Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to an airtightness detection device. Background Technology

[0002] In the coffee machine manufacturing and maintenance industry, the steam pipe, as a core component, is responsible for generating and delivering high-temperature steam for milk frothing or cleaning operations. Its airtightness directly affects the coffee machine's efficiency, energy consumption, and user safety. Leaks in the steam pipe not only lead to steam pressure loss, affecting coffee quality, but can also pose safety hazards, such as burns from leaking steam. Therefore, accurate airtightness testing of the steam pipe is a crucial step in the production process and quality control. Currently, the industry commonly uses an airtightness tester as the testing tool. Gas is introduced into the steam pipe through a gas delivery pipe, and pressure changes are monitored to assess the seal, thereby ensuring that the product meets standards.

[0058] Reference Figures 1 to 5 The following is a further description of an embodiment of the airtightness testing device of the present invention.

[0059] An airtightness testing device includes an airtightness meter 1 and a gas supply pipe 2, the gas supply pipe 2 being fixedly connected to the airtightness meter 1; it also includes: a support block 3, disposed on the gas supply pipe 2 and fixedly connected to the gas supply pipe 2; an arc-shaped plate 4, disposed on the support block 3 and made of rubber material, used to connect and fix the steam pipe; a clamping frame 5, disposed on the airtightness meter 1 and fixedly connected to the airtightness meter 1; two clamping rings 6, symmetrically disposed on the clamping frame 5, used to clamp and fix the steam pipe; a clamping mechanism, disposed within the clamping frame 5, used to clamp and fix the steam pipe; and a fixing mechanism, disposed on the support block 3, used to connect and fix the steam pipe and the gas supply pipe 2.

[0060] Reference Figure 4 In a preferred embodiment, the clamping mechanism includes: a clamping rod 7, disposed within the clamping frame 5 and fixedly connected to the clamping frame 5; a clamping sleeve 8, slidably connected to the clamping rod 7 and slidably connected to the clamping frame 5; a clamping disc 9, fixedly connected to the clamping sleeve 8; and an elastic component disposed on the clamping sleeve 8.

[0061] During operation, press the clamping plate 9 to move it closer to the clamping frame 5, causing the clamping sleeve 8, which is fixedly connected to the clamping plate 9, to slide on the clamping rod 7 and the clamping frame 5.

[0062] Reference Figure 4In a preferred embodiment, the elastic component includes: an elastic block 10, which is disposed on the clamping sleeve 8, fixedly connected to the clamping sleeve 8, and slidably connected to the clamping frame 5; an elastic spring 11, one end of which is fixedly connected to the elastic block 10, and the other end of which is fixedly connected to the clamping frame 5; and a rotating component disposed on the elastic block 10.

[0063] During operation, the elastic block 10, which is fixedly connected to the clamping sleeve 8, slides within the clamping frame 5, thereby causing the elastic spring 11, which is fixedly connected to the elastic block 10, to be compressed, generating elastic potential energy.

[0064] Reference Figure 4 In a preferred embodiment, the rotating component includes: two first rotating shafts 12, which are symmetrically arranged on the elastic block 10 and fixedly connected to the elastic block 10; a rotating plate 13, which is rotatably connected to the first rotating shafts 12; a second rotating shaft 14, which is rotatably connected to the rotating plate 13; a sliding groove 15, which is formed on the clamping frame 5; and two sliding blocks 16, which are symmetrically arranged in the sliding groove 15, slidably connected to the sliding groove 15, and fixedly connected to the second rotating shaft 14 and the clamping ring 6.

[0065] During operation, the rotating plate 13, which is rotatably connected to the first rotating shaft 12, rotates, causing the sliding block 16, which is fixedly connected to the second rotating shaft 14, to slide in the sliding groove 15, so that the clamping ring 6, which is fixedly connected to the sliding block 16, moves away from each other.

[0066] Reference Figure 5 In a preferred embodiment, the fixing mechanism includes: a fixing shaft 17, which is disposed on the support block 3 and fixedly connected to the support block 3; a fixing block 18, which is fixedly connected to the fixing shaft 17; and a moving component, which is disposed on the support block 3.

[0067] During operation, rotating the fixed block 18 causes the fixed shaft 17, which is fixedly connected to the fixed block 18, to rotate on the support block 3.

[0068] Reference Figure 5 In a preferred embodiment, the moving component includes: a moving groove 19, which is formed on the support block 3; two moving blocks 20, which are symmetrically arranged in the moving groove 19, slidably connected to the moving groove 19, and threadedly connected to the fixed shaft 17; a moving plate 21, which is disposed on the moving block 20, fixedly connected to the moving block 20, and fixedly connected to the arc plate 4; and a transmission component, which is disposed on the support block 3.

[0069] During operation, the movable block 20, which is threadedly connected to the fixed shaft 17, rotates, causing the movable block 20 to slide in the movable groove 19, so that the movable blocks 20 move closer to each other, causing the movable plate 21, which is fixedly connected to the movable block 20, to move, so that the arc plate 4, which is fixedly connected to the movable plate 21, moves closer to each other.

[0070] Reference Figure 5 In a preferred embodiment, the transmission component includes: a transmission groove 22 formed on the support block 3; a transmission rod 23 disposed in the transmission groove 22 and fixedly connected to the support block 3; two transmission blocks 24, which are symmetrically disposed in the transmission groove 22, slidably connected to the transmission groove 22, and slidably connected to the transmission rod 23; and a transmission spring 25 disposed in the transmission groove 22 and fixedly connected to the transmission blocks 24.

[0071] During operation, the transmission block 24, which is fixedly connected to the moving plate 21, slides on the transmission rod 23 in the transmission groove 22, causing the transmission spring 25 to contract elastic potential energy.

[0072] Working principle: In use, first connect the steam pipe to the gas supply pipe 2, then rotate the fixed block 18, which drives the fixed shaft 17 fixedly connected to the fixed block 18 to rotate on the support block 3, causing the moving block 20 threadedly connected to the fixed shaft 17 to rotate, causing the moving block 20 to slide in the moving groove 19, so that the moving blocks 20 move closer to each other, causing the moving plate 21 fixedly connected to the moving block 20 to move, so that the arc plate 4 fixedly connected to the moving plate 21 moves closer to each other, thereby causing the transmission block 24 fixedly connected to the moving plate 21 to slide on the transmission rod 23 in the transmission groove 22, causing the transmission spring 25 to contract its elastic potential energy, thereby clamping and fixing the steam pipe. This prevents the connection between the steam pipe and the gas supply pipe 2 from becoming loose, which affects the accuracy of the test.

[0073] Next, after connecting the steam pipe to the airtightness tester 1, press the clamping disc 9 to move it closer to the clamping frame 5. This causes the clamping sleeve 8, which is fixedly connected to the clamping disc 9, to slide on the clamping rod 7 and the clamping frame 5. This causes the elastic block 10, which is fixedly connected to the clamping sleeve 8, to slide within the clamping frame 5. This causes the elastic spring 11, which is fixedly connected to the elastic block 10, to be compressed, generating elastic potential energy. This causes the rotating plate 13, which is rotatably connected to the first rotating shaft 12, to rotate. This causes the sliding block 16, which is fixedly connected to the second rotating shaft 14, to slide within the sliding groove 15. This causes the clamping rings 6, which are fixedly connected to the sliding block 16, to move away from each other. Then, the steam pipe is placed into the clamping rings 6. The clamping disc 9 is then released, causing the elastic spring 11 to release its elastic potential energy. This causes the clamping rings 6 to move closer together until they contact the surface of the steam pipe. This clamps and fixes the steam pipe, preventing it from shaking and affecting the detection of the steam pipe.

[0074] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
