Detailed Implementation
[0023] The waterproof testing fixture for downlights disclosed in this utility model is designed specifically for downlights that only require waterproof testing on the front, while the back must be waterproofed during testing. Through modular design, reliable sealing design and flexible locking mechanism, it simplifies the overall structure while ensuring waterproof performance and versatility, effectively solving the problems of poor adaptability and unstable waterproof effect of traditional testing fixtures.
[0024] exist Figure 1 In the illustrated embodiment, the fixture uses the housing 7 as the core testing space and is assembled using rectangular plates 14, balancing structural stability and dimensional adjustability. The housing 7 is composed of several processed rectangular plates 14, preferably made of PMMA board. PMMA board not only has good transparency, facilitating observation of the downlight 3 during testing, but also possesses corrosion resistance and high strength, meeting the requirements of long-term water environment testing. During assembly, a two-component polyurethane structural adhesive 10 is used for bonding and fixing. This waterproof adhesive 10 has high bonding strength and excellent waterproof performance, effectively preventing water leakage at the joints of the housing 7 and ensuring the airtightness of the testing environment. The housing 7, assembled from rectangular plates 14, reduces costs. One side of the rectangular plate 14 is shifted inwards and fixed, creating a space that serves as an installation groove 17, reserving a dedicated position for subsequent installation of waterproof connectors 8 or other testing accessories. This avoids interference between accessory installation and downlight 3 testing, optimizing the spatial layout of the fixture.
[0025] exist Figure 1 In the preferred embodiment shown, the mounting groove 17 on one side of the housing 7 further enhances the practicality and functional expandability of the tooling. The bottom of the mounting groove 17 is open, facilitating the installation of components such as the first mounting hook 11. Arc-shaped first mounting hooks 11 are provided at the bottom ends of both side walls. The arc structure reduces stress concentration and enhances the load-bearing capacity and durability of the mounting hooks. The presence of the mounting groove 17 allows for the centralized installation of accessories such as the waterproof connector 8, avoiding waterproofing risks caused by openings in other parts of the housing 7. It also makes the connection lines of the accessories more organized, facilitating later maintenance and repair. For example, during waterproof testing, external water supply equipment or testing instruments need to be connected via the waterproof connector 8. The mounting groove 17 provides a stable installation base for these accessories, ensuring a secure connection during testing, preventing loosening or leakage, and guaranteeing the smooth progress of the test.
[0026] exist Figure 1 and Figure 4In the preferred embodiment shown, the hinged connection between the top cover 1 and the housing 7 simplifies the opening and closing operation of the tooling and improves ease of use. Two right-angle hooks 12 are provided at both ends of one side of the top cover 1, with their openings facing outwards, precisely corresponding to and hinged with the first mounting hooks 11 on both sides of the mounting groove 17 of the housing 7. This hinged structure allows the top cover 1 to flexibly rotate around the hinge point, fully exposing the internal space of the housing 7 when opened, facilitating the insertion and removal of the downlight 3; when closed, it can quickly align with the housing 7 without repeated adjustments. The right-angle hook design ensures the stability of the hinged connection, preventing disengagement during opening and closing. Simultaneously, the right-angle structure, combined with the arc-shaped first mounting hooks 11, reduces wear at the hinge point and extends service life. Compared to traditional bolt fixing, the hinged design allows the top cover 1 to be opened and closed without tools, significantly shortening test preparation time and improving test efficiency.
[0027] exist Figure 2 , Figure 3 and Figure 5 In the preferred embodiment shown, the sealing design of the waterproof ring 2 between the top cover 1 and the housing 7 is crucial to ensuring the effectiveness of the waterproof test. A first fixing groove 23 is provided on the upper surface of the top cover 1 along the edge of the bottom of the housing 7. The first fixing groove 23 is continuously arranged along the length of the four sides of the top cover 1, forming a closed annular structure. The waterproof ring 2 has a T-shaped cross-section, with its bottom end precisely embedded in the first fixing groove 23. The T-shaped structure effectively prevents the waterproof ring 2 from shifting or falling off during the test, ensuring the reliability of the seal. When the top cover 1 is closed and locked, the waterproof ring 2 is compressed between the bottom of the housing 7 and the top cover 1, tightly fitting the contact surfaces of both, completely sealing the gaps and preventing test water from leaking from the connection. This sealing structure is simple and efficient, achieving excellent waterproof performance without the need for complex sealing components. Furthermore, the T-shaped waterproof ring 2 is easy to replace, reducing the maintenance cost of the tooling.
[0028] exist Figure 2 , Figure 3 and Figure 6In the preferred embodiment shown, the locking buckles 5 on the side of the housing 7 cooperate with the fixing members 9 to achieve a firm lock between the top cover 1 and the housing 7, further enhancing the sealing effect. Several locking buckles 5 are evenly hinged to the side of the housing 7, with locking rings 18 at their bottom ends. When the top cover 1 is closed, the locking rings 18 can engage with the slots 19 on the lower surface of the top cover 1, initially fixing the position of the top cover 1. To prevent the hinge mechanism from loosening during testing, the fixing members 9 can be used to lock the locking buckles 5. The top of the locking buckle 5 has a through-hole 20, and the end of the fixing member 9 installed inside abuts against the side of the housing 7. At this time, the locking buckles 5 cannot rotate, thus completing the locking. This double-fixed locking method can effectively resist the impact of internal water pressure on the top cover 1 during testing, preventing the top cover 1 from loosening and causing leakage, and ensuring the stability of the testing environment. At the same time, the number of locking buckles 5 can be flexibly set according to the size of the housing 7 to ensure that the locking force is evenly distributed across the entire contact surface, avoiding sealing failure due to insufficient local pressure.
[0029] This utility model presents a waterproof testing fixture for downlights. It utilizes a box body 7 constructed from rectangular plates 14, a hinged opening and closing structure, a T-shaped waterproof ring 2 for sealing, and a double locking mechanism to create a simple, reliable, and versatile testing device. This fixture can perform frontal waterproof testing on downlights 3 of different specifications without complex operations, effectively reducing testing costs, improving testing efficiency, and providing a reliable solution for the quality inspection of downlights 3.
[0030] exist Figure 5 In the preferred embodiment shown, the second fixing groove 24 of the waterproof ring 2 is designed to create a "two-way fit" sealing structure, significantly improving the waterproof reliability of the tooling. A rectangular second fixing groove 24 is provided along the entire length of the upper surface of the waterproof ring 2. When the box 7 and the top cover 1 are closed, the bottom end of the box 7 is precisely embedded in the second fixing groove 24, forming a tight wrap with the waterproof ring 2. This design allows the waterproof ring 2 to connect to the top cover 1 simultaneously through the first fixing groove 23 at the bottom and to the box 7 through the second fixing groove 24 at the top, forming a double-fixed sealing system that completely eliminates the leakage problems that may occur with traditional single-sealing surfaces. The waterproof ring 2 uses 10 rings of high-quality waterproof adhesive, possessing good elasticity and water resistance. When compressed by the box 7 and the top cover 1, it can fully fill the tiny gaps in the contact surface, further enhancing the sealing effect. The rectangular structure of the second fixing groove 24 precisely matches the shape of the bottom end of the box 7, ensuring a tight wrap and avoiding local sealing failure due to shape mismatch. This provides double protection for the sealing of the test environment and ensures the accuracy of the waterproof test results.
[0031] exist Figure 6In the preferred embodiment shown, the hinged structure design between the locking buckle 5 and the housing 7 balances locking stability with operational flexibility. The top of the locking buckle 5 is hinged to the top of the connector 22, and the bottom of the connector 22 is hinged to the hinge seat 21 fixed to the side of the housing 7, forming a multi-node rotating structure that allows the locking buckle 5 to be flexibly adjusted in angle. The hinge seat 21 is fixed to the housing 7 by the fixing screw 4, ensuring a firm connection and effectively resisting the tension generated during locking, preventing loosening after long-term use. Crucially, a waterproof silicone pad 6 is provided between the hinge seat 21 and the housing 7. This silicone pad not only fills the installation gap between the hinge seat 21 and the housing 7, preventing test water from seeping in, but also buffers the pressure generated when the fixing screw 4 is tightened, preventing damage to the surface of the housing 7, while enhancing the shock resistance of the hinge seat 21 and improving the overall structural stability. Both ends of the connector 22 have circular cross-sections, and the bottom of the hinge seat 21 is provided with a circular hook. The bottom of the connector 22 is embedded in the circular hook and can rotate freely. This structural design reduces the frictional resistance at the hinge, making the opening and closing action of the locking buckle 5 smoother. At the same time, the cooperation between the circular hook and the circle can prevent the connector 22 from falling off, ensuring the long-term reliability of the hinge structure.
[0032] exist Figure 2 In the preferred embodiment shown, the waterproof connector 8 within the mounting slot 17 of the housing 7 facilitates the power-on testing of the downlight 3 and expands the functionality of the tooling. The waterproof connector 8 is fixedly installed within the mounting slot 17 and precisely connected to the downlight 3 within the housing 7, allowing for external wiring to power the downlight 3. During the waterproof test, not only is the waterproof performance of the downlight 3 tested, but its power-on operation in a water environment can also be simultaneously tested, determining whether the lamp has any safety hazards such as short circuits or leakage. This makes the test more comprehensive, eliminating the need for additional power-on devices and simplifying the testing process. The waterproof connector 8 itself possesses excellent waterproof performance, effectively isolating the test water and preventing safety accidents caused by contact between the wires and water, ensuring the safety and stability of the power-on test. The mounting slot 17 provides dedicated installation space for the waterproof connector 8, preventing interference with the downlight 3 or other components, while also making the wiring of external wires more organized, facilitating later maintenance and repair, and further enhancing the practicality of the tooling.
[0033] exist Figure 2In the preferred embodiment shown, the slots 16 and inserts 15 of the rectangular plate 14 reduce the installation difficulty of the housing. Adjacent rectangular plates 14 are spliced together by inserts 15 and slots 16 on their sides. The inserts 15 are precisely inserted into the slots 16 to form a stable connection structure, allowing assembly to be completed without complicated tools. The mounting holes 13 of the top cover 1 adopt a customized design, and the shape and diameter of the holes can be flexibly adjusted according to the shape and size of different lamps to ensure that all kinds of downlights 3 can be installed stably, avoiding test errors caused by loose installation. The modular structure not only reduces the manufacturing cost of tooling, but also reduces downtime caused by tooling replacement, improves testing efficiency, and is especially suitable for multi-variety, small-batch production testing scenarios, saving enterprises a lot of equipment investment costs.
[0034] The design of each component of the tooling takes into account ease of maintenance: the double fixing structure of the waterproof ring 2 facilitates quick replacement of the aged rubber ring; the fixing screw 4 of the hinge seat 21 makes disassembly and maintenance convenient; at the same time, the overall structure of the tooling is simple, the number of parts is small, the assembly difficulty is low, and the skill requirements for operators are not high, which further improves the efficiency of the testing work.
[0035] During the actual testing process, the synergistic effect of each component fully demonstrated the advantages of the tooling: First, according to the size of the downlight 3 to be tested, a box 7 of appropriate size was assembled by the cooperation of the insert 15 and the slot 16, and the waterproof connector 8 was installed in the mounting groove 17 and connected to the wiring terminal of the downlight 3; then, the downlight 3 was fixed in the corresponding mounting hole 13 of the upper cover 1 to ensure that the lamp mounting surface was correct; next, the waterproof ring 2 was embedded in the first fixing groove 23 of the upper cover 1, and the upper cover 1 was flipped over to close with the box 7 through the hinge structure, so that the bottom end of the box 7 was embedded in the second fixing groove 24 of the waterproof ring 2, forming a double seal; then, the locking buckle 5 was fastened, and the angle was adjusted by the cooperation of the connector 22 and the hinge seat 21, so that the locking ring 18 was inserted into the slot 19 of the upper cover 1, and the fixing part 9 was tightened to complete the secure locking; the fixing part 9 is preferably a bolt. Finally, the downlight 3 was powered by the external wire of the waterproof connector 8, and test water was injected into the box 7 to observe the waterproof performance and power-on operation status of the downlight 3, thus completing the comprehensive test. After the test, loosen the locking buckle 5, flip the top cover 1 to take out the spotlight 3. The whole process is simple and does not require complicated disassembly steps.
[0036] This invention constructs a waterproof testing fixture for downlights that is waterproof, reliable, easy to operate, and highly versatile. This fixture utilizes the double sealing of the waterproof ring 2, the stable hinge of the locking buckle 5, the functional expansion of the waterproof connector 8, and a modular design. It not only ensures the accuracy and safety of waterproof testing but also adapts to the testing needs of various specifications of downlights 3, effectively reducing testing costs and improving testing efficiency.
