as shown in fig. 2-4, the claw sleeve 4 is six equal parts made of metal, and can be opened and closed rapidly.
Before the screw thread sample piece 14 is sleeved, the sleeve 5 is pushed downwards, the piston slip ring 3 can be driven by the upward elastic force of the piston spring 10 to drive the main sealing ring 8 to move upwards, and the claw sleeve 4 is pushed to open when the piston slip ring 3 moves upwards (the claw sleeve 4 is opened by the contraction force of the claw sealing ring 15).
At this time, the screw-thread sample piece 14 is inserted downward, and after the screw-thread sample piece 14 contacts the main seal ring 8, the piston slip ring 3 is forced to move downward by the main seal ring 8.
At the same time, the sleeve 5 moves upwards by receiving the upward elastic force of the tail sleeve spring 11 to wrap the claw sleeves 4 (six claw sleeves 4 are wrapped at the same time).
The piston slip ring 3 moves downwards to a set position, and the claw sleeve 4 is closed. In the whole process, the plastic claw insert 1 moves along with the claw sleeve 4. At this time, the pawl sleeve 4 is closed and the pawl insert 1 is tightly gripped by the screw sample 14. The main sealing ring 8 forms a sealing ring with the screw thread sample piece 14 after being extruded, and the reliable occlusion connection is formed by the screw thread 103 on the claw tooth insert 1 and the external screw thread of the screw thread sample piece 14, so that the functions of fluid conveying, testing, quick plugging and the like of the flange pipe sample piece interface can be realized. When the claw tooth insert 1 is connected with the external thread piece, the thread 103 of the claw tooth insert can effectively prevent the external thread of a product from being scratched.
Example 3:
the following is the design of the pawl sleeve 4 of the present utility model:

The head of the claw tooth sleeve 4 is provided with a plastic claw tooth insert 1, and the claw tooth insert 1 can be conveniently installed and replaced. The metal claw tooth cover 4 body and the claw tooth insert 1 are connected by adopting a dovetail groove (T-shaped groove), and the claw tooth insert 1 is inserted into the claw tooth cover 4 body from the side face in a rotating way, so that the claw tooth insert 1 can bear the axial pressure in the working process well. To prevent the jaw insert 1 from rotating in the diametric direction, glue may be used to bond the jaw case 4 body to the jaw insert 1 or other means of attachment (e.g., small screws, fastening pins, etc. interposed therebetween). The metal claw tooth socket 4 body is used as a common part, can be produced in batch and is matched with different claw tooth inserts 1 to meet different pipe fittings of customers, thereby saving the cost and shortening the exchange period.
The claw tooth assembly is formed by the claw tooth sleeve 4 and the claw tooth insert 1, the claw tooth sleeve 4 can be made of metal materials, the claw tooth insert 1 can be made of high-strength engineering plastic inserts, and the claw tooth insert 1 is provided with a thread 103. The part of the screw thread sample piece 14 is required to be connected with the screw thread and cannot scratch the screw thread surface, such as external screw threads made of aluminum alloy and plastic materials, and the engineering plastic material claw tooth insert 1 can effectively protect the external screw thread surface of the screw thread sample piece 14 to be grabbed, so that nondestructive connection is achieved.
In particular, the material of the pawl tooth cover 4 is not limited to metal, but can be other materials suitable for practical use, and the pawl tooth insert 1 is not limited to plastic.
Example 4:
six claw tooth sleeves 4 need to bear the tensile force of hundreds of kilograms, grooves at the lower parts of the claw tooth sleeves 4 are hung on the tail sleeve 6, the outer surfaces of the claw tooth sleeves are blocked by the sleeve 5, and the elastic force provided by the claw tooth sealing rings 15 is added, so that the six claw tooth sleeves 4 have certain freedom of movement under the condition that the claw tooth sleeves 4 are not separated, and the six claw teeth can be opened and closed.
Example 5:
at a certain pressure, a first sealing section is formed between the main sealing ring 8 and the threaded sample 14 (as shown in fig. 3), while at the same time: the piston slip ring 3 and the claw insert 1 also form a second sealing section, the pressure formed by the first sealing section and the second sealing section is opposite, the pressure born by the second sealing section is larger than the pressure born by the first sealing section, namely, the upward thrust of the piston slip ring 3 is larger than the downward thrust of a sealing part (the contact position of the tail sleeve sealing ring 13 is the sealing part), along with the increase of the fluid pressure, the upward thrust of the piston slip ring 3 is also increased, and the sealing reliability of the screw thread sample 14 and the main sealing ring 8 can be ensured.
In summary, the quick connector provided by the utility model adopts the claw structure to clamp the external screw member, so that the connection and the sealing of the connector and the external screw member can be completed quickly.
