Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a drilling tool for wooden formwork. Background Technology

[0002] During construction, when the main structural type is a frame structure, 12mm thick bamboo plywood is generally used as formwork for beams and slabs. Since pre-embedded pipelines and structural beam formwork reinforcement both require drilling holes in the beam and slab formwork, the drilling process must minimize damage to the formwork. Traditional drilling methods use electric pistol drills, which produce regular, aesthetically pleasing holes at a fast speed with minimal damage. However, in actual construction, drilling workers using electric pistol drills need to run cables to connect them to power. Furthermore, the complex and varied construction environment, coupled with the weight of the electric pistol drills, makes manual movement on the formwork difficult. Additionally, the limited number of pre-embedded pipelines and structural beam formwork reinforcements results in low usage frequency, with most of the time spent on cable connection and equipment movement, impacting construction progress. Utility Model Content

[0003] The purpose of this utility model is to provide a simple and easy-to-transfer wooden template drilling tool.

[0004] This utility model is achieved through the following measures: a wooden template drilling tool, characterized in that it includes a rotating shaft, the rotating shaft including a long shaft section and a short shaft section arranged concentrically, the long shaft section and the short shaft section being connected by a U-shaped handle;

[0005] A drill bit is fixedly installed below the long shaft section, and a top ring is rotatably installed at the upper end of the short shaft section via a bearing.

[0006] A hand-held handle is provided above the top ring, and the two ends of the hand-held handle are fixed to the side wall of the top ring by connecting rods.

[0007] When in use, place the drill bit directly against the wooden template, press down the handle with one hand, and rotate the U-shaped handle with the other hand. The drill bit will drill a hole in the wooden template during the rotation process.

[0008] It also includes a support, which includes a horizontal plate, vertical plates symmetrically arranged at both ends of the horizontal plate, and a foot plate fixedly arranged on the outside of the vertical plate. The horizontal plate is provided with a through hole that allows the drill bit to pass through, and the horizontal plate is sleeved on the outside of the drill bit.

[0009] An adjusting plate is provided above the horizontal plate. The adjusting plate is rotatably mounted on the lower part of the long shaft section via a bearing. Several guide posts are provided on the horizontal plate. The adjusting plate is sleeved on the guide posts. A spring is sleeved on the guide posts. The upper end of the spring is fixed on the adjusting plate, and the lower end is fixed on the horizontal plate.

[0010] The lower end face of the drill bit is slightly higher than the lower end face of the foot pedal.

[0011] The horizontal plate is positioned outside the drill bit, with the lower end of the drill bit slightly higher than the lower end of the foot plate. This protects the drill bit and prevents damage from impacts during movement. Additionally, workers can step on the foot plate during drilling to further stabilize the drill bit. Since the drill bit rotates during drilling, a bearing is also installed on the long shaft section to improve the smoothness of shaft rotation.

[0012] The adjusting plate is spring-loaded onto the horizontal plate. Before drilling, the operator can step on the footplate and press the rotating shaft to bring the bottom of the drill bit into contact with the template. This allows the operator to observe the drill bit's position relative to the pre-set point and confirm it is correct before drilling. Because the foot is on the footplate, the drill bit's position remains unchanged even if it disengages from the template.

[0013] The upper ends of all the guide posts are connected by a fixing plate. The fixing plate is sleeved on the outside of the long shaft section and is provided with a sleeve concentric with the long shaft section. The inner diameter of the sleeve is larger than the outer diameter of the long shaft section. The inner wall of the sleeve has an internal thread. A circular boss is provided on the long shaft section and above the sleeve. The circular boss is provided with an external thread that mates with the internal thread.

[0014] When drilling, if the worker cannot penetrate the template in one go, the drill bit needs to be aligned a second time. Therefore, through the cooperation of the threaded sleeve and the threaded boss, the position of the drill bit and the support can remain unchanged during the drilling process, even if the rotating shaft stops rotating, that is, the drill bit remains on the template.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment are: simple structure, easy operation and convenient transfer. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0023] See Figures 1-4 A tool for drilling holes in wooden templates, characterized in that it includes a rotating shaft 1, the rotating shaft 1 including a long shaft section 101 and a short shaft section 102 arranged concentrically, the long shaft section 101 and the short shaft section 102 being connected by a U-shaped handle 103;

[0024] A drill bit 13 is fixedly installed below the long shaft section 101, and a top ring 2 is rotatably installed at the upper end of the short shaft section 102 via a bearing 4.

[0025] A hand-held lever 3 is provided above the top ring 2, and the two ends of the hand-held lever 3 are fixed to the side wall of the top ring 2 by connecting rods.

[0026] When using, place the drill bit 13 directly against the wooden template, press down the handle 3 with one hand, and rotate the U-shaped handle 103 with the other hand. The drill bit 13 will drill holes in the wooden template during the rotation process.

[0027] It also includes a bracket 5, which includes a horizontal plate 501, vertical plates 502 symmetrically arranged at both ends of the horizontal plate 501, and a foot plate 503 fixedly arranged on the outside of the vertical plate 502. The horizontal plate 501 is provided with a through hole that allows the drill bit 13 to pass through, and the horizontal plate 501 is sleeved on the outside of the drill bit 13.

[0028] An adjusting plate 6 is provided above the horizontal plate 501. The adjusting plate 6 is rotatably set at the lower part of the long shaft section 101 via the bearing 7. Several guide posts 8 are provided on the horizontal plate 501. The adjusting plate 6 is sleeved on the guide posts 8. A spring 9 is sleeved on the guide posts 8. The upper end of the spring 9 is fixed on the adjusting plate 6, and the lower end is fixed on the horizontal plate 501.

[0029] The lower end face of drill bit 13 is slightly higher than the lower end face of foot pedal 503.

[0030] A horizontal plate 501 is positioned outside the drill bit 13, with the lower end face of the drill bit 13 slightly higher than the lower end face of the foot plate 503. This protects the drill bit 13 from damage caused by collisions during movement. Additionally, during drilling, workers can step on the foot plate 503 to further stabilize the drill bit 13. Since the drill bit 13 needs to rotate during drilling, a bearing is also installed in the long shaft section 101 to increase the smoothness of the shaft 1's rotation.

[0031] The adjusting plate 6 is mounted on the horizontal plate 501 via a spring 9. This allows the operator to step on the foot pedal 503 before drilling, and then press the rotating shaft 1 to bring the bottom of the drill bit 13 into contact with the template. The operator can then observe the position of the drill bit 13 relative to the pre-reserved point and confirm that drilling is proceeding only after confirming that everything is correct. Because the foot is on the foot pedal 503, even if the drill bit 13 is disengaged from the template, its position remains unchanged.

[0032] The upper ends of all guide posts 8 are connected by a fixing plate 10. The fixing plate 10 is sleeved on the outside of the long shaft section 101 and is provided with a sleeve 11 concentric with the long shaft section 101. The inner diameter of the sleeve 11 is larger than the outer diameter of the long shaft section 101. The inner wall of the sleeve 11 has an internal thread. A circular boss 12 is provided on the long shaft section 101 and above the sleeve 11. The circular boss 12 is provided with an external thread that mates with the internal thread.

[0033] When drilling, if the worker cannot penetrate the template in one go, it is necessary to align the drill bit 13 a second time.

[0034] The engagement between the threaded sleeve 11 and the threaded boss allows the drill bit 13 to remain in the same position as the support 5 even if the rotating shaft 1 stops rotating during the drilling process; that is, the drill bit 13 remains on the template.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
