Description

Technical Field

[0001] The utility model relates to the technical field of letter clocks, and particularly relates to a master-slave clock control device. Background Art

[0002] The master clock is a clock mechanism with high precision and can send out time signals to control slave clocks. The slave clock is a clock mechanism controlled by the master clock to reproduce the time of the master clock and keep the running time consistent with the master clock. The master clock can not only receive GPS satellite time signals. When the GPS signal is lost or there are large errors, the system can automatically judge and switch to the time of the Beidou satellite navigation and positioning system with independent intellectual property rights in China. For example, departments such as telecommunications, electric power, and the military have widely used this system.

[0003] However, the signal is weak in some places now. When the master clock is installed underground or in a place with weak signals, during the process of connecting the master clock antenna to Beidou satellite or GPS, it is necessary to continuously adjust the position of the master clock. By constantly changing the position of the master clock, to better connect the satellite signal, so as to prevent signal loss during the process of antenna connecting to the signal, resulting in the problem of master clock calibration failure. To solve this technical problem, the utility model proposes a master-slave clock control device. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a master-slave clock control device, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A master-slave clock control device includes a device body. A motor is installed inside the device body. The output end of the motor is connected to a turntable. A positioning block is connected to the upper surface of the turntable. A positioning rod is connected inside the positioning block. An antenna is installed on the outer surface of the positioning rod. An adjusting card is slidably connected to the outer surface of the turntable. An electric push rod is arranged inside the device body. The output end of the electric push rod is connected to a cross plate.

[0007] Preferably, a chute is opened inside the adjusting card. A ball is installed on the inner side wall of the chute. An installation plate is rotatably connected to the outer surface of the ball. A limiting block is connected to the upper surface of the installation plate. The outer surface of the limiting block is slidably connected to the outer surface of the antenna.

[0008] Preferably, a cover is slidably connected inside the device body. A push block is connected to the upper surface of the cover. The outer surface of the push block is slidably connected to the inside of the device body.

[0009] Preferably, a sensor is installed on the upper surface of the device body. The outer surface of the turntable is rotatably connected to the inside of the device body.

[0010] Preferably, the outer surface of the positioning block is slidably connected to the outer surface of the antenna, and the outer surface of the adjusting card contacts the inside of the device body.

[0011] Preferably, the outer surface of the cross plate is slidably connected to the inside of the device body, and the outer surface of the cross plate is connected to the outer surface of the adjusting card.

[0012] Preferably, the bottom surface of the mounting plate is slidably connected to the upper surface of the adjusting card, and the bottom surface of the limiting block is slidably connected to the upper surface of the adjusting card.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] In the present utility model, through the cooperation between components such as the turntable and the adjusting card, first, the turntable can rotate. By rotating the turntable, the antenna is driven to rotate. By rotating the antenna, the signal reception range is increased. The adjusting card can move up and down. When the adjusting card moves, the antenna is driven to move, so as to adjust the angle between the antenna and the device body, enabling the antenna to point in different directions. Subsequently, by rotating the turntable, the position of the antenna is changed, thereby increasing the reception range of the antenna, making it easier for the device to find a position with stronger signals, so as to better connect to satellite signals in areas with poor signals and prevent signal loss during the connection of the antenna, which is very convenient, and solves the problem of easy signal loss and failure of master clock calibration.

[0015] In the present utility model, through the cooperation between components such as the ball and the limiting block, when the turntable drives the antenna to rotate, the antenna will push the limiting block to rotate. By rotating the limiting block, the mounting plate is driven to move. The movement of the mounting plate will drive the ball to rotate. By rotating the ball, the mounting plate is driven to move, so as to reduce the friction force received when the mounting plate moves, preventing the antenna from being worn due to friction when rotating, thus making the service life of the antenna longer, which is very useful.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a control device for a master-slave clock includes a device body 1. A motor 2 is installed inside the device body 1. The output end of the motor 2 is connected to a turntable 3. The device body 1 fixes the position of the motor 2 to prevent the motor 2 from rotating selflessly when starting. The motor 2 fixes the position of the turntable 3 and drives the turntable 3 to rotate by starting the motor 2. The motor 2 only rotates one circle when starting and will reverse after rotating one circle forward.

[0024] The upper surface of the turntable 3 is connected to a positioning block 4. The inside of the positioning block 4 is connected to a positioning rod 5. The turntable 3 fixes the position of the positioning block 4 and drives the positioning block 4 to move when the turntable 3 rotates. The positioning block 4 fixes the position of the positioning rod 5 and drives the positioning rod 5 to rotate when the positioning block 4 rotates.

[0025] An antenna 6 is installed on the outer surface of the positioning rod 5. An adjusting card 7 is slidably connected to the outer surface of the turntable 3. The antenna 6 can rotate around the positioning rod 5 as an axis. The inside of the positioning rod 5 is hollow. The wire inside the antenna 6 can be introduced into the positioning rod 5, then into the turntable 3, and then from the turntable 3 into the device body 1. The turntable 3 limits the position of the adjusting card 7, enabling the installer to know the specific position where the adjusting card 7 can be installed, thus facilitating the installation of the adjusting card 7.

[0026] An electric push rod 8 is arranged inside the device body 1. The output end of the electric push rod 8 is connected to a horizontal plate 9. The device body 1 limits the position of the electric push rod 8 to prevent the electric push rod 8 from moving easily. The electric push rod 8 fixes the position of the horizontal plate 9 and drives the horizontal plate 9 to move when the electric push rod 8 starts. The horizontal plate 9 drives the adjusting card 7 to move, and the adjusting card 7 moves to push the antenna 6, causing the antenna 6 to rotate around the positioning rod 5. When the electric push rod 8 starts, the motor 2 also starts, and the motor 2 starts to rotate the antenna 6, thereby changing the orientation of the antenna 6, enabling the antenna 6 to rotate while moving upward.

[0027] The inside of the adjustment card 7 is provided with a sliding groove 10. The inner side wall of the sliding groove 10 is provided with a ball 11. The inner side wall of the sliding groove 10 is relatively smooth. When the ball 11 moves on the inner side wall of the sliding groove 10, the frictional force it receives is small. The sliding groove 10 will hold the ball 11 in place, preventing the ball 11 from coming out of the sliding groove 10. By the rolling of the ball 11, the frictional force is further reduced.

[0028] The outer surface of the ball 11 is rotatably connected to a mounting plate 12. The upper surface of the mounting plate 12 is connected with a limiting block 13. The outer surface of the limiting block 13 is slidably connected to the outer surface of the antenna 6. When the mounting plate 12 moves, it will drive the ball 11 to rotate. The ball 11 cannot be taken out of the mounting plate 12. By the rotation of the ball 11, the frictional force when the mounting plate 12 moves is reduced. The mounting plate 12 will fix the position of the limiting block 13. When the limiting block 13 moves, it will drive the mounting plate 12 to move. The antenna 6 will be stuck into the limiting block 13. When the motor 2 rotates the antenna 6, the antenna 6 will drive the limiting block 13.

[0029] A cover 14 is slidably connected to the inside of the device body 1. The upper surface of the cover 14 is connected with a push block 15. The outer surface of the push block 15 is slidably connected to the inside of the device body 1. The device body 1 will limit the position of the cover 14. The frictional force between the device body 1 and the cover 14 is relatively large, and the cover 14 cannot easily slide inside the device body 1. The antenna 6 is hidden by the cover 14, thereby increasing the aesthetic degree of the device. The cover 14 will fix the position of the push block 15. The user can move the push block 15 to change the position of the cover 14.

[0030] An inductor 16 is installed on the upper surface of the device body 1. The outer surface of the turntable 3 is rotatably connected to the inside of the device body 1. The device body 1 will fix the position of the inductor 16. After the device is started, when the antenna 6 moves to a position with better signal, the inductor 16 will stop the motor 2 and the electric push rod 8. The device body 1 will provide support for the turntable 3, so that the pressure on the turntable 3 will not all act on the motor 2.

[0031] The outer surface of the positioning block 4 is slidably connected to the outer surface of the antenna 6. The outer surface of the adjustment card 7 contacts the inside of the device body 1. When the positioning block 4 moves, it will push the antenna 6 to move. The device body 1 will limit the position where the adjustment card 7 can move, preventing the adjustment card 7 from moving downward continuously.

[0032] The outer surface of the cross plate 9 is slidably connected to the inside of the device body 1. The outer surface of the cross plate 9 is connected to the outer surface of the adjustment card 7. The device body 1 will limit the direction in which the cross plate 9 can move, so as to avoid deviation in the position where the cross plate 9 moves. When the cross plate 9 moves, it will drive the adjustment card 7 to move.

[0033] The bottom surface of the mounting plate 12 is slidably connected to the upper surface of the adjustment card 7, and the bottom surface of the limit block 13 is slidably connected to the upper surface of the adjustment card 7. The adjustment card 7 can provide support for the mounting plate 12 and the limit block 13.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
