Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical modem, specifically relates to a suspension type optical modem. BACKGROUND

[0002] Optical modem refers to a fiber modem, which is a device for realizing network connection through optical fiber, usually installed in a home environment or enterprise office environment, and used as a bridge between the optical fiber network and the user terminal device. At present, due to the arrangement requirements or space limitations of hot spots, there is a demand for installing optical modem on the wall, therefore, it is necessary to set up an installation structure that can suspend the optical modem.

[0003] For example, the utility model patent with publication number CN221900965U discloses a suspension type optical modem, which can be suspended on hanging structures such as hanging racks, bookshelves, and cup holders through a suspension assembly. The suspension type optical modem specifically includes an optical modem shell, a communication assembly, a suspension assembly, and a limiting assembly. The optical modem shell forms an accommodation cavity inside, and is provided with a rear shell surface and a front shell surface facing each other. The suspension assembly is arranged outside the rear shell surface and includes an extension rod that passes through the rear shell surface and extends into the accommodation cavity. The limiting assembly includes a limiting rod and a locking rod, and the limiting rod is provided with a first limiting hole corresponding to the position of the extension rod. The utility model can be suspended on hanging structures such as hanging racks, bookshelves, and cup holders through the suspension assembly. The extension rod can slide relative to the first limiting hole, so that the distance between the suspension assembly and the rear shell surface can be adjusted to match different sizes of hanging structures and avoid affecting the installation of the optical modem shell. Then, the user can adjust the locking rod on the front shell surface of the optical modem shell to lock the extension rod and the limiting rod by applying force to the limiting rod with the locking rod, thereby completing the installation of the suspension type optical modem. Through the above arrangement, the flexibility of the suspension type optical modem is improved under the premise of facilitating user installation.

[0004] However, since the extension rod of the suspension assembly in the utility model needs to pass through the rear shell surface, it not only occupies the internal space of the optical modem shell, but also makes it inconvenient to produce the optical modem shell separately, resulting in high production cost and making it difficult to disassemble the suspension assembly from the optical modem shell. Therefore, the optical modem can only be suspended, which cannot meet the needs of users who want to place the optical modem horizontally according to different scenarios. UTILITY MODEL CONTENTS

[0005] To solve the above problems in the prior art, the utility model provides a suspension type optical modem, which solves the problem of inconvenient disassembly and high production cost caused by the integral arrangement of the optical modem shell and the suspension assembly.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hanging optical cat is provided, comprising: an optical cat main body, the optical cat main body comprising a shell, at least two rows of round head studs and two rows of clamping heads being symmetrically arranged on the bottom surface of the shell along a center line; and a hanging rack, the hanging rack comprising a bottom plate, two U-shaped plates being integrally formed on both sides of the bottom plate, a row of locking holes for detachable connection with the round head studs and a row of clamping holes for clamping connection with the clamping heads being formed on the end plate of each U-shaped plate, and at least two connection grooves for bolt connection with a hook or screw connection with a hanging screw being symmetrically arranged on the end surface of the bottom plate along the center line.
