Description

Technical Field

[0001] The utility model relates to the technical field of wall drilling, in particular to a wall dust-proof drilling machine. Background Art

[0002] A drill rig is a device that uses electricity as power to drill holes in a work surface. It is a relatively common product among power tools and is widely used in the field of construction. Drills are used frequently, both during the construction process and in the decoration process after construction is completed. In particular, during interior decoration, drills are used to drill holes in the wall when installing essential household appliances such as lamps, curtains, and air conditioners. However, during the drilling process, debris and dust will fly everywhere as the drill bit penetrates the wall, seriously polluting the indoor environment. Especially after the furniture is delivered, when drilling vertical holes in the ceiling, dust will float everywhere and fall on the furniture, which is difficult to clean. In addition, the drill rig is usually handheld by the worker, and the head is close to the drill bit. Dust and debris can enter the worker's nose and eyes, posing a certain threat to the worker. Some workers put plastic bags in the middle of the drill to catch the debris, but the dust still floats into the air, making the effect less effective. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a wall dustproof drilling rig.

[0004] The technical solution of this utility model is as follows:

[0005] A wall dustproof drilling machine comprises a drilling machine body, wherein an output drill bit is fixed to an output drill bit at an output end of the drilling machine body through a drill bit fixing sleeve.

[0006] The drill bit fixing sleeve is detachably mounted with an annular clamping sleeve on the outer edge surface close to the drill bit body. The outer edge surface of the annular clamping sleeve is provided with multiple sleeves, and the axis thereof is parallel to the extension direction of the output drill bit.

[0007] Connecting rods are provided through each of the multiple sleeves, the top ends of the connecting rods are connected to a dust collection box, and the output drill bit is provided through the dust collection box;

[0008] The upper end of the dust collecting box is open and connected with a corrugated hose, and the corrugated hose can extend to a farthest position away from the dust collecting box and exceed the end of the output drill bit.

[0009] In order to enable the sleeve to limit the connecting rod when the drilling rig is used vertically to prevent it from falling due to its own weight, the connecting rod and the sleeve are connected by an interference fit.

[0010] The specific design of the annular ferrule is that the annular ferrule is set to an open shape, and docking blocks are set at both ends of the opening position, and the annular ferrule is locked by passing the docking blocks through the locking bolts.

[0011] In order to strengthen the connection strength between the dust box and the annular ferrule, a limiting cylinder is installed on the outer edge surface of the dust box, and a limiting hole is opened on any docking block, and the axes of the limiting cylinder and the limiting hole are parallel to the extension direction of the output end head. A limiting rod is set through the limiting cylinder and the limiting hole, and the limiting rod is connected to the two by interference fit.

[0012] In order to limit the dust box after it moves to a certain distance, the axis of the limiting cylinder and the limiting hole are staggered, and the limiting rod is a bent rod with the bent end located between the limiting cylinder and the docking block.

[0013] In order to facilitate the installation of the connecting rod on the dust box, a fixing block is provided at the bottom of the dust box, and the number and position of the fixing block are consistent with the sleeve. The fixing block is provided with a socket for inserting the connecting rod at one end facing the annular sleeve.

[0014] In order to improve the stability of the dust box, three connecting rods are provided and are evenly distributed around the bottom of the dust box.

[0015] In order to facilitate the discharge of debris and dust collected by the dust box and the corrugated hose, a dust discharge port is opened at the bottom of the dust box, and the dust discharge port is connected to a dust discharge pipe through a joint.

[0016] In order to be able to unload the collected debris and dust to a location far away from the staff and facilitate the movement of the drilling rig, the length of the dust unloading pipe is greater than the length of the drilling rig body and is made of a corrugated pipe.

[0017] The beneficial effects of the present invention are as follows: the present invention is a wall dust-proof drilling rig. First, the output drill bit can be fixed by cooperating with the drill bit fixing sleeve through the drilling rig main body, and can drive the output drill bit to rotate to complete basic drilling operations; secondly, the dust collection box is connected by the annular sleeve and the connecting rod, and a corrugated hose is installed above the dust collection box, so that the output drill bit can be covered when the output drill bit is drilling, which can prevent dust and debris from flying away, and can collect the generated debris and dust, effectively protecting the environment of the construction site and the health of the workers, and the connecting rod and the limit rod connected by interference fit can enable the dust collection box to still slide along the connecting rod and the limit rod when the corrugated hose is compressed to the limit position, which is convenient for collecting debris and dust when drilling deeper holes; finally, by arranging a dust discharge port and a dust discharge pipe at the bottom of the dust collection box, the collected debris and dust can be discharged in time, avoiding accumulation in the corrugated hose, reducing the number of shutdowns to clean dust and debris, and improving the efficiency of drilling.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, when carrying out interior decoration, a drilling rig is needed to drill more holes. A lot of dust and debris will be generated during the drilling process. On the one hand, it will pollute the indoor environment and is very difficult to clean. On the other hand, it will affect the health of the staff. When drilling, the existing staff will use a plastic bag to cover the bottom of the drill bit. Although it can absorb a certain amount of debris and dust, some of it will still float into the air. Or some directly use a corrugated hose 8 to cover the outside of the drill bit. On the one hand, the corrugated hose 8 has a certain length after compression, which affects the drilling depth of the drill bit. On the other hand, the collected debris and dust need to be frequently poured out, affecting the efficiency of drilling. The following is a detailed explanation with reference to the diagram.

[0028] This embodiment provides a wall dust-proof drill. The inventor has improved the existing drill and designed a new dust-proof drill that can effectively reduce the dispersion of dust and debris. Figure 1, including a drill body 1, the output end of the drill body 1 is fixed with an output drill bit 3 through a drill bit fixing sleeve 2. This solution mainly designs a new type of drill dust collection device, which does not affect the normal drilling work of the drill. The drill body including the output drill bit 3 driving device and the handle and other components all adopt existing technologies, and the connection between the drill bit fixing sleeve 2 and the drill body 1 and the output drill bit 3 adopts the existing method, which will not be described in detail.

[0029] In this embodiment, the drill bit fixing sleeve 2 is detachably mounted with an annular sleeve 4 near the outer edge of the drill bit body. Figure 2 The annular clamp 4 is in a form similar to a clamp. The annular clamp 4 is set to an open shape, and docking blocks 9 are set at both ends of the opening position. The annular clamp 4 is locked by passing the docking blocks 9 through the locking bolts 10. The locking bolts 10 pass through the two docking blocks 9 and are fixed by nuts, and then the annular clamp 4 and the drill fixing sleeve 2 are locked and fixed.

[0030] On the basis of the above structure, a plurality of sleeves 5 are provided on the outer edge surface of the annular sleeve 4, and the axis is parallel to the extension direction of the output drill bit 3, and a connecting rod 6 is provided through the multiple sleeves 5, and the top of the connecting rod 6 is connected to the dust box 7, and the dust box 7 is in the shape of a shell with an upper end opening. In this embodiment, in order to make the dust box 7 more balanced and stable, three sleeves 5 and three connecting rods 6 are provided respectively, and the sleeves 5 are evenly arranged circumferentially on the outer edge surface of the annular sleeve 4, and the connecting rod 6 and the sleeve 5 are connected by an interference fit, that is, when there is no external force, the dust box 7 and the connecting rod 6 are in a relatively static state with the sleeve 5, which is convenient for the drill rig to drill holes in the vertical direction such as the ceiling, and the dust box 7 will not slide along the connecting rod 6 due to its own weight, and the output drill bit 3 is set through the dust box 7.

[0031] In addition, a fixing block 13 is provided at the bottom of the dust collecting box 7. Figure 3 , and the number and position of the fixing block 13 are consistent with those of the sleeve 5. The fixing block 13 is provided with a socket 14 for inserting the connecting rod 6 at one end facing the annular sleeve 4. Accordingly, three fixing blocks 13 are provided corresponding to the connecting rod 6, and the axis of the socket 14 is collinear with the axis of the sleeve 5. When installing the dust box 7, the connecting rod 6 is passed through the sleeve 5, and the upper end is inserted into the socket 14 of the fixing block 13.

[0032] Moreover, in order to cover the output drill bit 3 and reduce the dispersion of dust and debris, the upper end of the dust collecting box 7 is open and connected to a corrugated hose 8. The corrugated hose 8 is sleeved on the outer edge surface of the upper end of the dust collecting box 7, and the sleeve position has a certain elasticity and can fit tightly with the dust collecting box 7. The corrugated hose 8 can extend to the farthest position away from the dust collecting box 7 and exceed the end of the output drill bit 3, ensuring that the corrugated hose 8 can wrap it at the moment the output drill bit 3 punches a hole, thereby facilitating the collection of dust and debris.

[0033] On the basis of the above structure, a dust discharge port 15 is provided at the bottom of the dust collecting box 7, and a dust discharge pipe 16 is connected to the dust discharge port 15 through a joint. By setting the dust discharge port 15, the dust and debris collected in the dust collecting box 7 and the corrugated hose 8 can be discharged through the dust discharge pipe 16 as soon as possible, and the end of the dust discharge pipe 16 can be connected to the collection box to facilitate dust collection. Moreover, the length of the dust discharge pipe 16 is greater than the length of the drilling rig body 1, and the bellows material is used, so that the dust outlet end of the dust discharge pipe 16 is away from the staff using the drilling rig. Moreover, the bellows material can be used to extend or contract when the staff moves the handheld drilling rig, accompanying its movement.

[0034] Moreover, a limiting cylinder 11 is installed on the outer edge surface of the dust collecting box 7, and a limiting hole 12 is provided on any one of the docking blocks 9, and the axes of the limiting cylinder 11 and the limiting hole 12 are parallel to the extension direction of the output end head, and a limiting rod is provided through the limiting cylinder 11 and the limiting hole 12, and the limiting rod is connected with the two by interference fit. It should be noted that, in this embodiment, the axes of the limiting cylinder 11 and the limiting hole 12 are staggered, so that the limiting cylinder 11 and the limiting hole 12 are staggered along the axis direction of the two, and the limiting rod is set It is a bending rod, and the bending end is located between the limit cylinder 11 and the docking block 9. When the output drill bit 3 drills a deeper hole, the corrugated hose 8 is compressed to the limit position. At this time, the reaction force of the wall pushes the dust box 7 to slide along the connecting rod 6 and the limit rod. When the dust box 7 moves to the bent end of the limit rod, it stops moving. At this time, the entire limit rod moves along the limit hole 12. When the bent end moves to the limit hole 12, a limit is generated between the two, and the whole stops moving, that is, the maximum depth of the output drill bit 3 is reached, and the drilling work is stopped.
