Description

Technical Field

[0001] This utility model relates to the field of conveyor belts, specifically to a belt interface connection device for conveyor belts. Background Technology

[0002] To transport materials in bulk, people usually use conveyor belts for auxiliary transport. The length of the conveyor belt is selected according to the needs. After the length of the conveyor belt is selected, the beginning and end of the conveyor belt are spliced ​​together using the corresponding conveyor belt interface connection device.

[0003] Existing conveyor belt interface connection devices are divided into conveyor belt cold bonding joint method, conveyor belt hot vulcanization joint method, belt buckle joint method and rubber clamp joint method. Among them, the belt buckle joint method is favored by conveyor belts of different lengths that need to be frequently connected due to its detachable characteristics. At present, belt buckle assemblies are divided into interlocking male buckles and female buckles. The connection ends of the male buckles and female buckles are usually hollow structures. The connection between the two is fixed by a pin that passes through the hollow ring of the connection end of the male buckle and female buckle. The beginning and end of the conveyor belt are composed of U-shaped buckles with multiple anti-slip nails on the bottom surface, which makes them like belt buckles and can be freely disassembled.

[0004] While this connection method ensures that the connection length of the conveyor belt can be freely adjusted, the belt buckle is mainly fixed by a pin. If excessive force is applied during use, it can easily cause fatigue of the pin, leading to breakage or deformation. This can result in the belt buckle assembly breaking or becoming difficult to disassemble during use. Utility Model Content

[0005] The technical problem this invention aims to solve is that the stability of the belt buckle assembly in the existing conveyor belt interface connection device depends on the quality of the pin. Once the pin malfunctions, the belt buckle assembly will fail and be difficult to repair.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a belt interface connection device for a conveyor belt, including a conveyor belt to be connected at both ends and a belt buckle assembly for connecting the beginning and end ends of the conveyor belt.

[0007] The belt buckle assembly includes a male buckle and a female buckle that are interlocked with each other. A pin is provided on one side of the connection end of the male buckle and the female buckle, passing through the connection end of the male buckle and the female buckle. The tail ends of the male buckle and the female buckle are provided with U-shaped buckles to fix the beginning and end of the conveyor belt. Several anti-slip nails are welded on the bottom surface of the U-shaped buckle and pass through the top surface of the U-shaped buckle.

[0008] The connection end of the female buckle and the connection end of the female buckle are two L-shaped planes that fit together. The bottom surface of the connection end of the female buckle is provided with several U-shaped buckles that pass through the top surface of the connection end of the female buckle. The pin passes through the vertical end of the U-shaped buckle and the groove sidewall inside the connection end of the female buckle. An inverted U-shaped spring sheet is welded to one side of the groove inside the connection end of the female buckle to prevent the U-shaped buckle from rebounding.

[0009] As an improvement, an anti-slip screw is welded to one side of the pin rod, passing through the side wall of the female buckle connection end, and the through hole of the anti-slip screw on the side wall of the female buckle connection end is a countersunk hole.

[0010] As an improvement, the top surface of the U-shaped buckle is provided with a rectangular groove, and the bottom surface of the U-shaped buckle is provided with a nut post located below the rectangular groove. The nut post is provided with an anti-loosening screw that passes through the rectangular groove. The U-shaped buckle is made of a highly elastic sheet material.

[0011] As an improvement, the conveyor belt is provided with through holes at both ends corresponding to the nut post and the anti-slip nail.

[0012] As an improvement, the bottom surface of the U-shaped buckle and the bottom surface of the thick column end of the L-shaped plane are welded together to form an integrated structure.

[0013] As an improvement, the bottom surface of the U-shaped buckle is inclined, and the groove inside the female buckle connection end is a C-shaped structure.

[0014] The advantages of this invention compared to existing technologies are as follows: Based on the traditional pin-rod fixed connection, this device designs the connection end of the male and female buckles as a buckle structure that engages through a U-shaped buckle and an I-shaped groove. In order to ensure that the U-shaped buckle will not fall off due to vibration during the connection process, an inverted U-shaped spring sheet is welded to the vertical end of the U-shaped buckle in the I-shaped groove, thereby pressing the U-shaped buckle tightly against the side opening of the I-shaped groove, reducing the force area of ​​the pin and increasing the overall stability of the belt buckle assembly.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] As per the instruction manual Figure 1 , 2 As shown in Figure 3, the conveyor belt 1 includes the beginning and end ends to be connected, and the belt buckle assembly 2 connecting the beginning and end ends of the conveyor belt 1. The belt buckle assembly 2 includes a male buckle 21 and a female buckle 22 that are interlocked with each other. A pin 23 is provided on one side of the connection end of the male buckle 21 and the female buckle 22, which passes through the connection end of the male buckle 21 and the female buckle 22, so that the connection end of the male buckle 21 and the female buckle 22 are connected in series by the pin 23, thereby completing the connection of the conveyor belt 1.

[0023] To ensure the stability of the connection between the male buckle 21 and the female buckle 22 and the beginning and end of the conveyor belt 1, the end of both the male buckle 21 and the female buckle 22 is provided with a U-shaped buckle 24 to fix the beginning and end of the conveyor belt 1. The U-shaped buckle 24 is made of a highly elastic sheet material. Several anti-slip nails 241 are welded to the bottom surface of the U-shaped buckle 24 and pass through the top surface of the U-shaped buckle 24. A rectangular groove 242 is provided on the top surface of the U-shaped buckle 24, and a nut post 243 is provided on the bottom surface of the U-shaped buckle 24 below the rectangular groove 242. The nut post 243 has an anti-loosening screw that passes through the rectangular groove 242 inside. 244, wherein the beginning and end ends of the conveyor belt 1 are provided with through holes corresponding to the nut post 243 and the anti-slip nail 241. In use, simply pass the nut post 243 and the anti-slip nail 241 through the through holes at the beginning and end ends of the conveyor belt 1, then pass the anti-loosening screw 244 through the rectangular slide groove 242, and screw the anti-loosening screw 244 into the nut post 243 below. By turning the anti-loosening screw 244, the top surface of the U-shaped buckle 24 presses against the top of the conveyor belt 1, and the anti-slip nail 241 is inserted into the anti-slip nail 241 through hole on the top surface of the U-shaped buckle 24, thereby preventing the connection of the conveyor belt 1 from becoming loose.

[0024] As per the instruction manual Figure 3 , 4As shown in Figure 5, the connecting end of the female buckle 22 and the connecting end of the male buckle 21 are two L-shaped planes that fit together. The bottom surface of the connecting end of the male buckle 21 has several U-shaped buckles 211 that pass through the top surface of the connecting end of the female buckle 22. To ensure the stability of the connection between the U-shaped buckle 24 and the L-shaped plane, the bottom surface of the U-shaped buckle 24 and the bottom surface of the thick column end of the L-shaped plane are welded together to form an integrated structure. To facilitate the rapid sliding of the U-shaped buckles 211 when the male buckle 21 is pressed down, the bottom surface of the U-shaped buckles 211 is inclined, and the groove inside the connecting end of the female buckle 22 has a U-shaped structure. To prevent the U-shaped buckle 211 from loosening during use, an inverted U-shaped spring piece 221 is welded to one side of the groove inside the connecting end of the female buckle 22 to prevent the U-shaped buckle 211 from rebounding. The inverted U-shaped spring piece 221 is located on one side of the vertical end of the U-shaped buckle 211. Through the elasticity of the inverted U-shaped spring piece 221, it can be ensured that the U-shaped buckle 211 will not slip out of the U-shaped groove during use. In order to strengthen the connection between the U-shaped buckle 211 and the U-shaped groove, the pin 23 passes through the vertical end of the U-shaped buckle 211 and the side wall of the groove inside the connecting end of the female buckle 22.

[0025] To prevent the pin 23 from slipping out of the pin hole in the U-shaped buckle 211 and the side wall of the C-shaped groove during use, an anti-slip screw 231 is welded to one side of the pin 23, passing through the side wall of the connecting end of the female buckle 22. The through hole of the anti-slip screw 231 in the side wall of the connecting end of the female buckle 22 is a countersunk hole, thereby avoiding the situation where the anti-slip screw 231 rubs against the support frame of the conveyor belt 1 during use.

[0026] In specific implementation of this utility model, the U-shaped buckle 211 below the female buckle 21 is slid into the C-shaped groove of the female buckle 22. Under the action of the inverted U-shaped spring plate 221, the U-shaped buckle 211 will press tightly against the side wall of the C-shaped groove. While pressing tightly, the pin hole on the side wall of the U-shaped buckle 211 will be aligned with the pin hole on the side of the C-shaped groove. Then, the pin 23 is passed through the countersunk hole. Then, the anti-loosening screw 244 at the end of the pin 23 is screwed into the screw hole on the side of the C-shaped groove for fixing. The bottom length of the pin 23 will not exceed the bottom surface of the pin on the opposite side of the countersunk hole. When disassembling, simply remove the pin 23 and press the end of the female buckle 22 to remove the female buckle 21.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
