[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figures 1 to 7 As shown, the utility model provides a circuit board 100 that is easy to fix and install, which includes a base 10, two groups of fixing components 20 and a circuit board body 30. A sliding groove 11 is provided on the right side of the base 10, and the two groups of fixing components 20 are respectively installed on the left and right sides of the base 10, wherein the fixing component 20 located on the right side is movably engaged in the sliding groove 11 and can slide left and right, and the two ends of the circuit board body 30 are respectively clamped and fixed with the two groups of fixing components 20.

[0020] The fixing assembly 20 includes a fixing seat 21, a lower clamping tooth 22, a lifting rod 23, an upper clamping tooth 24 and a clamping spring 25. A lifting slot 211 is provided on one side of the fixing seat 21, the lower clamping tooth 22 is integrally provided on one side of the fixing seat 21 and is located below the lifting slot 211, the lifting rod 23 is fixedly installed in the lifting slot 211, the upper clamping tooth 24 is clamped and installed in the lifting slot 211 and is penetrated on the lifting rod 23, the upper clamping tooth 24 and the lower clamping tooth 22 are arranged opposite to each other up and down, the clamping spring 25 is sleeved on the lifting rod 23 and its two ends are respectively against the bottom of the lifting slot 211 and the top of the upper clamping tooth 24. The left and right sides of the upper and lower surfaces of the circuit board body 30 are provided with clamping slots 31, and the clamping slots 31 correspond to the lower clamping tooth 22 and the upper clamping tooth 24 respectively.

[0021] When the circuit board body 30 needs to be installed, it is only necessary to align its left end with the fixing assembly 20 on the left side of the base 10, and then apply a horizontal thrust to the left to push the circuit board body 30 between the lower clamping teeth 22 and the upper clamping teeth 24. Under the action of the clamping spring 25, the two clamping teeth will clamp the left end of the circuit board body 30. Then, make sure that the right end of the circuit board body 30 is in the same horizontal line as the fixing assembly 20 on the right, and then push the fixing assembly 20 on the right side to the left along the sliding groove 11 until the two clamping teeth of the fixing assembly 20 on the right side clamp the right end of the circuit board body 30, and the circuit board can be easily fixed and installed.

[0022] The circuit board 100 that is easy to fix and install also includes an elastic stretching component 40, which includes a stretching mounting seat 41, a pull rod 42 and a compression spring 43.

The compression spring 43 is sleeved on the pull rod 42, and its two ends are respectively against the right side of the stretching mounting seat 41 and the right end of the pull rod 42. The elastic stretching component 40 can apply a rightward pulling force to the fixed component 20 on the right side of the base 10, thereby tightening and flattening the circuit board body 30, so that the installed circuit board will not be loose and shake, and will be more firm and reliable.

[0023] The circuit board 100 that is easy to fix and install also includes two groups of limit assemblies 50, which are symmetrically installed on the front and rear sides of the base 10, and include a limit mounting seat 51, an adjusting screw 52, ​​a limit plate 53 and an auxiliary sliding rod 54.

The limit assembly 50 can limit and fix the front and rear sides of the circuit board body 30, thereby avoiding the risk of loosening or even falling off of the circuit board due to external force vibration after installation.

[0024] The circuit board 100 that is easy to fix and install also includes a heat dissipation fan 60.

[0025] Specifically, in this embodiment, the left and right ends of the circuit board body 30 are rounded, so that the rounded ends can be inserted between the two clamping teeth of the fixing assembly 20 more easily and conveniently, greatly reducing the difficulty of installing the circuit board.

[0026] In summary, the beneficial effects of the utility model of a circuit board 100 that is easy to fix and install are: by designing a fixing component 20 that clamps and fixes the circuit board body 30 at both ends, the circuit board is easier and simpler to install, and the installation firmness of the circuit board can be ensured at the same time; the elastic stretching component 40 is designed to stretch and fix the circuit board body 30, which further improves the installation firmness of the circuit board; the limiting component 50 limits the circuit board body 30, which can effectively prevent the circuit board from loosening due to vibration after installation; by designing a heat dissipation fan 60 structure on the base 10, the heat dissipation efficiency of the circuit board during operation can be improved; and the chamfered corners at both ends of the circuit board body 30 are more convenient for plugging and clamping it with the fixing component 20; the utility model is highly practical and has a strong promotional significance.
