Description

Technical Field

[0001] The present invention relates to the technical field of proportional valve controllers, and in particular to a proportional valve controller with a communication interface. Background Art

[0002] A proportional valve is a control valve that can control fluid flow and pressure in proportion to an input signal. A proportional valve controller is a device used to control a proportional valve. It receives external control signals and converts these signals into current signals that can drive the proportional valve. The use of a proportional valve controller includes installing the controller and connecting the power supply, connecting the controller output to the proportional valve, integrating it with an external control system through a communication interface, setting the required control parameters such as flow and pressure set points, and finally starting the controller to achieve precise control of the proportional valve, thereby regulating the fluid flow and pressure in the hydraulic system.

[0003] However, proportional valve controllers are usually required to be installed in a dry, dust-free environment. If the humidity in the installation environment is too high or there is a lot of dust, it will affect the connection stability of the controller communication interface, resulting in communication failures or decreased controller performance. Summary of the invention

[0004] The present invention aims to provide a proportional valve controller with a communication interface to solve the problem in the prior art that high humidity or dust may affect the electrical performance of the proportional valve controller and the stability of the communication interface, resulting in failure or performance degradation.

[0009] A fixing structure is provided at the bottom of the above-mentioned cover plate, and the two ends of the above-mentioned fixing structure are movably connected to the above-mentioned synchronization components of the above-mentioned first containing box and the above-mentioned second containing box respectively. A plurality of square grooves arranged in a linear array are provided at the connection between the above-mentioned fixing structure and the above-mentioned cover plate, and the interiors of the plurality of the above-mentioned square grooves are provided with mutually symmetrical arc-shaped upper clamping blocks and arc-shaped lower clamping blocks.

[0010] When in use, the base is fixed on a stable working plane, and the operator lifts the cover plate, and the cover plate moves along the first receiving box and the second receiving box of the covering structure, and the fixed structure is synchronously separated from the cover plate through the synchronization components inside the first receiving box and the second receiving box, and the plurality of square grooves are split into two sections. When the staff connects the cables to the plurality of square grooves, the operator presses down the cover plate, and under the action of the synchronization components, the fixed structure and the cover plate are synchronously moved together, and then the cables are clamped by the arc-shaped upper clamping block and the arc-shaped lower clamping block, so as to prevent moisture and a large amount of dust from entering the interior of the cover plate along the holes of the plurality of square grooves.

[0011] The proportional valve controller with a communication interface disclosed in the present embodiment can conveniently cover the above-mentioned outer shell by using the above-mentioned covering structure, the above-mentioned first containing box, the above-mentioned second containing box, the above-mentioned cover plate and other components, effectively blocking moisture and dust in the environment from entering the interior of the controller, thereby improving the adaptability of the controller to harsh environments. The square groove design at the connection between the above-mentioned fixed structure and the above-mentioned cover plate can ensure that the communication interface can still maintain a stable connection in the covered state, avoiding communication failures caused by environmental humidity or dust, thereby enabling the proportional valve controller with a communication interface to prevent the intrusion of dust and moisture, ensure the stable connection of the communication interface, avoid communication failures caused by environmental humidity or dust, and improve the stability and performance of the controller.

[0012] Optionally, the first storage box and the second storage box are both provided with a mutually symmetrical first slide groove and a second slide groove in the inner axial direction, a first slider is slidably connected in the groove of the first slide groove, and the first slider is fixedly connected to the cover plate;

[0018] When the operator opens the cover plate, the operator pulls the cover plate upward along the first slide slot, and the first slider on the cover plate drives the first tooth plate to move upward in the guide space formed by the first guide plate. The movement of the first tooth plate drives the first circular gear to rotate clockwise, and the clockwise rotation of the first circular gear drives the second tooth plate to move downward in the guide space formed by the second guide plate. When cables are fixedly connected in the square grooves, the mechanical kinetic energy formed by the second tooth plate and the first circular gear will force the cables to fall off from between the cover plate and the fixed structure, which makes it easy for the operator to open the cover plate to maintain the communication interface. When the operator closes the cover plate, the operator presses the cover plate downward along the first slide groove, and the first slider on the cover plate drives the first tooth plate to move downward in the guide space formed by the first guide plate. The movement of the first tooth plate drives the first circular gear to rotate counterclockwise, and the counterclockwise rotation of the first circular gear drives the second tooth plate to move upward in the guide space formed by the second guide plate, so that the cable is automatically engaged at the connection between the cover plate and the fixed structure, and the upper arc block and the lower arc block cooperate to realize the automatic sealing of the connection between the cable and the square groove, thereby preventing the intrusion of dust and moisture and improving the stability and performance of the controller.

[0024] With such arrangement, the design of the roller facilitates the cable to enter or escape from the regional space formed by the first elastic strip and the second elastic strip. The design that the first elastic strip and the second elastic strip are colinear with the central axis of the opening and closing circle formed by the arc-shaped upper clamp and the arc-shaped lower clamp can ensure that the cable can be precisely aligned when fixed, avoiding unstable fixation or damage to the cable due to position deviation.

[0026] With such a configuration, the operator turns the knob, which drives the fixed shaft to rotate, and the fixed shaft drives the second circular gear to rotate. The rotation of the second circular gear can drive the third gear plate and the fourth gear plate on the second circular gear to move synchronously, thereby facilitating the locking of the cover plate on the housing to prevent the cover plate from being accidentally opened during use, thereby preventing the protection of the communication interface from being affected.
