Summary of the invention

[0003] The utility model aims to provide a body correction device, the correction stick of which can be rotated and switched between an unfolded state and a folded state.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A body correction device, characterized in that it includes a connecting seat and four correction rods, one end of at least one correction rod is rotatably connected to the connecting seat, the correction rod can be rotated between an unfolded state and a folded state, and the four correction rods in the unfolded state form a cross structure, so that at least one correction rod can be converted between the unfolded state and the folded state.

[0006] The four correction rods are all rotatably connected to the connecting seat. The four correction rods in the folded state are close to each other, so that the four correction rods in the unfolded state form a cross structure. The four correction rods in the folded state are close to each other, which can reduce the storage space.

[0007] The utility model also comprises a locking member, which limits the rotation of the correction rod and keeps the correction rod in the unfolded state.

[0008] The rotation axis of the correction rod is perpendicular to the central axis of the cross-shaped structure, and the rotation axes of two adjacent correction rods are arranged vertically, so that the correction rods only need to rotate ninety degrees from the unfolded state to the folded state to achieve the close folding of the four correction rods.

[0009] A positioning notch is provided at one end of the correction rod connected to the connecting seat, and the locking member includes a positioning portion. When the correction rod is in the unfolded state, the positioning portion can be moved into the positioning notch to limit the rotation of the correction rod, or the positioning portion is disengaged from the positioning notch to allow the correction rod to rotate.

[0010] The locking member includes four positioning parts arranged circumferentially, and the locking member can be rotatably arranged on the connecting seat around the arrangement center of the positioning parts. The rotation of the locking member causes the four positioning parts to move into the positioning notch or to disengage from the positioning notch. In this way, four correction rods can be simultaneously restricted to remain in the unfolded state or in the foldable state through one locking member, thereby facilitating the switching of the body correction device between the unfolded state and the folded state.

[0011] The positioning part is formed with a limiting surface inclined along its moving direction, and the limiting surface can be rotated to be in close contact with the positioning notch. The inclined limiting surface can make it easier for the positioning part to enter the positioning notch and make the limiting surface in close contact with the positioning notch, so that the correction rod can be kept in the expanded state without shaking.

[0012] The connecting seat includes four adapter parts arranged in a circle, and the adapter parts include two parallel and spaced opposite support plates. The correction rod is rotatably supported between the two support plates through a pivot axis, so that the correction rod can rotate along a certain trajectory when converting between the unfolded state and the folded state without misalignment or shaking.

[0013] The connecting seat has a front end surface for the correction rod in the unfolded state to abut against, the correction rod includes a rod body and a connecting piece, the connecting piece is fixedly arranged at one end of the rod body, the connecting piece has a connecting portion located between the two support plates, the connecting portion is rotatably supported between the two support plates through the pivot axis, the positioning notch is formed on the connecting portion, the positioning notch and the rod body are located on both sides of the pivot axis and the positioning notch faces the front end surface of the connecting seat, the positioning portion can be moved between the front end surface and the positioning notch to limit the rotation of the rod body toward one side, and the front end surface can limit the rotation of the correction rod toward the opposite other side.

[0014] The connecting seat includes a circular end plate, an annular side plate and the adapter portion, the annular side plate is connected to the circumference of the circular end plate, and four adapter portions are arranged circumferentially on the front end surface of the circular end plate, so that the structure of the connecting seat can be more reasonable and compact.

[0015] The circular end plate is formed with an elongated notch extending from the rear to the support plate, and the elongated notch forms an elongated hole on the support plate for the pivot shaft to pass through, which facilitates injection molding of the elongated hole without the need for additional processing of the elongated hole.

[0016] The circular end plate is formed with an avoidance notch that extends from the rear to the support plate. The avoidance notch forms an avoidance opening on the support plate for avoiding the positioning portion. The width of the positioning portion is smaller than the distance between the two support plates, which facilitates the injection molding of the avoidance opening without additional machining of the avoidance opening. The avoidance opening can also prevent the locking member from detaching from the connection seat.

[0017] It further includes a abutting member which is movably and adjustably arranged on the connection seat along the central axis of the cross-shaped structure. The abutting member is used to abut against the user's back, and the adjustable abutting member can adapt to users of different body sizes.

[0018] The abutting member includes an abutting portion and an adjusting rod. The abutting portion is connected to the adjusting rod. A spiral groove is formed on the outer peripheral surface of the adjusting rod. The connection seat is formed with a mounting hole for the adjusting rod to pass through, and a spiral protrusion that mates with the spiral groove is formed on the inner wall of the mounting hole. In this way, by rotating the abutting member, the abutting portion can be moved back and forth for adjustment, and the operation is very convenient and fast.

[0019] The abutting member has an arc-shaped abutting surface, which can better fit the user's back, thus increasing the comfort of the product during use.

[0020] The connection seat is formed with an annular side plate, and the abutting member is formed with an annular guiding cylinder that is sleeved with the annular side plate, which can make the rotation of the abutting member more stable, and the supporting strength of the abutting member is better and it will not shake.

[0021] The locking member is rotatably sleeved on one end of the adjusting rod, so that there is no need to separately set the rotating shaft of the locking member, which reduces costs and facilitates the assembly of the product.

[0022] The connection seat is provided with a limiting portion that restricts the correction rod from rotating towards one side to be positioned in the unfolded state. For example, when the correction device in the unfolded state abuts against the back side of the human body during use, the limiting portion can restrict the relative left and right correction rods from rotating towards the body side, and restrict the upper and lower correction rods from rotating away from the body side. In this way, relying on the action of the arm, the left and right correction rods can be kept in the unfolded state, and relying on the abutment on the back side of the human body, the upper and lower correction rods can be kept in the unfolded state.

[0032] Reference Figures 1 to 8 As shown, a body correction device includes a connecting seat 2, four correction rods 1, a locking member 4 and a supporting member 3.

[0033] The connecting seat 2 includes a circular end plate 21, an annular side plate 22 and four adapter parts 23. The annular side plate 22 is connected to the circumference of the circular end plate 21. The four adapter parts 23 are circumferentially arranged on the front end surface of the circular end plate 21. The circular end plate 21, the annular side plate 22 and the four adapter parts 23 are integrally injection molded. The adapter part 23 includes two parallel and spaced opposite support plates 231. The support plates 231 of two adjacent adapter parts 23 are interconnected to form an L-shaped structure, which can improve the strength of the support plate 231. The rear end surface of the circular end plate 21 is formed with criss-crossing reinforcing ribs 27, and the reinforcing ribs 27 are used to improve the strength of the circular end plate 21.

[0034] The abutting member 3 includes an abutting portion 311, an adjusting rod 32, and an annular guiding cylinder 312. The adjusting rod 32 is tightly connected to the middle of the back surface of the abutting portion 311 through a screw 34. The abutting portion 311 is formed with a counterbore for the screw 34 to pass through, and a cover 35 is provided on the counterbore. The annular guiding cylinder 312 is connected to the back surface of the abutting portion 311 and is coaxially arranged with the adjusting rod 32. The annular guiding sleeve 312 is integrally formed with the abutting portion 311. A spiral groove 321 is formed on the outer peripheral surface of the adjusting rod 32. An installation tube 26 for the adjusting rod 32 to pass through is formed at the central position of the connecting seat 2. The installation tube 26 is axially penetrated to form an installation hole 261, and a spiral protrusion 262 matching the spiral groove 321 is formed on the inner wall of the installation hole 261. In this way, the abutting portion 311 can be moved back and forth for adjustment by rotating the abutting member 3, and the operation is very convenient and fast. An arc-shaped abutting surface a is formed on the front surface of the abutting portion 311, and the arc-shaped abutting surface a is used to abut against the back of the user. The position of the adjustable arc-shaped abutting surface a can adapt to users of different body sizes. The annular guiding cylinder 312 and the annular side plate 22 are sleeved with each other, which can make the rotation of the abutting member 3 more stable, and the supporting strength of the abutting member 3 is better and there is no shaking.

[0035] An elastic buffer layer 33 is provided on the arc-shaped abutting surface a. The elastic buffer layer 33 is snap-connected to the abutting portion 311. A plurality of fastening holes 3111 are formed on the arc-shaped abutting surface a, and a fastening portion 331 matching the fastening holes 3111 is formed on the elastic buffer layer 33. The elastic buffer layer 33 can better adapt to the back of the user, so that the comfort of the product can be increased during use.

[0036] The circular end plate 21 is formed with an elongated notch 24 extending from the back to the support plate 231. The elongated notch 24 forms an elongated hole 241 on the support plate 231 for the pivot shaft 133 to pass through. This can facilitate the injection molding of the elongated hole 241 without additional machining of the elongated hole. Similarly, the circular end plate 21 is formed with an avoidance notch 25 extending from the back to the support plate 231. The avoidance notch 25 forms an avoidance opening 251 on the support plate 231 for avoiding the positioning portion 42. This can facilitate the injection molding of the avoidance opening 251 without additional machining of the avoidance opening 251. The avoidance opening 251 can also limit the locking member 4 from detaching from the connecting seat 2.

[0037] The correction stick 1 includes a stick body and a connecting piece 13. The stick body includes a metal tube body 11 and a buffer sleeve 12 sleeved on the outside of the metal tube body 11. The buffer sleeve 12 is made of elastic materials such as foam. The connecting piece 13 includes a sleeve 131 and a connecting portion 132. The sleeve 131 and the connecting portion 132 are integrally injection molded. The sleeve 131 is fixedly sleeved on one end of the metal tube body 11. A plug 14 is provided at the other end of the metal tube body 11. The inner wall of the sleeve 131 is formed with a plurality of convex strips extending along its length direction and arranged circumferentially, which can increase the plug-in firmness between the sleeve 131 and the metal tube body 11. The connecting portion 132 can be rotatably supported by a pivot shaft 133. Between the two support plates 231, the correction rod 1 can be rotated between the unfolded state and the folded state. The four correction rods 1 in the unfolded state form a cross structure, and the four correction rods 1 in the folded state are close to each other. The locking piece 4 is arranged on the connecting seat 2 to limit the rotation of the correction rod 1 so that the correction rod 1 remains in the unfolded state. The four correction rods 1 in the folded state are close to each other, which can reduce the storage space. The rotation axis of the correction rod 1 is perpendicular to the central axis of the cross structure, and the rotation axes of two adjacent correction rods 1 are arranged vertically. In this way, the correction rod 1 only needs to be rotated ninety degrees from the unfolded state to the folded state to achieve the close folding of the four correction rods 1.

[0038] The four correction rods 1 in the unfolded state are in the same plane. This structure is more ergonomic and has a better correction effect. Of course, they can also be in different planes to achieve the effect of body correction.

[0039] Specifically, the pivot shaft 133 is a tube body with an axial notch, and the connecting portion 132 is formed with a through hole for the pivot shaft 133 to pass through. The pivot shaft 133 is inserted into the through hole and has an interference fit with the through hole, so that the two ends of the pivot shaft 133 protrude from both sides of the connecting portion 132 and extend into the elongated holes 241 of the two support plates 231, thereby realizing the rotational connection between the correction rod 1 and the adapter 23.

[0040] The correction rod 1 in the expanded state can abut against the front end face of the circular end plate 21 of the connecting seat 2. Specifically, the connecting seat 2 is formed with a rest groove 211 adapted to the connecting piece 13. The connecting piece 13 of the correction rod 1 in the expanded state abuts against the rest groove 211 to limit the correction rod 1 from swinging toward one side. The connecting part 132 is formed with a positioning notch 1321. The positioning notch 1321 and the rod body are located on both sides of the pivot shaft 133 and the positioning notch 1321 faces the front end face of the circular end plate 21 of the connecting seat 2.

[0041] The front section of the adjusting rod 32 of the abutting member 3 passes through the front end face of the connecting seat 2. The locking member 4 includes an operating tube 41 and four positioning portions 42. The operating tube 41 is rotatably sleeved on the front section of the adjusting rod 32. The four positioning portions 42 are arranged in a circumferential array on the outer peripheral surface of one end of the operating tube 41. The other end of the operating tube 41 is closed and formed with an operating portion 43. The operating portion 43 is a plate-like structure, which is convenient for rotating the operating tube 41. Anti-slip lines 411 can also be formed on the outer peripheral surface of the other end of the operating tube 41 to increase the friction for rotating the operating tube 41. The locking member 4 can rotate between a first position and a second position. When the locking member 4 is in the first position, the positioning portion 42 moves to between the front end face of the circular end plate 21 and the positioning notch 1321 to limit the correction rod 1 from rotating towards one side. The circular end plate 21 can limit the correction rod 1 from rotating towards the opposite side. When the locking member 4 is in the second position, the positioning portion 42 moves into the avoidance opening 251. The avoidance opening 251 simultaneously limits the locking member 4 from detaching from the connecting seat 2. The positioning portion 42 is formed with a limiting surface 421 inclined along its moving direction. The limiting surface 421 can be rotated to be in close contact with the positioning notch 1321. The inclined limiting surface 421 can make the positioning portion 42 more easily enter the positioning notch 1321 and make the limiting surface 421 in close contact with the positioning notch 1321, so that the correction rod 1 is kept in the unfolded state without shaking. In addition to the above structure, the locking member 4 can also use a bolt as the locking member, and the correction rod 1 is locked in the unfolded state by the bolt.

[0042] During assembly, the operating tube 41 of the locking member 4 is sleeved on the front section of the adjusting rod 32. At the same time, the four positioning portions 42 are inserted between the two support plates 231, and rotated by a certain angle to make the positioning portions 42 move into the avoidance opening 251. Then, the connecting portion 132 of the connecting member 13 and the two support plates 231 are rotatably connected through the pivot shaft 133. In this way, the assembly of the locking member 4 and the correction rod 1 can be completed. In this way, four correction rods 1 can be simultaneously restricted to be kept in the unfolded state or in the foldable state by one locking member 4, so as to facilitate the switching of the body correction device between the unfolded state and the folded state.

[0043] During use, the correction rod 1 is rotated to the unfolded state, and the four correction rods 1 form a cross-shaped structure. Then, the locking member 4 is rotated to make the positioning portion 42 closely cooperate with the positioning notch 1321, so as to limit the rotation of the correction rod 1. When storage is required, the locking member 4 is rotated to make the positioning portion 42 move into the avoidance opening 251, so that the positioning portion 42 is disengaged from the positioning notch 1321. At this time, the correction rod 1 can be rotated to make the four correction rods 1 rotate to the folded state where they are close to each other.

[0044] The above is only the preferred embodiment of the present invention, and thus cannot limit the scope of implementation of the present invention. That is, the equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the specification should still fall within the scope covered by the patent of the present invention.
