The functional component includes one or more of a flat diving platform, an arc diving platform, a cat room or a cat nest. It also includes a cat toy installed on the functional component, and the cat toy includes a marble. The outer surface of the column is covered with fabric or wound with a claw grinding rope. The connection position adopts a bolt connection structure and is arranged on the end face of the column. The upper and / or lower ends of the columns in this type of cat climbing frame are provided with connection positions (for connecting functional components, which include one or more of a flat diving platform, an arc-shaped diving platform, a cat house or a cat nest), and the connection positions adopt a bolt connection structure, that is, the bolt connection structure between the columns realizes mutual connection and installation of the functional components between the columns. However, the bolt connection structure adopted at the connection position not only makes the connection between the columns, the connecting functional components and the columns more time-consuming and labor-intensive, but also the bolt connection structure (that is, threaded connection) is prone to loosening during use, that is, the connection effect is relatively poor.

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

[0005] 1. An annular protrusion is provided in the middle of the cylinder, two "7"-shaped grooves are provided on the outer circumferential surface of one end of the cylinder, and two "7"-shaped grooves are provided on the outer circumferential surface of the other end of the cylinder, the vertical groove section in the "7"-shaped groove passes through the outer end surface of the end of the cylinder, and a protrusion is provided between the horizontal groove section and the vertical groove section in the "7"-shaped groove, which is one of the technical features of the utility model. The purpose of such design is that an annular protrusion is provided in the middle of the cylinder, two "7"-shaped grooves are provided on the outer circumferential surface of one end of the cylinder and two "7"-shaped grooves are provided on the outer circumferential surface of the other end of the cylinder, the vertical groove section in the "7"-shaped groove passes through the outer end surface of the end of the cylinder, and a protrusion is provided between the transverse groove section and the vertical groove section in the "7"-shaped groove. The coordinated use of the double-headed connector and the two round tube end plugs can enable the two round tubes and functional components (such as a flat diving platform and an arc-shaped diving platform) to be quickly connected, and the setting of the protrusion can prevent the connected double-headed connector and the corresponding round tube end plug from loosening, that is, the connection effect is good. In addition, the end face of the annular protrusion is in surface-to-surface contact with the plug surface of the corresponding round tube end plug, which can improve the bearing capacity of the double-headed connector.

[0006] 2. The design that the outer circumferential surface of the annular protrusion is provided with a plurality of grooves is the second technical feature of the utility model. The purpose of such design is that the outer circumferential surface of the annular protrusion is provided with a plurality of grooves, and the setting of the plurality of grooves can not only improve the roundness of the outer circumferential surface of the annular protrusion, but also reduce the weight of the double-headed connector and save the use of materials (reduce the production cost of the double-headed connector).

[0007] 3. The design that the upper end surface of the cylinder is provided with a through hole that passes through the upper and lower end surfaces of the cylinder is the third technical feature of the utility model. The purpose of this design is that the upper end surface of the cylinder is provided with a through hole that passes through the upper and lower end surfaces of the cylinder. The provision of the through hole can not only reduce the weight of the double-headed connector, but also save the use of materials (reduce the production cost of the double-headed connector).

[0008] 4. The cross section of the protrusion is arc-shaped, and the height of the protrusion is 10% to 30% of the depth of the "7"-shaped groove, which is the fourth technical feature of the utility model. The purpose of this design is that the cross section of the protrusion is arc-shaped, and the height of the protrusion is 10% to 30% of the depth of the "7"-shaped groove. Such a structural design ensures that the subsequent double-headed connector and the round tube end plug use a relatively large external force, and the block can be moved to the vertical groove section through the arc-shaped protrusion, so as to realize the separation of the circular sleeve and the round tube end plug and avoid the jamming of the two.

[0009] 5. The design that both the upper and lower ends of the cylinder are chamfered is the fourth technical feature of the utility model. The purpose of this design is that both the upper and lower ends of the cylinder are chamfered, which makes it easier for the double-headed connector to be inserted into the corresponding central through hole, thereby improving the use effect of the double-headed connector.

[0016] Example 1: Refer to the attached Figure 1-Figure 4 A double-end connector for a pet climbing frame comprises a cylinder 1, an annular protrusion 2 is provided in the middle of the cylinder 1, two "7"-shaped grooves 3 are provided on the outer circumferential surface of one end of the cylinder 1, and two "7"-shaped grooves 3 are provided on the outer circumferential surface of the other end of the cylinder 1, a vertical groove section 31 in the "7"-shaped groove 3 passes through the outer end surface of the cylinder end, and a protrusion 33 is provided between the horizontal groove section 32 and the vertical groove section 31 in the "7"-shaped groove 3.

[0017] The outer circumferential surface of the annular protrusion 2 is provided with a plurality of grooves 21. The upper end surface of the cylinder 1 is provided with a through hole 11 penetrating the upper and lower end surfaces of the cylinder 1. The cross section of the protrusion 33 is arc-shaped, and the height value of the protrusion 33 is 10% to 30% of the depth value of the "7"-shaped groove 3. Preferably, the height value of the protrusion 33 is 20% of the depth value of the "7"-shaped groove 3. The upper and lower ends of the cylinder 1 are both chamfered ends 12.

[0018] The following is one of the connection and use methods of a double-ended connector for a pet climbing frame during the construction of the pet climbing frame, comprising two round tube end plugs 5, two clamping blocks 51 are arranged on the inner wall surface of the central through hole of the round tube end plug 5, and a plurality of fastening ribs 52 are longitudinally arranged on the outer circumference of the round tube end plug 5. When in use, a round tube end plug 5 is inserted and installed in one end hole of one round tube, and another round tube end plug 5 is inserted and installed in one end hole of the other round tube. Then, one end of the double-ended connector is inserted into the central through hole of one of the round tube end plugs 5. The double-headed connector is fixedly connected to the round tube end plug 5 when one end of the double-headed connector is plugged into the central through hole of the round tube end plug 5 and the block 51 is concavely and convexly matched with the corresponding transverse groove section 32 in the "7"-shaped groove 3. Then, the plug-in through hole in the functional component (such as a flat diving platform or an arc diving platform) (the plug-in through hole is provided on the plate body of the functional component, and the plug-in through hole passes through the upper and lower end surfaces of the plate body, and the diameter of the plug-in through hole matches the diameter of the annular protrusion 2) is plugged into the annular protrusion 2, and then the other end of the double-headed connector is inserted into the other round tube end plug 5 The double-headed connector is in the center through hole of the other side end of the double-headed connector and is plugged into the center through hole of another round tube end plug 4, and the clamping block 51 is fixedly connected to the round tube end plug 5 when it is concave-convexly matched with the transverse groove section 32 in the corresponding "7"-shaped groove 3 (the diameter of the round tube end plug 5 is larger than the annular protrusion 2). At this time, the two round tubes are connected through a double-headed connector and two round tube end plugs 5, and functional components (such as a flat diving platform and an arc diving platform) are also installed between the two round tubes; the round tube end plug 5 is an injection molded part, and the double-headed connector is an injection molded part; in the clamping block After the convex-concave fit between 51 and the corresponding transverse groove section, the arc-shaped protrusion can play a certain limiting role on the block 51 (a relatively large external force is required for the block 51 to move into the vertical groove section through the arc-shaped protrusion, thereby realizing the rapid separation of the double-headed connector and the round tube end plug 5), thus ensuring that the round tube end plug 5 and the double-headed connector are not easily loosened and separated from each other after the two are snap-fitted; in addition, the front end head of the block 51 is provided with a guiding inclined surface, so that when the round tube end plug 5 and the double-headed connector are snap-fitted and installed, the block 51 can realize the convex-concave fit between the block 51 and the transverse groove section through the arc-shaped protrusion with more effort.
