Description

Technical Field

[0001] This invention relates to the field of human massage and health care instruments, and in particular to a massage and health care instrument that can adjust the width and narrowness of the clamp according to the size of the massage area. Background Technology

[0002] On April 1, 2022, the applicant filed a patent application with the China National Intellectual Property Administration, with patent number 202210338778.8, publication number CN114557873A, entitled "A Multi-Adjustable Clamping Type Ultrasonic Medication Massage Device". This device includes a fixed arm, a sliding arm, a fixed crossbar, ultrasonic medication massage heads, and a sliding crossbar. The fixed arm and sliding arm are respectively mounted on both ends of the sliding crossbar. The sliding arm can slide and adjust along the sliding crossbar to adjust the clamping space between the two ultrasonic medication massage heads. After the sliding arm is adjusted to a suitable position, it is locked using a locking mechanism. While this solution allows users to easily adjust the clamping space between the two ultrasonic massage heads as needed, and features a simple structure, relatively easy operation, and stable and safe clamping, it suffers from a drawback. The sliding arm, after being adjusted to the appropriate position, is locked using a locking mechanism. This locking mechanism, consisting of a sliding groove, a locking nut, and a bolted locking block, is a purely manually operated mechanism. Therefore, adjusting, locking, or unlocking requires both hands; it cannot be operated with one hand. However, in practical applications, the instrument needs to be clamped onto a part of the body before the clamping force can be adjusted based on the user's comfort. Adjustments and locking are only made when the user feels the clamping is not secure enough or the clamping force is insufficient. In certain applications and specific angles, the simultaneous operation of the instrument with both hands is limited by the operating angle. In such cases, because the locking mechanism is purely manual, convenient operation is impossible. This means that when using the instrument alone, it is impossible to independently and easily adjust the clamping force gradually, or to unlock and remove the instrument from the user's body with one hand. Given the shortcomings of the aforementioned solution, there are significant limitations in practical application, greatly affecting the user experience, making further improvements essential. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems and deficiencies, and to provide a clamping massage device with stepless fine adjustment and locking. This massage device adopts a pistol-style operating mechanism design, which can realize adjustment and unlocking operations with a single hand. Moreover, the adjustment achieved is stepless and finely progressive without any level limitation, which can effectively help people adjust to the most comfortable and secure clamping force.

[0004] The technical solution of this invention is implemented as follows: A clamp-type massager with stepless fine adjustment and locking includes a connecting rod and two massage mechanisms mounted on both ends of the connecting rod and arranged opposite each other; one of the massage mechanisms includes a housing with an inner cavity, a handle, a lever handle, and a massage head disposed on the housing; characterized in that it further includes a friction lever, a friction locking component, two return springs, and a return button; the friction lever and the friction locking component are sequentially arranged and installed in the inner cavity, and the connecting rod passes through the inner cavity and sequentially sleeves with the friction lever and the friction locking component. The components are connected together; two return springs are respectively sleeved on the connecting rod and installed in the inner cavity, one return spring abutting against the friction actuating component and the other return spring abutting against the friction locking component, so that the friction locking component is kept in an inclined state to lock one of the massage mechanisms to the connecting rod; the handle is hinged to the housing, and its inner end is connected to the friction actuating component; the reset button is installed on the housing, and its inner end abutting against the friction locking component. When the reset button is pressed, the return spring pressing against the friction locking component retracts, and the friction locking component returns to the upright unlocked state.

[0005] Furthermore, the inner cavity is also provided with a lever, which consists of a shaft portion, an upper actuating portion, and a lower actuating portion. The shaft portion is sleeved on a pin provided in the inner cavity. The upper actuating portion abuts against a friction actuating component and a friction locking component. The lower actuating portion abuts against abutting part and a reset button provided on the actuating handle.

[0006] Furthermore, another massage mechanism includes a fixed base, a locking screw, a screw hole, and a massage head. The fixed base is provided with a rod hole and a transverse locking hole. The rod hole is fitted with a connecting rod. The locking screw passes through the transverse locking hole and is locked into the screw hole, so that the connecting rod and the fixed base are assembled together.

[0007] The beneficial effects of this invention are as follows: By employing a pistol-style operating mechanism and incorporating a friction lever, a friction locking element, a return spring, and a reset button within the mechanism, the invention functions much like shooting a pistol. Repeatedly pressing and moving the lever allows one massage mechanism to move continuously along the connecting rod towards another, thus reducing the clamping space between the two massage mechanisms to achieve a suitable clamping force. When the massage device needs to be removed from the body, pressing the reset button simultaneously moves one of the massage mechanisms, allowing it to easily move in the opposite direction along the connecting rod, thereby increasing the clamping space between the two massage mechanisms. Adjustment and unlocking can be performed with a single hand, and the adjustment is stepless and progressively fine, effectively helping users find the most comfortable and secure clamping force.

[0015] like Figures 1 to 4 As shown, the clamping massager with stepless fine adjustment and locking according to the present invention includes a connecting rod 1 and two massage mechanisms 2 installed on both ends of the connecting rod 1 and arranged opposite to each other. To achieve the objectives proposed in this invention, one of the massage mechanisms 2 of this massage instrument includes a housing 3 with an inner cavity 31, a handle 4, a toggle handle 5, a friction actuating element 6, a friction locking element 7, a return spring 8, a return button 9, and a massage head 10. The friction actuating element 6 and the friction locking element 7 are sequentially arranged and installed in the inner cavity 31. The connecting rod 1 passes through the inner cavity 31 and is sequentially sleeved with the friction actuating element 6 and the friction locking element 7. The return spring 8 is installed in the inner cavity and abuts against the friction actuating element 6 and the friction locking element 7, respectively, so that the friction locking element 7 locks one of the massage mechanisms 2 onto the connecting rod 1. The handle 4 is hinged to the housing 3, and its inner end is connected to the friction actuating element 6. The return button 9 is installed on the housing 3, and its inner end abuts against the friction locking element 7. The massage head 10 is disposed on the housing 3. Another massage mechanism 2 of this invention can also be designed with the same function and structure as the aforementioned massage mechanism 2, or it can be designed differently. In this embodiment, as... Figure 1 and Figure 2As shown, the other massage mechanism 2 is a simplified version, lacking a pistol-style operating mechanism. Its specific structure includes a fixed base 30, a locking screw 40, a screw hole 50, and a massage head 10. The fixed base 30 has a rod hole 301 and a transverse locking hole 302. The rod hole 301 is fitted onto the connecting rod 1. The locking screw 40 passes through the transverse locking hole 302 and locks into the screw hole 50, thus assembling the connecting rod 1 and the fixed base 30 together. To prevent axial swinging around the connecting rod 1 and to ensure a more secure installation, as shown... Figure 2 As shown, a limiting pin 102 is also provided on the connecting rod 1, and a corresponding notch 303 is provided in the rod hole 301. By using the limiting pin 102 and the notch 303 to fit together, the fixed seat 30 can be prevented from swinging around the connecting rod axially. The screw hole 50 can be provided on the connecting rod 1 or on the fixed seat 30. In this embodiment, the screw hole 50 is provided on the connecting rod 1 as an example.

[0016] To prevent the friction actuating component 6 and the friction locking component 7 from interfering with each other during movement, such as Figure 3 and Figure 4 As shown, two return springs 8 are installed in the inner cavity 31. These two return springs 8 are respectively sleeved on the connecting rod 2. One return spring 8 abuts against the friction actuating member 6, and the other return spring 8 abuts against the friction locking member 7. Through holes for the connecting rod 1 to pass through are also provided on the friction actuating member 6 and the friction locking member 7. Furthermore, to ensure that the friction actuating member 6, the friction locking member 7, and the return springs 8 can be stably installed in the inner cavity 31 and can move in a set direction, such as... Figure 3 and Figure 4 As shown, the inner cavity 31 is also provided with a plurality of protruding parts 311 for limiting the friction actuating part 6, the friction locking part 7, and the return spring 8. By using the limitation of the protruding parts 311, the friction actuating part 6, the friction locking part 7, and the return spring 8 are stably and safely installed in the inner cavity 31.

[0017] like Figure 3 and Figure 4As shown, a lever 20 is also provided in the inner cavity 31. The lever 20 consists of a shaft portion 201, an upper actuating portion 202, and a lower actuating portion 203. The shaft portion 201 is fitted onto a pin 312 provided in the inner cavity 31. Two levers 20 are respectively provided in the inner cavity 31. The upper actuating portion 202 of one lever 20 abuts against the friction actuating member 6, and the lower actuating portion 203 of the other lever 20 abuts against the abutting portion 51 provided on the lever handle 5. The upper actuating portion 202 of the other lever 20 abuts against the friction locking member 7, and the lower actuating portion 203 of the other lever 20 abuts against the reset button 9. By using this lever 20, the present invention utilizes the lever-saving principle, making it easier and smoother for the human finger to actuate the lever handle 5 and press the reset button 9.

[0018] To facilitate the manufacture of the housing 3 and the installation of the aforementioned components within the cavity 31 of the housing 3, such as... Figure 3 As shown, the housing 3 includes a front cover plate 32 and a bottom shell 33, which are fixedly assembled together by screws 100.

[0019] To allow for a larger clamping space between the two massage heads 10, such as Figure 1 and Figure 2 As shown, the bottom shell 33 is also provided with an extension portion 34, which is provided with a through hole 341 and a locking bolt 342. The massage head 10 is provided with a fitting rod portion 101, which is fitted into the through hole 341 and locked by the locking bolt 342. Correspondingly, the fixed base 30 is also provided with an extension portion 34, which is provided with a through hole 341 and a locking bolt 342. The massage head 10 is provided with a fitting rod portion 101, which is fitted into the through hole 341 and locked by the locking bolt 342.

[0020] The extension 34 can be designed as a straight strip shape, an arc shape, or other shapes that match the body shape of the human body.

[0021] like Figure 8As shown, the massage head 10 can be composed of a human body contact part 103, a connecting post 104, a plug-in seat 105, a power rod 106, a rotating wheel 107, a micro motor 108, a housing 109, and an end cap 110. The rotation of the micro motor 108 sequentially drives the rotating wheel 107 to rotate, which in turn drives the power rod 106 to perform a reciprocating linear motion. The power rod 106 then drives the plug-in seat 105 to perform a reciprocating linear motion. The connecting post 104 is plugged into the plug-in seat 105, and the human body contact part 103 is connected to the connecting post 104. A sleeve rod part 101 is integrally provided at the rear end of the housing 109. A lithium battery 111 is installed inside the sleeve rod part 101, which is connected to the micro motor 108 to provide power. A power switch 112 and a charging interface 113 are also provided at the tail of the sleeve rod part 101. In addition to the aforementioned methods, the massage head 10 can also use an ultrasonic transducer or an ultrasonic vibration motor as the power source for massage. The human body contact part 103 is also provided with a spray hole 114 and a medicine supply tube connection port 115. The medicine supply tube connection port 115 can be connected to an electric medicine supply mechanism, which pumps liquid medicine or liquid medicine gas into the human body contact part 103 and sprays it onto the human skin through the spray hole 114, realizing the combination of medicine and massage in traditional Chinese medicine treatment.

[0022] The working principle of this invention is roughly as follows: In use, grip the handle 4 with one hand and press or move the handle 5 with your fingers, as shown... Figure 5 As shown, pressing the handle 5 moves the friction actuating element 6, which in turn drives the massage mechanism 2 to move along the connecting rod 1. Pressing the handle 5 once moves the massage mechanism 2 along the connecting rod 1 towards another massage mechanism 2 by one movement, i.e. Figure 6 As shown, the return spring 8 simultaneously resets the friction actuating element 6 and the actuating handle 5. Just like firing a pistol, repeatedly pressing the actuating handle 5 allows the massage mechanism 2 to move continuously along the connecting rod 1 towards another massage mechanism 2, thereby reducing the clamping space between the two massage mechanisms 2 and achieving a suitable clamping force. During this process, the friction locking element 7 remains in a constant state... Figures 4 to 6 The tilted state allows the moved position to be locked in time.

[0023] When it is time to remove the massage device from the body, press the reset button 9. This will cause the reset spring 8, which is pressing against the friction locking element 7, to retract, and the friction locking element 7 will return to its upright, unlocked state. Figure 7 As shown; at this time, by moving one of the massage mechanisms 2 synchronously, the massage mechanism 2 can easily move in the opposite direction along the connecting rod 1, thereby realizing the expansion of the clamping space between the massage mechanism 2 and the other massage mechanism 2.
