Description

Technical Field

[0001] The utility model relates to the technical field of projectors, in particular to a projector with an extended function interface. Background Art

[0002] During the use of existing projectors, they need to be used in conjunction with corresponding content source devices. The general form is to provide various input and output interfaces on the projector, requiring users to connect personal computers, wireless projection TV sticks, network media players, high-definition digital media players, digital TV set-top boxes and other devices to the corresponding audio and video input interface sockets of the projector through various connecting cables. As the functions of projectors are gradually enriched, the number of traditional functional interfaces is difficult to meet the needs. The existing method is to adaptively increase the number of interfaces on the rear side of the projector, but the existing projectors still have the following deficiencies in actual use:

[0003] The setting of the newly added functional interface peripherals of the existing projector not only reduces the design space of other functions of the projector, but also easily causes damage to the functional interface, thus affecting the normal use of the functional interface;

[0004] To this end, we propose a projector with an extended function interface to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a projector with an extended function interface to solve the problem that the projector's extended interface peripherals are prone to interface damage.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a projector with an extended function interface, comprising: an instrument housing, a guide port is provided on the instrument housing, an extension module is slidably provided on the inner side of the guide port, and extension interfaces are provided on both sides of the extension module.

[0007] Preferably, a connecting column is provided on the expansion module, and a limiting block is provided at one end of the connecting column.

[0008] Preferably, a guide block is provided on the inner side of the instrument housing, and a connecting column is slidably provided on the inner side of the guide block.

[0009] Preferably, positioning magnets are symmetrically mounted on the inner wall of the guide opening, and the positioning magnets are connected to the expansion module.

[0010] Preferably, a dustproof plate is connected to the rotating shaft on the instrument housing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The expansion module of the utility model is slidably arranged on the inner side of the instrument housing, and is pulled out when in use and inserted when not in use, thereby preventing the expansion interface from being exposed to the outside, being damaged by collisions, and being infiltrated by dust.

[0014] Figure 2 This is a schematic diagram of the expansion module of the utility model;

[0015] In the figure: 1 instrument housing, 11 guide block, 12 guide port, 13 positioning magnet, 14 dust plate, 2 extension module, 21 connecting column, 211 limit block, 22 extension interface. DETAILED DESCRIPTION

[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.

[0017] See also Figure 1 and Figure 2 The projector with an extended function interface shown in the figure includes: an instrument housing 1, a guide port 12 is arranged on the instrument housing 1, an extension module 2 is slidably arranged on the inner side of the guide port 12, and extension interfaces 22 are arranged on both sides of the extension module 2. The extension module 2 is slidably arranged on the inner side of the instrument housing 1, and is pulled out when in use and inserted when not in use, so as to prevent the extension interface 22 from being exposed to the outside and being damaged by bumps and dust from entering.

[0018] The expansion module 2 is provided with a connecting column 21 , and a limiting block 211 is provided at one end of the connecting column 21 . The limiting block 211 abuts against the guide block 11 to prevent the expansion module 2 from being drawn out of the instrument housing 1 .

[0019] A guide block 11 is provided inside the instrument housing 1 , and a connecting column 21 is slidably provided inside the guide block 11 . When the expansion module 2 moves along the guide opening 12 , the connecting column 21 can drive the connecting column 21 to move along the guide block 11 .

[0020] Positioning magnets 13 are symmetrically mounted on the inner wall of the guide opening 12 . The positioning magnets 13 are connected to the extension module 2 . The extension module 2 is positioned by adsorbing the extension module 2 by the positioning magnets 13 .

[0021] A dustproof plate 14 is connected to the rotating shaft on the instrument housing 1. When the projector is not in use, the expansion module 2 is moved to the inside of the instrument housing 1. The expansion module 2 is shielded by the dustproof plate 14 to prevent dust from entering the interface of the expansion module 2.

[0022] In this embodiment, the expansion module 2 is slidably arranged on the inner side of the instrument housing 1. When in use, it is pulled out to expose the expansion interface 22 for connection. When not in use, the expansion module 2 is inserted into the inner side of the instrument housing 1 and then shielded from dust by the dustproof plate 14, thereby preventing the expansion interface 22 from being exposed to the outside and being damaged by collisions and dust from entering.
