Abstract
The utility model relates to the field of auxiliary apparatus for image picking up and relates to a telescopic tripod which is designed to aim at the impacted locking device of the existing tripod. The utility model is mainly characterized in that a locking screw rod in the locking device is connected with a rotary spanner and is inserted into a movable connector; the empty cavity of a locking block is connected with a locking nut; a locking spring is arranged between the movable connector and the locking block; the movable connector is provided with a rotary gear block; the spiral incline of the rotary gear block is contacted with the incline block of the rotary spanner; the two ends of a relief spring are respectively connected with a spring plug and a spur guard; the spur guard is arranged in the limitation hole of the rotary spanner which is provided with a button; the bottom part of the button is connected with the spring of the button; a guide post is arranged in the limitation hole of the rotary spanner; the two ends of the guide post are respectively butted with the spur guard and the button. The locking device solves the technical problems of adjusting, tightly locking, safety and easy loosing of the tripod and has the characteristics of being reasonably designed, simply operated and tightly locked; besides, the telescopic tripod is suitable for a vidicon and a DV.
Description
Technical field
The utility model relates to a kind of shooting annex equipment field, is a kind of extension tripod.
Background technique
When vidicon camera, DV machine are taken, generally all to use tripod and support, and by tripod to angle of shooting, highly regulate.Most of tripods adopt extending foots to regulate angle of shooting, highly, and its leg is made up of some telescopic pipes, and each leg telescopic adjustment is finished by locking device.But because the design of the locking device of most of extension tripods is different, its locking mode is also different, some locking devices are loose to the degree of blocking of pin pipe, lack safty device, behind fixed tripod angle of shooting, the height, occur easily that the pin pipe skids, the locking device accident is unclamped, cause angle of shooting, highly change, even the situation of damaging apparatus for making a video recording takes place.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned existence, and purpose is to provide a kind of locking mode simple to related domain, and has the extension tripod of safty device, makes it can solve existing tripod locking device and owes perfect technical problem.The purpose of this utility model realizes by the following technical solutions.
A kind of extension tripod is made up of pin pipe, pipe and locking device, and its main points are that the locking screw in the locking device connects rotary spanner, and the cavity that locking screw inserts active connection, locking block is connected with locking nut; Be provided with locking spring between active connection and the locking block; Active connection is provided with rotation gear piece, and the screw inclined plane of rotation gear piece contacts with the ramp blocks of rotary spanner; The relief spring two ends link with spring plug, arming pin respectively, arming pin is inserted the spacing hole of rotary spanner, and rotary spanner is provided with button, and the button bottom connects button spring, guide pillar is inserted in the spacing hole of rotary spanner, and the two ends of guide pillar offset with arming pin, button respectively.
Described locking nut and stop screw offset, and prevent locking nut loosening on the locking block.
The fixedly connected pipe of described locking device, active connection and locking block clamp, and two ends are with the pin pipe respectively.By the degree of tightness of locking device, make active connection up and down, it is up and down to drive pipe, regulates the collapsing length of each pipe, regulates flexible link press span simultaneously, make tripod whole angle, highly change.
Locking device of the present utility model has solved tripod adjusting, tight lock, insurance, easy loosening technical problem, and its general structure design is reasonable, and is simple to operate, tightly locks firm characteristics, is applicable to the adjusting of the support of vidicon camera, DV machine and angle, height.

Embodiment
Mode of execution is example with actual use of the utility model.The locking device of this tripod mainly is made of rotary spanner 3, rotation gear piece 4, locking block 7, arming pin 14.When taking, take out extension tripod, launch each pin pipe 1.Put extension tripod well according to photographing request, when needs are regulated angle of shooting, height, pin button 5, by guide pillar 15 arming pin in the spacing hole of rotary spanner 3 is ejected, rotate counterclockwise rotary spanner, rotary spanner is in releasing orientation.The elastic force effect of locking spring 8 flicks locking block, and the pin pipe does not stress, and active connection drives pipe 18 free shrink.
After determining the collapsing length of pipe, clockwise rotate rotary spanner,, promote rotary spanner by the interaction of the ramp blocks on the rotary spanner bottom surface with the screw inclined plane of rotation gear piece.Locking screw 11 fixedly is connected as a single entity with rotary spanner, along with the lifting of rotary spanner, drives locking nut 10 by locking screw, and locking block is slowly locked the pin pipe.Owing to be to lock by rotating, 9 pairs of locking nuts of screw are spacing, prevent that the locking nut on the locking block 7 from becoming flexible because of rotation.Behind the rotary spanner half-twist, rotary spanner is in locking state, and arming pin inserts in the spacing hole of rotary spanner automatically by the elastic force effect of relief spring 13, starts insurance function automatically, prevents that rotary spanner from unclamping, and causes unexpected generation.
After shooting is finished, in the time of need packing up tripod, pin button, according to above-mentionedly unclamp, the locking state same principle regains each pipe, the locking device of locking tripod, as shown in Figure 4 by drawing button 20 to draw in tripod is folding, the tripod bag or directly take away of packing into.
