Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and in particular to a foldable sanitation waste collection bag support. Background Technology

[0002] Garbage collection bags are flexible containers used to hold and temporarily store various types of garbage. They are usually made of plastic, biodegradable materials, etc., and have the basic characteristics of being portable, airtight, and tear-resistant. They are the core tools for sanitation operations and garbage disposal in households or public places.

[0003] An investigation revealed that a Chinese utility model patent, publication number CN212149417U, discloses a fruit and vegetable bag holder. This patent includes a bag holder body with a material discharge port. Bag opening supports are rotatably mounted on both sides of the material discharge port. The bag holder body also includes a drive unit for synchronously and counter-oscillating the bag opening supports. This application utilizes a bag holder positioned at the outlet of a fruit and vegetable sorting machine. The bag opening supports on the bag holder open and close the bag openings, facilitating fruit and vegetable bagging. The process of filling the fruit and vegetable bags eliminates the need for manual opening of the bag openings, offering high convenience for fruit and vegetable bagging.

[0004] The aforementioned patent does not have a multi-level folding angle adjustment structure for users, making it impossible to flexibly adjust the opening angle of the support frame according to the collection scenario. This limits its adaptability. Furthermore, when dealing with thin or thick garbage collection bags, it is prone to problems such as insecure clamping or damage to the bags, reducing collection stability. When it is necessary to move between multiple work points, the handling convenience is poor, increasing the workload of sanitation workers.

[0005] Therefore, there is a particular need for a foldable sanitation waste collection bag support. Utility Model Content

[0006] The purpose of this invention is to provide a foldable sanitation waste collection bag support to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable sanitation waste collection bag support, comprising a support body, wherein a collection rack adjustment mechanism is installed on the upper surface of the support body;

[0008] The collection rack adjustment mechanism includes a support limiting collar, which is mounted on the support body. A support limiting rod is inserted into the inner surface of the support limiting collar. A connecting collar is movably connected to one side of the support limiting rod. A snap-fit ​​rod is movably connected to one side of the connecting collar. A garbage bag support frame is fixedly connected to one side of the connecting collar. A garbage bag clamping plate is fixedly connected to one side of the garbage bag support frame. A fixing block is fixedly connected to one side of the support limiting collar. A nut is fixedly connected to one side of the fixing block. A threaded rod is movably connected to one side of the nut.

[0009] Preferably, one side of the bracket body is fixedly connected with an anti-slip fixing foot, and there are multiple anti-slip fixing feet that are parallel to each other.

[0010] Preferably, one side of the support limiting collar has an insertion opening, and the size of the insertion opening and the support limiting rod are matched.

[0011] Preferably, the outer ring surface of the snap-fit ​​rod is fitted with a snap-fit ​​collar, and the snap-fit ​​collar and the snap-fit ​​rod are structurally compatible.

[0012] Preferably, a knob handle is fixedly connected to one side of the threaded rod, and the knob handle is connected to the threaded rod and a nut.

[0013] Preferably, the nut is connected between a fixing block and a supporting limiting collar, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0014] Preferably, a reinforcing plate is fixedly connected to one side of the main body of the bracket, and the reinforcing plate is connected to the supporting limiting collar.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The collection rack adjustment mechanism enables multi-dimensional flexible adjustment. The insertion and engagement of the support limiting rod and the support limiting collar, combined with the threaded connection of the threaded rod and the nut, allows for easy adjustment of the extension length of the support limiting rod, thereby changing the height of the garbage bag support frame. At the same time, the movable connection between the insertion collar and the support limiting rod, and the locking and fixing of the locking rod and the locking collar, enable the garbage bag support frame to be folded and unfolded for storage. This saves storage space when not in use and allows for flexible adjustment of the support frame shape according to different garbage collection scenarios to meet various usage needs.

[0017] 2. Multiple parallel anti-slip fixing feet at the bottom of the main body of the bracket enhance the friction when the bracket is placed, preventing the bracket from sliding or shifting due to collisions or increased weight of garbage during garbage collection. The clamping plate on one side of the garbage bag support frame can firmly fix the edge of the garbage bag, preventing the garbage bag from slipping or shifting when garbage is disposed of, thus improving collection efficiency. In addition, the symmetrically distributed fixing blocks make the connection between the nut and the support limiting collar more stable. The threaded adjustment structure is easy to operate, and the height and folding state can be switched without professional tools, reducing the difficulty of operation for sanitation workers and improving the convenience of operation.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a foldable sanitation garbage collection bag support, including a support body 1, and a collection rack adjustment mechanism 3 is installed on the upper surface of the support body 1;

[0025] The collection rack adjustment mechanism 3 includes a support limiting collar 301, which is mounted on the bracket body 1. A support limiting rod 303 is inserted into the inner ring surface of the support limiting collar 301. A connecting collar 304 is movably connected to one side of the supporting limiting rod 303. A snap-fit ​​rod 306 is movably connected to one side of the connecting collar 304. A garbage bag support frame 307 is fixedly connected to one side of the connecting collar 304. A garbage bag clamping plate 308 is fixedly connected to one side of the garbage bag support frame 307. A fixing block 309 is fixedly connected to one side of the support limiting collar 301. A nut 310 is fixedly connected to one side of the fixing block 309. A threaded rod 311 is movably connected to one side of the nut 310.

[0026] Furthermore, one side of the support body 1 is fixedly connected with anti-slip fixing feet 2, and there are multiple anti-slip fixing feet 2 that are parallel to each other. The multiple parallel anti-slip fixing feet 2 can evenly distribute the weight of the support body 1 and the structure above it, and increase the contact friction between the support and the ground. Even on uneven outdoor ground or when there is a collision during garbage disposal or the weight of the garbage increases, the support can be effectively prevented from sliding or shifting, providing a stable foundation support for the entire garbage collection operation and ensuring the safety of sanitation workers.

[0027] Furthermore, a plug-in opening 302 is provided on one side of the support limiting collar 301, and the plug-in opening 302 and the support limiting rod 303 are matched in size. The matching plug-in opening 302 ensures that the support limiting rod 303 can be accurately and smoothly inserted into the inner ring of the support limiting collar 301, avoiding jamming or shaking of the rod due to size deviation. At the same time, the tight plug-in fit enhances the stability of the connection between the two, providing a reliable structural basis for adjusting the extension length of the support limiting rod 303 and changing the height of the garbage bag support frame 307 through the threaded rod 311, ensuring that the height adjustment process is stable and controllable.

[0028] Furthermore, a snap-fit ​​collar 305 is fitted onto the outer surface of the snap-fit ​​rod 306, and the snap-fit ​​collar 305 and the snap-fit ​​rod 306 are structurally compatible. The snap-fit ​​collar 305 and the snap-fit ​​rod 306 form a tight limiting and fixing relationship. When the garbage bag support frame 307 is unfolded to a suitable angle through the snap-fit ​​collar 304, the snap-fit ​​rod 306 is inserted into the snap-fit ​​collar 305, which can firmly lock the relative position of the snap-fit ​​collar 304 and the support limiting rod 303, preventing the support frame from accidentally rotating or folding during garbage disposal, ensuring that the garbage bag support frame 307 is always in a stable supporting state, and preventing the garbage bag from slipping.

[0029] Furthermore, a knob handle 312 is fixedly connected to one side of the threaded rod 311, and the knob handle 312 is connected to the nut 310 through the threaded rod 311. The knob handle 312 provides a convenient force application point for the rotation of the threaded rod 311. Sanitation workers do not need to use professional tools. They can simply rotate the knob handle 312 by hand to push the support limiting rod 303 along the insertion opening 302 of the support limiting collar 301 to extend and retract, thus easily adjusting the height of the garbage bag support frame 307. This greatly reduces the difficulty of operation and improves work efficiency.

[0030] Furthermore, the nut 310 is connected to the fixing block 309 and the support limiting collar 301. The fixing blocks 309 are symmetrically arranged with the vertical center line of the nut 310 as the axis of symmetry. The symmetrical distribution of the fixing blocks 309 can evenly and firmly fix the nut 310 to one side of the support limiting collar 301, avoiding loosening of the connection due to uneven force on the nut 310. When the threaded rod 311 is rotated to adjust the support limiting insert 303, the symmetrical structure can disperse the force transmitted by the threaded rod 311, preventing the fixing block 309 or the support limiting collar 301 from deforming due to excessive local force, extending the service life of the components, and ensuring the long-term stable operation of the threaded adjustment structure.

[0031] Furthermore, a reinforcing plate 4 is fixedly connected to one side of the support body 1, and the reinforcing plate 4 is connected to the support limiting collar 301. The reinforcing plate 4 can form an additional support connection between the support body 1 and the support limiting collar 301, enhancing the firmness of the support limiting collar 301 installation. Since the support limiting collar 301 needs to bear the weight of the support limiting rod 303, the garbage bag support frame 307 and the garbage, the reinforcing plate 4 can distribute the pressure of these weights on the connection between the support limiting collar 301 and the support body 1, preventing the part from breaking or loosening due to long-term stress, and ensuring the stability and service life of the overall structure of the collection rack adjustment mechanism 3.

[0032] Working principle: When the user needs to use a foldable sanitation waste collection bag support, the support body 1 is placed on a flat working surface. Multiple parallel anti-slip fixing feet 2, fixedly connected to one side of the support body 1, increase the friction between the device and the ground, preventing the device from sliding or shifting during subsequent operations. Simultaneously, the reinforcing plate 4 connected to one side of the support body 1 enhances the stability of the support limiting collar 301, laying the foundation for subsequent adjustment operations. First, check the insertion opening 302 on one side of the support limiting collar 301 to confirm its connection with the support limiting rod 30. 3. After matching the size, insert the support limiting rod 303 into the inner ring of the support limiting collar 301; then rotate the knob handle 312 on one side of the threaded rod 311, utilizing the threaded engagement between the threaded rod 311 and the nut 310 on the fixing block 309, with the fixing blocks 309 symmetrically distributed along the vertical center line of the nut 310 to ensure a stable connection. Push the support limiting rod 303 to extend and retract along the insertion opening 302, adjusting it to a position suitable for the height of the sanitation-specific garbage collection bag. Rotate the insertion collar 304, which is movably connected on one side of the support limiting rod 303, outwards. The garbage bag support frame 307, fixed to one side of the movable insertion collar 304, unfolds; then, the snap-fit ​​rod 306 is passed through the insertion collar 304, and the outer surface of the snap-fit ​​rod 306 is structurally fitted with the snap-fit ​​collar 305. Through the limiting engagement of the snap-fit ​​rod 306 and the snap-fit ​​collar 305, the relative position of the insertion collar 304 and the supporting limiting rod 303 is fixed, preventing the garbage bag support frame 307 from shaking. The edge of the sanitation-specific garbage collection bag is then placed on the garbage bag support frame 307, and the garbage bag clamping plate fixed to one side of the garbage bag support frame 307 is used for clamping. 308 clamps the edge of the garbage bag to prevent it from slipping or shifting during garbage disposal. Once the garbage bag is installed and secured, garbage collection can begin. After the operation is completed, first remove the garbage bag, then pull out the snap-fit ​​rod 306 to release the locking collar 305 from the locking rod 306. Rotate the snap-fit ​​collar 304 inward to fold the garbage bag support frame 307. Rotate the knob handle 312 in the opposite direction to retract the support limiting rod 303 along the snap-fit ​​opening 302 into the support limiting collar 301, reducing the space occupied by the device and facilitating subsequent handling and storage.
