Description

Technical Field

[0001] This invention belongs to the field of building construction support technology, specifically relating to an anti-loosening connection mechanism and scaffolding. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. Currently, the most commonly used type is the disc-lock scaffolding. Disc-lock scaffolding uses disc-locks as connectors, steel pipes as the main components, and the uprights are made by welding a disc-lock to a steel pipe of a certain length every 0.60 meters, with a connecting rod at the top. The horizontal bars are made by welding clamps with pins to both ends of the steel pipe. This connection method is prone to detachment during use due to vibration or impact, affecting the stability and safety of the scaffolding.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN107060316A discloses an anti-loosening disc-lock scaffolding. After inserting the pin on the horizontal bar into the plug sleeve, the scaffolding is prevented from loosening when the load pressure is too high or when it is subjected to other lateral forces by setting the horizontal support beam. However, it can still detach when subjected to vibration or collision.

[0004] Therefore, it is necessary to design an anti-loosening connection mechanism that improves connection stability and prevents detachment under vibration and impact, and to design scaffolding with such an anti-loosening connection mechanism to solve the current technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an anti-loosening connection mechanism and scaffolding that improves connection stability and prevents detachment under vibration and impact.

[0006] The technical solution of the present invention is as follows: an anti-loosening connection mechanism, including a vertical pole and a horizontal pole. A buckle plate is fixedly installed on the vertical pole, and four insertion holes are evenly arranged on the buckle plate. A connecting handle matching the insertion holes is provided at the end of the horizontal pole. A connecting end is provided at the bottom of the connecting handle. A locking hole is provided through the side of the connecting end. A pull-down assembly is threadedly connected to the vertical pole below the buckle plate. A buckle assembly fitted on the outside of the vertical pole is rotatably provided at the top of the pull-down assembly. The buckle assembly has an L-shaped fastener matching the locking hole.

[0007] The pull-down assembly has a threaded sleeve with an internal thread inside. The outside of the upright below the buckle plate has an external thread that matches the internal thread. The threaded sleeve is threaded onto the outside of the pull rod. A snap-fit ​​support plate is rotatably mounted on the top of the threaded sleeve. Four L-shaped fasteners are arranged in a circumferential array on the top of the snap-fit ​​support plate.

[0008] The upper inner side of the threaded sleeve is provided with an annular groove, and the bottom of the snap-fit ​​support plate is fixedly provided with a convex ring that matches the annular groove. The convex ring is rotatably disposed inside the annular groove.

[0009] The outer side of the buckle support plate has a circular array of protrusions, and the protrusions and the buckle support plate are an integral structure.

[0010] The threaded sleeve is uniformly provided with anti-slip ridges on its outer side, and the anti-slip ridges are integral with the threaded sleeve.

[0011] A stop block is fixedly installed at the bottom of the L-shaped fastener at the end opposite to the buckle support plate.

[0012] The stop block has rounded corners on both sides of its ends.

[0013] The connecting end on the connecting handle retracts inward.

[0014] The locking hole is a rectangular through hole that matches the L-shaped fastener.

[0015] Scaffolding, including the anti-loosening connection mechanism as described in any of the preceding items.

[0016] The beneficial effects of the present invention are as follows: In the present invention, the connecting end of the connecting handle passes through the buckle plate through the insertion hole. The L-shaped fastener in the buckle assembly enters the interior of the locking hole to stop the connecting handle and prevent it from coming off the buckle plate. At the same time, the pull-down assembly pulls the buckle assembly downward, so that the buckle assembly and the locking hole are locked together, preventing the pull-down assembly from coming off the locking hole. When subjected to vibration and impact, the connecting handle is not easy to come off the buckle plate, thus improving the connection stability and safety. Attached Figure Description

[0023] Various exemplary embodiments of the invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the invention or its application or use. The invention can be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the invention thorough and complete, and to fully express the scope of the invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, without excluding the possibility of encompassing other elements. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] like Figures 1 to 6 As shown, the anti-loosening connection mechanism includes a vertical rod 1 and a horizontal rod 2. A buckle plate 3 is fixedly installed on the vertical rod 1. The buckle plate 3 is fitted on the outside of the vertical rod 1 and connected to the vertical rod 1 by welding to form an integral structure. Four insertion holes 31 are evenly arranged on the buckle plate 3. The end of the horizontal rod 2 is provided with a connecting handle 4 that matches the insertion holes 31. The bottom of the connecting handle 4 is provided with a connecting end 41. A locking hole 42 is provided through the side of the connecting end 41. A pull-down assembly 6 is threadedly connected to the vertical rod 1 below the buckle plate 3. A buckle assembly 5 is rotatably installed on the top of the pull-down assembly 6 and fitted on the outside of the vertical rod 1. The buckle assembly 5 has an L-shaped fastener 52 that matches the locking hole 42.

[0026] In this embodiment, the connecting end 41 of the connecting handle 4 passes through the buckle plate 3 through the insertion hole 31. The L-shaped fastener 52 in the buckle assembly 5 enters the interior of the locking hole 42 to stop the connecting handle 4 and prevent the connecting handle 4 from coming off the inside of the buckle plate 3. At the same time, the pull-down assembly 6 pulls the buckle assembly 5 down to lock the buckle assembly 5 and the locking hole 42 together, preventing the pull-down assembly 6 from coming off the locking hole 42. This prevents the connecting handle 4 from coming off the buckle plate 3. When subjected to vibration and impact, the connecting handle 4 is not easy to come off the buckle plate 3, thus improving the connection stability and safety.

[0027] In some embodiments, as a specific implementation of the pull-down assembly 6, the pull-down assembly 6 has a threaded sleeve 61. The threaded sleeve 61 has an internal thread, and the outside of the upright 1 below the buckle 3 has an external thread that matches the internal thread. The threaded sleeve 61 is threadedly fitted to the outside of the pull rod 1. By screwing the threaded sleeve 61, the threaded sleeve 61 can be driven to move up and down along the axial direction of the upright 1 through the threaded structure between the threaded sleeve 61 and the upright 1, thereby tightening or releasing the buckle assembly 5. A buckle support plate 51 is rotatably provided on the top of the threaded sleeve 61. The top of the buckle support plate 51 has four L-shaped fasteners 52 arranged in a circumferential array. The L-shaped fasteners 52 are welded and fixed to the top of the buckle support plate 51, or are integrally formed with the buckle support plate 51 by casting, which has high connection strength. The buckle support plate 51 can apply a large downward pulling force to the L-shaped fasteners 52, thereby ensuring the stability of the connection.

[0028] In some embodiments, as a rotatable connection between the threaded sleeve 61 and the snap-fit ​​support plate 51, an annular groove 63 is provided on the inner side of the upper end of the threaded sleeve 61, and a convex ring 56 matching the annular groove 63 is fixedly provided on the bottom of the snap-fit ​​support plate 51. The convex ring 56 is rotatably disposed inside the annular groove 63, and the snap-fit ​​support plate 51 is rotatably disposed inside the annular groove 63 of the threaded sleeve 61 through the convex ring 56, so that the snap-fit ​​support plate 51 can be kept stationary when the threaded sleeve 61 is rotated.

[0029] In some embodiments, the outer side of the snap-on support plate 51 has a circumferential array of protrusions 55. The protrusions 55 and the snap-on support plate 51 are an integral structure. The protrusions 55 facilitate the rotation of the snap-on support plate 51 so as to insert the L-shaped fastener 52 into the locking hole 42 or to pull the L-shaped fastener 52 out of the locking hole 42.

[0030] In some embodiments, anti-slip ridges 62 are uniformly provided on the outer side of the threaded sleeve 61. The anti-slip ridges 62 are integral with the threaded sleeve 61. The anti-slip ridges 62 can increase the friction between the operator's hand and the threaded sleeve 61 when the operator holds the threaded sleeve 61 and rotates it.

[0031] In some embodiments, a stop block 54 is fixedly provided at the bottom of one end of the L-shaped fastener 52 away from the buckle support plate 51. When the pull-down assembly 6 pulls the L-shaped fastener 52 down, the stop block 54 blocks the outer edge of the locking hole 42, thereby preventing the L-shaped fastener 52 from coming out of the locking hole 42, thus ensuring the stability of the connection.

[0032] In some embodiments, both ends of the stop block 54 are provided with rounded corners 53. The rounded corners 53 on both ends of the stop block 54 make it easy to insert the L-shaped fastener 52 and the stop block 54 into the locking hole 42.

[0033] In some embodiments, the connecting end 41 on the connecting handle 4 retracts inward to facilitate the insertion of the connecting handle 4 into the interior of the socket 31.

[0034] In some embodiments, the locking hole 42 is a rectangular through hole that matches the L-shaped fastener 52.

[0035] In some embodiments, a scaffolding is disclosed, including an anti-loosening connection mechanism as described in any of the preceding embodiments.

[0036] The various embodiments of the present invention have now been described in detail. To avoid obscuring the concept of the invention, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solutions disclosed herein based on the above description.

[0037] The embodiments described above only illustrate some implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
