Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quick-connect connector technology, specifically relating to a quick-connect connector with double push-lock buckles. Background Technology
[0002] In modern industry and daily life, quick-connect couplings are widely used in fluid transmission and other fields due to their advantages such as convenient connection and simple operation. However, traditional quick-connect couplings have certain limitations in terms of connection and sealing. On the one hand, existing quick-connect coupling sealing structures often use a single sealing ring or a simple sealing design. Under complex working conditions, such as high pressure, vibration, and temperature changes, the sealing effect is poor, easily leading to leakage problems. This not only wastes resources but may even cause safety accidents. On the other hand, regarding connection stability, the locking structure of some quick-connect couplings is relatively simple. During use, under external pulling or vibration, it is prone to loosening or even falling off, leading to connection failure and affecting the normal operation of equipment. Furthermore, the locking operation of existing quick-connect couplings is not convenient enough, and the installation and disassembly process is cumbersome, reducing work efficiency.

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] like Figure 1-3 As shown, a quick-connect connector with double push-button locking includes a male plug and a female plug. The male plug has a retaining ring. The female plug includes a mating section 1, a sealing section 2, and a locking section 3 connected in sequence. The sealing section 2 contains several sealing rings 4. The locking section 3 contains a double push-button locking mechanism, which includes two pressing blocks 5 and two locking blocks 6. The two pressing blocks 5 and the two locking blocks 6 are arranged opposite each other. The two sides of the locking blocks 6 are fixedly connected to the pressing blocks 5 by elastic plates 7. The two sides of the locking section 3 are provided with receiving grooves 8, which correspond to the locking blocks 6 and allow the corresponding locking blocks 6 to enter and exit. The locking section 3 has two movable openings 9, which correspond to the pressing blocks 5, and the pressing blocks 5 are located in the corresponding movable openings 9. When the male plug is inserted into the locking section 3 of the female plug, the retaining ring opens the locking blocks 6, causing the elastic plates 7 to deform, and the locking blocks 6 are pushed into the corresponding receiving grooves 8. After the male plug is in place, it forms a sealed connection with the female plug through the sealing rings 4. The locking block 6 is reset under the elastic force of the elastic plate 7, locking the retaining ring and preventing the male plug from disengaging from the female plug. When it is necessary to remove the male plug, press the two pressing blocks 5 simultaneously to push the locking block 6 into the receiving groove 8, and then remove the male plug.
[0020] Furthermore, the upper middle part of the pressing block 5 is provided with a guide groove 10, and a guide strip 11 is provided in the guide groove 10. The guide strip 11 is fixedly connected to the locking section 3. The cooperation between the guide groove 10 and the guide strip 11 allows the pressing block 5 to move in the radial direction of the female plug within the movable opening 9, preventing the pressing block 5 from getting stuck in the movable opening 9.
[0021] Furthermore, the locking block 6 is provided with a guide slope 12, and a limiting plate 13 is provided above the locking block 6, with the limiting plate 13 fixedly connected to the locking section 3. When the male plug is inserted into the female plug, the male plug acts on the guide slope 12, and the retaining ring opens the locking block 6. After the male plug is in place, the locking block 6 returns to its original position under the elastic restoring force of the elastic plate 7, locking the retaining ring and thus preventing the male plug from disengaging from the female plug.
[0022] Furthermore, a deformation groove 14 is provided at the connection between the locking block 6 and the elastic plate 7. The deformation groove 14 provides space for the deformation between the locking block 6 and the elastic plate 7, so that when the pressing block 5 is pressed, the locking block 6 can move smoothly outward into the receiving groove 8.
[0023] Furthermore, grooves 15 are provided on both sides of the movable opening 9. The grooves 15 facilitate the use of fingers to pinch and fix the female plug, making the operation of the entire quick-connect connector easier.
[0024] Furthermore, a limiting ring 16 is provided within the sealing section 2, which is engaged with the sealing section 2. A limiting platform 17 is provided within the sealing section 2, and the sealing ring 4 is located between the limiting platform 17 and the limiting ring 16. The limiting ring 16 prevents the sealing ring 4 from dislodging from the female plug during the insertion and removal of the male plug.
[0025] Furthermore, a separating ring 18 is provided between adjacent limiting rings 16. The separating ring 18 separates and limits the adjacent sealing rings 4, so that each sealing ring 4 can perform its sealing function normally.
[0026] Furthermore, the inner side of the limiting ring 16 is provided with a plurality of limiting grooves 19 evenly spaced. The part of the male plug that is inserted into the female plug is provided with limiting strips, which are respectively inserted into the limiting grooves 19. This can prevent the male plug from rotating relative to the female plug and ensure the sealing of the quick-connect connector.
[0027] Furthermore, a sealing ring 4 is installed on the connecting section 1. When the connecting section 1 is inserted into other pipes, the sealing ring 4 is used to achieve a sealed connection.
[0028] It is worth mentioning that the sealing ring and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.
[0029] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
