Description

Technical Field

[0001] This utility model relates to the technical field of common connectors for steel pipe clamp plates, specifically to a multi-directional rotary locking connector block. Background Technology

[0002] In the field of industrial automation equipment, connecting blocks are commonly used connectors for steel pipe clamp plates, and their performance directly affects the flexibility and stability of the equipment. Traditional connecting blocks, such as right-angle connecting blocks, have the drawback of fixed angles, meaning they can only be installed in a fixed direction and cannot be adjusted according to actual needs, which greatly limits the layout and functional expansion of the equipment.

[0003] While some existing adjustable connectors can achieve angle adjustment, their complex structural design presents numerous drawbacks during use. For example, ball joint connectors that rely solely on friction for locking are prone to loosening after adjustment, making it difficult to guarantee connection stability and potentially posing safety hazards during equipment operation. Furthermore, methods that achieve multi-angle adjustment through multiple hinges and adapters are not only cumbersome to operate, increasing installation and maintenance costs, but also reduce overall structural reliability due to the increased number of components. Additionally, traditional ball-and-socket connectors suffer from insufficient locking force, while gear-type connectors have a fixed angle that cannot be finely adjusted. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This embodiment provides a multi-directional rotating locking connection block, including a first connection block body 1 and a second connection block body 2, both of which are three-dimensional.

[0020] To facilitate understanding of the technical features of this case, in this embodiment and the accompanying drawings, reference numeral 1a represents the height direction of the first connecting block body 1, reference numeral 1b represents the width direction of the first connecting block body 1, reference numeral 1c represents the length direction of the first connecting block body 1; reference numeral 2a represents the height direction of the second connecting block body 2, and reference numeral 2b represents the width direction of the second connecting block body 2.

[0021] Furthermore, the first connecting block body 1 includes a first connecting part 11 and a first tightening part 12. The first connecting part 11 and the first tightening part 12 are integrally formed. The end of the first connecting part 11 away from the first tightening part 12 is round, mainly to facilitate the rotation of the first connecting block body 1 relative to the second connecting block body 2 and adjust the included angle between the two.

[0022] Furthermore, the first connecting part 11 has a first countersunk bolt connecting hole 111 along the height direction 1a, and the first tightening part 12 has a through first tightening hole 121 along the width direction 1b.

[0023] Furthermore, the first elastic part 12 has a through first elastic groove 122 at one end away from the first connecting part 11 along the width 1b direction, and the first elastic groove 122 communicates with the first elastic hole 121.

[0024] Furthermore, the first tightening part 12 has a first countersunk bolt tightening hole 123 along the height direction 1a, and the first countersunk bolt tightening hole 123 passes through the first tightening groove 122.

[0025] Furthermore, when a steel pipe or other components to be connected need to be connected through the first connecting block body 1, taking a steel pipe as an example, the steel pipe is inserted into the first tightening hole 121, and the first countersunk bolt tightening hole 123 is threaded with a bolt. By tightening the bolt with a cross wrench, the width of the first tightening groove 122 gradually narrows, so that the first tightening hole 121 generates a large clamping force to clamp and fix the steel pipe.

[0026] Furthermore, one end face of the first connecting portion 11 is on the same horizontal plane as one end face of the first elastic portion 12, and the thickness of the first connecting portion 11 is 1 / 2 the thickness of the first elastic portion 12.

[0027] Furthermore, when the two first connecting block bodies 1 are connected, the thickness of the connection point is consistent with the thickness of the first loose part 12 of the first connecting block body 1, which will not generate extra space occupation and will not cause motion interference.

[0028] Furthermore, the second connecting block body 2 includes a second connecting portion 21 and a second tightening portion 22, which are integrally formed. The second connecting portion 21 has a second countersunk bolt connecting hole 211 along the height direction 2a, and the second tightening portion 22 has a through second tightening hole 221 along the height direction 2a. The end of the second tightening portion 22 away from the second connecting portion 21 has a through second tightening groove 222 along the height direction 2a, and the second tightening groove 222 communicates with the second tightening hole 221.

[0029] Furthermore, the second tightening part 22 has a second countersunk bolt tightening hole 223 along the width direction 2b, and the second countersunk bolt tightening hole 223 passes through the second tightening groove 222.

[0030] Furthermore, the shape of the second connecting block body 2 is the same as that of the first connecting block body 1, and the height, width and length of the second connecting portion 21 of the second connecting block body 2 are the same as those of the first connecting portion 11 of the first connecting block body 1; the height, width and length of the second tightening portion 22 of the second connecting block body 2 are the same as those of the first tightening portion 12 of the first connecting block 1.

[0031] Furthermore, the first connecting parts 11 of the two first connecting block bodies 1 are bolted together through the first countersunk bolt connecting holes 111 to achieve a fixed connection of different connecting parts on the same horizontal plane. The first connecting parts 11 of the first connecting block body 1 and the second connecting parts 21 of the second connecting block body 2 are bolted together to achieve a fixed connection of different connecting parts on mutually perpendicular planes.

[0032] Specifically, when it is necessary to achieve a fixed connection (parallel connection) of different connectors on the same horizontal plane, firstly, one connector is inserted into the first tightening hole 121 of one of the first connecting block bodies 1 and clamped for a fixed connection, and another connector is inserted into the first tightening hole 121 of another of the first connecting block bodies 1 and clamped for a fixed connection; secondly, the first countersunk bolt connection hole 111 in the first connecting part 11 of one of the first connecting block bodies 1 and the first countersunk bolt connection hole 111 in the first connecting part 11 of another of the first connecting block bodies 1 are arranged concentrically, and after rotating to the angle to be adjusted (adjustable from 0-180°), a fixed connection is made by bolts, and the connection of the parallel-arranged connectors is completed.

[0033] Specifically, when achieving a fixed connection (cross-shaped connection) between different connectors on mutually perpendicular planes, firstly, one connector is inserted into the first tightening hole 121 of the first connector body 1 and clamped for a fixed connection, and the other connector is inserted into the second tightening hole 221 of the second connector body 2 and clamped for a fixed connection; secondly, the first countersunk bolt connection hole 111 in the first connecting part 11 of the first connector body 1 and the second countersunk bolt connection hole 211 in the second connecting part 21 of the second connector body 2 are arranged concentrically. After rotating to the required angle (adjustable from 0-180°), the connection is fixed by bolts, and the cross-shaped connector connection is completed.

[0034] Furthermore, threaded holes are provided on the inner walls of the first countersunk bolt connection hole 111, the second countersunk bolt connection hole 211, the first countersunk bolt tightening hole 123, and the second countersunk bolt tightening hole 223. In this embodiment, the self-tapping threaded hole has the following advantages: 1. Simplified assembly process: No additional nuts or other auxiliary connecting parts are needed; the bolt can be directly screwed into the threaded hole to complete the connection, reducing the number of parts and operation steps in the assembly process and improving assembly efficiency; 2. Space saving: Compared with the connection method using nuts and bolts, the structural component with a self-tapping threaded hole does not require leaving space on the other end of the bolt to install the nut. In the case of limited space, it can effectively save space and make the structural design more compact; 3. Enhanced structural strength: The threaded hole is directly machined on the structural component, forming an integral whole with the structural component. Compared with the connection method using nuts, it can better transmit force when bearing load, reduce stress concentration, and thus enhance the overall strength and stability of the structure; 4. Improved anti-loosening performance: In some vibration environments, the structural component with a self-tapping threaded hole, when used with a bolt, can achieve better anti-loosening performance by reasonably designing the thread parameters and adopting appropriate anti-loosening measures (such as applying thread-locking agent). Compared with the ordinary nut connection method, it is more resistant to loosening caused by vibration and improves the reliability of the connection.

[0035] Furthermore, when the two first connecting block bodies 1 are connected or the first connecting block body 1 is connected to the second connecting block body 2, the two can be adjusted at multiple angles (0-180° arbitrary angle adjustment), with a larger adjustment range, stronger applicability and compatibility, and can be widely used in the field of automated industry.

[0036] Furthermore, both the first connecting block body 1 and the second connecting block body 2 can be produced modularly, using lightweight aluminum materials to reduce weight and lower costs.

[0037] Furthermore, the diameters of the first loosening hole 121 of the first connecting block body 1 and the second loosening hole 221 of the second connecting block body 2 can be opened to 12mm, 20mm, etc., so as to realize the connection of pipes with different diameters such as Ø12 and Ø20.

[0038] Furthermore, the first connecting block body 1 and the second connecting block body 2 are not only for the fixed connection of pipes. When the first loosening hole 121 and the second loosening hole 221 are opened as squares or rectangles, the connection of profiles can be realized, which has a wide range of applicable scenarios and application fields.

The first tightening part 12 has a through first tightening hole 121 along the width direction 1b. The end of the first tightening part 12 away from the first connecting part 11 has a through first tightening groove 122 along the width direction 1b. The first tightening groove 122 communicates with the first tightening hole 121.

[0040] Specifically, when it is necessary to achieve a fixed connection (parallel connection) of different connectors on the same horizontal plane, firstly, one connector is inserted into the first tightening hole 121 of one of the first connecting block bodies 1 and clamped for a fixed connection, and another connector is inserted into the first tightening hole 121 of another of the first connecting block bodies 1 and clamped for a fixed connection; secondly, the first countersunk bolt connection hole 111 in the first connecting part 11 of one of the first connecting block bodies 1 and the first countersunk bolt connection hole 111 in the first connecting part 11 of another of the first connecting block bodies 1 are arranged concentrically, and after rotating to the angle to be adjusted (adjustable from 0-180°), a fixed connection is made by bolts, and the connection of the parallel-arranged connectors is completed.

[0041] When it is necessary to achieve a fixed connection (cross-shaped connection) of different connectors with mutually perpendicular planes, firstly, one connector is inserted into the first tightening hole 121 of the first connector body 1 and clamped for a fixed connection, and the other connector is inserted into the second tightening hole 221 of the second connector body 2 and clamped for a fixed connection; secondly, the first countersunk bolt connection hole 111 in the first connecting part 11 of the first connector body 1 and the second countersunk bolt connection hole 211 in the second connecting part 21 of the second connector body 2 are arranged concentrically. After rotating to the required angle (adjustable from 0-180°), the connection is fixed by bolts, and the cross-shaped connector connection is completed.
