Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board with an auxiliary installation structure. Background Art

[0002] The circuit board is an important electronic component. It is the carrier and support for the electrical connection of electronic components. The circuit board consists of a circuit board body and mounting holes. When installing the circuit board to the housing, place the circuit board body on the housing so that the mounting holes on the housing and the mounting holes on the circuit board are horizontally and vertically aligned, and then tighten them with screws.

[0003] The inventor found in his daily work that when installing a circuit board, when installing the circuit board under a shell, workers are required to lift the circuit board to ensure that the mounting holes on the circuit board are horizontally and vertically aligned with the mounting holes on the shell. Since the workers need to tighten the screws while lifting the circuit board, other mounting holes may deviate from the mounting holes on the shell and need to be realigned, which leads to low installation efficiency. Utility Model Content

Since the worker needs to tighten the screws while lifting the circuit board, other mounting holes may deviate from the mounting holes on the shell and need to be realigned, which leads to low installation efficiency. A circuit board with an auxiliary mounting structure is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a circuit board with an auxiliary mounting structure, comprising a circuit board body, a mounting hole is opened on the front of the circuit board body, an auxiliary mounting component is arranged on the inner wall of the mounting hole, a protective component is arranged on the front of the circuit board body, the auxiliary mounting component comprises a circular cylinder arranged on the inner wall of the mounting hole, a fixing ring is fixedly connected to one end of the circular cylinder, operating holes are opened on both sides of the inner arc surface of the circular cylinder, and the circular cylinder expands with the help of the operating holes.

[0006] The effect achieved by the above-mentioned components is: by setting up the installation assembly, when installing the circuit board to the shell, the circular cylinders in the four mounting holes on the circuit board are pushed into the mounting holes on the shell, and the circular cylinders on both sides of the operating hole are expanded and squeezed into the mounting holes through the expansion mechanism, thereby positioning the circuit board so that the fixing ring supports the circuit board. When installing the screws, by releasing the expansion mechanism, one circular cylinder is pulled out and the screws are installed in the mounting holes, thereby avoiding the effect of twisting the screws, which may cause other mounting holes to deviate from the mounting holes on the shell and require realignment.

[0007] Preferably, the inner wall of the circular cylinder is rotatably connected with a folding rod, and a fold is formed on the surface of the folding rod.

[0008] The effect achieved by the above components is that the folding rod can be stretched and contracted by setting the folding lines.

[0009] Preferably, the folding rod is extended and contracted by means of the folding line, and a plurality of identical anti-slip strips are fixedly connected to the outer arc surface of the circular cylinder.

[0010] The effect achieved by the above components is: by setting the anti-slip strip, which is a rubber block, the friction between the circular cylinder and the housing installation hole is increased.

[0011] Preferably, the plurality of anti-slip strips are evenly distributed on the outer arc surface of the circular cylinder, and one end of the folding rod is fixedly connected to a draw rope.

[0012] The effect achieved by the above components is that the folding rod is retracted by pulling the draw cord.

[0013] Preferably, a spring is provided on one side of the folding rod, and both ends of the spring are fixed to the folding rod.

[0014] The effect achieved by the above components is: by arranging the spring, the spring squeezes the folding rod, thereby expanding the circular cylinders on both sides of the operating hole.

[0015] Preferably, the protection component includes a rubber pad disposed on the circuit board body, and the rubber pad is located at the mounting hole.

[0016] The effect achieved by the above components is that when the screw is tightened in the mounting hole, the rubber pad contacts the screw, thereby preventing the screw from being overloaded.

[0017] Preferably, a mounting groove is provided on the front side of the circuit board body, and the mounting groove is used for installing a rubber pad.

[0018] The effect achieved by the above components is: the rubber pad is installed by setting the installation groove.

[0019] Preferably, a limiting ring is provided on the inner wall of the installation groove, and the limiting ring is fixed to the rubber pad.

[0020] The effect achieved by the above components is: the rubber pad is limited by setting the limiting ring.

[0021] In summary, the beneficial effects of the utility model are:

[0022] In the utility model, by setting a mounting assembly, when installing the circuit board to the shell, the circular cylinders in the four mounting holes on the circuit board are pushed into the mounting holes on the shell, and the circular cylinders on both sides of the operating hole are expanded and squeezed into the mounting holes through the expansion mechanism, so that the circuit board is positioned so that the fixing ring supports the circuit board, and when installing the screws, the expansion mechanism is released, a circular cylinder is pulled out, and the screws are installed into the mounting holes, so as to avoid the effect of twisting the screws, which may cause other mounting holes to deviate from the mounting holes on the shell and need to be realigned. This solves the problem that when installing the circuit board under the shell, the worker needs to lift the circuit board to ensure that the mounting holes on the circuit board are horizontally and vertically aligned with the mounting holes on the shell. Since the worker needs to twist the screws while lifting the circuit board, other mounting holes may deviate from the mounting holes on the shell and need to be realigned, which leads to low installation efficiency.

By setting the installation component, when installing the circuit board to the shell, the circular cylinders 21 in the four mounting holes 4 on the circuit board are pushed into the mounting holes 4 on the shell, and the circular cylinders 21 on both sides of the operating holes 23 are expanded and squeezed into the mounting holes 4 through the expansion mechanism, so as to position the circuit board so that the fixing ring 22 supports the circuit board. When installing the screw, the expansion mechanism is released, one circular cylinder 21 is pulled out, and the screw is installed in the mounting hole 4, so as to avoid twisting the screw, which may cause other mounting holes 4 to deviate from the mounting holes 4 on the shell and need to be realigned. To achieve the effect of aligning the cylinder 21, the inner wall of the circular cylinder 21 is rotatably connected with a folding rod 24, and a folding mark 25 is provided on the surface of the folding rod 24. By setting the folding mark 25, the folding rod 24 is extended and contracted, and the folding rod 24 is extended and contracted with the help of the folding mark 25. A plurality of identical anti-slip strips 27 are fixedly connected to the outer arc surface of the circular cylinder 21. By setting the anti-slip strips 27, the anti-slip strips 27 are rubber blocks, and the friction between the circular cylinder 21 and the shell mounting hole 4 is increased. The plurality of anti-slip strips 27 are evenly distributed on the outer arc surface of the circular cylinder 21. A pull rope 28 is fixedly connected to one end of the folding rod 24. The pull rope 28 is pulled to shrink the folding rod 24. A spring 26 is provided on one side of the folding rod 24. Both ends of the spring 26 are fixed to the folding rod 24. By setting the spring 26, the spring 26 squeezes the folding rod 24, thereby expanding the circular cylinder 21 on both sides of the operating hole 23.

[0031] Reference Figure 3 and Figure 4 As shown, in this embodiment: the protection component 3 includes a rubber pad 31 arranged on the circuit board body 1, and the rubber pad 31 is located at the mounting hole 4.

By setting the mounting assembly, when installing the circuit board to the housing, the circular cylinders 21 in the four mounting holes 4 on the circuit board are pushed into the mounting holes 4 on the housing, and the spring 26 is set so that the spring 26 squeezes the folding rod 24, so that the circular cylinders 21 on both sides of the operating hole 23 expand, so that the circular cylinders 21 on both sides of the operating hole 23 expand and squeeze into the mounting holes 4, thereby positioning the circuit board so that the fixing ring 22 holds the circuit board. When installing the screws, By pulling the pull rope 28, the folding rod 24 is contracted, a circular cylinder 21 is pulled out, and a screw is installed in the mounting hole 4, so as to avoid the situation that turning the screw may cause other mounting holes 4 to deviate from the mounting holes 4 on the shell and need to be realigned. By setting the fold mark 25, the folding rod 24 is stretched and contracted, and by setting the anti-slip strip 27, the anti-slip strip 27 is a rubber block, which increases the friction between the circular cylinder 21 and the mounting hole 4 of the shell.

By setting the mounting groove 32, the rubber pad 31 is installed, and by setting the limit ring 33, the rubber pad 31 is limited.
