Description

Technical Field

[0001] This utility model relates to the field of trash cans, and in particular to a foot-operated trash can with a buffer opening and closing function and easy assembly. Background Technology

[0002] Trash cans typically serve as containers to hold and protect trash cans; existing pedal-operated trash cans (such as Chinese patent CN217995540U, which discloses a foot-operated opening trash can) often have the following defects in their linkage mechanism design:

[0003] On the one hand, existing trash cans usually require a clearance opening on the top of the body for the linkage mechanism. This not only increases the manufacturing cost, but also requires the linkage to pass through the clearance opening during installation, which not only extends the product production cycle, but also easily causes damage to the linkage mechanism.

[0004] On the other hand, its linkage mechanism is complex, which not only increases production costs but also makes it difficult to assemble and use for a long time. This directly reduces the overall stability and protective performance of the trash can, ultimately violating the original design intention of the trash can. Utility Model Content

[0005] The main objective of this invention is to provide a foot-operated trash can with a buffer opening and closing function and easy assembly, thereby solving all or one of the aforementioned problems in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a foot-operated trash can with a buffer opening and closing function and easy assembly, comprising:

[0007] The housing and foot pedal linkage mechanism;

[0008] The container is vertically arranged and includes: a frame, two side panels symmetrically installed on both sides of the frame, a rear baffle installed on the rear surface of the frame, a front door panel hinged to the front surface of the frame, and a lid hinged to the top of the frame.

[0009] The foot pedal linkage mechanism includes: a hinge seat, a first buffer, a pedal, a first link arranged in the width direction of the frame, and a second link arranged in the height direction of the frame;

[0010] The second link is inclined and attached to the side plate of the frame from top to bottom. There is a distance between the lower end of the second link and the bottom of the frame. The upper end of the second link is close to the box cover and the upper end of the second link is connected to a bend that avoids the top of the frame. The top of the bend is hinged to the lower surface of the box cover.

[0011] The first connecting rod is inclined and attached to the side plate below the second connecting rod from bottom to top, and the lower end of the first connecting rod is hinged to the lower end of the second connecting rod. The upper end of the first connecting rod extends through the front surface of the frame to the outside of the box. The pedal is horizontally set on the upper surface of the end of the first connecting rod outside the box. There is a distance between the first connecting rod and the bottom of the frame.

[0012] The hinge seat is vertically positioned on the bottom of the frame below the first link and corresponds to the middle position of the first link. The middle position of the first link is rotatably connected to the hinge seat.

[0013] The first buffer is vertically attached to the side plate above the first link and close to the upper end of the first link. The lower end of the first buffer is hinged to the first link between the frame and the hinge seat, and the upper end of the first buffer is hinged to the inner surface of the frame away from the first link. The first buffer is used to reduce the upward speed of the first link.

[0014] The pedal is used to drive the upper end of the first link to make a vertical downward displacement. The upper end of the first link drives the first link to rotate downward around the hinge seat as the rotation axis through the vertical downward displacement. The first link drives the second link to rise through the downward rotation. The second link drives the box cover to flip upward through the rising.

[0015] As an improved solution, the bending section includes: a horizontal bar and a vertical bar;

[0016] The crossbar is inclined upward from right to left and positioned near the second link, with its lower end connected to the upper end of the second link;

[0017] The vertical rod is set parallel to the second connecting rod and is located near the horizontal rod. The lower end of the vertical rod is connected to the upper end of the horizontal rod, and the upper end of the vertical rod is hinged to the lower surface of the box cover near the rear baffle.

[0018] The length of the crossbar is matched to the thickness of the frame.

[0019] As an improved solution, a second buffer is vertically installed on the top surface of the frame at the position corresponding to the edge of the lid. The second buffer is used to reduce the descent speed of the lid.

[0020] As an improved solution, a clearance opening is provided on the front surface of the frame near the bottom of the frame to avoid the first link. The upper end of the first link extends out of the clearance opening, and the bottom of the clearance opening is flush with the upper surface of the bottom of the frame, while the top of the clearance opening is higher than the top of the hinge seat.

[0021] As an improved solution, the hinged seat includes: a support block and a horizontal pivot.

[0022] The support block is vertically installed on the bottom of the frame below the first link and corresponds to the middle of the first link;

[0023] The upper surface of the support block is provided with a hinge groove that matches the width of the first connecting rod. The horizontal rotating shaft is horizontally and rotatably set in the hinge groove, and the middle part of the first connecting rod is sleeved on the horizontal rotating shaft.

[0024] As an improved solution, two first through holes are respectively opened on both sides of the hinge groove, which horizontally penetrate the wall of the hinge groove;

[0025] A second channel is provided horizontally through the first link at the position of the first through hole in the middle of the first link;

[0026] The horizontal rotating shaft is sequentially inserted into a first through hole, a second channel, and another first through hole. Both ends of the horizontal rotating shaft extend out of the hinge groove, and both ends of the horizontal rotating shaft outside the hinge groove are respectively provided with threads, and bolts are installed at the two threads respectively.

[0027] As an improved solution, a reinforcing rib is provided on the lower surface of the box cover near the rear baffle, arranged along the length of the box cover. A connecting seat is provided on the section of the reinforcing rib near the vertical rod, and a hinge hole corresponding to the vertical rod is opened on the connecting seat at the position corresponding to the vertical rod.

[0028] The upper end of the vertical rod is horizontally oriented towards the hinge hole, and the upper end of the vertical rod is hinged to the hinge hole.

[0029] As an improved solution, the foot pedal linkage mechanism is positioned near the right side plate of the housing.

[0030] As an improved solution, the left side of the front door panel is hinged to one side of the frame;

[0031] The first handle is located on the front surface of the front door panel, near the right side panel, and is positioned away from the pedal.

[0032] The front surface of the front door panel has several horizontally penetrating holes that run along the length of the front door panel.

[0033] As an improved solution, a second handle is provided in the middle of the front surface of the box cover. The second handle is U-shaped.

[0034] The beneficial effects of this utility model are as follows: The foot pedal linkage mechanism of this utility model enables the quick and stable installation of the trash can pedal and linkage. Through the design of the bending part, this utility model eliminates the need for adaptive design of the box body, which facilitates production and assembly and improves the structural stability of the trash can. The design of the foot pedal linkage mechanism attached to the side plate allows this trash can to accommodate larger trash cans, improving space utilization. The design of the hinge seat and buffer not only improves the operational stability of the linkage mechanism and extends its overall service life, but also ensures the structural strength of the can body, further enhancing the stability and protective performance of the trash can.

[0044] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0045] Please see Figures 1-7 The embodiments of this utility model include:

[0046] Example 1: A foot-operated trash can with a buffer opening and closing function and easy assembly, such as... Figures 1-5 As shown, it includes: a housing and a foot pedal linkage mechanism;

[0047] like Figure 1 As shown, the box is vertically arranged and includes: a frame 1, left and right side panels 2 symmetrically installed on the left and right sides of the frame 1, a rear baffle 3 installed on the rear surface of the frame 1, a front door panel 4 hinged to the front surface of the frame 1, and an openable box cover 5 hinged to the top of the frame 1. The rear side of the box cover 5 is hinged to the rear side of the top of the frame 1.

[0048] like Figure 2 As shown, the foot pedal linkage mechanism includes: a hinge seat 6, a first buffer 7, a pedal 8, a first link 9 corresponding to the width direction of the frame 1, and a second link 10 corresponding to the height direction of the frame 1. To reduce the occupancy of internal space, the second link 10 is inclined from top to bottom and attached to the side plate 2 on the right side of the frame 1. There is a distance between the lower end of the second link 10 and the bottom of the frame 1. In order to avoid the frame 1 body when attached, the upper end of the second link 10 is close to the box cover 5 and the upper end of the second link 10 is connected to a bend that avoids the top of the frame 1. The top of the bend is hinged to the lower surface of the box cover 5. This bend is an innovative improvement made in the linkage structure in this application. Specifically, the bend includes: a horizontal bar 11 and a vertical bar 12; as shown Figure 5 As shown, the horizontal bar 11 is inclined upwards from right to left and positioned near the top of the second connecting rod 10, with its lower end connected to the upper end of the second connecting rod 10; the vertical bar 12 is parallel to the second connecting rod 10 and positioned near the top of the horizontal bar 11, with its lower end connected to the upper end of the horizontal bar 11, and its upper end hinged to the lower surface of the cover 5 near the rear baffle 3; to allow for clearance with the frame 1, the length of the horizontal bar 11 matches the thickness of the frame 1; through this bending design, the linkage mechanism in this device can be directly connected to the top cover 5 of the garbage bin without requiring additional openings in the garbage bin, which not only improves the internal space utilization of the garbage bin but also reduces production and installation costs and improves production and installation efficiency; Figure 3 As shown, in a preferred embodiment, a reinforcing rib 16 is provided on the lower surface of the box cover 5 near the rear baffle 3, arranged along the length of the box cover 5. A connecting seat 17 is provided on the section of the reinforcing rib 16 near the vertical rod 12. A hinge hole corresponding to the vertical rod 12 is opened on the connecting seat 17. The upper end of the vertical rod 12 is horizontally oriented towards the hinge hole and is hinged to the hinge hole. This design further improves the service life of the box cover 5, so that the vertical rod 12 will not damage the body of the box cover 5 during long-term opening and closing.

[0049] like Figure 2As shown, the first connecting rod 9 is inclined and attached to the side plate 2 below the second connecting rod 10 from bottom to top, and the lower end of the first connecting rod 9 is hinged to the lower end of the second connecting rod 10. The upper end of the first connecting rod 9 extends through the front surface of the frame 1 to the outside of the box. In order to accommodate the structure of the first connecting rod 9, a clearance opening 14 is provided on the front surface of the frame 1 near the bottom of the frame 1 to avoid the first connecting rod 9. The upper end of the first connecting rod 9 extends through the clearance opening 14, and the bottom of the clearance opening 14 is flush with the bottom upper surface of the frame 1. The top of the clearance opening 14 is higher than the top of the hinge seat 6. The pedal 8 is horizontally set on the upper surface of the end of the first connecting rod 9 outside the box. The height of this clearance opening 14 is the movable height of the pedal 8.

[0050] like Figure 2 As shown, a distance is provided between the first connecting rod 9 and the bottom of the frame 1; the hinge seat 6 is vertically arranged on the bottom of the frame 1 below the first connecting rod 9 and corresponds to the middle position of the first connecting rod 9. The middle position of the first connecting rod 9 is rotatably connected to the hinge seat 6. Through the design of this hinge seat 6, it provides stable support for the first connecting rod 9 and becomes a stable fulcrum when the first connecting rod 9 rotates. Since the hinge seat 6 is installed on the frame 1 body, it has strong stability. Of course, in an optional embodiment, such as... Figure 3 As shown, the hinge seat 6 includes: a support block and a horizontal rotating shaft; the support block is vertically disposed on the bottom of the frame 1 below the first connecting rod 9 and corresponds to the middle position of the first connecting rod 9; a hinge groove 15 matching the width of the first connecting rod 9 is formed on the upper surface of the support block; the horizontal rotating shaft is horizontally and rotatably disposed in the hinge groove 15; the middle part of the first connecting rod 9 is sleeved on the horizontal rotating shaft; in order to realize the hinged sleeve, two first through holes are respectively formed on both sides of the hinge groove 15, which are horizontally penetrating the groove wall of the hinge groove 15; the position of the middle part of the first connecting rod 9 corresponds to the position of the first through hole. A second channel is provided that horizontally penetrates the first connecting rod 9; a horizontal rotating shaft is sequentially inserted into a first through hole, the second channel, and another first through hole, with both ends of the horizontal rotating shaft extending out of the hinge groove 15, and threads are provided at both ends of the horizontal rotating shaft outside the hinge groove 15, with bolts installed at the two threads respectively; the hinge seat 6 has good stability through the above connection; the support block and the frame 1 body are also connected to each other through a fixing screw that vertically penetrates the support block and the bottom of the frame 1, and a bolt that is locked to the bottom of the fixing screw;

[0051] like Figure 4As shown, the first buffer 7 is vertically attached to the right side plate 2 above the first connecting rod 9 and close to the upper end of the first connecting rod 9. The lower end of the first buffer 7 is hinged to the first connecting rod 9 located between the frame 1 and the hinge seat 6, and the upper end of the first buffer 7 is hinged to the inner surface of the frame 1 away from the first connecting rod 9. In practical applications, the first buffer 7 may include, but is not limited to, using a pneumatic rod, a hydraulic rod, or a spring as a buffer component, so that the first connecting rod 9 can be slowly pulled back after the pedal 8 is pressed, ensuring the safety and reliability of the device during use.

[0052] like Figure 5 As shown, a second buffer 13 is vertically installed on the top surface of the frame 1 at the position corresponding to the edge of the cover 5. The second buffer 13 can be a hydraulic buffer or an oil pressure buffer, used to buffer the force when the cover 5 falls, and thus cooperate with the first buffer 7 to achieve the "seamless / silent" closing of the cover 5.

[0053] like Figure 1 As shown, to improve the applicability of this device, the left side of the front door panel 4 is hinged to one side of the frame 1; a first handle 18 is provided on the front surface of the front door panel 4 near the right side panel 2, and the first handle 18 is located away from the pedal 8; several horizontal holes 19 are evenly provided on the front surface of the front door panel 4, which are arranged along the length of the front door panel 4 and are used to achieve ventilation; of course, in this embodiment, the device structure is designed with the operator's dominant hand as the right hand, so the foot pedal linkage mechanism and the first handle 18 are located on the right side panel 2 of this device. When the operator's dominant hand is the left hand, the corresponding foot pedal linkage mechanism and the first handle 18 can also be located on the left side panel 2 of this device.

[0054] like Figure 1 As shown, in order to facilitate the opening of the lid 5, a U-shaped second handle 20 is provided in the middle of the front surface of the lid 5.

[0055] In a preferred embodiment, when using this device, the frame 1 houses a trash can for holding garbage, and the device's housing protects and seals the trash can. When garbage needs to be disposed of in the trash can, the operator steps down on the pedal 8, causing the upper end of the first connecting rod 9 to move vertically downwards. This vertical downward movement causes the first connecting rod 9 to rotate downwards about the hinge seat 6 as its rotation axis. Simultaneously, the downward rotation of the first connecting rod 9 causes its lower end to tilt upwards, which in turn causes the second connecting rod 10 to rise. The rising of the second connecting rod 10 causes the vertical rod 12 at the bend to lift the lid 5. Since the lid 5 is hinged to the frame 1, it flips upwards, opening the lid 5 for garbage disposal. After garbage disposal, the operator removes their foot from the pedal 8, and the lid 5 begins to fall under gravity, causing... The bending section descends, causing the second connecting rod 10 to descend as well. The descent of the second connecting rod 10 causes the first connecting rod 9 to rotate upwards on the hinge seat 6, raising the upper end of the first connecting rod 9 and thus resetting the pedal 8. During this process, the first buffer 7 continuously reduces the upward speed of the first connecting rod 9, thus reducing the initial descent speed of the lid 5. When the lid 5 falls to the upper end of the second buffer 13, the second buffer 13 further reduces the descent speed of the lid 5 in the subsequent descent. During this process, the first buffer 7 continues to reduce the upward speed of the first connecting rod 9. This continuous process causes the lid 5 to close slowly, and the pedal 8 to reset slowly, ensuring the flexible use of the device and guaranteeing the independent safety and reliability of each component during operation, thus contributing to extending the device's service life.

[0056] Example 2: A foot-operated trash can with a buffer opening and closing function and easy assembly, such as... Figure 6 and Figure 7 As shown, unlike Embodiment 1, the foot-operated trash can in this embodiment has two boxes connected side by side and two foot-operated linkage mechanisms respectively set in the two boxes. One foot-operated linkage mechanism is set to the left side plate 2 of the left box and the other foot-operated linkage mechanism is set to the right side plate 2 of the right box. Of course, it can be imagined that the number of boxes and the foot-operated linkage mechanisms are not limited here. There can be more boxes, and the foot-operated linkage mechanism is a matching mechanism that corresponds to each box. Moreover, the foot-operated trash can in this embodiment can realize the placement of multiple garbage sorting bins. Its operating principle is the same as that of the foot-operated trash can in Embodiment 1.

[0057] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
