Detailed Description

For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, fig. 1 is a schematic perspective view of an auxiliary pressing assembly according to an embodiment of the present invention, and fig. 2 is a front view of the auxiliary pressing assembly shown in fig. 1.

The embodiment of the utility model provides an auxiliary pressing component includes elasticity preforming 1 and screw 3, and wherein, the structure of elasticity preforming 1 is as shown in fig. 3 and fig. 4, and fig. 3 is the perspective schematic view of elasticity preforming 1, and fig. 4 is the elevation view of elasticity preforming 1. Specifically, the elastic pressing piece 1 is an integral structure, and includes a base portion 11 and a cantilever portion 12, wherein the base portion 11 is a flat plate, and the cantilever portion 12 is shaped to extend upward from a first side (a dotted line position in fig. 4) of the base portion 11, then extend toward the other side of the base portion 11 opposite to the first side, and finally reach an obliquely lower side of the base portion 11. As shown in fig. 3, the base portion 11 has a first hole (not shown) for inserting a screw therethrough, and the cantilever portion 12 has a second hole (not shown) for inserting a driver therethrough.

As can be seen from fig. 1 and 2, the screw 3 is inserted into the first hole of the elastic pressing plate 1, the head of the screw 3 is located in the space enclosed by the base portion 11 and the cantilever portion 12, and the opening of the second hole of the elastic pressing plate 1 is located along the second hole to restrict the passage of the head of the screw 3, i.e., the screw 3 cannot be detached from the elastic pressing plate 1. In the manufacturing process of the auxiliary pressing assembly, the step of forming the elastic pressing sheet 1 is later than the step of assembling the screw 3 with the first hole, that is, the screw 3 is inserted into the first hole of the base portion 11, and then the cantilever portion 12 is bent into the shape shown in fig. 4. It should be understood that the space enclosed by the base portion 11 and the cantilever portion 12 does not limit the rotation of the head of the screw 3.

Referring to fig. 2, the auxiliary pressing assembly works on the principle that the screw 3 fixes the elastic pressing sheet 1 on a structural member for carrying a pressed object, and the end of the elastic pressing sheet 1 is used for pressing and fixing the pressed object (such as a lens, etc.). Since the screw 3 cannot be detached from the elastic pressing piece 1, that is, the two are always assembled together, when the lens is installed by using the elastic pressing piece, the trouble of assembling the elastic pressing piece 1 and the screw 3 on site is eliminated, which is helpful for improving the installation efficiency of the lens.

Referring to fig. 4, the cantilever portion 12 extends reversely above the base portion 11, and the sufficient cantilever length is ensured on the premise of not increasing the two-dimensional plane size, so that the utility model provides an elastic pressing sheet is favorable for the miniaturization design of the product.

The auxiliary compression assembly may further include a washer 2 fitted over the screw 3, as shown in fig. 2, the washer 2 being located between the head of the screw 3 and the base portion 11. In a specific practical application, the washer 2 may be a spring washer, and the screw 3 may be a countersunk head screw or a pan head screw.

In order to prevent the surface of the pressed object such as a lens from being scratched, the end of the base portion 11 is usually passivated, for example, in the present embodiment, the end of the base portion 11 has a curled edge 121 formed by upward rolling, as shown in fig. 4.

In a specific practical application, the material of the elastic pressing sheet 1 is generally stainless steel or plastic, the second hole of the elastic pressing sheet 1 may be a kidney-shaped hole, and the end of the cantilever portion 12 close to the base portion 11 is preferably circular arc-shaped.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
