DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution: a screw jack with an intelligent control system, including a housing 1, a lifting control mechanism 2 is arranged on the surface of the housing 1, a packaging mechanism 3 is arranged on one side of the surface of the housing 1, and a mounting plate 4 is connected to one side of the surface of the housing 1;

[0020] The lifting control mechanism 2 includes a trapezoidal screw rod 201, a turbine 202, a magnetic grating ruler 203, a control motor 204, a connecting disk 205, a worm 206 and a magnet 207. The trapezoidal screw rod 201 is connected through the surface of the housing 1, the turbine 202 is embedded in the housing 1, the magnetic grating ruler 203 is embedded on one side of the surface of the housing 1, the control motor 204 is installed on one side of the surface of the housing 1, one end of the trapezoidal screw rod 201 is connected to the connecting disk 205, one end of the control motor 204 is connected to the worm 206, and a magnet 207 is embedded on one side of the surface of the connecting disk 205. When in use, first electrically connect a computer or a mobile phone to the magnetic head in the magnetic grating ruler 203, and set the initial distance between the magnetic grating ruler 203 and the magnet 207. Then set the moving distance of the trapezoidal screw rod 201 on the mobile phone or the computer. Then the magnetic grating ruler 203 controls the start of the control motor 204. At this time, the control motor 204 drives the worm 206 to rotate. Subsequently, the worm 206 drives the turbine 202 to rotate. Then the turbine 202 drives the trapezoidal screw rod 201 to move horizontally. At the same time, the trapezoidal screw rod 201 drives the connecting disk 205 to move. And the magnetic grating ruler 203 on one side of the connecting disk 205 continuously moves away from the magnet 207. At this time, the magnetic grating ruler 203 calculates and measures the moving distance of the trapezoidal screw rod 201 according to the initial distance from the magnet 207. When the set distance is reached, the magnetic grating ruler 203 controls it to stop through the control system of the control motor 204. At this time, the precise distance of the intelligent control of the movement of the trapezoidal screw rod 201 is completed.

[0021] Furthermore, the magnetic grating ruler 203 and the magnet 207 are horizontally aligned, and the worm 206 and the turbine 202 are meshed and connected. Through the settings of the magnetic grating ruler 203 and the magnet 207, when in use, the magnetic grating ruler 203 cooperates with the magnet 207 to accurately measure the moving distance of the trapezoidal screw rod 201. According to the set initial distance and the detected change in the distance from the magnet 207 in real time, the actual displacement of the trapezoidal screw rod 201 is calculated, and the control motor 204 is stopped when the set distance is reached, realizing precise control. The magnet 207 cooperates with the magnetic grating ruler 203 to provide a magnetic field source for the magnetic grating ruler 203, enabling the magnetic grating ruler 203 to detect the distance change, thereby realizing the measurement of the moving distance of the trapezoidal screw rod 201.

[0022] Furthermore, one end of the trapezoidal screw rod 201 is connected through the turbine 202, and the trapezoidal screw rod 201 and the turbine 202 form a moving relationship. Through the setting of the turbine 202, when in use, the turbine 202 can convert the rotational motion into a linear motion to realize the horizontal movement of the trapezoidal screw rod 201.

[0023] Furthermore, the encapsulation mechanism 3 includes an internal thread 301, a thread groove 302, a sealing plate 303, an external thread 304, a bolt 305, and a connection hole 306. An internal thread 301 is provided on the inner side of the housing 1, a thread groove 302 is provided on one side of the surface of the housing 1, a sealing plate 303 is connected to one side of the surface of the housing 1, an external thread 304 is connected to one side of the surface of the mounting plate 4, the thread groove 302 is threadedly connected to a bolt 305, and a connection hole 306 is provided on the surface of the sealing plate 303. Through the settings of the internal thread 301, the thread groove 302, the sealing plate 303, the external thread 304, the bolt 305, and the connection hole 306, during use, after installing the parts of the screw jack into the interior of the housing 1, first rotate the mounting plate 4 around one end of the trapezoidal lead screw 201 until the external thread 304 on the surface of the mounting plate 4 is threadedly connected to the internal thread 301 on the inner side of the housing 1. At this time, the mounting plate 4 is successfully installed on the surface of the housing 1. Subsequently, pass the sealing plate 303 through one end of the worm 206 so that the connection hole 306 on its surface is horizontally aligned with the thread groove 302. Then, use the bolt 305 to pass through the connection hole 306 and be threadedly connected to the thread groove 302, thereby installing the sealing plate 303 on one side of the housing 1. At this time, the encapsulation of the screw jack is completed.

[0024] Furthermore, the connection hole 306 is horizontally aligned with the thread groove 302, and the external thread 304 and the internal thread 301 are of matching dimensions. Through the setting of the connection hole 306, during use, the connection hole 306 can provide a passage for the bolt 305 to pass through, enabling the bolt 305 to smoothly connect the sealing plate 303 and the housing 1. The position and dimensions of the connection hole 306 need to match the thread groove 302 and the bolt 305.

[0025] Working principle: First, after installing the parts of the screw jack into the interior of the housing 1, rotate the mounting plate 4 around one end of the trapezoidal lead screw 201 until the external thread 304 on the surface of the mounting plate 4 is threadedly connected to the internal thread 301 on the inner side of the housing 1. At this time, the mounting plate 4 is successfully installed on the surface of the housing 1. Subsequently, pass the sealing plate 303 through one end of the worm 206 so that the connection hole 306 on its surface is horizontally aligned with the thread groove 302. Then, use the bolt 305 to pass through the connection hole 306 and threadedly connect it to the thread groove 302, thereby installing the sealing plate 303 on one side of the housing 1. At this time, the encapsulation of the screw jack is completed. After that, when in use, first electrically connect a computer or a mobile phone to the magnetic head in the magnetic scale 203 and set the initial distance between the magnetic scale 203 and the magnet 207. Then, set the moving distance of the trapezoidal lead screw 201 on the mobile phone or computer. Then, the magnetic scale 203 controls the start of the control motor 204. At this time, the control motor 204 drives the worm 206 to rotate. Subsequently, the worm 206 drives the turbine 202 to rotate. Then, the turbine 202 drives the trapezoidal lead screw 201 to move horizontally. At the same time, the trapezoidal lead screw 201 drives the connection disk 205 to move. And the magnetic scale 203 on one side of the connection disk 205 continuously moves away from the magnet 207. At this time, the magnetic scale 203 calculates and measures the moving distance of the trapezoidal lead screw 201 according to the initial distance from the magnet 207. After reaching the set distance, the magnetic scale 203 controls it to stop through the control system of the control motor 204. At this time, the precise distance of the intelligent control of the movement of the trapezoidal lead screw 201 is completed.
