[0026] like Figures 1 to 4 As shown, an adjustable height table frame includes a frame 1, suitable for supporting and adjusting objects such as tabletops. It addresses the limitations of existing table frames that are functionally limited and inconvenient to use. Each frame has both a fixed part 21 and a movable part 22. A first crossbeam 11 is provided between adjacent fixed parts 21, and a second crossbeam 12 is provided between adjacent movable parts 22. A first sleeve 13 is connected to the first crossbeam 11, and a movable component 14, movably inserted into the first sleeve 13, is connected to the second crossbeam 12. A positioning part 141 is provided on the side wall of the movable component 14. The sleeve 13 has a vertically arranged movable elongated hole 131 on its side wall. Multiple positioning holes 132 are arranged on the side of the movable elongated hole 131. Each positioning hole 132 is connected to the movable elongated hole 131. The positioning part 141 can slide along the movable elongated hole 131 as the movable part 22 rises to lock into any positioning hole 132. A movable rod 4 for connecting the panel and allowing it to be unfolded upwards to adjust the angle is hinged to one end of the support rod 3. The support member 5 is also included, with one end rotatably connected to the movable rod 4 and the other end detachably and fixedly connected to the support rod 3, which can realize the fixing of the panel at different angles.

[0027] In this embodiment, the table frame is mainly composed of a frame body 1, which consists of four telescopic legs 2. These four telescopic legs 2 are located at the four corners of the table frame, forming a stable rectangular frame. Each telescopic leg 2 is divided into a fixed part 21 and a movable part 22. The movable part 22 can move up and down within the fixed part 21, thereby achieving height adjustment. To enhance the stability and adjustment function of the structure, a first crossbeam 11 is provided between the fixed parts 21 on adjacent sides of any two parallel planes to fix and connect the fixed parts 21 on both sides. A first sleeve 13 is connected to the first crossbeam 11. The first sleeve 13 has a movable cavity inside, with the opening facing upward. Correspondingly, a second crossbeam 12 is provided between the movable parts 22 on the corresponding sides. A downwardly positioned movable member 14 is connected to the second crossbeam 12. The movable member 14 is rectangular and is movably inserted into the movable cavity. When the movable part 22 moves up and down relative to the fixed part 21, the movable member 14 also moves up and down within the movable cavity. The width of the movable part 14 is slightly narrower than the movable cavity, allowing it to move vertically and also to some extent horizontally. Furthermore, vertically extending movable elongated holes 131 are provided on both sides of the first sleeve 13, and positioning protrusions 141, movable along the elongated holes, are provided on the corresponding sides of the movable part 14. Multiple positioning holes 132 of different heights are arranged on one side of the movable elongated hole 131, all of which communicate with the movable elongated hole 131. The cross-section of each positioning hole 132 is semi-heart-shaped, with an arc-shaped surface between adjacent positioning holes 132, and each positioning hole 132 has a hook groove at its bottom, facilitating the positioning part 141 to slide into the positioning hole 132 and lock in place when moving along the movable elongated hole 131, preventing sinking after lifting.

[0028] Two parallel support rods 3 are provided, with their ends fixed to the tops of the two telescopic legs 2 on the adjacent sides. A hinge or universal joint is provided at one end of each support rod 3 to hinge a movable rod 4. The two movable rods 4 are fixed to the bottom sides of the panel, allowing the panel to be unfolded and adjusted to a suitable angle relative to the hinged ends of the support rods 3. To ensure the panel's stability at different angles, a support member 5 is also provided. One end of the support member 5 is rotatably connected to the movable rod 4, allowing it to be unfolded or folded relative to the movable rod 4, while the other end is detachably fixed to the support rods 3. Thus, when the panel is unfolded and adjusted to the desired angle, the support member 5 provides additional support, ensuring the panel's stability at different angles. The support can also be a gas spring or a hinge bracket, with one end of the gas spring or hinge bracket connected by a hinge (such as...). The hinge or ball joint pin is fixed to the bottom of the two movable rods, and the other end is fixed to the top of the two support rods by a hinge connector. Both are used to... The elastic or telescopic properties support the movable rod and the tabletop fixed to it, allowing it to open to a suitable angle and enabling it to... It is stably fixed at that angle.

[0029] like Figure 3 As shown, in this embodiment, the support rod 3 is provided with a plurality of slots 31 arranged at intervals, and the other end of the support member 5 away from the movable rod 4 is engaged into different slots 31. The support structure uses a hinged bracket with movable rods on both sides, and the other side of this bracket... The end can be snapped into each slot, and The design of multiple slots 31 allows the support 5 to be engaged at different positions, thereby achieving panel fixation at multiple angles.

[0030] like Figure 2 As shown, the top of the movable elongated hole 131 in this embodiment has a reset area 133. The positioning part 141 can rise into the reset area 133 and then fall back to the lowest point. The reset area 133 is located at the top of the movable elongated hole 131, and its side does not have a positioning hole 132. When the movable part 14 rises to the reset area 133 along with the movable part 22 of the telescopic leg 2, because there is no positioning hole 132 on its side to lock the positioning part 141, the movable part 14 will automatically fall back to the lowest point, completing the reset.

[0031] like Figure 1 As shown, the fixing part 21 in this embodiment includes a column 211 and a second sleeve 212 fixed to the side wall of the column 211 and parallel to the first sleeve 13. Each movable part 22 is movably inserted into the second sleeve 212. Specifically, the fixing part 21 is composed of four columns 211, with a second sleeve 212 provided inside it, and an upwardly open movable cavity provided inside it, so that the movable part 22 adapted to the movable cavity can slide and rise and fall along the cavity, ensuring that the lifting and lowering adjustment of the table frame is more stable and precise, and reducing shaking and deviation.

[0032] like Figure 3 as well as Figure 4 As shown, in this embodiment, a locking member 6 is rotatably connected to the side wall of the support rod 3. The locking member 6 has a hook groove 61. A stop member 7 adapted to the hook groove is provided at the position of the movable rod 4 corresponding to the locking member 6. After the locking member 6 is rotated, the stop member 7 can be engaged into the hook groove 61. Specifically, a protrusion is fixedly provided on one side of the movable rod 4 as a stop member 7, and a locking member 6 rotatably connected to the support rod 3 is provided at the corresponding position of the support rod 3. A hook groove 61 adapted to the size of the stop member 7 is provided inside the locking member 6. When the panel is not unfolded, simply rotate the locking member 6 to engage the stop member 7 into the hook groove 61 to complete the fixation; conversely, rotating the locking member 6 in the opposite direction will unlock the panel. The operation is simple and quick.

[0033] like Figure 1As shown, the bottom of the frame 1 in this embodiment is also provided with a moving mechanism 8 for driving the table frame to move. The moving mechanism 8 includes a bottom beam 81 fixedly connected to the bottom end of the adjacent telescopic legs 2 and casters 82 located at the bottom ends of the bottom beams 81. Specifically, the moving mechanism 8 in this embodiment consists of two bottom beams 81 and four casters 82. The two bottom beams 81 are parallel to the aforementioned support rod 3 and fixedly connected to the bottom end of the adjacent telescopic legs 2 to increase the stability of the bottom of the table frame. The casters 82 are arranged at both ends of the bottom of the bottom beams 81, allowing the user to easily move the table frame by simply pushing it. In addition, the casters 82 are provided with a locking structure, which can be locked when movement is not required to prevent the table frame from sliding.

[0034] In summary, the beneficial effects of this embodiment are as follows: When the movable part 22 is adjusted to the required height relative to the fixed part 21, the positioning part 141 of the movable bar can be engaged and positioned within the positioning hole 132 in the first sleeve 13, ensuring stability at the adjusted height and preventing accidental sinking. The panel angle can be adjusted by hinged connection of the movable rod 4 to the support rod 3, and the support member 5 can be engaged with the slot 31 on the end face of the support rod 3, ensuring stability of the panel after angle adjustment. A moving mechanism 8, including a bottom beam 81 and casters 82, is provided at the bottom of the frame 1, allowing the table frame to move.

[0035] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
