Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to an electric drill dust collector and an electric drill device. Background Art

[0002] Electric drill dust collectors are usually used in conjunction with electric drills. Electric drills generate a lot of dust and debris when performing operations such as drilling. Electric drill dust collectors are installed on electric drills to collect the dust and debris generated during the operation of the electric drill, preventing dust from flying and keeping the working environment clean. At the same time, it also reduces the impact of dust on the health of operators.

[0003] Electric drill dust collectors in the prior art are mainly divided into three categories. One is a single dust collecting telescopic cylinder. Correspondingly, the single dust collecting telescopic cylinder is covered on the drill bit of the electric drill. When in use, the dust collecting telescopic cylinder will rotate with the drill bit. The dust collecting telescopic cylinder may shake, deform or even fall off, which is not only prone to dust leakage and affects the dust collection effect, but may also pose a threat to the safety of the operator.

[0004] The second type is a dust collecting telescopic cylinder plus a fixed shell. The fixed shell is installed on the drill bit of the electric drill, and the dust collecting telescopic cylinder is installed on the fixed shell. When in use, the fixed shell and the dust collecting telescopic cylinder will rotate with the drill bit, affecting the dust prevention effect.

[0005] The third type is a dust collecting telescopic cylinder plus a fixed shell plus a bearing. The bearing is easily clogged with dust, which makes the rotation unsmooth or even blocked, affecting the operation.

[0006] Based on this, the present invention provides a novel electric drill dust collector and an electric drill device to overcome the defects in the prior art. Utility Model Content

[0007] One purpose of the utility model is to provide an electric drill dust collector, in which the fixed base of the electric drill dust collector does not rotate when the electric drill is working, thereby ensuring the relative fixation of the dust collecting barrel and the drilling position, and avoiding the influence of the dust collecting effect and the operational safety due to the rotation of the dust collecting barrel; at the same time, the drill bit drives the rotating plug to rotate in the fixed base, forming a dynamic seal, and the rotating plug and the drill bit are closely matched, which can effectively seal the dust, prevent the dust from escaping from the connection between the drill bit and the fixed base, and prevent the dust from entering the connection between the drill bit and the drill body, thereby affecting the service life of the electric drill.

[0008] The utility model adopts the following technical solution: an electric drill dust collector for installation on an electric drill, comprising:

[0009] A fixed base, wherein one end of the fixed base is provided with a through hole;

[0010] A rotating plug is installed in the through hole of the fixed base, and a through hole is defined in the middle of the rotating plug, wherein the drill bit of the electric drill is mounted in the through hole; wherein the rotating plug has an I-shaped cross-section, comprising a main body, and first and second limiting portions located at opposite ends of the main body, the first and second limiting portions respectively abutting against the upper and lower surfaces of the fixed base;

[0011] The dust collecting barrel is a hollow structure with openings at both ends, which is installed on the fixed base and is used to accommodate the drill bit on the electric drill.

[0012] Furthermore, a slot is provided at the other end of the fixed base for limiting the protruding objects on the electric drill.

[0013] Furthermore, a tightening adjustment component is installed on the fixed base, and the lifting block in the tightening adjustment component is opposite to the position of the card slot and is used to tighten the protruding object in the card slot.

[0014] Furthermore, the card slot is a long strip-shaped card slot.

[0015] Furthermore, a protruding structure is formed on one side of the first limiting portion and / or the second limiting portion close to the main body.

[0016] Furthermore, the protrusion structure is provided in plurality and arranged in a spiral shape along the circumference of the rotary plug.

[0017] Furthermore, the dust collecting cylinder is a retractable bellows cylinder.

[0018] Furthermore, both ends of the dust collecting barrel are provided with mutually matching threaded structures, so as to allow the dust collecting barrel to be connected end to end and grow.

[0019] Furthermore, an annular rotating friction block is sleeved on the outer wall of the rotating plug, and the connection between the fixed base and the rotating plug is achieved through the annular rotating friction block.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] When using the electric drill dust collector of the present invention, the fixed base is first placed at the location to be drilled, and the through-hole in the rotating plug is aligned with the location to be drilled. Next, the electric drill bit is inserted through the through-hole of the rotating plug and into the dust collection barrel. No other accessories need to be installed, and assembly is simple. At this time, the electric drill is started, the drill bit rotates, and drives the rotating plug to rotate in the fixed base. Dust and debris generated during the operation of the electric drill are collected by the dust collection barrel, preventing the fixed base from rotating synchronously during the rotation of the drill bit. The fixed base does not rotate during the operation of the electric drill, ensuring that the dust collection barrel is relatively fixed to the drilling location, and preventing the dust collection effect and operational safety affected by the rotation of the dust collection barrel.

[0022] At the same time, the drill bit drives the rotating plug to rotate within the fixed base, forming a dynamic seal. The rotating plug and the drill bit work closely together to effectively seal out dust, preventing it from escaping from the connection between the drill bit and the fixed base and from entering the connection between the drill bit and the drill body, which could affect the life of the electric drill. Effective dust prevention measures can reduce wear and damage to the internal components of the electric drill, extending the service life of the electric drill and reducing maintenance costs.

[0023] Furthermore, the first and second stoppers at either end of the main body abut against the upper and lower surfaces of the fixed base, respectively, effectively limiting the axial movement of the rotary plug, ensuring it will not escape from the fixed base during operation and guaranteeing the proper functioning of the dust collector. The "I"-shaped design also increases the structural strength and stability of the rotary plug. When the drill bit rotates, the rotary plug can withstand a certain amount of torque and centrifugal force, making it less susceptible to deformation or damage. Furthermore, the close contact between the first and second stoppers and the fixed base further enhances the sealing performance of the rotary plug, preventing dust from leaking from the edges.

[0024] In summary, the electric drill dust collector can effectively collect dust and debris generated by the electric drill during operation through the synergistic effect of components such as the fixed base, the rotating plug, and the dust collection barrel, thereby improving the cleanliness of the working environment, protecting the health of the operator, and extending the service life of the electric drill.

[0025] Another object of the present utility model is to provide an electric drill device, which includes an electric drill and an electric drill dust collector installed at the front end of the electric drill, wherein the electric drill dust collector is the above-mentioned electric drill dust collector.

DETAILED DESCRIPTION

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following is combined with Figures 1 to 4 And specific embodiments, the utility model is discussed in detail:

[0034] like Figure 1-4 As shown, the utility model provides an electric drill dust collector, which is used to be installed on an electric drill to collect dust and debris generated during the operation of the electric drill, and includes:

[0035] A fixed base 1, one end of which is provided with a through hole 10;

[0036] The rotary plug 2 is installed in the through hole 10 of the fixed base 1. A through hole 20 is provided in the middle of the rotary plug 2. The drill bit on the electric drill is installed in the through hole 20 to achieve a tight fit between the rotary plug 2 and the drill bit. When working, the drill bit of the electric drill is inserted into the rotary plug 2 and drives the rotary plug 2 to rotate in the fixed base 1. Figure 4 As shown, the cross-section of the rotary plug 2 is an I-shaped body 21, and a first limiting portion 22 and a second limiting portion 23 are respectively located at both ends of the body 21. The first limiting portion 22 and the second limiting portion 23 are respectively abutted against the upper and lower surfaces of the fixed base 1 to play a limiting role.

[0037] The dust collecting barrel 3 is a hollow structure with openings at both ends, mounted on the fixed base 1 and used to accommodate the drill bit on the electric drill.

[0038] When using the electric drill dust collector of the present invention, the fixed base 1 is first placed at the position to be drilled, and the through hole 20 in the rotary plug 2 is aligned with the position to be drilled. Next, the electric drill bit is passed through the through hole 20 of the rotary plug 2 and then extended into the dust collection barrel 3. No other accessories need to be installed, and the assembly is simple. At this time, the electric drill is started, the drill bit rotates, and drives the rotary plug 2 to rotate in the fixed base 1. The dust and debris generated during the operation of the electric drill are collected by the dust collection barrel 3, preventing the fixed base 1 from rotating synchronously during the rotation of the drill bit. The fixed base 1 does not rotate when the electric drill is working, thereby ensuring that the dust collection barrel 3 is relatively fixed to the drilling position, and preventing the dust collection effect and operational safety affected by the rotation of the dust collection barrel 3.

[0039] At the same time, the drill bit drives the rotating plug 2 to rotate within the fixed base 1, forming a dynamic seal. The rotating plug 2 and the drill bit work closely together, effectively sealing out dust, preventing it from escaping from the connection between the drill bit and the fixed base 1 and from entering the connection between the drill bit and the drill body, which could affect the service life of the electric drill. Effective dust prevention measures can reduce wear and damage to the internal components of the electric drill, thereby extending the service life of the electric drill and reducing maintenance costs.

[0040] Furthermore, the first limiting portion 22 and the second limiting portion 23 at each end of the main body 21 respectively abut against the upper and lower surfaces of the fixed base 1, effectively limiting the axial movement of the rotary plug 2 and ensuring that the rotary plug 2 does not escape from the fixed base 1 during operation, thereby ensuring the normal operation of the dust collector. Furthermore, the "I"-shaped design increases the structural strength and stability of the rotary plug 2. When the drill bit rotates and drives the rotary plug 2 to rotate, it can withstand a certain amount of torque and centrifugal force and is not easily deformed or damaged. Furthermore, the close contact between the first limiting portion 22 and the second limiting portion 23 and the fixed base 1 further enhances the sealing performance of the rotary plug 2, preventing dust from leaking from the edges.

[0041] In summary, the electric drill dust collector, through the coordinated action of the fixed base 1, rotating plug 2, and dust collection barrel 3, can effectively collect dust and debris generated during the operation of the electric drill, thereby improving the cleanliness of the working environment, protecting the health of the operator, and extending the service life of the electric drill. Furthermore, the electric drill dust collector, consisting of the fixed base 1, rotating plug 2, and dust collection barrel 3, has a simple structure and is easy to install.

[0042] Further, such as Figure 1 、 2In some specific embodiments shown in FIG. 3 , a slot 11 is defined at the other end of the fixed base 1 to limit the position of protruding objects on the electric drill, ensuring a more stable position of the electric drill during operation and preventing unnecessary movement of the electric drill during drilling, thereby improving drilling accuracy. Specifically, in this embodiment, the slot 11 is an elongated slot to accommodate protruding objects on different electric drills, increasing the versatility of the dust collector, making it suitable for a variety of different electric drill models and improving the practicality of the dust collector.

[0043] Correspondingly, a tightening adjustment component 4 is also installed on the fixed base 2. The top block 40 in the tightening adjustment component 4 is opposite to the position of the card slot 11 and is used to tighten the protrusion in the card slot 11. In the present utility model, the protrusion can be a limit ruler or other objects, which is not specifically limited in the present utility model. At the same time, the specific structure of the tightening adjustment component 4 is not limited in the present utility model, as long as the corresponding protrusion can be tightened by the top block 40. For example, in the present embodiment, the tightening adjustment component 4 includes a rotating screw 41 rotatably installed on the fixed base 2, a knob 42 installed at one end of the rotating screw 41, a nut 43 installed at the other end of the rotating screw 41, and a top block 40 installed on the nut, and the knob 42 is located on the outside of the fixed base 2. During operation, rotating the knob 42 drives the rotating screw 41 to rotate, which is converted into a linear motion of the nut 43 along the rotating screw 41, thereby driving the sliding of the top block 40 to achieve tightening of the protrusion.

[0044] The combination of rotating screw 41, knob 42, nut 43, and ejector block 40 allows for adjustable tightening. Operators can flexibly adjust the position of ejector block 40 to achieve optimal tightening, tailored to the size and shape of the drill protrusion. This adjustability enhances the dust collector's adaptability and ease of operation.

[0045] Furthermore, in some specific embodiments, Figure 1 、 2 As shown, the fixed base 1 includes an upper base 12 and a lower base 13, and the upper base 12 and the lower base 13 are plug-connected, and a receiving cavity is formed between the upper base 12 and the lower base 13, and the tightening adjustment component 4 is correspondingly installed in the receiving cavity between the upper base 12 and the lower base 13. The tightening adjustment component 4 is installed in the receiving cavity between the upper base 12 and the lower base 13, so that the structure of the entire dust collector is more compact. It should be noted that in the present invention, the specific plug-in connection method between the upper base 12 and the lower base 13 is not limited, and can be designed by those skilled in the art according to actual conditions. Since the upper base 12 and the lower base 13 adopt a plug-in connection method, when the tightening adjustment component 4 needs to be maintained or repaired, the upper base 12 and the lower base 13 can be easily separated, and the tightening adjustment component 4 can be easily taken out for inspection and repair.

[0046] Furthermore, in some specific embodiments, the rotating plug 2 is a rubber plug. The rubber plug has good elasticity and flexibility, and can fit tightly against the drill bit and fixed base 1, forming an effective seal and effectively blocking dust, thereby achieving a good dust-proof effect. Furthermore, the soft rubber material can reduce friction between the drill bit and the dust collector, reducing wear on the drill bit and fixed base 1, and extending the service life of the drill bit and fixed base 1.

[0047] Furthermore, a protruding structure 24 is formed on one side of the first limiting portion 22 and / or the second limiting portion 23 close to the main body portion 21, and a protruding structure 24 is formed on at least one side of the two limiting portions. The protruding structure 24 can scrape away dust during rotation, effectively preventing dust from accumulating and clogging around the rotating plug, ensuring that the rotating plug can rotate smoothly without affecting the normal operation of the dust collector; at the same time, timely cleaning of dust can reduce the entry of dust into other parts, further improving the overall dust-proof effect of the dust collector.

[0048] In this embodiment, the protrusion structure 24 is a long strip of protrusions, and there are four of them. The four long strip protrusions are arranged in a spiral shape along the circumference of the rotating plug 2. The long strip protrusions can have a larger contact area with the dust during rotation, thereby improving the dust scraping efficiency. The spiral arrangement allows the protrusions to more comprehensively cover the area around the rotating plug during rotation, ensuring that dust from all directions can be effectively scraped away. At the same time, the long strip protrusions arranged in a spiral shape can generate a certain airflow guidance effect during rotation, helping to guide dust into the dust collection barrel 3 and improve the dust collection effect.

[0049] Of course, an annular rotating friction block 5 can also be installed on the outer wall of the rotating plug 2 to achieve the connection between the fixed base 1 and the rotating plug 2, thereby reducing direct wear on the rotating plug 2 and the fixed base 1, helping to extend the service life of the rotating plug 2 and the fixed base 1, and reducing the maintenance cost of the dust collector. At the same time, the material of the friction block usually has a certain degree of wear resistance and corrosion resistance, which can adapt to different working environments and further improve the durability of the dust collector.

[0050] Preferably, the annular rotating friction block 5 is divided into a pair of semicircular rotating friction blocks, which are rotatably connected to the fixed base 1. Compared with the integral annular rotating friction block 5, the semicircular rotating friction blocks are easier and faster to disassemble, reducing maintenance time and workload.

[0051] Furthermore, in some specific embodiments, Figure 1As shown, the dust collection canister 3 is a retractable bellows. It can be adjusted to accommodate drill bits of varying lengths. Whether operating with short or long drill bits, the dust collection canister 3 effectively covers the drill bit's working area, maximizing dust and debris collection. Furthermore, when the dust collector is not in use, the dust collection canister 3 can be retracted to a smaller length, minimizing space and making it convenient for storage and portability.

[0052] More specifically, the dust collection bin 3 is provided with matching threaded structures at both ends, allowing the bins 3 to be connected end to end to extend to accommodate drill bits of varying lengths. Specifically, when a drill bit is too long for a single bin 3 to meet the requirements, the bin 3 can be extended by connecting one end of one bin 3 to the other using the threaded structure to accommodate drill bits of varying lengths. This ensures that during drill operation, regardless of drill bit length, a bin 3 of appropriate length will be available to effectively collect dust and debris.

[0053] Based on the aforementioned electric drill dust collector, the present invention further provides an electric drill device, characterized by comprising an electric drill and an electric drill dust collector mounted at the front end of the electric drill, wherein the electric drill dust collector is the aforementioned electric drill dust collector. This electric drill device incorporates at least all of the technical solutions of the electric drill dust collector and possesses at least all of the advantages of the electric drill dust collector, which will not be further described here.

[0054] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
