Description

Technical Field

[0001] The utility model relates to the field of HDMI extension devices, in particular to an HDMI extension device. Background Art

[0002] HDMI extender is a device used to extend HDMI signals. It usually consists of a transmitter and a receiver, which are connected by a certain transmission medium. The original intention of the design of this device is to solve the problem that long-distance direct-connection cables cannot meet the transmission requirements, ensuring that the signal has no attenuation or has little attenuation during long-distance transmission, thereby ensuring high-quality transmission of images and sounds. It is widely used in multimedia exhibition halls, and can transmit video and audio signals to different digital screens to meet the needs of large digital walls or digital screens in different areas.

[0003] The Chinese patent document with authorization announcement number CN220401812U proposes an HDMI extender with adsorption function, including a frame, a first magnetic block and a second magnetic block; the frame is fixedly connected to the first magnetic block, and the frame is fixedly connected to the second magnetic block.

[0004] In the above application, although the HDMI extender can be fixed and installed by magnetic attraction through the magnetic attraction characteristics of the first magnetic block and the second magnetic block, making the installation more convenient, no cable limit device is set. Since there are many people and it is messy in the multimedia exhibition hall, people are likely to pull the cables when walking, causing the cables to loosen or even fall off the HDMI extender, thereby interrupting the multimedia playback. Utility Model Content

[0005] In view of the problems existing in the background technology, an HDMI extension device is proposed.

[0006] The utility model provides an HDMI extension device, which cooperates with a cable, and one end of the cable is provided with a plug connector. The HDMI extension device comprises an extender body. One side of the extender body is provided with a plug interface for plugging with the plug connector. A clamping assembly is arranged on the side of the extender body provided with the plug interface, and clamps the cable. And a limiting assembly is connected to the extender body at one end and to the clamping assembly at the other end, and the cable is limited by limiting the clamping assembly.

[0007] Preferably, two groups of snap-in assemblies are horizontally symmetrically arranged; the snap-in assemblies include a sleeve; the opposite ends of the sleeves on both sides are open, and a sliding plate is slidably connected to the opening; a spring is connected between the sleeve and the sliding plate, and a sliding groove is also provided on the side wall of the sleeve; a pulling column arranged on the sliding plate is slidably connected to the sliding groove; the opposite ends of the sliding plates on both sides are connected to the snap-in plates.

[0008] Preferably, one of the card-connecting plates is provided with an inserting block, and the other card-connecting plate is provided with a slot; the inserting block and the slot are engaged with each other.

[0009] Preferably, the two clamping plates are in a trumpet shape when clamped together.

[0010] Preferably, two groups of limit assemblies are horizontally symmetrically arranged; the limit assemblies include a second sleeve arranged on the side wall of the extender body; a second slide groove is opened on the side wall of the second sleeve, one end of the second sleeve is open away from the extender body, and a sliding column is slidably connected to the opening; a sliding block slidably connected to the second slide groove is provided at one end of the sliding column, and the other end is connected to the first sleeve; a fixed block is also provided between the second sleeve and the first sleeve; a second spring is connected between the fixed block and the sliding block.

[0011] Preferably, a suction cup is provided on the top / bottom of the extender body.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] (1) The HDMI extension device slides the pull posts on both sides toward each other, so that the plug block and the slot are docked, and the two clamping plates clamp the cable from both sides. The cable can be positioned, thereby greatly reducing the risk of the cable falling off the extender body due to external force. At the same time, since the position of the extender body and the cable is relatively stable, there is no need to repeatedly plug and unplug the connector when moving the extender body, ensuring the continuity of multimedia playback.

[0014] (2) The HDMI extension device pushes the sliding block and the sliding column to slide along the second slide groove toward the extender body through the second spring, so that the clamping plate squeezes the plug connector against the side wall of the extender body, further limiting the position of the cable, thereby preventing the cable from loosening due to external force. The stable connection between the plug connector and the extender body helps to maintain the stability of the circuit, thereby avoiding affecting the normal use of the electrical appliance. In addition, the stable connection can also reduce the wear on the plug interface and the plug connector itself caused by frequent plugging and unplugging or loosening of the plug connector, thereby extending their service life.

DETAILED DESCRIPTION

[0020] like Figure 1-4 As shown, the utility model proposes an HDMI extension device, which cooperates with a cable 2, and a plug connector 201 is provided at one end of the cable 2. The HDMI extension device includes an extender body 1, a clamping assembly 3 and a limiting assembly 4. One side of the extender body 1 is provided with a plug interface that cooperates with the plug connector 201. The clamping assembly 3 is arranged on the side of the extender body 1 where the plug interface is provided, and clamps the cable 2. One end of the limiting assembly 4 is connected to the extender body 1, and the other end is connected to the clamping assembly 3. By limiting the clamping assembly 3, the cable 2 is limited.

[0021] Further explanation, the clamping assembly 3 is horizontally symmetrically arranged in two groups; the clamping assembly 3 includes a sleeve 1 31; the opposite ends of the sleeve 1 31 on both sides are open, and the openings are slidably connected with a sliding plate 32; a spring 1 33 is connected between the sleeve 1 31 and the sliding plate 32, and a sliding groove 1 34 is also provided on the side wall of the sleeve 1 31; a pulling column 35 arranged on the sliding plate 32 is slidably connected to the sliding groove 1 34; the opposite ends of the sliding plates 32 on both sides are connected with a clamping plate 36. One of the clamping plates 36 is provided with an insert block 3601, and the other clamping plate 36 is provided with a slot 3602; the insert block 3601 and the slot 3602 are mutually engaged and clamped; the two clamping plates 36 can be prevented from being misaligned with each other. The two clamping plates 36 can clamp the cable 2 from both sides to position the cable 2, thereby greatly reducing the risk of the cable 2 falling off the extender body 1 due to external force. At the same time, since the positions of the extender body 1 and the cable 2 are relatively stable, there is no need to repeatedly plug and unplug the plug connector 201 when moving the extender body 1, thereby ensuring the continuity of multimedia playback.

[0022] Further, the two clamping plates 36 are horn-shaped when clamped together. When the cable 2 is bent due to external force, the cable 2 will fit on the arc-shaped inner wall of the clamping plate 36, so that the bending angle of the cable 2 will not be too large, thereby reducing the risk of the cable 2 breaking.

[0023] Further explanation, the limiting assembly 4 is horizontally symmetrically arranged in two groups; the limiting assembly 4 includes a sleeve 2 41 arranged at the side wall of the extender body 1; a slide groove 2 43 is opened at the side wall of the sleeve 2 41, and the sleeve 2 41 is opened at one end away from the extender body 1, and a sliding column 42 is slidably connected to the opening; one end of the sliding column 42 is provided with a sliding block 45 slidably connected to the slide groove 2 43, and the other end is connected to the sleeve 1 31; the sleeve 2 41 is also provided with a fixed block 44 between the sliding block 45 and the sleeve 1 31; a spring 2 46 is connected between the fixed block 44 and the sliding block 45. The plug connector 201 is squeezed at the side wall of the extender body 1 by the clamping assembly 3, so as to further limit the cable 2 and prevent the cable 2 from loosening due to external force. The stable connection between the plug connector 201 and the extender body 1 helps to maintain the stability of the circuit and avoid voltage fluctuations or current instability caused by the loosening of the plug connector 201, thereby affecting the normal use of the electrical appliance. In addition, the stable connection can also reduce the wear on the plug interface and the plug connector 201 itself caused by frequent plugging and unplugging or loosening of the plug connector 201, thereby extending their service life.

[0024] Further explanation, a suction cup 5 is provided on the top / bottom of the extender body 1. The extender body 1 can be adsorbed and installed at any position, which improves the stability of the extender body 1 and is convenient and quick to install.

[0025] The working principle of the utility model is as follows: when working, first insert the plug connector 201 on the cable 2 into the plug interface. Then pull the pulling columns 35 on both sides to slide towards each other, so that the plug block 3601 and the slot 3602 are docked, so that the two clamping plates 36 clamp the cable 2 from both sides. The spring 1 33 can further improve the stability of the clamping of the two clamping plates 36. After letting go, the spring 2 46 will push the sliding block 45 and the sliding column 42 to slide along the sliding groove 2 43 toward the direction of the extender body 1, so that the clamping plate 36 squeezes the plug connector 201 at the side wall of the extender body 1, further limiting the cable 2 to prevent the cable 2 from loosening due to external force.

[0026] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
