Description

Technical Field

[0001] The utility model belongs to the field of pet climbing frame manufacturing, and specifically relates to a round tube end plug and a novel round tube end plug connector. Background Art

[0002] CN 211231176 U, titled "A round tube end plug connector", comprises a plug body filled in a round tube, the outer end of the plug body is provided with a plug surface, the plug surface is exposed from the end surface of the round tube, the plug body is fixed on the plug surface, the outer diameter of the plug body matches the inner diameter of the round tube, and a mounting piece is provided on the plug surface. A plurality of fastening ribs are provided on the outer side of the plug body, and the fastening ribs are extended perpendicularly to the plug surface. The outer circumference of the fastening ribs gradually decreases in the direction away from the plug surface. A plurality of positioning holes are provided on the outer surface of the plug surface. A plug opening is provided at one end of the plug body away from the plug surface, and a guide surface is provided around the edge of the plug opening, and the guide surface is an inclined surface. A plurality of reinforcing ribs are provided inside the plug body. A boss is provided on the plug surface toward the inner center of the plug body, and the mounting piece is provided in the boss. The mounting piece adopts one of a mounting screw hole or a mounting stud. The center of the mounting piece coincides with the center of the plug surface, and the mounting direction of the mounting piece extends in the vertical direction of the plug surface. The radius of the plug surface is larger than the outer diameter of the plug body, and the edge of the plug surface and the plug body have a uniform transition. The shortcoming is that the mounting piece and the round tube end plug in this type of round tube end plug connector are an integrated structure. Since the round tube end plug and the mounting piece are inseparable, the company needs to produce a round tube end plug connector with different mounting piece specifications (i.e., mounting screw holes of different sizes) to meet the demand. This not only increases the overall production cost of a round tube end plug connector (the overall cost of different mounting piece specifications), but also causes inventory pressure on the company (the sales and usage of a round tube end plug connector with different mounting piece specifications is different). Utility Model Content

[0003] Design purpose: In order to avoid the shortcomings of the background technology, a round tube end plug and a new round tube end plug connector are designed that can not only reduce production costs, but also reduce the inventory pressure of the enterprise, while being easy to disassemble and assemble, and having good use effect and long service life.

[0007] 3. The upper end surface of the circular sleeve is provided with a partition plate, and the upper end surface of the partition plate is provided with a mounting hole that passes through the upper and lower end surfaces of the partition plate. The outer diameter of the circular sleeve matches the diameter of the central through hole of the circular tube sleeve. Two "7"-shaped grooves are provided on the outer surface of the circular sleeve. The vertical groove sections in the "7"-shaped grooves pass through the lower end surface of the circular sleeve. The design that the circular sleeve is installed in the circular tube sleeve when the circular sleeve body is plug-fitted with the central through hole of the circular tube sleeve and the convex block is concavely matched with the corresponding "7"-shaped groove is the third technical feature of the utility model. The purpose of this design is: first, the circular sleeve in the new round tube end plug connector is detachable from the circular plate and the circular tube sleeve with an integral structure, so that the circular plate and the circular tube sleeve with an integral structure can be produced in a standardized and unified manner, and the circular sleeve can be produced in different specifications, which not only reduces the production cost of the new round tube end plug connector, but also reduces the inventory pressure of the enterprise; second, the upper end face of the circular plate is provided with a through hole and the through hole passes through the upper and lower end faces of the circular plate, the symmetry center line of the through hole coincides with the symmetry center line of the circular plate and the diameter of the through hole is smaller than the diameter of the circular tube, the lower end face of the circular plate is provided with a circular tube sleeve and the central through hole of the circular tube sleeve is connected with the through hole, the diameter of the central through hole matches the diameter of the through hole, and two protrusions are provided on the inner wall surface of the circular tube sleeve ; The upper end surface of the circular sleeve is provided with a partition plate and the upper end surface of the partition plate is provided with mounting holes that pass through the upper and lower end surfaces of the partition plate, the outer diameter of the circular sleeve matches the diameter of the central through hole of the circular tube sleeve, and two "7"-shaped grooves are provided on the outer surface of the circular sleeve, and the vertical groove sections in the "7"-shaped grooves pass through the lower end surface of the circular sleeve, and the circular sleeve is installed in the circular tube sleeve when the circular sleeve body is plug-fitted with the central through hole of the circular tube sleeve and the protrusion is concave-convexly matched with the corresponding "7"-shaped groove; the width of the vertical groove section in the "7"-shaped groove matches the length of the protrusion, and the width of the transverse groove section in the "7"-shaped groove matches the width of the protrusion and the length of the transverse groove section is greater than the length of the protrusion, so that the circular sleeve and the circular plate and circular tube sleeve with an integrated structure can be quickly disassembled and assembled.

[0008] 4. A protrusion is provided between the transverse groove section and the vertical groove section; the front end of the protrusion is provided with a guide bevel, which is the fourth technical feature of the utility model. The purpose of such design is: a protrusion is provided between the transverse groove section and the vertical groove section, and the front end of the protrusion is provided with a guide bevel; first, a protrusion is provided between the transverse groove section and the vertical groove section, and after the protrusion and the transverse groove section are matched, the protrusion can play a certain limiting role on the protrusion (a relatively large external force is required for the protrusion to move to the vertical groove section through the protrusion, so as to realize the rapid separation of the circular sleeve and the circular plate and the circular tube sleeve with an integral structure). Such a new type of circular tube end plug connector is not easy to separate from each other during use; second, the front end of the protrusion is provided with a guide bevel, and when the circular sleeve and the circular plate with an integral structure are installed, the protrusion can realize the concave-convex match between the protrusion and the transverse groove section more labor-savingly through the protrusion.
