model comprises spheroid, spheroid packing ring, two latch segments and the knob that has screw rod, wherein, spheroid and spheroid packing ring are positioned on the latch segment, two latch segment upper and lower sleeves stack, its outside has an inclined-plane that cooperatively interacts respectively, on the latch segment outer wall of lower end, offers the threaded hole that cooperates with the screw rod of knob; In addition, the latch segment lower end is provided with a back-up ring that The Cloud Terrace is separated.

Between the latch segment of spheroid packing ring and upper end, be provided with a spheroid damping trimming part, the upper end of this damping trimming part has a conical surface that cooperates with the spheroid packing ring, the lower end then have one with the connecting pipe of latch segment threaded engagement.

Be plane and fit together mutually over against the lower end latch segment inwall of threaded hole and upper end locking piece outer wall.

The beneficial effects of the utility model are: two latch segments that are set-located were locked spheroid about it adopted, and simultaneously, utilized back-up ring that the The Cloud Terrace base is separated, and like this, even spheroid is locked, did not also influence the rotation of The Cloud Terrace base, and are very easy to use; And the setting of damping trimming part then can allow the user regulate the spheroid damping as required, makes it reach perfect condition.

Embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in accompanying drawing 4 and the accompanying drawing 5: the utility model comprises spheroid 10, spheroid packing ring 20, two

latch segments

30 and 40 and the knob 50 that has screw rod 51.Wherein, spheroid 10 and spheroid packing ring 20 are positioned on

latch segment

30 and 40, and

latch segment

30 and 40 upper and lower sleeves stack, and its outside has an inclined-plane that cooperatively interacts 301,401 respectively, on latch segment 40 outer walls of lower end, offer the threaded hole 41 that cooperates with the screw rod 51 of knob 50.When turning knob 50, screw rod 51 promotes latch segment 30 and moves upward along inclined-plane 401, thus locking spheroid 10.For the power that makes screw rod 51 promote latch segments 30 actions reaches maximum, be plane and fit together mutually over against latch segment 40 inwalls of threaded hole 41 and latch segment 30 outer walls.In addition, latch segment 40 lower ends are provided with a back-up ring 60 that The Cloud Terrace base (not shown) is separated, and like this, after spheroid 10 lockings, the The Cloud Terrace base still can rotate.

Between spheroid packing ring 20 and latch segment 30, be provided with a spheroid damping trimming part 70, the upper end of this damping trimming part 70 has a conical surface 71 that cooperates with spheroid packing ring 20, the lower end then have one with the connecting pipe 72 of latch segment 30 threaded engagement.When rotary damping trimming part 70, damping trimming part 70 moves upward together with spheroid 10 and spheroid packing ring 20, thereby reaches the effect of fine setting spheroid damping, and is very convenient.
