Description

Technical Field

[0001] This utility model relates to the technical field of material cart tipping platform, specifically a material cart tipping platform with a locking mechanism. Background Technology

[0002] Flip-over platforms are widely used in industrial production, warehousing and logistics, and transportation. Through their unique design and structure, they can quickly switch working states as needed to meet the demands of different working environments. Their surfaces are typically made of robust metal or other wear-resistant materials, ensuring they are not easily worn or damaged during prolonged use. In the logistics industry, flip-over platforms are frequently used for handling and loading / unloading. They can flexibly adjust their height or angle according to different transportation needs, improving work efficiency. For production line workers, flip-over platforms provide a flexible work area, helping them better complete tasks such as material handling and processing. Flip-over platforms are not only highly adaptable in their physical structure but can also be customized to meet specific operational requirements based on the work scenario. Their use in multiple industries has driven the development of automated and refined production processes, saved companies significant labor costs, and improved work safety.

[0003] Existing tipping platforms for material carts have significant drawbacks in practical use: when operators adjust the hopper to the required angle, the adjustment mechanism cannot automatically fix the current position due to the lack of an effective locking device. This structural design causes the hopper to easily shift in angle during unloading operations due to equipment vibration, material impact, or external interference, which not only affects unloading accuracy but may also lead to safety hazards such as material spillage or equipment damage. Utility Model Content

[0006] Preferably, a guide block is fixedly connected to the outer side of the base, and the guide block is slidably connected to the support base. Through the design of the guide block, the support base can be guided.

[0007] Preferably, a protrusion is fixedly connected to the outer side of the limiting block, and the protrusion is rotatably connected to the base. Through the design of the protrusion, the limiting block can play a limiting role.

[0008] Preferably, the limiting sleeve contacts the base, the limiting sleeve contacts the support bottom, and the limiting sleeve is connected to the support rod by a thread. Through the design of the limiting sleeve, the position of the support bottom can be adjusted.

[0009] Preferably, the limiting mechanism includes a push plate, a locking block is fixedly connected to the side of the push plate near the knob, a locking groove is opened inside the knob, a sliding rod is fixedly connected to the side of the push plate away from the locking block, the sliding rod is slidably connected to the base, a baffle is fixedly connected inside the base, the baffle is slidably connected to the sliding rod, and a spring is provided inside the base. Through the design of the limiting mechanism, the hopper can remain stable after adjustment.

[0010] Preferably, the locking block is slidably connected to the base and slidably connected to the slot. The design of the locking block can limit the movement of the knob.

[0011] Preferably, one end of the spring contacts the base, and the other end of the spring contacts the slide rod. Through the design of the spring, the locking block can be driven to limit the knob.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model innovatively designs a push plate, a locking block, and a spring linkage mechanism. The spring force drives the push plate to automatically engage the locking block into the knob slot, achieving precise locking of the knob and effectively fixing the position of the threaded rod.

It can ensure that the hopper is stable and does not shift after the angle of the hopper is adjusted, and completely solves the problem of easy loosening and position displacement of the hopper caused by the lack of an effective locking device in traditional material cart flip-plate platforms.

[0013] 2. This utility model features an optimized support adjustment mechanism, consisting of a support rod, a support base, and a limiting sleeve. By screwing the limiting sleeve, the threaded engagement between it and the support rod is activated, causing the support rod to move axially, thereby precisely adjusting the spatial position of the support base. This mechanism allows for flexible adjustment of the base support point distribution, enhancing stability during hopper operation and effectively solving the problem of uneven force distribution caused by fixed support points in traditional structures.

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.

[0017] Please see Figure 1-5 A material cart tipping platform with a locking mechanism includes a base 1, a hinge frame 2 fixedly connected to the outer side of the base 1, a hopper 21 hinged inside the hinge frame 2, a fixing frame 22 fixedly connected to the lower end of the hopper 21, a hinge rod 23 hinged inside the fixing frame 22, a connecting frame 24 hinged to the end of the hinge rod 23 away from the fixing frame 22, a connecting sleeve 25 fixedly connected to the lower end of the connecting frame 24, the connecting sleeve 25 being slidably connected to the base 1, and a threaded rod 26 connected inside the base 1 via a bearing, the threaded rod 26 being threadedly connected to the connecting sleeve 25.

[0018] Please see Figure 2-5 The base 1 has a support rod 3 slidably connected inside, and a support base 31 is fixedly connected to the lower end of the support rod 3. A guide block 32 is fixedly connected to the outer side of the base 1, and the guide block 32 is slidably connected to the support base 31. The guide block 32 guides the support base 31. A limit block 33 is rotatably connected inside the base 1, and the limit block 33 is rotatably connected to the support rod 3. A protrusion 34 is fixedly connected to the outer side of the limit block 33, and the protrusion 34 is rotatably connected to the base 1. The protrusion 34 limits the limit block 33. A limit sleeve 35 is fixedly connected to the lower end of the limit block 33. The limit sleeve 35 contacts the base 1 and the support base 31. The limit sleeve 35 is threadedly connected to the support rod 3. The position of the support base 31 can be adjusted by the limit sleeve 35. A limit mechanism 4 is provided on the base 1.

[0019] Please see Figure 2-5 The limiting mechanism 4 includes a push plate 41. A locking block 42 is fixedly connected to the side of the push plate 41 near the knob 27. A locking groove 43 is opened inside the knob 27. The locking block 42 is slidably connected to the base 1 and the locking block 42 is slidably connected to the locking groove 43. Through the design of the locking block 42, the knob 27 can be limited. A sliding rod 44 is fixedly connected to the side of the push plate 41 away from the locking block 42. The sliding rod 44 is slidably connected to the base 1. A baffle 45 is fixedly connected inside the base 1. The baffle 45 is slidably connected to the sliding rod 44. A spring 46 is set inside the base 1. One end of the spring 46 contacts the base 1, and the other end of the spring 46 contacts the sliding rod 44. Through the design of the spring 46, the locking block 42 can be driven to limit the knob 27. Through the design of the limiting mechanism 4, the hopper 21 can remain stable after adjustment.

[0020] The specific implementation process of this utility model is as follows: When in use, by rotating the limiting sleeve 35, the limiting sleeve 35 and the support rod 3 will undergo threaded movement, causing the support rod 3 to move within the limiting sleeve 35, thereby causing the support rod 3 to drive the support base 31 to move, thus adjusting the position of the support base 31, thereby adjusting the support point of the base 1, so that the base 1 remains stable when placed. By moving the push plate 41 away from the knob 27, the push plate 41 causes the slide rod 44 to slide within the baffle 45, which in turn compresses the spring 46. This causes the push plate 41 to move the locking block 42 out of the slot 43 on the knob 27, thus releasing the limitation on the knob 27. By rotating the knob 27, the knob 27 drives the threaded rod 26 to rotate, causing the threaded rod 26 and the connecting sleeve 25 to move in a threaded motion. This causes the connecting sleeve 25 to move on the threaded rod 26, and the connecting sleeve 25 drives the hinge rod 23 to move through the connecting frame 24. The hinge rod 23 drives the hopper 21 to move through the fixed frame 22, thus adjusting the angle of the hopper 21. Then, by releasing the push plate 41, the spring force of the spring 46 can drive the slide rod 44 to move, which in turn drives the push plate 41 to move. This causes the push plate 41 to drive the locking block 42 to slide into the locking groove 43 on the knob 27, thus resetting the knob 27 and keeping the hopper 21 stable after adjustment.
