DETAILED DESCRIPTION

[0027] The utility model is further described in detail below with reference to the accompanying drawings. A child walker with height adjustment function comprises a bottom frame 1 and a panel 2, wherein a plurality of wheels 3 are arranged at the bottom of the bottom frame 1 to support the bottom frame 1 to slide on the ground, and a seating area 21 is provided in the middle of the panel 2: sleeves 4 are extended upwards on both sides of the bottom frame 1, and columns 5 are extended downwards on both sides of the panel 2, and the columns 5 are connected with the sleeves 4 to fix the panel 2 and the bottom frame 1 as a whole; a height adjustment device is also arranged between the columns 5 and the sleeves 4 to adjust the relative height between the panel 2 and the bottom frame 1.

[0028] In one embodiment, the upper end surface of the sleeve 4 is provided with a concave docking hole 41, and correspondingly, the lower end surface of the column 5 is provided with an inserting tube 51 extending downward, and the column 5 is inserted into the docking hole 41 through the inserting tube 51 to be connected thereto.

[0029] In one embodiment, the outer contour of the insert tube 51 is smaller than the outer contour of the column 5 .

[0030] In one embodiment, the height adjustment device is a plurality of vertically distributed lock holes 6 arranged in the sleeve 4. Correspondingly, a lock tongue 7 is arranged on the column 5. The lock tongue 7 is connected to the lock holes 6 at different heights to adjust their height.

[0031] In one embodiment, the locking tongue 7 is connected to a driving mechanism, and the driving mechanism drives the locking tongue 7 to move, thereby achieving docking or separation of the locking tongue 7 and the lock hole 6.

[0032] In one embodiment, the driving mechanism is a linkage plate 8 vertically slidably installed in the column 5, the top of the linkage plate 8 is connected to the push plate 9 arranged outside the column 5, the bottom of the linkage plate 8 is provided with a through hole 81, and a guide hole 82 on the column surface of the column 5, and the lock tongue 7 passes through the through hole 81 and is inserted into the guide hole 82; the lock tongue 7 is provided with a first inclined surface 71 on both sides, the first inclined surface 71 abuts against the second inclined surface 83 located on the linkage plate 8, and a first spring 84 is also provided between the lock tongue 7 and the column 5, and the first spring 84 pushes the first inclined surface 71 of the lock tongue 7 to always press on the second inclined surface 83.

[0033] In one embodiment, the first inclined surface 71 and the second inclined surface 83 are inclined in opposite directions.

[0034] In one embodiment, a second spring 85 is further provided between the linkage plate 8 and the column 5 , and the second spring 85 pushes the linkage plate 8 to always move downward, forcing the second inclined surface 83 to separate from the first inclined surface 71 .

[0035] In one embodiment, a receiving groove 52 is concavely arranged on the cylindrical surface of the column 5, a mounting groove 53 penetrating the column 5 is arranged at the bottom of the receiving groove 52, and a linkage column 91 is arranged at the bottom of the push plate 9 to pass through the mounting groove 53 and connect with the linkage plate 8.

[0036] Working principle: In this case, a height adjustment device is installed between the column 5 and the sleeve 4, which is mainly composed of a plurality of vertically distributed lock holes 6 located inside the sleeve 4 and a lock tongue 7 on the column 5. The lock tongue 7 can be docked with the lock holes 6 of different heights, thereby adjusting the relative height between the panel 2 and the bottom frame 1 to accommodate children of different heights.

[0037] When the height needs to be adjusted, the user presses the push plate 9, and the linkage plate 8 moves upward along the column. Since the second inclined surface 83 on the linkage plate contacts the first inclined surface 71 of the lock tongue 7, the lock tongue is pushed out of the lock hole 6 by mutual compression of the inclined surfaces. With the help of the locking relationship between the column and the sleeve, the user can adjust the height of the panel. When the adjusted height matches, the lock tongue can be reinserted into the lock hole under the push of the first spring.

[0038] The second spring 85 keeps the linkage plate 8 pressed downward all the time, so that the first inclined surface is separated from the second inclined surface, and the first spring always pushes the lock tongue to move toward the lock hole, ensuring that the lock tongue remains in a safe locked state in the lock hole when not operated.

[0039] The receiving groove 52 and the mounting groove 53 provided on the column surface of the column 5 further improve the stability of the structure and also protect the internal mechanism from damage.

[0040] Furthermore: when the user needs to disassemble the walker for storage, the user can unlock the door so that the column and the sleeve are separated, and then the panel and the bottom frame can be separated, and then the two can be stacked together, thereby reducing its idle volume. While making it convenient for users to carry and store, it also correspondingly reduces the packaging volume of the manufacturer, thereby reducing the cost of packaging, transportation, and warehousing, and further reducing the production cost, so it can be widely promoted and used.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the utility model.
