Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and particularly to a quick connection structure for pipe fittings and a water outlet device. Background Art

[0002] In the prior art, there are various connection methods between pipe fittings, which are mainly divided into fixed connections and detachable movable connections. Fixed connections include welding, bonding, or hot melting, etc. However, such connections are not conducive to disassembly. Movable connection methods include screwing, clamping, socketing, etc., which can be disassembled and assembled repeatedly and are very flexible in use. For example, they are commonly used for connecting hoses between a water supply pipe and a water outlet terminal (such as a faucet, a shower head, etc.). However, most of the current movable connection structures of pipe fittings are relatively complex, and some even require tools to operate for disassembly and assembly, having the disadvantages of difficult installation and slow disassembly and assembly. Summary of the Invention

[0003] The present invention aims to at least partly solve one of the above technical problems in the related art. For this purpose, the present invention provides a quick connection structure for pipe fittings.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] The present invention also provides a water outlet device having the above quick connection structure for pipe fittings.

[0006] According to an embodiment of the first aspect of the present invention, the quick connection structure for pipe fittings includes:

[0007] An upper joint, including an insertion head portion, the insertion head portion being tubular, and a first flange being provided on its outer peripheral wall;

[0008] A lower joint, including a socket portion and an elastic arm, a water passing cavity being formed inside the socket portion, the insertion head portion being insertable into or removable from the socket portion, at least two elastic arms being arranged along the circumferential direction of the socket portion, an acting block being provided at the upper end of the elastic arm, a guiding inclined surface being formed inside the acting block, and a first abutting plane facing downward being formed outside the acting block;

[0009] A sliding barrel, slidably sleeved on the lower joint, a third flange being provided along the circumferential direction on the inner wall of the sliding barrel, a second abutting plane being provided at the top of the third flange, and an ejecting rib being provided at the upper end inside the sliding barrel;

[0010] An elastic member, abutted between the sliding barrel and the lower joint to provide an upward elastic force to the sliding barrel;

[0011] The sliding barrel can move downward from the first position to the second position, and the elastic member is compressed during the downward movement of the sliding barrel. When the sliding barrel is in the first position, the second abutting plane abuts against the first abutting plane, and the first flange abuts against the bottom of the force-receiving block. When the sliding barrel is in the second position, the ejecting rib pushes open the force-receiving block along the guiding inclined surface, causing the elastic arm to bend outward, so that the plug head can be disengaged from the socket portion.

[0012] The pipe fitting quick-connection structure according to the embodiment of the present invention has at least the following beneficial effects:

[0013] 1. The pipe fitting quick-connection structure of the present invention can achieve rapid assembly and disassembly. When not assembled, the sliding barrel is in the first position. Under the action of the elastic member, the second abutting plane abuts against the first abutting plane, so that the sliding barrel cannot be disengaged from the lower joint. During assembly, the sliding barrel is moved to the second position. During this process, the ejecting rib abuts against the guiding inclined surface to cause the elastic arm to expand outward. The axial movement of the sliding barrel is converted into the radial expansion force of the elastic arm through the inclined surface. After the elastic arm expands outward, the plug head can be easily inserted into the socket portion. Then, the sliding barrel is pulled or directly released. The sliding barrel is reset to the first position under the action of the elastic member. During this process, the elastic arm retracts due to the loss of the extrusion force of the ejecting rib, and the force-receiving block catches the first flange, restricting the upward movement of the plug head, so that the plug head is fixedly assembled in the socket portion and will not be disengaged. The disassembly process is similar to the assembly process. The sliding barrel is moved to the second position, the elastic arm is pushed open by the ejecting rib, the force-receiving block is disengaged from the first flange, and the plug head can be disengaged from the socket portion without obstruction.

[0014] 2. The sliding barrel completes the assembly and fixation of the sliding barrel and the lower joint through its interaction with the elastic member and the elastic arm. The third flange of the sliding barrel and the first abutting plane are in plane contact, with little wear. Compared with the installation and fixation using a smooth flange and a groove, the service life of the parts of this structure is longer, increasing the durability of the quick-connection structure. Moreover, the elastic member is used to automatically reset the sliding barrel after it is released, ensuring the neatness of the product appearance and that the internal structure of the sliding barrel is not affected by the outside, enhancing the protection of the core components of the device and further increasing the durability of the quick-connection structure.

[0015] According to some embodiments of the present invention, the bottom of the force-receiving block has a third abutting plane, and the top of the first flange has a fourth abutting plane. When the sliding barrel is in the first position, the third abutting plane abuts against the fourth abutting plane.

[0016] According to some embodiments of the present invention, the outer side of the force-receiving block has an outer side surface perpendicular to the first abutting plane, and the outer side surface is located below the first abutting plane. When the sliding barrel is in the first position, the inner side surface of the third flange and the outer side surface are in clearance fit.

[0017] According to some embodiments of the present invention, the ejector rib is in a circular ring structure, located at the top of the inner side of the sliding barrel and coaxial with the sliding barrel, the ejector rib is connected to the sliding barrel by a connecting rib, the lower edge of the ejector rib is smooth, and in the process of the sliding barrel moving from the first position to the second position, the lower edge presses against the guide slope, causing the force block to move outward.

[0018] According to some embodiments of the present invention, the outer circumferential wall of the plug portion is further provided with a smooth fourth flange, wherein the fourth flange is located above the first flange, and when the sliding barrel is located at the first position, the fourth flange is opposite to the guide inclined surface, and the inner side of the ejector rib has a first inner circumferential wall and a second inner circumferential wall, and the first inner circumferential wall is located above the second inner circumferential wall, and the diameter of the first inner circumferential wall is larger than the diameter of the second inner circumferential wall, and the diameter of the fourth flange is larger than the diameter of the second inner circumferential wall and smaller than the diameter of the first inner circumferential wall, and during the process of the sliding barrel moving from the first position to the second position, the second inner circumferential wall can be pushed outward by the fourth flange to cause the ejector rib to bend outward to open the elastic arm.

[0019] According to some embodiments of the present invention, the outer peripheral wall of the socket portion is provided with a second flange, the elastic member is a spring, the spring is sleeved on the socket portion, the lower end of the spring abuts against the second flange, and the upper end abuts against the third flange.

[0020] According to some embodiments of the present invention, the travel L1 from the first position to the second position is smaller than the distance L2 from the uppermost end of the force block to the uppermost end of the sliding barrel when the sliding barrel is in the first position.

[0021] According to some embodiments of the present invention, when the sliding barrel is in the first position, the lowermost end of the sliding barrel is flush with the lowermost end of the second flange.

[0022] According to some embodiments of the present invention, a sealing ring is sleeved on the outer peripheral wall of the plug part, and when the plug part is inserted into the socket part, the sealing ring can seal the gap between the plug part and the socket part.

[0023] The water outlet device according to the second aspect of the embodiment of the present invention includes the pipe quick-connect structure.

[0024] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Invention

[0036] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] Refer to Figures 1-9, a quick-connection structure for pipe fittings, comprising:

[0038] An upper joint 100, including an insertion head 300. The insertion head 300 is tubular, and a first flange 310 is provided on its outer peripheral wall;

[0039] A lower joint 400, including a socket part 600 and elastic arms 700. A water passing cavity 610 is formed inside the socket part 600. The insertion head 300 can be inserted into or withdrawn from the socket part 600. After the insertion head 300 is inserted into the socket part 600, the upper joint 100 communicates with the lower joint 400. There are at least two elastic arms 700 arranged along the circumferential direction of the socket part 600. The upper end of the elastic arm 700 has a force-receiving block 710. A guiding inclined surface 711 is formed inside the force-receiving block 710, and a first abutting plane 712 facing downward is formed on the outer side of the force-receiving block 710;

[0040] A sliding barrel 800, which is sleeve-shaped and slidably sleeved on the lower joint 400. A third flange 810 is provided along the circumferential direction on the inner wall of the sliding barrel 800. The top of the third flange 810 has a second abutting plane 811. The socket part 600 and the elastic arms 700 are located inside the sliding barrel 800. An ejecting rib 820 is provided at the upper end inside the sliding barrel 800;

[0041] An elastic member 900, which abuts between the sliding barrel 800 and the lower joint 400 to provide an upward elastic force to the sliding barrel 800;

[0042] The sliding barrel 800 can move downward from a first position to a second position, and the elastic member 900 is compressed during the downward movement of the sliding barrel 800. When the sliding barrel 800 is in the first position, the second abutting plane 811 abuts against the first abutting plane 712, and the first flange 310 abuts against the bottom of the force-receiving block 710. When the sliding barrel 800 is in the second position, the ejecting rib 820 pushes open the force-receiving block 710 along the guiding inclined surface 711 to bend the elastic arms 700 outward, so that the insertion head 300 can be withdrawn from the socket part 600.

[0043] Working principle: When not assembled, the sliding barrel 800 is in the first position. Under the action of the elastic member 900, the second abutting plane 811 abuts against the first abutting plane 712, so that the sliding barrel 800 cannot be disengaged from the lower joint 400. During assembly, the sliding barrel 800 is pulled to the second position. During this process, the ejecting rib 820 abuts against the guiding inclined surface 711 to cause the elastic arm 700 to expand outward. The axial movement of the sliding barrel 800 is converted into the radial expansion force of the elastic arm 700 through the inclined surface. After the elastic arm 700 expands outward, the insertion head 300 can be easily inserted into the socket portion 600. Subsequently, the sliding barrel 800 is pulled or directly released. The sliding barrel 800 returns to the first position under the action of the elastic member 900. During this process, the elastic arm 700 retracts due to the loss of the extrusion force of the ejecting rib 820, and the force receiving block 710 catches the first flange 310, restricting the upward movement of the insertion head 300, so that the insertion head 300 is fixedly assembled in the socket portion 600 and will not come out. The disassembly process is similar to the assembly process. The sliding barrel 800 is moved to the second position, the elastic arm 700 is pushed open by the ejecting rib 820, the force receiving block 710 is disengaged from the first flange 310, the insertion head 300 can be disengaged from the socket portion 600 without hindrance, and finally the sliding barrel 800 is released to return it to the first position.

[0044] In some embodiments of the present invention, the upper joint 100 further includes a first pipe fitting connecting portion 200, the first pipe fitting connecting portion 200 is located above the insertion head 300, the lower joint 400 further includes a second pipe fitting connecting portion 500, and the second pipe fitting connecting portion 500 is located below the socket portion 600. Both the first pipe fitting connecting portion 200 and the second pipe fitting connecting portion 500 are hollow structures for connecting with external pipe fittings. It can be understood that the upper joint 100 and the pipe fitting can be an integral structure or a split structure. If it is an integral structure, the upper joint 100 does not have the first pipe fitting connecting portion 200, and the insertion head 300 is directly integrally formed with the pipe fitting. If it is a split structure, the upper joint 100 can be provided with the first pipe fitting connecting portion 200 for connecting with the pipe fitting.

[0045] In some embodiments of the present invention, the bottom of the force receiving block 710 has a third abutting plane 713, and the top of the first flange 310 has a fourth abutting plane 311. When the sliding barrel 800 is in the first position, the third abutting plane 713 abuts against the fourth abutting plane 311. The force receiving block 710 and the first flange 310 are in plane contact, which is not easy to form a guide and slip off, reducing the risk of disengagement and increasing the firmness of the quick connection structure.

[0046] In some embodiments of the present invention, the outer side of the force block 710 has an outer side surface 714 perpendicular to the first abutting plane 712, and the outer side surface 714 is located below the first abutting plane 712. When the sliding barrel 800 is located at the first position, the inner side surface 812 of the third flange 810 is in clearance fit with the outer side surface 714. When the upper connector 100 is subjected to a force to disengage from the lower connector 400 (force such as hand pulling or water flow impact), the fourth abutting plane 311 will drive the third abutting plane 713 to move, so that the force block 710 is forced to expand outward, but because the inner side surface 812 of the third flange 810 greatly limits the outward expansion distance of the outer side surface 714 of the force block 710, the degree of expansion of the force block 710 cannot meet the fourth abutting plane 311 and the third abutting plane 713 completely separated, and then the plug part 300 still cannot be separated from the socket part 600, which greatly improves the assembly firmness of the quick connection structure.

[0047] In some embodiments of the present invention, the ejector rib 820 is in a toroidal structure, located at the top of the inner side of the slide barrel 800 and coaxial with the slide barrel 800, the ejector rib 820 and the slide barrel 800 are connected by a connecting rib 830, the lower edge 821 of the ejector rib 820 is in a rounded shape, and when the slide barrel 800 moves from the first position to the second position, the lower edge 821 abuts against the guide inclined surface 711, so that the force block 710 moves outward. The ejector rib 820 is in a toroidal structure and coaxial with the slide barrel 800, ensuring that the elastic arms 700 uniformly distributed along the circumference bend outward synchronously when subjected to force, and the toroidal structure can apply equal radial force to the force block 710 of each elastic arm 700, avoiding jamming or unilateral excessive deformation caused by local uneven force, and ensuring that the elastic arms 700 are opened synchronously when the plug part 300 is disengaged, and the action is reliable. The lower edge 821 of the ejector rib 820 is rounded and smooth, and when matched with the guide inclined surface 711, the sliding friction can be reduced, so that the ejector rib 820 can slide smoothly along the inclined surface.

[0048] In some embodiments of the present invention, a smooth fourth flange 320 is further provided on the outer peripheral wall of the plug head 300. The fourth flange 320 is located above the first flange 310. When the sliding barrel 800 is in the first position, the fourth flange 320 faces the guiding inclined surface 711. The inner side of the ejecting rib 820 has a first inner peripheral wall 822 and a second inner peripheral wall 823. The first inner peripheral wall 822 is located above the second inner peripheral wall 823. The diameter of the first inner peripheral wall 822 is greater than that of the second inner peripheral wall 823. The diameter of the fourth flange 320 is greater than that of the second inner peripheral wall 823 and less than that of the first inner peripheral wall 822. During the process of the sliding barrel 800 moving from the first position to the second position, the second inner peripheral wall 823 can be subjected to an outward thrust from the fourth flange 320, causing the ejecting rib 820 to bend outward to expand the elastic arm 700. During the process of pulling the sliding barrel 800 from the first position to the second position, the second inner peripheral wall 823 first contacts the fourth flange 320 and receives an outward supporting force from the fourth flange 320. When the lower edge 821 of the ejecting rib 820 contacts the guiding inclined surface 711, due to the outward supporting force received by the second inner peripheral wall 823 from the fourth flange 320, the elastic arm 700 expands outward. When it expands until the third abutting plane 713 completely disengages from the fourth abutting plane 311, the plug head 300 can be withdrawn unobstructed. Moreover, the diameter of the first inner peripheral wall 822 is greater than both the diameter of the second inner peripheral wall 823 and the diameter of the fourth flange 320. Therefore, when loosening, the plug head 300 is easier to withdraw, making the disconnection between the upper joint 100 and the lower joint 400 simpler and faster.

[0049] In some embodiments of the present invention, a second flange 620 is provided on the outer peripheral wall of the socket part 600. The elastic member 900 is a spring. The spring is sleeved on the socket part 600. The lower end of the spring abuts against the second flange 620, and the upper end abuts against the third flange 810. The spring is sleeved on the socket part 600 and is coaxial with the sliding barrel 800 and the socket part 600, ensuring that the elastic force is transmitted linearly along the axis and avoiding skewing or jamming of the sliding barrel 800 caused by off-axis loading. The spring is sleeved on the outer periphery of the socket part 600 and is arranged using the annular gap between the sliding barrel 800 and the socket part 600, without the need for additional axial or radial space, meeting the requirements of miniaturization and lightweight of the pipe fitting quick-connection structure. The spring is made of metal materials (such as stainless steel, spring steel). The metal spring has better tolerance to temperature, humidity, and corrosive media than the non-metal elastic member 900 and is suitable for the complex environments that may be encountered in pipe fitting connections, such as in the hot water pipes required for a shower head. It can be understood that the upper end of the spring does not necessarily abut against the third flange 810. Another flange can also be provided inside the sliding barrel 800 for the upper end of the spring to abut against, as long as the spring can provide an upward elastic force to the sliding barrel 800.

[0050] In some embodiments of the present invention, the stroke L1 from the first position to the second position is less than the distance L2 from the uppermost end of the force-receiving block 710 to the uppermost end of the sliding barrel 800 when the sliding barrel 800 is in the first position. When the sliding barrel 800 is pulled down to the second position, the force-receiving block 710 will not protrude outside the sliding barrel 800, ensuring that the structure of the lower joint 400 is always wrapped by the sliding barrel 800 throughout the process of disassembly and installation, and guaranteeing the integrity of the appearance of the quick-connection structure.

[0051] In some embodiments of the present invention, when the sliding barrel 800 is in the first position, the lowermost end of the sliding barrel 800 is flush with the lowermost end of the second flange 620. The flush design enables the sliding barrel 800 to completely wrap the internal parts, optimizes the spatial layout, reduces interference and impurity retention, and guarantees the integrity of the appearance.

[0052] In some embodiments of the present invention, a sealing ring 330 is sleeved on the outer peripheral wall of the plug head 300. When the plug head 300 is inserted into the socket part 600, the sealing ring 330 can block the gap between the plug head 300 and the socket part 600. There is a tiny gap on the mating surface between the plug head 300 and the socket part 600, and the sealing ring 330 fills the gap through elastic deformation to prevent water from leaking from the connection.

[0053] A water outlet device includes the above-mentioned pipe fitting quick-connection structure. The water outlet device can be products such as a faucet, a spray gun, a shower head, etc. Taking the shower head as an example, the shower head includes a handle 1000 and a hose 1100. The handle 1000 is connected to the first pipe fitting connection part 200, and the hose 1100 is connected to the second pipe fitting connection part 500.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
