Description
Technical Field
[0001] The present invention relates to the field of lighting safety equipment, and particularly to a folding lamp hook with a telescopic safety rope. Background Art
[0002] In the field of stage lighting equipment, in order to create a dynamic stage effect, the installation of lighting fixtures is divided into two types: long-term fixed installation (such as in scenarios like TV studio, theater, auditorium, etc.) and mobile performances (such as in large-scale celebrations, star concerts, etc. where repeated disassembly and assembly are required to adapt to different stages). During the installation of these lighting fixtures, to ensure stability and the safety of personnel at the performance venue, the base of the lighting fixture needs to be connected to the installation bracket through a safety rope to prevent the lamp hook from failing or installation operation errors from causing the lighting fixture to fall from a height, playing a secondary protection role. For example, Figure 1 as shown in the telescopic safety rope of a lighting fixture in the prior art, it can be determined that Figure 1 the box body 100 in [reference] only has one telescopic safety rope 300, and the safety rope 300 is connected with a buckle 400. When using this telescopic safety rope, the box body 100 will be fixed on the lighting fixture, and the buckle 400 will lead the safety rope 300 to bypass the installation frame of the lighting fixture and then buckle back on the safety rope. The usage method is relatively single, and if the lighting fixture falls from the installation frame, it only relies on a single safety rope to bear the weight, and there are no further safety measures. Summary of the Invention
[0003] The purpose of the present invention is to solve the above technical problems and provide a folding lamp hook with a telescopic safety rope that has a richer usage method.
[0004] A folding lamp hook with a telescopic safety rope includes a hook, a fixing plate, a box body, a wire reel, a first safety rope, and a second safety rope. The box body includes an upper box body and a lower box body that are assembled up and down. The box body is fixed on the fixing plate, and the fixing plate is fixed on the lighting fixture. The hook is rotatably installed on the fixing plate, and the box body does not hinder the flipping action of the hook. The hook is used for hanging on the lighting fixture installation frame. The wire reel is rotatably installed inside the box body. The wire reel includes an upper wheel disc and a lower wheel disc that are assembled up and down. One end of the first safety rope and the second safety rope is a limiting end, and the limiting end is looped around the wire reel. The other end of the first safety rope and the second safety rope is a free end, and the free ends extend out of the two sides of the box body respectively. The first safety rope and the second safety rope can freely stretch under the drive of the wire reel. The ends of the free ends of the first safety rope and the second safety rope respectively form a fixing loop, and at least one of the fixing loops is connected with a buckle. The first safety rope and the second safety rope are hung on the lighting fixture installation frame where the hook is hung, or the first safety rope and the second safety rope are respectively hung on different lighting fixture installation frames.
[0005] The folding lamp hook with a telescopic safety rope according to the present application uses a folding lamp hook to install a lamp, hanging the lamp on a lamp mounting bracket to create a stage lighting effect. After the lamp is used, when the lamp is stored, the folding lamp hook can be folded from the use state to the storage state, thus reducing the space occupied and enabling the lamp to be stored in a smaller space. Configuring the box body not to hinder the flipping action of the hook can avoid the folding of the box body and the hook. In addition, the present application also adopts a double-rope structure. Compared with the existing folding lamp hook with a single telescopic safety rope, under the same specifications, the height of the rope outlet of the folding lamp hook with a double telescopic safety rope in the present application will be reduced, which can reduce the impact force on the safety rope when the lamp has a falling accident; when the first safety rope and the second safety rope are simultaneously hung on the lamp mounting bracket, the load-bearing capacity of the folding lamp hook with a telescopic safety rope can be doubled. The first safety rope and the second safety rope are respectively wound around different mounting brackets, and a double-insurance structure can also be formed. Due to the addition of the safety rope, the usage method of the folding lamp hook with a telescopic safety rope is also richer.
[0006] Further, the hook includes a hook body and a connecting seat. The lower part of the connecting seat is rotatably installed on the fixing plate, and the hook body is flipably installed on the upper part of the connecting seat. Rotating the connecting seat makes the box body not hinder the flipping action of the hook body.
[0007] Still further, the hook includes a hook body and a connecting seat. The lower part of the connecting seat is rotatably installed on the fixing plate, and the hook body is flipably installed on the upper part of the connecting seat. It also includes a limiting surface for limiting the flipping angle of the hook body, and the limiting surface limits the flipping action of the hook body outside the box body.
[0008] Still further, it also includes a torsion spring. A cavity is provided in the middle of the wire reel, and a shaft body is provided on the box body. The shaft body extends into the cavity to form an installation cavity for installing the torsion spring. The fixed end of the torsion spring is clamped on the shaft body, and the movable end of the torsion spring is clamped on the wire reel; the torsion spring provides a restoring elastic force for the first safety rope and the second safety rope. The torsion spring can store elastic force when the first safety rope and the second safety rope are pulled out of the box body, and release the elastic force when the first safety rope and the second safety rope retract, so that the first safety rope and the second safety rope are reset.
[0009] Still further, the wire reel extends towards the cavity to form an extension ring surrounding the installation cavity, and a through hole for the shaft body to pass through is provided in the middle of the extension ring. The extension ring can cooperate with the shaft body to make the wire reel rotate around the shaft body more stably without making abnormal noises by moving randomly in the box body, and the extension ring can also provide a limit for the torsion spring to prevent the torsion spring from detaching from the installation cavity.
[0010] Furthermore, the winding wheel is provided with a rope winding body for winding a rope, and two limiting grooves, two clamping grooves and two first wire outlets are arranged in a centrally symmetrical manner in the rope winding body, and the limiting ends of the first safety rope and the second safety rope are respectively limitedly installed on the two limiting grooves, and the limiting groove is connected to the first wire outlet through the clamping groove, and the rope body led out from the limiting end is first clamped in the clamping groove, and then led out from the first wire outlet and wound around the rope winding body. The limiting end of the first safety rope or the second safety rope is first limited by the limiting groove, and then the clamping groove clamps and limits the rope body led out from the limiting groove, so as to prevent the safety rope from transmitting the action to the limiting end when it is extended and retracted, thereby preventing the limiting end from repeatedly rubbing in the limiting groove and causing the limiting structure to fail, and forming a dual limiting structure of the limiting groove and the clamping groove, thereby forming a more efficient limiting structure of the safety rope.
[0011] Furthermore, the clamping groove is provided with a limit spike, which penetrates into the rope body to limit the position. The limit spike can better clamp the rope body to prevent the rope body from shifting in the clamping groove, and cooperate with the limit groove to form a variety of limit structures, so that the installation performance of the product is stronger.
[0012] Furthermore, the upper wheel and the lower wheel are assembled to form the rope winding body, and the limit spikes in the clamping groove of the upper wheel are staggered with the limit spikes in the clamping groove of the lower wheel. The winding wheel is divided into two parts, which is convenient for installing each part on the winding wheel. The limit spikes are arranged in the clamping grooves of the upper wheel and the lower wheel to improve the limit effect. The staggered setting of the limit spikes can avoid the upper and lower limit spikes from acting on the same position of the rope body, thereby minimizing the limit spikes from damaging the rope body.
[0013] Furthermore, the box body is provided with two second wire outlets, and the two second wire outlets are both provided with protective covers, and the first safety rope and the second safety rope are respectively passed through the two protective covers.
[0014] Furthermore, the free ends of the first safety rope and the second safety rope are respectively wrapped around to form a fixing ring, and at least one of the fixing rings is connected to a locking buckle.
[0015] Furthermore, the upper box body and the lower box body are fixedly connected via a threaded connection structure, and a drain port is provided on the bottom surface of the lower box body, which can conveniently drain water in the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A folding lamp hook with a telescopic safety rope according to the present invention will be described in conjunction with the accompanying drawings.
[0038] As Figures 2 to 21 shown, the folding lamp hook with a telescopic safety rope includes a hook 8, a fixing plate 7, and a telescopic safety rope. The fixing plate 7 is fixed on the lamp. The hook 8 is rotatably installed on the fixing plate 7. The lamp is hung on the lamp mounting bracket through the hook 8. The telescopic safety rope is also fixed on the fixing plate 7 and is hung on the lamp mounting bracket through the telescopic safety rope to provide insurance for the hook 8, so that when the hook 8 falls off, the lamp will not fall directly, but will be continuously hung on the lamp mounting bracket by the telescopic safety rope.
[0039] As Figures 2 to 5 shown, a telescopic safety rope includes a box body 1, a wire reel 2, a first safety rope 3, and a second safety rope 4. The box body 1 is fixed on the lamp. The wire reel 2 is rotatably installed inside the box body 1. One end of the first safety rope 3 and the second safety rope 4 is a limiting end, and the limiting end is looped around the wire reel 2. The other end of the first safety rope 3 and the second safety rope 4 is a free end, and the free ends respectively extend to the outside from two sides of the box body 1. Fixing rings (31, 41) are respectively formed at the ends of the free ends of the first safety rope 3 and the second safety rope 4. A buckle 5 is connected to at least one of the fixing rings (31, 41). In the embodiment shown in the drawings of the present application, a buckle 5 is connected to the fixing ring (31, 41) of the first safety rope 3, and no buckle 5 is connected to the fixing ring (31, 41) of the second safety rope 4. The first safety rope 3 and the second safety rope 4 can freely expand and contract under the drive of the wire reel 2. The telescopic safety rope with double outgoing ropes adopted in the present application can reduce the impact of the safety rope when the lamp falls and significantly improve the load-bearing capacity of the safety rope. It is suitable for more installation environments, and the first safety rope 3 and the second safety rope 4 can also be respectively hung on different mounting brackets to form a double-insurance structure.
[0040] As Figure 3As shown, it further includes a coil spring 6. A cavity is provided in the middle of the wire winding wheel 2. A shaft body 16 is provided on the box body 1. The shaft body 16 extends into the cavity to form an installation cavity 23 for installing the coil spring 6. The fixed end 61 of the coil spring 6 is clamped on the shaft body 16, and the movable end 62 of the coil spring 6 is clamped on the wire winding wheel 2. The coil spring 6 provides a restoring elastic force for the first safety rope 3 and the second safety rope 4.
[0041] As Figure 4 shown, the wire winding wheel 2 extends towards the cavity to form an extension ring 231 surrounding the installation cavity 23. A through hole 232 for the shaft body 16 to pass through is provided in the middle of the extension ring 231. The extension ring 231 can be in clearance fit with the shaft body 16, enabling the wire winding wheel 2 to stably rotate around the shaft body 16 without making abnormal noises due to random movement in the box body 1. Moreover, the extension ring 231 can also provide a limit for the coil spring 6 to prevent the coil spring 6 from detaching from the installation cavity 23.
[0042] As Figure 3 and Figure 4 shown, a first clamping position 161 is provided on the shaft body 16. The fixed end 61 of the coil spring 6 is bent so that it can be clamped into the first clamping position 161 for fixation. A second clamping position 233 is provided on the extension ring 231. The movable end 62 of the coil spring 6 is bent so that it can be clamped into the second clamping position 233 and rotate with the rotation of the wire winding wheel 2. This enables the coil spring 6 to accumulate elastic force when the first safety rope 3 and the second safety rope 4 are pulled out of the box body 1, and release the elastic force when the first safety rope 3 and the second safety rope 4 retract, causing the first safety rope 3 and the second safety rope 4 to reset with the rotation of the wire winding wheel 2.
[0043] As Figures 3 to 5 shown, two limiting grooves 241 are symmetrically provided on the wire winding wheel 2. The axis of symmetry is the connecting line of the centers of the limiting grooves 241, or the line passing through the center of the wire winding wheel 2 between the two limiting grooves 241, or the two limiting grooves 241 can coincide after rotating 180 degrees. The limiting ends of the first safety rope 3 and the second safety rope 4 are respectively installed in the two limiting grooves 241 in a limiting manner. The limiting ends of the first safety rope 3 and the second safety rope 4 are limiting spheres (32, 42). The limiting spheres (32, 42) are accommodated in the limiting grooves 241, and the rope bodies led out from the limiting ends extend out of the limiting grooves 241 from the outlets of the limiting grooves 241. Since the size of the limiting spheres (32, 42) is larger than the size of the outlets of the limiting grooves 241, the limiting ends of the first safety rope 3 and the second safety rope 4 are respectively installed in the two limiting grooves 241 in a limiting manner.
[0044] As Figures 3 to 5As shown, the rope winding body 24 for winding the rope is provided on the winding wheel 2. The limiting groove 241 is arranged inside the rope winding body 24. Two clamping grooves 242 and two first wire outlets 243 are further provided on the rope winding body 24. The clamping grooves 242 and the first wire outlets 243 are arranged in a centrosymmetric manner. The outlet of the limiting groove 241 is the clamping groove 242, and the limiting groove 241 communicates with the first wire outlet 243 through the clamping groove 242. That is, after the winding wheel 2 is rotated 180 degrees, the two limiting grooves 241, the two clamping grooves 242, and the two first wire outlets 243 can coincide. The rope body led out from the limiting end is first clamped in the clamping groove 242 and then led out from the first wire outlet 243 and wound around the rope winding body 24. The clamping groove 242 clamps and limits the rope body led out from the limiting groove 241, preventing the action of the safety rope during telescoping from being transmitted to the limiting end, and thus avoiding the failure of the limiting structure caused by repeated friction of the limiting end in the limiting groove 241. Therefore, the service life of the telescopic safety rope can be increased by clamping the rope body through the clamping groove 242, as Figure 5 shown, the rope body of the second safety rope 4 finally leads out from the first wire outlet 243.
[0045] As Figure 2 and Figure 3 shown, two second wire outlets are provided on the box body 1, and protective sleeves 17 are provided at the two second wire outlets. The first safety rope 3 and the second safety rope 4 pass through the protective sleeves 17, thereby preventing the first safety rope 3 and the second safety rope 4 from cutting the box body 1 during telescoping.
[0046] As Figure 3 shown, limiting spikes 2421 are provided in the clamping groove 242. The limiting spikes 2421 pierce into the rope body for limiting. The limiting spikes 2421 can better clamp the rope body, prevent the rope body from shifting in the clamping groove 242, and cooperate with the limiting groove 241 to form a variety of limiting structures, making the installation performance of the product stronger. The limiting spikes 2421 are designed with a narrow top and a wide bottom, which can not only effectively pierce into the rope body to achieve limiting but also avoid cutting and damaging the rope body.
[0047] As Figure 3 and Figure 4As shown, the wire winding wheel 2 includes an upper wheel disc 21 and a lower wheel disc 22. The upper wheel disc 21 and the lower wheel disc 22 are joined together to form the rope winding body 24. Two limiting grooves 241, two clamping grooves 242, and two first wire outlets 243 on the wire winding wheel 2 respectively form two sets of structures for clamping the safety rope. At least two limiting grooves 241 and two clamping grooves 242 are formed by the joining of the upper wheel disc 21 and the lower wheel disc 22. The limiting spikes 2421 in the clamping groove 242 of the upper wheel disc 21 are arranged in a staggered manner with the limiting spikes 2421 in the clamping groove 242 of the lower wheel disc 22. While improving the limiting effect, the staggered arrangement of the limiting spikes 2421 can prevent the upper and lower limiting spikes 2421 from acting on the same position of the rope body, thereby reducing the damage to the rope body. There are two fixing positions for the joining of the upper wheel disc 21 and the lower wheel disc 22 between the two sets of clamping safety box structures. The fixing positions include a fixing convex position 244 and a fixing concave position 245. One of the two mounting positions of the upper wheel disc 21 is a fixing convex position 244, and the other is a fixing concave position 245. The lower wheel disc 22 is also provided with a fixing convex position 244 and a fixing concave position 245. The fixing convex position 244 of the upper wheel disc 21 is aligned with the fixing concave position 245 of the lower wheel disc 22, and the other fixing convex position 244 and fixing concave position 245 are also arranged opposite to each other. A screw hole is provided on the fixing convex position 244. The fixing convex position 244 and the fixing concave position 245 are connected by screws to form the wire winding wheel 2. A positioning post 2451 is provided on the fixing concave position 245, and a positioning groove 2441 is provided on the fixing convex position 244. The positioning post 2451 and the positioning groove 2441 cooperate to position when the upper wheel disc 21 and the lower wheel disc 22 are joined. This setting can balance the weights of the upper wheel disc 21 and the lower wheel disc 22, enabling the wire winding wheel 2 to maintain balance during rotation and avoiding severe wear on one side of the wheel disc.
[0048] As Figure 3 shown, the box body 1 includes an upper box body 14 and a lower box body 15. The upper box body 14 and the lower box body 15 are fixedly connected through a threaded connection structure 12. In addition, as Figure 2 and Figure 3 shown, the present application also improves the drain port 13. The drain port 13 is arranged on the bottom surface of the lower box body 15. The inlet of the drain port 13 is kept flush with the bottom surface of the lower box body 15, or is arranged at the lowest point of the bottom surface of the lower box body 15 to avoid water accumulation on the bottom surface of the lower box body 15. The outlet of the drain port 13 extends a drain groove towards the side surface of the lower box body 15, so that the water flowing out of the box body 1 can flow out along the drain groove.
[0049] As Figure 2 , Figure 3 and Figure 6As shown, a first fixing hole 11 is provided in the middle of the box body 1. The first fixing hole 11 is arranged in the middle of the shaft body 16. A second fixing hole is provided at the position of the fixing plate 7 corresponding to the first fixing hole 11. The box body 1 and the fixing plate 7 are connected and fixed by a connecting member 9 passing through the first fixing hole 11 and the second fixing hole. When the first fixing hole 11 and the second fixing hole are through holes, two connecting members 9 can be used to be threadedly connected up and down to clamp and fix the fixing plate 7 and the box body 1. When the first fixing hole 11 and the second fixing hole are threaded holes, a bolt connecting member 9 can be directly used to connect the first fixing hole 11 and the second fixing hole, so as to connect and fix the fixing plate 7 and the box body 1. In addition, the fixing plate 7 also utilizes the threaded connection structure 12 between the upper box body 14 and the lower box body 15, and further connects and fixes the fixing plate 7 and the box body 1 through the shared threaded connection structure 12.
[0050] Embodiment 1
[0051] As Figures 6 to 10 shown, the hook 8 includes a hook body 81 and a connecting seat 82. The lower part of the connecting seat 82 is rotatably installed on the fixing plate 7, and the hook body 81 is flipably installed on the upper part of the connecting seat 82. Rotate the connecting seat 82 so that the box body 1 does not hinder the flipping action of the hook body 81.
[0052] As Figure 6 and Figure 7 shown, the hook body 81 includes a folding connection head 811, a main hook body 812, a sub-hook body 813 and a connection locking member 814. The main hook body 812, the sub-hook body 813 and the connection locking member 814 cooperate with each other to form a clamping cavity that can clamp the lamp mounting bracket. The hook body 81 can be locked and unlocked through the connection locking member 814. The folding connection head 811 is arranged on the main hook body 812. The connecting seat 82 includes a bottom surface 822, a connecting surface 823, a back surface 824 and a connecting rotating shaft 821. The connecting rotating shaft 821 passes through the bottom surface 822 and the fixing plate 7. Limited positions are provided at both ends of the connecting rotating shaft 821. The limited positions are used in cooperation with the bottom surface 822 and the fixing plate 7 to limit the position, so as to prevent the connecting rotating shaft 821 from falling off the fixing plate 7. Two connecting surfaces 823 are provided and are respectively arranged on both sides of the bottom surface 822. A turning shaft 83 is fixed on the two connecting surfaces 823. The turning shaft 83 passes through the folding connection head 811. The hook body 81 is flipably installed on the connecting seat 82 through the folding connection head 811 and the rotatable shaft. As Figure 6 and Figure 8As shown, since the connecting seat 82 is rotatable, when it is necessary to fold and store the hook body 81, the hook body 81 can be rotated to the outside of the retractable safety rope and then folded and stored, so that the box body 1 does not hinder the flipping movement of the hook body 81. The back surface 824 connects the two connecting surfaces 823 and the bottom surface 822. The back surface 824 can cooperate with the bottom surface 822 to form a flipping limit structure for the hook body 81. When the hook body 81 is folded and stored, it can be limited by the bottom surface 822 so that the hook body 81 can be on the same horizontal plane as the retractable safety rope, or there are some areas on the same horizontal plane. The hook body 81 in the working state is limited by the back surface 824 to keep the hook body 81 in a vertical state and better hang on the lamp connecting bracket.
[0053] As Figure 9 and Figure 10 shown, another form of the hook body 81 is provided. The structure is the same as that of the attached Figure 6 scheme, the difference is that: the hook body 81 of this form does not generally enclose a clamping cavity as the hook body 81 of the attached Figure 6 and Figure 8 Instead, the auxiliary hook body 813 passes through the main hook body 812, so that the auxiliary hook body 813 and the main hook body 812 cooperate to form a "C"-shaped clamping cavity. Therefore, when storing this hook body 81, the rotatable connecting seat 82 and the "C"-shaped clamping cavity can be used in cooperation, so that the box body 1 of the retractable safety rope can be accommodated or partially accommodated in the "C"-shaped clamping cavity, thereby saving the space required by the hook body 81 during storage.
[0054] Embodiment 2
[0055] As Figures 11 to 21 shown, the hook 8 includes a hook body 81 and a connecting seat 82. The lower part of the connecting seat 82 is rotatably installed on the fixing plate 7, the hook body 81 is flipably installed on the upper part of the connecting seat 82, and further includes a limiting surface for limiting the flipping angle of the hook body 81. The limiting surface limits the flipping movement of the hook body 81 outside the box body 1.
[0056] As Figures 11 to 14 shown, most of the structures in this embodiment are the same as those in Embodiment 1. The difference from Embodiment 1 is that the connecting seat 82 in this embodiment is directly fixed on the fixing plate 7, such as by welding or directly integrally formed with the fixing plate 7. The bottom surface 822 of the connecting seat 82 is the top surface of the fixing plate 7. The back surface 824 and the bottom surface 822 of the connecting seat 82 cooperate to make the flipping direction of the hook body 81 face the outside of the retractable safety rope, and the flipping movement of the hook body 81 is limited outside the box body 1. And the connecting seat 82 in this embodiment is also provided with an intermediate connecting surface 823. The intermediate connecting surface 823 extends a limiting convex block 826 through the back surface 824 to the upper surface of the box body 1. Through the limitation of the limiting convex block 826, the box body 1 is more stably fixed on the mounting plate.
[0057] As Figures 15 to 18 shown, most of the structures in this embodiment are the same as those in the first embodiment. The difference from the first embodiment is that the connecting seat 82 in this embodiment is directly fixed on the fixing plate 7, such as by welding or directly integrally formed with the fixing plate 7. The bottom surface 822 of the connecting seat 82 is the top surface of the fixing plate 7. The direction of the hook body 81 flipped by the cooperation of the back surface 824 and the bottom surface 822 of the connecting seat 82 faces the outside of the telescopic safety rope, restricting the flipping action of the hook body 81 outside the box body 1. And the connecting seat 82 in this embodiment is also provided with an intermediate connecting surface 823. The intermediate connecting surface 823 extends through the back surface 824 to the upper surface of the box body 1 with a limiting cross bar 826. And the limiting cross bars 826 of two adjacent connecting seats 82 are connected as a whole and directly pressed on the box body 1, making the box body 1 more stably fixed on the mounting plate.
[0058] As Figures 19 to 21 shown, most of the structures in this embodiment are the same as those in the first embodiment. The difference from the first embodiment is that the connecting seat 82 in this embodiment is directly fixed on the fixing plate 7, such as by welding or directly integrally formed with the fixing plate 7. The bottom surface 822 of the connecting seat 82 is raised to be flush with the top surface of the box body 1 or higher than the top surface of the box body 1, and the connecting surface 823, the back surface 824 and the turning shaft 83 are correspondingly raised.
