Technical Field

[0001] The utility model relates to the technical field of garbage storage containers, and particularly relates to a pull rope mechanism for a garbage bin opening door and a garbage bin. Background Art

[0002] Garbage classification generally refers to a series of activities that classify, store, place and transport garbage according to certain regulations or standards, thereby transforming it into a public resource. The purpose of garbage classification is to improve the resource value and economic value of garbage, strive to make the best use of materials, reduce the amount of garbage to be processed and the use of processing equipment, reduce processing costs, and reduce the consumption of land resources. It has social, economic, and ecological benefits. In order to gradually establish people's awareness of garbage sorting and disposal, various forms of garbage sorting and recycling equipment have been set up in residential communities. The garbage inlets of the above-mentioned garbage sorting and recycling equipment are all set forward, and the garbage inlets are equipped with garbage bin doors that can be opened and closed intelligently. That is, when the sensor on the garbage sorting and recycling equipment is triggered or verified, the electric push rod of the garbage bin door automatically opens the garbage bin door of the corresponding type of garbage, and then the garbage to be placed is placed into the garbage bin through the garbage inlet. After the garbage is placed, the garbage bin door is automatically closed.

[0003] The garbage bins currently used in residential areas rarely have a normally open function on their opening doors. Therefore, during the peak hours of garbage disposal in the morning and evening, the electric push rods of the garbage bin opening doors have to repeatedly extend and retract to open / close the garbage bin opening doors, which affects the service life of the electric push rods. Each opening and closing of the garbage bin opening door takes a certain amount of time, and users need to queue up to wait for the garbage bin opening door to open, which reduces the efficiency of garbage disposal and affects the user experience. Summary of the Invention

[0004] The utility model provides a pull rope mechanism for a garbage bin opening door and a garbage bin, which overcomes the above-mentioned deficiencies in the prior art and can effectively solve the problem that the garbage bin opening door of the existing garbage bin has no normally open function. During the peak hours of garbage disposal in the morning and evening, the electric push rod of the garbage bin opening door repeatedly extends and retracts to open / close the garbage bin opening door, which affects the service life of the electric push rod; each time the garbage bin opening door is opened and closed, a certain amount of time is required, and users need to queue up to wait for the garbage bin opening door to open, resulting in low garbage disposal efficiency and affecting the user experience.

[0005] One of the technical solutions of the present utility model is achieved through the following measures: a pull rope mechanism for a garbage bin opening door, comprising a base plate and a pull rope, wherein a spring fixing column and a pull rope fixing column are fixedly installed on the upper right rear side and the upper left front side of the base plate respectively; a tension spring is sleeved on the outer side of the spring fixing column; a pull rope hole is provided on the right front side of the base plate, which passes through the upper and lower parts, and a pull rope is passed through the pull rope hole, and one end of the pull rope located above the base plate passes through the inner side of the hook ring at the front end of the tension spring and is fixedly installed on the pull rope fixing column, and the other end of the pull rope is fixedly installed with a door opening part, which can fix the garbage bin opening door and keep the garbage bin opening door in a normally open state.

[0006] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:

[0007] A fixed pillar can be fixedly installed on the upper side of the bottom plate at the rear position of the corresponding pull rope hole, and a steering rod inclined to the left front and right rear can be fixedly installed on the front side of the middle part of the fixed pillar, and the pull rope can pass around the upper side of the right rear part of the steering rod.

[0008] A limit baffle can be fixedly installed on the upper end of the fixed support to prevent the pull rope from falling off.

[0009] The drawstring hole may be provided with a hollow connector sleeved on the outside of the drawstring.

[0010] A hollow anti-wear sleeve can be fixedly installed in the above-mentioned pull rope hole, and the anti-wear sleeve can be sleeved on the outside of the pull rope.

[0011] A wear-resistant portion may be provided between the hook at the front end of the tension spring and the pull rope, the rear portion of the wear-resistant portion may be hooked with the hook at the front end of the tension spring, and the pull rope may pass through the inner side of the front portion of the wear-resistant portion.

[0012] The door opening portion may be a pull ring.

[0013] The end of the pull rope located on the upper side of the bottom plate can be wound into a rope loop through a wire clip, and the rope loop is sleeved on the outer side of the middle part of the pull rope fixing column.

[0014] The upper ends of the spring fixing column and the pull rope fixing column can be provided with anti-slip baffles.

[0015] The second technical solution of the present invention is achieved through the following measures: a garbage bin, comprising a garbage bin body and a pull rope mechanism for a garbage bin opening door.

[0016] The utility model has a reasonable and compact structure, is easy to use and simple to operate. It sets a tension spring so that the pull rope can be retracted into the trash can body under normal use, avoiding affecting the automatic opening / closing of the trash can opening door by the electric push rod; during the peak period of garbage delivery in the morning and evening, after the trash can opening door is opened to a predetermined angle, the door opening part is pulled downward, so that the pull rope can overcome the pre-tightening force of the tension spring and stretch toward the trash can opening door. When the door opening part is stretched to the middle of the front end of the trash can opening door, the door opening part is used to fix the middle of the front end of the trash can opening door, so that the trash can opening door can be kept in a normally open state, thereby avoiding excessive wear of linear actuators such as electric push rods due to repeated opening / closing of the trash can opening door in a short period of time, affecting the service life and increasing the maintenance cost of the trash can. At the same time, it can also enable users to quickly and directly put garbage into the corresponding opening, effectively shortening the user's waiting time, improving the garbage delivery efficiency and enhancing the user experience.

DETAILED DESCRIPTION

[0023] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0024] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0025] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0026] Example 1: As shown in the attached Figures 1 to 5 As shown, the pull rope mechanism for the trash bin opening door includes a base plate 1 and a pull rope 2, and a spring fixing column 3 and a pull rope fixing column 4 are fixedly installed on the upper right rear side and the upper left front side of the base plate 1 respectively; a tension spring 5 is sleeved on the outer side of the spring fixing column 3; a pull rope hole is provided on the right front side of the base plate 1, which passes through the upper and lower parts, and a pull rope 2 is passed through the pull rope hole. The end of the pull rope 2 located above the base plate 1 passes through the inner side of the hook ring 6 at the front end of the tension spring 5 and is fixedly installed on the pull rope fixing column 4. The other end of the pull rope 2 is fixedly installed with a door opening part, which can fix the trash bin opening door 19 and keep the trash bin opening door 19 in a normally open state.

[0027] In the above technical solution, the tension spring 5 is hooked onto the spring fixing column 3 through the hook ring 6 at its rear end, thereby achieving fixed installation between the tension spring 5 and the spring fixing column 3. The end of the pull rope 2 located above the base plate 1 can be directly tied to the pull rope fixing column 4; or a pull rope fixing hole can be opened in the pull rope fixing column 4, and the axis of the pull rope fixing hole is perpendicular to the axis of the pull rope fixing column 4, and the end of the pull rope 2 located above the base plate 1 is fixedly installed in the pull rope hole; or the end of the pull rope 2 located above the base plate 1 can be welded to the pull rope fixing column 4; or the end of the pull rope 2 located above the base plate 1 can be tied into a rope loop, and the rope loop can be put on the outside of the pull rope fixing column 4; or a loop can be welded and fixed to the end of the pull rope 2 located above the base plate 1, and the pull rope 2 can be fixed to the pull rope fixing column 4 through the loop.

[0028] The garbage delivery ports 18 of the classified garbage bins in the prior art are all set forward, and a garbage bin delivery port door 19 is hingedly installed on the garbage bin body 17 corresponding to each garbage delivery port 18, and the opening / closing of the garbage bin delivery port door 19 is controlled by a linear actuator such as an electric push rod, an air cylinder or a liquid cylinder. The automatic opening mechanism of the garbage bin delivery port door 19 is an existing technology in the field of classified garbage bins and will not be repeated here.

[0029] According to the needs, a pull rope mechanism for the trash bin opening door is fixedly installed in the trash bin body 17 corresponding to the position above each trash bin opening door 19. The fixing installation method of the pull rope mechanism for the trash bin opening door can be bonding, welding, riveting or fixing with welding nails and nuts, etc.; a rope threading hole that passes through the inside and outside is provided on the trash bin body 17 corresponding to the position of each rope hole, and the end of the pull rope 2 close to the rope threading hole passes through the pull rope hole and the rope threading hole from top to bottom in turn and is fixed to the middle part of the upper end of the door opening.

[0030] According to needs, the door opening part can be a hook, a hook or a clip, etc. When in use, the door opening part is pulled downward with force, and the tension spring 5 can be extended under the traction of the pull rope 2, so that the pull rope 2 can be pulled out and extended downward along the pull rope hole until the door opening part can be just aligned with the front middle part of the trash can opening door 19 after it is flipped open. At this time, the hook or hook is hooked on the front middle part of the trash can opening door 19 (or the clip is clamped on the front middle part of the trash can opening door 19), so that the front middle part of the trash can opening door 19 can be fixed, so that the trash can opening door 19 remains in a normally open state, so that the user can directly put the garbage into the corresponding opening without waiting for the trash can opening door 19 to open, saving garbage delivery time and improving the efficiency of garbage delivery operations.

[0031] During use, during normal periods, the door opening is in a free state and is not subject to downward external force. The tension spring 5 is in a contracted state or a pre-stretched state. The tension spring 5 pulls the pull rope 2 through the hook ring 6 at its front end, so that the pull rope 2 is completely contracted on the upper side of the base plate 1, thereby not affecting the automatic opening and closing of the trash bin opening door 19 by linear actuators such as electric push rods.

[0032] During the peak period of garbage delivery, when the sensor on the garbage bin is triggered or verified, the electric push rod and other linear actuators will automatically open the garbage bin opening door 19 of the corresponding type of garbage; when the garbage bin opening door 19 is opened to a predetermined angle, the door opening part is pulled downward with force, and the pull rope 2 stretches the tension spring 5 forward through the hook ring 6 at the front end of the tension spring 5; as the door opening part moves downward, the pull rope 2 is stretched downward along the pull rope hole until the door opening part is just aligned with the middle of the front end of the garbage bin opening door 19. At this time, the door opening part is fixed to the middle of the front end of the garbage bin opening door 19, which can prevent the front end of the garbage bin opening door 19 from flipping down and resetting, so that the garbage bin opening door 19 can remain open, so that the garbage bin that does not have the normally open function can temporarily have the normally open function, thereby avoiding the electric push rod and other linear actuators from repeatedly opening / closing the garbage bin opening door 19, so as to reduce the wear of the electric push rod and other linear actuators and extend the service life of the electric push rod and other linear actuators. When the trash bin opening door 19 is normally open, users can directly put the garbage into the corresponding opening without waiting in line for the trash bin opening door 19 to open, which can greatly improve the garbage delivery efficiency and enhance the user experience.

[0033] When the peak period of garbage delivery is over, the door opening part is removed from the middle part of the front end of the garbage bin delivery door 19, and the door opening part is loosened. The pull rope 2 and the door opening part automatically retract under the restoring force of the tension spring 5, so that the pull rope 2 retracts upward to the upper side position of the bottom plate 1. At the same time, the garbage bin delivery door automatically returns to the closed state under the action of the electric push rod.

[0034] The utility model has a reasonable and compact structure, is easy to use and simple to operate. By setting a tension spring 5, the pull rope 2 can be retracted into the garbage bin body 17 under normal use, avoiding affecting the automatic opening / closing of the garbage bin opening door 19 by the electric push rod; during the peak period of garbage delivery in the morning and evening, after the garbage bin opening door 19 is opened to a predetermined angle, the door opening portion is pulled downward, so that the pull rope 2 overcomes the pre-tightening force of the tension spring 5 and stretches toward the garbage bin opening door 19. When the door opening portion is just aligned with the middle of the front end of the garbage bin opening door 19, the door opening portion is used to fix the front end of the garbage bin opening door 19, so that the garbage bin opening door 19 can be kept in a normally open state, thereby avoiding the electric push rod from repeatedly opening and closing the garbage bin opening door 19 in a short period of time, causing excessive wear, affecting the service life, and increasing the maintenance cost of the garbage bin. At the same time, it can also enable users to quickly and directly put garbage into the corresponding opening, shortening the user's waiting time, greatly improving the garbage delivery efficiency, and enhancing the user experience.

[0035] The above-mentioned pull rope mechanism for the trash bin opening door can be further optimized and / or improved according to actual needs:

[0036] Example 2: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, a fixed pillar 7 is fixedly installed on the upper side of the base plate 1 at the rear position corresponding to the pull rope hole, and a steering rod 8 is fixedly installed on the front side of the middle part of the fixed pillar 7, which is inclined to the left front and right rear. The pull rope 2 passes around the upper right rear side of the steering rod 8.

[0037] With this arrangement, the pull rope 2 passes around the upper side of the steering rod 8 and then enters the pull rope hole. The steering rod 8 can guide the pull rope 2 to turn, and separate the pull rope 2 from the inner wall of the rear side of the pull rope hole by a certain distance, effectively reducing the friction between the pull rope 2 and the inner wall of the rear side of the pull rope hole, thereby reducing the wear of the pull rope 2 and the pull rope hole, and preventing the pull rope 2 from wearing, cutting and deforming the pull rope hole, thereby preventing the need to replace the base plate 1, and effectively extending the service life of both through the steering rod 8.

[0038] If desired, the right front side of the steering rod 8 can be aligned with the rear of the drawstring hole, which is more conducive to isolating the drawstring 2 from the inner wall of the rear side of the drawstring hole by a certain distance. To reduce friction between the tension spring 5 and the base plate 1, the hook 6 at the rear end of the tension spring 5 can be hooked onto the outer middle part of the spring fixing column 3. The upper end of the drawstring 2 is fixedly mounted in the middle of the drawstring fixing column 4. The drawstring 2 stretches the tension spring 5 by a certain length, applying a spring preload force to the tension spring 5. At this time, the upper end of the door opening is exactly against the lower side of the base plate 1, and the drawstring 2 is in a taut state, thereby ensuring that the drawstring 2 and the tension spring 5 are separated by a certain distance from the upper side of the base plate 1 and remain suspended.

[0039] In the above technical solution, the steering rod 8 can also be realized by a fixed pulley with a wider groove width. In order to prevent the pull rope 2 from falling off the fixed pulley, a baffle can be set on the fixed pulley at the upper end position of the corresponding slide groove.

[0040] Example 3: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, a limit baffle 9 is fixedly installed on the upper end of the fixed support 7 to prevent the pull rope 2 from falling off.

[0041] In the above technical solution, the outer dimensions of the limit baffle 9 are much larger than those of the fixed pillar 7; after the door opening part is removed from the middle of the front end of the trash bin opening door 19 and released, the pull rope 2 quickly retracts with the door opening part under the restoring force of the tension spring 5. The pull rope 2 is easy to rebound during the retraction process, and there is a risk that the pull rope 2 will fall off after passing over the upper end of the fixed pillar 7. The setting of the limit baffle 9 can solve the above problem well.

[0042] Example 4: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, a hollow connector 10 is provided in the drawstring hole and sleeved on the outside of the drawstring 2.

[0043] With this arrangement, after a through-hole for passing a rope is formed on the trash bin body 17 corresponding to the position above the opening, the hollow connector 10 can be used to securely connect the bottom plate 1 to the trash bin body 17 via the rope hole and the rope hole, so that the trash bin opening door can be fixedly installed in the trash bin body 17 using the rope mechanism. At the same time, the hollow inner cavity of the hollow connector 10 also allows the rope 2 to pass smoothly through and move up and down within the hollow inner cavity.

[0044] According to the requirements, the hollow connector 10 can be a bolt with an axial hollow channel and a nut fixedly mounted on the bolt. When in use, the bottom plate 1 and the trash box body 17 are fixedly mounted together by the above-mentioned bolt and nut; the hollow connector 10 can also be a hollow rivet or a rivet nut. When in use, the bottom plate 1 is fixedly mounted in the trash box body 17 by riveting. After the riveting is completed, the cavity in the hollow rivet or rivet nut can be used to pass the pull rope 2. In this embodiment, the hollow connector can be a countersunk or flat head rivet nut, such as Figure 4 shown.

[0045] Example 5: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, a hollow anti-wear sleeve 11 is fixedly installed in the pull rope hole, and the anti-wear sleeve 11 is sleeved on the outside of the pull rope 2.

[0046] By such an arrangement, the wear of the drawstring 2 on the rear inner wall of the drawstring hole can be effectively reduced, thereby reducing the replacement and maintenance costs of parts.

[0047] During use, even if the anti-wear sleeve 11 is worn, the anti-wear sleeve 11 can be simply and quickly replaced during the maintenance and inspection process of the garbage bin.

[0048] According to requirements, the anti-wear sleeve 11 can be a wear-resistant plastic sleeve, a copper sleeve, a graphite sleeve, a self-lubricating sleeve or a steel sleeve with an anti-wear inner wall; when a hollow connector 10 is used to fix the base plate 1 and the garbage box body 17, the anti-wear sleeve 11 can be fixedly installed in the hollow inner cavity of the hollow connector 10 by interference connection, bonding, welding, riveting or integral molding; in this embodiment, the anti-wear sleeve 11 can be a T-shaped anti-wear sleeve.

[0049] Example 6: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, a wear-resistant portion 12 is provided between the hook ring 6 at the front end of the tension spring 5 and the pull rope 2. The rear portion of the wear-resistant portion 12 is hooked with the hook ring 6 at the front end of the tension spring 5, and the pull rope 2 passes through the inner side of the front portion of the wear-resistant portion 12.

[0050] This arrangement can prevent the pull rope 2 from wearing the hook 6 at the front end of the tension spring 5 and the hook 6 at the front end of the tension spring 5 from wearing the pull rope 2, thereby extending the service life of the tension spring 5 and the pull rope 2 and reducing the maintenance cost of components.

[0051] According to requirements, the wear-resistant part 12 can be a wear-resistant ring, an 8-shaped ring, a hook, a hook, a key chain, a fish-mouth buckle, a rotating hook, a rotating buckle, a shackle, a U-shaped ring, a C-shaped ring or a quick draw in the prior art; it can also be a single pulley, the U-shaped ring on the single pulley is hooked together with the hook ring 6 at the front end of the tension spring 5, and the pull rope 2 passes around the pulley on the single pulley from back to front.

[0052] Example 7: As an optimization of the above embodiment, as shown in the attached Figures 2 to 5 As shown, the door opening portion is a pull ring 13.

[0053] In the above technical solution, the garbage bin opening door 19 includes a cover body 1901 and a limiting ring 1902. The cover body 1901 is hinged on the garbage bin body 17 at the rear side of the garbage opening 18. The cover body 1901 can just block the garbage opening 18. A limiting ring 1902 is provided in the garbage opening 18, the upper end of which is fixedly installed at a corresponding position on the lower side of the cover body 1901. The shape of the limiting ring 1902 is complementary to the shape of the garbage opening 18. The limiting ring 1902 can be inserted into the garbage opening 18 to prevent the cover body 1901 from moving. The lower front part of the limiting ring 1902 is provided with a notch 20 that opens downward and passes through from front to back.

[0054] During use, when the front end of the trash bin opening door 19 rotates backward into place under the action of the electric push rod, pull the pull ring 13 down so that the pull ring 13 is aligned with the notch 20 in the middle of the front end of the limit ring 1902, and continue to pull the pull ring 13 down. After the pull rope 2 above the pull ring 13 is aligned with the notch 20, the pull rope 2 is inserted into the notch 20, and the pull ring 13 is released. The upper end of the pull ring 13 is just against the inner side wall of the middle of the front end of the limit ring 1902, and the front middle of the trash bin opening door 19 can be hooked by the pull ring 13 and the pull rope 2, preventing the trash bin opening door 19 from rotating forward and resetting, so that the trash bin opening door 19 can remain in a normally open state, which is convenient for directly throwing garbage into the trash bin without waiting for the trash bin opening door 19 to open, saving users' garbage delivery time and improving the efficiency of garbage delivery operations.

[0055] According to requirements, the pull ring 13 and the lower end of the pull rope 2 can be connected by a vertical double-hole locker in the prior art. The vertical double-hole locker includes a hexagonal screw and a hollow cylindrical connecting rod. The cylindrical connecting rod is provided with two through holes at intervals above and below, and the upper through hole is connected with a hexagonal screw through a thread; when in use, after inserting the lower end of the pull rope 2 into the inner side of the upper part of the cylindrical connecting rod, the lower end of the pull rope 2 is fixed by the hexagonal screw, and the pull ring 13 is installed in the vertical hole at the lower part; when the pull rope 2 is stuck in the notch 20, the upper end of the cylindrical connecting rod is just against the inner side wall of the middle part of the front end of the limit ring 1902 to fix the cover body 1901, so that the garbage bin opening door 19 remains in a normally open state.

[0056] Example 8: As an optimization of the above embodiment, as shown in the attached Figures 1 to 2 As shown, the end of the pull rope 2 located on the upper side of the base plate 1 can be wound into a rope loop 15 through a wire clip 14, and the rope loop 15 is sleeved on the outer side of the middle part of the pull rope fixing column 4.

[0057] By such arrangement, the bent portion of the end of the draw rope 2 can be fastened with the wire clip 14 to form a rope loop 15, which makes it easier to disassemble and replace the draw rope 2, thereby improving the efficiency of the garbage bin maintenance operation.

[0058] According to the requirements, the clamping member 14 can be a wire rope locker, a wire rope buckle, a wire rope clamp, a wire rope aluminum sleeve, a wire rope lock buckle or a brake wire clamp etc. in the prior art.

[0059] Example 9: As an optimization of the above embodiment, as shown in the attached Figures 1 to 4 As shown, an anti-slip baffle 16 is provided at the upper end of the spring fixing column 3 and the pull rope fixing column 4.

[0060] This arrangement can effectively prevent the hook 6 at the rear end of the tension spring 5 from falling off the spring fixing column 3 , and simultaneously prevent the pull rope 2 from falling off the pull rope fixing column 4 .

[0061] According to requirements, each anti-slip baffle 16 can be fixedly installed on the corresponding spring fixing column 3 and the pull rope fixing column 4 by welding, bonding, riveting, threaded connection or threaded fasteners; the anti-slip baffle can be realized by a flat plate limiter, a limit rope loop, a limit nut or an anti-slip cap with an opening downward. In this embodiment, the limit baffle can be a rubber anti-slip cap.

[0062] Example 10: As shown in the attached Figures 3 to 5 As shown, a trash can includes a trash can body 17 and a pull rope mechanism for a trash can opening door.

[0063] In the above technical solution, it is possible to Figure 3 Taking the classified trash bin shown in the figure as an example, the specific implementation method can be as follows:

[0064] A sensing device 21 is provided on the trash box body 17 at a position above the front of each trash delivery port 18. The sensing device 21 can detect whether a user has delivered trash in front of the corresponding trash delivery port 18 of the trash box.

[0065] A rope threading hole that passes through the inside and outside is provided on the garbage bin body 17 corresponding to the position behind each sensing device 21; a rope pulling mechanism for the garbage bin opening door is provided in the garbage bin body 17 corresponding to the position above each garbage opening 18. After aligning the rope pulling hole on the bottom plate 1 with the rope threading hole, the bottom plate 1 and the garbage bin body 17 are fixed together through the hollow connecting piece 10, and the anti-wear sleeve 11 is fixedly installed in the hollow cavity of the hollow connecting piece 10.

[0066] Put the hook ring 6 at the rear end of the tension spring 5 onto the spring fixing column 3, then put the rope loop 15 at one end of the pull rope 2 onto the outside of the middle part of the pull rope fixing column 4, and pass the other end through the inner side of the wear-resistant part 12, the upper side of the front of the steering rod 8 and the inner side of the wear-resistant sleeve 11 in turn, and then fix it together with the upper part of the pull ring 13. Finally, hook the wear-resistant part 12 and the hook ring 6 at the front end of the tension spring 5 together; through the spring preload force of the tension spring 5, the upper end of the pull ring 13 is offset from the garbage bin 17 above the corresponding garbage inlet 18, and at the same time, the pull rope 2 and the tension spring 5 are suspended above the base plate 1.

[0067] During use, during the normal period of garbage delivery, under the action of the spring preload of the tension spring 5, the upper end of the pull ring 13 abuts against the garbage bin body 17, so the pull ring 13 will not affect the normal opening and closing of the garbage bin door 19.

[0068] During the peak period of garbage delivery, after the garbage bin opening door 19 is opened to a predetermined angle, the pull ring 13 is pulled downward. After the pull rope 2 above the pull ring 13 is aligned with the notch 20 on the garbage bin opening door 19, the pull rope 2 is inserted into the notch 20 and the pull ring 13 is released. Under the action of the restoring force of the tension spring 5, the upper end of the pull ring 13 can just bear against the inner side wall of the lower front end of the garbage bin opening door 19, preventing the garbage bin opening door 19 from closing forward, so that the garbage bin opening door 19 remains in a normally open state, which is convenient for users to deliver garbage quickly and directly, and avoids queuing for the garbage bin opening door 19 to open. It can effectively increase the garbage delivery rate, shorten the waiting time, and enhance the user experience. At the same time, it can also reduce the number of telescopic actions of the electric push rod, reduce wear and tear, and extend its service life.

[0069] After the peak period of garbage delivery, the pull ring 13 is pulled forward to remove the drawstring 2 from the notch 20. The pull ring 13 is then released. The drawstring 2, under the spring restoring force of the tension spring 5, moves upward with the pull ring 13 until the upper end of the pull ring 13 contacts the corresponding position of the garbage bin body 17. At this point, the drawstring 2 returns to its original state and is completely retracted above the base plate 1. The garbage bin opening door 19 is then reset by a linear actuator such as an electric push rod, resealing the garbage opening 18.

[0070] The above technical features respectively constitute the various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
