Description

Technical Field

[0001] The utility model relates to the technical field of speaker connection, and more specifically, to a wall-mounted speaker stand. Background Art

[0002] A speaker is a device that restores an electrical signal into a sound signal, and the restoration authenticity will be an important criterion for evaluating the performance of the speaker. An active speaker is an audio system with a power amplifier (i.e., a power amplifier), which integrates the power amplifier and the speaker sound system, and can be directly paired with general sound sources (such as a walkman, a CD player, a DVD player, a video recorder, etc.) to form a complete audio combination. When the speaker needs to be used at a higher position, it is generally directly elevated through a speaker stand or connected to the outer surface of a wall or a building through a wall-mounted bracket.

[0003] In the existing speaker wall-mounted bracket, a vertical fixed insertion tube is usually provided for mating with an insertion hole preset at the bottom of the speaker. There is no other locking mechanism between the upper end of this fixed insertion tube and the speaker base, or it is fixed by conical fit, that is, the bracket plug and / or the speaker jack is conical. However, since the height of the speaker is relatively high after being installed on the speaker stand, it is easy for the speaker to shake between the speaker and the speaker stand; or when used in a poor outdoor environment, the connection between the speaker and the fixed insertion tube becomes more unstable, and the collision between the speaker jack and the fixed insertion tube under the influence of factors such as wind causes noise, affecting the sound effect. Moreover, in the form of conical surface fit fixation, it is easy to insert too deep, resulting in inconvenient disassembly of the speaker and the fixed insertion tube. Summary of the Utility Model

[0004] To overcome at least one defect in the above prior art, the utility model provides a wall-mounted speaker stand to solve the problems of unstable mating between the speaker and the fixed insertion tube, affecting the sound effect, and inconvenient disassembly in the prior art.

[0005] The utility model provides a wall-mounted speaker stand: including a fixed bracket and a support rod, one end of the support rod is connected to the fixed bracket in a vertically adjustable angle, the other end of the support rod is connected with a support component for inserting and fixing the speaker, the support component includes an insertion tube vertically connected to the support rod, at least one support block capable of expanding and contracting radially is connected to the side wall of the insertion tube, an actuating member capable of moving up and down to drive the support block to expand and contract radially is arranged in the insertion tube, and a driving component for driving the actuating member to move up and down is connected to the lower end of the insertion tube; a telescopic diagonal support component is rotatably connected to one end of the support rod away from the fixed bracket, and the end of the diagonal support component away from the support component is rotatably connected to the fixed bracket.

[0006] Compared with the prior art, the wall-mounted speaker stand of the utility model has the following advantages:

[0007] In the speaker stand structure of the present utility model, it is connected to the outer wall of a building or a bracket through a fixed bracket. A support rod is rotatably connected to the fixed bracket, and a support assembly for inserting a speaker is connected to the support rod. By adjusting the vertical angle of the support rod, the tilt angle of the speaker can be adjusted to meet the sound pointing in different ranges. Additionally, the support assembly in this structure can achieve locking and loosening with the socket of the speaker base. Specifically, through the cooperation of the insertion tube and the insertion hole at the bottom of the speaker, after the insertion is completed, by operating the drive assembly to drive the actuator to move upward, under the action of the actuator, the support block can expand radially outward until it is tightly limited against the inner wall of the insertion hole at the bottom of the speaker, realizing the insertion and locking function with the speaker base, thereby ensuring a stable connection between the speaker and the connection body, and preventing noise caused by factors such as wind blowing and shaking, without affecting the sound quality of the speaker. When disassembling, it is also only necessary to operate the drive assembly to drive the actuator to move downward and reset, so that the support block no longer abuts against the inner wall of the insertion hole, and the insertion tube can be easily pulled out from the socket, which is very convenient.

[0008] As an improvement, at least one support member capable of deforming radially along the insertion tube is provided inside the insertion tube. Through holes are provided on the side wall of the insertion tube, and a support block capable of extending out of the through holes is provided on the outer wall of the support member. When the drive assembly drives the actuator to move upward, the actuator is used to drive the support member to deform radially outward until the support block extends out of the through holes. In the above improved structure, by driving the support member to deform radially outward by the upward movement of the actuator, the outer end of the support block passes through the through hole and abuts against the inner wall of the preset insertion hole at the bottom of the speaker. When it is necessary to disassemble the speaker, it is only necessary to drive the actuator to move downward in the reverse direction, which is very convenient.

[0009] Further improved, the actuator is a cylindrical top column, and a tapered portion with a diameter gradually decreasing from top to bottom is provided at the upper end of the top column. The inner side surface of the support member is a tapered surface matching the tapered portion. In the above improved structure, the setting of the tapered portion and the tapered surface enables the top column to better drive the support member to have a radial offset when moving upward, so that the support block can pass through the through hole and tightly limit the inner wall of the socket of the speaker base.

[0010] Further improved, a blanking cover is connected to the top of the insertion tube. A limiting tube inserted and matched with the insertion tube is provided at the lower end of the blanking cover. A limiting card slot is provided on the outer peripheral wall of the limiting tube, and the upper end of the support member is fitted in the limiting card slot. A movable gap for the radial deformation of the support member is left between the outer wall of the lower end of the support member and the inner wall of the insertion tube. In the above improved structure, the pre-positioning of the support member is realized through the blanking cover. During installation, it is only necessary to insert the blanking cover and the top of the insertion tube to make the support block at the lower end of the support member opposite to the position of the through hole, which is very convenient.

[0011] Further improved, there are three supporting members circumferentially distributed along the circumferential direction of the insertion tube, and there are three limiting card slots circumferentially arranged on the outer peripheral wall of the limiting tube; and the limiting card slot is a T-shaped slot, and a T-shaped clamping block matching the T-shaped slot is arranged at the upper end of the supporting member. In the above improved structure, arranging three supporting members circumferentially can better ensure its locking fit with the jack of the speaker base, and the T-shaped slot structure facilitates the quick installation of the supporting member and the blanking cover.

[0012] Furthermore, the driving assembly includes an adjusting screw and a driving nut. The driving nut is connected to the bottom of the inner cavity of the insertion tube. The adjusting screw is fitted in the driving nut, and the upper end of the adjusting screw is connected to the actuating member, and the lower end of the adjusting screw is exposed outside the lower end of the support rod. In the above structure, when the adjusting screw is rotated, the actuating member can move up and down under the action of the spiral mating surface, so as to drive the radial movement of the supporting block, and finally realize the locking and loosening of the insertion hole at the bottom of the speaker. The structure is simple and the operation is convenient.

[0013] Further improved, both the fixed bracket and the support rod are hollow square tubes, and the fixed bracket is arranged vertically. First mounting holes and second mounting holes are arranged up and down on the outer wall of the fixed bracket. One end of the support rod is rotatably connected in the first mounting hole, and one end of the diagonal support assembly is rotatably connected in the second mounting hole; a third mounting hole is arranged on the lower side wall of the end of the support rod away from the fixed bracket, and the other end of the diagonal support assembly is rotatably connected in the third mounting hole. In the above improved structure, using hollow square tubes as the fixed bracket and the support rod is convenient for installation and has a beautiful appearance; in addition, the hinged connection of the support rod and the diagonal support assembly is realized by arranging corresponding mounting holes on the side wall of the square tube, and this mounting structure does not require adding a hinge seat on the outer wall of the square tube, simplifies the connection structure, and increases the aesthetics.

[0014] Further improved, pin shafts for connecting the support rod and the diagonal support assembly respectively are penetrated through the two side pipe walls of the first mounting hole, the second mounting hole and the third mounting hole. Both ends of the three pin shafts are sleeved with bushings, and one end of each bushing abuts against the two side walls of the part of the support rod or the diagonal support assembly located in the corresponding mounting hole. In the above improved structure, the three hinge joints are positioned by bearings between the two sides of the corresponding rotating parts and the side wall of the mounting hole, reducing noise and ensuring the stability of the movement process of the rotating parts.

[0015] Further improved, one end of the support rod away from the fixed bracket is connected with an installation channel that penetrates up and down, and the upper opening of the installation channel is larger than the lower opening. The lower end of the insertion tube is inserted into the installation channel, the bottom of the insertion tube abuts against the bottom wall of the inner cavity of the support rod, and the lower end of the screw rod extends out of the lower opening of the installation channel; a circular positioning boss is arranged at the lower end of the driving nut, and the positioning boss is fitted in the lower opening of the installation channel.

The driving nut 14 is connected to the bottom of the inner cavity of the insertion tube 3. The adjusting screw 13 is fitted in the driving nut 14, and the upper end of the adjusting screw 13 is connected to the actuator 5. The lower end of the adjusting screw 13 is exposed outside the lower end of the support rod 2. Preferably, a hand-adjusting knob 22 is connected to the lower end of the adjusting screw 13 to facilitate the rotation of the adjusting screw 13.

[0034] Additionally, in the above structure, the driving nut 14 is fixed to the inner wall of the insertion tube 3 by welding. To increase the welding firmness, a plurality of welding windows are provided on the outer peripheral wall at the lower end of the insertion tube 3. A fitting hole is provided at the lower end of the top column. The adjusting screw 13 can be a conventional long bolt. The bolt head portion of the long bolt is located within the fitting hole, and a bottom cover 23 for fixing the bolt head in the fitting hole is provided in the fitting hole. The bottom cover 23 is welded and fixed to the lower end of the top column, and a through hole 7 is provided in the middle of the bottom cover 23.

Preferably, angle values are marked at positions corresponding to each positioning insertion hole 26 on the outer wall of the telescopic inner tube 24. In this embodiment, there are 7 positioning insertion holes 26. When the positioning pin 27 is inserted into the lowermost positioning insertion hole 26, the support rod 2 is in a horizontal state. For each upward adjustment of one positioning insertion hole 26, the support rod 2 is lifted by 5°. That is, the support rod 2 in this structure can be adjusted between 0° and 30° for the speaker.

[0038] In this structure, isolation sleeves are provided between the two side walls of the positioning jack 26 provided on the telescopic inner tube 24 and the corresponding inner walls of the fixed outer tube 25 to prevent the telescopic inner tube 24 from directly contacting the side wall of the fixed outer tube 25 and reduce noise.

Bushings 18 are sleeved on both ends of the three pin shafts 17, and one end of each bushing 18 abuts against the two side walls of the part of the support rod 2 or the diagonal brace assembly located in the corresponding mounting hole. In this structure, the three pin shafts 17 are all locking bolts, and corresponding bushings 18 are sleeved on the outer parts of both ends of each locking bolt. Flange skirts are provided at the ends of the two symmetrically arranged bushings 18 facing away from each other. That is, each bushing 18 is installed from the outside to the inside along the corresponding square tube, and the flange skirt abuts against the outer wall of the fixed bracket 1 or the support rod 2. The other end of the bushing 18 abuts against the corresponding two side walls on the support rod 2 or the telescopic inner tube 24 or the fixed outer tube 25, ensuring the stability of the support rod 2 during the rotation and angle adjustment, and there is no noise during the rotation process.
