Description

Technical Field

[0001] This utility model belongs to the field of receivers, specifically, it relates to a portable digital satellite receiver. Background Technology

[0002] Color digital satellite receivers are widely used in daily life. Most color digital satellite receivers are connected to a power outlet via a wire to ensure normal use. There are many types of color digital satellite receivers on the market.

[0003] Chinese Patent Publication No. CN221598321U discloses a portable digital satellite receiver, comprising: a main unit, which includes a chassis body and an auxiliary plate fixedly connected to the upper surface of the chassis body; and a portable heat dissipation unit, which includes a sliding plate fixedly connected inside the chassis body and a fixed shaft fixedly connected inside a placement slot. This invention utilizes a lever to drive a pressure plate to rotate on the outer surface of the limiting shaft, thereby allowing the handle inside the placement slot to be lifted. Pulling the handle allows the entire device to be extracted and placed, thus improving space utilization efficiency and making the device easier to carry and handle, enhancing its practicality. Furthermore, a fan draws external air into the chassis body. During installation, rollers can be used to drive the placement plate, allowing the plate to carry internal components into the chassis body. This enables quick removal of the device in case of malfunction, improving maintenance efficiency and reducing resource consumption.

[0004] Existing digital satellite receivers are usually standalone units. Due to their small size, they are typically carried by hand. However, because there is no suitable point of leverage, they are prone to slipping and falling, causing damage to the digital satellite receiver. Therefore, they are inconvenient to carry. Although the above-mentioned application provides an outer casing for the digital satellite receiver to facilitate carrying and moving, the digital satellite receiver is still inside the casing during subsequent use. Heat dissipation requires a fan installed inside the casing, which consumes energy and increases the weight of the digital satellite receiver when carried, making it less convenient.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] Please see Figure 1-5 As shown, this embodiment provides a portable digital satellite receiver, including a housing 1. Rotating shafts 10 are rotatably fitted on opposite sides of the upper part of the housing 1. A left cover 2 and a right cover 3 are fixed to the periphery of the two rotating shafts 10 respectively. Locking handles are installed on the upper part of the left cover 2 and the right cover 3.

[0036] A filter cover 7 is slidably fitted inside the outer casing 1. The receiver body 8 is installed inside the filter cover 7. A cover 9 is rotatably fitted on the top of the filter cover 7. A winding box 16 is installed on the rear side inside the filter cover 7. Two connecting rods 15 are rotatably fitted inside the outer casing 1. A rotating rod 12 is fixed to one end of the connecting rod 15. A belt 11 is wrapped around the circumference of the rotating shaft 10 and the rotating rod 12. A gear 13 is fixed around the circumference of the connecting rod 15. A toothed plate 14 is vertically fixed on the opposite outer side of the filter cover 7. The gear 13 meshes with the toothed plate 14.

[0037] One application of this embodiment is as follows: When using the digital satellite receiver, the locking handle can be opened first, allowing the left cover 2 and right cover 3 to rotate open to both sides. During the opening process, the left cover 2 and right cover 3 will drive the two rotating shafts 10 to rotate. Then, the rotating shafts 10 drive the belt 11 to move, causing the belt 11 to drive the rotating rod 12 and connecting rod 15 to rotate. At this time, the connecting rod 15 synchronously drives the gear 13 to rotate, causing the gear 13 to mesh with the toothed plate 14 and drive the filter cover 7 to move upward. Then, the filter cover 7 drives the receiver body 8 to extend out of the outer shell 1 for use. During use, the filter cover 7 protects the receiver body 8 from the surrounding area, preventing dust from entering, and does not affect the heat dissipation effect. After use, closing the left cover 2 and right cover 3 will synchronously drive the filter cover 7 and receiver body 8 to retract into the outer shell 1 for storage. The locking handle is used to lock the left cover 2 and right cover 3 closed. The user can manually lift the locking handle to carry the digital satellite receiver for movement. It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0038] like Figure 2As shown, the locking handle in this embodiment includes a support rod 4 fixed to the upper side of the left cover 2, an L-shaped rod 5 rotatably fitted to the upper end of the support rod 4, a groove formed on the upper side of the right cover 3, and a locking block 6 elastically slidingly fitted in the groove and engaging with the inner side of one end of the L-shaped rod 5. When the left cover 2 and the right cover 3 are opened, the engagement between the locking block 6 and the inner side of one end of the L-shaped rod 5 is released, and then the L-shaped rod 5 is rotated so that the other end of the L-shaped rod 5 rotatably engages with the upper end of the support rod 4.

[0039] like Figure 2 As shown, in this embodiment, the locking block 6 slides laterally within the groove, and a spring is fixed between one end of the locking block 6 and the inner wall of the groove. A limiting groove is formed on the inner side of one end of the L-shaped rod 5, and the other end of the locking block 6 corresponds to the limiting groove. When the left cover 2 and the right cover 3 are closed and locked, the L-shaped rod 5 is rotated, causing the other end of the L-shaped rod 5 to rotate and engage with the upper end of the support rod 4. Then, the support rod 4 and the L-shaped rod 5 form a U-shaped structure. At this time, one end of the L-shaped rod 5 extends into the groove, and the elastic spring rebounds, causing the locking block 6 to slide within the groove. Then, one end of the locking block 6 extends into the limiting groove on the inner side of one end of the L-shaped rod 5 to create a locking relationship.

[0040] like Figure 5 As shown, a connecting cable 17 is connected to the rear side of the receiver body 8 in this embodiment, and the connecting cable 17 corresponds to the winding box 16. The winding box 16 has the same working principle and operation method as the "charging cable winding box" in the prior art. When the receiver body 8 is not in use, the winding box 16 winds up the connecting cable 17.

[0041] like Figure 5 As shown, in this embodiment, the two connecting rods 15 are located on opposite sides of the filter cover 7, and the gear 13 is located on one side of the rotating rod 12. When the belt 11 drives the rotating rod 12 to rotate, the rotating rod 12 synchronously drives the connecting rod 15 and the gear 13 to rotate, and the connecting rod 15 positions the rotating rod 12.

[0042] like Figure 2-3 As shown, in this embodiment, through grooves are provided in the middle of the upper sides of the outer casing 1 and the middle of the lower sides of the left cover 2 and right cover 3. The belt 11 is rotatably engaged in the through grooves. When the left cover 2 and right cover 3 are opened, the rotating shaft 10 will be driven to rotate, and then the rotating shaft 10 will drive the belt 11 to move in the through grooves.

[0043] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
