Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a screw hole cleaning device. Background Technique

[0002] In construction engineering, various buildings need to support formwork for the wall during the main structure construction. After the formwork is removed, many screw holes will be generated. In addition, after the connection members of the external scaffolding are removed, screw holes will also be left on the wall. After the entire construction is completed, the screw holes need to be blocked. However, before blocking, the screw holes need to be cleaned in advance to avoid problems such as incomplete blocking of the screw holes and subsequent water leakage due to insufficient cleaning of the screw holes.

[0003] After retrieval, in a building construction hole treatment device with the patent publication number CN217480886U, it is proposed that "through the setting of the cleaning mechanism, the flowing air enters the first holding cylinder, so that the fan blade drives the rotating rod and the connecting column to rotate simultaneously. Then, the staff inserts the cleaning brush cylinder into the screw hole, so that the continuously rotating cleaning brush cylinder continuously cleans the inside of the screw hole, and the flowing air continuously blows out the debris inside the screw hole, thereby avoiding the situation that there is too much debris in the screw hole and affecting the mortar filling".

[0004] However, the above solution still has certain deficiencies in actual use. This solution inserts the holding cylinder into the screw hole and cooperates with the rotation of the cleaning brush to clean the inside of the screw hole. However, since the inner diameter specifications of the screw holes are different, but the holding cylinder cannot change its own size, it causes the staff to hold the holding cylinder for a long time when inserting it into the screw hole, and manual operation will greatly reduce the cleaning effect and cleaning efficiency.

[0024] The cleaning structure 3 includes a driving cylinder 301, a placing plate 302 is fixedly installed on the inner wall of the driving cylinder 301, a driving rotating shaft 303 and a second electric push rod 304 are respectively arranged at the bottom end and the top end of the placing plate 302, a cleaning brush 305 is movably sleeved at the movable end of the driving rotating shaft 303, a bent rod 306 is fixedly installed at the movable end of the second electric push rod 304, and one end of the bent rod 306 far away from the second electric push rod 304 is slidably connected to the surface of the cleaning brush 305.

[0025] By setting the cleaning structure 3, the driving rotating shaft 303 inside the driving cylinder 301 can drive the cleaning brush 305 to continuously clean the inside of the screw hole, and then cooperating with the second electric push rod 304, the second electric push rod 304 can drive the cleaning brush 305 to perform a horizontal movement while rotating through the bent rod 306 and the annular groove 308 on the surface of the cleaning brush 305, so that the cleaning brush 305 can clean different positions inside the screw hole, thereby further improving the cleaning effect.

[0026] Specifically, an anti-slip pad is arranged on the side of the lapping strip 207 far away from the resisting block 205, and the anti-slip pad is a soft silicone grease pad.

[0027] In this implementation, the use of the anti-slip pad can improve the lapping effect between the lapping strip 207 and the inner wall of the screw hole.

[0028] Specifically, a central hole 307 is provided in the center of the cleaning brush 305. A cross bar is fixedly installed on the inner wall of the central hole 307. The driving rotating shaft 303 is slidably connected to the central hole 307 of the cleaning brush 305 through the cross bar. An annular groove 308 is provided on the surface of the cleaning brush 305. One end of the bent rod 306 away from the second electric push rod 304 extends to the inner wall of the annular groove 308 and lapps with the inner wall of the annular groove 308.

[0029] In this implementation, the output shaft of the driving rotating shaft 303 is movably connected to the central hole 307 through a cross bar. Therefore, the cleaning brush 305 can perform horizontal sliding while rotating, thereby completing the adjustment of the total length of the cleaning brush 305 and the driving cylinder 301, enabling the cleaning brush 305 to penetrate into the screw hole for cleaning.

[0030] During use, when the user needs to clean the opening position of the screw hole, only need to hold the device and start the cleaning structure 3 through the built-in motor, so that the output shaft of the driving rotating shaft 303 included in the cleaning structure 3 drives the cleaning brush 305 to rotate through the central hole 307.

[0031] When the staff's hand cannot reach the deep part of the screw hole, the device can be placed inside the screw hole, and then the fixing structure 2 is started through the built-in battery 102, so that the movable end of the first electric push rod 202 drives the pushing cone 203 to slide backward along the length direction of the clamping cylinder 201, so that the pushing cone 203 will gradually contact the abutting block 205 during the movement, prompting the abutting block 205 to slide along the slope of the pushing cone 203, so that the abutting block 205 drives the lapping strip 207 to extend towards the outside of the clamping cylinder 201, so that the lapping strip 207 gradually extends out of the outside of the clamping cylinder 201, causing the clamping cylinder 201 to lap with the inner wall of the screw hole through the lapping strip 207, enabling the device to be automatically assembled into the inner wall of the screw hole.

[0032] When it is necessary to adjust the total length of the cleaning brush 305 and the driving cylinder 301, the second electric push rod 304 is started through the built-in battery 102, so that the movable end of the second electric push rod 304 drives the bent rod 306 to slide, so that the bent rod 306 drives the cleaning brush 305 to perform synchronous displacement through the annular groove 308.

[0033] During this process, the output shaft of the driving rotating shaft 303 is movably connected to the central hole 307 through a cross bar. Therefore, the cleaning brush 305 can perform horizontal sliding while rotating, thereby completing the adjustment of the total length of the cleaning brush 305 and the driving cylinder 301, enabling the cleaning brush 305 to penetrate into the inside of the screw hole for cleaning.

[0034] In summary, for this screw hole cleaning device, by setting the fixing structure 2, the first electric push rod 202 inside the clamping cylinder 201 drives the pushing cone 203 to slide on the inner wall of the clamping cylinder 201. During the movement of the pushing cone 203, the abutting block 205 drives the overlapping strip 207 to extend towards the outside of the clamping cylinder 201, causing the overlapping strip 207 to gradually extend out of the outside of the clamping cylinder 201. As a result, the clamping cylinder 201 can be lapped with the inner wall of the screw hole through the overlapping strip 207, enabling the device to be automatically assembled inside the inner wall of the screw hole, avoiding the problem that the device needs to be held by the staff for a long time during use, and making the use of the device time-saving and labor-saving.

[0035] By setting the cleaning structure 3, the driving rotating shaft 303 inside the driving cylinder 301 can drive the cleaning brush 305 to continuously clean the inside of the screw hole. In cooperation with the second electric push rod 304, the cleaning brush 305 can be driven to perform horizontal movement while rotating through the bending rod 306 and the annular groove 308 on the surface of the cleaning brush 305, enabling the cleaning brush 305 to clean different positions inside the screw hole, thereby further improving the cleaning effect.

[0036] 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.
