Description

Technical Field

[0001] The utility model relates to the technical field of hammer drills, in particular to a dust cap structure on an electric drill. Background Art

[0002] Electric drills are commonly used tools and are also the most in-demand electric tool products. They can be divided into three categories: hand drills, impact drills, and hammer drills. They are widely used in various industries to make the drill bit scrape the surface of objects and better penetrate objects. With existing electric drills, a lot of dust will be generated when people drill holes in the wall. Therefore, a dust cap is provided between the head and the drill rod to prevent dust from entering the inside of the electric drill. However, the existing dust cap design structure has defects and the dustproof effect is not good enough, so it needs further improvement. Summary of the invention

[0003] The purpose of the utility model is to solve the problems raised in the above background technology and to provide a dust cap structure for an electric drill.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a dust cap structure on an electric drill, comprising a cap body, on which a mounting portion, a dustproof main body portion and a dustproof blocking portion are respectively provided, the central axes of the mounting portion, the dustproof main body portion and the dustproof blocking portion are on the same straight line, and the mounting portion and the dustproof blocking portion are respectively located on both sides of the dustproof main body portion; a plurality of blocking bosses are evenly arranged on the circumferential side surface of the dustproof blocking portion, and a dust removal groove is formed between each pair of blocking bosses.

[0005] In the above-mentioned dust cap structure on an electric drill, the blocking boss extends from the end of the dust blocking portion to the end surface where the dust main body portion and the dust blocking portion meet.

[0006] In the above-mentioned dust cap structure on an electric drill, the dustproof main body is designed to be gradually inclined outward from the end portion intersecting with the dustproof blocking portion to the end portion intersecting with the mounting portion.

[0007] In the dust cap structure on the above-mentioned electric drill, a front dust shield part, a middle dust shield part and a rear dust shield part are gradually formed between the blocking boss and the dust shield main body, and the dust shield parts are connected in an arc transition design.

[0008] The beneficial effects of the utility model are:

[0009] The utility model adopts a split dust cap design, which can rotate synchronously with the drill rod. The blocking boss designed at the end and the dust removal groove formed can generate airflow with the rotation, thereby having a blocking force on the generated dust and dispersing it toward the circumference, thereby effectively preventing the dust from entering the inside of the electric drill from the drill rod, and effectively extending the service life of the electric drill. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a cross-sectional view of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described in conjunction with the accompanying drawings.

[0013] See also Figure 1 , Figure 2 The utility model provides a dust cap structure for an electric drill, which is characterized by comprising a cap body 1, on which a mounting portion 2, a dustproof main body portion 3, and a dustproof blocking portion 4 are respectively arranged, the central axes of the mounting portion 2, the dustproof main body portion 3, and the dustproof blocking portion 4 are on the same straight line, and the mounting portion 2 and the dustproof blocking portion 4 are respectively located on both sides of the dustproof main body portion 3; a plurality of blocking bosses 5 are evenly arranged on the circumferential side surface of the dustproof blocking portion 4, and dust removal grooves 6 are formed between the blocking bosses 5.

[0014] The cap body 1 is installed and connected through the cooperation of the mounting part 2. The cap body 1 rotates with the drill rod. The blocking boss designed at the end and the dust removal groove formed will generate airflow with the rotation, thereby having a blocking force on the generated dust and dispersing it to the circumference, thereby effectively preventing dust from entering the electric drill from the drill rod, and effectively extending the service life of the electric drill.

[0015] Furthermore, the blocking boss 5 extends from the end of the dustproof blocking portion 4 to the end face where the dustproof main body 3 and the dustproof blocking portion 4 meet, and preferably, a front dust blocking portion 7, a middle dust blocking portion 8, and a rear dust blocking portion 9 are gradually formed between the blocking boss 5 and the dustproof main body 3, and each dust blocking portion is designed to be connected in an arc transition.

[0016] The dustproof main body portion 3 is designed to be gradually inclined outward from the end portion intersecting with the dustproof blocking portion 4 to the end portion intersecting with the mounting portion 2 .

[0017] The connection and coordination design between the blocking boss 5 and other parts can better block and disperse the dust.

[0018] The dust cap structure on an electric drill provided by an embodiment of the utility model is introduced in detail above. The principle and implementation mode of the utility model are explained in this article by using specific examples. The description of the above embodiments is only used to help understand the technical solution disclosed by the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation of the utility model.
