DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present utility model in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0033] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] As Figures 1-5 shown, the present utility model provides a liquid-cooled two-way cut-off quick connector with an anti-reverse structure, including: a connector body 1 and a connector base 2. The connector can be a male connector or a female connector, and the male connector and the female connector are mutually supporting products produced by the applicant. Correspondingly, the connector body 1 can be a male body 11 or a female body 12. The connector body 1 is detachably connected to the connector base 2. Usually, the connector body 1 and the connector base 2 are threadedly connected, or can also be a snap connection manner such as that between the female outer sleeve 36 and the female base 22 as Figure 1 shown. 2 A two-way cut-off device is provided inside the connector body 1. Different connector bodies 1 have different two-way cut-off devices. The outer wall of the connector body 1 is connected to the inner wall of the connector base 2 through an anti-reverse device.

[0035] When the connector body 1 is a male body 11 and the connector base 2 is a male base 21, taking the threaded connection between the male body 11 and the male base 21 as an example, as Figure 2 shown, one end of the male base 21 is directly connected to the pipeline, and the other end is threadedly connected to the male body 11. At this time, the two-way cut-off device is composed of a male valve head 31 and a male spring 32 arranged inside the male body 11. The male valve head 31 is arranged inside the male body 11 and is sealed with the male body 11 through the male spring 32. The anti-reverse device is arranged on the outer wall of the male body 11;

[0036] When the connector body 1 is a female body 12 and the connector base 2 is a female base 22, taking the snap connection between the female outer sleeve 36 and the female base 22 as an example, as Figure 2 shown, the female body 12 is arranged inside the female outer sleeve 36 and is connected to the female base 22 through the female outer sleeve 36. The end of the female base 22 is directly connected to the pipeline. The female outer sleeve 36 is used to fix the female body 12 and is detachably connected to the male body 11 through a spring buckle on the female outer sleeve 36. At this time, the two-way cut-off device is composed of a female valve stem 35 arranged inside the female body 12, a female spring 34 sleeved on the female valve stem 35, and a female valve head 33 connected to the female valve stem 35 through the female spring 34. Under the action of the female spring, the female valve head 33, the female valve stem 35, and the female body 12 are sealed with each other. The anti-reverse device is arranged on the female outer sleeve 36 of the female body 12.

[0037] When the male head body 11 is connected to the female head body 12, the female head valve stem 35 pushes the male head valve head 31, thereby making the male head connector a through - passage; at the same time, the male head body 11 pushes the female head valve head 33 away from the valve stem 35, thereby making the female head connector a through - passage; thus, after the male head connector and the female head connector are connected, the pipeline can be automatically connected. When the two are disassembled, they automatically become open circuits, so that the two - way cut - off device can achieve the effects of connection and disconnection without using electronic equipment.

[0038] The working principle and beneficial effects of the above - mentioned technical solution: When the connector body 1 is connected to the connector base 2, especially when they are connected by threads, the anti - reverse device can prevent the reverse rotation and loosening of the connector body 1. Thus, when they are connected by threads, the glue - coating process can be omitted to prevent the loosening of the connector body 1, thereby optimizing the production process and avoiding the situation of glue overflow.

[0039] The anti - reverse device is composed of at least one card - joint 4 arranged on the outer wall of the connector body 1 and at least one slot component arranged on the inner wall of the connector base 2. The card - joint 4 moves unidirectionally within the slot component. The card - joint 4 is made of elastic material; the card - joint 4 is composed of a guiding surface 41, a reinforcing surface 42, and a clamping surface 43. When the card - joint 4 moves unidirectionally within the slot component, the guiding surface 41 is used to guide the card - joint 4 to move within the slot component, the clamping surface 43 is used to be clamped with the slot component, and the reinforcing surface 42 is used to connect the guiding surface 41 and the clamping surface 43. The guiding surface 41 extends spirally away from the outer wall of the connector body 1 in a direction away from the connector body 1, the clamping surface 43 extends radially away from the outer wall of the connector body 1 in a direction away from the connector body 1, the reinforcing surface 42 is arc - shaped, and both ends of the reinforcing surface 42 are respectively connected to the end of the guiding surface 41 away from the connector body 1 and the end of the clamping surface 43 away from the connector body 1. The slot component is composed of an inlet slot 5 and an outlet slot 6. One side of the inlet slot 5 is provided with a first abutting surface 51. The other side of the inlet slot 5 is connected to the outlet slot 6 through a semi - clamping end 7. A gap is reserved between the semi - clamping end 7 and the outer side wall of the connector body 1 for the card - joint 4 to enter the outlet slot 6 from the inlet slot 5;

[0040] When the card - joint 4 is located in the inlet slot 5, the clamping surface 43 abuts against the first abutting surface 51;

[0041] When the card connector 4 is located in the exit slot 6, the card-connecting surface 43 selectively abuts against the semi-card end 7. One side of the semi-card end 7 is a second abutting surface adapted to the card-connecting surface 43, and the other side is a first surface adapted to the guiding surface 41. The guiding surface 41 can abut against the first surface. When it is desired to remove the joint body 1, only need to rotate the joint body 1 forcefully, so that the first surface presses the guiding surface 41. Under the action of elasticity, the guiding surface 41 is squeezed into the gap reserved between the semi-card end 7 and the outer wall of the joint body 1. The surface of the semi-card end 7 opposite to the outer wall of the joint body 1 is a second surface, and the second surface is an arc surface adapted to the reinforcing surface 42. As the joint body 1 continues to be rotated, the reinforcing surface 42 abuts against the second surface and slides relative to it until the card connector 4 completely enters the exit slot 6. The depth of the first abutting surface 51 is adapted to the thickness of the protrusion of the card-connecting surface 43, and the depth of the second abutting surface is not greater than half of the thickness of the protrusion of the card-connecting surface 43, as Figure 4 shown. The exit slot 6 is composed of a placement slot 61 communicating with the entrance slot 5 and a moving slot 62 provided with a spiral support surface 63. The moving slot 62 communicates with the placement slot 61, and the moving slot 62 is located on the side of the placement slot 61 away from the semi-card end 7.

[0042] In the present utility model, there is no need to perform glue-dotting operation. Only need to provide the card connector 4 on the joint body 1 and provide the entrance slot 5 and the exit slot 6 on the joint base 2. According to different connection methods of the joint body 1 and the joint base 2, the opening size of the entrance slot 5 is different. For example, when the joint body 1 is screwed into the joint base 2 by thread connection, the card connector 4 does not translate along the axis of the joint body 1, but moves while rotating. Therefore, the opening of the entrance slot 5 is larger; when the joint body 1 and the joint base 2 are connected by snap connection, at this time the card connector 4 translates along the axis of the joint body 1. Therefore, the size of the entrance slot 5 only needs to be adapted to the card connector 4; when it is desired to make the card connector 4 translate along the axis of the joint body 1 without relative rotation, the thread height can be adjusted so that the threaded part of the joint body 1 can be screwed into the joint base 2 from one end of the thread of the joint base 2 and directly screwed out from the other end. No matter which connection method is selected, only need to ensure that when the card connector 4 abuts against the joint base 2, it will no longer move along the axis of the joint body 1 and can only rotate around the axis of the joint body 1, as Figure 3 shown.

[0043] In this embodiment, we take the card connector 4 translating along the axis of the joint body 1 without relative rotation as an example, as Figure 3As shown, first, the clamping joint 4 will enter the entrance groove 5 until the clamping joint 4 abuts against the inner end of the entrance groove 5. When reversed, the clamping surface 43 abuts against the first abutting surface 51, and the reinforcing surface 42 can effectively prevent the clamping surface 43 from being squeezed and deformed. When rotated forward, the guiding surface 41 will abut against the first surface, thereby also limiting the forward rotation to reduce the rotation range of the joint body 1 within the joint base 2 and prevent the joint body 1 from loosening.

[0044] When the joint body 1 is to be removed, only need to rotate the joint body 1 forcefully. At this time, the guiding surface 43 will be squeezed into the gap between the second surface and the outer wall of the joint body 1. As the rotation continues, the reinforcing surface 42 is also squeezed into the gap until the clamping joint 4 completely enters the placement groove 61. When the clamping joint 4 is located in the placement groove 61, if the joint body 1 is reversed, the clamping surface 43 will abut against the second abutting surface, thus preventing reversal again, as Figure 3 、 4 shown.

[0045] Continue to rotate the joint body 1, and the clamping joint 4 will rise along the spiral support surface 63 until it moves out of the moving groove 62, as Figure 3 shown.

[0046] Through the design of the above structure, the present utility model can not only prevent reverse rotation, but also limit forward rotation, achieving the effect that it will not come out during forward rotation without dispensing glue. When it is desired to remove it, only need to rotate the joint body 1 forcefully forward.

[0047] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0048] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model may be understood according to specific circumstances.

[0049] Although the embodiments of the present utility model have been disclosed as above, it is not limited to only the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the examples shown and described herein.
