Description

Technical Field

[0001] This utility model relates to the field of dental medical device manufacturing technology, and in particular to a dental solenoid valve airtight leak detection clamp. Background Technology

[0002] In the field of dental medical device manufacturing, solenoid valves are key components in many devices, and their airtightness directly affects the stability and safety of the equipment. Dental treatment processes place stringent demands on the precision and reliability of the equipment. If a solenoid valve has airtightness defects, it will not only affect the normal operation of the equipment but may also lead to deviations in the treatment process, affecting the treatment outcome and even causing patient discomfort or safety issues.

[0003] The existing dental solenoid valve airtight leak detection fixture has poor sealing performance, and gas leakage may occur during testing. It has significant limitations and poor practicality. Moreover, the traditional dental solenoid valve airtight leak detection fixture is difficult to adapt to the pace of large-scale, mass production, and is therefore not very practical. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor sealing performance in the existing technology, which may lead to gas leakage in the solenoid valve during testing, resulting in significant limitations and difficulty in adapting to large-scale, batch production, and poor practicality. Therefore, this invention proposes a dental solenoid valve airtight leak detection fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dental solenoid valve airtight leak detection clamp, comprising a base plate, a front positioning plate at the top of the base plate, a rear positioning plate fixed at one side of the top of the base plate, an air inlet screw hole at one end of the front positioning plate, an air inlet channel at one end of the front positioning plate located within the air inlet screw hole, a guide hole at the outer side of the air inlet channel located within the front positioning plate, a plurality of positioning small shafts installed within the rear positioning plate, a plurality of air inlet small shafts installed within the front positioning plate, and a first sealing gasket and a second sealing gasket respectively installed on the inner side of the opposite ends of the positioning small shafts and the air inlet small shafts.

[0006] Preferably, a cylinder seat plate is fixed to the top of the base plate, a cylinder body is installed at one end of the cylinder seat plate, the output end of the cylinder body passes through the cylinder seat plate and is fixed to the front positioning plate, and guide rods are installed on both sides of the end of the cylinder seat plate facing the front positioning plate.

[0007] Preferably, the guide hole matches the guide rod.

[0008] Preferably, brackets are bolted to both ends of the base plate.

[0009] Preferably, a mounting plate is fixed to the bottom surface of each of the two brackets at the end away from the base plate.

[0010] Preferably, a gap is left between the front positioning plate and the rear positioning plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the dental solenoid valve is placed at a position defined by the front and rear positioning plates. Precise positioning is achieved through the positioning shaft and the air inlet screw hole. The cylinder body, supported by the cylinder seat plate, extends and retracts under the guidance of the guide rod. The front positioning plate moves towards the rear positioning plate and clamps the solenoid valve. Through the setting of the first and second sealing gaskets, the front and rear positioning plates fit tightly against the solenoid valve during the clamping process, forming a sealed space. Gas enters the air intake channel through the air inlet screw hole and the air intake shaft, and then flows into the inside of the solenoid valve or related detection parts. The air tightness of the solenoid valve is determined by detecting changes in gas pressure. This device, through the setting of the first and second sealing gaskets and the clamping action of the cylinder body, forms a reliable seal. Compared with traditional devices, it can more effectively prevent gas leakage and improve the accuracy of air tightness detection. This device, through the setting of multiple sets of first and second sealing gaskets, can simultaneously seal and clamp multiple solenoid valves and can simultaneously detect multiple solenoid valves.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a dental solenoid valve airtight leak detection fixture, including a base plate 1, a front positioning plate 2 at the top of the base plate 1, a rear positioning plate 6 fixed at one side of the top of the base plate 1 on the front positioning plate 2, an air inlet screw hole 11 at one end of the front positioning plate 2, an air inlet channel 13 at one end of the air inlet screw hole 11 in the front positioning plate 2, a guide hole 14 at the outside of the air inlet channel 13 in the front positioning plate 2, a plurality of positioning small shafts 7 installed in the rear positioning plate 6, a plurality of air inlet small shafts 12 installed in the front positioning plate 2, and a first sealing gasket 8 and a second sealing gasket 10 respectively installed on the inner side of the opposite end of the positioning small shafts 7 and the air inlet small shafts 12.

[0021] The overall effect of Embodiment 1 is that the dental solenoid valve is placed in the position determined by the front positioning plate 2 and the rear positioning plate 6. Precise positioning is achieved through the setting of the positioning shaft 7 and the air inlet screw hole 11. Through the setting of the first sealing gasket 8 and the second sealing gasket 10, during the clamping process of the front positioning plate 2 and the rear positioning plate 6, they are tightly fitted with the solenoid valve to form a sealed space. Gas enters the air intake channel 13 through the air inlet screw hole 11 and the air intake shaft 12, and then enters the interior of the solenoid valve or related detection parts. The air tightness of the solenoid valve is determined by detecting changes in gas pressure. This device, through the setting of the first sealing gasket 8 and the second sealing gasket 10, and in conjunction with the clamping action of the cylinder body 4, forms a reliable seal. Compared with traditional devices, it can more effectively prevent gas leakage and improve the accuracy of air tightness detection. Through the setting of multiple sets of first sealing gaskets 8 and second sealing gaskets 10, this device can simultaneously seal and clamp multiple solenoid valves and can simultaneously detect multiple solenoid valves.

[0022] Example 2, as Figure 1-4As shown, a cylinder seat plate 3 is fixed to the top of the base plate 1. A cylinder body 4 is installed at one end of the cylinder seat plate 3. The output end of the cylinder body 4 passes through the cylinder seat plate 3 and is fixed to the front positioning plate 2. Guide rods 5 are installed on both sides of the end of the cylinder seat plate 3 facing the front positioning plate 2. The guide hole 14 matches the guide rod 5. Brackets 9 are installed at both ends of the base plate 1 by bolts. Mounting plates are fixed to the bottom surface of the two brackets 9 away from the base plate 1. A gap is left between the front positioning plate 2 and the rear positioning plate 6.

[0023] The overall effect of embodiment 2 is that the guide rod 5 and guide hole 14 can stabilize and guide the movement of the front positioning plate 2. The bracket 9 and its fixed mounting plate facilitate the installation and removal of the base plate 1. The gap between the front positioning plate 2 and the rear positioning plate 6 facilitates the installation of the solenoid valve.

[0024] Working principle: When using this device, the dental solenoid valve is placed in the position determined by the front positioning plate 2 and the rear positioning plate 6. Precise positioning is achieved through the positioning shaft 7 and the air inlet screw hole 11. The cylinder body 4, supported by the cylinder seat plate 3, extends and retracts under the guidance of the guide rod 5. The push plate, front positioning plate 2, moves towards the rear positioning plate 6, clamping the solenoid valve. Through the setting of the first sealing gasket 8 and the second sealing gasket 10, during the clamping process of the front positioning plate 2 and the rear positioning plate 6, they fit tightly against the solenoid valve, forming a sealed space. Gas passes through the air inlet screw hole 11. 1. The intake shaft 12 enters the intake channel 13 and then passes into the solenoid valve or related detection parts. By detecting changes in gas pressure, the device determines whether the solenoid valve has an airtightness problem. This device forms a reliable seal through the setting of the first sealing gasket 8 and the second sealing gasket 10, and in conjunction with the clamping action of the cylinder body 4. Compared with traditional devices, it can more effectively prevent gas leakage and improve the accuracy of airtightness detection. This device can simultaneously seal and clamp multiple solenoid valves by setting multiple sets of first sealing gaskets 8 and second sealing gaskets 10, and can detect multiple solenoid valves at the same time.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
