[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0035] With the increasing urbanization rate and the rapid growth of the urban resident population, the amount of domestic waste is also increasing. Therefore, the efficiency and reliability of garbage trucks are also being improved. Currently, the main method of garbage transfer is to use detachable garbage trucks to hook horizontal or vertical garbage containers onto the truck, then secure them with locking devices to prevent movement, before transporting them to landfills or power plants for unloading. However, the locking devices for detachable garbage trucks currently involve many complex structures, resulting in high costs and large space requirements.
[0036] Based on this, please refer to Figure 1 , Figure 2 and Figure 3The locking device 100 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This locking device 100 can lock using a purely mechanical structure, simplifying the structure, saving costs, and reducing the space occupied by the locking device 100. This locking device 100 is applied to garbage trucks 1000 or other equipment requiring locking. All equipment with this locking device 100 has the same functions as described above, and will not be elaborated further here.
[0037] Figure 1 This is a schematic diagram of the garbage truck 1000 in the locked state of the garbage bin 300 provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of a garbage truck 1000 in an unlocked state, provided in an embodiment of the present invention; Figure 4 This is an enlarged schematic diagram of the first state at point A provided in an embodiment of this utility model; Figure 5 This is an enlarged schematic diagram of the second state at point A provided in an embodiment of this utility model.
[0038] Please see Figure 1 and Figure 2 and combined Figure 4 and Figure 5 In this embodiment, the garbage truck 1000 includes a vehicle body 200, a garbage bin 300, a limiting beam 400, and a locking device 100. The garbage bin 300 is movably mounted on the vehicle body 200, and the limiting beam 400 is mounted on the garbage bin 300. A limiting seat 110 is connected to the vehicle body 200. When the garbage bin 300 is locked, the limiting beam 400 is engaged in the limiting groove 111, and the locking hook 120 rotates to block the limiting groove 111. After the garbage bin 300 rotates to lift and dump garbage, it needs to rotate back to a state where the bottom of the garbage bin 300 is in parallel contact with the chassis 210 of the vehicle body 200. During the transportation of the garbage bin 300, in order to prevent the garbage bin 300 from moving, by rotating the garbage bin 300 back to the bottom in parallel contact with the chassis 210 of the vehicle body 200, the limiting beam 400 on the garbage bin 300 rotates into the limiting groove 111, restricting the left and right movement of the garbage bin 300. To prevent the trash can 300 from moving up and down, the locking hook 120 is rotated to block the limiting groove 111, thereby locking the limiting beam 400 within the entire locking device 100 and fixing the trash can 300. In this embodiment, the limiting beam 400 is located on the side wall of the trash can 300. Of course, the limiting beam 400 can also be located in other positions on the trash can 300, as long as it can cooperate with the limiting groove 111 of the locking device 100. The locking hook 120 can be rotated manually or by using a mechanical structure for pressing and rotating, which is not limited here.
[0039] The aforementioned "garbage bin 300 is movably mounted on the vehicle body 200" specifically refers to the vehicle body 200 being movably connected to the garbage bin 300 via a pull arm 600 in this embodiment. The pull arm 600 in this embodiment includes a pull arm body 610, a base frame 620, and a locking device 100. One end of the pull arm body 610 is hinged to the base frame 620, and the other end is movably connected to the garbage bin 300. A limiting seat 110 is disposed on the base frame 620. In this embodiment, the pull arm body 610 is a telescopic rod structure, such as a hydraulic cylinder, pneumatic cylinder, or electric push rod, etc., and is not limited thereto.
[0040] That is, the garbage truck 1000 provided in the embodiment of this utility model includes a vehicle body 200, a garbage bin 300, a limiting crossbeam 400, and a pull arm 600. The vehicle body 200 is connected to the base frame 620. One end of the pull arm body 610 is hinged to the base frame 620, and the other end of the pull arm body 610 is movably connected to the garbage bin 300. Part of the garbage bin 300 is hinged to the vehicle body 200. The pull arm body 610 rotates relative to the base frame 620, thereby driving the garbage bin 300 to rotate relative to the vehicle body 200. The limiting crossbeam 400 is disposed on the garbage bin 300; the limiting seat 110 is connected to the vehicle body 200; when the garbage bin 300 is locked, the limiting crossbeam 400 is engaged in the limiting groove 111, and the locking hook 120 rotates to cover the limiting groove 111. After the garbage bin 300 is rotated to lift and empty the garbage, it needs to rotate back to a state where the bottom of the garbage bin 300 is in parallel contact with the chassis 210 of the vehicle body 200. During the transportation of the garbage bin 300, in order to prevent the garbage bin 300 from moving around, by rotating the garbage bin 300 back to the bottom and making parallel contact with the chassis 210 of the vehicle body 200, the limiting beam 400 on the garbage bin 300 rotates into the limiting groove 111, restricting the left and right movement of the garbage bin 300. To prevent the garbage bin 300 from moving up and down, the locking hook 120 is rotated to block the limiting groove 111, thereby locking the limiting beam 400 within the entire locking device 100, thus fixing the garbage bin 300.
[0041] Please continue reading. Figure 1 and Figure 2 and combined Figure 4 and Figure 5To simplify the locking operation and improve convenience, the garbage truck 1000 in this embodiment also includes a pressure bar 500 and a pull arm 600. The vehicle body 200 is movably connected to the garbage container 300 via the pull arm 600. The pressure bar 500 is located at the bottom of the garbage container 300 or on the pull arm 600. When the limiting beam 400 is close to the limiting groove 111, the pressure bar 500 presses down on the locking hook 120, causing the locking hook 120 to rotate relative to the limiting seat 110. This allows the locking hook 120 to rotate to cover the limiting groove 111 when the limiting beam 400 is engaged in the limiting groove 111. Without external force, the locking hook 120 exposes the opening of the limiting groove 111. When the bottom of the garbage bin 300 rotates to make parallel contact with the chassis 210 of the vehicle body 200, the limiting crossbeam 400 engages with the limiting groove 111. Simultaneously, the pressure rod 500 presses the locking hook 120 to rotate relative to the limiting seat 110, rotating until the locking hook 120 covers the limiting groove 111, thus limiting and fixing the garbage bin 300. When the garbage bin 300 is lifted upwards, the pressure rod 500 disengages from the locking hook 120 and no longer applies pressure to the locking hook 120. At this time, the locking hook 120 automatically rotates back to its initial state without external force, exposing the opening of the limiting groove 111. The limiting crossbeam 400 moves out of the limiting groove 111, and the garbage bin 300 is no longer locked, allowing garbage to be dumped. The pressure rod 500 can be set in other positions on the garbage bin 300, depending on the position of the locking device 100, and is not limited here.
[0042] The locking device 100 will be described in detail below.
[0043] Figure 3 This is a schematic diagram of the locking hook 120 provided in an embodiment of this utility model. Please refer to... Figure 3 and combined Figure 4 and Figure 5 In this embodiment, the locking device 100 includes a limiting seat 110 and a locking hook 120. The limiting seat 110 has a limiting groove 111 for engaging the part to be locked. The locking hook 120 is rotatably connected to the limiting seat 110. During the relative rotation of the locking hook 120 with respect to the limiting seat, the locking hook 120 can cover or expose the opening of the limiting groove 111. When the part to be locked, such as the limiting beam 400 of the trash can 300, is placed into the limiting groove 111, the locking hook 120 is rotated so that it rotates relative to the limiting seat 110, thereby covering the opening of the limiting groove 111. When the part to be locked is not engaged in the limiting groove 111, the locking hook 120 rotates to expose the opening of the limiting groove 111 so that the part to be locked can be engaged. The above design allows for locking using a purely mechanical structure, simplifying the structure, saving costs, and reducing the space occupied by the locking device 100.
[0044] Since the locking device 100 in this embodiment is mainly used on the garbage truck 1000, the garbage bin 300 is rotatably connected to the vehicle body 200. The garbage bin 300 will rotate to lift and dump garbage, and after dumping, it will rotate back to a state where the bottom of the garbage bin 300 is in parallel contact with the chassis 210 of the vehicle body 200. Therefore, in order to facilitate locking the garbage bin 300, a limiting groove 111 is provided on the top of the limiting seat 110 in this embodiment. This design allows the limiting crossbeam 400 of the garbage bin 300 to be directly engaged in the limiting groove 111. In addition, the limiting groove 111 can also be provided on the side of the limiting seat 110. Of course, the limiting groove 111 can also be provided on the bottom of the limiting seat 110, depending on the movement state of the part to be locked, and is not limited here.
[0045] Please continue reading. Figure 3 and combined Figure 4 and Figure 5 To facilitate the quick and easy insertion of the locking component, such as the limiting beam 400, into the limiting groove 111, the limiting seat 110 in this embodiment includes a seat body 112, a first locking part 113, and a second locking part 114. The first locking part 113 and the second locking part 114 are spaced apart and connected to the seat body 112, forming a limiting groove 111 between them. The distance between the first locking part 113 and the second locking part 114 gradually increases from near the seat body 112 to far away from it. This design reduces the resistance to insertion into the limiting groove 111 and also provides a certain guiding effect, reducing manual adjustment time and improving assembly efficiency. Of course, the distance between the first locking part 113 and the second locking part 114 can also be set to be equal everywhere.
[0046] Specifically, in this embodiment, the first locking part 113 is perpendicularly connected to the base 112, and the second locking part 114 is connected to the base 112 at an obtuse angle. This design restricts the left and right movement of the limiting beam 400 waiting for the locking member, and securely holds the limiting beam 400 waiting for the locking member. Of course, the first locking part and the second locking part 114 can also be connected to the base 112 at an obtuse angle simultaneously, or one of the locking parts can be connected to the base 112 at a right angle or an acute angle, and the other locking part can be connected to the base 112 at an obtuse angle; this is not limited here.
[0047] In addition, please see Figure 3In this embodiment, a limiting bolt 115 is provided on the limiting seat 110, and the limiting bolt 115 is located on the rotation path of the locking hook 120. The limiting bolt 115 is used to limit the rotation angle of the locking hook 120. Because the limiting bolt 115 is located on the rotation path of the locking hook 120, when the portion of the locking hook 120 rotates to abut against the limiting bolt 115, the locking hook 120 cannot continue to rotate relative to the limiting seat 110. The limiting bolt 115 can prevent the locking hook 120 from rotating too much, avoiding blocking the limiting groove 111. Simultaneously, the setting of the limiting bolt 115 can also ensure the initial position of the locking hook 120, ensuring that the pressure rod 500 can press against the portion of the locking hook 120, so that the locking hook 120 can rotate relative to the limiting seat 110.
[0048] Please see Figure 3 and combined Figure 4 and Figure 5 In this embodiment, the locking hook 120 includes a connecting part 121 and a hook body 122. The connecting part 121 is connected to the hook body 122. The connecting part 121 is rotatably connected to the limiting seat 110, and the hook body 122 is used to cover the opening of the limiting groove 111. Specifically, the hook body 122 in this embodiment is L-shaped. The hook body 122 includes a first locking part 1221 and a second locking part 1222 connected in sequence. The first locking part 1221 is perpendicularly connected to the connecting part 121, and the second locking part 1222 is parallel to the connecting part 121. The hook body 122 designed in this way can effectively cover the opening of the limiting groove 111 to limit the locking part in multiple directions, ensuring the stability and firmness of the locking. Of course, the hook body 122 can also be set into other structural shapes such as polygons, and the end of the hook body 122 can be bent to form an arc-shaped hook. The shape of the hook body 122 is determined according to the actual locking situation and is not limited here.
[0049] Please continue reading. Figure 3 and combined Figure 4 and Figure 5 To facilitate manual or other structural rotation of the locking hook 120, a pressing and rotating part 123 protrudes from the end of the connecting part 121 away from the hook body 122 in this embodiment. Furthermore, to ensure a tight fit between the pressing rod 500 and the pressing and rotating part 123 during pressing, the pressing and rotating part 123 in this embodiment has an inclined plane 1231, which slopes downwards from near the hook body 122 to away from it. This design also brings the center of gravity of the entire locking hook 120 closer to the hook body 122, allowing the locking hook 120 to automatically rotate to the position of the exposed limiting groove 111 without external force. Additionally, anti-slip textures can be provided on the inclined surface to further prevent the pressing rod 500 from slipping relative to the pressing and rotating part 123.
[0050] The working principle of the locking device 100 provided in this embodiment is as follows:
[0051] When the locking component, such as the limiting beam 400 of the trash can 300, is placed into the limiting groove 111, the locking hook 120 is rotated so that it rotates relative to the limiting seat 110, thereby blocking the opening of the limiting groove 111. When the locking component is not engaged in the limiting groove 111, the locking hook 120 is rotated until the opening of the limiting groove 111 is exposed, so that the locking component can be engaged.
[0052] In summary, the locking device 100 includes a limiting seat 110 and a locking hook 120. The limiting seat 110 has a limiting groove 111 for engaging the part to be locked. The locking hook 120 is rotatably connected to the limiting seat 110. During the relative rotation of the locking hook 120 with respect to the limiting seat, the locking hook 120 can cover or expose the opening of the limiting groove 111. When the part to be locked, such as the limiting beam 400 of the trash can 300, is placed into the limiting groove 111, the locking hook 120 is rotated to rotate relative to the limiting seat 110, so that the locking hook 120 covers the opening of the limiting groove 111. When the part to be locked is not engaged in the limiting groove 111, the locking hook 120 rotates to expose the opening of the limiting groove 111 so that the part to be locked can be engaged. The above design allows for locking using a purely mechanical structure, simplifying the structure, saving costs, and reducing the space occupied by the locking device 100.
[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
