Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing protection technology, and in particular to a protection device. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the machinery manufacturing industry has also developed rapidly. In the process of machinery manufacturing, steel is usually smelted and then forged. During forging, the smelted steel is usually hammered, which can easily generate sparks. The flying sparks can easily injure the workers on site.

[0003] For example, Chinese utility model patent (CN221336474U) discloses a protective device for machinery manufacturing, which describes: "Protecting workers through a protective plate and a connecting plate, avoiding accidental injury to workers during machinery manufacturing. Workers can connect the mounting plate and the protective device according to their height, avoiding any drawbacks in the use of the protective device and increasing its usability." It also describes the technical problem that "the above-mentioned protective device for machinery manufacturing is usually not convenient for height adjustment during use. Therefore, when workers of different heights work near machinery, the protective device may be too high or too low, affecting their vision and reducing its protective effect."

[0004] In summary, existing technologies utilize protective plates and connecting plates for protection, relying on the installation and removal of mounting plates to increase or decrease the height of the protective device to accommodate workers of different heights. However, this method has the following technical problems: the installation and removal of the mounting plate for height adjustment of the protective device is limited because the height of the mounting plate is fixed, resulting in a relatively simple change in the height of the protective device before and after adjustment, and the flexibility of adjustment is not high. Therefore, this application proposes a protective device to solve the technical problems mentioned in the above-mentioned patents and provide a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide a protective device to address the aforementioned technical problems. By rotating the large screw, the overall height of the large screw and the casing can be changed, correspondingly changing the overall height of the protective casing and the fixed base. The overall height of the protective casing and the fixed base can be adjusted to various different heights, improving the flexibility of the device's use. Furthermore, during welding, sparks may be generated and splashed onto the outside of the protective casing. When the protective casing is subsequently slid into the fixed base, it will slide relative to the first scraper and the movable door, allowing the first scraper and the movable door to scrape away and clean the residue on the outside of the protective casing. Moreover, by opening the movable door, it is convenient for the operator to access the internal space of the fixed base, thereby facilitating subsequent cleaning of the space inside the fixed base.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A protective device used in machinery manufacturing.

[0008] The protection device specifically includes:

[0009] The workbench is equipped with a protective mechanism on its top, and shielding mechanisms are provided on its left and right sides respectively.

[0010] The protection mechanism includes a fixed base, a movable door, an adjustment component, and a cleaning component. The fixed base is fixedly connected to the top of the workbench, and the movable door is rotatably connected to the outer wall of the fixed base.

[0011] The shielding mechanism includes a U-shaped frame, a side baffle, a plug-in assembly, a rotating assembly, and a limiting assembly. The outer wall of the U-shaped frame is fixedly connected to the side baffle, and the U-shaped frame is movably snapped onto the outer wall of the fixed base. Multiple plug-in assemblies are provided on the U-shaped frame, and multiple limiting assemblies are respectively provided in the multiple plug-in assemblies.

[0013] In a preferred embodiment of the protective device provided by this utility model, the cleaning assembly includes a first scraper, the top of the fixed base is fixedly connected to the first scraper, and the top of the movable door is fixedly connected to a second scraper.

[0014] In a preferred embodiment of the protective device provided by this utility model, the plug-in assembly includes a sliding rod, the inner wall of the U-shaped frame is slidably connected to the sliding rod, and the outer wall of the sliding rod is fixedly connected to a T-shaped plug, which moves through the movable door and is then plugged into the fixed seat.

[0015] In a preferred embodiment of the protective device provided by this utility model, the rotating assembly includes a small screw, the inner wall of the sliding rod is threaded with the small screw, one end of the small screw located inside the sliding rod is fixedly connected to a truncated cone, the outer wall of the sliding rod is rotatably connected to a protective cover, and the protective cover and the inner wall of the sliding rod are respectively fixedly connected to magnets.

[0016] In a preferred embodiment of the protective device provided by this utility model, the limiting component includes a plug rod, the inner wall of the sliding rod is slidably connected to the plug rod, the plug rod is movably inserted into the U-shaped frame, the plug rod is slidably connected to the outer wall of the cone, the outer wall of the plug rod is fixedly connected to a fixing ring, and a spring is sleeved on the outside of the plug rod, with the two ends of the spring respectively fixedly connected to the outer wall of the fixing ring and the inner wall of the U-shaped frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The protective device provided by this utility model allows the overall height of the large screw and the casing to change by rotating the large screw, which in turn changes the overall height of the protective casing and the fixed base. The overall height of the protective casing and the fixed base can be adjusted to various different heights, improving the flexibility of the device. Furthermore, during welding, sparks may fly to the outside of the protective casing. When the protective casing is slid into the fixed base, it will slide relative to the first scraper and the movable door, and the first scraper and the movable door will scrape away and clean the residue on the outside of the protective casing. Moreover, by opening the movable door, the operator can easily access the internal space of the fixed base, thus facilitating the subsequent cleaning of the internal space of the fixed base.

[0019] The protective device provided by this utility model, by clamping the U-shaped frame onto one side of the fixed base, can then be connected to the movable door and the fixed base by relying on the T-shaped insert. This restricts the movable door from closing onto the outside of the fixed base, improving the stability of the movable door closing onto the outside of the fixed base. Furthermore, rotating the small screw allows the corresponding insert rods to be inserted into the U-shaped frame, which restricts the position of the sliding rod relative to the U-shaped frame. This not only ensures the stability of the movable door closing onto the outside of the fixed base but also restricts the movement of the U-shaped frame relative to the fixed base, ensuring the stability of the installation of the side baffle and the U-shaped frame.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] As described in the background art, the installation and removal of the mounting plate of the aforementioned device allows for height adjustment of the protection device. Since the height of the mounting plate is fixed, the corresponding height change of the protection device before and after adjustment is relatively simple, and the flexibility of adjustment is not high.

[0031] To solve this technical problem, this utility model provides a protective device that is applied to mechanical manufacturing.

[0032] For details, please refer to Figures 1-4 The protective device specifically includes:

[0033] Workbench 1, with a protective mechanism 2 on the top of the workbench 1, and shielding mechanisms 3 on the left and right sides of the protective mechanism 2 respectively.

[0034] The protection mechanism 2 includes a fixed base 4, a movable door 5, an adjustment component, and a cleaning component. The fixed base 4 is fixedly connected to the top of the workbench 1, and the movable door 5 is rotatably connected to the outer wall of the fixed base 4.

[0035] The shielding mechanism 3 includes a U-shaped frame 14, a side baffle 13, a plug-in assembly, a rotating assembly, and a limiting assembly. The side baffle 13 is fixedly connected to the outer wall of the U-shaped frame 14. The U-shaped frame 14 is movably snapped onto the outer wall of the fixed base 4. Multiple plug-in assemblies are provided on the U-shaped frame 14, and multiple limiting assemblies are respectively provided in the multiple plug-in assemblies.

[0036] The protective device provided by this utility model allows the overall height of the large screw 7 and the housing 8 to change by rotating the large screw 7, which in turn changes the overall height of the protective housing 6 and the fixed base 4. The overall height of the protective housing 6 and the fixed base 4 can be adjusted to various different heights, improving the flexibility of the device. Furthermore, during welding, sparks may fly to the outside of the protective housing 6. When the protective housing 6 is slid into the fixed base 4, it will slide relative to the first scraper 11 and the movable door 5, thereby scraping away and cleaning the residue on the outside of the protective housing 6 by the first scraper 11 and the movable door 5. Moreover, by opening the movable door 5, it is convenient for the operator to access the internal space of the fixed base 4, thereby facilitating the operator to clean the internal space of the fixed base 4.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1:

[0039] Please refer to Figures 1-4 A protective device comprising:

[0040] Workbench 1, with a protective mechanism 2 on the top of the workbench 1, and shielding mechanisms 3 on the left and right sides of the protective mechanism 2 respectively.

[0041] The protection mechanism 2 includes a fixed base 4, a movable door 5, an adjustment component, and a cleaning component. The fixed base 4 is fixedly connected to the top of the workbench 1, and the movable door 5 is rotatably connected to the outer wall of the fixed base 4. The protection mechanism 2 can block and protect sparks at various heights, reducing the risk of sparks splashing and causing injury to nearby workers.

[0042] The shielding mechanism 3 includes a U-shaped frame 14, a side baffle 13, a plug-in assembly, a rotating assembly, and a limiting assembly. The side baffle 13 is fixedly connected to the outer wall of the U-shaped frame 14. The U-shaped frame 14 is movably snapped onto the outer wall of the fixed base 4. Multiple plug-in assemblies are provided on the U-shaped frame 14, and multiple limiting assemblies are provided in each of the multiple plug-in assemblies. The shielding mechanism 3 can shield and protect both sides of the working area, and at the same time, it can provide certain limiting protection for the movable door 5 when it is closed on the fixed base 4. The minimum number of plug-in assemblies is two, and the minimum number of limiting assemblies is two.

[0043] The adjustment assembly includes a protective shell 6, a protective shell 6 slidably connected to the inner wall of the fixed base 4, a large screw 7 rotatably connected to the inner wall of the protective shell 6, a sleeve 8 fixedly connected to the lower surface of the inner wall of the fixed base 4, the large screw 7 threadedly connected to the inner wall of the sleeve 8, two fixing blocks 9 fixedly connected to the inner wall of the protective shell 6, and two positioning rods 10 fixedly connected to the inner wall of the fixed base 4. The positioning rods 10 are movably inserted into the fixing blocks 9. The adjustment assembly allows the overall height of the protective shell 6 and the fixed base 4 to be adjusted to various heights, improving the flexibility of spark shielding height adjustment.

[0044] The cleaning assembly includes a first scraper 11, which is fixedly connected to the top of the fixed base 4, and a second scraper 12 is fixedly connected to the top of the movable door 5. The cleaning assembly can scrape off and clean the particles that have solidified from sparks adhering to the outside of the protective shell 6 when the protective shell 6 slides into the fixed base 4. The cleaned particles can slide down the inclined surfaces of the first scraper 11 and the second scraper 12.

[0045] In addition, when the interior of the fixed base 4 needs to be cleaned later, the large screw 7 can be separated from the housing 8 by rotating the large screw 7. By separating the protective shell 6 from the fixed base 4, it is convenient for the operator to clean the protective shell 6 and the fixed base 4 and their respective structures separately. When the protective shell 6 is installed on the fixed base 4, the protective shell 6 slides to the inner wall of the fixed base 4, and then the movement of the protective shell 6 is restricted by the fixed base 4. As the protective shell 6 slides into the fixed base 4, the positioning rod 10 will be inserted into the fixing block 9, thereby restricting the movement of the protective shell 6 in the direction of the movable door 5, so that the large screw 7 can be accurately aligned with the top opening of the housing 8, and then the large screw 7 can be rotated into the housing 8.

[0046] Through the above structural design, the overall height of the large screw 7 and the sleeve 8 can be changed by rotating the large screw 7, which in turn changes the overall height of the protective shell 6 and the fixed base 4. The overall height of the protective shell 6 and the fixed base 4 can be adjusted to a variety of different heights. During welding, sparks may be generated and splash to the outside of the protective shell 6. When the protective shell 6 is slid into the fixed base 4, the protective shell 6 will slide relative to the first scraper 11 and the movable door 5. The first scraper 11 and the movable door 5 will then scrape and clean the residue on the outside of the protective shell 6. Furthermore, by opening the movable door 5, it is convenient for the operator to access the internal space of the fixed base 4, which facilitates the cleaning of the inside of the fixed base 4.

[0047] Example 2:

[0048] The protection device provided in Example 1 is further optimized, specifically, as follows: Figures 4-6 As shown, the plug-in assembly includes a sliding rod 16. The sliding rod 16 is slidably connected to the inner wall of the U-shaped frame 14, and a T-shaped plug 15 is fixedly connected to the outer wall of the sliding rod 16. The T-shaped plug 15 moves through the movable door 5 and is plugged into the fixed seat 4. The plug-in assembly can restrict the movable door 5 to cover the outside of the fixed seat 4, and at the same time assists the U-shaped frame 14 to be installed on the outside of the fixed seat 4.

[0049] The rotating assembly includes a small screw 17, which is threaded onto the inner wall of the sliding rod 16. A cone 18 is fixedly connected to one end of the small screw 17 located inside the sliding rod 16. A protective cover 22 is rotatably connected to the outer wall of the sliding rod 16. A magnet 23 is fixedly connected to the protective cover 22 and the inner wall of the sliding rod 16, respectively. The rotating assembly can adjust the limitation of the sliding of the sliding rod 16 relative to the U-shaped frame 14.

[0050] The limiting component includes a plug rod 19, which is slidably connected to the inner wall of the sliding rod 16. The plug rod 19 is movably inserted into the U-shaped frame 14 and slidably connected to the outer wall of the frustum 18. A fixing ring 20 is fixedly connected to the outer wall of the plug rod 19, and a spring 21 is sleeved on the outside of the plug rod 19. The two ends of the spring 21 are respectively fixedly connected to the outer wall of the fixing ring 20 and the inner wall of the U-shaped frame 14. The limiting component can limit the sliding of the sliding rod 16 relative to the U-shaped frame 14.

[0051] Through the above structural design, when the side baffle 13 needs to be installed, the U-shaped frame 14 is snapped into one side of the fixed base 4, and then the T-shaped insert 15 can be inserted into the movable door 5 and the fixed base 4. At this time, the inner wall of the U-shaped frame 14 near the side baffle 13 is tightly attached to the outer wall of the fixed base 4, and the insert rod 19 is aligned with the corresponding insertion hole on the U-shaped frame 14. By rotating the small screw 17, the cone 18 moves inside the sliding rod 16, thereby squeezing multiple insert rods 19 so that the corresponding insert rods 19 are all inserted into the U-shaped frame 14, causing the corresponding springs 21 to deform. This can limit the position of the sliding rod 16 relative to the U-shaped frame 14, thereby ensuring that the movable door 5 can be installed. The stability of the movable door 5 covering the outside of the fixed base 4 can also restrict the movement of the U-shaped frame 14 relative to the fixed base 4. When it is necessary to release the restriction of the U-shaped frame 14 on the fixed base 4, the operator can rotate the small screw 17 in the opposite direction, so that the cone 18 moves inside the sliding rod 16, reducing the pressure on each insertion rod 19. Then, under the action of the spring force of the spring 21, the insertion rod 19 leaves the U-shaped frame 14, thereby releasing the sliding restriction of the sliding rod 16 relative to the U-shaped frame 14. In addition, when it is not necessary to rotate the small screw 17, the protective cover 22 can be rotated, and under the magnetic force of the two magnets 23, the protective cover 22 covers the outside of the sliding rod 16.
