[0027] The present invention provides a new type of high-pressure instrument pipe valve that is quick and easy to install, such as Figures 1 to 8 As shown, the instrument pipe valve body 1 includes a clamping component 2 at both ends and the top of the instrument pipe valve body 1, butt-joint pipes 3 are inserted at both sides of the instrument pipe valve body 1, and a meter 4 is inserted at the top of the instrument pipe valve body 1, and one end of the butt-joint pipe 3 and the meter 4 are inserted into the inside of the clamping component 2. The instrument pipe valve body 1 is connected to the butt-joint pipe 3 and the meter 4 respectively through a plurality of clamping components 2, and the plurality of clamping components 2 form an integrated structure of the entire instrument pipe valve.

[0028] The clamping component 2 includes a housing 5 and a cover plate 6 that blocks the front opening of the housing 5. An inner ring edge is fixed to the rear side of the cover plate 6, and the cover plate 6 is buckled with the opening of the front side of the housing 5 using the inner ring edge. The cover plate 6 is buckled with the front side of the housing 5 using the inner ring edge of the rear side, and the cover plate 6 cooperates with the housing 5 to protect the components inside the clamping component 2 using the inner ring edge.

[0029] The butt-joint pipe 3 passes through the center of the cover plate 6, and a frame plate 7 is arranged inside the shell 5. The frame plate 7 includes a plurality of side edges, and a clamping rod 8 is embedded inside the side edge, and a plugging rod 9 is movably sleeved on the surface of the clamping rod 8, and a spring 901 is sleeved on the surface of the plugging rod 9, one end of the spring 901 is connected to the plugging rod 9, and the other end of the spring 901 is connected to the side edge, a pressure block 10 is connected to the rear end of the plugging rod 9, and a pull plate 11 is connected to the front end of the plugging rod 9, and a plugging plate 12 is fixed to the pull plate 11 on the side facing the butt-joint pipe 3 , and the surface of the butt-joint pipe 3 is provided with a concave hole 13 corresponding to the plug plate 12, the outer side surface of the pressure block 10 is provided with a chamfered surface, and the rear side wall of the shell 5 is provided with an annular inclined surface corresponding to the chamfered surface, a movable frame 14 is embedded inside the shell 5, the annular inclined surface surface of the shell 5 is provided with an inner groove corresponding to the movable frame 14, the inner side end of the movable frame 14 is provided with an inclined surface 15 corresponding to the chamfered surface, and a plurality of spring pieces 16 are fixed to the outer side end of the movable frame 14, and the outer end of the spring piece 16 is connected to the inner side of the inner groove. The butt-joint pipe 3 includes an inner pipe and an outer pipe, the concave hole 13 is located on the surface of the outer pipe, and the outer diameter of the outer pipe is larger than the outer diameter of the inner pipe, and a through groove corresponding to the inner pipe is provided at the center of the frame plate 7, and the outer diameter of the outer pipe is larger than the diameter of the through groove. After the butt-joint tube 3 uses the rear end of the inner tube to penetrate the cover plate 6, the inner tube directly penetrates the through groove at the center of the frame plate 7 and the center of the rear side of the outer shell 5, and the rear end of the inner tube is directly plugged into the end of the instrument pipe valve body 1, and continues to push the butt-joint tube 3 close to the end of the instrument pipe valve body 1. When the rear end of the outer tube of the butt-joint tube 3 contacts the outer side of the frame plate 7, the outer tube pushes the frame plate 7 to move backward inside the outer shell 5, and the backward-moving frame plate 7 uses the clamping rod 8 to drive the insertion rod 9 to move backward. At this time, the insertion rod 9 drives the pressure block 10 to move backward. Since the insertion rod 9 is sleeved on the surface of the clamping rod 8, and the center line of the insertion rod 9 is perpendicular to the center line of the clamping rod 8, and the rear side of the pull plate 11 is in contact with the front side of the frame plate 7, the pull plate 11 correspondingly limits the insertion rod 9 to prevent the insertion rod 9 from rotating on the surface of the clamping rod 8.

[0030] The backward-moving pressure block 10 gradually approaches the movable frame 14 until the inclined surface 15 at the inner end of the movable frame 14 contacts the chamfered surface of the pressure block 10, and the pressure block 10 continues to move backward. The pressure block 10 slides on the inclined surface 15 using the chamfered surface, and the moving pressure block 10 pushes the movable frame 14 away from the docking tube 3. The moving movable frame 14 cooperates with the spring sheet 16 inside the inner groove to squeeze the inner groove. The elastic force of the spring sheet 16 makes the inclined surface 15 always fit with the chamfered surface until the inner end of the movable frame 14 is separated from the chamfered surface, and the elastic force of the spring sheet 16 rebounds and makes the movable frame 14 approach the docking tube 3. At this time, the inner end of the movable frame 14 is at the front side of the pressure block 10, and the elastic force of the spring sheet 16 makes the movable frame 14 cooperate with the limited pressure block 10, thereby further limiting the frame plate 7 through the insertion rod 9 and the clamping rod 8.

[0031] When the chamfered surface of the pressure block 10 contacts the annular inclined surface of the shell 5 during the backward movement, the backward pressure block 10 gradually approaches the docking tube 3 under the limitation of the annular inclined surface, that is, the pressure block 10 uses the spring 901 on the surface of the clamping rod 8 corresponding to the insertion rod 9, and the chamfered surface of the pressure block 10 is always in contact with the annular inclined surface of the shell 5 through the elastic force of the spring 901, and the moving insertion rod 9 drives the pull plate 11 to approach the docking tube 3, and the moving pull plate 11 inserts the inner end of the plug plate 12 into the concave hole 13 on the surface of the docking tube 3. At this time, the inner end of the movable frame 14 is at the front side of the pressure block 10, and the movable frame 14 cooperates with the pressure block 10 to facilitate the pull plate 11 to use the plug plate 12 to buckle in the concave hole 13. In the process of plugging the inner tube of the docking tube 3 with the end of the instrument tube valve body 1, the docking tube 3 is quickly clamped in the inside of the clamping component 2 to prevent the docking tube 3 from detaching from the inside of the clamping component 2.

[0032] exist Figure 2 and Figure 4 In the embodiment, the inner tube surface is sleeved with a sealing sleeve, and after the inner tube of the butt-joint tube 3 passes through the frame plate 7 and the outer shell 5, the rear end of the inner tube is correspondingly plugged into the end of the instrument pipe valve body 1 through the sealing sleeve. After the inner end of the butt-joint tube 3 is plugged into the end of the instrument pipe valve body 1 by the sealing sleeve, the sealing sleeve is used to prevent water inside the instrument pipe valve body 1 from leaking out, thereby ensuring the sealing of the connection between the butt-joint tube 3 and the instrument pipe valve body 1.

[0033] exist Figure 2 and Figure 7 In the embodiment, the rear side wall of the shell 5 is fixed with a plurality of protruding rods 17 penetrating the frame plate 7, and the surface of the protruding rods 17 is sleeved with an elastic member 18, the rear side end of the elastic member 18 is connected to the rear side wall of the shell 5, and the front side end of the elastic member 18 is connected to the rear side surface of the frame plate 7, and the front side end surface of the protruding rods 17 is sleeved with a nut, and the rear side surface of the nut is in contact with the front side surface of the frame plate 7, and the elastic member 18 is in a compressed state. When the frame plate 7 moves backward, the moving frame plate 7 slides on the surfaces of the plurality of protruding rods 17, and the frame plate 7 cooperates with the shell 5 to squeeze the elastic member 18 during the movement, and the elastic force of the elastic member 18 makes the rear end of the outer tube always in contact with the front side surface of the frame plate 7, and the plurality of protruding rods 17 are used to make the frame plate 7 move smoothly inside the shell 5, and avoid the frame plate 7 from shifting during the movement.

[0034] When the inner end of the movable frame 14 is at the front side of the pressure block 10, the thrust applied to the docking tube 3 is released, the elastic force of the elastic member 18 rebounds, and the frame plate 7 uses the pressure block 10 at the rear end of the insertion rod 9 to squeeze the inner end of the movable frame 14, and the pressure of the ring bevel on the pressure block 10 makes the inner end of the insertion plate 12 correspondingly inserted into the concave hole 13 on the surface of the docking tube 3, completing the limitation of the docking tube 3 and ensuring the rapid installation of the docking tube 3.

[0035] exist Figure 5 , Figure 7 and Figure 8In the embodiment, the clamping component 2 includes an inner ring 19, which is located at the rear side of the frame plate 7. A plurality of external teeth 20 are arranged in a ring on the outer side of the circumference of the inner ring 19. A plurality of inner frames 21 are fixed on the rear side of the frame plate 7. The plurality of inner frames 21 correspond to the plurality of side edges one by one. The front side of the inner side of the circumference of the inner ring 19 is provided with an inner strip corresponding to the inner frame 21. The inner ring 19 rotates outside the plurality of inner frames 21 by means of the inner strip. A rotating rod 22 is passed through the surface of the cover plate 6. A first gear 23 is fixed at the rear end of the rotating rod 22. The first gear 23 is meshed with the external teeth 20 on the outer side of the circumference of the inner ring 19. When the rotating rod 22 is turned, the rotating rod 22 drives the first gear 23 to rotate. The rotating first gear 23 rotates the inner ring 19 by means of the plurality of external teeth 20. At this time, the inner ring 19 rotates outside the plurality of inner frames 21 by means of the inner strip. The meshing cooperation between the first gear 23 and the external teeth 20 facilitates the bidirectional rotation of the inner ring 19 inside the housing 5.

[0036] The rear side of the inner ring 19 does not contact the rear side wall of the outer shell 5. When the inner ring 19 approaches the rear side wall of the outer shell 5, the outer teeth 20 of the outer circumferential side of the inner ring 19 do not contact the ring bevel of the outer shell 5. The inner side of the pressure block 10 is provided with a clamp corresponding to the outer teeth 20. When the clamping component 2 makes the inner tube of the butt tube 3 inserted into the end of the instrument tube valve body 1, the rotating rod 22 is pulled forward, and the forward rotating rod 22 drives the first gear 23 to move forward until the first gear 23 is separated from the outer teeth 20, so as to prevent the inner ring 19 from rotating arbitrarily inside the outer shell 5 due to the rotation of the rotating rod 22.

[0037] exist Figures 3 to 8In the figure, an inner rod 24 passes through the center of the inner frame 21, a second gear 25 is fixed to the rear end of the inner rod 24, a plurality of inner teeth 26 are arranged in a ring on the inner side surface of the circumference of the inner ring 19, the second gear 25 meshes with the inner teeth 26 on the inner side surface of the circumference of the inner ring 19, a rotating plate 27 is connected to the front end of the inner rod 24, the rotating plate 27 is arranged corresponding to the pull plate 11, and a connecting strip 28 is arranged between the rotating plate 27 and the pull plate 11, one end of the connecting strip 28 is connected to the pull plate 11, and the other end of the connecting strip 28 is connected to the rotating plate 27. When the rotating rod 22 is rotated to make the first gear 23 drive the inner ring 19 to rotate, the rotating inner ring 19 uses the inner teeth 26 to rotate the second gear 25, and the rotating second gear 25 drives the rotating plate 27 to rotate by the inner rod 24. The rotating rotating plate 27 gradually reels the connecting strip 28 until the connecting strip 28 is in a taut state, and then the rotating rod 22 is continuously rotated. At this time, the rotating plate 27 continues to reel in the connecting strip 28. During the reeling process, the connecting strip 28 pulls the pulling plate 11 close to the butt joint 3. The pulling plate 11 drives the pressing block 10 to move by the insertion rod 9, and the pressing block 10 gradually approaches the butt joint 3. During the movement, the pressure block 10 gradually separates from the inner end of the movable frame 14, and the elastic force of the elastic member 18 pushes the frame plate 7 forward. At this time, the pressure block 10 gradually moves to the front side of the movable frame 14, and the chamfered surface of the pressure block 10 moves forward on the annular inclined surface of the shell 5 until the chamfered surface is separated from the annular inclined surface. At this time, the elastic force of the spring 901 pushes the insertion rod 9 to move on the clamping rod 8, that is, the pressure block 10 gradually moves away from the docking tube 3, and the moving insertion rod 9 pulls the inner end of the pull plate 11 out of the recessed hole 13. At this time, the docking tube 3 is moved from the inside of the clamping component 2, which is convenient for replacing the docking tube 3.

[0038] Working principle of the present invention:

[0039] Reference Figures 1 to 8 As shown, the cover plate 6 is buckled on the front side of the housing 5 by the inner ring edge of the rear side, and the cover plate 6 and the housing 5 cooperate with each other to protect the components inside the clamping component 2 by using the inner ring edge. After the butt-joint pipe 3 passes through the cover plate 6 by using the inner tube rear end, the inner tube directly passes through the through groove at the center of the frame plate 7 and the center of the rear side of the housing 5, and the inner tube rear end is directly plugged into the end of the instrument pipe valve body 1, and the butt-joint pipe 3 is continuously pushed close to the end of the instrument pipe valve body 1. When the outer tube rear end of the butt-joint pipe 3 contacts the outer side of the frame plate 7, the outer tube pushes the frame plate 7 to move backward inside the housing 5, and the frame plate 7 that moves backward uses the clamp rod 8 to drive the insertion rod 9 to move backward, and at this time the insertion rod 9 drives the pressure block 10 to move backward.

[0040] The backward-moving pressure block 10 gradually approaches the movable frame 14 until the inclined surface 15 at the inner end of the movable frame 14 contacts the chamfered surface of the pressure block 10, and the pressure block 10 continues to move backward. The pressure block 10 slides on the inclined surface 15 using the chamfered surface, and the moving pressure block 10 pushes the movable frame 14 away from the docking tube 3. The moving movable frame 14 cooperates with the spring sheet 16 inside the inner groove to squeeze the inner groove. The elastic force of the spring sheet 16 makes the inclined surface 15 always fit with the chamfered surface until the inner end of the movable frame 14 is separated from the chamfered surface, and the elastic force of the spring sheet 16 rebounds and makes the movable frame 14 approach the docking tube 3. At this time, the inner end of the movable frame 14 is at the front side of the pressure block 10, and the elastic force of the spring sheet 16 makes the movable frame 14 cooperate with the limited pressure block 10, thereby further limiting the frame plate 7 through the insertion rod 9 and the clamping rod 8.

[0041] When the chamfered surface of the pressure block 10 contacts the annular inclined surface of the shell 5 during the backward movement, the backward pressure block 10 gradually approaches the docking tube 3 under the limitation of the annular inclined surface, that is, the pressure block 10 uses the spring 901 on the surface of the clamping rod 8 corresponding to the insertion rod 9, and the chamfered surface of the pressure block 10 is always in contact with the annular inclined surface of the shell 5 through the elastic force of the spring 901, and the moving insertion rod 9 drives the pull plate 11 to approach the docking tube 3, and the moving pull plate 11 inserts the inner end of the plug plate 12 into the concave hole 13 on the surface of the docking tube 3. At this time, the inner end of the movable frame 14 is at the front side of the pressure block 10, and the movable frame 14 cooperates with the pressure block 10 to facilitate the pull plate 11 to use the plug plate 12 to buckle in the concave hole 13. In the process of plugging the inner tube of the docking tube 3 with the end of the instrument tube valve body 1, the docking tube 3 is quickly clamped in the inside of the clamping component 2 to prevent the docking tube 3 from detaching from the inside of the clamping component 2.

[0042] When the frame plate 7 moves backward, the frame plate 7 slides on the surface of the plurality of protruding rods 17, and the frame plate 7 cooperates with the shell 5 to squeeze the elastic member 18 during the movement. The elastic force of the elastic member 18 makes the rear end of the outer tube always fit with the front side of the frame plate 7, and the plurality of protruding rods 17 make the frame plate 7 move smoothly inside the shell 5 to prevent the frame plate 7 from shifting during the movement. When the inner end of the movable frame 14 is at the front side of the pressing block 10, the thrust applied to the butt joint pipe 3 is released, and the elastic force of the elastic member 18 rebounds. The frame plate 7 uses the pressing block 10 at the rear end of the plug rod 9 to squeeze the inner end of the movable frame 14, and the pressure of the ring bevel on the pressing block 10 makes the inner end of the plug plate 12 correspondingly plugged into the concave hole 13 on the surface of the butt joint pipe 3, completing the limitation of the butt joint pipe 3 and ensuring the rapid installation of the butt joint pipe 3. Due to its simple assembly method, there will be no "angle error" in the process of threaded connection, and it will not be stuck, and there is no need to repeatedly remove and adjust, and the installation work can be completed in one time.

[0043] By turning the rotating rod 22, the rotating rod 22 drives the first gear 23 to rotate. The rotating first gear 23 uses multiple external teeth 20 to rotate the inner ring 19. At this time, the inner ring 19 uses the inner strip to rotate on the outside of the multiple inner frames 21. The meshing cooperation between the first gear 23 and the external teeth 20 facilitates the bidirectional rotation of the inner ring 19 on the inner side of the outer shell 5.

[0044] When the rotating rod 22 is rotated to make the first gear 23 drive the inner ring 19 to rotate, the rotating inner ring 19 uses the inner teeth 26 to rotate the second gear 25, and the rotating second gear 25 drives the rotating plate 27 to rotate by the inner rod 24. The rotating rotating plate 27 gradually reels the connecting strip 28 until the connecting strip 28 is in a taut state, and then the rotating rod 22 is continuously rotated. At this time, the rotating plate 27 continues to reel in the connecting strip 28. During the reeling process, the connecting strip 28 pulls the pulling plate 11 close to the butt joint 3. The pulling plate 11 drives the pressing block 10 to move by the insertion rod 9, and the pressing block 10 gradually approaches the butt joint 3. During the movement, the pressure block 10 gradually separates from the inner end of the movable frame 14, and the elastic force of the elastic member 18 pushes the frame plate 7 forward. At this time, the pressure block 10 gradually moves to the front side of the movable frame 14, and the chamfered surface of the pressure block 10 moves forward on the annular inclined surface of the shell 5 until the chamfered surface is separated from the annular inclined surface. At this time, the elastic force of the spring 901 pushes the insertion rod 9 to move on the clamping rod 8, that is, the pressure block 10 gradually moves away from the docking tube 3, and the moving insertion rod 9 pulls the inner end of the pull plate 11 out of the recessed hole 13. At this time, the docking tube 3 is moved from the inside of the clamping component 2, which is convenient for replacing the docking tube 3.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
