DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1

[0029] refer to Figure 1-5As shown, a multifunctional portable news interview work box of the present invention comprises a box body 101, a battery 103, a bottom plate 201 and a support table 202, a lifting device 203 is arranged between the support table 202 and the bottom plate 201, the lifting device 203 comprises a motor 205, a reducer 206, a shell 207 and a rotating block 204, the output end of the motor 205 is connected to the input end of the reducer 206, the output end of the reducer 206 is fixedly connected to the rotating block 204, the outer cylindrical surface of the rotating block 204 is provided with an external thread, the inner cylindrical surface of the shell 207 is provided with an internal thread, the rotating block 204 is connected to the shell 207 by threads, and the outer cylindrical surface of the rotating block 204 is provided with an internal thread. The upper surface of the shell 207 is fixedly connected to the lower surface of the support table 202, and the lower surface of the shell 207 is in contact with the bottom plate 201. The bottom of the motor 205 is fixedly set on the upper surface of the bottom plate 201. The outer cylindrical surface of the shell 207 is provided with a limit device, and the limit device is in contact with both sides of the inner wall of the box body 101. The support table 202 is provided with a camera support table 302, a telescopic rod 401, a guide groove 310, a sliding device 301 and a teleprompter. The upper end of the sliding device 301 is slidably connected to the camera support table 302, and the lower end is in slidable contact with the guide groove 310. The telescopic rod 401 and the teleprompter are both arranged on the upper surface of the support table 202.

[0030] After installation according to the above connection method, when in use, first adjust the height in the vertical direction according to the required height, turn on the switch of the motor 1 205, the motor 1 205 drives the reducer 206, and transmits the power to the rotating block 204. The rotating block 204 and the shell 207 are connected by threads. The rotating block 204, the motor 1 205 and the reducer 206 are fixed on the bottom plate 201 as a whole. The shell 207 is not restricted in the vertical direction, so as the threads are engaged, the rotating block 204 rotates continuously, and then the shell 207 moves up and down in the vertical direction to achieve the lifting function, and the limit devices are set on both sides of the shell 207 to prevent the shell 207 from rotating circumferentially with the rotating block 204 and losing the lifting function. On the other hand, the camera support platform 302 set on the support table 202 should also be adjusted according to the actual situation. The camera support platform 302 can move freely and adjust the angle by relying on the sliding device 301 in the guide groove 310, and the camera support platform 302 can be rotated to assist in adjusting the angle. The whole set of equipment integrates all the equipment needed for news interviews, solving the problem of the diversity of interviewees' equipment due to the suddenness and timeliness of news interviews, and has the advantages of being portable and able to be operated independently.

[0031] In the above device, a support frame is also provided between the support table 202 and the base plate 201, and the support frame includes a support rod 102, one end of the support rod 102 is rotatably connected to the support table 202 through a hinge, and the other end is rotatably connected to the base plate 201 through a rotating pin. The provision of the support frame can better enhance the overall supporting strength.

[0032] Example 2

[0033] refer to Figure 3 and Figure 5 As shown, on the basis of embodiment one, the sliding device 301 includes a motor 2 305, a positioning block 303, a shell tube 311 and a pull pin 306, the bottom surface of the cylindrical end of the pull pin 306 is fixedly connected to one end of the positioning block 303, the output end of the motor 2 305 is fixedly connected to the lower surface of the camera support platform 302, the camera support platform 302 is in contact and sliding connection with the upper surface of the shell tube 311, a return spring 307 is provided between one end of the positioning block 303 connected to the pull pin 306 and the inner cylindrical surface of the shell tube 311, and the other end is provided with a smooth curved surface, the motor 2 305 and the motor 1 205 are both connected to the battery 103, a plurality of limit grooves 309 are provided on the inner surface of the guide groove 310, and the positioning block 303 is in contact with the limit grooves 309.

[0034] When the camera support platform 302 needs to be rotated, the switch of motor 2 305 is turned on to rotate the camera support platform 302 without manual operation. When the sliding device 301 slides to a certain position, it needs to be positioned to prevent sliding. Hold the pull pin 306 and pull the pull pin outward to retract the positioning block 303 into the shell tube 311. Then, when it reaches the specified position, release the pull pin 306. Under the action of the reset spring 307, the positioning block 303 will pop out and be inserted into the corresponding limit groove 309. One edge of the head end of the positioning block 303 is made into a smooth curved surface, which is conducive to better insertion of the positioning block 303 into the limit groove 309.

[0035] In addition, a motor fixing plate 304 is provided at the bottom of the second motor 305 , and the second motor 305 is fixedly connected to the motor fixing plate 304 . The motor fixing plate 304 is fixed in the shell 311 to prevent the second motor 305 from falling off.

[0036] In the above device, a rolling bearing 308 is provided at one end of the shell 311 away from the camera support platform 302, and the outer surface of the rolling bearing 308 contacts the inner surface of the guide groove 310. The use of the rolling bearing can make the sliding device 301 slide better in the guide groove 310.
