Description

Technical Field

[0001] This utility model relates to the field of protective covers, specifically a protective cover device for an electric saw. Background Technology

[0002] The circular saw is an extremely common electric cutting tool. Its core component is a high-speed rotating toothed circular saw blade, widely used in wood processing, construction, and decoration. Whether it's cutting timber and boards on construction sites or precision grooving in furniture manufacturing, it's indispensable. With its high cutting efficiency, good straight-line accuracy, and relatively flexible operation, it has become an essential basic power tool in the modern woodworking industry.

[0003] To ensure operator safety, circular saws are typically equipped with a protective cover made of metal or high-strength plastic. The core function of this cover is to completely enclose the upper half of the saw blade when not cutting, preventing accidental contact and serious injury. During cutting operations, the cover leaves only a necessary gap at the point where the saw blade contacts the material, always providing maximum passive safety protection for the operator's hands.

[0004] During use and observation, it was found that the high-speed rotating saw blade generates a large amount of chips and dust. The protective cover has limited ability to intercept these chips, so these chips still splash out between the saw blade and the protective cover, thus contaminating the processing table and working environment, causing inconvenience during production.

[0005] Therefore, a protective cover device for chainsaws is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A protective cover device for an electric saw, comprising a processing table, an installation groove provided in the processing table, and a cutting tool and a connector arranged sequentially in the installation groove; the cutting tool is used to cut a template; the connector is fixed to the processing table by bolts; a protective cover body is provided on the connector; a connecting pipe is connected to one end of the protective cover body away from the connector; a negative pressure supply device is connected to the end of the connecting pipe; the other end of the connecting pipe is set towards the cutting tool; by setting the connecting pipe, the protective cover body can absorb and collect the powder and debris generated by the cutting tool through negative pressure, so as to reduce the pollution of these debris to the processing table and the working environment.

[0008] Preferably, the protective cover body and the connector are slidably connected; a screw is threaded onto the protective cover body, and the end of the screw abuts against the surface of the connector; a base is rotatably connected inside the protective cover body; a stop block is fixedly connected to the top of the base; both the stop block and the protective cover body have mounting holes, and pins are provided in the mounting holes; a filter assembly is provided between the connecting pipe and the negative pressure supply device; the protective cover body is transparent; by setting the base, the operator can flexibly control the base by inserting and removing the pins, realizing the collection and discharge of debris by the base.

[0009] Preferably, a fixing plate is fixed to the inner wall of the protective cover body; the fixing plate is located above the base; multiple gear teeth are fixed to the bottom of the fixing plate; one side of the gear teeth is inclined; by setting the fixing plate and gear teeth, debris can pass through the gear teeth during the process of entering the protective cover body and connecting pipe under negative pressure. Some debris can adhere to the inclined surface of the gear teeth under the obstruction of the gear teeth, which can reduce the burden of the filter assembly on debris interception. When the negative pressure stops, these debris can fall from the surface of the gear teeth and fall into the interior of the base. The length of the base should cover all the gear teeth to ensure the effect of the above-mentioned debris falling from the gear teeth to the base.

[0010] Preferably, a first magnet is fixed to the side of the protective cover body away from the connector via a mounting plate; a second magnet is fixed to the side of the base away from the stop block; the second magnet and the first magnet are magnetically attracted to each other; by setting the first magnet and the second magnet, after the operator pulls out the pin, the base can be in an over-deflected state under the magnetic attraction of the first magnet and the second magnet, that is, the angle between the base and the inner wall of the protective cover body is an obtuse angle, which can effectively discharge the debris collected in the base.

[0011] Preferably, the filter assembly includes a filter fixedly installed at the end of the connecting pipe; the filter contains a filter element; the other end of the filter is connected to a negative pressure supply device; the filter and the connecting pipe are connected by threads, and the filter and the negative pressure supply device can also be connected by threads, so that the filter and the filter element can be disassembled and replaced together.

[0012] Preferably, the side of the stop block closest to the connector is inclined; by setting one side of the stop block to be inclined, the obstruction of debris when it enters the body of the protective cover can be reduced, and the debris can be limited by the other end of the stop block after the negative pressure stops, thus ensuring the base's ability to collect debris.

[0013] The advantages of this utility model are: 1. The protective cover device for an electric saw described in this utility model, by setting a connecting pipe, allows the protective cover body to adsorb and collect powder and debris generated during cutting by the blade through negative pressure, thereby reducing the pollution of these debris to the processing table and working environment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1 to 5As shown in the embodiment of this utility model, a protective cover device for an electric saw includes a processing table 1. The processing table 1 has a mounting groove, in which a cutting tool 12 and a connecting member 13 are sequentially arranged. The cutting tool 12 is used to cut a template. The connecting member 13 is fixed to the processing table 1 by bolts. A protective cover body 14 is provided on the connecting member 13. A connecting pipe 15 is connected to one end of the protective cover body 14 away from the connecting member 13. A negative pressure supply device is connected to one end of the connecting pipe 15. The other end of the connecting pipe 15 faces the cutting tool 12. During operation, the operator can manually push the template to be processed, causing it to contact the cutting tool 12 and be cut by it. The cutting tool 12 is driven by a motor. The protective cover body 14 can prevent the operator's body parts from coming into contact with the cutting tool 12. Since the cutting tool 12 will generate a large amount of powder and debris during the cutting process of the template, and the protective cover body 14 only has the function of interception and it is difficult to collect the debris, the connecting pipe 15 can be connected to a negative pressure supply device before work, which can be a vacuum cleaner or a blower. Considering the presence of powder and debris, a vacuum cleaner is preferred. It is worth mentioning that the end of the connecting pipe 15 can be a standard interface, such as a threaded interface, which is not specifically limited here. By setting the connecting pipe 15, the protective cover body 14 can adsorb and collect the powder and debris generated by the cutting tool 12 during cutting through negative pressure, so as to reduce the pollution of these debris to the processing table 1 and the working environment.

[0021] Please see Figures 3 to 5 As shown, the protective cover body 14 and the connector 13 are slidably connected; a screw 23 is threadedly connected to the protective cover body 14, and the end of the screw 23 abuts against the surface of the connector 13; a base 2 is rotatably connected inside the protective cover body 14; a stop 24 is fixedly connected to the top of the base 2; both the stop 24 and the protective cover body 14 have mounting holes, and pins 22 are provided in the mounting holes; a filter assembly is provided between the connecting pipe 15 and the negative pressure supply equipment; the protective cover body 14 is transparent; when a blower or other negative pressure supply equipment that does not collect debris is used... When the equipment is in operation, a filter assembly should be installed at the end of the connecting pipe 15 to intercept solid debris. After the blower stops working, this debris will fall into the base 2 under gravity through the connecting pipe 15. The base 2 can collect the debris through the stop block 24 and the inner wall of the protective cover body 14. When it is determined by observing the protective cover body 14 that debris needs to be removed from the base 2, the screw 23 can be loosened, the protective cover body 14 moved upwards a certain distance, the screw 23 tightened, and then the pin 22 pulled out. This allows the base 2 to deflect under gravity and empty its internal debris. Figure 4 As shown, during the process, the operator can collect the poured-out debris through the container; by setting up the base 2, the operator can flexibly control the base 2 by inserting and removing the pin 22, so as to realize the collection and discharge of debris by the base 2.

[0022] Please see Figure 4 As shown, a fixing plate 3 is fixedly connected to the inner wall of the protective cover body 14; the fixing plate 3 is located above the base 2; multiple gear teeth 32 are fixedly connected to the bottom of the fixing plate 3; one side of the gear teeth 32 is inclined; by setting the fixing plate 3 and the gear teeth 32, debris can pass through the gear teeth 32 during the process of entering the protective cover body 14 and the connecting pipe 15 under negative pressure. Some debris can adhere to the inclined surface of the gear teeth 32 under the obstruction of the gear teeth 32, which can reduce the burden of the filter assembly on debris interception. When the negative pressure stops, these debris can fall from the surface of the gear teeth 32 and fall into the interior of the base 2. The length of the base 2 should cover all the gear teeth 32 to ensure the effect of the above-mentioned debris falling from the gear teeth 32 to the base 2.

[0023] Please see Figure 3 and Figure 4 As shown, a first magnet 4 is fixed to the side of the protective cover body 14 away from the connector 13 via a mounting plate; a second magnet 42 is fixed to the side of the base 2 away from the stop block 24; the second magnet 42 and the first magnet 4 are magnetically attracted to each other; by setting the first magnet 4 and the second magnet 42, after the operator pulls out the pin 22, the base 2 can be in an over-deflected state under the magnetic attraction of the first magnet 4 and the second magnet 42, that is, the angle between it and the inner wall of the protective cover body 14 is an obtuse angle, which can effectively discharge the debris collected in the base 2.

[0024] Please see Figure 4 As shown, the filter assembly includes a filter 5 fixedly installed at the end of the connecting pipe 15; the filter 5 contains a filter element 52; the other end of the filter 5 is connected to a negative pressure supply device; the filter 5 and the connecting pipe 15 are connected by a thread, and the filter 5 and the negative pressure supply device can also be connected by a thread, so that the filter 5 and the filter element 52 can be disassembled and replaced together.

[0025] Please see Figure 3 and Figure 4 As shown, the side of the baffle 24 closest to the connector 13 is inclined. By setting one side of the baffle 24 to be inclined, the obstruction of the baffle 24 when the debris enters the protective cover body 14 can be reduced. At the same time, after the negative pressure stops, the debris can be limited by the other end of the baffle 24, ensuring the base 2's ability to collect debris.

[0026] Working principle: The operator can manually push the template to be processed, bringing it into contact with the cutting tool 12 for cutting. The cutting tool 12 is driven by a motor. The protective cover body 14 prevents the operator's body parts from coming into contact with the cutting tool 12. Since the cutting tool 12 generates a large amount of powder and debris during the cutting process, and the protective cover body 14 only has an interception function and cannot collect the debris, the connecting pipe 15 can be connected to a negative pressure supply device before operation. Specifically, it can be a vacuum cleaner or a blower. Considering the presence of powder and debris, a vacuum cleaner is preferred. It is worth mentioning that the end of the connecting pipe 15 can be a standard interface, such as a threaded interface. No specific limitations are made here; when using a blower or other negative pressure supply equipment that does not collect debris, a filter assembly should be installed at the end of the connecting pipe 15 to intercept solid debris. When the blower stops working, these debris can fall into the interior of the base 2 under gravity through the connecting pipe 15. The base 2 can collect the debris through the stop 24 and the inner wall of the protective cover body 14. When it is determined by observing the protective cover body 14 that the debris inside the base 2 needs to be removed, the screw 23 can be loosened and the protective cover body 14 moved upward a certain distance, the screw 23 can be tightened and the pin 22 can be pulled out, so that the base 2 can be deflected under gravity and the debris inside can be poured out. During the process, the operator can collect the poured-out debris using a container. By setting up the fixing plate 3 and the toothed wheel 32, the debris can pass through the toothed wheel 32 as it enters the protective cover body 14 and connecting pipe 15 under negative pressure. Some debris can adhere to the inclined surface of the toothed wheel 32 due to the obstruction effect, reducing the burden on the filter assembly for debris interception. When the negative pressure stops, these debris can fall from the surface of the toothed wheel 32 and into the interior of the base 2. The length of the base 2 should cover all the toothed wheel 32 to ensure the effective falling of the debris from the toothed wheel 32 to the base 2. By setting up the first magnet 4 and the second magnet 42, the operator can pull out the pin 22. Afterwards, the base 2 can be in an over-deflected state under the magnetic attraction of the first magnet 4 and the second magnet 42, that is, the angle between it and the inner wall of the protective cover body 14 is an obtuse angle, which can effectively discharge the debris collected in the base 2; the filter 5 and the connecting pipe 15 are connected by threads, and the filter 5 and the negative pressure supply device can also be connected by threads. This setting allows the filter 5 together with the filter element 52 to be disassembled and replaced; by setting one side of the baffle 24 to be inclined, the obstruction of the baffle 24 when the debris enters the interior of the protective cover body 14 can be reduced. At the same time, after the negative pressure stops, the debris can be limited by the other end of the baffle 24, ensuring the base 2's ability to collect debris.

[0027] 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.
