Description

Small electric lifter

The utility model relates to a kind of small-sized electric The Cloud Terrace that is used for camera or vidicon camera, is particularly suitable for on-the-spot the use.

At present, be applicable to that the electric platform kind of camera or camera chain is less, the small-sized electric The Cloud Terrace is more rare.The existing ubiquitous matter of utmost importance of electric platform is feed cable or camera cable routing problem.What used power supply was commonly used is strong Ac, because the clockwise and anticlockwise of strong AC motor commutation running needs to use relay or contactor, so run into tedious contact arcing problem through regular meeting in using, deals with pretty troublesome; The cabling of vidicon camera and The Cloud Terrace normally appoints camera cable to drag externally, and this very easily causes cable to bend repeatedly because of the horizontal hunting of The Cloud Terrace, thereby causes disconnection fault.Next is that existing The Cloud Terrace pitching movement angle is little, generally mostly is+45 ° to-45 °, and on-the-spot the use then requires range of pitch motion greatly, in addition, development along with the technology in modern age, the volume of vidicon camera is more and more more little, and the small-sized electric The Cloud Terrace is provided, and has become current urgency problem to be solved.

The purpose of this utility model provides a kind of small-sized electric The Cloud Terrace, its compact structure, and volume is little, and is in light weight, adopts the low voltage DC motor drive transmission device, makes vidicon camera and The Cloud Terrace realize that cabling is integrated, effectively overcome the deficiency of known technology.

The purpose of this utility model is achieved in that this device comprises upper body and the lower body that fits together, its driving mechanism that is assembled in respectively in upper body and the lower body all adopts low voltage DC motor to drive, lower body hollow output shaft and upper body are fixed together, the upper body is equipped with the inside that is connected with camera cable and walks line socket, the inner lead of lower body hollow output shaft is passed in this socket utilization, be connected with the external socket that is contained in lower body, realize inner cabling.

Because the utility model adopts the low voltage DC motor driving mechanism, so the relay or the contactor that needn't adopt existing AC motor to use, switch or transistor commutating circuit by external control apparatus, can realize the forward and backward commutation running of this machine, effectively avoid contact arcing problem, bring great convenience to being attached thereto the control system that connects.Be fixed in because of the upper body on the hollow output shaft of lower body, the inner lead that the lower body hollow output shaft is passed in the socket utilization of upper body and lower body is connected, realize that vidicon camera and The Cloud Terrace cabling are integrated, camera cable no longer drags outside machine, has avoided swing because of The Cloud Terrace to cause and has bent the disconnection fault that causes repeatedly.The reasonable Arrangement of driving mechanism has been dwindled The Cloud Terrace boundary dimension significantly, makes its volume little, is specially adapted to on-the-spot the use.Therefore, this device has not only been simplified its control system, and obviously improves the reliability and the using effect of system.

Below in conjunction with accompanying drawing the utility model is further described.
