Description

Technical Field

[0001] This utility model relates to the field of sanitation equipment technology, and in particular to a garbage can fixing device for garbage trucks. Background Technology

[0002] Garbage trucks play a crucial role in urban sanitation operations by collecting and transporting garbage bins (trash cans). During the dumping process, the garbage bins need to be lifted to the top of the truck using an onboard lifting mechanism for tipping and emptying.

[0003] In the existing technology, the fixing methods of the connection bracket between the garbage can and the garbage truck are generally inadequate. There are two common types: one is a simple hook or snap-fit ​​structure, which has limited fixing force. When the garbage can is raised, flipped or transported, it is easy to loosen, shake or even fall off, which not only affects the smoothness of operation, but also poses a huge safety hazard. Another type is a structure that relies on manual locking operations. This method not only significantly reduces operational efficiency and increases the labor intensity of sanitation workers, but also makes it easy to cause safety accidents in the complex environment of garbage stations.

[0004] Therefore, this utility model provides a garbage bin fixing device for garbage trucks to solve one or more of the above-mentioned problems. Utility Model Content

[0005] This utility model provides a garbage bin fixing device for garbage trucks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution, including: a fixed arm assembly, a positioning groove recessed inward on the side of the garbage bin near the connecting bracket, a mounting sleeve connected to the connecting bracket by bolts, a drive motor installed inside the mounting sleeve, and several sets of fixed arm assemblies installed around the mounting sleeve.

[0007] Preferably, the drive motor is embedded in the mounting sleeve housing, and a main bevel gear is fixedly sleeved on the output shaft of the drive motor.

[0008] Preferably, the fixed arm assembly consists of four sets arranged around the main bevel gear.

[0009] Preferably, the fixed arm assembly includes: a fixed arm, which is rotatably connected to the inner wall of the mounting sleeve via a drive shaft, a fastening pressure plate is movably provided at one end of the fixed arm, and a limiting ring is formed by extending one end of the fixed arm.

[0010] Preferably, the limiting ring is provided with a first clearance groove and a second clearance groove that pass through each other.

[0011] Preferably, the driving component is cylindrical and is movably inserted into the limiting ring component.

[0012] Preferably, a secondary bevel gear is fixedly sleeved at one end of the drive screw, and the other end of the drive screw passes through the clearance groove and is threadedly connected to the drive component.

[0013] Preferably, the main bevel gear meshes with the secondary bevel gear.

[0014] Preferably, a torsion spring for resetting is installed on the connecting shaft between the fastening plate and the fixed arm.

[0015] Preferably, the outer wall of the mounting sleeve is provided with an elongated slot for avoiding the fixed arm.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The garbage truck's garbage bin fixing device uses a drive motor to drive a bevel gear and screw system, automatically controlling the opening and clamping actions of four sets of fixing arms to reliably fix the garbage bin in the positioning groove. This provides a stable and firm fixing effect during the lifting and dumping of the garbage truck, avoids jamming and failure, and ensures the safe and efficient lifting operation.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-4 This utility model provides a technical solution, including: a fixed arm assembly 6; a positioning groove 16 recessed inward on the side of the garbage bin 1 near the connecting bracket 2; a mounting sleeve 3 connected to the connecting bracket 2 by bolts; a drive motor 4 installed inside the mounting sleeve 3; and several sets of fixed arm assemblies 6 installed around the mounting sleeve 3. By integrating the fixed arm assembly, the positioning groove, and the drive motor, the garbage bin can be quickly and automatically clamped and released, ensuring that the garbage bin is firmly fixed when the garbage truck is raised, lowered, and tilted, reducing the risk of falling off and improving operational efficiency.

[0024] Furthermore, the drive motor 4 is embedded within the housing of the mounting sleeve 3, and a main bevel gear 5 is fixedly sleeved on the output shaft of the drive motor 4. The embedded design protects the drive motor from external impacts and dust, while the main bevel gear ensures efficient power transmission, improves the compactness and service life of the mechanism, and prevents motor failure.

[0025] Furthermore, the fixed arm assembly 6 consists of four sets arranged around the main bevel gear 5. This four-set arrangement provides multi-directional balanced clamping force, preventing the garbage bin from tilting or swaying, ensuring uniform force distribution during lifting and lowering, and increasing stability and safety.

[0026] Furthermore, the fixed arm assembly 6 includes a fixed arm 9, which is rotatably connected to the inner wall of the mounting sleeve 3 via a drive shaft 12. A fastening pressure plate 15 is movably mounted at one end of the fixed arm 9, and a limiting ring 10 extends from the other end of the fixed arm 9. The lever design amplifies the clamping force, and the limiting ring constrains the movement path, achieving efficient clamping and releasing operations and improving the response speed and mechanical efficiency of the fixed arm.

[0027] Furthermore, the limiting ring 10 is provided with two through-hole clearance grooves, namely, clearance groove 13 and clearance groove 14. The clearance grooves avoid interference when the drive components move, ensure smooth operation of the mechanism, reduce the risk of jamming and failure, and extend the service life of the components.

[0028] Furthermore, the drive component 11 is cylindrical and is movably inserted into the limiting ring component 10. The cylindrical shape and insertion method restrict the rotational freedom of the drive component, ensuring its precise linear movement under the screw drive, realizing smooth rotation of the fixed arm, and improving control accuracy.

[0029] Furthermore, a secondary bevel gear 7 is fixedly sleeved at one end of the drive screw 8, and the other end of the drive screw 8 passes through the clearance groove 13 and is threadedly connected to the drive component 11. The threaded connection converts the rotational motion of the bevel gear into the linear displacement of the drive component, precisely controlling the opening and closing angle of the fixed arm and improving the consistency and adjustability of the clamping force.

[0030] Furthermore, the main bevel gear 5 meshes with the secondary bevel gear 7. This gear meshing provides high torque transmission efficiency, ensuring reliable power transfer from the drive motor to the fixed arm, adapting to installations in confined spaces, and enhancing system reliability and noise control.

[0031] Furthermore, a torsion spring for resetting is installed on the connecting shaft between the fastening plate 15 and the fixed arm 9. When the torsion spring is released, it automatically resets the fastening plate, simplifying the loading and unloading of the garbage bin, reducing manual intervention, improving efficiency, and preventing residual deformation of components.

[0032] Furthermore, the outer wall of the mounting sleeve 3 is provided with an elongated slot for avoiding the fixed arm 9. The slot provides rotational clearance space to prevent the fixed arm from colliding or getting stuck with the mounting sleeve, ensuring free movement at a maximum rotation angle of 40 degrees, and guaranteeing the durability and safety of the mechanism.

[0033] Preferably, the drive motor 4 model can be any one of TZ180XSF or TZ184XYA2001.

[0034] The working principle and beneficial effects of the above scheme are as follows: In use, after aligning the four sets of fixed arms 9 with the positioning slots 16 opened on the back of the garbage bin 1 and inserting them, the drive motor 4 is started to drive the main bevel gear 5 to rotate. At the same time, the main bevel gear 5 rotates and drives the drive screw 8 to rotate through the secondary bevel gear 7. Since the drive component 11 is restricted within the limiting ring 10, the drive screw 8 rotates and drives the drive component 11 to move along the drive screw 8 towards the secondary bevel gear 7. Since the fixed arms 9 are connected to the inner wall of the mounting sleeve 3 through the drive shaft 12 to form a lever structure, when the drive component 11 moves along the drive screw 8, it drives the fixed arms 9 to rotate around the drive shaft 12, so that the four sets of fixed arms 9 rotate in a direction away from each other until the fastening pressure plate 15 is tightly attached to the inner wall of the positioning slot 16, thus completing the fixing of the garbage bin 1. Then, the garbage bin 1 can be lifted and tilted by the lifting mechanism on the garbage truck through the connecting bracket 2.

[0035] The outer wall of the mounting sleeve 3 is provided with four sets of long strip slots to provide clearance space when the fixed arm 9 rotates. The diameters of the drive screw 8 and the drive component 11 are smaller than the clearance slot 13 and clearance slot 2 14 to avoid jamming or failure and to provide clearance space for the rotation of the fixed arm 9. The maximum allowable rotation angle of the fixed arm 9 driven by the drive motor 4 is 40 degrees.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
