Description

Technical Field

[0001] The present application relates to the field of digital tubes, and in particular to a digital tube that is easy to assemble and disassemble. Background Art

[0002] A digital tube, also known as a glow tube, is an electronic device that can display numbers and other information. The glass tube includes an anode made of a metal mesh and multiple cathodes. Most digital tube cathodes are in the shape of numbers. The tube is filled with low-pressure gas, usually mostly neon with some mercury and / or argon. When one of the cathodes is charged, the digital tube will emit colored light, depending on the gas in the tube, usually orange or green. LED digital tubes (LED Segment Displays) are devices composed of multiple light-emitting diodes packaged together to form an "8" shape. The leads have been connected internally, and only their strokes and common electrodes need to be led out. The commonly used segments of LED digital tubes are generally 7 segments, and some have an additional decimal point.

[0003] A digital tube generally includes a plastic shell, in which an LED lamp is encapsulated, and a display screen that matches the LED lamp is installed outside the plastic shell. A protective film will be attached to the outside of the display screen. The pins of the LED lamp will pass through the plastic shell for connection with the PCB board. After the digital tube is assembled, it needs to be tested. The test includes appearance testing, such as whether the display screen is cracked, and lamp bead testing, such as whether the lamp bead emits light after power is turned on. For digital tubes that fail the test, the unqualified display screen or lamp bead needs to be removed and replaced. At present, most digital tubes use card slots to install the display screen for good appearance. The gap between the display screen and the shell is small, which makes it difficult to disassemble the display screen. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0028] The present application discloses a digital tube which is easy to disassemble and assemble. Figure 1 As shown, it includes a box body 1, an LED lamp bead 2 is arranged inside the box body 1, a display screen 3 for matching with the LED lamp bead 2 is arranged on the top of the box body 1, two mounting blocks 4 are fixedly connected to the bottom surface of the display screen 3, and the two mounting blocks 4 are respectively located on two opposite sides of the display screen 3, and slots 5 corresponding to the mounting blocks 4 are opened on the two outer sides of the box body 1, and mounting holes 6 are opened through the mounting blocks 4, and first screw holes are opened on the slots 5 accordingly, and the mounting blocks 4 are fixed in the slots 5 by the cooperation of bolts, the mounting holes 6 and the first screw holes. The design of the mounting blocks 4 on the side of the display screen 3 allows the staff to remove the display screen 3 by only loosening the bolts from the side of the box body 1, and the display screen 3 can be easily removed from the side, and then the display screen 3 can be disassembled without affecting the internal structure of the box body 1, so that the disassembly, assembly and replacement of the display screen 3 and the LED lamp bead 2 can be conveniently performed.

[0029] Specifically, Figure 1 and Figure 2 As shown, one end of one of the mounting blocks 4 for inserting into the slot 5 is specifically configured to be semicircular, and the other end of the mounting block 4 for inserting into the slot 5 is specifically configured to be in an inverted trapezoidal shape. The shape of the slot 5 matches the corresponding mounting block 4. Since it is difficult to determine the direction of the display screen 3 from the front of the display screen 3 when the display screen 3 is not powered on, the shapes of the two mounting blocks 4 are respectively configured to be semicircular and inverted trapezoidal, so that when the display screen 3 is installed, the two mounting blocks 4 need to be aligned with the corresponding slots 5, so that the installation direction of the display screen 3 can be quickly determined, and the reverse installation of the display screen 3 can be reduced. In addition, the semicircular and inverted trapezoidal mounting blocks 4 have a guiding effect when the mounting blocks 4 are inserted into the slots 5, which is more convenient for installation and quick alignment with the slots 5, and is conducive to making the installation position of the display screen 3 more accurate. The two mounting holes 6 are both configured to be stepped holes. The mounting holes 6 are used to cooperate with the heads of the bolts. When the mounting blocks 4 are locked with bolts, the heads of the bolts can be completely immersed in the mounting holes 6.

[0030] like Figure 3 and Figure 4As shown, a PCB board 11 is provided at the bottom of the box body 1, and a mounting ear 12 is provided on the side wall of the box body 1. In this embodiment, two mounting ears 12 are respectively located at two diagonal positions of the box body 1, and a through hole 13 is provided on the mounting ear 12. A second screw hole is provided on the PCB board 11. The PCB board 11 is installed at the bottom of the box body 1 by connecting the second screw hole and the mounting ear 12 through a bolt. A plurality of connecting pins 14 are provided on the bottom surface of the PCB board 11. The PCB board 11 integrates the connection of each LED lamp bead 2. At the same time, the PCB board 11 is connected to the second screw hole through the bolt passing through the mounting ear 12, so that the PCB board 11 is installed at the bottom of the box body 1, which is also convenient for disassembling the PCB board 1.

[0031] In addition, if Figure 5 and Figure 6 As shown, a packaging block 7 is provided in the box body 1, and two first jacks 8 are formed on both sides of the packaging block 7, and a column 15 corresponding to the first jack 8 is provided on the PCB board 11, and the column 15 is used to be inserted into the first jack 8, so that the packaging block can be detachably installed on the PCB board 11, and the LED lamp bead 2 is installed on the packaging block 7, and a plurality of second jacks 9 for inserting pins are formed on the packaging block 7. The pins of the LED lamp beads 2 are used to pass through the second jacks 9 and are placed at the bottom of the box body 1. The setting of the packaging block 7 facilitates the disassembly of the packaging block 7 and the LED lamp beads 2 as a whole, and the setting of multiple second jacks 9 allows the pins of the LED lamp beads 2 to be inserted into different second jacks 9 respectively for connection with the PCB board 11, which is beneficial to avoid the occurrence of pin entanglement. A plurality of display holes 10 are provided at the bottom of the display screen 3. The display holes 10 correspond to the LED lamp beads 2. In this embodiment, the display holes 10 specifically include long strip holes for forming numbers and circular holes for serving as decimal points. Different LED lamp beads 2 correspond to different display holes 10, so that the light emitted by a single LED lamp bead 2 can be emitted from its corresponding single display hole 10, reducing the light interference between the LED lamp beads 2 and making the display effect better.

[0032] The implementation principle of this embodiment is:

[0033] When it is necessary to remove the display screen 3, the staff only needs to loosen the bolts from the side of the box body 1 to take out the display screen 3 upwards, and the mounting block 4 is disengaged from the slot 5, so that the display screen 3 can be removed without affecting the internal structure of the box body 1. When it is necessary to remove the entire LED lamp bead 2, it is only necessary to remove the bolts in the first sockets 8 on both sides of the packaging block 7, so that the LED lamp bead 2 can be removed as a whole.
