Problems solved by technology
[0002] Speakers are generally placed by ground nails and foot pads fixed at the bottom to reduce the impact of vibration on sound quality. The movement of speakers is usually carried by hand, and speakers are usually heavy and very troublesome to carry. Adding traditional casters at the bottom of the speaker will affect the sound effect of the speaker, so it is necessary to design a silent caster that is convenient for speaker handling

Embodiment Construction
[0019] refer to Figure 1 to Figure 4 , Figure 1 to Figure 4 It is a structural schematic diagram of a specific embodiment of the present invention. As shown in the figure, a silent caster wheel includes a base 1, a bracket 2 rotatably arranged below the base 1, and a roller 3 rotatably arranged on the bracket 2. Preferably, in In this embodiment, the roller 3 is made of elastic materials such as rubber material, PU material, PVC material, nylon material, PP material or EVA material, etc., and the roller 3 is arranged on the bracket 2 through the rotation of the pin 31 and the bearing 32. The base 1 is provided with a rotating bearing 11 , and the support 2 is pierced with a shaft nail 21 , and the upper part of the shaft nail 21 is fixed to the inner ring of the rotating bearing 11 .
[0020] As shown in the figure, a sound-absorbing pad 4 is arranged between the base 1 and the bracket 2, and the sound-absorbing pad 4 is made of elastic materials such as rubber material, PU...

The invention provides a muting castor comprising a base, a support rotatably arranged under the base and a rolling wheel arranged on the support rotatably. A sound absorption pad made of elastic materials such as rubber, PU, PVC, nylon, PP, or EVA is arranged between the base and the support. During use, the castor is installed at the bottom of a loudspeaker box for facilitating the carrying of the loudspeaker box; the sound absorption pad has a shocking-proof function, so that components in the loudspeaker box are prevented from getting damaged; after the carrying is completed; the castor is suspended by rotating a lifting ground screw at the bottom of the loudspeaker box. During use of the loudspeaker, the sound absorption pad can increase the rotation resistance between the base and the support to prevent relative rotation of the base and the support, so that the sound effect of the loudspeaker box will not be influenced by vibration or resonance generated by the castor and the tone quality will not be influenced by noise generated at the castor. The muting castor facilitates the carrying of loudspeaker boxes, guarantees the normal sound effect of the loudspeaker boxes, and has a higher practical and promotional value.
Description
technical field [0001] The invention relates to a mute caster wheel applied to a sound box. Background technique [0002] Speakers are generally fixed on the bottom with nails, foot pads, etc. to reduce the impact of vibration on sound quality. The movement of speakers is usually carried by hand, and speakers are usually heavy, and handling is very troublesome. If it is directly Adding traditional casters at the bottom of the speaker will affect the sound effect of the speaker, so it is necessary to design a silent caster that is convenient for the speaker to carry. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a silent caster wheel which is convenient for carrying the sound box. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A silent caster, comprising a base, a bracket rotatably arranged under the base, and rollers rotatably arranged on the...
