Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically to a lamp that can be installed, disassembled, and maintained without tools. Background Technology

[0002] Some high-power lighting fixtures require regular maintenance after being put into use. When maintaining these fixtures, since they are usually installed at high altitudes, maintenance personnel need to operate from a height, which presents certain operational challenges and safety risks. The connection between the lighting fixture and the pole, the connection of the fixture's components, and the location of the components within the fixture's housing all play a decisive role in the difficulty of the maintenance work. To reduce the difficulty of maintaining lighting fixtures, some lighting fixtures have been designed to facilitate maintenance. For example, Chinese utility model patent CN117781202B discloses a modularly maintainable LED lighting fixture structure. This fixture reduces the number of components in the main body of the lamp housing by setting components in a rotatable flip-out section within the lamp housing. It also exposes the components connected to the rotatable flip-out section, while providing sufficient space for maintenance personnel to perform maintenance. However, the two rotatable flip-out sections of the lamp housing are not secured after flipping out. The rotatable flip-out section at the front of the lamp housing tends to tilt backward, causing damage to the rotatable flip-out section at the rear of the lamp housing and the components connected to it.

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] like Figures 1 to 8 As shown, a tool-free lamp assembly and maintenance includes a lamp housing 1 having a front cover 2, a rear cover 3, a front chamber 11, and a rear chamber 12. A light source assembly 16 is disposed in the front chamber 11, and a power supply assembly 17 is disposed in the rear chamber 12. A sensor 14 is disposed on the surface of the lamp housing 1 outside the rear chamber 12. A heat dissipation groove 18 is disposed on the surface of the lamp housing 1 outside the front chamber 11. A light-transmitting plate 15 is disposed on the outer side of the light source assembly 16. A connection structure is provided between the lamp housing 1 and the front cover 2 and the rear cover 3, and the connection structure includes: Rotating component 4; disposed between the front chamber 11 and the rear chamber 12 of the lamp housing 1, and the opposite ends of the front cover 2 and the rear cover 3 are both hinged to the rotating component 4, thereby realizing that one end of the front cover 2 can be rotated and opened with the rotating component 4 as the rotation center, and one end of the rear cover 3 can be rotated and opened with the rotating component 4 as the rotation center. The buckle assembly 5 consists of two sets, which are set at the positions where the outer surface of the lamp housing 1 joins the front cover 2 and the rear cover 3, respectively, to fasten and fix the lamp housing 1 to the front cover 2 and the lamp housing 1 to the rear cover 3.

[0023] A shaft-type connector; disposed at the rear of the lamp housing 1 and fixedly connected to the lamp housing 1, including a first shaft-type connector 6 connected to the housing and a second shaft-type connector 7 hinged to the second shaft-type connector 7; It should be noted that the lamp and the lamp post are connected by the shaft connector. When the lamp needs to be inspected and maintained, the lamp is first rotated by adjusting the shaft connector to make the lamp as a whole horizontal. Then, after manually releasing the buckle assembly 5, the front cover 2 or the rear cover 3 can be rotated and opened by the rotating assembly 4 to expose the front chamber 11 and the rear chamber 12 inside the lamp. Maintenance personnel can directly inspect and maintain the light source assembly 16 in the front chamber 11 or the power supply assembly 17 in the rear chamber 12. It should be noted that the front cover 2 and the rear cover 3 are each individually secured to the lamp housing 1 with a snap-fit ​​assembly 5. During maintenance, personnel can selectively open either the front cover 2 or the rear cover 3 to address the damaged area of ​​the power supply assembly 17 or the light source assembly 16, without simultaneously disassembling both covers, thus improving maintenance efficiency. Furthermore, the snap-fit ​​assembly 5 eliminates the need for tools during installation and removal, further simplifying the process and reducing maintenance difficulty. This design not only enhances the practicality and convenience of the lamp but also helps reduce maintenance costs and time.

[0024] It should be noted that when adjusting the lamp to a horizontal position using the shaft connector, the maintenance personnel need to loosen the locking member 8 and then rotate the first shaft connector 6 by applying a certain steering force to disengage the first tooth surface and the second tooth surface. After adjusting to a suitable angle, the locking member is then tightened to fix the first shaft connector 6 and the second shaft connector 7.

[0025] It should be noted that when the lamp is adjusted to a horizontal placement angle via the shaft connector, the front cover 2 and the rear cover 3 on the lamp housing 1 are both facing downwards. After the buckle assembly 5 is released from the connection with the front cover 2 or the rear cover 3, the front cover 2 and the rear cover 3 are opened and remain open under their own weight. There is no need to apply additional fixing structures after the front cover 2 and the rear cover 3 are opened to prevent them from tipping over or affecting the maintenance personnel's operation.

[0026] In the technical solution of the rotating component 4 of this utility model, the rotating component 4 includes a rotating base 41 integrally formed with the lamp housing 1, and a rotating shaft 42 passing through the outer side of the rotating base 41 to the inner side of the rotating base 41. The principle is that the rotating shaft 42 is passed through the front cover 2 and the rear cover 3, and the opposite ends of the front cover 2 and the rear cover 3 are hinged to the rotating shaft 42. Specifically, there are two rotating bases 41, including a first rotating base 41 and a second rotating base 41 on both sides of the width of the lamp housing 1. The opposing ends of the front cover 2 and the rear cover 3 are located between the first rotating base 41 and the second rotating base 41 and are both rotated and opened with the rotating shaft 42 as the rotation center. There are one or two rotating shafts 42. When there is one rotating shaft 42, the rotating shaft 42 passes horizontally through the first rotating base 41 and connects to the second rotating base 41, thereby achieving a hinge connection between the ends of the front cover 2 and the rear cover 3. When there are two rotating shafts 42, the rotating shafts 42 pass through the outer side of the first rotating base 41 and the outer side of the second rotating base 41, respectively, thereby achieving a hinge connection between the ends of the front cover 2 and the rear cover 3. Furthermore, in the above solution, the end of the front cover 2 facing the rear cover 3 is provided with a concave connecting portion 21, and the end of the rear cover 3 facing the front cover 2 is provided with a convex connecting portion 31, and the convex connecting portion 31 is axially aligned with the concave connecting portion 21. The outer side of the convex connecting part 31 is aligned with the inner side of the concave connecting part 21, and the end of the rotating shaft 42 passes horizontally through the concave connecting part 21 and the convex connecting part 31 in sequence.

[0027] In one technical solution, when there are two rotating shafts 42, one of the rotating shafts 42 passes through the outer side of the first rotating base 41 and the outer side of the second rotating base 41, and passes through the concave connecting part 21 and the convex connecting part 31 in sequence. The front cover 2 and the rear cover 3 rotate and open coaxially, which simplifies the flipping structure of the front cover 2 and the rear cover 3.

[0028] In the technical solution of the buckle assembly 5 of this utility model, buckle assemblies 5 are provided at the end of the front cover 2 away from the rear cover 3 and on both sides of the rear cover 3 away from the front cover 2. The buckle assembly 5 includes a buckle member 51, a torsion spring 52 and a buckle base 53. The torsion spring 52 is formed by bending a single metal column. The middle part of the torsion spring 52 is hinged to the buckle base 53. The two ends of the torsion spring 52 are hinged to the buckle member 51. The outer surface of the buckle member 51 is flush with the outer surface of the lamp housing 1 in the buckled state.

[0029] Furthermore, in the above solution, one end of the buckle 51 is bent to form a hook-shaped fastening part 511, which is used to fasten the front cover 2 or the rear cover 3 onto the lamp housing 1. The other end of the buckle 51 is provided with a connecting part 512 that is hinged to the torsion spring 52. It should be noted that the buckle base 53 is fixedly disposed on the outer side of the front cover 2 or the rear cover 3, thereby locking the front cover 2 or the rear cover 3 using the buckle assembly 5. The buckle member 51 is provided with a connecting part 512 for hinged connection between the torsion spring 52 and the buckle member 51. In the buckled state, the outer surface of the buckle member 51 is flush with the outer surface of the lamp housing 1, which is not only aesthetically pleasing but also prevents the buckle member 51 from being damaged by accidental collision. When it is necessary to open the front cover 2 or the rear cover 3, simply pry open the buckle member 51 and rotate the buckle member 51 around the torsion spring 52 to unlock it, thereby facilitating the opening of the front cover 2 or the rear cover 3.

[0030] In the technical solution of the shaft connector of this utility model, the first shaft connector 6 includes a first square base 61 that is fixed to the housing by screws and a first cylindrical base 62 that is hinged to the second shaft connector 7; the second shaft connector 7 includes a second cylindrical base 72 that is aligned with the axis of the first cylindrical base 62 and a second square base 71 that is connected to the lamp post.

[0031] Furthermore, in the above scheme, the end face of the first cylindrical base 62 facing the second cylindrical base 72 is provided with a first tooth surface 63, and the end face of the second cylindrical base 72 facing the first cylindrical base 62 is provided with a second tooth surface 73, and the first tooth surface 63 and the second tooth surface 73 are adapted in shape.

[0032] In the technical solution of this utility model for a lamp, the light source assembly 16 and the power supply assembly 17 are respectively disposed in the front chamber 11 and the rear chamber 12 of the lamp housing 1. Maintenance personnel can directly open the front cover 2 or the rear cover 3 for repair according to the damaged location of the lamp. Maintenance personnel can manually pry open the buckle assembly 5 to open the front cover 2 and the rear cover 3 without tools, which facilitates maintenance personnel to maintain the lamp components in the front chamber 11 and the rear chamber 12.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
