Description

Technical Field

[0001] This utility model relates to the field of household appliance accessories technology, and in particular to an anti-displacement structure for set-top boxes. Background Technology

[0002] Currently, set-top boxes commonly used in homes are typically placed directly on TV cabinets or other flat surfaces. Due to their lightweight nature and usually smooth plastic bottoms with low friction, they are prone to displacement or even slipping off the surface when connected to multiple cables (such as HDMI cables, audio / video cables, power cables, and network cables). This displacement can lead to loosening of the set-top box's interfaces and cable connections, causing unstable or interrupted signal transmission and affecting the user's viewing experience. It can also result in damage to the device if it falls, causing unnecessary financial losses. Furthermore, some cable connectors (such as HDMI connectors) are delicate, and frequent plugging and unplugging or uneven stress can easily damage the interface. Therefore, an anti-displacement structure for the set-top box is needed to meet this requirement. Utility Model Content

[0003] The purpose of this invention is to provide an anti-offset structure for a set-top box to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-displacement structure for a set-top box, comprising a support frame for placing the set-top box and the set-top box body itself. Four feet are fixedly provided at the bottom of the set-top box body, typically located at the four corners of the bottom of the set-top box. Each foot has a recessed block fitted from bottom to top at its bottom end, forming a connection by fitting the recessed block around the foot from below.

[0005] The support frame is internally equipped with a set of lateral adjustment mechanisms and a set of longitudinal adjustment mechanisms. These two sets of adjustment mechanisms are arranged vertically in a staggered manner in space, without interfering with each other. The lateral and longitudinal adjustment mechanisms have the same core components: each includes a bidirectional screw rotatably connected to the inner wall of the support frame, two parallel moving rods connected to the bidirectional screw via threaded transmission, the two moving rods being located on opposite threaded sections of the bidirectional screw, and a first knob for connecting and driving the bidirectional screw to rotate. This first knob is located on the outside of the support frame for easy operation.

[0006] Each movable rod has a guide groove along its length. A guide block is fixedly connected to the bottom end of each grooved block. Crucially, each guide block slides into the guide grooves of two movable rods that are vertically staggered at corresponding positions. Specifically, a guide block simultaneously embeds into the guide grooves of one lateral adjustment mechanism movable rod and one longitudinal adjustment mechanism movable rod. The coordinated movement of these two vertically moving rods precisely controls the position of the guide block in the horizontal plane.

[0007] Preferably, to enhance the stability of the moving rod during movement and prevent it from deflecting as the bidirectional screw rotates, the lateral adjustment mechanism and the longitudinal adjustment mechanism further include guide rods. The guide rods are arranged symmetrically and parallel to the bidirectional screw, with both ends fixedly connected to the inner sidewalls of the support frame. The moving rod is typically connected to both the bidirectional screw and the guide rods simultaneously. The guide rods provide guidance and support, ensuring that the moving rod only performs linear motion.

[0008] Preferably, to prevent the guide block from detaching from the guide groove, a limiting block is provided at the bottom end of the guide block. The perimeter of the limiting block is larger than the perimeter of the guide block, and also larger than the width of the guide groove. The limiting block is arranged at the lower part of the guide groove of the lower set of adjustment mechanisms (longitudinal adjustment mechanisms), thereby confining the guide block within the guide groove.

[0009] Preferably, a support plate is movably connected to the bottom end of the support frame near the set-top box interface via two lugs and a shaft. This support plate can rotate around the shaft. Several screws arranged in a matrix are threaded onto the side of the support plate near the inner side of the support frame (i.e., the side facing away from the set-top box). Each screw has a second knob on its inner end for easy manual tightening. Several rubber sleeves are provided on the side of the support plate near the outer side of the support frame (i.e., the side facing away from the set-top box), each sleeve fitting onto the corresponding screw segment extending outwards from the support plate. To facilitate adaptability to different placement positions during use, when the support plate is rotated to a horizontal position, the support frame can be placed on a table; when rotated to a vertical position, the support plate can be inserted into the gap between the TV cabinet and the wall, or placed above the top of the LCD TV, greatly improving adaptability.

[0010] Preferably, to improve the stability of the support plate in a vertical position, a slot is provided at the bottom end of the support frame. When the support plate is rotated downwards to a vertical position, its top end can be inserted into the slot to fix the angle. The two ends of the support plate near the top end have communicating straight slots, and the shaft is movably connected within these slots. The straight slots allow the support plate to move up and down along the shaft when needed, facilitating the alignment and insertion of its top end into the slot, or its disengagement from the slot.

[0011] Preferably, to ensure the stability of the support plate in a horizontal state and prevent it from sagging or rotating when lifted, magnets are provided on the bottom of the support frame away from the hinge end of the support plate and on the bottom of the support plate near the inner side of the support frame. When the support plate is horizontal, these two magnets attract each other, serving to assist in positioning and prevent accidental rotation of the support plate.

[0012] The beneficial effects of this utility model are: In this invention, the combination of four sets of guide blocks and a bidirectional screw-driven moving rod guide groove can firmly fix the bottom of the set-top box at four points, preventing it from moving arbitrarily in the horizontal plane. This effectively resists cable pulling and daily collisions, while avoiding contact with the outside of the set-top box body, ensuring the overall aesthetics of the set-top box body, and preventing damage to the set-top box body.

[0013] In this invention, by rotating the two first knobs, the horizontal and vertical positions of the set-top box on the support frame can be adjusted independently, thereby adapting to the foot spacing of set-top boxes of different sizes and making it easy to adjust the set-top box to the optimal position on the support frame, thus having good versatility.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-8 An anti-displacement structure for a set-top box includes a set-top box body 1 and a support frame 2. The support frame 2 is preferably made of metal or high-strength engineering plastic and has sufficient structural strength to support the set-top box.

[0018] The four corners of the bottom of the set-top box body 1 are usually provided with protrusions for support or installation, which are collectively referred to as feet 3 in this embodiment. On each foot 3, a recessed block 4 is fitted from bottom to top. The groove shape at the top of the recessed block 4 matches the foot 3.

[0019] Inside the cavity of the support frame 2, there is a set of lateral adjustment mechanisms 5 and a set of longitudinal adjustment mechanisms 6. The lateral adjustment mechanism 5 is located on the upper layer, and the longitudinal adjustment mechanism 6 is located on the lower layer. The two are staggered vertically by brackets or partitions inside the support frame 2, and do not interfere with each other.

[0020] The lateral adjustment mechanism 5 includes: a bidirectional screw 7, whose two ends are rotatably connected to the left and right inner sidewalls of the support frame 2 via bearings or bearing seats; two movable rods 8, which engage with the corresponding threaded sections of the bidirectional screw 7 through internally machined threaded holes with opposite directions; a first knob 9, fixedly connected to one end of the bidirectional screw 7 and extending to the outside of the support frame 2; and a guide rod 12, arranged parallel and symmetrically to the bidirectional screw 7, with both ends fixed to the inner sidewalls of the support frame 2. Each movable rod 8 is also provided with a smooth hole or sliding sleeve, which slides in cooperation with the guide rod 12 to ensure that the movable rod 8 can only move linearly along the guide rod 12 and will not rotate with the bidirectional screw 7.

[0021] The longitudinal adjustment mechanism 6 has the same structure as the lateral adjustment mechanism 5, but the axis of its bidirectional screw 7 is perpendicular to that of the lateral adjustment mechanism 5. It also includes the bidirectional screw 7, two moving rods 8, a first knob 9, and a guide rod 12.

[0022] On the upper surface of each movable rod 8, a guide groove 10 is provided along its length.

[0023] At the bottom end of each recessed block 4, a guide block 11 is vertically fixed. The shape of the guide block 11 matches the guide groove 10, allowing it to be embedded and slide freely. The key connection is that the guide blocks 11 under the left and right feet 3 on the front side of the set-top box body 1 are respectively embedded in the guide groove 10 of the front moving rod 8 in the horizontal adjustment mechanism 5 and the guide groove 10 of the left (or right) moving rod 8 in the vertical adjustment mechanism 6. The guide blocks 11 under the left and right feet 3 on the rear side of the set-top box body 1 are also embedded in the corresponding upper and lower guide grooves 10 in the same staggered manner. This allows the horizontal and vertical degrees of freedom of each guide block 11 to be constrained by a horizontal moving rod 8 and a vertical moving rod 8, respectively.

[0024] To prevent the guide blocks 11 from dislodging from the guide groove 10 of the longitudinal adjustment mechanism 6 located below, a limiting block 13 is also fixedly provided at the bottom end of each guide block 11. The size of the limiting block 13 is larger than the width of the groove 10, so that it is stuck below the guide groove 10.

[0025] How to use: When it is necessary to adjust the front-to-back position of the set-top box body 1 on the support frame 2, rotating the first knob 9 of the longitudinal adjustment mechanism 6 causes its bidirectional screw 7 to rotate, driving the two moving rods 8 to move in opposite directions or back-to-back. This, in turn, drives all the recessed blocks 4 and the set-top box body 1 to move synchronously back and forth via the guide block 11. Similarly, rotating the first knob 9 of the lateral adjustment mechanism 5 adjusts the left-to-right position of the set-top box. Once adjusted to the correct position, the set-top box body 1 is firmly fixed in the target position and cannot be displaced by external force.

[0026] At the bottom end of the support frame 2 near the interface (usually the rear side) of the set-top box body 1, a support plate 16 is movably connected via two lugs 14 fixed to the support frame 2 and a shaft 15 passing through it. The support plate 16 may be made of metal plate.

[0027] The support plate 16 is threaded with four screws 17 arranged in a matrix near the inner side of the support frame 2 (i.e., the side facing the set-top box). Each screw 17 has a second knob 18 fixed to its inner end and extends out of the support plate 16 from its outer end. A rubber sleeve 19 is fitted on the extended section to increase friction and prevent scratching the wall or TV cabinet surface.

[0028] To improve the stability of the support plate 16 in a vertical position, a slot 20 is provided at the bottom end of the support frame 2. Vertical straight slots 21 are provided on both sides of the support plate 16 near its top, through which the shaft 15 passes. This design allows the support plate 16 to not only rotate around the shaft 15 but also move slightly up and down along the straight slots 21.

[0029] The usage status of support plate 16: Horizontal placement: Rotate the support plate 16 upwards until it is flush with the bottom surface of the support frame 2, forming a stable base for placement on the TV cabinet. At this time, the magnets 22 located at the bottom of the support frame 2 and the bottom of the support plate 16 attract each other, preventing the support plate 16 from sagging accidentally.

[0030] Vertical Suspension: When placing the device in a narrow space between the TV and the wall, or on top of an LCD TV, rotate the support plate 16 downwards to a vertical position. Lift the support plate 16 upwards again and insert its top into the slot 20 to lock it in place. Rotate each of the second knobs 18 to extend the screws 17 outwards until the rubber sleeves 19 are firmly pressed against the wall or the back / top of the TV, using friction and support to secure the entire device firmly.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
