Description

Technical Field

[0001] This utility model belongs to the field of pet climbing frame manufacturing technology, specifically relating to a pet climbing frame connection structure. Background Technology

[0002] The applicant's prior patent CN 222577064 U, entitled "A Pet Climbing Tree Clip," includes a first ring, a second ring, and an annular connecting plate. The diameter of the first ring is larger than the diameter of the second ring, and the heights of the first and second rings match. The lower end face of the annular connecting plate has the first and second rings, which are concentrically arranged. The outer surface of the first ring is flush with the outer surface of the annular connecting plate, and the inner surface of the second ring is flush with the inner surface of the annular connecting plate. Two protrusions are provided on the inner surface of the second ring. Multiple reinforcing plates are provided between the inner surface of the first ring and the outer surface of the second ring. The first ring, second ring, annular connecting plate, protrusions, and reinforcing plates are integrally injection molded. The front end of the protrusions has a guide bevel. The lower end face of the reinforcing plate is flush with the lower end face of the second ring, and the upper end face of the reinforcing plate is fixedly connected to the upper end face of the annular connecting plate. The junction of the annular connecting plate and the first ring is rounded to form an arc-shaped connecting part. The device includes a pet climbing frame clip and a double-ended connector. The double-ended connector has an annular protrusion in the center of its cylinder. Two "7"-shaped grooves are located on the outer surface of one end of the cylinder, and two "7"-shaped grooves are located on the outer surface of the other end of the cylinder. The vertical grooves in the "7"-shaped grooves extend through the outer end face of the corresponding cylinder end. When the double-ended connector is inserted into the second ring at one end of the cylinder and the protrusion engages with the corresponding "7"-shaped groove, it achieves a fixed connection with the pet climbing frame clip. A protrusion is located between the horizontal and vertical grooves in the "7"-shaped groove, and the cross-section of the protrusion is arc-shaped. Its shortcomings are: this type of pet climbing frame snap-fit ​​structure connects the pet climbing frame snap-fit ​​and the double-headed connector by using the protrusion block and the corresponding "7" shaped groove to achieve the snap-fit ​​structure. The snap-fit ​​structure achieved by the protrusion block and the "7" shaped groove makes the pet climbing frame snap-fit ​​and the double-headed connector prone to loosening during use (when the pet climbs or jumps on the pet climbing frame, the entire pet climbing frame will vibrate, and at this time the pet climbing frame snap-fit ​​structure, as part of the pet climbing frame, will also be affected by the vibration). Utility Model Content

[0003] Design objective: To design a pet climbing frame connection structure that not only has a good anti-loosening effect but also a good load-bearing capacity.

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

[0005] 1. The upper end face of the circular tube in the circular tube end plug is provided with a circular plate, and the lower end face of the circular plate is provided with a circular tube sleeve, which is located inside the tube hole of the circular tube. The inner wall surface of the central through hole of the circular tube sleeve is provided with a third thread. The upper end face of the circular plate is provided with a through hole that penetrates the upper and lower ends of the circular plate and communicates with the central through hole of the circular tube sleeve. The diameter of the central through hole of the circular tube sleeve matches the diameter of the through hole, and the symmetrical center line of the central through hole of the circular tube sleeve coincides with the symmetrical center line of the through hole; the outer circular surface of the column in the double-ended connector is provided with an annular protrusion and The annular protrusion is located in the center of the column. The outer circular surface of the column is provided with a first thread and a second thread, and the first thread and the second thread are located on both sides of the annular protrusion. The double-ended connector is fixedly installed on the round tube end plug after the first thread and the third thread are threaded together. At this time, the column section where the second thread is located is outside the round tube end plug. Alternatively, the double-ended connector is fixedly installed on the round tube end plug after the second thread and the third thread are threaded together. At this time, the column section where the first thread is located is outside the round tube end plug. This design is one of the technical features of this utility model.The purpose of this design is as follows: the upper end face of the circular tube in the circular tube end plug is provided with a circular plate, the lower end face of the circular plate is provided with a circular tube sleeve, and the circular tube sleeve is located inside the tube hole of the circular tube. The inner wall surface of the central through hole of the circular tube sleeve is provided with a third thread. The upper end face of the circular plate is provided with a through hole that penetrates the upper and lower ends of the circular plate and is connected to the central through hole of the circular tube sleeve. The diameter of the central through hole of the circular tube sleeve matches the diameter of the through hole, and the symmetrical center line of the central through hole of the circular tube sleeve coincides with the symmetrical center line of the through hole. The outer circular surface of the column in the double-ended connector is provided with an annular protrusion, and the annular protrusion is located on the column. At the very center, the outer circumference of the column is provided with a first thread and a second thread, which are located on both sides of the annular protrusion. The double-ended connector is fixedly installed on the round tube end plug after the first thread and the third thread are threaded together. At this time, the column section with the second thread is located outside the round tube end plug. Alternatively, the double-ended connector is fixedly installed on the round tube end plug after the second thread and the third thread are threaded together. At this time, the column section with the first thread is located outside the round tube end plug. When the round tube end plug and the double-ended connector are fixedly connected by threads to form a pet climbing frame connection structure, a threaded connection is used. A new pet climbing frame connection structure offers better anti-loosening performance during use (compared to our existing patented products). Furthermore, after the threaded connection between the round tube end plug and the double-ended connector, the annular protrusion makes surface-to-surface contact with the circular plate inside the round tube end plug. This improves the overall load-bearing capacity of the pet climbing frame connection structure formed by the threaded connection of the round tube end plug and the double-ended connector (the combined load-bearing capacity of the threaded connection of the round tube end plug and the double-ended connector, and the increased load-bearing capacity when the annular protrusion makes surface-to-surface contact with the circular plate, result in better load-bearing capacity for the connected round tube end plug and double-ended connector). This is a pet climbing frame connection structure where the round tube sleeve and the double-ended connector are fixedly connected by threads under the same load-bearing force. In a pet climbing frame connection structure that only uses threads, the threads will bear the entire load. However, in another pet climbing frame connection structure, while using threads, the lower end face of the annular protrusion makes full contact with the bottom face of the circular groove. In this way, the annular protrusion can share part of the load-bearing force. Therefore, compared to a pet climbing frame connection structure without an annular protrusion, the threaded part of the pet climbing frame connection structure has a longer service life.

[0006] 2. It also includes a locking member, wherein the inner wall surface of the central through hole of the inner cylinder of the locking member is provided with a fourth thread. The locking member is fixedly installed on the double-ended connector after the fourth thread is threadedly engaged with the second thread located outside the end plug of the round tube, or the locking member is fixedly installed on the double-ended connector after the fourth thread is threadedly engaged with the first thread located outside the end plug of the round tube. This design is the second technical feature of this utility model. The purpose of this design is to include a locking component. The inner wall of the central through hole of the inner cylinder of the locking component is provided with a fourth thread. The locking component is fixedly installed on the double-ended connector after the fourth thread is threadedly engaged with the second thread located outside the round tube end plug, or the locking component is fixedly installed on the double-ended connector after the fourth thread is threadedly engaged with the first thread located outside the round tube end plug. This pet climbing frame connection structure (round tube end plug, double-ended connector and locking component) can fix the round tube as the column and the climbing frame platform to a fixed connection (the climbing frame platform is provided with a double-ended connector that passes through the upper and lower ends of the climbing frame platform. The round tube end plug is inserted into the upper end hole of the round tube as the column. Then the lower end of the double-ended connector is screwed into the round tube end plug. The upper end of the double-ended connector passes through the double-ended connector and extends out of the upper end face of the climbing frame platform. Then the locking component is screwed into the upper end of the double-ended connector).

[0007] 3. The locking component includes an inner cylinder, an outer cylinder, and a connecting plate. The lower end face of the connecting plate is provided with an inner cylinder and an outer cylinder, with the inner cylinder located inside the outer cylinder. The upper end face of the connecting plate is provided with a circular hole that passes through both the upper and lower end faces of the connecting plate. The diameter of the central through hole of the inner cylinder matches the diameter of the circular hole, and the symmetrical center line of the central through hole of the inner cylinder coincides with the symmetrical center line of the circular hole. The design of providing multiple auxiliary connecting plates on the outer wall surface of the inner cylinder and the inner wall surface of the outer cylinder is the third technical feature of this utility model. The purpose of this design is that the locking component includes an inner cylinder, an outer cylinder, and a connecting plate. The lower end face of the connecting plate is provided with an inner cylinder and an outer cylinder, with the inner cylinder located inside the outer cylinder. The upper end face of the connecting plate is provided with a circular hole that passes through both the upper and lower end faces of the connecting plate. The diameter of the central through hole of the inner cylinder matches the diameter of the circular hole, and the symmetrical center line of the central through hole of the inner cylinder coincides with the symmetrical center line of the circular hole. The outer wall surface of the inner cylinder and the inner wall surface of the outer cylinder are provided with multiple auxiliary connecting plates. The locking component with this structure not only has good overall strength but also has a lighter overall weight.

[0008] 4. 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, and the depth of the circular groove being greater than or equal to the thickness of the annular protrusion, is the fourth technical feature of this utility model. The purpose of this design is that: the circular groove on the upper surface of the circular plate, with its diameter larger than the diameter of the through hole, and the depth of the circular groove being greater than or equal to the thickness of the annular protrusion, allows for surface-to-surface contact between the lower surface of the annular protrusion and the bottom surface of the circular groove. This ensures the load-bearing capacity of the connected circular tube end plug and the double-ended connector. Simultaneously, when the circular tube end plug and the double-ended connector are fixedly connected by threads, the upper surface of the annular protrusion is lower than the upper surface of the circular plate, or the upper surface of the annular protrusion is flush with the upper surface of the circular plate. This ensures that when the pet climbing frame connection structure is assembled with the pet climbing platform, the upper surface of the circular plate and the lower surface of the pet climbing platform can achieve surface-to-surface contact, thereby ensuring the assembly effect of the pet climbing frame connection structure with other components of the pet climbing frame.

[0009] Technical solution: A pet climbing frame connection structure includes a circular tube end plug and a double-ended connector. The upper end face of the circular tube in the circular tube end plug is provided with a circular plate, and the lower end face of the circular plate is provided with a circular tube sleeve located within the tube hole of the circular tube.

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 the through hole communicates with the central through hole of the circular tube sleeve. The diameter of the central through hole of the circular tube sleeve matches the diameter of the through hole, and the symmetrical center line of the central through hole of the circular tube sleeve coincides with the symmetrical center line of the through hole. The double-ended connector has an annular protrusion on the outer circular surface of the column, which is located in the middle of the column. The outer circular surface of the column has a first thread and a second thread, which are located on both sides of the annular protrusion. The double-ended connector is fixedly installed on the end plug of the round tube after the first thread and the third thread are threaded together. At this time, the column section where the second thread is located is outside the end plug of the round tube. Alternatively, the double-ended connector is fixedly installed on the end plug of the round tube after the second thread and the third thread are threaded together. At this time, the column section where the first thread is located is outside the end plug of the round tube.
