Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to an automatic tripping mechanism and lighting equipment. Background Technology
[0002] In the field of outdoor lighting, to ensure the normal operation of lighting fixtures in complex environments, some outdoor lighting fixtures use a snap-locking method to lock the upper and lower shells of the fixture to achieve the waterproof function of the housing. That is, the upper and lower shells are tightly connected by a snap-locking structure, thereby effectively preventing external moisture from entering the interior of the lighting fixture.
[0003] However, the latches only have the single function of locking the upper and lower shells. During long-term use, due to prolonged locking, even if installation and maintenance personnel actively loosen the latches, the upper and lower shells may still remain locked due to compression and deformation. When performing lamp maintenance, installation and maintenance personnel often need to use tools to forcibly pry open the upper and lower shells, which not only increases the difficulty of maintenance but also easily damages the lamp's outer shell, affecting the convenience of maintenance and the lamp's lifespan. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic release mechanism and lighting equipment to solve the problem that the current waterproof lamp housing is difficult to open.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An automatic release mechanism includes a base, a cover, a first latch, and a second latch;
[0007] The first buckle has a head end and a tail end, the head end of the first buckle is provided with a push block extending away from the tail end, and the head end of the first buckle is rotatably connected to the edge of the base.
[0008] One end of the second buckle is rotatably connected to the first buckle, and the other end of the second buckle is engaged with the edge of the cover when the cover and the base are fastened together.
[0009] The swing trajectory of the push block intersects with the cover. When the first buckle swings relative to the base, the second buckle disengages from the edge of the cover, and the push block pushes the cover to separate the cover from the base.
[0010] Preferably, the edge of the cover is provided with a snap-fit block, and the end of the second buckle is provided with a locking hook, which snaps into the snap-fit block when the cover and the base are fastened together.
[0011] Preferably, the cover is provided with a connecting component, the connecting component having a first contact surface disposed opposite to the push block;
[0012] The first contact surface has a first end and a second end. When the cover and the base are engaged, the first end is located outside the swing trajectory of the push block, and the second end is located inside the swing trajectory of the push block. When the first buckle swings relative to the base, the push block slides relative to the first contact surface and pushes the cover.
[0013] Preferably, the push block has a second contact surface, and when the first buckle swings relative to the base, the second contact surface slidably abuts against the cover and pushes the cover.
[0014] Preferably, the first end of the first buckle is provided with a first pivot, which is rotatably connected to the base.
[0015] Preferably, the base is provided with a connecting groove, the opening of the connecting groove is disposed away from the cover, and the end of the first rotating shaft is slidably disposed in the connecting groove.
[0016] Preferably, the second end of the first contact surface is provided with a protrusion, and the push block pushes the cover when it abuts against the protrusion.
[0017] Preferably, the first buckle is provided with a reinforcing rib, one end of which is connected to the push block.
[0018] Preferably, the first buckle is provided with a receiving groove, and the second buckle is located in the receiving groove when the cover and the base are fastened together.
[0019] To solve the same technical problem, this utility model also provides a lighting device, including the automatic tripping mechanism as described above.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] The first latch is rotatably connected to the edge of the base, and one end of the second latch is rotatably connected to the first latch, while the other end is engaged with the edge of the cover. The first and second latches can lock the interlocked cover and base. The first latch has a push block at its head, and the swing trajectory of the push block intersects with the cover. When the first latch swings relative to the base, the second latch disengages from the edge of the cover to release the lock on the cover and base. At the same time, the push block pushes the cover to separate the cover and base. Installation and maintenance personnel no longer need to pry open the cover and base with special tools, which improves the service life of the cover and base and reduces the difficulty of product maintenance.

[0034] Example 1
[0035] Combination Figures 1 to 8 As shown, the automatic release mechanism of this utility model is schematically illustrated, including a base 30, a cover 40, a first buckle 10, and a second buckle 20.
[0036] Combination Figure 6 and Figure 8 As shown, the first latch 10 has a head end 11 and a tail end 12. The head end 11 of the first latch 10 is provided with a push block 111, which extends away from the tail end 12 of the latch. The head end 11 of the first latch 10 is rotatably connected to the edge of the base 30. One end of the second latch 20 is rotatably connected to the tail end 12 of the first latch 10. The other end of the second latch 20 is engaged with the edge of the cover 40 when the cover 40 and the base 30 are fastened together. The edge of the cover 40 is provided with a locking block 41, and the end of the second latch 20 is provided with a locking hook 21. When the cover 40 and the base 30 are fastened together, the locking hook 21 is engaged with the locking block 41. The locking block 41 and the locking hook 21 can prevent the end of the second latch 20 from sliding relative to the edge of the cover 40.
[0037] When the cover 40 and the base 30 are fastened together, the end of the second latch 20 is first engaged with the edge of the cover 40. Force is applied to the other end of the second latch 20 to pry it open, forcing it to swing around the connection point between itself and the cover 40. The first latch 10 swings relative to the base 30 until the line connecting the two ends of the second latch 20 swings from one side of the tail end 12 of the first latch 10 to the other side. The first latch 10 and the second latch 20 are then positioned side-by-side, locking the base 30 and the cover 40 together. Preferably, the first latch 10 has a receiving groove 14. When the cover 40 and the base 30 are fastened together, the second latch 20 is located within the receiving groove 14 to prevent the second latch 20 from protruding outwards and increasing the risk of accidental collisions, while also improving the product's aesthetic appearance.
[0038] The swing trajectory of the push block 111 intersects with the cover 40. During the process of unlocking the base 30 and the cover 40, the first latch 10 swings relative to the base 30, causing the second latch 20 to swing relative to the cover 40. The end of the second latch 20 disengages from the edge of the cover 40. The push block 111 pushes the cover 40 to separate the cover 40 from the base 30. That is, during the process of the first latch 10 swinging to unlock the cover 40 and the base 30, the push block 111 pushes the cover 40 away from the base 30. This structure eliminates the need for maintenance personnel to pry open the base 30 and the cover 40 with special tools, reducing the difficulty of product maintenance.
[0039] Specifically, such as Figures 5 to 7 The cover 40 has a connecting component 42 on the side facing the base 30. The connecting component 42 has a first contact surface 421 that is opposite to the push block 111. The opening of the concave surface of the first contact surface 421 faces the push block 111. The first contact surface 421 has a first end 421a and a second end 421b. When the cover 40 and the base 30 are engaged, the first end 421a is located outside the swing trajectory of the push block 111, and the second end 421b is located inside the swing trajectory of the push block 111. This causes the swing trajectory of the push block 111 to intersect the first contact surface 421. When the first latch 10 swings relative to the base 30 to release the lock on the base 30 and the cover 40, the push block 111 swings along with the first latch 10. The end of the push block 111 gradually approaches the first contact surface 421. After the push block 111 contacts the first contact surface 421, the push block 111 slides relative to the first contact surface 421. At this time, the push block 111 slides on the first contact surface 421 from the first end 421a to the second end 421b. The push block 111 pushes against the first contact surface 421, thereby pushing the cover 40 away from the base 30. The shape of the first contact surface 421 itself also makes the sliding of the push block 111 relative to it smoother. The second end 421b of the first contact surface 421 is provided with a protrusion 421c. The push block 111 slides relative to the first contact surface 421 until the push block 111 abuts against the protrusion 421c. As the push block 111 continues to swing, the push block 111 pushes the protrusion 421c, thereby causing the cover 40 to detach from the base 30.
[0040] Correspondingly, the push block 111 has a second contact surface 111a, such as Figure 8 The second contact surface 111a is convex. When the first buckle 10 swings relative to the base 30, the second contact surface 111a slidably abuts against the second contact surface 111a on the cover 40 and pushes the cover 40. Since the push block 111 swings with the first buckle 10 relative to the base 30, there is relative sliding between the push block 111 and the first contact surface 421. The setting of the second contact surface 111a can make the sliding between the push block 111 and the first contact surface 421 smoother.
[0041] Furthermore, the first end 11 of the first latch 10 is provided with a first rotating shaft 112, which is rotatably connected to the base 30. The base 30 is provided with a connecting groove 31, which has a U-shaped cross-section and its opening is located away from the cover 40. The end of the first rotating shaft 112 is slidably disposed in the connecting groove 31. When the first latch 10 and the second latch 20 lock the cover 40 and the base 30, the first rotating shaft 112 is located at the bottom of the connecting groove 31. The connecting groove 31 can provide the locking force required for the first latch 10. When the first latch 10 and the second latch 20 are unlocked, the installation and maintenance personnel can apply force to force the first rotating shaft 112 to disengage from the connecting groove 31, so as to remove the first latch 10 from the base 30 for easy replacement and maintenance.
[0042] In addition, such as Figure 8 The first buckle 10 is provided with a reinforcing rib 13 arranged perpendicularly thereto. One end of the reinforcing rib 13 is connected to the push block 111. The reinforcing rib 13 can improve the structural strength of the push block 111 so as to prevent the push block 111 from breaking due to excessive force.
[0043] Example 2
[0044] like Figure 1 , Figure 2 and Figure 4 This embodiment discloses a lighting device 1, including a bracket 60 and an automatic release mechanism as described above, and a light-emitting element 50 for lighting is provided on the base 30.
[0045] The bracket 60 is detachably connected to the base 30 and can be installed on an existing fixed structure (such as a lamp post). The number of first buckles 10 and second buckles 20 is the same and there are multiple of each. Each first buckle 10 corresponds to one second buckle 20, and the multiple first buckles 10 are evenly arranged on the outer edge of the base 30.
[0046] In summary, the first buckle 10 has its head end 11 rotatably connected to the edge of the base 30, and one end of the second buckle 20 is rotatably connected to the tail end 12 of the first buckle 10, while the other end is engaged with the edge of the cover 40. The first buckle 10 and the second buckle 20 can lock the interlocked cover 40 and base 30. The head end 11 of the first buckle 10 is provided with a push block 111. The swing trajectory of the push block 111 intersects with the cover 40. When the first buckle 10 swings relative to the base 30, the second buckle 20 disengages from the edge of the cover 40 to release the lock on the cover 40 and base 30. At the same time, the push block 111 pushes the cover 40 to separate the cover 40 and base 30. The installation and maintenance personnel no longer need to pry open the cover 40 and base 30 with special tools, which improves the service life of the cover 40 and base 30 and reduces the difficulty of product maintenance.
[0047] 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 description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
