Description

Technical Field

[0001] This utility model relates to the field of electric hammer technology, specifically to an electric hammer dustproof mechanism and the electric hammer itself. Background Technology

[0002] A hammer drill is a power tool that combines rotation and impact functions. It is mainly used for drilling and breaking operations on hard materials such as concrete and brick. However, in actual use, especially in high-dust working environments, the dust prevention of hammer drills has always been a problem that needs to be solved.

[0003] However, electric hammers generate a lot of dust during use, which can easily enter the hammer or adhere to key parts such as the motor and transmission components. Long-term accumulation can reduce the working efficiency of the electric hammer and even cause component failure, affecting the normal operation and service life of the electric hammer. At the same time, electric hammers generate debris and other flying materials during operation, and existing protective measures are difficult to effectively block these flying materials, which may cause injury to the operator and may also have a certain impact on the electric hammer itself or its surrounding environment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a dustproof mechanism for electric hammers and the electric hammer thereof, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A dustproof mechanism for an electric hammer includes a dustproof cylinder. The inner wall of the dustproof cylinder is provided with a shielding component. The shielding component includes multiple sliding grooves opened on the inner wall of the dustproof cylinder. A shielding plate is provided on the inner wall of the sliding groove. A shielding telescopic cover is provided on one side of the shielding plate. One side of the shielding telescopic cover is connected to the inner wall of the sliding groove. A fixing screw is connected to one side of the shielding plate through a bearing. One end of the fixing screw is threadedly connected to the dustproof cylinder.

[0008] Furthermore, in order to better protect the electric hammer from dust and assist in blocking flying debris, an auxiliary component is provided at one end of the dustproof cylinder. The auxiliary component includes an auxiliary groove at one end of the dustproof cylinder, with a protective cover connected to the inside of the auxiliary groove by threads. The other end of the dustproof cylinder is connected to a second telescopic shield, and one end of the second telescopic shield is provided with a mounting base via a second bearing.

[0009] Furthermore, one end of the mounting base is snapped into a fixing seat.

[0010] Furthermore, the surface of the fixing screw has multiple limiting plates, and a limiting spring is provided on one side of the limiting plate. One end of the limiting spring is connected to the surface of the dustproof cylinder.

[0011] Furthermore, to better improve the dustproof sealing performance of the shield, a sealing gasket is provided on one side of the shield, and the sealing gasket is adapted to one side of the shield.

[0012] According to another aspect of this application, an electric hammer is provided, comprising an electric hammer, the output end surface of the electric hammer contacting one side of a sealing gasket, the surface of the electric hammer being connected to a fixed base, and a dustproof sleeve being fitted onto the output end of the electric hammer.

[0013] The beneficial effects of this utility model are as follows: By using the shielding component installed in the dustproof cylinder, not only can the gap between the dustproof cylinder and the electric hammer be tightly sealed to prevent dust from entering the electric hammer from these gaps, but the sealing performance between the dustproof cylinder and the electric hammer is further improved. This effectively protects the key parts of the electric hammer, such as the motor and transmission components, preventing dust from adhering to these parts and affecting their normal operation. It also maintains good ventilation and heat dissipation performance, and the heat dissipation effect will not be affected by the accumulation of dust, thereby ensuring the working efficiency and service life of the motor. At the same time, the auxiliary component installed in the dustproof cylinder can shield the debris that splashes during the use of the electric hammer, preventing the debris from splashing directly onto the operator, thereby effectively protecting the operator's safety and avoiding accidental injuries such as scratches and bumps caused by flying debris. It also reduces the pollution of the surrounding environment by flying debris and the potential hazards to surrounding equipment and personnel. Attached Figure Description

[0022] 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.

[0023] Example 1:

[0024] like Figures 1-3 As shown, a dustproof mechanism for an electric hammer according to an embodiment of the present invention includes a dustproof cylinder 1 for installation on the surface of the electric hammer. A shielding component 2 is provided on the inner wall of the dustproof cylinder 1. The shielding component 2 includes two sliding grooves on the inner wall of the dustproof cylinder 1, and a shielding plate 201 is provided on the inner wall of each sliding groove to shield the gap between the dustproof cylinder 1 and the electric hammer. A sealing gasket 5 is provided on one side of the shielding plate 201 to improve sealing. The sealing gasket 5 is adapted to one side of the shielding plate 201. A shielding telescopic cover 205 is provided on one side of the shielding plate 201 to assist in sealing. To help block dust, one side of the telescopic shield 205 is connected to the inner wall of the sliding groove. One side of the shield 201 is connected to a fixing screw 202 via a bearing for adjusting the limiting plate 203. One end of the fixing screw 202 is threadedly connected to the dustproof cylinder 1. The surface of the fixing screw 202 contacts two limiting plates 203 to prevent the fixing screw 202 from retracting. A limiting spring 204 is provided on one side of the limiting plate 203 to limit the limiting plate 203. One end of the limiting spring 204 is connected to the surface of the dustproof cylinder 1.

[0025] Example 2:

[0026] like Figures 2-5As shown, an auxiliary component 3 is provided at one end of the dustproof cylinder 1. The auxiliary component 3 includes an auxiliary groove at one end of the dustproof cylinder 1, with a protective cover 301 threaded inside the auxiliary groove to shield the debris splashed during the use of the electric hammer. The other end of the dustproof cylinder 1 is connected to a shielding telescopic cover 302 to provide auxiliary shielding for the moving parts of the electric hammer. One end of the shielding telescopic cover 302 is provided with a mounting base 303 via a bearing 2 for mounting one end of the shielding telescopic cover 302. One end of the mounting base 303 is snapped with a fixing base 4 for mounting the mounting base 303. The mounting base 303 has a movable groove (not shown in the figure) in actual use. An auxiliary handle (not shown in the figure) is provided on the inner wall of the movable groove. A limiting screw (not shown in the figure) is threaded on the auxiliary handle for limiting and fixing the auxiliary handle. One end of the limiting screw is threadedly connected to the mounting base 303.

[0027] Example 3:

[0028] like Figures 1-2 As shown, according to another aspect of this application, an electric hammer is provided, including an electric hammer 6. A filter shield (not shown in the figure) is provided at the heat dissipation part of the electric hammer 6. The filter shield has a snap-fit ​​and detachable structure, which facilitates subsequent cleaning and maintenance. The output end surface of the electric hammer 6 contacts one side of the sealing gasket 5. The surface of the electric hammer 6 is connected to the fixed base 4. The dustproof cylinder 1 is sleeved on the output end of the electric hammer 6.

[0029] The electric hammer 6 has an electrical connection wire (not shown in the figure), and since the electric hammer 6 is existing technology, it will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, during use, the baffle plate 201 moves flexibly on the inner wall of the dustproof cylinder 1 through the sliding groove, covering the gap between the output end of the electric hammer 6 and the dustproof cylinder 1. Then, the fixing screw 202 is threadedly connected to the dustproof cylinder 1. Rotating the fixing screw 202 can push the baffle plate 201 to fit tightly against the surface of the electric hammer. The limiting plate 203 and the limiting spring piece 204 together prevent the fixing screw 202 from loosening and falling back, ensuring the stability of the baffle plate 201.

[0032] The sealing gasket 5 on one side of the shield 201 is in direct contact with the output end of the electric hammer 6 to form a flexible sealing layer, which further prevents dust from entering the interior of the electric hammer 6. The shield telescopic cover 205 is connected between the shield 201 and the inner wall of the sliding groove. It moves and expands with the shield 201 to fill the dynamic gap and prevent dust from seeping in from the side.

[0033] The protective cover 301 is threaded into the auxiliary groove at the front end of the dust cylinder 1, directly blocking the debris splashed during the operation of the electric hammer 6, preventing it from splashing onto the operator or the surrounding environment. The second telescopic shield 302 is connected to the dust cylinder 1 at one end and movably connected to the mounting base 303 through the bearing 2 at the other end. When the electric hammer 6 is in operation, the second telescopic shield 302 can expand and contract with the vibration of the electric hammer 6, always covering the moving parts of the electric hammer 6 and preventing debris from escaping from the rear. Then, the mounting base 303 is snapped onto the fixed base 4 (the fixed base 4 is connected to the surface of the electric hammer 6) to ensure that the auxiliary component 3 is stable as a whole. The gripping position of the auxiliary handle can be adjusted according to the actual situation through the auxiliary handle and the limiting screw in the movable groove set in the mounting base 303.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
