Referring to fig. 1 to 4, the mask ear band clamp device of the present invention is made as follows:
a mask ear belt line clamping device comprises a plate-shaped base 100, wherein four steel ball mounting holes 110 are formed in the base 100, and the steel ball mounting holes 110 penetrate through the base 100 in the vertical direction. The steel ball mounting hole 110 is internally provided with a spherical steel ball 400, and the steel ball 400 is made of stainless steel.
The bottom of base 100 is equipped with two shell fragment mounting grooves, fixed mounting has shell fragment 200 in the shell fragment mounting groove, the middle part of shell fragment 200 with base 100 fixed connection, two are located respectively at the both ends of shell fragment 200 the downside of steel ball mounting hole 110.
A pressing block 300 is arranged above the steel ball mounting hole 110, the middle part of the pressing block 300 is hinged with the base 100 and is provided with a protruding part 330, and the two sides of the hinged position are respectively provided with a clamping part 310 and a reset pressing part 320. The steel ball 400 is clamped between the protrusion 330 and the spring plate 200.
Referring to fig. 1 to 4, in the process of using the ear band clamp device for mask of the present invention: by pressing the reset pressing part 320 of the pressing block 300, the pressing block 300 which originally keeps the clamping state can be changed into an open state and kept; by pressing the clamping portion 310 of the pressing block 300, which is originally kept in the open state, can be brought into a clamped state and held.
Specifically, the method comprises the following steps: referring to fig. 4, the elastic force of the elastic sheet 200 is transmitted to the protrusion 330 of the pressing member 300 through the steel ball 400, and the pressing member 300 is in an open state, and the clamping portion 310 of the pressing member is kept to be turned and lifted outwards by the steel ball 400. When the clamping portion 310 is pressed downward by an external force, the protrusion 330 presses the steel ball 400 to move downward and bend and deform the resilient piece 200 downward during the swinging of the pressing block 300. Referring to fig. 2, after the clamping portion is pressed to a certain position, a contact point between the protrusion 330 and the steel ball 400 moves from one side of the protrusion 330 to the other side, and the steel ball 400 always keeps a tendency of moving upward under the elastic force of the elastic sheet 200, so that the clamping portion 310 keeps inward turning and pressing under the action of the steel ball 400, that is, keeps a clamping state. Similarly, for the pressing block 300 in the clamping state, the pressing part 300 is turned and lifted outwards by pressing the reset pressing part 320 of the pressing block 300, and the pressing block 300 is kept in the open state when the steel ball 400 acts on the other side of the protrusion 330.
In some embodiments, the number of the spring pieces 200 is the same as that of the steel ball mounting holes 110, and each steel ball mounting hole 110 corresponds to one spring piece 200.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
