Description

Technical Field

[0001] This utility model relates to the field of speakers, and more specifically, to a stand and a speaker. Background Technology

[0002] Currently, many speakers on the market come with displays that offer various functions such as song selection, prompting, and video playback. These displays are mainly installed in two ways: one is by fixing them directly to the speaker, which is not adjustable and significantly limits the viewing experience; the other is by using a stand to support the display, allowing it to swing, making it easy to store and providing a better viewing experience.

[0035] like Figures 1 to 4As shown, a bracket is disclosed in a specific embodiment of the present invention, including a support arm 300, a first support seat 100 and a second support seat 200 respectively rotatably mounted at both ends of the support arm 300, a first support plate 110 rotatably mounted on the first support seat 100, and a second support plate 210 rotatably mounted on the second support seat 200. Each of the above-mentioned rotating parts is provided with a spring for increasing damping friction.

[0036] The aforementioned bracket features multiple movable joints, allowing for multi-angle rotation and flipping. Springs are added to the joints to increase force and provide sufficient frictional damping for locking, preventing loosening.

[0037] Furthermore, such as Figures 4 to 6 As shown, the first support base 100 includes a first support plate 110, a first bracket 120, a first spring 130, a first sleeve 140, and a first limiting assembly 150; the first bracket 120 is rotatably mounted on one end of the support arm 300; the first support plate 110 has a first through hole 111 in the middle, and the first bracket 120 has a corresponding second through hole 121; a first limiting ring is fixedly provided on the outer wall of one end of the first sleeve; the first support plate is located on one side of the first bracket, the first sleeve 140 passes through the first through hole 111 and the second through hole 121, and the first limiting ring abuts against the wall of the first support plate; the outer wall of the first sleeve is provided with a screw... The first support plate has a first nut installed at its end; the edge of the first support plate is rotatably connected to the first bracket via a first limiting component; the first spring 130 is sleeved on the first sleeve 140 and clamped between the first nut 141 and the first bracket 120; this structural design allows the first support plate to be rotatably mounted on the first bracket, and the friction between the first bracket and the first support plate is enhanced by the first spring, so that the two have better frictional damping, so that the first support plate can be maintained in the required placement position; in addition, the first bracket is rotatably mounted on the support arm, and the rotation direction is different from the rotation direction of the first support plate, which can provide another adjustment direction and expand the applicability.

[0038] Furthermore, such as Figure 3As shown, the first limiting component 150 includes a first limiting member 151 and a second limiting member 152. The first limiting member 151 is mounted on the first support plate 110, and the second limiting member 152 is mounted on the first bracket 120. The second limiting member is located on the side of the first limiting member away from the first support plate. The second limiting member 152 is rotatably engaged with the first limiting member 151 and provides a limiting stop for the first limiting member. The first limiting member has a rectangular block structure, and a first circular hole is provided in the middle of the first limiting member. The diameter of the first circular hole is larger than the maximum length of the first bracket. A groove is provided on the side of the first limiting member away from the first bracket.

[0043] Furthermore, such as Figure 7 As shown, two support tubes 220 are fixedly installed at the top of one end of the second support base 200, with a gap between the two support tubes, and a first support ring 230 is fixedly installed at the distal end of the support tube 220; second support blocks 320 are fixedly installed on both sides of the support arm 300 near the second support base, and a fifth through hole 321 is provided on the second support block 320; a second support bolt 610 is installed through the fifth through hole 321 and the first support ring 230, and the first support ring 230 slides against the wall surface of the second support block 320; a third spring 620 is installed on the second support bolt 610, and the third spring 620 is clamped in the first support ring 230. Between 0 and the second locking nut 630; this structure allows the support tube to be rotatably mounted on the second support block, and the friction of the mating parts is increased by the third spring, thereby providing sufficient frictional damping to achieve the required locking effect and keep the support arm in the required position; wherein, the edge of the fifth through hole is provided with a second slot, and the head edge of the second support bolt is correspondingly fixed with a second locking block, the second locking block is locked in the second slot to prevent the second support bolt from rotating and keep it in a stationary state, and the frictional rotation of other components makes the frictional force generated by the third spring have a better damping effect.

[0044] Furthermore, the second support block 320 is provided with a second threaded hole 322, and a second guide bolt 520 is installed at the second threaded hole 322; the first support ring 230 is provided with a corresponding second guide hole 231, which extends along the rotation trajectory; the end of the second guide bolt is a smooth rod structure and is adapted to extend into the second guide hole; this design can limit the extreme placement position of the support arm, and can also use the obstruction of movement as a reminder that the adjustment is in place; when the second support seat rotates and swings until the second guide bolt is stuck at the end of the second guide hole, the support arm is at the maximum extended position or the retracted position, which serves as a positioning reminder and facilitates adjustment and use.

[0045] Furthermore, such as Figure 8As shown, a pressure plate 240 is fixedly installed on the inner side of the bottom of the second support base 200 away from the support tube, and a sixth through hole 241 is provided on the pressure plate 240; a corresponding seventh through hole 211 is provided on the second support plate 210; the bottom surface of the pressure plate abuts against the top surface of the second support plate, and a second sleeve 250 is installed through the sixth through hole 241 and the seventh through hole 211. A second limiting ring is fixedly installed on the outer wall of the bottom end of the second sleeve, and the second limiting ring abuts against the bottom surface of the second support plate; the outer wall of the second sleeve is threaded, and a second nut is installed at the top end of the second sleeve; a fourth spring 260 is sleeved on the second sleeve 250, and the fourth spring 260 is clamped in the second thread.

When the second support is rotated to its two placement positions, the ball bearing and the locking holes cooperate to remind the second support to swing into place, which is convenient for adjustment and use;

[0046] It should be noted that a first shielding component is installed between the two first support blocks, and a second shielding component is installed between the two support tubes. The first and second shielding components are used to shield the mating connection parts in the corresponding areas to maintain the overall aesthetics and protect the internal wiring. Assembly is mainly carried out through the snap-fit ​​connection direction, and the specific structure will not be described in detail.
