DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 3 As shown, the utility model provides an air tightness tester for general instrument detection, comprising a lower bracket 1, a top plate 2, an electric telescopic rod 3, a clamp 4, an air inlet pipe 5, an air outlet pipe 6 and a balloon 7. The electric telescopic rod 3 is fixedly installed on the left and right sides of the top of the lower bracket 1, the bottom of the top plate 2 is fixedly connected to the end of the electric telescopic rod 3 away from the lower bracket 1, the clamp 4 is movably installed on the left and right sides of the inner wall of the lower bracket 1, the air inlet pipe 5 is connected to the right side of the top of the top plate 2, the air outlet pipe 6 is connected to the left side of the top of the top plate 2, the balloon 7 is sleeved on the end of the air outlet pipe 6 away from the lower bracket 1, a movable groove 8 is opened at the bottom of the inner wall of the lower bracket 1, a support plate 9 is arranged inside the movable groove 8, a support assembly 10 is movably connected to the top of the support plate 9, and a sliding assembly 11 is fixedly connected to the left and right sides of the inner wall of the movable groove 8.

[0024] refer to Figure 2 The support assembly 10 includes a rotating pin 101 , a fixing plate 102 is fixedly connected to the top of the rotating pin 101 , and a rotating disk 103 is fixedly connected to the top of the fixing plate 102 .

[0025] As a technical optimization solution of the utility model, by setting up a support assembly 10, the turntable 103 is used to place the instrument to be tested, and the rotating pin 101 is used to connect the support plate 9 and the fixed plate 102. At the same time, the rotating pin 101 is used to facilitate the user to rotate the fixed plate 102. The rotation of the fixed plate 102 can drive the turntable 103 to rotate, thereby facilitating the user to adjust the direction of the instrument and making it easier for the clamp 4 to clamp the instrument.

[0026] refer to Figure 2 and Figure 3 The sliding assembly 11 includes a slide bar 111 , and slide rails 112 are provided on the left and right sides of the support plate 9 . The inner wall of the slide rail 112 is slidably connected to the surface of the slide bar 111 .

[0027] As a technical optimization scheme of the utility model, by setting a sliding component 11, the slide bar 111 can slide inside the slide rail 112 by moving the support plate 9, and the slide rail 112 can limit the slide bar 111 up and down. Conversely, the up, down, left and right limits of the slide bar 111 can limit the support plate 9 up and down, and the up and down limits of the support plate 9 can limit the turntable 103 up and down, thereby improving the stability and movement efficiency of the support plate 9 and the turntable 103 moving forward and backward.

[0028] refer to Figure 2 The top of the rotating disk 103 is fixedly connected to a limiting ring 12, and the surface of the limiting ring 12 is fixedly connected to a rotating rod 13. A plurality of rotating rods 13 are provided and are distributed in a ring shape with equal distances.

[0029] As a technical optimization solution of the utility model, by setting a limit ring 12 and a rotating rod 13, the limit ring 12 can limit the instrument on the top of the turntable 103, thereby preventing the turntable 103 from moving and causing the instrument to tip over. The rotating rod 13 facilitates the user to rotate the limit ring 12 and the turntable 103, thereby making it easier for the user to adjust the direction of the instrument.

[0030] refer to Figure 2 A fixing groove 14 is provided on the top of the turntable 103 , and an anti-skid pad 15 is fixedly connected to the inner wall of the fixing groove 14 , and the material of the anti-skid pad 15 is rubber.

[0031] As a technical optimization solution of the utility model, by setting a fixing groove 14 and an anti-skid pad 15, the fixing groove 14 can fix and limit the anti-skid pad 15, and the anti-skid pad 15 can avoid improving the stability of the bottom of the instrument. At the same time, the rubber anti-skid pad 15 can avoid hard friction between the instrument and the turntable 103.

[0032] refer to Figure 1 and Figure 2 Through holes 16 are provided on both sides of the front side of the support plate 9, and the inner wall of the through hole 16 is slidably connected with a guide rod 17, and the two ends of the guide rod 17 are fixedly connected to the front side and the rear side of the inner wall of the movable groove 8 respectively.

[0033] As a technical optimization scheme of the utility model, by setting a through hole 16 and a guide rod 17, the through hole 16 can limit the guide rod 17 up, down, left, and right. Conversely, the up, down, left, and right limits of the guide rod 17 can limit the support plate 9 up, down, left, and right. This improves the stability of the support plate 9. At the same time, the guide rod 17 guides the support plate 9, thereby preventing the support plate 9 from moving and deviating, causing the slide bar 111 and the slide rail 112 to get stuck.

[0034] refer to Figure 1Two connecting rods 18 are fixedly connected to the front side of the support plate 9. The other end of the connecting rod 18 passes through the lower bracket 1 and is fixedly connected to a handle 19. The connecting rod 18 is movably connected to the lower bracket 1.

[0035] As a technical optimization solution of the utility model, a connecting rod 18 and a handle bar 19 are provided, and the connecting rod 18 is used to connect the handle bar 19 and the support plate 9, so that the user can adjust the position of the support plate 9. The user can push and pull the handle bar 19 to drive the connecting rod 18 and the support plate 9 to move forward and backward, so that the user can adjust the position of the turntable 103 and the instrument placed on the top thereof.

[0036] The working principle and use process of the utility model are as follows: when in use, the user first places the instrument to be tested for air tightness on the top of the turntable 103, and then pushes the rotating rod 13 to drive the limit ring 12 and the turntable 103 to rotate, so that the user can adjust the direction and opening position of the instrument. Then, the user pushes and pulls the handle 19 to drive the connecting rod 18 and the support plate 9 to move forward and backward. The forward and backward movement of the support plate 9 can drive the fixing plate 102 and the turntable 103 to move forward and backward. When the opening at the top of the instrument is between the air inlet pipe 5 and the outlet pipe, the user can adjust the direction and opening position of the instrument by pushing and pulling the handle 19. When the top plate 2 reaches the bottom of the air tube 6, stop moving the handle 19, and then start the electric telescopic rod 3 so that the output end of the electric telescopic rod 3 drives the top plate 2 to move downward. When the bottom of the top plate 2 is tightly fitted with the opening of the instrument, close the electric telescopic rod 3. At this time, inject gas into the air inlet pipe 5 to make the gas pass through the inside of the instrument and the air outlet pipe 6 into the inside of the balloon 7 to inflate the inside of the balloon 7. Then close the air inlet pipe 5 and observe the size of the balloon 7. If the balloon 7 becomes smaller, it means that there is a problem with the air tightness of the instrument. If the volume of the balloon 7 remains unchanged, it means that the air tightness of the instrument is good.

[0037] To sum up: this is a general instrument detection airtightness tester, by setting a movable groove 8 and a support plate 9, the support plate 9 can be used to support the instrument, and the support plate 9 can move forward and backward inside the movable groove 8, so as to facilitate the user to adjust the position of the instrument, and solve the problem that the positions of the protective cotton and the clamping frame of the device are relatively fixed, and the sizes and shapes of various instruments are different. Similarly, the positions and sizes of the openings on the top of the instruments are also different. Therefore, the user needs to adjust the position of the instrument when fitting the opening on the top of the instrument and the sealing cotton, and the space between the descending top plate and the lower bracket is small, which makes the operation inconvenient.
