Description

Technical Field

[0001] The utility model relates to the field of radio and television, and particularly relates to an indoor electric control slide rail which is convenient for concealed installation. Background Art

[0002] Broadcast-level remotely controlled cameras are widely used in studios, courtrooms, conference venues (including video conferences), sports events, large-scale cultural and entertainment activities, and telemedicine and other fields. Such cameras use an intelligent remote control pan-tilt head - equivalent to a professional manipulator - to replace the cameraman's on-site operation, enabling remote control. Currently, remotely controlled cameras in practical applications basically use fixed brackets for support and installation, such as ceiling suspension, wall mounting, or tripod support installation, etc. However, these fixed support remote shooting positions only solve the problem of not disturbing the conference site. For occasions where the shooting angle needs to be adjusted appropriately, even if you want to move the camera (translate or lift) a distance of 1 meter, you have to add 1 more shooting position. Thus, camera moving support devices with "lifting" or "translation" functions have begun to be widely used in the market. However, except for expensive imported professional equipment (starting at about 200,000 yuan), there are only products for translating light cameras over short distances, and none of them can truly solve the problems of jitter and swing during operation, small stroke, large noise, complex structure, inability to be concealed and fixed, and especially the problem of "power failure and falling" often occurs after the load is vertically lifted. Content of the Utility Model

[0003] The purpose of the utility model is to provide an indoor electric control slide rail which is convenient for concealed installation to solve the problems existing in the above-mentioned prior art.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] An indoor electric control slide rail convenient for concealed installation includes a vertically arranged guide rail. Limit blocks are provided at both the bottom end and the top end of the guide rail. A slider is slidably installed on the guide rail. A driving device is installed at the top end of the slider. The driving device includes a driving motor, a speed reducer, a noise reduction housing, a worm, a turbine, a driving wheel, a driven wheel, and a transmission belt. The driving motor is fixedly installed inside the noise reduction housing. The worm is rotatably installed at the inner bottom end of the noise reduction housing. The turbine is rotatably installed inside the noise reduction housing at the bottom end. The turbine is in transmission engagement with the worm. One end of the worm passes through the noise reduction housing and extends to the outside of the noise reduction housing. The driven wheel is sleeved on the end of the worm located outside the noise reduction housing. The output shaft of the driving motor passes through and extends to the outside of the noise reduction housing. The driving wheel is sleeved on the output shaft of the driving motor located outside the noise reduction housing. The driving wheel and the driven wheel are in transmission connection through the transmission belt. Anti-slip patterns are provided on the surface of the guide rail. The surface of the turbine is in contact with the surface of the guide rail. The driving motor is used to drive the turbine to roll on the surface of the guide rail through the driving wheel, the transmission belt, the driven wheel, and the worm.

[0006] By adopting the above technical solution, the transmission cooperation between the turbine and the worm can only achieve one-way transmission. Therefore, after power failure, the turbine cannot transmit power back to the worm in the reverse direction, so the turbine will not rotate, thus avoiding the problem of falling down after power failure.

[0007] In a further embodiment, the limiters are both bolted and fixed to the guide rail.

[0008] In a further embodiment, the diameter of the driving wheel is smaller than that of the driven wheel.

[0009] In a further embodiment, grid patterns are provided on the surface of the transmission belt.

[0010] In a further embodiment, a wear-resistant coating is provided on the surface of the guide rail.

[0011] In a further embodiment, a traveling cable chain is provided on one side of the slider.

[0012] In summary, the present utility model has the following beneficial effects:

[0013] 1. By adopting the above technical solution, the transmission cooperation between the turbine and the worm can only achieve one-way transmission. Therefore, after power failure, the turbine cannot transmit power back to the worm in the reverse direction, so the turbine will not rotate, thus avoiding the problem of falling down after power failure.
