Description

Technical Field

[0001] This utility model belongs to the technical field of training tables, and in particular relates to a steel frame for a training table. Background Technology

[0002] With the continuous development of the education and training industry, traditional training tables can no longer meet the needs of modern training in terms of function and design. The steel frame of the training table is its core structural component. In existing training or meeting scenarios, in order to adapt to different spatial layouts and needs, training tables often need to be folded and unfolded. Foldable tables not only facilitate storage but also make full use of indoor space. However, traditional folding tables generally achieve their folding function by hinged joints between the tabletop and legs. However, current folding tables lack a structure to lock the table in both folded and horizontal positions. Therefore, the tabletop still wobbles back and forth when the table is folded or horizontal, affecting its usability. Utility Model Content

[0015] Please see Figure 1-3As shown, this utility model is a training table steel frame, including a table board 4, with a support seat 3 fixed at both ends of the bottom side of the table board 4, and a connecting beam B5 connecting the two support seats 3. Support legs A1 are pivotally connected to the support seats 3, and the two support legs A1 are connected by a connecting beam A101; support legs B2 are pivotally connected to the lower part of the support legs A1.

[0016] Based on the above, the support leg A1, connecting beam A101, support leg B2 and connecting beam B5 are all square tubes. By controlling the rotation of support leg A1 and support leg B2 relative to each other, the included angle between them can be adjusted, thereby adjusting the height of the training table within a certain range.

[0017] Specifically, such as Figure 1 A circular hole A21 is provided on the top side wall of the support leg B2, and a circular hole B that mates with the circular hole A21 is provided on the support leg A1; it also includes a T-shaped pin 23 that passes through the circular hole A21 and the circular hole B in sequence, and the end of the T-shaped pin 23 is provided with a threaded structure, and a ball head nut 22 is threaded onto the threaded structure; multiple positioning holes A20 are provided on the support leg B2 located around the circular hole A21, and a positioning post A11 that is inserted into the positioning hole A20 is provided on the outer wall of the support leg A1; through the cooperation of the T-shaped pin 23 and the positioning hole A20, the support leg B2 can be quickly folded and unfolded, and can be height adjusted and reliably locked, which enhances the portability and adaptability of the table frame.

[0018] like Figure 2-3 To facilitate the connection between the tabletop 4 and the support leg A1 using the support base 3, the provided support base 3 includes a support plate 31 connected to the tabletop 4, with multiple mounting holes 32 on the support plate 31; a mounting plate 30 is provided on one side of the support plate 31, the mounting plate 30 and the support plate 31 are integrally formed and are L-shaped; a reinforcing plate connects the mounting plate 30 and the support plate 31; a rotating post 34 is provided on the side wall of the mounting plate 30, and a rotation hole that mates with the rotating post 34 is provided on the top of the support leg A1. 103, at least one through hole 104 is opened on the support leg A1 located below the rotating hole 103, and a positioning post B14 passes through the through hole 104; one end of the positioning post B14 is connected to the operating plate 13, and the other end passes through the positioning hole B33 provided on the mounting plate 30; there are several positioning holes B33, which are distributed in a ring around the rotating post 34; then, in use, the positioning post B14 and the ring-distributed positioning holes B33 can be used to fix the adjusted support seat 3 in multiple positions.

[0019] To secure the positioning assembly consisting of positioning post B14 and operating plate 13 and prevent it from being pulled out, such as Figure 3-4A rectangular hole 151 is provided on the support leg A1 located below the rotating hole 103; a support block 17 is provided inside the support leg A1, and a sliding block 152 that slides along the inside of the support leg A1 is connected to one side of the support block 17 by a spring 18. An operating block 15 that fits against the outer wall of the support leg A1 is connected to one side of the sliding block 152 by a connecting part that passes through the rectangular hole 151; a limit rod 16 is provided on the sliding block 152, and a limit insertion hole 141 for inserting the limit rod 16 is provided on the positioning post B14. The internal linkage mechanism consisting of the spring, the sliding block, and the operating block facilitates locking and unlocking of the positioning component.

[0020] A perforated baffle 102 is connected between the two support legs A1 located below the connecting beam A101.

[0021] Height adjustment and locking principle: First, loosen the ball head nut at the end of the T-pin so that the head of the T-pin is no longer pressing tightly against the support leg B, thereby releasing the lock on the support leg B. At this time, the operator can rotate support leg A and support leg B relative to each other to change the angle between them. When the angle increases, the overall height of the table frame decreases; when the angle decreases, the overall height of the table frame increases. Support leg B is provided with a series of positioning holes A at different heights. Then, insert the positioning pin A on support leg A into the positioning hole A on support leg B at the required height to achieve initial positioning; Finally, pass the T-pin through the aligned round holes A and B, and tighten the ball head nut to firmly clamp support legs A and B with the tightening force, thus completing the final height locking.

[0022] The principle of tabletop angle adjustment and locking: Push the operating block down, and the operating block will drive the internal sliding block to compress the spring through the connecting part, so that the limit rod on the sliding block will exit from the limit insertion hole of the positioning post B; By controlling the support base, it can rotate freely around its pivot in the rotation hole of the support leg A, thereby causing the table above to change its angle. After adjusting the tabletop to the desired angle, align the other positioning hole B on the support base with the through hole on the support leg A, and insert the positioning pin B through the through hole and into the positioning hole B. When the operating block is released, the sliding block returns to its original position under the action of the spring's restoring force. The limit rod then inserts into the limit socket of the positioning post B, preventing the positioning post B from accidentally coming out, thereby reliably locking the angle of the tabletop.
