Description

Rotating structure of fascia gun

Technical field

The invention belongs to the technical field of a fascia gun, and specifically relates to a rotation structure of a fascia gun.

Background technique

Fascia gun, also called deep myofascial impact instrument, massage gun. It is a device for deep relaxation of myofascial membrane. It is suitable for physical massage after exercise and fitness. It can reduce muscle stiffness and soreness, relieve muscle fatigue, accelerate blood circulation, and achieve the purpose of improving the health of body soft tissues. However, the prior art fascia gun generally has a fixed connection between the handle and the hammer body, and cannot rotate the angle. The user needs to change the position of the handle when using it to achieve the hammering gun head aligning with the part that needs to be relaxed, which is inconvenient for storage; At that time, because of its fixed structural shape, the space cannot be used flexibly.

Summary of the invention

Aiming at the drawback that the handle of the fascia gun and the hammer body cannot be rotated freely in the prior art, the present invention provides a rotating structure of the fascia gun, which can make the handle and the body rotate mutually, so that the user can use and store More convenient.

The objective of the present invention is achieved by the following technical solutions: a fascia gun rotating structure, including a handle and a casing, the casing is fixedly provided with a clamping disc, and a circular through hole is arranged in the clamping disc, The circular through hole is evenly provided with a number of clamping grooves around the center; the handle is provided with a mounting hole, the mounting hole is provided with a lock, and the handle is provided so that the lock can only be along the center line of the mounting hole A limit guide mechanism that moves back and forth in a direction, the lock includes a base set toward the outside of the mounting hole, and a center position of the base is fixedly connected with a sleeve that is sleeved in the circular through hole and can rotate in the circular through hole A central column, the end of the central column is fixedly connected with a fixed block protruding outward relative to the side of the central column, the fixed block and the base are respectively located on both sides of the clamping plate, and the outer side of the central column is evenly fixed and distributed with at least two and The clamping block matched with the clamping slot has a space between the clamping block and the base; between the lock catch and the clamping plate is provided a spring capable of driving the lock catch to reset and allowing the clamping block to be embedded in the clamping slot .

In the above solution, a lock is provided between the casing and the handle to achieve a rotational connection. The clamping block on the lock buckle cooperates with the clamping groove of the clamping plate to play a limiting role. When the clamping block is embedded in the clamping groove, the casing cannot rotate. When the base of the lock buckle is applied facing the casing When the external force is high, the lock buckle moves to the inside of the casing, the clamping block is separated from the clamping groove, and the spring installed between the base and the clamping plate is compressed, and the casing and the handle can be relatively rotated at this time. When turning to a certain position, you only need to release the external force exerted on the base. The elastic force of the spring will automatically return the lock to the original position. The clamping block is re-inserted into the clamping slot, and the chuck is clamped by the block. It is stuck and cannot be rotated, and thus the fixed case cannot be rotated. The setting of the fixed block can ensure that the displacement of the lock catch will not exceed the initial position of the lock catch when the lock catch is rebounded by the spring. The minimum angle fixed after the casing is rotated is the angle between the adjacent clamping grooves.

Preferably, the position-limiting guide mechanism includes a connecting column with a circular ring structure fixedly arranged on the handle, and a plurality of guide grooves evenly distributed around the center line of the connecting column are fixed on the inner side of the connecting column, and the base is fixed A number of guide blocks matched with the guide grooves are provided. The guide mechanism ensures that the lock can only move back and forth along the center line of the mounting hole on the handle, and also limits the stroke that the lock can be pressed into the housing by external force and restricts the lock from rotating.

Preferably, the outer surface of the connecting column is fixedly connected with two symmetrically arranged connecting ears, and the connecting ears are provided with connecting holes for installing the connecting column on the handle.

Preferably, the clamping plate is symmetrically provided with two fixing holes for installing the clamping plate on the casing.

Preferably, a limiting member with a circular arc structure is fixed on both sides of the circular through hole on the clamping plate, and the center line of the limiting member coincides with the center line of the circular through hole, and the limiting member It is arranged on the side of the chuck plate facing the casing, and the ends of the two limiting members correspond to each other, and the two fixing holes are respectively located between the two ends of the two limiting members; the casing is fixedly connected with Two limit mounting posts respectively matched with the two fixing holes, the end of the limit piece is attached to the limit mounting post, and the clamping plate is provided with a screw that penetrates the fixing hole and is screwed to the limit mounting post screw. The limit piece on the clamping plate and the limit mounting post on the casing can cooperate to limit the rotation of the clamping plate installed on the casing.

Preferably, a spring fixing block for installing a spring is fixed on the base. There are two spring fixing blocks, the two spring fixing blocks are symmetrically arranged around the center line of the base, and one end of the spring is arranged between the two spring fixing blocks. , The other end of the spring rests on the chuck plate. The setting of the spring can make the lock buckle automatically rebound and reset to the initial state after being pressed in, and enable the clamping block that is separated from the clamping groove to be embedded into the clamping groove.

Preferably, the central column has a circular ring structure, the outer end of the central column is provided with grooves penetrating both sides of the central column, there are two fixing blocks, and the two fixing blocks are respectively arranged on both sides of the groove. The groove on the circular center column can cause the fixed block to be forced to drive the center column to produce a certain deformation, and it is convenient for the center column to be installed into the clamping plate.

Compared with the prior art, the present invention has the following beneficial effects: the casing can be used after being rotated to a certain angle, which is convenient for users to use at different angles; when the casing is rotated to an angle parallel to the handle, the ribs can be reduced. The membrane gun occupies a volume, which is easy to carry and store.
