[0034] This utility model provides an outdoor construction warning tape retraction frame, whose main function is to facilitate easy disassembly and relocation through a modular, split structure, as well as to allow for quick replacement of damaged parts.
[0035] Reference Figure 1 and Figure 3 As shown, the outdoor construction warning tape retraction frame mainly includes a support, a reel, and a locking mechanism. The support consists of inclined support columns 2, a base bracket 1, a bearing seat 3, and a roller 4. The base bracket 1 has a U-shaped frame structure and is placed horizontally on the ground. Inclined support columns 2 are welded and fixed at both ends of the base bracket 1. The upper ends of the two inclined support columns 2 are close to each other, and a bearing seat 3 is welded and fixed between the upper ends of the two inclined support columns 2. The two inclined support columns 2 are in a V-shape, which can provide vertical support for the bearing seat 3. The roller 4 is interference-fitted into the bearing of the bearing seat 3 and is centered. The two ends of the roller 4 extend horizontally towards the front and rear of the bearing seat 3, respectively. The front end of the roller 4 has a radially arranged transmission groove 5. Multiple transmission grooves 5 are arranged along the circumference of the roller 4. The other end of the roller 4 has a channel 14 along the axial direction inside the cylinder cavity.
[0036] The central part of the take-up reel is fitted outside the front end of the roller 4, which has a transmission groove 5. The take-up reel is set on the same side as the base bracket 1. The take-up reel includes a ring frame 6 and support rods 7. The number and distribution of support rods 7 correspond to the number and position of the slots in the transmission grooves 5. Multiple support rods 7 are distributed along the circumference of the ring frame 6. The support rods 7 are L-shaped. One end of the support rod 7 is welded and fixed to the inner side of the ring frame 6. The other end of the support rod 7 extends to the center of the ring frame 6 and into the corresponding transmission groove 5. Then, it extends horizontally along the axial direction towards the end of the roller 4 pointing towards the take-up reel. The length of the horizontal section of the support rod 7 must exceed the length of the transmission groove 5. The purpose is to wrap the initial end of the warning tape around the horizontal section of the support rod 7, which has a pre-positioning effect on the warning tape so that the warning tape can be wound up and wrapped when the take-up reel rotates.
[0037] Furthermore, in this embodiment, as Figure 1 As shown, the length direction of the transmission groove 5 is consistent with the axial direction of the roller 4, and the rear end of the transmission groove 5 is not flush with the front side of the bearing seat 3, so as to avoid the support rod 7 from contacting the bearing seat 3 and generating frictional resistance.
[0038] The locking mechanism includes a rocker arm and a baffle 12. The rocker arm is mainly composed of three parts: a rotating section 8, a steering section 9, and a gripping section 10. One end of the rotating section 8, i.e. the front end, is provided with a threaded section, and the other end, i.e. the rear end, is welded and fixed perpendicularly to the steering section 9. The front end of the rotating section 8 passes through the center of the rear of the roller 4 and extends to the front of the horizontal section of the support rod 7 and is threadedly fitted with the center of the baffle 12. A limit ring 11 is welded and fitted to the rear end of the rotating section 8.
[0039] The upper end of the steering section 9 is welded perpendicularly to the rear end of the rotating section 8, and the lower end of the steering section 9 is welded to the front end of the gripping section 10. The rear end of the gripping section 10 is upset to facilitate the rotation of the sleeve 15 outside the gripping section 10. At the same time, the upset of the rear end of the gripping section 10 can prevent the sleeve 15 from falling off. The gripping sleeve 15 makes it easier for workers to rotate the rocker arm. The gripping section 10 and the rotating section 8 are set parallel to each other so that the overall shape of the rocker arm tends to be Z-shaped.
[0040] By using the threaded thrust to rotate the baffle 12, the rocker arm is gradually brought closer to the take-up reel, and finally comes into close contact with the front end of the horizontal section of the support rod 7, thus fixing the rocker arm and the take-up reel. At the same time, under the tightening action of the baffle 12, the limiting ring 11 is tightly attached to the rear end face of the roller 4. The front side of the limiting ring 11 has four transmission protrusions 13 distributed along the circumference of the rotating section 8. The transmission protrusions 13 extend along the axial direction of the rotating section 8. Correspondingly, a groove 14 is provided on the inner side of the rear end cavity of the roller 4 to meet the transmission protrusions 13. Thus, when the limiting ring 11 is tightly attached to the rear end face of the roller 4, the transmission protrusions 13 also enter the corresponding groove 14. Under this condition, by rotating the rocker arm, the roller 4 can be driven to rotate synchronously, thereby driving the take-up reel to rotate and take up the warning tape.
[0041] When winding up the warning tape, first wrap the initial end of the warning tape around the horizontal section of the support rod 7. Wrapping it several times can also pre-fix the initial end of the warning tape. Then, rotate the rocker arm to wind up the warning tape. When storing the winding rack, first rotate the baffle 12 in the opposite direction to remove it from the thread at the front end of the rotating section 8 of the rocker arm. Then, pull the rotating section 8 of the rocker arm out from the center of the roller 4. Finally, push the winding reel forward towards the roller 4 to remove the winding reel from the roller 4. The whole disassembly is convenient and quick. By disassembling the winding rack for storage, space is saved, and there is no need to worry about damage from collisions with other objects during transportation.
[0042] The rack provided in this embodiment has a split structure with a modular layout, which makes it easy to disassemble and move. It also allows for precise and quick replacement of damaged parts without the need for additional tools. Furthermore, the repair process will not damage other structural components, making it extremely convenient to operate and providing excellent performance.
[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
