Description

Technical Field

[0001] The utility model relates to the technical field of recording equipment, in particular to a film and television synchronous recording rod with a quick-detachable microphone and a non-shaking head. Background Art

[0002] The rapid development of the film and television industry is inseparable from the continuous updating and advancement of audio and video technology. In particular, the sound engineer needs to overcome difficulties in various complex working environments and hold the recording pole high to stabilize the microphone, so as to make accurate and effective recordings, which plays an indispensable role in completing project tasks.

[0003] However, most of the current docking of microphones and recording poles is done by the recording engineer manually tightening the screws between the microphone handle and the recording pole. In fact, this fixing method is achieved by increasing the friction resistance of the fasteners. Since the angle between the microphone and the recording pole is close to vertical, torque will be generated between the two when the recording pole rotates, which can easily overcome the friction resistance of fasteners such as screws, causing the screws to loosen. In actual on-site work, recording engineers often encounter problems such as loosening of the connecting screws between the recording microphone and the recording pole body, causing the microphone to lose control and shake. In mild cases, the work will be stopped for repairs, and the team will have to start over to re-record. In severe cases, it will lead to work accidents, such as some major events, emergencies, natural disasters and other special scenes that cannot be repeated.

[0004] In addition, the traditional method of installing and connecting the recording microphone is to rotate the recording microphone with one hand and the recording rod with the other hand, which is not only time-consuming and labor-intensive, but also very easy to damage the recording equipment. Although some recording engineers currently use a quick-install and quick-release device to solve this problem, due to the complex structure and high price of the device, it not only increases the overall weight and cost, but also makes the original one screw connection point become two, resulting in an increased risk of the microphone shaking. Utility Model Content

[0036] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6 As shown, an embodiment of the utility model provides a film and television synchronous recording rod with a quick-detachable microphone without shaking the head, including a rod body 12, one end of the rod body 12 is connected to a handle 2 through a connecting assembly, and the handle 2 is used to fix the microphone 1; the connecting assembly includes a metal connector 5, one end of the metal connector 5 is inserted in the handle 2, and the other end is provided with a cross spline 7; one end of the rod body 12 is provided with a connecting part for connecting with the metal connector 5, and the connecting part is provided with a cross spline groove 11 adapted to the cross spline 7 to form an axial key and groove plug-in mode, thereby preventing the handle 2 and the rod body 12 from rotating relative to each other.

[0038] The connection assembly also includes a handwheel 4 sleeved on the outer periphery of the metal connector 5, the inner wall of the handwheel 4 is provided with an internal thread, and the cross spline 7 and the outer wall of the connection part are provided with an external thread 8 adapted to the internal thread of the handwheel 4. After the cross spline 7 of the metal connector 5 and the cross spline groove 11 of the connection part are plugged in, the handwheel 4 is screwed on the outer periphery so that the cross spline 7 and the cross spline groove 11 are axially fixed, and the handle 2 and the rod body 12 can be fixedly connected.

[0039] like Figure 2 As shown, a protrusion is arranged on the outer wall of the metal connector 5, and a groove matching with the protrusion of the metal connector 5 is opened on the inner wall of the hand wheel 4, and the groove of the hand wheel 4 and the protrusion of the metal connector 5 are clearance-matched.

[0040] like Figure 3 As shown, the handwheel 4 includes a handwheel base 6 and a handwheel upper cover 10 that are interlocked, and the handwheel base 6 and the handwheel upper cover 10 are detachably connected by screws 9. The internal thread of the handwheel 4 is arranged on the handwheel base 6 and is located on a side away from the handwheel upper cover 10. The groove of the handwheel 4 is also arranged on the handwheel base 6 and is located on a side close to the handwheel upper cover 10. The inner diameter of the handwheel upper cover 10 is smaller than the diameter of the groove. Therefore, the handwheel upper cover 10 cooperates with the groove, so that the handwheel 4 can be fixed relative to the axial direction of the metal connector 5, preventing the handwheel 4 from loosening and falling off, and further improving the stability of the connection between the handle and the rod body.

[0041] In this embodiment, knurling is provided on the outer wall of one end of the metal connector 5 inserted in the handle 2 to increase the friction between the metal connector 5 and the handle 2, so that the metal connector 5 can be more firmly fixed in the handle.

[0042] like Figure 1 and Figure 2 As shown, the handle 2 is provided with a built-in wire groove 3 for storing wires.

[0043] like Figure 4 As shown, the handwheel 4 is hexagonal in shape and made of bronze. The handwheel base 6 and the handwheel upper cover 10 are connected by six screws 9 .

[0044] In this embodiment, the cross spline 7 is made of steel, the nominal diameter of the cross spline 7 and the external thread 8 of the connecting portion is 10 mm, which has good compatibility with the conventional British 3 / 8 recording rod, and the key thickness of the cross spline 7 is 3 mm. The length of the rod body 12 is 2.5 m.

[0045] In the above scheme, the film and television synchronous recording rod adopts an axial key and groove plug-in method to connect the handle and the rod body, thereby avoiding relative rotation of the handle and the rod body. By screwing the hand wheel on the outer periphery of the spline and the connecting part, relative displacement of the handle and the rod body is avoided, so that the connection between the handle and the rod body is stable and reliable, and the structure is simple, the operation is convenient, and the effect of quick installation and quick removal can be achieved.

[0046] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
