For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components, or constituent parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components, or constituent parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0062] Existing quick-connect fittings generally consist of the following main parts: a fitting body, a sealing ring, a circlip or locking mechanism, and a connection port. The fitting body is used to connect two pipes, the sealing ring ensures the sealing performance at the connection, and the circlip or locking mechanism is used to fix the fitting to prevent it from loosening or falling off. The connection port is the part that docks with the pipe and is usually designed as an insertion structure for quick installation and disassembly. However, existing quick-connect fittings have problems such as complex structures, unreliable connections, and inability to self-lock after connection.

[0063] In view of this, the present invention provides a quick-connect fitting for connecting a first target member and a second target member, including a main body, a sealing assembly, and a lock. The main body has an installation cavity and a card slot. The sealing assembly is installed in the installation cavity; the first end of the installation cavity along its own axis forms an installation opening; the card slot communicates with the installation cavity. The front end of the lock has an open end and a guiding inclined surface. The open end of the lock is inserted into the card slot; the second end of the installation cavity along its own axis forms a connection port, and the connection port is used to connect with the second target member. Before connecting the first target member, the sealing assembly can be installed in the installation cavity, and the open end of the lock can be inserted into the card slot. When connecting the first target member, the first target member can be directly inserted into the installation cavity through the installation opening. During the process of inserting the first target member into the installation cavity, the open end of the lock can be opened by squeezing the guiding inclined surface. When the first target member is installed in place, the opened open end returns to its original state, enabling the lock to be locked with the main body, realizing the self-locking function of the lock, avoiding the lock from retracting and shaking, thereby locking the first target member in the installation cavity to prevent the first target member from disengaging from the installation cavity. At the same time, the sealing assembly seals between the first target member and the installation cavity to ensure the sealing performance. In summary, the quick-connect fitting provided by the present invention realizes the locking function of the first target member through the rebound of the lock, has a simple structure, is convenient to use, and has a reliable connection.

[0064] It can be referred to Figures 1 to 13, an embodiment of the present invention provides a quick-connect fitting 100 for connecting a first target member 200 and a second target member, including a main body 110, a sealing assembly 120, and a latch 130. The main body 110 has an installation cavity 111 and a card slot 112 therein, and the sealing assembly 120 is installed in the installation cavity 111; a first end of the installation cavity 111 along its own axis forms an installation opening 113, and the first target member 200 is inserted into the installation cavity 111 through the installation opening 113. The sealing assembly 120 is used to seal between the inner wall of the installation cavity 111 and the outer wall of the first target member 200; the card slot 112 communicates with the installation cavity 111. The front end of the latch 130 has an open end 131 and a guiding inclined surface 132. The open end 131 of the latch 130 is inserted into the card slot 112. When the first target member 200 is inserted into the installation cavity 111, the open end 131 of the latch 130 is opened by squeezing the guiding inclined surface 132. The open end 131 is configured to contract when the first target member 200 is installed in place, so as to lock the first target member 200 in the installation cavity 111; a second end of the installation cavity 111 along its own axis forms a connection port 114, and the connection port 114 is used to connect with the second target member.

[0065] Before connecting the first target member 200, the quick-connect fitting 100 provided by the embodiment of the present invention can install the sealing assembly 120 in the installation cavity 111 and insert the open end 131 of the latch 130 into the card slot 112. When connecting the first target member 200, the first target member 200 can be directly inserted into the installation cavity 111 through the installation opening 113. During the process of inserting the first target member 200 into the installation cavity 111, the open end 131 of the latch 130 can be opened by squeezing the guiding inclined surface 132. When the first target member 200 is installed in place, the opened open end 131 returns to its original state, which can lock the latch 130 with the main body 110, realizing the self-locking function of the latch 130, avoiding the backward movement and shaking of the latch 130, thereby locking the first target member 200 in the installation cavity 111 and preventing the first target member 200 from detaching from the installation cavity 111. At the same time, the sealing assembly 120 seals between the first target member 200 and the installation cavity 111 to ensure the sealing performance. In summary, the quick-connect fitting 100 provided by the present invention realizes the locking function of the first target member 200 through the rebound of the latch 130, has a simple structure, is convenient to use, and has reliable connection.

[0066] In the above embodiments, the open end 131 may have a catch 133 configured to engage with the edge of the card slot 112 when the first target member 200 is installed in place, so as to lock the first target member 200 in the installation cavity 111. It can be understood that during the process of inserting the first target member 200 into the installation cavity 111, the open end 131 of the latch 130 can be opened by squeezing the guiding inclined surface 132. When the first target member 200 is installed in place, the opened open end 131 returns to its original state. At the same time, the catch 133 can engage with the edge of the card slot 112, thereby locking the first target member 200 in the installation cavity 111.

[0067] The engagement between the catch 133 and the edge of the card slot 112 forms a reliable mechanical locking structure, greatly enhancing the fixing ability of the first target member 200 and effectively reducing the risk of connection loosening or even detachment. Moreover, the precise engagement mechanism of the catch 133 also plays an accurate limiting role in the installation position of the first target member 200. When operating personnel perform the installation operation, they can intuitively and accurately judge whether the first target member 200 is installed in place based on the fitting feedback between the catch 133 and the edge of the card slot 112. This not only improves the installation accuracy, reduces problems such as poor sealing and connection failure that may be caused by improper installation, but also helps to improve the efficiency of batch installation and reduce the defective rate during the production process. Secondly, the design of the catch 133 and the edge of the card slot 112 has good versatility. For the first target member 200 with different specifications and materials, as long as its external dimensions are within the design allowable range, the catch 133 can effectively play the locking role, enabling the quick connector 100 to be widely used in the equipment connection requirements of various fields and different working conditions, expanding its application range.

[0068] In the above embodiments, the guiding inclined surface 132 can be configured to be inclined in both the first direction and the second direction. The first target member 200 causes the opening end 131 to open by squeezing the guiding inclined surface 132 in the first direction, and causes the front end of the latch 130 to insert into the card slot 112 by squeezing the guiding inclined surface 132 in the second direction, so that the catch 133 is hooked to the edge of the card slot 112. It can be understood that when the first target member 200 is inserted into the installation cavity 111, the opening end 131 of the latch 130 can be opened by squeezing the guiding inclined surface 132 in the first direction, and at the same time, by squeezing the guiding inclined surface 132 in the second direction, the expanded latch 130 can bypass the obstacle and continue to insert into the card slot 112 (when the front end of the latch 130 is not expanded, it is blocked by the inner wall of the card slot 112 and cannot continue to insert). When the first target member 200 is installed in place, the expanded opening end 131 returns to its original state, so that the catch 133 can be hooked to the edge of the card slot 112, thereby locking the first target member 200 in the installation cavity 111. Among them, the guiding inclined surface 132 inclined in both the first direction and the second direction greatly simplifies the installation process. The operator only needs to align the first target member 200 with the installation port 113 and insert it. During the insertion process, the first target member 200 naturally squeezes the guiding inclined surface 132 in two directions. On the one hand, the squeezing in the first direction causes the opening end 131 of the latch 130 to open quickly, creating space for the first target member 200 to smoothly enter the installation cavity 111 and avoiding the situation of being blocked by the closed opening end 131. On the other hand, the squeezing in the second direction pushes the front end of the latch 130 to avoid the obstruction of the inner wall of the card slot 112 and smoothly insert into the card slot 112. Even when encountering obstacles such as slight deformation of the edge of the card slot 112 or machining tolerances, it can flexibly bypass them, ensuring a smooth installation process and greatly saving installation time and cost.

[0069] In the above embodiments, the rear end of the latch 130 can have a limiting portion 134 extending toward the front end of the latch 130. When the first target member 200 is installed in place, the limiting portion 134 abuts against the first target member 200 along the axial direction of the installation cavity 111 to lock the first target member 200 in the installation cavity 111. When the first target member 200 is installed in place, the limiting portion 134 abuts against the first target member 200 along the axial direction of the installation cavity 111, effectively restricting the axial movement of the first target member 200. Even when the device is vibrating, impacted or subjected to a certain axial tensile force during operation, the first target member 200 will not axially move, and is firmly fixed in the installation cavity 111, ensuring the stable operation of the entire connection system. Secondly, during the process of inserting the first target member 200 by the operator, when the first target member 200 touches the limiting portion 134, it can be known that it has reached the accurate position, without the need to rely on other measuring tools or repeatedly debug by experience, which not only improves the installation efficiency but also reduces the probability of problems such as poor sealing and insufficient connection strength caused by inaccurate installation positions.

[0070] In the above embodiments, in the front - rear direction of the latch 130, the guiding inclined surface 132 can be located at the rear end of the catch 133, and the limiting portion 134 can be located at the rear end of the guiding inclined surface 132. When the guiding inclined surface 132 is located at the rear end of the catch 133, when the first target member 200 presses the guiding inclined surface 132, the opening end 131 at the front end of the latch 130 can be more easily opened; when the limiting portion 134 is located at the rear end of the guiding inclined surface 132, interference between the first target member 200 and the limiting portion 134 before the first target member 200 presses the guiding inclined surface 132 can be avoided, which affects the insertion of the first target member 200 into the installation cavity 111.

[0071] In the above embodiments, in the axial direction of the installation cavity 111, the limiting portion 134 can be located on the side of the latch 130 close to the installation opening 113, and the guiding inclined surface 132 can be located on the side of the latch 130 away from the installation opening 113. With such a design, when the first target member 200 is inserted into the installation cavity 111, it can first approach the limiting portion 134 and then approach the guiding inclined surface 132. In this way, when there is interference between the first target member 200 and the limiting portion 134, the posture of the latch 130 in the card slot 112 can be conveniently adjusted, so that the first target member 200 can be smoothly inserted into the installation cavity 111.

[0072] In the above embodiments, the sealing assembly 120 can include a first sealing ring 121 and a second sealing ring 122. The inner wall of the installation cavity 111 has a first installation groove 1111, and the connection port 114 has a second installation groove 1141. The first sealing ring 121 is installed in the first installation groove 1111, and the second sealing ring 122 is installed in the second installation groove 1141. In this way, the first sealing ring 121 can seal between the first target member 200 and the quick - connect fitting 100, and the second sealing ring 122 can seal between the second target member and the quick - connect fitting 100.

[0073] In the above embodiments, the sealing assembly 120 can further include a spacer ring 123 and a third sealing ring 124. The inner wall of the installation cavity 111 further has a third installation groove 1112 and a fourth installation groove 1113. The first installation groove 1111, the third installation groove 1112, and the fourth installation groove 1113 are arranged at intervals along the axial direction of the installation cavity 111, and the third installation groove 1112 is located between the first installation groove 1111 and the fourth installation groove 1113. The spacer ring 123 is installed in the third installation groove 1112, and the third sealing ring 124 is installed in the fourth installation groove 1113. The first sealing ring 121 and the second sealing ring 122 can provide double - layer sealing between the first target member 200 and the quick - connect fitting 100, further improving the sealing effect. The spacer ring 123 can isolate between the first sealing ring 121 and the second sealing ring 122, avoiding mutual interference between the first sealing ring 121 and the second sealing ring 122.

[0074] In the above embodiments, the sealing assembly 120 may further include a safety ring 125. The inner wall of the installation cavity 111 further has a fifth installation groove 1114. The fourth installation groove 1113 is located between the fifth installation groove 1114 and the third installation groove 1112. The safety ring 125 is snap-fitted into the fifth installation groove 1114. By snap-fitting the safety ring 125 into the fifth installation groove 1114, the third sealing ring 124 can be reinforced and positioned by the safety ring 125, preventing the third sealing ring 124 from disengaging from the installation cavity 111.

[0075] In addition, an embodiment of the present invention further provides a quick-connecting component, including a first target member 200, a second target member, and the quick-connecting joint 100 in the first aspect. The quick-connecting joint 100 is used to connect the first target member 200 and the second target member; the first target member 200 is tubular, and a pressing ring 210 is provided on the outer side of the first target member 200. When the first target member 200 is inserted into the installation cavity 111, the side surface of the pressing ring 210 presses against the guiding inclined surface 132, so that the open end 131 of the latch 130 opens. A photovoltaic module includes a photovoltaic laminate and the photovoltaic frame in the first aspect. The quick-connecting joint 100 therein includes a main body 110, a sealing assembly 120, and a latch 130. The main body 110 has an installation cavity 111 and a card slot 112 therein. The sealing assembly 120 is installed in the installation cavity 111; an installation opening 113 is formed at the first end of the installation cavity 111 along its own axis. The first target member 200 is inserted into the installation cavity 111 through the installation opening 113; the card slot 112 communicates with the installation cavity 111. The front end of the latch 130 has an open end 131 and a guiding inclined surface 132. The open end 131 of the latch 130 is inserted into the card slot 112. A connection port 114 is formed at the second end of the installation cavity 111 along its own axis, and the connection port 114 is used to connect to the second target member.

[0076] Before connecting to the first target member 200, the quick-connect fitting 100 can install the sealing assembly 120 in the installation cavity 111 and insert the open end 131 of the latch 130 into the card slot 112. When connecting to the first target member 200, the first target member 200 can be directly inserted into the installation cavity 111 through the installation port 113. During the process of inserting the first target member 200 into the installation cavity 111, the pressing ring 210 can simultaneously squeeze the guiding inclined surface 132 along the first direction and the second direction, causing the open end 131 of the latch 130 to gradually open and the latch 130 to continue to insert into the card slot 112, so that the limiting portion 134 can approach the first target member 200 from one side. When the first target member 200 is installed in place, the expanded open end 131 returns to its original state, locking the latch 130 to the main body 110 to prevent the latch 130 from retracting and shaking. At the same time, the limiting portion 134 can just block on the other side of the pressing ring 210, thus locking the first target member 200 in the installation cavity 111 to prevent the first target member 200 from disengaging from the installation cavity 111. At the same time, the sealing assembly 120 seals between the first target member 200 and the installation cavity 111 to ensure tightness, improving the connection efficiency and reliability of the quick-connect assembly.
