Description

Technical Field

[0001] This utility model belongs to the technical field of self-locking support frames, specifically a self-locking support frame for supporting the end of a cantilever shaft. Background Technology

[0002] Self-locking support frames achieve self-locking through a unique structural design, ensuring the cantilever shaft remains stable under load and preventing support failure due to vibration, offset, or external forces. They are widely used in mechanical systems that require high-precision and high-reliability support. In existing self-locking support frames, the tilting wheel mounted on the top is moved away from the outside of the two swing arms, thus releasing the swing arms hinged to the support frame and opening the distance between the two swing arms to facilitate locking the object. However, when the operator releases the fixation of the two swing arms and pulls one of the swing arms, the swing arm is affected by its own weight, causing it to droop to one side of the support frame. This means that when using the self-locking mounting frame to open, it is necessary to manually support the swing arm to open, which increases the workload and reduces the convenience of operation. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a self-locking support frame for supporting the cantilever shaft end.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-locking support frame for supporting the cantilever shaft end, comprising a support frame, with a first swing arm and a second swing arm respectively provided on both sides of the support frame, a fastening arm hinged to the top of the second swing arm, an eccentric wheel provided inside the fastening arm, the outer surface of the eccentric wheel being movably connected to the outer wall of the first swing arm, a handle provided on the outer side of the eccentric wheel, a mounting base provided at the bottom of the support frame, a spring provided inside the mounting base, and the other end of the spring being connected to the outer wall of the support frame.

[0005] Preferably, the first and second swing arms have different shapes, and both the first and second swing arms are provided with slots.

[0006] Preferably, one end of the swing arm is arc-shaped, and the outer side of the arc is movably connected to a spring.

[0007] Preferably, a protrusion is provided on the inner side of the top of the first swing arm, and a concave block is provided on the inner side of the top of the second swing arm, with the inner side of the protrusion and the inner side of the concave block being adapted to each other.

[0008] Preferably, both the first and second swing arms are provided with adjusting bolts inside, and the inner side of the adjusting bolts extends to the outside of the first and second swing arms.

[0009] Preferably, both the first and second swing arms are provided with slots located on the outside of the protrusions and concave blocks, and the protrusions and concave blocks are provided with slots.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a spring and a swing arm. When the operator releases the self-locking mechanism of the support frame, the swing arm will compress the spring during rotation. The spring's elastic force will then provide elastic support for the swing arm, preventing it from rotating out of the support frame. This self-locking support frame reduces the amount of manual support required for the swing arm, prevents it from drooping below the support frame due to its own weight, and improves operational convenience.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1

[0015] like Figures 1 to 4 As shown, this is the first embodiment of the utility model, providing a self-locking support frame for supporting the cantilever shaft end, including a support frame 1. A swing rod 2 and a swing rod 3 are respectively provided on both sides of the support frame 1. A fastening arm 4 is hinged to the top of the swing rod 3. An eccentric wheel 5 is provided inside the fastening arm 4. The outer surface of the eccentric wheel 5 is movably connected to the outer wall of the swing rod 2. A handle 6 is provided on the outer side of the eccentric wheel 5. A mounting seat 8 is provided at the bottom of the support frame 1. A spring 9 is provided inside the mounting seat 8. The other end of the spring 9 is connected to the outer wall of the support frame 1. When the operator pulls the handle 6 upwards, the eccentric wheel 5 rotates around its shaft end. Because the shaft end of the eccentric wheel 5 is not aligned with the axis, it releases the pressure on the swing arm 2 during rotation, thereby releasing the fixation on the swing arm 2. Then, the object clamped between the swing arm 2 and the swing arm 3 is removed. At this time, the swing arm 2 will rotate, and the pressure will cause the other side of the shaft end of the swing arm 2 to compress the spring 9. The elastic force of the spring 9 will increase the support force on the other end of the swing arm 2, preventing the swing arm 2 from drooping to one side of the support frame 1. Thus, the support of the spring 9 reduces the amount of manual support work and improves the convenience of operation.

[0016] Example 2

[0017] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the first pendulum rod 2 and the second pendulum rod 3 have different shapes, and both the first pendulum rod 2 and the second pendulum rod 3 are provided with slots. When the first swing arm 2 and the second swing arm 3 are hinged together, their grooves form a circular groove. By placing the object to be clamped in the circular groove beforehand, and then closing it, the object is fixed between the first swing arm 2 and the second swing arm 3, which brings convenience to the operator.

[0018] Among them, the end of the rocker arm 2 is arc-shaped, and the outer side of the arc shape is movably connected to the spring 9; When the swing arm 2 rotates around the shaft end, the arc-shaped compression spring 9 at the end of the swing arm 2 prevents the swing arm 2 from falling off the outside of the support frame 1 through the elastic force generated by the spring 9, which facilitates the self-locking of the support by the subsequent operators.

[0019] Among them, a protrusion is provided on the inner side of the top of the first swing arm 2, and a concave block is provided on the inner side of the top of the second swing arm 3, with the inner side of the protrusion and the inner side of the concave block matching each other. When the first rocker arm 2 and the second rocker arm 3 are closed, the protrusion and the concave block are engaged together, which limits the movement of the first rocker arm 2 and the second rocker arm 3 and prevents them from locking themselves securely.

[0020] Among them, both the first swing arm 2 and the second swing arm 3 are equipped with adjusting bolts 7, and the inner side of the adjusting bolts 7 extends to the outside of the first swing arm 2 and the second swing arm 3; When the self-locking support frame is in use, rotating the adjusting bolt 7 compresses the opening size of the swing arm 1 2 and swing arm 2 3, which facilitates the clamping and fixing of objects of different sizes, thus improving the practicality of the self-locking support frame.

[0021] Among them, the inside of the first swing arm 2 and the second swing arm 3 are provided with slots located on the outside of the protrusion and the concave block, and the inside of the protrusion and the concave block are provided with slot holes; By placing screws in the slots, the protrusions and concave blocks are fixed to the rocker arm 1 2 and rocker arm 2 3 respectively, making it convenient for operators to disassemble or install them, thus improving the ease of use for operators.

[0022] Working principle and usage process of this utility model: First, when the operator uses the self-locking support frame, pulling the handle 6 causes the eccentric wheel 5 to release the pressure on the swing arm 2. Then, rotating the swing arm 2 opens the opening between the swing arm 2 and the swing arm 3, making it easier to remove the object clamped inside the swing arm 2 and the swing arm 3. At this time, the spring 9 is compressed at the shaft end of the swing arm 2. The elastic force of the spring 9 drives the swing arm 2 to reset, so that it is reassembled with the swing arm 3. This prevents the swing arm 2 from drooping at the bottom of the support frame 1, which would make it inconvenient to use. Thus, the spring 9 supports the swing arm 2, making it easier for the operator to use the self-locking support frame, bringing convenience to the operator.
