[0033] A shed pole lamp is a kind of lamp installed on the top of a pole or a shed, and is applicable to high or wide places such as factories, power plants, steel mills, workshops, warehouses, gymnasiums, waiting rooms, stations, gas stations, airports, shopping malls, etc. It has a wide application range and has the advantages of long service life, high brightness, waterproof, concentrated light beam, etc.

[0034] The existing shed pole lamp is installed on a pole, and has an opening in the middle thereof. When installing, the end of the pole passes through the opening to install the shed pole lamp. However, this installation method makes the shed pole lamp need to be adapted to a pole with a certain diameter. When the pole is thicker, the volume of the shed pole lamp needs to be processed larger, which is not convenient for transportation and storage. The scheme of dividing the shed pole lamp into two independent parts to clamp the pole can adapt to poles with a larger diameter, but on the one hand, it is difficult to achieve the interconnection of current for the two independent parts, and two power supply components need to be configured for power supply; on the other hand, it is extremely inconvenient during installation.

[0035] The applicant found that in some existing fruit and vegetable sheds, there are metal support poles for support in the middle of the shed, so the shed pole lamp can be installed using this metal pole. However, all the existing shed pole lamps need to be installed from the end of the pole. See Figure 1, in the existing canopy pole lamp, there is an opening 10 in the middle of the pole, and the end of the pole passes through this opening 10 to achieve the installation of the canopy pole lamp. The existing canopy pole lamp cannot utilize the existing support poles of the fruit and vegetable shed (the end of the support pole is connected to the canopy and cannot pass through the opening 10 of the existing canopy pole lamp).

[0036] The applicant further thought that the canopy pole lamp could be split into two independent bodies, and the two bodies clamp the metal support pole, thus making good use of the metal pole without the need to additionally increase the pole. However, there are the following problems after splitting the canopy pole lamp into two bodies. On the one hand, the installation of the two independent bodies is rather troublesome, and it is necessary to align the two bodies and then carry out threaded assembly. On the other hand, it is difficult for the two independent bodies to conduct effective current interconnection, and it is necessary to respectively arrange power supply components in the two bodies, resulting in a relatively high cost.

[0037] In view of this, referring to Figures 2 - 6 , the present application provides a rotating assembly 100 of a canopy pole lamp. The canopy pole lamp 100 is used for installation on a metal pole and includes a first body, a second body, and a power supply component.

[0038] The first body includes a first housing 110 and a first lamp group arranged in the first housing 110. The first housing 110 includes a first inner arc wall 111. The second body includes a second housing 120 and a second lamp group arranged in the second housing 120. The second housing 120 includes a second inner arc wall 112 opposite to the first inner arc wall 111. The first inner arc wall 111 and the second inner arc wall 112 jointly clamp the metal pole. The second housing 120 is hinged to the first housing 110 (the first housing 110 and the second housing 120 can be directly hinged or indirectly hinged by using other intermediate elements), so that the first housing 110 can rotate relative to the second housing 120 around the metal pole. In the present application, by rotating the first housing 110 relative to the second housing 120, on the one hand, the space between the first inner arc wall 111 and the second inner arc wall 112 can be adjusted, so as to adapt to metal poles of different diameters. On the other hand, the first body and the second body are hinged together, and the installation is very convenient.

[0039] The power supply component is arranged in the first housing 110. The power supply component is used for obtaining electric energy and supplying power to the first lamp group and the second lamp group. The power supply component can directly supply power to the first lamp group in the first housing 110.

[0040] In particular, a first power supply contact 151 is provided on the outer wall surface of the first inner arc wall 111. The first power supply contact 151 is electrically connected to a power supply component. A second power supply contact 152 is provided on the outer wall surface of the second inner arc wall 112. The second power supply contact 152 is electrically connected to a second lamp group for obtaining current and supplying power to the second lamp group. The shed pole lamp 100 is configured such that after the first inner arc wall 111 and the second inner arc wall 112 clamp the metal rod, the first power supply contact 151 and the second power supply contact 152 are electrically connected through the metal rod. In other words, the power supply component can direct the current to the first power supply contact 151. When the shed pole lamp 100 is clamped to the metal rod, the first power supply contact 151 contacts the metal rod to direct the current to the metal rod, and the second power supply contact 152 contacts the metal rod so that the second power supply contact 152 can obtain current from the metal rod and then direct the current to the second lamp group. In this solution, there are no conductive components between the first body and the second body, but the metal rod is used for conduction, so as to realize the intercommunication of the current between the first body and the second body. Compared with the solution of arranging a wire at the hinge of the first housing 110 and the second housing 120 to electrically connect the power supply component and the second lamp group, there are fewer parts, the cost is low, and it is not easy to fail, and the maintenance cost is low (in the existing solution of arranging a wire at the hinge, the wire is easy to break after being used for a long time and bent multiple times).

[0041] In particular, for safety reasons, the power supply component can control the magnitude of the voltage directed to the second lamp group, and the voltage directed to the second lamp group is a safety voltage, that is, the voltage transmitted between the first power supply contact 151 and the second power supply contact 152 is less than 36V, specifically, it can be less than 30V.

[0042] In some embodiments, the first power supply contact 151 is connected to a first spring, and the first spring generates an elastic force that pushes the first power supply contact 151 towards the metal rod. The second power supply contact 152 is connected to a second spring, and the second spring generates an elastic force that pushes the second power supply contact 152 towards the metal rod. In this solution, after the first inner arc wall 111 and the second inner arc wall 112 clamp the metal rod, the first power supply contact 151 and the second power supply contact 152 can be in good contact with the metal rod, thus eliminating the problem that the second lamp group does not light up due to poor contact.

[0043] In some embodiments, the first housing 110 is indirectly hinged to the second housing 120. Specifically, the shed pole lamp 100 further includes a first arc-shaped plate 130. One end of the first arc-shaped plate 130 is hinged to one end of the first housing 110, and the other end of the first arc-shaped plate 130 passes through one end of the second housing 120 and is located inside the second housing 120. The first arc-shaped plate 130 is configured to be able to slide relative to the second housing 120, and the other end of the first arc-shaped plate 130 is configured to be restricted inside the second housing 120 (that is, the first arc-shaped plate 130 cannot completely extend out of the second housing 120). Such a structure can adapt to a metal pole with a larger diameter. When the diameter of the metal pole is relatively large, the first housing 110 and the second housing 120 can be arranged in exactly opposite positions to provide a maximized lighting range. When the diameter of the metal pole is relatively small, the part of the first arc-shaped plate 130 extending into the second housing 120 is relatively large. When the diameter of the metal pole is relatively large, the part of the first arc-shaped plate 130 extending out of the second housing 120 is relatively large, so that the first inner arc wall 111, the second inner arc wall 112, and the first arc-shaped plate 130 jointly clamp the metal pole.

[0044] In some embodiments, in order to facilitate clamping of the metal pole, a torsion spring is connected between the first arc-shaped plate 130 and the first housing 110. The torsion spring is configured to generate an elastic force that causes the first housing 110 and the first arc-shaped plate 130 to rotate in a direction close to the metal pole.

[0045] In some embodiments, a first engaging member is provided at one end of the first housing 110 facing away from the first arc-shaped plate 130, and a second engaging member 141 is provided at one end of the second housing 120 facing away from the first arc-shaped plate 130. The first engaging member is used for engaging connection with the second engaging member 141. This solution can facilitate the quick disassembly and assembly of shed poles and the like.

[0046] In some embodiments, a first engaging member is provided at one end of the first housing 110 facing away from the first arc-shaped plate 130. The shed pole lamp 100 further includes a second arc-shaped plate 140. One end of the second arc-shaped plate 140 is inserted into the second housing 120, and a second engaging member 141 is provided at the other end of the second arc-shaped plate 140. The second engaging member 141 is configured to be engaged and connected with the first engaging member, and the second arc-shaped plate 140 is configured to be slidable relative to the second housing 120. Such a structure can further adapt to a metal pole with a larger diameter. When the diameter of the metal pole is relatively large, the first housing 110 and the second housing 120 can be arranged in exactly opposite positions to provide a maximized illumination range. When the diameter of the metal pole is relatively small, a relatively large portion of the first arc-shaped plate 130 extends into the second housing 120, and a relatively large portion of the second arc-shaped plate 140 extends into the second housing 120. When the diameter of the metal pole is relatively large, a relatively large portion of the first arc-shaped plate 130 extends out of the second housing 120, and a relatively large portion of the second arc-shaped plate 140 extends out of the second housing 120, so that the first inner arc wall 111, the second inner arc wall 112, the first arc-shaped plate 130, and the second arc-shaped plate 140 jointly clamp the metal pole.

[0047] In some embodiments, the first housing 110 further includes a first outer arc wall 112, and the second housing 120 further includes a second outer arc wall 122. One end of the first arc-shaped plate 130 facing away from the first housing 110 is attached to the second outer arc wall 122. This solution can facilitate the sliding of the first arc-shaped plate 130.

[0048] See Figures 3 - 5, in some embodiments, a first rack is provided on the wall surface of the first arc-shaped plate 130 facing away from the second outer arc wall 122. The second arc-shaped plate 140 is disposed on the side of the first arc-shaped plate 130 facing away from the second outer arc wall 122. A second rack is provided on the wall surface of the second arc-shaped plate 140 facing the first arc-shaped plate 130. The shed pole lamp 100 further includes a rotating shaft 160. The rotating shaft 160 is disposed through the second housing 120 along a direction parallel to the metal rod. A part of the rotating shaft 160 is located outside the second housing 120, and another part is located inside the second housing 120, and it can rotate around an axis parallel to the metal rod. A gear 161 is provided at the end of the rotating shaft 160 located inside the second housing 120. The gear 161 is disposed between the first arc-shaped plate 130 and the second arc-shaped plate 140, and the gear 161 meshes with the first rack and the second rack respectively. Wherein, when the rotating shaft 160 rotates in the first direction, the first arc-shaped plate 130 slides towards the inside of the second housing 120, and the second arc-shaped plate 140 slides towards the inside of the second housing 120; when the rotating shaft 160 rotates in the second direction opposite to the first direction, the first arc-shaped plate 130 slides towards the outside of the second housing 120, and the second arc-shaped plate 140 slides towards the outside of the second housing 120. In this solution, by rotating the rotating shaft 160, the extending lengths of the first arc-shaped plate 130 and the second arc-shaped plate 140 can be adjusted simultaneously, which is more convenient for adjustment.

[0049] In some embodiments, a third engaging member is provided on the outer wall surface of the second housing 120. A fourth engaging member is provided on the wall surface of the part of the rotating shaft 160 located outside the second housing 120 facing the third engaging member. The rotating shaft 160 is configured to be able to slide relative to the second housing 120 along a direction parallel to the metal rod, and when the rotating shaft 160 slides to make the third engaging member and the fourth engaging member engage and connect, it cannot rotate relative to the second housing 120, and when it rotates and slides to make the third engaging member and the fourth engaging member separate, it can rotate relative to the second housing 120. In this solution, during the installation process of the shed pole lamp 100, the rotating shaft 160 slides along a direction parallel to the metal rod to make the third engaging member and the fourth engaging member separate, and then rotates around an axis parallel to the metal rod to adjust the lengths of the first arc-shaped plate 130 and the second arc-shaped plate 140 extending into the second housing 120. When the length adjustment is in place, the rotating shaft 160 is pushed to slide along a direction parallel to the metal rod to make the third engaging member and the fourth engaging member engage, so as to lock the extending lengths of the first arc-shaped plate 130 and the second arc-shaped plate 140. The rotating shaft 160 can also provide a clamping force of the shed pole lamp 100 on the metal rod. Both the third engaging member and the fourth engaging member can be annular racks, and they engage with each other to achieve engagement.

[0050] To achieve the above functions, the parts of the first arc-shaped plate 130 and the second arc-shaped rod except for the first rack and the second rack can be made of flexible plastic (the first rack and the second rack are made of metal materials), and a first guide groove 123 is provided inside the second housing 120. The first arc-shaped plate 130 is embedded in the first guide groove 123 and configured to be able to slide inside the first guide groove 123. A second guide groove 124 is also provided inside the second housing 120. The second arc-shaped plate 140 is embedded in the second guide groove 124 and configured to be able to slide inside the second guide groove 124. When the first arc-shaped plate 130 slides in the first guide groove 123, it produces a small deformation. When the second arc-shaped plate 140 slides in the second guide groove 124, it produces a small deformation.

[0051] The installation process of the shed pole lamp is as follows: Separate the first engaging part from the second engaging part 141, drive the first arc-shaped plate 130 to rotate relative to the first housing 110, so that the first housing 110 and the second housing 120 rotate relative to each other, and then the space between the first inner arc wall 111 and the second inner arc wall 112 becomes larger. Drive the rotating shaft 160 to rotate, and adjust the extending lengths of the first arc-shaped plate 130 and the second arc-shaped plate 140 so that after the first housing 110 and the second housing 120 clamp the metal rod, the first housing 110 and the second housing 120 are arranged on opposite sides of the metal rod. Make the first inner arc wall 111, the second inner arc wall 112, the first arc-shaped plate 130 and the second arc-shaped plate 140 jointly clamp the metal rod, and make the first engaging part and the second engaging part 141 engage. Rotate the rotating shaft 160 so that the first arc-shaped plate 130 and the second arc-shaped plate 140 slightly extend into the second housing 120, thereby increasing the pressure of the shed pole lamp 100 on the metal rod. Push the rotating shaft 160 to slide until the third engaging part and the fourth engaging part engage, thereby completing the final installation of the shed pole lamp 100.
