Description

Technical Field

[0001] The utility model relates to the technical field of sealing joints, in particular to a sealing joint for pipe splicing. Background Art

[0002] When splicing two or more pipe fittings together, a sealing joint body is required to connect the two pipe fittings and ensure the sealing effect of the connection to prevent liquid or gas leakage. At present, there are many types of sealing joint bodies on the market, suitable for different pipe materials, pressure levels, medium characteristics and installation environments. However, when connecting pipe fittings of different models and sizes, different specifications of sealing joint bodies are required to adapt to the model size of the pipe fittings, and the versatility of the sealing joint body is poor.

[0003] In order to solve the above problems, we propose a sealing joint for pipe splicing, and the sealing joint body can connect pipes of different models and sizes. Utility Model Content

[0005] The utility model is implemented through the following technical approach: a sealing joint for pipe splicing, including a joint body and a transversely symmetrical swivel, the transversely symmetrical swivel is rotatably connected to the two ends of the joint body, both sides of the joint body are rotatably connected to a plurality of arc plates, the tail ends of the plurality of arc plates are rotatably connected to clamping blocks, the inner wall of the swivel is fixedly connected to a plurality of extrusion blocks, the extrusion blocks are extrusion-matched with the adjacent arc plates, both ends of the joint body are slidably connected to conical cylinders, a positioning component for positioning the swivel is provided on the joint body, a locking component is provided on the joint body and the conical cylinder, and the locking component is used to lock the position of the conical cylinder.

[0006] In one embodiment, the positioning assembly includes a laterally symmetrical sliding rod, which is slidably connected to both ends of the joint body, a first elastic member is connected between the sliding rod and the joint body, and a clamping block is fixedly connected to one side of the sliding rod close to the swivel.

[0007] In one of the embodiments, a circle of grooves adapted to the block is provided on one side of the rotating ring close to the block.

[0008] In one embodiment, the locking assembly includes a laterally symmetrical clamping rod, which is slidably connected to both ends of the joint body, a second elastic member is connected between the clamping rod and the joint body, a matching block is fixedly connected to the top end of the conical cylinder, the upper side surface of the matching block is inclined, and the matching block is squeezed and matched with the adjacent clamping rod.

[0009] In one of the embodiments, a circular hole matching with the clamping rod is opened on the matching block.

[0010] In one of the embodiments, it further comprises a transversely symmetrical sealing ring, wherein the transversely symmetrical sealing ring is fixedly connected to both ends of the connector body.

[0011] The utility model has the following advantages: 1. The pipe fittings are inserted from the left and right ends of the joint body so that the pipe fittings contact the tapered tube and push it to slide inward. After the tapered tube slides inward to a suitable position, the clamping block is controlled to move inward to fix the pipe fitting by rotating the swivel, thereby keeping the pipe fitting in a state of docking with the tapered tube. At the same time, a rubber layer is provided on the inner side of the tapered tube, which can also ensure the sealing effect between the pipe fitting and the tapered tube. The tapered tube is a tapered structure with a narrow inner side and a wide outer side, and can be docked with pipe fittings of different models and sizes.

[0012] 2. Through the cooperation of the clamping block and the clamping slot, the position of the swivel can be fixed after the swivel rotates to control the clamping block to fix the pipe fitting, to prevent the swivel from reversing and causing the clamping block to loosen, thereby affecting the fixing effect of the pipe fitting.

[0013] 3.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] Embodiment 1: A sealing joint for pipe splicing, such as Figure 1-Figure 7 As shown, it includes a joint body 1, a swivel 2, an arc plate 3, a clamping block 301, an extrusion block 4, a conical cylinder 5, a positioning assembly and a locking assembly. The left and right parts of the joint body 1 are rotatably connected with the swivel 2, and the left and right sides of the joint body 1 are rotatably connected with four arc plates 3 equidistantly distributed in the circumferential direction. The tail ends of the four arc plates 3 are rotatably connected with the clamping blocks 301. Four extrusion blocks equidistantly distributed in the circumferential direction are fixedly connected to the inner side of the swivel 2. The extrusion blocks 4 are extruded and matched with the adjacent arc plates 3. The left and right parts of the joint body 1 are slidably connected with the conical cylinder 5. A rubber layer is provided on the inner side of the conical cylinder 5. A positioning assembly for positioning the swivel 2 is provided on the joint body 1, and a locking assembly is provided on the joint body 1 and the conical cylinder 5. The locking assembly is used to lock the position of the conical cylinder 5.

[0024] When using the device, the staff will insert the pipe fittings to be spliced ​​from the left and right ends of the joint body 1 respectively, so that the pipe fittings are in contact with the tapered tube 5 and push it to slide inward. After the tapered tube 5 slides inward to a suitable position, the locking assembly is used to lock the position of the tapered tube 5. Then the staff rotates the swivel 2. The rotation of the swivel 2 drives the extrusion block 4 to rotate. The extrusion block 4 rotates to extrude the arc plate 3 inward. The inward rotation of the arc plate 3 drives the clamping block 301 to move inward to fix the pipe fitting, thereby keeping the pipe fitting in a state of docking with the tapered tube 5. Then the position of the swivel 2 is fixed by the positioning assembly. At the same time, a rubber layer is provided on the inner side of the tapered tube 5, which can also ensure the sealing effect between the pipe fitting and the tapered tube 5. The tapered tube 5 is a tapered structure with a narrow inside and a wide outside, which can be docked with pipe fittings of different models and sizes.

[0025] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, the positioning assembly includes a sliding rod 6, a first elastic member 7 and a clamping block 8. The left and right parts of the front side of the joint body 1 are slidably connected to the sliding rod 6. The first elastic member 7 is connected between the sliding rod 6 and the joint body 1. The sliding rod 6 is fixedly connected to the clamping block 8 on one side of the swivel 2. The swivel 2 is provided with a circle of clamping grooves adapted to the clamping block 8 on one side of the swivel 2.

[0026] When using the device, when the swivel 2 rotates, the block 8 will be squeezed to move inward, and the inward movement of the block 8 drives the sliding rod 6 to slide inward, and the first elastic member 7 is deformed. When the clamping block 301 moves inward to fix the pipe, the swivel 2 stops rotating. Under the action of the first elastic member 7 resetting, the sliding rod 6 drives the block 8 to move outward and re-engage in the slot of the swivel 2, thereby fixing the position of the swivel 2 to prevent the swivel 2 from reversing and causing the clamping block 301 to loosen, affecting the fixing effect of the pipe.

[0027] like Figure 1 and Figure 7 As shown, the locking assembly includes a clamping rod 9, a second elastic member 10 and a matching block 101. The upper part of the joint body 1 is slidably connected to a left-right symmetrical clamping rod 9, a second elastic member 10 is connected between the clamping rod 9 and the joint body 1, and a matching block 101 is fixedly connected to the upper side of the conical cylinder 5. The upper side surface of the matching block 101 is inclined, the matching block 101 is squeezed and matched with the adjacent clamping rod 9, and a circular hole matching the clamping rod 9 is opened on the matching block 101.

[0028] like Figure 4 As shown, a sealing ring 11 is also included, and the sealing ring 11 is fixedly connected to the left and right parts of the joint body 1.

[0029] When using the device, the conical tube 5 slides inwards and fits with the sealing ring 11 installed in the joint body 1, and the gap between the conical tube 5 and the joint body 1 is sealed by the sealing ring 11. When the conical tube 5 slides inwards, it will also drive the matching block 101 to move inwards. When the matching block 101 moves inwards and contacts with the clamping rod 9, the matching block 101 will squeeze the clamping rod 9 to slide upward, and the second elastic member 10 will be deformed. When the clamping rod 9 moves to the position of the circular hole of the matching block 101, under the action of the resetting of the second elastic member 10, the clamping rod 9 slides downward and is clamped into the circular hole, and then the position of the conical tube 5 is fixed by the matching block 101, ensuring that the conical tube fits with the sealing ring, further ensuring the sealing effect.
