Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a drilling rig output shaft device with impact teeth. Background Technology

[0002] A drilling rig is a handheld power tool that combines the functions of an impact drill and a hammer drill. The impact drill primarily uses rotary cutting, while an impact mechanism drives the drill bit, creating a reciprocating hammering motion perpendicular to the drill bit's rotation plane. It is used for drilling holes in materials such as concrete, brick, ceramic tiles, and marble. The hammer drill uses impact force to drive a steel chisel, used for grooving, creating large holes, or breaking concrete in materials such as concrete and brick.

[0003] The output shaft of existing drilling rigs is equipped with impact teeth, but in actual use, it is not convenient and quick to change the operating status of the drilling rig according to the actual work needs. Therefore, corresponding improvements are needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drill output shaft device with impact teeth to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drill output shaft device with impact teeth, comprising a drill body, an impact handle rotatably connected to the output end of the drill body, and an output shaft movably mounted on one side of the impact handle, a dust collection shell installed at one end of the drill body, and impact teeth and threaded impact teeth installed inside the dust collection shell, and an output shaft half-shaft connected to the inside of the drill body via a motor drive, and one end of the output shaft half-shaft being mounted to one end of the output shaft via a connecting rod.

[0006] Preferably, a vacuum port is installed on the bottom of the outer surface of the vacuum casing, and mounting clips are installed on both sides of the bottom of the vacuum port.

[0007] Preferably, the impact tooth body and the threaded impact tooth are meshed and connected to each other, and both the impact tooth body and the threaded impact tooth are sleeved and installed on the outer surface of the connecting rod.

[0008] Preferably, the bottom end of the vacuum suction interface is movably installed with the connector of the vacuum cleaner via two sets of clips.

[0009] Preferably, the outer surface of the output shaft is provided with a threaded groove near the end, and the output shaft can be screwed to one end of the drill bit through the threaded groove.

[0010] Preferably, a rotary button is installed on one side of the drilling rig body, and the rotary button has multiple adjustable positions.

[0011] Preferably, a hand-held rod is installed at the other end of the drilling rig body, and the hand-held rod is a grippable irregular-shaped rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as the output shaft, impact handle, dust extraction interface, impact teeth, threaded impact teeth, and output shaft half-shaft, the problem of existing drilling rigs having impact teeth installed at the end of the output shaft, which makes it difficult to conveniently and quickly change the operating status of the drilling rig according to actual work needs during actual use, can be effectively solved.

[0014] The user can hold the drill body in their hand using the handle, allowing for operation. The output shaft is screwed to one end of the drill bit via a threaded groove. The impact handle has a rotating function, allowing the user to adjust the drill mode (hammering mode or non-hammering mode). During drill body operation, the output shaft half-shaft rotates under the motor's operation, causing the connecting rod and output shaft to rotate accordingly. Simultaneously, the hammering function is achieved through the combined impact of the impact teeth and threaded impact teeth. The output shaft and output shaft half-shaft can be split into two, lengthening the output shaft and enabling telescopic hammering. The dust collection connector can be movably installed with a vacuum cleaner connector. A rotary button with multiple adjustable settings is installed on one side of the drill body, allowing control of the output shaft and drill bit speeds. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] according to Figures 1-3 As shown, the system includes a drill body 8. An impact handle 2 is rotatably connected to the output end of the drill body 8. An output shaft 1 is movably mounted on one side of the impact handle 2. A threaded groove is provided on the outer surface of the output shaft 1 near its end, and the output shaft 1 can be screwed onto one end of a drill bit via the threaded groove. A dust collection housing 3 is installed at one end of the drill body 8. Impact teeth 4 and threaded impact teeth 5 are installed inside the dust collection housing 3. The impact teeth 4 and threaded impact teeth 5 are meshed together and connected to each other. Both impact teeth 4 and threaded impact teeth 5 are sleeved on the outer surface of a connecting rod. The drill body 8... The internal structure is connected to an output shaft half-shaft 6 via a motor drive. One end of the output shaft half-shaft 6 is connected to one end of the output shaft 1 via a connecting rod. A dust suction port 7 is installed on the bottom surface of the dust suction housing 3. Mounting clips are installed on both sides of the bottom of the dust suction port 7. The bottom of the dust suction port 7 is movably mounted to the vacuum cleaner's connector via two sets of clips. A rotary button with multiple adjustable positions is installed on one side of the drill body 8. A handheld handle is installed on the other end of the drill body 8. The handheld handle is a uniquely shaped handle; its specific shape can be found in [reference needed]. Figure 1 As shown.

[0021] The user can hold the drill body 8 in their hand using the handle, allowing them to operate the drill body 8. The output shaft 1 can be screwed to one end of the drill bit via a threaded groove. The impact handle 2 has a rotating function, allowing the user to adjust the drilling mode of the drill body 8, i.e., the hammering mode or the non-hammering mode. During the operation of the drill body 8, the output shaft half-shaft 6 will rotate under the action of the motor, allowing the connecting rod and the output shaft 1 to rotate accordingly. Simultaneously, the hammering function is achieved through the interaction of the impact teeth 4 and the threaded impact teeth 5. The hammering is achieved by the interaction of the impact teeth 4 and the impact threaded teeth 5 to generate force. The output shaft 1 and the output shaft half-shaft 6 can split the original single output shaft into two, lengthening the output shaft 1 and enabling the extension and retraction hammering function of the output shaft 1. The dust suction interface 7 can be movably installed with the connector of a vacuum cleaner. A rotary button is installed on one side of the drill body 8, and the rotary button has multiple adjustable positions, thereby controlling the speed of the output shaft 1 and the drill bit.
