It has an aesthetically pleasing appearance and can be folded to save space when not in use.
[0005] The aforementioned folding light poles have the following defects:
[0006] 1. After the light poles are extended, there is a certain angle between each light pole, making it impossible to achieve a completely vertical state, which affects the aesthetics of the equipment;
[0007] 2. The folding mechanism is achieved by using a linkage mechanism, but the folded space is relatively large and further optimization is needed.
[0008] Based on this, this application provides a novel folding structure for a folding lamp post that can be fully vertical when unfolded and save space when folded, in order to solve the above problems. Utility Model Content

[0034] Example 1
[0035] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides a novel folding structure for a folding lamp post, including a first lamp post 1, a second lamp post 2, a connecting support 3 with its two ends respectively hinged to the first lamp post and the second lamp post, and an electric push rod 4 hinged between the first lamp post and the connecting support, and between the second lamp post and the connecting support, respectively. The electric push rod is used to drive the folding or unfolding of the first lamp post and the second lamp post. Wherein:
[0036] The width and thickness of the first lamp post 1 and the second lamp post 2 are equal, and their lengths are determined according to the design.
[0037] As attached Figure 1 and attached Figure 3 As shown, the connecting support 3 includes a base plate 3.1, side plates 3.2 welded to both sides of the base plate, and front fixing brackets 3.3 welded to the outer top of the side plates respectively. The distance between the two base plates 3.1 is slightly greater than the width of the first lamp post 1 or the second lamp post 2. One end of the first lamp post and the second lamp post are respectively hinged to the groove-shaped space enclosed by the side plates 3.2 at both ends of the connecting support 3 via two symmetrically arranged first connecting shafts 5. In this embodiment, the first connecting shaft 5 is installed as follows: bushings 7 are welded to the holes on the side plates 3.2 for installing the first connecting shaft 5. The first connecting shaft 5 is inserted into the bushings 7, and both ends are fixed to the bushings 7 by locking bolts 8.
[0038] Preferred options are listed below. Figure 2 As shown, the distance L1 between the axis of the first connecting shaft 5 and the base plate 3.1 is equal to half the thickness L2 of the first lamp post 1 or the second lamp post 2. This design allows the first and second lamp posts to fit snugly against the base plate after being unfolded, thus providing a limiting effect. To ensure smooth rotation of the first and second lamp posts, there should be a gap between the ends of the first and second lamp posts 1 and 2 connected to the connecting support 3 and the base plate 3.1, and both ends should have rounded corners with the first connecting shaft 5 as the axis and L1 as the radius to prevent interference between the first and second lamp posts and the base plate during rotation.
[0039] Preferred options are listed below. Figure 2 and attached Figure 3 As shown, a grooved limiting plate 3.4 is welded between the two side plates 3.2 inside the connecting support 3. The grooved limiting plate 3.4 has limiting planes perpendicular to the bottom plate 3.1 on both sides, and the width L3 of the grooved limiting plate 3.4 is equal to the distance between the first lamp post 1 and the second lamp post 2 after they are horizontally folded. In this embodiment, the grooved limiting plate can, on the one hand, connect the two side plates and enhance the structural strength of the connecting support, and on the other hand, it can also play a limiting role after the first lamp post and the second lamp post are folded. The connecting support designed in this embodiment can realize the rotation of the first lamp post and the second lamp post between 0 and 90°.
[0040] As attached Figure 1 As shown, one end of each of the four electric push rods 4 is hinged to the sides of the first lamp post 1 and the second lamp post 2, and the other end is hinged to the groove-shaped space formed by the side plate 3.2 and the front fixed bracket 3.3 through the second connecting shaft 6.
[0041] Preferred options are listed below. Figure 3As shown, in this embodiment, the second connecting shaft 6 connecting the first lamp post 1 and the second lamp post 2 to the front fixed bracket 3.3 on both sides is a through shaft, which passes through the left and right sides of the front fixed bracket 3.3 of the connecting support 3. In this embodiment, the four electric push rods are installed by two coaxial shafts. Compared with the installation method of using four second connecting shafts, this can effectively improve the installation efficiency and better ensure the coaxiality of the two electric push rods on both sides of the first lamp post or the second lamp post.
[0042] Specifically, the installation method of the aforementioned through shaft is as follows: a bushing 7 is welded to the hole on the front fixed bracket 3.3 for installing the second connecting shaft 6. This structure is the same as the installation structure of the first connecting shaft on the side plate. The second connecting shaft 6 is inserted into the bushing 7, and both ends are fixed to the bushing 7 by locking bolts 8. In addition, a bushing 7 is also welded to the hole on the side plate 3.2 for installing the second connecting shaft 6, and a connecting sleeve 9 with both ends welded to the bushing 7 is provided between the two side plates 3.2 connected to the second connecting shaft 6. This connecting sleeve 9 can connect the two side plates and increase the structural strength of the connecting support.
[0043] The installation structure of the electric push rod 4 and the connecting support 3 is as follows: the push rod of the electric push rod 4 is equipped with a fisheye bearing 4.1, which is installed on the second connecting shaft 6 and located in the groove-shaped space formed by the side plate 3.2 and the front fixed bracket 3.2.
[0044] The installation structure of the electric push rod 4 with the first light pole 1 or the second light pole 2 is as follows: (see attached diagram) Figure 1 and attached Figure 4 As shown, both the first lamp post 1 and the second lamp post 2 are welded with a rear fixing bracket 10 for installing the electric push rod 4. The rear fixing bracket 10 includes a connecting plate 10.1, ear plates 10.2 welded to both sides of the connecting plate, and stiffening plates 10.3 welded to the inner side of the ear plates. The connecting plate 10.1 and stiffening plates 10.3 of the fixing bracket 10 are welded to the first lamp post 1 or the second lamp post 2.
[0045] In specific implementation, the folding structure of the first and second light poles is as shown in the attached figure. Figure 1 and attached Figure 2 As shown, when deployment is required, four electric push rods are extended, causing the first and second light poles to unfold outwards until they are fully extended as shown in the attached diagram. Figure 5 As shown, it can be fully vertically unfolded; when folding is needed, control the four electric push rods to retract, and the first and second light poles fold inwards until folded as shown in the attached diagram. Figure 1 Or attached Figure 2 As shown, it takes up little space when folded.
[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
