Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and more specifically, it relates to a press-fit grooved reducer. Background Technology

[0002] Pipeline systems are a common method of water transportation. Depending on the structure of different water-using equipment, water pipes of different diameters are required, thus necessitating the use of pipes with different diameters for connection.

[0003] There are many common pipe connection methods, including threaded connections, grooved connections, press-fit connections, and welding. Among these, grooved connections and press-fit connections are the most common. Generally, pipe fittings will only use one connection method. However, in actual use, multiple pipes need to be installed as adapters, but the connection structures of the pipes are not standardized. Common reducers also only have one connection method, which limits the types of pipes that can be used, restricting their application. Moreover, grooved connections require clamps for complete fixation. Most common grooved connections are separate from the clamps and placed independently, with the corresponding clamps only installed during connection. Therefore, the parts are stored separately, and if left idle for a long time, some parts are easily lost during storage or movement, rendering the equipment unusable and inconvenient. In addition, the general adapter structure is relatively simple, with most reducers being tee structures. However, in actual operation, three flow directions may not be needed, or two flow directions and three directional keys may be required for switching, which is not conducive to operation.

[0005] To address the problems existing in the prior art, this utility model provides a press-fit grooved reducing connector to solve the technical problem mentioned in the background art that the reducing connector has a simple structure but is inconvenient to use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a press-fit grooved reducer, comprising a pipe body, a connector on the pipe body, multiple connectors having different diameters, a press-fit portion at the outer end of the connector, an inner groove on the side of the connector away from the press-fit portion, a clamp on the outer side of the pipe body, the clamp engaging with the inner groove, a support ring inside the connector, a sealing ring outside the support ring engaging with the support ring, an inner convex ring inside the clamp engaging with the inner groove via the inner convex ring, and a mating groove inside the clamp engaging with the press-fit portion, adapting to the structure of the pipe body connector;

[0008] The connector head is provided with support frames at its upper and lower ends, and a sliding block is slidably connected in the support frames. The clamp includes an upper clamp and a lower clamp, and a connecting plate is provided at one end of the upper clamp and the lower clamp. The connecting plate is rotatably engaged with the sliding block.

[0009] The present invention is further configured such that a ball valve block is provided inside the pipe body, a three-way hole is provided in the ball valve block, and a control handle is provided on the pipe body. The control handle cooperates with the ball valve block to facilitate control of the flow direction.

[0010] The present invention is further provided that the control handle is provided with an identification groove, which cooperates with the three-way hole to facilitate workers to distinguish the status of the ball valve block.

[0011] The present invention is further provided that the control handle has anti-slip texture on the side end to facilitate operation of the control handle.

[0012] The present invention is further configured such that a filter frame is provided between the support ring and the sealing ring, and a filter screen is provided in the filter frame to provide a filtration effect.

[0013] The present invention is further configured such that the sealing ring includes an annular ring, and an extension ring is provided on the inner side of the annular ring. The extension ring cooperates with the filter frame to increase the sealing effect.

[0014] The present invention is further configured such that the upper clamp is provided with fastening bolts at both ends, and the lower clamp is provided with extended threaded rings at both ends.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a press-fit grooved reducer, which has the following advantages:

[0017] 1. By engaging with the connector through the clamping part and the inner groove, two connection structures are provided: a clamp connection structure through the engagement of the clamp and the inner groove, and a clamping connection method through the clamping part. This allows for two common connection methods. In practical use, it is more necessary to use the appropriate connection structure to connect pipe fittings, thereby improving applicability, reducing limitations in use, and facilitating use.

[0018] 2. The support frame, sliding block, and connecting plate cooperate with the clamp to form a connection structure, so that the clamp composed of the upper and lower clamps is integrated with the connector and can be rotated. This does not affect the clamping connection and ensures that the grooved connection structure is integrated, avoiding the adverse effects of missing parts and making it convenient to use.

[0019] 3. The ball valve block cooperates with the three-way port to provide a guiding structure. The control handle cooperates with the ball valve block for control. The valve body structure set in the pipe body is adjusted to control the flow direction of the internal guide, so as to realize the connection of different directions and different pipe ports, which facilitates the use of the equipment.

[0029] Please see Figure 1-5 A press-fit grooved reducer includes a pipe body 1, a connector 2 on the pipe body 1, multiple connectors 2 with different pipe diameters, a press-fit part 3 at the outer end of the connector 2, an inner groove 4 on the side of the connector 2 away from the press-fit part 3, a clamp 5 on the outer side of the pipe body 1, the clamp 5 cooperating with the inner groove 4, a support ring 6 inside the connector 2, a sealing ring 7 on the outer side of the support ring 6, and the sealing ring 7 cooperating with the support ring 6.

[0030] The connector 2 is provided with support frames 8 at the upper and lower ends. A sliding block 9 is slidably connected in the support frame 8. The clamp 5 includes an upper clamp 10 and a lower clamp 11. A connecting plate 12 is provided at one end of the upper clamp 10 and the lower clamp 11.

[0032] More specifically, the support frame 8 provides intermediate support, and the sliding block 9 and connecting plate 12 are used for connection. The clamp 5 is connected to the connector 2 without the need for a separate clamp 5 device. By controlling the connecting plate 12 to rotate along the sliding block 9, the connecting plate 12, along with the upper clamp 10 and lower clamp 11, rotates away from the connection point between the connector 2 and the pipe, facilitating assembly and the operation of the clamping tool. After assembly, the upper clamp 10 and lower clamp 11 are controlled to rotate horizontally toward the connector 2.

[0035] Please see Figures 4-5As a further implementation of the control handle: the control handle 15 is provided with an identification groove 16, which cooperates with the three-way hole 14.

[0036] Specifically, the marking groove 16 provides a prompt function to help users determine the distribution direction of the tee hole 14.

[0037] Please see Figure 1 As a further embodiment of the control handle: the control handle 15 has anti-slip texture 17 on its side end.

[0038] Specifically, the anti-slip texture 17 provides an anti-slip effect, making it easier to rotate the control handle 15.

[0039] Please see Figure 2 As a further embodiment of the clamp: the clamp 5 has an inner protruding ring 18 on its inner side, the clamp 5 cooperates with the inner groove 4 through the inner protruding ring 18, the clamp 5 has a mating groove 19 inside, and the mating groove 19 cooperates with the clamping part 3.

[0040] Specifically, the inner convex ring 18 and the inner groove 4 cooperate to fix the connected connector 2 and the pipe, while the mating groove 19 will cooperate with the clamping part 3 to adapt to the protruding structure of the clamping part 3, so that the clamp 5 is stably fixed.

[0041] Please see Figures 2-3 As a further embodiment of the support ring: a filter frame 20 is provided between the support ring 6 and the sealing ring 7, and a filter screen 21 is provided in the filter frame 20.

[0042] Specifically, the filter frame 20 provides support, enabling the filter screen 21 to provide a filtration effect.

[0043] Please see Figure 3 As a further embodiment of the sealing ring: the sealing ring 7 includes an annular ring 22, and an extension ring 23 is provided on the inner side of the annular ring 22, the extension ring 23 cooperating with the filter frame 20.

[0044] Specifically, the annular ring 22 cooperates with the support ring 6, and the extension ring 23 guides the filter frame 20 and the tube body 1 to improve the sealing effect.

[0045] Please see Figures 1-2 As a further embodiment of the clamp: the upper clamp 10 is provided with fastening bolts 24 at both ends, and the lower clamp 11 is provided with extended threaded rings 25 at both ends, the extended threaded rings 25 cooperating with the fastening bolts 24.

[0046] Specifically, the fastening bolt 24 is installed on the upper clamp 10, not prepared separately for easy use, and a longer thread structure is provided by the extended threaded ring to cooperate with the fastening bolt 24.

[0047] In summary, during the use or operation of the overall equipment:

[0048] When using the equipment, the structure provided by the pipe body 1 allows the filter frame 20 to be rotated into the connector 2 and supported by the support ring 6, enabling the filter screen 21 to provide filtration. The sealing ring 7 is then installed into the connector 2 and supported by the support ring 6. The pipe to be installed is then inserted into the corresponding connector 2. The structure provided by the clamping part 3 allows the equipment to clamp the connector 2 and the installed pipe body 1. When the clamp 5 is installed into the connector 2, the inner groove 4 cooperates with the clamp 5 to fix the connector 2 and the pipe body 1 together. The connection of the pipe is kept stable through the cooperation of two sets of limiting structures. The annular ring 22 cooperates with the support ring 6, and the extension ring 23 guides the pipe body 1 towards the filter frame 20 and the pipe body 1, improving the sealing effect.

[0049] When connecting and fixing the clamp 5, the support frame 8 provides intermediate support, and the sliding block 9 and connecting plate 12 cooperate to connect the clamp 5 to the connector 2. There is no need to prepare the clamp 5 separately. By controlling the connecting plate 12 to rotate along the sliding block 9, the connecting plate 12 will rotate along with the upper clamp 10 and lower clamp 11, thus moving them away from the connection point between the connector 2 and the pipe, which facilitates the assembly and clamping tool operation. After assembly, control the upper clamp 10 and lower clamp 11 to rotate horizontally towards the connector 2. The sliding block 9 moves along the support frame 8 to make slight height adjustments, which facilitates the alignment and mating of the clamp 5 and the connector 2. When the clamp 5 and the connector 2 are mated, the inner convex ring 18 and the inner groove 4 cooperate to fix the connected connector 2 and the pipe. The mating groove 19 will cooperate with the clamping part 3 to adapt to the protruding structure of the clamping part 3, so that the clamp 5 is stably fixed. The fastening bolt 24 is installed on the upper clamp 10. It is not prepared separately for easy use, and the extended threaded ring provides a longer thread structure to cooperate with the fastening bolt 24.

[0050] In the use of the equipment, the ball valve block 13 provides the valve function, the anti-slip texture 17 provides the anti-slip effect, making it easy to rotate the control handle 15, and the marking groove 16 provides the prompt function, making it easy for the user to judge the distribution direction of the three-way hole 14, so that the three-way hole 14 can be matched with different connectors 2 to provide a channel. By rotating the ball valve block 13, the pipe body 1 is guided in a specific direction.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
