Description
Technical Field
[0001] This utility model relates to the field of protective devices, and in particular to a front hard protective hinge device for a sliding plate. Background Technology
[0002] The front hard guard device of the slide is installed in front of the equipment slide to prevent chips, splashes and other debris generated during processing from causing injury to operators. It can also prevent foreign objects from entering critical parts of the equipment and affecting its normal operation.
[0003] Related technologies such as front hard protection devices for the trailer Figure 1 As shown, the device includes a protective cover hinged to the frame and a motor that drives the protective cover to rotate. When the protective cover rotates downwards to the protective state, it can block the waste from the processing, but this also causes the blocked waste to accumulate directly inside the protective cover. When the protective cover is opened, the waste accumulated inside the protective cover will be poured out. If the operator needs to stand under the protective cover to inspect the equipment or workpiece, the waste residue on the inner wall of the protective cover may fall off, which can easily cause scratches and damage to the operator's clothing and skin. Utility Model Content
[0004] To reduce the impact of residual debris inside the protective cover on operators, this application provides a front hard protective hinge device for the slide.
[0005] The technical solution of the front hard protection hinge device for a sliding plate provided in this application is as follows: A front hard protection hinge device for a sliding plate includes a frame, a protective cover, and a motor. One end of the protective cover has a first rotating shaft, which is rotatably connected to the frame. The motor is fixedly mounted on the frame, and the output shaft of the motor is coaxially fixed to the first rotating shaft. It also includes a movable baffle, a mounting block, a second rotating shaft, and a first driving component. The second rotating shaft is rotatably connected to the inner side of the bottom end of the protective cover. The mounting block is detachably connected to the second rotating shaft. The movable baffle is fixed to the mounting block by screws. The first driving component drives the second rotating shaft to rotate. When the protective cover is rotated to the protective state, the movable baffle rotates to the tilted state, and the bottom end of the movable baffle abuts against the frame. The movable baffle is used to collect waste chips. When the protective cover is rotated to the open state, the movable baffle rotates to the horizontal state.
[0006] By adopting the above technical solution, in the protective state, the movable baffle is tilted to block and collect waste debris, reducing the chance of debris directly splashing onto the inner wall of the protective cover. When the protective cover is rotated to the open state, the movable baffle simultaneously switches to a horizontal state. At this time, the waste debris remaining on the movable baffle will remain stably on the horizontal movable baffle and will not fall directly when the protective cover is opened, completely eliminating the risk of waste debris causing scratches and injuries to the clothing and skin of the operators below. At the same time, the movable baffle is detachably connected to the second rotating shaft via a mounting block, which facilitates the cleaning, maintenance, or replacement of the movable baffle in the future, further improving the practicality and service life of the device.
[0007] Preferably, the second rotating shaft has a spline in the middle, and the mounting block has a keyway that is interference-fitted with the spline.
[0008] By adopting the above technical solution and utilizing the interference fit between the spline and the keyway, a detachable connection between the second rotating shaft and the mounting block is achieved.
[0009] Preferably, the driving component includes a reset component, a pull rope, a first block, and a second block. The reset component is used to drive the movable baffle to rotate to an inclined state. The first block is fixedly mounted on the inner wall of the protective cover, and the second block is fixedly mounted on the frame. The second block is located directly below the first rotating shaft. A through hole is provided on the first block. One end of the pull rope is fixed and wound around the second rotating shaft, and the other end of the pull rope is fixed to the second block after passing through the through hole. When the protective cover rotates to the protective state, the first block is located below the second block, and the distance between the first block and the second block is L1. When the protective cover rotates to the open state, the first block is located above the first rotating shaft, and the distance between the first block and the second block is L2. The distance L2 is greater than L1.
[0010] By adopting the above technical solution, the movable baffle automatically switches states through mechanical linkage, eliminating the need for additional power components and reducing costs and energy consumption. When the protective cover rotates, the tension of the pull rope and the coordination of the reset component drive the movable baffle to automatically switch between an inclined receiving state and a horizontal anti-fall state, making operation convenient and highly reliable.
[0011] Preferably, the second rotating shaft and the second block are provided with mounting holes, and the two ends of the pull rope pass through the two mounting holes respectively and are tied to the second rotating shaft and the second block respectively.
[0012] By adopting the above technical solution, the two ends of the pull rope are passed through the mounting holes and tightened to form a stable closed loop, preventing loosening during long-term use and ensuring stable transmission of driving force. Furthermore, replacing the pull rope does not require disassembling complex components, simplifying the maintenance process and reducing maintenance costs.
[0013] Preferably, the movable baffle is fixed to the bottom of the mounting block by screws.
[0014] By adopting the above technical solution, the movable baffle is fixed below the mounting block, preventing the connecting parts from being exposed and reducing the accumulation and jamming of waste. At the same time, it ensures a tighter fit between the movable baffle and the frame, reducing waste leakage, and making the installation and removal of the movable baffle more convenient and safer.
[0015] Preferably, the reset component includes a torsion spring and a stop block. The torsion spring is coaxially sleeved on the second rotating shaft. The two ends of the torsion spring abut against the movable baffle and the inner wall of the protective cover, respectively. The stop block is fixed to the bottom surface of the mounting block. When the stop block abuts against the inner wall of the protective cover, the movable baffle is in an inclined state.
[0016] By adopting the above technical solution, the torsion spring provides a stable restoring force, driving the movable baffle to remain tilted in the protective state; the stop block precisely limits the tilt angle of the movable baffle and also provides support, ensuring the stability of the waste chip receiving function.
[0017] Preferably, the protective cover has through holes on both sides for the second rotating shaft to pass through, and support blocks are fixed to the outer sides of the protective cover by screws. Bearings are installed on the support blocks, and the two ends of the second rotating shaft are respectively interference-fitted with the inner rings of the two bearings.
[0018] By adopting the above technical solution, the support block and bearing provide low-friction support for the second rotating shaft, converting sliding friction into rolling friction. This also balances the force on the rotating shaft, extends its service life, and improves the stability of the device.
[0019] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model forms a linkage structure of "protective cover + movable baffle", which effectively solves the problem of waste falling and injuring people in traditional devices; in the protective state, the inclined movable baffle receives the waste; in the open state, the movable baffle turns to horizontal to prevent waste from falling. 2. This utility model utilizes mechanical linkage to achieve automatic switching of the movable baffle, eliminating the need for additional power components and reducing costs and energy consumption. When the protective cover rotates, the tension of the pull rope, in conjunction with the reset component, drives the movable baffle to automatically switch between an inclined support state and a horizontal anti-fall state, making operation convenient and highly reliable.

[0027] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.
[0028] This application discloses a front hard protection hinge device for a sliding plate.
[0029] Reference Figures 1-4 The sliding plate front hard protection hinge device of this embodiment includes a frame 1, a protective cover 2 and a motor 11. One end of the protective cover 2 has a first rotating shaft 21, which is rotatably connected to the frame 1. The motor 11 is fixedly mounted on the frame 1, and the output shaft of the motor 11 is coaxially fixed on the first rotating shaft 21.
[0030] Reference Figures 1-4 It also includes a movable baffle 32, a mounting block 31, a second rotating shaft 33, and a drive component 4. The second rotating shaft 33 is rotatably connected to the inner side of the bottom end of the protective cover 2. The mounting block 31 is detachably connected to the second rotating shaft 33. The movable baffle 32 is fixed to the mounting block 31 by screws. The drive component 4 drives the second rotating shaft 33 to rotate.
[0031] Reference Figure 4 The two ends of the movable baffle 32 are respectively close to the inner walls of the two sides of the protective cover 2. When the protective cover 2 is rotated to the protective state, the movable baffle 32 is rotated to the tilted state, and the bottom end of the movable baffle 32 abuts against the frame 1. The movable baffle 32 is used to receive waste chips; when the protective cover 2 is rotated to the open state, the movable baffle 32 is rotated to the horizontal state.
[0032] Reference Figure 4In the protective state, the movable baffle 32 is tilted to block and collect waste debris, reducing the chance of debris directly splashing onto the inner wall of the protective cover 2. When the protective cover 2 is rotated to the open state, the movable baffle 32 simultaneously switches to a horizontal state. At this time, the waste debris remaining on the movable baffle 32 will remain stably on the horizontal movable baffle 32 and will not fall directly due to the opening of the protective cover 2, completely eliminating the risk of waste debris causing scratches and damage to the clothing and skin of the operators below. At the same time, the movable baffle 32 is detachably connected to the second rotating shaft 33 via the mounting block 31, which facilitates the cleaning, maintenance, or replacement of the movable baffle 32 in the future, further improving the practicality and service life of the device.
[0033] Reference Figure 4 and Figure 5 The second rotating shaft 33 has a spline 331 in the middle, and the mounting block 31 has a keyway 311 that is interference-fitted with the spline 331. The interference fit between the spline 331 and the keyway 311 enables a detachable connection between the second rotating shaft 33 and the mounting block 31.
[0034] Reference Figures 2-6 The driving component 4 includes a reset component, a pull rope 41, a first block 42, and a second block 43. The reset component is used to drive the movable baffle 32 to rotate to an inclined state. The first block 42 is fixedly installed on the inner wall of the protective cover 2, and the second block 43 is fixedly installed on the frame 1. The second block 43 is located directly below the first rotating shaft 21. A through hole is provided on the first block 42. One end of the pull rope 41 is fixed and wound around the second rotating shaft 33, and the other end of the pull rope 41 is fixed to the second block 43 after passing through the through hole. When the protective cover 2 rotates to the protective state, the first block 42 is located below the second block 43, and the distance between the first block 42 and the second block 43 is L1. When the protective cover 2 rotates to the open state, the first block 42 is located above the first rotating shaft 21, and the distance between the first block 42 and the second block 43 is L2. L2 is greater than L1.
[0035] Reference Figures 2-6 The movable baffle 32 automatically switches states via mechanical linkage, eliminating the need for additional power components and reducing costs and energy consumption. When the protective cover 2 rotates, the movable baffle 32 automatically switches between tilted support and horizontal anti-fall states through the tension of the pull rope 41 and the coordination of the reset component, making operation convenient and highly reliable.
[0036] Reference Figures 2-6 Mounting holes 44 are provided on the second rotating shaft 33 and the second block 43. The two ends of the pull rope 41 pass through the two mounting holes 44 respectively and are tied to the second rotating shaft 33 and the second block 43 respectively.
[0037] Reference Figures 2-5The two ends of the pull rope 41 are passed through the mounting holes 44 and fastened to form a stable closed loop, preventing loosening during long-term use and ensuring stable transmission of driving force. Furthermore, replacing the pull rope 41 does not require disassembling complex components, simplifying the maintenance process and reducing maintenance costs.
[0038] Reference Figure 4 and Figure 6 The movable baffle 32 is fixed to the bottom of the mounting block 31 with screws. Fixing the movable baffle 32 to the bottom of the mounting block 31 prevents exposed connecting parts and reduces waste accumulation and jamming. It also ensures a tighter fit between the movable baffle 32 and the frame 1, reducing waste leakage, and makes the installation and removal of the movable baffle 32 more convenient and safer.
[0039] Reference Figure 1 The reset component includes a torsion spring 45 and a stop block 46. The torsion spring 45 is coaxially sleeved on the second rotating shaft 33, and its two ends abut against the movable baffle 32 and the inner wall of the protective cover 2, respectively. The stop block 46 is fixed to the bottom surface of the mounting block 31. When the stop block 46 abuts against the inner wall of the protective cover 2, the movable baffle 32 is in an inclined state. There are two torsion springs 45, which are located on both sides of the mounting block 31.
[0040] Reference Figures 3-6 The torsion spring 45 provides a stable restoring force, driving the movable baffle 32 to remain tilted in the protective state; the stop block 46 precisely limits the tilt angle of the movable baffle 32 and also provides support to ensure the stability of the waste chip receiving function.
[0041] Reference Figure 1 and Figure 5 The protective cover 2 has through holes on both sides for the second rotating shaft 33 to pass through. Support blocks 51 are fixed to the outer sides of the protective cover 2 by screws. Bearings 52 are installed on the support blocks 51. The two ends of the second rotating shaft 33 are respectively interference-fitted with the inner rings of the two bearings 52.
[0042] Reference Figure 1 and Figure 5 The support block 51 and bearing 52 provide low-friction support for the second rotating shaft 33, converting sliding friction into rolling friction. At the same time, it balances the force on the rotating shaft, extends its service life, and improves the stability of the device.
[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
