Description

Technical Field

[0001] The utility model relates to the technical field of cup-shaped steel support nuts, in particular to a cup-shaped steel support nut with adjustable length. Background Art

[0002] The cup-shaped steel support nut is a special nut used for installing cup-shaped steel supports. Cup-shaped steel supports are usually used in construction sites and other places to support concrete formworks or other structures. This type of nut is designed to cooperate with the threaded rod of the cup-shaped steel support to provide an adjustable support height. The patent with publication number CN210950459U discloses a cup-shaped steel support nut with variable length, which includes a steel support body, a fixed nut and a movable nut. First bolt holes are respectively arranged on both sides of the outer surface of the steel support body near the top edge. A connecting groove is welded at the bottom of the fixed nut, and the inside of the connecting groove is slidably embedded with the top of the steel support body. When using this cup-shaped steel support nut with variable length, the fixed nut is fixedly connected to the steel support body, the extension pipe is sequentially inserted into the movable nut and the fixed nut, and then the insertion rod is inserted into the insertion rod through hole to connect the movable nut and the fixed nut. The overall height of the device can be changed by simultaneously rotating the movable nut and the extension pipe. However, this cup-shaped steel support nut cannot adjust the length of the handle on the surface of the cup-shaped nut. In some narrow gap support places, the too-long handle may make it difficult to rotate the cup-shaped nut, which needs to be improved. Summary of the Utility Model

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: an adjustable-length cup-shaped steel support nut, including a sleeve rod 1 with threads provided on its surface. The threads provided on the surface of the sleeve rod 1 are engaged with the threads inside the cup-shaped nut 4. A top rod 2 is slidably connected inside the sleeve rod 1. A positioning hole 3 is provided inside the top rod 2, and a pin 14 is inserted into the positioning hole 3. A cup-shaped nut 4 is threadedly connected to the surface of the sleeve rod 1. A receiving groove 13 is provided inside the cup-shaped nut 4. A cushion ring 5 is sleeved on the surface of the sleeve rod 1. By rotating the cup-shaped nut 4, the cushion ring 5 is driven to slide upward under the action of the threads, thereby driving the cushion ring 5 to abut against the bottom end of the pin 14 to prevent the top rod 2 from falling. A convex block 6 is fixedly installed inside the receiving groove 13. A sliding rod 7 is fixedly installed at the bottom end of the convex block 6. A slider 8 is slidably connected to the surface of the sliding rod 7. The slider 8 is slidably connected to the receiving groove 13. A spring 9 is sleeved on the surface of the sliding rod 7. One end of the spring 9 is fixedly installed on the surface of the sliding rod 7, and the other end of the spring 9 is fixedly installed at the bottom end of the slider 8. A connecting plate 10 is rotatably connected to the surface of the slider 8. The connecting plate 10 is slidably connected to the receiving groove 13. A connecting plate 11 is rotatably connected inside the connecting plate 10. A pull handle 12 is fixedly installed on the surface of the connecting plate 11. After releasing the pull handle 12, the spring 9 drives the slider 8 to slide upward along the sliding rod 7, and at the same time drives the connecting plate 10 to change its angle, and then the connecting plate 11 and the pull handle 12 are received into the receiving groove 13.

[0024] Embodiment 2

[0025] Please refer to Figure 2 , 5 , a rotating frame 15 is rotatably connected inside the pin 14. A connecting rod 16 is fixedly installed on the surface of the rotating frame 15. An anti-detachment sleeve 17 is fixedly installed on the surface of the connecting rod 16. The anti-detachment sleeve 17 is sleeved on the surface of the pin 14. The pin 14 is inserted into the positioning hole 3 close to the top end of the sleeve rod 1. Then, the connecting rod 16 is rotated along the rotating frame 15, and the anti-detachment sleeve 17 is slightly bent to sleeve it on the surface of the pin 14. At this time, the anti-detachment work of the pin 14 is completed.

[0026] Working principle: During operation, first fix the sleeve rod 1 to the ground. Then pull the top rod 2 and make it abut against the part to be supported. Next, insert the pin 14 into the positioning hole 3 close to the top end of the sleeve rod 1. Then rotate the connecting rod 16 along the rotating frame 15 and slightly bend the anti-disengagement sleeve 17 to make it sleeved on the surface of the pin 14. At this time, the anti-disengagement work of the pin 14 is completed. Then, pull the handle 12 outward to an appropriate length according to the space size where the cup nut 4 is located. During this process, the handle 12 and the connecting plate 11 will move out from the inside of the storage groove 13, and at the same time drive the slider 8 to slide inward along the slide rod 7, driving the connecting plate 10 to change its angle and compress the spring 9. Then rotate the cup nut 4 and drive the gasket 5 to slide upward under the action of the thread, so as to drive the gasket 5 to abut against the bottom end of the pin 14 to prevent the top rod 2 from falling. Then release the handle 12. At this time, the spring 9 will drive the slider 8 to slide upward along the slide rod 7 and reset, and at the same time drive the connecting plate 10 to change its angle, and then the connecting plate 11 and the handle 12 will be received into the storage groove 13. At this time, the automatic storage work of the handle 12 is completed.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
