Description

Technical Field

[0001] This utility model belongs to the field of lean pipe technology, specifically relating to an angle-adjustable locking connection accessory applied to lean pipes. Background Technology

[0002] Lean pipes are widely used in production line construction and material rack manufacturing due to their advantages such as flexible assembly and reusability. The connection between lean pipes is inseparable from various connecting accessories. Ideal connecting accessories should have both flexible angle adjustment capability and reliable high rigidity locking performance to meet the needs of lean pipe assembly under different working conditions.

[0003] However, when pursuing "high rigidity locking," the structural design of existing lean pipe connection accessories often results in a significant reduction in the flexibility of angle adjustment, making it difficult to meet the multi-angle connection requirements of lean pipes during assembly. Conversely, when focusing on "flexible angle adjustment," the connection rigidity of the accessories is significantly insufficient, making them prone to loosening and deformation under load, which seriously affects the stability and reliability of the lean pipe assembly structure, thus restricting the application of lean pipes in high-requirement scenarios. Utility Model Content

[0023] 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.

[0024] Please see Figures 1 to 4 This utility model provides an angle-adjustable locking connection accessory for use on lean pipes, including...

[0025] The base 1 has symmetrically distributed fastening seats 5 on one side, and a fixing cylinder 3 is provided at one end of the fastening seat 5. The fixing cylinder 3 is provided with a first serrated part 31. The base 1 serves as the basic support structure of the entire auxiliary component, providing an installation carrier for other components and ensuring the integrity of the structure. The symmetrically distributed fastening seats 5 ensure uniform force on the fixing cylinder 3 and improve structural stability. The first serrated part 31 on the fixing cylinder 3 is the key structure to achieve "high rigidity locking", providing conditions for engagement with the second serrated part 61 of the rotating cylinder 6 and ensuring the connection strength during locking.

[0026] The rotating cylinder 6 is rotatably connected to the two fixed cylinders 3, and the rotating cylinder 6 is provided with a second serrated part 61 that can cooperate with the first serrated part 31. The rotating cylinder 6 provides a structural basis for the angle adjustment of the lean tube through the rotatable connection with the fixed cylinders 3. The cooperation between the second serrated part 61 and the first serrated part 31 is the core structure for realizing the switching between "flexible adjustment" and "high rigidity locking". When engaged, the angle is locked, and when disengaged, it can rotate freely.

[0027] The adjustment component includes a groove 12 formed on the side surface of the base 1, a bidirectional threaded screw 8 rotatably disposed inside the groove 12, and a threaded seat 51 threadedly connected to the bidirectional threaded screw 8. The threaded seat 51 and the fastening seat 5 are fixedly connected. The groove 12 provides installation space for the bidirectional threaded screw 8 and the threaded seat 51, making the structure compact. The two-section reverse thread design of the bidirectional threaded screw 8 can drive the two threaded seats 51 to move simultaneously with one rotation, ensuring the synchronous movement of the fastening seat 5 and the fixed cylinder 3 and improving the consistency of adjustment. The fixed connection between the threaded seat 51 and the fastening seat 5 realizes the conversion of the rotational movement of the bidirectional threaded screw 8 to the linear movement of the fixed cylinder 3, which is the key to the power transmission for the engagement and disengagement of the first and second sawtooth sections.

[0028] In this embodiment, the height of the threaded seat 51 is consistent with the groove depth of the groove 12. A gap is left between the side surfaces of the fastening seat 5 and the base 1. The height of the threaded seat 51 is consistent with the groove depth of the groove 12, which can ensure that the threaded seat 51 moves smoothly in the groove 12 and avoid jamming. The gap between the fastening seat 5 and the side surface of the base 1 provides sufficient space for the movement of the fastening seat 5, prevents it from interfering with the base 1, and ensures the smoothness of the adjustment action.

[0029] In this embodiment, a first through hole is opened inside the fixed cylinder 3, a second through hole is opened inside the rotating cylinder 6, and a rotating shaft 4 passes through the first through hole and the second through hole. The rotating shaft 4 passes through the through holes of the fixed cylinder 3 and the rotating cylinder 6, realizing the rotational connection of the rotating cylinder 6 relative to the fixed cylinder 3. It is a structural support that allows the rotating cylinder 6 to flexibly adjust its angle, ensuring the stability and coaxiality of the rotation.

[0030] In this embodiment, a bearing 7 is also installed on the inner side of the groove 12. One end of the bidirectional threaded screw 8 is located inside the bearing 7. The bearing 7 supports and positions one end of the bidirectional threaded screw 8, reducing the frictional resistance when the bidirectional threaded screw 8 rotates, ensuring the smoothness and accuracy of the rotation of the bidirectional threaded screw 8, and thus improving the reliability of the entire adjustment component.

[0031] In this embodiment, a through hole is also provided on the front surface of the base 1 and communicates with the inside of the groove 12. The other end of the bidirectional threaded screw 8 is located outside the through hole and connected to a rotary knob 81. The rotary knob 81 provides a convenient force application point for the operator. The bidirectional threaded screw 8 can be driven to rotate by rotating the rotary knob 81. The operation is simple and labor-saving, which improves the convenience of user use.

[0032] In this embodiment, the device also includes an extension 62 disposed on the rotating drum 6 and a first fixing member 620 disposed at one end of the extension 62. The extension 62 and the first fixing member 620 provide a direct interface for the connection of the lean tube, thereby meeting the assembly requirements of the lean tube at different positions.

[0033] In this embodiment, a receiving cavity 11 is also provided inside the base 1, and a locking bolt 2 is provided on the base 1. The receiving cavity 11 can be used to accommodate the connection end or related components of other lean tubes, and the locking bolt 2 can fasten the components in the receiving cavity to achieve a stable connection between the base 1 and another lean tube, which enriches the connection function of the auxiliary parts and improves the diversity of its applicable connection scenarios.

[0034] The working principle and usage process of this utility model are as follows: Insert a lean pipe to be connected into the receiving cavity 11 of the base 1, and tighten the locking bolt 2 to stably connect the lean pipe to the base 1.

[0035] Connect and fix the other lean pipe to the first fixing component 620;

[0036] When the operator rotates the rotary knob 81 at the outer end of the bidirectional threaded screw 8, due to the two reverse thread designs of the bidirectional threaded screw 8, the two threaded seats 51 will move away from each other in the groove 12.

[0037] The threaded seat 51 drives the corresponding fastening seat 5 to move, thereby causing the fixed cylinder 3 to move away from the rotating cylinder 6, so that the first serrated part 31 on the fixed cylinder 3 separates from the second serrated part 61 on the rotating cylinder 6.

[0038] At this time, the rotating drum 6 can rotate freely around the rotating shaft 4 that passes through the fixed drum 3 and the rotating drum 6. The operator can rotate the rotating drum 6 to adjust the angle of another lean tube according to the angle requirements of the lean tube assembly.

[0039] Once the angle is adjusted to the correct position, rotate the knob 81 in the opposite direction to make the bidirectional threaded screw 8 drive the two threaded seats 51 to move closer to each other. The threaded seats 51 drive the fastening seat 5 to move, thereby causing the fixed cylinder 3 to move closer to the rotating cylinder 6, so that the first sawtooth part 31 and the second sawtooth part 61 are tightly engaged.

[0040] At this point, the rotating drum 6 is firmly locked and can no longer rotate around the rotating shaft 4. A high-rigidity angle lock is achieved between the two lean tubes, completing the connection and assembly of the lean tubes.

[0041] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
