DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment, this embodiment provides a wall-mounted course recording device, such as Figure 1 As shown, it includes: a wall seat 1, the wall seat 1 has a longitudinal mounting portion extending longitudinally, the longitudinal mounting portion is provided with a sinking mounting hole, a hole is pre-opened on the wall, the longitudinal mounting portion is placed against the wall, the sinking mounting hole is directly opposite to the wall hole, and an expansion bolt is used to pass through the sinking mounting hole and embed into the wall hole to realize fixed installation of the longitudinal mounting portion.

[0024] At the same time, the wall seat 1 is laterally extended with a rotation support part, the longitudinal mounting part laterally supports the rotation support part, and an oblique support rod is fixed between the bottom end of the side wall of the longitudinal mounting part and the bottom wall of the rotation support part, and the oblique support rod is used to enhance the support stability of the rotation support part. An I-shaped pin 21 is rotatably clamped on the rotation support part, and a crossbeam 2 is fixed to the radial side wall of the I-shaped pin 21. The crossbeam 2 rotates with the I-shaped pin 21 as the rotation center, and the direction of the end of the crossbeam 2 is adjusted, that is, the crossbeam 2 is rotated with the I-shaped pin 21 as the rotation center, and the crossbeam 2 can be rotated to be close to the side wall of the longitudinal mounting part, and can be distributed parallel to the longitudinal mounting part, that is, close to the wall, to reduce the lateral span of the crossbeam 2 when it is away from the wall. The end of the crossbeam 2 away from the I-shaped pin 21 rotates away from the longitudinal mounting part and is flipped and adjusted to the side away from the wall.

[0025] like Figure 1 and Figure 2As shown, the sliding seat 3 is adjustably sleeved on the beam 2. Specifically, the sliding seat 3 is provided with a sleeve hole for slidingly sleeved with the beam 2. The end of the beam 2 away from the I-shaped pin 21 has a shielding portion extending up and down. The sliding seat 3 is sleeved on the outer wall of the beam 2 using the sleeve hole. The top wall inside the sleeve hole is slidably fitted with the upper end surface of the beam 2, and the position of the sliding seat 3 is adjusted by horizontal sliding along the upper end surface of the beam 2. At the same time, a hanging frame 31 is provided at the bottom end of the side walls on both sides of the sliding seat 3, and a plurality of clamping seats 32 are fixed to the side walls on the side away from each other of the two hanging frames 31, and a clamping notch is provided on the upper end surface of the clamping seat 32; it also includes a lifting support plate 33, and two lifting support plates 33 are provided. A hanging plate 36 is fixed between the bottom ends of the two lifting support plates 33, and a camera 4 is installed on the bottom wall of the hanging plate 36. The hanging frame 31, the lifting support plate 33 and the hanging plate 36 form a hanging mechanism for hanging the camera 4 in the air, and a clamping shaft 34 is fixed to the top of the opposite side walls of the two lifting support plates 33, and the clamping shaft 34 matches the clamping notch, so that the camera 4 is hung in the air at a position directly below the sliding seat 3.

[0026] The beam 2 is rotated according to the shooting direction of the camera 4. For example, when the teacher is standing on the podium to teach, the beam 2 is rotated 90 degrees from the position close to the wall so that the beam 2 and the longitudinal mounting part are vertically distributed in the same plane. At this time, the camera 4 can be directed to the podium. At the same time, the position of the sliding seat 3 on the beam 2 is adjusted horizontally along the outer wall of the beam 2 so that the lens of the camera 4 can be aimed at the teacher on the podium to record the teaching content. This solves the problem that the traditional use of a bracket to support the camera 4 affects the movement of people and is easily knocked over and broken by humans.

[0027] In addition, after the shooting is finished, it is only necessary to rotate the beam 2 in the opposite direction around the I-shaped pin 21, and the beam 2 is rotated and reset to be close to the wall, and the camera 4 is adjusted synchronously with the beam 2 through the hoisting mechanism. There is no need to support the camera 4 before shooting, and there is no need to disassemble the camera 4 for storage after the recording is finished, which is convenient for quickly adjusting the position of the camera 4 during teaching.

[0028] In order to prevent the clamping shaft 34 from accidentally disengaging from the clamping notch, a guide rod 35 is rotatably provided at the bottom end of the side wall of the two hanging frames 31 away from each other, and the lifting support plate 33 is provided with a lifting sliding hole slidably sleeved with the radial outer wall of the guide rod 35, such as Figure 1 and Figure 2 As shown, the lifting support plate 33 can swing with the guide rod 35 as the swing center, driving the clamping shaft 34 to follow the swinging lifting support plate 33 to deviate from the vertical direction of the clamping seat 32, and the inner wall of the lifting slide hole and the outer wall of the guide rod 35 slide up and down to adjust, and the clamping shaft 34 follows the lifting support plate 33 to adjust its position synchronously.

[0029] At the same time, in order to prevent the sliding seat 3 from sliding randomly along the outer wall of the beam 2, the position of the camera 4 cannot face the teacher on the podium, resulting in the shooting picture failing to meet the requirements. An inverted T-shaped rod 37 is slidably inserted into the bottom wall of the socket hole. A top plate 38 is fixed to one end of the inverted T-shaped rod 37 located in the socket hole. A rubber cone block 39 is provided on the upper end surface of the top plate 38. The bottom wall of the beam 2 is provided with a plurality of grooves 23 evenly spaced in a straight line structure. The inverted T-shaped rod 37 is sleeved with a spring located between the top plate 38 and the bottom wall of the socket hole. Figure 2 and Figure 3 As shown, the elasticity of the spring is used to adjust the top plate 38 and the inverted T-bar 37 upward synchronously, so that the rubber cone block 39 on the upper end surface of the top plate 38 can be pushed into the groove 23 at the corresponding position, and the friction force generated by the contact between the outer wall of the rubber cone block 39 and the inner wall of the groove 23 is used to make the sliding seat 3 slide freely without external force, resulting in a change in the shooting position of the camera 4, and then the shooting screen cannot fully record the teacher's teaching screen. Of course, when adjusting the position of the sliding seat 3, the lifting mechanism is pushed horizontally to synchronously drive the camera 4 to adjust the position. The rubber cone block 39 has the deformable characteristic. When pushed horizontally, the outer wall of the rubber cone block 39 contacts the inner wall of the groove 23, which will squeeze the outer wall of the rubber cone block 39 and deform it, and then cross the groove 23 and enter the next adjacent groove 23, thereby adjusting the position of the sliding seat 3.

[0030] A T-shaped slide rail is provided at one end of the bottom wall of the cross beam 2 near the I-shaped pin 21, and an I-shaped slide shaft 24 is slidably provided in the T-shaped slide rail. An extension portion is vertically fixed to the bottom end of the radial side wall of the I-shaped slide shaft 24, and the bottom end of the extension portion is connected to a guide wire frame 22 after extending out of the T-shaped slide rail. The space inside the guide wire frame 22 is used for the power line of the camera 4 to pass through. Figure 4 As shown, there are multiple guide wire frames 22, and the power line of the camera 4 is fixed and suspended in the air by using multiple guide wire frames 22, and the power line is fixed to the guide wire frame 22 by using a binding belt, which can prevent the power line from being loosened at a local position and falling seriously, and prevent the power line from being entangled. At the same time, when the sliding seat 3 slides along the outer wall of the beam 2, the position of the camera 4 is adjusted synchronously, and the tension of the power line is adjusted, and the power line drives the guide wire frame 22 to move synchronously, and then drives the I-shaped sliding shaft 24 to slide horizontally along the T-shaped slide rail to cooperate with the movement of the power line.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
