Description

Technical Field

[0001] This invention relates to the field of steel structure connection fasteners, and in particular to a quick-connect bracket and its assembly method, which is widely used in the detachable connection of prefabricated brackets, cable trays, and equipment support beams. Background Technology

[0002] In the assembly and construction of steel structure profiles such as channel steel and photovoltaic brackets, threaded rods in conjunction with C-shaped steel brackets are commonly used to suspend and fix pipelines. The connection and locking structure between the steel profile and the threaded rod directly determines the installation efficiency and operational stability of the bracket. Traditionally, double-nut clamping and locking are used, requiring multiple tightening of the nuts to complete assembly and leveling. This process is cumbersome for high-altitude operations, difficult to level, and prone to loss of loose parts, resulting in low construction efficiency.

[0003] There are already many publicly available locking structures. Among them, utility model patent CN216951150U discloses a novel channel steel locking structure. This solution uses a locking body with a threaded connecting pipe to achieve profile locking. It improves the shock resistance of the connector by adding rubber shock-absorbing pads and double-layer buffer springs to absorb vibration loads. However, the overall components are complex, the assembly steps are numerous, the on-site quick assembly effect is poor, and there is no eccentric hole self-tightening structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a bracket quick-assembly connector and its assembly method that have a reasonable structural design, integrated structure, and rapid assembly.

[0005] The technical solution adopted by the present invention to solve the above problems is as follows: the quick-connect bracket includes a locking component and a slotted base; characterized in that: the locking component is provided with a through hole and an external thread, and the through hole is provided with an internal thread; the slotted base is provided with a through hole, and the inner wall of the through hole is provided with an internal thread that mates with the external thread; the through hole is an eccentric hole, and the central axis of the through hole is offset from the central axis of the external thread.

[0006] Furthermore, the locking assembly of the present invention has an integrally formed top pressure plate and a tightening head, with the top pressure plate located in the middle of the locking assembly and the tightening head located at the upper end of the locking assembly.

[0007] Furthermore, the grooved base of the present invention is an integrally formed convex rigid base structure.

[0008] Furthermore, the internal thread described in this invention is a through-type internal thread.

[0009] Furthermore, the grooved base of the present invention has integrally formed sloping abutment surfaces on both sides.

[0010] Furthermore, the central axis of the through hole in this invention is offset relative to the central axis of the external thread toward the side where the locking assembly and the lead screw abut.

[0011] An assembly method for a quick-connect bracket, characterized by comprising the following steps: S1: The locking assembly is pre-screwed into the slotted base, and the slotted base is then inserted into the steel section to be fixed.

[0012] S2: Hold the tightening head of the locking component and rotate the locking component and the slotted base synchronously by 90°, so that the slotted base is locked and limited to the inner edge of the channel steel.

[0013] S3: Rotate the locking assembly until the through hole is in the clearance position, leaving a coaxial channel for the lead screw to pass through.

[0014] S4: The lead screw is vertically inserted from top to bottom through the through hole one of the locking assembly and the through hole two of the slotted base. The lead screw has no thread interference and the pre-installation is completed directly.

[0015] S5: Hold and tighten the head again to rotate the locking assembly 180° relative to the slotted base; on the one hand, the external thread of the locking assembly and the internal thread of the slotted base continue to tighten, and the top pressure plate presses the slotted base to lock the entire set of connectors onto the profile steel; on the other hand, the through hole rotates synchronously, and its internal thread engages with the screw thread to achieve anti-loosening locking, thus completing the entire installation.

[0016] S6: Disassembly: Rotate the locking assembly 180° in the opposite direction, reset the through hole to the clearance position, loosen the thread engagement, and directly pull out the lead screw to separate the connecting part from the steel section.

[0017] Compared with the prior art, the present invention has the following advantages and effects: The present application has an integrated structure, consisting of two parts: a locking component and a slotted base. It is simple to process, has low production cost, and requires no alignment calibration during assembly. Compared with the ordinary multi-turn tightening method of bolts, the present application has fewer effective locking turns, shortens the installation time, and meets the needs of rapid on-site construction. It does not require consumables such as anti-loosening adhesive and disposable gaskets. Locking and disassembly do not cause structural damage and can be reused an unlimited number of times, reducing the cost of later operation and maintenance. Attached Figure Description

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Similarly, the use of terms such as "above," "below," and "one" in this specification is solely for clarity and not intended to limit the scope of the invention. Any changes or adjustments to these relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0028] This embodiment includes a locking assembly 1 and a slotted base 2; the locking assembly 1 is provided with a through hole 11 and an external thread 12, and an internal thread 13 is provided in the through hole 11, the internal thread 13 being a through internal thread; the slotted base 2 is provided with a through hole 21, and the inner wall of the through hole 21 is provided with an internal thread 22 that mates with the external thread 12; the through hole 11 is an eccentric hole, and the central axis of the through hole 11 is offset from the central axis of the external thread 12, that is, the central axis of the through hole 11 is offset relative to the central axis of the external thread 12 toward the side where the locking assembly 1 and the lead screw 4 abut.

[0029] The locking assembly 1 has an integrally formed top pressure plate 14 and a tightening head 15. The top pressure plate 14 is located in the middle of the locking assembly 1, and the tightening head 15 is located at the upper end of the locking assembly 1. The top pressure plate 14 is used to axially press the end face of the groove base to achieve end face limiting; the tightening head 15 is used for tool clamping and rotation to facilitate overall rotation and locking.

[0030] The grooved base 2 is an integrally formed convex rigid seat structure, and both sides have integrally formed sloping abutment surfaces 23. The sloping abutment surfaces 23 are attached to the inclined surface of the grooved steel 3. After locking, the grooved base 2 is anti-slip and anti-rotation positioning, ensuring that it will not be over-installed.

[0031] An assembly method for a bracket quick-connect connector includes the following steps: S1: The locking component 1 is pre-screwed into the slotted base 2, and the slotted base 2 is inserted into the steel section 3 to be fixed.

[0032] S2: Hold the tightening head 13 of the locking component 1, and rotate the locking component 1 and the slotted base 2 synchronously by 90°, so that the slotted base 2 is locked and limited to the inner edge of the channel steel 3. This completes the locking and fixing of the slotted base 2 and the channel steel 3, preventing the base from wobbling or falling off.

[0033] S3: Rotate the locking assembly 1 until the through hole 11 is in the clearance position, leaving a coaxial channel for the lead screw 4 to pass through.

[0034] S4: The lead screw 4 is vertically inserted from top to bottom through the through hole 11 of the locking assembly 1 and the through hole 21 of the slot base 2. The lead screw 4 has no thread interference and can be directly inserted for pre-installation.

[0035] S5: Hold and tighten the head again to rotate the locking assembly 1 180° relative to the slotted base 2; on the one hand, the external thread 12 of the locking assembly 1 and the internal thread 22 of the slotted base 2 continue to tighten, and the top pressure plate 14 presses the slotted base 2 to lock the entire set of connecting parts onto the steel section 3; on the other hand, the through hole 11 rotates synchronously, and its internal thread 13 engages with the screw 4 to achieve anti-loosening locking and complete the installation.

[0036] S6: Disassembly: Rotate the locking assembly 1 180° in the opposite direction, reset the through hole 11 to the clearance state, loosen the thread engagement, and directly pull out the lead screw 4 to separate the connecting piece from the steel section 3.

[0037] In use, the locking assembly 1 and the slotted base 2 are pre-assembled together. The slotted base 2 is then inserted into the steel section 3 to be fixed. The entire assembly is rotated 90 degrees, and the ramp abutment surface 23 is aligned with the ramped surface of the groove step of the steel section 3. The lead screw 4 is then directly inserted into the through hole 11. When it reaches the appropriate position, the locking assembly 1 is rotated 180 degrees so that the internal thread 13 engages with the lead screw 4, achieving quick installation and improving installation efficiency.

[0038] All equivalent or simple variations made based on the structure, features and principles described in this patent concept are included within the protection scope of this patent.
