Description

Technical Field

[0001] This utility model relates to the field of wall construction technology, specifically a wall-drilling device used in wall construction. Background Technology

[0002] A wall chisel is a tool or device used for chiseling, drilling or chiseling in a wall. In the prior art, a hammer drill-pick tri-type impact drill can be used for wall chiseling.

[0003] However, existing devices have certain drawbacks. For example, CN219820221U describes a wall-point chiseling device, which relates to the field of wall chiseling technology. This device aims to solve the problem that most existing methods rely on worker experience to control the chiseling depth, leading to inconsistent chiseling depths. The device includes a wall-pointing component, a chiseling component, a depth control component, and a positioning component. The chiseling component is mounted on the wall-pointing component. The depth control component is also mounted on the wall-pointing component.

[0004] Although the device limits the depth, in actual use, as the drill bit rotates, some small debris will be splashed outward due to centrifugal force, affecting the user's experience. In addition, the grip part of the device is fixed and cannot be adjusted, resulting in insufficient flexibility. This further prevents users with different dominant hands from gripping the device according to their own preferences. Utility Model Content

[0005] The purpose of this invention is to provide a wall-drilling device for wall construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wall-drilling device for wall construction includes a three-in-one head, wherein a drill rod is embedded and connected to the front surface of the three-in-one head, and a power cord is fixedly connected to the lower surface of the three-in-one head.

[0008] The outer surface of the three-in-one head is provided with a mounting base. An insertion plate is fixedly connected to the lower surface of the mounting base. An insertion post is fixedly connected to the upper surface of the insertion plate. A fixing module is nested and connected to the outer surface of the insertion post. The fixing module includes a mounting ring and a stud. The mounting ring is nested and movably connected to the outer surface of the insertion post. The stud is threadedly connected to the lower surface of the mounting ring. A handle is fixedly connected to the lower end of the stud.

[0009] The upper surface of the mounting base is fixedly connected to a limiting seat, and the upper surface of the limiting seat is movably connected to a depth limiting module. The depth limiting module includes a mounting sleeve and a sliding sleeve. The mounting sleeve is fixedly connected to the upper surface of the limiting seat, and a scale is movably connected to the inside of the mounting sleeve. The sliding sleeve is slidably connected to the outer surface of the scale.

[0010] The lower surface of the scale is fixedly connected to a lower connecting seat, and the lower surface of the lower connecting seat is fixedly connected to a dustproof module. The dustproof module includes a dustproof sleeve and a collection cylinder. The dustproof sleeve is fixedly connected to the front surface of the lower connecting seat, and the collection cylinder is threadedly connected to the outer surface of the dustproof sleeve.

[0011] Furthermore, the front surface of the mounting ring is provided with a slot, the insertion plate is inserted into the inside of the slot, the stud is in contact with the lower surface of the insertion plate, and the insertion post penetrates the mounting ring and contacts the three-in-one head.

[0012] Furthermore, the front surface of the limiting seat is threadedly connected to a limiting rod, the outer surface of the limiting rod is nested with a spring, and the front surface of the lower connecting seat is provided with a through hole, through which the limiting rod passes.

[0013] Furthermore, the depth limiting module also includes a first limiting knob and a second limiting knob. The first limiting knob is threadedly connected to one end of the upper surface of the scale, and the second limiting knob is threadedly connected to the upper surface of the sliding sleeve.

[0014] Preferably, the dustproof module further includes a second filter and a fan. The second filter is movably connected to the inside of the collection cylinder. A first filter is placed on the upper surface of the second filter. The fan is movably connected to the inside of the collection cylinder.

[0016] Preferably, an air outlet is provided on the outer surface of the collection cylinder and at the corresponding position of the fan.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. After loosening the handle, the mounting ring can be manually flipped to change the angle between the handle and the three-in-one head, making the device suitable for people with different hand habits and improving its practicality.

[0019] 2. Adjust the position of the sliding sleeve along the scale and rotate the second limit knob to limit the sliding sleeve. After the scale moves under force, the sliding sleeve and the mounting sleeve come into contact, preventing the drill rod from drilling forward. This completes the drilling to the specified depth. When blocking splashing wall debris, the dust cover comes into contact with the wall surface and uses its own cover structure to block the debris. Large debris can be poured out directly later, while small debris is blocked inside the collection cylinder. This device achieves drilling depth limit and prevents debris from splashing while ensuring its own flexibility of use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 In this embodiment of the utility model, a wall chiseling device for wall construction includes a three-in-one head 1, a drill rod 2 is embedded and connected to the front surface of the three-in-one head 1, and a power cord 101 is fixedly connected to the lower surface of the three-in-one head 1.

[0027] The outer surface of the three-in-one head 1 is provided with a mounting base 402. The lower surface of the mounting base 402 is fixedly connected to an insertion plate 4. The upper surface of the insertion plate 4 is fixedly connected to an insertion post 401. The outer surface of the insertion post 401 is nested with a fixing module 3. The fixing module 3 includes a mounting ring 302 and a stud 303. The mounting ring 302 is nested and movably connected to the outer surface of the insertion post 401. The stud 303 is threadedly connected to the lower surface of the mounting ring 302. The lower end of the stud 303 is fixedly connected to a handle 301.

[0028] The upper surface of the mounting base 402 is fixedly connected to the limiting base 403, and the upper surface of the limiting base 403 is movably connected to the depth limiting module 5. The depth limiting module 5 includes a mounting sleeve 501 and a sliding sleeve 504. The mounting sleeve 501 is fixedly connected to the upper surface of the limiting base 403, and a scale 503 is movably connected to the inside of the mounting sleeve 501. The sliding sleeve 504 is slidably connected to the outer surface of the scale 503.

[0029] The lower surface of the scale 503 is fixedly connected to the lower connecting seat 6, and the lower surface of the lower connecting seat 6 is fixedly connected to the dustproof module 7. The dustproof module 7 includes a dustproof sleeve 701 and a collection cylinder 702. The dustproof sleeve 701 is fixedly connected to the front surface of the lower connecting seat 6, and the collection cylinder 702 is threadedly connected to the outer surface of the dustproof sleeve 701.

[0030] Specifically, the three-in-one head 1 is a common hammer, drill, and pick three-in-one impact drill on the market, which can be used with different models of drill rods 2 for wall drilling operations. The power cord 101 is used to connect to an external power source.

[0031] The mounting base 402 is located on the outside of the three-in-one head 1. The mounting ring 302 and the three-in-one head 1 are nested together. By rotating the stud 303 through the handle 301, the stud 303 applies an upward force to the insertion plate 4, causing the insertion plate 4 to drive the insertion post 401 to rise, so that the insertion post 401 contacts the three-in-one head 1, thus completing the fixing of the mounting ring 302 and the three-in-one head 1. With the above fixing method, after loosening the handle 301, the mounting ring 302 can be manually flipped to change the angle between the handle 301 and the three-in-one head 1, making the device suitable for people with different dominant hands.

[0032] When setting the depth limit, adjust the position of the sliding sleeve 504 along the scale 503 and rotate the second limit knob 505 to limit the sliding sleeve 504. After the scale 503 moves under force, the sliding sleeve 504 contacts the mounting sleeve 501, preventing the drill rod 2 from continuing to drill forward, thus completing the drilling to the specified depth.

[0033] When blocking flying debris from the wall, the dust cover 701 contacts the wall surface and uses its own cover structure to block the debris. Large debris can be poured out directly later, while small debris is blocked inside the collection cylinder 702. This device ensures its own flexibility of use while limiting the drilling depth and preventing debris from flying. Example 1

[0034] like Figure 1-4 As shown, the front surface of the mounting ring 302 has a slot 304, the insertion plate 4 is inserted into the inside of the slot 304, the stud 303 is in contact with the lower surface of the insertion plate 4, and the insertion post 401 passes through the mounting ring 302 and contacts the three-in-one head 1.

[0035] In this embodiment, the insertion post 401 and the three-in-one head 1 contact the mounting ring 302 to limit its movement, while the handle 301 is available for the user to hold, and the angle of the handle 301 can be adjusted according to the user's dominant hand. Example 2

[0036] Based on Example 1, in order to remedy the problem that debris was not collected in Example 1.

[0037] like Figure 1-4 As shown, the front surface of the limiting seat 403 is threadedly connected to the limiting rod 404, and the outer surface of the limiting rod 404 is nested with a spring 405. The front surface of the lower connecting seat 6 is provided with a through hole 601, through which the limiting rod 404 passes. The depth limiting module 5 also includes a first limiting knob 502 and a second limiting knob 505. The first limiting knob 502 is threadedly connected to the upper surface of the scale 503 near one end, and the second limiting knob 505 is threadedly connected to the upper surface of the sliding sleeve 504.

[0038] In this embodiment, the first limit knob 502 limits the ruler 503. When limiting the depth, after adjusting the position of the sliding sleeve 504, the dustproof module 7 contacts the wall. As drilling progresses, the dustproof sleeve 701, in conjunction with the lower connecting seat 6, applies force to the ruler 503. At this time, the ruler 503 moves along the mounting sleeve 501, and the limit rod 404 moves synchronously. The limit seat 403, in conjunction with the lower connecting seat 6, compresses the spring 405. After drilling is completed, the external force is lost, and the ruler 503 and the dustproof module 7 are reset under the elastic force of the spring 405.

[0039] like Figure 1-4As shown, the dustproof module 7 also includes a second filter 704 and a fan 705. The second filter 704 is movably connected to the inside of the collection cylinder 702. A first filter 703 is placed on the upper surface of the second filter 704. The fan 705 is movably connected to the inside of the collection cylinder 702. A controller 706 is fixedly connected to the lower surface of the fan 705. A switch is movably connected to the outer surface of the controller 706. An energy storage power supply 707 is installed inside the collection cylinder 702. The energy storage power supply 707 is electrically connected to the controller 706. A threaded seat 708 is threaded to the lower end of the collection cylinder 702. An air outlet is opened on the outer surface of the collection cylinder 702 at the corresponding position of the fan 705.

[0040] In this embodiment, when collecting splashed debris, large debris is blocked by filter screen 703 and filter screen 704, and can be discharged from the dust cover 701 by shaking the device downwards. For the smaller debris that splashes out, the collecting cylinder 702 and the dust cover 701 are threaded together. The collecting cylinder 702 can be manually rotated to separate it from the dust cover 701, and then the collecting cylinder 702 can be removed. The collecting cylinder 702 has an integrally molded limiting protrusion inside. Filter screen 704 overlaps the upper surface of the limiting protrusion, and filter screen 703 overlaps the upper surface of filter screen 704. The upper end of 703 contacts the dust cover 701. Therefore, small debris is blocked by the second filter screen 704, and large debris is blocked by the first filter screen 703. Specifically, the fan 705 on the lower surface of the limit protrusion starts to work. The switch and controller 706 control the fan 705. The energy storage power supply 707 provides power. This is existing technology and will not be described in detail here. Small debris enters the collection cylinder 702 with the air. After being blocked by the second filter screen 704, it is discharged from the opening. This can reduce the impact of the centrifugal force of the drill rod 2 on small debris splashing to the user's position and causing adverse effects on the user during operation.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
