Description

Technical Field

[0001] This invention relates to the technical field of lighting fixtures, and more specifically to a tunnel lighting fixture that is easy to maintain. Background Technology

[0002] In outdoor settings such as tunnels, underpasses, and roads, lighting is often required along the route. The common installation method is as follows: first, the lamp holder is fixed on the tunnel or related supporting structure, and the power supply line is laid in advance; then, the workers mechanically assemble the lamp body and the lamp holder, while manually connecting the power supply line to the internal wiring of the lamp body to provide power.

[0003] This installation method has the following obvious drawbacks: First, low installation efficiency: The entire installation process involves multiple steps, including fixing the lamp holder, laying the wiring, assembling the lamp body, and connecting the wires. These steps rely on manual operation, which leads to long construction cycles and high labor costs, especially in environments such as tunnels where a large number of lamps are needed. Second, poor electrical connection reliability: The connection between the power supply line and the internal wiring of the lamp body depends on manual wiring on site. This can easily lead to loose wiring due to improper operation or inadequate tightening, or even missing or short-circuited connections, affecting the stable operation of the lighting system and posing safety risks. Third, inconvenient maintenance and replacement: When a lamp body malfunctions and needs to be replaced, maintenance personnel also need to perform a series of operations, such as disconnecting the wires, disassembling the lamp body and replacing it, and rewiring, which is a cumbersome process. Summary of the Invention

[0004] The purpose of this invention is to provide a tunnel lighting fixture that is easy to install and maintain, has good electrical connection reliability, and is easy to maintain.

[0005] To address the aforementioned problems, this invention provides a tunnel lighting fixture that is easy to maintain, comprising a lamp holder, a locking component, and a lamp body. The lamp holder has an upward-facing receiving groove into which the lamp body can be inserted. The inner sidewall of the receiving groove has an outwardly penetrating opening. The locking component is movably connected within the receiving groove and includes a latching portion and a push button portion facing the opening. The lamp holder has an elastic component acting on the locking component and a power supply contact facing the lamp body. The lamp body has pins corresponding to the power supply contacts and a limiting portion corresponding to the latching portion. When the lamp body is inserted into the receiving slot, the latching part is pushed by the elastic member and latched to the limiting part, and the push button part is pushed to the outside of the opening. At this time, the pin and the power supply contact abut against each other and conduction occurs. When the push button part is pushed to the inside of the opening, the locking member drives the latching part to disengage from the limiting part so that the lamp body can be removed from the receiving slot.

[0006] Compared with existing technologies, the above solution incorporates a locking mechanism inside the lamp holder. During installation, the lamp body is simply inserted into the receiving slot from top to bottom. The elastic element will then push the latching part to automatically engage with the limiting part of the lamp body, locking the lamp body within the receiving slot. Simultaneously, the lamp body's pins will directly contact and conduct with the power supply contacts, eliminating the need for manual wiring. This method is convenient, quick, and offers reliable electrical connections. When maintenance or replacement of the lamp body is required, simply push the push button inwards to disengage the locking mechanism from the limiting part, allowing the lamp body to be removed from the receiving slot. The operation is simple and convenient.

[0007] In an improved embodiment, the limiting part protrudes from the side wall of the lamp body, the latching part protrudes from the side of the locking member facing the lamp body, and the upper side of the latching part is provided with a guide slope. When the lamp body is installed into the receiving groove, the limiting part abuts against the guide slope to push the latching part away from the lamp body. When the limiting part descends to below the latching part, the elastic member pushes the locking member so that the latching part abuts against the upper side of the limiting part, thereby locking the lamp body. The guide slope allows the limiting part to abut against the guide slope and push the latching part away from the lamp body when the lamp body is installed into the receiving groove, thus facilitating the assembly of the lamp body relative to the receiving groove.

[0008] In an improved embodiment, the locking member has a rotating shaft rotatably connected to the receiving groove in the middle. The latching part and the push button are located at the two ends of the locking member, so that when the push button moves, the latching part is driven accordingly. Since the push button and the latching part form a lever relative to the rotating shaft, the movement of the push button can better control the latching part's engagement with the limiting part.

[0009] In an improved embodiment, the elastic element is a torsion spring or a spring, with one end connected to the lamp holder and the other end connected to the locking element, thereby providing a corresponding elastic force to the locking element.

[0010] In an improved embodiment, there are two locking components located on the left and right sides of the positioning groove, respectively. The left and right sides of the positioning groove are provided with openings, and the left and right sides of the lamp body are provided with limiting parts. The two locking components can achieve a better and more stable locking effect on the lamp body, and the operator can push the push button from the left and right sides to reduce the lateral force on the lamp holder.

[0011] In an improved embodiment, the bottom of the receiving groove is provided with a positioning platform, the power supply contact is located on the positioning platform, the lamp body is provided with a positioning part for cooperating with the positioning platform, and the pin is located on the positioning part. The positioning platform and the positioning part facilitate the alignment of the lamp body's pin with the power supply contact in the receiving groove, and the positioning platform can also support the lamp body, improving the installation stability of the lamp body in the receiving groove.

[0012] In an improved embodiment, the positioning part is groove-shaped and corresponds to the positioning platform, so that when the lamp body is inserted into the receiving slot, the positioning platform will automatically insert into the positioning part to achieve positioning and support of the lamp body.

[0013] In an improved embodiment, a base is also included. An adjustment bracket is provided on the lower side of the lamp holder. The upper part of the adjustment bracket is rotatably connected to the base via a hinge shaft. The lower part of the adjustment bracket is provided with an arc-shaped groove centered on the hinge shaft. The base is provided with a locking pin. The locking pin is inserted into the arc-shaped groove to control the relative angle between the adjustment bracket and the base, thereby realizing the function of adjustable illumination angle of the lamp holder.

[0014] In an improved embodiment, the base includes an upper cylinder and a lower cylinder that are slidably connected vertically. One of the upper and lower cylinders is provided with a fixing pin, and the other is provided with an elongated groove along the vertical direction. The fixing pin is inserted into the elongated groove to control the relative position of the upper and lower cylinders, thereby realizing the height adjustment function of the lamp holder.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1-4 The present invention provides a tunnel lighting fixture that is easy to maintain, comprising a lamp holder 1, a locking member 2, and a lamp body 3. The lamp holder 1 is provided with a receiving groove 11 with the groove facing upward and into which the lamp body 3 can be inserted. The inner side wall of the receiving groove 11 is provided with an outwardly penetrating opening 12. The locking member 2 is movably connected in the receiving groove 11. The locking member 2 is provided with a latching part 21 and a push button part 22 facing the opening 12. The lamp holder 1 is provided with an elastic member 13 acting on the locking member 2 and a power supply contact 14 facing the lamp body 3. The lamp body 3 is provided with a pin 31 corresponding to the power supply contact 14 and a limiting part 32 corresponding to the latching part 21. When the lamp body 3 is inserted into the receiving groove 11, the latching part 21 is pushed by the elastic member 13 and latched onto the limiting part 32, and the push button part 22 is pushed to the outside of the opening 12. At this time, the pin 31 and the power supply contact 14 abut against each other and conduct. When the push button part 22 is pushed to the inside of the opening 12, the locking member 2 drives the latching part 21 to disengage from the limiting part 32 so that the lamp body 3 can be taken out from the receiving groove 11.

[0022] The above solution uses a locking element 2 inside the lamp holder 1. During installation, the lamp body 3 is simply inserted into the receiving groove 11 from top to bottom. At this time, the elastic element 13 will push the buckle 21 to automatically engage with the limiting part 32 of the lamp body 3, thus locking the lamp body 3 in the receiving groove 11. At the same time, the pin 31 of the lamp body 3 will directly abut against and conduct with the power supply contact 14, eliminating the need for manual wiring. This is convenient, quick, and has good electrical connection reliability. When maintenance or replacement of the lamp body 3 is required, simply push the push button 22 into the opening 12. The locking element 2 will cause the buckle 21 to disengage from the limiting part 32, allowing the lamp body 3 to be removed from the receiving groove 11. The operation is simple and convenient.

[0023] In this embodiment, there are two locking elements 2, located on the left and right sides of the positioning groove, respectively. Openings 12 are provided on both the left and right sides of the positioning groove. Limiting parts 32 are provided on the left and right sides of the lamp body 3. The two locking elements 2 achieve a better and more stable locking effect on the lamp body 3, and the operator can push the push button 22 from both sides to reduce the lateral force on the lamp holder 1. It should be understood that the number of locking elements 2, limiting parts 32, and openings 12 can also be one, which can also achieve the locking of the lamp body 3 in the receiving groove 11. This design does not limit this.

[0024] In this embodiment, the limiting part 32 protrudes from the side wall of the lamp body 3, and the latching part 21 protrudes from the side of the locking member 2 facing the lamp body 3. The upper side of the latching part 21 is provided with a guide slope 23, which gradually slopes from bottom to top toward the inner side wall of the receiving groove 11. So when the lamp body 3 is installed into the receiving groove 11, the limiting part 32 abuts against the guide slope 23 to push the latching part 21 away from the lamp body 3. When the limiting part 32 descends to below the latching part 21, the elastic member 13 pushes the locking member 2 so that the latching part 21 abuts against the upper side of the limiting part 32, thereby locking the lamp body 3. The setting of the guide slope 23 enables the limiting part 32 to abut against the guide slope 23 and push the latching part 21 away from the lamp body 3 when the lamp body 3 is installed into the receiving groove 11, thereby realizing the convenient assembly of the lamp body 3 relative to the receiving groove 11.

[0025] Regarding the locking member 2, in this embodiment, the locking member 2 has a rotating shaft 24 rotatably connected to the receiving groove 11 in its middle. The latching part 21 and the push button part 22 are located at opposite ends of the locking member 2. Thus, when the push button part 22 moves, the latching part 21 is moved accordingly. Since the push button part 22 and the latching part 21 form a lever relative to the rotating shaft 24, the movement of the push button part 22 can better control the latching part 21's engagement with the limiting part 32. It should be understood that the locking member 2 can also have other structures. For example, one end of the locking member 2 may have a rotating shaft 24 rotatably connected to the receiving groove 11, the latching part 21 may be located in the middle of the locking member 2, and the push button part 22 may be located at the other end of the locking member 2. By pushing the push button part 22, the latching part 21 can be moved. In other words, as long as the movement of the push button part 22 can cause the latching part 21 to engage or disengage from the limiting part 32, it is considered to be within the scope of protection of this design.

[0026] In this embodiment, the elastic element 13 is a spring, with one end connected to the inner wall of the receiving groove 11 of the lamp holder 1 and the other end connected to the locking element 2 near the latching part 21 / push button part 22, thereby providing a corresponding elastic force to the locking element 2. Alternatively, in another embodiment, the elastic element 13 is a torsion spring sleeved on the rotating shaft 24, with one end connected to the inner wall of the receiving groove 11 of the lamp holder 1 and the other end connected to the locking element 2.

[0027] In this embodiment, a positioning platform 15 is provided at the bottom of the receiving groove 11, and the power supply contact 14 is provided on the positioning platform 15. The lamp body 3 is provided with a positioning part 33 for cooperating with the positioning platform 15, and the pin 31 is provided on the positioning part 33. The positioning platform 15 and the positioning part 33 are conducive to the alignment of the pin 31 of the lamp body 3 with the power supply contact 14 in the receiving groove 11. The positioning platform 15 can also support the lamp body 3, thereby improving the installation stability of the lamp body 3 in the receiving groove 11.

[0028] More specifically, the positioning part 33 is grooved and its shape corresponds to the positioning platform 15, so that when the lamp body 3 is installed into the receiving groove 11, the positioning platform 15 will automatically insert into the positioning part 33 to achieve positioning and support of the lamp body 3.

[0029] As an extension of this embodiment, it also includes a base 4, an adjustment frame 5 is provided on the lower side of the lamp holder 1, the upper part of the adjustment frame 5 is rotatably connected to the base 4 through a hinge shaft 51, the lower part of the adjustment frame 5 is provided with an arc-shaped groove 52 with the hinge shaft 51 as the center, the base 4 is provided with a locking pin 411, the locking pin 411 is inserted into the arc-shaped groove 52 to control the relative angle between the adjustment frame 5 and the base 4, thereby realizing the function of adjustable illumination angle of the lamp holder 1.

[0030] In this embodiment, the base 4 includes an upper cylinder 41 and a lower cylinder 42, which are slidably connected vertically. The upper cylinder 41 has a vertically elongated groove 412, and the lower cylinder 42 has a fixing pin 421. The fixing pin 421 is inserted into the elongated groove 412 to control the relative position of the upper cylinder 41 and the lower cylinder 42, thereby realizing the height adjustment function of the lamp holder 1. Both the fixing pin 411 and the fixing pin 421 can be bolts with nuts, thereby realizing the tightness adjustment.

[0031] It should be noted that in the description of this application, the terms "inner" and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.
