This simulates the mixing process of the cement mixer truck and further enhances the playability of the toy car.
[0007] Preferably, the connecting mechanism includes a rotating shaft and a screw, the rotating shaft being rotatably connected to the front support, the rotating shaft having a threaded hole, the screw being threadedly connected within the threaded hole, and the screw being fixedly connected to the mixing barrel. The present invention utilizes the threaded connection between the screw and the rotating shaft so that the mixing barrel can be fixed to the rotating shaft by the screw and rotated by the rotating shaft, and can also be separated from the rotating shaft by relative rotation with the rotating shaft to achieve disassembly.
[0008] Preferably, the drive mechanism includes a worm wheel and a worm, the worm wheel and the worm being meshed with each other, the worm wheel being fixedly connected to the rotating shaft, and the worm being rotatably connected to the front support. The present invention utilizes the meshing of the worm wheel and the worm to rotate the worm wheel by rotating the worm, and then transmits the rotation to the mixing drum through the fixed connection between the worm wheel and the rotating shaft, thereby driving the mixing drum. At the same time, the self-locking ability of the worm wheel and the worm is utilized to make it difficult for the mixing drum to rotate without being driven by the worm, thereby facilitating the rotational disassembly of the mixing drum.
[0009] Preferably, the front wheels are rotatably connected to the vehicle body via a wheel axle, and the wheel axle is connected to the worm gear via a transmission mechanism. In this way, the present invention enables the vehicle body to synchronously drive the mixing drum to rotate when the vehicle body moves via the front wheels, thereby further enhancing the playability of the toy car.

The utility model utilizes a belt to transmit the rotation of the wheel shaft to the driving wheel, and the driving wheel then transmits the rotation to the driven wheel via the belt. The driven wheel and the worm are transmission-connected, so the rotation of the driven wheel can be transmitted to the worm, thereby realizing the linkage between the front wheel and the worm.
[0011] Preferably, the front support is rotatably connected to a turntable, the turntable is provided with a handle, and the turntable is transmission-connected to the worm. The utility model utilizes the turntable and the handle to drive the worm from the outside of the front support, making the rotation more labor-saving and convenient.
[0012] Preferably, the driven wheel and the turntable are both connected to the worm gear through a clutch mechanism. The utility model utilizes a clutch mechanism to make the driving of the worm gear by the front wheel and the driving of the worm gear by the turntable independent of each other, thereby avoiding the need for the turntable to drive the worm gear while the vehicle body moves forward, without affecting the operation and enhancing the fun.

The sliding rod of the utility model has only the part that cooperates with the worm gear with a non-circular cross-section, and there is a certain gap between the sliding rod and the driven wheel and the turntable. Therefore, in the state without other connection relationships, the sliding rod will not drive the turntable and the driven wheel to rotate. Connecting cylinders are provided on the driven wheel and the turntable. The transmission block is made of silicone or rubber material and can utilize its own deformation to embed into the connecting cylinder, so that the friction between the transmission block and the connecting cylinder can be used to transmit the rotation of the sliding rod to the turntable or the driven wheel, thereby realizing the transmission relationship between the driven wheel or the turntable and the worm gear. The sliding rod can slide, and when sliding, one of the transmission blocks can be disengaged from the connecting cylinder, and the other transmission block can be embedded in the other connecting cylinder, thereby realizing the switching of the connection relationship, so that the linkage relationship between the worm gear and the turntable and the linkage relationship between the worm gear and the driven wheel are independent of each other.
[0014] Preferably, the transmission block is provided with a conical surface at one end thereof facing the inlet of the connecting cylinder. The utility model utilizes the conical surface to make it easier for the transmission block to be embedded in the connecting cylinder.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.
[0029] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0030] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, removable connections, or integration; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or interaction between two components. However, the term "direct connection" indicates that the two connected entities are not connected through a transitional structure, but are connected solely through a connecting structure to form a single entity. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0031] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0032] like Figure 1-3 As shown, a cement mixer truck toy with feeding and discharging functions includes a body 1, front wheels 2, rear wheels 3, a loading plate 4 and a mixing barrel 5. The loading plate 4 is fixedly connected to the body 1, and the two ends of the loading plate 4 are respectively fixedly connected to the front support 6 and the rear support 7. The mixing barrel 5 is rotatably connected to the front support 6 through a connecting mechanism. A driving mechanism for driving the mixing barrel 5 to rotate is provided in the front support 6. The driving mechanism is transmission-connected to the mixing barrel 5 through the connecting mechanism. An opening is opened at one end of the mixing barrel 5, and the opening is closed by a sealing plug 8. The sealing plug 8 is threadedly connected to the mixing barrel 5.
[0033] By adopting the above technical solution, the driving mechanism can drive the mixing barrel 5 to rotate, thereby simulating a cement mixer truck and enhancing the playability of the toy car. The mixing barrel 5 can be removed by a connecting mechanism. An opening is provided at one end of the mixing barrel 5, through which sand, water and other items can be placed. The opening is then sealed by a threaded connection between the sealing plug 8 and the mixing barrel 5, and then reinstalled on the front support 6 through the connecting mechanism. This can simulate the mixing process of the cement mixer truck and further enhance the playability of the toy car.
[0034] The connection mechanism includes a rotating shaft 9 and a screw 10. The rotating shaft 9 is rotatably connected to the front support 6. The rotating shaft 9 has a threaded hole, and the screw 10 is threadedly connected to the threaded hole. The screw 10 is fixedly connected to the mixing barrel 5. The threaded connection between the screw 10 and the rotating shaft allows the mixing barrel 5 to be fixed to the rotating shaft 9 by the screw 10 and rotated by the rotating shaft 9. It can also be separated from the rotating shaft 9 by relative rotation with the rotating shaft 9 to achieve disassembly.
[0035] The drive mechanism includes a worm gear 11 and a worm 12, which mesh with each other. The worm gear 11 is fixedly connected to the rotating shaft 9, and the worm 12 is rotationally connected to the front support 6. The meshing of the worm gear 11 and the worm 12 allows the worm gear 11 to rotate by rotating the worm 12. The rotation is then transmitted to the mixing drum 5 through the fixed connection between the worm gear 11 and the rotating shaft 9, thereby driving the mixing drum 5. At the same time, the self-locking ability of the worm gear 11 and the worm 12 makes it difficult for the mixing drum 5 to rotate without being driven by the worm 12, thereby facilitating the rotational disassembly of the mixing drum 5.
[0036] The front wheel 2 is rotatably connected to the vehicle body 1 via the axle 13, and the axle 13 is transmission-connected to the worm 12 via a transmission mechanism. In this way, when the vehicle body 1 moves via the front wheel 2, the mixing drum 5 can be synchronously driven to rotate, thereby further enhancing the playability of the toy car.
[0037] The transmission mechanism includes a driving wheel 14 and a driven wheel 15. The driven wheel 15 is rotationally connected to the front support 6, the driving wheel 14 is rotationally connected to the vehicle body 1, and the driving wheel 14 is transmission-connected to the wheel shaft 13 via a belt 16. The driving wheel 14 is transmission-connected to the driven wheel 15 via the belt 16, and the driven wheel 15 is transmission-connected to the worm gear 11. The belt 16 transmits the rotation of the wheel shaft 13 to the driving wheel 14, and the driving wheel 14 transmits the rotation to the driven wheel 15 via the belt 16. The driven wheel 15 is transmission-connected to the worm 12, so the rotation of the driven wheel 15 can be transmitted to the worm 12, thereby realizing the linkage between the front wheel 2 and the worm 12.
[0038] The front support 6 is rotatably connected with a turntable 17, on which a handle 18 is provided, which is in transmission connection with the worm 12. The worm 12 can be driven from the outside of the front support 6 by the turntable 17 and the handle 18, so that rotation is more labor-saving and convenient.
[0039] The driven wheel 15 and the turntable 17 are both connected to the worm 12 via a clutch mechanism. The clutch mechanism makes the driving of the worm 12 by the front wheel 2 and the driving of the worm 12 by the turntable 17 independent of each other, thereby avoiding the vehicle body 1 moving forward by driving the worm 12 by the turntable 17, which does not affect the operation and can enhance the fun.
[0040] The clutch mechanism includes a slide rod 19, two transmission blocks 20 and two connecting cylinders 21. The slide rod 19 passes through the turntable 17, the worm 12 and the driven wheel 15, and the slide rod 19 is slidingly connected to the turntable 17, the worm 12 and the driven wheel 15. The two connecting cylinders 21 are fixedly connected to the turntable 17 and the driven wheel 15 respectively. One of the transmission blocks 20 is embedded in one of the connecting cylinders 21, and the other transmission block 20 is located at the entrance of the other connecting cylinder 21. Both transmission blocks 20 are fixedly connected to the slide rod 19. The cross-section of the matching part of the slide rod 19 and the worm 12 is a non-circular cross-section, and the cross-section of the matching part of the slide rod 19 and the turntable 17 and the transmission wheel 14 is a circular cross-section. The sliding rod 19 has only a non-circular cross-section at the part that cooperates with the worm 12, and there is a certain gap between the sliding rod 19 and the driven wheel 15 and the turntable 17. Therefore, when there is no other connection relationship, the sliding rod 19 will not drive the turntable 17 and the driven wheel 15 to rotate. A connecting cylinder 21 is provided on the driven wheel 15 and the turntable 17. The transmission block 20 is made of silicone or rubber material and can be embedded in the connecting cylinder 21 by its own deformation, so that the friction between the transmission block 20 and the connecting cylinder 21 can be used to transmit the rotation of the sliding rod 19 to the turntable 17 or the driven wheel 15, thereby realizing the transmission relationship between the driven wheel 15 or the turntable 17 and the worm 12. The sliding rod 19 can slide, and when sliding, one of the transmission blocks 20 can be disengaged from the connecting cylinder 21, and the other transmission block 20 can be embedded in the other connecting cylinder 21, thereby realizing the switching of the connection relationship, so that the linkage relationship between the worm 12 and the turntable 17 and the linkage relationship between the worm 12 and the driven wheel 15 are independent of each other.
[0041] A conical surface is provided on one end of the transmission block 20 facing the inlet of the connecting cylinder 21. The conical surface makes it easier for the transmission block 20 to be embedded in the connecting cylinder 21.
[0042] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
