Description

Technical Field

[0001] The utility model relates to the technical field of hole-turning equipment, in particular to a foldable portable hole-turning equipment. Background Art

[0002] In the process of mechanical processing, the hole turning device is a common processing device, which can be used to open holes in products. Its application is relatively frequent, but the existing hole turning equipment still has some shortcomings when used.

[0003] At present, most of the hole-turning equipment is large in size and heavy in weight. When hole-turning operations are required at different construction sites, it is inconvenient to move and carry. The construction operation is difficult, time-consuming and labor-intensive, and the work efficiency is low. Therefore, a foldable portable hole-turning equipment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a foldable portable hole-turning device that can solve the problems of the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable portable hole-turning device, comprising a flat plate, a placement groove is provided on the surface of the flat plate, two support columns are rotatably connected inside the placement groove, a motor is fixedly connected to the opposite side of the two support columns, a drill bit is installed on the output end of the motor, two cavities are provided inside the flat plate, and a folding mechanism is provided inside the two cavities.

[0006] Preferably, the folding mechanism includes a first rotating shaft, which is rotatably connected inside the cavity, one end of the first rotating shaft is fixedly connected to one side of the support column, one end of the first rotating shaft inside the cavity is fixedly connected to a ratchet, and a second rotating shaft is rotatably connected inside the cavity, one end of the second rotating shaft is fixedly connected to a pawl, and the pawl and the ratchet are meshingly connected.

[0007] Preferably, the bottom of the flat plate is rotatably connected to a universal wheel, and one side of the flat plate is fixedly connected to a handle.

[0008] Preferably, a first torsion spring is movably sleeved on the surface of the first rotating shaft, and two ends of the first torsion spring are respectively fixedly connected to the inner wall of the cavity and the first rotating shaft.

[0009] Preferably, a second torsion spring is movably sleeved on the surface of the second rotating shaft, and two ends of the second torsion spring are fixedly connected to the inner wall of the cavity and the second rotating shaft respectively.

[0010] Preferably, one end of the second rotating shaft extending to one side of the flat plate is fixedly connected with a block, the block is C-shaped, and a protrusion is fixedly connected to the side of the flat plate close to the block, the protrusion is semicircular, a groove is provided inside the block, and a moving block is slidably connected inside the groove.

[0011] Preferably, an elastic spring is slidably connected inside the groove, and two ends of the elastic spring are fixedly connected to the inner wall of the groove and the moving block respectively.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) When the support column needs to be retracted into the placement groove, the card block is first rotated. When the card block moves toward the side of the protrusion, the rotation of the card block will drive the second rotating shaft to rotate, and the second torsion spring is stretched. When the surface of the moving block contacts the semicircular surface of the protrusion, the moving block is pulled to move into the groove, and the elastic spring is compressed. When the moving block is retracted into the groove, the card block is no longer blocked and the card block can continue to rotate. When the protrusion enters the C-shaped interior of the card block, the moving block is released, and the elastic spring is reset by its own elastic characteristics to move the moving block out of the groove. At this time, the plane of the moving block and the plane of the protrusion fit each other, so that the position of the card block is fixed, and the pawl is disengaged from the ratchet. At this time, the ratchet can rotate, so that the support column can be retracted into the placement groove. One person can complete the operation, which is convenient and fast with high work efficiency.

[0014] (2) When the angle of the support column needs to be adjusted, the support column is first rotated. The rotation of the support column drives the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the ratchet to rotate. The ratchet pawl will continuously jump when the ratchet is rotated. At this time, the ratchet is not restricted by the pawl, and the angle of the support column can be increased. The rotation of the first rotating shaft drives the first torsion spring to rotate, and the rotation of the pawl drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the second torsion spring to rotate. Due to the elastic characteristics of the first torsion spring and the second torsion spring themselves, the first torsion spring and the second torsion spring will reset and respectively drive the ratchet and the pawl to rotate in relative directions. At this time, the pawl clamps the ratchet to prevent the support column from shaking, which makes the positioning of the drill bit inaccurate, reduces the construction difficulty of the operator, and thus improves the construction efficiency.

DETAILED DESCRIPTION

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a foldable portable hole-turning device, comprising a flat plate 1, a placement slot 2 is provided on the surface of the flat plate 1, two support columns 3 are rotatably connected inside the placement slot 2, a motor 4 is fixedly connected to the opposite side of the two support columns 3, a drill bit 5 is installed on the output end of the motor 4, a universal wheel 6 is rotatably connected to the bottom of the flat plate 1, a handle 7 is fixedly connected to one side of the flat plate 1, two cavities 8 are provided inside the flat plate 1, and a folding mechanism is arranged inside the two cavities 8;

[0024] When it is necessary to drill a hole in the wall, first, the two support columns 3 are opened to the same angle as the wall through the folding mechanism arranged inside the two cavities 8. Then, the operator pushes the flat plate 1 to move by the cooperation of the handle 7 and the universal wheel 6 until the drill bit 5 touches the wall. Then, the motor 4 is started. At this time, the output end of the motor 4 drives the drill bit 5 to rotate, so that a hole can be drilled in the wall. When not in use, the support column 3 and the motor 4 can be put into the placement slot 2 through the folding mechanism, which is convenient for carrying and moving the equipment and improves work efficiency.

[0025] The folding mechanism includes a first rotating shaft 9, which is rotatably connected to the inside of the cavity 8, one end of the first rotating shaft 9 is fixedly connected to one side of the support column 3, one end of the first rotating shaft 9 inside the cavity 8 is fixedly connected to a ratchet 10, a first torsion spring 11 is movably sleeved on the surface of the first rotating shaft 9, and the two ends of the first torsion spring 11 are respectively fixedly connected to the inner wall of the cavity 8 and the first rotating shaft 9, a second rotating shaft 12 is rotatably connected to the inside of the cavity 8, one end of the second rotating shaft 12 is fixedly connected to a pawl 13, the pawl 13 and the ratchet 10 are meshed and connected, a second torsion spring 14 is movably sleeved on the surface of the second rotating shaft 12, and the two ends of the second torsion spring 14 are respectively fixedly connected to the inner wall of the cavity 8 and the second rotating shaft 12;

[0026] When the angle of the support column 3 needs to be adjusted, the support column 3 is first rotated. The rotation of the support column 3 drives the first rotating shaft 9 to rotate, and the rotation of the first rotating shaft 9 drives the ratchet 10 to rotate. The ratchet 10 rotates and the pawl 13 will continue to jump. At this time, the ratchet 10 is not restricted by the pawl 13, and the angle of the support column 3 can be increased. The rotation of the first rotating shaft 9 drives the first torsion spring 11 to rotate, and the rotation of the pawl 13 drives the second rotating shaft 12 to rotate. The rotation of the second rotating shaft 12 drives the second torsion spring 14 to rotate. Due to the elastic characteristics of the first torsion spring 11 and the second torsion spring 14 themselves, the reset of the first torsion spring 11 and the second torsion spring 14 will respectively drive the ratchet 10 and the pawl 13 to rotate in relative directions. At this time, the pawl 13 jams the ratchet 10 to prevent the support column 3 from shaking, which makes the positioning of the drill bit 5 inaccurate, reduces the construction difficulty of the operator, and thus improves the construction efficiency.

[0027] The first torsion spring 11 relies on its own elastic characteristics to continuously apply reverse torque to the ratchet 10 while the first rotating shaft 9 rotates, so that the ratchet 10 can be stabilized at an angle, thereby preventing the support column 3 from continuously rotating due to the influence of gravity, thereby better controlling the opening angle of the support column 3.

[0028] A clamping block 15 is fixedly connected to one end of the second rotating shaft 12 extending to one side of the flat plate 1. The clamping block 15 is in a C shape. A protrusion 19 is fixedly connected to one side of the flat plate 1 close to the clamping block 15. The protrusion 19 is semicircular. A groove 16 is provided inside the clamping block 15. A moving block 17 is slidably connected inside the groove 16. An elastic spring 18 is slidably connected inside the groove 16. Two ends of the elastic spring 18 are fixedly connected to the inner wall of the groove 16 and the moving block 17 respectively.

[0029] When it is necessary to retract the support column 3 into the placement groove 2, the block 15 is first rotated. When the block 15 moves toward the side of the protrusion 19, the rotation of the block 15 will drive the second rotating shaft 12 to rotate, and the second torsion spring 14 is stretched. When the surface of the moving block 17 contacts the semicircular surface of the protrusion 19, the moving block 17 is pulled to move into the groove 16, and the elastic spring 18 is compressed. When the moving block 17 is retracted into the groove 16, the block 15 is no longer blocked and can continue to rotate. When the protrusion 19 enters the C-shaped interior of the card block 15, the moving block 17 is released, and the elastic spring 18 is reset by its own elastic characteristics to move the moving block 17 out of the groove 16. At this time, the plane of the moving block 17 and the plane of the protrusion 19 fit each other, so that the position of the card block 15 is fixed, and the pawl 13 is disengaged from the ratchet 10. At this time, the ratchet 10 can rotate, and the support column 3 can be retracted into the placement groove 2. One person can complete the operation, which is convenient and fast with high work efficiency.

[0030] Working principle: when it is necessary to adjust the angle of the support column 3, first rotate the support column 3. The rotation of the support column 3 drives the first rotating shaft 9 to rotate, and the rotation of the first rotating shaft 9 drives the ratchet 10 to rotate. The ratchet 10 rotates and the pawl 13 will continue to jump. At this time, the ratchet 10 is not restricted by the pawl 13, and the angle of the support column 3 can be increased. The rotation of the first rotating shaft 9 drives the first torsion spring 11 to rotate, and the rotation of the pawl 13 drives the second rotating shaft 12 to rotate. The rotation of the second rotating shaft 12 drives the second torsion spring 14 to rotate. Due to the elastic characteristics of the first torsion spring 11 and the second torsion spring 14 themselves, the reset of the first torsion spring 11 and the second torsion spring 14 will respectively drive the ratchet 10 and the pawl 13 to rotate in relative directions. At this time, the pawl 13 jams the ratchet 10 to prevent the support column 3 from shaking, which makes the positioning of the drill bit 5 inaccurate, reduces the construction difficulty of the operator, and thus improves the construction efficiency.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
