Description

Technical Field

[0001] The utility model specifically relates to an air guide structure of a set-top box, belonging to the technical field of set-top boxes. Background Art

[0002] A digital video converter box, commonly known as a set-top box or set-top box, is a device that connects a television set to an external signal source. It can convert compressed digital signals into television content and display them on the television set. The signals can come from cable, satellite antenna, broadband network, and terrestrial broadcasting. In addition to the images and sounds that analog television can provide, the set-top box can also receive digital content, including electronic program guides, Internet pages, subtitles, etc., allowing users to watch digital television programs on existing televisions and conduct interactive digital entertainment, education, and commercial activities through the Internet.

[0003] When the existing set-top box is used in the high temperature season in summer, the set-top box generates temperature inside due to its fixed structure and poor ventilation and heat dissipation effect, which in turn affects the service life of the set-top box. When the existing set-top box dissipates heat, it usually dissipates heat inside the set-top box through a heat dissipation hole on one side of the set-top box. This process cannot increase the heat dissipation and ventilation area of ​​the set-top box, so the above existing devices still need to be improved.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0009] Furthermore, in order to enable the pushing rod to rise through the Y-shaped stretching rope when the pressing rod moves downward, and at the same time the elastic force of the pressing spring is greater than the total elastic force of the symmetrically arranged pushing springs, a Y-shaped stretching rope is arranged on the surface of one end of the pressing rod, and both ends of the Y-shaped stretching rope below symmetrically penetrate the inner wall of the lower end of the pressing sleeve, and both ends of the Y-shaped stretching rope below extend through the outer walls of the pushing sleeve at both ends of the inner bottom wall of the set-top box base and are fixedly installed on one end of the pushing rod.

[0010] Furthermore, in order to facilitate the staff to insert the card block into the convex groove and thus achieve the limiting effect of the pressing rod, the upper end of the pressing rod passes through the outer top wall of the set-top box cover, and the card block is rotatably installed on the upper end of the pressing rod. A convex groove is provided on the inner wall of the top surface of the set-top box cover, and the card block is located above the convex groove.

[0011] Furthermore, in order to fix the winding box, the anti-folding winding assembly includes a winding box, and both ends of the top wall of the winding box are fixedly welded with fixing plates, and the fixing plates are connected to the inner top wall of the set-top box cover by screws.

[0012] Furthermore, in order to realize automatic rotation of the winding drum by the winding spring, a winding drum is rotatably installed in the winding box, a winding spring is arranged in the winding drum, one end of the winding spring and an inner wall of one end of the winding box are fixedly connected to each other, the other end of the winding spring and an inner wall of one end of the winding drum are fixedly connected to each other, and the breathable film is wrapped and laid on the outer surface of the winding drum.

[0013] Furthermore, in order to shield the set-top box cover and the four corners of the set-top box base, thereby reducing the amount of dust entering the set-top box base, plug-in blocks are provided at the four corners of the lower end surface of the set-top box cover, and L-shaped plug-in slots are provided at the four corners of the top end of the set-top box base. The plug-in block is plugged into the L-shaped plug-in slot, and limiting slots are provided at both ends of the L-shaped plug-in slot. Limiting blocks are provided at both ends below the plug-in block, and the limit blocks and the limit slots are slidably engaged with each other.

[0014] The beneficial effect of the utility model is that when the weather is hot or the set-top box is overheated, the device can separate the set-top box cover from the set-top box base by using a manual quick lifting component, and then use a breathable membrane to provide dust-proof shielding on the four sides, thereby increasing the ventilation volume in the set-top box base, thereby improving the heat dissipation effect of the device, and the device has a sophisticated structure and outstanding practical value.

Both ends of the Y-shaped stretching rope 407 symmetrically penetrate the inner wall of the lower end of the pressing sleeve 402, and both ends of the Y-shaped stretching rope 407 extend through the outer wall of the pushing sleeve 401 at both ends of the inner bottom wall of the set-top box base 1 and are fixedly installed at one end of the pushing rod 403. The upper end of the pressing rod 405 penetrates the outer top wall of the set-top box cover 2. A clamping block 6 is rotatably installed on the upper end of the pressing rod 405. A convex groove 7 is provided on the inner wall of the upper top surface of the set-top box cover 2. The clamping block 6 is located above the convex groove 7, so that the staff can press the pressing rod 405 downward to drive the upper end of the Y-shaped stretching rope 407 to move downward through the pressing rod 405. At this time, the lower ends of the Y-shaped stretching rope 407 respectively move the pushing rod 403 upward under the action of the pushing spring 404, and the set-top box cover 2 is moved upward.

[0026] like Figure 1-Figure 3As shown, the anti-folding winding assembly 5 includes a winding box 501, both ends of the top wall of the winding box 501 are fixedly welded with fixing plates 502, the fixing plates 502 are connected to the inner top wall of the set-top box cover 2 by screws 503, a winding drum 504 is rotatably installed in the winding box 501, and a winding spring 505 is arranged in the winding drum 504, one end of the winding spring 505 is fixedly connected to the inner wall of one end of the winding box 501, and the other end of the winding spring 505 is fixedly connected to the inner wall of one end of the winding drum 504, the breathable film 3 is wrapped and laid on the outer surface of the winding drum 504, and the bottom of the set-top box cover 2 Plug-in blocks 8 are provided at the four corners of the end surface, and L-shaped plug-in grooves 9 are provided at the four corners of the top of the set-top box base 1.
