Description

Technical Field

[0001] This utility model relates to the field of press-locking technology, and in particular to a press-locking mechanism for installation. Background Technology

[0002] In the modern lighting field, luminaires are used in a wide range of scenarios, from home indoor lighting to commercial lighting projects and the lighting needs of various industrial facilities. Stable installation and convenient adjustment of luminaires are crucial. A pressing and locking mechanism has become a key component ensuring the efficient use of luminaires. It must not only ensure that the luminaire remains securely in its set position after installation, providing stable lighting service, but also allow for convenient and quick operation when adjustments or maintenance / replacement are needed. With the continuous development of lighting technology, people's demands for the functionality and aesthetics of luminaires are increasing, prompting continuous innovation in luminaire installation and locking mechanisms to adapt to diverse installation environments and complex usage requirements.

[0003] Currently, in the field of lighting installation, most common mechanical structures employ traditional screw fixing methods or simple snap-fit ​​connections. The screw fixing method works by screwing screws into pre-drilled threaded holes in the mounting base and mounting surface, using the screw's tightening force to firmly secure the lighting fixture to the mounting surface. The simple snap-fit ​​connection method, on the other hand, uses matching snap-fit ​​structures on the lighting fixture and mounting base, utilizing the snap-fit's elastic deformation to achieve a locking and fixing effect. The principle is that the snap-fit's elasticity engages the lighting fixture within the mounting base's groove, and the friction between the snap-fit ​​and the groove maintains the lighting fixture's fixed position.

[0004] However, existing lighting fixture installation and fixing technologies have significant problems. Neither screw fixing nor simple snap-fit ​​connections effectively address the difficulty of adjusting the fixture once it's fixed in position. Once a fixture is secured with screws, adjusting its illumination angle or position requires removing the screws and reinstalling it, a complex process that can easily damage the fixture and mounting surface. While simple snap-fit ​​connections are relatively easy to install, the locking force is limited, and the snaps can easily loosen or even break during adjustments, leading to unstable fixtures and compromising safety. Furthermore, both methods present inconvenience when disassembling the fixture for maintenance or replacement, significantly reducing its usability and installation / disassembly efficiency. Therefore, a pressing and locking mechanism is proposed to address these issues. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a pressing and locking mechanism, comprising a mounting plate 19, which is used to fix to the ceiling and provide a mounting base for the entire lamp and locking device. The mounting plate 19 is provided with multiple fixing housings 1 on its side walls. The fixing housings 1 are usually made of high-strength engineering plastic, which has good toughness and durability and can withstand a certain external impact. At the same time, it provides a stable installation space for the internal locking components and other related components. The fixing housings 1 are distributed in an array. The mounting plate 19 is provided with a ceiling lamp 18 on its side walls. The fixing housings 1 are provided with locking components on their inner walls. The locking components are used to adjust the unlocking and locking positions of the ceiling lamp 18.

[0032] The locking assembly includes a housing 13, which serves as the main frame of the locking assembly. The housing 13 is made of aluminum alloy, effectively protecting internal components such as the guide rails 14 and the movable rod 11, and providing them with a stable mounting base. The bottom of the housing 13 is fixedly connected to the bottom of the inner wall of the fixed housing 1. Multiple guide rails 14, made of precision-machined metal with a smooth surface and good guiding properties, are fixedly connected to the top of the inner wall of the housing 13. The guide rails 14 guide the movement of the movable rod 11, allowing it to move up and down inside the housing 13. The guide rails 14 are arranged in a circular pattern. The movable rod 11, made of metal, is slidably connected to the inner wall of the housing 13, possessing good rigidity and wear resistance. The movable rod 13 slides smoothly along the direction of the guide rail 14. A fixed tooth 15 is fixedly connected to the top of the movable rod 11, and its tooth shape matches the tooth shape of the movable tooth 16 to achieve locking and unlocking functions. A spring 12 is sleeved on the outer wall of the movable rod 11. The main function of the spring 12 is to provide upward or downward elastic force to the movable rod 11 through its own compression and extension when the movable rod 11 is subjected to external force, assisting in locking and unlocking operations. One end of the spring 12 is fixedly connected to the bottom of the fixed tooth 15, and the other end is fixedly connected to the bottom of the inner wall of the fixed housing 1. A movable tooth 16 is provided above the fixed tooth 15, and the movable tooth 16 meshes with the fixed tooth 15. Its tooth shape precisely matches the tooth shape of the fixed tooth 15, allowing it to rotate or move under the drive of the fixed tooth 15. The teeth 15 mesh with each other, and the top of the movable tooth 16 is fixedly connected to the connecting rod 10. The top of the connecting rod 10 is fixedly connected to the positioning post 9. The top of the positioning post 9 is fixedly connected to the locking assembly. The locking assembly is used to fix the position of the lamp in conjunction with the locking assembly. The locking assembly includes a lock head 7. The bottom of the lock head 7 has a receiving groove 8. The size of the receiving groove 8 is adapted to the outer diameter of the positioning post 9. The outer wall of the positioning post 9 can slide smoothly on the inner wall of the receiving groove 8, thereby realizing a stable connection between the lock head 7 and the positioning post 9. The outer wall of the positioning post 9 is slidably connected to the inner wall of the receiving groove 8. The bottom of the ceiling lamp holder 18 is provided with multiple lamp groups 19. The lamp groups 19 are distributed in an array. The top of the lock head 7 is provided with a lamp mounting buckle 3. The outer wall of the lamp mounting buckle 3 is fixedly connected to the ceiling lamp 18. The lamp mounting buckle 3 has a locking groove 17 at its bottom. The size of the locking groove 17 is adapted to the outer diameter of the lock head 7. The outer wall of the lock head 7 can slide on the inner wall of the locking groove 17. In this way, the lamp mounting buckle 3 and the lock head 7 are connected together to achieve the installation and fixation of the lamp. The outer wall of the lock head 7 is slidably connected to the inner wall of the locking groove 17. The inner wall of the fixed housing 1 has multiple locking holes 5, the shape and size of which match the buckle 4. They are used to cooperate with the buckle 4 on the sub-housing 2 to achieve the connection and fixation between the fixed housing 1 and the sub-housing 2. The locking holes 5 are distributed on the upper, lower, left and right sides of the fixed housing 1. The sub-housing 2 is slidably connected to the inner wall of the fixed housing 1. The sub-housing 2 is usually made of the same high-strength engineering plastic as the fixed housing 1, which has good mechanical properties and appearance.The outer walls of the sub-shell 2 are all fixedly connected with buckles 4. By inserting the buckles 4 into the lock holes 5, a tight connection is achieved between the sub-shell 2 and the fixed shell 1. The buckles 4 and the lock holes 5 are aligned. Multiple limiting plates 6 are fixedly connected to the inner wall of the sub-shell 2. Their function is to restrict and position the components inside the shell. The limiting plates 6 are distributed in an array.

[0033] Specifically, when using the ceiling light's press-lock structure, to lock the light fixture, first push the movable rod 11 upwards along the guide rail 14 on the inner wall of the housing 13. As the movable rod 11 moves upwards, the fixed tooth 15 fixedly connected to its top also moves upwards. At this time, the spring 12 sleeved on the outer wall of the movable rod 11 is stretched from its normal state to its extended state due to the upward displacement of the fixed tooth 15. Simultaneously, when the fixed tooth 15 moves upwards, its inclined block contacts the inclined block of the movable tooth 16 and generates a force. Due to the restriction of the movement direction of the movable rod 11 and the fixed tooth 15 by the guide rail 14 on the inner wall of the housing 13, the fixed tooth 15, while moving upwards, drives the movable tooth 16 to move upwards and rotate around its own central axis through the interaction of the inclined blocks. This upward displacement and rotation of the movable tooth 16 is achieved under the oblique force applied by the inclined block of the fixed tooth 15 and the constraint of its own tooth profile engagement with the fixed tooth 15. The displacement and rotation of tooth 16 cause the connecting rod 10, which is fixedly connected to its top, to also move and rotate synchronously. The movement of the connecting rod 10 then drives the positioning pin 9, which is fixedly connected to its top, to rotate and move synchronously. Finally, the movement of the positioning pin 9 pushes the lock head 7 connected to it into the locking groove 17 at the bottom of the lamp mounting buckle 3, thus completing the locking of the lamp. When it is necessary to unlock the lamp, push the movable rod 11 upward again. The movable rod 11 still slides upward along the guide rail 14 on the inner wall of the outer shell 13, causing the fixed tooth 15 to move upward again. Under the interaction with the inclined block of the movable tooth 16, the inclined block of the fixed tooth 15 disengages from its current position of engaging with the inclined block of the movable tooth 16. Due to the tooth shape design of the fixed tooth 15 and the movable tooth 16 and the angle relationship of the inclined blocks, the interaction force between the inclined blocks changes when the fixed tooth 15 moves upward, thus allowing the inclined block of the fixed tooth 15 to disengage. Simultaneously, under the action of spring 12, which had previously stored elastic potential energy due to stretching, it releases this energy, pulling down one end of the fixed tooth 15 to restore it to its original position. The reset of the fixed tooth 15 causes the moving tooth 16, which interacts with it, to also return to its original position. After the inclined block of the fixed tooth 15 disengages, the moving tooth 16, influenced by its own structure and its connection with the fixed tooth 15, returns to its initial position. As the moving tooth 16 returns to its original position, the connecting rod 10 and the positioning pin 9 also return to their initial positions. The connecting rod 10 drives the positioning pin 9 to rotate and displace in the opposite direction. The movement of the positioning pin 9 causes the lock head 7 connected to it to disengage from the inner wall of the lock groove 17. Driven by the positioning pin 9, the lock head 7 moves in the opposite direction to when it was locked, sliding out from the inner wall of the lock groove 17, thus unlocking the lamp.

[0034] Working principle: When using the press-lock mechanism of this ceiling light, to lock the light fixture, the movable rod 11 first pushes the fixed tooth 15 upward to displace it. At this time, the spring 12 is affected by the displacement of the fixed tooth 15 and extends. Simultaneously, with the cooperation of the inclined block of the fixed tooth 15 and the movable tooth 16 and the guide rail 14 on the inner wall of the outer shell 13, the fixed tooth 15 drives the movable tooth 16 to move upward and rotate. The displacement and rotation of the movable tooth 16 causes the connecting rod 10 to move and rotate synchronously. The movement of the connecting rod 10 drives the positioning pin 9 to rotate synchronously. The movement and displacement ultimately push the lock head 7 into the locking groove 17 at the bottom of the lamp mounting buckle 3, thus locking the lamp. When it is necessary to unlock the lamp, the movable rod 11 is pushed upward again, causing the fixed tooth 15 to move upward again. Under the influence of the inclined block of the fixed tooth 15 and the movable tooth 16, the inclined block of the fixed tooth 15 is disengaged from its current position. At the same time, under the action of the spring 12, the fixed tooth 15 returns to its original position, and the position of the movable tooth 16 also returns to its original displacement, thereby allowing the lock head 7 to disengage from the inner wall of the locking groove 17, thus unlocking the lamp.
