Description

Technical Field

[0001] This utility model relates to the field of cordless drills with protective structures, specifically a cordless drill with a protective structure. Background Technology

[0002] A cordless drill is a portable power tool powered by a lithium battery, freeing users from the constraints of a cord. It is suitable for drilling, screwing, and other similar tasks. Its lightweight body, coupled with multiple torque settings, allows it to work with various materials, including wood, metal, and plastic. The high-efficiency motor and fast-charging technology balance power and battery life. When using it, take precautions, especially as the high-speed rotation generates debris that can easily fly and cause injury. Wear safety goggles, keep the work area clean, and avoid debris buildup that could lead to slips or secondary splashes.

[0003] Since most existing cordless drills do not have a dust and debris protection function, users need to wear protective tools or be extra careful when using them, resulting in a poor user experience. Moreover, most devices do not have a support and positioning effect, making it easy to drill at an angle or deviate from the target point, which is not conducive to use. Utility Model Content

[0004] The purpose of this invention is to provide a rechargeable drill with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rechargeable drill with a protective structure, comprising a charging box, a drill body disposed on the upper side of the charging box, and a drill bit fixedly connected to one side of the drill body, wherein a support and positioning mechanism is disposed on the outer side of the drill bit, and a protective mechanism is disposed on the upper side of the drill body;

[0006] The support and positioning mechanism includes a slide cylinder, which is fixedly connected to one side of the drill body. A sliding plate is slidably connected inside the slide cylinder. A support rod is fixedly connected to the side of the sliding plate away from the drill body. The support rod is slidably connected inside the slide cylinder. A spring is fixedly connected between the side of the sliding plate away from the support rod and the inner wall of the slide cylinder. A sleeve is rotatably connected to the outer wall of the drill bit. A support is fixedly connected to the upper end of the sleeve. The support is located at the left end of the sleeve and is fixedly connected to the support rod. A scale support plate is fixedly connected to the outer side of the sleeve.

[0013] Compared with the prior art, this utility model provides a cordless drill with a protective structure, which has the following beneficial effects:

[0014] The protective mechanism is used to extract and separate the debris that may be generated during drill bit operation. The mechanism generates negative pressure airflow through the fan blades, which blocks the debris through the separation chamber. At the same time, the mechanism uses a motor to drive the screw to move the push plate, thereby preventing the separation chamber from being blocked. The debris is stored in the lower area of ​​the separation chamber, achieving the effects of protection, debris separation and long-term use.

[0015] The support and positioning mechanism provides planar positioning and scale coordinates for users when drilling, enabling them to keep the drill bit perpendicular to the drilling surface to ensure drilling results.

[0027] Furthermore, multiple scale support plates 407 are provided, and the scale support plates 407 are arranged in an array on the outside of the sleeve 405, with the scale support plates 407 array spaced at 90 degrees.

[0028] Furthermore, a scale groove is provided on one side of the scale support plate 407.

[0029] Furthermore, the scale support plate 407 is configured as a rigid structure. Example 2

[0030] This mechanism is used to remove and separate the debris generated during the output of drill bit 3. It solves the problem that traditional devices cannot handle the potential injury caused by debris. (See also...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the protective mechanism 5 includes a base 501, which is fixedly connected to the upper surface of the drill body 2. An exhaust vent 502 communicating with the outside is opened inside one side of the base 501. An air chamber 503 is opened inside the base 501, communicating with the exhaust vent 502. A motor 504 is fixedly connected inside the base 501, and a fan blade 505 is fixedly connected to the output end of the motor 504. The fan blade 505 is located inside the air chamber 503 and above the exhaust vent 502. A separation chamber 506 is opened inside the base 501, and the exhaust vent 502 is located to the left of the air chamber 503. The air chamber 503 is located above the exhaust vent 502. A filter structure is fixedly connected between the separation chamber 506 and the air chamber 503. A suction pipe 507 is connected inside the separation chamber 506 and is fixedly connected inside the limiting sleeve 408. The suction pipe 507 is connected to the inside of the sleeve 405. A housing 508 is fixedly connected to the upper surface of the base 501. A motor 509 is fixedly connected inside the housing 508. A screw 510 is fixedly connected to the output end of the motor 509. The screw 510 is rotatably connected inside the separation chamber 506. A push plate 511 is threadedly connected to the output end of the screw 510. The push plate 511 is clearance-fitted with the surface of the filter structure. A door 512 is slidably connected inside one side of the separation chamber 506.

[0031] Furthermore, the separation chamber 506 extends to the lower side of the filter structure.

[0032] Furthermore, the pusher plate 511 and the hard filter plate are both provided with the same arc surface on the side that is close to each other, and the filter structure is set as a hard filter plate.

[0033] In actual operation, when using this device, the user holds the electric drill and then places the scale support plate 407 against the surface to be drilled. The user can adjust the position of the drill bit 3 relative to the drilling point using multiple scale support plates 407. The user then starts the electric drill, causing the drill bit 3 to output power, and simultaneously pushes the drill closer to the drilling surface. At this point, the scale support plate 407 is in contact with the drilling surface, ensuring the drill bit 3 remains perpendicular to the drilling surface. During this process, because the scale support plate 407 forms a support relationship with the spring 404 through the sleeve 405 and support rod 403, the distance between the scale support plate 407 and the drill bit 3 changes as the drill bit 3 drills in. During drilling, the user starts the motor 504 and motor 509. When the motor 504 outputs power, it will spray air inside the air chamber 503. A negative pressure is generated on the side, which extends into the sleeve 405 through the suction pipe 507. The sleeve 405 is in contact with the drill surface, allowing the drilled debris to form an airflow through the gap between the sleeve 405 and the drill surface. The airflow carries the debris into the separation chamber 506. The filter plate inside the separation chamber 506 will block the debris. The motor 509 synchronously drives the screw 510 to make the push plate 511 remove the debris that may accumulate on the surface of the filter plate, so that the debris accumulates in the windless area on the lower side of the separation chamber 506. Since only one side of the push plate 511 is in contact with the inner wall of the separation chamber 506, the debris can be sent to the corner of the separation chamber 506 to accumulate when the push plate 511 returns, so that the filter plate can be effective for a long time. The filtered air is separated through the exhaust port 502. The user can unplug the door 512 to empty the debris when needed.
