Description

Technical Field

[0001] The utility model relates to the technical field of digital tubes, in particular to an anti-loosening LED digital tube. Background Art

[0002] A Nixie tube, also known as a Nixie tube, is an electronic device that can display numbers and other information. It consists of a glass tube containing a wire mesh anode and multiple cathodes. Most Nixie tubes have cathodes shaped like numbers. The tube is filled with a low-pressure gas, typically neon with some mercury and / or argon. When a charge is applied to one of the cathodes, the tube emits a color, depending on the gas inside the tube, typically orange or green.

[0003] When using a digital tube, its pins need to be connected so that the digital tube can work normally. However, existing digital tubes generally insert the pins into the circuit board and connect to the circuit using soldering or other methods. Since the digital tube has many pins and is not additionally fixed, uneven force is easily applied during use, resulting in pin desoldering and poor contact. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] Reference Figures 1 to 2 To achieve the above-mentioned purpose, the utility model proposes an anti-loosening LED digital tube, which includes a digital tube body. The upper end of the digital tube body is connected to an upper bracket 1, and the lower end is connected to a lower bracket 2. The upper bracket 1 and the lower bracket 2 are wrapped around the digital tube body; the inner wall of the upper bracket 1 is provided with a mounting cavity 11, and the outer edge of the upper bracket 1 facing the mounting cavity 11 is covered with a locking portion 12. The top of the upper bracket 1 is provided with a limiting portion 14 protruding toward the mounting cavity 11, and the end surface of the bottom of the upper bracket 1 facing away from the mounting cavity 11 is provided with a plurality of bracket hooks 16, and the bracket hooks 16 are located below the locking portion 12; the peripheral edge of the lower bracket 2 is connected to the locking portion 12, and the locking portion 12, the limiting portion 14, and the lower bracket 2 enclose a mounting space for fixing the digital tube body.

[0028] By setting a limit portion 14 on the upper end surface of the upper bracket 1 facing the installation cavity 11, the upper part of the digital tube body can be quickly limited to prevent the digital tube from falling out of the upper bracket 1, and the lower bracket 2 can facilitate the passage of the digital tube pins and limit the digital tube to prevent the digital tube from falling out of the bracket from below. In addition, the lower bracket 2 can be easily locked by various structures such as bolts and clip structures through the locking portion 12 set on the upper bracket 1, which is convenient for installation or disassembly, and at the same time makes the entire bracket structure easy to maintain.

[0029] The outer wall of the upper bracket 1 extends in a direction away from the limiting portion 14, and the extended part is protruding with a bracket hook 16 away from the installation cavity 11. The bracket hook 16 is located below the lower bracket 2. The extended part has a certain elasticity and can be easily locked in conjunction with the bracket hook 16, which can effectively prevent the digital tube from loosening after installation. The entire structure has high strength and can be installed more conveniently.

[0030] See also Figure 2 In one embodiment of the present application, a connecting groove 13 is defined between the locking portion 12 and the inner wall of the bracket hook 16 , and the connecting groove 13 surrounds the locking portion 12 .

[0031] By providing a connecting groove 13 on the end face of the locking portion 12 facing the bracket hook 16, the end of the lower bracket 2 can be easily inserted into the connecting groove 13, and the lower bracket 2 can be clamped through the connecting groove 13. As the first-level locking structure of the lower bracket 2, it can be easy to install, and at the same time make the installed bracket stronger, which can better ensure the stability of the LED digital tube.

[0032] See also Figure 2 In one embodiment of the present application, the lower bracket 2 includes a connecting portion 21, a sealing portion 23 and a locking portion 24. The connecting portion 21 is formed by folding the end of the lower bracket 2. The connecting portion 21 is passed through the connecting groove 13 and abuts against the inner wall of the locking portion 12 and the bracket hook 16; the sealing portion 23 is connected to the connecting portion 21 and abuts against the bottom edge of the locking portion 12; the locking portion 24 is connected to the sealing portion 23 and is arranged facing the installation cavity 11, and the pins of the digital tube body are passed through the locking portion 24.

[0033] The lower bracket 2 is made of relatively flexible and insulating plastic, rubber, silicone and other materials. The connecting part 21 has a certain elasticity by being folded, and can be easily inserted into the connecting groove 13. At the same time, the elasticity enables the connecting part 21 to support the inner wall of the connecting groove 13 to ensure initial fixation and prevent the LED digital tube from loosening.

[0034] The sealing portion 23 is the transition portion between the connecting portion 21 and the locking portion 24. The locking portion 24 is used for abutment and supports the LED digital tube to ensure its installation stability. The sealing portion 23 is at the corner position of the locking portion 12, which can maintain a seal between the lower bracket 2 and the upper bracket 1, and can better protect the digital tube.

[0035] See also Figure 2 In one embodiment of the present application, the locking portion 24 is provided with a buffer portion 25 protruding toward the installation cavity 11 . The buffer portion 25 passes through the installation cavity 11 and is connected to the bottom of the digital tube body.

[0036] The locking portion 24 protrudes toward the installation cavity 11 by the buffer portion 25. Since the lower bracket 2 is made of a flexible and insulating material, the buffer portion 25 can enable the locking portion 24 to lock the digital tube body to prevent it from loosening. The buffer portion 25 can also reduce the pressure on the digital tube body to avoid damage to the digital tube body. The buffer portion 25 can also make the locking portion 24 easy to deform, so that LED digital tubes of different specifications can be easily installed.

[0037] See also Figures 1 to 2 In one embodiment of the present application, a mounting hole 17 is provided at the end of the upper bracket 1 away from the bracket hook 16 , and the bolt abuts against the connecting portion 21 through the mounting hole 17 .

[0038] The bolts can abut against the connection part 21 through the mounting holes 17, so that the connection part 21 is subjected to a stronger pressure, can be better sealed, and is easy to install.

[0039] See also Figure 2 In one embodiment of the present application, a matching hole 22 is formed on the connecting portion 21 facing the mounting hole 17 , and a bolt is passed through the mounting hole 17 and the matching hole 22 and abuts against the lower bracket 2 .

[0040] The connecting part 21 is provided with a matching hole 22 toward the mounting hole 17. The bolt can directly clamp part of the connecting part 21 through the matching hole 22, and press the remaining connecting part 21 against the locking part 12 to prevent the lower bracket 2 from loosening. The entire structure can be easy to install and has considerable strength, which can easily protect the LED digital tube.

[0041] See also Figures 1 to 2 In one embodiment of the present application, a light-transmitting portion 15 is provided on the end surface of the limiting portion 14 facing away from the installation cavity 11 , and the height of the light-transmitting portion 15 gradually decreases in a direction away from the locking portion 12 .

[0042] The end surface of the limiting portion 14 away from the digital tube body is provided with a radial groove, which can avoid blocking the light emitted by the LED digital tube, so that the bracket can protect the LED digital tube while making the digital tube easy to use.
