Description

Technical Field

[0001] This utility model relates to the field of material transportation, specifically a material trolley positioning and locking mechanism. Background Technology

[0002] Refractory bricks are special bricks made from refractory clay or other refractory materials and have high refractoriness.

[0003] In the production process of refractory bricks, material trolleys are often used to transfer refractory bricks or raw materials. A common type of material trolley uses a single-wheel or two-wheel structure with a push handle at the rear. For easy loading, a support rod is often installed under the push handle or the trolley bucket. During loading, the support rod and wheels provide stable support for the material trolley, and the friction between the support rod and the ground prevents the vehicle from shifting. This type of trolley has a simple structure and is easy to use.

[0004] However, during unloading, workers usually push the handle upwards at an angle to tilt the trolley upwards around the center of the wheel so that the material can be poured out or removed. During this process, some material may remain in the hopper, requiring workers to come to the front of the hopper to clean it up. However, the support rod is of a fixed size and cannot support and fix the trolley in a tilted state. Workers also need to level the trolley before cleaning up the remaining material, or multiple people need to work together, with one person supporting the trolley and others assisting in cleaning up, which causes some inconvenience. Utility Model Content

[0005] This utility model provides a material trolley positioning and locking mechanism to solve the technical problems mentioned in the background art.

[0006] To solve the above problems, the present invention provides a high-efficiency dispersing device for fillers used in the production of thermally conductive rubber, which adopts the following technical solution: A material trolley positioning and locking mechanism includes a hopper, a push handle disposed at the rear of the hopper, and a wheel assembly disposed at the bottom of the hopper. A rod is rotatably connected to the bottom of the rear end of the hopper, and a sleeve rod is sleeved on the outer side of the rod. A pedal is rotatably connected to the bottom end of the sleeve rod. Several locking holes are opened on the side of the pedal. A storage groove is opened on the side of the rod. A locking block is disposed in the storage groove. An inclined surface is provided on the outer side of the locking block. A spring is disposed between the locking block and the storage groove.

[0007] The above technical solution works as follows: During unloading, the worker steps on the pedal and pushes the handle diagonally upwards. The trolley tilts upwards around the wheel center, and most of the material is poured out. Simultaneously, the insert rod rotates relative to the hopper, and the sleeve rod rotates relative to the pedal. The outer side of the locking block is compressed and moves into the receiving slot, while the insert rod is pulled out of the sleeve rod to match the movement of the hopper. When the hopper stops moving, the locking block is pushed out by a spring and locks into the corresponding locking hole. Then, the worker releases the handle, and the locking block locks the insert rod, preventing it from moving into the sleeve rod. The insert rod, sleeve rod, and pedal, along with the wheel assembly, provide support for the trolley, keeping it tilted. The worker can then clean the remaining material from the front of the hopper.

[0008] Furthermore, the insertion rod has a movable hole communicating with the storage slot, and a pull rope with its bottom end connected to the locking block is provided in the movable hole. The upper end of the pull rope is fastened to the push handle by a connecting buckle, and a pull ring is fixedly connected to the upper end of the pull rope.

[0009] Furthermore, each of the insert rods is equipped with a steering wheel at the turning point of the pull rope.

[0010] Furthermore, the bottom of the hopper is rotatably connected to two insert rods, and the two insert rods are respectively in the same plane as the two push handles.

[0011] Furthermore, a guide rod is fixedly connected inside the storage slot, and the locking block is sleeved on the outside of the guide rod.

[0012] Furthermore, the insertion rod is one and rotatably connected to the centerline of the hopper, and the wheel assembly adopts a two-wheel structure.

[0013] Furthermore, locking holes are provided on both the front and rear sides of the sleeve rod, and several locking holes are evenly arranged along the height direction of the sleeve rod.

[0014] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This material trolley positioning and locking mechanism, through the inclusion of a rod, sleeve, pedal, locking hole, collection slot, locking block, and spring, allows for efficient material unloading. During unloading, the operator steps on the pedal and pushes the handle upwards at an angle, causing the trolley to tilt upwards around the wheel's center, emptying most of the material. Simultaneously, the rod rotates relative to the hopper, and the sleeve rotates relative to the pedal. The outer side of the locking block is compressed and moves into the collection slot, while the rod is pulled out of the sleeve to accommodate the hopper's movement. Once the hopper stops moving, the locking block is pushed out by the spring and engages in the corresponding locking hole. The operator then releases the handle, and the locking block locks the rod, preventing it from moving further into the sleeve. The rod, sleeve, and pedal, along with the wheel assembly, support the trolley, maintaining its tilted position, allowing the operator to clean the remaining material from the front of the hopper. This eliminates the need to level the trolley before cleaning and reduces the need for multiple operators, making unloading much more convenient.

[0015] 2. The material trolley positioning and locking mechanism features a movable hole, pull rope, and pull ring. The movable hole provides installation space for the pull rope, which connects to the locking block and is attached to the push handle at its upper end. After unloading, the operator can pull the pull ring while holding the push handle. The pull ring moves the pull rope, which in turn pulls the locking block into the receiving slot, thus unlocking the insertion rod. The operator can then rotate the push handle in the opposite direction to level the trolley and release the pull ring. The locking block, under the action of the spring, re-enters the locking hole, securing the insertion rod. The operator can control the locking mechanism directly from the push handle, making it more convenient to use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] like Figures 1 to 4As shown, this utility model includes a hopper 1, a push handle 2 located at the rear of the hopper 1, and a wheel assembly 3 located at the bottom of the hopper 1. A plug rod 4 is rotatably connected to the bottom of the rear end of the hopper 1. A sleeve rod 5 is sleeved on the outer side of the plug rod 4. A pedal 6 is rotatably connected to the bottom end of the sleeve rod 5. Several locking holes 7 are opened on the side of the pedal 6. A storage groove 8 is opened on the side of the plug rod 4. A locking block 9 is provided in the storage groove 8. An inclined surface is provided on the outer side of the locking block 9. A spring 10 is provided between the locking block 9 and the storage groove 8.

[0020] The working principle of this utility model is as follows: S1. During loading, the insert rod 4, sleeve rod 5 and pedal 6, together with the wheel assembly 3, provide stable support for the material trolley. The friction between the pedal 6 and the ground prevents the vehicle from shifting, and the staff can carry out the loading work. S2. After loading is complete, the worker holds the push handle 2 and pushes the trolley to its destination. During unloading, the worker steps on the pedal 6 and pushes the push handle 2 diagonally upwards. The trolley tilts upwards around the wheel center, and most of the material is poured out. Simultaneously, the insert rod 4 rotates relative to the hopper 1, and the sleeve rod 5 rotates relative to the pedal 6. The outer side of the locking block 9 is compressed and moves into the receiving slot 8. The insert rod 4 is pulled out from the sleeve rod 5 to match the movement of the hopper 1. When the hopper 1 stops moving, the locking block 9 is pushed out by the spring 10 and locked into the corresponding locking hole 7. S3. When the worker releases the push handle 2, the locking block 9 locks the insert rod 4 to prevent it from moving into the sleeve rod 5. The insert rod 4, sleeve rod 5 and pedal 6, together with the wheel assembly 3, form a support for the trolley, keeping it in an inclined state. The worker can then clean the remaining material in the hopper 1 from the front.

[0021] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0022] Embodiment 1 of the material trolley positioning and locking mechanism provided by this utility model: A movable hole 11 communicating with a storage groove 8 is provided inside the insertion rod 4. A pull rope 12, the bottom end of which is connected to a locking block 9, is provided inside the movable hole 11. The upper end of the pull rope 12 is fastened to the push handle 2 via a connecting buckle. A pull ring 14 is fixedly connected to the upper end of the pull rope 12. Steering wheels 13 are provided inside the insertion rod 4 at the turning points of the pull rope 12. Two insertion rods 4 are rotatably connected to the bottom of the hopper 4, and the two insertion rods 4 are respectively on the same plane as the two push handles 2. A guide rod 15 is fixedly connected inside the storage groove 8, and the locking block 9 is sleeved on the outside of the guide rod 15.

[0023] In this embodiment, the movable hole 11 provides installation space for the pull rope 12. The pull rope 12 is connected to the locking block 9, and its upper end is attached to the push handle 2. After unloading, the operator can pull the pull ring 14 while holding the push handle 2. The pull ring 14 drives the pull rope 12 to move, and the pull rope 12 pulls the locking block 9 into the storage slot 8, thus unlocking the insertion rod 4. The operator can then rotate the push handle 2 in the opposite direction to level the trolley and release the pull ring 14. Under the action of the spring 10, the locking block 9 re-enters the locking hole 7 to fix the insertion rod 4.

[0024] A guide rod 15 is installed inside the storage slot 8. The guide rod 15 can constrain the locking block 9 to prevent it from displacing in other directions.

[0025] It should be noted that the pull rope 12 should be made of a material with sufficient durability, such as steel strand, to ensure the lifespan of the corresponding mechanism.

[0026] Embodiment 2 of the material trolley positioning and locking mechanism provided by this utility model: There is one insertion rod 4 which is rotatably connected to the center line of the hopper 1, and the wheel assembly 3 adopts a two-wheel structure. Locking holes 7 are provided on both the front and rear sides of the sleeve rod 5, and a number of locking holes 7 are evenly arranged along the height direction of the sleeve rod 5.

[0027] Its main difference from Example 1 is: In Example 1, there are two insertion rods 4, and two sets of locking mechanisms consisting of the corresponding insertion rods 4, sleeve rods 5, and pedals 6 are respectively set on the hopper 1 at the positions corresponding to the push handle 2.

[0028] In this embodiment, there is one insertion rod 4, and a corresponding locking mechanism consisting of the insertion rod 4, sleeve rod 5, and pedal 6 is provided, and is located at the centerline of the hopper 1. This design creates a triangular support structure between the locking mechanism and the wheel assembly, ensuring the stability of the hopper 1. Furthermore, reducing the number of locking mechanisms lowers the overall cost of the trolley.

[0029] Additionally, it should be noted that in this example, when configuring the pull rope 12, multiple clips or other tools should be used to secure it to the hopper 1 and push handle 2, so that it is attached to the hopper 1 and push handle 2 to prevent it from becoming loose and affecting its use.

[0030] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0031] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
