Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED landscape lighting technology, specifically to a pole mounting device for floodlights. Background Technology
[0002] In LED landscape lighting projects, many high-rise or multi-story buildings that want to present overall brightness and create an atmosphere will use external floodlighting and pole-mounted installation to achieve this.
[0003] Currently, the connection between floodlights and poles mostly adopts a ring-shaped pressure plate structure. The principle is to use an arc-shaped pressure plate to fit against the outer wall of the pole, and then use screws that pass through the pressure plate to fasten the lamp base to the pressure plate. The pre-tightening force of the screws makes the pressure plate fit tightly against the pole, thereby fixing the lamp.
[0004] However, in actual use, the continuous vibration of the lamps under wind, the corrosion of screws caused by rainwater, and the material fatigue caused by long-term load all exacerbate the loosening of the screws. When the screws loosen, the tightness of the fit between the ring-shaped pressure plate and the pole decreases, inevitably creating gaps. As the gaps widen, the lamps lose stable constraints and are prone to positional deviation, causing the lighting angle to deviate from the preset range, affecting the lighting effect or monitoring accuracy. More seriously, if the gaps widen further, it may cause the entire lamp to loosen or even fall off, not only causing equipment damage but also potentially posing a safety hazard to pedestrians or facilities below. Utility Model Content
[0005] The purpose of this utility model is to provide a pole-mounted installation device for floodlights to solve the problems mentioned in the background section. To solve these technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a pole mounting device for floodlights, comprising:
[0007] The mounting components include a first clamping plate, a second clamping plate, a screw, and a nut. The first and second clamping plates are both clamped and connected to the upper two ends of the outer surface of the upright. The screw is inserted and connected inside the first and second clamping plates, and the nut is threaded and connected to the outside of the screw.
[0008] The locking component includes an upper limit ring, a lower limit ring, a guide rod, and a locking frame. The middle part of the upper limit ring is sleeved on the upper part of the outer surface of the upright, and the middle part of the lower limit ring is sleeved on the lower part of the outer surface of the upright. The guide rods are fixed on both sides of the outer surfaces of the upper limit ring and the lower limit ring, respectively. The guide ring is movably connected to the outside of the guide rod, and the locking frame is located at the bottom of the guide ring.
[0009] Furthermore, the bottom of the upper limit ring presses against the top of the first and second circling pressure plates, and the top of the lower limit ring presses against the bottom of the first and second circling pressure plates.
[0010] Furthermore, a vertical plate is fixedly connected between the two locking frames, and the locking frames are locked to the outside of the nuts and screws.
[0011] Furthermore, a hole is provided in the middle of the upright plate, and support rods are provided on both sides of the upper limit ring and the lower limit ring, and the support rods are inserted and connected inside the hole.
[0012] Furthermore, a rubber disc is bonded to the outer side of the support rod, and a lamp body is provided at the outer end of the first circumferential pressure plate.
[0013] Furthermore, it also includes a support component, which includes a limiting plate, a positioning ring, and a positioning slot. The limiting plate is fixedly connected to the outside of the guide rod, the positioning ring is disposed on one side of the guide ring, and the positioning slot is opened inside the limiting plate, with the positioning ring inserted and connected inside the positioning slot.
[0014] Furthermore, both the positioning ring and the positioning slot are evenly distributed and are arc-shaped.
[0015] This utility model has the following beneficial effects:
[0016] This utility model, through its locking components, uses an upper and lower limit ring to axially limit the first and second circumferential pressure plates from the top and bottom, directly restricting their vertical sliding on the upright. Simultaneously, the locking frame's shape-matching design with the screws and nuts provides radial constraint on the fasteners, preventing relative rotation between the screws and nuts. Combined with the compression deformation of the rubber disc after the support rod is inserted into the hole, this creates a dual fixation of "axial limitation + radial locking," completely solving the problem of gaps caused by loose screws in traditional structures. This ensures the circumferential pressure plates and the upright are always tightly fitted, guaranteeing the long-term stability of the lamp after installation and avoiding the risk of positional displacement or detachment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figures 1-4 As shown, this utility model is a pole mounting device for floodlights, comprising:
[0029] The mounting components include a first clamping plate 11, a second clamping plate 12, a screw 14, and a nut 15. The first clamping plate 11 and the second clamping plate 12 are both clamped and connected to the upper two ends of the outer surface of the upright. The screw 14 is inserted and connected inside the first clamping plate 11 and the second clamping plate 12. The nut 15 is threaded to the outside of the screw 14.
[0030] The locking component includes an upper limit ring 21, a lower limit ring 22, a guide rod 23, and a locking frame 27. The middle part of the upper limit ring 21 is sleeved on the upper part of the outer surface of the upright, and the middle part of the lower limit ring 22 is sleeved on the lower part of the outer surface of the upright. The guide rod 23 is fixed on both sides of the outer surface of the upper limit ring 21 and the lower limit ring 22 respectively. The guide ring 26 is movably connected to the outside of the guide rod 23, and the locking frame 27 is set at the bottom of the guide ring 26.
[0031] After the first and second circumferential clamping plates 11 and 12 have completed their initial clamping against the outside of the upright, when the upright plate 28 is pushed, the guide ring 26 slides axially along the guide rod 23, causing the locking frame 27 to move synchronously. Since the shape of the locking frame 27 matches the screw 14 and nut 15, it can precisely fit around the screw 14 and nut 15 used to fasten the clamping plates. This physical enclosure restricts the circumferential rotation of the screw 14 and nut 15, preventing loosening of the fasteners due to vibration or other external forces, and further enhancing the fixing strength of the clamping plates.
[0032] The bottom of the upper limit ring 21 presses against the top of the first and second circumferential pressure plates 11 and 12, and the top of the lower limit ring 22 presses against the bottom of the first and second circumferential pressure plates 11 and 12.
[0033] The upper limit ring 21 and the lower limit ring 22 limit the clamping pressure plate 11 and clamping pressure plate 22 from the top and bottom, respectively. The axial constraint of the limit rings can prevent the clamping pressure plate 11 and clamping pressure plate 22 from displacing in the axial direction of the upright, thus initially limiting their movement space and laying the foundation for subsequent locking.
[0034] A vertical plate 28 is fixedly connected between the two locking frames 27, and the locking frames 27 are locked to the outside of the nut 15 and the screw 14;
[0035] After the first clamping plate 11 and the second clamping plate 12 are clamped on the outside of the upright, the screw 14 passes through the inside of the first clamping plate 11 and the second clamping plate 12. Then, the nut 15 is screwed and fixed on the outside of the screw 14, so that the first clamping plate 11 and the second clamping plate 12 are installed and fixed on the outside of the upright.
[0036] The upright plate 28 has a hole 29 in the middle. Support rods 24 are provided on both sides of the upper limit ring 21 and the lower limit ring 22. The support rods 24 are inserted and connected inside the hole 29.
[0037] A rubber disc 25 is bonded to the outside of the support rod 24, and a lamp body 13 is provided at the outer end of the circumferential pressure plate 11.
[0038] The support rod 24 moves synchronously with the upright plate 28 and is inserted into the hole 29. During the insertion process, the rubber disc 25 at the end of the support rod 24 is deformed by the pressure of the edge of the hole 29, allowing it to pass smoothly through the hole 29. After the rubber disc 25 has completely passed through the hole 29, it unfolds due to elastic recovery and blocks the outside of the upright plate 28, forming a mechanical locking structure.
[0039] Working principle: After the first and second clamping plates 11 and 12 are initially clamped against the outside of the upright, the screw 14 passes through the pre-set through holes inside both plates. Then, the nut 15 is screwed onto the outside of the screw 14. The axial pressure generated by the thread engagement between the screw 14 and the nut 15 forces the first and second clamping plates 11 and 12 to fit tightly against the surface of the upright. The upper limit ring 21 is pressed against the top of both plates, and the lower limit ring 22 is pressed against the bottom of both plates. After the limiting is completed, when the upright plate 28 is pushed, the guide ring 26 moves along the axial direction of the guide rod 23. The sliding motion causes the locking frame 27 to move synchronously. Since the inner cavity shape of the locking frame 27 perfectly matches the outer contour of the screw 14 and nut 15, it can be precisely fitted onto the outside of the screw 14 and nut 15. During the movement of the upright plate 28, the support rod 24 is inserted into the hole 29 synchronously with the upright plate 28. The rubber disc 25 at the end of the support rod 24 undergoes elastic deformation due to the radial constraint of the hole 29. After contraction, it penetrates the hole 29. When the rubber disc 25 completely passes through the hole 29, it recovers its elasticity and unfolds. Its outer diameter is larger than the diameter of the hole 29, thus blocking the outside of the upright plate 28.
[0040] This step, through multi-dimensional mechanical coordination, forms a synergistic effect, comprehensively restricting the displacement freedom of the first and second circumferential clamping plates 11 and 12, ultimately ensuring the long-term stable fixation of the installation device on the pole.
[0041] Please see Figure 1 , Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0042] The supporting component includes a limiting plate 31, a positioning ring 32, and a positioning slot 33. The limiting plate 31 is fixedly connected to the outside of the guide rod 23. The positioning ring 32 is disposed on one side of the guide ring 26. The positioning slot 33 is opened inside the limiting plate 31, and the positioning ring 32 is inserted into and connected inside the positioning slot 33.
[0043] Since the locking frame 27 is connected to the guide ring 26, after the guide ring 26 is fixed, the locking frame 27 is also positioned in a specific position, realizing the separation and positioning between the locking frame 27 and the screw 14 and nut 15. This separation state ensures that the screw 14 and nut 15 will not be interfered with by the locking frame 27 during the installation of the first and second ring clamping plates 11 and 12, making it convenient for operators to adjust the position and initially fix the first and second ring clamping plates 11 and 12.
[0044] The positioning rings 32 and the positioning slots 33 are both evenly distributed and are both arc-shaped.
[0045] Working principle: As the guide ring 26 moves, the positioning insert ring 32 connected to it moves synchronously and eventually inserts into the interior of the positioning slot 33. Since the locking frame 27 is connected to the guide ring 26, after the position of the guide ring 26 is fixed, the locking frame 27 is also positioned in a specific position.
[0046] In this step, due to the stable fit between the positioning ring 32 and the positioning slot 33, the guide ring 26 and the locking frame 27 will not move unexpectedly, ensuring the stability of the position of each component throughout the installation process.
