Technical Field
[0001] This application belongs to the field of adapter technology, specifically a power adapter for a projector. Background Technology
[0002] A power adapter is an electronic device that converts alternating current (AC) to direct current (DC) or converts one voltage and current specification to another to meet the needs of a device. A power adapter is not just a simple "plug converter", but a key component that integrates power conversion, safety protection and energy efficiency management. Depending on its function, purpose and output voltage and current, power adapters can be divided into many types.
[0003] However, in common applications of this technology, excessively long cables are inconvenient to install and use during the use of projector power adapters, reducing their aesthetics. Excessively long cables can also cause them to become tangled and knotted, making it difficult for users to install and store them later. Utility Model Content
[0004] The purpose of this application is to provide a power adapter for a projector in order to solve the problems mentioned above.
[0005] The technical solution adopted in this application is as follows: A power adapter for a projector includes a power adapter, a cable take-up compartment fixedly installed on the lower surface of the power adapter, a storage shell provided on the upper surface of the cable take-up compartment, an inner cavity opened inside the storage shell, a take-up roller provided at the center of the inside of the cable take-up compartment, a take-up groove provided on the surface of the take-up roller, a sealing head installed on the inner right side surface of the cable take-up compartment, a base cover fixedly connected to the right side of the sealing head, a through hole provided on the outer lower surface of the cable take-up compartment, a power supply cable connected to one side of the through hole, and a power connector installed at one end of the power supply cable.
[0006] By adopting the above technical solution, the power adapter cable can be stored in the cable take-up compartment, which hides the cable inside, preventing it from getting tangled and improving overall aesthetics and convenience. The inner cavity of the storage housing prevents the cable from being exposed due to excessive length and also prevents the cable from sagging during use, improving durability and safety.

The sealing head holds the take-up roller inside the cavity, preventing it from rotating unexpectedly in a stable state, ensuring the cable maintains the adjusted length during use, improving stability and integrity.
[0007] In a preferred embodiment, the upper surface of the take-up compartment is provided with heat dissipation holes, and a dustproof mesh is provided inside the heat dissipation holes.
[0008] By adopting the above technical solution, the internal temperature of the cable take-up compartment can be kept very stable by installing heat dissipation holes, thereby protecting the internal cables. By installing a dustproof net, dust can be prevented from falling into the cable take-up compartment through the heat dissipation holes, improving the internal hygiene and cleanliness, and making it safe and tidy.
[0009] In a preferred embodiment, a power adapter cable terminal is provided on the lower center surface of the power adapter, and rubber pads are installed on both sides of the power adapter.
[0010] By adopting the above technical solution, the installation of rubber pads makes it easier to adjust the position during use, provides a more stable grip, and prevents damage caused by the power adapter potentially falling to the ground, thus improving safety and convenience.
[0011] In a preferred embodiment, the power adapter has a second opening at its top, and a plug is mounted on the inner surface of the second opening.
[0012] By adopting the above technical solution, the ventilation of the plug can be increased by setting a second opening, which can prevent the plug from generating high temperatures during use, thereby preventing damage to the power adapter and making it stable and reliable.
[0013] In a preferred embodiment, the plug has a first wiping oil on both sides, a free end is installed inside the first wiping oil, and a rotating end is provided at the front end of the free end.
[0014] By adopting the above technical solution, the user can adjust the direction of the plug according to the needs of the user by setting a rotating end and a free end, which facilitates insertion and removal, thereby improving the user's convenience and adaptability.
[0015] In a preferred embodiment, a connection port is fixedly mounted on the top of the power adapter, and a connection cable is provided on the inner surface of the connection port.
[0016] By adopting the above technical solution, the connection cable can be more stably connected to the power adapter and plug by installing the connection port. The connection cable allows the user to adjust the length of the plug, avoiding the problem of insufficient length preventing connection to the socket, thus improving stability and versatility.
[0017] In a preferred embodiment, the plug has grooves on both sides and a locking protrusion on the right side of the groove.
[0018] By adopting the above technical solution, the installation of the sliding groove can make the plug move more smoothly, and the locking protrusion can ensure the accuracy during the installation process, thus improving its stability and installation accuracy.
[0019] In a preferred embodiment, slots are provided on the upper surfaces of both sides of the second opening, and a protruding ridge is provided on the right side surface of the slots.
[0020] By adopting the above technical solution and setting the concave-convex structure of the slot and ridge, a strong frictional force can be generated during the connection process, thereby improving the stability of the connection and giving it better fixation.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0022] In this application, a cable retractor can be installed to store the power adapter cable, allowing the cable to be hidden inside the retractor. This prevents the cable from getting tangled during use, improving overall aesthetics and convenience. The inner cavity of the retractor prevents the cable from being exposed due to excessive length and also prevents the cable from sagging during use, improving durability and safety. The retractor roller has a retracting groove on its surface to retract the cable and adjust its length, providing convenience and versatility for the user and improving adaptability during installation. The sealing head holds the retractor roller inside the cavity to prevent accidental rotation of the retractor roller in a stable state, ensuring that the cable maintains the adjusted length during use, improving stability and integrity.
