Embodiment 1

[0034] refer to Figure 1 to Figure 5 , a self-aligning orbital impact massage movement, including a core frame 1, a motor 2, an oblique shaft 21, a swing block 3, a universal shaft joint 4, a connecting rod 5, an impact shaft 6 and an impact bushing 61; the motor 2 and The impact shaft sleeve 61 is correspondingly fixed on the two ends of the core frame 1, and the impact shaft 6 is movably installed in the impact shaft sleeve 61, and one end extending out of the impact shaft sleeve 61 is used for positioning the massage head, and the rear end is hinged with the connecting rod 5; The mandrel 21 is locked on the output shaft of the motor 2 for rotational movement; the swing block 3 is fixed on the inclined mandrel 21 through the bearing 7, and the shaft protrusion 31 on the swing block 3 is connected with the cardan shaft joint 4 through the bearing 7, The universal shaft joint 4 is hinged with the connecting rod 5, which converts the rotational power of the motor 2 into the fo...

Embodiment 2

[0041] refer to Figure 6 and Figure 7 , the overall structure is the same as the previous example, except that the self-aligning rod 81 is inserted and fixed in the radial direction of the impact shaft 6, and the groove frame 821 is integrally formed on the front part of the core frame 1, which improves the rigidity and reduces the amount of assembly; the rail seat A pair of sliding cores 823 in 822 is a cylindrical structure, and the centerline is parallel to the centerline of the impact axis 6; in fact, the aligning rod 81 is only in tangential contact with the sliding cores 823, which is close to linear contact, reducing resistance and noise.

[0042] In accordance with the structure of this embodiment, there are two connecting rods 5, one end is symmetrically clamped on the rear end of the impact shaft 6, and hinged by the hinge shaft 51, and the other end is symmetrically clamped on both sides of the universal joint 4, and hinged on the universal joint 4. On the trunni...

Embodiment 3

[0044] refer to Figure 8 and Figure 9 , the overall transmission relationship is the same as the previous two examples, except that the self-aligning rod 81 is inserted and fixed on the universal joint 4. Since the universal joint is a part with a large swing range, the groove frame 821 is designed as a circular arc structure. The rear end is directly inserted into the horizontal positioning hole 12 formed on the core frame, and the front end is locked on the longitudinal screw column 13 of the core frame by screws; the rail seat 822 and a pair of sliding cores 823 embedded in the rail seat are both formed The arc shape coincides with the groove frame 821, and the cross section of the sliding core 823 is a circular structure, which also reduces the contact surface with the self-aligning Xibaipo 81; The axial hole 42 protruding through and the self-aligning rod 81 inserted therein, and symmetrical trunnions 41 are arranged on both sides. One end of the connecting rod 5 is h...

Abstract

The invention relates to a self-aligning rail type impact massage machine core which comprises a core frame, a motor, an inclined mandrel, a swing block, a universal coupling, a connecting rod, an impact shaft and an impact shaft sleeve. The motor and the impact shaft sleeve are correspondingly fixed to the two ends of the core frame, and the motor drives the inclined mandrel to rotate and drives the impact shaft to do reciprocating rectilinear motion along the impact shaft sleeve through the swing block, the universal shaft joint and the connecting rod. Wherein a guide mechanism is further arranged, and the guide mechanism comprises a self-aligning rod and a track groove; the aligning rod is locked on a non-rotating moving part in the impact shaft transmission chain; the rail groove is formed in the core frame and restrains the movement direction of the aligning rod. According to the invention, the self-aligning rod is matched with the track groove, so that the reciprocating motion of the impact shaft is restrained, the motion flexibility of each part is ensured, unnecessary wear is reduced, and the difficulty of processing and assembling is solved. The whole device has the advantages of being compact in structure, flexible in movement matching, low in noise and free of twisting.

Description

Technical field: [0001] The invention belongs to the field of massage equipment, and in particular relates to a self-aligning track-type impact massage movement, especially a transmission scheme for converting the rotational motion of a motor into a reciprocating linear motion. Background technique: [0002] The existing fascia gun is evolved from the traditional eccentric massage hammer. The transmission scheme is that the motor drives the eccentric shaft on the eccentric wheel to rotate, directly or indirectly driving the reciprocating movement of the impact shaft constrained at one end; the direct drive scheme has a compact structure, but The impact shaft is in a swinging reciprocating motion; indirect drive, that is, the eccentric shaft passes through a connecting rod, and then indexes the impact shaft, so that the impact shaft reciprocates in a straight line in the sleeve; for this reason, through the indirect drive of the connecting rod become the current mainstream so...
