Mechanical anti-pinch hand anti-joint self-locking type garbage classification throwing port device

Abstract

This utility model discloses a mechanical anti-pinch, anti-locking, reversible joint type waste sorting and disposal port device, including an opening and closing door mechanism, a top plate, and a mounting frame. The mounting frame is equipped with an opening and closing door connecting mechanism, a drive mechanism, and an overflow detection sensor. The drive mechanism of this utility model can drive the opening and closing connecting mechanism through contact, ensuring the door mechanism can open normally. However, when the door mechanism closes, it uses its own gravity to descend and close, so even if a user's hand is placed on the opening and closing door mechanism, the drive mechanism will not pinch the user. When the door is closed, tension springs are connected to the mounting frame and the connecting shaft respectively. This tension spring arrangement allows the first and second anti-locking joint connectors to be in a reverse joint state, thereby preventing the user from opening the door panel without authorization.

Description

Technical Field

[0001] This utility model relates to the technical field of waste sorting devices, specifically a mechanical anti-pinch, reverse joint, self-locking waste sorting and disposal port device. Background Technology

[0002] Trash cans are containers used to store and collect waste, and are widely used in homes, public places, commercial areas, and industrial sites. With increasing environmental awareness and the implementation of waste sorting policies, the design and function of trash cans are constantly evolving to adapt to different needs and environments.

[0003] Currently, to prevent odors from escaping, garbage bins need to be equipped with automatically opening and closing doors. Most mainstream garbage sorting and disposal devices on the market use electrically driven doors. However, in terms of component installation, the motor is usually fixed to the bracket with only a single screw or simple bolt assembly. Under the vibration generated during long-term operation, this is prone to loosening and displacement, leading to unstable power transmission. Furthermore, prolonged use can cause component damage and deformation. If deformation occurs between components after the door closes, the disposal opening may not close properly. Moreover, the power drive of existing devices is mostly directly connected, which poses a risk of hand injury if the user directly touches the door due to the continuous movement of the drive mechanism. Therefore, we propose a mechanical anti-pinch, anti-joint, self-locking garbage sorting and disposal device. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical anti-pinch, reverse joint, self-locking waste sorting and disposal port device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical anti-pinch, anti-joint, self-locking garbage sorting and disposal port device, including an opening and closing door mechanism, a top plate fixedly installed on the top of the opening and closing door mechanism, an mounting frame fixedly installed on one side of the top plate, a protective frame fixedly installed on one side of the top plate, an opening and closing door connecting mechanism for driving the opening and closing door mechanism to open on the mounting frame, a driving mechanism for driving the opening and closing door connecting mechanism to operate on the mounting frame, and an overflow detection sensor fixedly installed on the mounting frame.

[0006] Furthermore, the opening and closing door mechanism includes a door frame, connecting hinges, opening and closing door panels, and a reinforcing plate. The door frame is installed on the trash can by multiple sets of locking screws. The opening and closing door panels are rotatably connected to the door frame by multiple sets of connecting hinges. The reinforcing plate is fixedly installed on the back of the opening and closing door panels.

[0007] Furthermore, the opening and closing door connection mechanism includes a first reverse joint connector, a hinge shaft, and a second reverse joint connector. A hinge seat is fixedly installed on one side of the reinforcing plate. The first reverse joint connector is rotatably connected to the hinge seat. The end of the first reverse joint connector away from the hinge seat is hinged to the second reverse joint connector via a connecting shaft. The end of the second reverse joint connector away from the first reverse joint connector is rotatably connected to the mounting frame. A tension spring is provided between the mounting frame and the connecting shaft to make the first reverse joint connector and the second reverse joint connector exhibit a reverse joint.

[0008] Furthermore, the drive mechanism includes a drive motor, an optical axis fixing seat, a reverse joint lever, and a grooved wheel. The drive motor is fixedly installed on one side of the mounting bracket, and the output end of the drive motor is fixedly connected to a fan-shaped optical axis fixing seat. A fixing frame is fixedly installed on the optical axis fixing seat by two sets of bolts. A grooved wheel is rotatably connected to one side of the connecting shaft, and a reverse joint lever that contacts the outer wall of the grooved wheel is fixedly installed on one side of the fixing frame.

[0009] Furthermore, a placement frame is fixedly installed on one side of the door frame and outside the opening and closing door panel.

[0010] Furthermore, the door panel is made of stainless steel, and a limit sensor is provided on the mounting bracket at the position corresponding to the fan-shaped optical axis fixing seat.

[0011] Compared with the prior art, the present invention has the following advantages: The overflow detection sensor set in the present invention can detect the items inside the trash can on one side of the opening and closing mechanism, thereby preventing the trash can from accumulating too much trash and affecting the normal closing of the opening and closing mechanism. The overflow detection sensor can be set with an effective detection time, and the drive mechanism can work through contact drive of the opening and closing connection mechanism to ensure that the opening and closing mechanism can be opened normally. However, when the opening and closing mechanism is closed, it uses its own gravity to close, so even if the user's hand is placed on the opening and closing mechanism, the user will not be pinched by the drive mechanism.

[0012] When the door panel is closed, the tension springs are connected to the connecting shafts between the mounting bracket and the first and second anti-joint connectors, respectively. This tension spring configuration allows the first and second anti-joint connectors to be in an anti-joint state, thereby preventing the user from opening the door panel without authorization.

[0020] 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 protection scope of the present utility model.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a mechanical anti-pinch, anti-joint, self-locking garbage sorting and disposal port device, including an opening and closing door mechanism 1, a top plate 2 fixedly installed on the top of the opening and closing door mechanism 1, an mounting frame 14 fixedly installed on one side of the top plate 2, a protective frame 6 fixedly installed on one side of the top plate 2, an opening and closing door connecting mechanism 3 for driving the opening and closing door mechanism 1 to open on the mounting frame 14, a driving mechanism 4 for driving the opening and closing door connecting mechanism 3 to operate on the mounting frame 14, and an overflow detection sensor 5 fixedly installed on the mounting frame 14.

[0022] The overflow detection sensor 5 can detect the items inside the trash can on one side of the opening and closing mechanism 1, thereby preventing excessive accumulation of trash inside the trash can from affecting the normal closing of the opening and closing mechanism 1. The overflow detection sensor 5 can be set to a 10-second effective detection duration. The drive mechanism 4 can drive the opening and closing connection mechanism 3 through contact to ensure that the opening and closing mechanism 1 can be opened normally. However, when the opening and closing mechanism 1 is closed, it will close by its own gravity. This way, even if the user's hand is placed on the opening and closing mechanism 1, the user will not be pinched by the drive mechanism 4.

[0023] Please see Figure 1 and Figure 2 The door opening and closing mechanism 1 includes a door frame 7, connecting hinges 8, opening and closing door panel 9, and reinforcing plate 11. The door frame 7 is installed on the trash can by multiple sets of locking screws. The opening and closing door panel 9 is rotatably connected to the door frame 7 by multiple sets of connecting hinges 8. The opening and closing door panel 9 is made of stainless steel. The reinforcing plate 11 is fixedly installed on the back of the opening and closing door panel 9.

[0024] The door panel 9 can be rotated open along the connecting hinge 8, and the reinforcing plate 11 is installed on the door panel 9. This prevents the door panel 9 from being damaged or deformed when the door connecting mechanism 3 applies force to open the door panel 9.

[0025] Please see Figures 1-6 The door opening and closing connection mechanism 3 includes a first reverse joint connector 13, a hinge shaft 15, and a second reverse joint connector 16. A hinge seat 12 is fixedly installed on one side of the reinforcing plate 11. The first reverse joint connector 13 is rotatably connected to the hinge seat 12. The end of the first reverse joint connector 13 away from the hinge seat 12 is hinged to the second reverse joint connector 16 through a connecting shaft 24. The end of the second reverse joint connector 16 away from the first reverse joint connector 13 is rotatably connected to the mounting frame 14. A tension spring 23 is provided between the mounting frame 14 and the connecting shaft 24 to make the first reverse joint connector 13 and the second reverse joint connector 16 exhibit a reverse joint.

[0026] When the drive mechanism 4 applies force, the first reverse joint connector 13 and the second reverse joint connector 16 can rotate relative to each other. In this way, the bent first reverse joint connector 13 and the second reverse joint connector 16 can drive the hinge seat 12 and the opening and closing door panel 9 to open. When the opening and closing door panel 9 is closed, the tension springs are respectively connected to the connecting shafts between the mounting bracket and the first and second reverse joint connectors. This tension spring setting can make the first and second reverse joint connectors present a reverse joint state, thereby preventing the user from opening the opening and closing door panel without authorization.

[0027] Please see Figures 1-4The drive mechanism 4 includes a drive motor 17, an optical axis fixing seat 18, a reverse joint lever 19, and a grooved wheel 20. The drive motor 17 is fixedly installed on one side of the mounting frame 14. The output end of the drive motor 17 is fixedly connected to the fan-shaped optical axis fixing seat 18. A limit sensor 22 is provided on the mounting frame 14 and at the position corresponding to the fan-shaped optical axis fixing seat 18. A fixing frame 21 is fixedly installed on the optical axis fixing seat 18 by two sets of bolts. The grooved wheel 20 is rotatably connected to one side of the connecting shaft 24. The reverse joint lever 19, which contacts the outer wall of the grooved wheel 20, is fixedly installed on one side of the fixing frame 21.

[0028] When the door opening and closing mechanism 3 needs to be driven, the fixed bracket 21 and the optical axis fixing seat 18, connected by two sets of locking bolts, are installed more securely. Then, the drive motor 17 can drive the optical axis fixing seat 18 and the anti-joint lever 19 to rotate. This allows the anti-joint lever 19 to contact and drive the grooved wheel 20, thus moving the grooved wheel 20 forward. This causes the first anti-joint connector 13 and the second anti-joint connector 16 to rotate, allowing the door panel 9 to open normally. When the door panel 9 needs to be closed, the drive motor... 17. Reverse rotation causes the reverse joint lever 19 to rotate in the opposite direction. At this time, the gravity of the door panel 9 will reset and close. With this closing method, even when the user's palm is on one side of the door panel 9, it will only bear the gravity of the door panel 9 itself, and will not bear the driving force of the drive motor 17. When the optical axis fixing seat 18 is continuously rotating to open the door panel 9, the limit sensor 22 can receive the position of the fan-shaped optical axis fixing seat 18, thereby turning off the operation of the drive motor 17 and preventing the door panel 9 from being over-opened.

[0029] Please see Figure 1 and Figure 3 A loading frame 10 is fixedly installed on one side of the door frame 7 and outside the opening and closing door panel 9. The loading frame 10 can extend forward when garbage is put in, so as to prevent garbage from accumulating on the door frame 7 and falling directly into the garbage bin.

[0030] In use, the overflow detection sensor 5 first detects the contents of the trash can on one side of the opening and closing mechanism 1, preventing excessive accumulation of trash that could affect the normal closing of the opening and closing mechanism 1. The overflow detection sensor 5 can be set to have a 10-second effective detection duration. The drive mechanism 4 operates via a contact-driven opening and closing connection mechanism 3, ensuring the opening and closing mechanism 1 can open normally. However, when closing, the opening and closing mechanism 1 uses its own gravity to descend and close, preventing injury to the user even if their hand is placed on the opening and closing mechanism 1 due to the drive mechanism 4. The hinged door panel 9 can be rotated open along the connecting hinge 8, and the reinforcing plate 11 is installed on the hinged door panel 9. This prevents damage and deformation of the hinged door panel 9 when the opening and closing door connecting mechanism 3 applies force to open the hinged door panel 9. When the drive mechanism 4 applies force, the first reverse joint connector 13 and the second reverse joint connector 16 can rotate relative to each other. This allows the hinge seat 12 and the hinged door panel 9 to be opened by the bent first reverse joint connector 13 and the second reverse joint connector 16. When the hinged door panel 9 is closed, the tension springs are respectively connected to the mounting bracket and the first reverse joint connector and the second reverse joint connector. The connecting shaft is connected, and this tension spring setting allows the first and second anti-joint connectors to be in an anti-joint state, thus preventing the user from opening the door panel without authorization. When the door opening and closing connecting mechanism 3 needs to be driven, the fixing bracket 21 and the optical shaft fixing seat 18 connected by two sets of locking bolts are more securely installed. Then, the drive motor 17 can drive the optical shaft fixing seat 18 and the anti-joint lever 19 to rotate. This allows the anti-joint lever 19 to contact and drive the grooved wheel 20, thus driving the grooved wheel 20 forward. This causes the first and second anti-joint connectors 13 and 16 to rotate, making... When the door panel 9 is open normally, the drive motor 17 rotates in reverse when the door panel 9 needs to be closed. This causes the reverse joint lever 19 to rotate in reverse, and the door panel 9 will close due to its own weight. In this closing method, even when the user's palm is on one side of the door panel 9, it will only bear the weight of the door panel 9 itself and will not bear the driving force of the drive motor 17. When the optical axis fixing seat 18 is continuously rotating to open the door panel 9, the limit sensor 22 can detect the position of the fan-shaped optical axis fixing seat 18, thereby turning off the operation of the drive motor 17 and preventing the door panel 9 from being over-opened.
