Description

Technical Field

[0001] The utility model relates to the technical field of groove connectors, in particular to a novel groove connector with a pipe clamp inner cavity. Background Art

[0002] Grooved connectors are a new type of steel pipe connection, also known as clamp connections, which have many advantages. In the design specifications for automatic sprinkler systems and the technical specifications for fire water supply and fire hydrant systems, the connection of system pipes should be made with grooved connectors or threaded or flanged connections. Among them, pipes with a diameter equal to or greater than 100 mm in the automatic sprinkler system and pipes with a diameter greater than 50 mm in the fire water supply system should be connected in sections with flanges or grooved connectors.

[0003] Common groove connectors are generally composed of two sets of upper and lower pipe clamps. When in use, the two sets of upper and lower pipe clamps are assembled at the connection of the pipe mouth, and then the upper and lower pipe clamps are fixed by bolts. However, in order to enhance the sealing performance, a sealing gasket is added inside the groove connector during assembly. However, the sealing gasket will age and shrink after long-term decoration, and the groove connector will not be frequently disassembled after assembly, resulting in the groove connector losing good sealing performance on the pipeline, thereby causing water leakage. The working requirements of the groove connector cannot be met. Therefore, a new groove connector with a pipe clamp inner cavity is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a novel groove connector with a pipe clamp inner cavity to solve the technical problem that the sealing gasket will age and shrink during long-term decoration, causing the groove connector to lose its good sealing performance on the pipeline.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new groove connector with a pipe clamp inner cavity, comprising:

[0008] A clamp, wherein the middle part of the outer side and the left and right sides of the clamp are connected with columns, and an outer sealing ring is installed at the middle position of the inner side of the clamp;

[0009] The inner sealing ring is inserted in the middle position of the outer sealing ring, and the bottom of the inner cavity of the column is inserted with a connecting plate, and the inner end of the connecting plate is connected to the corresponding position inside the inner sealing ring;

[0010] The ratchet plate is installed on the left and right sides of the inner cavity of the column. Springs are connected to the outside of the inner cavity of the column. The inner ends of the springs are all installed with U-shaped frames. The left and right sides of the U-shaped frames are both inserted with locking teeth through bearings.

[0011] Preferably, the number of the springs is 2-4 groups. The tips of the teeth of the ratchet plate are all arranged downward. The shapes of the locking teeth all correspond to the tooth grooves of the ratchet plate, preventing the connecting plate from moving upward.

[0012] Preferably, the number of the columns is 2-5 groups. The inner walls of the pipe clamps are all coated with corrosion-resistant coatings. The outer sealing ring is made of hard rubber material, and the inner sealing ring is made of soft rubber material, improving the sealing performance of the groove.

[0013] Preferably, bolt grooves are opened on the left and right sides of the pipe clamp. Insertion holes are opened on the left and right sides inside the bolt grooves. Plug rods are inserted inside the insertion holes.

[0014] Preferably, the right ends of the plug rods are all rounded, making it smoother for the plug rods to be inserted into the insertion holes. The left ends of the plug rods are all connected with L-shaped baffles, and anti-slip ridges are installed on the tops of the L-shaped baffles, facilitating the pushing and pulling of the L-shaped baffles.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a new type of groove connector with a pipe clamp inner cavity, having the following beneficial effects:

[0017] For the new type of groove connector with a pipe clamp inner cavity, after the outer sealing ring and the inner sealing ring are added and the pipe clamp is assembled, the outer sealing ring and the inner sealing ring are stuck at the connection of the pipe orifice. When the inner sealing ring shrinks due to corrosion or wear, under the action of the spring, the U-shaped frame and the connecting plate can be pushed to descend, thereby pushing the inner sealing ring to be pressed tightly. And due to the existence of the ratchet plate and the locking teeth, the inner sealing ring can always be closely attached to the surface of the pipe connection port, improving the sealing performance of the groove connector and avoiding repeated disassembly and repair.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution, a new type of grooved connector with a pipe clamp inner cavity, including a clamp 1, a connector column 2, a connector outer sealing ring 3, a connector inner sealing ring 4, a connector connecting plate 5, a connector ratchet plate 6, a connector spring 7, a connector U-shaped frame 8, a connector locking tooth 9, a connector bolt groove 10, a connector jack 11, a connector plug rod 12 and an L-shaped baffle 13:

[0027] Please refer to Figure 1 , the middle part and the left and right sides of the outside of the clamp 1 are both connected with columns 2. Please refer to Figure 2 , an outer sealing ring 3 is installed at the middle position inside the clamp 1;

[0028] Please refer to Figure 3 , an inner sealing ring 4 is inserted at the middle position inside the outer sealing ring 3. The inner cavities of the columns 2 are both inserted with connecting plates 5, and the inner ends of the connecting plates 5 are both connected to the corresponding positions inside the inner sealing ring 4;

[0029] Please refer to Figure 4 , a ratchet plate 6 is installed on the left and right sides of the inner cavity of the column 2. Springs 7 are both connected to the outside of the inner cavity of the column 2, and the inner ends of the springs 7 are both installed with U-shaped frames 8. Please refer to Figure 5, on both the left and right sides of the U-shaped frame 8, there are engaging teeth 9 inserted through bearings. The number of springs 7 is 2 - 4 groups. The tips of the ratchet plates 6 are all arranged downward. The shapes of the engaging teeth 9 all correspond to the tooth grooves of the ratchet plates 6. The number of columns 2 is 2 - 5 groups. The inner walls of the clamps 1 are all coated with corrosion-resistant coatings. The outer sealing rings 3 are made of hard rubber, and the inner sealing rings 4 are made of soft rubber. After the clamp 1 is assembled, the added outer sealing rings 3 and inner sealing rings 4 can be stuck at the connection of the pipe opening. When the inner sealing ring 4 shrinks due to corrosion or wear, it can push the U-shaped frame 8 and the connecting plate 5 to descend under the action of the spring 7, thereby pushing the inner sealing ring 4 to be pressed tightly. And due to the existence of the ratchet plate 6 and the engaging teeth 9, the inner sealing ring 4 can always closely adhere to the surface of the pipe connection port, improving the sealing performance of the grooved connector and avoiding repeated disassembly and repair.

[0030] Please refer to Figure 6 , on both the left and right sides of the clamp 1, there are bolt grooves 10 opened. On both the left and right sides inside the bolt grooves 10, there are insertion holes 11 opened. Inside the insertion holes 11, there are insertion rods 12 inserted. The right ends of the insertion rods 12 are all rounded. The left ends of the insertion rods 12 are all connected with L-shaped baffles 13, and there are anti-slip ridges installed on the tops of the L-shaped baffles 13. The connection of the L-shaped baffles 13 can be completed by inserting the insertion rods 12 into the insertion holes 11. Thus, the L-shaped baffles 13 can protect the bolts and nuts inside the bolt grooves 10, preventing them from rusting and facilitating the disassembly and assembly of the clamp 1.

[0031] In this solution, after the clamp 1 is assembled, the added outer sealing rings 3 and inner sealing rings 4 can be stuck at the connection of the pipe opening. When the inner sealing ring 4 shrinks due to corrosion or wear, it can push the U-shaped frame 8 and the connecting plate 5 to descend under the action of the spring 7, thereby pushing the inner sealing ring 4 to be pressed tightly. And due to the existence of the ratchet plate 6 and the engaging teeth 9, the inner sealing ring 4 can always closely adhere to the surface of the pipe connection port, improving the sealing performance of the grooved connector and avoiding repeated disassembly and repair.
