Description

Technical Field

[0001] The invention relates to a handheld electric tool, in particular to a convenient deicing tool, belonging to the technical field of electric tools. Background Art

[0002] In order to remove floating ice and snow on glass in a low-temperature environment, Chinese patent application document No. 201880092854.3 discloses a deicing tool and a handheld deicer for a deicer, which is mainly composed of a deicing disk (disc-shaped holder) driven by a motor through a transmission mechanism, which can be driven to rotate around a rotation axis during operation, and scrape floating ice and snow on the glass with the help of multiple blades (joints) arranged on the outer side (first side). When the deicing disk of the existing deicer needs to be cleaned, maintained, or replaced during use, it needs to be removed with the help of tools, which is inconvenient. Summary of the invention

[0003] The primary purpose of the present invention is to address the shortcomings of the above-mentioned prior art and to provide a convenient deicing tool that can easily loosen the deicing tray without tools, thereby bringing convenience to cleaning, maintenance and replacement of the deicing tray.

[0004] A further object of the present invention is to provide a convenient deicing tool that can be automatically removed as needed, thereby bringing more convenience to the disassembly of the deicing tray.

[0005] In order to achieve the above primary purpose, the basic technical scheme of the convenient deicing tool of the present invention is: comprising a motor with a transmission device arranged in a housing, the power output shaft of the transmission device is fixedly connected to a connecting disk, a deicing blade disk with a bayonet is sleeved outside the connecting disk, a button with a first and a second axial position is installed in the connecting disk, and a radial moving pair is formed with at least two buckle sliders that can be radially retracted and tend to extend radially;

[0006] The buckle slider has a latching tooth adapted to the bayonet, and a first inclined surface wedged corresponding to the button unlocking inclined surface; when the buckle slider is in a radially extended limit position, the latching tooth is locked in the bayonet, and the first inclined surface enables the button to be in a first axial position through the unlocking inclined surface; when the button is pressed and in a second axial position, the unlocking inclined surface enables the buckle slider to be in a radially retracted position through the first inclined surface, and the latching tooth escapes from the bayonet.

[0007] It can be seen that when installing the de-icing blade disc, as long as it is mounted on the connecting disc and in the mounting position, the self-trend of the buckle slider can automatically make the locking teeth engage in the bayonet of the de-icing blade disc, so that it can be reliably positioned. When removing the de-icing blade disc, as long as the button is pressed to the second axial position, so that it overcomes the self-trend of the buckle slider and retracts radially, the locking teeth can be disengaged from the bayonet of the de-icing blade disc, so that it can be easily removed from the connecting disc.

[0008] In order to achieve a further purpose, the de-icing blade disc has a retracting inclined surface, the button has a third axial position, and the buckle slider has a second inclined surface adapted to the retracting inclined surface; when the button is pressed and passes through the second axial position and is in the third axial position, the second inclined surface causes the de-icing blade disc to axially shift through the retracting inclined surface. Therefore, when the de-icing blade disc is disassembled, after the button is pressed to make its locking teeth disengage from the de-icing blade disc bayonet, the button is continued to be pressed, and its second inclined surface will act on the retracting inclined surface, so that the de-icing blade disc that has been unfastened is separated from its fitting position on the connecting disc, making it easy to remove.

[0022] Embodiment 1

[0023] The structure of the convenient deicing tool in this embodiment is as follows Figure 1 As shown, a motor 1-2 is housed in a shell 1 with a handle 1-1. The motor 1-2 is inserted into a center hole of a connecting plate 2 through a power output shaft 1-3 driven by a gear box, and is then fixedly connected through an axial tightening screw 1-4.

[0024] The outer circle of the connecting disk 2 has three circumferentially evenly distributed positioning grooves 2-1 and three circumferentially evenly distributed clamping holes 2-2. The connecting disk 2 is fitted with a central ring 7-1 of the de-icing blade disk 7, which extends upward from the lower surface of the de-icing blade disk 7 with the ice scraper 7-6. The circumference of the central ring 7-1 has three circumferentially evenly distributed positioning ribs 7-3, which are respectively matched with the three circumferentially evenly distributed positioning grooves 2-1 on the outer circle of the connecting disk 2 to play a circumferential positioning role. The circumference of the central ring 7-1 has three circumferentially evenly distributed upwardly extending retreat inclined surfaces 7-4. The circumference of the central ring 7-1 has three evenly distributed clamping ports 7-2, and three circumferentially evenly distributed reinforcing ribs 7-5 extend outward.

[0025] A button 5 having the first, second and third axial positions is installed in the connecting disk 2 through a fixing ring 6 fixed thereto by screws, and forms a radial moving pair with three snap-on sliders 4 that can be radially retracted and tend to extend radially. The button 5 has three pairs of circumferentially evenly distributed unfastening inclined surfaces 5-1, and three circumferentially evenly distributed external circular planes 5-2. The inner hole of the fixing ring 6 has three circumferentially evenly distributed chord sections 6-1, which are respectively adapted to the corresponding button external circular planes 5-2, and play a role in circumferential limiting and axial guiding. The outer circumferential surface of the connecting disk 2 has three positioning grooves 2-1 that correspond to the positioning ribs 7-3 of the de-icing blade disc 7, so that the de-icing blade disc 7 is circumferentially positioned after assembly.

[0026] More specifically, the connection disk 2 has three radially extending grooves 2-3 evenly distributed in the circumferential direction, and the two inner side surfaces of each groove 2-3 respectively form a radial moving pair with the two outer side surfaces of the boss 4-1 of the buckle slider 4 installed therein. The middle part of the boss 4-1 has a groove 4-5 for accommodating the radial spring 3. Under the action of the radial spring, the buckle slider 4 tends to extend radially relative to the connection disk 2. The outer end of the boss 4-1 extends outward to form a latching tooth 4-3 that matches the latching hole 2-2 and the bayonet 7-2; the two sides of the boss 4-1 respectively extend downward to form a first inclined surface 4-2 that is correspondingly wedged with the unlocking inclined surface 5-1 of the button 5; the outer end of the boss 4-1 extends downward to form a second inclined surface 4-4 that is adapted to the retreat inclined surface 7-4 of the de-icing blade 7.

[0027] During use, when the de-icing blade disc 7 is installed, the buckle slider 4 is in the radial extension limit position under the ejection action of the spring 3, and its latching tooth 4-3 is latched in the bayonet 7-2 of the de-icing blade disc 7, so that it is axially in place and can be driven to rotate by the power output shaft 1-3 through the mutually fixed connecting disc 2 and the fixing ring 6. At this time, under the action of the first inclined surface 4-2 of the buckle slider 4 on the unfastening inclined surface 5-1, the button 5 is in the outermost first axial position; when the de-icing blade disc 7 needs to be disassembled, the button 5 is pressed inwards to make it first in the second axial position. When the button 5 is pressed to the right position, the unfastening slope 5-1 enables the buckle slider 4 to overcome the force of the spring 3 and to be in the radially retracted position through the first slope 4-2, and the latch tooth 4-3 disengages from the latch hole 7-2, so that the de-icing blade disc 7 can be axially separated from the connecting disc 2; then the button 5 is continuously pressed to make it pass through the second axial position and reach the innermost third axial limit position, the second slope 4-4 of the buckle slider 4 will act on the retracting slope 7-4 of the de-icing blade disc 7, generating an outward axial force thereon, resulting in the de-icing blade disc 7 being automatically moved out axially and removed.

[0028] It can be seen that the convenient deicing tool of this embodiment can not only quickly install the deicing blade disc, but also can release the deicing blade disc due to the release unlocking by a simple and convenient pressing operation without using tools, especially the release unlocked deicing blade disc can be automatically released by further pressing operation at the same time, so as to realize the quick disassembly and assembly of the deicing blade disc, which is very convenient. In addition, its assembly and disassembly structure is reliably connected, which can effectively avoid the risk of the blade disc or other parts such as the threaded connector falling off during use, and prevent the problem of scratching the glass and clogging the drainage hole due to the falling of screws.

[0029] Embodiment 2

[0030] The convenient deicing tool structure of this embodiment can be found in Fig.11 and Fig.12 Its basic structure is similar to that of the embodiment, the only difference is that the buckle positioning structure of the de-icing blade disc is evenly distributed at two locations instead of three locations in the circumferential direction, and its function and effect are basically the same as those of the embodiment.

[0031] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
