[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present invention: a rotary limiting block, including a base 1, a mounting post 2 fixedly connected to the upper surface of the base 1, a limiting disk 3 fixedly connected to the outer wall of the mounting post 2, an arc-shaped plate 4 slidably connected to the inner wall of the limiting disk 3, a connecting rod 5 fixedly connected to one side of the outer wall of the arc-shaped plate 4, the connecting rod 5 slidably connected inside the limiting disk 3, a first telescopic rod 6 fixedly connected to one end of the connecting rod 5, a support base 7 fixedly connected to one end of the first telescopic rod 6, a second telescopic rod 8 fixedly connected to the upper surface of the support base 7, a limiting block 9 fixedly connected to the upper surface of the second telescopic rod 8, an adjusting assembly 10 for adjusting the height of the limiting block 9 installed on the lower surface of the limiting block 9, and a plurality of mounting blocks 20 fixedly connected to the outer wall of the base 1; the adjusting assembly 10 includes a first lead screw 1001 rotatably connected to the lower surface of the limiting block 9, a first knob 1002 threadedly connected to the outer wall of the first lead screw 1001, and the first knob 1002 rotatably connected to the upper surface of the support base 7;
[0023] Specifically, during installation, first firmly fix the installation block 20 at a predetermined usage position to ensure that the entire device can be stably supported. Next, the operator holds and rotates the first knob 1002, which enables the internal first lead screw 1001 to move up and down along its axis; the movement of the first lead screw 1001 realizes precise height adjustment through a screw drive system, enabling the device to be conveniently adjusted to a suitable height as needed, achieving the effect of convenient and flexible height adjustment; after the height adjustment is completed, the operator further pushes the first telescopic rod 6, and this action causes the support base 7 to rotate accordingly; the support base 7 drives the connecting rod 5 through its rotation, causing the connecting rod 5 to slide on the track inside the limit disk 3; this sliding process not only ensures that the connecting rod 5 maintains stable movement on the track of the inner wall of the limit disk 3 but also further causes the arc plate 4 to rotate on the inner wall of the limit disk 3; through the movement of the connecting rod 5, the arc plate 4 also rotates on the inner wall of the limit disk 3; the rotational movement of the arc plate 4 is a key link, and through its unique arc design, precise adjustment at different angles is achieved.
[0024] Refer to Figure 1 , Figure 2 and Figure 3 , on one side of the outer wall of the installation column 2, a first hinge seat 11 is fixedly connected, and a hinge block 12 is rotatably connected inside the first hinge seat 11; on one side of the outer wall of the hinge block 12, a second lead screw 13 is fixedly connected, and one end of the second lead screw 13 is fixedly connected to a sliding rod 14; on one side of the outer wall of the support base 7, a second hinge seat 15 is fixedly connected, and a first limit cover 16 is rotatably connected inside the second hinge seat 15; the first limit cover 16 is slidably connected to the outer wall of the sliding rod 14, and a second knob 17 is threadedly connected to the outer wall of the second lead screw 13; a second limit cover 18 is rotatably connected to the outer wall of the second knob 17, and one end of the second limit cover 18 is fixedly connected to a spring 19; one end of the spring 19 is fixedly connected to the inner wall of the first limit cover 16, and the spring 19 is sleeved on the outer wall of the sliding rod 14;
[0025] Specifically, when the angle steel moves above the limit block 9, by rotating the second knob 17, the second lead screw 13 on its outer wall generates a corresponding movement; the movement of the second lead screw 13 further drives the second limit cover 18 to move synchronously on a specified track; as the second limit cover 18 moves, the spring 19 located inside it also undergoes corresponding telescopic changes; the movement of the second limit cover 18 is not just for simple displacement, but through this action, the spring 19 can be effectively adjusted in terms of its expansion and contraction; during the telescopic process of the spring 19, one end of it constantly abuts against the inner wall of the first limit cover 16, and through the elastic force of the spring 19, a certain buffering and stabilizing effect is generated inside the first limit cover 16; this structural design makes the adjustment process of the spring 19 more flexible and effective; through the fine adjustment of the spring 19, the relative position between the angle steel and the limit block 9 during the movement of the angle steel can be accurately controlled, ensuring that the limit block 9 can accurately limit the movement trajectory of the angle steel.
[0026] Working principle: When in use, the installation block 20 is installed in the use position, and then the operator holds and rotates the knob 1002 to make the screw rod 1001 move up and down. Through the movement of the screw rod 1001, the effect of facilitating height adjustment is achieved. At this time, the support seat 7 is rotated by pushing the telescopic rod 16. At this time, the connecting rod 5 at one end of the telescopic rod 16 is driven by the support seat 7 to slide inside the limit plate 3. At this time, the movement of the connecting rod 5 achieves the effect of driving the arc plate 4 to rotate on the inner wall of the limit plate 3. Through the movement of the arc plate 4, the effect of quickly adjusting the angle is achieved;
[0027] Secondly, when the angle steel moves above the limit block 9, the outer wall of the screw rod 13 is moved by turning the knob 17, thereby driving the limit cover 18 to move. At this time, the movement of the limit cover 18 drives the spring 19 to expand and contract. The spring 19 contracts, thereby achieving the effect of the spring 19 contacting the inner wall of the limit cover 16. At this time, the adjustment of the spring 19 can adjust the movement position of the limit block 9, thereby achieving the effect of slowing down the shaking of the angle steel when it moves.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
