Description

Technical Field

[0001] This utility model belongs to the field of cement pole technology, specifically relating to a thin-walled conical cement pole with a metal protective ring. Background Technology

[0002] In existing outdoor infrastructure fields such as power transmission, communication installation, and municipal lighting, thin-walled tapered cement poles are widely used in various scenarios due to their advantages such as light weight, low material consumption, and convenient transportation. The core requirement for these cement poles is to balance structural stability and outdoor damage resistance. However, existing thin-walled tapered cement poles have many technical defects in actual use and cannot meet the needs of long-term outdoor use.

[0003] First, traditional thin-walled tapered concrete poles rely primarily on the strength of the concrete material to resist external impacts, lacking specialized protective structures. Due to their thin walls, they are highly susceptible to cracking and denting after being scraped by a vehicle or struck by a heavy object, and in severe cases, they may even break. This not only incurs high repair and replacement costs but also risks causing power outages, communication failures, and other safety hazards due to pole collapse. Furthermore, while some improvements attempt to add metal protective rings to the outside of the pole, existing protective rings are mostly fixed, one-piece structures that must be fitted from the top of the pole during installation, making the process extremely cumbersome for already erected or long poles. Additionally, the roots of existing thin-walled tapered concrete poles are often directly buried in the ground or connected to the foundation via simple flanges, making the roots susceptible to corrosion and weathering due to soil compression and rainwater soaking, shortening the pole's lifespan and affecting its overall stability.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a thin-walled conical cement pole with a metal protective ring to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A thin-walled conical cement pole with a metal protective ring includes a pole body. Multiple symmetrically arranged metal rings are arranged on the outer side of the pole body. Fixing plates are provided on both sides of each metal ring. A slide rail is provided on the side wall of one end of the metal ring, and a support plate is provided on the side wall of the other metal ring. A slider is provided at one end of the support plate, passing through and slidably connected to the slide rail. Symmetrical protective boxes are provided on one side of the support plate, and symmetrical springs are provided inside each protective box. One end of each spring is connected to the side wall of the protective box, and the other end is provided with a movable block. The movable block is fitted against and slidably connected to the inner wall of the protective box. A fixing rod is provided at the other end of the movable block. The slide rail and the slider side wall both have overlapping fixing holes, and the fixing rod passes through and slidably connects to them. A handheld assembly is provided between the protective boxes.

[0007] Furthermore, a connecting box is provided at the lower end of the rod body, and a connecting block is provided inside the connecting box for threaded connection. A fixing cone is provided at the lower end of the connecting block, and a detachable connecting shell is fitted on the outside of the connecting block. The connecting shell is adapted to the connecting box, and a symmetrical mounting plate is provided on the upper side wall of the connecting shell. A symmetrical groove is provided on the bottom wall of the connecting box, and the mounting plate passes through the groove and is slidably connected to it. Screws are provided on the mounting plate and the side wall of the groove, and the depth of the fixing cone into the soil can be adjusted by rotation to adapt to different soil hardness.

[0008] Furthermore, the handheld assembly includes a handheld plate and a handheld rod. The handheld plate passes through the protective box and is connected to the side walls of the two movable blocks. The handheld plate is slidably connected to the protective box. The handheld rod is located at the center of the handheld plate, making it convenient for the operator to hold and operate. Pushing the handheld plate can simultaneously move the two movable blocks.

[0009] Furthermore, the rod body is provided with multiple L-shaped reinforcing ribs, which can enhance the internal structural strength of the rod body and disperse the radial and axial forces borne by the rod body.

[0010] Furthermore, a baffle is provided on the bottom wall of the slide rail, which is adapted to the slider to prevent the slider from sliding off the bottom of the slide rail and to ensure that the slider and the slide rail always maintain a stable connection.

[0011] Furthermore, a buffer silicone strip is provided on the outside of the metal ring. The buffer silicone strip is connected to the metal ring by glue, which can absorb the impact force when the metal ring is hit, and prevent the impact force from being directly transmitted to the rod.

[0012] Furthermore, reflective strips are provided on both sides of the metal ring. The reflective strips are pasted along the circumference of the metal ring and are made of high-brightness microprism reflective material. They can reflect light at night or in low-light environments to remind passing vehicles and pedestrians to avoid the cement pole.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) In terms of pole protection and adaptability, the multiple symmetrically arranged metal rings on the outside of the pole form a special protective structure that can directly resist external damage such as vehicle scratches and debris impacts, and prevent the pole from cracking or denting due to its thin wall thickness.

[0014] (2) The metal rings of this utility model are connected by sliding connection of slide rail and slider. The spring, moving block and fixed rod in the protective box cooperate to adjust the position of the metal ring. After the position of the metal ring is adjusted, the spring pushes the moving block to make the fixed rod pass through the fixed hole of slide rail and slider, so as to realize the stable locking of slider and slide rail, ensuring that the metal ring does not shift when used outdoors, simplifying the metal ring adjustment operation, eliminating the need for complicated tools, and improving the convenience of installation and maintenance.

[0015] (3) The workers of this utility model can adjust the soil penetration depth of the fixed cone by rotating the connecting block to adapt to soil environments with different hardness, ensuring that the fixed cone can be stably inserted into the ground, enhancing the overall stability of the rod. The detachable connecting shell is compatible with the connecting box. During installation, the connecting shell is put on the outside of the connecting block, so that the mounting plate on the connecting shell passes through the groove of the bottom wall of the connecting box and slides to the fitting position. Then, the mounting plate is fixed to the side wall of the groove by screws, which not only strengthens the connection between the connecting box and the connecting block, but also prevents rainwater and soil from entering the connection part, avoiding thread corrosion or loosening of the connection. During subsequent maintenance, the connecting shell can be removed by simply unscrewing the screws. The connection part can be inspected without damaging the structure, which solves the problems of difficult disassembly and high maintenance cost of traditional root protective shells. At the same time, it also makes up for the defects of direct buried roots being susceptible to corrosion. Attached Figure Description

[0018] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example See appendix Figure 1-5 A thin-walled conical cement pole with a metal protective ring includes a pole body 1. Multiple symmetrically arranged metal rings 2 are provided on the outer side of the pole body 1. Fixing plates 3 are provided on both sides of each metal ring 2. A slide rail 4 is provided on the side wall of one end of the metal ring 2, and a support plate 5 is provided on the side wall of the other metal ring 2. A slider 6 is provided at one end of the support plate 5, passing through and slidably connected to the slide rail 4. Symmetrical protective boxes 7 are provided on one side of the support plate 5. Symmetrical springs 8 are provided inside the protective boxes 7. One end of each spring 8 is connected to the side wall of the protective box 7, and the other end is provided with a moving block 9. The moving block 9 is fitted against and slidably connected to the inner wall of the protective box 7. A fixing rod 10 is provided at the other end of the moving block 9. The slide rail 4 and the slider 6 both have overlapping fixing holes on their side walls. The fixing rod 10 passes through the fixing holes and slidably connects to them. A handheld assembly is provided between the protective boxes 7.

[0020] A connecting box 11 is provided at the lower end of the rod body 1. A connecting block 12 is provided inside the connecting box 11 and is threadedly connected to it. A fixing cone 13 is provided at the lower end of the connecting block 12. A detachable connecting shell 14 is sleeved on the outside of the connecting block 12. The connecting shell 14 is adapted to the connecting box 11. A symmetrical mounting plate 15 is provided on the upper side wall of the connecting shell 14. A symmetrical groove is provided on the bottom wall of the connecting box 11. The mounting plate 15 passes through the groove and is slidably connected to it. Screws 16 are provided on the mounting plate 15 and the side wall of the groove. The handheld assembly includes a handheld plate 17 and a handheld rod 18. The handheld plate 17 passes through the protective box 7 and is connected to the side wall of the two moving blocks 9. The handheld plate 17 is slidably connected to the protective box 7. The handheld rod 18 is located at the center of the handheld plate 17. A baffle 20 is provided on the bottom wall of the slide rail 4. The baffle 20 is adapted to the slider 6.

[0021] First, the metal rings 2 are installed. The worker symmetrically places multiple metal rings 2 around the outside of the rod 1. The distribution of the metal rings 2 is determined based on the vulnerable areas of different tapered sections of the rod 1. During adjustment, the worker holds the handle 18 of the handheld assembly and pulls the hand plate 17 outwards. The hand plate 17 causes the two moving blocks 9 inside the protective box 7 to slide synchronously. The moving blocks 9 compress the spring 8 and cause the fixed rod 10 to retract into the protective box 7, disengaging the fixed rod 10 from the fixing hole of the slide rail 4 and the slider 6, thus releasing the lock between the slider 6 and the slide rail 4. Then, the support plate 5 connected to one side of the metal ring 2 is pushed. The slider 6 at one end of the support plate 5 slides along the slide rail 4 of the metal ring 2 on the other side. After adjustment, the hand lever 18 is released, and the spring 8 returns to its elastic deformation, pushing the moving block 9 to reset. The moving block 9 drives the fixing rod 10 through the fixing hole that coincides with the side wall of the slide rail 4 and the slider 6, relocking the slider 6 and the slide rail 4 to ensure that the position of the metal ring 2 is fixed and to prevent displacement during outdoor use. If it is necessary to increase the number of metal rings 2, the above operation can be repeated to add metal rings 2 to other areas of the pole body 1. The fixing plates 3 on both sides of the metal ring 2 can also enhance the fit stability between the metal ring 2 and the pole body 1, further improving the protective effect.

[0022] After the metal ring 2 is installed, the base of the pole 1 is fixed and assembled. The workers first screw the connecting block 12 into the connecting box 11 at the lower end of the pole 1. The depth of the fixing cone 13 into the soil is determined according to the soil hardness of the installation site. Then, the detachable connecting shell 14 is put on the outside of the connecting block 12, so that the symmetrical mounting plate 15 on the upper side wall of the connecting shell 14 is aligned with the groove on the bottom wall of the connecting box 11. The connecting shell 14 is pushed so that the mounting plate 15 passes through the groove and slides until it fits against the side wall of the groove. Then, the mounting plate 15 is fixed to the side wall of the groove with screws 16. Finally, the fixing cone 13 is aligned with the preset installation position, and the pole 1 is pressed vertically into or driven into the ground by external force so that the fixing cone 13 penetrates into the soil, thus completing the overall fixing of the pole 1.

[0023] In this embodiment, multiple L-shaped reinforcing ribs 19 are provided inside the pole body 1. During the prefabrication stage of the pole body 1, multiple L-shaped reinforcing ribs 19 are evenly embedded inside the pole body 1, so that the reinforcing ribs 19 are firmly integrated with the cement pole body 1. After the pole body 1 is installed and put into use, when facing the radial pressure generated by outdoor wind and rain, the axial tension caused by cable laying, and the stress generated by the weight of the pole body 1 itself, the L-shaped reinforcing ribs 19 can disperse these forces, preventing the thin-walled pole body 1 from bending, deforming or cracking due to concentrated force, and ensuring the long-term stable uprightness of the pole body 1.

[0024] In this embodiment, a buffer silicone strip 21 is provided on the outer side of the metal ring 2, and the buffer silicone strip 21 is connected to the metal ring 2 by adhesive. When the rod 1 is put into use, if it encounters external forces such as vehicle scratches or impacts from debris, the buffer silicone strip 21 will be the first to come into contact with the impacting object. The silicone strip absorbs the impact energy with its own flexible properties, preventing the impact force from being directly transmitted to the metal ring 2 and the rod 1. This reduces the deformation and wear of the metal ring 2 due to impact, and also prevents the rod 1 from cracking or denting due to external impact.

[0025] In this embodiment, reflective strips 22 are provided on both sides of the metal ring 2. The reflective strips 22 are attached along the circumference of the metal ring 2, and the reflective strips 22 are made of high-brightness microprism reflective material. When the pole 1 is used outdoors, at night or in low-light environments, when the headlights of passing vehicles or the light from pedestrians' lighting devices shine on the reflective strips 22, the high-brightness microprism reflective material will reflect the light back, forming a clear and bright warning area, allowing drivers and pedestrians to clearly identify the location of the concrete pole and avoid collisions with the pole 1 due to poor visibility.

[0026] In summary, when using it, the metal ring 2 should be assembled and installed first. The staff should symmetrically put it on the outside of the rod 1 and align the slide rail 4 on one side wall of the metal ring 2 with the slider 6 on the support plate 5 on the other side wall of the metal ring 2 to ensure safe assembly.

[0027] Then, grasp the handle 18 and pull the handle plate 17 outward. The handle plate 17 causes the two moving blocks 9 inside the protective box 7 to slide synchronously. The moving blocks 9 compress the spring 8 and cause the fixed rod 10 to retract into the protective box 7. The fixed rod 10 retracts into the slider 6. At this time, the slider 6 passes through the slide rail 4, ensuring that the metal ring 2 and the rod body 1 are tightly fitted. Then, release the handle 18. The spring 8 returns to its elastic deformation and pushes the moving blocks 9 to reset. The moving blocks 9 cause the fixed rod 10 to pass through the fixing hole that coincides with the side wall of the slide rail 4 and the slider 6, completing the installation and locking of the slider 6 and the slide rail 4. After this, the slider 6 and the slide rail 4 remain in a fixed state and no longer slide or adjust.

[0028] Meanwhile, a flexible protective layer is formed on the outside of the metal ring 2 by a buffer silicone strip 21 connected by adhesive, and high-brightness microprism reflective strips 22 pasted along the circumference on both sides of the metal ring 2 are also in place, preparing for protection and warning for subsequent outdoor use.

[0029] After the metal ring 2 is installed, the workers first screw the connecting block 12 into the connecting box 11 at the lower end of the rod 1. The soil insertion length of the fixing cone 13 is determined according to the soil conditions of the installation site. Then, the detachable connecting shell 14 is put on the outside of the connecting block 12, so that the symmetrical mounting plate 15 on the upper side wall of the connecting shell 14 is aligned with the groove on the bottom wall of the connecting box 11. The connecting shell 14 is pushed so that the mounting plate 15 passes through the groove and slides until it is completely in contact with the side wall of the groove. Then, the mounting plate 15 is fixed to the side wall of the groove with screws 16. This fixing not only strengthens the connection between the connecting box 11 and the connecting block 12, but also prevents rainwater and soil from entering the connection part and avoids the threads from rusting and affecting stability.

[0030] Finally, align the fixing cone 13 with the preset installation position of the pole 1, and use external force to press or drive the pole 1 vertically into the ground, so that the fixing cone 13 penetrates into the soil and completes the overall fixing installation of the pole 1. At this time, the multiple L-shaped reinforcing ribs 19 pre-set inside the pole 1 serve as an internal skeleton, which can enhance the structural strength of the pole 1 and prevent the pole 1 from bending or deforming due to force during installation or subsequent use.

[0031] During subsequent outdoor use and maintenance of the device, the slider 6 and the slide rail 4 will always remain in the fixed state as they were installed and will no longer slide. If it is necessary to inspect the root connection, the screws 16 on the mounting plate 15 can be unscrewed, the connecting shell 14 can be removed, and the threaded connection between the connecting box 11 and the connecting block 12 can be inspected or maintained. After maintenance, the connecting shell 14 can be reinstalled and the screws 16 can be fixed.

[0032] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
