Specific embodiment
Purpose, technical scheme and advantage to make the utility model embodiment are clearer, new below in conjunction with this practicality
Attached drawing in type embodiment, is explicitly described the technical scheme in the embodiment of the utility model, it is clear that described reality
It is the utility model part of the embodiment to apply example, instead of all the embodiments.Based on the embodiment in the utility model, ability
It is new to belong to this practicality for domain those of ordinary skill all other embodiments obtained without making creative work
The range of type protection.
Fig. 1 is the schematic diagram that the liftable photographic device that the utility model embodiment provides is in increasing state, such as Fig. 1 institutes
Show, which includes：First segment pillar 1 and the second section pillar 11 being arranged in the first segment pillar 1；Institute
The outer wall for stating the second section pillar 11 is equipped with the multiple first pulleys 231 being circular layout, and is set on the inner wall of the first segment pillar 1
There is the first slideway coordinated with the first pulley 231；The inner wall of the first segment pillar 1 is equipped with electromagnet 4, the electromagnet
4 connect with the variable resistance being arranged on the first segment pillar 1；The second section pillar 11 is equipped with permanent magnet 24；It is described
The outer wall of second section pillar 11 is equipped with video camera 19.
Wherein, electromagnet is switched on generating a kind of device of electromagnetism.It is externally wrapped with what is matched with its power in iron core
Conductive winding, this coil to alive have magnetism as magnet, it is also referred to as electromagnet (electromagnet).
Usually bar shaped or ungulate shape is made in it by we, so that iron core is more prone to magnetize.In addition, in order to which electromagnet power-off is made to disappear immediately
Magnetic, we are often made of the faster soft iron of demagnetization or silicon steel material.Such electromagnet is magnetic when being powered, and powers off
Magnetic just disappears therewith afterwards.
Wherein, permanent magnet (permanent magnet), i.e. alnico magnets can be natural products, also known as natural magnetic
Stone, can also be by manually manufacturing (most strong magnet is ndfeb magnet).It has wide hysteresis loop, high-coercive force, high remanent magnetism,
Magnetic material can be kept constant once magnetization.Also known as permanent-magnet material, hard magnetic material.In, permanent magnet works in depth
Magnetic saturation and after magnetizing the auspicious loop line of magnetic the second quadrant demagnetization part.Permanent magnet should have coercivity H as high as possible, remanent magnetism
Br and maximum magnetic energy product (BH) m, to ensure the magnetism of the maximum magnetic energy of storage and stabilization.
Specifically, with reference to Fig. 2 a-2c, Fig. 3 a-3c, Fig. 5 a and Fig. 5 c, first is set to slide on the inner wall of first segment pillar 1
The multiple first pulleys 231 being circular layout, and first slideway and first are set on road and the outer wall for saving pillar 11 second
Pulley 231 matches, that is, the first slideway and the model of first pulley 231 match, and the first slideway and first pulley 231
Quantity is identical.Slip that then can be by first pulley 231 in the first slideway drives the lifting of the second section pillar 11；It is and sliding
The mode being combined with slideway is taken turns, the second section pillar 11 can also be avoided to rotate in first segment pillar 1, ensure that can rise
The stability of photographic device drops.
And first segment pillar 1 inner wall set electromagnet 4, and the electromagnet 4 with it is variable on first segment pillar 1
Resistance is connected, for example, variable resistance is arranged on the outer wall of first segment pillar 1；It then can be by adjusting the electricity of the variable resistance
Resistance value changes the magnetic force size of electromagnet 4.Then, the electromagnet 4 and 24 same sex phase of permanent magnet on the second section pillar 11 are utilized
The principle of reprimand, by changing the magnetic force size of electromagnet, to push the first pulley 231 on the second section pillar 11 in first segment branch

Slideway；The outer wall of the second section pillar 11 is equipped with gear 12, is embedded with and the tooth on the outer wall of the third section pillar 20
The rack 18 of 12 cooperation of wheel, and the insert depth of the rack 18 is high consistent with the tooth of the rack 18；The video camera 19 is pacified
On the outer wall of the third section pillar 20.
Specifically, rotate gear 12, for example, by the way that crank 13 is nested in gear 12, then shake manually crank 13 with
Rotate gear 12.Then, it by gear 12 and the interlocking of rack 18, is moved up and down with band carry-over bar 18 so that third
Section pillar 20 moves up and down in the second section pillar 11, so as to achieve the purpose that adjust 19 height of video camera.For example, pass through shake
Crank 13 makes gear 12 be moved up with carry-over bar 18, then third section pillar 20 rises in the second section pillar 11.It is taken the photograph when reaching
After the desired height of camera 19,143 and the 4th location hole 144 of third location hole is passed through with the second positioning element 102, by third section
Pillar 20 is fixed.When without crank 13, crank 13 can be placed in equipment box 2.
The liftable photographic device that the utility model embodiment provides, can be according to installation using liftable mounting means
Requirement for height implements first and second section combination, and three kinds of schemes of second and third section combination and first, second and third section combination ensure that peace
Maintenance needs are filled, while ensure that the safety of operating personnel.First segment pillar, the second section pillar and third section pillar use aluminium
Alloy makes, and material is relatively light.Third section pillar is realized by gear-driven principle and lifted, using manually by portable
Third section pillar has been shaken and fixed again by crank, and construction is very simple, convenient for promoting.Second and third section pillar is same entirely through magnetic field
Property the principle repelled each other realize lifting, permanent magnet is fixedly mounted under the second section pillar, electricity is fixedly mounted in first segment pillar lower part
Magnet, electromagnet are connected with variable resistance in equipment box, and the resistance value of variable resistance is adjusted come regulating magnet by switching knob
The size of magnetic force, and then second and third section pillar is integrally risen or fallen slowly, it is easy to operate, noiseless, without friction.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
