Description

Fascia rifle drive mechanism

Technical Field

The utility model relates to the field of health care equipment, in particular to a fascia gun transmission mechanism.

Background

The fascia gun is mainly used for relaxing human body large muscle groups and fascia through the vibration massage principle, so that the ache feeling of the human body after sports is reduced, professional athletes and amateur fitness people can use the fascia gun, and the sports training can be more effective. At present, the transmission mechanism of the fascia gun mostly adopts eccentric wheel transmission to drive a crank connecting rod mechanism to convert the rotary motion output by a motor into linear reciprocating motion, so that muscles of a human body are vertically hit, longitudinal deep impact is generated, the massage function is single, the noise is high, and the user experience feeling is not good.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a fascia gun transmission mechanism which is used for performing rotary pressing on sensitive parts or muscles of a human body, is soft in action and low in noise, and improves the use experience of a user.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a fascia gun transmission mechanism comprises a motor, an eccentric shaft, a bearing assembly and a massage head, wherein the motor is a power source of the transmission mechanism and is fixedly arranged in a fascia gun shell; the lower end of the eccentric shaft is fixed on a motor shaft, and the upper end of the eccentric shaft is fixedly connected with a bearing assembly; the bearing assembly comprises a bearing, a bearing pressing plate and a connecting sleeve, the bearing is sleeved at the upper end of the eccentric shaft, the bearing pressing plate fixes the bearing and is fixedly connected with the upper end of the eccentric shaft through a screw, and the connecting sleeve is in threaded connection with the massage head.

The lower end of the eccentric shaft is provided with a hole which can be effectively and fixedly connected with a motor shaft; the upper end of the eccentric shaft is provided with a threaded hole which is fixedly connected with the bearing pressing plate through a screw.

The bearing pressure plate is arranged at the lower part of the bearing assembly and comprises an upper part and a lower part, and the bearing outer ring is fixed through a screw without limiting the rotation of the bearing inner ring; the bearing pressure plate is fixed with the upper end of the eccentric shaft through a screw.

Wherein, the connecting sleeve is sleeved on the upper part of the bearing component, is internally provided with a threaded hole and is connected with the massage head through threads.

Wherein, the massage head connecting shaft is provided with a thread.

The working principle of the utility model is as follows:

1. the motor works, and the motor shaft rotates;

2. the motor shaft drives the eccentric shaft to rotate, and the upper end of the eccentric shaft is parallel to the motor shaft and is not on the same straight line, so that the upper end of the eccentric shaft performs eccentric motion, and the motion amplitude is determined by the distance between the third shafts;

3. the upper end of the eccentric shaft drives the bearing inner ring to do eccentric motion, the eccentric motion is transmitted to the bearing outer ring through the bearing balls, and the bearing outer ring drives the connecting sleeve through the bearing pressing plate to do transverse eccentric vibration;

4. the connecting sleeve drives the massage head to do transverse vibration massage.

Compared with the prior art, the utility model has the advantages that: through the motion conversion of motor shaft, eccentric shaft and bearing assembly, convert the circular rotation of motor shaft into horizontal arc vibration, changed the massage mode that current drive mechanism hit perpendicularly, the action is soft, the noise is little, improves the user and uses the experience and feels, has improved the competitiveness of product.

Drawings

FIG. 1 is an assembly schematic of the present invention;

in the figure: the massage machine comprises a motor 1, a motor shaft 12, an eccentric shaft 2, a bearing 31, a bearing pressing plate 32, a connecting sleeve 33, a screw 34, a screw 35 and a massage head 4.

Detailed Description

The following examples are intended to illustrate the utility model and its uses, but are not intended to limit the scope of the utility model.

Referring to fig. 1, the fascia gun transmission mechanism of the utility model comprises a motor 1, an eccentric shaft 2, a bearing assembly and a massage head 4, wherein the motor is a power source of the transmission mechanism and is fixedly arranged in a fascia gun shell; the lower end of the eccentric shaft is fixed on the motor shaft 12, and the upper end of the eccentric shaft is connected with the bearing assembly 3; the bearing assembly comprises a bearing 31, a bearing pressing plate 32 and a connecting sleeve 33, the bearing is sleeved at the upper end of the eccentric shaft, the upper part and the lower part of the bearing pressing plate fix the bearing through screws 34, and are fixedly connected with the upper end of the eccentric shaft through screws 35, and the connecting sleeve is in threaded connection with the massage head.

The utility model relates to a fascia gun transmission mechanism, which is characterized in that: after the motor 1 is electrified, the motor shaft 12 circularly rotates, the motor shaft drives the eccentric shaft 2 to work, the upper end of the eccentric shaft drives the inner ring of the bearing 31 to do eccentric motion, the bearing balls transmit the eccentric motion of the inner ring to the outer ring of the bearing, the outer ring of the bearing drives the connecting sleeve 33 through the bearing pressing plate 32 to do horizontal eccentric vibration, and therefore the massage head 4 connected with the outer ring of the bearing is driven to complete vibration massage on a human body.
