Description

Technical Field

[0001] This utility model relates to the field of screen display testing technology, and in particular to a front-end movable magnetic structure. Background Technology

[0002] For numerous industrial production, scientific research experiments, and everyday electronic device applications, a structure that allows for convenient and quick adjustment of the position of front-end components while possessing good stability and reliability is crucial. In this context, a movable, magnetically attached front-end structure has emerged, offering a novel approach and solution to the operational challenges of front-end components in many devices.

[0003] In related fields, common mechanical structures for moving and fixing components often employ a combination of rails and screws for fastening. By setting rails on a fixed bracket, a slider at the bottom of the component moves by embedding itself in the rails. Once the component reaches the designated position, screws are passed through pre-drilled holes in the slider and tightened onto the bracket, thus achieving fixation. This technology is primarily based on mechanical sliding and fastening, ensuring that the component can change position within a certain range and remain stable.

[0004] However, this traditional mechanical structure reveals inconvenience in installation and disassembly during practical applications. In real-world scenarios, when frequent adjustments to component positions are required, the use of screws necessitates multiple tightening operations with tools for each installation and disassembly, a cumbersome and time-consuming process. This not only reduces work efficiency but can also lead to damage such as stripped screws due to repeated operations, further affecting the normal use of the equipment and severely limiting the work process, failing to meet the demands of modern fast-paced, high-efficiency production and operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a front-end movable magnetic structure, which aims to improve the problem that the existing structure is not convenient to install and disassemble in practical applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front-end movable magnetic suction structure, including a motherboard, a connecting plate fixedly connected to the lower surface of the motherboard, a support block fixedly connected to the upper surface of the motherboard, a telescopic rod fixedly connected to the inner wall of the support block, a spring fixedly connected to the outer wall of the telescopic rod, a connecting block fixedly connected to the outer wall of the spring, a rubber block fixedly connected to the outer wall of the connecting block, and a fixing component provided on the inner wall of the motherboard;

[0007] The fixing component includes a magnet, the outer wall of which is fixedly connected to the inner wall of the main board. The inner wall of the main board has a sliding groove. A guide rail is fixedly connected to the upper surface of the main board. An iron block is slidably connected to the outer wall of the magnet. A slider is fixedly connected to the outer wall of the iron block. A bolt is threadedly connected to the inner wall of the slider. A fixing groove is provided on the inner wall of the slider.

[0008] Furthermore, a connecting plate is fixedly connected to the upper surface of the motherboard, a pin is rotatably connected inside the motherboard, a fixing block is fixedly connected to the outer wall of the pin, and a slot is opened inside the motherboard.

[0009] Furthermore, the outer wall of the magnet is fixedly connected to the inner wall of the groove, and the magnet is used to fix the iron block.

[0010] Furthermore, the outer wall of the bolt is threaded onto the inner wall of the main board, and the bolt is used to fix the slider.

[0011] Furthermore, the inner wall of the slider is provided with a connecting groove, which is used to install the test pressure head.

[0012] Furthermore, a reinforcing plate is fixedly connected to the lower surface of the motherboard, which serves to enhance the overall stability of the motherboard.

[0013] Furthermore, the outer wall of the telescopic rod is fixedly connected to the outer wall of the connecting block, and the telescopic rod is used to guide the movement of the spring.

[0014] Furthermore, the outer wall of the pin is rotatably connected to the inner wall of the slot, and the pin is used to fix the motherboard.

[0015] This utility model has the following beneficial effects:

[0016] 1.

After the slider with embedded iron blocks is moved to the use position, the fixing groove opened inside the slider allows it to be locked with bolts. Through the magnetic attraction between the magnets and the iron blocks, and the use of bolts for locking, the slider can be more easily installed and disassembled, improving the on-site installation efficiency.

[0017] 2. In this utility model, the motherboard is equipped with a pin, and an indicator is displayed on the connection plate, thereby assisting the operator in fixing the motherboard. Through the cooperation of the pin and the fixing block, the motherboard can be quickly installed on or removed from the equipment, thereby improving the customer's replacement efficiency.

By rotating the pin 2 to the corresponding position, the motherboard 1 can be quickly installed on or removed from the device.

[0028] Working Principle: When using the front-end movable magnetic detection component, magnets 3 are installed on both sides of the front of the main board 1. The iron block 11 is then attached to the magnets 3, allowing the slider 6 with the embedded iron block 11 to move manually within a range of 0-470mm. The guide rail 5 on the main board 1 guides the movement of the slider 6, ensuring it moves along a preset path and preventing deviation from the predetermined trajectory, thus guaranteeing accuracy and stability. After the slider 6 with the embedded iron block 11 is moved to the desired position, it is locked with locking bolts 14, thus fixing the slider 6. A connecting groove 10 is provided at the front of the slider 6, allowing the installation of a test pressure head. A connecting plate 8 is installed on the lower surface of the main board 1, thus... To facilitate the installation and testing of the PCB board, the pin 2 installed inside the motherboard 1 is rotated, allowing for quick installation or removal from the equipment. This improves customer replacement time and efficiency. The telescopic rod 17 is fixedly connected to the inner wall of the support block 7 and the outer wall of the connecting block 19. A spring 18 and a rubber block 20 are also fixedly connected to the outer wall of the connecting block 19. When the slider 6 collides or is impacted by external force during movement, it may come into contact with the rubber block 20. At this time, the rubber block 20 and the connecting block 19 will move under the guidance of the telescopic rod 17, and the spring 18 will be compressed, thus providing a buffering effect. The spring 18 absorbs some energy, reducing the impact on the entire structure and preventing damage to components, thereby ensuring the stability and service life of the structure.
