Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, and in particular to a muscle relaxation device for swinging arm tapping massage. Background Technology

[0002] As people's pace of life accelerates and work pressure increases, physical fatigue also rises. To effectively relieve muscle fatigue, various muscle relaxation devices have emerged. Common examples include various shoulder, neck, and back massagers, leg massage chairs, fascia guns, and so on.

[0003] Among them, such as Figure 1 The diagram shows a schematic of a conventional multi-head fascia gun 10', where all massage heads are connected to a massage plate body 1'. This design includes two massage arms 2', with their middle sections rotatably connected to both ends of a drive shaft 3', and driven by the drive shaft to move the massage heads at both ends. However, since the middle section of each massage arm is directly connected to the drive shaft, it is both driven and supported by it. While fascia guns typically have handles for handheld use, depending on the area being massaged, they sometimes need to be pressed under the limb or behind the backrest for massage, such as by stepping on the foot, pressing against the leg, or leaning against the back. Under these massage methods, the massage arms are subjected to prolonged pressure, easily damaging the connecting bearing 4' between the massage arms and the drive shaft, resulting in a short product lifespan and a poor user experience, requiring urgent improvement.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] like Figures 2 to 9 As shown, a muscle relaxation device 10 for swing arm tapping massage in this embodiment includes a device base 1, a swing arm 2, a support shaft 3, and a drive shaft 4.

[0032] See Figure 4 The swing arm 2 is oscillatingly mounted inside the device base 1. The swing arm 2 includes a rotating part 21 and a swing support arm 22. The swing support arm 22 extends outward from one side of the rotating part 21, and the end of the swing support arm 22 extends upward to form a massage head connection part 23. The massage head connection part 23 extends out of the device base 1 and is used to connect the massage head 5.

[0033] The supporting shaft 3 and the drive shaft 4 are parallel to each other and spaced apart, and are both rotatably mounted in the device base 1; a cam device 6 is connected to the drive shaft 4.

[0034] The rotating part 21 of the swing arm 2 is rotatably connected to the supporting shaft 3; the lower end of the swing arm 22 of the swing arm 2 is connected to the cam device 6, and the drive shaft 4 is used to drive the cam device 6 to rotate. The cam device 6 drives the swing arm 22 to swing around the supporting shaft 3.

[0035] Therefore, when using the muscle relaxation device 10 for massage and relaxation, the rotation of the drive shaft 4 can drive the cam device 6 to rotate, which in turn drives the swing arm 22 to swing around the pivot 3 supported at the rotating part 21, thereby realizing the up and down swing of the massage head 5 installed on the massage head connection part 23 on the swing arm 2. This realizes the tapping massage action of the swing arm 2, which can tap the muscles of various parts of the body to relax and relieve tense muscles.

[0036] In this embodiment, the support shaft and the swing shaft of the swing arm 2 are separated. The rotating part 21 of the swing arm 2 is supported by the support shaft 3 installed in the device base 1, and the swing of the swing arm 2 is driven by the cam device 6 and the drive shaft 4 below the swing arm 22 away from the rotating part 21. When the swing arm 2 is under pressure, the pressure can be shared by the rotating part 21 and the support shaft 3, which greatly reduces the pressure on the cam device 6 at the drive shaft 4, reduces the probability of damage to the cam device 6 and the drive shaft 4, and effectively improves the service life of the product.

[0037] Specifically, in this embodiment, there are two swing arms 2 arranged symmetrically on the left and right; two supporting shafts 3 are arranged spaced apart on the left and right; and the drive shaft 4 extends in the left and right direction, with a cam device 6 sleeved and connected to each of the left and right ends of the drive shaft 4. Of course, there can also be only one swing arm 2, which can also realize the massage function. Setting two swing arms 2 can make the massage effect better.

[0038] Furthermore, in this embodiment, the rotating part 21 of the swing arm 2 is provided with a swing arm 22 on both the front and rear sides, and the rotating part 21 is centrally located between the two swing arms 22; thus, this embodiment can have four massage head connection parts 23, and the multi-head massage effect is better.

[0039] The swing arm 2 has only one swing arm 22 connected to the cam device 6 at the bottom to realize the corresponding swing and knocking function.

[0040] like Figure 3 and Figure 6As shown, the cam device 6 in this embodiment includes an eccentric cover 61, an eccentric seat 62, a bearing 63, a connecting rod seat 64, and a connecting rod cover 65. The eccentric cover 61 is for the drive shaft 4 to pass through eccentrically and be fixed therethrough. The rotation of the drive shaft 4 causes the eccentric cover 61 to rotate synchronously. The eccentric seat 62 is detachably connected to the eccentric cover 61, and an annular bearing groove 66 is formed between them. The bearing 63 is fitted inside the annular bearing groove 66. The connecting rod seat 64 and the connecting rod cover 65 are detachably fitted around the outer periphery of the bearing 63 along the axial direction of the bearing 63. The top of the connecting rod seat 64 has a connecting lug 641 protruding from it. The connecting lug 641 can be rotatably connected to the lower part of the swing arm 22 via the shaft 642. Thus, when the drive shaft 4 rotates, it can drive the eccentric cover 61 and the eccentric seat 62 to rotate, thereby driving the bearing 63 to rotate eccentrically, so as to drive the connecting rod seat 64 to move up and down, and thus drive the swing arm 22 to swing about the rotating part 21 as the axis.

[0041] Specifically, it can be as follows Figure 3 As shown, the muscle relaxation device 10 of this embodiment may also include a motor 71, a motor mounting base 72, a battery 73, a silicone sleeve 8, and a support base 9.

[0042] In this embodiment, the device base 1 includes an upper cover 11 and a lower base 12 that are detachably connected, forming an installation space 13 between the upper cover 11 and the lower base 12; the swing arm 2, the support shaft 3, the drive shaft 4, the motor 71 and the battery 73 can all be installed on the lower base 12 within the installation space 13, and the massage head connection part 23 of the swing arm 2 extends out from the upper cover hole 111 provided on the upper cover 11; the upper cover 11 and the lower base 12 are combined to facilitate the assembly of the product.

[0043] A silicone sleeve 8 may also be provided at the upper cover hole 111. The silicone sleeve 8 is fitted around the outer periphery of the massage head connecting part 23 and can fill the gap between the massage head connecting part 23 and the upper cover hole 111 to prevent fingers from being pinched.

[0044] In this embodiment, the device base 1 may have a supporting shaft mounting seat 121, which may be formed on the lower base 12. The supporting shaft mounting seat 121 may have a recessed swing groove 122 extending forward and backward in the middle. The left and right side walls of the swing groove 122 are respectively provided with rotating holes 123, and the two ends of the supporting shaft 3 pass through the rotating holes 123. The rotating part 21 of the swing arm 2 is oscillatingly accommodated in the swing groove 122, and the rotating part 21 is provided with a shaft hole 211 for the supporting shaft 3 to pass through. The supporting shaft mounting seat 121 can improve the support effect on the supporting shaft 3, and the swing groove 122 can also increase the support effect on the swing arm 2.

[0045] In this embodiment, the motor 71 is connected to the drive shaft 4 and electrically connected to the battery 73, which can be used for power supply. Alternatively, it can be directly powered by mains power. Specifically, the motor 71 can be mounted on the side of the motor mounting base 72 by screws. The bottom surface of the motor mounting base 72 can be detachably connected to the device base 1 by screws. The motor mounting base 72 is made of heat-resistant material.

[0046] By separating the motor mounting base 72 and the lower base 12, the motor mounting base 72 can be made of heat-resistant materials, such as nylon, while the lower base 12 and the upper cover 11 can be made of ABS material. In this way, the motor 71, which generates a lot of heat, can directly contact the heat-resistant motor mounting base 72 and dissipate heat, thus avoiding the deformation and damage to the device base 1 caused by directly installing it on the heat-sensitive lower base 12.

[0047] In this embodiment, the drive shaft 4 extends left and right through the motor 71 and is driven by the motor 71 to rotate; the cam device 6 is sleeved on both the left and right ends of the drive shaft 4.

[0048] For example Figures 5 to 9 As shown, the massage head connection part 23 protrudes from the top surface of the middle part of the device base 1 in this embodiment and a massage head 5 is installed thereon; handles 14 can be formed on both sides of the device base 1 respectively, and a handle hole 15 is provided between the handle 14 and the middle part of the device base 1; so that the user can carry it by hand for convenient use.

[0049] The support base 9 is detachably assembled to the bottom of the device base 1, and the top surface of the support base 9 protrudes to form two limiting parts 91, which are inserted into the handle hole 15. The support base 9 is provided so that the muscle relaxation device 10 can be placed on the ground for use. The support base 9 supports the muscle relaxation device 10 and can play a role in cushioning and shock absorption.

[0050] For example Figure 2 , Figure 7 and Figure 8 As shown, the massage head 5 includes a tapping massage head assembly 51, a leg massage head assembly 52, and a back massage head assembly 53, which are selectively installed.

[0051] like Figure 2 The tapping massage head assembly 51 includes four conical massage heads 511, each detachably mounted on the massage head connector 23; as Figure 7 The leg massage head assembly 52 includes two massage plates 521, one on the left and one on the right. The massage plates 521 extend forward and backward, and their bottoms are respectively connected to the two massage head connecting portions 23 of the swing arm 2 on the same side. Figure 8The back massage head assembly 53 includes two massage blocks 531 on the left and right sides. The massage blocks 531 extend forward and backward and their bottoms are respectively connected to the two massage head connecting parts 23 of the swing arm 2 on the same side.
