Description

Technical Field

[0001] The utility model relates to the technical field of the construction industry, and particularly relates to a transverse bar of a socketed scaffolding with adjustable length. Background Art

[0002] The socketed scaffolding is a commonly used supporting structure in the construction and decoration industries, mainly used to provide a stable platform for workers to perform high-altitude operations.

[0003] Firstly, the traditional transverse bar with a fixed length cannot be adjusted according to actual needs. The construction party needs to prepare transverse bars of various specifications in different construction environments. Moreover, since the length of the transverse bar of the scaffolding cannot flexibly adapt to different building requirements, it may cause material waste.

[0004] Secondly, if the transverse bar cannot be stably fixed after extension, it will shake or move with the load or the activities of workers, resulting in the instability of the overall structure of the scaffolding, thereby increasing the safety risk.

[0005] Finally, on a construction site, there are often substances such as mortar, concrete, sand and gravel at the construction site. If the transverse bar accidentally adheres to these materials but has no cleaning function, the adhesions will gradually accumulate, which will affect the adjustability of the transverse bar, making it difficult to operate smoothly, and will cause wear and corrosion of the transverse bar, resulting in a shortened service life of the transverse bar and increasing the long-term maintenance and replacement costs.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-5 , an adjustable - length transverse bar of a disc - type fastener scaffold, including an extension mechanism, an auxiliary mechanism and a fixing mechanism. The extension mechanism includes a first crossbar 1, a second crossbar 2, an extension rod 3 and an end head 4. One end of the first crossbar 1 is rotatably connected to the extension rod 3, one end of the second crossbar 2 is rotatably connected to the extension rod 3, and end heads 4 are arranged on the first crossbar 1 and the second crossbar 2. The auxiliary mechanism includes a clamping rod 5, a fixed block 6, a cleaning sleeve 7 and a force - borrowing sleeve 8. The clamping rod 5 is installed inside the end head 4 and is slidably connected to the end head 4. The fixed block 6 is installed on the end head 4 and is rotatably connected to the end head 4. The cleaning sleeve 7 is slidably connected to the force - borrowing sleeve 8, and the force - borrowing sleeve 8 is slidably connected to the second crossbar 2.

[0032] In this embodiment, the extension mechanism includes a first crossbar 1, a second crossbar 2, an extension rod 3 and an end head 4. During use, unlock the fixing mechanism, and then according to the length of the scaffold, extend the length of the extension rod 3 between the first crossbar 1 and the second crossbar 2. At this time, when the first crossbar 1 is pulled, the connecting block 16 on the extension rod 3 slides in the connecting groove 17 in the second crossbar 2. Due to the shape of the connecting groove 17, while the extension rod 3 slides, the other end rotates in the square block 14 at one end of the first crossbar 1. And as the extension rod 3 extends, the protection sleeve 15 is also pulled accordingly, so as to protect the extension rod 3 from being invaded by external materials such as sand, slurry and other materials.

[0033] In this embodiment, the auxiliary mechanism includes a clamping rod 5, a fixing block 6, a cleaning sleeve 7, and a force - borrowing sleeve 8. When in use, when the ends 4 on the first cross - bar 1 and the second cross - bar 2 are placed on the disk buckle, take out the fixing block 6 at this time. At this time, the clamping rod 5 is no longer squeezed. Hold the clamping rod 5 and swing the clamping rod 5 so that the second through - rod 19 can slide in the second chute 24 on the clamping rod 5, so that the clamping rod 5 can clamp the end 4 and the disk buckle to connect and fix them. After the end 4 is fixed on the disk buckle, pull the force - borrowing sleeve 8 so that the limiting block 26 on the force - borrowing sleeve 8 can slide in the limiting groove 25 of the protection sleeve 15. In order to prevent sand and slurry from falling onto the second cross - bar 2 during the operation of the cross - bar and blocking the retraction of the extension rod 3, at this time, you can grasp the anti - slip layer 27 on the force - borrowing sleeve 8 and then rotate the force - borrowing sleeve 8 so that the limiting block 26 on the force - borrowing sleeve 8 can disengage from the limiting groove 25. After the force - borrowing sleeve 8 disengages from the limiting groove 25, slide the force - borrowing sleeve 8 at this time so that the force - borrowing sleeve 8 impacts the cleaning sleeve 7. While the cleaning sleeve 7 moves on the second cross - bar 2, the cleaning blade 28 starts to clean the sand and slurry adhered to the second cross - bar 2, and under the impact of the force - borrowing sleeve 8, the impact pad 29 on the cleaning sleeve 7 buffers to reduce the tremor caused by the impact, so as to better protect the human body.

[0034] In this embodiment, the fixing mechanism includes a first spring 9, a second spring 10, a connecting rod 11, a pressing plate 12, and a fixing frame 13. When in use, directly press the pressing plate 12. At this time, the pressing plate 12 slides under the action of the first through - rod 18 and compresses the second spring 10. The connecting rod 11 is displaced by the pressing plate 12 and at the same time starts to change its position and pushes the fixing frame 13. The fixing frame 13 slides in the square block 14 at this time, and the sliding block 23 on the fixing frame 13 slides in the first chute 22 in the square block 14, so that the fixing frame 13 can operate normally. When the connecting rod 11 and the pressing plate 12 are horizontal, the fixing frame 13 disengages from the first clamping hole 20 at this time, so that the extension rod 3 can be retracted and extended. And during the process of the extension rod 3 retracting into the second cross - bar 2, the protection sleeve 15 slides directly on the second cross - bar 2. When the fixing frame 13 reaches the second clamping hole 21 on the second cross - bar 2, release the pressing plate 12 at this time, and the fixing frame 13 is fixed in the second clamping hole 21, thus completing the fixation of the second cross - bar 2 and the protection sleeve 15.

[0035] Embodiment 2:

[0036] In summary, during use, first unlock the fixing mechanism and directly press the pressing plate 12. At this time, the pressing plate 12 slides under the action of the first through rod 18 and compresses the second spring 10. The connecting rod 11 is displaced by the pressing plate 12, starts to change its position at the same time, and pushes the fixing frame 13. The fixing frame 13 slides in the square block 14 at this time, and the sliding block 23 on the fixing frame 13 slides in the first chute 22 in the square block 14, so that the fixing frame 13 can operate normally. When the connecting rod 11 and the pressing plate 12 are horizontal, the fixing frame 13 disengages from the first locking hole 20 at this time, so that the extension rod 3 can be retracted and extended. And when the extension rod 3 is retracted into the second cross bar 2, the protective sleeve 15 slides directly on the second cross bar 2 at this time. When the fixing frame 13 reaches the second locking hole 21 on the second cross bar 2, release the pressing plate 12 at this time, and the fixing frame 13 is fixed in the second locking hole 21, thus completing the fixation of the second cross bar 2 and the protective sleeve 15. After the fixing mechanism is unlocked as described above, install the cross bar at this time, and then extend the length of the extension rod 3 between the first cross bar 1 and the second cross bar 2 according to the length of the scaffolding. At this time, the first cross bar 1 is pulled, and the connecting block 16 on the extension rod 3 slides in the connecting groove 17 in the second cross bar 2. Due to the shape of the connecting groove 17, while the extension rod 3 slides, the other end rotates in the square block 14 at one end of the first cross bar 1, and as the extension rod 3 extends, the protective sleeve 15 is also pulled, so as to protect the extension rod 3 from being invaded by external materials such as sand, slurry and other materials. After installing on the disc buckle, fix the disc buckle and the cross bar at this time. Take out the fixing block 6. At this time, the clamping rod 5 is no longer squeezed. Hold the clamping rod 5 and swing the clamping rod 5 so that the second through rod 19 can slide in the second chute 24 on the clamping rod 5, so that the clamping rod 5 can clamp the end head 4 and the disc buckle to connect and fix them. After the end head 4 is fixed on the disc buckle, pull the force borrowing sleeve 8 so that the limiting block 26 on the force borrowing sleeve 8 can slide in the limiting groove 25 of the protective sleeve 15. In order to prevent sand and slurry from falling on the second cross bar 2 during the operation of the cross bar and blocking the retraction of the extension rod 3, at this time, the anti-slip layer 27 on the force borrowing sleeve 8 can be grasped, and then the force borrowing sleeve 8 is rotated so that the limiting block 26 on the force borrowing sleeve 8 can disengage from the limiting groove 25. When the force borrowing sleeve 8 disengages from the limiting groove 25, slide the force borrowing sleeve 8 at this time so that the force borrowing sleeve 8 impacts the cleaning sleeve 7, and while the cleaning sleeve 7 moves on the second cross bar 2, the cleaning blade 28 starts to clean the sand and slurry adhered to the second cross bar 2, and under the impact of the force borrowing sleeve 8, the impact pad 29 on the cleaning sleeve 7 buffers to reduce the tremor caused by the impact, so as to better protect the human body (in practical applications, the positions of the clamping rod 5, the second through rod 19, and the fixing block 6 can be opposite to the installation directions of the pressing plate 12 and the connecting rod 11, that is to say, the pressing plate 12 and the connecting rod 11 are facing the ground relative to the clamping rod 5 and the second through rod 19,This can prevent the fixing mechanism from being adhered to by sand, gravel and slurry on the construction site. In addition, the protective sleeve 15, the force-boosting sleeve 8 and the cleaning sleeve 7 can not only play their respective roles, but also provide support for the entire crossbar, thereby expanding the application scenarios of the crossbar).

[0037] Among all the solutions mentioned above, for the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated here one by one. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
