Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and more specifically, to a rubber pipe airtightness testing fixture. Background Technology

[0002] Before rubber pipes leave the factory, they need to undergo an air tightness test. The traditional testing method uses a conical connector, with the large-diameter end connected to the air source and the small-diameter end inserted into the pipe. One end of the pipe is then blocked, air is pumped into the pipe, and pressure is maintained for a period of time. If the air pressure remains constant, the pipe is considered airtight; if the air pressure drops, the pipe is considered defective. This testing method has problems: the conical connector is prone to falling off the pipe during the pressurization process, requiring the conical connector to be reinserted and the pipe to be re-inflated. Furthermore, it requires manual clamping of the pipe opening onto the conical connector, making the process cumbersome and inefficient. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rubber pipe airtightness testing fixture, which aims to improve the technical problems of cumbersome operation and low efficiency in the existing pipe airtightness testing.

[0004] This utility model is implemented as follows: a rubber pipe airtightness testing fixture includes a base with a groove, an air inlet pipe installed at the bottom of the groove, an air inlet connector connected to one end of the air inlet pipe extending into the groove, hydraulic cylinders arranged on both sides of the groove on the base, and clamping blocks movably arranged on both sides of the air inlet connector inside the groove, with the piston rod of the hydraulic cylinder connected to the clamping blocks.

[0005] Furthermore, a stepped groove is provided at one end of the air intake pipe that extends into the groove, and the two ends of the air intake connector include a connecting pipe and an air outlet pipe, with the connecting pipe inserted into the stepped groove.

[0006] Furthermore, the outer wall of the air outlet pipe is further provided with protruding strips.

[0007] Furthermore, the clamping block includes a movable block with a vertical semi-circular groove, and a trapezoidal insert with a semi-circular notch is further installed on the movable block.

[0008] Furthermore, a guide post is provided on the inner sidewall of the groove, and a guide hole is opened on the movable block, through which the guide post passes.

[0009] The beneficial effects of this utility model are: This utility model discloses a rubber pipe airtightness testing fixture with a simple structure and ingenious design. It includes a base with a groove, an air inlet pipe installed at the bottom of the groove, and an air inlet connector connected to one end of the air inlet pipe extending into the groove. Hydraulic cylinders are installed on both sides of the groove, and clamping blocks are movably installed on both sides of the air inlet connector within the groove. The piston rods of the hydraulic cylinders are connected to the clamping blocks. In use, one end of the pipe is closed, and the other end is opened and inserted into the air inlet connector. Then, the hydraulic cylinders are controlled to push the clamping blocks to clamp the pipe at the air inlet connector. Air is introduced into the pipe from the air inlet pipe at the bottom of the groove, achieving pipe airtightness testing. The air inlet connector allows for quick connection of the air pipe, and the clamping blocks allow for quick clamping of the air pipe opening at the air inlet connector. The operation is simple and improves testing efficiency. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] Please refer to Figure 1-3This utility model provides a rubber pipe airtightness testing fixture, including a base 10 with a groove 101. An air inlet pipe 104 is installed at the bottom of the groove 101. One end of the air inlet pipe 104 extending into the groove 101 is connected to an air inlet connector 105. Specifically, the end of the air inlet pipe 104 extending into the groove 101 has a stepped groove. The air inlet connector 105 includes a connecting pipe and an air outlet pipe at both ends. The connecting pipe is inserted into the stepped groove and is interference-fitted with the stepped groove. The lower end of the air inlet pipe 104 is connected to an external air source. The pipe opening is covered by the air inlet connector 105, and the gas enters the pipe through the air inlet pipe 104 and then through the air inlet connector 105. The air inlet connector 105 and the air inlet pipe 104 are detachably connected, allowing for the replacement of different sized air inlet connectors 105 according to different pipe sizes, thus improving the practicality of the test. Furthermore, a raised strip is provided on the outer wall of the air outlet pipe. When the pipe is fitted into the air inlet connector 105, the raised strip plays an anti-slip role, so that the pipe opening can be tightly fitted into the air inlet connector 105.

[0017] Please refer to Figure 1-3 The base 10 has hydraulic cylinders 102 on both sides of the groove 101. Clamping blocks 103 are movably mounted on both sides of the air inlet connector 105 within the groove 101. The piston rod of the hydraulic cylinder 102 is connected to the clamping blocks 103. Specifically, the clamping block 103 includes a movable block with a vertical semi-circular groove. A trapezoidal insert with a semi-circular notch is further installed on the movable block. After the pipe opening is fitted into the air inlet connector 105, the hydraulic cylinder 102 is controlled to push the two movable blocks to close. The vertical semi-circular groove serves to avoid obstruction. The two trapezoidal inserts clamp the pipe at the air inlet connector 105. The semi-circular notch can just clamp the pipe at the air inlet connector 105. The trapezoidal inserts can be changed to different sizes according to different air inlet connectors 105, further improving the practicality of the clamping.

[0018] Furthermore, a guide post is provided on the inner side wall of the groove 101, and a guide hole is opened on the moving block. The guide post passes through the guide hole, and the oil cylinder 102 drives the moving block to move in the groove 101. The two moving blocks can close precisely. The movement of the moving block along the guide post can prevent the moving block from deviating and causing the pipe to fail to be pressed tightly at the air inlet joint 105.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
