Description

Technical Field

[0001] The utility model relates to the technical field of microphone equipment, in particular to a lifting and resetting device for a special gooseneck microphone. Background Art

[0002] Since the current special gooseneck microphones have unusual stems with large microphone heads, easy scratches, and many stem sections, in actual use, fixed installation is generally preferred, and this kind of stem with complicated lifting and lowering is deliberately avoided. Because during the lifting and lowering process, the stem is often not straight, and the stem head will rub against the panel and damage the stem. The stem with a sponge protective cover will squeeze the sponge protective cover off. During use, people often have to take off or put on the sponge protective cover in advance, or straighten the stem in advance before lifting and lowering. This is not only inconvenient to use, but also adds unnecessary trouble. For a stem with many bends, the stem will be inverted and shortened due to the bending of the stem, which will cause the stem to rub against the panel and damage the stem, and it is more likely to detach the microphone protection device. The next time the stem is lifted and lowered, because the stem is not within the set range, there is no effective protection for the stem, which will directly damage the stem, causing unnecessary economic losses and affecting the service life.

[0033] A wheat protection component 4 is added during the lifting process. The wheat protection component 4 and the lifting drive component 3 work separately and then cooperate with each other. When rising, the wheat straw 53 can move within the set range, and the wheat straw 53 can be freely bent by hand to the ideal position. The wheat straw 53 with sponge does not need to be prepared in advance before use. During the descent, the wheat straightening block 42 automatically straightens the wheat straw 53 so that the wheat straw 53 can be moved to the ideal position of the wheat straw 53 according to the set requirements. The wheat straightening block 42 can prevent the wheat straw 53 from being worn against the panel 21, and the sponge cover does not need to be removed in advance. The wheat straw 53 with multiple bends can also straighten the wheat straw 53 and place the wheat straw 53 in the predetermined position without affecting subsequent operations, and ensure that there is no need to worry about damaging the wheat straw 53 when using it, thus satisfying the customer's use experience.

[0034] In this embodiment, please refer to Figure 1 , Figure 2, the surrounding sides of the support frame 2 are all provided with cover plates. A lifting groove 211 is provided above the support frame 2. The lifting groove 211 is used for the up and down lifting movement of the wheat stem 53. The two sides of the lifting groove 211 are respectively provided with a speaking button 23, a microphone changing button 24 and a lifting switch 25.

Pressing the lifting switch 25 allows the wheat stem 53 to be raised from the support frame 2 to the speaking position or to be lowered and retracted into the support frame 2.

[0035] In this embodiment, please refer to Figure 3 , Figure 4 The wheat-following block 42 includes a mounting portion 421, a wheat-following portion 422 and a sleeve portion 423 which are coaxially arranged. The lower end of the mounting portion 421 is screwed to the fixing plate 44, the upper end of the mounting portion 421 is provided with an external thread, the inner side wall of the lower end of the sleeve portion 423 is provided with an internal thread, and the mounting portion 421 is threadedly connected to the sleeve portion 423. The wheat-following portion 422 is arranged in the sleeve portion 423, the lower end of the wheat-following portion 422 is arranged on the upper end surface of the mounting portion 421, the upper end of the wheat-following portion 422 is abutted against the upper end of the sleeve portion 423 to fix the wheat-following portion 422 on the mounting portion 421, and the efficiency of installing and removing the wheat straw 53 can be improved.

[0036] The inner wall of the microphone slot 43 is protruded toward the center of the slot, and the slot width of the side of the microphone slot 43 facing the microphone head 54 of the microphone 5 is the largest, which improves the efficiency of the microphone and is beneficial to protecting the microphone stem 53.

[0037] Please refer to Figure 2 , Figure 3 The wheat protection assembly 4 also includes a pusher 45 for providing an upward supporting force for the fixed plate 44. One end of the pusher 45 is connected to the fixed plate 44, and the other end of the pusher 45 is fixed to the support frame 2, which improves the stability of the fixed plate 44, thereby improving the efficiency and quality of wheat straightening, and further straightening the wheat straw 53. When the wheat straw 53 is straightened, the wheat straw 53 has a downward friction resistance to the wheat straightening part 422, which drives the fixed plate 44 to slide down along the slide rail on the support frame 2. The pusher 45 can provide an upward supporting force for the fixed plate 44 to overcome the resistance of wheat straightening, so as to make the fixed plate 44 more stable and improve the efficiency and quality of wheat straightening.

[0038] The push member 45 is configured as a gas push rod, a tension spring or a constant force spring structure to save costs.

[0039] In this embodiment, please refer to Figure 2 , Figure 5, a parallel lifting rail 26 and a rack 27 are provided on one side of the support frame 2. The lifting drive assembly 3 includes a motor 31, a fixed seat 32 and a gear 33. The motor 31 is fixed to one side of the fixed seat 32, and the output shaft of the motor 31 passes through the fixed seat 32 and is connected to the gear 33, and the gear 33 is meshed and connected with the rack 27. The gear 33 is located between the rack 27 and the lifting rail 26. The side of the fixed seat 32 facing away from the motor 31 is slidably connected to the lifting rail 26. The upper end of the fixed seat 32 is fixedly connected to the mounting seat 41. The structure is compact, which reduces the occupied space and can also improve the stability of the lifting movement.

[0040] A toggle block 46 is provided on the side of the mounting seat 41 facing away from the motor 31, and a slot is provided on the side of the toggle block 46 away from the mounting seat 41. A traction bar 47 is also provided below the fixed plate 44, and the traction bar 47 is sleeved in the slot. A stopper 48 is provided at the lower end of the traction bar 47, and the stopper 48 is connected with the toggle block 46 to drive the fixed plate 44 and the mounting seat 41 to descend synchronously. When the descent begins, the height difference between the toggle block 46 and the stopper 48 is equal to the length of the wheat straw 53. When the microphone 54 is located in the wheat slot 43, the toggle block 46 is connected with the stopper 48 to drive the microphone 54 into the support frame 2. In addition, the stopper 48 can also prevent the wheat straw 53 from being stretched excessively and affecting the service life of the wheat straw 53.

[0041] The fixing seat 32, the mounting seat 41 and the toggle block 46 are integrally formed to improve the efficiency of installation and the stability of the structure, and to improve the accuracy of distance control.

[0042] Please refer to Figure 1 , Figure 3 The upper end of the support frame 2 is provided with a flap 28 and a torsion spring 29, one end of the torsion spring 29 is connected to the support frame 2, and the other end of the torsion spring 29 abuts against the flap 28, so that the flap 28 can be automatically turned over. The flap 28 is arranged below the lifting slot 211, and a steel wire 34 is arranged below the flap 28, and the steel wire 34 is arranged through the card slot, and a steel wire 34 buckle is arranged at the lower end of the steel wire 34. When the flap 28 is horizontally closed, the toggle block 46 abuts against the steel wire 34 buckle. The position of the steel wire 34 buckle can be adaptively adjusted according to the length of the straw 53.

[0043] The other side of the support frame 2 is provided with a first photoelectric switch 36 and a second photoelectric switch 37 in sequence, and the first photoelectric switch 36 is provided corresponding to the fixed plate 44 to stop the fixed plate 44 from rising. The second photoelectric switch 37 is provided corresponding to the fixed plate 44 to stop the fixed plate 44 from falling, thereby improving the control accuracy.

[0044] Please refer to Figure 4, the wheat straw 53 is slidably arranged on the wheat seat 51 through the wheat core 52. When the mounting seat 41 rises to the set point and stops, the fixed plate 44 drives the wheat straw 53 and the wheat core 52 and the wheat block 42 connected thereto to continue to rise under the action of the pushing member 45, until the fixed plate 44 triggers the first photoelectric switch 36 and stops rising. At this time, the upper surface of the wheat block 42 is flush with the panel 21. When the wheat straw 53 needs to be replaced, the wheat change button 24 is pressed, and the fixed plate 44 drives the wheat block 42 and the fixed plate 44 to rise under the action of the pushing member 45, and the wheat block 42 is located above the panel 21, the wheat block 42 is disassembled, and the wheat straw 53 is taken out for replacement.

[0045] The working principle is explained in detail below.

[0046] Press the lifting switch 25, and during the rising process of the wheat straw 53, the motor 31 is used to drive the wheat straw 53 to rise. At the same time, the toggle block 46 is separated from the steel wire 34 buckle, and the flap 28 realizes the opening function due to its own torsion spring 29. Leave space for the wheat straw 53 and the wheat protection component 4 to rise. The wheat protection component 4 moves with the wheat straw 53, and the relative position between the microphone head 54 and the wheat seat 51 is ensured to remain unchanged by following the wheat straw 53, protecting the microphone head 54 to rise within the set trajectory, and when the upper surface of the wheat block 42 is flush with the panel 21 on the upper surface of the support frame 2, the panel 21 is used to block the fixed plate 44, so that the fixed plate 44 stops. Then the push member 45 is used to provide support force, which is currently achieved by using a gas push rod, mainly for smooth movement during lifting. The wheat straw 53 will not stop here, but will be separated from the mounting seat 41, and the wheat straw 53 will continue to rise through the fixed plate 44 until the first photoelectric switch 36 is triggered and the rise stops. After the wheat straw 53 is raised, the wheat straw 53 is manually bent to the desired ideal speaking position.

[0047] When the meeting is over, press the lifting switch 25, the motor 31 drives the fixed seat 32 to descend, and utilizes the microphone block 42 (the inner core of the microphone part 422 is a plastic part, and the curved surface inside is utilized to automatically straighten the wheat straw 53 when it descends. This can protect the surface of the wheat straw 53 from wear and tear on the panel 21, and can also protect the head of the wheat straw 53 in the set position). Combined with the pusher 45, ensure that the fixed plate 44 is flush with the panel 21, and further ensure that the friction between the wheat straw 53 and the microphone block 42 causes the fixed plate 44 to sink and cause damage to the wheat straw 53, thereby truly protecting the wheat. When the wheat straw 53 descends and automatically straightens the wheat straw 53, at the same time, when the wheat straw 53 descends to the point where the microphone head 54 is flush with the upper surface of the microphone block 42, the pusher 45 is utilized to straighten the wheat straw 53. At this time, the motor 31 drives the block 48 at the lower end of the traction bar 47 to descend by using the toggle block 46, and the wheat straw 53 and the wheat follower block 42 are separated from the panel 21 to achieve synchronous descent. When descending to a certain extent, the toggle block 46 drives the steel wire 34 buckle, and the connected steel wire 34 pulls the flap 28 until it is flush with the panel 21, triggering the second photoelectric switch 37, and the descent is completed. In this way, the wheat straw 53 can be ensured to move within the set trajectory, and the sponge protective cover can also be effectively protected to prevent the risk of falling.

[0048] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
