Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a silent gravity ring. Background Technology

[0002] In the wave of national fitness, wrist strength has become a bottleneck and key to protection in most training movements. To specifically strengthen the wrist flexor and extensor muscles, common equipment on the market includes wrist exercisers, weighted rings, wrist balls, and wrist rings. Among them, the core mechanism of wrist balls and wrist rings is that the heavy rotor (counterweight ball) inside the ring is driven by inertia to rotate continuously. Its centrifugal reaction force is transmitted to the wrist through the ring body, forming a dynamic load, forcing the forearm muscles to continuously resist, thereby achieving a simultaneous improvement in wrist strength and grip strength.

[0003] Current gravity ring designs generally employ a "bare ball-raceway" structure. Because the shell constituting the raceway is relatively thin, a high-density metal counterweight ball is placed within a closed annular cavity made of ABS or PC material, using a clearance fit. The outer surface of the ball and the inner wall of the cavity rely solely on a very thin boundary lubrication layer formed by a small amount of grease, failing to create a continuous oil film. Therefore, during the ball's movement, the contact with the wall surface exhibits intermittent hard friction, resulting in significant noise and negatively impacting the user experience of the gravity ring. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a silent gravity ring.

[0005] The technical solution adopted by this utility model is as follows:

[0006] This application provides a silent gravity ring, including a housing and a counterweight rotor component;

[0007] The housing has an annular rolling channel, and the counterweight rotor component is rolled within the rolling channel;

[0008] The counterweight rotor component includes a counterweight body and a sound-absorbing layer covering the surface of the counterweight body.

[0009] A sound-absorbing layer is placed on the surface of the counterweight to reduce or even absorb the noise generated when it rolls. This meets the requirement of "silent wearability," ensuring that it will not disturb others' sleep, even when used at night.

[0010] Furthermore, a sound insulation layer is provided on the side wall of the shell forming the rolling channel, which is used to reduce the noise generated when the counterweight comes into contact with the shell during rolling;

[0011] The sound insulation layer is a sound-absorbing layer, an elastic damping layer, or a combination of a sound-absorbing layer and an elastic damping layer. When the sound insulation layer is a combination of a sound-absorbing layer, the sound-absorbing layer is located on the side closer to the shell.

[0012] The sound-absorbing layer is an elastic damping layer.

[0013] A sound-insulating layer is installed within the rolling channel to absorb noise generated by the counterweight rotor components during rolling. In practical use, the elastic damping layer provides vibration attenuation, and the sound-absorbing layer provides sound wave dissipation. The sound-absorbing layer can be a sound-absorbing sponge layer, and the elastic damping layer can be a soft rubber layer, specifically a rubber layer or a damping rubber layer.

[0014] Furthermore, it also includes a light-emitting fiber, a light source, and a power supply electrically connected to the light source;

[0015] An installation space is also formed inside the housing, the installation space is located outside the rolling channel, and the light source and power supply are disposed within the installation space.

[0016] The housing has mounting holes that connect the mounting space to the outside of the housing.

[0017] The light-emitting fiber is disposed on the mounting hole. One side of the light-emitting fiber has an unobstructed light path between it and the light source, while the other side is exposed outside the housing. When the light source is turned on, the emitted light from the light source can couple into the fiber and make the light-emitting fiber emit light.

[0018] Furthermore, the housing also has a handle formed on the outside of the mounting space, the handle being arranged radially along the annular rolling channel.

[0019] Furthermore, a partition is provided between the installation space and the rolling channel, and the partition has openings;

[0020] It also includes a counter having a sensor installed in the mounting space, with the sensor's probe located at an opening to sense the movement of the counterweight rotor component.

[0021] Furthermore, the housing has a viewing hole at the handle position;

[0022] It also includes a display screen, which is located at the viewing hole and connected to the counter signal. The display screen is used to display the motion information of the counterweight rotor component.

[0023] Furthermore, the housing includes an upper shell and a lower shell that interlock with each other, and the upper shell and the lower shell are respectively provided with connecting protrusions;

[0024] The connecting protrusion has connecting holes on the inner and outer sides of the annular rolling channel, respectively.

[0025] The connection hole is used to engage with fasteners to secure the upper and lower shells.

[0026] Furthermore, the housing has at least two sets of spaced-apart connecting protrusions;

[0027] The upper shell and the lower shell are respectively provided with grooves on their respective body walls for engaging with the lower shell. When the upper shell and the lower shell are fastened together, the grooves of the upper shell and the lower shell are positioned opposite each other to form mounting holes.

[0028] Furthermore, the connecting protrusion is a semi-annular connecting protrusion, and the connecting protrusion has a first slot;

[0029] It also includes a collar, with a locking block on the inner side of the collar. The collar is sleeved on the connecting protrusion, and the locking block cooperates with the first locking groove to fasten the collar to the connecting protrusion.

[0030] Furthermore, the first slot is provided on the connecting protrusion of the upper shell, and the connecting protrusion at the lower shell position has a second slot;

[0031] The collar has a first connecting end and a second connecting end that are circumferentially connected. The first connecting end is a tongue that extends circumferentially and has a third slot. The second connecting end is a slot that is adapted to the tongue and has a limiting block.

[0032] The tongue is inserted into the slot, and the limiting block is engaged in the third slot, so that the collar is closed into a continuous ring.

[0033] When the collar is fitted onto the connecting protrusion, the second slot provides accommodating space for the tongue and the locking block.

[0034] The beneficial effects of this utility model are:

[0035] (1) A sound insulation layer is set in the rolling channel, or a sound-absorbing layer is also set on the surface of the counterweight rotor component to absorb the noise emitted when the counterweight rotor component rolls, so as to meet the "silent wear" requirement and not disturb others' sleep even when used at night.

[0036] (2) By providing light-emitting fibers on the outer shell, the gravity ring of this application can be used at night.

[0037] (3) Two sets of annular connecting protrusions are set on the outer shell and fixed with two sets of fasteners. With the addition of a set of fasteners at the handle position, only three sets of fasteners are needed to securely fix the upper shell and the lower shell after ultrasonic welding.

[0050] The present invention will now be described in detail with reference to the accompanying drawings.

[0051] like Figures 1-10 As shown, this application provides a silent gravity ring, including a housing 10 and a counterweight rotor component 20;

[0052] The housing 10 has an annular rolling channel 101, and the counterweight rotor component 20 is rolled within the rolling channel 101;

[0053] The counterweight rotor component 20 includes a counterweight body 210 and a sound-absorbing layer 220 covering the surface of the counterweight body 210.

[0054] A sound-absorbing layer is placed on the surface of the counterweight to reduce or even absorb the noise generated when it rolls. This meets the requirement of "silent wearability," ensuring that it will not disturb others' sleep, even when used at night.

[0055] In addition, a sound insulation layer 110 is provided on the side wall of the housing 10 that forms the rolling channel 101. The sound insulation layer 110 is used to reduce the noise generated when the counterweight 210 comes into contact with the housing 10 during rolling.

[0056] A sound insulation layer 110 is provided in the rolling channel 101 to absorb the noise generated when the counterweight rotor component 20 rolls.

[0057] In this embodiment, the sound insulation layer 110 is a sound-absorbing layer, an elastic damping layer, or a superimposed combination of a sound-absorbing layer and an elastic damping layer. When the sound insulation layer 110 is a superimposed combination layer, the sound-absorbing layer is disposed on the side close to the housing 10.

[0058] The sound-absorbing layer 220 is an elastic damping layer.

[0059] In practical applications, the elastic damping layer provides vibration attenuation, while the sound-absorbing layer provides sound wave dissipation. The sound-absorbing layer can be a sound-absorbing sponge layer, and the elastic damping layer can be a soft rubber layer, specifically a rubber layer or a damping rubber layer.

[0060] In other embodiments, a sound insulation layer 110 may be provided separately on the side wall of the housing 10 or a sound-absorbing layer 220 may be provided separately on the surface of the counterweight 210.

[0061] In this embodiment, the counterweight rotor component 20 is a counterweight ball, and the cross-sectional shape of the rolling channel 101 is adapted to the cross-sectional shape of the counterweight ball.

[0062] like Figures 2-4 As shown, in this embodiment, it also includes a light-emitting fiber body 30, a light source 40, and a power supply 50 electrically connected to the light source 40;

[0063] An installation space 102 is also formed inside the housing 10. The installation space 102 is located outside the rolling channel 101. The light source 40 and the power supply 50 are disposed inside the installation space 102.

[0064] The housing 10 has a mounting hole 103, which connects the mounting space 102 with the outside of the housing 10;

[0065] The light-emitting fiber 30 is disposed on the mounting hole 103. One side of the light-emitting fiber 30 has an unobstructed light path between it and the light source 40, while the other side is exposed outside the housing 10. When the light source 40 is turned on, the emitted light from the light source 40 can couple into the fiber and make the light-emitting fiber 30 emit light.

[0066] In this embodiment, the installation space 102 is located inside the annular rolling channel 101.

[0067] In this embodiment, the housing 10 also has a handle 120 formed on the outside of the mounting space 102, and the handle 120 is arranged radially along the annular rolling channel 101.

[0068] In this embodiment, the housing 10 forming the rolling channel 101 is an annular ring structure, and the handle 120 is disposed on the inner side of the annular ring structure.

[0069] In this embodiment, a partition 130 is provided between the installation space 102 and the rolling channel 101, and the partition 130 has an opening 131.

[0070] like Figure 4 As shown, it also includes a counter 70, which has a sensor installed in the mounting space 102, with the sensor's probe located at the opening 131 to sense the movement of the counterweight rotor component 20.

[0071] In this embodiment, the housing 10 has a viewing hole 121 at the handle 120 position;

[0072] It also includes a display screen, which is located at the viewing hole 121 and is signal-connected to the counter 70. The display screen is used to display the motion information of the counterweight rotor component 20.

[0073] In this embodiment, the sensor is a non-contact rotation counting sensor, specifically a Hall effect sensor (in this case, the counterweight rotor component 20 is a metal counterweight rotor component 20).

[0074] In other embodiments, the sensor may also be an accelerometer. The accelerometer senses the change in centripetal force at the location of the counterweight rotor component 20 as it moves along the annular rolling channel 101 and generates a recording signal. The recording signal includes the speed of movement of the counterweight rotor component 20 and the magnitude of the centripetal force. The mass of the counterweight rotor component 20 is determined. The value of the centripetal force is measured by the accelerometer, and the moving speed of the gravity ball is calculated by the main control chip electrically connected to the accelerometer. The main control chip displays the value of the moving speed of the counterweight rotor component 20 and the magnitude of the centripetal force on the display screen.

[0075] In this embodiment, the housing 10 includes an upper housing 140 and a lower housing 150 that are interlocked with each other, and the upper housing 140 and the lower housing 150 are respectively provided with connecting protrusions 141;

[0079] The upper shell 140 and the lower shell 150 are respectively provided with grooves 142 on their respective body walls for cooperating with the lower shell 150. When the upper shell 140 and the lower shell 150 are fastened together, the grooves 142 of the upper shell 140 and the grooves 142 of the lower shell 150 are arranged opposite to each other to form a mounting hole 103.

[0080] In this embodiment, the light-emitting fiber body 30 includes a connecting part and a light-emitting part connected together. The connecting part is snapped or bonded between the upper shell 140 and the lower shell 150, and the light-emitting part is located in the mounting hole 103.

[0081] In this embodiment, there are two sets of mounting holes 103, located on both sides of the handle 120.

[0082] In this embodiment, the connecting protrusion 141 is a semi-circular connecting protrusion 141, and the connecting protrusion 141 has a first slot 1412;

[0083] It also includes a collar 60, and a locking block 610 is provided on the inner side of the collar 60. The collar 60 is sleeved on the connecting protrusion 141, and the locking block 610 cooperates with the first locking groove 1412 to fasten the collar 60 to the connecting protrusion 141.

[0084] In this embodiment, the first slot 1412 is provided on the connecting protrusion 141 of the upper shell 140, and the connecting protrusion 141 at the lower shell 150 has a second slot 151.

[0085] The collar 60 has a first connecting end 620 and a second connecting end 630 that are connected to each other. The first connecting end 620 is a tongue that extends circumferentially and has a third slot 621. The second connecting end 630 is a slot that is adapted to the tongue and has a limiting block 631.

[0086] The tongue is inserted into the slot, and the limiting block 631 is engaged in the third slot 621, so that the collar 60 is closed into a continuous ring.

[0087] When the collar 60 is attached to the connecting protrusion 141, the second slot 151 provides space for the tongue and the locking block 610.

[0088] In this embodiment, the limiting block 631 includes a connecting part and a limiting part. The connecting part is connected to the slot and disposed in the third slot 621. The limiting part is connected to the connecting part and disposed inside and outside the third slot 621. The radial dimension of the limiting part is larger than the radial dimension of the third slot 621.

[0089] In this embodiment, the collar 60 is made of elastic rubber.

[0090] In this embodiment, the shell 10 is a plastic shell 10 (ABS or PC), and the upper shell 140 and the lower shell 150 are integrally formed.

[0091] In this embodiment, a fastener is also included. The upper shell 140 has a connecting post 143 in the mounting space 102 at the handle 120 position. The connecting post 143 has a connecting hole 1411. The lower shell 150 also has a connecting hole 1411 at the corresponding position of the connecting post 143. The fastener further fixes the upper shell 140 and the lower shell 150 through the two connecting holes 1411.

[0092] In this embodiment, the handle 120 is fixed by two fasteners. There are two sets of connecting protrusions 141, and each set of connecting protrusions 141 is fixed by two fasteners. That is, the upper shell 140 and the lower shell 150 are fixed by ultrasonic welding and then fixed by 6 fasteners, without the need for a full circle of fasteners.
