Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically, to a construction electric drill bracket with adjustable height. Background Art

[0002] An electric drill is a drilling tool powered by electricity and is also a commonly used mechanical tool in building construction. During the building construction process, an electric drill is often required to drill holes in the wall. Sometimes, when the drilling position is too high, such as drilling holes at the top of the wall, it is often necessary to use a corresponding electric drill bracket to raise the electric drill to a suitable height for the smooth progress of the drilling operation.

[0003] The Chinese patent discloses an electric drill bracket with the publication number of CN116160044A. It is proposed in the text that "a support frame, a control frame, a lifting frame and a linkage frame. Anywhere between the two ends of the support frame is connected with a control frame, the end of the control frame is connected with the lifting frame, the length from the connection point of the control frame and the lifting frame to the connection point of the support frame and the control frame is less than half of the length of the control frame, the support frame and the lifting frame are connected by a linkage frame, and the linkage frame and the control frame are parallel or extended and intersecting. In the present invention, the electric drill is installed at the installation position on the lifting frame, and at the same time, the electric drill is lifted to a suitable height by a labor-saving lever to drill holes in the building floor slab or areas where it is inconvenient for the operator to hold the electric drill for construction. Moreover, the structure is simple and convenient for the operator to carry and transport, greatly increasing the efficiency of the construction workers."

[0004] However, the overall height of the bracket in the above patent depends on the support frame and the lifting frame. If these two are relatively long, it will lead to a relatively high overall height of the bracket, a large occupied volume, and affect the portability. If they are relatively short, it will not be able to meet the drilling operations at the top of some walls with relatively high storeys, and thus its applicability is relatively low.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0027] The preferred embodiment of the construction electric drill bracket with adjustable height provided by the present invention is as Figures 1 to 5 shown: A construction electric drill bracket with adjustable height includes a main support rod 7; an auxiliary support rod 2 movably connected to the top end of the main support rod 7; a linkage rod 1 rotatably connected to the upper end of the front surface of the auxiliary support rod 2 and a control rod 4 rotatably connected to the lower end of the front surface of the auxiliary support rod 2, and the length of the control rod 4 is greater than the length of the linkage rod 1; an auxiliary jacking rod 9 arranged on one side of the auxiliary support rod 2, and the upper end and the lower end of the front surface of the auxiliary jacking rod 9 are respectively rotatably connected to one end of the linkage rod 1 and the control rod 4; a main jacking rod 10 movably connected to the top end of the auxiliary jacking rod 9; a wiring assembly 8 assembled on one side of the auxiliary jacking rod 9 and the main jacking rod 10, and the wiring assembly 8 is used for sorting and bundling the wires of the electric drill; an adjusting assembly 6 assembled between the auxiliary support rod 2 and the main support rod 7, the auxiliary jacking rod 9 and the main jacking rod 10, and the adjusting assembly 6 is respectively used for limiting and fixing the auxiliary support rod 2 and the main support rod 7, the auxiliary jacking rod 9 and the main jacking rod 10 after sliding adjustment.

[0028] The adjusting assembly 6 includes: an adjusting groove 607 opened inside the secondary support rod 2 and the secondary lifting rod 9; a reserved groove 604 opened inside the secondary support rod 2 and the secondary lifting rod 9 at one end of the adjusting groove 607; a sliding block 606 movably connected inside the reserved groove 604; a positioning rod 608 fixedly connected to one end of the sliding block 606, with one end of the positioning rod 608 extending into the adjusting groove 607; a pull rod 603 fixedly connected to the other end of the sliding block 606, with one end of the pull rod 603 extending outside the reserved groove 604; a fixing spring 605 wound around the surface of the pull rod 603, with both ends of the fixing spring 605 fixedly connected to the inner wall of the reserved groove 604 and one end of the sliding block 606 respectively; an adjusting rod 602 fixedly connected to one end of the main support rod 7 and the main lifting rod 10; and positioning holes 601 equally spaced on the front surface of the adjusting rod 602.

[0029] It should be noted that some existing construction electric drill brackets with adjustable height still have certain deficiencies in the actual use process. The overall height of the bracket depends on the support frame and the lifting frame. If these two are relatively long, the overall height of the bracket will be relatively high, occupying a large volume and affecting portability. If they are relatively short, it will not be able to meet the drilling operations on the wall tops with relatively high floor heights, thus resulting in low applicability.

[0030] In this embodiment, first, the heights between the auxiliary support rod 2 and the main support rod 7, and between the auxiliary lifting rod 9 and the main lifting rod 10 are adjusted according to the height of the wall top to be drilled. By pulling the pull rod 603, the sliding block 606 slides to drive the positioning rod 608 to slide and compress the fixing spring 605 until it completely disengages from the inside of the positioning hole 601. Then, according to the actual situation, the auxiliary support rod 2 or the main lifting rod 10 is pulled respectively. After the adjusting rod 602 slides to an appropriate distance, the pull rod 603 is released. Using the elastic force of the fixing spring 605, the sliding block 606 and the positioning rod 608 slide and snap into the appropriate positioning hole 601, realizing the limit fixation after the sliding of the adjusting rod 602. Furthermore, the height of the overall bracket can be changed to meet the drilling requirements of wall tops with different heights. And when not in use, the auxiliary support rod 2 and the main support rod 7, and the auxiliary lifting rod 9 and the main lifting rod 10 are slid to the shortest, reducing the volume of the overall bracket and facilitating carrying. Then, the electric drill is installed on the main lifting rod 10 using the reserved screw hole of the main lifting rod 10, and the wires on the electric drill are sorted out using multiple wiring components 8 to avoid the inconvenience or safety hazards caused by the random flying of the wires when the electric drill is in the air. Then, the overall bracket is erected, and the bottom end of the main support rod 7 is made to abut against the ground. At this time, the anti-slip pattern 11 is used to improve the anti-slip stability of the contact at the bottom end of the main support rod 7. Then, the locking knob 5 is loosened, and the staff presses the control rod 4 downward, so that the auxiliary lifting rod 9 rises to drive the electric drill to rise for drilling operations. And after it is contracted to the shortest in the subsequent non-use, the locking knob 5 is tightened to prevent the linkage rod 1, the auxiliary support rod 2, the control rod 4, and the auxiliary lifting rod 9 from deflecting, opening, or contracting randomly, improving the stability of the four when placed without use.

[0031] In a further preferred embodiment of the present utility model, a sliding structure is formed between the adjusting rod 602 and the inside of the adjusting groove 607, and the shapes of the top views of the adjusting rod 602 and the adjusting groove 607 are in the shape of a Chinese character 'gong'.

[0032] In this embodiment, the sliding between the 'gong'-shaped adjusting rod 602 and the adjusting groove 607 is utilized to improve the smoothness of the sliding adjustment between the two.

[0033] In a further preferred embodiment of the present utility model, a sliding structure is formed between the sliding block 606 and the inside of the reserved groove 604, and the shapes of the cross-sections of the reserved groove 604 and the sliding block 606 are in the shape of a cross.

[0034] In this embodiment, the sliding between the cross-shaped sliding block 606 and the inside of the reserved groove 604 is utilized to improve the smoothness of the sliding of the positioning rod 608. Embodiment 2

[0035] On the basis of Embodiment 1, a preferred embodiment of the construction electric drill bracket with adjustable height provided by the present utility model is as follows Figures 1 to 5As shown in the figure: The wiring component 8 includes: a fixed seat 806 fixedly connected to one side of the secondary jacking rod 9 and the main jacking rod 10; a sliding rod 803 fixedly connected to the inner wall of the fixed seat 806; a slider 805 slidably connected to the surface of the sliding rod 803; a return spring 804 wound around the surface of the sliding rod 803, with both ends of the return spring 804 fixedly connected to one end of the slider 805 and the inner wall of the fixed seat 806 respectively; a wiring frame 801 fixedly connected to one side of the slider 805; and a fixed rod 802 fixedly connected to the front of the wiring frame 801.

[0036] In this embodiment, by sequentially pulling the fixed rod 802 to drive the wiring frame 801 to slide, the slider 805 slides on the surface of the sliding rod 803 to compress the return spring 804 to a suitable position, then the electric drill wire is clamped to one side of the fixed seat 806, and then the fixed rod 802 is released. Using the elastic force of the return spring 804, the slider 805 slides to drive the wiring frame 801 to return to its original position. Furthermore, the movement range of the wire is limited by the wiring frame 801, making the wires more neatly distributed on the secondary jacking rod 9 and the main jacking rod 10, avoiding the inconvenience caused by the random flying of the wires when the electric drill is at a high altitude, or the potential safety hazards caused by the inadvertent touching and pulling of the wires by the staff when walking.

[0037] In a further preferred embodiment of the present utility model, the shape of the top view of the wiring frame 801 is U-shaped, and the wiring frame 801 forms a sliding structure with the surface of the sliding rod 803 through the slider 805.

[0038] In this embodiment, the U-shaped wiring frame 801 is used to facilitate the limitation of the movement range of the wire.

[0039] In a further preferred embodiment of the present utility model, a rubber sleeve 3 is sleeved on one end of the surface of the control rod 4, and the surface of the rubber sleeve 3 is rounded.

[0040] In this embodiment, the rubber sleeve 3 is used to improve the comfort of the staff when pressing the control rod 4.

[0041] In a further preferred embodiment of the present utility model, a locking knob 5 is rotatably connected to one side of the front surface of the control rod 4. The locking knob 5 is used to threadedly lock or release the rotation between the secondary support rod 2 and the control rod 4, avoiding the random deflection opening or contraction of the linkage rod 1, the secondary support rod 2, the control rod 4, and the secondary jacking rod 9, and improving the stability of the four when not in use and placed.

[0042] In a further preferred embodiment of the present utility model, anti-slip patterns 11 are equidistantly arranged at the bottom end of the main support rod 7, and the cross-sectional shape of the anti-slip patterns 11 is arc-shaped.

[0043] In this embodiment, the arc-shaped anti-slip patterns 11 are used to improve the anti-slip stability of the bottom end of the main support rod 7 when placed on the ground.

[0044] In summary, the adjusting component 6 is used to realize the limit fixation after the sliding between the secondary support rod 2 and the main support rod 7, and between the secondary jacking rod 9 and the main jacking rod 10, which is convenient for changing its overall length, avoiding the limitations that the traditional support frame and the jacking frame are relatively long, resulting in a relatively high overall height of the bracket, large occupied volume and affecting carrying, while if they are relatively short, they cannot meet the requirements for wall top drilling operations with relatively high floor heights. The secondary jacking rod 9 can be used to sort and distribute the electric drill wires, avoiding the inconvenience caused by the random flying of the wires when the electric drill is at high altitude, or the potential safety hazards caused by the inadvertent touching and pulling of the wires by the staff when walking.

[0045] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
