Description

Technical Field

[0001] The invention relates to the technical field of lighting table lamps, and in particular to an energy-saving table lamp with an automatic directional lampshade based on a connecting rod structure. Background Art

[0002] A desk lamp is a household item used for lighting. It is usually placed on a desk, bedside, or living room to provide local lighting solutions. There are many types of desk lamps, including floor lamps, table lamps, wall lamps, etc. Different styles and functions meet the different needs of consumers. When using a desk lamp, there will be a long power cord between the external power cord and the wall socket. During use, it is more dangerous and easy to fall off when hit by an external impact, which is less safe.

[0003] For example, a dimmable smart LED lamp provided by authorization announcement number CN115199964B has a winding roller arranged in the base of the smart LED lamp, and an external power cord is wound on the winding roller, and a winding knob is connected to the top of the winding roller. When the smart LED lamp is plugged in and used through the external power cord, the winding roller can be rotated by the winding knob to reel in the external power cord without laying the external power cord on the ground and the bedside table, which can prevent children from tripping over the randomly laid power cord; and when decorating and wiring the bedroom, the height of the wall socket at the head of the bed is generally slightly higher than the height of the bedside table, so that the LED lamp can be placed close to the wall on the bedside table below the wall socket, so that the external power cord outlet on the rear side of the base is directly opposite to the wall socket, the distance between the LED lamp and the socket is minimized as much as possible, and the plug and the socket are further shielded by the LED lamp base, so that the power cord is completely retracted and hidden, further reducing the risk of electric shock caused by children pulling and playing with the power cord. A holder that can be snap-connected and fixed with the protective cover is provided on the back of the LED lamp base. After the protective cover can be operated to be installed on the wall socket to protect the connection point, the holder can be snap-connected to the protective cover and the power cord can be reeled in during the process of the protective cover being snapped on the holder, so that the operation of the protective cover is more convenient and is not easily hindered by the LED lamp base when operating the protective cover. The power cord can be completely retracted and hidden while the connection point can be protected by the protective cover to reduce the risk of electric shock. The base is auxiliary fixed by the cooperation of the protective cover and the base is placed on the bedside table through the support of telescopic legs, thereby improving the stability of the LED lamp placed on the bedside table and preventing the LED lamp from being accidentally touched, dropped and damaged.

[0004] It has major disadvantages: during the installation of the device, the connector will clash with the socket, and a large force is used to press the base close to the wall socket to retract the connector. During the continuous squeezing process, the connector gradually approaches the pin hole, causing the connector to enter the pin hole, with poor efficiency. At the same time, the connector and the pin hole are directly inserted, and when the base encounters a large pulling force, the connector will fall out of the pin hole, resulting in poor fixing effect. Summary of the invention

[0005] The embodiment of the present application provides an energy-saving desk lamp with an automatic directional lampshade based on a connecting rod structure, thereby solving the problem in the prior art that during the installation process of the device, the connecting head will conflict with the socket. The base needs to be pressed close to the wall socket with a large force to retract the connecting head. During the continuous squeezing process, the connecting head gradually approaches the pin hole, so that the connecting head enters the pin hole, which has poor efficiency. At the same time, the connecting head and the pin hole are directly inserted. When the base encounters a large pulling force, the connecting head will fall out of the pin hole, and the fixing effect is poor. The second telescopic rod, the limiting cylinder and the limiting hole are tilted. After the fixed seat is subjected to force, the tilted limiting cylinder can provide a pulling force in the opposite direction to the fixed cover, thereby improving the fixing effect. The limiting cylinder is controlled to retract by an electromagnet. During the installation process, the limiting cylinder does not conflict with the side of the fixed cover away from the fixed seat, thereby improving the installation efficiency.

[0063] As an improvement, the second wire hole is located at the inner top corner of the sliding cylinder.

[0064] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0065] First, the telescopic rod, the limiting cylinder and the limiting hole are arranged at an inclination. After the fixing seat is subjected to force, the inclined limiting cylinder can provide a pulling force in the opposite direction to the fixing cover, thereby improving the fixing effect. In addition, the limiting cylinder is controlled to be extended and retracted by the electromagnet. During the installation process, the limiting cylinder does not interfere with the side of the fixing cover away from the fixing seat, thereby improving the installation efficiency.

[0066] Secondly, the limiting cylinder and the limiting hole are fixed to each other through the cooperation between the spiral slideway and the spiral protrusion, which can improve the connection effect between the two. The rotation of the spiral can generate greater friction, thereby increasing the stability of the connection. Compared with the simple straight-insertion pin connection, this connection method is more difficult to be accidentally pulled out, thereby improving the overall structural stability of the equipment; and when the limiting cylinder and the limiting hole are fixed to each other through the spiral slideway and the spiral protrusion, the impact force of the limiting cylinder inserted into the limiting hole can be reduced, which helps to protect the limiting cylinder and the limiting hole, and the damage that may be caused by the sudden impact between the spiral slideway and the spiral protrusion, thereby extending the service life of the equipment; the wear resistance is enhanced, and the contact area of ​​the spiral structure is larger than that of the straight-insertion type, which means that under the same pressure, the pressure per unit area will be reduced, thereby reducing wear;

[0067] Thirdly, the expansion of the expansion membrane fits the inner wall of the limiting hole and the spiral protrusion. This all-round contact greatly increases the friction between the limiting cylinder and the limiting hole, thereby significantly improving the stability of the fixation. Even when subjected to external force, it is more difficult for the connector to come out of the pin hole. In addition, the expansion membrane is sleeved on the outside of the limiting cylinder to reduce the wear of the limiting cylinder and increase the service life of the device. The adjustable fixing force can accurately adjust the fixing force between the limiting cylinder and the limiting hole by controlling the inflation amount of the expansion membrane. This adjustability enables the design to adapt to limiting holes of different sizes and materials, as well as the fixing requirements in different application scenarios.

[0068] Fourthly, it can further improve the fixing stability. By adsorbing the magnetic material at one end of the limit cylinder by the second electromagnet, a closer contact surface can be formed, thereby increasing the friction between the limit cylinder and the limit hole. This increased friction helps to resist external forces, improve the stability of the connection, and prevent the limit cylinder from loosening during long-term use; and the limit cylinder is continuously adsorbed by the second electromagnet, which can continuously improve the fixing effect.

[0130] During use, the user adjusts the height by adjusting the rotation of the foot 140 to adapt to the height of the wall socket. First, the power cord 160 is pulled out and plugged into the wall socket. The device is first connected to the power supply, and the electromagnet 1 260 is energized through the control screen 170.

In addition, the limiting cylinder 320 is controlled to be extended and retracted by the electromagnet 260. During the installation process, the limiting cylinder 320 does not interfere with the side of the fixing cover 210 away from the fixing seat 110, thereby improving the installation efficiency.

[0132] Embodiment 2: When the embodiment 1 is in use, the fixing effect is improved by the inclined telescopic rod 210, the limiting cylinder 320 and the limiting hole 211. However, when in use, the fixing effect is poor. When the fixing seat 110 encounters a large force, it is still possible to detach from the limiting hole 211; at the same time, when the limiting cylinder 320 enters the limiting hole 211, the telescopic rod 210 has a large impact force, which will cause the limiting cylinder 320 and the limiting hole 211 to be damaged, and the service life is reduced. Based on this, the solution of the embodiment 1 is improved, such as Figure 14-15 As shown:

[0133] The clamping assembly 200 further includes a spiral protrusion 212;

[0134] The limiting hole 211 is provided with a spiral protrusion 212. In the initial state, the spiral line of the spiral protrusion 212 and the axis of the limiting cylinder 320 are on the same straight line;

[0135] The limiting cylinder 320 is rotatably connected to the telescopic rod 2 310, and the rotation axis of the limiting cylinder 320 and the axis of the limiting cylinder 320 are on the same straight line;

[0136] The limiting assembly 300 further includes a spiral slide 321;

[0137] The outer wall of the limiting cylinder 320 is provided with a spiral slideway 321 which cooperates with the spiral protrusion 212, and the axis of the spiral slideway 321 is on the same straight line as the axis of the limiting cylinder 320;

[0138] When the limiting cylinder 320 enters the limiting hole 211 , the spiral protrusion 212 cooperates with the spiral slideway 321 . As the limiting cylinder 320 continuously extends into the limiting hole 211 , the limiting cylinder 320 continuously rotates.

[0139] When the limiting cylinder 320 extends into the limiting hole 211, the limiting cylinder 320 rotates at one end of the telescopic rod 310, and the limiting cylinder 320 rotates into the limiting hole 211, and the spiral slide 321 and the spiral protrusion 212 cooperate with each other to fix the position of the limiting cylinder 320.

[0140] The limiting cylinder 320 and the limiting hole 211 are fixed to each other through the spiral slide 321 and the spiral protrusion 212, which can improve the connection effect between the two. The rotation of the spiral can generate greater friction, thereby increasing the stability of the connection. Compared with the simple straight-insertion pin connection, this connection method is more difficult to be accidentally pulled out, thereby improving the overall structural stability of the equipment; and when the limiting cylinder 320 and the limiting hole 211 are fixed to each other through the spiral slide 321 and the spiral protrusion 212, the impact force of the limiting cylinder 320 inserted into the limiting hole 211 can be reduced, which helps to protect the limiting cylinder 320 and the limiting hole 211, and the damage that may be caused by sudden impact between the spiral slide 321 and the spiral protrusion 212, thereby extending the service life of the equipment; the wear resistance is enhanced, and the contact area of ​​the spiral structure is larger than that of the straight-insertion type, which means that under the same pressure, the pressure per unit area will be reduced, thereby reducing wear.

[0141] Embodiment 3: During the use of embodiment 2, the fixing effect between the limiting cylinder 320 and the limiting hole 211 is improved by the spiral slide 321 and the spiral protrusion 212, and the wear resistance is enhanced; however, during the use, the fixing effect can be further improved, and after long-term use, the limiting cylinder 320 and the limiting hole 211, the spiral slide 321 and the spiral protrusion 212 are greatly worn, and the limiting cylinder 320 will shake in the limiting hole 211, resulting in poor stability. Based on this, the solution of embodiment 2 is improved, such as Figure 16-17 As shown:

[0142] The limiting assembly 300 further includes an expansion membrane 330 and an inflatable plate 340;

[0143] The expansion membrane 330 wraps the outer wall of the limiting cylinder 320, and the inflation plate 340 is fixed on the expansion membrane 330, and the inflation plate 340 is located at one end of the telescopic rod 310 away from the sliding cylinder 230;

[0144] A sealed expansion space is formed between the expansion membrane 330 and the limiting cylinder 320;

[0145] The inflation plate 340 is provided with an air inlet pipe, and the air inlet pipe is connected with the expansion space, and the air inlet pipe is provided with a valve;

[0146] The air intake pipe input end on the inflation plate 340 can be externally connected to an air intake structure;

[0147] The air intake pipe on the inflation plate 340 is connected to the air intake structure, and the valve is opened to expand or contract the expansion space.

[0148] Before the limiting cylinder 320 is extended into the limiting hole 211, the expansion membrane 330 is completely in contact with the limiting cylinder 320 and the spiral slide 321. After the limiting cylinder 320 is extended into the limiting hole 211, the air intake pipe on the inflation plate 340 is connected to the air intake structure, the valve on the air intake pipe is opened, and the expansion space is inflated to expand the expansion membrane 330. After the expansion, the expansion membrane 330 can completely fit with the limiting hole 211 and the inner wall of the spiral protrusion 212 for fixation, and the expansion membrane 330 located outside the limiting hole 211 can fit with the outer side of the fixed cover 210 after the expansion membrane 330 is inflated; before disassembly is required, the air intake pipe on the inflation plate 340 is connected to the air intake structure, the valve on the air intake pipe is opened, and air is evacuated in the expansion space to make the expansion membrane 330 completely fit with the limiting cylinder 320 and the spiral slide 321, and then it can be disassembled normally.

[0149] Through the expansion of the expansion membrane 330, the friction between the limiting hole 211 and the inner wall of the spiral protrusion 212 is greatly increased, thereby significantly improving the stability of the fixation. Even when subjected to external force, it is more difficult for the connector to come out of the pin hole. The expansion membrane 330 is sleeved on the outside of the limiting tube 320 to reduce the wear of the limiting tube 320 and increase the service life of the device. The adjustable fixing force can accurately adjust the fixing force between the limiting tube 320 and the limiting hole 211 by controlling the inflation amount of the expansion membrane 330. This adjustability enables the design to adapt to limiting holes 211 of different sizes and materials, as well as fixing requirements in different application scenarios.

[0150] Embodiment 4: When the embodiment 3 is in use, the expansion membrane 330 is expanded to improve the fixing effect of the limiting cylinder 320 in the limiting hole 211. However, during the use of the device, the device can be further improved to improve the fixing effect of the limiting cylinder 320 in the limiting hole 211. Based on this, the solution of the embodiment 3 is improved, such as Figure 3 , Figure 18-Figure 20 As shown:

[0151] The support assembly 100 includes a second reel 180. The second reel 180 is provided on a side of the fixing seat 110 close to the fixing cover 210. The second reel 180 is located above the first reel 150, and the second reel 180 has the same structure as the first reel 150.

[0152] The clamping assembly 200 further includes a second wire hole 222, a second electromagnet 270 and a connecting wire 280;

[0153] The sliding plate 220 is provided with a second wire hole 222, and the second wire hole 222 is located in the sliding cylinder 230, and the second wire hole 222 is located at the inner top corner of the sliding cylinder 230;

[0154] The shape of the second electromagnet 270 is consistent with that of the sliding cylinder 230 , and the second electromagnet 270 is fixed to one end of the sliding cylinder 230 away from the sliding plate 220 ;

[0155] The second reel 180 is used to reel in the connecting wire 280. The connecting wire 280 is reeled in the second reel 180. One end of the connecting wire 280 is electrically connected to the control screen 170. The end of the connecting wire 280 away from the electrical connection with the control screen 170 passes through the second wire hole 222 of the fixing seat 110 and is connected to the second electromagnet 270.

[0156] The limiting cylinder 320 is elastic;

[0157] When the electromagnet 270 is energized, it can absorb the magnetic material at one end of the limiting cylinder 320, so that the elastic limiting cylinder 320 is bent.

[0158] During use, after the limiting cylinder 320 extends into the limiting hole 211 and the expansion membrane 330 is fully expanded, the electromagnet 270 is started to absorb the magnetic material at one end of the limiting cylinder 320, causing the limiting cylinder 320 to bend in the direction close to the wall socket, thereby providing a fixing effect.

[0159] The fixing stability can be further improved. By adsorbing the magnetic material at one end of the limiting cylinder 320 by the electromagnet 270, a tighter contact surface can be formed, thereby increasing the friction between the limiting cylinder 320 and the limiting hole 211. The increased friction helps to resist external forces, improve the stability of the connection, and prevent the limiting cylinder 320 from loosening during long-term use. Moreover, the limiting cylinder 320 is continuously adsorbed by the electromagnet 270, which can continuously improve the fixing effect.

[0160] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
