Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage collection equipment, in particular to a single-rod open-top garbage can with an externally-mounted slow-down device. Background Art
[0002] The garbage can cover is used to prevent garbage from overflowing, keep the environment clean, and prevent the spread of odors and diseases. The garbage cans on the market mainly consist of a barrel body, a barrel cover and other connecting parts. After throwing garbage, allowing the barrel cover to close naturally will cause the barrel cover to drop rapidly, squeezing out a large amount of accumulated odors or bacteria and viruses in the barrel, which may contaminate the person throwing the garbage. In addition, due to the large impact force between the barrel cover and the barrel body, the barrel cover may be deformed or misaligned, affecting its service life, and the noise generated by the collision will also affect the surrounding environment.
[0003] There are mainly two ways to open the garbage can cover: manually lifting the cover and stepping on the top cover with the foot. In the currently common manually lifted garbage cans on the market, the user needs to directly touch the barrel cover during use, which is not hygienic. The pedal-operated garbage cans generally adopt a structure with two side push rods on the top cover. This structure has problems such as the two side push rods being too long and prone to bending and deformation, affecting the service life; the positions of the two side push rods are too far forward, restricting the opening amplitude and affecting the disposal of large garbage; the lifting movement of the two side push rods interferes with the installation of the garbage bag in the garbage can, resulting in the garbage bag being easily detached. In addition, when in use, the barrel cover may flip backward arbitrarily. Summary of the Utility Model

[0018] The drawings in the present utility model are all schematic diagrams, and their sizes do not represent actual sizes;
[0019] The following will be described in detail with reference to the embodiments of the present utility model with reference to the drawings. Detailed Embodiment
[0020] The present utility model will be further described below in conjunction with the drawings and embodiments:
[0021] As Figures 1 to 4As shown in the figure, a single-rod open-top trash can with an external slow-down device includes: a trash can main body 1, a lid 2, a lid connection rotating shaft 3, and a slow-down device 4; the upper barrel shoulder of the trash can main body 1 is adapted to the shape of the lid 2, a box body ear plate is provided at the upper edge of the trash can main body 1, a lid ear plate is provided at the edge of the lid 2, and the lid connection rotating shaft 3 passes through the box body ear plate and the lid ear plate to connect the trash can main body 1 and the lid 2. The slow-down device 4 is arranged on the trash can main body 1 and the lid 2 to prevent the lid 2 from descending too fast. When in use, the lid 2 rotates around the lid connection rotating shaft 3 to realize the opening and closing of the trash can lid body.
[0022] The slow-down device 4 includes: a lid fixing piece 40, a connecting piece 41, a slow-down rod 42, a slow-down device housing 43, a synchronous plate 44, a driving piece 45, a one-way valve 46, a first pipeline 47, a second pipeline 48, and a flow rate controller 49; the slow-down device housing 43 is fixedly installed on the back of the trash can main body 1, the driving piece 45 is fixedly installed inside the slow-down device housing 43, a partition plate is provided inside the slow-down device housing 43, the driving piece 45 is placed on the partition plate, the piston rod of the driving piece 45 is fixedly connected to the synchronous plate 44, the synchronous plate 44 is fixedly connected to the lower end of the slow-down rod 42, so that the piston rod of the driving piece 45 and the slow-down rod 42 are parallel in the same direction. The upper end of the slow-down rod 42 is hinged to the lower end of the connecting piece 41, the rod body of the connecting piece 41 is S-shaped, the upper end of the connecting piece 41 is hinged to the lower end of the lid fixing piece 40, the lid fixing piece 40 is fixedly installed at one end of the lid 2 close to the rotating shaft. The upper interface of the driving piece 45, the upper interface of the one-way valve 46 and the upper end of the first pipeline 47 are connected through a tee pipeline, the lower end of the first pipeline 47 is connected to the flow rate controller 49, the lower interface of the driving piece 45, the lower interface of the one-way valve 46 and the lower end of the second pipeline 48 are connected through a tee pipeline, the upper end of the second pipeline 48 is connected to the flow rate controller 49, and the flow rate controller 49 is fixedly installed on the slow-down device housing 43.
[0023] The driving piece 45 can be a power element such as an oil cylinder or a cylinder that can perform telescoping.
[0024] When the bucket cover 2 is opened, the bucket cover fixing piece 40 is driven by the bucket cover 2 to rotate outward around the cover body connecting rotating shaft 3 together, so that the connecting piece 41 presses the buffer rod 42 downward under force. The buffer rod 42 drives the synchronous plate 44 to move downward, and the synchronous plate 44 drives the piston rod of the driving member 45 to extend. The fluid in the driving member 45 flows out from the lower interface, and most of it returns to the driving member 45 from the upper interface through the one-way valve 46, and a small part returns to the driving member 45 through the second pipeline 48, the flow rate controller 49, and the first pipeline 47 in sequence; when the bucket cover 2 falls naturally, the bucket cover fixing piece 40 is driven by the bucket cover 2 to rotate inward around the cover body connecting rotating shaft 3 together, so that the connecting piece 41 pulls the buffer rod 42 upward under force. The buffer rod 42 drives the synchronous plate 44 to move upward, and the synchronous plate 44 drives the piston rod of the driving member 45 to retract. The fluid in the driving member 45 flows out from the upper interface. Because it cannot move downward through the one-way valve 46, most of the fluid returns to the driving member 45 from the lower interface through the first pipeline 47, the flow rate controller 49, and the second pipeline 48 in sequence. By controlling the flow rate change of the fluid substance in the pipe through the flow rate controller 49, the telescopic speed of the piston rod of the driving member 45 is controlled, and then the rising speed of the buffer rod 42 is controlled, so that the falling process of the bucket cover 2 is buffered and the whole process is more uniform and smooth.
[0025] A compression spring 420 is sleeved on the bottom of the buffer rod 42, and a pressing plate 421 is fixedly sleeved on the buffer rod 42. The bottom of the pressing plate 421 abuts against the top of the compression spring 420, and the bottom of the compression spring 420 abuts against the partition plate of the buffer device housing 43. When the bucket cover 2 is opened, the pressing plate 421 compresses the compression spring 420 to generate resistance, and the resistance reaches the maximum value when it is opened to 90 degrees, so that the bucket cover 2 will not flip backward arbitrarily, increasing the probability of automatic closing after the bucket cover 2 is opened; combined with the buffer force generated by the buffer device 4, the bucket cover 2 can maintain a fixed state when it is turned to more than 90 degrees and less than 100 degrees, leaving enough time for the garbage thrower to complete when throwing a large amount of garbage. Subsequently, with a little external force, the bucket cover 2 can close itself; when the bucket cover 2 is further flipped outward with greater force, the connecting piece 41 starts to move upward in the reverse direction as the bucket cover fixing piece 40 rotates, and the bucket cover 2 can be flipped to 270 degrees, so that the bucket cover 2 is close to the trash can main body 1, without affecting the cleaning and wiping of the inside and outside of the trash can by the cleaning staff, and without affecting the garbage transfer vehicle to hook the bucket and dump and collect garbage.
[0026] It also includes: a single-rod cover opening device 5, which includes: a rotating rod 50, a fixed pipe 51, a fixed square steel 52, a rotating seat 53, a top rod 54, and a protrusion 55. The bottom of the trash can body 1 is fixedly provided with a fixed pipe 51 and a fixed square steel 52. The rotating rod 50 is rotatably connected with the fixed pipe 51 and the fixed square steel 52. The rotating rod 50 is L-shaped, and the end point of the long side of the rotating rod 50 is fixedly connected with the rotating seat 53. The rotating seat 53 is rotatably connected with the lower end of the top rod 54. The top of the top rod 54 passes through the barrel shoulder of the trash can body 1 and is fixedly connected with a protrusion 55. The protrusion 55 abuts against the bottom surface of the barrel cover 2 near the cover body connecting shaft 3. The top rod 54 passes through the housing 43 of the slow-down device. Because the top rod 54 is long, it is generally formed by fixing two upper and lower rods. The connection point of the two rods is located in the middle section of the top rod 54. A rod sleeve is provided on the outer surface of the connection point to ensure that the top rod 54 can move vertically upward.
[0027] A foot pedal 56 is provided above the short side of the rotating rod 50, and the foot pedal 56 is rotatably connected to the trash can body 1. When the foot pedal 56 is stepped on, the short side of the rotating rod 50 is downward, driving the rotating rod 50 to rotate, driving the rotating seat 53 to rotate upward around the long side of the rotating rod 50, driving the push rod 54 to push upward, and causing the protrusion 55 to push open the bucket cover 2.
[0028] The bottom of the back of the trash can body 1 is provided with moving wheels 6, which facilitates the movement of the trash can.
[0029] The barrel cover 2 is provided with a handle.
[0030] In summary, this device maintains the original size and appearance of the trash can, and by adding a set of descending devices 4 to the trash can body 1 and the lid 2, the gravity-falling closing process of the lid 2 can be effectively controlled, so that the closing speed of the lid 2 can be adjusted according to actual needs; by adding a single-rod opening device 5, the principle of mechanical lever is adopted, and the opening of the lid 2 is controlled by a single push rod 54 on the back side of the trash can body 1; by adding a compression spring 420 and a pressure plate 421 in conjunction with the descending device 4, the flipping restriction function of the lid 2 can be realized.
[0031] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
