Description

Technical Field

[0001] This utility model relates to the field of connecting component technology, specifically to quick-connect couplings. Background Technology

[0002] Currently, most quick-connect couplings use a single locking mechanism. Under the influence of external forces such as vibration or accidental pulling, this locking mechanism may fail momentarily, causing the coupling to detach unexpectedly. Furthermore, because the locking mechanism needs to be located entirely outside the coupling for easy operation, its axial or radial dimensions are too large, limiting its application in confined spaces.

In the locked position, the locking member can maintain the inner cavity contraction to lock the second connecting section in the inner cavity. In the unlocked position, the locking member moves away from the first connecting section. The main drive structure includes a detachably connected main drive component and a mating component. The main drive component is movably disposed on the first connecting section and has a mating position and a disengaged position. The main drive component is subjected to force relative to the first connecting section to move from the mating position to the disengaged position to release the mating between the main drive component and the mating component. The drive structure includes a driven member and an elastic member connected together. The driven member abuts against the inner wall of the cavity, and the elastic member is capable of deforming as the cavity contracts. When the locking member is in the locked position, the main driving member is in the engaged position, which is used to constrain the opening of the inner cavity and to deform the elastic member to accumulate the rebound force that drives the driving member to move. When the locking member is in the unlocked position, an external force is applied to the main drive member to put it in the separated position, thereby releasing the constraint on the inner cavity, and the elastic member restores its deformation to move the secondary drive member to allow the inner cavity to open.

[0005] Furthermore, the inner wall of the inner cavity is provided with a first limiting surface, and the second connecting section is provided with a second limiting surface. The second limiting surface can extend into the inner cavity and abut against the first limiting surface to prevent the second limiting surface from dislodging from the inner cavity. and / or The inner wall of the inner cavity and one of the second connecting sections are provided with a limiting boss and the other is provided with a limiting groove, and the limiting boss can be embedded in the limiting groove.

[0006] Furthermore, the first connecting segment and the locking member are respectively provided with a third limiting surface and a fourth limiting surface. When the locking member is in the locked position, the third limiting surface abuts against the fourth limiting surface. and / or The locking member is movably provided with a positioning block, which is detachably connected to the second connecting section and is used to hold the locking member in the locked position.

[0007] Furthermore, the second connecting segment is fitted with a first spring, one end of which is connected to the second mounting end, and the other end of which is connected to the locking member.

[0008] Furthermore, the first connecting segment includes a first housing and a second housing, the first housing being movable relative to the second housing, with the inner cavity formed between the two.

[0009] Furthermore, the main driving component includes: a pressing rod, a stop block, and a second spring. The pressing rod is movably disposed in the second housing and can be linked with the stop block to compress the second spring to move from the mating position to the disengaged position. The stop block is provided with a stop groove. The mating component includes a connecting block and a hook. The connecting block is disposed on the first housing and connected to the hook. At the mating position, the hook can be hung on the stop groove. At the disengaged position, the hook is separated from the stop groove.

[0010] Furthermore, the drive component includes a push rod and a positioning rod, which are respectively disposed in the first housing and the second housing, and are connected by the elastic element.

[0011] Furthermore, the push rod is slidably sleeved outside the positioning rod, and the elastic element is hidden inside the push rod.

[0012] Furthermore, the elastic element is a third spring.

[0013] Furthermore, the first housing and the second housing are connected by a splicing structure, the splicing structure including at least one protrusion and at least one notch, the protrusion extending spirally, and the notch for accommodating the protrusion.

[0014] Compared with the prior art, this utility model has the following advantages: the inner cavity can open or contract under the action of external force to release or clamp the second connecting section inside, forming a quick-release and quick-install plug; furthermore, the contraction of the inner cavity by the locking member forms a first locking safety, and the main drive structure forms a second locking safety. Under the double locking safety, active restraint can be formed to avoid the connector from accidentally disengaging due to uncertain external forces; at the same time, when the double locking safety is released, the inner cavity can automatically open under the action of the drive structure to facilitate the quick removal of the second connecting section inside; most of the components in this connector are integrated inside the connecting section, and the moving stroke of each movable component is small, reducing its operating space, thereby making the connector structure more compact and suitable for narrow spaces.

Detailed Implementation

[0017] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figures 1-3 As shown, the quick-connector includes: a first connector, a second connector, a locking element 6, a main drive structure, and a slave drive structure; The first connector has a first mounting end 1, a first connecting segment 2 and an inner cavity 203 defined by the first connecting segment 2, the inner cavity 203 being configured to open or contract under external force; The second connector has a second mounting end 3 and a second connecting segment 4, wherein the first mounting end 1 and the second mounting end 3 both have mounting holes 5, and a portion of the second connecting segment 4 can extend into the inner cavity 203; The locking member 6 is movably disposed on the second connecting section 4 and has a locked position and an unlocked position. In the locked position, the locking member 6 can maintain the inner cavity 203 contraction to lock the second connecting section 4 in the inner cavity 203. In the unlocked position, the locking member 6 moves away from the first connecting section 2. The main drive structure includes a detachable main drive component 7 and a mating component 8. The main drive component 7 is movably disposed on the first connecting section 2 and has a mating position and a disengaged position. When the main drive component 7 is subjected to force relative to the first connecting section 2, it moves from the mating position to the disengaged position to release the mating between the main drive component 7 and the mating component 8. The driven structure includes a driven member 9 and an elastic member 10 connected to each other. The driven member 9 abuts against the inner wall of the inner cavity 203, and the elastic member 10 can deform as the inner cavity 203 contracts. When the locking member 6 is in the locked position, the main driving member 7 is in the engaged position, which is used to constrain the inner cavity 203 from opening and to deform the elastic member 10 to accumulate the rebound force that drives the driving member 9 to move. When the locking member 6 is in the unlocked position, an external force is applied to the main drive member 7 to put it in the separated position, thereby releasing the constraint on the inner cavity 203, and the elastic member 10 restores its deformation to move the secondary drive member 9 to allow the inner cavity 203 to open.

[0018] Specifically, in this embodiment of the invention, the first connector and the second connector are detachable. To enable quick assembly and disassembly, the first and second connectors each have a first connecting segment 2 and a second connecting segment 4, which are generally cylindrical in shape. The first connecting segment 2 has an inner cavity 203, into which a portion of the second connecting segment 4 can be inserted. Furthermore, the first and second connectors also have a first mounting end 1 and a second mounting end 3, both of which are provided with mounting holes 5 to facilitate the installation of external components. For example, when the connector is used to connect a cable and a hook, the component can be installed into the corresponding mounting hole 5; or when the connector is used to connect two rods, the two rods can be installed into the corresponding mounting holes 5 respectively. Of course, the connector can also be used as other connecting components, which are not limited here.

[0019] Furthermore, in order to confine part of the second connecting segment 4 within the inner cavity 203 to form a high-strength joint, or to release the second connecting segment 4 to form a separable joint, the inner cavity 203 can contract inward or expand outward under external force, thus playing a constricting role when contracting and a releasing role when expanding. Simultaneously, when the inner cavity 203 is in a contracted state, a double locking safety is provided to prevent the second connecting segment 4 from automatically disengaging due to uncertain external forces or vibrations.

[0020] Specifically, the first locking mechanism is a locking element 6, which can move back and forth at the second connecting section 4 located outside the inner cavity 203 under the action of external force, thereby moving closer to or away from the inner cavity 203, so that the locking element 6 has a locked position and an unlocked position. When the locking element 6 is in the locked position, it can cause the inner cavity 203 to contract and lock the second connecting section 4 inside the inner cavity 203, thus acting as the first locking mechanism; conversely, when the locking element 6 is in the unlocked position, the locking element 6 moves away from the inner cavity 203 and moves away from the first connecting section 2, and the locking engagement between the two is released, thus releasing the inner cavity 203.

[0021] The second locking mechanism is a main drive structure, which includes a main drive component 7 and a mating component 8. Similarly, the main drive component 7 can move relative to the first connecting section 2 under external force, allowing it to have a mating position and a disengaged position. When there is no external force, the main drive component 7 is in the mating position, connecting with the mating component 8 to constrain the opening of the inner cavity 203. Conversely, when an external force acts on the main drive component 7, causing it to move from the mating position to the disengaged position, the main drive component 7 and the mating component 8 are separated, releasing the constraint on the inner cavity 203 and allowing the inner cavity 203 to open.

[0022] Therefore, through the cooperation of the locking component 6 and the main drive structure, the two can be controlled independently and can work together to form a double locking safety, preventing accidental disengagement of the joint. That is, the locking component 6 maintains the contraction of the inner cavity 203 in the locked position; and, in the locked state, the main drive component 7 is in the mating position to actively restrain the inner cavity 203 and prevent it from opening; thus, as long as the mating connection between the main drive component 7 and the mating component 8 is not broken, the inner cavity 203 cannot expand, and the locking cannot be released, eliminating accidental disengagement caused by external forces such as vibration and pulling, and achieving double-safety locking.

[0023] On the other hand, a driven structure is also provided within the inner cavity 203. This driven structure includes a driven member 9 and an elastic member 10. The driven member 9 can abut against the inner wall of the inner cavity 203. When the inner cavity 203 is in a contracted state, the driven member 9 can deform the elastic member 10, giving it a tendency to push the driven member 9 outward. When the double locking safety is released, the elastic member 10 can gradually recover its deformation, and in this process, the driven member 9 can push the inner cavity 203 outward, causing it to open. The opened inner cavity 203 can then disengage the second connecting section 4, enabling quick disassembly of the second connecting section 4. During operation, moving the locking member 6 to the unlocked position requires only a simple unlocking force applied to the main driving member 7, moving it to the separation position. The constraint is released, and the pre-compressed elastic member 10's stored capacity is instantly released, actively and forcibly opening the inner cavity 203 through the driven member 9. In this process, only the main drive component 7 needs to be operated, and automatic separation is completed with a single action; and rapid separation is achieved by relying on the deformation force of the built-in elastic component 10, which can overcome adhesion and residual pressure, making it easy to operate and allowing for quick installation and disassembly. Of course, the main drive structure and the driven structure are highly integrated into the inner cavity 203 of the first connecting section 2, and the unlocking operation only needs to be performed at one end of the connector, requiring little operating space. The entire connector structure is compact, with no exposed components, making it easily adaptable to narrow spaces.

[0024] This embodiment forms a double locking safety by setting the locking component 6 and the main drive structure, which has strong anti-interference ability and can form a high-strength joint, improving its tensile strength and safety. At the same time, the cooperation between the main drive structure and the slave drive structure can quickly open the inner cavity 203 under the action of external force, which is faster and more convenient. Furthermore, most of the components are integrated in the inner cavity 203, making the structure more compact and flexible for different scenarios.

[0025] like Figure 2As shown, in one embodiment, the inner wall of the inner cavity 203 is provided with a first limiting surface 204, and the second connecting segment 4 is provided with a second limiting surface 401. The second limiting surface 401 can extend into the inner cavity 203 and abut against the first limiting surface 204 to prevent the second limiting surface 401 from dislodging from the inner cavity 203. Specifically, when the inner cavity 203 contracts, in order to prevent the second connecting segment 4 from automatically dislodging from the inner cavity 203, this embodiment uses the first limiting surface 204 and the second limiting surface 401 to abut against each other to prevent the second connecting segment 4 from automatically dislodging from the inner cavity 203. In this embodiment, the inner wall of the inner cavity 203 is provided with a stepped surface, and the first limiting surface 204 is formed at the stepped surface; at the same time, the end of the second connecting segment 4 is provided with a conical head, which can extend into the inner cavity 203, and the second limiting surface 401 is provided at the conical head; thus, when the inner cavity 203 contracts, the first limiting surface 204 and the second limiting surface 401 can abut against each other to form a first layer of limiting structure, so that external force cannot pull out the second connecting segment 4.

[0026] In this embodiment, to further improve the connection strength between the first connecting segment 2 and the second connecting segment 4, a limiting boss 205 is provided on the inner wall of the inner cavity 203 and on one of the second connecting segments 4, and a limiting groove 402 is provided on the other. The limiting boss 205 can be embedded in the limiting groove 402. Thus, the contracted inner cavity 203 allows the limiting boss 205 to be embedded in the limiting groove 402, forming a second layer of limiting structure. Under the action of the double-layer limiting structure, the connection strength between the two connecting segments can be improved, further preventing the joint from automatically detaching. Conversely, when the inner cavity 203 expands, the second connecting segment 4 can be removed from the inner cavity 203, and the first limiting surface 204, the second limiting surface 401, the limiting boss 205, and the limiting groove 402 become ineffective.

[0027] like Figure 2 , Figure 3 As shown, in one embodiment, the first connecting segment 2 and the locking member 6 are respectively provided with a third limiting surface 206 and a fourth limiting surface 601. When the locking member 6 is in the locked position, the third limiting surface 206 abuts against the fourth limiting surface 601. Specifically, since the locking member 6 is movable, in order to determine the position of the locking member 6, this embodiment provides a third limiting surface 206 and a fourth limiting surface 601. When the third limiting surface 206 abuts against the fourth limiting surface 601, the locking member 6 is in the locked position.

[0028] like Figure 4 , Figure 5As shown, since the locking member 6 can move back and forth along the axial direction of the second connecting section 4, and the second connecting section 4 has a smooth outer surface, on the one hand, the locking member 6 is restricted to the locked position, and on the other hand, the locking member 6 is prevented from axial movement and radial rotation. In this embodiment, the locking member 6 is movably provided with a positioning block 11, which is detachably connected to the second connecting section 4, and is used to hold the locking member 6 in the locked position. Specifically, an opening is provided at the locking member 6, and a rotating shaft is provided in the opening. The positioning block 11 can rotate relative to the rotating shaft, so that the positioning block 11 can be engaged with the second connecting section 4 or separated from the second connecting section 4. The locked member 6 and the second connecting section 4 are engaged together to form a whole, preventing the locking member 6 from moving or rotating relative to the second connecting section 4; conversely, releasing the locking member 6 can release the engagement between the two, so that the locking member 6 can move relative to the inner cavity 203 under the action of external force. Of course, the above-mentioned engagement connection can be replaced with other connection methods, such as bolt connection.

[0029] like Figure 4 , Figure 5 As shown, in one embodiment, the second connecting segment 4 is fitted with a first spring 12, one end of which is connected to the second mounting end 3, and the other end is connected to the locking member 6. Specifically, in order to enable the locking member 6 to move back and forth along the axial direction of the second connecting segment 4 and to automatically return to the locked position, this embodiment uses a first spring 12 fitted over the second connecting segment 4, which connects the second mounting segment and the locking member 6. Thus, when the locking member 6 is pulled to the unlocked position, the first spring 12 is compressed. After the locking member 6 is released, the first spring 12 resets and pushes the locking member 6 to the locked position, facilitating operation.

[0030] like Figures 6-8 As shown, in one embodiment, the first connecting segment 2 includes a first housing 201 and a second housing 202. The first housing 201 is movable relative to the second housing 202, and the inner cavity 203 is formed between them. Specifically, in order to enable the inner cavity 203 to contract inward or expand outward, this embodiment defines the first connecting segment 2 as including a first housing 201 and a second housing 202 arranged opposite to each other, with the inner cavity 203 formed between the first housing 201 and the second housing 202, and the first housing 201 being movable relative to the second housing 202. Then, when an external force is applied to the first housing 201, the first housing 201 can move towards or away from the second housing 202 to contract or expand the inner cavity 203.

[0031] like Figures 7-10As shown, in one embodiment, the main driving component 7 includes: a pressing rod 701, a stop block 702, and a second spring 703. The pressing rod 701 is movably disposed on the second housing 202 and can be linked with the stop block 702 to compress the second spring 703 to move from the mating position to the disengaged position. The stop block 702 is provided with a stop groove 704. The mating component 8 includes: a connecting block 801 and a hook 802. The connecting block 801 is disposed on the first housing 201 and connected to the hook 802. In the mating position, the hook 802 can be hung on the stop groove 704. In the disengaged position, the hook 802 is separated from the stop groove 704. Specifically, to constrain the movement of the first housing 201, this embodiment defines the main driving component 7 as including a pressing rod 701, a stop block 702, and a second spring 703, and the mating component 8 as including a connecting block 801 and a hook 802. Thus, when an external force is applied to the pressing rod 701, causing it to move downwards, the stop block 702, located at the lower part of the pressing rod 701, compresses the spring as it moves downwards. During this process, the main driving component 7 moves from the mating position to the disengaged position, causing the hook 802 to disengage from the stop groove 704 at the stop block 702, releasing the constraint on the first housing 201. Conversely, when the main driving component 7 moves from the disengaged position to the mating position, the hook 802 can be reattached to the stop groove 704 to constrain the outward movement of the first housing 201. Of course, as... Figure 9 and Figure 10 As shown, the connecting block 801 is provided with a contact surface that can be adapted to the inner wall of the first housing 201 to increase the connection area with it. And / or, a guide rod is provided in the second housing 202, and the second spring 703 is sleeved on the guide rod so that the stop block 702 can compress the second spring 703 downward when it moves, and the second spring 703 can lift the stop block 702 upward when it returns to its original position.

[0032] like Figure 7 , Figure 8 , Figure 11 and Figure 12As shown, in one embodiment, the driven member 9 includes a push rod 901 and a positioning rod 902. The push rod 901 and the positioning rod 902 are respectively disposed on the first housing 201 and the second housing 202, and are connected by the elastic member 10. Specifically, in the unlocked state and when the main driven member 7 is in the separated position, in order to enable the first housing 201 to move relative to the second housing 202 and open the inner cavity 203, this embodiment defines the driven member 9 as including a push rod 901 and a positioning rod 902. The push rod 901 always abuts against the first housing 201, the positioning rod 902 is fixed at the second housing 202, and the elastic member 10 connects the push rod 901 and the positioning rod 902. Thus, during the process of the elastic member 10 restoring its deformation, the push rod 901 can be used to move the first housing 201 away from the second housing 202, thereby opening the inner cavity 203. Conversely, when the first housing 201 moves toward the second housing 202, the elastic element 10 is compressed by the push rod 901, and when the inner cavity 203 is in a contracted state, the elastic element 10 is always kept in a compressed state because it is locked by the main drive structure and the locking element 6, so that the elastic element 10 has the tendency to push the push rod 901 outward.

[0033] Furthermore, such as Figure 11 , Figure 12 As shown, in one embodiment, the push rod 901 is slidably sleeved outside the positioning rod 902, and the elastic element 10 is hidden inside the push rod 901. To constrain the movement direction of the push rod 901 and enable the elastic element 10 to act as the driving force for the push rod 901, this embodiment inserts the positioning rod 902 into the push rod 901, creating a gap between them, allowing the push rod 901 to slide relative to the positioning rod 902. At this time, the positioning rod 902 also serves as a guide. Simultaneously, hiding the elastic element 10 inside the push rod 901 allows for precise compression of the elastic element 10, enabling it to push the push rod 901 outwards; it also makes the structure more compact and easier to use in confined spaces. Preferably, the elastic element 10 is a third spring.

[0034] like Figure 13 , Figure 14As shown, in one embodiment, the first housing 201 and the second housing 202 are connected by a splicing structure, which includes at least one protrusion 13 and at least one notch 14. The protrusion 13 extends spirally, and the notch 14 is used to accommodate the protrusion 13. Specifically, in order to improve the connection strength between the first housing 201 and the second housing 202, this embodiment provides a protrusion 13 in the first housing 201 and a notch 14 in the second housing 202. The threaded protrusion 13 is formed on the end face of the first housing 201, and the notch 14 can be used to accommodate the protrusion 13, thereby improving the overall pull-out resistance of the first connecting segment 2. Of course, the protrusion 13 and the notch 14 can also be set in two sets, which can further improve the structural strength of the first connecting segment 2.
