At this time, it is necessary to continuously adjust the height, which is a more cumbersome process, reducing the user experience and the convenience of the device. For this reason, the applicant proposes a height-adjustable exercise brick. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] As people's living standards continue to improve, exercise bricks are needed in many sports and fitness. Because each person's physique is different, the height of the exercise bricks needs to be adjusted to achieve the effect of exercise and fitness. Therefore, a height-adjustable exercise brick is needed. In the actual use process, most traditional height-adjustable exercise bricks can only complete the height adjustment by continuously stacking the exercise bricks. However, the height of the exercise bricks of the device itself is unchanged, so it cannot be well adjusted to a height that some users can be satisfied with. At the same time, the device also occupies more space during storage, which reduces the convenience of the device and the user's experience. For this reason, the applicant proposes a height-adjustable exercise brick.
[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a height-adjustable exercise brick, comprising an exercise brick chassis 1, an adjustment mechanism 2 is fixed on the top of the exercise brick chassis 1, the adjustment mechanism 2 comprises a fixed frame 201, notches are respectively opened on both sides of the outer wall of the fixed frame 201, telescopic sleeves 202 are respectively fixed at the top and bottom frame openings of the fixed frame 201, a fixing ring 203 is fixed at the top center of the inner wall of the top telescopic sleeve 202, a sliding sealing pad 204 is slidably connected to the inner wall of the fixing ring 203, a fixing rod 205 is fixed at the top center of the sliding sealing pad 204, and the notches on both sides of the outer wall of the fixed frame 201 are fixed. The two telescopic sleeves 202 are respectively fixed with expansion pipes 206, and the two telescopic soft frames 207 are respectively fixed on both sides of the outer wall of the two telescopic sleeves 202. A stable soft frame 208 is fixed between the two telescopic soft frames 207. One end of the two brackets of the stable soft frame 208 is fixed to one side of the fixed frame 201, and the expansion pipe 206 is located inside the stable soft frame 208. The two sides of the top of the exercise brick chassis 1 are respectively fixed with a stabilizing mechanism 3, and the top of the stabilizing mechanism 3 is fixed to the two sides of the bottom of the adjusting mechanism 2. One side of the two stable soft frames 208 is respectively provided with openings, and the notches on both sides of the inner wall of the fixed frame 201 and the openings on one side of the inner wall of the two stable soft frames 208 are respectively provided with openings. A fixed tube 209 is fixed separately, and a rotating sealing plate 210 is connected to the inner wall of the fixed tube 209 on both sides of the rotating sealing plate 210. Torsion springs 211 are fixed between the inner wall of the fixed tube 209 on both sides of the rotating sealing plate 210. A plurality of first springs 212 are fixed between the inner wall of the stable soft frame 208 and the outer wall of the fixed frame 201. The flaring tube 206 is located between the plurality of first springs 212. A pressing plate 213 is fixed to one side of the outer wall of the telescopic soft frame 207. A pressing frame 214 is fixed to one side of the adjacent pressing plates 213. A fixed plate 215 is fixed to the top of the outer wall of the top telescopic sleeve 202. The fixed plate 215 A soft pad 216 is fixed on the top, and a pressing cap 217 is fixed on the top of the fixing rod 205 after the top end passes through the telescopic sleeve 202, the fixing plate 215 and the soft pad 216 respectively. A second spring 218 is fixed between the bottom of the pressing cap 217 and the top of the fixing plate 215. The cross-sectional area of the pressing cap 217 is equal to the through hole area of the soft pad 216. The inner wall area of the tube opening at one end of the expanded tube 206 is smaller than the inner wall area of the tube opening at the other end, and the smaller inner wall area of the tube opening at the end is equal to the inner wall area of the notch of the outer wall of the fixed frame 201. The longitudinal cross-sectional area of the rotating sealing plate 210 is larger than the notch area of the fixed frame 201.
[0024] It should be noted that: when adjusting the height of the device, by pressing the pressing frames 214 on both sides of the adjusting mechanism 2, the pressing frames 214 will transfer the pressure to the two groups of pressure plates 213, and the two groups of pressure plates 213 will transfer the pressure to the two groups of telescopic soft frames 207. At this time, the air inside the telescopic soft frames 207 will form pressure on the rotating sealing plate 210 inside the fixed tube 209 through the expanding tube 206. At the same time, the first spring 212 contracts. Because the air inlet end of the expanding tube 206 is larger than the exhaust end of the expanding tube 206, the wind pressure at the exhaust end is greater than the wind pressure at the air inlet end, which can make the rotating sealing plate 210 rotate well. When the air is squeezed into the two telescopic sleeves 202, the height of the telescopic sleeves 202 is increased. When the height is too high, because the longitudinal cross-sectional area of the rotating sealing plate 210 is larger than the notch area of the fixed frame 201, the rotating sealing plate 210 will be reset under the action of the torsion spring 211, and one side of the rotating sealing plate 210 will contact one side of the inner wall of the fixed frame 201. Subsequently, the first spring 212 will be reset, so that the stable soft frame 208 drives the two telescopic soft frames 207 to expand. At this time, the external air will enter the two telescopic soft frames 207 through the opening of the stable soft frame 208. When the height of the device is too high, it is only necessary to press the pressing cap 217 to shrink the second spring 218. After the sliding sealing pad 204 slides out of the fixed ring 203, the air inside the telescopic sleeve 202 can be discharged in a controllable manner.
[0025] like Figure 5 As shown, the utility model provides a technical solution: a height-adjustable exercise brick, including a stabilizing mechanism 3, the stabilizing mechanism 3 includes two groups of stabilizing frames 301, a plurality of telescopic rods 302 are fixed to opposite surfaces of each group of stabilizing frames 301, a fixing block 303 is fixed between adjacent telescopic rods 302, a fixing sleeve 304 is fixed to the outer wall of the fixing block 303, a connecting rod 305 is fixed between each group of adjacent fixing sleeves 304, the top and bottom of the two groups of stabilizing frames 301 are respectively fixed to the two sides of the bottom of the adjusting mechanism 2 and the two sides of the top of the exercise brick chassis 1, and the sum of the maximum heights of each group of telescopic rods 302 is greater than or equal to the maximum height of the adjusting mechanism 2.
[0026] It should be noted that when the device is in use, as the adjustment mechanism 2 changes, the telescopic rod 302 will also change, thereby increasing the stability of the device. The interaction between the fixing sleeve 304 and the connecting rod 305 can improve the stability between the two sets of fixing blocks 303.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
