Description

Technical Field

[0001] The invention relates to an array type digital tube and an assembling method thereof. 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] A traditional digital tube is a semiconductor light-emitting device whose basic unit is a light-emitting diode. It's actually composed of seven light-emitting diodes arranged in a figure-8 shape (8 plus the decimal point). These segments are represented by a, b, c, d, e, f, g, and dp.

[0004] When installing and assembling a traditional digital tube, the digital tube needs to be installed inside a light board, and then the light board is connected and fixed. When installing the light board, multiple screws are required, and holes need to be punched on the back of the light board in advance before the lamp housing can be connected to the back of the light board. However, the efficiency of the screw connection is low, and the screws are very easy to lose during use. At the same time, the connection is relatively inconvenient. Therefore, an array-type digital tube and an assembly method thereof are proposed. Summary of the Invention

[0005] The object of the present invention is to provide an array-type digital tube and an assembly method thereof to solve the problems raised in the above background technology.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: an array-type digital tube and an assembly method thereof, comprising a lamp board, a lamp housing, and a plurality of LED digital tubes, wherein two sets of circuit boards are arranged above the lamp housing, and the upper surfaces of the two sets of circuit boards are connected to a plurality of LED digital tubes, thereby realizing an array distribution of the LED digital tubes.

[0007] The cover of the lamp panel is arranged on the upper surface of the lamp housing. One side of the lamp panel is provided with a plurality of display slots. The outer side of the lamp panel is connected with a glass screen.

[0008] A double connection component is provided inside the lamp housing.

[0009] After the lamp board is connected to one side of the lamp housing, the lamp board, multiple LED digital tubes, the circuit board and the lamp housing are connected through a double connection component.

[0010] Preferably, the double connection assembly includes a screw arranged in the middle of the lamp housing, the middle of the screw is connected to a moving gear, both sides of the moving gear are connected to follower gears, one side of the follower gear is connected to an externally threaded rod, the outer periphery of the externally threaded rod is connected to an inner screw barrel, and the side of the inner screw barrel away from the externally threaded rod is connected to a positioning block.

[0011] Preferably, a channel for the positioning block to slide is provided inside the lamp housing, and a notch is provided on one side of the channel so that the positioning block can be moved out of the channel through the notch.

[0012] Preferably, a rotation groove is provided on the upper surface of the screw rod, so that the screwdriver can be connected to the screw rod through the rotation groove and rotated.

[0013] Preferably, a matching screw barrel is provided on the inner side of the lamp panel, and the matching screw barrel and the screw rod cooperate with each other.

[0014] Preferably, plug-in plates are provided on both sides of the lamp board, and a positioning groove for inserting a positioning block is provided in the middle of the plug-in plates.

[0015] Preferably, slots for inserting plug-in boards are provided on both sides of the lamp housing.

[0016] Preferably, two groups of limiting parts for positioning the circuit board are provided on one side of the lamp board, and the limiting parts include rectangular receiving columns, and the upper surface of the receiving columns is provided with limiting columns, and the radius of the receiving columns is larger than the radius of the limiting columns, so that the circuit board is connected to the upper surface of the receiving columns through the limiting columns.

[0017] Preferably, four groups of limiting cylinders are provided on one side of the lamp housing, and the positions of the four groups of limiting cylinders and the limiting posts correspond to each other, so that the limiting cylinders are connected to the outer circumference of the limiting posts.

[0018] A method for assembling an array-type digital tube includes the following steps:

[0019] Step A: Solder one set of LED digital tubes to the upper surface of the circuit board, and then solder the remaining LED digital tubes to the upper surface of the second set of circuit boards.

[0020] Step B: Connect the mounting holes around the two sets of circuit boards to the upper surface of the connecting column through the limiting columns, so that the LED digital tubes and the display slots fit together;

[0021] Step C: Place one side of the lamp housing directly above the back of the light board, aligning the slots on both sides of the lamp housing with the plugs on both sides of the light board. Then, move the lamp housing downward until the screw in the middle of the lamp housing is inserted into the inner screw barrel. Then, use a screwdriver to rotate the rotation groove on the upper surface of the screw.

[0022] Step D: The screw rotates downward in the inner barrel, causing the lamp housing to continuously move downward;

[0023] Step E: As the screw moves downward in the inner barrel, it drives the moving gear to rotate. The moving gear, through meshing with the slave gear, drives the externally threaded rods on both sides of the slave gear to rotate. The externally threaded rods and the inner barrel cooperate with each other to drive the positioning blocks to move in opposite directions in the channel.

[0024] Step F: When the lamp housing moves downward and the plug-in board is inserted into the slot, the positioning block moves out through the notch on one side of the channel and is inserted into the positioning slot of the plug-in board, thus completing the fixation between the lamp housing and the lamp board;

[0025] Step G: When the lamp housing moves downward, the lamp housing connection limiting cylinder moves downward until the plug-in board is inserted into the slot. The limiting cylinder fits on one side of the circuit board, fixing the circuit board between the receiving column and the limiting cylinder, thus completing the fixation of the circuit board.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The double connection assembly provided by the present invention uses a positioning block and an inner screw barrel to connect the middle of the lamp housing to the lamp board through the inner screw barrel, and the two sides of the lamp housing are double-connected to the two sides of the lamp board, thereby achieving a stable fixation between the lamp housing and the lamp board. Compared with the traditional screw connection method, the connection is more convenient and quick, and a stable fixation effect can be achieved without fixing all four sides.

[0028] The receiving column, limiting column and limiting cylinder provided at the same time can further fix the circuit board between the lamp housing and the lamp board, preventing the circuit board from vibrating during use and improving the connection stability of multiple groups of LED digital tubes;

[0029] A rubber pad is set between the lamp housing and the lamp board. Through the rotational extrusion between the inner screw barrel and the screw, the rubber pad will undergo a certain deformation, filling the gap between the lamp housing and the lamp board. At the same time, it provides a certain elastic deformation to ensure a stable connection between the two and also increases the downward stroke of the screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Furthermore, a channel 202 for the positioning block 209 to slide is defined inside the lamp housing 2 , and a notch 210 is defined on one side of the channel 202 so that the positioning block 209 can be moved out of the channel 202 through the notch 210 .

[0045] Furthermore, a rotation groove 2031 is formed on the upper surface of the screw rod 203 , so that a screwdriver can be connected to the screw rod 203 through the rotation groove 2031 and rotated.

[0046] Furthermore, a matching screw barrel 4 is provided on the inner side of the lamp panel 1 , and the matching screw barrel 4 and the screw rod 203 cooperate with each other.

[0051] A method for assembling an array-type digital tube includes the following steps:

[0052] Step A: Solder one set of LED digital tubes 3 to the upper surface of the circuit board 5, and then solder the remaining LED digital tubes 3 to the upper surface of the second set of circuit boards 5;

[0053] Step B: Connect the mounting holes around the two sets of circuit boards 5 to the upper surface of the connecting column through the limiting columns 1041, so that the LED digital tubes 3 and the display slots 102 fit together;

Then, move the lamp housing 2 downward until the screw 203 in the middle of the lamp housing 2 is inserted into the inner screw barrel 208.

[0057] Step F: When the lamp housing 2 moves downward and the plug-in board 103 is inserted into the slot 201, the positioning block 209 moves out through the notch 210 on one side of the channel 202 and is inserted into the positioning groove 1031 of the plug-in board 103, thereby completing the fixation between the lamp housing 2 and the lamp board 1;

[0058] Step G: When the lamp housing 2 moves downward, the lamp housing 2 connected to the limiting cylinder 204 moves downward until the plug-in board 103 is inserted into the slot 201. The limiting cylinder 204 fits on one side of the circuit board 5, fixing the circuit board 5 between the receiving column 104 and the limiting cylinder 204, completing the fixation of the circuit board 5.

[0059] The array-type digital tube and the assembly method thereof of the present invention have the following advantages:

[0060] The double connection assembly provided in the present invention uses the positioning block 209 and the inner screw barrel 208 to connect the middle of the lamp housing 2 to the lamp board 1 through the inner screw barrel 208, and the two sides of the lamp housing 2 are double-connected to the two sides of the lamp board 1, thereby achieving stable fixation between the lamp housing 2 and the lamp board 1. Compared with the traditional screw connection method, the connection is more convenient and quick, and a relatively stable fixing effect can be achieved without fixing all four sides.

[0061] The receiving column 104, the limiting column 1041 and the limiting cylinder 204 provided at the same time can further fix the circuit board 5 between the lamp housing 2 and the lamp board 1, thereby preventing the circuit board 5 from vibrating during use and improving the connection stability of the multiple groups of LED digital tubes 3;

[0062] A rubber pad is arranged between the lamp housing 2 and the lamp board 1. Through the rotational extrusion between the inner screw barrel 208 and the screw 203, the rubber pad will undergo a certain deformation, filling the gap between the lamp housing 2 and the lamp board 1, while providing a certain elastic deformation to ensure a stable connection between the two, and also increasing the downward stroke of the screw 203.
