Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0026] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] As shown in Figures 1 to 4 The utility model provides a height adjustable waist rest, including: base 1 and waist support 2, the base 1 is larger than the waist support 2, the base 1 does not provide the basis for the mounting of the waist support 2, and the upper surface area of the waist rest can be expanded, and the expansion of the support area can make the waist rest more comfortable when using, the back of the waist support 2 is provided with a connecting piece 3, the connecting piece 3 can be integrally formed with the waist support 2, or can be fixedly connected through heat melting or other connecting mode, or be connected on the internal thread blind hole on the back of the waist support 2 through screw thread, the waist support 2 is detachably mounted on the base 1 through the connecting piece 3, the base 1 is movably provided with a limiting piece 4, the limiting piece 4 is movably connected with the connecting piece 3, and the limiting piece 4 is used for limiting the connecting piece 3 at different heights relative to the base 1.

[0028] The height-adjustable waist support provided by the utility model: the waist support is limited at different heights by the limiting piece to meet the use requirements of users with different lumbar curvature; meanwhile, the user can adjust the height of the waist support to meet the advanced use requirements after the waist adapts to the current height.

[0029] Further improvement is that a connecting hole 11 is arranged in the middle of the base 1, the connecting piece 3 is inserted into the connecting hole 11, and the limiting piece 4 is movably arranged at the port of the lower surface of the base 1 of the connecting hole 11 and connected with the connecting piece 3 passing through the connecting hole 11. The depth of the connecting piece 3 inserted into the connecting hole 11 is limited by the limiting piece 4, thereby realizing the height adjustment of the waist support 2.

[0030] Further improvement is that the bottom end of the connecting hole 11 is provided with a downward extension 5. The extension 5 provides a mounting position for the limiting piece 4. The extension 5 can be designed integrally with the base 1.

[0031] As shown in Figure 3 , Figure 4 In another embodiment, the extension 5 can also be a separate component, which is cylindrical and has a T-shaped appearance, that is, the top end has a transversely extending step structure to prevent it from falling out of the connecting hole 11, to reduce the manufacturing cost and facilitate installation.

[0032] Meanwhile, the extension 5 has a gap between the outer wall of the cylindrical structure and the connecting hole 11, which will cause shaking during use. In order to avoid this shaking, a limiting clamping hole is arranged at the upper port of the connecting hole 11, and the step structure at the top end of the extension 5 is provided with a downward extending limiting protrusion. During installation, the limiting protrusion is clamped into the limiting clamping hole, thereby preventing the extension 5 from shaking and causing instability of the waist support during use.

[0033] Further improvement is that a pair of opposite fixing holes are arranged on the extension 5, which are the mounting holes of the limiting piece 4. The limiting piece 4 is inserted into the fixing hole. The limiting piece 4 in this embodiment is a strip, preferably made of metal. At least two through limiting holes are arranged on the connecting piece 3 along the central axis direction. Each limiting hole corresponds to a different height of the waist support. The limiting piece 4 is clamped in the fixing hole and the limiting hole. During use, the waist support is adjusted to the required height, the limiting hole and the fixing hole are aligned, the limiting piece 4 is inserted from one side of the fixing hole and then inserted into the other side of the fixing hole through the limiting hole, thereby realizing the fixation of the waist support. This height adjustment method is limited by the number of limiting holes for different height adjustment, and the adjustment accuracy is limited by the distance between the limiting holes.

[0034] As shown in Figure 5 ,Figure 6 In another embodiment, in order to achieve infinite adjustment of the height of the lumbar support 2, the further improvement of the technical solution is that the extension part 5 and the limiting part 4 are connected by the first clamping part 6 and the second clamping part 7 which extend in opposite directions and are clamped together, and the limiting part 4 can rotate axially. That is, if the first clamping part 6 is arranged on the extension part 5, then the second clamping part 7 is arranged on the limiting part 4; if the first clamping part 6 is arranged on the limiting part 4, then the second clamping part is arranged on the extension part 5. By clamping together, the limiting part 4 can rotate axially freely without falling off.

[0035] Further improvement is that the first clamping part 6 extends radially outward on the outer wall of the extension part 5, the second clamping part 7 extends radially inward on the inner wall or port of the limiting part 4, the top surface of the first clamping part 6 supports the bottom surface of the second clamping part 7, and the first clamping part 6 is used to limit the second clamping part 7 between the first clamping part 6 and the lower surface of the base 1.

[0036] Further improvement is that the connecting part 3 is provided with external threads, the limiting part 4 is provided with internal threads, and the limiting part 4 is threadedly connected with the connecting part 3 which is exposed on the extension part 5 after passing through the connecting hole. By rotating the limiting part 4, the depth of the connecting part 3 inserted into the connecting hole can be adjusted, and then the height of the lumbar support is adjusted.

[0037] In order to make the whole lumbar support more beautiful, the further improvement of the technical solution is that a recess 12 is formed in the middle of the upper surface of the base 1, and the lumbar support 2 is embedded in the recess 12. The inner wall of the recess 12 also plays a guiding role in the lifting of the lumbar support 2, and also shows that the lumbar support 2 is shaking, improving the use experience. In order to avoid the rotation of the lumbar support 2 with the rotation of the limiting part 4, the recess 12 is formed into a non-circular shape in this embodiment. In order to improve the comfort, the lumbar support 2 in the technical solution is preferably longer than wide, and the two ends are arc-shaped.

[0038] If the recess 12 is circular, a corresponding anti-rotation structure needs to be arranged on the outer periphery of the lumbar support 2 and the inner wall of the recess 12, for example, a vertical protruding part is arranged on the outer wall of the lumbar support 2, and a corresponding recess is formed at the corresponding position of the inner wall of the recess 12, and the two are clamped together during installation, thereby achieving anti-rotation.

[0039] In order to further improve the massage effect of the lumbar support, the further improvement of the technical solution is that a plurality of protrusions 8 are arranged on the upper surface of the lumbar support 2. The protrusions can be dot matrix protrusions, or a plurality of continuous or discontinuous strip-shaped protrusions.

[0040] In order to further improve the comfort, the further improvement of the technical solution is that the waist support 2 is covered with an elastic layer on at least the upper surface. The elastic layer can be pasted on the upper surface of the waist support 2, and the upper surface of the base 1 except the groove 12 can also be covered with an elastic layer. The material of the elastic layer can be plastic, rubber, silica gel, foam and other materials with elasticity.

[0041] In order to make the base 1 further fit the waist of the user, the two sides of the base 1 in the length direction are upwardly curved, and the two sides in the width direction have downward inclined surfaces.

[0042] The further improvement is that, in order to avoid the separate protrusion on the back of the base 1 affecting the use of the waist rest, the back of the base 1 is provided with a receiving groove 9 for receiving the limiting member 4, so that the limiting member 4 and the connecting member 3 do not protrude from the receiving groove 9.

[0043] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
