Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a multi-angle adjustable automatic locking connector. Background Technology

[0002] In modern industry, connectors are widely used as key components for connecting parts. However, traditional connectors have many limitations in practical use and cannot meet the requirements for efficient and reliable connections.

[0003] First, most traditional connectors have a fixed connection angle, which cannot adapt to the diverse connection needs in complex scenarios. During the installation of complex mechanical equipment, due to space constraints, components often need to be connected at specific angles. However, traditional fixed-angle connectors cannot be flexibly adjusted, which not only leads to installation difficulties but sometimes even requires redesigning and modifying the equipment structure, significantly increasing production and time costs.

[0004] Secondly, some connectors with angle adjustment functions have significant defects in their locking methods. Some connectors use manual bolt tightening to fix the connection angle, which is cumbersome, requires specialized tools, and during prolonged use, the bolts are prone to loosening due to vibration and other factors, causing changes in the connection angle and interfering with normal equipment operation. Other connectors using a snap-lock structure have unstable locking performance and are easily dislodged under external impact, failing to guarantee connection reliability.

[0005] Furthermore, traditional connectors have poor sealing performance. In harsh environments such as humid and dusty conditions, external moisture and dust can easily penetrate the connector, damaging the connecting components, shortening the connector's lifespan, and reducing the safety of equipment operation.

[0006] In summary, existing connectors have significant shortcomings in terms of angle adjustment flexibility, locking stability, and sealing performance. Taking the connectors for common sun umbrellas, beach umbrellas, and fishing umbrellas as examples, their canopies can only be adjusted in one direction (forward / backward or left / right), resulting in a very limited shading angle. Therefore, developing a connector with multi-angle adjustability, automatic locking, and excellent sealing performance is of significant practical importance in meeting the needs of modern industry. This new type of connector will overcome traditional limitations, such as enabling omnidirectional adjustable shading, providing a more efficient and reliable connection solution for practical applications.

[0031] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; for those skilled in the art, the specific meaning of the above term in this utility model can be understood according to the specific circumstances.

[0033] I. Working principle of this utility model:

[0034] The multi-angle adjustable automatic locking connector of this utility model mainly includes a first connecting tube 1, a second connecting tube 2, a third connecting tube 3 connected in series axially, and two sets of limiting mechanisms. Among them, the top end of the first connecting tube 1 and the bottom end of the third connecting tube 3 are provided with a plug-in part 4 with anti-slip texture. This plug-in part is used for quick plugging with other components. The anti-slip texture design can increase friction and prevent loosening during the plugging process.

[0035] The top of the second connecting pipe 2 and the top of the third connecting pipe 3 are provided with through-type assembly grooves 5, and their axial directions are respectively perpendicularly intersecting each other. The bottom ends of the first connecting pipe 1 and the second connecting pipe 2 are provided with toothed assembly heads 6 that mesh with the assembly grooves 5. Through the meshing of the assembly heads with the assembly grooves, the angle between the connecting pipes can be adjusted and initially positioned.

[0036] The limiting mechanism is a key component for achieving automatic locking of the connector, and it includes a latching assembly 7, a button assembly 8, and a spring return system. The latching assembly 7 is located inside the second connecting tube 2 and the third connecting tube 3. The upper part of the latching assembly 7 has a locking groove 71 that matches the tooth profile of the assembly head 6. When the assembly head is inserted into the mounting groove and adjusted to a suitable angle, the locking groove can tightly engage with the tooth profile of the assembly head, achieving automatic locking. The lower part of the latching assembly 7 slides with the groove 81 of the button assembly 8 via a protrusion 72. The unlocking of the latching assembly is controlled by operating the button assembly.

[0037] The button assembly 8 includes a groove 81 and a pressing plate 82. The second connecting pipe 2 and the third connecting pipe 3 are provided with through holes 9. The spring reset system includes a telescopic spring 10 disposed within the through hole 9, with its two ends abutting against the pressing plate 82 and the inner wall of the through hole 9, respectively. When the pressing plate is pressed, the telescopic spring is compressed, and the button assembly, through the groove engaging with the protrusion of the latch assembly, moves the latch assembly downwards, causing the locking teeth to separate from the mounting head, thus unlocking. After the pressing plate is released, under the elastic force of the telescopic spring, the button assembly and the latch assembly return to their original positions, re-locking.

[0038] To further improve the connection stability of the connector, a coaxial through hole 11 is provided between the assembly slot 5 and the assembly head 6, through which a long screw 12 is inserted. Both ends of the long screw are equipped with anti-loosening nuts and flat washers. The long screw, in addition to the locking mechanism of the snap-fit ​​assembly, further enhances the reliability of the connection and prevents relative rotation between the connecting tubes. Simultaneously, the surface of the long screw 12 is coated with a wear-resistant coating, and its diameter is clearance-fitted with the through hole 11 with a tolerance of H8 / f7. The wear-resistant coating improves the wear resistance of the long screw, extending its service life. The appropriate clearance tolerance ensures that the long screw can rotate freely within the through hole while providing sufficient tightening force.

[0039] In addition, the button assembly 8 is provided with a guide boss 83 and a guide groove 13 is opened on the inner wall of the through hole 9. The cooperation between the guide boss and the guide groove can ensure the stability of the button assembly during movement, prevent it from shifting, and ensure the normal unlocking and locking operation of the buckle assembly.

[0040] The upper end of the guide boss 83 and the lower end of the protrusion 72 are both slope-shaped structures that cooperate with each other. When the button is released, the spring extends and the two slopes slide to fit together seamlessly, so that all components fit together tightly as one, thus ensuring that the external support points at both ends of the device are free from shaking and gaps.

[0041] Multiple sealing grooves are provided on the outer circumference of the plug part 4. Sealing rings can be installed in the sealing grooves. Through the sealing effect of the sealing rings, external moisture, dust and other substances can be effectively prevented from entering the connector, thereby improving the sealing performance and service life of the connector.

[0042] When connecting two components, first insert the insertion parts of the first connecting pipe 1 and the third connecting pipe 3 into the corresponding component interfaces. Then, according to actual needs, rotate the first connecting pipe 1 and the second connecting pipe 2 to rotate the assembly head within the assembly groove and adjust it to a suitable connection angle. During the adjustment process, the initial positioning of the angle can be achieved due to the toothed engagement between the assembly head and the assembly groove.

[0043] Once the angle is adjusted, the locking groove 71 of the snap-fit ​​assembly 7 will automatically engage tightly with the teeth of the assembly head 6 to achieve automatic locking and ensure that the angle between the connecting tubes is fixed. The lower end of the locking groove (71) is provided with a guide post 711, and a compression spring is sleeved on the guide post 711. At this time, the long screw 12 further tightens the connecting tube and improves the stability of the connection.

[0044] When disassembly or readjustment of the connection angle is required, pressing the press plate 82 of the button assembly 8 compresses the telescopic spring 10. The button assembly engages with the protrusion 72 of the latch assembly 7 via the groove 81, causing the latch assembly to move downwards, separating the locking teeth from the mounting head and unlocking the device. At this point, the connecting tube can be easily rotated to adjust to a new angle. After releasing the press plate, the button assembly and latch assembly return to their original positions under the elastic force of the telescopic spring, re-locking the device.

[0045] II. Implementation Method:

[0046] First, prepare the multi-angle adjustable automatic locking connector of this utility model, check whether each component is intact, whether the anti-slip texture of the plug part 4 is clear, and whether the sealing groove is complete.

[0047] Then, insert the connector of the first connecting tube 1 into a joint component interface of the robotic arm, ensuring a secure connection. Next, insert the connector of the third connecting tube 3 into another joint component interface.

[0048] Based on the movement requirements of the robotic arm, the first connecting pipe 1 and the second connecting pipe 2 are rotated. By observing the meshing between the assembly head 6 and the assembly groove 5, the appropriate connection angle is adjusted. During the adjustment process, due to the toothed engagement between the assembly head and the assembly groove, the change in angle and positioning can be clearly felt.

[0049] Once the angle is adjusted, the snap-fit ​​assembly 7 will automatically engage with the assembly head 6, achieving automatic locking. At this point, use a tool to pass the long screw 12 through the through hole 11, install anti-loosening nuts and flat washers at both ends, and tighten the nuts to further reinforce the connection.

[0050] During the operation of the robotic arm, if it is necessary to adjust the joint angle, press the press plate 82 of the button assembly 8, the telescopic spring 10 is compressed, the buckle assembly 7 is unlocked, the rotating connecting tube is adjusted to a new angle, and then the press plate is released, and the buckle assembly automatically relocks.

[0051] Because a sealing ring is installed in the sealing groove of the plug part 4, even in the presence of dust in the production line environment, dust can be effectively prevented from entering the connector, ensuring the normal operation of the connector and the stability of the robotic arm.

[0052] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
