Description

Technical area

[0001] The utility model relates to the field of financial trend technology and, in particular, to a movable economic trend plotter. Background technology

[0002] The economic and financial trend curve mainly refers to the phenomenon of economic and financial development through a large amount of data and information, and then simulates the phenomenon of economic and financial development in the form of a curve direction, so as to facilitate people to have a more intuitive understanding of financial and economic phenomena.

[0003] The display of existing economic and financial trend curves is usually achieved using economic trend curve simulation devices. Most of the existing economic trend curve simulation devices use a plurality of sliders to slide on the plate and drive the elastic rope between adjacent sliders to simulate the curve direction. This approach has some disadvantages: the number of sliders is limited, and the simulation cannot simulate complex and changing scenes. It is necessary to adjust the position of the slider according to the data, which is laborious to operate. In addition, most of the existing economic trend curve simulation devices are not equipped with a movable mechanism and are inconvenient to move.Although some devices have casters with braking functions, in practical use, it is sometimes necessary to move or rotate the direction of the economic trend curve multiple times to point people in different directions. In this case, it is necessary to brake / open each caster frequently, which is very laborious to operate. Contents of the utility model

[0016] To clarify the purpose, technical solutions, and advantages of the embodiments of the utility model, the technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the drawings in the embodiments. Obviously, the description of the embodiments is part of the embodiments of the utility model and not of all embodiments. The components of the embodiments of the utility model generally described herein and illustrated in the figures can be arranged and designed in a variety of different configurations.

[0017] Embodiment 1, in conjunction with the Fig. , a movable economic trend plotter comprises a back plate 1, a plotter body arranged on the front side of the back plate 1 and a control unit 2 with a display panel arranged on one side of the back plate 1.

[0018] At the lower end of the back plate 1 is an adjustable telescopic rod 3, to whose lower end a motor housing 4 is attached. A roller mount 5 is attached to the lower end of the motor housing 4, with rollers 6 mounted at its four corners. The motor housing 4 contains a motor 3 7, whose rotating shaft is connected to a threaded rod 8. The threaded rod 8 is screwed to a threaded tube 9, the lower end of which protrudes from the roller mount 5. A base 10 is attached to the lower end of the threaded tube 9.

[0019] On the front of the back plate 1 is a U-shaped frame 11 with a slot 12 for inserting drawing paper. The four corners of the U-shaped frame 11 are secured with clamping screws 13.

[0020] On the back of the back plate 1 there is a storage compartment 14.

[0021] During operation, the lower end of the pad 10 is higher than the lower end of the roller 6, so that the economic trend plotter can be easily moved. When the economic trend plotter does not need to be moved, it is sufficient to control the motor 3 7 via the control unit with display panel 2. The motor 3 7 drives the threaded rod 8. The threaded rod 8 moves the threaded tube 9 downward. The threaded tube 9 moves the pad 10 downward and touches the ground, thereby achieving the braking effect. The economic data is input into the control unit with display panel 2, and the plotter body is drawn. When the drawing paper is inserted into the slot 12 of the U-shaped frame 11, the clamp screw 13 is tightened to clamp the drawing paper to the end of the clamp screw 13. This prevents the drawing paper from slipping during the drawing process and ensures drawing quality.The drawn drawings can be placed in the storage compartment 14 for easy storage and later use.

[0022] In this particular embodiment, the plotter body comprises two connecting seats 1 fixedly arranged on the front side of the back plate, a threaded rod 1 rotatably connected to the two connecting seats 1, a sliding rod 1 fixedly connected to the two connecting seats 1, an adjustment block 1 screwed to the threaded rod 1, a connecting seat 2 fixedly connected to the adjustment block 1, a sliding rod 2 fixedly connected to the connecting seat 2, a threaded rod 2 rotatably connected to the connecting seat 2, an adjustment block 2 fixedly screwed to the threaded rod 2, a mounting plate fixedly connected to the adjustment block 2, a drawing pen slidably connected to the mounting plate, a U-shaped frame fixedly connected to the mounting plate, an electromagnetic push rod mounted on the U-shaped frame, a motor 1 and a motor 2.

[0023] Adjustment block 1 is slidably connected to slide rod 1. Adjustment block 2 is slidably connected to push rod 2. One end of the electromagnetic push rod is fixedly connected to the rear end of the drawing pen. Motor 1 is mounted on one of the connecting seats 1, and its rotating shaft is connected to threaded rod 1. Motor 2 is mounted on connecting seat 2, and its rotating shaft is connected to threaded rod 2.

[0024] When the plotter is running, motor 1 27 drives threaded rod 1 16 and moves adjustment block 1 18. Motor 2 28 rotates threaded rod 2 21 and moves adjustment block 2 22. This changes the position of the plotter pen 24 in the X and Y directions. The electromagnetic push rod 26 pushes the plotter pen 24 downward so that its tip touches the plotting paper, creating the economic trend chart.

[0025] In this particular embodiment, the end of the sliding rod 220 facing away from the connecting seat 219 is fixedly connected to the limit plate 29, and the threaded rod 221 is rotatably connected to the limit plate 29. The limit plate 29 prevents the adjustment block 222 from detaching from the threaded rod 221 and increases the structural stability between the sliding rod 20 and the threaded rod 221.

[0026] In this embodiment, the adjustable telescopic rod 3 is two-stage. A tightening nut 30 is mounted between adjacent rods of the adjustable two-stage telescopic rod. By loosening the tightening nut 30, the overall length of the adjustable telescopic rod 3 can be adjusted to bring the back plate 1 to a suitable height. The tightening nut 30 can then be tightened.

[0027] In this particular embodiment, a non-slip rubber pad 31 is attached to the underside of the brake pad 10. The non-slip rubber pad 31 is in contact with the ground, thus further improving braking reliability.
