Description

Technical Field

[0001] This utility model relates to the field of grooving device technology, and in particular to a grooving device for building electromechanical installation. Background Technology

[0002] After the existing building walls are completed, electrical wiring needs to be laid. Various electrical wirings need to be installed by slotting grooves in the walls and laying pipes. Various electrical wirings need to pass through the pipes. Slotting equipment is needed to perform the work of slotting the walls.

[0003] By comparing a grooving device for electrical conduit installation in building electromechanical installation with patent publication number CN222472665U, it is found that in this solution, pressing a button causes an electric push rod to press down the bracket, which in turn presses down the blade inside the bracket. The user can adjust the grooving depth as needed, making it more convenient for workers to use. However, when workers are using the handheld grooving device, the device itself is quite heavy, and after working for a long time, workers may experience fatigue. During the handheld grooving process, the worker's arm may shake, which may lead to deviations in the grooving path and changes in the grooving depth. In severe cases, the device may fall and cause a safety accident, resulting in injury to the worker. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, a grooving device for building electromechanical installation includes a handle 100, a grooving mechanism for grooving a wall surface, the grooving mechanism being located on the front side of the handle 100, and a support mechanism for supporting and stabilizing the device when grooving the wall surface, the support mechanism being located on the rear side of the handle 100.

[0028] In this embodiment: the grooving mechanism includes a protective cover 301 disposed on the front side of the handle 100. The protective cover 301 is connected to the handle 100 by bolts. A telescopic cover 302 is slidably installed on the upper part of the inner side of the protective cover 301. A rotating shaft 306 is rotatably installed at the center of the protective cover 301. A rotary motor 305 is installed on the rotating end of the rotating shaft 306. The output end of the rotary motor 305 is fixed to the rotating end of the rotating shaft 306 through a coupling. A fixing cover 304 is provided on the outside of the rotary motor 305. Multiple saw blades 303 are installed on the rotating shaft 306. The saw blades 303 are detachable. The handle 100 is made of rubber.

[0029] In this embodiment: the support mechanism includes two inserts 202 rotatably disposed on the rear side of the grip 100. The two inserts 202 are symmetrically arranged in the front-back direction. A rotating frame 201 is fixed to the end of the insert 202 away from the grip 100. An upper C-shaped frame 205 is slidably installed at the lower end of the rotating frame 201, with the opening of the upper C-shaped frame 205 facing upward. A lower C-shaped frame 206 is slidably installed at the lower end of the upper C-shaped frame 205, with the opening of the lower C-shaped frame 206 facing downward. A locking bolt is installed between the upper C-shaped frame 205 and the rotating frame 201. A support pad 210 is fixed at the bottom end of the lower C-shaped frame 206. The support pad 210 is made of silicone. A limiting structure is provided between the upper C-shaped frame 205 and the lower C-shaped frame 206 for unidirectionally limiting the movement direction of the support pad 210. An adjustment structure is provided between the rotating frame 201 and the grip 100 for adjusting the rotation angle of the rotating frame 201.

[0030] The limiting structure includes two sliding frames 207 slidably disposed on the side wall of the upper C-shaped frame 205. The two sliding frames 207 are located on both sides of the lower C-shaped frame 206 symmetrically in the front-back direction. One-way racks 209 are provided on the side wall of the lower C-shaped frame 206 near the sliding frames 207. A compression spring is connected between the lower C-shaped frame 206 and the upper C-shaped frame 205. Multiple one-way teeth 208 are fixed at one end of the sliding frame 207 near the one-way rack 209. The one-way rack 209 and the one-way teeth 208 slide in cooperation. A limiting spring is connected between the sliding frame 207 and the upper C-shaped frame 205. A preset gap is left between the upper end of the support pad 210 and the lower end of the upper C-shaped frame 205.

[0031] The adjustment structure includes multiple limiting holes 203 on the side wall of the grip 100. The multiple limiting holes 203 are distributed around the center of the insertion post 202. Two limiting posts 204 are slidably installed on the top of the rotating frame 201. The limiting posts 204 are threadedly connected to the limiting holes 203.

[0032] The support pad 210 has symmetrical storage slots 211 on both sides along the front-back direction. A storage plate 212 is slidably installed at the bottom of the storage slot 211. Multiple ball bearings 213 are installed at the bottom of the storage plate 212. An arc-shaped plate 216 is fixed at the top of the storage plate 212. A push plate 215 is provided on the side of the arc-shaped plate 216 away from the handle 100. A pressing plate 214 is fixed at the end of the push plate 215 near the arc-shaped plate 216. The push plate 215 is plugged into and plugged into the support pad 210. The end of the pressing plate 214 near the arc-shaped plate 216 is arc-shaped. When the pressing plate 214 presses against the arc-shaped plate 216, causing the arc-shaped plate 216 to move downward, the pressing plate 214... 4. The upper end will fit against the upper wall of the storage groove 211, and the lower end of the extrusion plate 214 will fit against the upper end of the arc plate 216. The support pad 210 in the support mechanism will abut against the wall to further support the device, thereby increasing the contact area between the device and the wall, improving the stability of the device when the operator holds it, reducing the fatigue caused by the operator holding the device, and reducing the shaking phenomenon of the device when grooving. Furthermore, the limiting structure can effectively ensure that the device will not move outwards from the wall when grooving, ensuring the uniform depth of the wall cut, and improving the quality and efficiency of grooving.

[0033] Working principle: First, rotate the rotating frames 201 on both sides to rotate the support pad 210 to a suitable angle. Then, rotate the limiting posts 204 on the rotating frames 201 on both sides into the limiting holes 203 to fix the angle of the rotating frames 201 at this time. Then, pull down the upper C-shaped frame 205 to move the support pad 210 downward and adjust the distance of the support pad 210. After adjustment, use the locking bolts to fix the position of the upper C-shaped frame 205. Then, hold the handle 100 to press the support pad 210 against the wall first to further support the device, thereby increasing the contact area between the device and the wall, improving the stability of the device when the operator holds it, reducing the fatigue of the operator when holding the device, and reducing the shaking phenomenon when the device is slotted.

[0034] The rotary motor 305 is turned on, driving the rotary shaft 306 to rotate, which in turn drives multiple saw blades 303 to rotate. Then, the operator holds the handle 100 and presses it into the wall, causing the saw blades 303 to first create a groove in the wall. When the operator holds the handle 100 and presses it into the wall, the support pad 210 will be subjected to pressure and will move in the direction of the handle 100. This will cause the lower C-shaped frame 206 to move in the direction of the handle 100. By utilizing the sliding cooperation of multiple one-way teeth 208 and one-way racks 209, the lower C-shaped frame 206 can move in one direction, which in turn will move the support pad 210 in one direction. This effectively ensures that the device will not move outwards when grooving. The depth of grooving can be precisely controlled by pressing the device to move it inwards to the required depth.

[0035] Once the device has cut the wall to the appropriate depth, the two push plates 215 can be pushed into the storage groove 211, causing the two extrusion plates 214 to press against the arc plate 216. After the arc plate 216 moves downward, the upper end of the extrusion plate 214 will be in contact with the upper wall of the storage groove 211, and the lower end of the extrusion plate 214 will be in contact with the upper end of the arc plate 216. This causes the arc plate 216 to move the storage plate 212 downward, making multiple balls 213 contact the wall. Then, the moving device moves on the wall to continue grooving the wall, reducing the friction when the device moves on the wall, making the movement smoother, and improving the quality and efficiency of grooving.

[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.
