It can convert compressed digital signals into television content and display them on the television. The signals can come from cable, satellite antenna, broadband network and terrestrial broadcasting.

[0003] An existing patent (authorization announcement number: CN 214381218 U) discloses a DTMB high-definition digital satellite set-top box with WIFI function. The set-top box body is provided with a protective cover, a first protective pad and a second protective pad on the outside of the set-top box body. The three are all made of rubber material and have good elasticity. The surface of the set-top box body can be protected to prevent the set-top box body from being damaged after accidentally falling, affecting the use, and also causing certain economic losses.

[0004] However, the above technical solution still has certain defects. The protective cover can only protect the set-top box when it falls, and cannot prevent the set-top box from falling from the root. When the set-top box is accidentally moved by external force, the data cable connected to the TV will loosen, thereby affecting its normal work. Therefore, a DTMB high-definition digital satellite set-top box with WIFI function is proposed. Utility Model Content

[0024] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A DTMB high-definition digital satellite set-top box with WIFI function, such as Figures 1 to 6 As shown, it includes a set-top box 100, and both left and right ends of the set-top box 100 are sleeved with protective frames 110, and positioning plates 121 are fixed to the rear surfaces of the two sets of protective frames 110, and a blocking plate 120 is rotatably arranged between the two sets of positioning plates 121;

[0027] A pair of suction cups 113 are embedded at the bottom end of the protection frame 110, a piston cavity 115 is provided in one end of the protection frame 110 close to the positioning plate 121, a piston 116 is slidably provided in the piston cavity 115, a piston rod 117 is provided on the side of the piston 116 close to the heat dissipation window 112, the end of the piston rod 117 extends into the heat dissipation window 112, base rods 123 extending into the positioning plate 121 are provided at both ends of the blocking plate 120, a blind hole 124 is provided at the contact position between the positioning plate 121 and the base rod 123, and a traction rope 125 connected to the end of the piston rod 117 is fixed to the outer wall of the base rod 123;

[0028] A conduit 114 connected to the piston chamber 115 is transversely disposed in the protection frame 110 , and a branch pipe connected to the suction cup 113 is disposed on the outer wall of the conduit 114 .

[0029] Apply external force to the blocking plate 120 to rotate it around the transverse axis of the base rod 123 to a horizontal state, and connect the end of the data cable connected to the TV to the set-top box 100. Then remove the external force applied to the blocking plate 120, and the blocking plate 120 will reverse and return to the upright state and contact one end of the data cable, so that the data cable will not be easily separated from the set-top box 100, effectively avoiding the situation that the set-top box 100 cannot work normally due to external force;

[0030] When the blocking plate 120 rotates from a horizontal state to an upright state, the base rods 123 at both ends thereof rotate accordingly and reel in the traction rope 125, which drags the piston rod 117 and the piston 116 to move, so that the piston chamber 115 is in a negative pressure state, and the suction cup 113 is also in a negative pressure state under the action of the catheter 114, thereby fixing the protection frame 110 and the set-top box 100 on the surface of a desktop or other supporting platform, effectively preventing the set-top box 100 from moving and falling, and further improving the protection effect of the set-top box 100.

[0031] Please refer to Figure 5 and Figure 6 A channel connected to the blind hole 124 is opened in the positioning plate 121 at the contact position with the piston rod 117. The outer wall of the piston rod 117 is located in the conduit 114 and a spring is provided. The two ends of the spring are fixed to the piston 116 and the inner wall of the piston chamber 115. The outer wall of the base rod 123 is located on one side of the traction rope 125 and a torsion spring is provided.

[0032] The setting of the channel facilitates the entry and exit of the piston rod 117 and the movement of the traction rope 125. At the same time, the spring is used to restore the piston rod 117 after movement, so that the pressure in the adsorption returns to normal, and the torsion spring generates an external force on the base rod 123 to ensure that the blocking plate 120 is in an upright state without being subjected to external force.

[0033] Please refer to Figure 2 and Figure 4 A notch 122 is provided at a position corresponding to the joint provided on the rear surface of the set-top box 100 and at the top of the blocking plate 120 , and the number of the notches 122 corresponds to the number of the joints.

[0034] The opening 122 facilitates the insertion of the data cable into the connector at the rear of the set-top box 100 , and can squeeze the end of the data cable to be tightly connected to the set-top box 100 .

[0035] Please refer to Figure 1 The two sets of protection frames 110 are made of rubber material, and elastic rubber strips 111 are connected between the two sets of protection frames 110 and on the upper and lower surfaces of the set-top box 100.

[0036] The protective frame 110 made of rubber material is used to achieve elastic protection to prevent the set-top box 100 from being damaged by rigid contact when it falls on the ground. At the same time, the elastic rubber strip 111 can be stretched and lengthened when an external force is applied, making the disassembly and assembly of the two sets of protective frames 110 more convenient.

[0037] Please refer to Figure 1 The front cross-sectional view of the protection frame 110 is U-shaped, and a soft pad is pasted at the contact position between the inner side of the protection frame 110 and the set-top box 100.

[0038] The U-shaped protection frame 110 can increase the contact area with the set-top box 100 so that it can be stably placed at both ends of the set-top box 100, and the contact surface will not squeeze and damage the set-top box 100 due to the soft pad.

[0039] Please refer to Figure 1 A penetrating heat dissipation window 112 is provided on the outer wall of the protection frame 110 , and heat dissipation ports are provided at positions corresponding to the heat dissipation window 112 on the left and right outer walls of the set-top box 100 .

[0040] The heat dissipation window 112 is used to reduce the contact area with the set-top box 100 and ensure that the set-top box 100 can dissipate heat normally.

[0041] When in use, an external force is applied to the blocking plate 120 to rotate it around the transverse axis of the base rod 123 to a horizontal state, and the end of the data cable connected to the TV is connected to the set-top box 100, and then the external force applied to the blocking plate 120 is removed, and the blocking plate 120 is reversed and restored to an upright state, and contacts one end of the data cable, so that the data cable will not be easily separated from the set-top box 100, effectively preventing the set-top box 100 from not working properly due to external force;

[0042] When the blocking plate 120 rotates from a horizontal state to an upright state, the base rods 123 at both ends thereof rotate accordingly and reel in the traction rope 125, which drags the piston rod 117 and the piston 116 to move, so that the piston chamber 115 is in a negative pressure state, and the suction cup 113 is also in a negative pressure state under the action of the catheter 114, thereby fixing the protective frame 110 and the set-top box 100 on the surface of a desktop or other supporting platform, effectively preventing the set-top box 100 from moving and falling, and further improving the protection effect of the set-top box 100. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0043] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
