Description

Technical Field

[0001] This utility model relates to the field of grinders, and in particular to a grinder charging base. Background Technology

[0002] Most grinders on the market currently use contact charging, which involves setting a charging port at the bottom of the grinder and a base with a power supply port. When the bottom of the grinder is placed on the base, the two charging ports come into contact, and the grinder can be charged.

[0003] Since the working environment of the grinder is often dusty, dust easily adheres to the interface of the base, thus affecting the contact effect.

[0004] Therefore, there is an urgent need for a grinder charging base that can hide the charging port on the grinder base when not charging, thereby reducing or avoiding dust adhesion that affects the charging contact effect. Utility Model Content

[0020] 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.

[0021] The purpose of this invention is to provide a grinder charging base to solve the problems existing in the prior art.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] This embodiment provides a grinder charging base, such as Figure 1 and 2 As shown, the device includes a base body 1, with a charging slot 2 vertically downward on the upper surface of the base body 1. The charging slot 2 is used to insert the grinder body 3. The inner wall of the charging slot 2 is provided with a first charging interface 4, and the outer wall of the grinder body 3 is provided with a second charging interface (not shown in the figure). In this embodiment, the first charging interface 4 and the second charging interface cooperate. The above structure and arrangement are similar to the existing conventional grinder charging structure. The difference is that a pressure plate 5 is floatingly provided at the bottom of the charging slot 2. A transmission component is provided at the bottom of the pressure plate 5. The transmission component is connected to the first charging interface 4. When the pressure plate 5 is pressed down, the transmission component drives the first charging interface 4 to be pushed out from the inner wall of the charging slot 2.

[0025] In one embodiment, the upper surface of the pressure plate 5 is provided with a retainer 6, which cooperates with the bottom of the grinder body 3. By setting the retainer 6, the grinder body 3 and the base body 1 can be aligned and inserted. The specific shape of the retainer 6 is not limited in this embodiment, as long as it can achieve the above function.

[0026] As one implementation method, the inner wall of the charging slot 2 is provided with a hidden opening 7, and the first charging interface 4 is retractably disposed in the hidden opening 7, thereby achieving a hidden effect.

[0027] In one implementation, a first spring 8 is provided between the bottom of the base body 1 and the pressure plate 5. When the grinder body 3 is removed, the first spring 8 will spring up the pressure plate 5, thereby achieving the floating effect of the pressure plate 5.

[0028] As one implementation method, the bottom of the base body 1 is provided with a limiting support structure 9, which mainly plays the role of limiting and supporting. When the grinder body 3 is lowered, it can limit the distance of the pressure plate 5 sinking, so that the grinder body 3 will not be placed crooked, thereby enabling precise matching with the first charging interface 4.

[0029] In one implementation, the transmission assembly includes an L-shaped lever 10. One end of the L-shaped lever 10 engages with the bottom of the pressure plate 5, and the other end connects to the first charging port 4. A second spring 11 is provided between the side of the L-shaped lever 10 and the base body 1. The second spring 11 assists the first charging port 4 in popping out and also makes the first charging port 4 a flexible connection, giving the popping out of the first charging port 4 a flexible buffering effect. This prevents the charging port from getting stuck when the grinder body 3 is placed into the charging slot 2, making it easier to match successfully. It should be understood that the L-shaped lever 10 is floatingly set inside the base body 1. The second spring 11 on its side acts as a lever fulcrum. When the pressure plate 5 presses down on one end of the L-shaped lever 10, the first charging port 4 at the other end can pop out for charging. The second spring 11 can act as a fulcrum, provide assistance, and buffer. There is no need to set a fixed hinge structure, making the setting of the L-shaped lever 10 simpler and more ingenious, reducing production difficulty and production cost.

[0030] As one implementation method, a limiting structure 12 is provided between the pressure plate 5 and the L-shaped lever 10, so that the fit between the L-shaped lever 10 and the pressure plate 5 is more stable and will not loosen.

[0031] In one implementation, a support structure 13 is provided between the L-shaped lever 5 and the second spring 11 to support the second spring 11 and limit the retraction distance of the first charging interface 4, thus ensuring the stability of the structure while forming the lever structure.

[0032] The present invention provides a grinding tool charging base, which uses a transmission component as a connection structure between the pressure plate and the first charging interface. The first charging interface can only be pushed out when the grinding tool is placed in the charging slot and the pressure plate is pressed down. When not charging, the first charging port can be hidden in the body of the base, thereby effectively reducing or avoiding contact between the first charging interface and dust, and forming an effective protection for it.

[0033] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
