Utility model content
Technical problem to be solved in the utility model is the defect overcoming prior art, and provide a kind of for the permanent joint mechanism between rain shaving blade and rocking arm, it makes to be connected firmly between rain shaving blade and rocking arm, easy for installation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of for the permanent joint mechanism between rain shaving blade and rocking arm, it comprises:
Upper coupling element, for being connected with rocking arm;
Lower coupling element, for being connected with rain shaving blade, and the side of lower coupling element and upper coupling element is connected to form rotation shaft-like by supporting construction, and lower coupling element is connected by snap-in structure with the opposite side of upper coupling element; Wherein, snap-in structure comprises the engagement section of the clamping that cooperatively interacts and coordinates stopper, and coordinate stopper to be connected on lower coupling element or upper coupling element by a flexure strip, when upper coupling element presses to lower coupling element around rotation shaft side, engagement section coordinates in stopper because the elastic reaction of flexure strip is connected to securely; When upper coupling element around rotation shaft side away from lower coupling element time, engagement section detaches cooperation stopper due to the elastic reaction of flexure strip.
Further provide the version of the concrete setting position of a kind of engagement section and cooperation stopper, described engagement section is arranged on coupling element, described cooperation stopper is arranged on lower coupling element, and coordinates the junction of stopper and lower coupling element to be provided with flexure strip.
Further provide a kind of version of supporting construction; Described supporting construction comprises plug, slot and catch, and catch is arranged on the top of slot, and described plug insertion slot is interior thus formation rotates shaft-like.
Further provide a kind of version of concrete setting position of supporting construction, described plug is arranged on coupling element, and described catch and slot are all arranged on lower coupling element.
Further in order to strengthen and transmit the thrust in required direction when rain brush works to improve its transmission of power effect, described upper coupling element or lower coupling element are provided with blocking arm, and the blocking arm face of blocking arm is perpendicular to the swaying direction of rocking arm.
After have employed technique scheme, during installation, plug is inserted into slot position and in the below of catch, thus form a rotation shaft-like, through over-rotation, engagement section is snap-fited in cooperation stopper, by the cooperation of plug and slot, engagement section and coordinate the blocking arm of the cooperation of stopper and further both sides to connect together stable to rocking arm and rain brush securely, the retaining wall of both sides also plays to be strengthened and the thrust in direction needed for the work of transmission rain brush.
Accompanying drawing explanation
Fig. 1 is the assembling exploded view for the permanent joint mechanism between rain shaving blade and rocking arm of the present utility model.
Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of for the permanent joint mechanism between rain shaving blade and rocking arm, it is characterized in that, it comprises:
