Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic barrel transportation technology, specifically to an anti-tipping device for stacking plastic barrels. Background Technology
[0002] Plastic drums are widely used for the storage and transportation of various liquids. They have excellent properties for packaging special hazardous materials and are often used for packaging hazardous materials that require heat preservation, moisture protection, pressure resistance, and corrosion resistance. During the transportation of plastic drums, in order to improve the transportation efficiency, multiple plastic drums usually need to be stacked together and fixed and limited by anti-tipping devices.
[0003] However, current anti-tipping devices typically involve placing stacked plastic buckets in a seat groove or securing them with ropes, making it difficult to support and secure the sides of the stacked plastic buckets. When traveling on bumpy roads during transportation, the stability of the stacked plastic buckets is poor, making them prone to tipping over and damaging the plastic buckets. This increases the defect rate of plastic bucket transportation and raises transportation costs. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-tipping device for stacked plastic buckets. Through the structural design of bidirectional screws, support rods and fasteners, the sides of the stacked buckets can be easily supported and fixed, which improves the stability of the stacked buckets during transportation and solves the problem of difficulty in supporting and fixing the sides of stacked plastic buckets.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is an anti-tipping device for stacking plastic buckets, including a base plate with a rectangular groove. A bidirectional screw is rotatably installed in the rectangular groove. Two drive blocks are fitted on the outer surface of the bidirectional screw. The drive blocks cooperate with the rectangular groove. Each drive block is provided with a movable plate. A pair of support rods are rotatably installed on each of the two movable plates. The top ends of the two pairs of support rods are rotatably connected to a fixing member.
[0007] Furthermore, two circular grooves are formed in the rectangular groove, and a bearing is fitted in the circular groove. The two ends of the bidirectional screw are respectively fitted with the inner rings of the two bearings. One end of the bidirectional screw passes through the circular groove to the outside of the base plate, and a turntable is provided at one end of the bidirectional screw.
[0008] Furthermore, two guide grooves are provided on the base plate, and the bottom ends of the movable plate respectively cooperate with the two guide grooves.
[0009] Furthermore, the fasteners include clamp one and clamp two. Clamp one has threaded rods rotatably mounted on both ends, and clamp two has threaded holes on both ends. The outer surface of one end of the threaded rod mates with the threaded hole.
[0010] Furthermore, both ends of clamp one are provided with circular groove two, and bearing two is fitted inside circular groove two. The other end of the threaded rod is fitted with the inner ring of bearing two. Both ends of clamp one are provided with two limiting rods, and both ends of clamp two are provided with two limiting holes. The outer surface of one end of the limiting rod is fitted with the limiting hole. The inner surfaces of clamp one and clamp two are provided with anti-slip rubber pads.
[0011] Furthermore, a mounting base is provided on the base plate, and a placement groove is provided on the mounting base. A stacking barrel is placed in the placement groove. Clamp one and clamp two are symmetrically arranged with the vertical center line of the mounting base as the center, and the stacking barrel is located between clamp one and clamp two.
[0012] This utility model has the following beneficial effects:
[0013] 1. This utility model, through the structural design of bidirectional screws, support rods, and fasteners, uses clamps one and two to stably limit and fix the sides of the stacked buckets, and then uses four inclined support rods to support the sides of the stacked buckets, thereby achieving stable support and fixation of the stacked buckets. This allows for convenient support and fixation of the sides of the stacked buckets, effectively improving the stability of the stacked buckets during transportation, preventing the stacked buckets from tipping over and being damaged during transportation, reducing the defect rate of plastic bucket transportation, and greatly reducing transportation costs.
[0014] 2. This utility model has a clever structure and simple design. By rotating the two threaded rods, clamp one and clamp two are brought closer to each other, so that the inner surfaces of clamp one and clamp two are tightly fitted with the outer edge surface of the stacked barrel. This achieves the fixed positioning of stacked barrels of different specifications and sizes, thus conveniently supporting and fixing stacked barrels of different specifications and sizes, enriching the application range of the device and improving its practicality.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: an anti-tipping device for stacking plastic buckets, including a base plate 1, a rectangular groove 101 on the base plate 1, a bidirectional screw 2 rotatably installed in the rectangular groove 101, two circular grooves 1 are opened in the rectangular groove 101, and a bearing 1 is fitted in the circular groove 1. The two ends of the bidirectional screw 2 are respectively engaged with the inner rings of the two bearings, which can ensure the rotation effect of the bidirectional screw 2 in the rectangular groove 101. One end of the bidirectional screw 2 passes through the circular groove to the outside of the base plate 1, and a turntable is provided at one end of the bidirectional screw 2 to facilitate the rotation of the bidirectional screw 2.
[0023] Two drive blocks 201 are fitted on the outer surface of the bidirectional screw 2. The drive blocks 201 are fitted with rectangular grooves 101. Each drive block 201 is equipped with a movable plate 202. Two guide grooves 102 are opened on the base plate 1. The bottom ends of the movable plates 202 are respectively fitted with the two guide grooves 102, which can ensure the stability of the two movable plates 202 moving towards each other on the base plate 1. A pair of support rods 3 are rotatably installed on each of the two movable plates 202. The top ends of the two pairs of support rods 3 are rotatably connected to the fixing parts 4. A pair of U-shaped frames 1 are provided on each of the two movable plates 202. The bottom ends of the support rods 3 are rotatably fitted on the U-shaped frames 1. A pair of U-shaped frames 2 are provided on the outer surface of clamp 1 401 and clamp 2 402. The top ends of the support rods 3 are rotatably fitted on the U-shaped frames 2, which can facilitate the support of the stacked buckets 5 and ensure the support effect of the four support rods 3 on the stacked buckets 5.
[0024] In use, a certain number of plastic buckets are stacked sequentially in the placement slot on the mounting base 103 to form a stacking bucket 5. Then, according to the thickness of the outer edge of the stacking bucket 5, the space between clamp 1 401 and clamp 2 402 is adjusted to be close to the thickness of the outer edge of the stacking bucket 5. Then, the double-acting screw 2 is rotated by the turntable, so that the double-acting screw 2 rotates in the rectangular slot 101, so that the two driving blocks 201 move towards each other in the rectangular slot 101, thereby driving the two movable plates 202 to move closer to each other on the base plate 1. The two movable plates 202 lift the fixing part 4 vertically upward through the corresponding pair of support rods 3. After the fixing part 4 is moved up to the outer edge of the stacking bucket 5, the distance between clamp 1 401 and clamp 2 402 is reduced by the two threaded rods 4011, so that clamp 1 401 and clamp 2 402 stably limit and fix the side of the stacking bucket 5. Then, the side of the stacking bucket 5 is supported by four inclined support rods 3, thereby achieving stable support and fixation of the stacking bucket 5.
[0025] The fastener 4 includes clamp one 401 and clamp two 402. Clamp one 401 has threaded rods 4011 rotatably mounted at both ends. Clamp two 402 has threaded holes 4021 at both ends. One end of the threaded rod 4011 mates with the threaded hole 4021. Both ends of clamp one 401 have circular grooves 2, within which bearings 2 are fitted. The other end of the threaded rod 4011 mates with the inner ring of the bearing 2. This ensures the rotation of the threaded rod 4011 at the end of clamp one 401, allowing adjustment of the distance between clamp one 401 and clamp two 402. Clamp one 401 has two limiting rods 4012 at both ends, and clamp two locating holes 4022 at both ends. One end of the limiting rod 4012 mates with the locating hole. The 4022 combination improves stability when adjusting the distance between clamp 1 401 and clamp 2 402. The inner surfaces of clamp 1 401 and clamp 2 402 are provided with anti-slip rubber pads to ensure that the inner surfaces of clamp 1 401 and clamp 2 402 are stably attached to the outer surface of the stacking barrel 5, thus improving the fixing effect of the stacking barrel 5. The base plate 1 is provided with a mounting seat 103, and the mounting seat 103 has a placement groove. The stacking barrel 5 is placed in the placement groove to ensure that the stacking barrel 5 is stacked stably. Clamp 1 401 and clamp 2 402 are symmetrically arranged with the vertical center line of the mounting seat 103 as the center. The stacking barrel 5 is located between clamp 1 401 and clamp 2 402, which can facilitate the fixing of the stacking barrel 5 by clamp 1 401 and clamp 2 402.
[0026] When it is necessary to support and fix stacked barrels 5 with different outer edge thicknesses, firstly, rotate the two threaded rods 4011 on clamp one 401 simultaneously to adjust the distance between clamp one 401 and clamp two 402 to be slightly larger than the outer edge thickness of the stacked barrel 5 to be fixed. Then, by rotating the bidirectional screw 2, the four support rods 3 drive the fixing part 4 to move upward to the outer edge of the stacked barrel 5. Then, tighten the two threaded rods 4011 simultaneously. Under the action of the interaction force, clamp one 401 and clamp two 402 move closer to each other. During the process of clamp one 401 and clamp two 402 moving closer to each other, clamp one 401 and clamp two 402 rotate and move slightly downward with the corresponding two support rods 3, so that the inner surface of clamp one 401 and clamp two 402 fits tightly with the outer edge surface of the stacked barrel 5, thereby achieving the fixing and limiting of stacked barrels 5 of different specifications and sizes.
[0027] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
