Detailed implementation manners

[0024] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation manners.

[0025] As Figures 1 to 3 shown, a light source module is disclosed in a specific embodiment of the present invention, including a mounting block 100 and an LED lamp board 200 provided on one side surface of the mounting block 100. As Figure 4 shown, a clamping hole 110 is provided in the middle of the top surface of the mounting block 100, and a first threaded hole 120 penetrating the mounting block 100 is provided in the middle of the bottom surface of the clamping hole 110; a limit cover 300 is fixedly provided on the top surface of the mounting block 100. As Figure 5As shown, the shape of the limit cover 300 is adapted to the top surface of the mounting block 100, and both ends of the limit cover 300 are open. Two clamping blocks 400 are provided inside the limit cover 300. The two clamping blocks 400 are centrosymmetric about the center of the mounting block 100 and enter and exit the inside of the limit cover 300 from the open ends of the limit cover 300. A through hole 310 is provided on the top surface of the limit cover 300 corresponding to the clamping hole 110; As Figure 7 shown, a fixing member 500, the fixing member 500 includes a threaded rod 510 and a driving part 520 fixedly provided on the top surface of the threaded rod 510. The threaded rod 510 is adapted to the first threaded hole 120. The driving part 520 is adapted to the clamping hole 110 and the through hole 310, and the rotating driving part 520 drives the two clamping blocks 400 to enter and exit the open ends of the limit cover 300 synchronously.

[0026] In the above-mentioned light source module, its structure is novel. The cooperation of the mounting block 100, the clamping hole 110, the first threaded hole 120, the limit cover 300, the clamping block 400, and the fixing member 500, as Figure 2 shown, can realize that during the rotation of the fixing member 500, the two clamping blocks 400 are driven to move and enter and exit the open ends of the limit cover 300; with this structure, the threaded rod 510 of the fixing member 500 can fix the mounting block 100 at the bottom of the mounting position, and the driving part 520 simultaneously drives the protrusion of the two clamping blocks 400 for secondary clamping and fixing, making clever use of the rotation effect of the fixing member 500 to achieve effective and stable fixing.

[0027] Furthermore, the length of the threaded rod 510 is greater than the depth of the first threaded hole 120, and the length of the driving part 520 is greater than the depth of the clamping hole 110 and less than the distance from the bottom of the clamping hole 110 to the top surface of the limit cover 300; this structural design ensures that the threaded rod 510 can protrude from the bottom of the first threaded hole 120 to achieve cooperation with the bottom of the mounting position; similarly, after installation and fixation, the top of the driving part 520 is lower than the top surface of the limit cover 300, which is convenient for the design and installation of subsequent components.

[0028] Furthermore, as Figure 5As shown, the first strip block 410, the second strip block 420 and the third strip block 430 are sequentially connected to the positioning block 400, the first strip block 410 and the third strip block 430 are parallel, the second strip block 420 is fixedly connected to the first strip block 410 and the third strip block 430 at both ends, the length of the third strip block 430 is less than the length of the first strip block 410, and the sum of the length of the first strip block 410 and the length of the third strip block 430 is less than the long side of the top surface of the installation block 100, and the first strip block 410 is provided with a second strip block 430 on the side close to the positioning hole 110. One tooth, the two locking blocks 400 are symmetrically arranged with respect to the center of the mounting block 100; the driving part 520 includes a column and a second tooth fixed to the outer wall of the column, and the second tooth of the driving part 520 is meshed with the first tooth of the two first blocks 410 for transmission; this structural design can prevent the two locking blocks 400 from interfering with each other when moving back, and ensure that there is enough movement gap between the two locking blocks 400; and the two locking blocks 400 are both meshed with the driving part 520 through the teeth, which can realize the action of synchronous outward or synchronous inward movement, and complete the effect of locking and releasing.

[0029] Furthermore, the distance between the two opposite side surfaces of the first block 410 and the third block 430 is adapted to the distance between the two opposite side walls of the limiting cover 300; this structural design can use the opposite side walls of the limiting cover 300 as guide supports to ensure stable movement of the positioning block 400.

[0030] Furthermore, the first bar block 410 is provided with a guide slot 440 which passes through the upper and lower walls of the first bar block 410, and the guide slot 440 is arranged along the length direction of the first bar block 410. The top surface of the mounting block 100 is fixed with a guide block 130 corresponding to the two guide slots 440, and the positioning block 400 moves along the guide block 130; this structural design can further limit the movement trajectory of the positioning block 400 and further provide movement guidance; and the design of the guide block 130 can prevent the positioning block 400 from being disengaged from the interior of the limit cover 300, thereby avoiding the situation where the engagement state of the driving part 520 and the positioning block 400 is disengaged.

[0031] Furthermore, a chamfer is provided at an edge of the second strip 420 on a side away from the first strip 410 and the third strip 430 .

[0032] Further, two bumps 320 are fixedly provided at the bottom of the limit cover 300. The two bumps 320 are symmetrically arranged about the center of the limit cover 300. Counterbore holes 330 are provided on the top surface of the limit cover 300 corresponding to the two bumps 320. The counterbore holes 330 penetrate through the bumps 320. Second threaded holes 140 are provided on the top surface of the mounting block 100 corresponding to the two counterbore holes 330. The limit cover 300 is fixed to the top surface of the mounting block 100 by screws; this structural design facilitates the formation of a stable fit between the limit cover 300 and the mounting block 100, providing stable structural support.

[0033] The present invention is described by way of preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
