DETAILED DESCRIPTION

[0020] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a radio and television wireless data transmission box, comprising a box body 1, a fixing frame 2 fixedly connected to both sides of the box body 1, positioning holes 3 equidistantly opened on each fixing frame 2 along the height direction and a mounting plate 4 fixedly mounted on the fixing frame 2, and a positioning component 5 is installed at the connection between the mounting plate 4 and the fixing frame 2.

[0022] The positioning assembly 5 includes an insertion rod 51 fixedly connected to the inside of the mounting plate 4, a sliding block 52 is slidably connected inside the insertion rod 51, and the cross section of the sliding block 52 is square. One end of the sliding block 52 is fixedly connected to a pressure rod 521, and the other end is provided with a connecting portion, and the cross section of the connecting portion is also square. The outer sleeve of the connecting portion is provided with a first spring 53, and the two ends of the first spring 53 are respectively supported on the sliding block 52 and the insertion rod 51, and push the sliding block 52 to move. Concave springs are provided on both sides of the end of the insertion rod 51 away from the pressure rod 521. The mounting parts are provided with a rotating plate 56 in each mounting part, and the rotating plate 56 is embedded in the corresponding mounting part. One end of the rotating plate 56 close to the pressure rod 521 is rotatably connected to the insertion rod 51, and two connecting ropes 54 are fixedly connected on both sides of the end of the connecting part. One end of each connecting rope 54 away from the sliding block 52 is fixedly connected to the rotating plate 56 on the corresponding side. The first spring 53 pushes the sliding block 52 to reset, and each rotating plate 56 is rotated and its free end is extended, thereby achieving the clamping of the fixed frame 2 and the mounting plate 4.

[0023] Fixed pulleys 55 are rotatably connected to both sides of the insertion rod 51, and the connecting rope 54 passes around the fixed pulley 55 on the corresponding side and is connected to the rotating plate 56 on the corresponding side, so that when the sliding block 52 is reset, it can drive the rotating plate 56 to move and make its free end extend out of the insertion rod 51.

[0024] A torsion spring is provided between each rotating plate 56 and the insertion rod 51, so that the rotating plate 56 has a tendency to retract into the mounting portion, and when the pressure rod 521 is pressed, the torsion spring moves the rotating plate 56 and makes it completely retract into the mounting portion. When the pressure rod 521 is released, the first spring 53 pushes the sliding block 52 to move and overcomes the elastic force of the torsion spring, so that the free end of the rotating plate 56 extends out of the mounting portion.

[0025] Furthermore, the insertion rod 51 is provided in a split form to facilitate the installation of the sliding block 52 and the fixed pulley 55 .

[0026] The mounting plate 4 is slidably connected with a cross bar 57 inside. A pressure block 513 and a limit block 59 are slidably installed inside the mounting plate 4. The limit block 59 is arranged on the side of the pressure block 513 close to the fixing frame 2. The cross bar 57 is arranged between the limit block 59 and the insertion rod 51. One end of the cross bar 57 is fixedly connected with the limit block 59, and the other end slides into the insertion rod 51 and is fixedly connected with the positioning block 58 inside the insertion rod 51. The positioning block 58 is slidably arranged inside the insertion rod 51. A transverse limit rod 511 is arranged inside the mounting plate 4. The transverse limit rod 511 is slidably connected with the limit block 59. A second spring 512 is arranged on the outer sleeve of the transverse limit rod 511. The second spring 512 pushes the limit block 59 to move in the direction close to the insertion rod 51.

[0027] A pressure plate 514 is fixedly connected to one side of the pressure block 513 close to the limit block 59, and a limit groove 510 is provided on the side of the limit block 59 close to the pressure block 513. The limit groove 510 is trapezoidal, and both sides thereof are gradually inclined inward in the direction away from the pressure block 513. The end face of the pressure plate 514 is arc-shaped, and the end face of the pressure plate 514 abuts against the inside of the limit groove 510. The end face of the pressure plate 514 abuts against the side of the limit groove 510, which can drive the limit block 59 to slide in the direction away from the insertion rod 51.

[0028] A limiting ring 516 is fixedly connected to one side of the pressing block 513 close to the insertion rod 51, and a longitudinal limiting rod 515 is fixedly installed in the mounting plate 4. The limiting ring 516 can be slidably sleeved on the outside of the longitudinal limiting rod 515. A third spring 517 is arranged on the outer surface of the longitudinal limiting rod 515. The third spring 517 pushes the pressing block 513 to move in a direction away from the limiting block 59 to release the push on the limiting block 59.

[0029] By setting the positioning component 5, after the insertion rod 51 is inserted into the positioning hole 3, the elasticity of the first spring 53 can drive the sliding block 52 to slide and drive the rotating plate 56 to rotate, so that the surface of the rotating plate 56 abuts against the surface of the fixing frame 2, thereby realizing the rapid assembly between the mounting plate 4 and the fixing frame 2. By pressing the pressing block 513 and then applying a force to the mounting plate 4 away from the fixing frame 2, the rotating plate 56 can be driven to rotate and detach from the inside of the fixing frame 2, thereby realizing the rapid removal of the mounting plate 4, making the operation simple and intuitive, and the user can easily complete the assembly and disassembly without the need for auxiliary tools, thereby saving time and improving work efficiency.

[0030] The outer surface of the insertion rod 51 is inserted into the interior of the positioning hole 3, and the surface of the rotating plate 56 abuts against the surface of the fixing frame 2. By the abutment of the rotating plate 56 against the fixing frame 2, the surface of the mounting plate 4 can abut against the surface of the fixing frame 2.

[0031] The surface of the positioning block 58 close to the insertion rod 51 is arc-shaped, and a slot is provided on the surface of the sliding block 52 close to the positioning block 58. The surface of the positioning block 58 is snapped into the slot. By setting the snap-fit ​​structure between the positioning block 58 and the sliding block 52, when the surface of the rotating plate 56 abuts against the surface of the fixing frame 2, the sliding position of the sliding block 52 can be positioned, and the rotating angle of the rotating plate 56 can be positioned, thereby improving the stability of the mounting plate 4 and the fixing frame 2 after assembly.

[0032] The limit block 59 is slidably connected to the inside of the mounting plate 4 via a transverse limit rod 511, and the surface of the second spring 512 abuts against the surface of the limit block 59. Due to the elasticity of the second spring 512, the limit block 59 normally slides toward the direction close to the insertion rod 51, so that the positioning block 58 is automatically engaged with the inside of the slot.

[0033] The limiting ring 516 is slidably connected to the inside of the mounting plate 4 via the longitudinal limiting rod 515, and the surface of the third spring 517 abuts against the surface of the limiting ring 516. Due to the elasticity of the third spring 517, the limiting ring 516 slides in a direction away from the limiting block 59 under normal conditions.

[0034] When fixing the mounting plate 4, the pressure rod 521 is first pressed to make the sliding block 52 slide in the direction close to the rotating plate 56, and then the rotating plate 56 is rotated to the inside of the insertion rod 51. After the insertion rod 51 is inserted into the positioning hole 3, the pressure on the pressure rod 521 is stopped, and the sliding block 52 is driven to slide quickly in the opposite direction through the elasticity of the first spring 53, and the rotating plate 56 is driven to rotate through the traction of the connecting rope 54, so that the surface of the rotating plate 56 is against the surface of the fixing frame 2. When the surface of the positioning block 58 is engaged with the inside of the side groove of the sliding block 52, the sliding block 52 cannot slide, and the mounting plate 4 is fixed to the surface of the fixing frame 2. When the mounting plate 4 needs to be disassembled, When removing, by pressing the pressure block 513, the pressure block 513 drives the pressure plate 514 to slide downward, and through the abutment between the pressure plate 514 and the inner wall of the limiting groove 510, drives the limiting block 59 to slide to the left. At this time, the limiting block 59 drives the positioning block 58 to slide away from the sliding block 52 through the cross bar 57. The positioning block 58 is separated from the slot. At this time, the sliding block 52 can slide freely, and then a force is applied to the mounting plate 4 away from the fixing frame 2, which can drive the rotating plate 56 to rotate and detach from the inside of the fixing frame 2, thereby realizing the rapid removal of the mounting plate 4, making the operation simple and intuitive. The user can easily complete the assembly and disassembly without the need for auxiliary tools, saving time and improving work efficiency.
