Description

Technical Field

[0001] This utility model relates to the field of pressure gauge connection technology, and in particular to a pressure gauge connection component. Background Technology

[0002] Pressure gauge connection assemblies are devices used to reliably connect pressure gauges to pipes or equipment interfaces. They are widely used in petrochemical, energy, and machinery manufacturing industries. By adapting to different interface specifications, they ensure accurate transmission of pressure signals and guarantee stable system operation and efficient management in industrial process monitoring, equipment safety protection, and fluid control maintenance. Existing pressure gauges mainly involve wrapping waterproof tape around the connection point and screwing the pressure gauge into the connection through the thread of the connector. The tape's compression prevents water leakage. However, this structure requires manual wrapping of the tape and screwing in of the pressure gauge, resulting in slow installation speed and low efficiency. Therefore, the aforementioned problems need to be improved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5This utility model discloses a pressure gauge connection assembly, including a pressure gauge 1. A connecting pipe is installed at the lower end of the pressure gauge 1. An annular groove is formed on the outer side of the lower end of the connecting pipe, and a sealing structure is installed below the connecting pipe. A connecting structure is installed outside the sealing structure. The connecting structure includes a connector 2 sleeved on the lower end of the connecting pipe, which facilitates the connection of various components. Four mounting grooves are formed on the outer side of the upper end of the connector 2, and an annular sliding groove is formed on the outer side of the lower end of the connector 2, which facilitates the sliding connection between the sleeve 3 and the connector 2. The mounting grooves are used to install... There is a locking steel ball 4, one end of which is placed in the annular groove of the connecting pipe. The locking steel ball 4 is used to lock the pressure gauge 1 into the annular groove. The lower inner side of the connector 2 has a threaded groove, and the upper end of the threaded groove has a guide groove. The outer side of the connector 2 is fitted with a sleeve 3. The sleeve 3 is slidably connected in the slide groove through a limiting block. A first spring 5 is installed on the top surface of the limiting block. The two ends of the first spring 5 are fixed to the sleeve 3 and the connector 2 respectively. The upper end of the sleeve 3 has a limiting groove. The first spring 5 is used to make the sleeve 3 automatically spring back.

[0020] In this utility model, the sealing structure includes a sealing block 7 placed in the guide groove. The sealing block 7 has a T-shaped cross-section, and a sealing ring 8 is installed on the outer side of the lower end of the sealing block 7. The sealing block 7 and the sealing ring 8 facilitate the sealing of the guide groove. A slider 9 is installed on the upper end of the sealing block 7, which facilitates the movement of the sealing block 7. A connecting frame is fixedly connected to the middle of the slider 9. The bottom surface of the connecting frame is fixedly connected to the top surface of the sealing block 7, and a second spring 6 is provided on the periphery of the bottom surface of the slider 9. The two ends of the second spring 6 are fixedly connected to the bottom surface of the slider 9 and the inner wall of the connector 2, respectively. The second spring 6 facilitates the self-locking of the connection structure and the insertion and removal of the pressure gauge 1.

[0021] Working principle: When using this utility model, first connect the lower end of connector 2 to the water pipe. Then pull down the sleeve 3 and press the lower end of pressure gauge 1 into connector 2. At this time, the lower end of the connecting pipe presses the slider 9 down and pushes the locking steel ball 4 outward into the limiting groove. Then release the sleeve 3 and continue to press down the pressure gauge 1. At this time, the sealing block 7 moves downward under the action of the slider 9, so that the sealing structure opens. When the annular groove and the mounting groove are on the same horizontal plane, the sleeve 3 rebounds under the action of the first spring 5 and drives the locking steel ball 4 to move inward and lock into the annular groove. At this time, the pressure gauge 1 is fixed and starts to work. When it is necessary to remove the pressure gauge 1, pull down the sleeve 3. At this time, the second spring 6 rebounds and drives the pressure gauge 1 and the slider 9 to move upward, which in turn causes the locking steel ball 4 to move outward under the action of the slider 9, and drives the sealing block 7 and the sealing ring 8 to move upward to prevent water from overflowing. At this time, the sleeve 3 can be released and the pressure gauge 1 can be removed.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
