Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a magnetic attraction lighting lamp. Background Art

[0002] In the field of lighting, the installation and replacement of lamps has always been an important technical link, especially when working in high-altitude environments, safety issues are particularly prominent. Traditional screw-connected lamps are fixed by closely fitting the threads with the lamp holder. However, when such lamps are located at high altitudes, the replacement process often requires operators to climb up to operate, which not only increases the difficulty of the operation, but also significantly increases the safety risks. High-altitude operations not only require operators to have superb skills and rich experience, but also face complex working environments and potential dangerous factors, such as falling from heights and electric shocks.

[0003] In order to overcome the difficulty of high-altitude replacement of traditional screw-type lamps, an innovative product, magnetic lamps, has appeared on the market in recent years. Magnetic lamps use built-in magnets to directly attach the bulb to the lamp holder, making it easy to install and remove without tools. This design greatly simplifies the replacement process of lamps, reduces the skill requirements for operators, and also reduces the time of high-altitude operations to a certain extent, improving work efficiency.

[0004] However, despite the significant advantages of magnetic lamps in terms of convenience, they still have defects that cannot be ignored in practical applications. Specifically, since magnetic lamps lack an effective locking mechanism, they only rely on the adsorption force of the magnet to maintain the connection between the bulb and the lamp holder, which increases the risk of the lamp falling to a certain extent. Especially in harsh environmental conditions such as strong winds and frequent vibrations, the adsorption force of the magnet may be seriously affected, causing the lamp to accidentally fall off, which in turn causes safety accidents.

[0005] In addition, long-term use of magnetic lamps may also face the problem of magnet performance degradation. As the use time increases, the magnet may weaken its adsorption force due to changes in magnetization direction and magnetic domain structure, further increasing the risk of the lamp falling.

[0006] In summary, although the magnetic lamps in the prior art have solved the problem of replacing lamps at high altitudes to a certain extent, the risks of falling and the degradation of magnet performance still need to be solved. Therefore, it is necessary to further optimize and improve the structure and performance of magnetic lamps to improve their safety and reliability while facilitating installation and disassembly.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] like Figure 1 to Figure 5 As shown, embodiment 1, a magnetic lighting lamp, includes a lamp holder 1 and a bulb 2; a slot 11 for plugging the bulb 2 is provided on the lamp holder 1, a contact plate 12 is movably provided in the slot 11, and the contact plate 12 is elastically connected to the top wall of the slot 11 by a first return spring 13; the contact plate 12 is electrically connected to the electrical connection part of the bulb 2, and the contact plate 12 and the electrical connection part of the bulb 2 are also magnetically connected, and the bulb 2 is detachably connected to the slot 11 by a snap-fit ​​mechanism that is unlocked by pressing.

[0028] When the bulb 2 is plugged into the lamp holder 1, the bulb 2 and the lamp holder 1 are magnetically fixed, and the bulb 2 is locked by a snap-fit ​​mechanism to prevent the bulb 2 from accidentally falling off due to uncontrollable external forces, such as accidental collision with objects blown by the wind or accidental collision with birds. When taking out the bulb 2, it is only necessary to press the bulb 2 to pull it out, which not only solves the difficulty of installing the bulb 2 by threading at high altitude, reduces the risk of high-altitude operations, but also avoids the risk of the bulb 2 accidentally falling off.

[0029] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0030] The snap-fitting mechanism is two groups of spring pins 14, which are symmetrically arranged on the inner wall of the slot 11. The pin heads 141 of the spring pins 14 extend into or retract out of the slot 11, and the pin heads 141 of the spring pins 14 are provided with a downwardly inclined guiding slope 142; the top fixed sleeve of the electrical connection part of the bulb 2 is provided with a first annular cone 21, and the middle movable sleeve of the electrical connection part of the bulb 2 is provided with a second annular cone 22, and the maximum diameter surface of the second annular cone 22 faces the maximum diameter surface of the first annular cone 21.

[0031] When the electrical connection part of the bulb 2 is inserted into the slot 11, the first annular cone 21 pushes the pin head 141 of the spring pin 14 out of the slot 11, and the electrical connection part of the bulb 2 can be smoothly inserted into the slot 11. When the pin head 141 of the spring pin 14 falls off the first annular cone 21, the pin head 141 of the spring pin 14 extends out again and is inserted between the first annular cone 21 and the second annular cone 22, thereby achieving locking and preventing the bulb 2 from accidentally falling off due to external force.

[0032] When the light bulb 2 needs to be replaced, it is only necessary to press the light bulb 2. At this time, the first reset spring 13 is compressed, and the contact plate 12 moves upward. At the same time, the guide bevel 142 conflicts with the edge of the maximum diameter surface of the second annular cone 22, and the pin head 141 of the spring pin 14 retracts. When the guide bevel 142 is separated from the edge of the maximum diameter surface of the second annular cone 22, the pin head 141 of the spring pin 14 is reset and conflicts with the peripheral wall of the second annular cone 22. At this time, the light bulb 2 is pulled out, and the pin head 141 of the spring pin 14 drives the second annular cone 22 to move upward until it conflicts with the first annular cone 21. Subsequently, the pin head 141 of the spring pin 14 transitions from the peripheral wall of the second annular cone 22 to the peripheral wall of the first annular cone 21, thereby realizing the removal of the light bulb 2.

[0033] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 2, and its details are as follows:

[0034] The electrical connection part of the bulb 2 is also sleeved with a second reset spring 23, one end of the second reset spring 23 is fixedly connected to the bottom of the second annular cone 22, and the other end is fixedly connected to the electrical connection part of the bulb 2. The second reset spring 23 is provided so that there is always a gap between the first annular cone 21 and the second annular cone 22 before the bulb 2 is installed and after the bulb 2 is pulled out, so that the pin head 141 of the spring pin 14 can enter the gap between the first annular cone 21 and the second annular cone 22 to achieve a buckle when the bulb 2 is installed; such a setting can avoid the situation where the second annular cone 22 cannot automatically reset under the action of gravity when the lamp holder 1 is installed sideways, forwardly or at other angles.

[0035] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 3, and its details are as follows:

[0036] The diameter of the maximum diameter surface of the second annular cone 22 is larger than that of the maximum diameter surface of the first annular cone 21. When the bulb 2 is pulled out, the pin head 141 of the spring pin 14 can more smoothly transition from the peripheral wall of the second annular cone 22 to the peripheral wall of the first annular cone 21.

[0037] Embodiment 5: This embodiment is a further improvement based on any one of Embodiments 1 to 4, and its details are as follows:

[0038] The upper end surface of the electrical connection part of the bulb 2 is provided with a first magnetic ring 25 and two spring probes 24 electrically connected to the positive and negative poles of the bulb 2 in sequence from the outside to the inside; the lower end surface of the contact plate 12 is provided with a second magnetic ring 121, a metal ring 122 and a metal sheet 123 in sequence from the outside to the inside; the first magnetic ring 25 matches the second magnetic ring 121 in position and has opposite polarities; the metal ring 122 and the metal sheet 123 are electrically connected to the positive and negative poles of the power line respectively, and the two spring probes 24 are electrically connected to the metal ring 122 and the metal sheet 123 respectively.

[0039] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0040] A guide arc surface 111 is provided at the insertion opening of the slot 11. Under the guidance of the guide arc surface 111, the bulb 2 is more easily inserted into the slot 11.

[0041] Embodiment 7, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0042] A limit stop ring 112 is provided in the slot 11, and the contact plate 12 is provided between the limit stop ring 112 and the inner top wall of the slot 11. The limit stop ring 112 can block the contact plate 12 to prevent the contact plate 12 from being pulled out due to the magnetic effect of the magnet, or the spring from being overstretched and damaged.

[0043] Embodiment 8: This embodiment is a further improvement on the basis of Embodiment 1, and its details are as follows:

[0044] A power line groove 15 is provided at the bottom of the lamp holder 1. The power line of the lamp holder 1 can be hidden in the power line groove 15, and the power line can be well protected when the lamp holder 1 is installed, and the power line will not be compressed or damaged.

[0045] Embodiment 9: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0046] The lamp holder 1 is provided with a plurality of mounting nail holes 16 so as to be able to install and fix the lamp holder 1 by bolts or expansion screws.
