According to the connecting rod for the small household appliances, the buffering function is achieved through the connecting rod with the deformable thin wall, and the service life is prolonged.

Description

Technical Field

[0001] The utility model relates to the field of small household appliances, in particular to a connecting rod used for small household appliances. Background Art

[0002] Small household appliances include razors and hair trimmers. Some of them use connecting rods to transmit power. Conventional connecting rods are made of plastic, and the overall structure is relatively rigid. They do not have the ability to expand and contract, and are unable to buffer when they are subjected to large impacts when transmitting power. On the one hand, this can easily affect the service life, and on the other hand, it can easily generate noise. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a leakage protection switch with a terminal isolation protection structure, which mainly solves the problem that the connecting rod of conventional small household appliances adopts a rigid structure and cannot be buffered by impact.

[0004] The technical solution of the utility model is:

[0005] A connecting rod for small household appliances, comprising a rod body, the rod body comprising

[0006] Two connecting ends are connected via an elastic thin wall, and the connecting ends are provided with connecting parts for connecting with the transmission member.

[0007] The connecting portion is a rotating shaft.

[0008] The connecting portion is an axial hole.

[0009] A sink groove is arranged on the outer wall of the connecting end.

[0010] The rod body is provided with a through slot which penetrates through the rod body, and the thin walls are provided on both sides of the through slot.

[0011] The thin wall includes a middle section and a transition section for connecting with the connecting end, and the cross-sectional area of ​​the transition section gradually decreases during the process of extending from one end of the transition section for connecting with the connecting end to one end of the transition section for connecting with the middle section.

[0012] The rod body is made of wear-resistant material.

[0013] The beneficial effects of the utility model are as follows: the utility model provides a connecting rod for small household appliances, which realizes a buffering function and increases the service life by means of the connecting rod with a deformable thin wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a three-dimensional schematic diagram of an embodiment of the utility model.

[0016] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a connecting rod for small household appliances includes a rod body 1, the rod body includes two connecting ends 11, the two connecting ends are connected by an elastic thin wall 2, and the connecting end is provided with a connecting portion 3 for connecting to a transmission member. It has a thin wall connecting the two connecting ends, the thin wall can be deformed by force and has a certain elasticity to restore the original shape, and can shrink and buffer to reduce the impact force when it is hit, which can prevent hard collisions and can also reduce noise to a certain extent. As one of the available scenarios of this application, the utility model can at least be applied to the Chinese patent CN201720567996.3, and used instead of its transmission rod. Preferably, the rod body is formed by integral injection molding.

[0017] In this embodiment, as shown in the figure, the connecting portion is a rotating shaft.

[0018] In this embodiment, as shown in the figure, the connecting portion is an axial hole, which can be a round hole or a long hole.

[0019] In this embodiment, as shown in the figure, a sink 111 is provided on the outer wall of the connecting end, which can save usage and reduce weight.

[0020] In this embodiment, as shown in the figure, the rod body is provided with a through slot 13, and the thin walls are provided on both sides of the through slot. The through slot can be used to provide space for the thin wall to deform inwards when it is deformed, which is more convenient for use.

[0021] In this embodiment, as shown in the figure, the thin wall includes a middle section 21 and a transition section 22 for connecting to the connection end, and the cross-sectional area of ​​the transition section gradually decreases during the process from one end of the transition section for connecting to the connection end to one end of the transition section for connecting to the middle section. This is beneficial for product injection molding, and the middle section can be filled without excessive pressure during injection.

[0022] In this embodiment, as shown in the figure, the rod body is made of wear-resistant material, specifically POM, which has high heat resistance, bending strength, fatigue resistance, wear resistance and electrical properties.

[0023] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
