Description

Technical Field

[0001] The utility model relates to a locking mechanism for a lamp, belonging to the field of lamps. Background Art

[0002] Recessed lamps (such as downlights) are widely used in various scenarios, which means that recessed lamps need to meet the requirements of various application scenarios. For example, in some applications, lamps need to provide different brightness or lighting effects. If additional optical elements are applied to achieve the lighting effect without changing the lamp to the greatest extent, it is particularly desirable in terms of cost. In other applications, lamps need to have waterproof or fireproof properties. If lamps are designed and developed for each application scenario, the length of the product line will inevitably increase, which increases the cost of lamp production. In order to solve the above problems, some manufacturers provide a method of making lamps suitable for different applications by simply adding or removing accessories without changing the lamp structure.

[0003] In the prior art, when installing accessories on lamps designed by these manufacturers, it is necessary to first place the accessories on the top of the mounting base, and then place the reflector on the top of the mounting base. The installation of the accessory can be completed by rotating the reflector so that the locking protrusion fixed on the surface of the reflector can be inserted into the locking groove fixed on the top of the mounting base. However, relying solely on the engagement of the locking protrusion and the locking groove to install the accessory results in a poor fixing effect between the mounting base and the reflector, which poses a great safety hazard to the lamp.

[0028] The outer diameter of the mounting groove 2 is consistent with the inner diameter of the reflector 4, and the outer diameter of the accessory 3 is consistent with the inner diameter of the mounting groove 2. The consistency of the outer diameter of the mounting groove 2 with the inner diameter of the reflector 4 and the outer diameter of the accessory 3 with the inner diameter of the mounting groove 2 allows the reflector 4 to completely enclose the accessory 3, thereby improving the sealing and connection security between the reflector 4 and the accessory 3.

[0029] The locking seat 51 is L-shaped. The number of insert blocks 64 matches the number of insertion holes 52, and the size of the insert blocks 64 matches the size of the insertion holes 52. The number of clearance openings 65 matches the number of locking seats 51, and the size of the clearance openings 65 matches the size of the locking seat 51. The number of insert blocks 64 matches the number of insertion holes 52, and the size of the insert blocks 64 matches the size of the insertion holes 52, ensuring a one-to-one correspondence between the insert blocks 64 and the insertion holes 52. The number of clearance openings 65 matches the number of locking seats 51, and the size of the clearance openings 65 matches the size of the locking seat 51, ensuring a one-to-one correspondence between the clearance openings 65 and the locking seat 51.

[0030] The length of the first guide rod 66 is equal to the distance between the top surface of the connecting plate 61 and the top surface of the abutment plate 63, and the length of the second guide rod 74 is greater than the length of the compression spring 72. The length of the first guide rod 66 is equal to the distance between the top surface of the connecting plate 61 and the top surface of the abutment plate 63, ensuring that the first guide rod 66 does not completely separate from the connecting plate 61, and the length of the second guide rod 74 is greater than the length of the compression spring 72, ensuring that the second guide rod 74 does not completely separate from the fixing plate 71.

[0031] Specific implementation method: Select the corresponding accessory 3 according to the actual situation and put it into the installation groove 2, then make sure that the clearance opening 65 can face the locking seat 51 and put the support plate 63 to the top of the mounting seat 1, then press the connecting plate 61 toward the mounting seat 1 so that it squeezes the return spring 62 connected to it and drives the first guide rod 66 connected to the support plate 63 to slide along the inner wall of the connecting plate 61, then rotate the reflector 4 in the clockwise direction so that it drives the support plate 63 to slide along the top of the mounting seat 1, and then drives the plug 64 connected to the top of the connecting plate 61 to move synchronously until The positioning block 8 connected to the outer side of the abutment plate 63 contacts the locking seat 51.
