A magnetic fixing block 7 is movably connected to the front outer surface of the magnetic plate surface 5. The magnetic plate surface 5 facilitates the quick fixing and flexible replacement of notices, announcements, and other paper documents by using the magnetic plate embedding groove 6 in conjunction with the magnetic fixing block 7, thus meeting the information display needs of various scenarios.

[0021] Optionally, the magnetic plate embedding groove 6 and the magnetic plate surface 5 are fixedly connected, and the magnetic plate surface 5 can be pasted into the magnetic plate embedding groove 6.

[0022] Optionally, the magnetic plate embedding groove 6 and the magnetic plate surface 5 are detachably connected. Multiple screws are provided at the four corners of the magnetic plate surface 5, and screw holes are provided on the magnetic plate embedding groove 6, so that the magnetic plate surface 5 can be connected to the magnetic plate embedding groove 6.

[0023] The magnetic suction plate 5 is movably connected to a magnetic fixing block 7 on its front outer surface. The magnetic suction plate 5 and the magnetic fixing block 7 are preferably magnetically connected. A preferred embodiment is as follows: A metal sheet 8 is fixedly connected to the rear outer surface of the magnetic fixing block 7. The metal sheet 8 can be attracted to the magnetic plate surface 5. The outer surface of the magnetic plate surface 5 is provided with a magnetic layer, and the paper is sandwiched between the metal sheet 8 and the magnetic plate surface 5. This electricity market price display device supports the electronic display screen 2 to dynamically display electricity price information through the display frame body 1.

[0024] Optionally, the electronic display screen 2 connected to the front outer surface of the display frame body 1 is configured such that screw holes are provided at the bottom of the display screen embedding groove 3, that is, at the corresponding position on the rear side of the electronic display screen 2. The electronic display screen 2 is surrounded by a bezel, without a display area. Screws with an axial direction perpendicular to the electronic display screen 2 are inserted at the four corners of the bezel, and the electronic display screen 2 and the display frame body 1 are connected by screws. However, this requires removing four screws, which is time-consuming.

[0025] Optionally, the electronic display screen 2 is attached and fixed to the display screen embedding slot 3 around its perimeter.

[0026] The preferred embodiment of the following is the second embodiment of the scheme in which the electronic display screen 2 is connected to the front outer surface of the display frame body 1.

[0027] Preferably, to facilitate the positioning and disassembly of the electronic display screen 2 onto the display screen embedding slot 3, protrusions 31 are fixed on the top, left, and right sides of the display screen embedding slot 3, respectively. The length direction of the protrusions 31 is along the thickness direction and the front-back direction of the electronic display screen 2. There is at least one protrusion 31 on each of the top, left, and right sides.

[0028] The top, left and right sides of the electronic display screen 2 are respectively provided with grooves that match the protrusions 31.

[0029] The main body 1 of the display stand has a handle hole 33 above the display screen embedding slot 3, which communicates with the display screen embedding slot 3. This makes it easy to pry the top of the electronic display screen 2 out through the handle hole 33 when disassembling the electronic display screen 2.

[0030] Example 2: like Figure 5-7As shown, to facilitate the positioning and disassembly of the electronic display screen 2 onto the display screen embedding slot 3, protrusions 31 are fixed on the top, left, and right sides of the display screen embedding slot 3, respectively. The length direction of the protrusions 31 is along the thickness direction of the electronic display screen 2. There is at least one protrusion 31 on each of the top, left, and right sides.

[0031] The top, left and right sides of the electronic display screen 2 are respectively provided with grooves that match the protrusions 31.

[0032] The main body 1 of the display stand has a handle hole 33 above the display screen embedding slot 3, which communicates with the display screen embedding slot 3. This makes it easy to pry the top of the electronic display screen 2 out through the handle hole 33 when disassembling the electronic display screen 2.

[0033] It also includes a rotating rod 10, the axis of which is arranged along the length of the display screen embedding groove 3.

[0034] The display frame body 1 has a circular rotating hole below the display screen embedding slot 3 for the rotating rod 10 to coaxially fit into, but the rotating hole is connected to the bottom surface of the display screen embedding slot 3. The rotating hole is located in the center of the bottom surface of the display screen embedding slot 3 in the front-back direction. The left end of the rotating rod 10 passes through the rotating hole and is located outside the display frame body 1. The rotating rod 10 has a circular cross-section, and the top of the circle is cut off to remove an arc shape and make a horizontal cut to form a first plane 101. The arc of the arc is smaller than that of a semicircle. Before the electronic display screen 2 extends into the display screen embedding slot 3, the first plane 101 faces upward and does not enter the display screen embedding slot 3.

[0035] The bottom of the electronic display screen 2 is provided with an arc-shaped groove. After the electronic display screen 2 extends into the display screen embedding groove 3, the rotating rod 10 is rotated 180° in the circumference so that the first plane 101 faces downward. The rotating hole and the inner wall of the arc-shaped groove contact the outer surface of the rotating rod 10 together. The rotating rod 10 is locked to the display frame body 1 by a fastener, such as a screw.

[0036] The length of the rotating rod 10 can be less than the length of the display screen embedding slot 3, and the right end of the rotating rod 10 does not exceed the right side of the display screen embedding slot 3. The left end of the rotating hole extends through the left side of the display frame body 1, making it easy for the left end of the rotating rod 10 to be located outside the display frame body 1. This makes it easy to hold the left end of the rotating rod 10 and rotate it. The rotating hole is connected to the bottom surface of the display screen embedding slot 3, and the front and rear width of the connection is equal to the width of the first plane. The cross-section of the rotating hole at the connection is the same as the cross-section of the rotating rod 10. The bottom of the electronic display screen 2 has an arc-shaped groove, and the cross-section of the arc-shaped groove is the same as the arc-shaped cross-section removed from the circular top. At the connection between the rotating hole and the display screen embedding slot 3, the arc-shaped groove and the rotating hole of the electronic display screen 2 are joined together to form a circle, and the inner diameter of the circle matches the rotating rod 10.

[0037] In use, before the electronic display screen 2 extends into the display screen embedding slot 3, the first plane 101 faces upward and does not protrude from the bottom surface of the display screen embedding slot 3. After the electronic display screen 2 extends into the display screen embedding slot 3, the rotating rod 10 is rotated 180° circumferentially so that the first plane 101 faces downward. The part of the rotating rod 10 opposite to the first plane 101 rotates to the bottom surface of the display screen embedding slot 3 and protrudes from the bottom surface of the display screen embedding slot 3. The inner wall of the rotating hole and the arc-shaped groove contact the outer surface of the rotating rod 10. In this way, the rotating rod 10 restricts the electronic display screen 2 from moving forward and backward.

[0038] Optionally, the rotating rod 10 is locked to the display frame body 1 by a screw. Only one screw is used, reducing the number of screws required in the prior art and facilitating the disassembly of the electronic display screen. The screw restricts the rotation of the rotating rod 10, and its installation position is preferably described as the screw passing through the rear handle rod 11. Optionally, the screw is located in the middle of the length of the rotating rod, with its axis perpendicular to the electronic display screen 2. The screw passes through the front outer surface of the display frame body 1 and the middle of the rotating rod, finally threaded into the interior of the display frame body 1.

[0039] Preferably, the outer layer of the rotating rod 10 is a rubber layer. This facilitates increased friction between the rotating rod and the rotating hole, ensuring tight contact between the rotating hole and the rubber layer, preventing the rotating rod from rotating freely relative to the rotating hole. This eliminates the need to use screws to fix the position of the rotating rod.

[0040] Preferably, a handle 11 is fixed to the left end of the rotating rod 10. This further facilitates rotating the rotating rod 10 by rotating the handle 11. Before installing the electronic display screen 2, manually press and adjust the position of the handle 11 so that the first plane of the rotating rod 10 faces upward.

[0041] Furthermore, a screw is threaded through the handle rod 11. After the electronic display screen 2 extends into the display screen embedding groove 3, the screw's axis is along the left and right direction. The screw locks the rotating rod 10 onto the display frame body 1. The screw is threaded to the left outer surface of the display frame body 1, which serves to position the handle rod 11 and prevent the first plane from not facing down after the handle plate 11 is rotated.

[0042] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
