Description

Technical Field

[0001] The invention relates to the technical field of solar street lamps, in particular to a street lamp cantilever arm. Background Art

[0002] As people's environmental awareness increases, solar street lights have gradually replaced ordinary lighting street lights. Existing solar street lights generally include a column, an arm mounted on the column, a lamp holder mounted at one end of the arm, and a solar panel mounted at the other end of the arm or on the column. Existing street light arms are generally vertically integrated with the column. This structure is inconvenient to transport. For this reason, some people connect the column and the street light arm by bolts to facilitate transportation. However, when used in some windy areas, the bolts are easy to loosen after a long time of use, resulting in a loose connection, which in turn damages the street light arm. Once the street light arm is damaged, the lamp holder fixed on it falls to the ground from a high altitude and is easily damaged. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a street lamp cantilever arm to solve at least one of the above-mentioned technical problems.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] Example 1, please refer to Figure 1The present embodiment is a street lamp cantilever arm, comprising a transverse tube 1 and a vertical tube 2. An extension portion 1-1 extending outward is provided at one end of the transverse tube, and the extension portion is fixed to the vertical tube by a bolt 3. During manufacture, a hole for the bolt to pass through can be provided on the extension portion, and a threaded hole can be provided on the vertical tube, and the bolt passing hole can be connected with the threaded hole; a baffle 4 is provided in the transverse tube, and the baffle is connected to the inner wall of the transverse tube, and generally can be connected by welding or an integral setting; a strip elastic body 5 is fixed on the baffle, and the end of the strip elastic body not connected to the baffle is connected to the vertical tube The strip elastic body can be an elastic band, an elastic rope or a spring, the elastic band can be a rubber band or a silicone band, and the elastic rope can be a rubber rope or a silicone rope; a support arm 6 is provided on the vertical tube, wherein the support arm can be detachably connected or welded to the vertical tube; the support arm is connected to the horizontal tube, and the connection position can be located on the bottom surface, the side surface or around the horizontal tube. It can be selected according to actual conditions. Generally, a clamp or other structure can be used to connect to the horizontal tube, or other detachable connection methods can be used. The connection position between the support arm and the horizontal tube forms a support portion, and the baffle is located on the side of the support portion facing away from the vertical tube.

[0016] The above-mentioned street lamp cantilever arm has the following advantages: 1. The strip elastic body cooperates with the baffle to generate elastic tension inside the cross tube, thereby preventing the bolts from loosening when the cross tube is affected by wind force or other effects; 2. The horizontal pipe, vertical pipe and supporting part support each other, making the whole structure more solid; 3. When the wind is strong, the horizontal tube is not easy to deform at the support part, so it will be subjected to greater force at the support part. Therefore, even if it is damaged, it will be damaged at the support part. Once damaged, the strip elastic body cooperates with the baffle to elastically connect the part of the horizontal tube connecting the lamp head with the vertical tube, which can buffer the impact of wind on the lamp head, making it difficult for the lamp head to fall to the ground from a high place and be damaged.

[0017] As an implementation method, see Figure 2 A center hole 4-1 is provided in the middle of the baffle, and a blocking head 5-1 is provided at one end of the strip elastic body. The diameter of the blocking head is larger than the diameter of the center hole, and the other end of the strip elastic body passes through the center hole and is fixed on the vertical pipe; wherein, the blocking head can be a lump formed by fastening one end of the strip elastic body, or it can be a ring, a sphere or a disc with an annular connecting part, etc. When in use, the strip elastic body is mounted on the annular structure, which is not specifically limited here.

[0018] As an embodiment, the vertical tube is provided with a through hole 2-1 for the strip elastic body to pass through, and the strip elastic body is fixed in the vertical tube through the through hole. In order to facilitate the installation of the lamp holder connecting wire, a plurality of side holes 4-2 can also be arranged on the baffle in the circumferential direction with the center hole as a reference.

[0019] Example 2, please refer to Figure 3 The present embodiment is a street lamp cantilever arm, comprising a transverse tube 1 and a vertical tube 2, wherein an extension portion 1-1 extending outward is provided at one end of the transverse tube, and the extension portion is fixed to the vertical tube by a bolt 3. During manufacture, a hole for the bolt to pass through can be provided on the extension portion, and a threaded hole can be provided on the vertical tube, and the bolt passing hole can be connected with the threaded hole; a baffle 4 is provided in the transverse tube, and the baffle is connected to the inner wall of the transverse tube, and can generally be connected by welding or an integral setting; a strip elastic body 5 is fixed on the baffle, and the end of the strip elastic body not connected to the baffle is connected to the vertical tube, wherein the strip elastic body can be an elastic band, an elastic rope or a spring, the elastic band can be a rubber band or a silicone band, and the elastic rope can be a rubber rope or a silicone rope; a groove 7 is provided on the transverse tube in the circumferential direction, and the baffle is located on the side of the groove facing away from the vertical tube.

[0020] The above-mentioned street lamp cantilever arm has the following advantages: 1. The strip elastic body cooperates with the baffle to generate elastic tension inside the cross tube, thereby preventing the bolts from loosening when the cross tube is affected by wind force or other effects; 2. Simple structure, easier to make and transport; 3. When the wind is strong, the groove is easy to deform, so the horizontal tube is easy to be damaged in the groove. When the horizontal tube is damaged, the strip elastic body cooperates with the baffle to elastically connect the part of the horizontal tube connecting the lamp holder with the vertical tube, which can buffer the impact of wind on the lamp holder, making it difficult for the lamp holder to fall to the ground and be damaged.
