[0002] Massage equipment is an auxiliary tool designed specifically for different parts of the body. It helps relax muscles, relieve pain, promote blood circulation, and relieve stress through physical stimulation. Nowadays, massage devices have developed structures that can massage different parts of the body. However, existing massage devices still have limitations in use. The massage structures of existing massage devices require multiple motors to provide power for each part, which greatly increases costs. At the same time, the massage intensity and amplitude of existing massage structures are relatively small, which affects the comfort of use. Therefore, it is necessary to provide a massage device that can be driven by a single motor, reducing manufacturing costs, while improving user comfort. Utility Model Content
[0003] The present invention provides a reciprocating massage device with a swinging structure, which aims to solve the problem that existing massage devices are not convenient to control the reciprocating swinging massage operation through a single power source.
[0004] To achieve the above objectives, this utility model provides a reciprocating massage device with a swing structure, including a swing reciprocating component;
[0005] The reciprocating oscillating assembly includes a drive motor, the output end of which is connected to a drive shaft. A motor connecting shaft is fitted onto the side surface of the drive shaft. Two eccentric cams are fixedly connected to the side surface of the motor connecting shaft.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 This utility model provides a reciprocating massage device with a swing structure, including a swing reciprocating component 100;
[0022] The oscillating reciprocating assembly 100 includes a drive motor 101, the output end of which is connected to a drive shaft 102. A motor connecting shaft 103 is sleeved on the side surface of the drive shaft 102. Two eccentric cams 104 are fixedly connected to the side surface of the motor connecting shaft 103. A fixing hardware shaft 105 is installed at the upper end of the motor connecting shaft 103. A first oscillating block 106 and a second oscillating block 107 are respectively sleeved on the side surface of the fixing hardware shaft 105. A connecting bracket 108 is installed at the front end of the fixing hardware shaft 105. A reciprocating shaft 109 is connected to the side surface of the motor connecting shaft 103. A fixing cover 110 is installed on the side surface of the connecting shaft 103. A lower cover 120 is installed at the lower end of the fixing cover 110. An upper cover 130 is installed at the front end of the lower cover 120. An arc-shaped shell 140 is fixedly connected to the lower ends of the first swing block 106 and the second swing block 107. An arc-shaped groove 150 is opened at the lower end of the arc-shaped shell 140. The first swing block 106 and the second swing block 107 are both connected inside the arc-shaped groove 150. A circulation groove 170 is opened on the side surface of the reciprocating shaft 109. A limiting shell 160 is sleeved on the side surface of the reciprocating shaft 109. A ball bearing 180 is rolled inside the circulation groove 170.
[0023] In one specific embodiment, the swing reciprocating component 100 can be driven by the same power source, the drive motor 101, to simultaneously achieve two functions: the alternating movement of the first swing block 106 and the second swing block 107, and the reciprocating movement of the upper cover 130 and the lower cover 120. This significantly reduces product manufacturing costs and facilitates widespread use. In use, when the drive motor 101 is started, rotating the drive shaft 102, it drives the two opposing eccentric cams 104 to swing the first swing block 106 and the second swing block 107 up and down, thus achieving the effect of simultaneous left-right swinging of the first swing block 106 and the second swing block 107. The end of the drive shaft 102 has a flat section in the shape of a straight line. When the drive shaft 102 is inserted into the flat section, the reciprocating shaft 109 is fitted into the connecting bracket 108. The connecting bracket 108 has two guide posts. The rotation of the drive shaft 102 can link the reciprocating shaft 109. In conjunction with the circulation groove 170 opened on the surface of the reciprocating shaft 109, the ball bearing 180 is fixed in the upper cover 130 and the lower cover 120. It is fitted into the guide posts of the bracket and the ball bearing 180 is installed in the circulation groove 170 of the reciprocating shaft 109. When the reciprocating shaft 109 rotates, the upper cover 130 and the lower cover 120 can form an up-and-down reciprocating motion effect under the action of the ball bearing 180. This can greatly reduce cost and improve comfort, thereby enhancing the practicality of the massage device.
[0024] Please see Figure 4 The lower cover 120 has a limiting groove 111 inside, and a connecting groove 112 is provided at the end of the limiting groove 111.
[0025] In one specific embodiment, the limiting groove 111, together with the connecting groove 112, can not only limit the installation of the drive motor 101, but also improve the protection effect of the drive motor 101.
[0026] Please see Figure 4 The lower cover 120 has a protective seat 121 installed inside.
[0027] In one specific embodiment, the protective seat 121 can improve the protection performance of the drive motor 101 and extend the service life of the drive motor 101.
[0028] Please see Figure 5 A bearing 131 is fitted onto the side surface of the motor connecting shaft 103.
[0029] In one specific embodiment, the bearing 131 can reduce the friction when the motor connecting shaft 103 rotates, thereby improving the smoothness of the massage device's reciprocating oscillation.
[0030] Please see Figure 5A retaining ring 141 is fitted on the side surface of the reciprocating shaft 109. A spherical groove 142 is provided inside the retaining ring 141, and the ball bearing 180 is tumblingly connected inside the spherical groove 142.
[0031] In one specific embodiment, the retaining ring 141 facilitates the locking and positioning of the ball 180. When the retaining ring 141, in conjunction with the spherical groove 142, squeezes the ball 180, the reciprocating shaft 109 can be controlled to reciprocate.
[0032] Please see Figure 5 Two positioning rods 151 are movably inserted into the side surface of the fixing ring 141, and two positioning grooves 152 are opened on the side surface of the limiting shell 160, with both positioning rods 151 slidably inserted into the inside of the positioning grooves 152.
[0033] In one specific embodiment, the positioning rod 151 is inserted into the positioning groove 152. When the reciprocating shaft 109 reciprocates, the positioning rod 151 can play a positioning role, thereby improving the stability of the massage device.
[0034] Please see Figure 3 The surfaces of the first swing block 106 and the second swing block 107 are both provided with insertion holes 161, and the fixed hardware shaft 105 is inserted into the insertion hole 161.
[0035] In one specific embodiment, the fixed hardware shaft 105 is inserted into the insertion hole 161 to limit the first swing block 106 and the second swing block 107, thereby improving the swing stability of the first swing block 106 and the second swing block 107.
[0036] Working principle: In use, when the drive motor 101 is started, the drive shaft 102 rotates, which in turn drives the two eccentric cams 104, which are set in opposite directions, to swing the first swing block 106 and the second swing block 107 up and down. This achieves the effect of the first swing block 106 and the second swing block 107 swinging left and right in opposite directions at the same time. At the same time, the reciprocating shaft 109 is fitted into the connecting bracket 108, and the connecting bracket 108 has two guide posts. The rotation of the drive shaft 102 can link the reciprocating shaft 109. In conjunction with the circulation groove 170 opened on the surface of the reciprocating shaft 109, the ball bearings 180 on the guide posts of the bracket are installed in the circulation groove 170 of the reciprocating shaft 109. When the reciprocating shaft 109 rotates, the upper cover 130 and the lower cover 120 can form an up and down reciprocating motion effect under the action of the ball bearings 180. This can greatly reduce cost and improve comfort, thereby enhancing the practicality of the massage device.
