Description

Technical Field

[0001] This utility model belongs to the field of mobile device technology and relates to a power tool mobile frame. Background Technology

[0002] Power tools like cutting machines are handheld, requiring workers to hold them and move them along the cutting path. This method is only suitable for short-distance cuts. For long-distance cuts, the heavy tools can cause fatigue from prolonged handling, and cutting accuracy is difficult to guarantee. Furthermore, for long-distance vertical cuts, workers need to use ladders or other tools to climb and hold the tools, resulting in low efficiency and difficulty in ensuring cutting accuracy. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems existing in the use of existing power tools by proposing a mobile frame capable of driving the power tool to lift, move, and translate.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A power tool mobile frame, characterized in that it includes a base and a support rod assembly disposed on the base, the support rod assembly is provided with a mounting part for mounting power tools, and a driving mechanism is further provided between the support rod assembly and the mounting part for driving the mounting part to vertically rise and fall along the support rod assembly.

[0006] The base is equipped with wheels at the bottom and a support part at the top of the strut assembly. The height of the strut assembly is adjustable to accommodate buildings of different heights. The strut assembly is movably mounted on the base, which is equipped with an adjustment component. This adjustment component is used to drive the strut assembly to rise and fall so that the support part presses against the ceiling of the building.

[0007] In the aforementioned power tool moving frame, the driving mechanism includes a rack fixed on the support rod assembly and a gear rotatably mounted on the mounting part. The gear meshes with the rack, and rotating the gear drives the entire mounting part to rise and fall.

[0008] In the aforementioned power tool moving frame, the mounting part includes a mounting base, a mounting component one and a mounting component two disposed on the mounting base. The mounting component one is rotatably disposed on the mounting base via a rotating shaft one, and the mounting component two is rotatably disposed on the mounting component one via a rotating shaft two. The rotating shaft one and the rotating shaft two are horizontally disposed and perpendicular to each other. The mounting component one is fixedly connected to the mounting base via a fastener one, and the mounting component two is fixedly connected to the mounting component one via a fastener two.

[0009] In the aforementioned power tool moving frame, the gear is rotatably mounted on the mounting base, and a handle is also rotatably mounted on the mounting base, the handle being fixedly connected to the gear.

[0010] In the aforementioned power tool moving frame, the second mounting component is provided with several corner pieces for fixing the power tools.

[0011] In the aforementioned power tool moving frame, the support rod assembly includes an outer tube and an inner tube. Several outer tubes are spliced ​​together along the length direction, and adjacent two outer tubes are fixedly connected by an inner tube. The outer tubes are sleeved outside the inner tube.

[0012] In the aforementioned power tool moving frame, a rack of the same length as the outer tube is fixed to the outer wall of each outer tube.

[0013] In the aforementioned power tool moving frame, a guide tube is fixed on the base, and an outer tube is sleeved outside the guide tube and can move up and down along the guide tube.

[0014] In the aforementioned power tool moving frame, the adjusting assembly includes a base plate, a support, and a foot lever. The base plate is fixed on the base, and the support rod assembly is mounted on the base plate. A roller is provided on both sides of the support. The support is rotatably mounted on the support rod assembly via a first pin, and the foot lever is rotatably mounted on the support via a second pin. The first and second pins are respectively located on both sides of the roller. A hook is provided on the foot lever, and the end of the hook is hooked onto the base plate. When the foot lever is stepped on, the entire support swings around the roller and drives the support rod assembly to rise.

[0015] In the aforementioned power tool moving frame, a tension spring is also provided between the bracket and the foot lever. The two ends of the tension spring are hooked onto the bracket and the foot lever respectively, for pulling the foot lever so that the hook on the foot lever is always hooked onto the base plate.

[0016] In the aforementioned power tool moving frame, the abutment part includes a screw, a nut, an upper bushing, and a lower bushing. The upper and lower bushings are spaced apart vertically and inserted into the inner cavity of the outer tube at the top of the support rod assembly. A baffle is fixedly provided on the top of the upper bushing, and the baffle abuts against the outer end face of the outer tube. The nut is located between the upper and lower bushings and can only move up and down relative to the outer tube. A spring is provided between the nut and the lower bushing. The screw passes through the upper bushing, nut, spring, and lower bushing in sequence and can move up and down relative to the upper and lower bushings. Rotating the screw causes it to move up and down relative to the outer tube.

[0017] In the aforementioned power tool moving frame, the outer periphery of the nut is provided with an anti-rotation surface, which fits against the inner wall of the outer tube to restrict the rotation of the nut.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. For buildings of different heights, select the corresponding number and length of outer tubes for assembly to make the height compatible. The top of the assembled strut assembly is elastically pressed against the ceiling of the building by the screw rod. Install the power tool on the second mounting part and drive the power tool to rise and fall by turning the handle. No need for workers to hold it, reducing labor intensity and improving cutting accuracy and efficiency.

[0020] 2. If the height of the strut assembly deviates from the height of the building and cannot be adjusted by replacing the existing outer tube, stepping on the pedal will cause the entire support to swing around the roller, raising the strut assembly and pressing the lead screw against the ceiling of the building, thus achieving fine adjustment.

[0021] 3. The power tool can rotate around two horizontal and perpendicular pivots, namely pivot one and pivot two, thereby adjusting the angle of the power tool. Attached Figure Description
