[0024] Embodiment

[0025] As Figures 1 to 4 shown, the integrated constant voltage dimming drive device proposed by the present utility model includes a constant voltage dimming driver 1 and a plurality of tensioning screws 11 arranged linearly at both ends of the constant voltage dimming driver 1. Installation holes are provided at the bottoms of the tensioning screws 11, and a power cord 4 is inserted into the installation holes. It further includes: an installation box 2 fixedly installed directly above the tensioning screws 11 at both ends of the constant voltage dimming driver 1; a cross screwdriver head 26 provided at the bottom of the installation box 2 for rotating the plurality of tensioning screws 11. When the cross screwdriver head 26 slides down to the limit along the second sliding hole 22, the top end of the cross screwdriver head 26 will not protrude from the bottom of the second sliding hole 22. The head of the cross screwdriver head 26 is inserted into the tensioning screw 11 to a certain depth. When the cross screwdriver head 26 rotates to drive the tensioning screw 11 to rotate, the tensioning screw 11 will move up and down by a certain height at this time, and the cross screwdriver head 26 will always be inserted into the tensioning screw 11. A driving mechanism for synchronously rotating the plurality of cross screwdriver heads 26 is provided inside the installation box 2; a pressing mechanism is installed on the top of the installation box 2. After being manually pressed, the corresponding cross screwdriver head 26 rotates. The function of the pressing mechanism is that when the corresponding tensioning screw 11 does not need to be installed, the button 23 above the corresponding tensioning screw 11 can be pressed.

[0026] Further, the driving mechanism includes a rotating main rod 28 provided inside the installation box 2. One end of the rotating main rod 28 is rotatably connected to the inner wall of the installation box 2, and the other end of the rotating main rod 28 movably passes through the installation box 2 and is fixedly connected to a total screwdriver head 3. A plurality of second bevel gears 29 corresponding to the cross screwdriver heads 26 are fixedly sleeved on the rotating main rod 28. Sliding insertion rods 251 are movably sleeved on the tops of the cross screwdriver heads 26. A pair of limiting sliding rods 252 are fixedly connected to the outer walls of the sliding insertion rods 251. The function of the limiting sliding rods 252 is that when the sliding insertion rods 251 rotate, they will drive the cross screwdriver heads 26 to rotate, and the rotating cross screwdriver heads 26 will drive the tensioning screws 11 to rotate. Limiting sliding grooves 261 for clamping the limiting sliding rods 252 are provided inside the cross screwdriver heads 26. First bevel gears 25 fixedly connected to the tops of the sliding insertion rods 251 are meshed with the second bevel gears 29 directly above them.

[0027] Among them, the pressing mechanism includes a plurality of first sliding holes 21 linearly arranged at the top of the installation box 2 and corresponding to the first bevel gear 25. The inside of each first sliding hole 21 is slidably connected with a button 23. One end of the button 23 inserted into the installation box 2 is fixedly connected with an L-shaped connecting rod 24. One end of the L-shaped connecting rod 24 close to the first bevel gear 25 is in a ring-shaped sleeve form, and its function is to support the rotation of the first bevel gear 25. The other ends of the L-shaped connecting rods 24 away from the buttons 23 are rotatably sleeved with the corresponding first bevel gears 25.

[0028] Furthermore, a return spring 27 is movably sleeved on the sliding plug rod 251. The function of the return spring 27 is to push the L-shaped connecting rod 24 to drive the first bevel gear 25 to always be meshed with the corresponding second bevel gear 29, and the elastic force of the used type of return spring 27 is sufficient to make the first bevel gear 25 always be meshed with the corresponding second bevel gear 29. The top end of the return spring 27 is fixedly connected with the L-shaped connecting rod 24, and the bottom end of the return spring 27 is movably connected with the inner wall of the installation box 2. A plurality of second sliding holes 22 corresponding to the first sliding holes 21 and for the cross screwdriver head 26 to rotate are opened at the bottom of the installation box 2.

[0029] In this embodiment, when the integrated constant-voltage dimming drive device needs to be used, as Figure 1 shown, insert the corresponding power cord 4 into the corresponding installation hole at the bottom of the tension screw 11. When it is necessary to make a plurality of tension screws 11 clamp the corresponding power cords 4 at the same time, only need to use a tool to rotate the main screw head 3. The main screw head 3 drives the rotating main rod 28 to rotate, and the rotating main rod 28 drives a plurality of second bevel gears 29 to rotate. Since the second bevel gear 29 is in a spiral connection with the corresponding first bevel gear 25, the second bevel gear 29 drives the corresponding first bevel gear 25 below to rotate. Then the first bevel gear 25 drives the sliding plug rod 251 to rotate, and the sliding plug rod 251 drives the cross screwdriver head 26 to rotate through the limit slide rod 252, so that the cross screwdriver head 26 drives the corresponding tension screw 11 to rotate, and the rotated tension screw 11 can make the power cord 4 in the installation hole firmly installed. When the power cord 4 in the installation hole of one of the tension screws 11 does not need to be installed, only need to press the button 23 directly above the power cord 4 that does not need to be installed. The button 23 will slide along the first sliding hole 21. The button 23 drives the L-shaped connecting rod 24 to move downward. The L-shaped connecting rod 24 pushes the limit slide rod 252 and drives the sliding plug rod 251 to move downward until the first bevel gear 25 at the top of the sliding plug rod 251 is disengaged from the engagement with the second bevel gear 29, which is simple and easy to operate.

[0030] The preferred embodiments of the present utility model described above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of the present utility model, so that those skilled in the relevant technical fields can well understand and utilize the present utility model.
