Description

Technical Field

[0001] The present invention relates to an identification sticker, and particularly to a negative pressure adsorption type desktop identity identification sticker. Background Art

[0002] An exam identity desk sticker is an identification used to confirm the identity information of examinees in an exam environment. Such desk stickers usually contain basic information of the examinees, such as name, photo, exam number, etc., and sometimes also include information such as seat number or examination room number.

[0003] Existing desk stickers currently record information on paper and are fixed to the desktop by means of glue pasting. Using glue to fix the desk sticker may cause difficulties when removing it, and often leaves glue residues that are difficult to clean on the desktop, affecting the aesthetics of the desktop, and it cannot be reused.

[0004] Therefore, the present invention designs a negative pressure adsorption type desktop identity identification sticker. Summary of the Invention

[0005] In order to overcome the disadvantage that the existing desk sticker will leave glue residues on the desktop that are difficult to clean, the present invention provides a negative pressure adsorption type desktop identity identification sticker.

[0006] A negative pressure adsorption type desktop identity identification sticker includes a housing. A rotating shell is rotatably connected to the top of the housing. An identification sticker electronic screen is fixedly connected inside the rotating shell. A rotating ring is fixedly connected to the rotating shell. A lifting frame is slidably connected to the housing. The rotating ring is threadedly connected to the lifting frame. A first bellows is fixedly connected to the bottom of the lifting frame. A first suction cup is fixedly connected to the first bellows. The first bellows and the first suction cup are communicated through an air port. A cleaning rod is fixedly connected to the lifting frame and inserted into the air port.

[0007] In addition, particularly preferably, it further includes an air cylinder. The air cylinder is fixedly connected to one side of the housing close to the pressing plate. The air cylinder is communicated with the first bellows through an air delivery channel. A piston rod is slidably connected to the air cylinder. An elastic telescopic rod is fixedly connected between the piston rod and the air cylinder.

[0008] In addition, particularly preferably, the air delivery channel is composed of an air delivery pipe and an air delivery groove formed in the lifting frame. The air delivery groove in the lifting frame is communicated with the first bellows. The air delivery pipe is communicated between the air delivery groove in the lifting frame and the air cylinder.

[0009] In addition, particularly preferably, it further includes a pressing plate for pushing the piston rod to move. The pressing plate is fixedly connected to one side of the rotating ring.

[0010] In addition, particularly preferably, the outer side of the pressing plate is provided with an inclined surface that gradually changes outward along the arc of its edge. The pressing plate contacts the piston rod through the inclined surface.

[0011] In addition, it is particularly preferable that a fixing frame is further included. The fixing frame is fixedly connected to the lifting frame, and second bellows pipes symmetrically distributed along the fixing frame are fixedly connected to the fixing frame. The second bellows pipes communicate with second suction cups. The second suction cups penetrate downward through the bottom of the housing and are slidably connected to the housing.

[0012] In addition, it is particularly preferable that a prompting frame symmetrically distributed along the housing is further included. The prompting frame is rotatably connected inside the housing. Guide rails symmetrically distributed along the housing are fixedly connected inside the housing. A sliding block for pushing the adjacent prompting frame to rotate is slidably connected to the guide rails. A spring is fixedly connected between the sliding block and the adjacent guide rail. The housing is provided with a prompting opening corresponding to the prompting frame, and the prompting surface of the prompting frame faces the prompting opening.

[0013] In addition, it is particularly preferable that the sliding block contacts the lifting frame, and the contact surface of the lifting frame is arranged as an inclined surface.

[0014] In addition, it is particularly preferable that the sliding block is provided with an activity groove, and the sliding block is movably connected to the adjacent prompting frame through the activity groove.

[0015] In addition, it is particularly preferable that a plurality of friction blocks are further included. The friction blocks are fixedly connected to the bottom of the housing. Advantageous Effects

[0016] In the present invention, the basic information of candidates, such as name, photo, examination number, etc., is displayed on the identification sticker electronic screen. By rotating the rotating shell, the present identification sticker can be adsorbed and fixed on the desktop, and can be removed by reversing, with simple and convenient operation. Moreover, there will be no glue residue on the desktop that is difficult to clean, ensuring the beauty of the desktop, and it can also be reused, reducing costs and increasing efficiency.

[0017] When the present identification sticker is removed by reversing in the present invention, the cleaning rod will also move downward along with the lifting frame to poke out the sundries in the air inlet, achieving the effect of automatically cleaning the air inlet and preventing the air inlet from being blocked.

[0018] When the rotating shell is rotated in the present invention to enable the first suction cup to adsorb on the desktop, the gas in the first bellows pipe is also pumped into the air cylinder through the air delivery pipe. In this way, the negative pressure effect is enhanced. Moreover, on the basis of the central adsorption effect of the first suction cup, the second suction cups perform auxiliary adsorption from the front, back, left, and right corners to enhance the adsorption effect.

[0019] When the first suction cup or the second suction cup intakes air and loses the adsorption effect in the present invention, the prompting surface of the prompting frame will automatically turn to the prompting opening. In this way, it can be observed that the present identification sticker is not firmly adsorbed and needs to be re-adsorbed. Description of the Drawings

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0034] Example 1: A negative pressure adsorption type desktop identity label, as Figures 1 - 6 shown, includes a housing 101. Friction blocks 501 are fixedly connected to the front, rear, left, and right sides of the bottom of the housing 101, which are used to enhance the friction between this label and the desktop and prevent the label from sliding randomly. A rotating shell 102 is rotatably connected to the top of the housing 101 with the center as the axis. An identification label electronic screen 103 is fixedly connected inside the rotating shell 102, and the identification label electronic screen 103 displays the basic information of the examinee, such as name, photo, examination number, etc. A rotating ring 104 is fixedly connected to the middle of the bottom side of the rotating shell 102. The rotating ring 104 is provided with a spiral groove. A lifting frame 105 is slidably connected in the middle of the housing 101 in the up and down direction. The rotating ring 104 is threadedly connected to the lifting frame 105 through the spiral groove. A first corrugated pipe 106 is fixedly connected to the bottom of the lifting frame 105. A first suction cup 107 is fixedly connected to the bottom of the first corrugated pipe 106. The first corrugated pipe 106 and the first suction cup 107 are communicated through an air port. A cleaning rod 108 is fixedly connected to the middle of the bottom of the lifting frame 105, and the cleaning rod 108 is inserted into the air port.

[0035] This is a negative pressure adsorption type identity label that can be adsorbed on the desktop. The specific adsorption operation is as follows: Rotate the rotating shell 102. The rotating shell 102 drives the identification label electronic screen 103 and the rotating ring 104 to rotate. The rotating ring 104 drives the lifting frame 105 to slide upward through the spiral groove, thereby stretching the first corrugated pipe 106 upward. The cleaning rod 108 moves upward with the lifting frame 105. In this way, the air between the first suction cup 107 and the desktop is sucked into the first corrugated pipe 106 from the air port under the action of negative pressure, and then this label can be adsorbed and fixed on the desktop.

[0036] The operation to remove this label is as follows: Reverse-rotate the rotating shell 102. The rotating shell 102 drives the identification label electronic screen 103 and the rotating ring 104 to rotate in the reverse direction. The rotating ring 104 drives the lifting frame 105 to slide downward through the spiral groove. The first corrugated pipe 106 returns downward. The gas in the first corrugated pipe 106 is discharged through the air port. The cleaning rod 108 moves downward with the lifting frame 105 to poke the sundries in the air port outward, achieving the effect of automatically cleaning the air port and preventing the air port from being blocked.

[0037] As Figure 7 and Figure 8As shown in the figure, it further includes a pressing plate 201. The pressing plate 201 is fixedly connected to the outer right side of the rotating ring 104. The outer side of the pressing plate 201 is provided with an inclined surface that gradually changes outward along its edge arc. A cylinder 202 is fixedly connected to the right side inside the housing 101. The cylinder 202 is communicated with the first bellows 106 through an air delivery channel. The air delivery channel is composed of an air delivery pipe 203 and an air delivery groove opened in the lifting frame 105. The air delivery groove in the lifting frame 105 is communicated with the first bellows 106. The air delivery pipe 203 is communicated between the air delivery groove in the lifting frame 105 and the cylinder 202. A piston rod 204 is slidably connected to the left part of the cylinder 202 in the left-right direction. The pressing plate 201 contacts the piston rod 204 through the inclined surface. When the pressing plate 201 rotates counterclockwise, the piston rod 204 is extruded to slide rightward through the inclined surface. An elastic telescopic rod 205 is fixedly connected between the piston rod 204 and the cylinder 202.

[0038] When the rotating ring 104 rotates, it drives the pressing plate 201 to rotate counterclockwise. The pressing plate 201 extrudes the piston rod 204 to slide rightward relative to the cylinder 202. The elastic telescopic rod 205 is compressed. The gas in the first bellows 106 is pumped into the cylinder 202 through the air delivery pipe 203. In this way, the negative pressure effect is enhanced, and the first suction cup 107 is accelerated to adsorb on the tabletop. When the rotating ring 104 rotates in reverse, it drives the pressing plate 201 to rotate clockwise. The pressing plate 201 no longer extrudes the piston rod 204, and the elastic telescopic rod 205 resets to drive the piston rod 204 to slide leftward.

[0039] As Figure 9 and Figure 10 As shown in the figure, it further includes a fixing frame 301. The fixing frame 301 is fixedly connected to the lifting frame 105. Both the front and rear sides of the fixing frame 301 are fixedly connected with second bellows 302 that are symmetrically distributed along the left and right of the fixing frame 301. The bottom of the second bellows 302 is communicated with a second suction cup 303. The second suction cup 303 penetrates downward through the bottom of the housing 101, and the second suction cup 303 is slidably connected to the housing 101.

[0040] The up and down movement of the lifting frame 105 drives the up and down movement of the fixing frame 301. When the fixing frame 301 moves upward, the second bellows 302 is stretched. The air between the second suction cup 303 and the tabletop is sucked into the second bellows 302 under the negative pressure effect. In this way, on the basis of the central adsorption effect of the first suction cup 107, the second suction cup 303 performs auxiliary adsorption from the front, back, left, and right corners to enhance the adsorption effect. When the fixing frame 301 moves downward, the second bellows 302 resets accordingly.

[0041] Embodiment 2: On the basis of Embodiment 1, as Figure 11 and Figure 12As shown in the figure, it further includes a prompt rack 401 symmetrically distributed before and after along the outer shell 101. The prompt rack 401 is rotatably connected to the inside of the outer shell 101. Inside the outer shell 101, there are guide rails 402 symmetrically distributed before and after along the outer shell 101. The guide rails 402 are slidably connected with sliding blocks 403 in the front-back direction. The sliding blocks 403 are in contact with the lifting frame 105, and the contact surface of the lifting frame 105 is set as an inclined surface. The sliding blocks 403 are provided with movable grooves, and the sliding blocks 403 are movably connected to the adjacent prompt racks 401 through the movable grooves. A spring 404 is fixedly connected between the sliding blocks 403 and the adjacent guide rails 402. The outer shell 101 is provided with a prompt opening 405 corresponding to the prompt rack 401, and the prompt surface of the prompt rack 401 faces the prompt opening 405.

[0042] When the lifting frame 105 moves upward, it squeezes the sliding block 403 along the guide rail 402 to slide toward the side where the spring 404 is stretched through the inclined surface. The sliding block 403 pushes the prompt rack 401 to rotate through the movable groove, so that the prompt surface of the prompt rack 401 turns away from the prompt opening 405. If the first suction cup 107 or the second suction cup 303 intakes air and loses the adsorption effect, the lifting frame 105 moves downward to reset. The sliding block 403 is no longer squeezed by the inclined surface of the lifting frame 105. Therefore, under the reset action of the spring 404, it slides reversely to reset. When the sliding block 403 slides reversely, it pulls the prompt rack 401 to reverse through the movable groove, so that the prompt surface of the prompt rack 401 turns to the position of the prompt opening 405. In this way, it can be observed that this label sticker is not firmly adsorbed and needs to be adsorbed again.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
