Description

Technical Field

[0001] This utility model relates to the field of classroom equipment technology, and more specifically to an adjustable handheld microphone holder for classroom use. Background Technology

[0002] During the teaching process, because the classroom space is large and can accommodate more people, students in the back rows may not be able to hear the lecturer. In this case, the lecturer will usually use a microphone to amplify the sound to achieve a good teaching effect.

[0003] The existing microphones require users to hold the microphone base in place, loosen the knob, and then hold the lifting lever to raise or lower the microphone. Once the desired height is reached, the knob must be tightened to secure it. This process is cumbersome, cannot be operated with one hand, affects classroom teaching efficiency, and is not very practical.

[0004] Therefore, there is an urgent need for an adjustable handheld microphone stand for classroom use. Utility Model Content

[0007] An adjustable handheld microphone holder for classroom use includes a slide groove for horizontal mounting on a lectern, with a slider slidably disposed within the slide groove; a base column is connected to the upper end of the slider, and a vertically mounted height adjustment mechanism is connected to the base column; a hinge seat is connected to the top of the height adjustment mechanism, and a damping hinge is connected to the hinge seat; the damping hinge is connected to a telescopic mechanism for adjusting the distance between the microphone and the user, and the telescopic mechanism is connected to a mounting base; the mounting base is connected to a bracket for placing the microphone.

[0008] The technical solution is further optimized. The height adjustment mechanism includes a first sleeve connected to the bottom column, and a vertically arranged adjustment port is opened on the side wall of the first sleeve. A height adjustment rod is sleeved inside the first sleeve, and a first adjustment clip is installed on the height adjustment rod. A plurality of evenly arranged first positioning holes for fixing the first adjustment clip are provided on the side wall of the first sleeve.

[0009] To further optimize the technical solution, the first adjustment card includes a fixed plate located inside the adjustment port and connected to the height adjustment rod, and a fixed seat is provided on the fixed plate; a torsion spring is hinged on the fixed seat, and the other end of the torsion spring is connected to the adjustment plate through the fixed seat; the end of the adjustment plate is provided with a locking block that cooperates with the first positioning hole.

[0010] To further optimize the technical solution, the telescopic mechanism includes a second sleeve connected to a damping hinge, the second sleeve having the same structure as the first sleeve; a telescopic adjustment rod is sleeved inside the second sleeve, and a second adjustment clip with the same structure as the first adjustment clip is provided on the telescopic adjustment rod.

[0011] To further optimize the technical solution, the mounting base is fixedly mounted on the telescopic adjustment rod via a second damping hinge.

[0012] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.

[0013] This utility model provides an adjustable handheld microphone holder for classroom use. A sliding groove allows for changing the holder's position, covering the entire lectern area. A height adjustment mechanism allows for overall height adjustment, a telescopic mechanism allows for adjusting the distance between the microphone and the user, and a hinged base allows for 360° rotation of the microphone within a radius equal to the projection of the damping hinge to the telescopic adjustment rod. Fine adjustments to height and angle are possible by adjusting the mounting base. All adjustments can be made with one hand, without interfering with the user holding textbooks, teaching aids, laser pointers, etc. It boasts advantages such as simple structure, wide adjustment range, ease of use, simple operation, and single-handed operation.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] An adjustable handheld microphone holder for classroom use, combined with Figures 1 to 3As shown, it includes a slide groove 1, a slider 2, a bottom column 3, a first sleeve 4, a first positioning hole 41, an adjustment port 42, a height adjustment rod 5, a first adjustment clip 6, a fixing plate 61, a fixing seat 62, a torsion spring 63, an adjustment plate 64, a clip 65, a hinge seat 7, a damping hinge 8, a second sleeve 9, a second adjustment clip 10, a mounting base 11, a bracket 12, and a telescopic adjustment rod 13.

[0017] The height adjustment mechanism includes a first sleeve 4, a first positioning hole 41, an adjustment port 42, a height adjustment rod 5, a first adjustment clip 6, a fixing plate 61, a fixing seat 62, a torsion spring 63, an adjustment plate 64, and a clip 65.

[0018] The slide 1 can be horizontally installed on the lectern using bolts or similar means. A slider 2 is slidably installed within the slide 1, which can move the microphone holder left and right to expand the microphone's usability. A base post 3 is connected to the upper end of the slider 2, and a vertically installed height adjustment mechanism is connected to the base post 3.

[0019] The height adjustment mechanism includes a first sleeve 4 connected to the base column 3. A vertically arranged adjustment port 42 is provided on the side wall of the first sleeve 4 to provide space for the first adjustment clip 6 to move. A height adjustment rod 5 is fitted inside the first sleeve 4, and the first adjustment clip 6 is mounted on the height adjustment rod 5. Several evenly arranged first positioning holes 41 are provided on the side wall of the first sleeve 4 for fixing the first adjustment clip 6 in the adjusted position. The first adjustment clip 6 includes a fixing plate 61 located inside the adjustment port 42 and connected to the height adjustment rod 5. A fixing seat 62 is provided on the fixing plate 61. A torsion spring 63 is hinged to the fixing seat 62, and the other end of the torsion spring 63 is connected to an adjustment plate 64 through the fixing seat. A locking block 65 is provided at the end of the adjustment plate 64 to cooperate with the first positioning hole 41.

[0020] The top of the height adjustment mechanism is connected to a hinge seat 7 to adjust the angle of the upper part of the microphone holder.

[0021] A damping hinge is connected to the hinge base 7, and the damping hinge 8 is connected to a telescopic mechanism for adjusting the distance between the microphone and the user. The telescopic mechanism includes a second sleeve 9 connected to the damping hinge 8. The second sleeve 9 has the same structure as the first sleeve 4. A telescopic adjustment rod 13 is fitted inside the second sleeve 9. A second adjustment clip 10 is provided on the telescopic adjustment rod 13. The second adjustment clip 10 has the same structure as the first adjustment clip 6, and the principle and method of adjustment are also the same.

[0022] The telescopic mechanism is connected to the mounting base 11, which is connected to a bracket 12 for placing the microphone. The mounting base 11 can be fixedly mounted on the telescopic adjustment rod 13 via a second damping hinge to facilitate adjustment of the microphone angle.

[0023] In practical use, this invention allows for adjustment of the microphone's position by dragging the upper part of the mounting base to move the slider along the slide groove. The length of the slide groove can be selected according to the length of the lectern. Height adjustment is achieved by pressing the first adjustment clip, which moves directly up or down to the desired position after leaving the first positioning hole. Then, the first adjustment clip is moved into the corresponding new first positioning hole for stable positioning. The telescopic mechanism can be adjusted 360° by rotating the hinge base; the adjustment process is the same as height adjustment. Smaller angle and height adjustments can be made directly by adjusting the mounting base. All adjustments can be performed with one hand, without affecting the user's ability to hold teaching materials, teaching aids, laser pointers, etc., making it convenient and simple to use.
