Furthermore, existing fixing devices are also prone to instability during fixing. Therefore, improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing device for control circuit boards, which has the advantages of dual fixing and protection of control circuit boards, thus solving the problems mentioned in the background art.

[0006] As a preferred embodiment of this utility model, the fixing component includes a base block, an electric telescopic cylinder is fixedly installed on the top of the base block, a telescopic rod is slidably connected to the inner wall of the electric telescopic cylinder, a pressing rod is rotatably connected to the top of the telescopic rod, a fixing plate is fixedly mounted on the top of the electric telescopic cylinder, a limit handle is rotatably connected to the top of the fixing plate, and a contact plate is fixedly mounted on the outer wall of the pressing rod away from the fixing plate.

[0007] As a preferred technical solution of this utility model, there are eight sets of fixing components, and the eight sets of fixing components are evenly distributed on the outer wall of the circuit board body. The bottom of the base block is installed on the top of the base. The electric telescopic cylinder is electrically connected to the controller. The end of the limiting handle away from the fixing plate is rotatably connected to the outer wall of the lower pressure rod.

[0008] As a preferred embodiment of this utility model, the protective component includes a compression spring, a flexible rod is fixedly mounted on the top of the compression spring, and an electro-hydraulic rod is provided on the outer wall of the compression spring.

[0009] As a preferred embodiment of this utility model, there are several compression springs and flexible rods, and these compression springs and flexible rods are evenly distributed on the top of the partition. The electro-hydraulic rod is electrically connected to the controller, and the bottom of the electro-hydraulic rod is located on the top of the base. The bottom of the compression spring is fixedly installed on the top of the partition.

[0010] As a preferred embodiment of this utility model, the number of PCB spacers is four, and the bottoms of the four PCB spacers are evenly distributed on the inner wall of the partition. The PCB spacers are made of soft rubber, and the tops of the PCB spacers are conical.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The fixing device of the control circuit board, through the signal emitted by the controller, enables the electric telescopic cylinder to start working, allowing the telescopic rod to slide upward from the inner wall of the electric telescopic cylinder, thereby changing the angle of the downward pressing rod, which in turn allows the contact plate to contact the top of the circuit board body and fix the circuit board body. During the placement of the circuit board body, the PCB spacers are inserted into the inner wall of the circuit board body, and the PCB spacers provide double fixation for the circuit board body, making the fixing effect of the device better and preventing the circuit board body from shaking and affecting subsequent work.

[0013] 2. The fixing device for the control circuit board, by placing the circuit board body on top of the flexible rod, allows the unevenness of the circuit board body to push the flexible rod downwards, thus improving the protective effect of fixing the circuit board body. After the circuit board body has completed its work, the controller can send a signal to activate the electric hydraulic rod, which in turn lifts the circuit board body upwards, making it easier to remove the circuit board body. After the circuit board body is removed, the compression spring will release its elastic potential energy, causing the flexible rod to return to its original position, facilitating the next fixing of the circuit board body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 A fixing device for a control circuit board includes a support leg 1, a base 2 fixedly mounted on the top of the support leg 1, a controller 3 fixedly mounted on the top of the base 2, a fixing component 4 and a protective component 8 respectively provided on the top of the base 2, a partition 6 snapped onto the outer wall of the fixing component 4, a circuit board body 5 mounted on the top of the protective component 8, and a PCB spacer 7 snapped onto the inner wall of the circuit board body 5.

[0024] By utilizing the above structure and the setting of the support leg 1, the stability of the device can be guaranteed, so that the device will not easily shake when fixing the circuit board body 5.

[0025] In a preferred embodiment, the fixing component 4 includes a base block 401, an electric telescopic cylinder 402 is fixedly mounted on the top of the base block 401, a telescopic rod 403 is slidably connected to the inner wall of the electric telescopic cylinder 402, a pressing rod 404 is rotatably connected to the top of the telescopic rod 403, a fixing plate 405 is fixedly mounted on the top of the electric telescopic cylinder 402, a limit handle 406 is rotatably connected to the top of the fixing plate 405, and a contact plate 407 is fixedly mounted on the outer wall of the pressing rod 404 away from the fixing plate 405.

[0026] In a preferred embodiment, there are eight sets of fixing components 4, and the eight sets of fixing components 4 are evenly distributed on the outer wall of the circuit board body 5. The bottom of the base block 401 is installed on the top of the base 2. The electric telescopic cylinder 402 is electrically connected to the controller 3. The end of the limiting handle 406 away from the fixing plate 405 is rotatably connected to the outer wall of the pressing rod 404.

[0027] Using the above structure, the controller 3 can send a signal to enable the electric telescopic cylinder 402 to start working, and the telescopic rod 403 can slide upward from the inner wall of the electric telescopic cylinder 402, thereby causing the downward pressing rod 404 to change angle, and then the contact plate 407 can contact the top of the circuit board body 5, and can fix the circuit board body 5.

[0028] In a preferred embodiment, the protective component 8 includes a compression spring 801, a flexible rod 802 is fixedly mounted on the top of the compression spring 801, and an electro-hydraulic rod 803 is provided on the outer wall of the compression spring 801.

[0029] In a preferred embodiment, there are several compression springs 801 and flexible rods 802, and several compression springs 801 and flexible rods 802 are evenly distributed on the top of the partition 6. The electro-hydraulic rod 803 is electrically connected to the controller 3, and the bottom of the electro-hydraulic rod 803 is located on the top of the base 2. The bottom of the compression spring 801 is fixedly installed on the top of the partition 6.

[0030] Using the above structure, by placing the circuit board body 5 on top of the flexible rod 802, the unevenness of the circuit board body 5 will cause the flexible rod 802 to press downward, which can improve the protective effect of fixing the circuit board body 5. After the circuit board body 5 has completed its work, the controller 3 can send a signal to start the electric hydraulic rod 803, which can then drive the circuit board body 5 upward to complete the lifting work, thereby making it easier to remove the circuit board body 5.

[0031] In a preferred embodiment, there are four PCB spacers 7, and the bottoms of the four PCB spacers 7 are evenly distributed on the inner wall of the partition 6. The PCB spacers 7 are made of soft rubber, and the tops of the PCB spacers 7 are conical.

[0032] By utilizing the above structure, and through the setting of the PCB spacer 7 and the characteristic that the PCB spacer 7 is made of soft rubber, the PCB spacer 7 can be quickly installed and removed, thereby effectively avoiding a lot of time wasted in the process of tightening and removing screws.

[0033] Working principle: When using this device, the circuit board body 5 to be fixed is placed on top of the electro-hydraulic rod 803, allowing the PCB spacer 7 to penetrate the inner wall of the circuit board body 5 and fix the circuit board body 5. A signal is transmitted via the controller 3 to activate the electric telescopic cylinder 402, allowing the telescopic rod 403 to slide upwards from the inner wall of the electric telescopic cylinder 402. This causes the downward pressure rod 404 to change angle, allowing the contact plate 407 to contact the top of the circuit board body 5 and thus fix the circuit board body. 5 plays a fixing role. During this process, the circuit board body 5 will cause the flexible rod 802 to drive the compression spring 801 to press downward due to its own weight and the unevenness of the surface of the circuit board body 5. This allows several flexible rods 802 to protect the circuit board body 5. After the circuit board body 5 has completed its work, the controller 3 can send a signal to start the electric hydraulic rod 803, which can then drive the circuit board body 5 upward to complete the lifting work, making it easy to remove the circuit board body 5. After removal, the flexible rod 802 will automatically reset due to the compression spring 801.
