Description

Technical Field

[0001] This invention relates to the field of fixture technology, specifically to a lamp holder fixing tool. Background Technology

[0002] Cargo ships cannot function without lighting during loading and unloading, especially in dimly lit or nighttime conditions. Large cargo ships typically have several lights installed on the hatch coamings. However, the lights sway significantly during navigation, which greatly reduces their lifespan. Therefore, it is necessary to manufacture fixing components for the lights.

[0003] The prior art disclosure (announcement) number CN103423715B discloses a lamp holder fixing structure, including a buffer bracket, a lower pressure plate, a rubber buffer pad, a lamp holder and a fixing shaft. The buffer bracket includes a base and two U-shaped elastic frames. When the lamp holder fixing structure is subjected to external vibration force, the two U-shaped elastic frames and the rubber buffer pad will undergo elastic deformation to form two buffer zones.

[0004] While it addresses the issue of vibration damping and securing individual LED beads within the lampshade, it fails to solve the problems of securing and damping the lampshade on the ship. Furthermore, as it involves individual LED beads, the lighting effect is generally mediocre. Existing technologies typically use floodlights for marine lighting, offering high brightness, long illumination distance, and good performance. However, floodlights usually have relatively tall lamp heads, and their lamp holders often use U-shaped mounting brackets with relatively soft supports. Moreover, the bottom-fixed design makes it easier for the heavy lamp head to vibrate more significantly. As a result, when installed on a ship, the floodlight is more prone to vibration during navigation, leading to a high failure rate over time. After a period of use, the light source will fail, requiring continuous lamp head replacement for repair, resulting in resource waste. In view of the above, we propose a lamp holder fixing fixture to solve the aforementioned problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects and provide a lamp holder fixing fixture that is structurally reasonable, highly practical, easy to fix the lamp head of the floodlight, and has a good shock absorption effect.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a lamp holder fixing fixture, comprising a fixing rod structure and fixing plates, wherein fixing plates are respectively connected to both ends of the fixing rod structure, one fixing plate is fixedly connected to one end of the fixing rod structure, and the other fixing plate is hinged to the other end of the fixing rod structure through a hinge seat, the fixing rod structure is composed of a rod one and a rod two, a screw is connected to the end of rod one along the axial direction, and an internal thread hole is provided at the end of rod two to cooperate with the screw, rod two is threadedly connected to the screw of rod one through the internal thread hole, and the rotation of rod two can change the length of the fixing rod structure and the angle between the two fixing plates.

[0007] Furthermore, the fixed rod structure is also provided with a damping mechanism. The damping mechanism is located at the end of the rod two away from the internal threaded hole. The damping mechanism includes a piston cavity, a piston body, and a sliding rod. The piston cavity is formed inside the end of the rod two. The piston body is slidably connected inside the piston cavity. The sliding rod is fixedly connected to one side of the piston rod and extends from the end of the rod two. A fixing plate is fixedly connected to the other end of the sliding rod. An inner spring is provided on each side of the piston. One inner spring is arranged around the sliding rod, and the other inner spring is placed between the other side of the piston body and the piston cavity.

[0008] Furthermore, the damping mechanism also includes a circulating oil chamber, which is an annular chamber fitted around the piston chamber. Multiple through-holes are provided circumferentially between the circulating oil chamber and the piston chamber at one end near the internal threaded hole, and multiple external oil holes are provided at the other end. These external oil holes extend from the inside of the circulating oil chamber towards the two ends of the rod. Multiple internal oil holes are correspondingly provided inside the external oil holes, and these internal oil holes are connected to the piston chamber. The mechanism also includes an adjusting cap, which is rotatably fitted onto the two ends of the rod. The inner bottom of the adjusting cap fits against the two ends of the rod to seal the internal and external oil holes. The inner bottom of the adjusting cap also has an arc-shaped concave cavity. When the adjusting cap rotates, the internal and external oil holes at the corresponding positions of the arc-shaped concave cavity can communicate with each other through the arc-shaped concave cavity.

[0009] Furthermore, the number of inner and outer oil holes is the same, and the inner and outer rings are arranged radially in correspondence.

[0010] Furthermore, the angle range of the inner and outer oil holes is less than 180 degrees, and the curvature of the arc-shaped cavity is the same as the angle of the inner and outer oil holes.

[0011] Furthermore, the piston chamber and the circulating oil chamber are filled with hydraulic oil.

[0012] Furthermore, it also includes a positioning structure that restricts the rotation of the adjusting cap. The positioning structure includes a fixed spline formed on the outer periphery of both ends of the rod and an adjusting spline formed on the outer sidewall of the adjusting cap. The fixed spline has the same external shape as the adjusting spline. It also includes a spline sleeve that is slidably connected to both ends of the rod. The spline sleeve is fitted onto both ends of the rod and can slide along its axial direction. The inner wall shape of the spline sleeve is the same as the shape of the adjusting spline or the fixed spline. When the spline sleeve is fitted onto the adjusting spline, its inner wall can simultaneously engage the adjusting spline and the fixed spline.

[0013] Furthermore, the positioning structure also includes a reinforcing ring and an outer spring. The reinforcing ring is a circular ring protruding from the outer circumference of the second rod. An outer spring is provided between the end of the reinforcing ring near the fixed spline and the spline sleeve. The outer spring is wrapped around the outer circumference of the second rod and is used to push the spline sleeve.

[0014] Furthermore, the fixing plate is provided with multiple waist holes, which are evenly arranged.

[0015] Furthermore, the fixing piece is a resilient elastic piece.

[0016] The advantages of this invention compared with the prior art are as follows: 1. Using this invention, the overall length can be conveniently adjusted through the fixed rod structure, so that when fixing the floodlight head, one end can be fixed to the head and the other end can be fixed to the fixed structure of the hull, thus achieving convenient fixing.

[0017] 2. Since one fixing plate is hinged to the fixing rod structure, the other fixing plate can be adjusted by rotating the second rod, thus adapting to the fixing of floodlights at various angles.

[0018] 3. The present invention also achieves support and fixation through the damping structure, changing the rigid connection fixation into a fixed placement with damping and shock absorption effect, thereby effectively buffering the damage caused to the lamp head by rigid fixation.

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0028] In the description of this invention, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0029] A lamp holder fixing fixture, such as Figure 2 As shown, the device includes a fixed rod structure 1 and a fixed plate 2. Fixed plates 2 are connected to both ends of the fixed rod structure 1. One fixed plate 2 is fixedly connected to one end of the fixed rod structure 1, and the other fixed plate 2 is hinged to the other end of the fixed rod structure 1 via a hinge seat 3. The hinge seat 3 facilitates adjustment of the setting angle of the fixed plate 2 on that side, increasing adjustability. Multiple waist holes 23 are evenly arranged on the fixed plate 2. Figure 1As shown, in use, any one of the fixing pieces 2 is tied to the lamp head with a cable tie. The cable tie passes through the waist hole 23 and is fitted onto the lamp head for fixation. Alternatively, a screw can be used to thread the fixing piece 2 through the waist hole 23 and screw it into the screw hole on the back of the lamp head for fixation. The other fixing piece 2 is tied to the hull fastener with a cable tie. This hull fastener can be the grille on the back of the lamp head or other fixed structure. This fixture can connect the lamp head and the fastener, thereby limiting the vibration of the lamp head and extending its service life. The fixing piece 2 can also be made of a tough elastic sheet, so that the fixing piece 2 can be wrapped around a circular column for fixation.

[0030] The fixing rod structure 1 consists of rod 4 and rod 5. Rod 4 extends along the axial direction at its end and is connected to a screw 6. Rod 5 has an internal threaded hole at its end that mates with the screw 6. Rod 5 is threadedly connected to the screw 6 of rod 4 through the internal threaded hole. Rotation of rod 5 can change the length of the fixing rod structure 1 and the angle between the two fixing pieces 2. When rod 5 rotates relative to rod 4, it can adjust the overall length of the fixing rod structure 1 to adapt to the distance between the lamp holder and the fixing component. Furthermore, as rod 5 rotates, the angle between the fixing piece 2 and the fixing component can be matched for easy fixing.

[0031] The above method achieves the connection and fixation between the lamp head and the hull, mitigating lamp head vibration to a certain extent. However, it is still a rigid fixation, and long-term use will still cause wear on the lamp head shell. Therefore, as an improvement, a damping mechanism is also provided on the fixing rod structure 1, such as... Figure 3 , Figure 4 As shown, the damping mechanism is located at the end of rod 2 5 away from the internal threaded hole. The damping mechanism includes a piston chamber 8, a piston body 9, and a slide rod 10. The piston chamber 8 is formed inside the end of rod 2 5. The piston body 9 is slidably connected inside the piston chamber 8. The slide rod 10 is fixedly connected to the side of piston rod 1 4 and extends from the end of rod 2 5. A fixing plate 2 is fixedly connected to the other end of the slide rod 10. An inner spring 11 is provided on each side of the piston. One inner spring 11 is arranged around the slide rod 10, and the other inner spring 11 is placed between the other side of the piston body 9 and the piston chamber 8. According to the above description, this can be used as an embodiment of the damping mechanism. In use, inner springs 11 are provided on both sides of the piston body 9. The extended end of the slide rod 10 is connected to a fixing member through the fixing plate 2. Thus, during vibration, the reciprocating motion of the piston continuously compresses the springs on both sides, and the vibration is reduced by the buffering effect of the springs on both sides.

[0032] As an improvement, another embodiment of the damping mechanism further includes a circulating oil chamber 12, which is an annular chamber fitted around the outer periphery of the piston chamber 8. During use, hydraulic oil should be filled into both the piston chamber 8 and the circulating oil chamber 12. Multiple through-holes 13 are provided circumferentially between the circulating oil chamber 12 and the piston chamber 8 near the internal threaded hole. These through-holes 13 ensure that the circulating oil chamber 12 and the piston chamber 8 near the screw 6 remain unobstructed, allowing hydraulic oil to freely pass through both the piston chamber 8 and the circulating oil chamber 12. Multiple external oil holes 14 are provided at the other end of the circulating oil chamber 12, extending from inside the circulating oil chamber 12 towards the end of the rod 5. Figure 5 As shown, multiple inner oil holes 15 are correspondingly provided through the inner side of the outer oil hole 14. The inner oil holes 15 are connected to the piston chamber 8. The number of inner oil holes 15 and outer oil holes 14 are the same, and the inner and outer rings are arranged radially in correspondence.

[0033] like Figure 5 As shown, it also includes an adjusting cap 16, which is rotatably sleeved onto the end of rod 2 5. It is understood that the adjusting cap 16 maintains a sealing performance against the hydraulic oil while rotating on rod 2 5, which is easily achieved using existing technology. The inner bottom of the adjusting cap 16 fits against the end of rod 2 5 to seal the inner oil hole 15 and the outer oil hole 14. The inner bottom of the adjusting cap 16 also has an arc-shaped recess 17. When the adjusting cap 16 rotates, as... Figure 6 As shown, the inner oil hole 15 and outer oil hole 14 at the corresponding positions of the arc-shaped cavity 17 can be interconnected through the arc-shaped cavity 17. In use, the arc-shaped cavity 17 can be adjusted to accommodate different numbers of inner oil holes 15 and outer oil holes 14 by rotating the adjusting cap 16. When the number of inner oil holes 15 and outer oil holes 14 is small, such as... Figure 6 As shown on the left, the passage between the piston chamber 8 at the end of rod 2 5 and the circulating oil chamber 12 is narrowed, limiting the flow rate and volume of hydraulic oil. This significantly reduces the amplitude and frequency of piston movement within the piston chamber 8 during use. Since the adjusting cap 16 is rotatable, multiple inner oil holes 15 and outer oil holes 14 can be opened according to the actual usage scenario, as shown in the right figure. At this time, the passage of hydraulic oil becomes larger, thereby increasing the amplitude and frequency of piston movement within the piston rod.

[0034] It should be noted that the angle range of the inner oil hole 15 and the outer oil hole 14 should be less than 180 degrees. The arc of the arc-shaped cavity 17 is the same as the angle of the inner oil hole 15 and the outer oil hole 14. Only in this way can the number of inner oil holes 15 and outer oil holes 14 opened be controlled by the arc-shaped cavity 17.

[0035] Since the damping mechanism is used in the event of vibration, a positioning structure is provided to limit the rotation of the adjusting cap 16 in order to prevent it from rotating automatically during vibration, such as... Figure 3 , Figure 5 , Figure 7 As shown, the positioning structure includes a fixed spline 18 formed on the outer periphery of the end of the second rod 5, and an adjusting spline 19 formed on the outer sidewall of the adjusting cap 16. The fixed spline 18 and the adjusting spline 19 have the same external shape. It also includes a spline sleeve 20 slidably connected to the end of the second rod 5. The spline sleeve 20 is fitted onto the end of the second rod 5 and can slide along its axial direction. The inner wall shape of the spline sleeve 20 is the same as that of the adjusting spline 19 or the fixed spline 18. When the spline sleeve 20 is fitted onto the adjusting spline 19, its inner wall can simultaneously engage the adjusting spline 19 and the fixed spline 18. The positioning structure also includes a reinforcing ring 21 and an outer spring 22. The reinforcing ring 21 is a raised circular ring on the outer periphery of the second rod 5, and the reinforcing ring 21 is close to the fixed spline 18. An outer spring 22 is provided between one end and the spline sleeve 20. The outer spring 22 is wrapped around the outer circumference of the second rod 5. The outer spring 22 is used to push the spline sleeve 20. In use, the spline sleeve 20 is pushed down to compress the outer spring 22, so that the inner wall of the spline sleeve 20 is disengaged from the adjusting spline 19, so that the adjusting cap 16 can rotate freely. After the rotation adjustment is completed, the fixed spline 18 and the adjusting spline 19 are matched in shape. Then the spline sleeve 20 is released. Under the push of the outer spring 22, the spline sleeve 20 will put the adjusting spline 19 into place and achieve the effect of positioning it. The fixed spline 18 is fixed to the outer wall of the second rod 5. It can prevent the spline sleeve 20 from rotating and then restrict the rotation of the adjusting cap 16 through the meshing relationship.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only a part of the embodiments of the present invention, not all of them. The actual structure is not limited thereto. In short, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
