Description

Technical Field

[0001] This utility model relates to lithium-ion electric drills, and more particularly to a multifunctional lithium-ion electric drill, belonging to the field of electric drill mechanical design technology. Background Technology

[0002] In many fields, electric drills, as a basic and crucial power tool, are widely used in various drilling and fastening operations.

[0003] Publication number CN202943300U discloses an electric drill, including a drill body, a power cord, and a drill key. The drill key has a through hole at its tail end. The drill also includes a cable tie, which is wrapped around the power cord and passes through the through hole to secure it. With this structure, the electric drill has the following advantages: 1. The cable tie can secure the drill key to the power cord, preventing the key from falling off after use; 2. The flattened head of the drill key facilitates the passage of the cable tie.

[0004] Currently, handheld lithium-ion electric drills have significant functional limitations in practical applications. First, the sawdust, plaster, and other debris generated during operation are dispersed and suspended in the air, not only degrading air quality in the construction environment and severely affecting workers' vision and respiratory health, but also potentially leading to occupational diseases such as pneumoconiosis with prolonged exposure. Simultaneously, these dust particles can penetrate the drill's interior, accelerating wear on the motor and transmission components and reducing the equipment's lifespan. Second, in ceiling-mounted or high-altitude work scenarios, traditional electric drills rely on single-handed operation. When the drill needs to be lifted for drilling, its weight and the reaction force generated by the operation concentrate on the operator's arm muscles, quickly leading to soreness and fatigue. Furthermore, single-handed grip lacks a stable point of leverage, making it difficult to maintain precise positioning of the drill during operation, easily causing drilling position deviation and affecting accuracy.

[0005] Furthermore, when drilling into high-strength materials such as concrete and stone, operators often need to hold the drill with both hands and apply force towards the drill bit. However, the high-frequency vibrations generated by the electric drill are transmitted to the human body without any buffering. Prolonged exposure to this working condition can not only cause severe soreness in the operator's shoulders, hands, and other contact areas, but may also lead to chronic injuries such as vibration sickness, significantly reducing work efficiency and operator comfort.

[0006] Therefore, a multi-functional lithium-ion electric drill is proposed. Utility Model Content

[0007] In view of this, the present invention provides a multi-functional lithium-ion electric drill to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0008] The technical solution of this utility model is implemented as follows: A multifunctional lithium-ion electric drill includes a drill body, a drill bit installed at the output end of the drill body, a support plate installed below the drill body, a guide rod slidably installed inside the support plate, a collection cavity installed at one end of the guide rod, a spring A sleeved on the guide rod, a material guiding cavity connected to the collection cavity, a collection hopper connected to the material guiding cavity, a rotating shaft rotatably installed inside the collection cavity, a ventilation plate installed on the rotating shaft, a filter element provided on the ventilation plate, an opening and closing plate provided inside the collection cavity, a handle installed at one end of the rotating shaft, a positioning groove provided on the collection cavity, a positioning bolt threaded onto the handle, and an air pump installed on the back of the support plate, with a flexible hose connected to the air pump's suction end.

[0014] More preferably, the top pressure plate is slidably disposed in the movable block, and the top pressure plate can slide in the vertical direction within the movable block, and the top pressure plate is provided with anti-slip protrusions.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model achieves efficient collection and convenient handling of drilling dust through its dust collection mechanism. During operation, the air pump quickly draws air from the collection chamber to create negative pressure. Combined with the optimized design of the material guide chamber, it can quickly suck in sawdust, wall plaster, and other dust generated during drilling into the collection chamber. This effectively improves the air quality of the construction environment, protects the respiratory health of operators, and prevents dust from entering the electric drill, reducing wear on the motor and transmission components and extending the equipment's service life. Furthermore, the filter element can be easily replaced simply by rotating the shaft. Simultaneously, the rotation of the shaft moves the old filter element and collected debris down to the bottom of the collection chamber. By opening and closing the switch plate, impurities can be quickly removed, effectively improving the continuity and efficiency of drilling operations.

[0017] Second, this utility model combines flexibility and comfort by incorporating a detachable tailplate. The tailplate can be quickly assembled and disassembled according to different work scenarios, adapting to diverse working environments. The buffer mechanism at the tail support effectively absorbs and disperses the high-frequency vibrations generated during electric drilling. In high-intensity operations such as concrete drilling, this buffer structure significantly reduces the intensity of vibration transmission along the machine body to the human body, not only reducing the risk of occupational injuries such as vibration sickness and muscle strain, but also greatly improving the comfort of long-term work and protecting the health of operators.

[0018] Thirdly, this utility model features an adjustable grip that can be flexibly installed on the bottom or sides of the electric drill to meet the gripping habits and operational needs of different operators. During adjustment, the grip position can be precisely positioned and securely locked by rotating the threaded rod below; the operation is simple and requires no additional tools. This flexible and adjustable structural design effectively improves the operator's grip stability and comfort, and significantly enhances the accuracy and convenience of electric drill operation in scenarios such as ceiling work.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-7As shown, this utility model embodiment provides a multifunctional lithium-ion electric drill, including a drill body 1, a drill bit 2 installed at the output end of the drill body 1, a support plate 3 installed below the drill body 1, a guide rod 4 slidably installed inside the support plate 3, a collection chamber 5 installed at one end of the guide rod 4, a spring A6 sleeved on the guide rod 4, a material guiding chamber 7 connected to the collection chamber 5, a collection hopper 8 connected to the material guiding chamber 7, a rotating shaft 9 rotatably installed inside the collection chamber 5, a ventilation plate 10 installed on the rotating shaft 9, a filter element 11 provided on the ventilation plate 10, an opening and closing plate 12 provided inside the collection chamber 5, a handle 13 installed at one end of the rotating shaft 9, a positioning groove 14 provided on the collection chamber 5, a positioning bolt 15 threadedly connected to the handle 13, and an air pump 16 installed on the back of the support plate 3, with a hose 17 connected to the air extraction end of the air pump 16.

[0032] In one embodiment, one end of spring A6 is mounted on support plate 3, and the other end of spring A6 is mounted on collection chamber 5. As the borehole deepens, collection hopper 8, guide chamber 7, collection chamber 5, and guide rod 4 move backward along support plate 3, compressing spring A6 in the process.

[0033] In one embodiment, the collecting hopper 8 is wrapped around the drill bit 2, and the hose 17 is connected to the collecting chamber 5. When the electric drill body 1 starts drilling, the collecting hopper 8 surrounds the drill bit 2 and fits against the working surface. The air pump 16 draws air from the collecting chamber 5 through the hose 17 to create negative pressure, and the dust is sucked in through the guide chamber 7.

[0034] In one embodiment, a T-shaped slot 34 is provided on the back of the drill body 1, and a T-shaped plug 18 adapted thereto is inserted into the T-shaped slot 34. A tail plate 19 is connected to the back of the T-shaped plug 18. A limit plate 20 is rotatably installed on the drill body 1. A telescopic rod 25 is installed on the back of the tail plate 19. A tail support 23 is installed on the back of the telescopic rod 25. A spring B26 is sleeved on the telescopic rod 25. A left-right sliding groove is provided in the tail support 23. A slider 22 adapted thereto is slidably installed in the sliding groove. A connecting plate 21 is hinged to the slider 22. The connecting plate 21 is hinged to the tail plate 19. A tension spring 24 is provided on the connecting plate 21. During operation, vibration compresses spring B26, while slider 22 in tail support 23 slides in the groove. Connecting plate 21 drives tension spring 24 to extend and retract. In high-intensity operations such as concrete drilling, this buffer structure can significantly reduce the intensity of vibration transmission from the machine body to the human body. This not only reduces the risk of occupational injuries such as vibration sickness and muscle strain, but also greatly improves the comfort of long-term operation and protects the health of operators.

[0035] In one embodiment, spring B26 is disposed between tail support 23 and tail plate 19, and tension spring 24 is connected between two sets of adjacent connecting plates 21. Vibration is absorbed by spring B26 and the connecting rod structure, reducing the transmission of vibration to the human body.

[0036] In one embodiment, a guide rail 27 is mounted on the tail plate 19, a top groove 28 is provided in the guide rail 27, a movable block 29 is slidably mounted in the guide rail 27, a handle 30 is mounted below the movable block 29, a threaded seat 31 is mounted below the handle 30, a threaded rod 32 is threadedly connected to the threaded seat 31, and a top pressure plate 33 is rotatably mounted above the threaded rod 32. When adjusting the handle 30, the movable block 29 slides on the guide rail 27 of the tail plate 19 to the desired position, and then the threaded rod 32 is rotated, causing the top pressure plate 33 to press against the top groove 28 in the guide rail 27 and apply top pressure.

[0037] In one embodiment, the top pressure plate 33 is slidably disposed within the movable block 29, and the top pressure plate 33 can slide vertically within the movable block 29. The top pressure plate 33 is provided with anti-slip protrusions. The anti-slip protrusions can effectively enhance the fixing effect.

[0038] When this utility model is in operation: when the electric drill body 1 starts drilling, the collection bucket 8 surrounds the drill bit 2 and fits against the working surface. The air pump 16 draws air into the collection chamber 5 through the hose 17 to form a negative pressure. Dust is sucked in through the guide chamber 7. As the drilling goes deeper, the collection bucket 8, the guide chamber 7, the collection chamber 5 and the guide rod 4 will move backward along the support plate 3. In this process, the spring A6 is squeezed. During this process, the filter element 11 will filter the dust. When it is necessary to discharge impurities, first turn the handle 13 to make the old filter element 11 move the debris down to the bottom of the collection chamber 5. Then open the opening and closing plate 12 to discharge the impurities, realizing the collection and cleaning of dust. At the same time as the rotating shaft 9 rotates, it will drive the new filter element 11 to the position. Tighten the positioning bolt 15 to fix it, and then the filter element 11 is replaced. When installing the tailplate 19, insert the T-shaped insert 18 into the T-shaped slot 34 of the drill body 1, and lock it by rotating the limit plate 20. The tail support 23 is connected to the tailplate 19 through the telescopic rod 25. The spring B26 is sleeved on the telescopic rod 25. During operation, vibration causes the spring B26 to compress, and at the same time, the slider 22 in the tail support 23 slides in the groove. The connecting plate 21 drives the tension spring 24 to extend and retract. The vibration is absorbed by the spring B26 and the connecting rod structure, reducing the transmission of vibration to the human body. When adjusting the handle 30, the moving block 29 slides on the guide rail 27 of the tailplate 19 to the desired position. Then, the threaded rod 32 is rotated, and under the action of the thread, the top pressure plate 33 is pressed against the top groove 28 in the guide rail 27 and a top pressure is applied. The anti-slip convex strip enhances the fixing effect, thereby locking the handle 30 at the bottom or both sides to meet different grip requirements and ensure stable operation.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
