Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a high-sealing pressure-stabilizing blank seat. Background Art

[0002] A voltage stabilizer is a device designed to automatically maintain a constant voltage in electronic engineering. The voltage stabilizer is a rectangular box made of metal. It consists of a voltage regulating circuit, a control circuit, a servo motor, etc. It is mainly used to adjust the voltage, that is, to control the power supply voltage with large current fluctuations that cannot meet the requirements of electrical equipment within its set value range, so that each circuit or electrical equipment can work normally at the rated working voltage. The main types of voltage stabilizers include switching regulators, linear regulators, etc. Voltage stabilizers are an indispensable part of automotive circuits.

[0003] However, in the existing equipment, the base and the upper cover of the voltage stabilizer are connected by screws, which is not only difficult to disassemble and assemble, but also has poor sealing. Rainwater can easily enter the equipment through the gaps in the bolt connections, causing short-circuit damage to the equipment. Therefore, a high-sealing voltage stabilizer blank seat is proposed.

[0010] As a further description of the above technical solution:

[0011] The locking structure includes an insert plate fixedly connected to the upper cover, a storage hole is provided on one side of the insert plate, a spring is fixed in the storage hole, a push rod is fixed at one end of the spring, one end of the push rod is arc-shaped, and the arc-shaped end of the push rod is adapted to the arc groove and the positioning hole.

[0012] As a further description of the above technical solution:

[0013] A guide plate is fixedly arranged between the spring and the push rod, and the guide plate is in contact with the inner wall of the receiving hole.

[0014] As a further description of the above technical solution:

[0015] Two blocking pieces are arranged on one side of the plug board, and the two blocking pieces are distributed on both sides of the storage hole.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the high-sealing pressure-stabilizing blank seat can ensure the sealing between the upper cover and the base by setting a sealing gasket, which can effectively prevent liquid from entering the inside of the equipment through the gap. The drainage groove is located on the periphery of the placement groove. Therefore, when rainwater seeps in from the gap between the upper cover and the base, it will flow into the drainage groove and finally be discharged from the drainage hole, which can realize the drainage function of the equipment, improve the sealing of the equipment, and effectively prevent moisture from entering the inside of the equipment and causing short-circuit damage to the equipment.

[0018] 2. Compared with the prior art, the high-sealing pressure-stabilizing blank seat is provided with arc grooves, positioning holes, plug holes, storage holes, plug plates and push rods. When the upper cover needs to be removed, the multiple push rods are first squeezed inward, and the push rods then squeeze the springs. When the arc end of the push rod is retracted into the arc groove, the upper cover is pulled upward, and the upper cover drives the multiple plug plates to move up. One end of the push rod fits with the inner wall of the arc groove. When the plug plate is completely out of the slot, the disassembly of the upper cover is completed, replacing the traditional bolt positioning mode. It can not only improve the disassembly and assembly efficiency, but also reduce the setting of hole positions, reduce the intrusion of rainwater, and improve the sealing performance of the equipment.
