[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a device for drilling holes for rebar anchoring at the bottom of beams. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The beam bottom rebar drilling device includes a drilling machine body 1, and an angle adjustment mechanism 2 is provided on the surface of the drilling machine body 1.

[0028] The angle adjustment mechanism 2 includes a ratchet 201, which is fixedly connected to the surface of the drilling machine body 1. A groove 204 is provided on the top of the ratchet 201, and two movable blocks 202 are provided on the top of the ratchet 201. A slider 205 is fixedly connected to the bottom of each of the two movable blocks 202, and the surface of the slider 205 contacts the inner wall of the groove 204. A multi-stage cylinder 203 is fixedly installed on the bottom of each of the two movable blocks 202. A support rod 206 is fixedly connected to one end of the multi-stage cylinder 203, and a universal ball 207 is fixedly connected to one end of the support rod 206. The surface of the universal ball 207 rotates... A positioning cone 208 is attached, and a connecting rod 209 is provided at the bottom of the positioning cone 208. A multi-section suction cup 210 is fixedly connected to the bottom of the connecting rod 209. By setting an angle adjustment mechanism 2, the drilling point can be positioned to adapt to different drilling needs. The multi-section suction cup 210 prevents the drilling machine body 1 from shifting due to external torque or gravity, and the multi-section suction cup 210 will not damage the surface of the wall. Furthermore, the universal ball 207 allows the angle of the drilling machine body 1 to be adjusted without moving the position of the drilling machine body 1, improving flexibility and enabling efficient completion of drilling tasks, thus improving work efficiency.

[0029] Reference Figure 2 The surface of the drilling machine body 1 is provided with a protective shell 3, and the bottom of the protective shell 3 is provided with a slot 4. Both multi-section cylinders 203 penetrate into the inner wall of the slot 4. By providing the protective shell 3, it is possible to prevent the flying gravel and dust during drilling from entering the interior of the protective shell 3 and to prevent the internal parts of the protective shell 3 from getting stuck. The slot 4 can provide movement space for the multi-section cylinders 203.

[0030] Reference Figure 2 and Figure 3 The inner wall of the protective shell 3 is fixedly connected with four fixing rods 5. All four fixing rods 5 penetrate into the inner wall of the ratchet 201. By setting the fixing rods 5, the protective shell 3 can be fixed to prevent the multi-section cylinder 203 and the moving block 202 from being blocked when moving.

[0031] Reference Figure 4 The bottom of each of the two movable blocks 202 is rotatably connected to a rotating shaft 7, and a pawl 6 is fixedly connected to the surface of the rotating shaft 7. The pawl 6 works in conjunction with the ratchet 201. The bottom of each of the two movable blocks 202 is fixedly connected to a limiting block 8, and an elastic piece 9 is fixedly connected to one side of the limiting block 8. The elastic piece 9 works in conjunction with the pawl 6. By setting the rotating shaft 7, pawl 6, elastic piece 9 and limiting block 8, the moved multi-section cylinder 203 can be limited to prevent the fixed multi-section cylinder 203 from shifting. The movable block 202 can be fixed by the meshing of the pawl 6 and the ratchet 201.

[0032] Reference Figure 5The bottom of the slider 205 is rotatably connected to a ball bearing 10. The surface of the ball bearing 10 contacts the inner wall of the groove 204. By setting the ball bearing 10, the friction between the slider 205 and the groove 204 can be reduced, making the slider 205 move more smoothly.

[0033] Reference Figure 7 The bottom of the positioning cone 208 is provided with a threaded groove 11. The positioning cone 208 and the connecting rod 209 are threadedly connected through the threaded groove 11. By setting the threaded groove 11, the user can easily replace the multi-section suction cup 210 through the threaded groove 11, which improves convenience.

[0034] Reference Figure 8 The top of the protective shell 3 has a groove 12, and a strap 13 is fixedly connected inside the groove 12. The strap 13 is used in conjunction with the multi-section cylinder 203. By setting the strap 13, it is convenient for the user to fix the two multi-section cylinders 203 to the idle drilling machine body 1 through the strap 13 for easy storage.

[0035] Working principle: When the user needs to drill at an angle to the marked points using the drill body 1, the user adjusts the position of the two multi-section cylinders 203 by rotating the multi-section cylinder 203. When the multi-section cylinders 203 and the moving block 202 move simultaneously, the slide groove 204 limits the slider 205, allowing the slider 205, the moving block 202, and the multi-section cylinders 203 to move along the path of the slide groove 204. The ball bearing 10 reduces the friction between the slide groove 204 and the slider 205. When the multi-stage cylinder 203 rotates, the pawl 6 moves along the surface of the ratchet 201. When the multi-stage cylinder 203 is adjusted to a suitable angle, the pawl 6 engages with the ratchet 201, thereby limiting the movement block 202. The surface of the elastic plate 9 contacts the surface of the pawl 6, and the elastic plate 9 can limit the pawl 6 to prevent it from disengaging from the ratchet 201. The user uses external equipment to clean the dust, debris, and other impurities from the surface of the beam bottom. Cleaning the surface of the beam bottom is to ensure the multi-stage suction... The disc 210 fits tightly, preventing dust from affecting the adsorption effect of the multi-section suction cup 210. By repeatedly pressing the multi-section suction cup 210, the air inside the multi-section suction cup 210 is gradually expelled. When the air inside the multi-section suction cup 210 is fully expelled, a vacuum state is formed between the multi-section suction cup 210 and the bottom surface of the beam. The vacuum state allows the multi-section suction cup 210 to adhere to the bottom surface of the beam, providing a certain degree of support and fixation. Then, by manually adjusting the angle of the drilling machine body 1, the support rod 206... The multi-stage cylinder 203 is connected to the universal ball 207. When the drilling machine body 1 is adjusted, the universal ball 207 will rotate inside the positioning cone 208. A damping sleeve is installed inside the positioning cone 208. The damping sleeve can increase the friction and provide resistance to prevent the universal ball 207 from continuing to rotate due to inertia or external force after adjustment, ensuring that the universal ball 207 is kept in the set position. This makes it convenient for the user to adjust the angle of the drilling machine body 1, while avoiding the drilling machine body 1 from deviating, and facilitating drilling.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
