Description

Technical Field

[0001] This utility model relates to the field of industrial flat panel technology, specifically a waterproof and dustproof touch screen device. Background Technology

[0002] Waterproof and dustproof touchscreen devices are specially designed touch instruments to resist the intrusion of moisture, dust, and other contaminants, ensuring normal operation even in harsh environments. These devices typically employ special sealing structures and material processes and are certified to international protection standards. Their core function is to ensure the stability and durability of electronic devices while maintaining touch sensitivity and display clarity. Existing industrial tablets often incorporate magnetic flip covers at peripheral interfaces to adapt to complex workshop environments, preventing moisture and dust from entering when not in use.

[0003] While adding a magnetic flip cover to the peripheral interface improves protection and ease of operation, it may loosen or become stuck after prolonged use, reducing the effectiveness of the seal. In the event of a drop or severe vibration, the flip cover may pop open, rendering it ineffective. Furthermore, an open flip cover can exert pressure on the cables. Therefore, a waterproof and dustproof touchscreen device is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof and dustproof touchscreen device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a waterproof and dustproof touch screen device, comprising: An industrial flat panel includes a housing, a display screen, a peripheral interface, and a waterproof and dustproof cover. The display screen is fixed to the middle of one side of the housing, the peripheral interface is opened at one end of the housing, and the waterproof and dustproof cover is hinged to one end of the housing and covers the peripheral interface. The limiting component includes a fixing block, a slot, a support plate, a spring, and a limiting block. The fixing block is fixed to one end of the housing and located between two peripheral interfaces. The slot is opened at both ends of the fixing block. The support plate is fixed in the middle of the slot. One end of the spring is fixed to the side of the support plate and located in the slot. The limiting block is fixed to the other end of the spring.

[0005] Furthermore, the limiting component also includes a pull plate, which is fixed above the limiting block at one end near the support plate.

[0006] Furthermore, the limiting component also includes an opening, which is formed on the bottom surface of the slot.

[0007] Furthermore, the lower end of the limiting block away from the support plate is arc-shaped, and the limiting block is movably connected within the slot.

[0008] Furthermore, it also includes a contact assembly, which includes a groove, a connecting shaft, an extension plate, and a limiting plate. The groove is formed on the upper end of the pull plate, the connecting shaft is fixed inside the groove, the limiting plate is fixed on one side of the groove, and one end of the extension plate is sleeved on the connecting shaft.

[0009] Furthermore, the contact assembly also includes a torsion spring, which is sleeved on both ends of the connecting shaft, with one end fixed to the side of the extension plate and the other end fixed to the side of the groove.

[0010] Furthermore, when the waterproof and dustproof cover is opened, the limiting block is located at the lower end of the waterproof and dustproof cover.

[0011] This utility model has the following beneficial effects: This invention utilizes a limiting component. Pulling the waterproof and dustproof cover upwards causes the limiting block to move inwards along the slot within the fixed block. When the waterproof and dustproof cover is fully open, the spring on the side of the support plate extends, causing the limiting block to move outwards. One end of the limiting block moves to the lower end of the waterproof and dustproof cover. After use, pulling the pull plate moves the limiting block into the slot, causing the waterproof and dustproof cover to automatically flip downwards and fit against the external interface. Releasing the pull plate resets the limiting block, keeping it firmly against the outer edge of the waterproof and dustproof cover. Dust that falls into the slot will fall out through the opening. This design forms a physical lock, preventing the cover from accidentally popping open when the device is dropped or vibrated, effectively maintaining the seal at the interface, avoiding the risk of cable compression caused by traditional flip covers, and preventing cable bending damage.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a waterproof and dustproof touch screen device, comprising: An industrial flat panel includes a housing 10, a display screen 11, a peripheral interface 12, and a waterproof and dustproof cover 13. The display screen 11 is fixed to the middle of one side of the housing 10, the peripheral interface 12 is opened at one end of the housing 10, and the waterproof and dustproof cover 13 is hinged to one end of the housing 10 and covers the peripheral interface 12. The industrial tablet model Advantech UNO-2170E has a housing 10 that provides support and protection. The display screen 11 is a resistive touchscreen that operates by pressure sensing. The outer layer is made of plastic and has good dust and water resistance. It supports touch operation on any object. The peripheral interface 12 is used to connect cables and connect to external devices. The waterproof and dustproof cover 13 is a magnetic flip cover.

[0018] The limiting component includes a fixing block 20, a slot 21, a support plate 22, a spring 23, and a limiting block 24. The fixing block 20 is fixed to one end of the housing 10 and is located between the two peripheral interfaces 12. The slot 21 is opened at both ends of the fixing block 20. The support plate 22 is fixed in the middle of the slot 21. One end of the spring 23 is fixed to the side of the support plate 22 and is located in the slot 21. The limiting block 24 is fixed to the other end of the spring 23. The limiting component also includes a pull plate 25, which is fixed above the limiting block 24 at one end near the support plate 22; The limiting component also includes an opening 26, which is formed on the bottom surface of the slot 21; The lower end of the limiting block 24 away from the support plate 22 is arc-shaped, and the limiting block 24 is movably connected in the slot 21; When the waterproof and dustproof cover 13 is opened, the limiting block 24 is located at the lower end of the waterproof and dustproof cover 13; The fixing block 20 provides support, the slot 21 facilitates the installation of the spring 23 and the limiting block 24, the support plate 22 provides support, the spring 23 has a telescopic function, the limiting block 24 provides a limit, the pull plate 25 facilitates the movement of the limiting block 24, and the opening 26 facilitates the discharge of dust from the slot 21.

[0019] Working principle: Pull the waterproof and dustproof cover 13 upwards, causing the limiting block 24 to move inwards along the slot 21 in the fixing block 20. When the waterproof and dustproof cover 13 is fully opened, the spring 23 on the side of the support plate 22 extends, causing the limiting block 24 to move outwards. One end of the limiting block 24 moves to the lower end of the waterproof and dustproof cover 13. After use, pull the pull plate 25, causing the limiting block 24 to move into the slot 21. The waterproof and dustproof cover 13 automatically flips downwards and fits onto the peripheral interface 12. Release the pull plate 25, and the limiting block 24 resets and fits tightly against the outer side of the waterproof and dustproof cover 13. The dust that falls into the slot 21 will fall out from the opening 26.

[0020] This step creates a physical lock, preventing the cover from accidentally popping open when the device is dropped or vibrated, effectively maintaining the seal at the interface, avoiding the risk of cable compression caused by traditional flip covers, and preventing cable bending damage.

[0021] Please see Figure 3 As shown, this embodiment, based on the above embodiment, further includes: The contact assembly includes a groove 30, a connecting shaft 31, an extension plate 33, and a limiting plate 34. The groove 30 is opened at the upper end of the pull plate 25, the connecting shaft 31 is fixed inside the groove 30, the limiting plate 34 is fixed on one side of the groove 30, and one end of the extension plate 33 is sleeved on the connecting shaft 31. The contact assembly also includes a torsion spring 32, which is sleeved on both ends of the connecting shaft 31, with one end fixed to the side of the extension plate 33 and the other end fixed to the side of the groove 30. The groove 30 is used to fix the connecting shaft 31, which facilitates the rotation of the extension plate 33. The torsion spring 32 has a reset function, the extension plate 33 facilitates the hand movement of the pull plate 25, and the limiting plate 34 plays a limiting role.

[0022] Working principle: After the peripheral interface 12 is finished, the finger moves the extension plate 33, causing it to rotate around the connecting shaft 31 in the groove 30 and be restricted by the limiting plate 34. The extension plate 33 continues to move, causing the pull plate 25 to move, which in turn causes the limiting block 24 to move into the slot 21. When the limiting block 24 is removed from the lower end of the waterproof and dustproof cover 13, the waterproof and dustproof cover 13 automatically flips and merges into the peripheral interface 12. The extension plate 33 is released, the limiting block 24 is reset and fits against the outer side of the waterproof and dustproof cover 13. Under the action of the torsion spring 32, the extension plate 33 rotates in the opposite direction around the connecting shaft 31 and is parallel to the fixing block 20.

[0023] This step facilitates hand operation of the pull plate 25 and prevents the pull plate 25 from being too long, which would affect the comfort of use.
