Description

Technical Field

[0001] The present invention relates to the technical field of display cabinets, and in particular to an adjustable lamp used in display cabinets. Background Art

[0002] In the display industry, display cabinets are the main display carriers for commodities, artworks, cultural relics and other items. Their internal lighting effects are crucial to improving the display effect, attracting the audience's attention and protecting the displayed items. Traditional display cabinet lamps often adopt a fixed design and cannot be flexibly adjusted according to the characteristics of the displayed items or the display requirements, resulting in a single lighting effect and difficulty in meeting the diverse display needs. In order to solve this problem, in recent years, adjustable lamp technology has been gradually applied to display cabinets. This type of lamp uses advanced mechanical structure and electronic control technology to achieve precise adjustment of lighting angle, brightness and color temperature. Users can flexibly adjust the lighting parameters of the lamp according to factors such as the shape, material, color and display environment of the displayed items to achieve the best display effect. In the current use of display cabinets, in order to improve the display effect of exhibits, soft light paper is usually installed in front of the lighting fixture. This practice uses the characteristics of soft light paper to soften the light and reduce glare, so that the exhibits appear softer and more natural when displayed. In addition, staff can further enhance the softening effect of light by increasing the number of soft light paper layers. However, when multiple layers of soft paper are used at the same time, the soft paper near the lighting fixture is usually more worn out than the soft paper at other locations due to the direct light exposure and temperature. Therefore, the staff needs to regularly check and replace the top layer of soft paper, which increases the staff's workload to a certain extent. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and to propose an adjustable lamp used in a display cabinet.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an adjustable lamp used in a display cabinet, comprising a base, a double-layer protective glass is fixedly installed on the top of the base, a cylinder is fixedly installed on the top of the double-layer protective glass, an LED lamp is fixedly installed on the top of the inner cavity of the cylinder, a sinking cavity and a flip cavity are arranged inside the cylinder, and two electric push rods are fixedly installed on the bottom of the inner cavity of the cylinder, and the top telescopic ends of the two electric push rods are fixedly installed with cross plates, the bottoms of the two cross plates are welded with outer limit rings and inner limit rings, motors are fixedly installed on the inner side walls of the two outer limit rings, and discs are fixedly installed on the output ends of the two motors, an installation frame 1 is welded between the two discs, a soft light paper 1 is arranged on the inner side of the installation frame 1, and two symmetrical installation grooves 1 are opened on the upper and lower sides of the two discs, a sliding rod 1 is welded on the inner side wall of each of the installation grooves 1, and each of the sliding rods is slidably arranged on the outer peripheral wall A limit rod, a spring 1 is wound around the outer peripheral wall of each sliding rod 1, and each spring 1 is respectively located between the corresponding limit rod and the corresponding mounting groove 1 cavity wall, a vertical plate is welded on the outer side wall of each two limit rods, a semicircular plate is welded on the side wall of each vertical plate, a mounting frame 2 is welded between the side walls of each two semicircular plates, and soft light paper 2 is arranged on the inner side of the two mounting frames 2. The electric push rod drives the soft light paper 1 and the soft light paper 2 to move up, so that the soft light paper 1 and the soft light paper 2 are moved out of the sinking cavity and moved to the center position inside the flip cavity. Then the motor drives the disc, the mounting frame 1 and the soft light paper 1 to flip 180 degrees, and the disc drives the sliding rod 1, the limit rod, the vertical plate, the semicircular plate, the mounting frame 2 and the soft light paper 2 to flip 180 degrees. The soft light paper 1 and the soft light paper 2 are flipped synchronously, so that the soft light paper 2 on the upper and lower sides are swapped, thereby reducing the loss of the soft light paper 2 on one side, thereby improving the service life of the whole set of soft light paper.

[0005] In the above-mentioned adjustable lamp used in display cabinets, a plurality of air bins are fixedly installed at the bottom of the inner cavity of the cylinder, each of the air bins is connected with an air inlet pipeline 1 and an air inlet pipeline 2 at the top, and each of the air bins is connected with an air outlet pipeline 1 and an air outlet pipeline 2 at the bottom, and each of the air bins is slidably provided with a sliding rod 2 on the side wall of each air bin, and a sliding block is welded between each two sliding rods 2 located on one side of the outside of the air bin, and a spring 2 is wound around the outer peripheral wall of each sliding rod 2, and each spring 2 is respectively located between the corresponding sliding block and the corresponding air bin side wall, and a piston plate is welded between each two sliding rods 2 located on one side of the inner cavity of the air bin, and when the electric push rod drives the soft light paper 1 and the soft light paper 2 to move to the center position inside the flip cavity, a setting The slider enters the gap between the outer limit ring and the inner limit ring. When the motor drives the limit rod to flip, the limit rod will push the slider to move in the direction of the gas chamber. The slider drives the piston plate to move through the slide rod 2. The piston plate squeezes the space on the right side, so that the gas inside the space on the right side of the piston plate enters the inner cavity of the cylinder through the air outlet pipe 1. Then the air flow flows upward and passes over the soft light paper 1, the soft light paper 2 and the LED lamp in turn. Finally, the gas is discharged from the inner cavity of the cylinder through the air outlet pipe 3. In this process, the flowing gas will entrain the heat of the soft light paper 1, the soft light paper 2 and the LED lamp to discharge, thereby realizing the heat dissipation of the soft light paper 1 and the soft light paper 2 and the secondary heat dissipation of the LED lamp.

[0006] In the above-mentioned adjustable lamp used in the display cabinet, two air outlet pipes three are connected to the top of the cylinder, and the air inlet ends of the two air outlet pipes three extend to the left and right sides of the LED lamp respectively. During the upward movement of the soft light paper one and the soft light paper two, the air on the top can only be discharged from the inner cavity of the cylinder through the air outlet pipe three. Since the air inlet end of the air outlet pipe three extends to the side of the LED lamp, the air will take away part of the heat emitted by the LED lamp when it is discharged, thereby performing preliminary heat dissipation on the LED lamp.

[0007] In the above-mentioned adjustable lamp applied to the display cabinet, a one-way ventilation valve is arranged in the inner cavity of each of the air inlet pipeline 1, the air inlet pipeline 2, the air outlet pipeline 1, the air outlet pipeline 2 and the air outlet pipeline 3.

[0008] In the above-mentioned adjustable lamp used in the display cabinet, telescopic rods are fixedly installed on the groove bodies on both sides of the sinking cavity, semi-ring plates are fixedly installed on the telescopic ends of the top of the two telescopic rods, and springs three are wound around the outer peripheral walls of the two telescopic rods. In the process of the electric push rod driving the soft light paper one and the soft light paper two to move out of the sinking cavity, the semi-ring plates are tightly abutted against the bottom of the outer limit ring and the inner limit ring under the action of the elastic force of the spring three, and the gap between the outer limit ring and the inner limit ring is sealed with the help of the semi-ring plates.

[0009] In the above-mentioned adjustable lamp used in a display cabinet, a plurality of mounting holes are provided on the peripheral wall of the cylinder.

[0010] In the above-mentioned adjustable lamp used in a display cabinet, a sliding slot hole is provided on the outer peripheral wall of each of the limit rods, and each sliding rod is slidably disposed inside the corresponding sliding slot hole.

[0011] Compared with the existing technology, the advantages of the adjustable lamp used in the display cabinet are:

[0012] 1. At regular intervals, the soft light paper 1 and the soft light paper 2 are turned over synchronously, so that the soft light paper 2 on the upper and lower sides are swapped, thereby reducing the loss of the soft light paper 2 on one side, thereby increasing the service life of the entire set of soft light paper;

[0013] 2. When the soft light paper 1 and the soft light paper 2 are moving upward, the air on the top can only be discharged from the inner cavity of the cylinder through the air outlet pipe 3. Since the air inlet end of the air outlet pipe 3 extends to the side of the LED lamp, the air will take away part of the heat emitted by the LED lamp when it is discharged, so as to perform preliminary heat dissipation on the LED lamp;

[0014] 3. The airflow flows upward and passes through the soft light paper 1, soft light paper 2 and LED lamps in turn. The flowing gas will carry away the heat of the soft light paper 1, soft light paper 2 and LED lamps, so as to achieve the heat dissipation of the soft light paper 1 and soft light paper 2 and the secondary heat dissipation of the LED lamps; in addition, the two soft light papers 2 are gradually separated from the soft light paper 1, so that the flowing gas can more easily take away the heat on the surface of the soft light paper 2 and the soft light paper 1, thereby achieving a better heat dissipation effect;

[0015] 4. The piston plate is gradually reset under the elastic force of spring 2. During this process, the piston plate squeezes the space on its left side, so that the gas in the space on its left side enters the inner cavity of the cylinder, thereby realizing the heat dissipation of soft light paper 1, soft light paper 2 and LED lamps again.

[0031] Furthermore, a plurality of gas bins 23 are fixedly installed at the bottom of the inner cavity of the cylinder 3, and each gas bin 23 is connected with an air inlet pipeline 1 24 and an air inlet pipeline 2 25 at the top, and an air outlet pipeline 1 26 and an air outlet pipeline 2 27 at the bottom of each gas bin 23. A sliding rod 28 is slidably arranged on the side wall of each gas bin 23, and a slider 29 is welded between each two sliding rods 28 on one side outside the gas bin 23, and a spring 2 30 is wound around the outer peripheral wall of each sliding rod 28, and each spring 2 30 is respectively located between the corresponding slider 29 and the corresponding side wall of the gas bin 23, and a piston plate 31 is welded between each two sliding rods 28 on one side of the inner cavity of the gas bin 23, and telescopic rods 34 are fixedly installed in the groove bodies on both sides of the sinking cavity 5, and semi-ring plates 35 are fixedly installed at the top telescopic ends of the two telescopic rods 34. A spring three 36 is provided, and two air outlet pipes three 32 are connected to the top of the cylinder 3, and the air inlet ends of the two air outlet pipes three 32 extend to the left and right sides of the LED lamp 4 respectively. In the process of the electric push rod 7 driving the soft light paper one 14 and the soft light paper two 22 to move out of the sinking cavity 5, the semi-annular plate 35 is tightly abutted against the bottom of the outer limit ring 9 and the inner limit ring 10 under the action of the elastic force of the spring three 36. The gap between the outer limit ring 9 and the inner limit ring 10 is sealed with the help of the semi-annular plate 35, so that the air on the top of the soft light paper one 14 and the soft light paper two 22 can only be discharged from the inner cavity of the cylinder 3 through the air outlet pipe three 32 during the upward movement. Since the air inlet end of the air outlet pipe three 32 extends to the side of the LED lamp 4, the air will take away part of the heat emitted by the LED lamp 4 when it is discharged, so as to perform preliminary heat dissipation on the LED lamp 4.

[0032] Furthermore, a plurality of mounting holes 37 are provided on the outer peripheral wall of the cylinder 3, and a one-way vent valve 33 is provided in the inner cavity of each of the air inlet pipeline 1 24, the air inlet pipeline 25, the air outlet pipeline 1 26, the air outlet pipeline 27 and the air outlet pipeline 3 32. The air inlet pipeline 1 24 and the air inlet pipeline 2 25 are respectively installed in the corresponding mounting holes 37, and the one-way vent valve 33 in the air inlet pipeline 1 24 only allows external gas to enter the space on the right side of the piston plate 31, and the one-way vent valve 33 in the air inlet pipeline 2 24 only allows external gas to enter the space on the right side of the piston plate 31.

[0033] Working principle: When in use, the light emitted by the LED lamp 4 passes through the soft light paper 1 14 and the soft light paper 2 22 to illuminate the exhibits inside the double-layer protective glass 2. The soft light paper 1 14 and the soft light paper 2 22 can soften the light and reduce glare, making the exhibits softer and more natural when displayed; at regular intervals, the electric push rod 7 drives the soft light paper 1 14 and the soft light paper 2 22 to move up, so that the soft light paper 1 14 and the soft light paper 2 22 are moved out of the sinking cavity 5 and moved into the flip cavity 6 The first part is centered, and then the motor 11 is set to drive the disc 12, the installation frame 13 and the soft light paper 14 to turn 180 degrees. The disc 12 drives the sliding rod 16, the limit rod 17, the vertical plate 19, the semicircular plate 20, the installation frame 21 and the soft light paper 22 to turn 180 degrees. The soft light paper 14 and the soft light paper 22 are turned synchronously, so that the soft light paper 22 on the upper and lower sides is exchanged, thereby reducing the loss of the soft light paper 22 on one side, so as to improve the service life of the whole set of soft light paper;

[0034] In the process of the electric push rod 7 driving the soft light paper 14 and the soft light paper 22 to move out of the sinking cavity 5, the semi-ring plate 35 is tightly abutted against the bottom of the outer limit ring 9 and the inner limit ring 10 under the action of the elastic force of the spring 36, and the gap between the outer limit ring 9 and the inner limit ring 10 is sealed by means of the semi-ring plate 35, so that the soft light paper 14 and the soft light paper 22 can only be discharged from the inner cavity of the cylinder 3 through the air outlet pipe 3 32 during the upward movement. Since the air inlet end of the air outlet pipe 3 32 extends to the side of the LED lamp 4, the air will take away part of the heat emitted by the LED lamp 4 when it is discharged, so as to perform preliminary heat dissipation on the LED lamp 4; it should be noted that the air outlet pipe 3 32 can be connected to the external pipeline, which is convenient for discharging the hot air inside the cylinder 3;

[0035] When the soft light paper 14 and the soft light paper 22 move to the central position inside the flip chamber 6 and the motor 11 drives the soft light paper 14 and the soft light paper 22 to flip, since there are two grooves on the inner ring surface of the outer limit ring 9 and the inner limit ring 10, in the process of flipping to nearly 90 degrees, the set limit rod 17 is displaced into the grooves of the outer limit ring 9 and the inner limit ring 10 under the action of the elastic force of the spring 18. At this time, the set limit rod 17 drives the vertical plate 19, the semicircular plate 20, the installation frame 21 and the soft light paper 22 to move away from the soft light paper 14, so that the two soft light papers 22 are gradually separated from the soft light paper 14; it should be noted that the position of the set soft light paper 14 remains unchanged, and the two symmetrically set soft light papers 22 gradually move away from the soft light paper 14. When flipped to 90 degrees, the two symmetrically set soft light papers 22 move to the farthest distance from the soft light paper 14;

[0036] When the electric push rod 7 drives the soft light paper 14 and the soft light paper 22 to move to the center position inside the flip chamber 6, the set slider 29 enters the gap between the outer limit ring 9 and the inner limit ring 10. When the motor 11 drives the limit rod 17 to flip, the limit rod 17 will push the slider 29 to move in the direction of the gas warehouse 23. The set slider 29 drives the piston plate 31 to move through the slide rod 28. The set piston plate 31 squeezes the space on the right side of the piston plate 31, so that the gas inside the space on the right side of the piston plate 31 enters the inner cavity of the cylinder 3 through the air outlet pipe 1 26. Then the air flow flows upward and passes through the soft light paper 1 14, the soft light paper 22 and the LED lamp 4 in turn. Finally, the gas is discharged from the inner cavity of the cylinder 3 through the air outlet pipe 3 32. In this process, the flowing gas will entrain the heat of the soft light paper 1 14, the soft light paper 22 and the LED lamp 4 to discharge, so as to achieve the heat dissipation of the soft light paper 1 14 and the soft light paper 22 Heat and secondary heat dissipation of the LED lamp 4; in addition, the two soft light papers 22 are gradually separated from the soft light paper 1 14, so that the flowing gas can more easily take away the heat on the surface of the soft light paper 22 and the soft light paper 1 14, thereby making the heat dissipation effect better; when the motor 11 drives the soft light paper 1 14 and the soft light paper 22 to flip from 90 degrees to 180 degrees, the limit rod 17 drives the soft light paper 2 22 to gradually reset; the piston plate 31 is gradually reset under the elastic force of the spring 2 30. During this process, the piston plate 31 will squeeze the space on its left side, so that the gas in the space on its left side enters the inner cavity of the cylinder 3, thereby realizing the secondary heat dissipation of the soft light paper 1 14, the soft light paper 22 and the LED lamp 4; it should be noted that the air intake pipe 1 24 and the air intake pipe 2 25 can be connected to the external pipeline, which is convenient for sucking in the cold air outside the cylinder 3 to participate in the heat dissipation operation.

[0037] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
