Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe clamps, in particular to a male and female joint structure used for a connecting rod of a plastic pipe clamp. Background Art

[0002] Most common plastic pipe clamps are fixed structures without additional connectors. Designing multiple clamps in one piece complicates the production mold design, making molding inconvenient. The clamps cannot rotate, and require high precision in the positioning of the pipes they fit. Some detachable clamps, with additional connecting rods, often use cylindrical plug-in structures like plug-in and screw-in connections. This hinders assembly, requiring a long travel and labor, and can also cause the clamps to loosen. Utility Model Content

[0003] The purpose of the present utility model is to solve the problem that the fixed structure of common plastic pipe clamps is complicated when multiple pipe clamps are designed as one, the design of the corresponding processing and production mold is inconvenient, the molding is inconvenient, and the pipe clamp cannot be rotated. The position accuracy of the adapted pipeline is required to be high. The connecting rod structure added by the partially detachable pipe clamp is mostly a common cylindrical plug-in structure such as plug-in and screw-in, which makes the assembly obstructed and laborious. There is also the problem of the pipe clamp loosening. A male and female joint structure for the connecting rod of the plastic pipe clamp is provided.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a male and female joint structure for a plastic pipe clamp connecting rod, comprising:

[0005] The male connector comprises a tower-shaped connector column, one end of which is provided with an inner abutment block, a middle section of which is provided with a plurality of inner retaining rings axially distributed, a connecting seat at the other end of which is provided, and a sealing ring is provided inside the connecting seat;

[0006] The female connector has a connector hole groove inside which is slidably engaged with the connector column. The side surfaces of the connector hole groove are extended with a groove and a countersunk hole corresponding to the inner clamping ring and the sealing ring respectively. The end of the female connector is spliced ​​and abutted against the end surface of the connecting seat. The male connector and the female connector are arranged on the side surfaces of the first pipe clamp and the second pipe clamp. The male connector and the female connector on the opposite sides of the adjacent first pipe clamp and the second pipe clamp are plugged in and positioned and assembled.

[0007] As a further description of the above technical solution:

[0008] A wedge-shaped or arc-shaped joining surface is provided on the edge of the inner abutment block, and the joining surface is tightly joined and positioned with the positioning groove at the inner end of the joint hole groove.

[0009] As a further description of the above technical solution:

[0010] The diameter of the inner snap ring increases continuously in the direction from the inner abutment block to the connecting seat, and the corresponding snap groove is tightly engaged with the inner snap ring.

[0011] As a further description of the above technical solution:

[0012] The inner and outer sides of the inner clamping ring and the inner side of the sealing ring are sequentially provided with a wedge-shaped or arc-shaped first abutting surface, a second abutting surface and a third abutting surface that are tightened and extended outward.

[0013] As a further description of the above technical solution:

[0014] The included angle between the first abutting surface and the axis of the joint column is 0-45°, and the included angle between the second abutting surface and the axis of the joint column is 90-135°.

[0015] As a further description of the above technical solution:

[0016] A wedge-shaped or arc-shaped guide surface is provided on the outer edge of the countersunk hole.

[0017] As a further description of the above technical solution:

[0018] An extension interface is provided at the connection between the outer side of the connecting seat and the first pipe clamp or the second pipe clamp.

[0019] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] This male and female connector structure is designed with an inner retaining ring that continuously increases in diameter in the direction from the inner abutment block to the connecting seat. The corresponding retaining groove is designed to tightly engage with the inner retaining ring. When assembling the male and female connectors, compared with common cylindrical plug-in structures such as plug-in and screw-in connections, this tower-shaped plug-in structure has a reduced plug-in resistance stroke, making installation of the male and female connectors more labor-saving. By optimizing the pipe diameter tolerance design of the male and female connectors, it meets the design requirements of being able to rotate without wearing the pipe clamp, making it suitable for pipelines with wider positioning requirements in actual application scenarios. The optimized male and female connector design and the chamfered angles of the steps in the insertion and extraction directions on the connectors make the insertion force of the pipe clamp smaller, facilitating assembly, and the extraction force larger, preventing the two pipe clamps from falling off during use.

[0029] See also Figure 1-3 The utility model provides a technical solution: a male and female joint structure for a plastic pipe clamp connecting rod, comprising:

[0030] The male connector 1 comprises a tower-shaped connector column 11, an inner abutment block 12 being provided at one end of the connector column 11, a plurality of inner retaining rings 13 being axially distributed in the middle section of the connector column 11, a connecting seat 15 being provided at the other end of the connector column 11, and a sealing ring 14 being provided inside the connecting seat 15;

[0031] The female connector 2 is internally provided with a connector slot 21 that slidably engages with the connector column 11. Extending from the side of the connector slot 21 are a slot 23 and a countersunk hole 24 corresponding to the inner retaining ring 13 and the sealing ring 14, respectively. The end of the female connector 2 is joined and abuts against the end surface of the connecting seat 15. The male connector 1 and the female connector 2 are disposed on the sides of the first pipe clamp 3 and the second pipe clamp 4. The male connector 1 and the female connector 2 on the opposing sides of the first pipe clamp 3 and the second pipe clamp 4 are plugged and positioned for assembly. In this embodiment, the male and female connectors are made of nylon.

[0032] The edge of the inner abutment block 12 is provided with a wedge-shaped or arc-shaped mating surface, which is tightly mated with the positioning groove 22 at the inner end of the joint hole groove 21, and the inner side is abutted and positioned when the male and female connectors are plugged in, ensuring stable assembly.

[0033] The inner snap ring 13 continuously increases in diameter in the direction extending from the inner abutment block 12 to the connection seat 15, and the corresponding snap groove 23 is tightly engaged with the inner snap ring 13. This design reduces the insertion resistance stroke of the male and female connectors compared to common cylindrical plug-in structures such as plug-in and screw-in connections, making installation of the male and female connectors more labor-saving. By optimizing the pipe diameter tolerance design of the male and female connectors, they meet the design requirements of being able to rotate without wearing the pipe clamp, making them adaptable to pipelines with wider positioning requirements in actual application scenarios.

[0034] The inner and outer sides of the inner snap ring 13 and the inner side of the sealing ring 14 are sequentially provided with a wedge-shaped or arc-shaped first abutting surface 131 , a second abutting surface 132 and a third abutting surface 141 that are tightened and extended outward.

[0035] The angle between the first abutting surface 131 and the axis of the connector column 11 is 0-45°, and the angle between the second abutting surface 132 and the axis of the connector column 11 is 90-135°. The design of the male and female connectors and the chamfered angles of the steps in the insertion and extraction directions on the connectors are optimized to reduce the insertion force of the pipe clamp for easy assembly, while increasing the extraction force to prevent the two pipe clamps from falling off during use.

[0036] A wedge-shaped or arc-shaped guide surface 25 is provided on the outer edge of the countersunk hole 24 to cooperate with other internal holes and grooves to guide the air in the joint hole groove 21 to ensure a tight and stable connection.

[0037] An extension interface 16 is provided at the connection between the outer side of the connecting seat 15 and the first pipe clamp 3 or the second pipe clamp 4. Since most pipe clamps are of special shapes or arc shapes, in order to improve the connection stability, the extension interface 16 is used to increase the connection area to achieve the above design purpose.

[0038] The assembly process of the male and female joint structure for the plastic pipe clamp connecting rod of this embodiment includes: holding the pipe clamp, so that the male joint 1 and the female joint 2 are opposite and plugged into each other. At the initial stage of plugging, since there is a certain gap between the internal snap rings 13 and the slots 23 at each location, there is no resistance. When the countersunk hole 24 is about to be spliced ​​with the sealing ring 14, press hard to achieve the snap connection and positioning of the internal snap rings 13 and the slots 23, the internal abutment block 12 and the positioning groove 22, the countersunk hole 24 and the sealing ring 14, and the connection seat 15 and the female joint 2 are spliced; pull out in the opposite direction to realize the disassembly of the connecting rod structure.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
