Description

Technical Field

[0001] This invention relates to the field of posture correction devices, and more particularly to a universal adjustment mechanism for a chest support spring. Background Technology

[0002] Incorrect reading and writing posture and viewing at too close a distance are the main causes of myopia. Incorrect sitting posture can easily lead to myopia and spinal deformities, which affect physical health. This mostly occurs during the period of rapid physical growth in primary and secondary schools, and teenagers and students will unconsciously develop the habit of incorrect sitting posture.

[0003] There are various posture correctors on the market to help teenagers, students, office workers, and other users correct their sitting posture. These correctors generally include a base, a fixing block, and a chest support. When in use, the rigid chest support is fixed to the fixing block, and the surface of the chest support fits against the user's chest. However, because the contours of the user's chest are not uniform, after long-term use, the hard contact between the surface of the chest support and the chest can cause discomfort and a hard feeling in the user's chest, and the fit is not stable. When the body moves slightly, the chest will also slide relative to the chest support for a large range, and the chest will detach from the chest support, making it difficult for the chest to fit against the chest support. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a universal adjustment mechanism for a chest support spring to solve the problem that the chest of the human body is not stable in contact with the chest support plate when the human body moves slightly.

[0005] To achieve the above objectives, the basic solution of the present invention is as follows: a universal adjustment mechanism for a chest support spring, comprising a base plate and a chest support housing that can be connected to a fixing block, the base plate being detachably mounted on one side of the chest support housing, and further comprising a plurality of chest support plates and a plurality of universal adjustment units mounted between the base plate and a single chest support plate, the universal adjustment unit comprising a connecting rod, a spherical shell, and a spherical rotating head, the rotating head being fitted inside the spherical shell, the outer wall of the rotating head being in sliding contact with the inner wall of the spherical shell, the spherical shell being provided with a rotating opening, one end of the connecting rod passing through the rotating opening and being fixedly connected to the rotating head, and the other end of the connecting rod being fixedly connected to one side of the chest support plate; the spherical shell being fixedly connected to the base plate.

[0006] The technical principle of this invention is as follows: When installing the universal adjustment mechanism for the chest support spring, the mechanism is installed on the fixed block, and the chest support plate is positioned opposite the chest of the human body. When using the universal adjustment mechanism for the chest support spring, the chest support plate can automatically adjust according to the contour of the human chest. The chest support plate drives the rotating head to rotate relative to the spherical shell through the connecting rod, and the angle of the chest support plate is effectively adjusted, so that the chest support plate effectively conforms to the contour of the human chest, allowing different people to use the chest support plate with a corresponding degree of fit.

[0007] Simultaneously, when the chest of the human body moves relative to the chest support plate, the chest of the human body is in contact with the chest support plate. At this time, the chest support plate will change direction accordingly under the change of the supporting force. The chest support plate will also drive the rotating head to move relative to the spherical shell through the connecting rod, which can also realize the multi-angle adjustment of the chest support plate. Through the cooperation of the spherical shell and the rotating head, a stable support can be provided for the chest support plate, while also providing flexible directional adjustment of the chest support plate.

[0008] Furthermore, the connecting rod is hollow inside, and the side of the chest support plate is provided with a plug that can be inserted into the connecting rod. The plug and the connecting rod are detachably connected.

[0009] With the above settings, when connecting the chest support plate and the universal adjustment unit, the insert rod on the chest support plate can be inserted into the connecting rod, enabling quick and stable installation of the connecting rod and the chest support plate, and making the installation of the chest support plate and the connecting rod more convenient.

[0010] Furthermore, the spherical shell is hemispherical in shape, the rotating opening is located at the center of the spherical shell, the rotating head is a hollow hemispherical shape, and the connecting rod is fixedly connected to the center of the rotating head; the base plate is provided with an installation opening with the same diameter as the spherical shell, and the end face of the spherical shell is fixedly connected to the installation opening of the base plate.

[0011] With the above configuration, both the spherical shell and the rotating head are hemispherical, which fully controls the rotation range of the rotating head while reducing the space occupied by the spherical shell and the rotating head, making the installation between the spherical shell and the rotating head and the base plate more compact; at the same time, the hollow design of the rotating head can reduce the weight of the rotating head, making the universal adjustment unit lighter.

[0012] Furthermore, it also includes a spring, with one end of the connecting rod near the rotating head located inside the rotating head, one end of the spring sleeved outside the end of the connecting rod located in the rotating head and abutting against the inner wall of the rotating head, and the other end of the spring abutting against the inner wall of the chest support housing.

[0013] When pressure is applied to the chest support plate by the user's chest, the pressure is transmitted to the spring through the chest support plate, insert rod, connecting rod and rotating head, compressing the spring. During this process, the chest support plate will change position according to the contour of the user's chest, making the chest support plate more flexible. When not in use, the chest support plate will quickly return to its original position under the action of the spring.

[0014] Furthermore, it also includes a first limiting cylinder, the inner diameter of which is the same as the inner diameter of the spherical shell. One end of the first limiting cylinder is fixedly connected to the end face of the spherical shell. The first limiting cylinder is located between the bottom plate and the inner wall of the chest support shell, and a sliding gap is provided between the end of the first limiting cylinder away from the spherical shell and the inner wall of the chest support shell.

[0015] With the above settings, the first limiting cylinder can limit the rotation of the rotating head. When the spring is compressed, it can also control the rotating head and the spring to be within the range of the first limiting cylinder, so that when not in use, the rotating head and the spring can return to their original positions and prevent the rotating head and the spring from detaching from the spherical shell.

[0016] Furthermore, it also includes a second limiting cylinder, which is fixedly installed on the inner wall of the chest support housing. The second limiting cylinder is coaxially arranged with the first limiting cylinder, and the end of the spring near the chest support housing is coaxially arranged inside the second limiting cylinder.

[0017] With the above configuration, the second limiting cylinder can further restrict the end of the spring that is close to the chest support housing, so that the spring is limited between the second limiting cylinder and the rotating head, which facilitates the transmission of pressure to the spring and keeps the spring supporting the rotating head.

[0018] Furthermore, a bending gap is provided between the end of the second limiting cylinder away from the chest support housing and the end of the connecting rod located inside the rotating head.

[0019] With the above configuration, when the rotating head rotates relative to the spherical shell, the spring at the gap can bend slightly, so that the freedom of the chest support plate is not restricted by the second limiting cylinder and the connecting rod.

[0020] Furthermore, the spring is in contact with the outer wall of the connecting rod and the inner wall of the second limiting cylinder.

[0021] With the above settings, the spring can be stably installed on the connecting rod and the second limiting cylinder, making the spring's support for the rotating head more stable, and the spring can also more easily restore its elasticity.

[0022] Furthermore, there are two chest support plates, which are symmetrically arranged along the center line of the base plate surface, and both the chest support plates and the base plate surface are curved.

[0023] By designing the curved surface of the chest support board, the corresponding curve is more adapted to the contour of the human chest, making it easier for the surface of the chest support board to fit better against the human chest.

[0024] Furthermore, a silicone layer can be detachably installed on the chest support plate.

[0025] Through the above design, the silicone layer provides a soft and comfortable feel to the human chest area, and also allows the human chest area to fit snugly against the silicone layer and the breast support board. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] The implementation examples are basically as follows Figure 1 Appendix Figure 2 and attached Figure 3 As shown, this embodiment of the invention proposes a universal adjustment mechanism for a breast support spring, including a base plate 10, a spring 40, a first limiting cylinder 401, a second limiting cylinder 402, a breast support housing 20 that can be snapped together with a fixing block, two breast support plates 30, and two universal adjustment units installed between the base plate 10 and a single breast support plate 30. The lower surface of the base plate 10 is provided with eight inserts 101, which are evenly distributed at the edge of the lower surface of the base plate 10. The breast support housing 20 is provided with eight slots 201 for inserting the inserts 101, and the inserts 101 correspond one-to-one with the slots 201.

[0035] like Figure 2As shown, the universal adjustment unit includes a connecting rod 501, a spherical shell 502, and a spherical rotating head 503. The rotating head 503 is fitted inside the spherical shell 502 and is a hollow hemispherical shape. The outer wall of the rotating head 503 is in sliding contact with the inner wall of the spherical shell 502. The spherical shell 502 has a rotating opening located at its center. The lower end of the connecting rod 501 passes through the rotating opening and engages with the rotating head 503. The center is integrally formed, and the lower end of the connecting rod 501 is located inside the rotating head 503. The other end of the connecting rod 501 is fixedly connected to one side of the chest support plate 30. The base plate 10 is provided with an installation opening with the same diameter as the spherical shell 502. The end face of the spherical shell 502 is integrally formed with the installation opening of the base plate 10. At the same time, the connecting rod 501 is hollow inside, and the side of the chest support plate 30 is provided with an insert rod 504 that can be embedded in the connecting rod 501. The insert rod 504 is inserted into the connecting rod 501.

[0036] like Figure 2 As shown, the inner diameter of the first limiting cylinder 401 is the same as the inner diameter of the spherical shell 502. One end of the first limiting cylinder 401 is fixedly connected to the end face of the spherical shell 502. The first limiting cylinder 401 is located between the base plate 10 and the inner wall of the chest support shell 20, and a sliding gap is provided between the lower end of the first limiting cylinder 401 and the inner wall of the chest support shell 20. The upper end of the spring 40 is sleeved outside the lower end of the connecting rod 501 and abuts against the inner wall of the rotating head 503. The lower end abuts against the inner wall of the chest support housing 20; the second limiting cylinder 402 is integrally formed on the inner wall of the chest support housing 20, the second limiting cylinder 402 is coaxially arranged with the first limiting cylinder 401, the lower end of the spring 40 is coaxially arranged inside the second limiting cylinder 402, a bending gap is provided between the upper end of the second limiting cylinder 402 and the lower end of the connecting rod 501, the spring 40 is in contact with the outer wall of the connecting rod 501, and the spring 40 is in contact with the inner wall of the second limiting cylinder 402.

[0037] like Figure 1 As shown, there are two chest support plates 30, which are symmetrically arranged along the center line of the surface of the base plate 10, and both the surface of the chest support plate 30 and the surface of the base plate 10 are curved; as Figure 3 As shown, a silicone layer 50 is detachably installed on the chest support plate 30.

[0038] In this embodiment, the universal adjustment mechanism for the chest support spring is installed by first installing the chest support housing 20 and the base plate 10, aligning the lower surface of the base plate 10 with the upper surface of the chest support housing 20, and then pressing down on the base plate 10 and the chest support housing 20 so that the insert block 101 is inserted into the corresponding slot 201, thereby achieving a snap-fit ​​between the chest support housing 20 and the base plate 10; then, the insert rod 504 on a single chest support plate 30 is inserted into the connecting rod 501, thereby achieving the insertion of the insert rod 504 and the connecting rod 501, and connecting the chest support plate 30 to the base plate 10; finally, the entire universal adjustment mechanism for the chest support spring is snap-fitted onto the fixing block so that the chest of the human body is opposite the chest support plate 30.

[0039] When the chest support uses the spring-loaded universal adjustment mechanism, the chest support plate 30 is positioned opposite and in close contact with the chest of the user. The chest of the user contacts the silicone layer 50 on the chest support plate 30, providing a soft and comfortable feel. This allows the chest to conform to the silicone layer 50 and the chest support plate 30, maintaining a constant distance between the chest and the desk, and keeping the spine upright. This helps correct and control the user's posture. When adjusting their posture, the chest of the user presses against the chest support plate 30 at any angle. The silicone layer 50 and the chest support plate 30, in contact with the chest, control the rotation of the insertion rod 504, connecting rod 501, and rotating head 503. The rotating head 503 rotates within the spherical shell 502, allowing the chest support plate 30 to rotate relative to the bottom. During the rotation of plate 10, the chest support plate 30 remains in contact with the chest of the human body. At the same time, the chest of the human body presses on the chest support plate 30. This pressure is transmitted to the spring 40 through the chest support plate 30, the insert rod 504, the connecting rod 501, and the rotating head 503. The spring 40 is stably compressed under the limitation of the second limiting cylinder 402. When the pressure decreases, the spring 40 can automatically rebound, realizing the reset of the chest support plate 30, the insert rod 504, the connecting rod 501, and the rotating head 503. During this process, since there is a sliding gap between the lower end of the first limiting cylinder 401 and the inner wall of the chest support shell 20, and a bending gap between the upper end of the second limiting cylinder 402 and the lower end of the connecting rod 501, the rotation of the chest support plate 30 and the compression of the spring 40 can be carried out synchronously. The chest support plate 30 can rotate relative to the base plate 10 or rotate relative to the base plate 10.

[0040] During use, the spherical shell 502 and the rotating head 503 work together to form a universal joint structure, giving the chest support plate 30 freedom of movement and rotation. Under the reaction force applied by the spring 40, the position changes according to the contour of the user's chest. The chest support plate 30 and the silicone layer 50 can always keep in close contact with the chest of the human body. When the chest of the human body moves slightly, the chest support plate 30 can also move and rotate synchronously, so that the chest support plate 30 is fully in contact with the chest of the human body, and the chest of the human body will not feel a strong pressure.

[0041] Example 2

[0042] The difference between Example 2 and Example 1 is that Example 2 also includes the basic components shown in the appendix. Figure 4 and attached Figure 5 The rebound unit and temperature control unit shown are shown. The rebound unit includes several hemispherical protrusions 60. The protrusions 60 are glued to the upper surface of the base plate 10, and the protrusions 60 surround the edge of the base plate 10. The protrusions 60 are supported by elastic rubber and can abut against the lower surface of the chest support plate 30.

[0043] As attached Figure 5 As shown, the temperature control unit includes a rechargeable battery 70, a heating wire 80 wound on the chest support plate 30, a first switch 801 controlling the heating wire 80 to turn on or off, a cooling wire 90 wound on the chest support plate 30, a miniature refrigeration compressor 901 connected to the cooling wire 90, and a second switch 902 controlling the miniature refrigeration compressor 901 to turn on or off. The battery 70 and the miniature refrigeration compressor 901 are both snapped into the chest support housing 20. The first switch 801 and the second switch 902 are both fixed to the outer wall of the chest support housing 20 by bolts. The first switch 801 and the heating wire 80 are connected in series and electrically connected to the battery 70. The second switch 902 and the miniature refrigeration compressor 901 are connected in series and electrically connected to the battery 70.

[0044] When the universal adjustment mechanism of the chest support spring in Embodiment 2 is in use, when the chest support plate 30 rotates too much relative to the base plate 10, the lower surface of the chest support plate 30 can abut against the flexible protrusion 60, so that the chest support plate 30 is buffered from rotation; when the chest of the human body no longer abuts against the chest support plate 30, the flexible protrusion 60 can also rebound, so that the chest support plate 30 returns to its original position. The flexible protrusion 60 can cooperate with the spring 40, so that the chest support plate 30 quickly returns to its original position.

[0045] Meanwhile, when using the universal adjustment mechanism of the breast support spring in winter, pressing the first switch 801 can turn on the heating wire 80, which heats the breast support plate 30 and the silicone layer 50, keeping them warm to the touch and enhancing comfort. When using the universal adjustment mechanism of the breast support spring in summer, when the weather is hot, the chest area may feel stuffy due to the continuous contact between the breast support plate 30 and the silicone layer 50. In this case, pressing the second switch 902 will activate the micro... The refrigeration compressor 901, a miniature refrigeration compressor 901, can cool the cooling wire 90. The cooling wire 90 exchanges heat with the chest support plate 30 and the silicone layer 50, thereby cooling the chest area and keeping it cool. When heating or cooling is not needed, the first switch 801 or the second switch 902 can be turned off. When the power in the battery 70 is depleted, the battery 70 can be recharged, improving the overall performance of the chest support spring universal adjustment mechanism.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
