Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to a waterproof and dustproof processing structure of a one-button starting switch for a micro excavator. Background Art

[0002] An excavator is a type of engineering machinery widely used in earthwork construction. A bucket is provided on the front side of the excavator, and the bucket is connected to the excavator through a boom and an arm. A boom cylinder for controlling the movement of the arm is installed on the upper part of the boom. In addition, a boom cylinder for controlling the movement of the boom is also installed on the excavator. The boom cylinder is supplied with oil through the boom lifting oil circuit, and the boom lifting and falling are controlled by the boom cylinder; the movement of the bucket is controlled by the rocker arm cylinder, which is supplied with oil through the bucket retracting oil circuit, and the rocker arm rotation is controlled by the rocker arm cylinder, driving the bucket to complete the retracting and digging actions.

[0003] At present, the waterproof and dustproof levels of the one-button start switch on the excavator are low and cannot meet safety requirements. During use, if dust enters the switch, it will cause the switch button to get stuck and the function to fail. If water enters, it will cause a short circuit in the circuit, resulting in abnormal function or burning. This needs to be improved. Utility Model Content

[0004] The utility model aims to provide a waterproof and dustproof structure of a one-touch start switch for a micro excavator with high safety in view of the above problems.

[0005] To achieve the above-mentioned purpose, the utility model discloses a waterproof and dustproof treatment structure of a one-button start switch for a micro excavator, including a shell, and its structural characteristics are: a button that can be raised and lowered is slidably installed in the shell, a positioning sleeve is provided on the upper edge of the shell, the inner side wall of the positioning sleeve extends downward and extends into the gap between the shell and the button, the outer side wall of the positioning sleeve extends downward to the outside of the shell, the upper part of the shell is covered with a silicone sleeve, the outer edge of the silicone sleeve extends downward and is clamped on the lower edge of the outer wall of the positioning sleeve.

[0006] The design of the positioning sleeve cleverly extends the inner wall into the gap between the housing and the button, effectively blocking the entry path of moisture and dust, and providing a more comfortable and stable touch. The silicone sleeve covers the upper part of the housing, and its softness and sealing provide an additional waterproof and dustproof barrier to ensure that the switch can work stably in harsh environments. The combination of the positioning sleeve and the silicone sleeve makes the overall structure more stable, reducing the risk of structural loosening or damage due to external shock or vibration. This waterproof and dustproof treatment structure of the one-button start switch for micro-excavation not only has excellent waterproof and dustproof performance, but also has the advantages of stable structure, smooth operation, good user experience, and easy installation and maintenance, providing a strong guarantee for the safe and stable operation of micro-excavation equipment.

[0007] Preferably, the positioning sleeve is in a circular shape and surrounds the upper edge of the shell. This design allows the positioning sleeve to evenly cover the upper edge of the shell, thereby enhancing the overall stability and structural strength. The circular design also makes the positioning sleeve easier to manufacture and install, thereby improving production efficiency.

[0008] Preferably, a mounting sleeve is installed on the outside of the housing, an external thread is provided on the outer wall of the housing, a corresponding internal thread is provided on the inner wall of the mounting sleeve, and the mounting sleeve is screwed onto the housing. This design allows the switch to be conveniently installed and fixed on the micro-excavation equipment, improving the flexibility and convenience of installation. The cooperation of the external thread and the internal thread makes the connection between the mounting sleeve and the housing more firm and reliable, not easy to loosen, and can also adjust the installation height of the housing.

[0009] Preferably, a spring is installed in the shell to push the button upward. The design of the spring enables the button to automatically return to its original position when not pressed, ensuring the normal working state of the switch. The elastic force of the spring can be adjusted as needed to make the pressing and popping actions of the button smoother and more stable.

[0010] Preferably, a boss is provided on the inner wall of the shell, the lower end of the spring is pressed against the boss, and the upper end of the spring is pressed against the lower part of the key. The design of the boss provides a stable support point for the spring, so that the elastic force of the spring can act evenly on the key, thereby improving the stability of the key.

[0011] Preferably, a layout area for accommodating electronic components is provided inside the housing, and the special layout area design enables the electronic components to be installed in an orderly manner inside the housing, thereby improving the overall compactness of the structure and the rationality of the layout. This design is also conducive to the heat dissipation and protection of the electronic components, and improves the working performance and reliability of the switch.

[0012] Preferably, a top edge is provided on the upper part of the housing, the top edge extends outward, and the lower end of the outer wall of the positioning sleeve is clamped on the lower part of the top edge. The design of the top edge provides additional support and fixing points for the positioning sleeve, thereby enhancing the connection stability between the positioning sleeve and the housing. This structure also allows the positioning sleeve to be more firmly fixed on the housing, preventing the positioning sleeve from loosening or falling off due to external impact or vibration.

[0013] Preferably, the electronic components inside the housing are covered with a waterproof adhesive layer: the design of the waterproof adhesive layer effectively isolates the electronic components from the external environment, preventing moisture and dust from corroding and damaging the electronic components. This treatment method improves the waterproof and dustproof performance of the electronic components and extends the service life and reliability of the switch.

[0014] Preferably, a through hole is provided on the side wall of the housing, which passes through the housing and is located at the lower part of the housing, at the uppermost edge of the waterproof adhesive layer of the electronic component, wherein the micro switch in the electronic component is covered with a separate silicone sleeve, which is dustproof and waterproof and does not affect the up and down movement of the micro switch. The through hole can ensure the balance of air pressure in the switch cavity during the process of pressing and rebounding the key, ensuring smooth pressing; it can also ensure that water that enters the switch cavity after aging and damage of the upper silicone sleeve is discharged in time.

[0015] To sum up, the beneficial effects of the utility model are that the solution not only has excellent waterproof and dustproof performance, but also has the advantages of stable structure, smooth operation, good user experience, and easy installation and maintenance, which provides a strong guarantee for the safe and stable operation of micro-excavation equipment.
