Description

Technical Field

[0001] This utility model relates to a connecting buckle; in particular, it refers to a connecting buckle with a detachable washer ring. Background Technology

[0002] The existing connecting ring includes a ring body with an opening. The ring body has a buckle head and a pivot part at the upper and lower ends of the opening, respectively. The pivot part has a shaft hole and a gate rod is pivotally connected to the pivot part. The upper end of the gate rod is fastened to the buckle head. An outer tube that can rotate or move outward along the axial direction of the gate rod is fitted around the gate rod. The overlap between the buckle head and the gate rod is covered or exposed by the movement of the outer tube in two positions, thereby opening or closing the opening with the gate rod.

[0003] While the existing connecting rings can fix or release the gate rod body from the outer tube, the gate rod body has spaced-apart washers integrally formed on its outer circumferential surface. This allows the inner circumferential surface of the outer tube to contact the outer surfaces of the two washers as a reference surface for rotation or axial movement. However, since the two washers are integrally formed on the gate rod body, installing parts or accessories, such as springs used to return the outer tube to its original position, in the part of the gate rod body located between the two washers would be difficult and disassembly would be challenging during maintenance. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a connecting ring with a detachable washer ring. By designing that at least one of the two washer rings can be detached from the ring body, the convenience of assembling parts and maintenance can be improved when springs or other parts need to be installed on the part of the gate rod body located between the two washer rings.

[0005] To achieve the above objectives, this utility model provides a connecting buckle with a separable washer ring, comprising a buckle body, a gate rod body, and an outer tube. 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 at its lower and upper ends adjacent to the opening, respectively. The gate rod body is pivotally connected to the pivot portion at its lower end, and the upper end of the gate rod body is fastened to and overlaps with the buckle head, thereby closing the opening of the gate rod body. At least one annular groove is formed on the outer circumferential surface of the gate rod body. Two washer rings are attached to the outer circumferential surface of the gate rod body. The two washer rings are arranged vertically at intervals, and the outer surface of each washer ring protrudes from the outer circumferential surface of the gate rod body. At least one of the two washer rings is embedded in the at least one annular groove, and the washer ring embedded in the at least one annular groove is a C-shaped ring. The outer tube is fitted around the gate rod body, and the inner circumferential surface of the outer tube slidably abuts against the outer surface of each of the gaskets; the outer tube can move between a first position and a second position. When the outer tube is in the first position, the upper end of the outer tube covers the front side of the overlap between the buckle and the gate rod body; when the outer tube is in the second position, the overlap between the buckle and the gate rod body is exposed from the upper end of the outer tube.

[0006] In use, the outer tube is first moved from the first position to the second position, so that the overlap between the buckle and the gate rod body is exposed at the upper end of the outer tube. Then, the gate rod body, along with the outer tube, can be rotated backward relative to the pivot, opening the opening of the buckle body. A hook or knot, or other ring-shaped object, can then be fitted onto the buckle body through the buckle. Returning the gate rod body and the outer tube to their original positions closes the opening, completing the operation of attaching the hook or knot to the connecting buckle with the detachable washer.

[0007] The advantage of this invention lies in the fact that, since at least one of the two gaskets attached to the outer circumferential surface of the gate rod body is detachably attached, when a part needs to be placed in the portion of the gate rod body located between the two gaskets, the gasket can be removed first, the part or accessory placed in the gate rod body, and then the gasket can be re-embedded in the at least one annular groove. This allows for the smooth installation of parts or accessories into the gate rod body located between the two gaskets, improving the convenience of parts assembly and maintenance.

[0059] To more clearly illustrate this utility model, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figure 1 and Figure 2The image shows a preferred embodiment of the connecting buckle 100 with detachable washers. In the following description, directions will be defined by their relative positions in use: up / down, front / back, left / right, and inside / outside. In this preferred embodiment, the connecting buckle 100 with detachable washers is designed to be insulated and includes a buckle body 10, a gate rod body 20, two washers 30, and an outer tube 40.

[0060] Please refer to Figures 1 to 7 As shown, the buckle body 10 has a metal core 11 inside, and a buckle insulating layer 12 is formed on the outer surface of the metal core 11. An opening 14 is formed in the middle of the front side of the buckle insulating layer 12. A pivot portion 16 is provided at the lower end of the buckle body 10 adjacent to the opening 14. The pivot portion 16 has an insert plate 161, and the insert plate 161 has a shaft hole 162. A buckle head 18 is provided at the upper end of the buckle body 10 adjacent to the opening 14. A pair of grooves 181 are formed on the inner side of the buckle head 18. The pair of grooves 181 are located at the left and right positions on the inner side of the buckle head 18, respectively. A fixing hook 182 is provided at the lower end of the buckle head 18, and the fixing hook 182 is adjacent to the lower edge of the pair of grooves 181.

[0061] Please refer to Figures 2 to 7 As shown, the gate rod body 20 includes a gate rod body 22 and a gate rod insulation layer 24. A downward-opening groove 221 is provided at the lower end of the gate rod body 22, penetrating both the front and rear sides of the lower end of the gate rod body 22, forming two pivot holes 222 on the left and right sides of the lower end of the gate rod body 22. The groove 221 accommodates the insert plate 161 of the pivot part 16. The two pivot holes 222 communicate with the left and right sides of the shaft hole 162. A pivot element 23 passes through the two pivot holes 222 and the shaft hole 162, and the pivot element 23 has a head 231.

[0062] 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 adjacent to the left and right parts of the through opening 225 forms a pair of hooks 226. A convex ring 227 is formed on the outer peripheral surface of the gate rod 22 above the groove 221, and another convex ring 227 is formed on the outer peripheral surface of the gate rod 22 below the buckle groove 223. The two convex rings 227 are spaced apart vertically. The portion of the gate rod 22 located between the two convex rings 227 forms a waist 228. The waist 228 is located on the middle outer peripheral surface of the gate rod 22, and the front side of the waist 228 has a spring insertion hole 229.

[0063] The gate stem insulation layer 24 includes a first insulation layer 241 and a second insulation layer 242. The first insulation layer 241 is applied to the outer surface of the lower end of the gate stem body 22 by an insert injection molding process. The upper edge of the first insulation layer 241 is vertically spaced from the lower convex ring 227, forming an annular groove 25 between the upper edge of the first insulation layer 241 and the lower convex ring 227. The second insulation layer 242 is applied to the outer surface of the upper end of the gate stem body 22 by an insert injection molding process. The lower edge of the second insulation layer 242 is vertically spaced from the upper convex ring 227, forming another annular groove 25 between the lower edge of the second insulation layer 242 and the upper convex ring 227. The buckle groove 223 engages forward with the buckle 18 of the buckle body 10, so that the buckle 18 overlaps with the upper end of the gate rod body 20. 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 body 20 closes the opening 14 of the buckle body 10.

[0064] The two washer rings 30 are C-shaped rings, and the two washer rings 30 are respectively embedded in the two annular grooves 25, so that the two washer rings 30 are arranged in a vertically spaced manner. Specifically, each washer ring 30 has a washer ring body 31, and each washer ring body 31 is a C-shaped ring with equal thickness between its inner and outer surfaces. An insert 32 is connected to the inner surface of each washer ring body 31. Each insert 32 is wrapped in a C-shape and protrudes inward from the inner surface of each washer ring body 31. Each insert 32 is embedded and fixed in each annular groove 25. The inner surface of each washer ring body 31 without the insert 32 abuts against the outer surface of each protruding ring 227.

[0065] The lower side of the lower washer 30 abuts against the upper edge of the first insulating layer 241, and the outer surface of the lower washer 30 protrudes beyond the outer surface of the first insulating layer 241. The upper side of the upper washer 30 abuts against the lower edge of the second insulating layer 242, and the outer surface of the upper washer 30 protrudes beyond the outer surface of the second insulating layer 242. In other preferred embodiments, one of the two washer rings 30 may also be a ring and integrally connected to the outer circumferential surface of the gate rod body 22, such that only one of the two washer rings 30 can be detachably connected to the annular groove 25 of the gate rod body 20.

[0066] Please refer to Figure 2 and Figures 6 to 9 As shown, the outer tube 40 is a vertically arranged tube, and the outer surface of the outer tube 40 has an outer tube insulation layer 41. The outer tube 40 is fitted around the gate rod body 20. The inner circumferential surface of the outer tube 40 slidably abuts against the outer surface of the two gaskets 30, so that the outer tube 40 can rotate and move relative to the gate rod body 20 between a first position P1 and a second position P2.

[0067] When the outer tube 40 is located at the first position P1, the upper end of the outer tube 40 covers the sleeve opening 224 of the buckle groove 223 of the gate rod 20, that is, it covers the front side of the overlap between the gate rod 20 and the buckle 18. An opening notch 42 is formed at the upper end of the outer tube 40, the shape of which is slightly larger than the shape of the sleeve opening 224 of the buckle groove 223. When the outer tube 40 is located at the first position P1, the opening notch 42 faces a position relatively offset from the buckle groove 223. In this preferred embodiment, the opening notch 42 faces to the right when the outer tube 40 is located at the first position P1. An inwardly opening long groove 421 is formed on the bottom side of the opening notch 42. The long groove 421 is a long strip-shaped groove extending in the vertical direction and closed at the lower end. The upper end of the long groove 421 communicates with the opening notch 42.

[0068] A spiral spring 43 is fitted onto the waist 228 of the gate rod body 20. One end of the spiral spring 43 is inserted into the spring insertion hole 229 of the waist 228, and the other end of the spiral spring 43 is inserted into the long groove 421 of the outer tube 40. Through the restoring force provided by the spiral spring 43, when the opening notch 42 of the outer tube 40 is rotated to a position facing forward and directly opposite the sleeve opening 224 of the buckle groove 223, that is, when the outer tube 40 is rotated to the second position P2, and the overlap of the buckle 18 and the gate rod body 20 is exposed from the upper end of the outer tube 40, the outer tube 40 is released and can be driven back to the first position P1 by the spiral spring 43.

[0069] The bottom edge of the outer tube 40 is recessed to form an arc-shaped notch 44. The arc-shaped notch 44 has a stop surface 441 on each side corresponding to the clockwise and counterclockwise directions when viewed from above. The arc-shaped notch 44 accommodates the head 231 of the pivot element 23. One of the two stop surfaces 441 abuts against or is adjacent to the head 231. In this preferred embodiment, the surface of the head 231 has an insulating layer, and the stop surface 441 facing the counterclockwise direction when viewed from above abuts against the head 231. The abutment of the two stop surfaces 441 against the head 231 restricts the range of rotation of the outer tube 40 between the first position P1 and the second position P2.

[0070] When using the above-described preferred embodiments of this utility model, please refer to... Figures 8 to 10 As shown, first rotate the outer tube 40 to the second position P2, that is, rotate the outer tube 40 to the position where the opening notch 42 faces forward, so that the opening notch 42 is directly opposite the sleeve opening 224 on the front side of the buckle groove 223, exposing the overlap between the buckle 18 and the gate rod body 20. At this time, the gate rod body 20 can be rotated backward, during which the buckle 18 moves out of the buckle groove 223, opening the opening 14. Then, a 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 to close the opening 14, thus completing the operation of attaching the hook or knot to the connecting buckle 100 with the detachable washer.

[0071] The present invention is that during the process of installing the spiral spring 43 on the gate rod body 20, since the waist 228 is located between the two washers 30, and the outer surface of the waist 228 is more concave than the outer surface of the two washers 30, the two washers 30 will become an obstacle to fitting the spiral spring 43 onto the waist 228. However, this utility model benefits from the fact that the two washer rings 30 are detachable from the two annular grooves 25 of the gate rod body 20. Therefore, before installing the two washer rings 30 onto the gate rod body 20, the spiral spring 43 is first inserted into the gate rod body 20 from any side and moved to the waist 228. Then, the two washer rings 30 are embedded in the two annular grooves 25 of the gate rod body 20, and the spiral spring 43 can be smoothly installed onto the gate rod body 20. If any other parts need to be joined to the part of the gate rod body 20 located between the two washer rings 30, the same method can be used, which can improve the convenience of assembling parts and maintenance.

[0072] In addition to the preferred embodiment described above, in which an insulating layer is provided on the surfaces of the buckle body 10, the gate rod body 20, the head 231, and the outer tube 40, in other preferred embodiments, the connecting buckle 100 with separable washers can also be configured such that the surfaces of the buckle body 10, the gate rod body 20, the head 231, and the outer tube 40 do not have an insulating layer. In this case, the outer circumferential surface of the gate rod body 22 forms two annular grooves 25 at vertical intervals, and each washer 30 is then joined to each annular groove 25. In this case, the outer tube 40 without an insulating layer still slidably contacts the outer surfaces of the two washer 30 with its inner circumferential surface, using the outer surfaces of the two washer 30 as the reference surface when the outer tube 40 rotates around the gate rod body 20.

[0073] In addition to the preferred embodiment described above, in this utility model, the two washer rings 30 are detachably embedded in each of the annular grooves 25. Alternatively, one of the two washer rings 30 can be integrally connected to the gate rod body 22. In this case, only one of the two washer rings 30 can be detached from the gate rod body 20. However, since the spiral spring 43 can be smoothly inserted into the waist 228 of the gate rod body 20 from one side after removing one washer ring 30 from the gate rod body 20, this utility model still has the effect of easily installing the spiral spring 43 or other parts and accessories into the waist 228 of the gate rod body 20.

[0074] In addition to the preferred embodiment described above, where the outer tube 40 is rotatably fitted around the gate rod 20, the outer tube 40 of this invention can also be designed to slide along the axial direction of the gate rod 20 between a first position and a second position. In this case, the first position of the outer tube 40 is located at the top, and the second position is located at the bottom. When the outer tube 40 is still in the first position at the top, its upper end covers the overlap between the buckle 18 and the gate rod 20. When the outer tube 40 moves downward to the second position at the bottom, the overlap between the buckle 18 and the gate rod 20 is exposed, thereby releasing the gate rod 20. Then, the gate rod 20 can be rotated backward to open the opening 14.

[0075] 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.
