Description

Technical Field

[0001] The present application belongs to the technical field of lamp poles, and in particular, relates to a lamp pole. Background Art

[0002] Street lamps are lamps that provide lighting for roads, and generally refer to lamps within the range of road lighting in traffic lighting. With the accelerated pace of urban public facilities construction in my country, the gradual improvement of urban and rural infrastructure, the demand for street lamps is also increasing.

[0003] Most of the existing street lamps are integrally formed, and most of the street lamp poles are more than 6 to 10 meters long. The poles are too long, which increases the difficulty of production and the production cost. It is inconvenient to transport, store and install the poles. When the poles are too long, they can only be transported by large trucks. When the construction area is remote, the difficulty of transportation is greatly increased, the transportation cost increases exponentially and there is a waste of transportation resources. To solve the above problems, it is necessary to invent a modular lamp pole that reduces production costs, can be spliced, is easy to transport, streamlines production materials, is simple to process and has good stability. Utility Model Content

[0004] Purpose of the utility model: The present application is to solve the technical defects in the above-mentioned background technology and propose a lamp pole.

[0005] Technical solution: A lamp pole comprises an outer pole and an inner pole installed on the outer pole, wherein the bottom end of the inner pole is inserted into the outer pole and fixed to the inner wall of the outer pole through a connecting assembly.

[0006] Preferably, the connection assembly includes an upper sealing plate, a lower sealing plate, and a plurality of reinforcing ribs connected between the upper sealing plate and the lower sealing plate.

[0007] Preferably, the upper sealing plate and the inner rod and the outer rod are all fixedly connected, and the lower sealing plate and the inner rod and the outer rod are all fixedly connected.

[0008] Preferably, the upper sealing plate, the inner rod and the outer rod are all welded and fixed, and the lower sealing plate, the inner rod and the outer rod are all welded and fixed.

[0009] Each structure is fixed by welding, so that the overall structure has high strength and good stability.

[0010] Preferably, the reinforcing ribs and the inner rod and the outer rod are all fixedly connected.

[0011] Preferably, the reinforcing ribs, the inner rod and the outer rod are all fixed by welding.

[0012] The reinforcing ribs and the inner rod and the outer rod are fixed by welding, so that the connection has high strength and good stability.

[0013] Preferably, the upper sealing plate is a circular ring structure, the inner diameter of the upper sealing plate is the same as the outer diameter of the inner rod, and the outer diameter of the upper sealing plate is the same as the inner diameter of the outer rod.

[0014] Preferably, the lower sealing plate is a circular ring structure, the outer diameter of the lower sealing plate is the same as the inner diameter of the outer rod, and the inner diameter of the lower sealing plate is smaller than the outer diameter of the inner rod.

[0015] The inner diameter of the lower sealing plate is smaller than the outer diameter of the inner rod, so that the lower sealing plate can also play a supporting role for the inner rod.

[0016] Preferably, the number of the reinforcing ribs is 4-8, and the plurality of reinforcing ribs are distributed in a circular shape with equal intervals.

[0017] Multiple reinforcing ribs are distributed in a circular shape with equal spacing, so that the fixation is more uniform and the stability is good.

[0018] Preferably, the upper surface of the upper sealing plate is flush with the top surface of the outer rod.

[0019] The upper sealing plate is flush with the top surface of the outer rod, so that the overall appearance of the lamp pole is good.

[0020] Preferably, the length of the inner rod inserted into the outer rod portion is greater than 15 cm.

[0021] If the portion of the inner rod inserted into the outer rod is too short, the reinforcing rib will not be able to fix the inner rod effectively.

[0022] Preferably, the distance from the upper surface of the lower sealing plate to the upper surface of the upper sealing plate is greater than 15 cm.

[0023] In some embodiments, welding holes are opened at the upper sealing plate, and the welding holes are circular or elongated. The number and positions of the welding holes correspond to the number and positions of the reinforcing ribs.

[0024] When the lower sealing plate and the reinforcing ribs are welded first and then the upper sealing plate is welded, the position of the upper sealing plate will block the reinforcing ribs, making it impossible to weld the upper sealing plate and the reinforcing ribs. At this time, it is necessary to open welding holes on the upper sealing plate at the corresponding positions of each reinforcing rib, weld and fix the upper sealing plate and the reinforcing ribs through the welding holes, and finally grind off the weld scars.

[0025] In other embodiments, welding holes are provided at the lower sealing plate, and the welding holes are circular or elongated. The number and positions of the welding holes correspond to the number and positions of the reinforcing ribs. An installation hole is provided at the outer rod, and the installation hole is located below the lower sealing plate.

[0026] When a mounting hole for installing equipment is opened at the outer rod and below the lower sealing plate, such as installing a broadcast, an emergency alarm device or an electrical compartment of a street lamp, the staff can perform welding work through the mounting hole. This avoids opening welding holes at the upper sealing plate. First, weld the upper sealing plate and the reinforcement ribs, and finally weld the lower sealing plate. Similarly, welding holes are opened at the lower sealing plate for welding. This welding method can make the installation of the upper sealing plate more secure and the appearance of the upper sealing plate can be kept intact.

[0027] Beneficial effects: The outer rod and the inner rod of the present application adopt a split design, and are installed and fixed by connecting components at the installation site, so that the appropriate inner rod and outer rod can be selected according to the installation requirements on site, and then installed with connecting components of corresponding sizes, thereby realizing modular installation; the present application fixes the inner rod through plug-in and welding, and the inner diameter of the lower sealing plate is smaller than the outer diameter of the inner rod, which can play a supporting role, so the installation stability of the inner rod is good, which is convenient for the subsequent socketing on the inner rod or installing some external equipment through the clamp.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1-3 As shown: a lamp pole, comprising an outer pole 1 and an inner pole 2 installed on the outer pole 1, wherein the bottom end of the inner pole 2 is inserted into the outer pole 1 and fixed to the inner wall of the outer pole 1 through a connecting assembly.

[0036] The connecting assembly includes an upper sealing plate 3, a lower sealing plate 4 and a plurality of reinforcing ribs 5 connected between the upper sealing plate 3 and the lower sealing plate 4; the upper sealing plate 3 and the inner rod 2 and the outer rod 1 are fixedly connected, and the lower sealing plate 4 and the inner rod 2 and the outer rod 1 are fixedly connected; the upper sealing plate 3 and the inner rod 2 and the outer rod 1 are welded and fixed, and the lower sealing plate 4 and the inner rod 2 and the outer rod 1 are welded and fixed; the reinforcing ribs 5 and the inner rod 2 and the outer rod 1 are fixedly connected; the reinforcing ribs 5 and the inner rod 2 and the outer rod 1 are welded and fixed; the upper sealing plate 3 is a circular ring The structure is as follows: the inner diameter of the upper sealing plate 3 is the same as the outer diameter of the inner rod 2, and the outer diameter of the upper sealing plate 3 is the same as the inner diameter of the outer rod 1; the lower sealing plate 4 is a circular ring structure, the outer diameter of the lower sealing plate 4 is the same as the inner diameter of the outer rod 1, and the inner diameter of the lower sealing plate 4 is smaller than the outer diameter of the inner rod 2; the number of the reinforcing ribs 5 is 4-8, and the plurality of the reinforcing ribs 5 are distributed in a circular shape with equal spacing; the upper surface of the upper sealing plate 3 is flush with the top surface of the outer rod 1; the length of the inner rod 2 inserted into the outer rod 1 is greater than 15 cm; the distance from the upper surface of the lower sealing plate 4 to the upper surface of the upper sealing plate 3 is greater than 15 cm.

[0037] The upper sealing plate 3 is provided with welding holes 6 , which are circular or strip-shaped. The number and positions of the welding holes 6 correspond to the number and positions of the reinforcing ribs 5 .

[0038] Example 2

[0039] like Figure 4 As shown: The difference between this embodiment and embodiment 1 is that the welding hole 6 is opened at the lower sealing plate 4, the welding hole 6 is circular or elongated, the number and position of the welding holes 6 correspond to the reinforcing rib 5, and a mounting hole is opened at the outer rod 1, and the mounting hole is located below the lower sealing plate 4.

[0040] Working principle: After the inner rod and outer rod are selected, the matching upper and lower sealing plates are selected. Since the inner diameter of the lower sealing plate is smaller than the outer diameter of the inner rod, the outer rod will be supported by the lower sealing plate, and the length of the inner rod extending into the outer rod needs to be long enough to ensure the strength. Here, the length of the inner rod extending into the outer rod is at least 15cm. Preferably, we generally use 20cm. The staff will place the lower sealing plate 20cm away from the top surface of the outer rod, and weld it to the inner wall of the inner rod, and then weld the reinforcing ribs one by one to the top wall of the lower sealing plate, and then weld the reinforcing ribs to the inner wall of the lamp pole, and then put the upper sealing plate first. Put it on the inner rod, insert the inner rod between the reinforcement ribs inside the outer rod, weld the inner rod to the reinforcement ribs and the lower sealing plate, and finally weld the upper sealing plate to the reinforcement ribs, the outer wall of the inner rod and the inner wall of the outer rod (the upper sealing plate and the reinforcement ribs are welded through the welding holes opened on the upper sealing plate, and the weld scars are smoothed after welding). After welding, the upper sealing plate is flush with the upper surface of the outer rod, so that the overall appearance is good. The upper sealing plate can also prevent external liquid from flowing into the outer rod. At the same time, since some equipment will be installed on the inner rod in the later stage, the upper sealing plate can also support the equipment.

[0041] When a mounting hole for installing equipment is opened at the outer rod and below the lower covering plate, such as installing a broadcast, an emergency alarm device or an electrical compartment of a street lamp, welding can be performed through the mounting hole. This avoids opening a welding hole at the upper covering plate. Specifically, the upper covering plate is first welded to the top of the outer rod, and then the reinforcing ribs are welded to the upper covering plate and the inner wall of the outer rod. The inner rod is then inserted, and the inner rod is welded to the upper covering plate and the reinforcing ribs. Finally, the lower covering plate is welded to the inner wall of the outer rod and the inner rod. At this time, the lower covering plate and the reinforcing ribs are welded and fixed through the welding holes opened on the lower covering plate. This welding method can make the installation of the upper covering plate more secure and the appearance of the upper covering plate can be kept intact.

[0042] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
