Description

Technical Field

[0001] The utility model relates to the technical field of signal testing devices, in particular to a reinforcement structure. Background Art

[0002] Television signal refers to the television signal which includes synchronization signal in addition to image signal. The so-called synchronization means that the line and field scanning pace of the camera end (transmitter) must be completely consistent with the scanning pace of the display end (receiver), that is, the same frequency and phase are required to obtain a stable picture. At present, in order to better understand the strength of television signals, most users will use television signal testing equipment to test the current television signals.

[0003] For example, Chinese patent CN207835678U, the utility model provides a television signal test device, which relates to the field of television signal test devices. The television signal test device includes a test box, and a base is fixedly connected to the four corners of the bottom of the test box, and a rotating shaft is rotatably connected to the base, and the surface of the rotating shaft is fixedly connected to the middle of the rotating rod, and the four corners of the bottom of the test box are fixedly connected to an arc plate, an arc groove is provided on the arc plate, a fixed column is fixedly connected to the front surface of one end of the rotating rod, and the fixed column is located inside the arc groove, a strip hole is provided at one end of the rotating rod, and a fixed plate is fixedly connected to the back of the rotating rod and the position corresponding to the strip hole, a first spring is fixedly connected to one side of the fixed plate, and an end of the first spring away from the fixed plate is fixedly connected to the sliding plate, and a clamping rod is fixedly connected to the center of the front surface of the sliding plate. The television signal test device is easy and fast to move, simple to operate, and has strong applicability.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0032] See also Figure 2 In order to stably fix the TV to be tested, the fixing mechanism 1 in this embodiment includes a supporting assembly, an air pump 103, an air pipe 104, a connecting box 105, a connecting pipe 106 and a vacuum suction cup 110.

The connecting pipe 106 is a corrugated hose, so that the connecting pipe 106 can pass through the shielding box 2 to connect with the vacuum suction cup 110 and move with the movement of the vacuum suction cup 110.

[0034] In this embodiment, the support assembly includes a bidirectional screw rod 101, a limit rod 102, a motor 107, a fixed box 108 and a movable seat 109.

[0035] It should be noted that the fixing mechanism 1 adsorbs the TV through the cooperation of the air pump 103, the air pipe 104, the connecting box 105, the connecting pipe 106 and the vacuum suction cup 110, so that the TV cannot move at all, thereby stably fixing the TV, so that the TV will not move during the signal strength test to interfere with the signal, thereby causing deviations in the test results.

The exhaust fan 301 is fixed on the left side of the collection box 303, and the dustproof net 302 is fixed on the left side wall of the inner cavity of the collection box 303. The control method of this application is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and circuit connection in detail.

[0037] In this embodiment, an air outlet for connecting to the exhaust fan 301 is opened on the left side of the collection box 303, and the dustproof net 302 is fixed inside the air outlet, so that dust will not enter the exhaust fan 301 while the exhaust fan 301 absorbs dust. A connecting hole for the collection pipe 304 to pass through is opened on the upper surface of the shielding box 2, and the collection pipe 304 is slidably connected to the inside of the shielding box 2 through the connecting hole, so that the collection pipe 304 can be connected to the collection box 306.

[0039] The working principle of the above embodiment is:

[0040] (1) When it is necessary to test the signal strength of a television, the motor 107 is first started. The motor 107 drives the bidirectional screw 101 to rotate through the output shaft. While the bidirectional screw 101 rotates, it drives the two movable seats 109 to move to the left and right sides respectively, and drives the vacuum suction cup 110 to move together through the movable seat 109. When the distance between the two opposite sides of the two movable seats 109 is slightly equal to the length of the television, the motor 107 is turned off. Then the television is placed on the vacuum suction cup 110 and the dust removal mechanism 3 is started to clean the dust on the shielding box 2 and the television. At the same time, the air pump 103 is started so that the vacuum suction cup 110 absorbs and fixes the television. Then the door of the shielding box 2 is closed and the signal testing device is started to detect the strength of the television signal. The fixing mechanism 1 absorbs the television through the cooperation of the air pump 103, the air pipe 104, the connecting box 105, the connecting pipe 106 and the vacuum suction cup 110, so that the television cannot move at all, thereby stably fixing the television so that the television will not move during the signal strength test to interfere with the signal, thereby causing deviations in the test results.

[0041] (2) When the TV is fixed, start the exhaust fan 301. The air diffuser 305 draws the dust inside the shielding box 2 and the dust on the TV into the collecting box 306. At the same time, the collecting tube 304 draws the dust inside the collecting box 306 and transports it to the collecting box 303, thereby cleaning the dust on the shielding box 2 and the TV. When the door of the shielding box 2 is closed, turn off the exhaust fan 301. The dust removal mechanism 3 cleans the dust on the shielding box 2 and the TV through the cooperation of the exhaust fan 301, the collecting box 303, the collecting tube 304, the air diffuser 305 and the collecting box 306, so as to avoid the dust on the shielding box 2 or the TV causing an increase in the shielding degree, thereby further weakening the TV signal, and causing the test result of the signal testing device to deviate greatly from the expected result.
