Description

Technical Field

[0001] The utility model relates to the technical field of electric drill fixing brackets. More specifically, the utility model relates to an electric drill fixing bracket device for portable rotary bracket hole opening in a limited space. Background Technique

[0002] At present, the known structure of a hand-held electric drill bracket is composed of a cast iron base, a column, a height fixing device, a drilling depth operation handle, and a hand-held electric drill clamping device. When the bottom surface of the object to be drilled is a plane, it can be moved relatively conveniently for drilling operations;

[0003] However, when the item to be drilled is a pipeline, the pipeline is prone to roll and the drill bit is prone to slide during the drilling process, resulting in the deviation of the drilling position. And when drilling holes in a row, it is difficult to ensure that the pipeline only moves without rolling in the longitudinal direction, and the drilled holes cannot be in a row.

[0004] After retrieval, the Chinese patent with the authorization announcement number CN214920729U discloses a hand-held electric drill drilling fixing bracket device for pipeline prefabrication. Through the clamping assembly, the relative position of the clamping piece relative to the installation chute can be adjusted according to the user's needs, so as to clamp fixing components of workpieces of different sizes. And the workpiece fixing component includes a keel and a clamping piece. The clamping piece is detachably installed on the keel, and the keel is clamped between adjacent clamping pieces. Preferably, the clamping piece is a U-shaped bolt. The workpiece is fixed on the keel through the clamping piece to prevent the workpiece from rotating relative to the keel, keep the pipeline stable, ensure that the holes are in a row, and further can stably clamp easily rolling workpieces such as pipelines, keep the pipeline stable, ensure that the holes are in a row, improve the drilling quality, and has a simple structure, is convenient and practical;

[0005] However, when this structure is actually used, the operation is complex. When on a wall with a relatively narrow entrance and exit, it is difficult to move the rotary angle between the position of the hand-held electric drill clamping device and the base, resulting in the inability to operate flexibly in a limited space, and thus it is difficult to meet the user's need for precise drilling in various relatively narrow indoor operation spaces.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] The embodiments of the present application disclose an electric drill fixing device with a rotatable bracket opening for a portable confined space as Figures 1-5 shown, which includes a base clamp 1. A threaded groove 2 is formed on the surface of the base clamp 1. A threaded column 3 is threadedly connected inside the threaded groove 2. A rotating mechanism is rotatably connected to the top of the base clamp 1.

[0026] The rotating mechanism includes an electric telescopic rod 4 rotatably connected to the top of the base clamp 1. The output end of the electric telescopic rod 4 is fixedly provided with a rotating sleeve 5. The rotating sleeve 5 is sleeved on the surface of the electric telescopic rod 4. Two sleeves 6 are sleeved on the rotating sleeve 5. A plurality of threaded holes 7 are formed on the surface of the rotating sleeve 5. A fixing bolt 8 is threadedly connected inside the sleeve 6. The fixing bolt 8 is threadedly connected to the threaded hole 7. Hold the operating cross bar 12 and rotate it to an appropriate angle, thereby driving the connecting cross bar 10 to rotate. The connecting cross bar 10 drives the sleeve connecting rod 9 to rotate. The sleeve connecting rod 9 drives the sleeve 6 to rotate, so that the rotating sleeve 5 rotates on the surface of the base clamp 1. Then place the raw material on the fixing plate 16, and the anti-slip layer 17 plays an anti-slip effect. Then hold the operating cross bar 12 and press it downwards, thereby driving the connecting cross bar 10 and the connecting vertical rod 11 to apply force to drive the electric drill to move. At the same time, start the electric drill to perform drilling operations. During this period, different drilling directions and depth requirements can be adapted by rotating the operating cross bar 12 and adjusting the auxiliary mechanism up and down, which greatly improves the use effect.

[0027] Refer to Figures 2-3As shown, a casing connecting rod 9 is fixedly arranged on one side of the casing 6. An auxiliary mechanism is hinged on one side of the casing connecting rod 9. The auxiliary mechanism includes a connecting cross bar 10 hinged on one side of the casing connecting rod 9. Connecting vertical rods 11 are hinged between the two connecting cross bars 10. A control cross bar 12 is fixedly arranged on one side of one of the connecting cross bars 10. One side of the connecting vertical rod 11 is bolted with an angle steel 13 and a support frame 14. The support frame 14 is arranged at the bottom of the angle steel 13. Bolt holes 15 are formed on the surface of the support frame 14. If it is necessary to fix the base fixture 1 on an external support, rotate the fixing bolt 8 to drive the fixing bolt 8 to separate from the threaded hole 7, so that the rotating sleeve 5 and the casing 6 are separated from the fixing bolt 8. Then move the casing 6 up and down on the surface of the rotating sleeve 5 to effectively adjust the distance of the casing 6. After reaching the appropriate position, rotate the fixing bolt 8 into the threaded hole 7 to fix and adjust the height of the casing 6. But when the overall height needs to be adjusted, start the electric telescopic rod 4 to drive the rotating sleeve 5 to move, so as to adjust the overall height. Then hold the control cross bar 12 and rotate it to an appropriate angle to drive the connecting cross bar 10 to rotate. The connecting cross bar 10 drives the casing connecting rod 9 to rotate. The casing connecting rod 9 drives the casing 6 to rotate, so that the rotating sleeve 5 rotates on the surface of the base fixture 1. Then place the raw material on the fixing plate 16, and the anti-slip layer 17 plays an anti-slip effect.

[0028] Referring to Figures 4-5 As shown, a fixing plate 16 is fixedly arranged on one side of the base fixture 1. An anti-slip layer 17 is fixedly arranged on the upper surface of the fixing plate 16. Stabilizing blocks 18 are arranged at the bottoms of the base fixture 1 and the fixing plate 16. Two suction cups 19 are fixedly arranged at the bottoms of the stabilizing blocks 18. The threaded column 3 can be rotated to drive the threaded column 3 to rotate and move downward inside the threaded groove 2, and rotate into the threaded groove to be fixed, so as to fix the base fixture 1. At the same time, the suction cups 19 are driven to be fixed to the external support, so as to improve the stability. If it is necessary to directly place it on the ground for work, rotate the threaded column 3 until the height of the bottom end of the threaded column 3 is lower than the suction cups 19, so that the suction cups 19 are directly in contact with the ground for fixing. Then place the electric drill on the support frame 14, and insert the drill bit on one side of the electric drill downward into the bolt hole 15, and make the top of the electric drill abut against the angle steel 13, so that it is more labor-saving for the staff to hold the electric drill for work and also plays a stabilizing effect.

[0029] The working principle of the present utility model:

[0030] The utility model relates to a drill fixing device with a portable rotatable bracket for opening holes in a confined space. When the device is in use, first move the device to a suitable position. Then, if it is necessary to fix the base fixture 1 on an external bracket, the threaded column 3 can be rotated to drive the threaded column 3 to rotate and move downward inside the threaded groove 2, and rotate into the threaded groove to be fixed, so as to fix the base fixture 1. At the same time, the suction cup 19 is driven to be fixed to the external bracket, thereby improving stability. If it is necessary to directly place it on the ground for work, rotate the threaded column 3 until the height of the bottom end of the threaded column 3 is lower than the suction cup 19, so that it can be directly fixed by contacting the ground through the suction cup 19. Then, place the bottom of the drill on the support frame 14, and insert the drill bit on one side of the drill downward into the bolt hole 15, and abut the top of the drill against the angle steel 13, so that it is more labor-saving for the staff to hold the drill for work and also has a stabilizing effect;

[0031] Then rotate the fixing bolt 8 to drive the fixing bolt 8 to separate from the threaded hole 7, so that the rotating sleeve 5 and the sleeve 6 are separated from the fixing bolt 8. Then, move the sleeve 6 up and down on the surface of the rotating sleeve 5 to effectively adjust the distance of the sleeve 6. After reaching the appropriate position, rotate the fixing bolt 8 into the threaded hole 7 to fix and adjust the height of the sleeve 6. When the overall height needs to be adjusted, start the electric telescopic rod 4 to drive the rotating sleeve 5 to move, so as to adjust the overall height. Then, hold the operating cross bar 12 and rotate it to an appropriate angle, so as to drive the connecting cross bar 10 to rotate. The connecting cross bar 10 drives the sleeve connecting rod 9 to rotate, and the sleeve connecting rod 9 drives the sleeve 6 to rotate, so that the rotating sleeve 5 rotates on the surface of the base fixture 1. Then, place the raw material on the fixing plate 16, and the anti-slip layer 17 plays an anti-slip effect. Then, hold the operating cross bar 12 and press it downward, so as to drive the connecting cross bar 10 and the connecting vertical rod 11 to apply force to drive the drill to move. At the same time, the staff presses the switch of the drill to start the drill rod at the bottom of the drill to rotate for drilling operations. During this period, different drilling directions and depth requirements can be adapted by rotating the operating cross bar 12 and adjusting the auxiliary mechanism up and down, which greatly improves the use effect;

[0032] Using this device, when it rotates to the minimum pipe spacing of 150 mm, the space of the drill diameter operating cross bar can be reduced to less than 10 mm. It is not limited by height and can drill holes arbitrarily within the space of about one drill height + 250 mm. This device is simple and easy to operate, with reasonable force and convenient operation. It makes good use of the narrow space and greatly improves the use effect.

[0033] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
