Optionally, the rotation connecting assembly 70 further includes a limiting component 73, the limiting component 73 is disposed on the first connecting member 71, the limiting component 73 has a first locking portion 731 and a second locking portion 732 facing the second connecting member 72, the second connecting member 72 has a fastening portion 721 matched with the first locking portion 731 and the second locking portion 732, and the second connecting member 72 can rotate relative to the first connecting member 71 to fasten the fastening portion 721 to the first locking portion 731 or the second locking portion 732. It can be understood that when the fastening portion 721 is fastened to the first fastening portion 731, the neck massager 100 is in a use state, and at this time, the angle between the clamping arm 30 and the middle bracket 10 is fixed and can not rotate, so as to prevent the clamping arm 30 from loosening relative to the middle bracket 10 and affecting the wearing effect when the neck massager 100 is worn on the neck of a user, and when the fastening portion 721 is fastened to the second fastening portion 732, the fastening portion 721 can slide relative to the second fastening portion 732, and at this time, the clamping arm 30 can rotate relative to the bracket, so that the neck massager 100 can be switched to a storage state. That is, when the neck massager 100 is in the storage state, the buckle portion 721 can slide in the second locking portion 732, so the included angle of the first clamping arm 31 relative to the middle bracket 10 and the included angle of the second clamping arm 32 relative to the middle bracket 10 can be different, and when the neck massager 100 is in the storage state, the positions and the storage sequence of the first clamping arm 31 and the second clamping arm 32 can be reversed, thereby having the foolproof effect. Illustratively, the position limiting member 73 may be a position limiting bracket having a hollow portion.
That is, when the user uses the neck massager 100 to perform massage, the clamping arms 30 can be rotated relative to the middle support 10 to switch the neck massager 100 from the storage state to the use state, and at this time, the second connecting member 72 rotates relative to the first connecting member 71 and the angle of the fastening portion 721 relative to the second fastening portion 732 changes, and the fastening portion 721 slides from the second fastening portion 732 to the first fastening portion 731 to be fastened with the first fastening portion 731. When the user takes in the neck massager 100, the clamping arms 30 can be rotated relative to the middle support 10 to switch the neck massager 100 from the use state to the storage state, at this time, the second connecting member 72 rotates relative to the first connecting member 71 and the fastening portion 721 slides from the first fastening portion 731 to the second fastening portion 732, at this time, the fastening portion 721 can slide relative to the second fastening portion 732, and by further rotating the clamping arms 30, the clamping arms 30 can be rotated until the neck massager 100 is in the storage state.
In some embodiments, the wire through hole 70a has a first wall 701 near the outer side of the clamping arm 30, and a side of the protective sheath 50 facing the outer side of the clamping arm 30 abuts against the first wall 701. It can be understood that when the clamping arm 30 rotates relative to the second connecting member 72 and the middle bracket 10 along with the first connecting member 71 until the neck massage apparatus 100 is in the storage state, a gap is formed between the clamping arm 30 and the first connecting member 71, and when the protective sleeve 50 rotates relative to the middle bracket 10 along with the clamping arm 30 and is bent, one surface of the protective sleeve 50 facing to the outer side of the clamping arm 30 can further be close to the first wall 701, and at this time, the protective sleeve 50 can seal the communication between the wire passing hole 70a and the gap, thereby effectively preventing foreign objects such as dust, water and the like from entering the interior of the clamping arm 30 and the interior of the middle bracket 10 from the wire passing hole 70a through the gap, and causing the neck massage apparatus 100 to be damaged.
Further, the wire through hole 70a has a second wall 702 near the inner side of the clamping arm 30, and the second wall 702 is provided with an avoiding groove 70b, and the avoiding groove 70b is used for avoiding the protective sleeve 50 when the clamping arm 30 rotates relative to the intermediate bracket 10. It can be understood that, by providing the avoiding groove 70b, when the protective sleeve 50 is bent along with the rotation of the clamping arm 30 relative to the middle bracket 10, the avoiding groove 70b can avoid the protective sleeve 50, so as to avoid the protective sleeve 50 from contacting the second wall 702 in a whole surface, thereby reducing the contact area, reducing the resistance of the protective sleeve 50 to bending (the friction force generated by the second wall 702 on the protective sleeve 50), further reducing the degree of abrasion of the protective sleeve 50 when being bent, and prolonging the service life of the neck massager 100.
For example, a section of the protective sheath 50 at the opening of the middle bracket 10 may be configured to have a larger cross section so as to be completely filled and matched with the opening of the middle bracket 10, thereby preventing foreign materials such as dust, water, etc. from entering the middle bracket 10 as much as possible. Illustratively, the length of the section of the protective sleeve 50 with a larger cross section may be 2mm to 5mm, so as to reduce the contact area between the protective sleeve 50 and the middle support 10, and effectively prevent the occurrence of the situation that when the clamping arm 30 rotates relative to the middle support 10, the protective sleeve 50 is blocked to generate wrinkles, which further affects the expansion of the clamping arm 30 relative to the middle support 10. The principle of the protective sheath 50 having a larger cross section and a shorter length to reduce the contact area between the protective sheath 50 and the middle support 10 can be referred to as follows: when the shaft hole is in interference fit, the smaller the length of the shaft in the hole is, the smaller the contact area between the outer surface of the shaft and the inner surface of the hole is.
In some other embodiments, a section of the protective sleeve 50 located at the opening of the clamping arm 30 can refer to the arrangement manner of the protective sleeve 50 located at one end of the opening of the middle bracket 10, so as to prevent foreign matters such as dust and water from entering into the clamping arm 30 as much as possible, and at the same time, effectively prevent the clamping arm 30 from generating wrinkles due to the larger resistance of the protective sleeve 50 when rotating relative to the middle bracket 10, and further prevent the occurrence of an influence on the expansion of the clamping arm 30 relative to the middle bracket 10.
The embodiment of the utility model provides a neck massager 100, inboard through middle support 10 sets up massage subassembly 20, set up power supply unit in the arm lock 30 and pass through conductor wire 40 to massage subassembly 20 power supply, support 10 rotates in the middle of arm lock 30 relatively, be convenient for accomodate neck massager 100, at least, conductor wire 40 rotates along with arm lock 30 relatively middle support 10 and takes place the part cover of buckling and establish protective sheath 50, and protective sheath 50 can take place to buckle along with conductor wire 40, thereby conductor wire 40 rotates along with arm lock 30 relatively middle support 10 and takes place the part of buckling and can receive protective sheath 50's protection and avoid taking place because of the condition of buckling and wearing and tearing many times, neck massager 100's life is longer.
