[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 7 As shown, an anti-static door handle proposed in an embodiment of the present application includes two mounting plates 1, and a plurality of mounting holes 2 are opened on the mounting plates 1. The mounting holes 2 are countersunk holes for passing screws. There are four mounting holes 2 and they are distributed in a rectangular shape. A hand-held rod 3 is installed between the two mounting plates 1. A flexible wire 4 is connected to one of the mounting plates 1. A wiring terminal 5 is installed at the free end of the flexible wire 4. The wiring terminal 5 is used for grounding. When in use, if the door frame is grounded, the wiring terminal 5 can be connected to the door frame after the two mounting plates 1 are installed on the door. The flexible wire 4 is spiral-shaped and has a certain length, which does not affect the normal opening of the door. When a person holds the hand-held rod 3 and needs to open or close the door, the current will enter the mounting plate 1 from the hand-held rod 3, and then flow to the flexible wire 4 and then connect to the ground from the wiring terminal 5, thereby guiding the current to the ground, effectively preventing static electricity and further improving safety.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, a plug-in slot 6 is opened on one side of one of the mounting plates 1, a conductive plate 7 is inserted in the plug-in slot 6, and a connector 8 for fixing the conductive plate 7 is installed on the mounting plate 1. The connector 8 is designed so that when the flexible wire 4 needs to be replaced, the conductive plate 7 can be pulled out of the plug-in plate through the connector 8, thereby facilitating the replacement of the flexible wire 4.

[0027] like Figure 7 As shown, in some embodiments, the connecting member 8 includes a metal screw 9 threaded into the mounting plate 1, a through hole 10 is opened on the conductive plate 7, one end of the metal screw 9 passes through the through hole 10 and abuts against the plug-in slot 6, and the metal screw 9 is screwed into the mounting plate 1 and passes through the through hole 10, thereby positioning the conductive plate 7 located in the plug-in slot 6.

[0028] like Figure 7 As shown, in some embodiments, one end of the metal screw 9 is located outside the external plug-in slot 6, and the threaded sleeve is provided with a nut 24, which abuts against the mounting plate 1. In order to prevent the metal screw 9 from accidentally rotating, the nut 24 can be screwed in so that the nut 24 abuts against the mounting plate 1, thereby preventing the metal screw 9 from accidentally rotating. One end of the metal screw 9 is located outside, which is convenient for detecting the resistance of the grounding wire.

[0029] like Figure 4 and Figure 7 As shown, in some embodiments, a metal rod 23 is constructed on one side of the conductive plate 7, one end of the flexible wire 4 is connected to the metal rod 23, and a rubber sheath 11 is sheathed on the outer periphery of the flexible wire 4. The design of the rubber sheath 11 can effectively protect the flexible wire 4 and prevent the flexible wire 4 from being accidentally damaged.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the hand-held rod 3 is Π-shaped, and a storage groove 12 is provided on the hand-held rod 3. The storage groove 12 has a horizontal section and a vertical section. The horizontal section of the storage groove 12 is located on the side of the hand-held rod 3 away from the mounting plate 1, and the vertical section of the storage groove 12 is located on one side of the vertical sections of the hand-held rod 3. A blocking plate 13 is rotatably installed on the horizontal section of the storage groove 12. The blocking plate 13 blocks the storage groove 12, and the blocking plate 13 is flush with the surface of the hand-held rod 3. A locking piece 14 is installed on the blocking plate 13, and the blocking plate 13 is fixed to the hand-held rod 3 by the locking piece 14. In order to prevent the flexible wire 4 from being damaged during transportation of the hand-held rod 3, the flexible wire 4 can be placed in the storage groove 12, and then the blocking plate 13 is rotated to block the storage groove 12, and then the blocking plate 13 is fixed to the hand-held rod 3 by the locking piece 14, thereby protecting the flexible wire 4. When the hand-held rod 3 is in use, the flexible wire 4 can be placed in the storage groove 12 for backup.

[0031] like Figure 4 and Figure 6 As shown, in some embodiments, the locking member 14 includes a convex plate 15 constructed on the blocking plate 13, a mounting groove 16 is opened on the convex plate 15, a rotating plate 17 is vertically rotatably installed on the mounting groove 16, an arc-shaped plug plate 18 is symmetrically constructed on the rotating plate 17, and an arc-shaped slot 19 is symmetrically opened on one of the vertical sections of the hand-held rod 3, which is used for inserting the arc-shaped plug plate 18, that is, when the blocking plate 13 blocks the back of the blocking plate 13, the rotating plate 17 can be rotated at this time so that the arc-shaped plug plate 18 is inserted in the arc-shaped slot 19, thereby effectively preventing the blocking plate 13 from rotating.

[0032] like Figure 5 and Figure 6As shown, in some embodiments, a magnetic block 20 is installed at one end inside the arc-shaped slot 19, and an arc-shaped plug rod 21 is tightly inserted into the free end of the arc-shaped plug plate 18, and a metal plate 22 is constructed on the arc-shaped plug rod 21. Preferably, a slot is opened on the rotating plate 17 to facilitate the rotation of the rotating plate 17. When the arc-shaped plug plate 18 is inserted into the arc-shaped slot 19, the metal plate 22 will contact the magnetic block 20, so that the metal plate 22 is adsorbed on the magnetic block 20, effectively preventing the arc-shaped plug plate 18 from detaching from the arc-shaped slot 19.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
