Description

Technical Field

[0001] This utility model relates to a connecting buckle; in particular, it refers to a connecting buckle with a cap on a pivot assembly. Background Technology

[0002] Existing connecting rings include a ring body with an opening. The ring body has a buckle head and a pivot portion at the upper and lower ends of the opening, respectively. The pivot portion has a shaft hole, and the lower end of a gate rod is fitted onto the pivot portion. The gate rod has a pair of pivot holes communicating with the shaft hole. A rivet through the shaft hole is riveted into the pair of pivot holes, allowing the gate rod to rotate relative to the ring body. The upper end of the gate rod has a buckle head groove for engaging with the buckle head. Some connecting rings are designed with a spring connecting the gate rod and the pivot portion to automatically reset the gate rod that has disengaged from the buckle head. Other connecting rings have an outer tube fitted around the circumference of the gate rod. By rotating the outer tube to cover or open the front side of the buckle head groove, the fixing and releasing of the gate rod can be controlled.

[0003] However, in existing connecting rings, after the rivets are installed, the rivet heads protrude from the outer surface of the gate arm. Therefore, during use, the rivet heads are easily damaged by impacts from other objects, affecting the stability of the rivet's pivoting function. Furthermore, when the rivet head is exposed to a conductive environment, it may pose a safety hazard due to conductivity, especially in high-voltage electrical work or applications requiring high levels of protection. The lack of insulation design on the rivet head makes it impossible to avoid conductivity, leading to problems such as poor insulation or rivet loosening, thus affecting the overall reliability and safety of the connecting ring. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a connecting buckle with a cap for a pivot assembly. By covering the head of the rivet with a cap, the head of the rivet is protected from being exposed and the head is provided with insulation. This can avoid the safety hazards caused by damage to the head due to external impact or poor insulation, thereby improving the durability and safety of the pivot assembly.

[0005] To achieve the above objectives, this utility model provides a connecting buckle with a cap for a pivot assembly, including a buckle body, a gate rod body, and a pivot assembly.

[0006] The buckle body is a C-shaped ring with an opening in the middle of its front side. The buckle body has a pivot portion and a buckle head adjacent to the lower and upper ends of the opening, respectively. The pivot portion has an insert plate with a shaft hole. The lower end of the gate rod has a groove with an opening at the bottom, extending through both the front and rear sides of the lower end of the gate rod. Two pivot holes are formed on the left and right sides of the lower end of the gate rod, communicating with the groove. The groove accommodates the insert plate, and the two pivot holes communicate with both ends of the shaft hole. The upper end of the gate rod is fastened to the buckle head, closing the opening. The pivot assembly includes a rivet and a cap; the rivet has a connected shaft and a head, the shaft passes through the two pivot holes and the shaft hole, the head is integrally connected to one end of the shaft, and the other end of the shaft forms a riveting portion; the head abuts against the outer edge of one of the two pivot holes, and the head protrudes from the outer surface of the lower end of the buckle body, the riveting portion abuts against the outer edge of the other pivot hole, and the cap is an insulating cover that fits tightly onto the head.

[0007] The advantage of this invention is that by fitting the cap onto the head of the rivet, the head protruding from the buckle body is protected by the cap, preventing the rivet head from being exposed and providing insulation. This avoids damage to the head of the pivot assembly from external impacts and prevents poor insulation of the pivot assembly due to exposed head, thus improving the durability and safety of the pivot assembly used for pivoting the gate rod.

[0065] The gate stem 20 includes a gate stem body 22 and a gate stem insulation layer 24. A downward-opening groove 221 is provided at the lower end of the gate stem body 22, extending through both the front and rear sides of the lower end of the gate stem body 22. Two pivot holes 222 are formed on the left and right sides of the lower end of the gate stem body 22. The groove 221 accommodates the insert plate 161 of the pivot part 16, and the two pivot holes 222 communicate with the left and right sides of the shaft hole 162.

[0066] The upper end of the gate rod 22 has a buckle groove 223 with its opening facing forward. The front and upper sides of the buckle groove 223 form a sleeve opening 224 and a through opening 225, respectively. The upper end of the sleeve opening 224 is connected to the front end of the through opening 225. The buckle groove 223 and the left and right parts of the through opening 225 form a pair of hooks 226. A lower convex ring 227 is formed on the outer peripheral surface of the gate rod 22 above the groove 221, and an upper convex ring 228 is formed on the outer peripheral surface of the gate rod 22 below the buckle groove 223. The lower convex ring 227 and the upper convex ring 228 are spaced apart vertically. The portion of the gate rod 22 between the lower convex ring 227 and the upper convex ring 228 forms a waist 229. The waist 229 is located on the middle outer peripheral surface of the gate rod 22, and the front side of the waist 229 has a spring insertion hole 2291.

[0067] The gate stem insulation layer 24 includes a first insulation layer 241 and a second insulation layer 242. The first insulation layer 241 is injection-molded onto the outer surface of the lower end of the gate stem body 22. A first annular groove 21 is formed between the upper edge of the first insulation layer 241 and the lower convex ring 227. The second insulation layer 242 is injection-molded onto the outer surface of the upper end of the gate stem body 22. A second annular groove 23 is formed between the lower edge of the second insulation layer 242 and the upper convex ring 228. The upper edge of the first insulation layer 241 and the lower edge of the second insulation layer 242 are spaced apart and therefore not connected. The buckle groove 223 is fastened forward to the buckle 18 of the buckle body 10. The hook portion 226 of the buckle groove 223 is inserted into the groove 181 of the buckle 18. The fixing hook 182 is embedded in the buckle groove 223 and is located below the hook portion 226, so that the gate rod 20 closes the opening 14 of the buckle body 10.

[0068] Please refer to Figure 2 and Figures 5 to 7 As shown, the pivot assembly 30 includes a rivet 32, a cap 34, and an end cap 36. The rivet 32 ​​has a connected shaft 321 and a head 322. The shaft 321 passes through the two pivot holes 222 and the shaft hole 162. One end of the shaft 321 is connected to the head 322, and the other end of the shaft 321 forms a riveting portion 323. The diameter of the head 322 is greater than the diameter of the shaft 321, and the diameter of the riveting portion 323 is greater than the diameter of the shaft 321.

[0069] The head 322 is a conical block that is wider at the outside and narrower at the inside. The inner end of the head 322 abuts against the outer edge of one of the two pivot holes 222, so that the head 322 protrudes from the outer surface of the lower end of the gate rod 20, that is, from the outer surface of the first insulating layer 241. The riveting part 323 abuts against the outer edge of the other pivot hole 222. The middle of the shaft 321 pivotally passes through the shaft hole 162, so that the lower end of the gate rod 20 is pivotally connected to the pivot part 16 of the buckle body 10, allowing the gate rod 20 to swing back and forth with the rivet 32 ​​as the rotation center. The cap 34 is a flexible insulating cover made of plastic or rubber and fits onto the head 322. The inner circumferential surface of the cap 34 contacts the outer circumferential surface of the head 322. A clamping opening 341 is formed on the side of the cap 34 near the shaft 321. The width of the clamping opening 341 is smaller than the maximum width of the internal space of the cap 34, so that the cap 34 fits tightly onto the head 322. The end cap 36 is a flexible insulating cover made of plastic or rubber and fits onto the riveting part 323, preventing the riveting part 323 from being exposed.

[0070] Please refer to Figures 2 to 5 As shown, the outer tube 40 is a vertically arranged tube, and its outer surface has an outer tube insulation layer 41. The outer tube 40 is fitted around the gate rod body 20. A first washer 42 is embedded in the first annular groove 21. The first washer 42 is a C-shaped ring, and its outer surface protrudes from the outer surface of the first insulation layer 241. A second washer 44 is embedded in the second annular groove 23. The second washer 44 is a C-shaped ring, and its outer surface protrudes from the outer surface of the second insulation layer 242. The inner circumferential surface of the outer tube 40 slidably abuts against the outer surfaces of the first washer 42 and the second washer 44, allowing the outer tube 40 to rotate relative to the gate rod body 20.

[0071] The front side of the upper end of the outer tube 40 covers the sleeve opening 224 of the buckle groove 223 of the gate rod body 20. An opening recess 46 with an upper opening is formed at the upper end of the outer tube 40. The shape of the opening recess 46 is slightly larger than the shape of the sleeve opening 224 of the buckle groove 223. The opening recess 46 is oriented relative to the buckle groove 223; in this preferred embodiment, the opening recess 46 faces to the right. An inwardly opening long groove 461 is formed on the bottom side of the opening recess 46. The long groove 461 is an elongated groove extending in the vertical direction with a closed lower end, and its upper end communicates with the opening recess 46.

[0072] A spiral spring 47 is fitted onto the waist 229 of the gate rod body 20. One end of the spiral spring 47 is inserted into the spring insertion hole 2291 of the waist 229, and the other end of the spiral spring 47 is inserted into the long groove 461 of the outer tube 40. The restoring force provided by the spiral spring 47 causes the opening notch 46 of the outer tube 40 to be rotated to a position facing forward and directly opposite the sleeve opening 224 of the buckle groove 223. After release, it can be driven back to its original position by the spiral spring 47. The bottom edge of the outer tube 40 is recessed to form an arc-shaped notch 48. The arc-shaped notch 48 has a stop surface 481 on each side corresponding to the clockwise and counterclockwise directions when viewed from above. The arc-shaped notch 48 accommodates the cap 34 of the pivot assembly 30 and the head 322 fitted by the cap 34. One of the two stop surfaces 481 abuts against or is adjacent to the cap 34. In this preferred embodiment, the stop surface 481 facing the counterclockwise direction abuts against the cap 34 when viewed from above. The range of rotation of the outer tube 40 can be limited by the two stop surfaces 481 abutting against the cap 34.

[0073] When using the above-described preferred embodiments of this utility model, please refer to... Figures 7 to 9 As shown, first rotate the outer tube 40 to the position where the opening notch 46 faces forward, so that the opening notch 46 is directly opposite the sleeve opening 224 on the front side of the buckle groove 223. At this time, the gate rod body 20 can be rotated backward. During the process, the buckle 18 disengages from the buckle groove 223 and opens the opening 14. Then, the hook or knot or other ring-shaped object can be fitted onto the buckle body 10 by the buckle 18. Finally, return the gate rod body 20 and the outer tube 40 to their original positions and close the opening 14 to complete the operation of connecting the hook or knot to the connecting buckle 100 with the cap of the pivot assembly.

[0074] This utility model, through the design of the cap 34 fitting onto the head 322, forms an insulating and buffering protective structure for the head 322. This can prevent damage that may be caused by repeated impacts of the two stop surfaces 481 on the head 322 after multiple rotations of the outer tube 40. As a result, the rivet 32 ​​is less likely to loosen between the two pivot holes 222, and the head 322 protruding from the gate rod body 22 will not be exposed, thus producing an insulating effect.

[0075] In addition to the preferred embodiment described above, this utility model may also omit the outer tube 40, instead using a spring connected between the gate rod 20 and the pivot 16 to return the gate rod 20 to its original position. In this configuration, the lower convex ring 227, the upper convex ring 228, the first annular groove 21, and the second annular groove 23 are not formed around the gate rod 20, and the first washer 42 is not required around the gate rod body 22. In this case, the first insulating layer 241 and the second insulating layer 242 of the gate rod insulating layer 24 can be configured such that the upper edge of the first insulating layer 241 and the lower edge of the second insulating layer 242 are adjacent to or connected as a single unit, preventing the outer surface of the gate rod body 22 from being exposed.

[0076] In addition to the preferred embodiment described above, in which the connecting buckle 100 of the pivot assembly with a cap has an insulating layer on the surface of the buckle body 10, the gate rod body 20, and the outer tube 40, in other preferred embodiments, the connecting buckle 100 of the pivot assembly with a cap may also be configured such that the surface of the buckle body 10, the gate rod body 20, and the outer tube 40 does not have an insulating layer.

[0077] The above description is only a preferred and feasible embodiment of this utility model. Any equivalent changes made by applying the specification and claims of this utility model should be included within the patent scope of this utility model.
