Description

Technical Field

[0001] The utility model relates to the technical field of video signal input structures, and particularly relates to a video signal input structure. Background Art

[0002] A video signal input structure refers to the process in which an external video recorder or camera records the monitored area and then inputs it to a monitor.

[0003] For example, a video signal output device and a video signal input device with the authorization announcement number of "CN1179564C" perform scrambling and descrambling to shift the signal lines in each cycle, and each cycle is equivalent to a horizontal scanning time interval or n times of a horizontal scanning time interval. The timing shift of each signal line is during the horizontal blanking period of the analog component video signal. When the result of the mutual communication between the output device and the input device is to establish authorization, both the scrambling and descrambling modes are determined according to the information obtained from each other during the mutual communication. However, in the use of the video signal input structure, it needs to be connected with wires, and in order to save space, the video signal input structures are overlapped and placed. The wires connected to the top video signal input structure will bend downward and press the wires connected to the lower video signal input structure, which will increase the load on the wire connection of the lower video signal input structure, easily damage the connection of the video signal input structure, and shorten the service life of the video signal input structure. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the connection of the video signal input structure is damaged and the service life of the video signal input structure is shortened, and a video signal input structure is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a video signal input structure, including a video signal transmitter and a vertical plate. The left and right sides of the back of the video signal transmitter are respectively fixedly connected to the inner side of the vertical plate. Four corners of the top of the video signal transmitter are respectively connected with a control structure. The lower parts of the left and right sides of the front of the video signal transmitter are respectively fixedly connected with straight plates. The outer walls of the straight plates are connected with a control structure. The top of the control structure is connected with a handle. A plurality of round holes are processed on the top of the straight plate.

[0007] Preferably, the support structure includes a sleeve plate and a first screw. The inner wall of the sleeve plate is inserted into the outer wall of the straight plate. The top of the sleeve plate is threadedly connected to the outer wall of the first screw. A bracket is fixedly connected to the front of the inner side of the sleeve plate.

[0008] Preferably, the bottom of the outer wall of the first screw is inserted into the round hole at the top of the straight plate.

[0009] Preferably, the top of the first screw rod is fixedly connected to the bottom of the grip.

[0010] Preferably, the control structure includes a vertical cylinder and a second screw rod. The bottoms of multiple vertical cylinders are respectively fixedly connected to the four corners of the top of the video signal transmitter. The inner wall of the vertical cylinder is threadedly connected to the bottom of the outer wall of the second screw rod, and the top of the second screw rod is fixedly connected to a top plate.

[0011] Preferably, round openings are respectively processed on the upper and lower sides of the front surface of the vertical plate.

[0012] A video signal input structure proposed by the present utility model has the beneficial effect that: through the upward rotation of the first screw rod in the support structure by means of the sleeve plate, the bottom of the outer wall of the first screw rod is disengaged from the round opening inserted into the top of the straight plate, and then the sleeve plate moves forward on the outer wall of the straight plate. The moving sleeve plate drives the bracket to move forward. At this time, the bending position of the wire above the bracket changes, causing the bending positions of the wires inserted into the vertically overlapping video signal transmitters to be misaligned. Subsequently, the grip drives the first screw rod to rotate downward, so that the bottom of the outer wall of the first screw rod is inserted into the corresponding round opening at the top of the straight plate, avoiding damage to the connection part of the video signal input structure and ensuring the service life.

[0018] The present utility model will be further described below with reference to the drawings:

[0019] Embodiment 1:

[0020] Please refer to Figures 1-4: In this embodiment, a video signal input structure includes a video signal transmitter 1 and a vertical plate 6. The left and right sides of the video signal transmitter 1 are respectively fixedly connected to the inner sides of the vertical plate 6. How to operate and use the video signal transmitter 1 is already prior art and will not be elaborated in detail. The model is selected according to the usage requirements. Four corners of the top of the video signal transmitter 1 are respectively connected with a control structure 3. The lower parts of the left and right sides of the front of the video signal transmitter 1 are respectively fixedly connected with straight plates 4. The outer walls of the straight plates 4 are connected with a control structure 3. The top of the control structure 3 is connected with a grip 5. Multiple round holes are processed on the top of the straight plate 4.

[0021] The support structure 2 includes a sleeve plate 201 and a first screw 202. The inner wall of the sleeve plate 201 is inserted into the outer wall of the straight plate 4. The top of the sleeve plate 201 is threadedly connected to the outer wall of the first screw 202. The first screw 202 rotates up and down through the top of the sleeve plate 201 under force. A support 203 is fixedly connected to the front of the inner side of the sleeve plate 201. The front of the support 203 is an arc slope, which can support the wire. The bottom of the outer wall of the first screw 202 is inserted into the round hole at the top of the straight plate 4. The top of the first screw 202 is fixedly connected to the bottom of the grip 5. The grip 5 facilitates driving the first screw 202 to rotate.

[0022] By rotating the first screw 202 upward through the sleeve plate 201 in the support structure 2, the bottom of the outer wall of the first screw 202 is disengaged from the round hole inserted into the top of the straight plate 4. Then the sleeve plate 201 moves forward on the outer wall of the straight plate 4. The moving sleeve plate 201 drives the support 203 to move forward. At this time, the bending position of the wire above the support 203 will be changed, so that the bending positions of the wires inserted into the overlapping video signal transmitters 1 up and down are misaligned. Subsequently, the grip 5 drives the first screw 202 to rotate downward, so that the bottom of the outer wall of the first screw 202 is inserted into the corresponding round hole at the top of the straight plate 4, avoiding damage to the connection part of the video signal input structure and ensuring the service life.

[0023] The control structure 3 includes a vertical cylinder 301 and a second screw 302. The bottoms of multiple vertical cylinders 301 are respectively fixedly connected to the four corners of the top of the video signal transmitter 1. The inner wall of the vertical cylinder 301 is threadedly connected to the bottom of the outer wall of the second screw 302. The second screw 302 rotates up and down through the inner wall of the vertical cylinder 301 under force. The top of the second screw 302 is fixedly connected to a top plate 303. Round holes are respectively processed on the upper and lower sides of the front of the vertical plate 6.

[0024] Working principle:

[0025] Installation of the video signal input structure:

[0026] Fit the vertical plate 6 to the connecting frame, then pass a bolt through the vertical plate 6 and the connecting frame and fix them by threading. Then insert the wire into the front interface of the video signal transmitter 1. At this time, the wire will rest on the bracket 203. Then, according to the bending situation of the wires connected to other video signal transmitters 1, rotate the grip 5 upwards with the first screw 202 through the sleeve plate 201, so that the bottom of the outer wall of the first screw 202 disengages from the circular opening inserted into the top of the straight plate 4. Then the sleeve plate 201 moves forward on the outer wall of the straight plate 4, and the moving sleeve plate 201 drives the bracket 203 to move forward. At this time, the bending position of the wire above the bracket 203 will change, causing the bending positions of the wires inserted into the overlapping video signal transmitters 1 to be misaligned. Subsequently, rotate the grip 5 downwards with the first screw 202, so that the bottom of the outer wall of the first screw 202 is inserted into the corresponding circular opening at the top of the straight plate 4. The other end of the wire connected to the video signal transmitter 1 is connected to the video display device, and the video signal transmitter 1 sends the signal to the video display device through the wire.

[0027] Placement and support of the video signal input structure:

[0028] Thread the bottom of the outer wall of the second screw 302 with the inner wall of the vertical cylinder 301 to complete the fixation of the top plate 303. Then fit the second video signal transmitter 1 to the top of the top plate 303, so that there is a gap when the video signal transmitters 1 overlap, ensuring the normal heat dissipation of the video signal transmitters 1.

[0029] Embodiment 2:

[0030] Please refer to Figures 1-4 : In this embodiment, a video signal input structure further includes fin plates 7, and the outer walls of a plurality of fin plates 7 are fixedly connected to the top of the video signal transmitter 1.

[0031] Working principle:

[0032] During the use of the video signal transmitter 1, internal components will generate heat. The fin plates 7, due to their copper material, can conduct the heat inside the video signal transmitter 1 to complete heat dissipation.
