DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The utility model provides a technical solution: Figure 1-3 The utility model discloses a PLC remote debugging device, including an antenna 1 for PLC remote debugging networking, the antenna 1 includes a device body 11 and a base 12, a spherical block 2 is rotatably mounted on the top of the base 12, and the top of the spherical block 2 extends outside the base 12 and is fixedly connected to the device body 11, and a positioning mechanism 3 is provided in the base 12.

[0021] In this embodiment, when performing remote debugging of the PLC, the operator first places the base 12 on the desktop, and forms a negative pressure chamber at the bottom of the base 12 through the positioning mechanism 3, and fixes the base 12 on the desktop by absorption, and then connects the connecting wire on the device body 11 to the PLC. Then the operator releases the constraint limit of the spherical block 2 by the positioning mechanism 3, and pushes the device body 11 to adjust the inclination angle of the antenna 1, so that the PLC is stably connected to the Internet of Things. Then the operator re-constrains the spherical block 2 through the positioning mechanism 3, so that the inclination angle of the antenna 1 remains stable. Finally, the external computer is connected to the PLC through the Internet of Things, and the PLC debugging operation is performed remotely.

[0022] In a further preferred embodiment of the present invention, Figure 2 As shown, the positioning mechanism 3 includes a push block 32, a circular groove 31 with a T-shaped cross section is opened at the center position of the bottom side of the base 12, the push block 32 is arranged in the circular groove 31, and the outer peripheral wall of the push block 32 is connected to the inner wall of the circular groove 31, and a spring 33 is arranged on the bottom side of the push block 32, and the two ends of the spring 33 are fixedly connected to the push block 32 and the inner wall of the circular groove 31 respectively;

[0023] In this embodiment, the spring 33 can apply an upward thrust to the push block 32, so that the push block 32 automatically moves upward and resets after losing the external force constraint, and the operator does not need to perform other operations.

[0024] In a further preferred embodiment of the present invention, Figure 2As shown, the top side of the push block 32 is arranged in an arc shape, and a soft pad 34 is fixedly mounted on the top side of the push block 32, and the arc surface of the top side of the soft pad 34 is the same as the arc surface of the bottom side of the spherical block 2;

[0025] In this embodiment, when the spring 33 pushes the push block 32 upward, the soft pad 34 can be driven to fit tightly with the bottom of the spherical block 2. Due to the thrust of the spring 33, the soft pad 34 and the bottom of the spherical block 2 generate a moving resistance force, thereby generating a large friction force between the soft pad 34 and the spherical block 2, constraining the spherical block 2 so that the spherical block 2 will not rotate on its own when not subjected to a large external force.

[0026] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, an annular groove 35 is formed on the outer peripheral wall of the push block 32, a sealing ring 36 is provided in the annular groove 35, and the outer peripheral wall of the sealing ring 36 contacts the inner wall of the annular groove 35 and the inner wall of the circular groove 31;

[0027] In this embodiment, the annular groove can block the gap between the push block 32 and the inner wall of the circular groove 31 . When the push block 32 moves downward, it can push out the excess gas in the bottom opening of the circular groove 31 from the bottom opening of the circular groove 31 .

[0028] In a further preferred embodiment of the present invention, Figure 2 As shown, two rectangular grooves 37 are oppositely formed in the base 12, and the two rectangular grooves 37 are oppositely formed on the outer circumferential side of the circular groove 31, the interior of the rectangular groove 37 is communicated with the interior of the circular groove 31, and a circular hole 38 is formed on the outer wall of the base 12 at a position corresponding to the rectangular groove 37, and the interior of the circular hole 38 is communicated with the interior of the corresponding rectangular groove 37;

[0029] In this embodiment, the circular hole 38 and the rectangular groove 37 can constrain and limit the movement of the push rod 39, so that the push rod 39 can only move along a vertical linear trajectory.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, a push rod 39 in an L-shaped configuration is provided in the rectangular groove 37 and the corresponding circular hole 38, and the outer peripheral wall of the push rod 39 contacts the inner wall of the corresponding rectangular groove 37 and the inner wall of the corresponding circular hole 38, one end of the push rod 39 is spherical, and the other end of the push rod 39 is fixedly connected to the push block 32, and the bottom of the push rod 39 is a square rod;

[0031] In this embodiment, the downward movement of the push block 32 is achieved by the operator pressing the push rod 39 downward, and the fit between the push rod 39 and the inner wall of the rectangular groove 37 can prevent the gas at the upper and lower ends of the push block 32 from exchanging gas through the rectangular groove 37. In the process of the push block 32 pushing the gas in the bottom opening of the circular groove 31 out, the gas on the bottom side of the push block 32 will not move from the rectangular groove 37 over the push block 32 to above the push block 32. At the same time, in the process of the push block 32 moving upward, the gas above the soft pad 34 will not move from the rectangular groove 37 over the push block 32 to below the push block 32, but will only be discharged from the base 12 through the gap between the spherical block 2 and the base 12.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, a storage groove 312 in the shape of an annular arrangement is provided on the bottom side of the base 12, a soft annular tube 313 is provided in the storage groove 312, and the outer peripheral wall of the soft annular tube 313 is in contact with the inner wall of the storage groove 312, and the bottom side of the soft annular tube 313 extends to the outside of the storage groove 312;

[0033] In this embodiment, after placing the base 12 on the desktop, the operator presses the base 12 downward, and the bottom tube of the soft ring is adaptively deformed according to the contact with the desktop, so that the bottom of the soft ring tube 313 fits tightly with the desktop, blocking the gap between the base 12 and the desktop.

[0034] Working principle: When connecting the PLC and the antenna 1, the operator first holds the base 12 and presses the push rod 39 with his fingers, and pushes the push block 32 toward the opening of the circular groove 31 through the push rod 39 to discharge the excess gas in the bottom opening of the circular groove 31. Then the operator places the base 12 on the external desktop and presses the base 12 downward. At this time, the bottom tube of the soft ring is adaptively deformed according to the contact with the desktop, so that the bottom of the soft ring tube 313 fits tightly with the desktop, so that a closed space is formed in the bottom opening of the circular groove 31. Then the operator releases the pressure of the push rod 39. Due to the push of the spring 33 on the push block 32, the push ring moves up and resets. At this time, a closed negative pressure space is formed in the opening of the circular groove 31, so that the base 12 is adsorbed on the desktop. At this time, the antenna 1 is stably placed on the desktop;

[0035] After the base 12 is turned dark, the operator installs the connecting wire on the device body 11 and connects it to the PLC. Then the operator pushes the push block 32 downward through the push rod 39 according to the above-mentioned method until the soft pad 34 is separated from the spherical block 2. Then the operator rotates the device body 11 through the spherical block 2 to adjust the inclination angle of the antenna 1 until the PLC signal is well connected. Then the pressure of the push rod 39 is released, and the push rod 39 pushes the push block 32 to move up and reset, and makes the soft pad 34 fit tightly with the bottom of the spherical block 2. Due to the push of the spring 33 on the push block 32, the contact force between the soft pad 34 and the outer wall of the spherical block 2 is large, thereby generating a great friction force between the soft pad 34 and the spherical block 2, and the spherical block 2 is positioned and constrained by the friction force, so that the inclination angle of the device body 11 remains stable.
