Description

[Technical Field]

[0001] This utility model relates to the field of power tools, and in particular to an adjustment component and a power tool. [Background Technology]

[0002] Power tools are a type of instrument that uses a motor and transmission mechanism to drive a working head, enabling handheld and mobile use. Existing power tools have multiple working modes. Users can adjust the working mode by operating the adjustment components to adjust the speed or gear of the power tool. Existing adjustment components usually include an adjustment panel with buttons. Users can adjust the working mode of the power tool by operating the adjustment buttons.

[0003] As disclosed in Chinese Patent Publication No. CN2155617Y, a key structure includes a plastic key body and a silicone rubber integrally molded. The silicone rubber has a bevel and a guide post. The bevel occupies a large space, and the mold for this one-piece injection molding structure of hard and soft rubber is expensive and costly.

[0004] Existing buttons also include plastic buttons, which are harder and have a poor tactile feel when pressed.

[0005] Therefore, it is indeed necessary to design an adjustment component and power tool to overcome the shortcomings of the existing technology. [Utility Model Content]

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustment component and power tool that offer a good pressing feel and low cost. The specific technical solution is as follows:

[0011] A further improvement is that the distance by which the support extends toward the adjustment contact is less than the length of the limiting hole.

[0012] A further improvement is that the support portion and the through hole are interference-fitted.

[0013] A further improvement is as follows: the adjustment panel is provided with a through hole adjacent to the limiting hole and through which the pressing part passes. The diameter of the through hole is smaller than the diameter of the limiting hole and forms a stepped part. One end of the support part abuts against the stepped part.

[0014] A further improvement is provided: the control panel is provided with at least one protrusion facing the through hole and at least partially accommodating the pressing part, the cylindrical part abutting against the other end of the support part.

[0015] A further improvement is as follows: at least one abutting part protruding along its inner wall is provided at the end of the limiting hole away from the pressing surface, and the abutting part abuts against the other end of the support part.

[0016] A further improvement is as follows: a groove is provided on the inner wall of the end of the through hole away from the pressing surface, and a metal ring is engaged in the groove, with one end of the metal ring abutting against the other end of the support.

[0017] Another aspect of this utility model is: an electric tool, the electric tool including a housing, a control board and the adjustment components as described above, the control board being located inside the housing and having the adjustment contacts, and the panel being mounted on the housing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention provides an adjustment component that replaces the plastic buttons or one-piece molded soft and hard rubber adjustment components in the prior art with an adjustment panel and a rubber button. On the one hand, the rubber button has a better pressing feel and user experience. On the other hand, the button is installed in the limiting hole of the adjustment panel, which reduces the mold cost. In addition, by setting a cylindrical part on the control panel, or setting an abutting part or metal ring inside the limiting hole to abut the support part, the rubber button will not disengage from the limiting hole under the pressure when the user presses it, thereby improving its service life.

[0040] The terminology used in this utility model is for the purpose of describing specific embodiments only and is not intended to limit the utility model. For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the technical features referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the utility model.

[0041] Please see Figures 1-5 This utility model describes the power tool in detail.

[0042] In this embodiment, such as Figure 1 The power tool 100 includes an adjustment component 1, a housing 2, a motor, a transmission mechanism (not shown in the figure), and an output shaft 3. The motor, transmission mechanism, and output shaft 3 are located inside the housing 2, and the motor drives the output shaft 3 to work through the transmission mechanism.

[0043] like Figure 2 As shown, the adjustment assembly 1 includes an adjustment panel 11, a button 12, and a control plate 13. The adjustment panel 11 is mounted on the housing 2 and located outside the control plate 13. The control plate 13 is provided with adjustment contacts 131 to adjust the speed, working mode, or other commands of the power tool 100. The button 12 is provided with a support portion 121, a pressing portion 122, and a flexible connecting portion 123 connecting the support portion 121 and the pressing portion 122. The support portion 121 surrounds the pressing portion 122 and supports the pressing portion 122 through the flexible connecting portion 123. The support portion 121, the pressing portion 122, and the flexible connecting portion 123 are made of rubber material. The adjustment panel 11 is integrally injection molded. It has a limiting hole 111 extending along the support portion 121 and used to support the support portion. The adjustment panel 11 has a through hole 1110 adjacent to the limiting hole 111 and through which the pressing portion 122 passes. The diameter of the through hole 1110 is smaller than the diameter of the limiting hole 111 and forms a stepped portion 1111. The support portion 121 is interference-fitted with the limiting hole 111 of the adjustment panel 11, and one end of the support portion 121 abuts against the stepped portion 1111. The limiting button 12 falls outward from the through hole 1110. The pressing portion 122 extends toward the control plate 13 and is opposite to the adjustment contact 131 on the control plate 13. When adjustment is required, the user presses the pressing part 122 of button 12. Under the pressure, the flexible connecting part 123 deforms, and the pressing part 122 moves axially downward relative to the supporting part 121 and touches the adjustment contact 131 on the control plate 13. The contact between the button 12 and the adjustment contact 131 on the control plate 13 triggers the control plate 13 to issue an adjustment control command, thereby triggering the adjustment. When the pressing pressure is removed, the flexible connecting part 123 returns to its original deformation, the adjustment operation is completed, and it is ready for the next adjustment operation.

[0044] By adopting the above technical solution, and by setting the adjustment panel 11 and the flexible button 12 to replace the plastic button or the one-piece molded soft and hard plastic adjustment components in the prior art, on the one hand, the flexible button 12 has a good pressing feel and a good user experience; on the other hand, the button 12 is installed in the limiting hole 111 of the adjustment panel 11, and the mold cost is low.

[0045] In one implementation, such as Figures 2 to 3 As shown, the support portion 121 of the button 12 is arranged around the circumference of the pressing portion 122. The support portion 121 extends toward the adjustment contact 131, and its extension distance is less than the length of the limiting hole 111. The support portion 121 is provided with at least one groove 1211 opposite to the limiting hole 111. When the button 12 is inserted into the limiting hole 111, the support portion 121 is compressed and installed in the limiting hole 111, so that the support portion 121 deforms. Since the button 12 is made of flexible material and has a certain elasticity, the support portion 121 will generate a restoring elastic force due to deformation, so that the support portion 121 abuts more tightly against the limiting hole 111.

[0046] In one implementation, such as Figures 2 to 4 As shown, the support portion 121 of the button 12 is interference-fitted with the limiting hole 111 of the adjustment panel 11. The support portion 121 extends toward the adjustment contact 131, and its extension distance is less than the length of the limiting hole 111. The control plate 13 has at least one protrusion toward the through hole 1110 of the adjustment panel 11, and at least partially accommodates the cylindrical portion 132 of the pressing portion 122. The cylindrical portion 132 abuts against the end of the support portion 121 facing the control plate 13. When the user presses the button 12, the flexible connection portion 123 deforms under the pressing force. At the same time, the support portion 121 is also subjected to downward pressing force, causing it to have a downward movement tendency along the inner wall of the limiting hole 111. One end of the cylindrical portion 132 abuts against the end of the support portion 121 facing the control plate 13 to prevent the button 12 from disengaging downward from the limiting hole 111 under the pressing force, thereby affecting the use of the adjustment assembly 1. In this design, the protruding structure 132 on the control panel 13 abuts against the support, ensuring that the button 12 is more reliably installed in the through hole 111, thereby improving the service life of the adjustment component 1.

[0047] In one implementation, such as Figures 5 to 6As shown, the support portion 121 of the button 12 is interference-fitted with the limiting hole 111 of the adjustment panel 11. The support portion 121 extends toward the adjustment contact 131, and its extension distance is less than the length of the limiting hole 111. At least one abutting portion 1112 protruding along the inner wall of the limiting hole 111 is provided at one end of the limiting hole 111 away from the pressing surface. The abutting portion 1112 abuts against the other end of the support portion 121. The abutting portion 1112 is made of plastic material and is integrally injection molded with the adjustment panel 11. When the button 12 is installed from below the limiting hole 111, the button 12 will be blocked by the abutting portion 1112. Since the button 12 is made of flexible material, the button 12 can undergo slight deformation to receive into the area of ​​the limiting hole 111 above the abutting portion 1112. The abutting portion 1112 abuts against the end of the support portion 121 toward the control plate 13. When the user presses button 12, the flexible connecting part 123 deforms under the pressure, and at the same time, the supporting part 121 is also subjected to downward pressure, causing it to tend to move downward along the inner wall of the limiting hole 111. One end of the abutting part 1112 abuts against the end of the supporting part 121 facing the control plate 13, thereby preventing button 12 from disengaging downward from the limiting hole 111 under the pressure. In this design, the abutting part 1112 and the adjustment panel 11 are integrally injection molded, resulting in low mold cost and more reliable button 12 installation, which helps to improve the service life of the adjustment assembly 1.

[0048] In one implementation, such as Figures 7 to 8 As shown, the support portion 121 of button 12 is interference-fitted with the limiting hole 111 of adjustment panel 11. The support portion 121 extends towards the adjustment contact 131, and its extension distance is less than the length of the limiting hole 111. A groove 1113 is provided at the end of the limiting hole 111 away from the pressing surface. A metal ring 1114 is engaged in the groove 1113. One end of the metal ring 1114 abuts against the other end of the support portion 121. When the user presses button 12, the flexible connection portion 123 deforms under the pressing force. At the same time, the support portion 121 is also subjected to downward pressing force, causing it to tend to move downward along the inner wall of the limiting hole 111. One end of the metal ring 1114 abuts against the end of the support portion 121 facing the control plate 13, thereby preventing button 12 from disengaging downward from the limiting hole 111 under the pressing force. In this design, the metal ring 1114 is easy to install, and the button 12 is more reliably installed, which is beneficial to improving the service life of adjustment assembly 1.
