Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a rotating clamping device for lamps. Background Art

[0002] As a highly specialized industrial facility, the operating environment of a nuclear power plant is full of extreme conditions such as radioactivity, high temperature, high humidity and strong electromagnetic interference, which place extremely stringent requirements on lighting equipment. Traditional ordinary lamps are difficult to meet the complex needs of nuclear power plants in terms of light source stability, radiation resistance and safety protection level. Therefore, linear LED lights, as an advanced lighting solution, have gradually taken a dominant position in nuclear environments such as nuclear power plants. This type of LED lamp not only has significant advantages such as high efficiency and energy saving, long life, and adjustable light color, but more importantly, they can be customized for the special environment of nuclear power plants to meet the high standards for protection performance, installation convenience and maintenance efficiency.

[0003] However, with the increasing number of nuclear power plants and the increasing requirements for the standardization of module lamps, existing linear LED lamps still have certain limitations in terms of module splicing and protection performance. The traditional linear lamp splicing method often relies on screw fixation, which is not only cumbersome to disassemble and assemble, increasing maintenance costs, but also prone to loosening during long-term use, affecting the stability and safety of the lamp. In addition, the connection between modules mostly uses electrical connectors. Although this connection method realizes the transmission of electrical signals, it has obvious deficiencies in protection performance. The live parts are exposed to the outside, which is very likely to cause the risk of electric shock in the harsh nuclear environment, seriously threatening the personal safety of the staff. Moreover, this structural module cannot be truly unified, resulting in low integration of the entire lighting system and complex maintenance and management.

[0004] The existing patent CN219177564U discloses a modular lamp that is easy to disassemble and assemble, including a mounting frame, a light-emitting module, a first clamping portion and a second clamping portion, and the mounting frame is provided with a mounting hole; one end of the light-emitting module is installed in the mounting hole through a screw-on structure; one of the first clamping portion and the second clamping portion is arranged on the outer wall of the mounting frame, and the other is arranged on the outer wall of the light-emitting module, and the first clamping portion and the second clamping portion are engaged with each other to limit the rotation of the light-emitting module relative to the mounting frame; wherein the first clamping portion can be moved away from the second clamping portion, and when the first clamping portion is moved away from the second clamping portion, the light-emitting module can be rotated away from the mounting hole.

[0005] The existing patent CN208253256U discloses a bidirectional rotating shaft structure based on modular assembly, including a fixed seat, one side of the fixed seat is provided with a clamping piece, and the two ends of the other side are respectively provided with a fixed round cover and a removable round cover, and the removable round cover is detachably connected to the fixed seat; it also includes a central axis round cover, and the same bolt rod is sleeved on the axis center line of the central axis round cover, the fixed round cover and the removable round cover; a screw seat is movably sleeved in the fixed round cover and the screw seat is assembled on the bolt rod, a nut matching the bolt rod is installed in the removable round cover, and a tail cover is assembled at the end of the removable round cover; a clamping column is provided on the side of the central axis round cover, and a central axis seat is rotatably sleeved on the clamping column; a rotating component for limiting the rotation of the central axis seat is provided between one side of the central axis seat and the central axis round cover, so as to achieve bidirectional adjustment of the rotating shaft.

[0006] In summary, the above two existing patents do not solve the problems in the prior art that the traditional linear lamp splicing method is cumbersome to disassemble and assemble, easily causes the risk of electric shock and has low integration. Summary of the invention

[0035] In order to solve the problems in the prior art of the traditional linear lamp splicing method, which is complicated to disassemble and assemble, easily causes the risk of electric shock and has low integration, the present invention provides a rotating clamping device for lamps.

[0036] To achieve the above purpose, the present invention proposes a rotating clamping device for a lamp. The present invention rotates and installs the lamp by cooperating with the rotating buckle and the side cover. The rotating buckle is inserted into the through hole of the side cover and is installed by components such as a clamping block, a first clamping slot, and a second clamping slot. The present invention not only ensures that two adjacent work platform lamps are firmly spliced, but also facilitates maintenance and replacement.

[0037] See also Figures 1 to 3 As shown, a preferred embodiment of a rotating clamping device for a lamp is specifically illustrated.

[0038] See also Figure 1 As shown, the rotating clip device includes a rotating clip 1 and side covers 2 and sealing rings 3 on both sides thereof. A through hole 4 is provided at one end of the side cover 2 close to the rotating clip 1, and a clamping block 5 is provided on the inner wall of the through hole 4. Two sealing rings 3 are sleeved on the outer walls at both ends of the rotating clip 1. The two ends of the rotating clip 1 are installed in the through holes 4 of the side cover 2. Both ends of the rotating clip 1 can be operably engaged or disengaged with the corresponding clamping block 5.

[0039] As a specific embodiment of the rotating buckle 1, the rotating buckle 1 specifically includes an annular seat 6 and a limiting ring 7 and two arc-shaped limiting plates 8 installed on both sides thereof. The limiting ring 7 is a circular ring component, one side of the limiting ring 7 is fixedly installed with one side of the annular seat 6, and the outer wall of the limiting ring 7 is provided with two first card slots 9, the two first card slots 9 are close to the annular seat 6, and the length direction of the first card slots 9 is arranged along the circumferential direction, and at the same time, the two first card slots 9 are centrally symmetrical about the center of the annular seat 6, and the outer wall of the limiting ring 7 is also provided with two notches 11, the notch 11 penetrates the outer wall of the limiting ring 7 along the axial direction, and the notch 11 is respectively connected with one end of one of the first card slots 9, and the notch 11 is also centrally symmetrical about the center of the annular seat 6. One side of the two arc-shaped limit plates 8 is fixedly installed with the other side of the annular seat 6. The outer wall of the arc-shaped limit plates 8 is provided with a second card slot 10. The second card slot 10 is close to the annular seat 6, and the length direction of the second card slot 10 is arranged along the circumferential direction. The two second card slots 10 are centrally symmetrical about the center of the circle of the annular seat 6. One end of the two second card slots 10 passes through one end of the arc-shaped limit plate 8, and two spacing openings 12 are formed between the two arc-shaped limit plates 8. The opening of the second card slot 10 is arranged opposite to the opening of the first card slot 9. When the annular seat 6 is rotated, the first card slot 9 and the second card slot 10 can be engaged or disengaged with the block 5 in the through hole 4 of the side cover 2.

[0040] As a preferred embodiment, see Figure 2 As shown, the width of the first card slot 9 from one end of the opening to the other end is gradually reduced, and the width of the second card slot 10 from one end of the opening to the other end is gradually reduced.

[0041] As a preferred embodiment, see Figure 2As shown, the two notches 11 and the two spacing openings 12 are staggered, that is, the two notches 11 and the two spacing openings 12 are not arranged directly opposite each other, so that when the rotating buckle 1 and the block 5 in the through hole 4 of the two side covers 2 are tightened, the block 5 is located at the narrowest width of the first slot 9 or the second slot 10 to be snapped into place.

[0042] In some other embodiments, the above-mentioned limiting rings 7 are installed on both sides of the annular seat 6, and the above-mentioned first slots 9 are opened on the limiting rings 7. The settings of the first slots 9 on both sides are the same as the settings of the above-mentioned first slots 9 and second slots 10.

[0043] In other embodiments, the arc-shaped limit plates 8 are installed on both sides of the annular seat 6, the second slots 10 are provided on the arc-shaped limit plates 8, and the second slots 10 on both sides are arranged like the first slots 9 and the second slots 10.

[0044] As a specific implementation of the sealing ring 3 , the sealing ring 3 is an annular sealing ring, wherein one sealing ring 3 is sleeved on the outer wall of the limiting ring 7 , and the other sealing ring 3 is sleeved on the outer walls of the two arc-shaped limiting plates 8 .

[0045] As a specific embodiment of the side cover 2, a through hole 4 is provided on one side of the side cover 2 close to the rotating buckle 1, and two clamping blocks 5 are provided on the inner wall of the through hole 4, and the two clamping blocks 5 are centrally symmetrical about the center of the through hole 4. A lamp installation opening 16 is provided on the side of the side cover 2 away from the rotating buckle 1, and the lamp installation opening 16 is used to install the lamp.

[0046] As a preferred embodiment, a mounting groove 17 is provided on the outer side of the mounting opening 16, and the mounting groove 17 is extended along the circumference of the mounting opening 16. In actual use, the housing of the lamp is clamped in the mounting groove 17, which prevents dust from entering the housing of the lamp and prolongs the service life of the lamp.

[0047] As a preferred embodiment, the through hole 4 includes an outer first channel portion 13 and an inner second channel portion 14 which are interconnected, the inner diameter of the first channel portion 13 is larger than the inner diameter of the second channel portion 14 , and the block 5 is installed on the inner wall of the second channel portion 14 .

[0048] As a preferred embodiment, a sealing groove 15 is provided on the connection surface between the first channel portion 13 and the second channel portion 14. The sealing groove 15 is arranged along the circumference of the through hole 4. When the rotating buckle 1 is installed and connected with the side cover 2, the sealing ring 3 is installed in the corresponding sealing groove 15. The cooperation between the sealing ring 3 and the sealing groove 15 improves the sealing performance and prevents dust from entering the lamp.

[0049] As a preferred embodiment, the outer diameter of the annular seat 6 is equal to the inner diameter of the first channel portion 13, and the outer diameter of the limiting ring 7 and the outer diameter of the two arc-shaped limiting plates 8 are equal to the inner diameter of the second channel portion 14. After the rotating buckle 1 and the side cover 2 are installed, the sealing performance can be improved to prevent dust from entering the lamp, and the outer diameters of the limiting ring 7 and the two arc-shaped limiting plates 8 are prevented from shaking in the through hole 4, thereby improving the stability of the lamp connection.

[0050] As a preferred embodiment, see Figure 3 As shown, the axial depth of the first channel portion 13 is equal to half of the axial thickness of the annular seat 6 , so that the two side covers 2 of two adjacent lamps are in close contact, thus preventing dust from entering.

[0051] As a preferred embodiment, the surface of the block 5 facing the center of the through hole 4 is arc-shaped, so that the surface of the block 5 is in close contact with the bottom inner wall of the first slot 9 or the second slot 10 to avoid shaking.

[0052] In actual use of the above-mentioned rotating clamping device, the side cover 2 is installed on two adjacent lamps, and the two clamping blocks 5 in the through hole 4 of the side cover 2 on one of the lamps slide from the notch 11 into the two first clamping grooves 9 of the limiting ring 7, and then the lamp is rotated to clamp the lamp and the rotating clamp 1, and then the two clamping blocks 5 in the through hole 4 of the side cover 2 on the other lamp slide from the spacing opening 12 between the two arc-shaped limiting plates 8 into the two second clamping grooves 10, and then the lamp is rotated. The rotation directions of the two adjacent lamps are opposite. In a vibrating environment, if the rotating clamp 1 rotates due to vibration, for example, the rotating clamp 1 rotates clockwise, due to the width of the first clamping groove 9 or the second clamping groove 10 The width must decrease gradually counterclockwise. Assuming that the width of the first slot 9 decreases gradually counterclockwise, the clockwise rotation of the rotating buckle 1 will only cause the rotating buckle 1 to be connected to the lamp on one side more and more tightly, and because the length of the first slot 9 is limited, when the block 5 rotates to the end of the first slot 9, it will limit the rotation of the rotating buckle 1; when the rotating buckle 1 rotates counterclockwise, the same as above, so no matter whether the rotating buckle 1 rotates clockwise or counterclockwise, the rotating buckle 1 and the side cover 2 will always be connected together, ensuring a stable connection between the lamps, thereby limiting the random offset of the lamps during vibration and ensuring that the lights on the work platforms are in the same straight line.
