Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens accessories, and in particular relates to a lens cover that is automatically opened by pressing. Background Art

[0002] The optical lens is a key component of optical instruments such as cameras, camcorders, and telescopes, and is also one of the core components of the optical imaging system. Its main function is to convert the target object into an image through the optical imaging system and transmit it to the receiver (such as camera sensor, human eye, etc.) for recording or observation. The optical lens is usually composed of optical elements such as lenses, reflectors, and filters. These elements can change the direction of light propagation, focus light, filter light, etc., to obtain clearer and more accurate images.

[0003] Optical lens accessories are also used to assist optical lenses, including lens covers for optical lenses, which are devices used to protect lenses. However, in actual applications, traditional lens covers cannot be opened and used quickly and conveniently, making operation inconvenient and poorly practical.

[0004] Therefore, it is necessary to provide a lens cover that can be automatically opened by pressing, so as to effectively improve the above problems. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the utility model provides a lens cover that can be automatically opened by pressing, which has the characteristics of being able to automatically open by pressing and being more convenient to open and use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lens cover that is automatically opened by pressing, comprising a front lens cover, a lens cover mounting ring, a lens cover paddle, a compression spring and a torsion spring, wherein the compression spring and the lens cover paddle are installed on the front lens cover, a hook is fixed on the inner side of the lens cover paddle, and the lens cover mounting ring is provided on one side of the front lens cover, and the lens cover paddle is pressed to compress the compression spring so that the hook of the lens cover paddle is separated from the lens cover mounting ring, thereby facilitating the opening operation of the front lens cover, and the intersection of the lens cover mounting ring and the top end of the front lens cover is connected through a pin shaft and the torsion spring.

[0007] As a preferred technical solution for automatically opening the lens cover by pressing the lens cover of the utility model, a linear groove is provided on the front lens cover at a position corresponding to the lens cover paddle, and the lens cover paddle can perform linear motion in the linear groove of the front lens cover.

[0008] As a preferred technical solution for automatically opening the lens cover by pressing the lens cover of the utility model, the hook is a folding block-shaped structure.

[0009] As a preferred technical solution for automatically opening the lens cover by pressing the lens cover of the utility model, the front lens cover, the lens cover paddle and the lens cover mounting ring are all ABS components.

[0010] Compared with the prior art, the utility model has the following beneficial effects: when in use, the utility model realizes the function of automatically opening by pressing through the torsion spring, and the opening angle of the lens cover is 240°;

[0011] The lens cover paddle is pushed by a compression spring to achieve a press-to-close function, wherein the front lens cover, lens cover paddle and lens cover mounting ring are made of ABS components, and the overall weight is not high. A double-mold processing method is adopted, which is simple to process, has low processing costs, a simple structure, is easy to operate, and has strong practicality. This solves the problem that the original lens cover cannot be opened and used quickly and conveniently in actual application, and is inconvenient to operate and has poor practicality.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0017] See also Figure 1 and Figure 2 The utility model provides the following technical solutions: a lens cover that is automatically opened by pressing (i.e., a lens cover structure), which comprises: a front lens cover 1, a lens cover mounting ring 4, a lens cover paddle 6, a compression spring 5, and a torsion spring 3, wherein the front lens cover 1, the lens cover paddle 6, and the lens cover mounting ring 4 are all ABS components, the overall weight is not high, and the manufacturing cost is low.

[0018] The first step is to install the lens cover, install the compression spring 5 on the front lens cover 1, and then install the lens cover paddle 6 (the compression spring 5 and the lens cover paddle 6 are installed on the front lens cover 1);

[0019] A hook is fixed on the inner side of the lens cover paddle 6 (the hook is a folded block structure), a lens cover mounting ring 4 is provided on one side of the front lens cover 1, and a linear groove is opened at a position corresponding to the lens cover paddle 6 on the front lens cover 1, so that the lens cover paddle 6 can make a linear motion in / at the linear groove of the front lens cover 1. When in the closed state, the hook on the lens cover paddle 6 is hung on the lens cover mounting ring 4.

[0020] The pin shaft 2 is installed on the lens cover mounting ring 4, and the torsion spring 3 and the front lens cover 1 are installed (the intersection of the lens cover mounting ring 4 and the top of the front lens cover 1 is connected through the pin shaft 2 and the torsion spring 3), wherein the lens cover mounting ring 4 is fixed, and the torsion spring 3 pushes the front lens cover 1 to rotate around the pin shaft 2 to form a lens cover.

[0021] The lens cover of the utility model has a function of automatically opening by pressing, which is convenient to open and use;

[0022] Furthermore, under normal circumstances, the lens cover is closed (such as Figure 1 As shown in FIG. 1 ), the closed state is achieved by connecting a compression spring 5 to the linear groove on the front lens cover 1, and connecting the other end of the compression spring 5 to the lens cover paddle 6. The compression spring 5 pushes the lens cover paddle 6 to move linearly in the linear groove of the front lens cover 1, so that the hook on the lens cover paddle 6 is hung on the lens cover mounting ring 4, thereby maintaining the closed state. Figure 1 As shown;

[0023] Lens cover opening process: Press the lens cover paddle 6 to compress the compression spring 5 (the compression spring 5 contracts and presses the lens cover paddle 6 to Figure 1 The torsion spring 3 shown in the figure moves in the direction of the torsion spring 3 to make the hook of the lens cover paddle 6 disengage from the lens cover mounting ring 4, which is convenient for the subsequent opening operation of the front lens cover 1. Then the torsion spring 3 pushes the front lens cover 1 to rotate around the pin shaft 2, thereby achieving the function of automatic opening, achieving Figure 2 The usage status shown is simple in structure and easy to operate;

[0024] The utility model has the advantages of simple processing, low processing cost, simple structure, convenient operation and strong practicality, and solves the problems that the original lens cover cannot be opened and used quickly and conveniently in actual application, and is inconvenient to operate and has poor practicality.
