DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described in the present application are part of the embodiments of the present application, rather than all the embodiments.

[0024] As shown in the drawings, the present embodiment provides a screen dust removal tool, which comprises a guide assembly 10 and a cleaning piece 20. Figures 1-5 Specifically, as shown in the drawings, the guide assembly 10 comprises a vertically arranged bidirectional adjusting rod 11 and guide pieces symmetrically arranged at both ends of the bidirectional adjusting rod 11. The inner wall of the bidirectional adjusting rod 11 is hollow, and threaded holes with opposite rotation directions are arranged at both ends of the bidirectional adjusting rod 11. The guide pieces are threadedly connected with the bidirectional adjusting rod 11, and the cross section of the outer wall of the bidirectional adjusting rod 11 is in a rectangular structure. When the distance between the guide pieces at both ends of the bidirectional adjusting rod 11 needs to be adjusted, the bidirectional adjusting rod 11 can be rotated to achieve the adjustment. The rectangular cross section makes it convenient to grip the bidirectional adjusting rod 11 when it is rotated, and it is not easy to slip, so the adjustment is convenient.

[0025] Figures 2-3 The guide piece comprises a vertical rod 12, a clamping seat 13 and a limiting seat 14. The threaded section 121 is arranged at one end of the vertical rod 12 which is connected with the bidirectional adjusting rod 11. The clamping seat 13 is vertically arranged at the other end of the vertical rod 12 and extends to one side of the vertical rod 12. The limiting seat 14 is parallelly and spacedly arranged at one side of the other end of the vertical rod 12, so that one end of the guide piece forms a concave structure. The other end of the vertical rod 12 is provided with a limiting ring 122 which is spacedly arranged above the clamping seat 13. The third rubber wheel 123 is rotatably arranged between the limiting ring 122 and the clamping seat 13, and is used for rolling contact with one side of the display screen 1. The top surface of the clamping seat 13 is rotatably provided with the first rubber wheel 131 which is used for rolling contact with the upper and lower edges of the display screen 1. The limiting seat 14 is rotatably provided with the second rubber wheel 141 on the side facing the vertical rod 12. The axis of the second rubber wheel 141 is perpendicular to the axis of the first rubber wheel 131, and is used for rolling contact with the other side of the display screen 1. The clamping seat 13 is outwardly provided with the convex seat 132 at one side, and the two ends of the cleaning piece 20 are rotatably connected with the convex seat 132.

[0026] The guide piece comprises a vertical rod 12, a clamping seat 13 and a limiting seat 14. The threaded section 121 is arranged at one end of the vertical rod 12 which is connected with the bidirectional adjusting rod 11. The clamping seat 13 is vertically arranged at the other end of the vertical rod 12 and extends to one side of the vertical rod 12. The limiting seat 14 is parallelly and spacedly arranged at one side of the other end of the vertical rod 12, so that one end of the guide piece forms a concave structure. The other end of the vertical rod 12 is provided with a limiting ring 122 which is spacedly arranged above the clamping seat 13. The third rubber wheel 123 is rotatably arranged between the limiting ring 122 and the clamping seat 13, and is used for rolling contact with one side of the display screen 1. The top surface of the clamping seat 13 is rotatably provided with the first rubber wheel 131 which is used for rolling contact with the upper and lower edges of the display screen 1. The limiting seat 14 is rotatably provided with the second rubber wheel 141 on the side facing the vertical rod 12. The axis of the second rubber wheel 141 is perpendicular to the axis of the first rubber wheel 131, and is used for rolling contact with the other side of the display screen 1. The clamping seat 13 is outwardly provided with the convex seat 132 at one side, and the two ends of the cleaning piece 20 are rotatably connected with the convex seat 132. ​

[0027] The cleaning component 20 includes a rotating shaft 21, and a soft brush 22 is provided on the outer periphery of the rotating shaft 21. Both ends of the rotating shaft 21 are rotatably connected to the boss 132.

[0028] In use, the concave parts of the guides at both ends of the bidirectional adjustment rod 11 are respectively engaged with the upper and lower sides of the display screen 1. The bidirectional adjustment rod 11 is rotated so that the vertical rods 12 at both ends move in opposite directions, thereby causing the first rubber wheel 131 to abut against the upper and lower sides of the display screen 1, and the soft brush 22 on the outer wall of the rotating shaft 21 to adhere to one side of the display screen 1, so that the third rubber wheel 123 abuts against the upper and lower sides of one side of the display screen 1 respectively. It is worth noting that the projection position of the cross section of the rotating shaft 21 in the height direction of the display screen 1 is located between the display screen and the vertical rod 12, so as to avoid the diameter of the third rubber wheel 123 being too large, which would prevent the soft brush 22 on the outside of the rotating shaft 21 from contacting the display screen 1 and causing cleaning failure.

[0029] The second rubber wheel 141 abuts against the back of the display screen 1. Finally, one of the vertical rods 12 is pushed along the length of the display screen 1, thereby moving the rotating shaft 21 along the length of the display screen 1, so that the soft brush 22 can clean the display screen 1 with dust. This is not only convenient to operate, but also highly efficient.

[0030] Preferably, in order to ensure that the third rubber wheel 123 only rotates circumferentially and does not move axially during the cleaning process, a limiting ring 122 is provided at the other end of the vertical rod 12, so that the third rubber wheel 123 is located between the limiting ring 122 and the card seat 13, and the diameter of the limiting ring 122 is smaller than the diameter of the third rubber wheel 123, so as to prevent the limiting ring 122 from scratching the display screen 1.

[0031] Specifically, such as Figures 4-5 As shown, a groove 133 is provided below the end of the card holder 13 away from the vertical rod 12. The length direction of the groove 133 is consistent with the length direction of the card holder 13, and the groove 133 is parallel and spaced below one end of the first rubber wheel 131. The limiting seat 14 also includes a sliding sleeve 142 with a U-shaped structure. The lower horizontal part of the sliding sleeve 142 is slidably connected to the groove 133. A first screw 134 is vertically provided on the outer side of the end of the card holder 13 away from the vertical rod 12. The first screw 134 passes through one end of the groove 133 and is threadedly connected to the other end of the groove 133. The rear section has a smooth rod structure. The lower horizontal part of the sliding sleeve 142 is slidably connected to the smooth rod of the first screw 134. A spring 135 is sleeved on the first screw 134. One end of the spring 135 abuts against the sliding sleeve 142, and the other end abuts against the outer end of the sliding groove 133. The second rubber wheel 141 is located on the side of the upper horizontal part of the sliding sleeve 142 facing the vertical rod 12, so that the second rubber wheel 141 is always kept in contact with the back of the display screen 1 under the action of the spring 135. When the display screen 1 is a concave surface, it can adapt to the concave curvature of the display screen 1 to increase the application range of the tooling.

[0032] Preferably, in order to correspond the second rubber wheel 141 with the third rubber wheel 123, the top surface of the lateral part on the upper side of the sliding sleeve 142 is provided with a square seat 143, and the second rubber wheel 141 is rotatably arranged on the side of the square seat 143 facing the vertical rod 12, so that the force points of the two sides of the display screen 1 correspond, thereby improving the stability during work.

[0033] Further preferably, in order to facilitate the disassembly and cleaning of the cleaning member 20, a connecting member 23 is rotatably arranged in the convex seat 132, one end of the connecting member 23 is connected with the rotating shaft 21 through clamping or screwing, wherein the clamping is achieved by providing connecting holes on both ends of the rotating shaft 21 and clamping grooves along the axis perpendicular to the connecting holes, and the one end of the connecting member 23 is provided with a spring pin along the axis perpendicular to the connecting member 23, so that the spring pin is clamped with the clamping groove; the screwing is achieved by providing screw holes on both ends of the rotating shaft 21, and the one end of the connecting member 23 is provided with a threaded section, so that the connecting member 23 is screwed with the rotating shaft 21, thereby facilitating the disassembly of the rotating shaft 21 and the cleaning of the soft brush 22.

[0034] The above description is only the preferred embodiments of the present application, and does not mean the only or limiting the present application. Those skilled in the art should understand that various changes or equivalent replacements made to the present application without departing from the scope of the present application, all belong to the scope of protection of the present application.
