Description

Technical Field

[0001] This utility model belongs to the field of pet climbing frame manufacturing, specifically relating to a novel round tube end plug and a connector for pet climbing frames. Background Technology

[0002] The applicant's prior patent CN 222351101 U, entitled "A Circular Tube End Plug", includes a circular tube (1) and a circular plate (2). The upper end face of the circular tube (1) is provided with the circular plate (2). The diameter of the circular tube (1) is smaller than the diameter of the circular plate (2), and multiple fastening ribs (3) are provided longitudinally on the outer circular surface of the circular tube (1). The upper end face of the circular plate (2) is provided with a through hole (21), and the through hole (21) penetrates the upper and lower end faces of the circular plate (2). The diameter of the through hole (21) is smaller than the diameter of the circular tube (1). The lower end face of the circular plate (2) is provided with a circular tube sleeve (4), and the central through hole of the circular tube sleeve (4) is connected to the through hole (21). The diameter of the central through hole matches the diameter of the through hole (21). Two protrusions (5) are provided on the inner wall surface of the circular tube sleeve (4). The center line of symmetry of the circular plate (2) coincides with the center line of symmetry of the circular tube (1); the center line of symmetry of the through hole (21) coincides with the center line of symmetry of the circular plate (2). Multiple reinforcing plates (8) are provided between the outer circular surface of the circular tube sleeve (4) and the inner wall surface of the circular tube (1), and the multiple reinforcing plates (8) are equidistantly arranged. The front end of the protrusion (5) is provided with a guide slope (51). A novel round tube end plug connector includes a round tube end plug and a round sleeve (6). The upper end face of the round sleeve (6) is provided with a partition plate (7), and the upper end face of the partition plate (7) is provided with a mounting hole (71) that passes through the upper and lower end faces of the partition plate (7). The outer diameter of the round sleeve (6) matches the diameter of the central through hole of the round tube sleeve (4). The outer surface of the round sleeve (6) is provided with two "7"-shaped grooves (61). The vertical groove segment (611) in the "7"-shaped groove (61) passes through the lower end face of the round sleeve (6). The round sleeve (6) is installed in the round tube sleeve (4) when the round sleeve body is inserted into the central through hole of the round tube sleeve (4) and the protrusion (5) is in concave-convex fit with the corresponding "7"-shaped groove (61). The upper end face of the round sleeve (6) is flush with the upper end face of the round plate (2). The width of the vertical groove (611) in the "7"-shaped groove (61) matches the length of the protrusion (5), and the width of the horizontal groove (612) in the "7"-shaped groove (61) matches the width of the protrusion (5), and the length of the horizontal groove (612) is greater than the length of the protrusion (5). A protrusion (613) is provided between the horizontal groove (612) and the vertical groove (611). The mounting hole (71) is a threaded hole. Its disadvantage is that: the inner wall surface of the round tube sleeve in this kind of round tube end plug is provided with two protrusions. The round tube end plug is connected to the two "7"-shaped grooves on the outer surface of the round sleeve in the mounting part through the protrusions to form a new type of round tube end plug connector. Through the connection structure of the protrusion and the groove, the round tube end plug and the mounting part are prone to loosening during use (when the pet climbs and jumps on the pet climbing frame, the entire pet climbing frame will vibrate, and at this time the new type of round tube end plug connector, which is part of the pet climbing frame, will also be affected by the vibration). Utility Model Content

[0003] Design objective: To design a new type of round tube end plug and a connector for pet climbing frames that not only has a good anti-loosening effect after the threaded connection between the round tube end plug and the connector, but also has good load-bearing capacity after connection.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The central through hole of the circular tube sleeve is a threaded hole, and the upper end face of the circular plate has a through hole that penetrates both the upper and lower ends of the circular plate and is connected to the threaded hole. The diameter of the threaded hole matches the diameter of the through hole, and the center line of symmetry of the threaded hole coincides with the center line of symmetry of the through hole. This design is one of the technical features of this utility model. The purpose of this design is that: when the central through hole of the circular tube sleeve is a threaded hole, and the upper end face of the circular plate has a through hole that penetrates both the upper and lower ends of the circular plate and is connected to the threaded hole, and the diameter of the threaded hole matches the diameter of the through hole, and the center line of symmetry of the threaded hole coincides with the center line of symmetry of the through hole, when the circular tube sleeve body and the connector are fixedly connected by a threaded connection to form a connector for a pet climbing frame, the connector for a pet climbing frame using a threaded connection has a better anti-loosening effect during use (compared to our company's existing patented products).

[0006] 2. The design of having a circular groove on the upper surface of the circular plate, with the diameter of the groove being larger than the diameter of the through hole, is the second technical feature of this utility model. The purpose of this design is that: the upper surface of the circular plate has a circular groove with a diameter larger than the diameter of the through hole, and the thickness of the annular protrusion is less than or equal to the depth of the circular groove. Thus, when the circular tube sleeve body and the connector are fixedly connected by threads, the upper surface of the annular protrusion is lower than or flush with the upper surface of the circular plate. This ensures that when the connector for the pet climbing frame is assembled with other components of the pet climbing frame, the upper surface of the circular plate and the assembly surfaces of other components are in full contact, thereby ensuring the assembly effect of the connector for the pet climbing frame with other components. Furthermore, the surface contact between the lower surface of the annular protrusion and the bottom surface of the circular groove ensures increased load-bearing capacity of the connected circular tube end plug and connector (the load-bearing capacity of the threaded connection between the circular tube sleeve body and the connector is...). The increased load-bearing capacity is achieved when the lower end face of the annular protrusion contacts the bottom surface of the circular groove. The combined effect of these two factors results in better load-bearing capacity for the connected tube end plug and connector. Furthermore, when the load-bearing capacity is the same, the tube sleeve body and connector are fixedly connected via threads to form a connector for pet climbing frames. In this type of connector, where only a threaded connection is used, the threaded connection bears the entire load. However, in this type of connector, while using a threaded connection, the lower end face of the annular protrusion contacts the bottom surface of the circular groove, allowing the annular protrusion to share some of the load. Therefore, compared to connectors without annular protrusions, the threads in connectors with annular protrusions have a longer service life.

[0007] 3. The design of rounding the lower end of the circular tube to form a guide end is the third technical feature of this utility model. The purpose of this design is that the rounded lower end of the circular tube forms a guide end, which facilitates the assembly of the circular tube sleeve body and the connecting parts.

[0008] 4. The screw seat in the screw connector has a threaded rod on its upper end face and a thread on its outer circumference. The screw connector is fixedly connected to the round tube end plug body after the screw seat and the round tube sleeve are threaded together. This is the fourth technical feature of this utility model. The purpose of this design is that the screw seat in the screw connector has a threaded rod on its upper end face and a thread on its outer circumference. The screw connector is fixedly connected to the round tube end plug body after the screw seat and the round tube sleeve are threaded together. In this way, the round tube sleeve body and the connector are fixedly connected by a threaded connection to form a connector for pet climbing frames. The threaded connection of the connector for pet climbing frames has a better anti-loosening effect during use.

[0009] 5. The upper part of the outer circular surface of the screw seat is provided with an annular protrusion; the design that the thickness of the annular protrusion is less than or equal to the depth of the circular groove is the fifth technical feature of this utility model. The purpose of this design is that: the upper part of the outer circular surface of the screw seat is provided with an annular protrusion; the thickness of the annular protrusion is less than or equal to the depth of the circular groove, so that when the circular tube sleeve body and the connector are fixedly connected by a threaded connection to form a connector for a pet climbing frame, the lower end face of the annular protrusion makes surface contact with the bottom surface of the circular groove, which can ensure that the load-bearing capacity of the connected circular tube end plug and connector is improved (the load-bearing capacity of the threaded connection of the circular tube sleeve body and the connector, and the increased load-bearing capacity when the lower end face of the annular protrusion makes surface contact with the bottom surface of the circular groove, the two combined make the connected circular tube end plug and connector have better load-bearing capacity).

The upper end face of the circular tube is provided with a circular plate, and the lower end face of the circular plate is provided with a circular tube sleeve located inside the tube hole of the circular tube.

The central through hole of the circular tube sleeve is a threaded hole. The upper end face of the circular plate is provided with a through hole penetrating both the upper and lower ends of the circular plate and communicating with the threaded hole. The diameter of the threaded hole matches the diameter of the through hole, and the center line of symmetry of the threaded hole coincides with the center line of symmetry of the through hole.

[0011] Technical Solution 2: A connector for a pet climbing frame, comprising a novel round tube end plug and a screw connector, wherein the upper end face of the screw seat in the screw connector is provided with a threaded rod, and the outer circular surface of the screw seat is provided with a thread, and the screw connector is fixedly connected to the round tube end plug body after the screw seat and the round tube sleeve are threaded together.
