[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0022] Example:
[0023] As attached Figure 1 To Attachment Figure 5 As shown:
[0024] The utility model provides a double-wire locking composite aluminum-based circuit board 6, comprising an aluminum substrate 1, a plurality of longitudinal grooves 2 and transverse grooves 3 are arranged at the top of the aluminum substrate 1, the longitudinal grooves 2 and the transverse grooves 3 are vertically arranged, and the longitudinal grooves 2 and the transverse grooves 3 are connected to each other, a first locking wire 4 is installed at one end of the plurality of longitudinal grooves 2, a second locking wire 5 is installed at one end of the plurality of transverse grooves 3, and a locking mechanism is installed at the other end of the first locking wire 4 and the second locking wire 5, a circuit board 6 is installed at the top of the aluminum substrate 1, a plurality of longitudinal card blocks 7 and transverse card blocks 8 are installed at the bottom of the circuit board 6, a threading groove 9 is penetrated on one side of the longitudinal card block 7 and one side of the transverse card block 8, and a threading hole 10 is penetrated on the peripheral side of the aluminum substrate 1 at a position close to each longitudinal groove 2 and transverse groove 3.
[0025] The longitudinal clamping block 7 matches the longitudinal groove 2 in position and size, so that the circuit board 6 can be quickly clamped onto the aluminum substrate 1 .
[0026] The transverse clamping block 8 matches the position and size of the transverse groove 3 , so that the circuit board 6 can be quickly clamped onto the aluminum substrate 1 .
[0027] The locking mechanism includes a column 11, a mounting groove 12 is provided at the top of the column 11, a thread is provided at the top of the mounting groove 12, a movable block 13 is connected to the inner thread of the mounting groove 12, a trapezoidal block 14 is installed at the bottom of the movable block 13, four spherical grooves 15 are equidistantly provided on the circumference of the column 11, and a ball 16 is movably installed in the spherical groove 15. When the first locking line 4 or the second locking line 5 needs to be fixed, the movable block 13 is rotated, and the movable block 13 moves upward in the mounting groove 12, driving The trapezoidal block 14 moves upward so that one side of the trapezoidal block 14 is in close contact with one side of the ball 16, thereby fixing the ball 16 in the spherical groove 15. When the first locking line 4 or the second locking line 5 needs to be removed, the movable block 13 is rotated in the opposite direction so that the movable block 13 moves downward in the mounting groove 12, driving the trapezoidal block 14 to move downward. At this time, the hypotenuse of the trapezoidal block 14 is close to one side of the ball 16, thereby no longer limiting the ball 16, allowing the ball 16 to move in the spherical groove 15.
[0028] Among them, one side of the ball 16 is located in the installation groove 12, and the other side of the ball 16 is located on the outside of the column 11, so that the trapezoidal groove can be against one side of the ball 16 to limit and fix the ball 16. At this time, the other side of the ball 16 is located on the outside of the column 11, which has a limiting effect on the column 11 and prevents the column 11 from sliding into the transverse groove 3 or the longitudinal groove 2.
[0029] The movable block 13 is provided with a knob 17 at one end outside the mounting groove 12 to facilitate the rotation of the movable block 13 .
[0030] The working principle of this embodiment is as follows: the staff first aligns the aluminum substrate 1 with the circuit board 6, aligns the longitudinal card block 7 with the longitudinal groove 2 and engages, and aligns the transverse card block 8 with the transverse groove 3 and engages. After the engagement is completed, the first locking wire 4 is guided to alternately pass through the threading groove 9 on each longitudinal card block 7, and the second locking wire 5 is guided to alternately pass through the threading groove 9 on each transverse card block 8. After the threading is completed, the knob 17 is rotated to move the movable block 13 upward in the installation groove 12, driving the trapezoidal block 14 to move upward, so that the ladder block 14 can move upward. One side of the trapezoidal block 14 is in close contact with one side of the ball 16, thereby fixing the ball 16 in the spherical groove 15. When the first locking line 4 or the second locking line 5 needs to be removed, the movable block 13 is rotated in the opposite direction to move the movable block 13 downward in the mounting groove 12, thereby driving the trapezoidal block 14 to move downward. At this time, the hypotenuse of the trapezoidal block 14 is close to one side of the ball 16, thereby no longer limiting the ball 16, allowing the ball 16 to move in the spherical groove 15, thereby facilitating the removal of the first locking line 4 and the second locking line 5.
