Description
Technical field
The utility model relates to a kind of microphone holder, particularly the microphone holder of a kind of inner tube free damping lifting.
Background technology
at present, microphone holder generally includes the outer tube that is connected on base, be plugged with inner tube in outer tube, microphone is arranged on the top of inner tube, people can regulate for the placing height that can make microphone, thereby but the inner tube of microphone holder is set to free lifting, and the device of realizing this elevating function includes a connector that is arranged on the outer tube top, external screw thread and locking pawl are arranged on the pedestal of connector, pedestal is to there being a sleeve, inner tube is plugged in the pore of outer tube, sleeve locks or decontrols inner tube by the main lifting inclined slide unit on pedestal and secondary lifting inclined slide unit and the pedestal on sleeve.Although this structure can realize the height of inner tube and regulate locking,, in actual use, the user can not the free lifting support, uses inconvenient.
In addition, also have on the market and a kind ofly realize highly regulating and the microphone holder structure of inner tube locking by pull bar, bracer, although when using more for convenience, but, the problem that exists is that parts are very complicated, and not only cost is high, and efficiency of assembling is low and be easy to damage.
Summary of the invention
For addressing the above problem, but the purpose of this utility model is to provide a kind of simple and reasonable, microphone holder of using reliable free lifting.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of microphone holder comprises be used to the outer tube that is connected on base, is plugged with in outer tube for the inner tube that vertically moves that supports microphone, also comprises: damping piece, connector; Described damping piece is threadedly connected to the bottom of described inner tube, and described damping piece contacts and oppress the outer tube wall face with the outer tube wall face; Described connector is connected with the outer tube screw top, and inner tube is passed described connector; Described connector comprises pedestal, shell; The external screw thread that described pedestal is connected with outer tube by the internal thread on pedestal is connected with external pipe thread; The external screw thread that described shell is connected with pedestal by the internal thread on shell is connected with base thread; Also be provided with some promptly ratchets for compressing outer wall of inner tube face on described pedestal.Damping piece forms stiction by compressing outer tube wall face, be used for supporting inner tube, microphone and wiring, perhaps when vertically moving, the relative outer tube of inner tube produces kinetic force of friction, the stiction of damping piece and outer tube wall face is enough to support the weight of inner tube, microphone and wiring, and the size to fit of the kinetic force of friction of damping piece is in the free lifting support simultaneously.Firmly grasping on connecting piece base produces stiction when ratchet is oppressed the outer wall of inner tube face, be used for supporting inner tube, microphone and wiring, perhaps when vertically moving, the relative outer tube of inner tube produces kinetic force of friction on the outer wall of inner tube face, promptly ratchet and the stiction of outer wall of inner tube face are enough to support the weight of inner tube, microphone and wiring, firmly grasp simultaneously the size to fit of kinetic force of friction of ratchet in the free lifting support.
Further, described damping piece is pawl structures, damping piece has some damping ratchets, the outside of damping ratchet is provided with positive slope boss, the maximum gauge in the boss outside, positive slope is greater than the outer tube wall diameter, can utilize the outer tension force of damping ratchet to contact and oppress the outer tube wall face with the outer tube wall face when making damping piece within the outer tube, damping ratchet top outer edge is to be conducive to the incline structure that damping piece enters outer tube.
Further, described damping piece comprises the ratchet strutting piece, and damping piece and Internal Pipe Thread coupling part are tubular structure, and damping piece is threaded with the ratchet strutting piece by internal thread and the external screw thread on the ratchet strutting piece of damping piece; Be provided with the rubber circle between damping ratchet and ratchet strutting piece, be used for resiliency supported damping ratchet; Ratchet strutting piece arranged outside has two annular ridges, is used for locking rubber circle.The ratchet strutting piece can strengthen the compressing power of damping ratchet and outer tube wall face on the one hand, prevents that on the other hand the damping ratchet from producing fatigue of materials and following the string.
Further, described outer casing inner wall is taper.When described shell and pedestal screwed, promptly ratchet tightened up the compressing inner tube, like this can be at damping piece and when promptly the maximum static friction force of ratchet is not enough to support inner tube, strengthen compressing to inner tube by tightening up ratchet promptly.
Further, the interior diameter of described promptly ratchet is less than the outer diameter of inner tube.This structure can make promptly ratchet compressing inner tube.
Further, described connector also comprises locating ring, scratch resistant cushion rubber, retainer ring.Described locating ring is fixed in the outer casing inner wall top, and inner tube is passed locating ring, and the locating ring inwall is provided with annular groove, and described scratch resistant cushion rubber is fixed in annular groove.Locating ring is used for the location inner tube, and the transverse movement that makes inner tube not produce relative outer tube is provided with scratch resistant cushion rubber simultaneously, scratches for preventing that the outer wall of inner tube face is positioned to encircle.
Further, described retainer ring is connected in the outer casing inner wall bottom by the external screw thread on retainer ring and the internal thread on shell and outer casing screw, and inner tube is passed retainer ring.Retainer ring is used for limiting the scope of activities of shell, shell is screwed on pedestal be unlikely to break away from connector when unscrewing.
Preferably, described promptly ratchet and outer wall of inner tube face contact portion are made into shiny surface.This design can prevent being scratched of outer wall of inner tube face.
the beneficial effects of the utility model are: the microphone holder of a kind of inner tube free damping lifting that the utility model adopts, be provided with damping piece and firmly grasp ratchet, contact and oppress the outer tube wall face and firmly grasp ratchet compressing outer wall of inner tube face by damping piece and produce stiction, thereby for inner tube provides support power, the maximum static friction force that damping piece provides is enough to support the weight of inner tube and microphone etc., when damping piece with when promptly the maximum static friction force that provides of ratchet is not enough to support the weight of inner tube, can make promptly ratchet contraction by the shell that screws on connector, promptly thereby ratchet strengthens the compressing to the inner tube outside wall surface, increase maximum static friction force.Support inner tube of the present utility model can free lifting, and free adjustment microphone height is simple and reasonable, easy to use and reliable.
