[0018] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This patent provides a technical solution: a linkage double-opening waste bin mechanism, including a cabinet body 1 and a connecting rod 5. The left side of the cabinet body 1 has rectangular openings on both the top and bottom sides. The bottom of the rectangular openings is hinged to a cabinet door 2. A handle 4 is fixedly installed on the upper left side of the cabinet door 2. A base plate 7 is fixedly installed on the bottom right side of the cabinet door 2. The top of the base plate 7 has an installation groove, and a waste bin 3 is fixedly installed in the installation groove. The upper and lower ends of the connecting rod 5 are respectively hinged to the front right side of the two base plates 7. The inner bottom wall of the cabinet 1 is provided with a groove, and one end of the telescopic rod 6 is hinged in the groove. The other end of the telescopic rod 6 is hinged to the lower base plate 7. A shaft 8 is fixedly installed on the front right side of the base plate 7, and relative rotating parts 9 are fixedly installed at both the upper and lower ends of the connecting rod 5. The relative rotating parts 9 are rotatably connected to the shaft 8.
[0020] Traditional catering establishments typically have waste trucks with waste bins, usually two bins, for collecting dry and wet food waste separately. However, the two bins need to be opened separately and cannot be opened and closed simultaneously, making them impractical. Furthermore, the tops of most waste bins are exposed, allowing unpleasant odors to easily escape.
[0021] This solution involves hinged two cabinet doors on the left side of the cabinet body, with a base plate installed on the right side of each door. A waste bin is fixedly mounted on the base plate, and the two base plates are hinged together by a connecting rod. When the waste bin needs to be used, simply pull one cabinet door, and the waste bin connected to that door will flip to the outside of the cabinet body. Through the linkage effect of the connecting rod and the telescopic rod, the other waste bin can also flip to the outside of the cabinet body, realizing the linkage opening or closing and achieving the function of single-point operation of simultaneous opening and closing of two doors.
[0022] Cabinet 1: Made of stainless steel, with an overall height of 1200mm, width of 500mm, and depth of 450mm. The rectangular openings on the top and bottom sides of the left side are both 550mm high and 480mm wide. The groove on the right side of the inner bottom wall is 100mm deep and 80mm wide.
[0023] Cabinet door 2: Made of stainless steel, 540mm high, 470mm wide, and 20mm thick. It is hinged to the bottom of the rectangular opening of cabinet body 1. The handle 4, which is fixedly installed on the upper side of the left side, is made of plastic and is 120mm long, 30mm wide, and 20mm thick.
[0024] Waste bin 3: Made of plastic, with a height of 400mm, an upper diameter of 300mm, and a lower diameter of 250mm. It is fixedly installed in the mounting groove of the base plate 7.
[0025] Base plate 7: made of stainless steel, 480mm long, 460mm wide, and 15mm thick. The shaft 8 fixedly installed on the front right side is also made of stainless steel. The lower shaft 8 is 200mm long, the upper shaft 8 is 150mm long, and both are 25mm in diameter.
[0026] Connecting rod 5: made of stainless steel, 500mm in length and 30mm in diameter. Among the relatively rotating parts 9 fixed at both ends, the mounting ring 10 is made of stainless steel, with an inner diameter of 35mm, an outer diameter of 45mm, and a height of 20mm; bearing 11 is a deep groove ball bearing, model 6005; fixing ring 17 is made of stainless steel, with an inner diameter of 25mm, an outer diameter of 40mm, and a thickness of 10mm.
[0027] Telescopic rod 6: Buffer air rod, model QD, stroke 300mm, cylinder diameter 25mm, rod diameter 18mm, one end is hinged to the cabinet body 1 groove, and the other end is hinged to the lower bottom plate 7.
[0028] Specifically, telescopic rod 6 is a buffer gas rod.
[0029] The buffer gas spring provides damping during the closing of cabinet door 2, reducing the impact force and improving safety and quietness. Specifically, the relative rotating component 9 includes a mounting ring 10, a bearing 11, and a retaining ring 17. The outer wall of the mounting ring 10 is fixedly mounted on the end of the connecting rod 5. The outer wall of the outer ring of the bearing 11 is fixedly mounted on the inner wall of the mounting ring 10. The inner wall of the retaining ring 17 is fixedly mounted on the side wall of the shaft 8. The end of the shaft 8 is threaded with a nut 12 through the inner ring of the bearing 11. The left side of the nut 12 is tightly fitted to the right side of the inner ring of the bearing 11, and the left side of the inner ring of the bearing 11 is tightly fitted to the right side of the retaining ring 17.
[0030] Traditional hinged joints mostly involve inserting a rod into a hole and sliding the rod's side wall against the hole's inner wall to achieve rotation. However, this results in significant friction at the contact surfaces and makes the joint prone to jamming.
[0031] By setting the bearing 11, the relative rotation of the shaft 8 and the mounting ring 10 can be made smooth, avoiding friction and jamming, and the setting of the nut 12 facilitates assembly.
[0032] Specifically, the nut 12 includes an internal threaded ring 13 and a pressure ring 14. The internal threaded ring 13 is screwed to the end of the shaft 8. The left end of the internal threaded ring 13 is tightly fitted to the right side of the pressure ring 14. The left side of the pressure ring 14 is tightly fitted to the right side of the inner ring of the bearing 11. The left side of the pressure ring 14 is integrally formed with teeth 15 in a continuous circumferential shape. The right side of the inner ring of the bearing 11 is provided with a toothed groove 16 in a continuous circumferential shape. The teeth 15 are inserted into the toothed groove 16.
[0033] Nut 12: The internal threaded ring 13 is made of stainless steel with an inner diameter of 25mm and a height of 15mm; the pressure ring 14 is made of stainless steel with a diameter of 40mm and a thickness of 8mm. The number of 12 continuously integrally formed teeth 15 on the left side of the ring is adapted to the tooth groove 16 on the right side of the inner ring of the bearing 11; the rubber pads on the left side of the pressure ring 14 and the right side of the retaining ring 17 are 2mm thick and their diameter matches that of the pressure ring 14 and the retaining ring 17.
[0034] By setting the insert teeth 15 to be inserted into the tooth groove 16, the locking effect of the nut 12 on the inner ring of the bearing 11 can be increased.
[0035] Specifically, rubber pads are provided on the left side of the pressure ring 14 and the right side of the fixing ring 17.
[0036] The rubber pads enhance the securing effect of the pressure ring 14 and the retaining ring 17 on the inner ring of the bearing 11.
[0037] Specifically, the length of the lower shaft 8 is greater than the length of the upper shaft 8.
[0038] The lower shaft 8 is longer than the upper shaft 8, which facilitates the hinge connection between the lower shaft 8 and the top of the telescopic rod 6.
[0039] Working principle: This solution has two cabinet doors hinged to the left side of the cabinet body, and a base plate is installed on the right side of the cabinet doors. A waste bin is fixedly installed on the base plate. The two base plates are hinged to each other by a connecting rod. When the waste bin needs to be used, simply pull one cabinet door, and the waste bin connected to this cabinet door will flip to the outside of the cabinet body. Through the linkage effect of the connecting rod and the telescopic rod, the other waste bin can be flipped to the outside of the cabinet body, realizing the linkage opening or closing, and realizing the function of single-point operation of two doors opening and closing simultaneously.
