Description

Technical Field

[0001] This utility model relates to the field of leather technology, and in particular to an elastic traction connection device for transporting raw hides. Background Technology

[0002] In the leather production process, leather blanks need to be transported to multiple work sections for different processing operations. Flatbed carts are the most frequently used tool, and when fully loaded with leather blanks, it requires 3-4 people working together to push them. Furthermore, the casters at the front of the flatbed cart can easily cause foot injuries when workers push off, posing a safety hazard. Therefore, we use tricycles to pull the flatbed carts for transportation, requiring the design of a connection device. Existing connection methods mostly use rigid connections, such as simple iron hooks or rigid connecting rods. This connection method has significant drawbacks: during transportation, when the tricycle starts, brakes, or travels over bumpy roads, a huge rigid impact force is generated due to the lack of cushioning between the two vehicles. This not only makes the connection device prone to deformation or damage but may also cause goods to fall off the flatbed cart, affecting production progress and product quality. Therefore, there is an urgent need for a traction device that can effectively cushion impacts and improve connection reliability and safety. Utility Model Content

[0003] To solve the above problems, this utility model provides an elastic traction connection device for transporting hides.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an elastic traction connecting device for transporting raw hides, including a front vertical iron plate and a rear vertical iron plate. A left through hole is opened in the middle of the front vertical iron plate, and a right through hole is opened in the middle of the rear vertical iron plate. Wear-resistant bushings are welded into both the left and right through holes. A pin hole is provided at one end of the connecting rod, and the connecting rod is inserted into the two wear-resistant bushings. Springs, spring caps, and limit nuts are mirror-installed on both sides of the connecting rod. A left square iron pipe and a right square iron pipe are welded to the sides of the front vertical iron plate and the rear vertical iron plate, respectively. Iron hooks are provided at the ends of the left square iron pipe and the right square iron pipe.

[0005] Furthermore, the front vertical iron plate and the rear vertical iron plate are arranged parallel to each other and spaced apart.

[0006] Furthermore, both the front and rear vertical iron plates are rectangular plate structures.

[0007] Furthermore, the left through hole and the right through hole are coaxial.

[0008] Furthermore, the pin hole is hinged to the rear frame of the tricycle via a pin.

[0009] Furthermore, the limit nut is threadedly connected to the connecting rod.

[0010] Furthermore, one spring has its left side pressed against the spring cover and its right side pressed against the front vertical iron plate; the other spring has its left side pressed against the rear vertical iron plate and its right side pressed against the spring cover.

[0011] Furthermore, the spring cap is a round, thick iron sheet that fits over the left and right ends of the connecting rod through the central hole and is secured with a limit nut.

[0012] Furthermore, the iron hook is connected to the flatbed truck.

[0013] The beneficial effects of this utility model are: 1. Excellent buffering and shock absorption performance: By setting springs on both sides of the connecting rod, a highly efficient elastic buffer system is formed; when the tricycle starts, brakes or bumps, the springs can effectively absorb and release the impact energy generated between the two vehicles, converting rigid impact into flexible relative motion, which greatly reduces the impact force on the connecting device and the cargo. 2. Protect vehicles and cargo: The cushioning effect avoids the hard pulling and squeezing of the connecting device, extending the service life of the device itself; at the same time, the smooth traction can effectively prevent cargo from shifting or falling due to violent shaking. 3. Simple structure and low cost: The entire device is mainly composed of common metal plates, round rods, springs and standard parts, with a simple structure and low manufacturing process requirements; 4. Reliable connection and easy to use: The left end is securely hinged to the tricycle via a pin, and the right end is hooked to the flatbed truck via an iron hook. The assembly and disassembly process is simple and quick, making it very suitable for transportation scenarios that require frequent attachment and detachment. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] An elastic traction connection device for transporting hides includes a front vertical iron plate 13 and a rear vertical iron plate 14. Both the front vertical iron plate 13 and the rear vertical iron plate 14 are rectangular plate structures. The front vertical iron plate 13 and the rear vertical iron plate 14 are parallel and spaced apart. A left through hole 15 is opened in the middle of the front vertical iron plate 13, and a right through hole 16 is opened in the middle of the rear vertical iron plate 14. The left through hole 15 and the right through hole 16 are coaxial. Wear-resistant bushings 18 are welded into both the left through hole 15 and the right through hole 16. A connecting rod 2 has a pin hole 21 at one end, and the connecting rod 2 is inserted into the two wear-resistant bushings 18. Both sides of the connecting rod 2 are mirror-shaped. The system includes springs 3, spring covers 4, and limiting nuts 5. One spring 3 rests on the spring cover 4 on its left side and on the front vertical iron plate 13 on its right side. Another spring 3 rests on the rear vertical iron plate 14 on its left side and on the spring cover 4 on its right side. The spring cover 4 is a round, thick iron sheet that fits over the left and right ends of the connecting rod 2 through a central hole and is secured with limiting nuts 5, which are threaded onto the connecting rod 2. A left square iron pipe 11 and a right square iron pipe 12 are welded to the sides of the front vertical iron plate 13 and the rear vertical iron plate 14, respectively. The ends of the left square iron pipe 11 and the right square iron pipe 12 are equipped with iron hooks 17. The pin hole 21 is hinged to the rear frame of the tricycle via a pin 6, and the iron hooks 17 are connected to the flatbed.

[0018] In use, the pin hole 21 at the left end of the connecting rod 2 is hinged to the rear frame of the tricycle via the pin 6. Then, the iron hook 17 is hooked onto the bottom frame of the flatbed. When the tricycle moves and generates impacts in the front and rear directions (such as starting or braking), this application will generate a tendency for relative motion. This tendency will compress one of the springs 3, and the impact energy will be absorbed by the spring 3, thereby achieving buffering. When turning, the connecting rod 2 is restricted by the front vertical iron plate 13 and the rear vertical iron plate 14, causing the flatbed to turn. When passing over bumpy roads and generating up-and-down vibrations, this application allows for a certain angle of swing.
