[0042] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in detail below in combination with the drawings and specific embodiments.

[0043] Here, it needs to be explained that, in order to avoid the utility model from being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the utility model are shown in the drawings, and other details not closely related to the utility model are omitted.

[0044] In addition, it also needs to be explained that the term "comprises", "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0045] Please refer to Figures 1 to 9 The utility model discloses a lamp pole (not shown in the drawing) including the main rod subassembly (not shown in the drawing) and the detachable installation in the main rod subassembly's vice rod subassembly 100. Wherein, the bottom of vice rod subassembly 100 is equipped with fixed seat 2, in this embodiment, fixed seat 2 is flange. Vice rod subassembly 100 is fixed in the top end of main rod subassembly through fixed seat 2.

[0046] Please refer to Figures 1 to 3 As shown in the figure, vice rod subassembly 100 includes vice rod body 1, the plurality of guide rails 3 fixed on the outer wall of vice rod body 1, the sliding block 4 slidingly connected in guide rail 3 and fixing piece 5. One end of fixing piece 5 is fixedly connected with sliding block 4, and the other end penetrates guide rail 3. In this embodiment, fixing piece 5 is screw or screw. In other embodiments, fixing piece 5 is a fastener with equivalent fixing function. Sliding block 4 is inserted from one end of guide rail 3, fixing piece 5 is threadedly connected with sliding block 4, and sliding block 4 is driven to rotate in guide rail 3 to be attached to the inner side wall 42 of guide rail 3 through fixing piece 5.

[0047] Vice rod body 1 is hollow cylindrical structure, and cold-drawing process is adopted. A plurality of grooves 11 can be formed on the outer wall of vice rod body 1 at one time through the cold-drawing process. Specifically, a plurality of grooves 11 matched with the plurality of guide rails 3 are arranged on the outer wall of vice rod body 1, and each groove 11 is recessed from the outer wall of vice rod body 1 to the center of vice rod body 1. The bottom surface of each guide rail 3 is attached to and fixed with the inner surface of groove 11, so that the contact area is increased, and the firmness and stability of the installation of guide rail 3 are improved. Each groove 11 is internally provided with a fixing wall 111 and guide walls 112 located on both sides of the fixing wall 111.

[0048] Please refer to Figure 4As shown, the plurality of guide rails 3 are fixedly connected to the top surface of the fixed seat 2. The fixed seat 2 serves as a support structure and can effectively bear the weight of the guide rails 3. In this embodiment, each guide rail 3 has the same structure, which will not be repeated here. The guide rail 3 includes a first arm 31 and a second arm 32 and a third arm 33 connected to the two ends of the first arm 31, respectively. The first arm 31 is in contact with and fixed to the inner surface of the groove 11. The second arm 32 and the third arm 33 are in contact with the two guide walls 112, respectively. The multiple contact points make the guide rail 3 and the groove 11 more closely combined, and can exhibit higher impact resistance when facing external force impact.

[0049] The end of the second arm 32 is provided with a first extension arm 321, and the end of the third arm 33 is provided with a second extension arm 331. The first extension arm 321 and the second extension arm 331 are both arranged in parallel with the first arm 31, and the included angle between the second arm 32 and the first extension arm 321 and the included angle between the third arm 33 and the second extension arm 331 are both acute angles.

[0050] The height direction is defined as the extension direction of the guide rail 3. The first arm 31 is fixedly connected to the outer wall of the secondary rod body 1. In this embodiment, the included angle between the first arm 31 and the second arm 32 is obtuse, and the included angle between the first arm 31 and the third arm 33 is also obtuse. Moreover, the included angle between the first arm 31 and the second arm 32 is equal to the included angle between the first arm 31 and the third arm 33. That is, in the projection direction perpendicular to the height direction, the cross section of the guide rail 3 is isosceles trapezoidal, which to some extent improves the ornamental value of the secondary rod assembly 100. In this way, the contact area between the slider 4 and the guide rail 3 can be increased, and the cooperation between the guide rail 3 and the slider 4 is more closely. The design of isosceles trapezoidal helps to optimize the stress distribution inside the guide rail 3. When subjected to external force, the stress can be more evenly distributed in each part of the guide rail 3, reducing the risk of structural damage caused by stress concentration.

[0051] In some embodiments, the included angle between the first arm 31 and the second arm 32 or the included angle between the first arm 31 and the third arm 33 is equal to 90°. That is, in the projection direction perpendicular to the height direction, the cross section of the guide rail 3 is a right trapezoid. In this way, the guide rail 3 can occupy a smaller space while providing sufficient support area.

[0052] In other embodiments, the included angle between the first arm 31 and the second arm 32 and the included angle between the first arm 31 and the third arm 33 are both greater than 90°, and they are not equal. The cross section of the guide rail 3 is a non-isosceles trapezoid. This design can provide stronger support and stability in a specific direction according to actual needs. For example, in areas with strong winds, the contact area between the guide rail 3 and the slider 4 / groove 11 can be increased by adjusting the included angle, thereby enhancing the stability of the guide rail 3 in the wind direction and reducing the structural deformation or damage caused by wind force.

[0053] As shown in Figure 3 and Figure 5 , the slider 4 is movably arranged in the guide rail 3. The slider 4 comprises a first hole 41 and four side walls 42. The first hole 41 is fixed on the slider 4 for the fixing member 5 to pass through. Preferably, the first hole 41 is fixed at the center of the slider 4, which facilitates the driving of the slider 4 by the fixing member 5. The two oppositely arranged side walls 42 of the slider 4 are arranged in parallel, which helps to optimize the stress distribution inside the slider 4. When subjected to external force, the stress can be more evenly distributed in each part of the slider 4, reducing the risk of structural damage caused by stress concentration.

[0054] In this embodiment, two rotating surfaces 421 and two connecting surfaces 422 are arranged on each of the oppositely arranged side walls 42, and the connecting surfaces 422 are connected with the rotating surfaces 421. Moreover, the two connecting surfaces 422 are arranged in parallel with each other, and the two rotating surfaces 421 are also substantially parallel, so that the cross section of the slider 4 in the extension direction of the guide rail 3 is substantially a parallelogram. The slider 4 is adapted to the guide rail 3, which facilitates the replacement or adjustment of the position of the slider 4. The rotating surface 421 comprises an arc surface 4211 and an abutting surface 4212 connected with each other. The arc surface 4211 enables the slider 4 to rotate more smoothly in the guide rail 3. Specifically, the arc surface 4211 can guide the rotation of the slider 4, so that the user can more easily adjust the position and angle of the slider 4, and the installation and maintenance process of the slider 4 also becomes more convenient. At the same time, the design of the arc surface 4211 also reduces the wear caused by friction with the guide rail 3, thereby reducing the maintenance cost.

[0055] When the slider 4 is fixed in the guide rail 3, the abutting surfaces 4212 respectively abut the second arm 32 and the third arm 33 to increase the contact area between the guide rail 3 and the slider 4, thereby increasing the friction therebetween to enable the guide rail 3 and the slider 4 to be tightly connected.

[0056] As shown in Figures 6 to 7 , the slider 4 is vertically inserted into the guide rail 3, and the fixing member 5 is connected with the slider 4 by passing through the first hole 41, and the fixing member 5 drives the slider 4 to move to the target position. Then, the fixing member 5 drives the slider 4 to rotate, so that the arc surface 4211 abuts the second arm 32 of the guide rail 3, and the slider 4 is continuously rotated until the abutting surface 4212 abuts the second arm 32 of the guide rail 3. In this way, since the abutting surface 4212 completely abuts the second arm 32, the friction between the slider 4 and the guide rail 3 is increased, thereby enhancing the connection stability and tightness between the slider 4 and the guide rail 3.

[0057] Please refer to Figure 1 , Figure 8 and Figure 9As shown, the secondary rod assembly 100 further includes a bracket assembly 6, one end of which is detachably connected to the slider 4, and the other end of which is connected to the external expansion device 200. The bracket assembly 6 is provided with a second hole 61 corresponding to the first hole 41. The fixing member 5 passes through the second hole 61 and the first hole 41 in sequence to connect with the slider 4. The fixing member 5 drives the slider 4 to rotate, so that the rotating surface 421 of the slider 4 is in contact with the second arm 32, thereby achieving relative fixation between the slider 4 and the guide rail 3.

[0058] In this embodiment, the bracket assembly 6 includes a first bracket 62 and a second bracket 63. The first bracket 62 is used for forward installation, and the second bracket 63 is used for lateral installation. The first bracket 62 includes a mounting arm 621 fixedly connected to the slider 4 and fixed arms 622 arranged on both sides of the mounting arm 621. The fixed arms 622 abut against the groove 11, and the mounting arms 621 are parallel to the first arm 31. The mounting arm 621 is used to fixedly connect to the external expansion device 200, such as the camera device 2001. The camera is mounted on the camera mounting bracket, and the camera mounting bracket is fixed to the mounting arm 621. Similarly, the sound column can also be mounted on the first bracket 62.

[0059] The second bracket 63 includes a fixing frame 631 fixedly connected to the slider 4 and a mounting frame 632 arranged on the side of the fixing frame 631. The mounting frame 632 is used to install external expansion equipment 200, such as the antenna 2002 and the Internet of Things device 2003. The mounting frame 632 includes a first wall 6321 and a second wall 6322 arranged opposite each other, and a connecting wall 6323 connecting the first wall 6321 and the second wall 6322. The first wall 6321 is fixedly connected to the mounting frame 632. The end of the antenna 2002 is fixed to the connecting wall 6323. The Internet of Things device 2003 is installed on the second wall 6322 and is in contact with the second wall 6322.

[0060] In summary, the utility model cleverly arranges the first arm 31 and the second arm 32 on the guide rail 3, and makes the angle between the first arm 31 and the second arm 32 an obtuse angle. Thus, on the one hand, the contact area between the slider 4 and the guide rail 3 can be increased to increase the friction between the slider 4 and the guide rail 3, thereby ensuring the stability of the connection. On the other hand, the obtuse angle design also provides the slider 4 with ample room for movement, which is convenient for the user to install the slider 4 and subsequently adjust the position of the slider 4. Moreover, the obtuse angle design makes the contour lines of the guide rail 3 smoother, which improves the ornamental value of the sub-rod assembly 100 to a certain extent. In addition, by arranging the rotating surface 421 on the slider 4, the slider 4 can rotate within the guide rail 3, so that the rotating surface 421 fits the second arm 32, thereby increasing the contact area between the slider 4 and the guide rail 3, and making the slider 4 and the guide rail 3 tightly connected.

[0061] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
